Description

  The present invention relates to a medical tray on which a plurality of catheters each having a flexible catheter body and a hub installed at a proximal end portion of the catheter body are temporarily placed.

  When using a catheter having a flexible catheter body and a hub installed at the proximal end of the catheter body, the outer peripheral surface (outer surface) and inner peripheral surface of the catheter main body are, for example, physiological saline (liquid ) To use. In order to bring the catheter body into contact with the liquid, a method is known in which the catheter body is infiltrated into a medical tray filled with physiological saline (for example, see Patent Document 1).

  Each of the medical trays described in Patent Document 1 is configured by a substantially rectangular bottom plate and a wall portion standing along the edge of the bottom plate, and in a space defined by the bottom plate and the wall portion. Saline can be supplied. A plurality of notches (slits) are provided at the boundary between the four wall portions of the medical tray. The proximal end side of the catheter can be passed through each notch. In the medical tray of Patent Document 1, the notches are respectively disposed at the four corners of the wall.

  In such a conventional medical tray, when a plurality of catheters are placed by projecting the end portions of the catheters from the respective notches, these catheter bodies are placed from the notches to the center of the medical tray. Towards, it enters the space from different directions. For this reason, the problem that the catheter main bodies are intertwined has arisen. Further, when removing any one of the plurality of catheters, the catheters (catheter body) are intertwined with each other, so that the operation for removing the catheter has become troublesome. Further, when one arbitrary catheter is taken out, another catheter may be caught in the taken out catheter, and the other catheter may jump out (bounce off) from the medical tray.

JP 2004-89618 A

  The purpose of the present invention is to prevent entanglement between a plurality of placed catheters, and when taking out one of the plurality of catheters, the removal operation can be performed smoothly, It is an object of the present invention to provide a medical tray that can reliably prevent another catheter from being wound around the extracted catheter and preventing the other catheter from popping out.

In order to achieve the above object, the present invention provides a medical device for temporarily placing a plurality of catheters having a long flexible catheter body and a hub installed at the proximal end of the catheter body. A tray for
A tray body having a bottom plate and a wall portion standing along an edge of the bottom plate, and a storage space in which each catheter body is housed is defined by the bottom plate and the wall portion;
A plurality of support portions for supporting a proximal end portion of the catheter;
A plurality of the support portions are provided for one of the wall portions, and support angles of the proximal end portions of the catheter supported by the support portions with respect to the wall portions are different from each other. It is the medical tray characterized by being arrange | positioned.

  As a result, it is possible to prevent entanglement between a plurality of placed catheters, and when taking out one of the plurality of catheters, the take-out operation can be smoothly performed and taken out. It is possible to reliably prevent another catheter from being caught in the catheter and the other catheter from popping out.

  In the medical tray of the present invention, it is preferable that the respective catheter main bodies are regulated so as to form a loop by the wall portions when stored in the storage space.

  Accordingly, when the catheter is taken out from the tray, the taking-out operation can be performed easily and smoothly by pulling (pulling out) the catheter in a direction substantially equal to the tangential direction of the loop.

  In the medical tray of the present invention, it is preferable that each of the support portions is configured to support a proximal end portion of the catheter in a tangential direction of a loop of the catheter body.

  As a result, the loop of the catheter body is expanded to the maximum with respect to the tray bottom area, so that the radius of curvature of the catheter body becomes relatively large, suppressing the force to straighten the catheter, and reducing the adverse effects of deformation. Reduces the risk of jumping out and suppresses entanglement with other catheters.

  In the medical tray of the present invention, it is preferable to take out the catheter in a direction substantially equal to a tangential direction of a loop formed by the catheter body.

  As a result, the catheter can be easily and smoothly taken out.

Further, in the medical tray of the present invention, the tray body is a quadrangular shape in plan view,
Preferably, the plurality of support portions are provided on one side of the four sides of the tray body.

  As a result, the catheter can be easily and smoothly taken out.

Further, in the medical tray of the present invention, the tray body is a rectangular shape in plan view,
It is preferable that the plurality of support portions are provided concentrated on one of the two long sides of the rectangle.

  As a result, the catheter can be easily and smoothly taken out.

  In the medical tray of the present invention, it is preferable that the plurality of support angles are gradually reduced from one end side to the other end side of the one side.

