Description

Technical Field

[0001] This utility model belongs to the field of fixing technology, specifically relating to a dialysis tubing fixing device. Background Technology

[0002] Hemodialysis is a treatment method that uses a hemodialysis machine. During dialysis, blood containing metabolic waste and harmful substances is first infused into the dialyzer through the arterial end of the extracorporeal circulation tubing. The dialyzer's semi-permeable membrane removes these wastes and harmful substances, purifying the blood. The purified blood is then reinfused into the body through the venous end of the extracorporeal circulation tubing. The extracorporeal circulation tubing for hemodialysis is a crucial component connecting the patient and the dialysis machine, and consists of arterial tubing, venous tubing, and optional components; hereinafter, these are collectively referred to as the tubing.

[0003] However, during dialysis, the long tubing can be easily moved or pulled by the patient's hand movements, affecting the stability of the puncture needle. Additionally, the tubing may dangle from the bed edge, and medical staff may accidentally touch it while moving around or performing procedures, disrupting the dialysis process. Therefore, to ensure dialysis can proceed smoothly, medical tape or tubing clamps are typically used to secure the tubing to the patient's sheets, bed rails, skin, or clothing. This prevents the tubing from moving and affecting the puncture site, and also prevents it from dangling from the bed edge and accidentally coming into contact with passing personnel.

[0004] However, securing pipes with tape requires at least two points, or even multiple points, to ensure a stable connection. This necessitates repeatedly applying tape, attaching it to the pipe, and then sticking the tape to the connected components, making the process quite cumbersome. To reduce the workload, rigid clamps are sometimes used to secure the pipes. However, rigid clamps exert a strong clamping force, which may obstruct the flow of fluid through the pipes. Utility Model Content

[0005] This utility model discloses a pipe fixing device, which aims to solve the technical problem that the existing technology of fixing pipes with tape or the like is too cumbersome.

[0006] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] A pipe fixing device includes a base with a first fixing part that mates with a crossbar. The base also has a second fixing part for fixing the pipe. The second fixing part includes a fixing plate slidably connected to the base. The base and the fixing plate each have a first fixing groove and a second fixing groove. The fixing plate slides to bring the first and second fixing grooves to the same horizontal plane, forming a through groove for fixing the pipe. The fixing plate has a fixing mechanism for fixing the pipe, and the fixing mechanism also has a second telescopic device for limiting the pipe's movement. The first telescopic device is located between the fixing plate and the base, and contains a fluid. The first telescopic device communicates with the second telescopic device, and the fluid flows between the first and second telescopic devices through the sliding of the fixing plate. With this technical solution, the pipe is fixed by the protective groove formed by the first fixing groove, the second fixing groove, and the fixing mechanism when the fixing plate and the base are connected by the first and second fixing grooves, resulting in good protection and fixing effect.

[0008] Meanwhile, to further enhance the fixation effect and simplify the fixation method, the sliding fixing plate compresses the first telescopic device within the base. Fluid flows from the first telescopic device into the second telescopic device. With the first and second fixing slots connected to protect the pipeline, the fluid fills the second telescopic device, bringing it into contact with the pipeline and limiting its movement. Compared to repeatedly connecting tape to the pipeline and the adhered object, this device only requires connecting it to the crossbar, placing the pipeline in the first and second fixing slots, and then pressing the fixing plate to achieve pipeline fixation. Therefore, the fixation method is simpler, easier to operate, and can improve the work efficiency and comfort of medical staff.

[0009] The fixing mechanism is an arc-shaped elastic plate with an opening. The tubing enters the protective groove formed by the fixing mechanism and the second fixing groove through the opening. The second telescopic device is located inside the elastic plate. With this technical solution, the size of the opening is smaller than the diameter of the tubing. Because the fixing mechanism is an elastic plate, the tubing is restricted by the protective groove after entering through the opening, preventing radial movement and increasing the stability of the tubing during dialysis. This fixing method using the elastic plate and opening is also relatively simple. Furthermore, the elastic plate and opening can be used with tubing of any diameter to restrict tubing of any diameter, making the device more practical.

[0010] The first telescopic device is an elastic pad, and the second telescopic device is an elastic bladder in the shape of a skeleton. The elastic pad and the elastic bladder are connected through a first conveying channel disposed in the fixed plate. The first conveying channel is sealed to the elastic pad and the elastic bladder.

[0011] In this technical solution, the fluid only flows within the first and second telescopic devices during the compression and separation of the fixed plate and the elastic pad, and will not flow elsewhere, thus making the device more stable during use. Furthermore, the skeleton-shaped elastic bladder reduces the amount of fluid required within it, thereby reducing fluid usage and lowering costs.

