Further, the lower limit value and / or the upper limit value of the numerical range described in this disclosure may be a numerical value within that numerical range and may be replaced with the numerical values shown in the examples. The expression "X to Y" indicating a numerical range means "X or more and Y or less". When the specific explanation described for one embodiment also applies to other embodiments, the explanation may be omitted in other embodiments.

[0010] FIG. 1 and FIG. 2 are diagrams showing a holder 1 for medical tubing according to a first embodiment of the present disclosure. Here, the medical tubing 3 includes not only a hollow medical tube such as an intravenous drip tube but also a solid tube such as wiring (e.g., electric wire) of a medical device. In the present embodiment, the holder 1 for medical tubing includes a block 5, and the block 5 is, for example, a plate-like block having a certain thickness between a front surface 6 and a back surface 7 formed by an injection molding method, and includes a first side wall 10, a second side wall 20, a third side wall 30, and a fourth side wall 40 around a middle wall 8. When the block 5 is viewed from the side facing the front surface 6, the outer peripheral surfaces of the first side wall 10 and the third side wall 30 are each formed into a convex curved surface that bulges outward from each other. In the present embodiment, the portions connecting the first side wall 10, the second side wall 20, the third side wall 30, and the fourth side wall 40 to the front surface 6 or the back surface 7 are chamfered curved surfaces. The size of the block 5 can be 5 to 200 mm × 5 to 250 mm, 10 to 150 mm × 10 to 200 mm, or 10 to 100 mm × 10 to 120 mm. Examples of the material of the block 5 include resins such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS), and low-density polyethylene (LDPE) can be preferably used in particular. The block 5 preferably contains at least 50% by mass or more of these resin materials, more preferably 70% by mass or more, and even more preferably 90% by mass or more. Colorants, other additives, etc. can be added to the block 5. The colorant is not particularly limited, but pigments, dyes, etc. can be used to obtain a desired color. The block 5 can be manufactured by a normal molding method, for example, an injection molding method or a die-cutting method.

[0011] The holder 1 for medical tubing is used by suspending it such that the second side wall 20 of the block 5 is on top, the fourth side wall 40 is at the bottom, or the fourth side wall 40 is on top and the second side wall 20 is at the bottom. The holder 1 for medical tubing can be used to hold medical tubing of any diameter, for example, it can hold medical tubing having an outer diameter of 0.4 to 20.0 mm, 0.7 to 15.0 mm, 1.0 to 14.0 mm, or 2.0 to 10.0 mm.

[0012] In the middle wall 8, a first opening 60 is formed at its central part, and a second opening 75 that constitutes a telescopic device connection part is formed on the side of the second side wall 20 at its upper part. A tube slot 51 is formed between the middle wall 8 and the first side wall 10. In the present embodiment, the holder 1 for medical tubing has only one first opening 60.

[0013] At the first side wall 10, the first slot end 53 of the tube slot 51 is open. The tube slot 51 is configured such that the second slot end 55 on the side of the middle wall 8 communicates with the first opening 60. Thus, the block 5 is provided with the tube slot 51, the tube slot 51 has the first slot end 53 and the second slot end 55, and the first side wall 10 includes the first slot end 53. When the block 5 is viewed from the side facing the surface 6, the width of the tube slot 51 is formed to gradually narrow from the first slot end 53 toward the second slot end 55. The width of the first slot end 53 can be 0.5 to 20 mm, 1 to 16 mm, or 2 to 12 mm, and the width of the second slot end 55 can be 0.5 to 15 mm, 1 to 10 mm, or 2 to 7 mm, but the width of the second slot end 55 is narrower than the width of the first slot end 53. For this reason, it is easier to insert the medical tubing 3 into the tube slot 51. In one embodiment, the width of the second slot end 55 is 50 to 70% of the width of the first slot end 53.

[0014] The tube slot 51 and the first opening 60 penetrate through the front surface 6 and the back surface 7. Therefore, by inserting the medical tube 3 through the first slot end 53, the second slot end 55, and the communication portion 65 up to the first opening 60, the medical tube can be held in the first opening 60. By holding only the desired medical tube in the first opening 60, entanglement with another medical tube can be prevented, and the burden on medical staff can be further reduced.