  Thereby, the catheter supported by each support part can each easily and reliably form a loop in which the catheter body is wound in the same direction. Thereby, the entanglement of the catheter main bodies can be prevented.

  In the medical tray of the present invention, it is preferable that the interval between the adjacent support portions gradually increases from one end side to the other end side of the one side.

  Thereby, the interference of the parts by the side of the base end part of the catheter supported by each support part can be prevented.

  In the medical tray of the present invention, each of the support portions has a C-shape, a U-shape, or a shape in which an inner surface thereof is bent, each having a recess opening upward. It is preferable that the proximal end portion of the catheter is supported by being inserted into the recess.

  Thus, by pushing (inserting) the proximal end portion of the catheter from above, the concave portion is elastically deformed, and the proximal end portion of the catheter can be fitted. Thereby, a catheter can be supported reliably.

  In the medical tray of the present invention, it is preferable that the bottom surface of the concave portion is located at a position spaced above the upper end of the wall portion.

  As a result, the proximal end portion of the catheter can be supported as high as possible, so that the catheter can be easily taken out.

  In the medical tray of the present invention, it is preferable that the bottom surface of the concave portion is inclined so that the storage space side is at a low level.

  Since the proximal end portion of the catheter is supported by the support portion, a force that presses the catheter body against the bottom plate acts, and the catheter body can be prevented from unintentionally jumping out of the storage space. In addition, when the tray is filled with physiological saline, the catheter is easily immersed in the physiological saline.

  In the medical tray of the present invention, it is preferable that the catheter main body has a protrusion preventing means for preventing the catheter bodies from protruding from the storage space.

  Accordingly, when any one of the plurality of catheters is taken out, even if another catheter is caught in the taken-out catheter and the other catheter moves upward, the movement is restricted. The As a result, the caught catheter can be reliably prevented from jumping out of the storage space.

  In the medical tray of the present invention, it is preferable that the protrusion preventing means is constituted by a plate piece that is formed at the upper end portion of the wall portion so as to protrude toward the storage space.

  Accordingly, when any one of the plurality of catheters is taken out, even if another catheter is caught in the taken-out catheter and the other catheter moves upward, the movement is restricted. The As a result, the caught catheter can be reliably prevented from jumping out of the storage space.

Further, in the medical tray of the present invention, the storage space can store a long and flexible medical device different from each of the catheters,
Preferably, the bottom plate is formed with a protruding portion that restricts the medical device so as to form a loop when the medical device is stored in the storage space.

  When the medical device is stored in a looped form, when the medical device is taken out from the tray, it is easy to distinguish from each catheter, and the portion in contact with the restriction portion of the medical device By pulling upward along the protruding direction, the take-out operation can be performed easily and smoothly.

FIG. 3 is an enlarged detail view of a support portion of the medical tray shown in FIG. 4 is a cross-sectional view taken along line BB in FIG.

Hereinafter, the medical tray of the present invention will be described in detail based on a preferred embodiment shown in the accompanying drawings.
1 is a plan view showing a state where a catheter and a guide wire are placed on the medical tray of the present embodiment, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is shown in FIG. FIG. 4 is an enlarged detailed view of the support portion of the medical tray, and FIG. Hereinafter, for convenience of explanation, the upper side in FIGS. 2 to 4 is referred to as “upper” or “upper”, and the lower side is referred to as “lower” or “lower”. In FIG. 2, the catheter and the guide wire are omitted.

  A medical tray (hereinafter simply referred to as “tray”) 1 shown in FIG. 1 is supplied with physiological saline therein, and in that state, a plurality of (five in the illustrated configuration) catheters 11a and 11b. , 11c, 11d, and 11e and the guide wire 12 are temporarily placed when used, for example, in surgery.

  The tray 1 shown in FIG. 1 is not limited to use at the time of surgery, but various articles used for the surgery (for example, a scalpel knife, a syringe, absorbent cotton, forceps, an introducer sheath, a guide wire, various catheters, etc.). It can also be used as a packaging container mounted as a kit. At the time of use, these articles are taken out and used as a temporary storage for the catheters 11a to 11e.

  Before describing the tray 1, the catheters 11a to 11e and the guide wire (medical instrument) 12 will be described.

  The catheters 11a to 11e are each inserted into a blood vessel (living body) and used. Since the configurations of the catheters 11a to 11e are substantially the same, the catheter 11a will be representatively described below.

