Description

  The present invention relates to an antiseptic solution applicator.

  In surgery and surgical procedures, in order to prevent wound contamination and bacterial infection, first, disinfection around the incision site of a patient is performed. For example, in thoracotomy, the entire region is disinfected from the chest to the abdomen. At present, disinfection is performed as follows. First, a disinfectant solution is put into a tray containing cotton balls, the cotton balls are grasped and taken out with forceps or the like, applied to the patient's skin with a cotton ball infiltrated with the disinfectant solution, and disinfected.

  In such a disinfecting method, the disinfecting solution disappears from the cotton ball or the like as it is applied to the patient. Therefore, each time the cotton ball or the like has to be immersed in the disinfecting solution, it takes time and effort to disinfect. Further, since the disinfectant solution gradually comes out from the cotton ball or the like, uneven coating such as blurring occurs. For this reason, it is difficult to grasp how far the sterilization has been performed, and there is a possibility that a part with insufficient sterilization may occur. Furthermore, since the tray is prepared with an excessive amount of disinfectant, the disinfectant that has not been used cannot be reused, and it cannot be determined how much disinfectant was needed. It was consumed in vain.

  For this reason, there has been proposed an applicator that can continuously apply a disinfectant (Patent Document 1).

(Embodiment 1)
As shown in FIGS. 1 and 2, the disinfectant application device 1 according to Embodiment 1 includes a main body member 10, a lid member 20, and an application member 30.

  The main body member 10 has a bottomed cylindrical shape with one side opened. On the outer peripheral surface of the opening of the main body member 10, there is a main body fitting portion 11 protruding substantially over the entire circumference. The main body member 10 is formed in a funnel shape having a large diameter on the opening side so that it can be easily filled with a disinfectant and can be easily held and applied.

  The main body member 10 is made of a soft resin material such as polypropylene or polyethylene that can be crushed by hand. Moreover, the main body member 10 is formed of a transparent material that is colorless and transparent or colored and transparent so that the disinfecting liquid to be filled can be visually recognized.

  Further, the main body member 10 has a contact preventing portion 12. The contact prevention unit 12 functions to prevent the user's gloves from coming into contact with the edge of the lid member 20 and being damaged. The contact prevention unit 12 also functions as an anti-slip when the disinfectant application device 1 is held.

  Moreover, as shown in FIGS. 1-3, the side surface of the main body member 10 has the pump part 14 which is flat and formed thinner than the thickness of another site | part.

  Further, a scale 13 is attached to the pump part 14 on the side surface of the main body member 10 so that the capacity of the filled disinfectant can be visually recognized. The scale 13 is raised from the pump part 14 in a convex shape. In addition, the convex scale 13 is not provided in the curved side surface part of the main body members 10 other than the pump part 14. This is because, if there is a convex scale 13 other than the pump portion 14, the side surface of the main body member 10 is reinforced, and the deformation of the main body member 10 is hindered.

  As shown in FIGS. 2 and 4, the lid member 20 is a bottomed cylindrical member. The inner peripheral surface of the cylindrical portion 22 of the lid member 20 has a lid fitting portion 23 that protrudes from the inner peripheral surface of the cylindrical portion 22 over substantially the entire circumference. The lid fitting part 23 is fitted with the main body fitting part 11 of the opening of the main body member 10. The lid fitting portion 23 may be partially cut away. Thereby, the lid member 20 can be easily fitted into the main body member 10. Further, the bottom portion 21 of the lid member 20 is formed to be convexly curved from the periphery toward the center portion.

  The bottom portion 21 of the lid member 20 has a plurality of holes 24 through which disinfectant can pass. Here, eight circular holes 24 are arranged concentrically on the concentric circle, but may be any shape, number and arrangement as long as the disinfectant can pass through.

  The peripheral edge portion of the bottom portion 21 of the lid member 20 is formed in a taper shape that widens toward the cylindrical portion 22, and the portion formed in the taper shape serves as a joint portion 25 a with the application member 30. Further, the center portion of the bottom portion 21 of the lid member 20 is also provided with a joint portion 25b. The joint portion 25b in the central portion is a portion for injecting resin into the mold when the lid member 20 is molded using a mold, and a portion formed in a convex shape can be used. Moreover, it is preferable that the protrusion height of the junction part 25b of a center part is about 0.5-2 mm before welding with the application member 30. FIG.

  And the cover member 20 and the application | coating member 30 are joined in the location of junction part 25a, 25b, and the other location is not joined. For this reason, the periphery of the hole 24 of the lid member 20 and the coating member 30 are not joined. There is a gap between the bottom portion 21 of the lid member 20 and the coating member 30 except for the locations of the joint portions 25a and 25b.

  The application member 30 has a function of contacting the patient's skin and applying the disinfecting liquid filled in the main body member 10 to the patient. The applicator member 30 is required to have a characteristic that the disinfectant can be easily absorbed and can easily flow out when the disinfectant is applied to the patient. Moreover, since it is a site | part which contacts a patient's skin, it is requested | required that the touch should be good. Examples of such materials include polyurethane and polyethylene sponges and felts, as well as non-woven fabrics. The application member 30 is preferably a cosmetic sponge that is minimally invasive to the skin of the patient.