[0015] The width of the first opening 60 is formed to gradually narrow from its center point 61 toward the communication portion 65 with the tube slot 51. The width of the communication portion 65 between the tube slot 51 and the first opening 60 can be 0.5 - 15 mm, 1 - 10 mm, or 2 - 7 mm, and the width at the center point 61 of the first opening 60 can be 0.5 - 15 mm, 1 - 10 mm, or 2 - 7 mm. However, the width of the communication portion 65 is narrower than the width at the center point 61 of the first opening 60. In one embodiment, the width of the communication portion 65 is 20 - 40% of the width at the center point 61 of the first opening 60. The shape of the first opening 60 is a perfect circle, but it is not particularly limited as long as it can hold the medical tube. For example, it can be a substantially circular shape, a substantially polygonal shape, a substantially fan-shaped, or a substantially star-shaped.

[0016] On the second side wall 20, a male fitting portion 21 is formed. The male fitting portion 21 includes a neck portion 22 and a protruding portion 23. The neck portion 22 connects the second side wall 20 and the protruding portion 23. In this embodiment, the width of the neck portion 22 is configured to be thicker than 50% of the width of the protruding portion 23. The protruding portion 23 has two protruding end portions 24 facing in opposite directions. In this embodiment, the protruding portion 23 is arranged at an angle of 0° ± 10° with respect to the second side wall 20. Preferably, the protruding portion 23 is arranged at an angle of 0° ± 5° with respect to the second side wall 20.

[0017] The fourth side wall 40 is provided with a female fitting portion 41. This female fitting portion 41 includes a third opening 42 that opens downward in the fourth side wall 40, and a fourth opening 43 that is continuous inward in the direction of the middle wall 8 from the third opening 42 and extends left and right in the width direction of the third opening 42. The male fitting portion 21 of another separately manufactured medical pipe holder 1 can be fitted into the female fitting portion 41 so that they are connected to each other with a slight gap. In this way, the female fitting portion 41 has a shape that can be freely fitted with the male fitting portion 21. In the present embodiment, the second side wall 20 is provided with the male fitting portion 21, and the fourth side wall 40 is provided with the female fitting portion 41. However, as long as one of the second side wall 20 and the fourth side wall 40 is provided with the male fitting portion 21 and the other is provided with the female fitting portion 41 having a shape that can be freely fitted with the male fitting portion 21. For example, the second side wall 20 may be provided with the female fitting portion 41, and the fourth side wall 40 may be provided with the male fitting portion 21. In the present embodiment, the medical pipe holder 1 is provided with one male fitting portion 21 and one female fitting portion 41 respectively. With this configuration, the method of connecting a plurality of medical pipe holders of the present invention can be uniquely understood, and it is also easier to understand visually, and the burden on medical staff can be further reduced.

[0018] As shown in FIG. 3 , when the block 5 is viewed from the side facing the front surface 6, the first opening 60 is located closer to the fourth side wall 40 than the center line 52 (including the extended portion) of the tube slot 51, and the first opening 60 does not overlap the center line 52 of the tube slot 51. In this embodiment, the first opening 60 has a perfect circular shape, and the angle α formed by the line segment 67 passing through the center point 61 of the first opening 60 and the midpoint 66 of the connecting portion 65 with the second slot end 55 and the center line of the tube slot 51 is 45° to 135°. The reason for adopting the above configuration is that in order to remove the medical tubing from the medical tubing holder 1, it is necessary to move the medical tubing in at least two different directions. Therefore, even if a force is unintentionally applied to the medical tubing in one direction, the medical tubing is less likely to come off the medical tubing holder 1. It is more preferable that the angle α formed by the line segment passing through the center point 61 of the first opening 60 and the midpoint of the communicating portion 65 and the center line of the pipe slot 51 is 60° to 120°.

