Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a medical instrument storage case for storing medical instruments such as endoscopic treatment instruments.

Generally, medical instruments A for endoscopic treatment that are used repeatedly are gas sterilized using a sterilizing gas such as used ethylene oxide gas or formalin gas. The sterilized medical instruments are stored, for example, in a sealed storage case until the next time they are used, to prevent them from being contaminated by bacteria or the like.

By the way, gas sterilization is performed by bringing a sterilizing gas into contact with a medical instrument placed on a mounting plate, etc., and Ryo Seison transferred the sterilized medical instrument-X into a sealed storage case. The reality was that they had been replaced. Therefore, it was necessary to completely replace the medical instruments after sterilization, which was troublesome. In addition, although a large number of medical instruments are usually sterilized at the same time, the next use time of each medical instrument is often different, so it is recommended to transfer each medical instrument to a separate storage case and store it. I was doing it. Therefore, the task of transferring medical instruments has become even more troublesome.

In addition, in the past, a storage case for storing medical instruments had a through hole, and a porous sponge-like resin block tube was installed inside the hole, so that all medical equipment could be stored in the storage case. There was one that was able to be sterilized with gas. However, in this case, if the medical instruments were stored in the storage case used during sterilization after sterilization, there was a risk that #M fat might enter the storage case through the through holes in the storage case. Even in this case, it was necessary to transfer the medical instruments into another sealed storage case after sterilization.

This invention was made based on the above-mentioned circumstances, and its purpose is to be able to perform gas sterilization with medical instruments stored inside, and to eliminate the trouble of transferring medical instruments after sterilization, thereby simplifying the work. An object of the present invention is to provide a medical instrument storage case that can be easily stored.

The present invention will be described below based on embodiments shown in the drawings. 1 to 6 show a first embodiment of the present invention, and 1 is a case body. This case body 1 includes a holder 3 equipped with a groove-shaped medical instrument storage section 2f on the upper surface side,
The holder 3 is formed with a lid 5 hinged to an opening/closing member 14 on the upper surface of the holder 3 by hinge parts 4, 4. The medical instrument storage section 2 is for storing medical instruments 6 such as treatment instruments for endoscopes, and is formed in a shape corresponding to the shape of the medical instruments 6 to be stored. The holder 3 has a sealing material 7 protruding around the medical instrument storage section 2 on the upper surface thereof, and hooks 1s8, 8 and 1s on the opposite side to the section where the hinge sections 4, 4 are located. A handle 9 is provided. The lid body 5 also includes a tear gold recess 10 into which the sealing material 7 is fitted and a hook 11 which engages with the hook groove 8°8.
．． 11 are provided. Then, when the hooks 11 and 11 are engaged with the seven hook grooves 8°8 and the holder 3 is closed by the lid 5, the sealing material 7 of the holder 3 is fitted into the fitting recess 10 of the lid 5. The medical instrument storage section 2 of the holder 3 is hermetically sealed.

Furthermore, a communication hole 12 is provided in the lid body 5 at a portion facing the medical instrument storage section 2 . A receiving portion 12a is formed in a portion of the communication hole 12 adjacent to the medical instrument storage portion 2, which protrudes more inward than other portions. When the holder 3 is closed by the lid 5, the communication hole 12 allows communication between the medical instrument storage section 2 and the outside, and the communication hole 12 is closed by the sterilization sheet 13. There is. This sterilization sheet 13 is a mesh-like material that cannot pass sterilizing gas such as ethylene oxide gas or formalin gas, but cannot pass bacteria, and is a packaging material for sterilized medical instruments, a so-called sterilization material. Known examples include those made of paper and water-resistant ones molded from 4-lyethylene fibers (sunodandedde-olefin).

As shown in FIGS. 4 and 5 of this sterilization sheet 13Fi, the receiver of the communication hole 12 is fixed to the portion 12m under pressure by means of a presser frame 14 via an airtight seal 15. Note that a locking protrusion 12b for locking the presser frame 14 is formed near the outer end of the communication hole 12. This locking protrusion 12bFi is formed to have a slightly smaller diameter than the presser frame 14, and by pulling the tab 14 island f of the presser frame 14 outward, t'
(The presser frame 14 can be easily removed from the communication hole 12, and the sterilization sheet 13 can be replaced. Also, on the lower surface of the holder 3, there is a convex portion 16 for stacking... Recesses 17 for stacking are provided on the upper surface of the holder 3, and as shown in FIG.
are inserted into each recess 17 of the lid 5 of another case body 1 and stacked. In addition, the height dimension of each convex part 16... of the holding body 3 is larger than the depth dimension of each concave part 11... of the lid body 5.

