  By the way, medical carts may come into contact with people or objects, or frequently move and suddenly stop, not only during long-distance movements but also on medical sites, and placed on the shelf of medical carts. There is a risk that equipment such as the processor unit will fall from the shelf board. In the medical cart described in Patent Document 1, the screen is lowered to shield the equipment when the equipment is not in use or moved for a long distance, but the universal cord of the endoscope is connected to the equipment at the medical site. In this state, it is necessary to raise the screen and expose the equipment, which is absolutely useless for preventing the equipment from falling.

  Furthermore, in the state where the screen is raised and the equipment is exposed, when the endoscope just pulled out from the patient's body cavity is hung on the hanger of the medical cart, the distal end portion of the endoscope soiled with dirt, etc. There is also a risk of contaminating these by coming into contact with the equipment mounted on the shelf or the edge of the shelf.

  The present invention has been made in view of the above problems, and provides a medical cart capable of preventing equipment from falling while being used as well as being used, and preventing contamination of equipment and the like due to filth and the like. The purpose is to do.

  In order to achieve the above object, the medical cart of the present invention includes a bottom plate having moving wheels attached to the bottom, a top plate on the top, and a column that connects the bottom plate and the top plate with a space therebetween. , A cart body that is attached to an intermediate portion of the column so as to partition the bottom plate and the top plate, and a shelf plate on which medical equipment is placed, and is detachably covered on the outside of the cart body, It is characterized by comprising a cover member that covers at least a part between the bottom plate and the top plate together with a shelf plate, and a window portion provided in at least a part of the cover member.

  The cover member has a cylindrical shape that is loosely fitted on the peripheral surfaces of the top plate, the shelf plate, and the bottom plate, and a first engagement means that engages with the top plate at an upper portion of the cover member. It is preferable that the lower part has a second engaging means for engaging with the bottom plate.

  The first engaging means is connected to the upper part of the cover member, and has a frame-like shape that comes into contact with the peripheral part of the top surface of the top plate with a substantially constant width in a state where the cover member is placed on the cart body. It is preferable that it is a frame part.

  The second engaging means is preferably a hole that is formed in a lower portion of the cover member and engages with a hook attached to a peripheral surface of the bottom plate in a state where the cover member is covered with the cart body. .

  According to the medical cart of the present invention, the cover member is detachably placed on the outer side of the cart body, shields at least the bottom plate and the top plate of the cart body together with the shelf board, and is opened and closed through the window portion. Since part of the equipment can be exposed, it is possible to prevent the equipment from falling while the equipment is being used as well as moving, and to prevent the equipment from being contaminated by filth.

  In FIG. 1 showing the first embodiment of the present invention, a medical cart 11 is fixed to a substantially rectangular bottom plate 13 having casters (wheels) 12 at four corners, and to the back side of both sides of the bottom plate 13, A pair of struts 14 arranged toward the top, and a substantially rectangular top plate 15 fixed to the upper end portions of the pair of struts 14 on the back side of both sides, and the top plate 15 and the bottom plate 13 are partitioned. A cart main body 18 composed of first and second shelf boards 16 and 17 having a substantially rectangular shape fixed to the middle part of the pair of support posts 14 on the back side of both sides, and detachably attached to the outside of the cart main body 18. A cover sheet 19 (cover member) having a cylindrical shape that covers and covers medical equipment and the like placed on the top surfaces of the bottom plate 13 and the shelf plates 16 and 17 is formed. In the present embodiment, the sizes of the bottom plate 13, the shelf plates 16 and 17, and the top plate 15 are the same.

  The cover sheet 19 is a sheet formed of a transparent or translucent resin having waterproofness and chemical resistance, such as a thermoplastic polyurethane elastomer or a silicone-modified thermoplastic polyurethane elastomer, and is attached to the bottom plate 13 and the shelf plates 16 and 17. The state of the mounted equipment can be seen and understood, and the equipment is protected from dust, water and filth. In addition, the cover sheet 19 is sturdy, hard to tear, and has an appropriate flexibility. Therefore, when the medical cart 11 comes into contact with an object or a person while moving, or the medical cart 11 is suddenly stopped. However, it prevents the internal equipment from falling from the bottom plate 13 and the shelf plates 16 and 17 and from being damaged. Hereinafter, the surface on the side opposite to the pair of support posts 14 on which the equipment is taken in and out is referred to as the front surface of the cover sheet 19, the side opposite to the front surface is the back surface, and the surface between the front surface and the back surface is the side surface.

