Description

Technical Field

[0001] The present invention relates to the technical field of hemodialysis, and specifically to a combined protection device for hemodialysis. Background Art

[0002] Hemodialysis, abbreviated as HD, is commonly known as "artificial kidney" or "kidney dialysis". It is an important blood purification technology widely used in patients with renal failure. The principle of hemodialysis is based on a semipermeable membrane. By utilizing the selective permeability of the semipermeable membrane, waste products, excessive electrolytes, and excess water in the blood are allowed to pass through the membrane and exchange with the dialysate, thereby being excreted from the body. This process can not only effectively remove harmful metabolic products accumulated in the body, such as urea and creatinine, but also regulate the body's water balance, preventing edema and dehydration.

[0003] Hemodialysis treatment usually takes a long time, usually lasting more than four hours. During this process, the patient needs to lie still or sit to ensure the smooth progress of the dialysis process. However, since the patient is prone to falling asleep, sitting up, or making other involuntary movements during the treatment, it is easy to cause the dialysis needle to fall off or pierce the blood vessel, resulting in blood extravasation and bleeding at the puncture site. This not only brings great pain to the patient but also increases the workload of medical staff. To reduce the occurrence of these problems, some fixing devices are currently available to help fix the patient's legs, prevent unnecessary movement during dialysis, ensure the stability of the puncture needle position, and ensure the smooth progress of the dialysis process. These fixing devices generally use straps, clamps, or support structures to restrain the patient's arm, reduce external interference, and lower the risk of needle detachment and puncture failure.

[0004] However, the existing leg fixing devices still have some significant deficiencies. In the prior art, many fixing devices usually use a bolt fixing mechanism to fix the entire protection device in the required position for use. Although this method provides a certain degree of stability, it also brings deficiencies in flexibility and adjustability. When adjustment is needed according to the actual situation of the patient, the existing fixing devices are often difficult to adjust quickly. For example, when fine-tuning the device during the treatment process to adapt to different patients, the device relying on bolt fixing requires a long time for disassembly, adjustment, and reinstallation, unable to meet the requirements of quick and flexible adjustment. In addition, the existing protection devices cannot perform timely dynamic fixation according to the patient's posture changes during dialysis. For example, when the patient accidentally falls asleep, turns, or slightly adjusts the leg position, the traditional fixing devices cannot effectively adapt to these changes, resulting in the deviation of the dialysis needle position, and even easily causing needle detachment and puncture failure, increasing the risk of dialysis treatment and the discomfort of the patient. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a combined protection device for hemodialysis, which solves the problem in the prior art that the protection device cannot be quickly installed and adjusted, thus increasing the labor intensity of medical staff.

The sliding grooves 13 are used for limiting the clamping blocks 8.

[0042] The two sliding grooves 13 can conveniently limit the clamping blocks 8, thereby preventing the clamping blocks 8 from shifting when moving.

[0043] Please refer to the appendix Figure 8, the fixing component includes a lower fixing block 6, the lower fixing block 6 is fixedly connected to the top of the connecting block 5, a limiting groove 31 is opened at the top of the lower fixing block 6, a limiting post 30 is slidably connected to the middle of the limiting groove 31, the top of the limiting post 30 is fixedly connected to an upper fixing block 7, one side of the upper fixing block 7 is fixedly connected to an upper adjusting block 27, a second tension spring 29 is fixedly connected to the bottom of the upper adjusting block 27, and one end of the second tension spring 29 away from the upper adjusting block 27 is fixedly connected to a lower adjusting block 28, and the lower adjusting block 28 is fixedly connected to one side of the lower fixing block 6.

[0047] Working principle: When the whole protection device is installed and fixed, manually drive the device to move, place the whole protection device at the position where it needs to be fixed. When the protection device is placed at the required position, the extrusion block 12 will be extruded. When the extrusion block 12 is extruded, it will also extrude the first spring 15. When the extrusion block 12 extrudes the first spring 15, it will drive the limiting plate 22 to move upward, so that the limiting plate 22 and the two clamping plates 21 are separated. After the limiting plate 22 and the two clamping plates 21 are separated, under the action of the two first tension springs 20, the first slider 16 and the second slider 18 can be pulled to move towards each other, and when the first slider 16 and the second slider 18 move, they will drive the two clamping blocks 8 to move simultaneously. When the two clamping blocks 8 move towards each other, they can clamp and fix the placed position;

[0048] When disassembling the protection device, manually press the second slider 18 and the second connecting plate 19 to move. When the second slider 18 and the second connecting plate 19 move, they can squeeze the first slider 16 and the second slider 18, causing the first slider 16 and the second slider 18 to move in opposite directions. When the first slider 16 and the second slider 18 move in opposite directions, they will drive the two clamping plates 21 to move simultaneously. When the two clamping plates 21 move, the first spring 15 will push the limiting plate 22 and the extrusion block 12 downward, causing the limiting plate 22 to be clamped with the two clamping plates 21. When the first slider 16 and the second slider 18 move in opposite directions, they will drive the two clamping blocks 8 to move in opposite directions simultaneously, so that the whole protection device can be disassembled.

[0049] When it is necessary to adjust according to the different leg positions and angles of the patient, manually move the dial 32 upward. When the dial 32 moves upward, it will drive the pull rod 33 to move upward simultaneously. When the pull rod 33 moves, it will pull the adjusting ring 34 to move. When the adjusting ring 34 moves, it will squeeze the second spring 37. While the adjusting ring 34 squeezes the second spring 37, it will drive the clamping rod 36 to move, causing the clamping rod 36 to disengage from the clamping groove 35. When the clamping rod 36 disengages from the clamping groove 35, the adjusting column 4 can be manually rotated. When the adjusting column 4 rotates, it can drive the lower fixing block 6 and the upper fixing block 7 to move simultaneously, so that the leg position and angle of the patient can be adjusted according to different situations.

[0050] When it is necessary to replace the lower fixing block 6 and the upper fixing block 7 according to the usage situation of the patient, manually move the extrusion plate 38. When the extrusion plate 38 moves, it will squeeze the compression spring 24. When the compression spring 24 is squeezed, it will drive the clamping groove 35 to move simultaneously, causing the clamping block 25 to disengage from the clamping slot 26. After the clamping block 25 disengages from the clamping slot 26, the lower fixing block 6 and the adjusting column 4 can be separated, so that the lower fixing block 6 and the upper fixing block 7 can be replaced according to the usage situation of the patient.

[0051] When fixing the patient's leg, manually pull the handle 10 upward. When the handle 10 moves upward, it will drive the upper fixing block 7 and the limiting column 30 to move upward simultaneously. When the upper fixing block 7 moves upward, it can drive the second pull spring 29 to stretch through the upper adjusting block 27, so that the upper fixing block 7 and the lower fixing block 6 are separated. After the upper fixing block 7 and the lower fixing block 6 are separated, the patient's leg can be placed between the upper fixing block 7 and the lower fixing block 6. After the placement is completed, release the handle 10. When releasing the handle 10, under the action of the second pull spring 29, the upper fixing block 7 can be pulled downward to connect and fix the patient's leg.
