Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical device auxiliary equipment, and specifically refers to a blood dialysis pipeline anti-falling device, which is used to effectively fix the blood dialysis pipeline during hemodialysis, prevent the pipeline from accidentally falling, and ensure the smooth progress of hemodialysis treatment. Background Art
[0002] Hemodialysis is one of the important means for treating patients with end-stage renal disease. The patient's blood is drawn out of the body, purified by a dialyzer, and then transfused back into the body. In this process, the blood dialysis pipeline plays a crucial connecting role, connecting devices such as the patient's blood vessels, dialysis machine, and dialyzer. However, currently, during hemodialysis, there are many hidden dangers in the fixation of the blood dialysis pipeline.
[0003] The existing fixation methods for blood dialysis pipelines are relatively simple and traditional. Some hospitals only rely on medical adhesive tape to paste the pipeline on the patient's skin or fix it on the edge of the hospital bed. This method not only has poor fixation effect, but also the pipeline is extremely easy to loosen and fall off due to external force pulling during the patient's movement or medical staff's operation. Once the blood dialysis pipeline falls off, on the one hand, it will cause blood to flow out, not only wasting medical resources, but also possibly causing serious consequences such as patient infection; on the other hand, it will force the dialysis treatment to be interrupted, affecting the treatment effect, and even endangering the patient's life safety.
[0004] In addition, the fixation devices used in some hospitals are not reasonably designed. For example, simple clips are used to fix the pipeline, but the clips are easy to cause local compression on the pipeline, affecting blood flow, and the fixing positions of the clips are relatively single, unable to adapt to the actual needs of different layouts of hemodialysis equipment and patients. There are also some fixation devices that are inconvenient to install and disassemble. Medical staff need to spend more time and energy to adjust the fixation state of the pipeline during the operation, which to a certain extent reduces the medical work efficiency.
[0005] In summary, it is of great practical significance to develop an anti-falling device that can reliably fix the blood dialysis pipeline, avoid the pipeline from falling, is convenient for medical staff to operate, and does not cause adverse effects on the pipeline. Summary of the Invention
[0006] The present invention aims to solve the above technical problems and provides a blood dialysis pipeline anti-falling device.
[0007] To solve the above technical problems, the technical solution provided by the present invention is: a blood dialysis pipeline anti-falling device, comprising:
[0008] A fixator, which is arranged on the planes of bedside tables, hospital beds, and hemodialysis instruments, and specifically includes a chute and a fixing plate;
[0009] A sliding plate is slidably arranged on a fixture. An installation plate is provided on the sliding plate, and a plurality of installation holes are provided on the installation plate;
[0010] The fixture is arranged in the installation hole and specifically includes a conical body. A groove plate for fixing a pipeline is provided on the conical body.
[0011] Furthermore, the cross-sections of the sliding groove and the installation plate are both T-shaped structures that cooperate with each other, and baffles for preventing detachment are provided at both ends of the installation plate.
[0012] Furthermore, a threaded shaft is provided on the fixing plate. One end of the threaded shaft is provided with a knob and the other end is provided with a negative pressure block. The negative pressure block is a cavity structure and is made of rubber material. By pressing with the knob, the negative pressure state between the negative pressure block and the plane is achieved to complete the pressing.
[0013] Furthermore, both ends of the installation plate are connected to the installation plate through support feet, and the height of the support feet is greater than the height of the conical body.
[0014] Furthermore, a plurality of sector plates are provided in the installation hole, and the plurality of sector plates are distributed in a circumferential shape;
[0015] The sector plates are made of elastic material, and the elasticity of a section close to the installation hole is less than the elasticity of the other tip.
[0016] Furthermore, an annular groove is provided on the conical body, and the width of the groove is the same as the width of the sector plate.
[0017] Furthermore, a plurality of fixing grooves are provided on the groove plate, and the plurality of fixing grooves are distributed horizontally or vertically to form interconnected grooves. Elastic plates are symmetrically provided in the grooves.
[0018] Furthermore, the elastic plates are arc-shaped structures and are arranged back to back. The upper ends of the elastic plates are fixedly connected to the grooves, and the bottoms do not contact the grooves.
[0019] The advantages of the present invention compared with the prior art are as follows:
[0020] 1. The fixing effect is reliable
[0021] The fixture forms a negative pressure adsorption with the plane through the negative pressure block, and can withstand a large external pulling force, ensuring that the entire device will not move easily during use.
[0022] The special cooperation structure between the fixing head and the installation hole, that is, the tight engagement between the sector plate 203 and the conical body groove 3011, and the clamping effect of the elastic plate in the groove plate on the pipeline, enable the hemodialysis pipeline to be firmly fixed, effectively avoiding the risk of the pipeline falling off due to external force, and ensuring the safety and continuity of hemodialysis treatment.
[0023] 2. Strong adaptability
[0024] The sliding plate can slide freely on the chute of the fixator and can be flexibly adjusted to a fixed position according to the layout of different hemodialysis devices, the position of the hospital bed, and the actual needs of patients, so as to adapt to a variety of usage scenarios.
