Description

Technical Field

[0001] The present invention specifically relates to a dialysis pipeline fixing device. Background Art

[0002] In clinical practice, the dialysis pipeline is the lifeline during a patient's treatment. Clinically, most current dialysis pipelines are fixed to the hospital bed using objects such as tape, or fixed clamps are used for fixation. For example, the portable dialysis pipeline fixator disclosed in Chinese Patent Document CN213789209U and the bedside fixing bracket for hemodialysis pipelines disclosed in CN102526821B mainly use the structure of anti - detachment splints to clamp and fix the pipeline. Although the redundant pipelines are effectively accommodated and the pipeline is firmly clamped accordingly, if the dialysis machine, the patient himself, or other external factors accidentally pull the pipeline, there is still a relatively high risk of the pipeline becoming disconnected or causing secondary harm to the patient. Therefore, it is not sufficient to meet the further requirements for convenient, safe fixation and anti - pulling use of the dialysis pipeline. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a dialysis pipeline fixing device that can prevent the dialysis pipeline from getting chaotic and can prevent the pipeline from falling off due to being pulled within a certain range.

[0004] To achieve the above - mentioned purpose, the present invention is realized through the following technical solutions: A dialysis pipeline fixing device includes:

[0005] A bottom plate that can be fixed to a dialysis machine or a bed body, and a center line is arranged along the length direction of the bottom plate;

[0006] A plurality of wire winding members are arranged at intervals along the length direction of the bottom plate. Each wire winding member includes a fixing member, an elastic telescopic member, and a wire clamping member. The fixing member is fixed to the bottom plate. The elastic telescopic member is arranged perpendicular to the center line. One end of the elastic telescopic member is fixed to the fixing member, and the other end of the elastic telescopic member is fixed with the wire clamping member. The fixing member and the wire clamping member located on the same side of the center line are arranged at intervals. The wire clamping member is used to hold the dialysis pipeline tightly, and the dialysis pipeline can slide through all the wire clamping members in sequence.

[0007] Furthermore, a plurality of guiding grooves are opened along the width direction of the bottom plate. The guiding grooves correspond to the wire clamping members one by one, and the bottom end of the wire clamping member can slide and be clamped in the guiding groove.

[0008] Furthermore, a limiting hole is arranged at the top of each guiding groove, and all the limiting holes are located directly below the center line. The bottom of the wire clamping member can be clamped and locked in the limiting hole.

[0009] Furthermore, it further includes an unlocking member, and the connection of the unlocking member to all the wire clamping members can simultaneously drive the bottoms of all the wire clamping members to disengage from the limiting holes.

[0010] Furthermore, an installation hole communicating with all the limiting holes is provided on one side of the bottom plate far from the wire winding member. The unlocking member includes a driving source and a top plate. The driving source is installed in the installation hole. There are multiple top plates, and the multiple top plates are arranged on the driving source at intervals and correspond to the limiting holes one by one. The driving source can drive the tops of the top plates to extend into the limiting holes to lift the tops and bottoms of the wire clamping members until the bottoms of the wire clamping members disengage from the limiting holes.

[0011] Furthermore, the driving source includes a connecting plate, two screw rods and a rotary driving member. The connecting plate can slide up and down in the installation hole. All the top plates are arranged on the connecting plate. The two screw rods are rotatably installed at both ends of the bottom plate and are respectively threadedly connected to both ends of the connecting plate. The rotary driving member is connected to the two screw rods and can simultaneously drive the two screw rods to rotate forward or backward, thereby driving the connecting plate to move up or down.

[0012] Furthermore, the wire clamping member includes a support member, a limiting plate and an angle locking member. The support member is fixed on the bottom plate. The limiting plate is hinged to the top of the support member and can rotate around an axis parallel to the center line. The angle locking member is connected between the support member and the limiting plate and is used to lock and fix the angle between the support member and the limiting plate.

[0013] Furthermore, the angle locking member includes a central shaft and a locking screw. The central shaft is rotatably connected to the top end of the support member. The end of the limiting plate is fixedly connected to the central shaft. The locking screw is arranged on the limiting plate. By rotating the locking screw, the end of the locking screw can be pressed against the central shaft.

[0014] Furthermore, the support member is a cylinder, and a freely rotatable sleeve is sleeved on the support member.

