Assist blood collection bag

Abstract

The invention relates to a power-assisted blood collecting bag. The power-assisted blood collecting bag comprises a bag body, a standby tube and a blood collecting tube are mounted on the bag body, and a blood collecting needle is mounted at the end of the blood collecting tube. A power booster is serially connected between the blood collecting tube and the blood collecting needle and comprises a power boosting cavity, a driving barrel is movably arranged on the power boosting cavity, and two ends of the driving barrel penetrate the wall of the power boosting cavity. A power boosting wind wheel is mounted on the outer wall of the driving barrel, a driving rod is mounted on the axis of the driving barrel, and the driving rod and the driving barrel are connected through a one-way bearing. The inner periphery of the one-way bearing is in threaded combination with the driving rod, a limiting plate and a driving plate are fixed to two ends of the driving rod, and a reset pressure spring is arranged between the driving plate and the power boosting cavity. The power-assisted blood collecting bag is novel and unique in structure, and on the premise that blood collecting cleanness is guaranteed, blood collecting speed can be effectively increased to accelerate a medical treatment process, pain time of patients is shortened, and psychological stress of the patients is relieved.

Description

technical field [0001] The invention relates to a medical appliance, especially a blood collection bag. Background technique [0002] Blood bag is a commonly used blood collection device. It is widely used because of its low cost, convenient use, and no cross-contamination of blood. Fist to facilitate the expansion of blood vessels and promote blood flow; because animals are different from humans, animals will not cooperate with medical staff in the blood collection process, so blood collection is slow and takes a long time. At the same time, as animals struggle , the blood collection operation becomes extremely difficult; it also causes pain for a long time to the animals; in addition, for patients with low blood pressure in the body, such as weak women and the elderly, the blood flow rate is slow, and it also takes a lot of time in the blood drawing process Too much time will undoubtedly bring greater resistance to blood collection.

[0002] Blood bag is a commonly used blood collection device, because of its low cost, convenient use, and no cross-contamination of blood, it is widely used; in the process of blood collection, medical staff often require the blood collector to hold and relax Fist to facilitate the expansion of blood vessels and promote blood flow; because animals are different from humans, animals will not cooperate with medical staff in the blood collection process, so blood collection is slow and takes a long time. At the same time, as animals struggle , the blood collection operation becomes extremely difficult; it also causes pain for a long time to the animals; in addition, for patients with low blood pressure in the body, such as women with weak constitution and the elderly, the blood flow rate is slow, and it also takes a lot of time in the blood drawing process Too much time will undoubtedly bring greater resistance to blood collection
