Hereinafter, the medical tray of the present invention will be described in detail based on a preferred embodiment shown in the accompanying drawings.
1 and 2 are plan views of the medical tray of the present invention (FIG. 1 shows a state in which a medical device is stored, and FIG. 2 shows a state in which no medical device is stored), FIG. FIG. 4 is a perspective view of the medical tray shown in FIG. 1, FIG. 4 is a sectional view taken along line AA in FIG. 1, and FIG. 5 is a sectional view taken along line BB in FIG. Hereinafter, for convenience of explanation, the upper side in FIGS. 3 to 5 is referred to as “upper” or “upper”, and the lower side is referred to as “lower” or “lower”. Also, the left side in FIGS. 1 to 5 is referred to as “base end”, and the right side is referred to as “tip”.

  As illustrated in FIGS. 1 and 3 to 5, a medical tray (hereinafter simply referred to as “tray”) 1 stores a plurality of medical instruments. 1 and 3, the dilator (medical tube) 10, the introducer sheath (hereinafter simply referred to as “introducer”) 20 (medical tube), the females 30a and 30b. , Syringes 40 and 50, injection needle 60, introduction needle (trocar) 70. These medical instruments are used when performing an operation (catheter technique) using a catheter. Moreover, this tray 1 is used in the mounting state mounted in the mounting tray 80 which can accommodate and mount it (refer FIG. 1, FIG. 3-FIG. 5).

  Before describing the tray 1, the dilator 10, introducer 20, scalpels 30 a and 30 b, syringes 40 and 50, injection needle 60, introduction needle (trocar) 70, and placement tray 80 will be described.

  The introducer 20 shown in FIGS. 1 and 5 is used as an introduction port for introducing various catheters into a blood vessel when performing a catheter procedure. The introducer 20 includes an introducer body 201 having a distal end opening 203 opened at the distal end, and a hub 202 that is liquid-tightly joined to a proximal end portion of the introducer body 201.

  The introducer body 201 is composed of a long tube having flexibility. The outer peripheral surface of the introducer body 201 may be subjected to a process for reducing (reducing) the frictional resistance. Thereby, when moving the introducer main body 201 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.

  The hub 202 is formed of a cylindrical body and communicates with the introducer main body 201. Further, a tube 204 functioning as a flow path through which the physiological saline P passes is connected to a side portion of the hub 202. The tube 204 can be connected to a supply means (not shown) for supplying physiological saline P via the connector 205 and the tube 90c. The physiological saline P that has passed through the tube 90 c, the connector 205, and the tube 204 and has flowed into the hub 202 fills the introducer body 201. Thereby, the introducer 20 can be primed. At this time, since the lumen of the introducer body 201 is filled with the physiological saline P, the internal air is removed. The supply means is not particularly limited, and includes a syringe.

The dilator 10 shown in FIGS. 1 and 4 is inserted into a blood vessel in an assembled state inserted into the introducer 20 and then removed. Thereby, the introducer 20 can be inserted into the blood vessel. The dilator 10 includes a dilator main body 101 having a front end opening 103 opened at the front end, and a hub 102 that is liquid-tightly joined to a proximal end portion of the dilator main body 101.

  The hub 102 is formed of a cylindrical body and communicates with the dilator main body 101. Moreover, the tube 90a which functions as a flow path through which the physiological saline P passes is connected to the proximal end side of the hub 102 (see FIG. 1). The tube 90a can be connected to the supply means. The physiological saline P that has flowed into the hub 102 through the tube 90 a fills the dilator body 101. Thereby, the dilator 10 can be primed.

  The scalpels 30a and 30b shown in FIG. 1 cut the living body surface. Each knife 30a, 30b has a blade surface (not shown). The blade surface of the scalpel 30a and the blade surface of the scalpel 30b have different shapes. For example, the scalpel 30a and the scalpel 30b can be selected and used according to the operation.

  The syringe 40 shown in FIGS. 1 and 3 is used when anesthesia is performed, and the syringe 50 is used when a contrast agent is injected into a blood vessel via a catheter.

