Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a support device for dialysis tubing. Background Technology

[0002] The establishment of an extracorporeal circulation system in blood purification therapy is crucial to ensuring the effectiveness and safety of the treatment. The extracorporeal circulation system refers to the closed-loop circulation formed by the connection of the patient, dialysis equipment, and dialyzer through dialysis tubing. The patient's blood is drawn out through an arterial puncture needle and flows into the arterial tubing. The purified blood flows through the venous tubing into the venous puncture needle and is then returned to the patient's body. Extracorporeal circulation tubing is a crucial channel for drawing blood from the patient, purifying it outside the body, and returning it to the body. Appropriate tubing length ensures smooth blood flow and facilitates dialysis treatment. To facilitate the operation of medical staff when connecting tubing and to increase patient comfort (such as changing from lying flat to turning on the side), the arterial and venous segments of the dialysis tubing are often designed to be relatively long. However, long tubing is prone to tangling and sagging. Due to gravity, sagging tubing may pull on the arterial and venous puncture needles, increasing the risk of needle dislodgement and leakage at the connection point. To reduce these risks, medical staff often wrap the long tubing around themselves and tie it to the bed rails. However, this method still cannot completely eliminate the risk of needle dislodgement and blood loss caused by tubing sagging due to gravity. Furthermore, the need to tie up the long tubing for each treatment undoubtedly increases the workload of medical staff.

[0003] Therefore, how to avoid the risk of blood loss caused by the sagging of tubing due to gravity is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a support device for dialysis tubing, which can prevent the risk of blood loss caused by the dialysis tubing sagging due to gravity.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A support device for dialysis tubing, comprising:

[0007] A first fixing member and a second fixing member, one of which is connected to the dialysis equipment and the other is connected to the nursing bed. A support tube is provided between the first fixing member and the second fixing member. The support tube is a hollow tubular structure with a first port and a second port that are connected to each other at its two ends. One of the first port and the second port is used for the insertion of the dialysis tubing, and the other port is used for the exit of the dialysis tubing. The support tube is used to support the dialysis tubing inserted therein.

[0008] In one possible implementation, the second fixing member includes a first clamping plate and a second clamping plate that are rotatably connected, and a torsion spring is provided between the first clamping plate and the second clamping plate for driving the first clamping plate and the second clamping plate to clamp onto the nursing bed or dialysis equipment.

[0009] In one possible implementation, the first and second clamping plates are provided with a clamping part with a semi-circular structure at the end opposite to the bearing channel.

[0010] In one possible implementation, two first semicircles are provided in the middle of the first clamping plate and on the side near the second clamping plate, and two second semicircles are provided in the middle of the second clamping plate and on the side near the first clamping plate, and the first and second semicircles are rotatably connected.

[0011] In one possible implementation, one of the first semicircular body and the second semicircular body is provided with a mounting through hole, and the other is provided with a corresponding boss that mates with the mounting through hole.

[0012] In one possible implementation, the first semicircle and the second semicircle are rotatably connected by a pin, and a torsion spring is sleeved on the outside of the pin.

[0013] In one possible implementation, a first limiting groove is provided on the inner side of the first clamping plate, and a second limiting groove is provided on the inner side of the second clamping plate. The first limiting groove and the second limiting groove are respectively used to abut against the two ends of the torsion spring. A first limiting block is provided on the inner side of the first clamping plate, and a second limiting block is provided on the inner side of the second clamping plate. The first limiting block and the second limiting block are used to restrict the movement of the torsion spring.

[0014] In one possible implementation, the support channel includes a first support channel and a second support channel. One end of the first support channel is connected to a first fixing member via a first connector, and the other end is connected to a first clamping plate via a first right-angle connector. One end of the second support channel is connected to the first fixing member via a second connector, and the other end is connected to the second clamping plate via a second right-angle connector.

[0015] In one possible implementation, the support channel includes a first support channel and a second support channel, both of which are corrugated pipes.

[0016] In one possible implementation, the first fixing element is specifically a suction cup.

