[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is a compact and properly stored endoscope cover which is inserted into a body cavity and mainly covers the outer surface of an electronic endoscope for endoscopic observation of the body cavity. The present invention relates to a package for an endoscope insertion portion cover section.

[0002]

2. Description of the Related Art An endoscope for observing the inside of a body cavity plays a large role in discovering various diseases, treating affected parts, and the like. Since this endoscope is used by inserting its insertion portion into a body cavity, it is necessary to wash and sterilize the same endoscope before using it for another subject. However, sufficient cleaning and sterilization of the endoscope requires a lot of hand clearance and a long time, so that there have been many problems in the efficiency of using the endoscope in a medical site. Therefore, in recent years, an endoscope equipped with an air supply pipe, a water supply pipe, a suction pipe, a forceps channel, and the like necessary for endoscope observation, and a cover that is sufficiently sterilized is provided with only an optical element. It has been proposed to use it by attaching it to a computer. Since this cover is disposable, there is no need to consider the hygiene of the endoscope itself.

[0003] In order to use the above-mentioned endoscope cover in an appropriate state, sufficient consideration must be given to its storage and storage methods. To this end, as means proposed so far, for example, US Pat.
084 is disclosed. This relates to a method of packing the endoscope cover, and is a bag that can be stored with the cover being straightened by a holding portion having a diameter larger than the diameter of the endoscope cover.

[0004]

However, the conventional packing method described above has various disadvantages. That is, since the endoscope cover is configured by combining a long pipe and a plurality of tube members due to its configuration, at the time of storage, if the pipe is stored while maintaining the cross-sectional shape at the time of use, There is a problem that the package becomes large. In addition, since the endoscope cover is disposable in principle,
In a large hospital, a laboratory, or the like where many subjects are to be examined, it is necessary to prepare a large number of endoscope covers. Then, when the package is large, there is a problem that a large storage space is required even when the packages are stacked and stored.

SUMMARY OF THE INVENTION The present invention is proposed to solve the above-mentioned problem, and a package of an endoscope insertion portion cover portion capable of properly and compactly storing an endoscope insertion portion cover portion and realizing miniaturization of a package. The purpose is to provide.

[0006]

SUMMARY OF THE INVENTION The present invention comprises a base member and a cover member for covering the base member. The insertion member cover for covering the outer surface of the insertion portion of the endoscope is accommodated in the base member while being curved. And closing the base member with the lid member and storing the endoscope insertion section cover section when the endoscope is not in use, wherein at least the inner lumen of the lumen formed in the insertion section cover section is used. The endoscope insertion channel is narrowed, and is housed in a storage portion having a width smaller than a natural outer diameter of the insertion portion cover portion of the base member.

[0007]

As described above, of the lumen formed in the insertion portion cover portion, at least the endoscope insertion channel is stored in a narrowed state, so that the R of the curved portion, the groove for fixing the insertion portion cover portion, etc. Can be reduced in width. Therefore, the size of the package can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of an endoscope apparatus equipped with an endoscope cover with a channel (hereinafter abbreviated as a cover) according to a first embodiment of the present invention.
A peripheral device such as a video processor 3, a fluid control device 4, an endoscope cover extender with a channel (hereinafter simply referred to as an extender) 5, a monitor 6 and the like are housed therein. The light source device 2 is connected to an endoscope with a channel endoscope cover (hereinafter, simply referred to as a cover endoscope) 7. A signal output from an image pickup device (not shown) provided near the distal end of the insertion portion of the cover endoscope 7 is provided to the video processor 3.
Is connected.

The cover endoscope 7 is covered with a cover 9 for covering the cover endoscope 7. This cover 9
Is constituted by an insertion portion cover portion 10, an operation portion cover 11, and a universal cover 12. The cover 9 is provided via a cover holder 13 that holds the cover 9.
The insertion section cover 10 is attached to the cover endoscope 7. The dilator 5 is provided with an expansion tube 14.

