Description

Technical Field

[0001] This utility model relates to the field of clinical auxiliary frame technology, specifically a clinical auxiliary frame for hemodialysis with a limiting function. Background Technology

[0002] Clinical support frames for hemodialysis are primarily used to precisely limit the position or range of movement of key components involved in the hemodialysis process (such as dialysis tubing, puncture needles, and vascular access devices). Through preset limiting structures or adjustment mechanisms, they prevent the risk of tubing twisting, dislodgement, or puncture site damage (such as bleeding or hematoma) caused by accidental pulling, displacement, or excessive movement. This helps maintain the continuity and safety of hemodialysis treatment and provides stable support for clinical operations.

[0003] However, existing clinical support frames for hemodialysis have the following drawbacks: (1) The existing clinical auxiliary frame for hemodialysis has a weak function in reducing the risk of injury to the puncture site. Due to the displacement of the patient's limb position during dialysis, the puncture needle may rub or scratch the blood vessel wall, which increases the probability of complications. (2) Existing clinical auxiliary frames for hemodialysis prevent limbs from hanging in the air, which reduces patient comfort. Due to fatigue from limbs hanging in the air, prolonged fixation can cause muscle stiffness or coldness, resulting in reduced patient comfort and a tendency to develop resistance. Utility Model Content

[0004] The purpose of this invention is to provide a clinical auxiliary frame for hemodialysis with a limiting function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clinical auxiliary frame for hemodialysis with a limiting function, comprising: a fixing plate, a limiting component, and a supporting component. A fixing ring is fixedly connected to the top of the fixing plate. A limiting rod is rotatably connected inside the fixing ring. A limiting ring is fixedly connected to the outer surface of the limiting rod. A first limiting block is fixedly connected to one side of the bottom of the limiting ring. A second limiting block is provided on one side of the first limiting block. A connecting plate is fixedly connected to one side of the second limiting block. A first telescopic rod is fixedly connected to one side of the connecting plate. A first spring is sleeved on the outer surface of the first telescopic rod. A fixing frame is fixedly connected to the top of one side of the fixing ring. A clamping frame is fixedly connected to the bottom of the fixing plate, and an extension plate is fixedly connected to the top of one side of the clamping frame. A connecting slot is opened at the top of the extension plate, and a sub-hook and loop fastener is fixedly connected inside the connecting slot. A female hook and loop fastener is provided on the top of the sub-hook and loop fastener, and a pad is fixedly connected to the top of the female hook and loop fastener. A clamping screw is threaded inside the clamping frame, and a clamping piece is fixedly connected to the top of the clamping screw.

[0006] Optionally, the inner bottom wall of the fixed frame is provided with a fixing groove, and the end of the first telescopic rod away from the connecting ring is connected to the fixed frame through the fixing groove, thereby fixing the first telescopic rod to the fixed frame.

[0007] Optionally, one end of the first spring is fixedly connected to the inner bottom wall of the fixed frame, and the other end of the first spring is fixedly connected to the side of the connecting plate away from the second limiting block. Through the connection between the first spring, the fixed frame, and the connecting plate, the fixed frame supports and fixes one end of the first spring. When the first spring extends or retracts, the connecting plate moves together.

[0008] Optionally, a second telescopic rod is fixedly connected to the inner top wall of the limiting ring, a second spring is sleeved on the outer surface of the second telescopic rod, and a protective pad is fixedly connected to the bottom of the second telescopic rod. The cooperation of the second telescopic rod, the second spring, and the protective pad can prevent wear between the limb and the fixing ring and the limiting ring.

[0009] Optionally, one end of the second spring is fixedly connected to the inner top wall of the limiting ring, and the other end of the second spring is fixedly connected to the top of the protective pad. Through the connection between the second spring, the limiting ring, and the protective pad, the limiting ring supports and fixes one end of the second spring. When the second spring extends or retracts, it will drive the protective pad to move together.