[0019] The extension device connection part 70 is a part for connecting to the extension device 80. In this embodiment, the extension device connection part 70 is a second opening 75 that does not communicate with any side wall and penetrates the front surface 6 and the back surface 7. The shape of the second opening 75 is circular in FIG. 1, but is not particularly limited as long as it can be connected to the extension device 80, and can be, for example, approximately circular or approximately polygonal. On the other hand, the male fitting portion 21 can engage with the engaging portion 82 of the telescopic device 80 described below, and can therefore also function as the telescopic device connecting portion 70. In this case, there is no need to further provide a second opening 75 as the telescopic device connecting portion 70. Furthermore, the female fitting portion 41 can engage with the engaging portion 82 of the telescopic device 80 described below, and can therefore function as the telescopic device connecting portion 70. In this case, there is no need to further provide a second opening 75 as the telescopic device connecting portion 70.

[0020] As shown in FIG. 4, at least two, preferably at least three, more preferably at least four holders 1 for medical tubes of the present embodiment can be combined to form a set 100 of holders for medical tubes. The set 100 of holders for medical tubes can be manufactured by fitting and connecting the female fitting portion 41 of the first holder 1 for medical tubes and the male fitting portion 21 of the second holder 2 for medical tubes. At this time, the color of the block 5 of the plurality of holders 1 for medical tubes and the color of the block 5 of the second holder 2 for medical tubes can be made different from each other.

[0021] As shown in FIG. 5, prepare the first holder 1 for medical tubes and the second holder 2 for medical tubes, fit and connect the female fitting portion 41 of the first holder 1 for medical tubes and the male fitting portion 21 of the second holder 2 for medical tubes, insert the first medical tube 3 into the first opening 60 of the first holder 1 for medical tubes, and insert the second medical tube 4 into the first opening 60 of the second holder 2 for medical tubes, whereby the holder 1 for medical tubes can be used.

[0022] In the second embodiment of the present disclosure, the holder 1 for medical tubes further includes a telescopic device 80 in addition to the block 5. As shown in FIG. 7, the telescopic device 80 includes a cord 81, an engaging portion 82 provided at an end of the cord 81, and a case 83 for winding and unwinding the cord 81. A shaft (not shown) in the case 83 for winding the cord 81 is provided with a spring (not shown) for biasing the cord 81 in the winding direction and a stop mechanism (not shown) for stopping the winding. Thus, the cord 81 is telescopic. The telescopic device 80 can be connected to the male fitting portion 21, the female fitting portion 41 or the second opening 75 via the engaging portion 82. In the present embodiment, the telescopic device 80 is connected to the second opening 75 via the engaging portion 82. Thus, the engaging portion 82 is connected to the block 5. Examples of the shape of the cord 81 include a flat cord shape, a round cord shape, and a flat-round cord shape. As the material of the cord 81, vinyl chloride or the like can be used. As the engaging portion 82, a carabiner, a hook or the like can be used.

[0023] The usage method of the holder 1 of the medical tube equipped with the telescopic device 80 will be described below. By connecting the engaging portion 82 of the telescopic device 80 to the block 5 of the holder 1 of the medical tube and adjusting the length of the telescopic device 80, the holder 1 of the medical tube can be used. By shortening the length of the telescopic device 80, the excess portion of the medical tube can be prevented from touching the floor. Also, by stretching the telescopic device 80, a margin can be created for the medical tube when performing a treatment or the like.

