Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a forearm and wrist adjusting fixer for radial artery puncture and catheterization. Background technique

[0002] Radial artery puncture is generally used to observe vital signs during surgical anesthesia, and belongs to the project of invasive arterial blood pressure monitoring.

[0003] At present, there is no suitable radial artery puncture stent clinically. During the clinical operation or in the intensive care unit, it is found that the position of the patient is not easy to fix when the radial artery is punctured before the operation, and the puncture is difficult. Improper body position causes the catheter for puncture and catheterization to be discounted and unsmooth, which affects the blood pressure measurement results of the radial artery, or even fails to measure the value, which affects the operation process.

[0004] Clinically, it is fixed with a fixed lace...

Examples

Embodiment

[0045] Embodiment: When using the forearm immobilizer, first snap the straight edge of the arm immobilizer plate 4 into the bottom of the mattress of the operating bed, and realize the fixing of the device by the hardness of the mattress itself, so that the whole device can be fixed on the operating bed, avoiding Improper wrist fixation leads to the fall of the radial artery puncture needle, reducing the number of punctures for the patient, and starting the controller to drive the heating wire to heat to ensure the comfort of the patient; then open the upper cover 2 of the arm, and put the hand into the lower cover 3 of the arm into the half-finger glove 1, and fasten the upper arm cover 2 and the lower arm cover 3 to avoid iatrogenic pressure injury caused by improper pressing and fixing, and increase potential damage risk, provide a guarantee for accurate blood pressure measurement, and reduce postoperative complications such as joint stiffness or strain caused by improper wr...