[0015] Advantages of the present invention:

[0016] When the above dialysis tubing fixing device is used, the dialysis tubing is sequentially passed through all the wire clamping members and finally exits from the side far from the dialysis machine. The dialysis tubing forms a wavy shape on the fixing device under the guiding and limiting of all the wire clamping members, so that the dialysis tubing forms a horizontal stacked state on the fixing device. When the pipeline is pulled, under the action of the pulling force, the wire clamping members are forced to approach the center line direction, and the elastic telescopic member contracts to supplement the length of the stacked pipeline that needs to be pulled.

[0017] Using this fixing device can prevent the dialysis pipeline from getting chaotic. At the same time, when the dialysis pipeline is pulled, it can provide a certain additional length and prevent the pipeline from detaching due to being pulled within a certain range.

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Please refer to Figures 1 to 5 , the present invention provides a dialysis pipeline fixing device, which includes a bottom plate 100 and a wire winding member 200.

[0029] Specifically, the bottom plate 100 can be fixed on a dialysis machine or a bed body. In a specific implementation, the fixing method of the bottom plate 100 and the dialysis member can be fixing methods such as bonding, clamping, bundling or magnetic connection. A center line is arranged along the length direction of the bottom plate 100.

[0030] There are multiple wire winding members 200, and the multiple wire winding members 200 are arranged at intervals along the length direction of the bottom plate 100. Each wire winding member 200 includes a fixing member 210, an elastic telescopic member 220 and a wire clamping member 230. The fixing member 210 is fixed on the bottom plate 100, the elastic telescopic member 220 is arranged perpendicular to the center line, one end of the elastic telescopic member 220 is fixed on the fixing member 210, and the other end of the elastic telescopic member 220 is fixed with a wire clamping member 230, and the fixing member 210 and the wire clamping member 230 located on the same side of the center line are arranged at intervals. The wire clamping member 230 is used to tightly hold the dialysis pipeline 1, and the dialysis pipeline 1 can sequentially slide through all the wire clamping members 230.

[0031] When in use, the dialysis pipeline 1 sequentially passes through all the wire clamping members 230 and finally exits from the side far away from the dialysis machine. The dialysis pipeline 1 forms a wavy shape on the fixing device under the guiding and limiting of all the wire clamping members 230, so that the dialysis pipeline 1 forms a horizontal stacked state on the fixing device. When the pipeline is pulled, under the action of the pulling force, the wire clamping member 230 is forced to approach the center line direction, and the elastic telescopic member 220 contracts to supplement the length required for pulling the stacked pipelines.

[0032] Using this fixing device can not only prevent the dialysis pipeline 1 from being chaotic, but also, when the dialysis pipeline 1 is pulled, it can give a certain supplementary length and can prevent the pipeline from being separated due to being pulled within a certain range.

[0033] In a specific implementation, a plurality of guiding grooves 110 can be opened along the width direction of the bottom plate 100. The guiding grooves 110 correspond to the wire clamping members 230 one by one, and the bottom end of the wire clamping member 230 can be slidably clamped in the guiding grooves 110. Through the limiting of the guiding grooves 110, the wire clamping member 230 can be prevented from swaying left and right during the movement, affecting the expansion and contraction of the dialysis pipeline 1.

[0034] As a preferred implementation manner, a limiting hole 120 is arranged at the top of each guiding groove 110, and all the limiting holes 120 are located directly below the center line. The bottom of the wire clamping member 230 can be clamped and locked in the limiting hole 120.

[0035] Before threading the dialysis tube 1, all the wire clamping members 230 can be first moved towards the center line and clamped in the limiting holes 120. At this time, the dialysis tube 1 can be sequentially passed through all the wire clamping members 230 along the center line. Finally, the wire clamping members 230 are sequentially driven to disengage from the limiting holes 120. Under the action of the elastic telescopic member 220 and the guiding groove 110, some of the wire clamping members 230 approach the long side on one side of the bottom plate 100, and the remaining part approaches the long side on the other side of the bottom plate 100. While approaching, the wire is driven to move, so that the wire finally forms a horizontal stacked state, which is convenient for buffering when being pulled. By adopting this method, the efficiency of threading the dialysis tube 1 can be improved.

[0036] As a more preferred embodiment, the device further includes an unlocking member 300. The connection between the unlocking member 300 and all the wire clamping members 230 can simultaneously drive the bottoms of all the wire clamping members 230 to disengage from the limiting holes 120. The trouble of sequentially driving the wire clamping members 230 to disengage from the limiting holes 120 is avoided, thereby improving the working efficiency.