  Each caster 12 is provided with a stop lever 20 for prohibiting its rotation. When the stop lever 20 is raised, the caster 12 cannot be rotated, and when the stop lever 20 is lowered, the caster 12 is allowed to rotate.

  Medical equipment such as a medical device is placed on the top surface of the bottom plate 13 and the shelf plates 16 and 17, and equipment such as relatively small tools such as forceps and tweezers is placed on the top surface of the top plate 15. Place. In the present embodiment, a well-known processor device 21 and a light source device 22 are placed on the upper surface of the first shelf plate 16 as medical equipment in a state of being overlapped.

  The processor device 21 is connected to a known endoscope (not shown) via a universal cord, captures an endoscopic image photographed by the endoscope, and places the image on a monitor 23 such as a liquid crystal display. Output. The light source device 22 is connected to the endoscope similarly to the processor device 21 and supplies illumination light for photographing to the endoscope.

  The monitor 23 is fixed to a stand 25 attached to one corner of the top surface of the top plate 15, and is connected to the processor device 21 via wiring in the stand 25. An endoscopic image output from the processor device 21 is displayed on the monitor 23. A hanger 27 that hangs the endoscope by hooking an operation portion (not shown) of the endoscope is detachably attached to another corner of the top surface of the top plate 15. The hanger 27 is attached to the top plate 15 by inserting the tip of the bar 27a into a hole formed in the top plate 15. When the bar 27a is pulled upward, the hanger 27 is removed from the top plate 15. Can do.

  When the endoscope is hung on the hanger 27, an insertion portion (not shown) of the endoscope that is inserted into the body cavity of the patient hangs down to the side of the medical cart 11. For this reason, there is a risk that the filth attached to the insertion portion of the endoscope may adhere to the bottom plate 13, the shelf plates 16 and 17, and the equipment placed on the upper surface thereof, but these are shielded by the cover sheet 19. Therefore, these contaminations by filth are prevented.

  A rod-like handle 28 integrally provided with a pair of support members 28a is detachably attached to the peripheral surface of one side of the top plate 15. In this attachment / detachment mechanism, for example, a hole for receiving the tip of the support member 28a is formed on the peripheral surface of one side of the top plate 15, and the tip is locked when the tip of the support member 28a is inserted into this hole. Yes. Since this lock is released by pressing a release button provided on the edge of the top plate 15, if the handle 28 is pulled and the support member 28a is pulled out of the hole while pressing the release button, the handle 28 is removed from the top. It can be removed from the plate 15.

  The medical cart 11 can be moved freely by attaching the handle 28 to the top plate 15 and holding and pushing and pulling the handle 28 with the stop lever 20 lowered. An opening (not shown) through which the handle 28 is inserted is formed in a part of the rear upper portion of the cover sheet 19.

  A hook-shaped hook 31 for locking the cover sheet 19 is attached to the peripheral surface of the bottom plate 13. A total of eight hooks 31 are attached, two on each side of the bottom plate 13. The hook 31 is attached so that the tip thereof faces downward so that a round hole 19a (second engagement means) formed in the lower portion of the cover sheet 19 is engaged from below the cart body 18. The round holes 19a are respectively formed at positions corresponding to the respective positions of the hook 31, and a total of eight holes are formed. The periphery of the round hole 19a is reinforced with a donut-shaped patch 33.

  The cover sheet 19 has a cylindrical shape that covers substantially the entire cart body 18 except for the top surface of the top plate 15 and the bottom surface of the bottom plate 13. A frame-shaped frame portion 19b (first engagement means) having a rectangular shape that contacts with a certain width is provided continuously. The frame portion 19b abuts on the peripheral edge of the upper surface of the top plate 15 to prevent the cover sheet 19 from shifting downward, and the upper portion of the cover sheet 19 is positioned with respect to the cart body 18.