  The edge part of the application member 30 functions as the protection part 31 that has warped toward the lid member 20. The protective unit 31 prevents the lid member 20 from coming into contact with the patient's skin when the direction is changed during application of the disinfectant, and prevents the application member 30 from being wrapped or peeled off from the lid member 20. Functions as a site.

  In addition, when the application member 30 is joined to the lid member 20, a through hole 32 is formed at a location corresponding to the hole 24 of the lid member 20. The through-hole 32 is formed by punching with a diameter of about 1 to 3 mm at the time of formation, and is closed by the expansion force of the application member 30 after formation.

  The integration of the lid member 20 and the application member 30 can be performed as follows, for example. As shown in FIG. 5A, the disc-shaped application member 30 is disposed on the female mold 43 of the welding apparatus including the convex male mold 41 and the concave female mold 43. Further, the male mold 41 is inserted into the lid member 20.

  5B, when the male die 41 is pushed into the female die 43, the lid member 20 and the coating member 30 are pushed into the female die 43.

  A central portion of the male mold 41 is formed in a convex shape, and a heater 42 is installed inside the male mold 41. A heater 42 is also installed on the outer periphery of the male mold 41. The central portion and the peripheral portion of the bottom portion 21 of the lid member 20 are welded to the application member 30 by pressing by the male mold 41 and heating by the heater 42. In this manner, a part in which the lid member 20 and the application member 30 are integrated can be manufactured.

  In addition, although the method of integrating by thermal welding was demonstrated above, you may join the center part of the bottom part 21 of the cover member 20, the peripheral part, and the application | coating member 30 by other methods, such as ultrasonic welding.

  In addition, the through hole 32 of the application member 30 may be formed before being joined to the lid member 20 or after being joined to the lid member 20.

  The main body member 10, the lid member 20, and the application member 30 described above are sterilized. For this reason, even if a disinfectant is applied to a patient using the disinfectant application device 1, the disinfectant application device 1 prevents contamination of the patient's wound and bacterial infection.

  Then, the usage method of the disinfection liquid application instrument 1 is demonstrated. As shown in FIG. 6, first, the user fills the disinfectant from the opening of the main body member 10. Then, the user pushes the lid member 20 to which the application member 30 is bonded into the opening of the main body member 10. The lid member 20 is fixed to the main body member 10 by fitting the lid fitting portion 23 of the lid member 20 and the main body fitting portion 11 of the main body member 10.

  Since the lid member 20 is fixed to the main body member 10 simply by pushing the lid member 20 into the opening of the main body member 10, the disinfecting liquid applicator 1 can be easily assembled, so that the operation is not bothersome and time consuming. Moreover, since the contact prevention part 12 has protruded from the side surface of the main body member 10, when a user lifts the disinfecting liquid application instrument 1, it becomes slippery and it is suppressed that a user drops the disinfecting liquid application apparatus 1. .

  Then, the user holds the main body member 10, turns the application member 30 downward, and brings the application member 30 into contact with the skin HS of the patient. In addition, since the through hole 32 of the application member 30 is blocked by the expansion of the application member 30 while the application member 30 is brought into contact with the patient's skin HS downward, the disinfectant liquid leaks from the through hole 32. There is no.

  Then, as shown in FIG. 7, the disinfecting liquid in the main body member 10 penetrates the application member 30 through the holes 24, and the disinfecting liquid is discharged from the surface in contact with the patient's skin HS, so that the disinfecting liquid is removed from the patient. Applied to the skin HS.

  As described above, the application member 30 and the bottom portion 21 of the lid member 20 are not joined around the hole 24, and there is a gap between the application member 30 and the bottom portion 21 of the lid member 20. The disinfecting solution that has passed through penetrates the application member 30 so as to diffuse radially. Accordingly, the disinfectant liquid is quickly sucked into the application member 30. As a result, even if the disinfecting liquid is discharged from the applying member 30 by application, the disinfecting liquid is absorbed into the applying member 30 without any delay, so that the supply of the disinfecting liquid is rubbed with delay during application. Such a situation can be suppressed.

  Furthermore, since the through-hole 32 is formed in the application member 30, the application member 30 is ejected from the through-hole 32 that has been blocked by the expansion force of the application member 30 by the pressure of the disinfectant liquid by pressing the pump unit 14. So that the disinfectant is discharged.