Therefore, in the above structure, since the communication hole 12 is closed by the sterilization sheet 13, the holder 3 is sterilized with the lid 5 closed, as shown in FIGS. 3 and 4. Self-gas can be allowed to pass through the sterilization sheet 13 and enter the medical instrument storage section 2. Therefore, a gas sterilization session can be performed with the medical instruments 6t stored inside the case body 1. In addition, since the sterilization sheet 13 is impermeable to bacteria, the sterilization process also applies to the case body 1.
The medical instrument 6t can be stored with the medical instrument A6 housed inside.

Therefore, there is no need to transfer the medical instrument 6 after sterilization as in the conventional method, and the work can be simplified. moreover,
Since the height dimension of each convex part 16 for stacking the holding body 3 is larger than the depth dimension of each concave part 17 for stacking the lid body 5, multiple case bodies 1 ...When all the case bodies 1 are stacked, a gap can be reliably formed between each case body 1. Therefore, even when multiple case bodies 1... are stacked, each case body 1...
・Medical equipment x6 stored inside can be reliably sterilized. In addition, there is no need to transfer the sterilized medical instruments 6 to another sealed storage case.
There is no fear that the medical instrument A6 will be contaminated by particles when transferring the medical instrument 6.

Furthermore, since the medical instrument 6 can be moved to another location while being housed in the case body 1, the medical instrument 6 can also be easily moved.

Next, we will explain the second embodiment shown in Figs.
The case main body 22 is formed of a holder 24 having a spiral and groove-shaped medical instrument storage section 23 on the upper surface, and a lid 25 that is fitted onto the upper surface of the holder 24. The holding body 24fC is hermetically fitted. It is longer than the medical instrument 21 stored in the medical instrument storage section 23d and communicates with an insertion opening 26 formed on the side surface of the holder 24. A retaining portion 27 is formed in the vicinity, and
An opening/closing door 31 is attached which is rotatable around a rotation shaft 28 and has a hook 29 formed at its free end and a sealing material 30 affixed to its inner surface, and the hook 29 engages with the engaging portion 27. Then, the insertion port 26 is hermetically closed by the e@ pasted door 31.

Further, the lid body 25 is provided with a communication hole 32 that allows communication between the medical instrument storage section 23 and the outside, and this communication hole 32Vi is closed by a sterilization sheet 33 through which sterilization gas can pass but through which bacteria cannot pass. has been done. This sterile sheet 3
3#'i It is detachably attached to the communication hole 32 by a presser frame 34. Further, the holding body 24 is provided with a handle 35 and a convex portion 36 for stacking, and the lid body 25 is provided with a concave portion 37 for stacking Fi.

Even with this configuration, the communication hole 32 of the bag body 25 is closed by the sterilization sheet 33, so the medical instrument 21 is inserted into the medical instrument storage section 23 through the insertion port 26, and the opening/closing door 31 closes the insertion port 26. Medical instruments 2 stored in the medical instrument storage section 23 with sterilized gas in a closed state
1 can be sterilized. Furthermore, since there is no risk of bacteria entering the medical instrument storage section 23, there is no need to worry about transferring the medical instrument 21 to another sealed storage case after sterilization. In addition, in this embodiment, the opening/closing opening 31 is provided on the side surface of the holder 24, so that the case body 22 can be opened and closed as shown in FIG.
It is possible to take in and take out the medical instruments 21 in a stacked state.

Note that the present invention is not limited to the above embodiments. For example, as shown in FIG. 9, the case body 22 in the second embodiment may be stored in a rack 4. Further, the sterilization sheet may be configured to be fixed to the communication hole. Other various expenses may be made within the scope of the gist of the invention! Of course, it can be done.

As described above, the present invention provides a communication hole that allows communication between the medical device storage section and the outside in a sealed case body that stores medical instruments therein, and allows all sterilization gas to pass through the communication hole. This is a sign that the sterilization sheet is blocked by a sterile sheet that is impossible for bacteria to pass through. Therefore, all gas sterilization can be performed while the medical instruments are housed inside the case body, and there is no need to transfer the medical instruments after sterilization, making the work easier.