[0017] Compared with the above-mentioned background technology, the present invention provides a dialysis tubing support device, comprising: a first fixing member and a second fixing member, one of which is connected to a dialysis device and the other is connected to a nursing bed. A support tube channel is provided between the first fixing member and the second fixing member. The support tube channel is a hollow tubular structure with a first port and a second port that are connected to each other at its two ends. One of the first port and the second port is used for the insertion of the dialysis tubing, and the other port is used for the exit of the dialysis tubing. The support tube channel is used to support the dialysis tubing inserted therein.

[0018] Specifically, the first and second fixing components of the support device are respectively fixed between the dialysis equipment and the nursing bed, and a support channel is provided between the two. The support channel is a hollow pipe with a first port and a second port at each end, one as the inlet and the other as the outlet. In this way, the dialysis tubing between the dialysis equipment and the nursing bed can pass through the inside of the support channel. The two ends of the support channel are fixed by the first and second fixing components, which can support the dialysis tubing and prevent the portion of the dialysis tubing between the dialysis equipment and the nursing bed from sagging due to gravity. This avoids pulling on the arterial and venous puncture needles, increasing the risk of needle dislodgement and the risk of bleeding at the connection between the arterial and venous tubing and the puncture needle.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0030] The purpose of this invention is to provide a support device for dialysis tubing, which can prevent the risk of blood loss caused by the dialysis tubing sagging due to gravity.

[0031] To achieve the above objectives, the present invention provides the following technical solution:

[0032] Please see Figures 1 to 3This embodiment provides a support device for dialysis tubing, including: a first fixing member 100 and a second fixing member 200, one of which is connected to a dialysis device and the other is connected to a nursing bed. A support tube is provided between the first fixing member 100 and the second fixing member 200. The support tube is a hollow tubular structure with a first port 310 and a second port 320 that are connected to each other at both ends. One of the first port 310 and the second port 320 is used for the insertion of the dialysis tubing, and the other is used for the exit of the dialysis tubing. The support tube is used to support the dialysis tubing inserted therein.

[0033] Specifically, the first fixing member 100 and the second fixing member 200 in this embodiment can be adjusted appropriately according to actual needs, as long as they can be fixed to the dialysis equipment or nursing bed.

[0034] In this embodiment, the supporting tube acts as a bridge for the dialysis tubing. After its two ends are fixed by the first fixing member 100 and the second fixing member 200, its middle part needs to support the weight of the dialysis tubing. However, it should be noted that the number of the first fixing member 100 and the second fixing member 200, as well as the diameter and number of the supporting tube, need to be adjusted according to the actual situation. For example, if there are multiple dialysis tubing, a corresponding number of supporting tubes can be set, or a supporting tube with a larger diameter can be selected. However, in any case, the length of the supporting tube should match the distance between the dialysis equipment and the patient care bed.

[0035] In addition, the two ends of the support channel are respectively provided with a first port 310 and a second port 320, both of which are connected to the interior of the support channel. In other words, the first port 310 and the second port 320 are the entrance and exit of the support channel. In this embodiment, the first port 310 is the entrance and the second port 320 is the exit. The shape and size of the first port 310 and the second port 320 can be adjusted according to actual needs and are not specifically limited in this article.

[0036] In summary, the first fixing member 100 and the second fixing member 200 of the support device are respectively fixed between the dialysis equipment and the nursing bed, and a support channel is provided between the two. The support channel is a hollow pipe with a first port 310 and a second port 320 at its two ends, one as an inlet and the other as an outlet. In this way, the dialysis tubing between the dialysis equipment and the nursing bed can pass through the inside of the support channel. The two ends of the support channel are fixed by the first fixing member 100 and the second fixing member 200, which can support the dialysis tubing and prevent the part of the dialysis tubing between the dialysis equipment and the nursing bed from sagging due to gravity. This avoids pulling on the arterial and venous puncture needle, increasing the risk of needle dislodgement and the risk of bleeding at the connection between the arterial and venous tubing and the puncture needle.

[0037] In one possible implementation, the second fastener 200 includes a first clamping plate 210 and a second clamping plate 220 that are rotatably connected. A torsion spring 230 is provided between the first clamping plate 210 and the second clamping plate 220. The torsion spring 230 is used to drive the first clamping plate 210 and the second clamping plate 220 to clamp to the nursing bed or dialysis equipment.

