The operation control when the switch is pressed can be changed as appropriate.

(Composition of medical device storage)
-Sheath member-
As shown in FIG. 4, the sheath member 40 of the medical device storage body 10 has a bag shape with an open upper end, and a stretchable ring portion 41 is provided at the peripheral edge of the opening. The ring portion 41 has, for example, a circular cross section, but is not limited thereto. The sheath member 40 may be integrally formed with the main body portion and the ring portion 41, or may be a separate body, but will be described below assuming that the sheath member 40 is integrally formed. ..

The sheath member 40 is made of a flexible sheet-like material, and is made of rubber as an example. As the rubber, for example, natural rubber latex, synthetic rubber latex and the like can be used. The sheath member 40 is preferably a liquid impermeable material that does not allow liquid to permeate in order to prevent permeation of bacteria, viruses, and the like, and a rubber material is also suitable from this point of view. The thickness of the sheath member 40 is not particularly limited, but is, for example, about 0.01 mm to 0.5 mm. The material of the sheath member 40 may be transparent, or may be a transparent material that is not completely transparent but has light transmission and allows the device housed therein to be visually recognized.

The entire circumference of the ring portion 41 (in other words, the entire circumference of the opening of the sheath member 40) may be about 100 mm to 300 mm, or may be about 150 mm to 250 mm in one example. The length referred to here is intended to be in a state of natural length in which the ring portion 41 is not extended, but is not necessarily limited to these specific dimensions.

The length of the sheath member 40 (the length from the ring portion 41 to the bottom) may be about 500 mm or less, more specifically 400 mm or less, although it depends on the size of the stored hand switch. May be good. The length of the sheath member 40 is also preferably 100 mm or more, and more specifically, 200 mm or more. This is because such a size is suitable for storing something like the hand switch 70 of the present embodiment that is gripped and operated by hand.

In this example, the bottom of the sheath member 40 is formed in a substantially hemispherical shape (a shape in which the bottom is substantially semicircular when the bag is folded flat). As a result, the sheath member 40 has a cylindrical shape as a whole, and the bottom has a substantially hemispherical shape. In other words, the sheath member 40 is formed in a seamless three-dimensional bag shape without a joint portion in which the members are joined to each other.

As another example, a flat bag-shaped sheath member formed by intermittently heat-sealing a tubular web sheet (made of a resin film in one example) may be used. In the above example, the sheath member 40 has a straight shape having a constant inner diameter, but in addition, for example, the inner diameters of the vicinity of the opening of the sheath member 40 and the vicinity of the middle abdomen are different (the diameter near the middle abdomen is larger). A sheath member having such a shape may be used.

-Guide case-
As shown in FIGS. 1 and 2, the guide case 20 is folded substantially flat in the state before use (referred to as “first form”), and when used, when it is grasped by hand and pressed on both sides, the guide case 20 is folded. It is designed to open.

As shown in FIG. 2 (open state, referred to as "second form"), the guide case 20 has a front surface 22, a rear surface 23, side surfaces 24 and 25 on both sides thereof, and openings 26 at the upper and lower ends. The outer frame 21 having 27 is provided. The ring portion 41 of the sheath member 40 may be directly attached to the vicinity of the opening 27 at the lower end of the outer frame 21, but in the present embodiment, as shown schematically in FIG. 5, the inner frame 28 is provided there. Has adopted a structure for holding the ring member 41.

The inner frame 28 is one size smaller than the outer frame 21, and is provided inside the outer frame 21. The inner frame 28 and the outer frame 21 are connected by a connecting body 31. Specifically, the connecting body 31 is formed so as to connect the lower end edge of the outer frame 21 and the upper end edge of the inner frame 28.

The guide case 20 having such a structure can be manufactured from one sheet-shaped member. Hereinafter, description will be made with reference to the development view of FIG. Note that FIG. 6 does not include numerical values such as dimensions and angles, but is a diagram shown to the extent that an actual medical device storage body can be manufactured based on these values. Therefore, the shapes (straight lines, curves, tapered shapes, ratios, etc.) shown in the drawings are matters disclosed by this application to the extent that those skilled in the art can understand.

The material of the guide case 20 is not particularly limited, and paper, a resin sheet material, or the like can be used.

As shown in FIG. 6, this developed view includes a front surface 22, a rear surface 23, and side surfaces 24, 25 constituting the outer frame 21. The rear surface 23 is composed of two parts 23-1 and 23-2. Further, the developed view of FIG. 6 includes a front surface 28-1 and rear surfaces 28-2 and 28-3 constituting the inner frame 28, and the front surface 22 of the outer frame 21 and the front surface 28-1 of the inner frame 28 are strip-shaped. It is connected by the connection part 31.

