Description

Technical Field

[0001] The utility model relates to the technical field of blood dialysis pipeline fixing, in particular to a pipeline fixing structure. Background Technique

[0002] Blood dialysis pipelines are crucial components in blood dialysis treatment. They are responsible for drawing blood out of the body, purifying it through a dialyzer, and then returning it to the body. Depending on the usage method and treatment requirements, blood dialysis pipelines can be divided into various types. The number of cannulas in blood dialysis mainly depends on the type of vascular access used. Blood dialysis mainly uses an external dialyzer to purify blood. An arteriovenous fistula is established through surgery, and a syringe needle is inserted during treatment. Usually, two syringe needles are required: one for drawing blood out of the body for purification, and the other for injecting the purified blood back into the body.

[0003] Considering the movement space of the patient's arm, blood dialysis tubes are generally designed to be relatively long, but there is a lack of a pipeline fixing structure. The extended part of the pipeline will hang between the dialysis equipment and the patient. When nursing the patient, it is easy to accidentally touch and pull the pipeline, thus pulling one end of the dialysis equipment or the end connected to the patient, which is very unsafe.

[0004] To solve the above problems, a pipeline fixing structure is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pipeline fixing structure to solve the problem that blood dialysis pipelines are generally designed to be relatively long, but there is a lack of a pipeline fixing structure. The extended part of the pipeline will hang between the dialysis equipment and the patient. When nursing the patient, it is easy to accidentally touch and pull the pipeline, thus pulling one end of the dialysis equipment or the end connected to the patient, which is very unsafe as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A pipeline fixing structure, including a support plate and a telescopic rod. A protective frame is fixedly installed on the top of the support plate. Two rollers are rotatably connected inside the protective frame. The dialysis pipeline passes through the gap between the two rollers and is connected to the patient's blood vessel. The top of the telescopic rod is fixedly installed with a transverse plate. A support frame is installed on the transverse plate. A screw rod is threadedly connected to the support frame. One end of the screw rod is rotatably connected to an arc-shaped clamping plate. When the arc-shaped clamping plate moves towards the side of the transverse plate, it can clamp the dialysis pipeline on the side of the transverse plate.

[0007] Preferably, mounting sleeves are fixedly installed at the bottoms of the support plate and the telescopic rod. The mounting sleeves can be sleeved on the guardrail of the hospital bed and fixed to the hospital bed guardrail by tightening bolts.

[0008] Preferably, a rectangular through groove is formed between the top and bottom of the protection frame, and two circular hole grooves are symmetrically formed on both inner sides of the rectangular through groove. Round rods are installed at both ends of the roller and are rotatably connected to the circular hole grooves.

[0009] Preferably, annular grooves are formed at the length centers of the rollers, and the dialysis pipeline passes through the inner sides of the annular grooves on the two rollers. The gap length between the inner side surfaces of the two annular grooves is smaller than the cross-sectional diameter of the dialysis pipeline.

[0010] Preferably, a manual bolt is installed on one side of the top of the telescopic rod fixed section, and the manual bolt extends into the fixed section and can squeeze against the outer side surface of the telescopic section.

[0011] Preferably, a clamping groove is formed on the side surface of the transverse plate close to the arc-shaped clamping plate. When the arc-shaped clamping plate moves, the dialysis pipeline is clamped inside the clamping groove.

[0012] Preferably, a threaded hole is formed between the center of the inner side surface and the outer side surface of the support frame. The screw rod is in threaded connection with the threaded hole. One end of the screw rod extends into the inner side of the support frame by rotating clockwise and is rotatably connected to one end of the arc-shaped clamping plate.

[0013] Preferably, a nut is fixedly installed at one end of the screw rod outside the support frame. When rotating the screw rod through the nut, one hand needs to hold the arc-shaped clamping plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, one end of the dialysis pipeline passes through the inner side of the arc-shaped clamping plate. By rotating the screw rod, the arc-shaped clamping plate can be driven to move, and the dialysis pipeline can be clamped and fixed on one side surface of the transverse plate. Thus, when the pipeline is pulled, it will not involve the end connected to the patient. After one end of the dialysis pipeline passes through the arc-shaped clamping plate and then through the gap between the two rollers, during the movement of the patient's arm, the pipeline is retracted and released by the rotation of the two rollers. Therefore, the long part of the pipeline can be controlled between the protection frame and the arc-shaped clamping plate, preventing the pipeline from being messy and facilitating the retraction and release of the pipeline.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Embodiment:

