Description

Technical Field

[0001] The present invention relates to the technical field of kidney dialysis auxiliary equipment, and specifically relates to a dialysis auxiliary equipment for nephrology. Background Art

[0002] With the continuous development of social economy, the incidence of chronic kidney disease has been increasing year by year, and the number of patients receiving dialysis treatment has been continuously growing. As an important supporting tool in the treatment process, the performance of the dialysis auxiliary equipment for nephrology directly affects the treatment experience and safety of patients.

[0003] However, the traditional dialysis auxiliary equipment for nephrology relies on manual strap adjustment, which is not convenient to ensure uniform pressure distribution on both sides. It is easy to cause vascular compression due to excessive tightness on one side or pipeline displacement due to excessive looseness. Moreover, the straps are likely to become loose during the treatment activities of patients, and manual adjustment is required repeatedly, increasing the operation complexity and puncture risk. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the present invention provides a dialysis auxiliary equipment for nephrology, which solves the problem that the traditional dialysis auxiliary equipment for nephrology relies on manual strap adjustment.

[0006] (2) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0008] A dialysis auxiliary equipment for nephrology includes a tensioning component and a connection component. The tensioning component includes a main body box, and the connection component includes a connecting plate. One side of both ends of the outer wall of the connecting plate is rotatably connected with a rotating rod. Both ends of the other side of the inner wall of the main body box are rotatably connected with a worm gear. One side of each worm gear is fixedly connected with a first gear, and the other side of each rotating rod is fixedly connected with a second gear;

[0009] A chuck is fixedly connected to the rod body of the rotating rod, and an elastic cord is arranged on the inner wall of the chuck. One side of the lower part of the outer wall of the connecting plate is fixedly connected with a positioning plate. The front end and the rear end of the upper surface of one side of the positioning plate are both hingedly connected with a connecting soft plate. A card slot is opened at the upper end of the connecting plate. A plurality of sliding grooves are opened on both sides of the inner wall of the card slot. A sliding plate is slidably connected to the inner wall of the sliding groove. One side of each sliding plate close to the center of the card slot is fixedly connected with a soft plate. A fixing block is fixedly connected to the rear end of the upper surface of each soft plate. A threaded rod is fixedly connected to the adjacent side of each fixing block, and a bidirectional threaded sleeve is threadedly connected to the adjacent side of each threaded rod;

[0010] Through the above technical solution, the combined design of the bidirectional threaded sleeve and the threaded rod drives the threaded rod to move towards each other by rotating the sleeve, realizing the linear adjustment of the soft board spacing, being compatible with devices such as mobile phones. The soft board is made of silica gel material, providing frictional force when clamping, and cooperating with the anti-slip pattern design, which can not only stabilize the device but also avoid surface scratches. The clamping position is located in the area flush with the upper end of the connecting plate, and the patient can operate without lowering the head, reducing cervical fatigue. The sliding fit design of the sliding plate and the sliding groove ensures the stability of the device during dialysis, and even if the patient's arm shakes slightly, it can still remain stable.

[0011] Preferably, on the other side of the front end of the upper surface of the main body box, a protective shell is fixedly connected. A servo motor is arranged on the inner wall of the protective shell, and on the other side of the front end of the inner top surface of the main body box, a worm is rotatably connected;

[0012] Through the above technical solution, the protective shell can provide protection for the servo motor, preventing foreign impurities such as dust and water vapor in the outside world from entering the motor interior, thereby prolonging the service life of the servo motor.

[0013] Preferably, tooth belts are sleeved on the outer walls of the other sides of the two first gears, and the first gears are meshed with the adjacent second gears;

[0014] Through the above technical solution, the setting of the tooth belts realizes the synchronous rotation of the two first gears, ensuring the consistency and stability of the transmission on both sides, enabling the subsequent tightening force on the arm to be evenly distributed on both sides of the arm, avoiding the situation of being too tight or too loose on one side, and improving the effect of arm fixation.

[0015] Preferably, the other sides of the lower ends of the connecting soft boards are slidably connected to the inner walls of the other sides of the positioning plates. The two elastic ropes pass through the connecting plate into the interior of the positioning plate and are fixedly connected to the lower ends of the corresponding connecting soft boards;

[0016] Through the above technical solution, the sliding connection mode between the connecting soft board and the positioning plate enables the connecting soft board to move flexibly within the positioning plate, facilitating the tightening operation on the arm according to actual needs. The fixed connection between the elastic rope and the connecting soft board can effectively transmit the pulling force to the connecting soft board when the chuck rotates and winds the elastic rope, thereby realizing the movement of the connecting soft board and reliably tightening both ends of the arm, ensuring the stability of the arm during the treatment process.

