In the following description, the upper side in FIGS. 5 and 6 is referred to as a “proximal end”, and the lower side is referred to as a “distal end”.

The kit 1 for epidural anesthesia shown in FIGS. 1 and 2 includes forceps 2, a plurality of cotton balls 3, a plurality of cups 4 as a plurality of treatment tools used for epidural anesthesia. Epidural needle 5, epidural catheter 6, connector 7, filter 8, low friction syringe 9, multiple gauze 10, dressing 11, tape 12, multiple syringe 13
, A plurality of injection needles 14, a first small tray 100, a second small tray 200, a large tray (container) 300 for storing all of them, a drape 15, a sheet 16, Material 17. In FIG. 1, the packaging material 17 is omitted. Hereinafter, each component will be described.

The large tray 300 has an upper opening 3
10 and has a substantially rectangular parallelepiped storage space 32 therein.
0 is formed. In this storage space 320, FIG.
(Hereinafter, referred to as “before use”), the treatment tool, the first small tray 100 and the second small tray 20.
0 is stored.

The large tray 300 can also be used as a container for discarding the used treatment tool, for example, when performing epidural anesthesia. Thus, the waste can be collected, so that the dissipation of the waste can be more reliably prevented.

Large tray 300, first small tray 1 described later
The constituent materials of 00 and the second small tray 200 are, for example, paper, polyvinyl chloride, polyethylene,
Polypropylene such as polypropylene, polystyrene, poly- (4-methylpentene-1), polycarbonate, acrylic resin, acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate, butadiene-
Various resins such as styrene copolymers and polyamides may be mentioned, but paper is preferable from the viewpoint of easy disposal.

In the large tray 300, a second small tray 200 slightly smaller than the size of the storage space 320 is stored.

The second small tray 200 has a flange 210 projecting outward so as to surround the upper opening edge. The interior of the second small tray 200 has a storage space 231 formed by a partitioning part 220 having a substantially T-shape in plan view.

It is divided into two substantially rectangular parallelepiped spaces (parts).

By providing this partition 220,
The strength of the second small tray 200 can be further improved. In addition, the partitioning part 220 also has a function as a movement restricting unit that prevents each treatment tool stored in the second small tray 200 and the first small tray 100 from freely moving.

A plurality of (three in this embodiment) cups 4 are stored in the storage space 231 in a stacked manner.
A plurality (three in the present embodiment) of cotton balls 3 are stored in the uppermost cup 4.

Each cotton ball 3 and each cup 4 are punctured by an epidural needle 5 (for example, a patient's waist), for example, as described below.
This is used, for example, when performing an operation of disinfecting the surface (skin) of the puncture site prior to puncturing.

When disinfecting the surface of the puncture site by the epidural needle 5, an antiseptic solution is stored in the cup 4. And cotton ball 3
The cotton ball 3 is pressed against the puncture site and its surroundings to apply the disinfectant. This operation is performed by picking the cotton ball 3 with the forceps 2 described later.

The cup 4 is made of, for example, polyvinyl chloride, polyethylene, polypropylene, polystyrene, poly- (4-methylpentene-1), polycarbonate,
It is composed of various resins such as acrylic resin, acrylonitrile-butadiene-styrene copolymer, polyester such as polyethylene terephthalate, butadiene-styrene copolymer, and polyamide, and is preferably substantially transparent.

Further, the bottom of each cup 4 may be constituted by a tapered surface inclined toward, for example, one corner or the center. Accordingly, for example, when an operation of sucking the disinfectant stored in the cup 4 with a syringe 13 or the like described later is performed, this operation can be performed more efficiently.

In the illustrated configuration, the cups 4 have substantially the same shape, but the shapes of the cups 4 may be different. However, even in this case, each cup 4
Overlap is allowed. Thus, for example, when different types of disinfecting solutions are stored in the cups 4 and used, for example, the type of disinfecting solution in the cup 4 can be visually recognized, which is convenient.

From such a viewpoint, each cup 4
May be provided with a different marker (for example, coloring).

A storage space 232 is formed adjacent to the storage space 231 on the near side in FIG.