[0012] The base is provided with a second material conveying channel, which is sealed and connected to the elastic pad. The second material conveying channel passes through the first fixing part and is connected to the outside. The second material conveying channel is also provided with a first sealing device.

[0013] After adopting this technical solution, since the second conveying channel is connected to the outside, when the fluid is air, air can be directly replenished from the outside, which can further reduce costs; when the fluid is other liquid fluids such as water, the water in the elastic pad can be replenished through the second conveying channel, so that the fluid variation of this device is smaller and more stable during use.

[0014] The first fixing part includes a slot disposed on the base, the slot cooperating with the crossbar, an elastic element disposed in the slot, and the second conveying channel passing through the elastic element and communicating with the outside.

[0015] With this technical solution, the slot and the horizontal bar cooperate to directly fix the device to the horizontal bar through the fit of their shapes, making the fixing method simple. The elastic element creates a compressive force between the device and the horizontal bar, further increasing the stability of the connection between the device and the horizontal bar, thereby increasing the stability of the device during use.

[0016] The base has a groove for accommodating a fixing plate, the side wall of the groove has a sliding groove, the fixing plate has a slider that cooperates with the sliding groove, and the first telescopic device is placed in the groove.

[0017] By adopting this technical solution, the position of the fixing plate can be limited by the setting of the sliding groove and the slider, so that the fixing plate will not slide out of the groove, which increases the stability of the device during use. At the same time, the setting of the sliding groove and the slider can simplify the structure of the device and make the device easier to process.

[0018] The slider and the bottom of the groove are provided with locking devices.

[0019] With this technical solution, the locking device locks the position of the fixing block when the fixing plate contacts the bottom of the groove, so that all the fluid in the first telescopic device is used to limit the pipeline, which increases the stability of the device during use.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] (1) Using a first telescopic device, a second telescopic device, a fixing plate, a base, etc., the first fixing part is fixed to the crossbar, and then the pipeline is placed in the second fixing device. Finally, the base is squeezed to fix the pipeline. The fixing method is simpler than the tape fixing method, which can improve the work efficiency and user experience of medical staff.

[0022] (2) The use of elastic plates and openings restricts the directional and lateral movement of the tubing, increasing the stability of the tubing during dialysis. This fixing method using elastic plates and openings is also relatively simple. At the same time, the setting of elastic plates and openings can be used with tubing of any diameter, making the device more practical.

[0023] (3) Using elastic bladders with a skeleton shape can reduce the amount of fluid required in the elastic bladder, thereby reducing the amount of fluid used and reducing costs. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] In the description of the embodiments of this application, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] The following is combined with Figures 1-3 This utility model will be described in detail.

[0033] A pipe fixing device, such as Figures 1-3 As shown, the system includes a base 1, on which a first fixing part is provided to cooperate with a crossbar. The base 1 also has a second fixing part for fixing pipelines. The second fixing part includes a fixing plate 2 slidably connected to the base 1. The base 1 and the fixing plate 2 are respectively provided with a first fixing groove 104 and a second fixing groove. The fixing plate 2 slides to make the first fixing groove 104 and the second fixing groove lie on the same horizontal plane to form a through groove for fixing pipelines. The fixing plate 2 is provided with a fixing mechanism for fixing pipelines. The fixing mechanism is also provided with a second telescopic device for limiting the movement of pipelines. A first telescopic device is provided between the fixing plate 2 and the base 1. The first telescopic device contains fluid. The first telescopic device is connected to the second telescopic device. The fluid flows between the first telescopic device and the second telescopic device by sliding the fixing plate 2.

[0034] In this embodiment, both the base 1 and the fixing plate 2 are made of stainless steel. Stainless steel has a clean and aesthetically pleasing appearance, is not prone to rust, and will not damage the pipeline upon contact. Furthermore, stainless steel can be disinfected and reused, thereby reducing costs. In other embodiments, the base 1 and the fixing plate 2 can also be made of PVC. PVC has a smooth surface, will not damage the pipeline upon contact, and is inexpensive, allowing for the creation of disposable devices. After use, the device can be disposed of after treatment, reducing the possibility of cross-infection.

[0035] In this embodiment, as Figure 1 As shown, when the fixing plate 2 presses against the first telescopic device, making the upper surface of the fixing plate 2 parallel to the upper surface of the base 1, the first fixing groove 104 and the second fixing groove are connected.

[0036] In this embodiment, the dimensions of the first fixing groove 104 and the second fixing groove are matched with the radius of the pipeline.