[0017] Preferably, the other side of the outer wall of the connecting plate is fixedly connected to the outer wall of the main body box;

[0018] Through the above technical solution, the fixed connection between the connecting plate and the main body box enhances the stability and integrity of the entire structure, providing a stable support foundation for components such as the connecting soft board and the positioning plate.

[0019] Preferably, the output end of the servo motor passes through the main body box and is fixedly connected to the upper end of the worm, and the lower end of the worm is meshed with the outer wall of the front worm wheel;

[0020] Through the above technical solution, the fixed connection between the servo motor and the worm can efficiently transmit the power of the motor to the worm, and the meshing of the worm and the worm wheel realizes the conversion of motion form and speed.

[0021] (III) Beneficial effects

[0022] The present invention provides a dialysis auxiliary device for kidney medicine, which has the following beneficial effects:

[0023] 1. The present invention provides a dialysis auxiliary device for renal internal medicine. By driving the worm and worm wheel with the toothed belt synchronously through the servo motor, the chucks on both sides can rotate at the same speed, ensuring the balanced tension of the elastic rope on the connecting soft plate. Compared with the traditional manual binding strap, this structure can avoid vascular compression caused by unilateral over-tightening or pipeline displacement caused by over-loosening, so as to improve the uniformity of arm force. The self-locking characteristics of the worm and worm wheel (the helix angle of the worm wheel is less than the friction angle) can prevent accidental loosening caused by the patient's activities during treatment, and at the same time allow stepless tightness adjustment through the driving motor.

[0024] 2. The present invention provides a dialysis auxiliary device for renal internal medicine, with a combination design of a bidirectional threaded sleeve and a threaded rod. The threaded rod is driven to move toward each other by rotating the sleeve to achieve linear adjustment of the spacing between soft plates. The device is compatible with mobile phones and other devices. The soft plate is made of silicone material, and the friction provided when clamped, combined with the anti-slip pattern design, can stabilize the device and avoid surface scratches. The clamping position is located at the line of sight of the upper end of the connecting plate. The patient can operate it without lowering his head, reducing cervical fatigue. The sliding cooperation design of the slide plate and the slide groove ensures the stability of the device during dialysis, and it can remain stable even if the patient's arm shakes slightly.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] As Figure 1-10 shown, the embodiments of the present invention provide;

[0042] A dialysis assistance device for the department of nephrology, including a tightening component 1 and a connection component 2. The tightening component 1 includes a main body box 111. The connection component 2 includes a connection plate 201. One side of both ends of the outer wall of the connection plate 201 is rotatably connected to a rotating rod 108. Both ends of the other side of the inner wall of the main body box 111 are rotatably connected to a worm gear 104. A first gear 105 is fixedly connected to one side of each worm gear 104. A second gear 107 is fixedly connected to the other side of each rotating rod 108;

[0043] The rod body of the rotating rod 108 is fixedly connected with a chuck 109. An elastic cord 110 is arranged on the inner wall of the chuck 109. One side of the lower part of the outer wall of the connecting plate 201 is fixedly connected with a positioning plate 4. The front end and the rear end of the upper surface of one side of the positioning plate 4 are both hinged with a connecting soft plate 3. A clamping groove 202 is opened at the upper end of the connecting plate 201. A plurality of sliding grooves 203 are opened on both sides of the inner wall of the clamping groove 202. A sliding plate 205 is slidably connected to the inner wall of the sliding groove 203. One side of the sliding plate 205 close to the center of the clamping groove 202 is fixedly connected with a soft plate 204. The rear ends of the upper surfaces of the soft plates 204 are both fixedly connected with fixing blocks 207. The adjacent sides of the fixing blocks 207 are fixedly connected with threaded rods 208. The adjacent sides of the threaded rods 208 are both threadedly connected with a double-threaded sleeve 206;

[0044] The combined design of the double-threaded sleeve 206 and the threaded rod 208 drives the threaded rods 208 to move towards each other by rotating the sleeve, realizing the linear adjustment of the distance between the soft plates 204, which is compatible with devices such as mobile phones. The soft plates 204 are made of silica gel material, providing friction when clamping, and cooperating with the anti-slip pattern design, which can not only stabilize the device but also avoid surface scratches. The clamping position is located in the area at the same level as the line of sight at the upper end of the connecting plate 201, so that the patient can operate without lowering the head, reducing cervical fatigue. The sliding fit design of the sliding plate 205 and the sliding groove 203 ensures the stability of the device during dialysis, and even if the patient's arm shakes slightly, it can still be kept stable.