In the storage space 232, a plurality of (three in this embodiment) syringes (syringes with locks) 13 are provided.
And a plurality (three in this embodiment) of injection needles 14 are housed.

Each syringe 13 is used, for example, in the operation of sucking the disinfectant as described above, or in the operation of injecting the anesthetic under the surface of the puncture site (subcutaneous) or into the epidural space. Can be

Each injection needle 14 can be detachably attached to the tip of each syringe 13 by screwing.
An injection needle 14 is attached to the distal end of the syringe 13 to suck (collect) an anesthetic or the like into the syringe 13 from a container such as a vial or an ampoule, or a puncture site by the epidural needle 5 described later and the like. Local anesthesia (surface anesthesia) can be given to the surroundings.

Such a syringe 13 and injection needle 14
May all be of the same size,
Different sizes may be included.

In the storage space 232, a needle stand 221 having an increased number of partitions 220 is formed inside. The outer shape of the needle holder 221 is substantially a rectangular parallelepiped, and the inside thereof is hollow. Needle stand 2
On the upper surface of 21, there are formed three holes 222 which can hold the injection needles 14 in an upright state.

Each of the injection needles 14 is inserted into these holes 222 and is set up on the needle holder 221, for example.
This is convenient because the size of each injection needle 14 and whether or not each injection needle 14 has been used can be easily and reliably determined.

In this embodiment, the number of holes 222 is
Although provided according to the number of injection needles 14, it is not limited to this and can be set as appropriate.

Needless to say, the installation position of the needle holder 221 is not limited to the illustrated position.

A storage space 233, which is larger than these storage spaces, is formed adjacent to the storage spaces 231 and 232 on the right side in FIG.

The first small tray 100, the plurality of gauze 10, the dressing 11, and the tape 12 are stored in the storage space 233.

The first small tray 100 has a flange 110 projecting outward so as to surround the upper opening edge.
The first small tray 100 has a substantially rectangular parallelepiped storage space 120 formed therein.

When the first small tray 100 is set in the storage space 233, the flange 110 is engaged with the flange 210 of the second small tray 200 and the top of the partition 220, and the first small tray 100 The vertical position with respect to the two small trays 200 is defined.

As shown in FIGS. 3 and 4, the first
The width (length W1 in FIGS. 3 and 4) of the small tray 100 is
The width is set smaller than the width of the storage space 233 (the length W2 in FIGS. 3 and 4). Therefore, the first small tray 10
0 is set in the storage space 233, the first small tray 1
FIG. 3 and FIG.
A gap S1 is formed in the middle-lateral direction.

The gap S1 accommodates a tape 12 used for fixing the epidural catheter 6 to a patient, for example.

As shown in FIG. 4, the first small tray 1
The height of 00 (the length H1 in FIG. 4) is set smaller than the depth of the storage space 233 (the length H2 in FIG. 4). Therefore, when the first small tray 100 is installed in the storage space 233, the gap S2 is provided between the lower surface of the bottom of the first small tray 100 and the upper surface of the bottom of the storage space 233 (second small tray 200). Is formed.

In the gap S2, a plurality of gauze 10 and dressing 11 are stacked and stored. Each gauze 10 is used, for example, for wiping off excess disinfectant applied to the patient's skin and blood bleeding from the puncture site accompanying the puncture of the epidural needle 5 described later, and together with the dressing 11, which will be described later. It can be used for fixing the epidural catheter 6 to a patient.

In FIGS. 3 and 4, only the first small tray 100 and the second small tray 200 are shown, and other components are omitted.

Now, the storage space 12 of the first small tray 100
In 0, the epidural needle 5, the epidural catheter 6, the connector 7, the filter 8, and the low-friction syringe 9 are housed collectively.

The epidural catheter 6 is used for injecting (introducing) an anesthetic into the epidural space of the patient. The tip of the epidural catheter 6 is inserted into the epidural space of the patient. At its base end, a connector 7 enabling connection with the distal end of the syringe 13 and the filter 8 and a filter 8 used for removing foreign matter (for example, glass fragments generated when the ampule is opened) are connected (connected). Through these, the anesthetic is injected into the patient's epidural space.