[0038] In this embodiment, the second fixing member 200 is preferably a clip-shaped structure, which includes two clamping plates that can rotate relative to each other, and the first clamping plate 210 and the second clamping plate 220 are also fixed with torsion springs 230 so that the second fixing member 200 can be stably fixed to the bed frame or guardrail of the nursing bed for supporting the entire support structure.

[0039] Furthermore, the first clamping plate 210 and the second clamping plate 220 are provided with a clamping part 240 with a semi-circular structure at the end opposite to the bearing channel.

[0040] In order to adapt to the bed frame or guardrail of the nursing bed, in this embodiment, a semi-circular clamping part 240 is provided at the left end of the first clamping plate 210 and the second clamping plate 220. The clamping part 240 fits exactly with the bed frame or guardrail of the nursing bed, which has a circular cross section, thereby ensuring the stability of the second fixing member 200.

[0041] In one possible implementation, two first semicircular bodies 211 are provided in the middle of the first clamping plate 210 and on the side near the second clamping plate 220, and two second semicircular bodies 221 are provided in the middle of the second clamping plate 220 and on the side near the first clamping plate 210. The first semicircular bodies 211 and the second semicircular bodies 221 are rotatably connected. In this embodiment, the second semicircular bodies 221 are located inside the first semicircular bodies 211. Of course, in actual production, the first semicircular bodies 211 can also be located inside the second semicircular bodies 221, or the two first semicircular bodies 211 can be located on the same side of the two second semicircular bodies 221. This is not specifically limited here.

[0042] In this embodiment, a semi-circular first semi-circular body 211 is provided on the lower side of the middle position of the first clamping plate 210 at its two edges. Similarly, a semi-circular second semi-circular body 221 is provided on the upper side of the middle position of the second clamping plate 220 at its two edges. The width between the two second semi-circular bodies 221 is slightly smaller than the width between the two first semi-circular bodies 211. The pivot axis of the first clamping plate 210 and the second clamping plate 220 is located at the overlap of the first semi-circular body 211 and the second semi-circular body 221. In this embodiment, the torsion spring 230 is also installed on the inner side of the semi-circular body.

[0043] In one possible implementation, one of the first semicircular body 211 and the second semicircular body 221 is provided with a mounting through hole 212, and the other is provided with a boss 222 that mates with the mounting through hole 212.

[0044] Understandably, in one embodiment, a mounting through hole 212 can be provided on the first semicircular body 211, and correspondingly, a boss 222 that can be installed into the mounting through hole 212 is provided on the outer side of the second semicircular body 221, so that the relative rotation of the first clamping plate 210 and the second clamping plate 220 can be realized.

[0045] Of course, it is also possible to set a boss 222 on the first semicircle 211 and a mounting through hole 212 on the second semicircle 221; or set mounting through holes 212 and bosses 222 on the two first semicircles 211 respectively, and set bosses 222 and mounting through holes 212 on the two corresponding second semicircles 221 respectively. All these settings can achieve the rotation effect, so this article does not make specific limitations here.

[0046] In one possible implementation, the first semicircular body 211 and the second semicircular body 221 are rotatably connected by a pin, and the torsion spring 230 is sleeved on the outside of the pin.

[0047] In another embodiment, a pin can be inserted at the overlap of the first semicircle 211 and the second semicircle 221 to realize the relative rotation of the first clamping plate 210 and the second clamping plate 220. This arrangement also facilitates the fixing of the torsion spring 230, which can be sleeved on the outside of the pin.

[0048] In one possible implementation, a first limiting groove 213 is provided on the inner side of the first clamping plate 210, and a second limiting groove 223 is provided on the inner side of the second clamping plate 220. The first limiting groove 213 and the second limiting groove 223 are respectively used to abut against the two ends of the torsion spring 230. A first limiting block 214 is provided on the inner side of the first clamping plate 210, and a second limiting block 224 is provided on the inner side of the second clamping plate 220. The first limiting block 214 and the second limiting block 224 are used to restrict the movement of the torsion spring 230.

