Description
Technical Field
[0001] The utility model relates to the technical field of radial artery puncture, in particular to a hand rest for facilitating radial artery puncture. Background Art
[0002] Radial artery puncture is a technique frequently used in clinical work. It can be used to monitor arterial blood pressure, interventional treatment, and blood tests. During the puncture process, the arm usually needs to be abducted and the wrist fully exposed to facilitate more convenient operation. Therefore, the arm position needs to be supported and fixed before the puncture operation.
[0003] The existing hand rest for facilitating radial artery puncture generally only plays a supporting role. During the puncture, medical staff need to hold the patient's palm to straighten the artery for subsequent puncture. This step requires additional medical staff to assist, which is not convenient for a single person to operate. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a hand rest that is convenient for radial artery puncture, so as to solve the technical problem that additional medical staff are needed to assist and it is not convenient for a single person to operate.

[0013] Furthermore, the bottom of the rubber block is connected to a first clamping plate through torsion rotation, and one end of the first clamping plate is fixedly connected to a first anti-slip pad.
[0014] By adopting the above technical solution, the first splint is connected by torque rotation at the bottom of the rubber block, so that the hand rest can be conveniently fixed on the edge of the bed or other flat surfaces, providing a stable operating platform to prevent the hand rest from moving during the puncture process, thereby ensuring the accuracy and safety of the puncture.
[0015] Furthermore, the forearm support has an arc-shaped structure, and the forearm support and the arc-shaped groove are adapted to each other.
[0016] By adopting the above technical solution, the forearm support is designed into an arc-shaped structure. This shape can better adapt to the natural curve of the patient's forearm and provide a more fitting and comfortable support. The arc-shaped structure can reduce the patient's discomfort during use and increase the comfort of use.
[0017] Furthermore, the sliding block is slidably connected to the dovetail groove, and the sliding block and the dovetail groove are adapted to each other.
[0018] By adopting the above technical solution, the sliding connection method of the sliding block and the dovetail groove allows the forearm support to slide smoothly on the rubber block, providing flexible arm support, so that medical staff can easily adjust the position of the forearm support according to puncture needs.

The arc groove 2 provided on the rubber block 1 and the forearm support 4 are used in combination to provide stable support for the patient's arm. The shape of the arc groove 2 and the forearm support 4 matches, ensuring the comfort and stability of the arm, the elastic band 6 fixedly connected on one side of the forearm support 4 and the slot 7 and the clip 8 on the other side can easily fix the patient's palm and turn it over to tighten the artery, which provides great convenience for the puncture operation. In addition, the material of the rubber block 1 ensures the comfort of the patient, and the sliding block 5 at the bottom of the forearm support 4 cooperates with the dovetail groove 3, so that the forearm support 4 can be flexibly rotated inside the arc groove 2, thereby meeting the arm length and puncture position requirements of different patients.
[0038] See also Figure 2 A clamping hole 9 is provided on the rubber block 1, and a plurality of clamping holes 9 are provided, and the plurality of clamping holes 9 are arranged equidistantly in a ring shape. By providing a plurality of clamping holes 9 on the rubber block 1, and these clamping holes are arranged equidistantly in a ring shape, more fixing options are provided for the hand rest, so that medical staff can flexibly choose to insert the left plug column 10 or the right plug column 12 into the appropriate clamping hole 9 according to actual needs, so as to achieve stable fixation of the forearm rest 4. At the same time, the clamping hole 9 increases the stability and reliability of the fixation, effectively preventing the accidental movement of the hand rest during the puncture process, which not only improves the accuracy of the puncture, but also ensures the safety and comfort of the patient.
[0039] See also Figure 1 and Figure 3 A left plug post 10 is arranged above the elastic band 6, and the left plug post 10 is slidably connected to the forearm support 4. A first spring 11 is arranged between the left plug post 10 and the forearm support 4. By arranging the left plug post 10 above the elastic band 6 and slidably connecting the left plug post 10 to the forearm support 4, such a design enables the left plug post 10 to be conveniently rotated when needed, thereby increasing the flexibility and convenience of use. At the same time, the first spring 11 arranged between the left plug post 10 and the forearm support 4 plays a role of buffering and resetting. When the left plug post 10 is moved or released, the first spring 11 can help it to reset smoothly, thereby maintaining the stability and reliability of the hand rest, which not only improves the practicability of the hand rest, but also ensures the comfort and safety of the patient during use.
