Description

Technical Field

[0001] The utility model relates to the technical field of blood purification, in particular to an arm fixing device for puncturing a blood purification indwelling needle. Background Technique

[0002] Blood purification treatment, also commonly known as artificial kidney or hemodialysis, is a kind of blood purification technology. It utilizes the principle of semipermeable membrane to remove various harmful and excessive metabolic wastes and excessive electrolytes from the body through diffusion and convection, so as to achieve the purpose of purifying the blood and correcting the water and electrolyte and acid-base balance. The semipermeable membrane used in blood purification treatment has a thickness of 10-20 microns, and the average pore size on the membrane is 3 nanometers. Therefore, only small molecules with a molecular weight of less than 15,000 and some medium molecules can pass through, while macromolecules with a molecular weight greater than 35,000 cannot pass through. Therefore, proteins, pyrogens, viruses, bacteria, and blood cells are all non-permeable; most of the components in urine are water. To replace the kidney with an artificial kidney, a large amount of water must be removed from the blood. The artificial kidney can only use osmotic pressure and ultrafiltration pressure to achieve the purpose of removing excessive water. The artificial kidney, that is, the blood purification treatment device used, has all the above functions, so as to adjust the quality and quantity of blood to be close to the physiological state. At present, hemodialysis works through two blood tubes, which are the blood inlet tube and the blood outlet tube respectively. Both the blood inlet tube and the blood outlet tube are connected to the connectors of the dialysis indwelling needles on the patient's arm;

[0003] However, when performing blood purification on younger patients, it is often necessary to establish arteriovenous vascular access at the patient's wrist and elbow joints. However, due to their young age, children may not cooperate during the treatment process, which will lead to poor blood flow. This will not only affect the treatment effect of the children, but also cause the machine to repeatedly alarm and pause, thus increasing the coagulation risk of the dialyzer;

[0004] To solve the above problems, an arm fixing device for puncturing a blood purification indwelling needle is proposed in this application. Content of the Utility Model

[0005] The utility model aims to provide an arm fixing device for puncturing a blood purification indwelling needle, which is mainly used to solve the problem that at present, arteriovenous vascular access needs to be established at the patient's wrist and elbow joints, and due to their young age, children may not cooperate during the treatment process, which will lead to poor blood flow. This will not only affect the treatment effect of the children, but also cause the machine to repeatedly alarm and pause, thus increasing the coagulation risk of the dialyzer.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] An arm fixing device for puncturing an indwelling needle for blood purification, comprising a first support block, one end of the first support block is hinged with a second support block, one end of the bottom of the first support block close to the second support block is fixedly connected with an adjusting component, one end of the first support block far from the second support block is fixedly connected with a palm fixing component, one side of the tops of the first support block and the second support block is fixedly connected with a first strap, one side of the first strap is fixedly connected with a hook surface of a magic tape, and one side of the first support block and the second support block far from the first strap is fixedly connected with a loop surface of a magic tape that adheres to the hook surface of the magic tape.

[0008] The working principle and beneficial effects of the present utility model:

[0009] 1. Working principle: When using this device, place the part of the child's arm below the elbow joint on the first support block, then the second support block can be rotated through the adjusting component so that its top fits with the part of the arm above the elbow joint. Then, the first support block and the second support block can be fixed on the child's arm through the first strap. The palm of the child can be fixed through the palm fixing component. Then, the device is fixed on the railing beside the nursing bed through the clamping component, and the device can be used normally.

[0010] 2. Beneficial effects: The second support block hinged at one end of the first support block can adjust the angle of the second support block through the adjusting component. In this way, when the first support block and the second support block are fixed on the child's arm, the arm can be in a bent state, making the child's arm more comfortable. The palm of the child can be fixed through the palm fixing component, and then the device is fixed on the railing beside the nursing bed through the clamping component. The advantage of this setting is that it can effectively prevent the blood flow from being blocked due to the child's arm moving randomly during the blood purification treatment.

[0011] Preferably, the adjusting component includes an L-shaped block fixedly connected to one end of the bottom of the first support block close to the second support block. A threaded rod passes through the L-shaped block, and the threaded rod is in threaded connection with the L-shaped block. The upper end of the threaded rod is rotatably connected to a rotating rod.

A T-shaped groove matching the T-shaped block is opened at the bottom of the second support block. The connecting block is rotatably connected to the rotating rod. When using this device, the part of the child's arm below the elbow joint is fixed on the first support block through the first strap, and then the threaded rod is rotated to push the second support block to rotate upward. When its top fits with the part of the arm above the elbow joint, it is fixed through the first strap. In this way, when the first support block and the second support block are fixed on the child's arm, the arm can be in a bent state, making the child's arm more comfortable.

[0012] Preferably, the palm fixing assembly includes a fixing plate fixedly connected to one end of the first support block away from the second support block. On one side of the top of the fixing plate, a second strap is fixedly connected. One end of the second strap is fixedly connected with a hook-and-loop fastener's fuzzy surface, and on the bottom of the fixing plate, a hook-and-loop fastener's hook surface adhered to the fuzzy surface is fixedly connected. After the medical staff fix both the first support block and the second support block to the child's arm, the child's palm can be placed on the fixing plate and the child's palm can be fixed by the second strap, which can effectively prevent the child's palm from being in a bent state and causing poor blood circulation.

[0013] Preferably, the clamping assembly includes symmetric fixing blocks fixedly connected to both sides of the bottom of the first support block. A limit bolt passes through one of the fixing blocks, and the limit bolt is threadedly connected to the fixing block. One end of the limit bolt is fixedly connected with a knob, and the other end is rotatably connected to a clamping plate. The top of the clamping plate is slidably connected to the first support block. When the device is in use, the fixing block and the clamping plate are clamped on the railing beside the nursing bed. Rotating the knob can make the limit bolt drive the clamping plate to move towards the railing. When the fixing block and the clamping plate clamp the railing tightly, it can play a good fixing role for the device, so that the device has high stability during use.

[0014] Preferably, arc-shaped grooves are formed on the tops of both the first support block and the second support block, and sponge pads are fixedly connected to the inner walls of the arc-shaped grooves. Through the arc-shaped grooves formed on the tops of the first support block and the second support block, the patient's arm can be more closely attached to the first support block and the second support block. Through the sponge pads arranged on the inner walls of the arc-shaped grooves, the comfort of the patient's arm can be effectively improved.

[0015] Preferably, a rubber pad is fixedly connected to the side of the clamping plate away from the limit bolt, and anti-slip lines are formed on the rubber pad. When the fixing block and the rubber pad on one side of the clamping plate clamp the railing tightly, through the anti-slip lines formed on the rubber pad, the friction between the clamping plate and the railing can be increased, so as to play a better clamping and fixing effect on the device.

[0016] Preferably, the knob is in a plum blossom shape, and an anti-slip sleeve is sleeved on the outer wall of the knob. By setting the shape of the knob to a plum blossom shape, it can make it easier and more labor-saving for people to rotate the knob. Through the anti-slip sleeve sleeved on the outer wall of the knob, the friction between the medical staff's hand and the knob can be increased, so as to effectively prevent the hand from slipping when people rotate the knob.
