Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a device for elbow joint immobilization after brachial artery puncture. Background Art

[0002] Brachial artery puncture is an important medical procedure, especially widely used in cardiovascular medicine. However, after the operation, the elbow joint of the patient needs to be effectively immobilized to prevent complications such as bleeding, hematoma, and infection caused by movement. Traditional immobilization methods, such as using elastic bandages for fixation, although can limit the movement of the elbow joint to a certain extent, have limited immobilization effect and cannot meet the requirements of generalization and personalization. With the continuous progress of medical technology and the increasing demands of patients, the requirements for elbow joint immobilization devices after brachial artery puncture are also getting higher and higher. Therefore, it is particularly important to develop a new type of elbow joint immobilization device that can better adapt to individual differences of patients, improve the immobilization effect and is convenient for adjustment.

[0003] There are some existing elbow joint immobilization devices after brachial artery puncture hoping to solve this problem. The patent with the publication number CN111839873A discloses an elbow joint immobilization device after brachial artery puncture in cardiovascular medicine. When the arm is placed inside the support member, through the rotational cooperation of the rotating sleeve and the connecting rod, the support plate can be rotated, so that the distance between the two support plates can be adjusted according to the width of the patient's arm to clamp the arm; in addition, the extension plate can be pulled out from the placement groove, and by inserting the pin into the corresponding first jack and second jack, the extension plate can be fixed, so that the length of the immobilization device can be adjusted according to the length of the patient's arm for convenient daily use. In addition, the clamping strip can be pulled out from the card slot, and through the rotation of the rotating shaft, the angle between the two support members can be adjusted, and finally the clamping strip is reinserted into the card slot to fix the angle between the two support members, so that the bending degree of the patient's arm can be adjusted according to the patient's recovery needs.

[0004] However, this device has certain limitations in use. Although each component of the device can indeed be adjusted according to the patient's personal situation and needs during use, the adjustment of the device basically requires disassembling a certain component and reassembling it to meet the adjustment function. Therefore, it is not simple enough in actual use, and each adjustment requires reinstallation and wearing; secondly, this device can only provide a fixed function for the patient's hand and does not have a suitable support method, which may cause the patient to feel fatigued or limit the patient's movement during use.

[0005] Therefore, there is a need for a device for elbow joint immobilization after brachial artery puncture. This device fixes the upper arm and forearm of the patient and is equipped with a locking mechanism, which can lock the angle according to the bending requirement of the patient's elbow; in addition, the device can be slidably adjusted according to the length of the patient's arm, and when the user wears this device, the rotation of the wrist will not be affected, ensuring a certain degree of flexibility of the patient's arm after wearing the device; secondly, the device has the function of compressing and stopping bleeding, which is convenient for timely hemostasis when removing the puncture tube after puncture, preventing bleeding and bruising; at the same time, the device can also provide a certain degree of protection and support for the patient's elbow joint; finally, the device is equipped with a sling for hanging the patient's arm on the neck to reduce the burden on the elbow joint caused by the weight of the arm.