  Further, since the frame portion 19 b has a rectangular shape corresponding to the top plate 15, the cover sheet 19 may be shifted in the circumferential direction of the cart body 18 in a state where the cover sheet 19 is placed on the cart body 18. Is prevented. Moreover, since most of the upper surface of the top plate 15 is exposed by the opening 19c of the frame portion 19b, medical instruments such as forceps and tweezers can be placed on the upper surface of the top plate 15 without any trouble.

  On the front surface of the cover sheet 19, the cover plate 19 was placed on the upper surfaces of the bottom plate 13 and the shelf plates 16 and 17 at positions corresponding to the three sections divided by the bottom plate 13, the shelf plates 16 and 17, and the top plate 15. Openable and closable windows 19d, 19e, and 19f that can be accessed while the cover sheet 19 is covered on the cart body 18 are provided.

  The window portions 19d, 19e, and 19f are formed by making a U-shaped cut on the front surface of the cover sheet 19 so as to be opened and closed from below, and attaching fasteners 35 to 37 having a waterproof function to the cut. ing. By operating the sliders 35a to 37a of the fasteners 35 to 37, the windows 19d, 19e, and 19f can be opened and closed, respectively.

  When an endoscope is connected to the processor device 21 and the light source device 22 placed on the upper surface of the first shelf board 16, the window portion 19d is opened by operating the slider 35a. The degree of opening should be minimized as much as possible, so that the universal cord of the endoscope connected to the processor device 21 and the light source device 22 is inserted. In the present embodiment, since no equipment is placed on the bottom plate 13 and the second shelf plate 17, the windows 19 e and 19 f are kept closed to prevent dust and dirt from entering the cover sheet 19. To prevent.

  In order to cover the cover sheet 19 on the cart body 18, the processor device 21 and the light source device 22 are placed on the upper surface of the first shelf 16 in advance. After removing the hanger 27 and the handle 28 from the top plate 15, it is confirmed that the front surface of the cover sheet 19 is the front side of the processor device 21 and the light source device 22, and the cover sheet 19 is opposite to the opening 19c. The top 19 of the cart body 18 and the monitor 23 are covered from the opening 19g side. At this time, since the monitor 23 is sufficiently smaller than the size of the opening 19g, it does not get in the way.

  Subsequently, when the edge of the cover sheet 19 on the opening 19 g side is held and pulled down, the entire circumference of the cart body 18 is covered with the cover sheet 19, and the frame portion 19 b is a peripheral portion of the upper surface of the top plate 15. Abut. If the lowering of the cover sheet 19 is stopped in this state, each of the round holes 19a faces each of the corresponding hooks 31.

  From this state, using the flexibility of the cover sheet 19, the edge on the side of the opening 19g is pulled and pulled down so that the position of the round hole 19a is slightly below the position of the hook 31, so that the round hole 19a Pass the tip of hook 31 through. When the pulling of the edge on the opening 19 g side of the cover sheet 19 is stopped, the edge on the opening 19 g side rises, the round hole 19 a engages with the hook 31, and the cover sheet 19 is attached to the cart body 18. Thereafter, if the hanger 27 and the handle 28 are attached to the top plate 15, the medical cart 11 can be used.

  The engagement between the round hole 19a and the hook 31 prevents the cover sheet 19 from shifting upward, and the contact between the peripheral edge of the top plate 15 and the frame portion 19b causes the cover sheet 19 to shift downward. Therefore, even when the medical cart 11 is moving, the mounting state of the cover sheet 19 on the cart body 18 is kept substantially constant.

  After confirming that the windows 19d, 19e, 19f are closed, the handle 28 is grasped and pushed while the stop lever 20 is lowered, and the medical cart 11 is moved to a desired medical site. During this time, even if the medical cart 11 comes into contact with a person or an object, or the medical cart 11 is suddenly stopped, the processor device 21 or the light source device 22 may move. The device 22 contacts the inner surface of the cover sheet 19 and does not fall from the first shelf board 16.

  When arriving at the medical site, the stop lever 20 is raised to lock the caster 12 so that the medical cart 11 does not move carelessly. The slider 35a is operated to open the window portion 19d, and the universal cord of the endoscope is connected to the processor device 21 and the light source device 22. Thereafter, the slider 35a is operated to adjust the opening degree of the window portion 19d to the minimum necessary so that the universal cord is inserted. Since the windows 19e and 19f do not need to be opened, they are kept closed. If the cover sheet 19 is pressed from above the window portion 19d with a finger, the cover sheet 19 is bent and the buttons disposed on the front surfaces of the processor device 21 and the light source device 22 can be operated.

