  Hereinafter, a precision coil tray according to an embodiment of the present invention will be described with reference to the drawings. In addition, this embodiment demonstrates the case where the coil wire (precision coil) which is one part of the guide wire used for catheter treatment is accommodated.

  FIG. 1 is a plan view of a precision coil tray in the present embodiment, and FIG. 2 is a side view. 3 is a sectional view taken along line AA in FIG. 1, FIG. 4 is a sectional view taken along line BB in FIG. 1, and FIG. 5 is a sectional view taken along line CC in FIG. FIG. 6 is an enlarged perspective view of a portion D in FIG.

  As shown in FIGS. 1 to 6, a precision coil tray (hereinafter referred to as a tray) 10 includes a storage portion 11 having a substantially rectangular shape in plan view, and a peripheral wall portion 13 formed so as to surround the storage portion 11. It is equipped with. The tray 10 is, for example, molded with a material in which 5% by weight of carbon is mixed with ABS resin, and has a thickness of about 1.5 mm. In other words, the carbon is mixed to make it conductive, and the color of the tray 10 is black.

  In the storage portion 11, a groove-like slot portion 15 that stores the coil wire 1 and a separator portion 17 that partitions between adjacent slot portions 15 and 15 are alternately formed in parallel. The slot portion 15 is formed with a groove portion along the direction in which the coil wire 1 is guided. That is, in the cross section in the direction orthogonal to the direction in which the coil wire 1 is guided (see FIG. 5), the slot portions 15 and the separator portions 17 are alternately formed in an uneven shape. One slot portion 15 is configured to accommodate one coil wire 1.

  An introduction portion 21 for guiding the coil wire 1 is formed at one end of the slot portion 15, and a wall portion 22 is formed at the other end of the slot portion 15. The introduction part 21 is formed so as to open between the adjacent separator parts 17, 17, and the coil wire 1 manufactured by a winding machine (not shown) passes through the introduction part 21 and enters the slot part 15. It is comprised so that it may be guided to. In addition, the bottom surface 16 of the slot portion 15 has a curved cross-sectional shape in a direction orthogonal to the direction in which the coil wire 1 is guided. Here, since the coil wire 1 is formed in a substantially cylindrical shape, the coil wire 1 can be disposed at a predetermined position on the bottom surface 16 when the coil wire 1 is stored in the slot portion 15. Further, a protrusion 18 protruding downward is formed at the bottom of the bottom surface 16 of the slot 15. The protrusion 18 is formed in a size that can be fitted into the slot 15 of the tray 10 disposed immediately below when the tray 10 is stacked in the vertical direction. The coil wire 1 has, for example, a shape in which a winding is wound in a substantially cylindrical shape having an outer diameter of about 0.2 to 0.3 mm and a total length of about 200 mm, and the winding density is partially different. It is formed as follows.

  FIG. 7 shows a fitting state of the slot portion 15 when the trays 10 are stacked in the vertical direction. As shown in FIG. 7, the protrusion 18 of the upper tray 10A is fitted into the slot 15 of the lower tray 10B. At this time, the coil wire 1 is arranged in the slot portion 15, but the shape of the projection portion 18 is determined so that the coil wire 1 does not contact the projection portion 18.

  Further, an inclined portion 23 is formed on the introduction portion 21 side of the storage portion 11 so that the coil wire 1 is reliably guided into the slot portion 15. The inclined portion 23 extends upward from the bottom surface 16 of the slot portion 15. The upper end of the inclined portion 23 is connected to the upper surface 13 a of the peripheral wall portion 13.