  The catheter 11a includes a long catheter body 111 and a hub 112 installed at the proximal end of the catheter body 111.

  The catheter body 111 is a flexible tube. The lumen (lumen) of the catheter body 111 is open to the distal end of the catheter body 111. In addition to being used for inserting the guide wire 12, this lumen can also be used for supplying a chemical solution or the like into the blood vessel or sucking the liquid.

  Further, the outer peripheral surface and the inner peripheral surface of the catheter main body 111 are subjected to processing for reducing (reducing) frictional resistance. Thereby, when moving the catheter 11a along the longitudinal direction, the operation can be performed smoothly. As this treatment, for example, a coating layer of fluororesin such as polytetrafluoroethylene (Teflon coat ("Teflon" is a registered trademark)), silicon coat, hydrophilic polymer coat having lubricity when wet, etc. Is mentioned. In this embodiment, a hydrophilic polymer coat is applied.

  Examples of the constituent material of the catheter body 111 include polyolefins such as polyethylene and polypropylene, polystyrene, polyamide, polyimide, polyetheretherketone, polyurethane, polyester such as polyethylene terephthalate and polybutylene terephthalate, and fluorine resins such as polytetrafluoroethylene. , Polyolefin-based, polystyrene-based, polyamide-based, polyurethane-based, polyester-based, fluororubber-based, chlorinated polyethylene-based thermoplastic elastomers, and combinations of two or more of these (polymer alloys, polymers) Blend).

  A hub 112 is fluid-tightly connected to the proximal end portion of the catheter body 111. The hub 112 is formed of a cylindrical member, and its internal space communicates with the lumen of the catheter body 111. The constituent material of the hub 112 is not particularly limited. For example, various metal materials such as aluminum and stainless steel, various plastics, and the like can be used alone or in combination.

  Examples of the catheters 11a to 11e include a vascular dilatation catheter having a balloon at the tip, and a stent delivery catheter in which a stent is mounted on the balloon at the tip. Various types of balloons and stents need to be prepared in various sizes such as an outer diameter and an axial length when expanded, and they are properly used according to the medical condition (case) of the patient. Further, depending on the medical condition, a plurality of catheters are often used.

  The guide wire 12 is a flexible linear body, and examples of its constituent materials include stainless steel, cobalt-based alloys, pseudo-elastic alloys (including superelastic alloys), and various metals such as piano wires. Materials.

  The tip of the guide wire 12 is rounded. Thereby, the guide wire 12 can be smoothly inserted (moved) in the distal direction in the blood vessel. Further, when the guide wire 12 moves in the blood vessel in the distal direction, it is possible to reliably prevent the blood vessel wall from being damaged by the distal end.

  Moreover, the hydrophilic polymer coat is given to the outer surface of the guide wire 12 similarly to the catheters 11a to 11e.

  The tray 1 shown in FIGS. 1 and 2 includes a tray main body 2, a plurality of (five in the illustrated configuration) support portions 3a, 3b, 3c, 3d and 3e formed integrally with the tray main body 2, Similar to the support portions 3 a to 3 e, a restriction portion 4 formed integrally with the tray main body 2 and plate pieces 5 a, 5 b, 5 c and 5 d fixed to the tray main body 2 are provided. Hereinafter, the configuration of each unit will be described.

  As shown in FIGS. 1 and 2, the tray main body 2 includes a bottom plate 21 and a wall portion 22 erected along the edge of the bottom plate 21.

  The bottom plate 21 has a substantially rectangular (quadrangle) shape in plan view. Although the length of the long side and the short side is not particularly limited, for example, the long side is preferably 300 to 600 mm, and the short side is preferably 250 to 400 mm.

  Since each side is within such a numerical range, the catheters 11a to 11e and the guide wire 12 are stored in the tray 1 (tray body 2) (the state shown in FIG. 1). A loop is formed (see FIG. 1), and excessive bending at this time can be prevented. The catheter 11a (the same applies to the catheters 11b to 11e and the guide wire 12) has a rigidity that tends to be substantially linear in a natural state (a state in which no external force is applied). For this reason, if the catheter 11a is curved, it may jump out of the tray 1 depending on the magnitude of the internal stress at that time.

  The bottom plate 21 is provided with four long convex portions (ridges) 211 along the longitudinal direction thereof.

  On the bottom plate 21, a wall portion 22 is erected along each side thereof. Although it does not specifically limit as height of this wall part 22, For example, it is preferable that it is 30-100 mm, and it is more preferable that it is 50-80 mm.

