Description

Technical Field

[0001] This utility model relates to the field of pipeline positioning devices, and in particular to a pipeline positioning device for hemodialysis in nephrology. Background Technology

[0002] The tubing positioning device for hemodialysis in nephrology is a device specifically designed for the precise fixation and orderly management of various tubing used in the hemodialysis process. It is usually made of medical-grade materials to ensure biocompatibility and safety, and can effectively prevent tubing slippage, twisting or kinking, thereby ensuring the smooth progress of hemodialysis treatment.

[0003] The inventors of this application have discovered the following problems during practical use:

[0004] Currently, there are many problems with tubing positioning devices used in hemodialysis for nephrology. These problems not only affect the smooth progress of the dialysis process but also potentially threaten patient safety. For example, the devices have significant shortcomings in tubing diameter matching. Hemodialysis tubing is designed in various diameters to accommodate different dialysis equipment and patient needs, but existing positioning devices are often limited to fixing tubing of a specific diameter, lacking flexibility. This directly leads to the possibility of tubing loosening or displacement during fixation. In addition, material compatibility issues are particularly prominent. Given the diverse materials used in hemodialysis tubing, such as polyvinyl chloride and polypropylene, each with unique physical and chemical properties, existing positioning devices struggle to achieve good compatibility with tubing of all these materials, thus affecting the fixation effect. More importantly, the limited fixation methods further exacerbate these problems. Most positioning devices on the market rely on bandages and other single fixation methods. This lack of diversity makes it difficult to meet the needs of different patient body shapes, diverse dialysis environments, and complex tubing layouts. Not only is the fixation effect poor, but it may also reduce patient comfort.

[0005] Therefore, it is necessary to provide a tubing positioning device for hemodialysis in nephrology to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the device has insufficient matching of pipe diameter, poor material compatibility and single fixing method. In view of the above-mentioned defects of the prior art, a pipe positioning device for hemodialysis in nephrology is provided.

[0007] To achieve the above objectives, the technical solution of this utility model is: a tubing positioning device for hemodialysis in nephrology, comprising a main body, the main body including a mounting base, the bottom of the mounting base being provided with a Velcro hook surface, a first tubing clamp being provided on one side of the top of the mounting base, an adjustment groove being provided on the other side of the top of the mounting base, a lead screw being provided in the adjustment groove, and one end of the lead screw passing through the mounting base and being provided with a knob;

[0008] A sliding seat is engaged with the lead screw, and a second pipe clamp is provided on the top of the sliding seat.

[0009] By adopting the above technical solution, the Velcro hooks at the bottom of the mounting base can be easily fixed to the patient or dialysis equipment.

[0010] Furthermore, the knob can cause the lead screw to rotate, and after the lead screw rotates, the position of the second pipe clamp can be adjusted through the sliding seat.

[0011] By adopting the above technical solution, the screw is driven to rotate by a knob, which in turn drives the sliding seat and the second pipe clamp to move along the adjustment groove. This design allows the position of the second pipe clamp to be flexibly adjusted according to actual needs.

[0012] Furthermore, the inner walls of both the first and second pipe clamps are bonded with rubber sheets, and the rubber sheets are provided with anti-slip textures.

[0013] By adopting the above technical solution, the inner walls of both the first and second pipe clamps are bonded with rubber sheets with anti-slip textures. This design not only increases the friction between the pipe and the pipe clamp to prevent the pipe from slipping, but also protects the pipe from mechanical damage.

[0014] Furthermore, a first fixing mechanism is provided below the main body, the first fixing mechanism including a skin-friendly patch that can adhere to the skin.

[0015] By adopting the above technical solution, the first fixing mechanism set at the bottom of the main body can fit closely to the patient's skin through the skin-friendly patch, providing additional fixing force.

[0016] Furthermore, the top of the skin-friendly patch is provided with a first hook and loop fastener surface, which is adhered to the hook and loop fastener surface.

[0017] By adopting the above technical solution, the first hook and loop surface of the skin-friendly patch is bonded to the hook and loop surface of the bottom of the main body. This hook and loop connection method is not only simple and easy to use, but also ensures a firm connection between the first fixing mechanism and the main body.

[0018] Furthermore, a second fixing mechanism is provided on one side of the first fixing mechanism. The second fixing mechanism includes a fixing piece, and a second hook and loop fastener is provided on the top of the fixing piece. The second hook and loop fastener can also be adhered to the hook and loop fastener.

[0019] By adopting the above technical solution, the second fixing mechanism set on one side of the first fixing mechanism provides another fixing method through the fixing piece and the second Velcro surface on the top.