[0049] In this embodiment, in order to better limit the torsion spring 230 and prevent it from shifting its position, a first limiting groove 213 and a second limiting groove 223 are respectively provided on the inner side of the first clamping plate 210 and the second clamping plate 220. The two grooves abut against one end of the torsion spring 230. In addition, a first limiting block 214 and a second limiting block 224 are also provided to limit the torsion spring 230 from displacement perpendicular to the rotation axis.

[0050] In one possible implementation, the support channel includes a first support channel 330 and a second support channel 340. One end of the first support channel 330 is connected to the first fixing member 100 via a first connector 331, and the other end is connected to the first clamping plate 210 via a first right-angle connector 332. One end of the second support channel 340 is connected to the first fixing member 100 via a second connector 341, and the other end is connected to the second clamping plate 220 via a second right-angle connector 342.

[0051] In this embodiment, there are two dialysis lines, namely an arterial line and a venous line. The patient's blood is drawn out from the arterial puncture needle and flows into the arterial line, and then enters the dialysis device for purification. The purified blood flows from the venous line to the venous puncture needle, and is then returned to the patient's body. Correspondingly, in this embodiment, two support channels are provided in the first fixing member 100 and the second fixing member 200, namely the first support channel 330 and the second support channel 340, and a dialysis line is independently installed in each support channel.

[0052] Both the first port 310 and the second port 320 at both ends of the first support channel 330 and the second support channel 340 extend to the outer side to facilitate the insertion of the dialysis tubing. In this embodiment, the right end of the first support channel 330 is connected to the first connector 331, which is used to fix the corrugated tube. The first connector 331 is connected to the corrugated tube by snap-fit ​​or adhesive. The first connector 331 is also integrated with the suction cup. The left end of the first support channel 330 is fixedly connected to the first right-angle connector 332 by snap-fit. The other end of the first right-angle connector 332 is fixedly connected to the first connector 333, which is located at the upper end of the first clamping plate 210. The first connector 333 is also integrated with the first clamping plate 210. Similarly, the right end of the second support channel 340 is connected to the second connector 341, which is used to fix the corrugated pipe. The second connector 341 is connected to the corrugated pipe by snap-fit ​​or adhesive. At the same time, the second connector 341 and the suction cup are integrated into one structure. The left end of the second support channel 340 is fixedly connected to the second right-angle connector 342 by snap-fit. The other end of the second right-angle connector 342 is fixedly connected to the second connector 343. The second connector 343 is located at the upper end of the second clamping plate 220. The second connector 343 and the second clamping plate 220 are integrated into one structure.

[0053] In addition, the clamping part 240, the clamping plate and the semi-circular body are integrated into one structure, and the three can be integrally molded by injection molding.

[0054] In one possible implementation, both the first support channel 330 and the second support channel 340 are corrugated pipes.

[0055] Furthermore, in this embodiment, the first support channel 330 and the second support channel 340 are preferably corrugated pipes. A corrugated pipe is a tubular structure made of plastic material with a corrugated shape design. The corrugated structure gives the corrugated pipe excellent flexibility and adaptability, allowing it to adapt to different shapes and lengths without losing structural integrity. In addition, the material of the corrugated pipe is preferably a high molecular polymer such as polyethylene or polypropylene. Of course, other materials can be selected according to the actual situation, and no specific limitation is made here.

[0056] In one possible implementation, the first fixing member 100 is specifically a suction cup.

[0057] In this embodiment, the first fixing member 100 is preferably a circular suction cup. The suction cup is used to fix the supporting structure to the side panel of the dialysis device. Pressing the suction cup forcefully causes the air between the suction cup and the side panel of the dialysis device to be expelled. Under the action of external atmospheric pressure, the suction cup is firmly fixed to the side panel of the dialysis device. The suction cup is made of high molecular elastomers such as silicone and rubber.

[0058] In summary, this application provides a support device for dialysis tubing. By installing this support device between the dialysis equipment and the nursing bed, the excessively long portions of the arterial and venous tubing of the dialysis tubing are routed through the support channel of the support device. This avoids the risk of blood loss caused by tubing sagging due to gravity, and also avoids the problem of obstruction of the extracorporeal circulation system caused by tubing entanglement. This increases the safety of dialysis treatment, simplifies the operation of medical staff, and reduces their workload.

[0059] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model.