  The syringe 40 includes a syringe outer cylinder 401 having a mouth portion 404 protruding at the tip, a gasket 402 that slides inside the syringe outer cylinder 401, and a plunger 403 that moves the gasket 402. An anesthetic can be filled in the space surrounded by the syringe outer tube 401 and the gasket 402.

  An injection needle 60 can be attached to the mouth 404 of the syringe 40 (syringe outer tube 401). The injection needle 60 has a needle tube 601 having a sharp needle tip at the tip, and a hub 602 fixed to the proximal end portion of the needle tube 601. The injection needle 60 is attached to the syringe 40 by inserting the mouth portion 404 of the syringe 40 into the hub. In the mounted syringe 40, the filled anesthetic can be administered to the patient by puncturing the living body surface of the patient with the needle tip of the needle tube 601 and pressing the plunger 403.

  The syringe 50 includes a syringe outer cylinder 501 having a mouth portion 504 protruding at the tip, a gasket 502 that slides inside the syringe outer cylinder 501, and a plunger 503 that moves the gasket 502. A contrast agent can be filled in a space surrounded by the syringe outer cylinder 501 and the gasket 502. The mouth 504 of the syringe 50 is connected to the catheter hub. By pressing the plunger 503 in this connected state, the contrast agent can be injected into the blood vessel via the catheter.

Further, in this syringe 50, finger hooks 505 a and 505 b are provided on the outer periphery of the syringe outer cylinder 501, and finger hooks 505 c are provided at the base end of the plunger 503. For example, an index finger can be hung on the finger hanger 505a, a middle finger can be hung on the finger hanger 505b, and a thumb can be hung on the finger hanger 505c. In this state, the plunger 503 can be easily operated. Such finger-hanging portions 505a to 505c are provided corresponding to the fact that a strong force is required at the time of injection because the contrast agent has a higher viscosity (viscosity) than a normal liquid.
In the present embodiment, the syringe 50 may be omitted from the tray 1.

  The introduction needle 70 shown in FIGS. 1 and 3 is composed of a metal inner needle and a resin outer needle, and after puncturing a blood vessel (artery) into which the catheter 8 is to be inserted from a wound hole formed by a scalpel, By removing only the inner needle and inserting a guide wire into the outer needle, it is used to secure an access port for catheter insertion. Thereafter, only the outer needle is removed, and the introducer 20 combined with the dilator 10 is inserted into the blood vessel along the remaining guide wire.

  The mounting tray 80 shown in FIGS. 1 and 3 includes a bottom plate 801 and a wall portion 802 erected along the edge of the bottom plate 801. In the space surrounded by the bottom plate 801 and the wall portion 802, the entire tray 1 in a state where the above-described medical instrument is stored can be stored.

  Further, the bottom plate 801 is formed with a protrusion 803 protruding upward. The protrusion 803 is a part having a circular arc shape in plan view. When the tray 1 is stored in the loading tray 80, the top (upper) 804 of the protrusion 803 contacts the portion on the right side in FIG. 3 (similarly in FIG. 1) with respect to the center of the lower surface (outer surface) 11 of the tray 1. Touch. Thereby, the tray 1 is inclined so that the right side (front end side) in FIG. 3 is higher than the left side (base end side) (see FIGS. 3 to 5).

  In the mounting tray 80, 1 to 3 (three in the drawing) catheters 8 and one guide wire 9 are stored.

  Each catheter 8 has a flexible long catheter body 81 and a hub 82 fluidly connected to the proximal end of the catheter body 81. Each catheter 8 is stored in a state of being wound along the wall portion 802 of the mounting tray 80.

  These catheters 8 are held by the hub holding portion 805 of the mounting tray 80 with the hubs 82 arranged in parallel (see FIG. 1). Each hub 82 is connected to a tube 90b. Each tube 90b is connected to the supply means, and can supply physiological saline P to the catheter 8 via the tube 90b, that is, the catheter 8 can be primed.