(Outer frame)
Both sides of the front surface 22 are ridge lines 22L and 22R that are inclined so as to be narrowed from the upper side to the lower side. The ridges 22L and 22R are mountain-folded lines. With such a configuration, when assembled, the outer frame has a tapered shape in which the upper end opening side expands. Auxiliary ridges 22b and 23b that are three-dimensionally bent so as to be folded at the time of use are provided on both sides of the respective ridges 22L and 22R. As an example, the auxiliary ridges 22b and 23b may be pre-embossed so as to be easily bent.

The front surface 22 and the rear surface 23 may have the same shape, but in the present embodiment, the heights of the front surface 22 and the rear surface 23 are such that the hand switch 70 can be easily inserted from the opening 26 (see also FIG. 2) during use. Are formed so that they are different. Specifically, a raised portion 23a is formed on the rear surface 23, and a concave portion 22a is formed on the front surface 22.

The portion of the rear surface 23-1 indicated by reference numeral 23h is a portion that overlaps and is adhered to a part of the other rear surface 23-2. Adhesion is not particularly limited, but may be by double-sided tape or by an adhesive such as glue. The portion indicated by reference numeral 23h may be adhered to a part of the rear surface 23-2 as a so-called “glue”.

(The inner frame)
Similar to the outer frame 21, both sides of the front surface 28-1 are ridge lines 28L and 28R that are inclined so as to be squeezed from the upper side to the lower side. The ridges 28L and 28R are mountain-folded lines. An opening is provided on the ridges 28L and 28R so that the notch 29 is formed when folded back.

As will be described later, this notch 29 is a place for hooking the ring portion 41 of the sheath member 40. The notch 29 is, for example, a concave portion having a V-shaped shape, a semi-circular shape, a U-shaped shape, or the like.

The portion of the rear surface 28-2 indicated by reference numeral 28h is a portion that overlaps and is adhered to a part of the other rear surface 28-3. Adhesion is not particularly limited, but may be by double-sided tape or by an adhesive such as glue. Similar to the above, the portion indicated by reference numeral 28h may be adhered to a part of the rear surface 28-2 as a so-called “glue”.

The connecting portion 31 is folded inside the outer frame 21 and acts like an arm for holding the inner frame 28.

(Assembly and usage)
Subsequently, assembling and usage will be described with reference to FIGS. 7, 8 and the like. First, the rear surfaces 28-2 and 28-3 of the inner frame 28 are adhered to form a frame shape (in this state, the flat state is formed), and then the connecting portion 31 is woven inside the outer frame 21. Although not limited, one side of the connecting portion 31 may be fixed to the inner surface of the outer frame 21, and this fixing may be performed by using a fixing means such as double-sided tape or glue. You may go there.

In this state, notches 29 are formed on both sides of the inner frame 28 as shown in FIG. 7, and then the ring portion 41 of the sheath member 40 is hooked at the notches 29 in a slightly extended state. As a result, the ring portion 41 is removably held by the inner frame 28 in a state where tension is applied.

Then, the sheath member 40 is folded and housed in the inner frame 28, and then the rear surfaces 23-1 and 23-2 of the outer frame 21 are adhered to complete the assembly (in this state, the whole is in a substantially flat state). Yes). The sheath member 40 may be housed in the inner frame 28 after the outer frame 21 is formed.

The medical device storage body 10 thus created is housed and enclosed in an outer bag (not shown). It is also preferable that the sheath member 40 alone or the assembly of the sheath member 40 and the guide case 20 is sterilized.

When using it, the procedure is as follows. FIG. 8A is a schematic view of the outer frame 21 and the inner frame 28 as viewed from the upper surface side.

First, the user opens the outer bag (not shown) and takes out the medical device storage body 10 from the bag. In this state, as shown in FIG. 1, the sheath member 40 is housed in the guide case 20, and is in the first form of being folded substantially flat. According to the configuration in which the sheath member 40 is housed in the guide case 20 in this way, it is possible to reduce the size of the product in the state before use (distribution state), and the sheath member 40 is protected by the guide case 20. Therefore, it is preferable from the viewpoint of preventing damage.

The user then grips the guide case 20 with one hand (example) and presses both sides inward (see also FIGS. 8 (a) and 8 (b)).

