Tourniquet with protection function for infusion

Abstract

The invention relates to a tourniquet with protection function for infusion. The tourniquet comprises a fixing ring, an air bag, an air pump, a fixing mechanism and a pressure relief mechanism. The tourniquet with protection function for infusion is characterized in that the air pump blows air into the air bag to fix the tourniquet on an arm while achieving tight encircling. The pressure relief mechanism prevents the air bag from being over-pressured. The fixing mechanism is used to fix an infusion tube. Compared with existing fixing mechanisms, the fixing mechanism of the present invention isprovided with flexible clamping, thereby avoiding damage of the infusion tube due to rigid clamping. Meanwhile, the fixing mechanism avoiding unintentional unlock by a child during playing through apotent spring and a complex unlocking mode, thereby ensuring safety of infusion. Compared with existing pressure relief mechanisms, the pressure relief mechanism of the present invention has an advantage of heating liquid medicine by discharging hot air, thereby improving comfort of a patient. Meanwhile, enough heating time is reserved for the air through intermittent pressure relief, thereby improving heating effect of the liquid medicine, and improving practicability.

Description

technical field [0001] The invention relates to a pulse cuff device with protection function for transfusion. Background technique [0002] The pulse control device is a device that nurses use to tighten the blood volume and then show the veins when looking for intravenous infusion or blood collection. [0003] The pressure time of the pulse control device should not be too long or too tight, and the traditional method of using rubber tubes for pulse pressure, medical staff are not prepared to judge the degree of compression when using it, especially for novice nurses, it is easy to cause repeated pressure. When the debugging occurs, the operation is more troublesome. At the same time, during the infusion, the infusion tube may be pulled, causing the needle to fall off and causing injury to the patient. However, the existing pulse pressure device has a single function and generally only has the pulse pressure function. The protection function of the infusion personnel is un...