  The guide wire 9 is held in a holder 91 made of a tube. The guide wire 9 is housed in a wound state inside each catheter 8 while being held in the holder 91. One end of the holder 91 is connected to the tube 90c (see FIG. 1). The tube 90c is connected to the supply means, and can supply the physiological saline P into the holder 91 through the tube 90c. Similar to the introducer 20, the outer surface of the guide wire 9 is provided with a hydrophilic polymer coat having lubricity when wet. By supplying the physiological saline P into the holder 91, the outer surface of the guide wire 9 comes into contact with (infiltrates) the physiological saline P, and thus has lubricity.

Next, the tray 1 will be described.
As shown in FIG. 2 (the same applies to FIGS. 1 and 3), the overall shape of the tray 1 in plan view is substantially rectangular, and four sides are surrounded by a wall portion 12.

  In addition, the length of the long side direction of the tray 1 is not specifically limited, For example, it is preferable that it is 200-400 mm, and it is more preferable that it is 250-350 mm. Moreover, the length of the short side direction of the tray 1 is not specifically limited, For example, it is preferable that it is 50-200 mm, and it is more preferable that it is 100-150 mm.

  The constituent material of the tray 1 is not particularly limited. For example, polyolefin such as polyethylene, polypropylene, polybutadiene, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyurethane, polystyrene, polymethyl methacrylate, polycarbonate, polyamide, Various resin materials such as polyester such as polyethylene terephthalate or polybutylene terephthalate, ABS resin, AS resin, ionomer, polyacetal, polyphenylene sulfide, polyether ether ketone, and the like can be given.

  The tray 1 includes a storage groove 2 a for storing the dilator 10, a storage groove 2 b for storing the introducer 20, scalpels 30 a and 30 b, syringes 40 and 50, an injection needle 60, formed inside the wall portion 12. And an instrument storage section 3 for storing the introduction needle 70 together. The tray 1 is formed by a mold, and therefore, the storage grooves 2a and 2b and the instrument storage section 3 are integrally formed. Moreover, the storage grooves 2a and 2b and the storage part 3 for instruments are each comprised by the recessed part. Hereinafter, the configuration of each unit will be described.

  Each of the storage grooves 2a, 2b is formed along the longitudinal direction of the tray 1, and is disposed adjacent to each other on the lower side in FIG. With such an arrangement, among the medical instruments stored in the tray 1, the medical instruments (dilator 10 and introducer 20) that perform priming can be stored together (at positions relatively close to each other). In addition, the gripping portions (the hub 102 of the dilator 10 and the hub 202 of the introducer 20) of each medical device can be positioned on the same side (left side in FIG. 2) with respect to the tray 1.

  Thereby, a medical instrument (dilator 10, introducer 20) can be used quickly after priming.

  As described above, in the tray 1, medical instruments (medical tubes) having different uses can be stored in the storage grooves 2a and 2b, respectively. Accordingly, different types of medical instruments can be stored together in one tray 1. In addition, since the occupation area of the two medical tubes can be minimized, the tray 1 itself can be designed to be small, the usability can be improved, the manufacturing cost can be reduced, and the medical treatment can be reduced after use. The amount of waste can be reduced when it is discarded as industrial waste.

  Since the storage groove 2a and the storage groove 2b have substantially the same portion, the storage groove 2a will be described below as a representative.

  As shown in FIG. 4, the bottom surface of the storage groove 2 a is positioned below the first inclined surface 21 via the first inclined surface 21 having the inclination angle α and the step portion 23 over the entire surface. The second inclined surface 22 is formed. The second inclined surface 22 is located on the proximal end side of the first inclined surface 21.

  When the dilator 10 is stored in the storage groove 2a (hereinafter, this state is referred to as a “storage state”), the dilator body 101 is located in the portion where the first inclined surface 21 of the storage groove 2a is formed. A hub is located in a portion of the groove 2a where the second inclined surface 22 is formed.

  In addition, since the first inclined surface 21 is inclined at the inclination angle α as described above, the tip opening 103 of the dilator body 101 is positioned higher than the hub 102 in the housed state.

