Description

Technical Field

[0001] The present invention relates to the technical field of blood dialysis tube anti - shedding devices, and specifically to a blood dialysis tube anti - shedding device for nephrology nursing. Background Art

[0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves draining the blood in the body to the outside, passing it through a dialyzer composed of countless hollow fibers. Inside and outside these hollow fibers, the blood exchanges substances with an electrolyte solution (dialysate) with a concentration similar to that of the body through the principles of diffusion, ultrafiltration, adsorption, and convection, removing metabolic wastes in the body, maintaining electrolyte and acid - base balance; at the same time, removing excess water in the body, and the whole process of returning the purified blood is called hemodialysis. During hemodialysis, the hemodialysis tube needs to be fixed in a specific position to prevent shedding or displacement, otherwise it may lead to the interruption of treatment and even cause serious consequences.

[0003] In existing hemodialysis tube fixing devices, common methods include simple clip or bandage fixation. Simple clip fixation often has difficulty adapting to hemodialysis tubes of different diameters, and the fixation is not firm. When the patient makes a slight movement or the hospital bed vibrates, the hemodialysis tube is likely to slip. Although bandage fixation has a certain stability, it is inconvenient to operate, and it is rather cumbersome to adjust the position of the hemodialysis tube. The winding strength of the bandage is not easy to control. Being too tight may damage the hemodialysis tube, and being too loose will not be able to play an effective fixing role.

[0004] The main problem with the existing technology is that its fixing effect is insufficient. Especially when the hemodialysis tube is subjected to external pulling or vibration, there is a risk of slippage, and it cannot fully guarantee the continuity and safety of treatment. This problem may lead to the interruption of the patient's treatment process and even cause serious medical accidents. Summary of the Invention

[0005] In view of the deficiencies of the existing technology, the present invention provides a blood dialysis tube anti - shedding device for nephrology nursing, which solves the problem that when the hemodialysis tube is subjected to external pulling or vibration, there is a risk of slippage, and it cannot fully guarantee the continuity and safety of treatment.

An extension mechanism is arranged at the bottom of the support plate, and a desktop folding - type extension plate is arranged at the bottom of the extension mechanism.

[0007] The placement and fixation mechanism includes a first placement plate and a second placement plate. The first placement plate is fixedly connected to the top of the support plate. The first placement plate is rotatably connected to the second placement plate. A first placement groove is formed on the top of the first placement plate. A second placement groove is formed on the opposite side of the second placement plate relative to the first placement plate. The first placement groove and the second placement groove are curved. Three anti-slip bumps are fixedly connected to the inner walls of the first placement groove and the second placement groove. A plurality of groups of grooves are formed on the first placement plate, and each group has two grooves. One end of each of the two first springs is fixedly connected to a movable plate, and one end of the two movable plates close to each other is fixedly connected to a fixed block.

[0008] Preferably, a first magnet is fixedly connected to one side of the top of the first placement plate, and a second magnet is fixedly connected to one side of the bottom of the first magnet. The first magnet cooperates with the second magnet.

[0009] Preferably, rubber blocks are arranged on the opposite sides of the two fixed blocks.

[0010] Preferably, the limiting mechanism includes a limiting block and a support block. The support block is fixedly connected to the top of the support plate. Two sliding rods are connected to the bottom of the limiting block, and the sliding rods are slidably connected to the support plate. A fixing component is arranged on the outer side of the sliding rods, and the fixing component is used to fix the sliding rods.

[0011] Preferably, the fixing component includes an installation shell. The installation shell is fixedly connected to the bottom of the support plate. A moving plate is slidably connected to the inner wall of the installation shell. A plug rod is fixedly connected to one end of the moving plate close to the slot. A pull rod is fixedly connected to the other end of the moving plate away from the slot. A second spring is sleeved on the outer side of the pull rod, and the second spring is fixedly connected between the moving plate and the installation shell. A slot is formed on the outer side of one of the sliding rods, and the installation shell is inserted and matched with the slot.

[0012] Preferably, a second sponge pad is arranged on the bottom of the limiting block, and a first sponge pad is arranged on the top of the support block.

[0013] Preferably, the extension mechanism includes two fixed frames. The two fixed frames are respectively fixedly connected to the two sides of the top of the desktop folding extension plate. Sliders are fixedly connected to the two sides of the bottom of the support plate, and the sliders are slidably connected to the fixed frames. A locking component is arranged at the bottom of the support plate, and the locking component is used to lock the position of the support plate.

[0014] Preferably, the locking component includes a fixed screw rod. The fixed screw rod is fixedly connected to the bottom of the support plate. A sliding hole is formed on the top of the desktop folding extension plate.