[0045] On the other side of the front end of the upper surface of the main body box 111, a protective shell 101 is fixedly connected. A servo motor 102 is arranged on the inner wall of the protective shell 101. On the other side of the front end of the inner top surface of the main body box 111, a worm 103 is rotatably connected. The protective shell 101 can provide protection for the servo motor 102, preventing external dust, water vapor and other impurities from entering the motor interior, thereby prolonging the service life of the servo motor 102. Tooth belts 106 are sleeved on the outer walls of the other sides of the two first gears 105. The first gears 105 are both meshed with the adjacent second gears 107. The arrangement of the tooth belts 106 realizes the synchronous rotation of the two first gears 105, ensuring the consistency and stability of the transmission on both sides, so that the subsequent tightening force on the arm can be evenly distributed on both sides of the arm, avoiding the situation of being too tight or too loose on one side, and improving the effect of arm fixation.

[0046] The lower ends of the other sides of the connecting flexible boards 3 are all slidably connected to the inner walls of the other sides of the positioning plates 4. Two elastic ropes 110 pass through the connecting plate 201 to the inside of the positioning plate 4 and are fixedly connected to the lower ends of the corresponding connecting flexible boards 3. The sliding connection mode between the connecting flexible boards 3 and the positioning plates 4 enables the connecting flexible boards 3 to move flexibly within the positioning plates 4, facilitating the tightening operation of the arms according to actual needs. The fixed connection between the elastic ropes 110 and the connecting flexible boards 3 can effectively transmit the pulling force to the connecting flexible boards 3 when the chuck 109 rotates and winds the elastic ropes 110, thereby realizing the movement of the connecting flexible boards 3, reliably tightening both ends of the arms, and ensuring the stability of the arms during the treatment process.

[0047] The other side of the outer wall of the connecting plate 201 is fixedly connected to the outer wall of the main body box 111. The fixed connection between the connecting plate 201 and the main body box 111 enhances the stability and integrity of the entire structure. It provides a stable support foundation for components such as the connecting flexible boards 3 and the positioning plates 4. The output end of the servo motor 102 passes through the main body box 111 and is fixedly connected to the upper end of the worm 103. The lower end of the worm 103 meshes with the outer wall of the front end worm wheel 104. The fixed connection between the servo motor 102 and the worm 103 can efficiently transmit the power of the motor to the worm 103, and the meshing between the worm 103 and the worm wheel 104 realizes the conversion of the motion form and rotational speed.

[0048] Working principle: The patient places the arm on the positioning plate 4. The connecting flexible board 3 is slidably matched with the inner chute 203 of the positioning plate 4 through the hinge point and remains in a relaxed state. The external controller starts the servo motor 102. The output shaft of the servo motor 102 drives the worm 103 to rotate. The worm 103 meshes with the worm wheel 104. The first gear 105 coaxially fixed to the worm wheel 104 synchronously drives the first gear 105 on the opposite side through the toothed belt 106 to ensure that the transmission on both sides is isochronous and in the same direction. The tension of the toothed belt 106 can be regularly maintained through the adjusting device;

[0049] The first gear 105 meshes externally with the second gear 107, driving the rotating rod 108 to rotate, driving the chuck 109 to wind the elastic rope 110. After the elastic rope 110 passes through the guiding hole of the connecting plate 201, it pulls the connecting flexible board 3 to slide along the chute 203 of the positioning plate 4, realizing the two-way synchronous tightening of both ends of the arm. The self-locking characteristic of the worm 103 and the worm wheel 104 prevents loosening. The arc-shaped curved surface design of the positioning plate 4 and the sliding fit with the connecting flexible board 3 disperse the local pressure, avoiding blood vessel compression;

[0050] Place the mobile phone in the card slot 202 at the upper end of the connecting plate 201. The sliding grooves 203 on both sides of the card slot 202 are slidably connected to the flexible board 204. Rotate the bidirectional threaded sleeve 206 to drive the threaded rods 208 to move towards each other. The fixing blocks 207 drive the flexible board 204 to slide along the sliding grooves 203, realizing the clamping and fixing with an adjustable stroke. The wavy silica gel pad on the inner side of the flexible board 204 and the multi-point convex point support ensure the stability of the mobile phone at a reasonable inclination angle. The ergonomic inclination design of the clamping surface reduces cervical fatigue.