[0010] Optionally, the protective pad is made of silicone, and the mat is made of cotton cloth. The silicone material of the protective pad can protect the surface of the limbs, and the cotton material of the mat can provide a certain degree of warmth.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This hemodialysis clinical auxiliary frame with a limiting function, through the setting of the limiting component, allows the limb to be placed on the inner wall of the fixed ring during use. After rotating the limiting ring, the limiting rod simultaneously limits the rotation angle of the limiting ring. When the bottom of the limiting ring rotates to fit against the inner wall of the fixed ring, the first limiting block squeezes the second limiting block and drives the first telescopic rod and the first spring to contract. Then, the first spring rebounds and drives the second limiting block to lock the first limiting block, stabilizing the position of the limiting ring. In conjunction with the fixed ring, it stabilizes and limits the position of the limb, thereby reducing the risk of damage to the puncture site and avoiding displacement of the patient's limb position during dialysis, friction or scratching of the blood vessel wall by the puncture needle, which could increase the probability of complications.

[0012] 2. This clinical auxiliary frame for hemodialysis with a limiting function, through the setting of the support components, allows for stable use by attaching the clamping frame to the handrail, then rotating the clamping screw to move the clamping plate, and finally attaching the male and female Velcro straps to connect the pad and extension plate. This provides support for the patient's limbs and is suitable for use in low-temperature environments or by elderly patients. It prevents limbs from dangling, increases patient comfort, and avoids fatigue from limbs being suspended, muscle stiffness from prolonged fixation, or cold exposure, which can reduce patient comfort and lead to resistance.

A fixing ring 201 is fixedly connected to the top of the fixing plate 1. A limiting rod 202 is rotatably connected inside the fixing ring 201. A limiting ring 203 is fixedly connected to the outer surface of the limiting rod 202. A first limiting block 204 is fixedly connected to one side of the bottom of the limiting ring 203. A second limiting block 205 is provided on one side of the first limiting block 204. A connecting plate 206 is fixedly connected to one side of the second limiting block 205. A first telescopic rod 207 is fixedly connected to one side of the connecting plate 206. A first spring 208 is fitted onto the outer surface of the rod 207. A fixed frame 209 is fixedly connected to the top of one side of the fixed ring 201. After the limb is placed on the inner wall of the fixed ring 201, the limiting ring 203 is rotated. At the same time, the limiting rod 202 limits the rotation angle of the limiting ring 203. When the bottom of the limiting ring 203 rotates to fit against the inner wall of the fixed ring 201, the first limiting block 204 presses against the second limiting block 205 and causes the first telescopic rod 207 and the first spring 208 to retract. Then, the first spring 208 rebounds and causes the second limiting block 205 to lock the first limiting block 204, stabilizing the position of the limiting ring 203. Together with the fixed ring 201, it stably limits the position of the limb. Both the first limiting block 204 and the second limiting block 205 are right-angled trapezoidal structures in shape and size. The first limiting block 204 has a 30° inclined surface angle, a height of 10mm, an upper base width of 8mm, and a lower base width of 15mm. The second limiting block 205 has a complementary inclined surface to the first limiting block 204, a matching angle of 30°, and the same size. A clamping frame 301 is fixedly connected to the bottom of the fixed plate 1. An extension plate 302 is fixedly connected to the top of one side of the clamping frame 301. A connecting slot 303 is opened on the top of the extension plate 302. A sub-hook and loop fastener 304 is fixedly connected inside the connecting slot 303. A female hook and loop fastener 305 is provided on the top of the sub-hook and loop fastener 304. A pad 306 is fixedly connected to the top of the female hook and loop fastener 305. A clamping screw 307 is threadedly connected inside the clamping frame 301. A clamping piece 308 is fixedly connected to the top of the clamping screw 307. The clamping frame 301 is attached to the armrest, and then the clamping screw 307 is rotated to move the clamping piece 308, so that the position of the clamping frame 301 is kept stable. Then the sub-hook and loop fastener 304 and the female hook and loop fastener 305 are attached to connect the pad 306 and the extension plate 302. This can support the bottom of the patient's limb and is suitable for use in low temperature environments or for elderly patients. One hook and loop fastener each are provided, with an adhesive strength ≥5N / cm. 2 Ensure that the pad 306 and the extension plate 302 can withstand a force of 5kg without falling off after being connected; The inner bottom wall of the fixed frame 209 is provided with a fixing groove. The end of the first telescopic rod 207 away from the connecting ring is connected to the fixed frame 209 through the fixing groove. The fixing groove connects and fixes the first telescopic rod 207 to the fixed frame 209. One end of the first spring 208 is fixedly connected to the inner bottom wall of the fixed frame 209, and the other end of the first spring 208 is fixedly connected to the side of the connecting plate 206 away from the second limiting block 205. Through the connection between the first spring 208, the fixed frame 209, and the connecting plate 206, the fixed frame 209 supports and fixes one end of the first spring 208. When the first spring 208 extends or retracts, it will move together with the connecting plate 206. The inner top wall of the limiting ring 203 is fixedly connected to the second telescopic rod 4, the outer surface of the second telescopic rod 4 is sleeved with the second spring 5, and the bottom of the second telescopic rod 4 is fixedly connected to the protective pad 6. The cooperation of the second telescopic rod 4, the second spring 5 and the protective pad 6 can prevent wear between the limb and the fixing ring 201 and the limiting ring 203. One end of the second spring 5 is fixedly connected to the inner top wall of the limiting ring 203, and the other end of the second spring 5 is fixedly connected to the top of the protective pad 6. Through the connection between the second spring 5, the limiting ring 203, and the protective pad 6, the limiting ring 203 supports and fixes one end of the second spring 5. When the second spring 5 extends or retracts, it will drive the protective pad 6 to move together. The protective pad 6 is made of silicone, and the pad 306 is made of cotton cloth. Because the protective pad 6 is made of silicone, it can protect the surface of the limbs, and because the pad 306 is made of cotton cloth, it can provide a certain degree of warmth.