Then, the ridges 22L and 22R on both sides of the outer frame 21 are deformed so as to approach each other, and the frame gradually opens. At this time, the auxiliary ridges 22b and 23b on both sides of the ridges 22L and 22R are gradually bent so as to form a mountain fold, and as a result, the side surface of the guide case 20 is formed.

As the outer frame 21 is gradually opened, the ridges 22L and 22R on both sides approach each other, and then the inner frame 28 is also pushed inward from both sides and gradually opens (see FIG. 8B). Since the ring member 41 of the sheath member 40 is held on the lower end side of the inner frame 28, when the inner frame 28 is opened, the sheath member 40 is also opened at the same time.

According to such a configuration, the user can open the sheath member 40 by a simple operation of gripping the guide case 20, and can perform the work without touching the sheath member 40 at all. It is hygienic.

After the sheath member 40 is opened in this way, the user then inserts the hand switch 70 into the sheath member 40. Although not limited, it is also preferable that the sheath member 40 inside is lowered by its own weight and hangs down from the guide case 20 when the guide case 20 is opened. In such a configuration, the work of picking and pulling out the sheath member 40 and extending the sheath member 40 while inserting the hand switch 70 becomes unnecessary, which is preferable in terms of workability and / or hygiene.

Then, when the entire hand switch 70 is inside the sheath member 40, the user pulls the sheath member 40 and removes it from the guide case 20.

Then, as shown in FIG. 9, as an example, the mouth of the sheath member 40 is closed by using the clip 60. The clip 60 may have any shape, but in this example, the sheath member 40 is formed of a substantially U-shaped flexible member 61, and both ends thereof are engaged with each other. It may be something that can close the mouth. For example, substantially spherical end portions 63 may be provided at both ends.

Through the above series of steps, the hand switch 70 can be enclosed in the sheath member 40, and the user can use the hand switch 70 protected by the sheath member 40 in a clean state during the inspection.

After the inspection is completed, the sheath member 40 is removed from the hand switch 70 and discarded. When the hand switch 70 is used again for another patient, another medical device enclosure 10 is used.

As described above, the medical device storage body 10 of the present embodiment includes a guide case 20 and a sheath member 40, and the sheath member 40 is removably held by an inner frame 28 of the guide case 20 to guide the guide. The sheath member is opened at the same time as the case 20 is opened. Therefore, since the sheath member 40 can be opened only by opening the guide case 20 and the sheath member 40 is not touched, the hand switch 70 can be sealed with a simple operation and is hygienic.

As long as the sheath member 40 is configured so that the guide case 20 is disengaged when pulled, the mounting method of the sheath member 40 is not necessarily limited to the configuration in which the ring member 41 is hooked as in the present embodiment. For example, it may be fixed to a part of the guide case 20 with an adhesive, tape, or the like. However, according to the configuration in which the ring member 41 is hooked on the guide case 20 by using the elasticity (tension) as in the present embodiment, the work of applying an adhesive or affixing a tape becomes unnecessary, and the medical device Assembling of the housing 10 becomes easy.

Although one embodiment of the present invention has been specifically described above with reference to the drawings, the following changes may be made:
1. 1. Guide case (a) In the above embodiment, the double frame configuration has an outer frame and an inner frame, but as long as the sheath member is opened at the same time when the frame is opened from a substantially flat state, the sheath member is also opened. Only one frame may be used.
(B) In the above embodiment, the side surface 24 and the side surface 25 are formed by bending the auxiliary ridge lines 22b and 23b, but as a simpler configuration, such side surfaces 24 and 25 are formed. Instead, the guide case may be opened. As an example, the cylinder may be configured to be three-dimensional when both sides are turned inward from a state in which the cylinder is crushed and flattened.
(C) Forming the inner frame, the outer frame, and the connecting portion from one sheet-shaped member is preferable in one form from the viewpoint of ease of production and simplification of the configuration, but the present invention is not necessarily limited to this. It is not something that will be done. The inner frame and the outer frame may be configured as separate members, and in this case, the connecting portion may be omitted.

2. 2. Sheath member (a) In the above embodiment, the ring member 41 is provided at the opening, but the sheath member (a) may be attached to the frame by utilizing the elasticity of the main body without providing such a member. good.
(B) Sterilization of the sheath member can be carried out by various conventionally known methods, but for example, a sterility method by gamma ray irradiation may be used. Not only the sheath member but also the guide case may be sterilized, and this treatment may sterilize the sheath member and the guide case at the same time, or may sterilize them individually. Further, if there are other accessories, packaging bags, etc., they may also be sterilized.