The epidural needle 5 and the low-friction syringe 9
Is used for the operation of inserting the epidural catheter 6 into the epidural space of the patient.

As shown in FIG. 5, the epidural needle 5 has a needle 51 and a core 52 that can be inserted into and withdrawn from the needle 51.

The needle 51 has a hollow needle body 511 having a distal end opening 512 at the distal end, and a hub 5 fixed to the proximal end.
13 are provided. The tip of a low friction syringe 9 described later can be connected to the hub 513.

On the other hand, the core 52 has a solid, rod-shaped core main body 521 and a hub 522 fixed to the base end of the core main body 521. The core material body 521 has a size (length, thickness) and shape substantially corresponding to the hollow portion of the needle body 511. Therefore, the core material body 52
When 1 is loaded into the needle main body 511, the distal end opening 512 and the hollow portion of the needle main body 511 are closed by the core material main body 521.

The low-friction syringe 9 is provided with a needle 51 of the epidural needle 5.
Is a syringe for confirming the epidural space used to confirm that the distal end portion has reached the epidural space. As shown in FIG. A gasket 92 and a plunger 93 for moving the gasket 92 are provided.

The gasket 92 is formed of a member having a substantially columnar outer shape, and has an elastically deformable skirt portion 921 whose outer diameter gradually increases toward the distal end on its distal end outer peripheral portion. Also, on the outer peripheral portion of the base end portion of the gasket 92,
When the gasket 92 is inserted into the outer cylinder 91, a ring-shaped convex portion (positioning portion) 922 for more reliably preventing a deviation between the central axis of the gasket 92 and the central axis of the outer cylinder 91.
Are formed.

When this gasket 92 is inserted into the outer cylinder 91, the outer surface of the distal end of the skirt 921 and the convex 92
The vicinity of the top of 2 respectively contacts the inner surface of the outer cylinder 91. Thereby, gasket 92 (low friction syringe 9)
Exhibits excellent slidability that can move in the axial direction (longitudinal direction) of the outer cylinder 91 with a small force acting due to an increase and decrease in the internal pressure of the syringe, and excellent adhesion (particularly, airtightness). .

Such an epidural needle 5, epidural catheter 6, connector 7, filter 8, and low friction syringe 9
Is used as follows.

First, the epidural needle 5 is punctured into the waist (puncture site) of the patient with the needle 51 and the core 52 assembled.

Next, when the epidural needle 5 is punctured for a predetermined length, the core 52 is pulled out from the needle 51.

Next, the low-friction syringe 9 containing a predetermined amount of air is mounted on the hub 513 of the needle 51. And
When the needle 51 is further advanced, the distal end opening 512 of the needle 51 is opened.
Leads to the patient's epidural space. At this time, since the epidural space has a negative pressure, the air in the low-friction syringe 9 flows out to the epidural space and the volume in the low-friction syringe 9 decreases (toward the tip). Gasket 92 and plunger 93
Moves. Thereby, it can be confirmed that the distal end opening 512 of the needle 51 has reached the epidural space.

Next, the low-friction syringe 9 is removed from the needle 51, the epidural catheter 6 is inserted through the proximal end of the needle 51, and the distal end is inserted into the epidural space of the patient.

Next, the needle 51 is withdrawn from the patient, and subsequently withdrawn from the proximal end of the epidural catheter 6 and removed.

Next, the connector 7 and the filter 8 are attached to the proximal end of the epidural catheter 6 in this order.
Then, the distal end of the syringe 13 containing the anesthetic is connected to the filter 8 to inject the anesthetic.

At this time, the portion of the epidural catheter 6 that is exposed from the patient to the outside is fixed to the patient's back using the gauze 10, the dressing 11 and the tape 12. Thereby, it is possible to more reliably prevent the epidural catheter 6 from unintentionally falling out of the patient.

As described above, the cotton ball 3 is pinched on the upper part of the large tray 300 containing the treatment tools 2 to 14, the first small tray 100 and the second small tray 200 to disinfect the puncture site and its surroundings. A forceps 2 used for performing an operation or the like is stored. Note that tweezers may be stored instead of the forceps 2.

