Description

a tourniquet

technical field

The invention relates to the technical field of medical equipment, in particular to a tourniquet.

Background technique

The existing tourniquet is made of natural rubber or special rubber, which is a medical polymer material. It is suitable for medical institutions to use infusion, blood drawing, blood transfusion in routine treatment and rescue, and one-time use for hemostasis;

Generally, a tourniquet needs to be used before the infusion puncture. The time of tying the tourniquet should not be too long. If the tourniquet is too long, it is easy to cause local tissue ischemia and hypoxia, cyanosis of the skin, and inconspicuous blood vessels. After successful puncture, loosen the tourniquet. However, there is a situation where the tourniquet is left on the patient after the puncture. If the tourniquet is not removed in time, it will cause hypoxia and necrosis of the patient's four fingers. It is reported that an elderly man was given intravenous fluids by nurse A after being admitted to the hospital. A put a tourniquet 3 cm above the patient's right elbow. When the venipuncture was fixed for an hour, the patient's sleeve slipped down to cover the tourniquet, so he forgot to remove the tourniquet. Afterwards, A is going to breast-feed his own child, and hand it over to nurse B to continue to complete the doctor's order. B firstly inject the drug solution intravenously, and then connect the infusion tube for rehydration. During the infusion process, the patient repeatedly mentioned "arm pain and the infusion rate is too slow". After 6 hours, after infusion of 500 ml of liquid, nurse C took off the infusion needle and found mild local swelling, which was thought to be caused by extravasation of a small amount of liquid, which was not treated. Nine and a half hours after the venipuncture, the family members found out that the tourniquet was still tied when the patient was applying heat due to local pain, so they immediately removed it and reported it to Nursing Assistant B. After B checked, he instructed to continue applying the heat, but did not report it to the doctor. Four hours after the tourniquet was released, nurse B found two blisters of 2Х2 cm on the volar side of the patient's right forearm, which were mistaken for scalding caused by hot compresses, which were not reported and treated. After another 6 hours, the right forearm was highly swollen, the blisters increased and the back of the hand was purple, and the nurse B reported to the doctor and the dean. The dean organized a consultation and decided to transfer it to a higher-level hospital, because the ambulance could not be contacted for temporary symptomatic treatment. Two days later, the distal 2/3 of the patient's right forearm had turned purple, and he had to be taken to a higher-level hospital by tractor. In order to wait for the family's opinion, the middle and lower 1/3 of the right upper arm was amputated on the third day after the transfer. However, the patient died one week after the operation due to heart and kidney failure caused by the patient's frailty and poisoning infection. It can be seen that if the tourniquet is not taken in time, it will cause very serious consequences, especially for some senile dementia and coma patients. Therefore, it is necessary to develop a tourniquet that reminds the medical staff to remove it in time after the successful infusion puncture.