  The separator portion 17 is formed so as to connect the upper ends of the adjacent slot portions 15 and 15 and be substantially parallel to the horizontal direction. The separator portion 17 is not formed on the inclined portion 23. Further, one end portion of the separator portion 17, that is, the end portion on the side where the introduction portion 21 is formed, is formed in a tapered shape along the direction in which the coil wire 1 is guided (see FIG. 6). By making the one end part of the separator part 17 into a tapered shape, the width of the introduction part 21 can be increased. That is, the coil wire 1 can be reliably guided into the desired slot portion 15. If one end portion of the separator portion 17 is configured to taper in a curved shape in plan view, there is no corner at the tip of the separator portion 17, and the coil wire 1 is guided when the coil wire 1 is guided to the slot portion 15. Even if it hits the separator portion 17, it is possible to more safely prevent the coil wire 1 from being damaged.

  Grooves 31 are formed on the upper surface 13a of the peripheral wall 13 of the tray 10 over the entire circumference in the circumferential direction. Also, a skirt portion 32 is formed on the lower surface 13b of the peripheral wall portion 13 so as to protrude downward over the entire circumference in the circumferential direction. The groove portion 31 and the skirt portion 32 are configured to be fitted when the tray 10 is stacked in the vertical direction. That is, the skirt portion 32 of the upper tray 10A and the groove portion 31 of the lower tray 10B are fitted. With this configuration, even if a plurality of trays 10 are stacked, the trays 10 are stably stacked, and the laminated body of the trays 10 can be overturned due to vibrations that occur during transportation and the like, so that the coil wire 1 falls from the tray 10. Can be prevented.

Next, a method for storing and transporting the coil wire 1 using the tray 10 of the present embodiment will be described.
Since the coil wire 1 is manufactured by a winding machine (not shown), a tray 10 is arranged near the winding machine. The coil wire 1 manufactured by the winding machine is transported to the immediate vicinity of the tray 10 by an arm of the winding machine. When the coil wire 1 reaches the inclined portion 23 of the tray 10, the coil wire 1 leaves the arm of the winding machine and is supplied to the tray 10.

  As shown in FIG. 8, the coil wire 1 supplied to the inclined portion 23 of the tray 10 is guided to the introduction portion 21 of the slot portion 15 so as to slide down the inclined portion 23.

  Further, as shown in FIG. 9, the tip end of the coil wire 1 guided to the introduction portion 21 is guided into the slot portion 15. At this time, even if the tip of the coil wire 1 hits the tapered tip of the separator portion 17 located on both sides of the introduction portion 21, the coil wire 1 is guided directly into the slot portion 15 along the surface of the tip. The coil wire 1 is guided from the introduction portion 21 into the slot portion 15 and placed on the bottom surface 16 of the slot portion 15. At this time, the coil wire 1 is positioned completely in the slot portion 15 and is arranged so that the rear end portion of the coil wire 1 does not protrude from the introduction portion 21.

  Next, another coil wire 1 is also disposed in the slot portion 15 in the same manner as described above. At this time, the coil wire 1 is sequentially stored in the slot portion 15 adjacent to the slot portion 15 in which the coil wire 1 is stored immediately before.

  Subsequently, as shown in FIG. 10, when the coil wires 1 are stored in all the slot portions 15, the cushioning material 41 is arranged so as to cover the slot portions 15. The buffer material 41 is made of, for example, a soft sponge, and is arranged for all the slot portions 15. Further, the buffer material 41 is also disposed on the upper surface of the inclined portion 23. By disposing the buffer material 41 on the inclined portion 23, the coil wire 1 can be prevented from jumping out from the introduction portion 21.

  When the buffer material 41 is arranged, the trays 10 are stacked. When the trays 10 are stacked, the cushioning material 41 is crushed and deformed so as to fill the gap in the slot portion 15. That is, as shown in FIG. 11, the coil wire 1 and the buffer material 41 are arranged between the slot portions 15 and 15 stacked in the vertical direction. By comprising in this way, it can prevent reliably that the coil wire 1 moves by vibration etc. with the buffer material 41. FIG.

  Further, when the trays 10 are stacked in the vertical direction, the grooves 10 and the skirt portions 32 of the peripheral wall 13 of the tray 10 stacked in the vertical direction are fitted to each other, whereby the trays 10 can be stacked stably.

