Description

A kind of elbow flexible support holding device with constant temperature function

technical field

The utility model relates to the technical field of medical aids, in particular to a flexible support and holding device for an elbow with a constant temperature function.

Background technique

So far, the irreplaceability of blood and the scarcity of blood sources have made clinical blood in short supply. The existing concept and technical path of "preoperative deep apheresis autologous blood storage" patent number: ZL.201310023793.4, has the outstanding ability to develop a large number of patients' autologous blood and ensure blood for elective major surgery and major surgery, as well as effectively maintain and It has obvious advantages such as improving the immunity of patients and shortening the average hospital stay after surgery.

In the clinical application of this technology, the cubital vein puncture of the patient is the first choice, and the patient's position is required to be maintained at the same time. When the patient's arm and the machine are not in the same direction, the consumables pipeline needs to be pulled through the body, and the elbow without a fixed arm device can easily pull the pipeline; sometimes when the patient moves the arm due to tension or unconsciousness, it is very easy to bend the arm and cause the blood vessel to perforate; When the temperature is low, the patient remains in the same position for a long time, and the arm puncture site needs to be kept warm. In view of the above factors, medical staff need to constantly remind patients to keep their arms still during the entire operation process, and once an accident occurs, it will affect the smooth collection of blood. If a new vascular access is re-established, the blood will be in danger of coagulation due to staying in the body for too long, and at the same time, the pipeline consumables will be wasted and an unnecessary economic burden will be added to the patient. In order to solve the above technical problems, the existing practice is to wear a cuff on the arm to restrain the arm when the patient performs puncture. However, the existing restraint cuff has weak binding force, and the arm still has defects such as easy movement. On the other hand, the blood flow is slow due to cold weather or personal vascular reasons, and it is not easy to perform blood collection, and the existing restraints cannot effectively assist in blood collection. Therefore, there is an urgent need to develop a flexible support and holding device for elbows with a constant temperature function to solve the various problems raised in the above background.