  Moreover, the wall part 22 can be divided into four parts (wall part 22a, 22b, 22c, 22d) by making each corner | angular part 224 of the baseplate 21 into a boundary part. Each of the wall portions 22a to 22d is formed with a comb-like convex portion 221 that protrudes inward.

  In the tray main body 2, a storage space 23 is defined by the bottom plate 21 and the wall portions 22 a to 22 d (wall portion 22). In the storage space 23, the catheter main body 111 and the guide wire 12 of the catheters 11a to 11e are stored. Moreover, since the storage space 23 can be filled with physiological saline, the catheter body 111 and the guide wire 12 of the catheters 11a to 11e accommodated therein can be infiltrated with physiological saline. Thereby, the catheter main body 111 and the guide wire 12 of the catheters 11a to 11e have lubricity.

  As shown in FIG. 1, the catheter body 111 of the catheter 11a (the same applies to the catheters 11b to 11e) is regulated by the walls 22a to 22d so as to form a loop. Since the catheter 11a is housed in a looped state in this way, when the catheter 11a is removed from the tray 1, the catheter 11a is placed in a direction substantially equal to the tangential direction of the loop (the arrow direction in FIG. 1). By pulling out (pulling out), the take-out operation can be performed easily and smoothly.

  In the vicinity of the center portion of the bottom plate 21, a restricting portion 4 that protrudes from a part of the bottom plate 21 is formed to protrude. The restricting portion 4 has an arc shape in plan view (see FIG. 1). Moreover, as for this control part 4, the outer peripheral surface 41 and the internal peripheral surface 42 incline to the center part side (wall part 22d side) of the baseplate 21, respectively (refer FIG. 2).

  As shown in FIG. 1, the guide wire 12 is regulated such that the shape of the guide wire 12 forms a loop between the inner peripheral surface 42 of the regulating part 4 and the wall parts 22 a, 22 c, and 22 d. Since the guide wire 12 is stored in a looped state in this way, when the guide wire 12 is taken out from the tray 1, the portion that is in contact with the inner peripheral surface 42 of the guide wire 12 is the portion of the inner peripheral surface 42. By pulling upward along the inclination, the take-out operation can be performed easily and smoothly.

  In the housed guide wire 12, the loop size is smaller than the loop size of the housed catheters 11a to 11e. Thereby, the guide wire 12 can be easily taken out separately from the catheters 11a to 11e.

  Further, as described above, since the inner peripheral surface 42 of the restricting portion 4 is inclined, it is possible to prevent (restrict) the guide wire 12 in the storage space 23 from unintentionally moving upward (displacement). it can. Thereby, the guide wire 12 can be reliably stored in a state where the guide wire 12 forms a loop.

  The tray 1 having such a storage space 23 is packaged by a package (for example, a sealed bag) in an unused state. In this case, the storage space 23 (tray 1) is passed through the catheters 11a to 11a such as the guide wire 12 and the like. 11e can be used as a storage unit (storage member) that stores a medical device different from 11e in advance.

  The constituent material of the tray body 2 (including the support portions 3a to 3e and the restriction portion 4) is not particularly limited. For example, polyethylene, polypropylene, polybutadiene, an ethylene-vinyl acetate copolymer or other polyolefin, polyvinyl chloride, Examples thereof include various resin materials such as polyurethane, polystyrene, polymethyl methacrylate, polycarbonate, polyamide, polyester such as polyethylene terephthalate or polybutylene terephthalate, ABS resin, AS resin, ionomer, polyacetal, polyphenylene sulfide, and polyetheretherketone.

  The restricting portion 4 is not limited to being integrally formed with the tray main body 2. For example, the restricting portion 4 is configured separately from the tray main body 2 and is connected to (connected to) the tray main body 2. ) Is also good.

  At the upper end portions of the wall portions 22a to 22d, flange portions 222 that protrude outward are provided. Support portions 3a to 3e are formed to protrude from the upper surface 223 of the flange portion 222 of the wall portion 22a. Each support part 3a-3e supports the hub 112 of the catheters 11a-11e, respectively. Since the structure of each support part 3a-3e is substantially the same, hereafter, the support part 3a is demonstrated typically.

  As shown in FIG. 3, the support portion 3 a includes a pedestal (seat portion) 31 and a columnar head portion 32 that protrudes upward from the pedestal 31.