[0023] Please refer to Figures 1-4 , this embodiment provides a pipeline fixing structure, including a support plate 2 and a telescopic rod 4. A protective frame 3 is fixedly installed on the top of the support plate 2. Two rollers 31 are rotatably connected inside the protective frame 3. The dialysis pipeline passes through the gap between the two rollers 31 and is connected to the patient's blood vessel. A transverse plate 5 is fixedly installed on the top of the telescopic rod 4. A support frame 6 is installed on the transverse plate 5. A screw 62 is threadedly connected to the support frame 6. One end of the screw 62 is rotatably connected to an arc-shaped clamping plate 63. When the arc-shaped clamping plate 63 moves towards the side of the transverse plate 5, the dialysis pipeline can be clamped on the side surface of the transverse plate 5. During the use of this pipeline fixing structure, by passing one end of the dialysis pipeline through the inside of the arc-shaped clamping plate 63, the rotation of the screw 62 can drive the movement of the arc-shaped clamping plate 63, and the dialysis pipeline can be clamped on one side surface of the transverse plate 5 for fixation. Thus, when the pipeline is pulled, it will not affect the end connected to the patient. After one end of the dialysis pipeline passes through the arc-shaped clamping plate 63 and then through the gap between the two rollers 31, during the movement of the patient's arm, the pipeline is wound and unwound through the rotation of the two rollers 31. Therefore, the long part of the pipeline can be controlled between the protective frame 3 and the arc-shaped clamping plate 63, preventing the pipeline from being messy and facilitating the winding and unwinding of the pipeline.

[0024] In this embodiment, as Figure 1 shown, installation sleeves 1 are fixedly installed at the bottoms of the support plate 2 and the telescopic rod 4. The installation sleeves 1 can be sleeved on the guardrail of the hospital bed and fixed to the hospital bed guardrail by tightening with bolts. Therefore, the installation and disassembly of this pipeline fixing structure are relatively convenient and can be selectively installed.

[0025] In this embodiment, as Figure 1 andFigure 4 As shown, a rectangular through - slot is provided between the top and bottom of the protective frame 3. On both inner sides of the rectangular through - slot, two circular hole slots are symmetrically provided. Circular rods are installed at both ends of the roller 31 and are rotatably connected to the circular hole slots. Therefore, the roller 31 can rotate inside the protective frame 3.

[0026] In this embodiment, as Figure 1 and Figure 4 shown, annular grooves 32 are provided at the length centers of the rollers 31. The dialysis pipeline passes through the inner sides of the annular grooves 32 on the two rollers 31. The gap length between the inner side surfaces of the two annular grooves 32 is less than the cross - sectional diameter of the dialysis pipeline. Thus, the pipeline is clamped and rotates inside the annular groove 32. When the pipeline is pulled in a certain direction, the roller 31 rotates in that direction, facilitating the retraction and release of the pipeline.

[0027] In this embodiment, as Figure 1 and Figure 2 shown, a manual bolt is installed on one side of the top of the fixed section of the telescopic rod 4, and the manual bolt extends into the fixed section and can press against the outer side surface of the telescopic section. At this time, the length of the telescopic rod 4 can be adjusted and fixed by the manual bolt, and the pipeline can be lifted to avoid accidental collision due to too low pendency.

[0028] In this embodiment, as Figure 1 and Figure 2 shown, a card slot 51 is provided on the side surface of the transverse plate 5 close to the arc - shaped clamping plate 63. When the arc - shaped clamping plate 63 moves, the dialysis pipeline is clamped inside the card slot 51, avoiding excessive deformation of the dialysis pipeline caused by extrusion and affecting the blood flow rate of dialysis.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a threaded hole 61 is provided between the center of the inner side surface and the outer side surface of the support frame 6. The screw 62 is in threaded connection with the threaded hole 61. One end of the screw 62 extends to the inside of the support frame 6 by clockwise rotation and is rotatably connected to one end of the arc - shaped clamping plate 63. A nut is fixedly installed at the end of the screw 62 outside the support frame 6. When rotating the screw 62 through the nut, one hand needs to hold the arc - shaped clamping plate 63. At this time, the arc - shaped clamping plate 63 can move smoothly towards the direction of the card slot 51, avoiding its simultaneous rotation with the screw 62.

[0030] Working principle: When the pipeline fixing structure is in use, first pass one end of the dialysis pipeline through the inner side of the arc-shaped clamping plate 63, and reserve an appropriate length below the transverse plate 5. Then, when rotating the screw rod 62 with a nut, one hand needs to hold the arc-shaped clamping plate 63. At this time, the arc-shaped clamping plate 63 can smoothly move towards the clamping groove 51 to clamp the dialysis pipeline. Thus, when the pipeline is pulled, it will not affect the end connected to the patient. In addition, after the dialysis pipeline is clamped by the arc-shaped clamping plate 63, the end below the transverse plate 5 passes through the inner side of the annular grooves 32 on the two rollers 31. The gap length between the inner side surfaces of the two annular grooves 32 is less than the cross-sectional diameter of the dialysis pipeline. Thus, the pipeline is clamped and can rotate inside the annular groove 32. When the pipeline is pulled in any direction, the roller 31 will rotate in that direction, and the winding and unwinding of the pipeline will not cause the pipeline to be messy.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