FIG. 2 is a sectional view of the insertion portion cover.
An endoscope insertion channel 15 into which the insertion portion of the endoscope is inserted, a forceps channel 16, and an air / water supply conduit 17 are formed in the insertion portion cover. Further, a proximal suction tube 18 communicating with the forceps channel 16, an air supply tube 19 communicating with the air supply / water supply conduit 17, and a water supply tube 20 are connected to the insertion portion cover.
The hand-side suction tube 18, the air supply tube 19, and the water supply tube 20 are connected to a suction device, an air supply source, and a water supply source (not shown) via the fluid control device 4 as shown in FIG. I have.

On the hand side of the insertion portion cover portion, an endoscope operation portion fixing mouth portion 21 for fixing the insertion portion cover portion to an operation portion of an endoscope (not shown) is provided. I have. A treatment tool insertion port 22 branched from the forceps channel 16 of the insertion section cover 10 is formed integrally with the endoscope operation section fixing port 21. In this embodiment, the endoscope operating section fixing mouth 21 and the treatment instrument insertion opening 2
2 is made of resin instead of metal.

FIG. 3 is a perspective view showing a state in which a package 24 having a groove 23 for winding and fixing the insertion portion cover is opened. The package 24 has a base member 25 and a lid member 26, each of which is at least partially air permeable but impervious to bacteria.
It is formed of a polymer material or paper having a vent of 2 μm or less. The base member 25 and the cover member 26 are covered with a film-like member 27 having an air hole of 0.2 μm or less that allows gas to pass therethrough but does not allow bacteria to pass therethrough without any gap.

FIG. 4 is a partial cross-sectional view of the base member 25 and the lid member 26. As shown, the wall 25a of the groove 23 formed in the base member 25 and the groove 2 of the lid member 26 are formed.
A porous sheet 29 having air permeability is fixed to a concave portion 26a formed at a position corresponding to No. 3. Further, at least one of the base member 25 and the lid member 26 is provided with a vent hole so that outside air is guided to the porous sheet 29. Thereby, the sterilizing gas at the time of sterilization can reliably reach the insertion portion cover. In FIG. 4, vent holes 30 and 31 are respectively formed in both.

FIG. 5 shows a cross section of the insertion portion cover portion accommodated in the package. Among them, FIG.
(A) shows a state before being housed in a package, and is in a substantially perfect circle state, and the endoscope insertion channel 32 is shown.
The forceps channel 34 and the air supply / water supply conduit 35 surrounded by the thick portion 33 are also open. On the other hand, FIG. 5B shows a state in which the endoscope is inserted into a package, and the endoscope insertion channel 32 is in a stenosis state.

In this manner, after the insertion portion cover 10 is narrowed and each member is stored in the package 24, it is gas-sterilized and transported to the user. Usually, the packaged cover 9 is packaged in a cardboard or the like in a set of 10 pieces and conveyed. However, if contents such as the type and size of the cover 9 are displayed on the package 24 and the cardboard box, the user can be provided. Needless to say, it is convenient for the user. In addition,
When a plurality of packages 24 are put in a cardboard box, gas sterilization can be performed in that state.

As described above, according to this embodiment, when the insertion section cover 10 is stored in the package 24, the air in the endoscope insertion channel 32 of the insertion section cover 10 is evacuated by a known means. Alternatively, a pressing force is applied to the endoscope insertion channel 32 from the outside to make the endoscope insertion channel 32 narrow. By doing so, the insertion portion cover 10 can be wound while forming a small R, and can be fixed in the groove 23 of the base member 25. Therefore, the groove 23
May be formed with a minimum diameter and a minimum groove interval, so that the size of the package 24 can be reduced. In addition, when the insertion section cover 10 is actually used, the endoscope insertion channel 32 is used.
By inserting the endoscope into the stenosis, the stenosis state is restored to the open state, so that no problem occurs. Also,
If the forceps channel 34 and the like in addition to the endoscope insertion channel 32 are narrowed, the insertion portion cover 10 will be able to be stored more compactly.