[0020] Furthermore, the bottom of the fixing piece is provided with a clip, which can clamp the clothing.

[0021] By adopting the above technical solution, the clip design at the bottom of the fixation plate allows the second fixation mechanism to not only be attached to the patient or dialysis equipment with Velcro, but also to be clipped to the patient's clothing.

[0022] Compared with related technologies, the tubing positioning device for hemodialysis in nephrology provided by this utility model has the following beneficial effects:

[0023] This invention provides a tubing positioning device for hemodialysis in nephrology. The main body includes a knob-driven screw that rotates flexibly within an adjustment groove, precisely controlling the position of the sliding seat and the second tubing clamp. When the second clamp engages with the first clamp, they firmly hold the hemodialysis tubing, achieving precise fixation and adjustment of the tubing position. This feature allows medical staff to easily adjust the tubing position according to the patient's body size, the layout of the dialysis equipment, and the specific route of the tubing, ensuring a smooth dialysis process. Both the first and second clamps have specially bonded rubber sheets with anti-slip textures to their inner walls. This design not only increases the friction between the tubing and the clamps, effectively preventing the tubing from sliding or falling off during dialysis, but the soft material and anti-slip texture of the rubber sheets also greatly reduce pressure on the tubing, lowering the risk of tubing damage. Simultaneously, this thoughtful design improves patient comfort, reducing skin pressure and discomfort caused by prolonged fixation, making the dialysis experience more comfortable and reassuring.

[0024] This utility model provides a tubing positioning device for hemodialysis in nephrology. It comprises a first fixing mechanism and a second fixing mechanism. The core of the first fixing mechanism lies in its skin-friendly patch design. This patch, made of soft and breathable material, fits snugly and comfortably against the patient's skin, enhancing adhesion between the device and the skin, effectively preventing movement or detachment during dialysis, and ensuring patient comfort during prolonged wear. Furthermore, the first Velcro loop on the skin-friendly patch cleverly cooperates with the Velcro hook on the bottom of the main body, enabling quick and convenient attachment and fixing of the device, greatly simplifying the operation process for medical staff. The second fixing mechanism provides more diverse fixing methods through fixing plates and clips. The second Velcro loop on the fixing plate adheres tightly to the Velcro hook on the main body, further enhancing the stability of the device. Particularly noteworthy is the highly flexible design of the clip, which can easily clip onto the patient's clothing, providing a convenient fixing solution for patients who cannot directly attach Velcro due to skin conditions or other reasons.

[0030] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0031] Example 1:

[0032] like Figure 1As shown, the present invention provides a tubing positioning device for hemodialysis in nephrology, comprising a main body 1, the main body 1 including a mounting base 101, the bottom of the mounting base 101 being provided with a Velcro hook surface 102, the top side of the mounting base 101 being provided with a first tubing clamp 103, the other side of the top of the mounting base 101 being provided with an adjustment groove 104, a screw rod 105 being provided in the adjustment groove 104, and one end of the screw rod 105 passing through the mounting base 101 and being provided with a knob 106;

[0033] A sliding seat 107 is engaged with the lead screw 105, and a second tube clamp 108 is provided on the top of the sliding seat 107. The main body 1 of this nephrology hemodialysis tubing positioning device is ingeniously designed. The device is conveniently fixed by the Velcro hook 102 at the bottom of the mounting seat 101. At the same time, the first tube clamp 103 and the second tube clamp 108 provided on the top of the mounting seat 101, together with the adjustment mechanism of the lead screw 105 and the sliding seat 107, provide a stable and adjustable support platform for the hemodialysis tubing, ensuring the stability and safety of the tubing during the dialysis process.

[0034] See Figure 1 , Figure 2 The knob 106 can cause the lead screw 105 to rotate. After the lead screw 105 rotates, the position of the second tube clamp 108 can be adjusted through the sliding seat 107. The introduction of the knob 106 makes the lead screw 105 easy to rotate, thereby driving the sliding seat 107 and the second tube clamp 108 to move precisely within the adjustment groove 104. This design not only improves the flexibility of tube fixation, but also allows for personalized adjustments based on the patient's actual needs and the length of the dialysis tubing, ensuring the best effect of tube fixation.

[0035] See Figure 3 , Figure 4 Both the inner walls of the first tube clamp 103 and the second tube clamp 108 are bonded with rubber sheets, and the rubber sheets are provided with anti-slip textures. The rubber sheets bonded to the inner walls of the first tube clamp 103 and the second tube clamp 108 and the anti-slip textures on them effectively enhance the friction between the tube and the tube clamp, preventing the tube from sliding and falling off. At the same time, the soft material of the rubber sheets also reduces the risk of the tube being compressed, protects the integrity of the tube, and improves the smoothness and safety of the dialysis process.