  Subsequently, when the coil wire 1 stored in the tray 10 transported to the destination is actually used, the cushioning material 41 disposed on the tray 10 is removed, and the coil wire 1 stored in the slot portion 15 is taken out. . At this time, the coil wire 1 is taken out by tweezers or the like, but in the present embodiment, the shape of the bottom surface 16 of the slot portion 15 is a curved surface, so that the coil wire 1 can be easily taken out by tweezers.

  Further, since the tray 10 is molded with a material in which 5% by weight of carbon is mixed with ABS resin, the tray 10 is made conductive. Therefore, since the tray 10 can prevent the generation of static electricity, when the coil wire 1 is grasped with tweezers, the static electricity is transmitted through the coil wire 1 and discharged, thereby preventing the coil wire 1 from being damaged. be able to. Furthermore, since the tray 10 is formed in black, the visibility of the silver-white coil wire 1 can be enhanced, and the coil wire 1 can be easily taken out with tweezers.

  Then, by passing the core wire (catheter) through the coil wire 1, it can be used for catheter treatment.

  According to this embodiment, since the introduction side end portion of the separator portion 17 is tapered, the introduction portion 21 corresponding to the inlet of the slot portion 15 that houses the coil wire 1 can be formed wide. The coil wire 1 can be easily accommodated in the slot portion 15 at a desired position. Therefore, the coil wire 1 manufactured by the winding machine can be automatically stored in the desired slot portion 15 as it is without human intervention. As a result, the coil wire 1 can be efficiently accommodated in the desired slot portion 15 and quality deterioration of the coil wire 1 can be prevented.

  Further, by supplying the manufactured coil wire 1 to the inclined portion 23, the coil wire 1 moves downward along the inclined portion 23 and is guided from the desired introduction portion 21 to the slot portion 15. Therefore, the coil wire 1 can be stored in the slot portion 15 more efficiently.

  Further, since the bottom surface 16 of the slot portion 15 is formed in a curved shape, the position of the coil wire 1 can be held when the coil wire 1 is stored in the slot portion 15. Accordingly, it is possible to prevent the coil wire 1 from being damaged by moving in the slot portion 15 during transportation or the like. Further, by holding the coil wire 1 at the deepest portion of the slot portion 15, the coil wire 1 can be easily taken out with tweezers or the like when the coil wire 1 is used.

  Moreover, since the groove part 31 was formed in the upper surface 13a in the surrounding wall part 13, and the skirt part 32 was formed in the lower surface 13b, even if the tray 10 is laminated | stacked up and down, it prevents that trays 10 and 10 mutually shift. Can do. Accordingly, it is possible to prevent the coil wire 1 from being damaged by moving in the slot portion 15 during transportation or the like. Moreover, since the several coil wire 1 can be conveyed simultaneously, transportation efficiency can be improved.

  Furthermore, when the trays 10 are stacked in the vertical direction, the coil wire 1 housed in the slot 15 can be prevented from coming into contact with the protrusions 18 of the tray 10 positioned above and being damaged, and the The coil wire 1 is configured to be prevented from dropping off from the slot portion 15 due to vibration generated at times. Therefore, quality deterioration of the coil wire 1 can be prevented, and the transport efficiency can be improved.

  Since the tray 10 is stacked in the vertical direction with the buffer material 41 disposed on the slot portion 15 and the inclined portion 23, the coil wire 1 can be inserted into the slot even if vibration occurs during transportation. It is possible to prevent movement within the portion 15. Therefore, quality deterioration of the coil wire 1 can be prevented more reliably, and the transport efficiency can be further improved.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in this embodiment, although the case where the coil wire used for a catheter treatment as a precision coil is accommodated in a tray was demonstrated, it can utilize as a tray which accommodates a precision coil. Note that the size of the slot portion may be set in accordance with the size of the precision coil.
Moreover, although this embodiment demonstrated the case where a separator part was not formed in an inclination part, you may form a separator part also in an inclination part.