[0037] In this embodiment, the fluid can be any fluid-flowing substance such as gas or liquid; in this embodiment, the fluid is air.

[0038] The first fixing part is connected and fixed to the horizontal rail, such as the bed rail or the chair rail of the seat. When the pipeline is connected to the second fixing groove and the first fixing groove 104 on the fixing plate 2 and the base 1, it is fixed by the protective groove formed by the first fixing groove 104, the second fixing groove and the fixing mechanism, so the protection and fixing effect is good.

[0039] Meanwhile, to further enhance the fixation effect and simplify the fixation method, the sliding fixing plate 2 compresses the first telescopic device within the base 1. Fluid flows from the first telescopic device into the second telescopic device. With the first fixing groove 104 and the second fixing groove connected to protect the pipeline, the fluid fills the second telescopic device, bringing it into contact with the pipeline and limiting its movement. Compared to repeatedly connecting tape to the pipeline and the adhered object, this device only requires connecting it to the crossbar, placing the pipeline in the first fixing groove 104 and the second fixing groove, and then pressing the fixing plate 2 to fix the pipeline. Therefore, the fixation method is simpler and easier to operate, improving the work efficiency and comfort of medical staff.

[0040] In this embodiment, the fixing mechanism is an arc-shaped elastic plate 205 with an opening. The pipeline enters the protective groove formed by the fixing mechanism and the second fixing groove through the opening. The second telescopic device is located on the inner side of the elastic plate 205.

[0041] In this embodiment, the elastic plate 205 is made of silicone. The elastic plate 205 made of silicone has a certain degree of elasticity while having a certain degree of hardness. At the same time, the silicone material makes the cost of this device lower.

[0042] In this embodiment, the elastic plate 205 is bonded to the side wall of the second fixing groove. The bonding makes the two connecting surfaces relatively flat, improving the accuracy of the device.

[0043] In this embodiment, the dimensions of the protective groove formed by the elastic plate 205 and the second fixing groove are matched with the dimensions of the pipeline.

[0044] The opening is smaller than the diameter of the tubing. Because the fixing mechanism is an elastic plate 205, the tubing is confined by the protective groove after entering through the opening, preventing radial movement and increasing stability during dialysis. This fixing method using the elastic plate 205 and the opening is also relatively simple. Furthermore, the elastic plate 205 and the opening can be used with tubing of any diameter, restricting tubing of any diameter and enhancing the practicality of the device.

[0045] In this embodiment, the first telescopic device is an elastic pad 3, and the second telescopic device is an elastic bladder 201 in the shape of a skeleton. The elastic pad 3 and the elastic bladder 201 are connected through a first conveying channel 203 disposed in the fixed plate 2. The first conveying channel 203 is sealed to the elastic pad 3 and the elastic bladder 201.

[0046] In this embodiment, both the elastic bladder 201 and the elastic pad 3 are sealed to the first conveying channel 203 by adhesion.

[0047] In this embodiment, three first conveying channels 203 are provided, and all three first conveying channels 203 are sealed and adhered to the elastic bladder 201 and the elastic pad 3.

[0048] In this embodiment, the first conveying channel 203 and the elastic bladder 201 are sealed and connected by the second check valve 202. The check valve and the connection between the check valve and the pipeline described in this embodiment are existing technologies. When the fluid pressure is high enough, the check valve will open automatically, but when the pressure is insufficient, it will close automatically. Such as ball check valve, diaphragm check valve, etc. In this embodiment, a diaphragm check valve is used, which will not be described in detail here.

[0049] In this embodiment, the fluid can only enter the elastic bladder 201 through the second one-way valve 202.

[0050] In this embodiment, the elastic bladder 201 is connected to a material delivery pipe, which is connected to the elastic pad 3. When the fixing plate 2 releases its pressure on the elastic pad 3, the fluid in the elastic bladder 201 will flow into the elastic pad 3, which is convenient for the next fixing.

[0051] The fluid only flows within the first and second telescopic devices during the compression and separation of the fixed plate 2 and the elastic pad 3, and will not flow elsewhere, making the device more stable during use. Furthermore, the skeleton-shaped elastic bladder 201 reduces the amount of fluid required within it, thereby reducing fluid usage and lowering costs.

[0052] In this embodiment, a second material conveying channel 101 is provided inside the base 1. The second material conveying channel 101 is sealed and connected to the elastic pad 3. The second material conveying channel 101 passes through the first fixing part and is connected to the outside. The second material conveying channel 101 is also provided with a first sealing device.