  The head portion 32 is formed with a recess 322 that opens to the top surface 321 and penetrates the head portion 32 in the radial direction. The recess 322 has a bottom surface (inner surface) 323 that is curved in a C shape (or U shape). By pushing (inserting) the cylindrical hub 112 into the recess 322 from above, the recess 322 is elastically deformed and the hub 112 can be fitted. Thereby, the catheter 11a (hub 112) can be reliably supported. Note that the bottom surface 323 is not limited to being entirely curved, and may have, for example, a bent portion.

  As shown in FIG. 4, the bottom surface 323 of the recess 322 is positioned above the top surface 223 of the flange portion 222 of the wall portion 22a. Thereby, the hub 112 of the catheter 11a can be supported as high as possible. In addition, the bottom surface 323 of the recess 322 is inclined so that the storage space 23 side becomes lower. For this reason, the hub 112 supported by the concave portion 322 at the high position of the tray 1 is inclined downward along the bottom surface 323.

  With such support to the hub 112, a force that presses the catheter body 111 connected to the hub 112 against the bottom plate 21 acts, and the catheter body 111 can be prevented from unexpectedly jumping out of the storage space 23. In addition, the catheter body 111 can be reliably brought into contact with the physiological saline from as close to the root as possible (near the hub 112).

Further, since the support portion 3a is provided so as to protrude above the wall portion 22 of the tray 1 and is disposed at a high position, the hub 112 supported by the support portion 3a can be easily taken out.
The support portions 3b to 3e have substantially the same configuration as the support portion 3a.

  In addition, all inclination angles (alpha) of the bottom face 323 of each support part 3a-3e may be the same, and may mutually differ. When the inclination angles α of the support portions 3a to 3e are different from each other, these inclination angles α gradually increase from the wall portion 22b side (one end side) of the wall portion 22a toward the wall portion 22d side (the other end side). It is preferable to be smaller.

  Each catheter body 111 descends from above the wall portion 22a and contacts the wall portion 22b and also contacts the bottom plate 21. The inclination angle α has a size that assumes that most of the catheter main body 111 is almost linear from the top of the wall 22a to the wall 22b (bottom plate 21). Thereby, it is prevented or suppressed that stress arises in the catheter main body 111.

  The length from the upper part of the wall part 22a of the catheter body 111 to the wall part 22b (bottom plate 21) is, for example, a comparison between the catheter 11a supported by the support part 3a and the catheter 11e supported by the support part 3e. In this case, the catheter body 111 of the catheter 11e is longer than the catheter body 111 of the catheter 11a. For this reason, the inclination angle α of the support portion 3e is smaller than the inclination angle α of the support portion 3a. In addition, the inclination angle α of the support portions 3b to 3d is an intermediate size between the inclination angle α of the support portion 3a and the inclination angle α of the support portion 3e.

  As shown in FIGS. 1 and 2, the support portions 3 a to 3 e are concentrated on the wall portion 22 a (one of the four sides (one long side)) of the tray body 2. In the operation using the catheters 11a to 11e, the user stands on the side of the bed on which the patient lies (for example, the patient's right hand side) facing the patient side, and the wagon on which the instruments such as the tray 1 and the catheter are placed, Generally installed behind the user. When the user takes out the catheter (for example, the catheter 11a) from the tray 1, the user grasps the hub 112 with his right hand and pulls it out to the proximal end. And use each catheter 11a-11e to approach the patient's heart located on the left side of the user. Therefore, it is preferable that the support portions 3a to 3e that support the proximal end portions of the catheters 11a to 11e are provided on the right side of the user.

  For this reason, when the support portions 3a to 3e are concentrated on the wall portion 22a of the tray body 2, the tray 1 can be placed so that the wall portion 22a is on the right side of the user. When taking out the catheters 11a to 11e respectively supported by 3a to 3e, it is not necessary for the user to change the posture one by one, and the operation (takeout operation) becomes easy. Moreover, the hub 112 of each catheter 11a-11e will be arranged in one site | part (wall part 22a) of the tray 1. As shown in FIG. Thereby, each catheter 11a-11e becomes easy to identify, and the catheter to be used can be used reliably.

  Also, the support angle of the hub 112 supported by the support portions 3a to 3e with respect to the wall portion 22a, that is, the angle between the central axis of each recess 322 and the wall portion 22a is different from each other.