[0037] Specifically, an installation hole communicating with all the limiting holes 120 is provided on one side of the bottom plate 100 far from the wire winding member 200. The unlocking member 300 includes a driving source 310 and a top plate 320. The driving source 310 is installed in the installation hole. There are multiple top plates 320, and the multiple top plates 320 are arranged on the driving source 310 at intervals and correspond to the limiting holes 120 one by one. The driving source 310 can drive the top of the top plate 320 to penetrate into the limiting hole 120 to lift the top and bottom of the wire clamping member 230 until the bottom of the wire clamping member 230 disengages from the limiting hole 120.

[0038] During use, when the driving source 310 drives the connecting plate 311 to move downward, the bottom of the wire clamping member 230 can be clamped in the limiting groove. When the driving source 310 drives the connecting plate 311 to move upward to be flush with the bottom of the guiding groove 110, the wire clamping member 230 can be pushed out of the limiting hole 120, which is convenient for the wire clamping member 230 to slide along the guiding groove 110.

[0039] In this embodiment, the driving source 310 includes a connecting plate 311, two screw rods 312 and a rotary driving member 313. The connecting plate 311 is slidably arranged in the installation hole, and all the top plates 320 are arranged on the connecting plate 311. The two screw rods 312 are rotatably installed at both ends of the bottom plate 100 and are respectively threadedly connected to the two sides of the connecting plate 311. The rotary driving member 313 is connected to the two screw rods 312 and can simultaneously drive the two screw rods 312 to rotate forward or backward, thereby driving the connecting plate 311 to move up or down. The rotary driving member 313 can be two rotary motors connected electrically, or a belt drive structure, a chain drive structure, etc.

[0040] When the two screw rods 312 rotate forward or backward simultaneously, the connecting plate 311 can be driven to rise or fall.

[0041] In this embodiment, the wire clamping member 230 includes a support member 231, a limiting plate 232, and an angle locking member 233. The support member 231 is fixed on the bottom plate 100. The limiting plate 232 is hinged to the top of the support member 231 and can rotate around an axis parallel to the center line. The angle locking member 233 is connected between the support member 231 and the limiting plate 232 and is used to lock and fix the angle between the support member 231 and the limiting plate 232.

[0042] During use, first place the bottom of the wire clamping member 230 inside the limiting plate 232, then rotate the limiting plate 232 so that it is in the same plane as the support member 231, and fix the angle through the angle locking member 233. Then, along the center line, sequentially wind the dialysis pipeline 1 around the support member 231. Next, first unlock the first angle locking member 233, rotate the limiting plate 232 downward until it is parallel to the bottom plate 100, and then lock the limiting plate 232 with the angle locking member 233. Then unlock the second angle locking member 233, rotate the second limiting plate 232 downward in the opposite direction to the first limiting plate 232 until it is parallel to the bottom plate 100, and then lock the second limiting plate 232 with the second angle locking member 233. Then, operate the third wire clamping member 230 in the same manner as the first angle locking member 233, and operate the fourth wire clamping member 230 in the same manner as the second angle locking member 233, and so on until the wire clamping of all the wire clamping members 230 is completed.

[0043] In this way, through the limitation of the limiting plate 232, it is possible to prevent the pipeline from detaching from the wire clamping member 230 during use. At the same time, by using the limiting plate 232 with adjustable angle, it is convenient to fix the pipeline.

[0044] In this embodiment, the angle locking member 233 includes a central shaft 2331 and a locking screw 2332. The central shaft 2331 is rotatably connected to the support member 231, the end of the limiting plate 232 is fixedly connected to the central shaft 2331, the locking screw 2332 is arranged on the limiting plate 232, and by rotating the locking screw 2332, the end of the locking screw 2332 can be pressed against the central shaft 2331.

[0045] When it is necessary to rotate the limiting plate 232, first loosen the locking screw 2332, and after the angle of the limiting plate 232 is adjusted, it can be done through the locking screw 2332.

[0046] In addition, during specific implementation, the fixing member 210 can also be set as a cylinder, and a freely rotatable sleeve is sleeved on the fixing member 210. The sleeve can reduce the friction between the pipeline and the fixing member 210 and facilitate circular sliding.

[0047] Using this fixing device can prevent the dialysis pipeline 1 from being disordered. At the same time, it can give a certain additional length when the dialysis pipeline 1 is pulled by another force, and can prevent the pipeline from being pulled off due to being pulled within a certain range.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