[0025] The fixing grooves are distributed horizontally or vertically and are interconnected, which can meet the fixing requirements of hemodialysis tubes with different orientations and specifications, and improve the versatility of the device.
[0026] 3. Protect the tube
[0027] The height design of the support feet ensures that the tube will not come into direct contact with the sliding plate, reducing the friction and compression on the tube.
[0028] The elastic plate adopts an arc-shaped structure and is arranged in the opposite direction. The clamping force on the tube is moderate and will not cause local over-compression on the tube, so as not to affect the normal flow of blood in the tube and extend the service life of the tube.
[0029] 4. Convenient operation
[0030] The fixator can be fixed and disassembled by rotating the knob, and the operation is simple and fast, which is convenient for medical staff to quickly install and adjust the device in different scenarios.
[0031] The plug-in installation method of the fixing head and the automatic clamping function of the elastic plate on the tube enable medical staff to avoid complex operation steps when fixing the hemodialysis tube, improving the medical work efficiency. Brief description of the drawings

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0038] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; for those of ordinary skill in the art, the specific meaning of the above terms in the present invention can be understood according to specific situations.
[0039] I. Working principle of the present invention:
[0040] The hemodialysis pipeline anti-falling device mainly includes a fixator 1, a sliding plate 2 and a fixing head 3.
[0041] Fixator 1
[0042] The fixator is arranged on the planes such as bedside tables, hospital beds, hemodialysis instruments, etc., and is composed of a chute 101 and a fixing plate 102. The cross-sections of the chute 101 and the mounting plate 201 are both T-shaped structures that cooperate with each other. This design enables the sliding plate 2 to slide stably on the fixator 1, while restricting the displacement of the sliding plate 2 in the horizontal direction, ensuring that it will not shift randomly during use. The two ends of the mounting plate 201 are provided with baffles to prevent falling off, further enhancing the stability of the connection between the sliding plate 2 and the fixator 1 and preventing the sliding plate 2 from accidentally coming out of the chute 101.
[0043] The fixing plate 102 is provided with a threaded shaft 103, and one end of the threaded shaft 103 is provided with a knob 104, and the other end is provided with a negative pressure block 105. The negative pressure block 105 is a cavity structure and is made of rubber material. When it is necessary to fix the fixator 1 on the plane, by rotating the knob 104, the threaded shaft 103 is pushed to make the negative pressure block 105 contact and press against the plane. Due to the good elasticity and sealing performance of the rubber material of the negative pressure block 105, during the pressing process, the air in its internal cavity is extruded to form a negative pressure state, so as to tightly adsorb on the plane and realize the firm connection between the fixator 1 and the plane.
[0044] Sliding plate 2
[0045] The sliding plate 2 is slidably arranged on the fixator 1. An installation plate 201 is provided on the sliding plate 2, and a plurality of installation holes 202 are provided on the installation plate 201. Both ends of the installation plate 201 are connected to the sliding plate 2 through support feet 203, and the height of the support feet 203 is greater than the height of the conical body 301. Such a design makes the overall height of the fixing head 3 lower than that of the support feet 203 after the fixing head 3 is installed in the installation hole 202, ensuring that when fixing the hemodialysis pipeline, the pipeline will not be subject to unnecessary friction or compression due to direct contact with the sliding plate 2, and at the same time providing a reasonable spatial layout for the fixing of the pipeline. In addition, a plurality of sector plates 203 are provided in the installation hole 202, and the plurality of sector plates 203 are distributed in a circular shape. The sector plates 203 are made of elastic materials, and the elasticity of one end close to the installation hole 202 is less than that of the other tip.
[0046] Fixing head 3
[0047] The fixing head 3 is arranged in the installation hole 202 and is composed of a conical body 301 and a groove plate 302 for fixing the pipeline. An annular groove 3011 is provided on the conical body 301, and the width of the groove 3011 is the same as the width of the sector plate 203. When the fixing head 3 is inserted into the installation hole 202, the tip part of the sector plate 203 will open outwards due to the insertion of the conical body 301, and use its elasticity to tightly clamp the groove 3011 of the conical body 301, thereby realizing the stable installation of the fixing head 3 in the installation hole 202.
[0048] A plurality of fixing grooves 303 are provided on the groove plate 302, and the plurality of fixing grooves 303 are distributed horizontally or vertically to form interconnected grooves. Elastic plates 304 are symmetrically provided in the grooves. The elastic plates 304 are arc-shaped structures and are arranged back to back. The upper ends of the elastic plates 304 are fixedly connected to the grooves, and the bottoms do not contact the grooves. This design enables the elastic plates 304 to moderately clamp the pipeline by using their elasticity when the hemodialysis pipeline is placed in the fixing grooves 303, ensuring both the stability of the pipeline fixing and not causing excessive compression on the pipeline to affect blood circulation.
[0049] When using this hemodialysis pipeline anti-falling device, first, according to the actual usage scenario, place the fixator 1 on a suitable plane, such as the flat part of a bedside table, a hospital bed, or a hemodialysis instrument. By rotating the knob 104, the negative pressure block 105 is brought into close contact with the plane to form negative pressure adsorption, thereby firmly fixing the fixator 1 on the plane.
