Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a high-efficiency dialysis device for blood purification. Background Technology
[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves draining blood from the body and passing it through a dialyzer composed of numerous hollow fibers. The blood exchanges substances with an electrolyte solution (dialysis fluid) containing a concentration similar to that in the body through diffusion, ultrafiltration, adsorption, and convection within and outside the hollow fibers. This process removes metabolic waste products, maintains electrolyte and acid-base balance, and removes excess water. The purified blood is then returned to the body. The entire process is called hemodialysis.
[0003] During dialysis, many patients' arms are exposed, and in the cold winter, prolonged dialysis can cause their arms to become cold. Furthermore, due to the outflow of dialysis blood and the loss of temperature, patients may also feel cold all over and experience extreme discomfort. Therefore, when the body temperature is low, the blood circulation speed will also slow down and have an impact. Thus, a high-efficiency dialysis device for blood purification has been designed.

[0043] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0044] Example: According to the appendix of the instruction manual Figure 1-8 As shown, the working principle is as follows:
[0045] In use, it is supported by the pad 94 in the shim structure 9; and the support height of the first pad box 91 and the second pad box 93 can be adjusted by rotating the pad 94.
[0046] Then place the arm between the first arm support 11 of the first bearing structure 1 and the second arm support 21 of the second bearing structure 2, i.e., on the elastic band 5; when the arm is wide, adjust the exposed length of the limiting arm 3 between the first arm support 11 and the second arm support 21, and adjust it by using the tightening bolt 4 to limit it, and then stretch the elastic band 5 between the first band groove and the second band groove 104 to adjust the overall bearing width;
[0047] Then, flip the cover 7 over and fasten it. After adjusting the width, the end of the cover 7 with the magnet 8 will also move on the second arm support 21 and be limited by the attraction between the magnet 8 and the magnetic strip 6.
[0048] After powering or charging the battery 92, the first heating port 103 and the first heating plate 13 and the second heating plate 22 in the second heating port can be heated, and the first air supply unit 14 and the second air supply unit 24 can be driven to blow air. The air passes through the first heating port 103 and the second heating port from the outside and is heated. It is then convected and dispersed below the elastic band 5, heating the arm and the surrounding space at the same time. In addition, part of the temperature of the first heating plate 13 and the second heating plate 22 will be transferred to the inner wall of the adjacent first tube groove 105 and second tube groove 106 in the first arm support 11 and the second arm support 21.
[0049] After the blood delivery tubing is embedded in the first tubing groove 105 and the second tubing groove 106, the first tube-blocking claw 12 in the first bearing structure 1 and the second tube-blocking claw 23 in the second bearing structure 2 are rotated to block and limit the movement, thereby maintaining the temperature of the blood delivery tubing.
[0050] During the air supply process, the fan 143 on the air frame 141 is driven to quickly heat up the air passing between the two first heating plates 13 and the second heating plate 22 and blow it out. If it is hot in summer, the first heating plate 13 and the second heating plate 22 can be stopped to blow out a gentle breeze to cool down. Alternatively, the limit bolt 142 can be turned to unlock the air frame 141 and flip it outward to allow the fan 143 to blow air towards the patient.
[0051] When the patient's arm is long, the adapter rod 101 can be inserted into the storage port 107 with the help of the adapter bolt 102 to limit and fix it, thereby extending the use of the second arm support 21 in the two devices.
[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