  Further, as described above, the tray 1 is primed in a state where it is placed (contained) on the placement tray 80. When the tray 1 is placed on the placement tray 80, the tip side portion of the lower surface 11 of the tray 1 comes into contact with the top portion 804 of the protrusion 803 of the placement tray 80. As a result, the entire tray 1 is inclined at an inclination angle θ (see FIG. 4). At this time, the first inclined surface 21 (the same applies to the second inclined surface 22) increases in inclination angle and is inclined at an inclination angle (α + θ) with respect to the horizontal direction. In the state shown in FIG. 4 (mounting state), the tip opening 103 of the dilator main body 101 is located at a higher position than the hub 102.

  In the state shown in FIG. 4, when physiological saline P is injected from the hub 102 into the dilator 10 and the dilator 10 is primed, the physiological saline P flows out from the tip opening 103 of the dilator main body 101. In addition, the inside of the lumen of the dilator main body 101 is completely replaced with the physiological saline P by priming.

  Further, the physiological saline P flowing out from the tip opening 103 flows down in the direction of the arrow in FIG. Thereby, the physiological saline P contacts the outer peripheral surface of at least the tip side portion of the dilator main body 101 easily and quickly. Thereby, the outer peripheral surface of the tip side portion of the dilator main body 101 is wetted and bubbles are removed, so that the dilator 10 can be used quickly. In addition, when using the dilator 10, since the part by the side of the front end of the dilator main body 101 is inserted in the blood vessel, it is sufficient if the outer peripheral surface of the part is moistened. Further, since the entire bottom surface of the storage groove 2a is the first inclined surface 21 and the second inclined surface 22, the physiological saline P can be brought into contact with almost the entire outer peripheral surface of the dilator body 101.

  Further, as described above, the first inclined surface 21 is inclined by the inclination angle θ in the mounted state. If the tray 1 alone is intended to have the first inclined surface 21 inclined at an inclination angle (α + θ), the thickness of the tray 1 is the thickness of the tray 1 of the first inclined surface 21 at the inclination angle α. It will be larger than that. When the thickness of the tray 1 increases, for example, it may be difficult to grip the tray 1 depending on the size.

  In addition, the tray 1 is not limited to the case where the dilator 10 (same as the introducer 20) is infiltrated with the physiological saline P and is placed on the placement tray 80 and the entire tray 1 is inclined. The tray 1 may be horizontal as a whole.

  In addition, although the magnitude | size of inclination-angle (alpha) is not specifically limited, For example, it is preferable that it is 1-6 degrees, and it is more preferable that it is 2-4 degrees.

  Moreover, the magnitude | size of inclination-angle (theta) is although it does not specifically limit, For example, it is preferable that it is 2-8 degrees, and it is more preferable that it is 4-6 degrees.

  Further, the value of “α + θ” that is the inclination angle of the actual medical tube from the horizontal plane is not particularly limited, but it is 3 to 14 in consideration of the effective flow of the physiological saline P and the user's convenience. Degree is preferable, and 6 to 10 degrees is more preferable. Such an angle can be realized by a combination of the tray 1 and the loading tray 80, but α is set to 3 to 14 degrees (more preferably 6 to 10 degrees) and θ is set so as to be realized by the tray 1 alone. May be 0 degrees.

  As shown in FIG. 2, the storage groove 2 a has support means 4 that supports the dilator 10. The support means 4 is composed of five support portions 41a, 41b, 41c, 41d and 41e in which three support points 411, 412 and 413 form a set.

  In the housed state, the dilator 10 has its front end supported by the support portion 41a and the intermediate portion supported by the support portions 41b to 41e (see FIG. 1). Thus, the five support parts 41a-41e are arrange | positioned along the longitudinal direction of the accommodation groove | channel 2a, and can support the dilator 10 of an accommodation state stably. Thereby, when the dilator 10 is primed, the physiological saline P that has flowed out from the tip opening 103 of the dilator 10 is surely brought into contact with the outer peripheral surface of the dilator 10. Moreover, even when the dilator 10 shorter than the dilator 10 of this embodiment is accommodated in the accommodation groove | channel 2a by such arrangement | positioning of the support parts 41a-41e, the said short dilator 10 can be supported reliably.