  When the endoscope is used and lowered to the hanger 27, the insertion portion of the endoscope to which dirt is attached may come into contact with the side surface or the front surface of the cover sheet 19, but the cover sheet 19 is waterproof. The dirt does not penetrate into the cover sheet 19 and the internal processor device 21 and the light source device 22 are not contaminated. After the use of the medical cart 11 is finished, if the dirt attached to the cover sheet 19 is wiped clean and disinfected with alcohol or the like, the cover sheet 19 can be used cleanly over a long period of time.

  In addition, after removing the hanger 27 and the handle 28 from the top plate 15, the engagement between the round hole 19 a and the hook 31 is released, and the cover sheet 19 is pulled upward to remove the cover sheet 19 from the cart body 18. Can be easily replaced with another new cover sheet.

  In addition, medical equipment such as the processor device 21 and the light source device 22 is preferably placed on the top surfaces of the shelf boards 16 and 17 and the bottom plate 13 before the cover sheet 19 is put on the cart body 18, but the window portion 19d. If the equipment is of a size that can be taken in and out of -19f, the cover sheet 19 may be placed on the shelf boards 16 and 17 after the cover sheet 19 is placed on the cart body 18.

  Next, a second embodiment of the present invention will be described with reference to FIG. The medical cart 41 is configured to have a cart main body 42 having the same configuration as that of the first embodiment, and a detachable cover on the outer side of the cart main body 42, and has an opening in the upper portion, similar to the cover sheet 19 described above. Net 43 (cover member). The net 43 is drawn with a rough mesh for easy understanding on the drawing, but actually, it is knitted with a very fine mesh.

  In the net 43, the knitting yarn constituting the net 43 is made of a material having flexibility, durability, and water resistance such as a thermoplastic polyurethane elastomer and a silicone-modified thermoplastic polyurethane elastomer, like the cover sheet 19 of the first embodiment. Since it is formed, a certain degree of waterproofness is secured in combination with the fineness of the mesh. This level of waterproofness means that it is an effective level within the treatment time. If filth and water are applied to the outer surface of the net 43, the filth and water will move from the mesh to the inside of the net 43 over time. Therefore, it is desirable to remove the net 43 from the cart body 42 and clean the net 43 promptly after the treatment is completed, because there is a possibility that the equipment placed on the shelf plate of the cart body 42 may be contaminated.

  Moreover, since the net 43 is formed of a material having high elasticity, the net 43 can be freely recessed by pressing the net 43 with a fingertip. As a result, the equipment placed on the shelf plate of the cart body 42 can be operated while the cart body 42 is still covered with the net 43.

  For example, when the net 43 is made of a conductive fiber in which 99% purity silver is coated on nylon as the knitting yarn, the electromagnetic wave emitted from the equipment can be prevented from affecting the patient, and the electromagnetic wave sensitivity that is rarely present can be prevented. Preferred for patients with illness.

  Hooks 46 and 47 similar to the hook 31 described above are attached to the front and rear sides of the peripheral surfaces of the top plate 44 and the bottom plate 45 constituting the cart body 42. A total of four hooks 46 are provided, two on each of the front side and the rear side. Similarly, four hooks 47 are provided. Further, the hook 46 is attached so that the tip side is directed upward, and the hook 47 is attached so that the tip side is directed downward, contrary to the hook 46.

  When the net 43 is attached to the cart body 42, the net 43 is covered from above the cart body 42, first the mesh of the upper part of the net 43 is engaged with the hook 46, and then the hook 47 is below the net 43. By engaging the mesh of the part, the net 43 is appropriately pulled between the hooks 46 and 47, and is attached to the cart body 42 without loosening.

  For example, when connecting a universal cord (not shown) of an endoscope to the processor device 50 and the light source device 51 as medical equipment placed on the upper surfaces of the first and second shelf boards 48 and 49, Using the elasticity of the knitting yarn of the net 43, the mesh of the net 43 (corresponding to the “window”) in front of the processor device 50 and the light source device 51 is spread using a jig or the like, and an endoscope is formed from this mesh. Plug in the universal cord. Thereafter, the mesh is closed so as to be in close contact with the outer periphery of the universal cord due to the elasticity of the knitting yarn, so that there is no possibility that dirty water or the like enters from the mesh and contaminates the processor device 50 and the light source device 51.

