[0002]

2. Description of the Related Art Extracorporeal blood circulation circuits in hemodialysis, artificial lungs and the like are mainly composed of long medical instruments such as tubes, and are opened at the site (dialysis room, operating room, etc.) each time they are used. For example, it is used by attaching to a blood circulation device such as a roller pump or a centrifugal pump.

[0003] The tube is housed in a sealed container made of a material through which pathogenic bacteria do not pass, in order to circulate the blood of the patient, and is sterilized by high-pressure steam sterilization or ethylene oxide gas.

However, when such a tube is connected to a blood circulation device, the sealed container is opened and a blood extracorporeal circuit is connected and prepared. A state (dirty area) where there is a risk of sticking will result.

[0005] In particular, a blood access and insertion beak (referred to as a cannula or catheter) inserted directly into a patient's blood vessel.
In the vicinity of the end of the tube connected to the patient, that is, near the end of the tube placed on the operation field side, the surface directly touches the surgical wound of the patient or the hand of the surgeon, etc. May invade the body of the patient and cause serious infections and the like in patients.

For this reason, some tubes are packaged in a package such as an inner bag or a nonwoven fabric, and further housed in a sealed container. With such a configuration, even after opening the sealed container, the surface near the distal end of the tube arranged on the operation field side is not dirty. However, such a hermetically sealed container has a problem in that the operation of taking out the tube is complicated, and the visibility from the outside during the operation of filling the inside of the tube with the filling liquid to remove the bubbles.

[0007] In order to solve these problems, a medical device storage container including a transparent lid and a tray for storing tubes has been used.

However, the conventional medical device storage container also has the following problems.

[0009] The tray of the medical device storage container has a plate-shaped bottom portion and a wall portion surrounding the outer periphery standing upright from the bottom portion.
The tube is stored in contact with the bottom of the tray. For this reason, when removing the tube from the tray,
The surgeon must grasp the tube over the wall,
It may be difficult to perform this operation easily.

[0010] Further, a fixing member is used for the tray in order to fix the accommodated tube. This fixing member has a configuration in which a hole through which a tube can be inserted is provided at a substantially central portion thereof, and this hole and the outside of the fixing member are connected by a slit. The tube is inserted into the fixing member through the slit, and is fixed to the tray in this state. Therefore, when the tube is taken out of the tray, the tube is taken out of the tray while being inserted through the fixing member. For this reason, it is necessary to perform the operation of removing the fixing member from the tube again, and it is difficult to easily perform the operation of removing the tube from the tray.

Is shown. In the following description, the right front side in FIGS. 1 to 3 is referred to as “front” or “front”, and the left back side is referred to as “rear” or “rear”.

A medical instrument storage container 1 according to the present invention shown in FIGS. 1 to 3 comprises a tray 2 and a lid 3 placed on the tray 2.
And a holding member 5 detachably mounted on the tray 2
And Hereinafter, each component will be described.

The tray 2 accommodates, for example, a tube 4 which is a long medical device constituting a part of the extracorporeal blood circulation circuit. The tray 2 includes a plate-shaped bottom portion 22 and a wall portion 23 standing upright from the bottom portion 22 and surrounding the outer periphery. The storage space 21 is defined by the bottom 22 and the wall 23, and the tube 4 is stored in the storage space 21.

By the way, since the tube 4 is a portion directly connected to, for example, a blood vessel of a patient, the tube 4 must not adhere to a pathogen. For this reason, the medical device storage container 1 is sterilized in a state as shown in FIG. 1, that is, in a state where the tube 4 is stored in the tray 2 (storage space 21) and the lid 3 is covered. . The lid 3 is covered on the tray 2 until immediately before the tube 4 is connected to a blood vessel or the like of a patient. Therefore,
The portion of the tray 2 covered by the lid 3 is a portion (hereinafter, referred to as a “clean portion”) in which an aseptic state is maintained until the lid 3 is removed from the tray 2.

On the other hand, the ends 41a, 41b of the tube 4
An outer peripheral portion (a portion protruding outward from the wall portion 23) and a lower surface of the bottom portion 22 of the tray 2 connect the blood circulating apparatus and the tube 4 before connecting the tube 4 to, for example, a blood vessel of a patient. This is where the technician or the like touches his hand. Therefore, there is a possibility that the above-mentioned pathogenic bacteria may be attached to such a portion. Below, such a part,
That is, the portion of the tray 2 not covered by the lid 3 is
Say "the dirty part."