Specifically, the support angle of the hub 112 with respect to the wall portion 22a gradually decreases from the wall portion 22b side (one end side) of the wall portion 22a toward the wall portion 22d side (the other end side). In other words, the support angle θ _{1 with} respect to the wall portion 22a of the hub 112 supported by the support portion 3a, the support angle θ _{2 with} respect to the wall portion 22a of the hub 112 supported by the support portion 3b, and the hub supported by the support portion 3c. 112 is a support angle θ ₃ with respect to the wall portion 22a, a support angle θ _{4 with} respect to the wall portion 22a of the hub 112 supported by the support portion 3d, and a support angle θ ₅ with respect to the wall portion 22a of the hub 112 supported by the support portion 3e. The relationship satisfies θ ₁ > θ ₂ > θ ₃ > θ ₄ > θ ₅ (see FIG. 1). However, each support angle is 90 ° or less.

Further, the support angle θ ₁ is an angle at which the support portion 3a can support the catheter 11a (catheter body 111) in the tangential direction of the loop.

Similarly, support angle theta ₂ is support portion 3b becomes an angle such that it can support the catheter 11b in the tangential direction of the loop, the support angle theta ₃ is a supporting portion 3c catheter 11c The support angle θ ₄ is an angle at which the loop can be supported in the tangential direction of the loop, and the support angle θ ₄ is an angle at which the support portion 3 d can support the catheter 11 d in the tangential direction of the loop. , support angle theta _5, the support portion 3e is in the angle such that it can support the catheter 11e in the tangential direction of the loop.

  Since the support angles of the support portions 3a to 3e are set in this way, the catheter body 111 protruding from the hub 112 supported by each of the support portions 3a to 3e can easily and easily loop a loop wound in the same direction. It can be reliably formed. Thereby, the entanglement between the catheter main bodies 111 can be prevented. In addition, since the entanglement between the catheter main bodies 111 is prevented, when taking out one arbitrary catheter out of the five catheters 11a to 11e, another catheter (the same applies to the guide wire 12) is taken out. And the other catheter is reliably prevented from jumping out of the tray 1 unintentionally.

As shown in FIG. 2, adjacent support portions 3a, 3b Interval between (pitch) _{P 1,} adjacent support portion 3b, the interval _{P 2} of 3c between adjacent support portions 3d, 3d distance _{P 3} between the adjacent supporting portion 3d, 3e interval _{P 4} between the is gradually increased toward the wall portion 22d side of the wall portion 22b side of the wall portion 22a. If P ₁ = P ₄ , the angle difference between the support portions 3a to 3e decreases from the support portion 3a to the support portion 3d. For example, in the portion between the support portion 3e and the support portion 3d, the catheter The hubs 112 of 11e and 11d easily interfere with each other and are difficult to take out. Therefore, interference by extending the likely distance P ₃ and the interval P _4, it is possible to prevent interference between the hub 112.

  In addition, this embodiment presupposes that a user is right-handed, and when a user is left-handed, you may replace right and left.

  Further, as described above, the support portions 3a to 3e are formed to protrude from the upper surface 223 of the collar portion 222 of the wall portion 22a.

  If the support portion is formed by cutting the wall portion 22a into a concave shape (slit shape), the support portion that supports the hub 112 is formed as the support angle of the hub 112 becomes smaller. It becomes difficult (impossible). In addition, since the storage space 23 is filled with physiological saline, the physiological saline may leak from the support portion depending on the inclination of the tray 1 (placement state (use state)) or the like. .

  However, in the tray 1, since the support parts 3a-3e are protrudingly formed, it is prevented that such a problem arises.

  Each of the support portions 3a to 3e is not limited to being integrally formed with the tray main body 2, but is configured separately from the tray main body 2 and connected to the tray main body 2 ( It may be connected).

  As shown in FIG. 1, plate pieces 5 a to 5 d that protrude toward the storage space 23 are fixed to the flange portions 222 of the wall portions 22 a to 22 d, respectively. Each of the plate pieces 5a to 5d functions as a protrusion preventing means for preventing the catheters 11a to 11e and the guide wire 12 from protruding from the storage space 23, respectively. In addition, the fixing method to the walls 22a to 22d is not particularly limited. For example, crimp fitting, adhesion (adhesion with an adhesive or a solvent), fusion (heat fusion, high frequency fusion, ultrasonic fusion, etc.) ).