[0015] The present invention provides a hemodialysis tube anti - detachment device for nephrology nursing, with the following beneficial effects:

[0016] 1. Through the cooperation of the first placement plate and the second placement plate, the hemodialysis tube is fixed in the placement groove. The rubber block is soft and elastic, which can prevent the surface of the hemodialysis tube from being damaged while fixing it, protecting the integrity of the hemodialysis tube. The elastic force of the first spring makes the rubber block automatically press tightly on the hemodialysis tube, making its fixation more stable and meeting the usage requirements of hemodialysis tubes with different diameters. The mutual adsorption of the first magnet and the second magnet further enhances the stability of the second placement plate, preventing loosening or displacement. The anti - slip bumps effectively prevent the hemodialysis tube from slipping off during vibration or pulling by increasing the inner wall friction, ensuring the stability and safety of the hemodialysis tube during the treatment process, significantly reducing the risk of hemodialysis tube detachment, and improving the safety and efficiency of clinical use.

[0017] 2. Through the flexible fixation of the first sponge pad and the second sponge pad, effective protection and fixation of the hemodialysis tube are achieved, preventing extrusion damage or indentation on the surface of the hemodialysis tube, and at the same time extending the service life of the hemodialysis tube. Secondly, by enhancing the friction force, the hemodialysis tube is effectively prevented from slipping due to external force or patient movement, ensuring its stability in the fixed position. The tight fit of the insertion rod and the insertion slot, as well as the restoring force of the second spring, provide a reliable limiting function, making the sliding rod stable in position and convenient to adjust. The overall design simplifies the operation process. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 9, an embodiment of the present invention provides a hemodialysis tube anti-detachment device for nephrology nursing, including a support plate 1. The support plate 1 serves as the main body and foundation of the entire device, bearing various functional components, providing stable structural support, and ensuring the coordinated operation of the overall device functions. Multiple placement and fixation mechanisms 2 are provided on the top of the support plate 1, which are used to stabilize the position of the hemodialysis tube, providing a multi-point fixation design to adapt to different numbers of hemodialysis tubes, ensuring the stability and safety of the hemodialysis tube during the treatment process. Multiple limiting mechanisms 3 are provided on the top of the support plate 1. The limiting mechanisms 3 cooperate with the placement and fixation mechanisms 2 to further limit and protect the hemodialysis tube, preventing displacement due to external forces and improving the reliability of fixation. The number of placement and fixation mechanisms 2 corresponds to that of the limiting mechanisms 3, ensuring that each hemodialysis tube has a dedicated fixation and limiting component, precisely matching the usage requirements, avoiding omission or interference with other hemodialysis tubes, and enhancing the practicality and accuracy of the device. The limiting mechanisms 3 are arranged at the outlet of the placement and fixation mechanisms 2. The limiting mechanisms 3 are arranged at key positions, effectively restricting the movement range of the hemodialysis tube, preventing slippage without affecting the normal use of the hemodialysis tube. An extension mechanism 5 is provided at the bottom of the support plate 1. The extension mechanism 5 cooperates with the desktop folding extension plate 4 to achieve flexible movement and position locking of the support plate 1, enhancing the fixation effect of the hemodialysis tube, meeting the personalized needs of patients, and ensuring treatment safety and comfort. A desktop folding extension plate 4 is provided at the bottom of the extension mechanism 5. The desktop folding extension plate 4 is an existing product, which is firmly installed at a suitable position such as the bedside or the bed frame through a non-drilling fixture. When unfolded, the extension plate is flipped to a horizontal state using a hinge connection, flush with the bed surface to form an integral whole. The weight is jointly borne by the fixture and the hidden support rod to ensure the stability and safety of the extension plate. Through the desktop folding extension plate 4, it can be folded up when not in use. Through the folding structure, it closely fits the surrounding environment and reduces the occupied space. For example, in a hospital ward with limited space, when the hemodialysis equipment does not require the use of the extension plate, the folded extension plate can be closely attached to the edge of the bed surface or stored in the corner beside the bed.