[0050] Then, according to the layout and fixing requirements of the hemodialysis pipeline, slide the sliding plate 2 so that it moves to a suitable position on the sliding groove 101 of the fixator 1.
[0051] Next, insert the fixed head 3 into the mounting hole 202 of the mounting plate 201. Utilize the cooperation between the sector plate 203 and the groove 3011 of the conical body 301 to stably install the fixed head 3. Specifically, when the conical body 301 of the fixed head 3 is inserted into the mounting hole 202, the sector plate 203 is squeezed, and its tip opens outward. As the conical body 301 further penetrates, the tip of the sector plate 203 enters the groove 3011, and it uses its own elasticity to clamp the groove, realizing the fixation of the fixed head 3.
[0052] Finally, place the hemodialysis tubing in the fixing groove 303 of the groove plate 302 of the fixed head 3. The elastic plate 304 will undergo elastic deformation due to the placement of the tubing, clamping and fixing the tubing to ensure that the hemodialysis tubing does not fall off during dialysis.
[0053] II. Detailed implementation method:
[0054] Example 1: Use beside the hospital bed
[0055] Install the fixator
[0056] Select a suitable flat position beside the hospital bed, such as the side rail of the hospital bed or the surface of the bedside table. Place the fixator 1 on this plane, ensuring that the fixing plate 102 is in full contact with the plane.
[0057] Slowly rotate the knob 104 so that the threaded shaft 103 pushes the negative pressure block 105 gradually closer to the plane. When the negative pressure block 105 contacts the plane, continue to rotate the knob 104 until an obvious resistance is felt. At this time, the negative pressure block 105 has formed a negative pressure adsorption with the plane, and the fixator 1 is firmly fixed on the plane.
[0058] Adjust the position of the sliding plate
[0059] According to the position where the hemodialysis tubing exits from the patient's body and the spatial layout around the hospital bed, slide the sliding plate 2 along the sliding groove 101 of the fixator 1 so that the mounting plate 201 on the sliding plate 2 moves to a position convenient for fixing the hemodialysis tubing.
[0060] Install the fixed head
[0061] Select an appropriate number of fixed heads 3, align the conical body 301 with the mounting hole 202 on the mounting plate 201, and gently insert it. As the conical body 301 is inserted, the sector plate 203 in the mounting hole 202 will open outward due to elasticity. When the tip part of the sector plate 203 enters the groove 3011 of the conical body 301, the sector plate 203 will recover part of its elasticity and tightly clamp the groove 3011, thereby stably installing the fixed head 3 in the mounting hole 202.
[0062] Fix the hemodialysis tubing
[0063] The hemodialysis tubing is placed in the fixing groove 303 of the groove plate 302 of the fixing head 3 according to its direction. When the tubing is placed in the fixing groove 303, the elastic plates 304 symmetrically arranged in the groove will produce elastic deformation due to the extrusion of the tubing, clamping the tubing from both sides, so that the tubing is firmly fixed in the fixing groove 303.
[0064] Example 2: Use next to a hemodialysis instrument
[0065] Fixture Installation
[0066] Observe the surface structure of the hemodialysis instrument, select a flat surface area that does not hinder the operation of the instrument, place the fixture 1 on the area, and ensure that the fixing plate 102 is well attached to the surface of the hemodialysis instrument.
[0067] Just like installing the fixture beside the bed, the knob 104 is rotated to form negative pressure adsorption between the negative pressure block 105 and the surface of the hemodialysis instrument, thereby firmly fixing the fixture 1.
[0068] Sliding plate and fixed head installation
[0069] Considering the position of the pipeline interface on the hemodialysis instrument and the direction of the pipeline, the sliding plate 2 is slid on the sliding groove 101 of the fixer 1 to determine a suitable position.
[0070] According to the method for installing the fixing head in Embodiment 1, the fixing head 3 is installed in the mounting hole 202 of the mounting plate 201 .
[0071] Pipeline fixing
[0072] Since the layout of the pipelines next to the hemodialysis instrument may be more complicated, it is necessary to reasonably place different hemodialysis pipelines in the fixing grooves 303 of the groove plate 302 of the fixing head 3 according to the actual situation. For thicker pipelines, horizontally distributed and wider fixing grooves can be selected; for thinner pipelines, vertically distributed fixing grooves can be selected. Ensure that the clamping force of the elastic plate 304 on the pipeline is moderate, which ensures that the pipeline is firmly fixed without affecting blood circulation.
[0073] In actual use, medical staff can also adjust the position of the sliding plate, the number and position of the fixing heads at any time according to the patient's comfort and actual needs during treatment. At the same time, after each use, just reversely rotate the knob 104 to separate the negative pressure block 105 from the plane, and then easily remove the fixing device, which is convenient for cleaning and storage.
[0074] Through the above specific implementation methods, the hemodialysis pipeline anti-drop device can effectively fix the hemodialysis pipeline and provide reliable protection for hemodialysis treatment.
[0075] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