[0036] Example 2:

[0037] See Figure 3 , Figure 4The first fixing mechanism 2 is provided below the main body 1. The first fixing mechanism 2 includes a skin-friendly patch 201, which can fit in close contact with the skin. The first fixing mechanism 2 provided below the main body 1 achieves close contact with the skin through the skin-friendly patch 201, providing additional fixation support for the device. This design not only improves the stability of the device, but also ensures the comfort of the patient during dialysis and reduces discomfort caused by device movement or shaking.

[0038] See Figure 3 , Figure 4 The top of the skin-friendly patch 201 is provided with a first hook and loop fastener 202, which is attached to the hook and loop fastener 102. The first hook and loop fastener 202 on the top of the skin-friendly patch 201 is attached to the hook and loop fastener 102 on the bottom of the main body 1, forming a simple and effective fixing method. This hook and loop fastener connection is not only easy to operate, but can also be flexibly adjusted according to the patient's body shape and dialysis needs, ensuring a tight fit and stable fixation between the device and the skin.

[0039] See Figure 3 , Figure 4 A second fixing mechanism 3 is provided on one side of the first fixing mechanism 2. The second fixing mechanism 3 includes a fixing piece 301. A second hook and loop fastener 302 is provided on the top of the fixing piece 301. The second hook and loop fastener 302 can also be attached to the hook and loop fastener 102. The second fixing mechanism 3 provided on one side of the first fixing mechanism 2 provides another reliable fixing method through the fixing piece 301 and the second hook and loop fastener 302 on the top. This design not only increases the fixing points of the device, but also realizes quick connection and disassembly with the main body 1 through the hook and loop fastener connection, which is convenient for medical staff to operate and maintain.

[0040] See Figure 1 , Figure 4 The bottom of the fixing plate 301 is provided with a clip 303, which can clamp the clothing. The clip 303 at the bottom of the fixing plate 301 provides another fixing method for the device besides Velcro connection. The clip 303 can clamp the patient's clothing, providing a convenient fixing solution for patients who cannot directly use Velcro connection. This diversified fixing method not only improves the applicability of the device, but also ensures a stable and reliable fixing effect in different scenarios.

[0041] In practice, firstly, based on the patient's specific condition, a suitable fixation method is selected. If it can be directly pasted onto the skin, the first fixation mechanism 2 is used: the skin-friendly patch 201 is attached to the patient's skin, ensuring it is flat and wrinkle-free, and then the first Velcro loop side 202 is bonded to the Velcro hook side 102 at the bottom of the main body 1 to fix the device; if it cannot be directly pasted onto the skin, or if additional fixation points are required, the second fixation mechanism 3 is used: the fixation piece 301 is bonded to the Velcro hook side 102 of the main body 1 through the second Velcro loop side 302, and at the same time, the clip 303 is used to hold it to the patient's clothing to increase the fixation stability;

[0042] Place one end of the hemodialysis tubing into the first clamp 103, ensuring the tubing is tightly wrapped by the rubber sheet. The anti-slip texture serves to fix the tubing in place. Depending on the specific direction and length of the tubing, rotate the knob 106 to drive the lead screw 105 to rotate within the adjustment groove 104. The rotation of the lead screw 105 will cause the sliding seat 107 and the second clamp 108 to move along the lead screw axis. After adjusting to the appropriate position, place the other end of the tubing into the second clamp 108, again ensuring the tubing is tightly fixed.

[0043] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0044] 1. By rotating the screw within the adjustment groove using a knob, this device precisely controls the position of the sliding seat and the second tubing clamp, thereby achieving accurate fixation and adjustment of the hemodialysis tubing position. This design greatly facilitates personalized adjustments by medical staff based on the patient's body shape, dialysis equipment layout, and tubing routing, ensuring a smooth and efficient dialysis process.

[0045] 2. The rubber sheet with anti-slip texture that adheres specially to the inner walls of the first and second tubing clamps not only increases the friction between the tubing and the clamps, effectively preventing the tubing from slipping or falling off, but also reduces pressure on the tubing through its soft material and anti-slip texture, lowering the risk of breakage. This design ensures the safety of the dialysis process and improves patient comfort.

[0046] 3. The first fixation mechanism uses a soft and breathable skin-friendly patch that can fit snugly and comfortably against the patient's skin, enhancing adhesion and preventing the device from shifting or falling off. Simultaneously, the hook-and-loop fastener on the skin-friendly patch mates with the hook-and-loop fastener on the bottom of the main body, enabling quick and convenient attachment and simplifying the operation process.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