[0031] The placement and fixation mechanism 2 includes a first placement plate 201 and a second placement plate 202. The first placement plate 201 is fixedly connected to the top of the support plate 1. The first placement plate 201 is rotatably connected to the second placement plate 202. A first placement groove 205 is formed in the top of the first placement plate 201. A second placement groove 206 is formed in the opposite side of the second placement plate 202 relative to the first placement plate 201. The first placement groove 205 and the second placement groove 206 are curved. Three anti-slip bumps 207 are fixedly connected to the inner walls of both the first placement groove 205 and the second placement groove 206. A plurality of groups of grooves are formed in the first placement plate 201, and a first spring 208 is fixedly connected to each group of grooves. The number of grooves in each group is two. The adjacent ends of the two first springs 208 are fixedly connected to a movable plate 209. The adjacent ends of the two movable plates 209 are fixedly connected to a fixed block 2010. Rubber blocks 2011 are arranged on the opposite sides of the two fixed blocks 2010. Through the rotational connection between the first placement plate 201 and the second placement plate 202, a curved structure of the first placement groove 205 and the second placement groove 206 is formed, realizing the stable fixation of the hemodialysis tube and facilitating its use. Through the anti-slip bumps 207 on the inner walls of the first placement groove 205 and the second placement groove 206, the friction between the inner wall and the hemodialysis tube is increased, realizing the effect of effectively preventing the hemodialysis tube from slipping under vibration or external force. Through the plurality of groups of grooves on the first placement plate 201 and the elastic reset function of the first spring 208, the movable plate 209 and the fixed block 2010 are driven to clamp the hemodialysis tube, realizing the automatic clamping and fixation of the hemodialysis tube, improving the operation convenience and the stability of the fixation effect. Through the two movable plates 209 and the fixed block 2010 pressing the hemodialysis tube against each other under the action of the first spring 208, and the fixed block 2010 is attached with a soft rubber block 2011, while stabilizing the hemodialysis tube, the surface of the hemodialysis tube is protected from being squeezed or damaged, and the service life of the hemodialysis tube is prolonged.

[0032] Please refer to Figures 6 - 7 , a first magnet 203 is fixedly connected to one side of the top of the first placement plate 201. A second magnet 204 is fixedly connected to one side of the bottom of the first magnet 203. The first magnet 203 cooperates with the second magnet 204. By utilizing the mutual adsorption effect between the first magnet 203 and the second magnet 204, the stable locking of the second placement plate 202 during use is realized, preventing it from loosening or displacing, enhancing the stability of the placement plate while fixing the hemodialysis tube. By replacing the complex mechanical locking structure with magnet adsorption, the functions of quick locking and unlocking are realized, improving the use convenience of the device.

[0033] Please refer to Figure 1 , Figure 9 and Figure 10The limiting mechanism 3 includes a limiting block 301 and a supporting block 303. A sponge pad 2 305 is provided at the bottom of the limiting block 301, and a sponge pad 1 304 is provided at the top of the supporting block 303. The supporting block 303 is fixedly connected to the top of the supporting plate 1. Two sliding rods 302 are connected to the bottom of the limiting block 301. The sliding rods 302 are slidably connected to the supporting plate 1. A fixing component is provided on the outer side of the sliding rod 302. The fixing component is used to fix the sliding rod 302. The fixing component includes a mounting shell 307. The mounting shell 307 is fixedly connected to the bottom of the supporting plate 1. A moving plate 308 is slidably connected to the inner wall of the mounting shell 307. The moving plate 308 is fixedly connected to one end of the slot 306 A plug rod 309 is connected, and a pull rod 3010 is fixedly connected to one end of the movable plate 308 away from the slot 306. The outer sleeve of the pull rod 3010 is provided with a spring 2 3011, and the spring 2 3011 is fixedly connected between the movable plate 308 and the mounting shell 307. A slot 306 is provided on the outer side of one of the slide bars 302, and the mounting shell 307 is plugged and matched with the slot 306. Through the combination of the limit block 301 and the support block 303, a sponge pad 2 305 is arranged at the bottom, and a sponge pad 1 304 is arranged at the top. The flexible material of the sponge pad is used to form a buffer protection for the hemodialysis tube, so that the surface of the hemodialysis tube is prevented from being damaged or leaving an indentation while fixing the hemodialysis tube, thereby extending the service life of the hemodialysis tube. Through the sliding connection between the slide bar 302 at the bottom of the limit block 301 and the support plate 1, a fixed component is arranged on the outer side of the slide bar 302, and the slide bar 302 can be flexibly moved along the support plate 1 and locked in position through the fixed component, so that the position of the limit block 301 can be adjusted to accommodate hemodialysis tubes of different sizes or positions. Through the plug-in cooperation of the mounting shell 307, the insertion rod 309 and the slot 306 in the fixed component, combined with the sliding connection of the movable plate 308 and the reset function of the second spring 3011, pulling the pull rod 3010 can make the insertion rod 309 disengage from the slot 306, thereby realizing the unlocking and adjustment of the slide bar 302. After releasing the pull rod 3010, the insertion rod 309 automatically resets and inserts into the slot 306 to lock the slide bar 302. Through the sliding of the movable plate 308 and the mounting shell 307, and the elastic reset function of the second spring 3011, the spring reset force is utilized to ensure that the limit assembly always remains in a locked state, thereby realizing the stability and safety of the limit mechanism 3 and preventing the hemodialysis tube from sliding under the action of external force.