[0024] Next, the usage method of the holder 1 of the medical tube will be described. As shown in FIG. 7, for example, the holder 1 of the medical tube is suspended via the telescopic device 80 on an IV stand installed on the bedside. At this time, one engaging portion 82 of the telescopic device 80 is hooked on a hook provided on the IV stand. Then, the other engaging portion 82 is hooked on the telescopic device connection portion 70 of the holder 1 of the medical tube. And the medical tube 3 such as for IV connected to the patient is attached to the holder 1 of the medical tube. In this case, the medical tube 3 is inserted from the first slot end 53 to the second slot end 55 of the holder 1 of the medical tube, and further inserted into the first opening 60 through the communication portion 65. When the medical tube 3 is attached to the holder 1 of the medical tube in this way, the width of the tube slot 51 gradually narrows from the first slot end 53 to the second slot end 55, and the width of the first opening 60 gradually narrows from its center point 61 toward the communication portion 65 with the tube slot 51. The first opening 60 is located on the side of the fourth side wall 40 rather than on the center line 52 (including the extended portion) of the tube slot 51. The first opening 60 and the center line 52 of the tube slot 51 do not overlap, and the angle α formed by the line segment 67 passing through the midpoint 66 of the communication portion 65 between the center point 61 and the second slot end 55 and the center line of the tube slot 51 is 45° to 135°. Therefore, the medical tube 3 once inserted into the first opening 60 will not easily come off to the outside. In the attachment of the above-mentioned medical tubing 3, after passing one medical tubing 3 through the holder 1 for one medical tubing, the holders 1 for a plurality of medical tubings are connected, and the telescopic device 80 is attached to the topmost holder 1 for the medical tubing and suspended on the bedside. As shown in FIG. 7, by shortening the length of the telescopic device 80, the surplus portion of the medical tubing 3 is prevented from touching the floor. As shown in FIG. 8, by stretching the telescopic device 80, a margin is created for the medical tubing 3 during treatment, cleaning, or position change. After the end, the length of the telescopic device 80 is restored to its original state. When moving for treatment or imaging examination, the telescopic device 80 is removed and carried along.

[0025] As described above, according to the above-mentioned holder 1 for the medical tubing, even if a force is unintentionally applied to the medical tubing 3 in one direction after the medical tubing 3 is once inserted into the first opening 60, the medical tubing 3 is suppressed from being accidentally detached to the outside, and the burden on medical staff is reduced. In addition, by shortening the length of the telescopic device 80, the surplus portion of the medical tubing 3 can be prevented from touching the floor, and by stretching the telescopic device 80, a margin can also be created for the medical tubing 3 during treatment, cleaning, or position change.

[0026] FIG. 7 shows a case where the medical tubing 3 is attached using a plurality of holders 1 for the medical tubing. When using a plurality of holders 1 for the medical tubing, the female fitting portion 41 of the first holder 1 for the medical tubing and the male fitting portion 21 of the second holder 2 for the medical tubing are fitted and connected for use. In FIG. 7, the blocks 5 of the holder 1 for the medical tubing are color-coded, and the type of drug flowing through the medical tubing 3 and the inserted site can be easily identified, facilitating the grasp of the above matters during drug administration or shift handover. In addition, the connection of the plurality of holders 1 for the medical tubing is maintained, preventing unnecessary entanglement between the medical tubings 3.

[0027] Next, with reference to FIGS. 5 and 6, a case where medical tubing 3 connected to central venous catheter 90 is attached to medical tubing holder 1 will be described. As shown in Figure 6, a central venous catheter 90 has a catheter portion 91 and multiple pipes 92 branching off from the catheter portion 91, with a connector 93 provided at the tip of each pipe 92. Medical pipes 3 are connected to the connectors 93 provided at the tips of the pipes 92 branching off from the central venous catheter 90. The multiple connectors 93 of the central venous catheter 90 are each a different color. Furthermore, the color of the connector 93 matches the color of the block 5 of the medical pipe holder 1 to which the medical pipes 3 connected to the connector 93 are attached. Note that the symbols A, B, and C shown in Figure 5 correspond to A, B, and C in Figure 6. A first connector 93 and a second connector 94 of different colors are provided at the tip of each of the tubings 92 branching off from the central venous catheter 90, and a first medical tubing 3 and a second medical tubing 4 are connected to the first connector 93 and the second connector 94, respectively. At this time, the first medical tubing 3 is attached to a first medical tubing holder 1 having a block 5 of the same color as the first connector 93, and the second medical tubing 4 is attached to a second medical tubing holder 2 having a block 5 of the same color as the second connector 94. In this example, the same effect as when a plurality of holders 1 for medical piping are used can be obtained.
