Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary products, and more specifically, particularly to a skin traction device for puncture. Background Art

[0002] When performing intravenous puncture on the elderly, due to their relatively loose skin, the puncture process requires medical staff to flatten the skin at the location where puncture is required with one hand in order to fix the blood vessel and ensure that the blood vessel does not shift or move. Then use the other hand to disinfect the skin and puncture the blood vessel at that location. During the whole process, medical staff need to flatten the patient's skin with one hand, so that they can only perform the puncture operation with one hand. Such an operation process is likely to affect the medical staff's blood vessel puncture effect, resulting in an increase in the puncture failure rate, increasing the workload of medical staff, and also causing pain to patients.

[0003] There are some existing devices for pulling the skin, such as patent number CN202210793217.7, the patent name is a skin tightening device for puncture, the device includes a patch, a support frame and a traction mechanism, the limb to be punctured is placed on the placement surface with the skin to be punctured facing upwards, and then the two patches are respectively pasted on both sides of the limb, and then the traction rope is wound on the winding wheel. Since the traction mechanism is located below the support frame, the traction rope can pull the patch at the end to move downward, so that the puncture surface of the skin can be effectively tensioned, and the locking assembly can lock the winding wheel on the mounting frame when the skin is tightened, so that the traction mechanism maintains the tension of the skin puncture surface. However, the device needs to be placed on the placement surface of the treatment table for use, which is inconvenient to use, not practical enough, and the structure of the device is relatively complicated. Therefore, it is urgent to design a skin traction device that is convenient for puncture to solve the above problems. Utility Model Content

A traction belt 3 is provided between the fixing belt 1 and the skin fixing patch 2, and the lower end of the traction belt 3 is fixedly connected to the skin fixing patch 2. A traction and fixing structure for clamping and fixing the traction belt 3 is provided between the fixing belt 1 and the traction belt 3. The skin fixing patch 2 can be used to stretch the patient's loose skin to the left and right, and the traction belt 3 generates a traction force on the skin fixing patch 2 toward the fixing belt 1, so as to achieve the effect of flattening the patient's skin near the puncture position, making it convenient for medical staff to puncture the patient's blood vessels, with high work efficiency and high puncture success rate. The traction fixing structure includes a guide cylinder 6 and a pressing block 7, the lower end of the guide cylinder 6 is fixedly connected to the fixing belt 1, the lower part of the pressing block 7 extends into the guide cylinder 6 and is slidably connected to the guide cylinder 6, a spring 8 is provided between the lower end of the pressing block 7 and the fixing belt 1, the upper and lower ends of the spring 8 are respectively fixedly connected to the pressing block 7 and the fixing belt 1, a pair of through holes 9 are symmetrically provided on the left and right side walls of the guide cylinder 6, a through groove 10 is provided at the lower part of the pressing block 7 from left to right, the right end of the traction belt 3 passes through the through hole 9 on the left, the through groove 10 and the through hole 9 on the right in sequence, and then extends out of the guide cylinder 6, and the traction fixing structure is used to fix the fixed The upper end of the fixed belt 1 is fixed and pulled. If the pressing block 7 is pressed down until the through groove 10 is in a straight line with the pair of conducting holes 9, the pair of conducting holes 9 will no longer produce pressure on the traction belt 3. The traction belt 3 can move along the extension direction of the through groove 10 to achieve the effect of adjusting the distance between the fixed belt 1 and the skin fixing patch 2. After the distance adjustment is completed, the pressing block 7 is released. At this time, the spring 8 located below the pressing block 7 will produce an upward thrust to it, pushing the pressing block 7 to move upward, and the pair of conducting holes 9 will clamp the two ends of the traction belt 3 extending out of the guide cylinder 6 to prevent the pressing block 7 from rising. The pressing block 7 and the pair of conducting holes 9 cooperate with each other to achieve the compression and fixation of the traction belt 3. After the injection is completed, the fixed belt 1 in the traction device can also be used as a tourniquet, which is tied and fixed on the outside of the puncture point so that the fixed belt 1 can compress the puncture point to achieve compression and hemostasis, which is convenient to use.

[0024] Furthermore, the fitting structure includes a Velcro sub-tie 4 and a Velcro mother-tie 5 respectively arranged at two ends of the fixing belt 1, and the Velcro sub-tie 4 and the Velcro mother-tie 5 cooperate with each other to achieve fitting and fixation.

[0025] Furthermore, the length of the magic mother patch 5 is greater than that of the magic sub-patch 4, and the magic sub-patch 4 is attached to different positions of the magic mother patch 5, so that the fixing belt 1 can be fixed on the arms of patients with different arm sizes.