[0034] See also Figures 1 - 4, the extension mechanism 5 includes two fixed frames 501 which are respectively fixedly connected to both sides of the top of the tabletop folding extension plate 4. Both sides of the bottom of the support plate 1 are fixedly connected with sliders 502, and the sliders 502 are slidably connected with the fixed frames 501. A locking component is arranged at the bottom of the support plate 1, and the locking component is used to lock the position of the support plate 1. The locking component includes a fixed screw 503 which is fixedly connected to the bottom of the support plate 1. A sliding hole 505 is formed in the top of the tabletop folding extension plate 4. The fixed screw 503 is engaged with the sliding hole 505, and a fixed nut 504 is threadedly connected to the bottom of the fixed screw 503. Through the cooperation of the two fixed frames 501 of the extension mechanism 5 and the sliders 502, the sliders 502 slide along a specific track in the fixed frames 501, so that the support plate 1 can move flexibly to meet the needs of patients in different positions. Through the cooperation of the fixed screw 503 and the sliding hole 505, the fixed nut 504 is screwed onto the fixed screw 503 to lock the position of the support plate 1. This locking mechanism ensures that during hemodialysis treatment, the support plate 1 can remain stable and will not be displaced due to external forces or patient movement. Through the mutual cooperation of the above structures, the placement and fixing mechanism 2 and the limiting mechanism 3 can move to a suitable position along with the support plate 1, so as to provide stable and precise fixation for the hemodialysis tube. At the same time, since the position of the support plate 1 can be adjusted according to the specific situation of the patient, the fitting degree between the hemodialysis tube and the patient's body is higher, avoiding the compression or discomfort caused to the patient due to the improper position of the hemodialysis tube, and improving the comfort of the patient.

[0035] Working principle: First, use the tabletop folding extension plate 4 to fix the device at a suitable position such as the edge of the bed or the bed frame. Then, according to the patient's situation, move the position of the support plate 1 and the patient. By pushing the support plate 1, the slider 502 slides along a specific track in the fixed frame 501, thereby driving the placement and fixing mechanism 2 and the limiting mechanism 3 to move together. When the support plate 1 is moved to a suitable position so that the placement and fixing mechanism 2 and the limiting mechanism 3 have a suitable position with the patient, the fixation of the hemodialysis tube is more perfect. By rotating the fixed nut 504 onto the fixed screw 503, the position of the support plate 1 is locked, improving the comfort and meeting the personalized needs of the patient, and ensuring the treatment effect.

[0036] At this time, by rotating the placing plate two 202, the hemodialysis tube is placed in the placing groove one 205 of the placing plate one 201. When the hemodialysis tube is placed in the placing groove one 205, the hemodialysis tube will first come into contact with the rubber block 2011. At this time, the fixed block 2010 is driven, causing the moving plate 308 to slide in the groove and compress the first spring 208. After the hemodialysis tube is properly placed, the elastic force of the first spring 208 causes the rubber block 2011 on the fixed block 2010 to press tightly against the hemodialysis tube, further stabilizing the position of the hemodialysis tube. The rubber block 2011 is soft in texture, which can not only reliably fix the hemodialysis tube but also cause no damage to it. At this time, by rotating the placing plate two 202, the first magnet 203 and the second magnet 204 are made to fit together. The first magnet 203 and the second magnet 204 cooperate with each other and attract each other, keeping the placing plate two 202 stable. The placing groove two 206 on the placing plate two 202 then protects the hemodialysis tube. The anti-slip bumps 207 effectively prevent the hemodialysis tube from sliding or falling off due to vibration or patient pulling during use by increasing the friction between the inner wall of the placing groove and the hemodialysis tube. Thus, it is ensured that the hemodialysis tube is stably fixed in the placing groove.

[0037] By pulling the hemodialysis tube from the outlet of the placing and fixing mechanism 2 to the support block 303 and contacting the first sponge pad 304, when the pull rod 3010 is pulled, during the process of the pull rod 3010 moving outwards, the moving plate 308 connected to it slides outwards in the installation shell 307 against the elastic force of the second spring 3011, thereby driving the insertion rod 309 to move. By fixing the limit block 301 on the support plate 1 through the sliding rod 302, the second sponge pad 305 contacts the hemodialysis tube. At this time, the pull rod 3010 is released. Under the elastic force of the second spring 3011, the moving plate 308 moves back, and the insertion rod 309 is tightly inserted into the insertion slot 306, thus fixing the position of the sliding rod 302. The second sponge pad 305 at the bottom of the limit block 301 and the first sponge pad 304 at the top of the support block 303 can buffer and protect the hemodialysis tube, prevent the hemodialysis tube from being pinched, and at the same time can also increase the friction with the hemodialysis tube, further preventing the hemodialysis tube from displacing at this part.