Further, a large tray 30 is placed above the forceps 2.
The drape 15 is folded and installed so as to cover the upper opening 310 of the “0”. The drape 15 is to be put on the patient before the epidural anesthesia is performed.

Hereinafter, an assembly of the treatment tools 2 to 14, the first small tray 100, the second small tray 200, the large tray 300, the forceps 2 and the drape 15 will be referred to as a "kit body 1 '".
Say

The kit body 1 ′ is entirely wrapped in a single sheet 16 before use, and furthermore,
It is hermetically stored in the packaging material 17.

As shown in FIG. 2, the wrapping material 17 is formed by stacking a pair of sheet materials 17a and 17b facing each other and fusing their outer peripheral portions (heat fusion, high frequency fusion, ultrasonic fusion, etc.) or Sealed by adhesion (adhesion with an adhesive or a solvent). The sheet 1 is placed in a space surrounded by the seal portion 171.
The kit body 1 'packaged in 6 is stored.

Also, as shown in FIG.
A part of the seal part 171 is another part (the seal part 172).
A weak seal portion (easy peel seal portion) 173 having a lower joining strength (peeling strength) is configured. Seal part 1
Reference numeral 72 denotes a state in which the opposing sheet materials are completely fused and in a strong bonding state, whereas the weak seal portion 173 is fused at a lower temperature and the like, so that the opposing sheet materials are fused. The state is considered to be somewhat incomplete. However, airtightness is also secured in the weak seal portion 173. And the effect lasts over time.

That is, in the packaging material 17, the weak seal portion 17
3, an opening for opening the packaging material 17 is formed.

The packaging material 17 and the sheet 16 include:
Preferably, a material having gas permeability and heat resistance capable of coping with sterilization of ethylene oxide gas, autoclave, radiation, electron beam, or the like, or a material capable of maintaining sterility after sterilization is used.

From such a viewpoint, the sheet material 17a,
Each of the sheet 17b and the sheet 16 is a single-layer film such as a polyolefin resin such as polyethylene and polypropylene, a blend resin of these polyolefin resins, a polyester resin such as polyethylene terephthalate, polyvinylidene chloride, and a vinyl chloride-vinylidene chloride copolymer. A film obtained by depositing aluminum, silica, or the like on these films, a metal foil such as an aluminum film or an aluminum laminated film, or a film containing a metal foil can be used. Further, a film obtained by laminating two or more of these films can also be used. Further, the sheet materials 17a and 17b and the sheet 16 may be made of, for example, a plastic nonwoven fabric or paper.

Thus, in such an epidural anesthesia kit 1, the interior of the packaging material 17 can be sterilized in advance, and the sterility inside the packaging material 17 is securely maintained until the packaging material 17 is opened. You.

It is preferable that at least one of the sheet materials 17a and 17b is substantially transparent in order to secure the visibility of the inside.

The thickness of the sheet material (single-layer or multilayer laminate) and the sheet 16 constituting such a packaging material 17 is as follows.
Each is appropriately determined according to the layer configuration and the properties of the material to be used (flexibility, strength, water vapor permeability, heat resistance, and the like), and is not particularly limited, but is usually preferably about 60 to 700 μm, More preferably, it is about 100 to 500 μm.

Further, since the sheet 16 is also sterilized in advance, the sheet 16 is developed and used at the time of epidural anesthesia, so that the sheet 16 can be used at a place of use (for example, an operating room). The clean area (the part of the sheet 16) and the unclean area (the part other than the sheet 16) can be clearly distinguished, which is convenient.

Further, in such an epidural anesthesia kit 1, the drape 15, which is necessary at the beginning of the epidural anesthesia operation,
The forceps 2, the cotton ball 3, the cup 4, and the like are installed on the upper part. Further, the treatment tools used at almost the same time are collectively stored in the first small tray 100 and the second small tray 200. Therefore, this operation can be performed more quickly, easily, and reliably, and the usability is good.

Although the present invention has been described based on the preferred embodiment shown in the drawings, the present invention is not limited to this, and each part constituting the epidural anesthesia kit performs the same function. Any configuration that can be used can be substituted.

In the kit for epidural anesthesia of the present invention,
The treatment tools can be stored in any combination, and components other than those shown can be added.