A bent portion 24 is formed on the front side of the bottom portion 22 in a direction substantially perpendicular to the longitudinal axis thereof (substantially up and down in FIG. 2). The bent portion 24 is a rotating portion that can rotate the front side of the tray 2 and expose a part of the tube 4 stored in the storage space 21 to the outside of the storage space 21.

In the case of the medical device storage container 1 not provided with the bent portion 24, the unclean portion is protruded toward the operator when the tube 4 is connected to a blood vessel or the like of a patient. . For this reason, for example, the hands of the surgeon may come into contact with the unclean area, and the pathogenic bacteria may adhere. If this is noticed, hand washing, replacement of gloves, and the like are performed again. However, if surgery is performed without noticing this, the patient may be invaded (infected) by pathogenic bacteria, leading to serious infectious diseases and the like. In addition, such a medical device storage container 1
In this case, the outer peripheral wall of the tray 2 becomes an obstacle, and it is difficult to easily take out the tube 4.

On the other hand, the medical device storage container 1 of the present invention
In the operation for connecting the tube 4 to a blood vessel or the like of a patient, the front side of the tray 2 is rotated at the bent portion 24 as shown in FIG. And the inner surface of the wall 23 can be extended toward the operator. Therefore, it is possible to reliably prevent the operator's hand or the like from touching the unclean portion. Also,
In such a medical device storage container 1, since a part of the tube 4 is exposed from the storage space 21, the tube 4 can be easily taken out from the storage space 21, and the tube 4 is not erroneously grasped. .

The bending (rotation) angle is not particularly limited. For example, the angle θ shown in FIG. 3 is preferably 90 ° or more. Thereby, the unclean part (especially, bottom 2
2 can be kept away from the surgeon, so that the pathogens can be more reliably prevented from adhering to the surgeon's hands and the like.

A pair of holes 25, 25 are formed near the front end of the bottom 22, and a string (or belt) 26 is fixed to these holes 25, 25. This string 2
Reference numeral 6 denotes an operation member for rotating the bending portion 24.
When the string 26 is pulled downward and further rearward of the tray 2, the front side of the tray 2 rotates about the bent portion 24. At this time, a part of the tube 4 is exposed from the storage space 21. In addition, this operation can be performed by a person other than the surgeon (for example, a technician or the like) without touching the inner surface of the wall 23. Therefore, it is possible to more reliably prevent the pathogen from adhering to the storage space 21.

Further, such a string 26 can be used not only as an operating member, but also, for example, in a state shown in FIG.
The tray 2 with the lid 3 covered thereon can be used as a suspending tool for suspending, for example, a pole, a hanger, or the like provided in a blood circulation device.

The bottom 22 has a substantially central portion,
Four plate-shaped protrusions 27 are provided upright. These convex portions 27 are regulating members that regulate the movement of the tube 4 in the storage space 21. These projections 27 are locked inside the loop of the tube 4 housed in a loop shape, and fix the tube 4 in the storage space 21.

The configuration of the convex portion 27 is not limited to the illustrated one, and may be formed, for example, in a cylindrical or columnar shape. In the illustrated configuration, the protrusion 27 is formed only on the tray 2, but may not be formed on the tray 2 and may be formed only on the lid 3. Also, the protrusion 27
Is formed on both the tray 2 and the lid 3, and the tray 2
The configuration may be such that, when the lid 3 is placed on the cover, the opposing surfaces come into contact with each other.

The wall portion 23 is composed of a front surface 23a, two side surfaces 23b, 23b, and a rear surface 23c. These side surfaces 23b are respectively provided with cutouts 28, 28 near the both ends of the bent portion 24. Are formed. Thereby, the turning operation of the bent portion 24 can be performed more reliably.

9 are formed. Nipping members 5, 5, which will be described in detail later, are detachably installed in these notches 29, respectively.

The lid 3 is put on the tray 2. By covering the lid 3 on the tray 2 until immediately before the use of the tube 4, the inside of the storage space 21 (clean portion) can be more reliably prevented from adhering pathogenic bacteria.

The lid 3 has a plate-shaped covering portion 31 and a covering portion 3
1 and an outer peripheral wall 32 surrounding the outer periphery, and is preferably made of a transparent (colorless transparent or colored transparent) member in order to ensure the visibility inside.