[0053] In this embodiment, six second conveying channels 101 are provided, and the first sealing device is a first one-way valve 102. Each second conveying channel 101 is connected to a first one-way valve 102. Fluid can be replenished into the elastic pad 3 from the first one-way valve 102.

[0054] Because the second conveying channel 101 is connected to the outside, when air is used as the fluid, air can be directly replenished from the outside, which can further reduce costs; when other liquid fluids such as water are used, water in the elastic pad 3 can be replenished through the second conveying channel 101, so that the fluid of this device changes less and is more stable during use.

[0055] In this embodiment, the first fixing part includes a slot 105 disposed on the base 1. The slot 105 cooperates with the crossbar. An elastic element 4 is disposed in the slot 105. The second material conveying channel 101 passes through the elastic element 4 and communicates with the outside.

[0056] In this embodiment, the slot 105 and the base 1 are integrally formed.

[0057] In this embodiment, the elastic element 4 is bonded to the slot 105.

[0058] The slot 105 engages with the horizontal bar, allowing the device to be directly fixed to the horizontal bar through a simple fit. The elastic element 4 creates a compressive force between the device and the horizontal bar, further increasing the stability of the connection between them and thus enhancing the stability of the device during use.

[0059] In this embodiment, the base 1 is provided with a groove for accommodating the fixing plate 2, the side wall of the groove is provided with a sliding groove 103, the fixing plate 2 is provided with a slider 204 that cooperates with the sliding groove 103, and the first telescopic device is placed in the groove.

[0060] In this embodiment, the groove and slide 103 are integrally formed with the base 1.

[0061] In this embodiment, the elastic pad 3 and the two sides of the groove that are close to each other are connected by adhesive. When the elastic pad 3 is damaged, it can be replaced, reducing costs.

[0062] In this embodiment, the slider 204 and the fixing plate 2 are integrally formed by welding.

[0063] In this embodiment, the base 1 is also provided with a stop to limit the slider 204.

[0064] The setting of the slide groove 103 and the slider 204 can limit the position of the fixing plate 2, so that the fixing plate 2 will not slide out of the groove, which increases the stability of the device during use. At the same time, the setting of the slide groove 103 and the slider 204 can simplify the structure of the device and make the device easier to process.

[0065] In this embodiment, the slider 204 and the bottom of the slide groove 103 are provided with locking devices.

[0066] In this embodiment, the locking device is a magnetic suction component located on the bottom contact surface of the slider 204 and the slide groove 103. When the fixing plate 2 presses the elastic pad 3, it can be fixed by the magnetic suction component.

[0067] The locking device locks the position of the fixing block when the fixing plate 2 contacts the bottom of the groove, so that all the fluid in the first telescopic device is used to limit the pipeline, which increases the stability of the device during use.

[0068] The specific method of using this utility model is as follows:

[0069] Reference Figures 1-3 In use, this device is first injected into the elastic pad 3 with a fluid (such as air). The first one-way valve 102 prevents air from overflowing from the elastic element 4. Then, the slot 105 on the base 1 is aligned with the horizontal rail of a bed or chair, and the device is snapped onto the horizontal rail. Due to its elasticity, the elastic element 4 assists the slot 105 in compressing the horizontal rail when it contacts the rail. Then, the pipe passes through the opening and contacts the first fixing slot 104 and the second fixing slot, initially restricting the pipe. Then press the fixing plate 2, allowing it to slide in the base 1 until it is attracted by the magnetic component. This serves two purposes: first, it causes the elastic component 4 to contact the horizontal bar, squeezing the horizontal bar and further fixing the device to the horizontal bar; second, it causes the fixing plate 2 to squeeze the elastic pad 3, allowing the fluid in the elastic pad 3 to enter the elastic bladder 201 from the second one-way valve 202. The elastic bladder 201 and the elastic plate 205 cooperate to wrap the outer wall of the pipeline, limiting the axial and radial positions of the pipeline, thereby limiting the pipeline.

[0070] Then, turn on the hemodialysis machine and perform dialysis. After dialysis, when there is no blood flow in the tubing, squeeze the elastic plate 205 directly to allow the air in the elastic bladder 201 of the elastic plate 205 to re-enter the elastic pad 3. This causes the fixing plate 2 to slide upward under the action of the air flowing back into the elastic pad 3, disconnecting the magnetic connector. Then, remove the tubing from the opening and disconnect the device from the crossbar. The device can be reused after sterilization. If the fluid in the elastic pad 3 is insufficient, it can be replenished through the first one-way valve 102.

[0071] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