  Moreover, in each support part 41a-41e, the support points 411 and 413 are mountain-like in one side surface (upper side surface in FIG. 2) of the two side surfaces which the accommodation groove | channel 2a opposes among the support points 411-413. The support point 412 is formed to protrude in a mountain shape on the other side surface (the lower side surface in FIG. 2). In the housed state, these support points 411 to 413 are in contact with the outer peripheral surface of the dilator body 101 of the dilator 10, and the dilator 10 is sandwiched between the contact portions. With such a storage state, the dilator 10 can be supported more stably. Moreover, the dilator 10 can be easily taken out by grasping and lifting the dilator 10 in the housed state.

  Moreover, in each support part 41a-41e, the support points 411-413 are arrange | positioned along the longitudinal direction of the storage groove | channel 2a, and are arrange | positioned (different position). Specifically, the support points 411 and 413 are arranged adjacently shifted along the longitudinal direction of the storage groove 2a, and the support point 412 is a support point 411 and a support point 413 in the longitudinal direction of the storage groove 2a. It is arranged between.

  Since the support points 411 to 413 are arranged in this way, the physiological saline P meanders and flows in the vicinity of the support portions 41a to 41e. (See FIG. 1). Thereby, especially in the support parts 41a-41e, the physiological saline P will contact the outer surface of the dilator 10 (dilator main body 101) uniformly.

Moreover, by arrangement | positioning of such support points 411-413, in each support part 41a-41e, the flow of the physiological saline P is not prevented (it does not inhibit), but flows smoothly and reliably toward the downstream. If the support point 411 and the support point 412 protrude from the same position in the longitudinal direction of the storage groove 2a, the physiological saline P flowing from the upstream side may stop at that portion. However, in this embodiment, such a problem is prevented from occurring, and a smooth and quick flow of the physiological saline P can be ensured.
Note that the storage groove 2b has substantially the same configuration as the storage groove 2a.

  As shown in FIGS. 1, 2 and 4, the support portion 41a located in the middle of the storage groove 2a, that is, the most upstream side of the storage groove 2a, and the support portion positioned upstream next to the support portion 41a The storage part 24 is formed between 41b. The reservoir 24 is a portion that stores the physiological saline P that has flowed down the first inclined surface 21. The reservoir 24 has a width larger than the width of the first inclined surface 21 (see FIGS. 1 and 2) and a depth deeper than the depth of the first inclined surface 21 (see FIG. 4).

  By providing such a reservoir 24, when the dilator 10 is primed and the physiological saline P flows out from the tip opening 103, the portion on the tip side of the dilator 10 from the tip portion 103 is more than that. The physiological saline P can be preferentially brought into contact with the base end portion. As described above, when the dilator 10 is used, it is sufficient that the outer peripheral surface of the tip side portion of the dilator main body 101 has lubricity. By the action of the reservoir 24, the outer peripheral surface of the tip side portion of the dilator body 101 mainly has lubricity.

  Note that the storage portion 24 is omitted in the storage groove 2b. This is because, unlike the dilator body 101, the introducer body 201 needs to wet the entire outer surface.

  A drainage port (drainage part) 25 is provided on the downstream side of the storage groove 2a. The drainage port 25 is a portion where the base end portion of the storage groove 2a is opened (opened) outward. For example, when the physiological saline P overflows from the storage unit 24, the physiological saline P that has flowed down the first inclined surface 21 and the second inclined surface 22 in order is reliably transferred to the mounting tray 80 via the drainage port 25. Can be discharged.

  A drainage port (drainage part) 26 is also provided on the downstream side of the storage groove 2b. The drain port 26 is a portion where the side wall of the base end portion of the storage groove 2b is opened (opened) toward the storage groove 2a. The physiological saline P that has flowed down in the storage groove 2 b flows into the storage groove 2 a via the drainage port 26, and is reliably discharged to the mounting tray 80 via the drainage port 25.

  As shown in FIGS. 1 to 3, on the side of the storage groove 2 b opposite to the storage groove 2 a, scalpels 30 a and 30 b and syringes 40 and 50 that are used in association with the dilator 10 and the introducer 20 during surgery. The instrument storage unit 3 for storing the injection needle 60 and the introduction needle 70 is disposed.

  As described above, the instrument storage portion 3 is formed of a recess, and the recess is partitioned by a plurality of wall portions.