The outer peripheral wall 32 is provided with the tray 2
Passing portions 33, 33 are formed at positions corresponding to the notches 29, 29, respectively, from the bottom to the top in FIG. When the tray 2 is covered with the lid 3, the tube 4
Is stored in the tray 2 so as to pass through a portion surrounded by the passage portion 33 and the cutout portion 29.

The constituent materials of the tray 2 and the lid 3 include, for example, polyethylene, polypropylene,
Polybutadiene, polyolefin such as ethylene-vinyl acetate copolymer, polyvinyl chloride, polyurethane, polystyrene, polymethyl methacrylate, polycarbonate, polyamide, polyester such as polyethylene terephthalate or polybutylene terephthalate, ABS resin, AS resin, ionomer, polyacetal, polyphenylene Various resin materials such as sulfide and polyetheretherketone are exemplified.

The tube 4 stored in the storage space 21
Is a part of the extracorporeal blood circulation circuit. The tube 4 is formed of a flexible tube.

The tube 4 is wound in a loop and
7 and is stored in the tray 2 such that its ends 41 a and 41 b are located outside the storage space 21. These end portions 41a and 41b are portions that a technician or the like grasps by hand or the like when connecting the tube 4 to the blood circulation apparatus.

The ends of these ends 41a and 41b are sealed by stoppers 42 and 42, respectively, and the lumen of the tube 4 is maintained in a sterile state.

The ends 41a and 41b are preferably provided with markers such as different color stickers to distinguish them from each other. Thereby, for example, a connection error with the blood circulation device can be more reliably avoided.

The holding member 5 holds a part of the tube 4 and seals the cutout portion 29 of the tray 2 and is made of a plate-shaped (band-shaped) elastic member.

On the other hand, as shown in FIG. 4, a groove 292 is formed in the notch 29 along the edge 291 thereof.

The notch 29 is sealed by its own elastic force, and the upper surfaces 51 thereof are in contact with each other to form a slit 52.

The tube 4 is inserted into the slit 52 and is held and fixed by the holding member 5 (see FIG. 6).
At this time, since the holding member 5 has an elastic force, the outer peripheral surface of the tube 4 and the inner surface of the slit 52, that is, the upper surface 5
1 is in close contact.

By providing such a holding member 5, the movement of the tube 4 in the storage space 21 can be more reliably prevented, and the adhesion of pathogenic bacteria to the storage space 21 (clean portion) can be further improved. It can be reliably prevented.

When the holding member 5 is configured as described above, for example, the operation of taking out the tube 4 from the storage space 21 can be performed more easily and smoothly as follows.

First, the tube 4 is placed on the tray 2 as shown in FIG.
When the tube 4 is pulled upward, the holding member 5 moves upward together with the tube 4 due to the frictional force between the outer peripheral surface of the tube 4 and the inner surface of the slit 52, disengaged from the groove 292, and detached from the tray 2. I do. At substantially the same time, the holding member 5 returns to substantially the original shape by its own elastic force, and releases the holding of the tube 4.

The constituent material of such a holding member 5 is, for example, natural rubber, butyl rubber, isoprene rubber,
Various rubber materials such as butadiene rubber, styrene-butadiene rubber and silicone rubber, and various thermoplastic elastomers such as polyurethane-based, polyester-based, polyamide-based, olefin-based, and styrene-based resins, and resin materials such as a mixture thereof. .

At this time, since the outer peripheral portion of the bottom portion 22, which is the unclean portion, on the front side of the bent portion 24, enters below the lower surface of the bottom portion 22 and is kept away from the surgeon, the hands of the surgeon are placed in the unclean portion. The pathogen can be more reliably prevented from being touched and adhered to the operator's hand or the like.

When the operator removes the tube 4 from the tray 2, the ends 41a and 41b of the tube 4 are pulled upward in FIG. At this time, the sandwiching member 5 causes the tray 2 (the groove 29) to move due to friction between the outer peripheral surface of the tube 4 and the inner surface of the slit 52.
At the same time, the V-shaped (or U-shaped) member is opened by its own elastic force, returns to the original shape, and the tube 4 is released.

[5] Next, the operator cuts the middle of the tube 4 and connects it to the blood vessels (arteries and veins) of the patient.
As a result, the patient and the blood circulation device are connected, and preparation for extracorporeal blood circulation is completed. Then, the blood circulation device is operated to start extracorporeal circulation of blood.