  In the first embodiment described above, in order to position the upper portion of the cover sheet, the frame-like frame portion is continuously provided on the upper portion of the cover sheet. However, the present invention is not limited to this, for example, Similarly to the second embodiment, a hook may be attached to the peripheral surface of the top plate, and a hole that engages with the hook may be formed in the upper portion of the cover sheet. In addition, although this hole may be a round hole like the said embodiment, a rectangular shape may be sufficient, for example.

  Moreover, in order to position the upper part of a cover sheet, you may make it press the upper part of a cover sheet against the surrounding surface of a top plate with a rubber band. Moreover, you may make it connect the upper part of a cover sheet to the peripheral part of a top plate with a string. Further, a strong magnet may be attached to the upper part of the cover sheet, and this magnet may be attracted to a metal plate attached to the peripheral surface of the top plate. A point fastener (snap button) may also be used. These positioning means can be used as they are for positioning the lower part of the cover sheet.

  In the first embodiment, the cover sheet is mounted so as to be covered from above the cart body. However, the present invention is not limited to this. For example, a cut is made in the longitudinal direction on the back surface of the cover sheet, and a fastener is formed at the cut. By attaching the cover sheet, the cover sheet may be opened and closed from the back side to the left and right, and the cover sheet may be mounted from the front side of the cart body. If it does in this way, attachment or detachment of a cover sheet can be performed, without removing a hanger and a handle. Therefore, in this case, the hanger and the handle may be fixed.

  In the first embodiment, the U-shaped slit of the window portion is formed so as to open and close the window portion from the lower side. However, the present invention is not limited to this. A cut may be formed so as to open and close from the side. In addition, the fastener is used to open and close the window, but the present invention is not limited to this. For example, an opening is formed in the cover sheet, and a separate lid is detachably attached thereto. Also good. Moreover, although the thing with a waterproof function was used as a fastener, depending on the position of a window part, even if it is not necessarily a fastener with a perfect waterproof function, it can be used.

  In the first embodiment, eight hooks are provided in total, two for each side of the bottom plate. However, the present invention is not limited to such numerical values. Similarly, a hook may not be provided on the side surface side of the cart body, and two hooks may be provided on the front side and the back side, for a total of four. Alternatively, the hook may be provided not on the peripheral surface of the bottom plate but on the bottom surface of the bottom plate, and the lower edge of the cover sheet may be folded toward the bottom surface of the bottom plate so that the round hole formed in the edge is engaged with the hook. A snap button may be used instead of the hook.

  In the first embodiment, the cover sheet is formed of a transparent or translucent resin sheet. However, the present invention is not limited to this. For example, only the front surface of the cover sheet is transparent and the other portions are opaque. Alternatively, the whole may be formed of an opaque resin sheet or a water repellent cloth.

  If the entire cover sheet is made of an opaque resin sheet or a water-repellent cloth, the internal state cannot be observed, but anxiety is felt by seeing medical equipment and other equipment before surgery. The effect of suppressing anxiety can be expected for patients. In addition, since there are rarely patients with electromagnetic wave hypersensitivity, it is desirable to provide the cover sheet with an electromagnetic wave prevention function.

  In the above embodiment, examples of the material for the cover sheet and the net include a thermoplastic polyurethane elastomer and a silicone-modified thermoplastic polyurethane elastomer, but the present invention is not limited to this, and has transparency. Any material that is flexible, durable, and water resistant may be used. In the case of a net, since the state inside from the mesh is almost known, the material does not necessarily need to be transparent.

  In the embodiment described above, the number of shelf plates that partition the bottom plate and the top plate is two, but the present invention is not limited to this, and may be one or three, for example. Moreover, in the said embodiment, although the processor apparatus and the light source device were mentioned as an example of the equipment mounted in a shelf board, this invention is not limited to this, What is medical equipment, what kind? Equipment may be used.

It is a perspective view showing the appearance of the medical cart which is the 1st embodiment of the present invention. It is a side view which shows the external appearance of the medical cart which is 2nd Embodiment of this invention.