Further, since the porous sheet 29 is fixed around the place where the insertion portion cover 10 is fixed, the insertion portion cover 10 does not directly contact the base member 25 and the cover member 26. Therefore, when performing gas sterilization through the ventilation hole 30 or the like, it is possible to prevent the insertion portion cover portion that does not come into contact with gas from being generated. Further, since at least a part of the base member 25 and the lid member 26 of the package 24 is formed of a polymer material or paper which has air permeability but does not allow bacteria to pass through,
It can be sterilized by gas sterilization, and sterilization efficiency is good. Further, since the base member 25 and the cover member 26 are covered without gaps by the film-like member 27 that allows gas to pass but does not allow bacteria to pass, gas sterilization is possible with the package 24 as it is, and the sterilization state can be maintained until the package 24 is opened. The cover 9 can be properly stored.

FIG. 6 shows a second embodiment of the present invention, in which parts corresponding to those of the first embodiment are denoted by the same reference numerals (the same applies to the following embodiments). In the present embodiment, the groove 36 for fixing the insertion portion cover is formed by the linear portion 36a and the R portion 36b.
When the insertion portion cover is fixed to 6b, the endoscope insertion channel is narrowed. Further, the base member 25 and the lid member 26 are formed of a material having an air hole as in the first embodiment, and these are also covered with a film-like member 27 having an air hole without any gap. Other configurations are substantially the same as those in the first embodiment.

When the insertion portion cover portion 10 is stored in the package 24 having the above-described configuration, the insertion portion cover portion 10 can be stored without bending the tip of the insertion portion cover portion. When the insertion portion is inserted, it can be smoothly inserted. For other effects,
This is the same as the embodiment.

FIG. 7 shows a third embodiment of the present invention, and is a perspective view showing a state in which the insertion portion cover 10 is fixed to the base member 37. FIG. In the present embodiment, unlike the first embodiment, the insertion member cover 10 is not provided with a groove for fixing the insertion portion cover 10 in the base member 36, and the pins 38 are erected along the fixing member cover 10 along the fixing path. I have. Also, the pin 38 is shown in FIG.
As shown in the enlarged side view shown in FIG. 7, the head portion 38a is thicker than the shaft portion 38b, and the insertion portion cover 10 is fixed so as to be pushed between the shaft portions 38b. Further, the base member 25 and the lid member 26 are formed of a material having an air hole as in the first embodiment, and these are also covered with a film-like member 27 having an air hole without any gap. Other configurations are substantially the same as those in the first embodiment.

Since the third embodiment is configured as described above, when the insertion portion cover 10 in a narrowed state is fixed to the base member 25 via the pin 38, the insertion portion cover 1
0 is wound while forming a small R to form a package 2
4 can be stored. Therefore, it is sufficient that the interval between the pins 38 is formed at the minimum interval, and the size of the package 24 can be reduced. Also, when performing gas sterilization, even if the lid member 26 does not have air permeability, the insertion portion cover 10
If the gas is supplied so as to fill the space between the lid member 26 and the base member 25, the gas can be supplied without any portion that cannot contact the gas. Other effects are substantially the same as those of the first embodiment.

[0022]

As described above, according to the present invention, when the insertion portion cover portion 10 is stored in the package 24 while being curved, at least the endoscope channel 32 of the insertion portion cover portion 10 is narrowed. The width of the storage section such as the fixing groove and the pin of the section 10 can be reduced, and the insertion section cover 1
0 can be stored in a small package. Therefore, the size of the package can be reduced. Further, since the storage portion is formed only on the base member and nothing is formed on the lid member, the structure is simplified. Further, in the embodiment in which a porous material having air permeability is used for at least a part of the package 24, gas sterilization is performed while the insertion section cover 10 is stored in the package 24, and the insertion section cover section is added to the package 24 after gas sterilization. 10
Work that requires contamination must be avoided.