  Thus, since the application member 30 is excellent in the absorption and discharge of the disinfectant, the disinfectant filled in the main body member 10 is applied to the patient without delay. Furthermore, since the main body member 10 is formed of a soft resin or the like and the thickness of the pump portion 14 is thin, when the user grips, the internal volume of the main body member 10 is easily reduced by the force. It deforms as follows. Since the internal pressure increases due to the deformation of the main body member 10, the discharge of the disinfecting liquid in the main body member 10 can be further promoted. Since a large amount of the disinfectant can be discharged without delay, the patient's skin can be disinfected so as to be washed away. By washing the patient's skin in this way, the disinfectant solution can enter the inside of the hair root and kill germs inside the hair root. In addition, the patient's skin HS has large irregularities such as ribs and navels, but the disinfectant application device 1 discharges a large amount of disinfectant even in such areas, so the disinfection of the skin HS is also disinfected. Can spread the liquid. Moreover, since the worker can apply the disinfectant application device 1 with one hand, it is excellent in workability.

  When the user applies the disinfectant to the patient, the disinfectant applicator 1 is reciprocated, so that the direction of the applicator member 30 is changed each time as shown in FIG. The application member 30 is joined to the peripheral edge portion of the bottom portion 21 of the lid member 20, and the periphery of the application member 30 is warped toward the main body member 10 as the protection portion 31, so that the application member 30 changes when the application direction changes. It is possible to prevent the application member 30 from being wrapped or peeled off from the lid member 20, thereby realizing a smooth application of the disinfectant. Therefore, the lid member 20 is not exposed, and the lid member 20 does not come into contact with the patient's skin HS to damage the skin HS.

  Further, the protective portion 31 on the periphery of the application member 30 can also prevent the lid member 20 from coming into contact with the patient's skin HS and damaging the skin during application.

  Moreover, since the application member 30 is joined to the bottom portion 21 of the lid member 20 by welding via the joint portions 25a and 25b, an excessive thickness of the application member 30 is not necessary. Since the thickness of the application member 30 is small and the volume is small, the amount of the disinfectant remaining on the application member 30 is reduced, so that wasteful consumption of the disinfectant can be suppressed. In addition, the thickness of the application member 30 is set to a thickness at which the user can easily perform the application work so that the patient does not feel uncomfortable, and is preferably about 3 to 10 mm.

  Furthermore, since the main body member 10 includes the contact prevention unit 12, the user's hand and fingers are prevented from contacting the lid member 20. The user wears surgical gloves, but the surgical gloves are very thin so as not to impair the user's delicate hand feeling, so the durability is weak, the holes are easy to open, and the tears are easy to tear. There are difficulties. If a burr remains on the edge of the cylindrical portion 22 of the lid member 20, if the surgical glove comes into contact with the burr, there is a risk that the surgical glove may be pierced or torn.

  In the disinfectant solution applicator 1, since the main body member 10 has the contact preventing portion 12, the user wears the main body member 10 while the user is gripping and using it. It is suppressed that a glove contacts the edge of the lid member 20.

  Moreover, since the disinfecting liquid applicator 1 can be used by being filled with various disinfecting liquids, it is excellent in versatility.

  Further, the disinfectant application device 1 has a simple configuration with a small number of parts and can be manufactured at a low cost, so that it can be provided at a low cost.

  In addition, although the example in which the pump unit 14 is formed flat on the side surface of the main body member 10 has been described, it may be formed on the bottom surface of the main body member 10 as shown in FIG. The pump portion 14 may be flat, but as shown in FIG. 9, the pump portion 14 may be formed to be curved in a convex shape toward the outside of the main body member 10. In this case, when the main body member 10 is filled with the disinfectant liquid, the side surface of the main body member 10 may be formed so as to protrude from the pump portion 14 so that the main body member 10 can be placed on a stand or the like.

(Embodiment 2)
As shown in FIGS. 10 and 11, the disinfectant applying device 2 according to the second embodiment includes a sealing member 15. The lid member 20 includes a perforating member 26. About others, it is the same as that of Embodiment 1 mentioned above.

  The sealing member 15 is attached to the opening of the main body member 10 to seal the inside of the main body member 10 and prevent the disinfecting liquid filled in the main body member 10 from leaking out. The sealing member 15 is a material that can prevent the disinfecting liquid from leaking, such as an aluminum sheet or a resin sheet, and is made of a material that can be perforated by a perforating member 26 described later.

  The piercing member 26 functions to make a hole in the sealing member 15. The piercing member 26 is disposed so as to protrude from the surface on the opposite side of the bottom 21 of the lid member 20 to which the application member 30 is joined. Here, the piercing member 26 is disposed at the center portion of the bottom 21 of the lid member 20 and has a shape in which three triangular plate-like bodies are joined.

  As shown in FIG. 12, when the lid member 20 is fitted into the main body member 10, the perforating member 26 opens a hole in the sealing member 15. Thereby, the disinfectant filled in the main body member 10 flows to the application member 30 through the hole vacated in the sealing member 15 and the hole 24 in the bottom portion 21 of the lid member 20.

  The perforating member 26 is not limited to the above-described form as long as the disinfecting liquid can perforate the sealing member 15 so that the disinfecting liquid flows to the application member 30 through the hole 24 of the lid member 20. For example, as shown in FIG. 13, a cylindrical perforated member 26 protruding around the hole 24 in the bottom portion 21 of the lid member 20 and cut into a tapered shape may be used.