[0017] In this invention, the working steps of the device are as follows: First step: After placing the limb on the inner wall of the fixing ring 201, rotate the limiting ring 203. At the same time, the limiting rod 202 limits the rotation angle of the limiting ring 203. When the bottom of the limiting ring 203 rotates to fit against the inner wall of the fixing ring 201, the first limiting block 204 presses against the second limiting block 205 and causes the first telescopic rod 207 and the first spring 208 to retract. Then, the first spring 208 rebounds and causes the second limiting block 205 to lock the first limiting block 204, thus stabilizing the position of the limiting ring 203. Together with the fixing ring 201, the position of the limb is stably limited.

[0018] The second step is to attach the clamping frame 301 to the armrest, then rotate the clamping screw 307 to move the clamping piece 308, so that the position of the clamping frame 301 is stable. Then attach the child hook and loop fastener 304 to the mother hook and loop fastener 305, so that the pad 306 and the extension plate 302 are connected, which can support the bottom of the patient's limbs and is suitable for use in low temperature environments or elderly patients.

[0019] The third step: The fixing groove connects and fixes the first telescopic rod 207 to the fixing frame 209. The first spring 208 is connected to the fixing frame 209 and the connecting plate 206. The fixing frame 209 supports and fixes one end of the first spring 208. When the first spring 208 extends or retracts, the connecting plate 206 moves together. The cooperation of the second telescopic rod 4, the second spring 5 and the protective pad 6 can prevent wear between the limb and the fixing ring 201 and the limiting ring 203. The second spring 5 is connected to the limiting ring 203 and the protective pad 6. The limiting ring 203 supports and fixes one end of the second spring 5. When the second spring 5 extends or retracts, it will drive the protective pad 6 to move together. Because the protective pad 6 is made of silicone, it can protect the surface of the limb. Because the pad 306 is made of cotton cloth, it can play a certain role in keeping warm.
