Automatic multifunctional venipuncture blood sampling device

Abstract

The invention discloses an automatic multifunctional venipuncture blood sampling device. The automatic multifunctional venipuncture blood sampling device comprises an arm binding seat and a venipuncture assembly. A venipuncture frame and a pulse pressing assembly are arranged on the arm binding seat; the venipuncture assembly comprises a venipuncture seat, and the venipuncture seat is obliquely arranged in the venipuncture frame through a guide rail adjusting assembly; a limiting and disinfecting mechanism is horizontally fixed at the bottom of the venipuncture seat and is used for limiting veins and disinfecting skin during puncture; and a puncture needle is slidably arranged on the venipuncture seat through a guide rail frame. Automatic venipuncture is achieved, manual operation of professionals is not needed, the problems of environment, diseases, human resources and the like of shock puncture blood drawing difficulty patients and cardio-pulmonary resuscitation patients in field first-aid, ambulance transfer or emergency first-aid medical treatment can be solved, rapid and effective puncture is achieved, a life channel can be established as soon as possible, and the patient rescue success rate is improved.

Description

technical field [0001] The invention relates to the technical field of venipuncture and blood collection devices, in particular to an automatic multifunctional venipuncture and blood collection device. Background technique [0002] Veins are blood vessels that collect and return blood to the heart. They are often accompanied by corresponding arteries. They are more numerous than arteries, have a larger diameter, and have a larger blood capacity. About 65-70% of the blood in the systemic circulation is contained in the veins (except the blood stored in the portal system, liver and spleen), and about 50-55% of the blood in the veins in the pulmonary circulation. The wall of the vein is thinner and weaker than that of the artery, and its elasticity is also small. Therefore, in the fixedly stained section, the wall of the vein is often collapsed, and the lumen becomes flat or irregular. Patients with difficulty in puncture due to collapse, those who need parenteral total intrav...

AI Technical Summary

Problems solved by technology

[0004] Currently, the venipuncture devices used in the market are simple in structure and are mostly operated manually. When nurses without professional first aid experience cannot effectively puncture the patient, it is impossible to effectively establish a blood collection and infusion channel to maximize the success of patient rescue. At the same time, there is a lack of auxiliary measures to locate the vein and disinfect the skin during venipuncture, which is not convenient enough to use, and it is prone to infection or deviation during venipuncture
