Description

Tourniquet

Technical Field

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

Background

The existing tourniquet is refined by medical high polymer material natural rubber or special rubber, is milk white, is flat in strip shape, is packed in a box in a point-to-point overlapping manner, has strong elasticity and can be continuously drawn. Is suitable for the medical institution to perform the transfusion, blood drawing and blood transfusion in the conventional treatment and rescue, and is disposable when in hemostasis; or emergency hemostasis when limb bleeding and field snake and insect bite bleeding.

Generally, a tourniquet needs to be used before infusion puncture, the tourniquet needs not to be pricked for too long time, local tissue ischemia and hypoxia are easily caused due to the overlong time, skin cyanosis is caused, blood vessels are not obviously moved or the blood vessels are crushed, and the puncture is not favorable for success. After the puncture is successful, the tourniquet is loosened. However, the tourniquet is left on a patient after puncture is finished, the tourniquet is not taken down in time, the four fingers of the patient are subjected to oxygen deficiency necrosis, and the venous transfusion of the old person by a nurse is reported and shown after the old person is admitted. The first pricks the tourniquet at a position 3 cm above the right elbow of the patient, and after the fixed bell head of the venipuncture is finished, the sleeve of the patient slides down to cover the tourniquet, so that the patient forgets to remove the tourniquet. Then the first person wants to feed milk to the child and gives the nurse a second person to continue to complete the medical advice. And B, injecting the liquid medicine into the vein, and connecting the infusion tube for liquid infusion. During the infusion process, patients raise 'arm pain and too slow dropping speed' and the like for many times, and B considers that the pain is caused by the stimulation of veins by tetracycline, and explains that: "the intravenous drip should not be too fast because of the disease condition". After 6 hours, 500 ml of liquid is completely transfused, and the transfusion needle is removed by a nurse, and the local slight swelling is found to be caused by the extravasation of a small amount of liquid and is not treated. After venipuncture for 9 and a half hours, when the patient is subjected to hot compress due to local pain, the family members find that the tourniquet is still tied, and then the tourniquet is immediately released and reports to a caregiver B, and the caregiver B orders to continue hot compress after checking the tourniquet but does not report to a doctor. 4 hours after the tourniquet is loosened, the nursing staff B finds that the left forearm of the patient has two 2-piece 2-centimeter blisters on the palm side, and the patients are mistakenly considered as scald caused by hot compress, and the reports and treatment are not yet carried out. After another 6 hours, the right forearm was highly swollen, blisters increased and the back of the hand was purple, and the caregiver was reported to the doctor and the chief. The hospital organization can transfer to the higher hospital for consultation, and the temporary symptomatic treatment of the ambulance is not connected. Two days later, the patient had purple color at the distal end 2/3 of the right forearm and was transported to the higher hospital by using a tractor. To await the family opinions, amputation of the lower middle 1/3 arm was performed no later than the third day after transfer. However, the patient is old and weak, and suffers from heart and kidney failure caused by toxic infection, and then dies after one week of operation. Therefore, the untimely removal of the tourniquet can cause very serious consequences, and particularly, the tourniquet can not be removed from patients in time to cause unreasonable consequences when a plurality of senile dementia and coma patients are in use. Therefore, there is a need to develop a tourniquet which can remind medical staff to take off the tourniquet in time after successful infusion puncture.