  The plate piece 5a is disposed at the central portion of the wall portion 22a, the plate piece 5b is disposed at the central portion of the wall portion 22b, the plate piece 5c is disposed at the central portion of the wall portion 22c, and the plate piece 5d is It arrange | positions in the center part of wall part 22d.

When the lengths of the plate pieces 5a and 5c are within such a numerical range, it is possible to prevent the plate pieces 5a and 5c from interfering (obstructing removal) when the catheters 11a to 11e are taken out. it can.

  The lengths of the plate pieces 5b and 5d are substantially the same and shorter than the length of the plate piece 5a. The length of the plate piece 5b (the same applies to the plate piece 5d) is preferably 5 to 80%, more preferably 10 to 30% of the length of the wall portion 22b. When the plate piece 5d is positioned on the user's standing position side, it is preferable that the plate piece 5d is smaller because the catheters 11a to 11e and the like can be easily taken in and out and the type can be easily recognized.

  Since the operation of the plate pieces 5a to 5d is almost the same, the plate piece 5c will be described below representatively.

  As shown in FIG. 1, the plate piece 5 c covers the catheter main body 111 of the catheters 11 a to 11 e and the respective portions in contact with the wall portion 22 c of the guide wire 12 from above. In this state, when any one of the five catheters 11a to 11e is taken out, another catheter (same for the guide wire 12) is wound around the taken-out catheter, and the other catheter (catheter body) 111) Even if the portion in contact with the wall portion 22c moves upward, the movement of the plate piece 5c is restricted. Thereby, it is possible to reliably prevent the caught catheter from jumping out of the storage space 23.

  The plate pieces 5a to 5d are configured separately from the tray main body 2 and are not limited to those fixed to the tray main body 2. For example, the plate pieces 5a to 5d are formed integrally with the tray main body 2. Also good.

  As described above, the medical tray of the present invention has been described with respect to the illustrated embodiment. However, the present invention is not limited to this, and each component constituting the medical tray can have any configuration that can exhibit the same function. Can be substituted. Moreover, arbitrary components may be added.

  Further, the shape of the tray body (bottom plate) in plan view is not limited to a rectangle, and may be a square, for example.

  Each support portion supports the hub of the catheter. However, the present invention is not limited to this, and for example, the base end portion (near the hub) of the catheter body may be supported.

  Further, the number of catheters placed on the medical tray is not limited to five, and may be two, three, four, six or more, for example.

  Further, the number of guide wires placed on the medical tray is not limited to one, and may be two or more, for example.

  Further, the plurality of support portions are not limited to being concentrated on one long side of the two long sides, and are, for example, concentrated on the short side or the other long side. May be.

  Further, the plurality of support portions are arranged so that the support angles of the hubs supported by them are all different. In addition to these support portions, one support portion (hub) of the plurality of support portions is also provided. The support part which makes the same support angle as) may be arranged.

  The medical tray of the present invention is a medical tray on which a plurality of catheters having a long flexible catheter body and a hub installed at the proximal end of the catheter body are temporarily placed. And a tray main body defining a storage space in which each catheter main body is stored, the bottom plate and a wall portion standing along the edge of the bottom plate. A plurality of support portions that support a proximal end portion of the catheter, and each of the support portions is provided with respect to one of the wall portions, and is supported by the support portions. Further, the support angles of the proximal end portion of the catheter with respect to the wall portion are arranged different from each other. Therefore, when the catheter main body of the catheter supported by each support portion is stored in the storage space, the loop can be easily and reliably formed. Thereby, the entanglement between the catheters can be reliably prevented. Further, since the entanglement between the catheters is prevented, when one of the plurality of catheters is taken out, the taking-out operation can be performed smoothly. Moreover, another catheter is caught in the taken-out catheter, and it is reliably prevented that the other catheter jumps out of the medical tray. The plurality of support portions are provided concentrated on one side (one long side) of the four sides of the rectangular (rectangular) tray body, and the plurality of support angles are provided from one end side of the one side. When the catheter body of the catheter supported by each support portion is housed in the housing space, the loop wound in the same direction can be easily and reliably formed when gradually decreasing toward the other end side. be able to. Thereby, the entanglement between the catheters can be more reliably prevented. Therefore, the medical tray of the present invention has industrial applicability.
