Gravity pressure combined with low blood transfusion machine device

Abstract

A low-position blood transfusion machine device for both gravity and pressure, including a blood transfusion set, which includes a puncturer, a compression tube, a drip funnel and a needle connected sequentially through a blood transfusion catheter, and an elastic opening is provided at the inlet and outlet of the compression tube body; The elastic opening part is connected by a large cylinder and a small cylinder. The outer peripheral wall of the large cylinder is tightly connected with the inner wall of the compression tube, and there is a gap for blood flow between the outer peripheral wall of the small cylinder and the inner wall of the compression tube; The blood injection hole, the open end of the blood injection hole is located on the outer end surface of the large cylinder, the closed end of the blood injection hole is located in the small cylinder body, and the small cylinder body is provided with an opening for laterally communicating the blood injection hole with the peripheral wall of the small cylinder. The present invention can carry out normal blood transfusion work under the conditions of high position, flat position and low position without causing damage or damage to the blood transfusion body, thus realizing safe, efficient, fast and convenient blood transfusion work under various conditions and occasions.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a low-position blood transfusion machine device with both gravity and pressure functions, which is suitable for transfusing blood to patients. Background technique [0002] As we all know, the routine way to transfuse blood to patients in medical treatment is to hang the blood transfusion bag high, and use the gravitational potential energy of the liquid in the blood transfusion bag to inject the liquid into the patient's vein. The first premise of this method is that the conditions for hanging the blood transfusion bag must be met, otherwise the blood transfusion cannot be performed. However, in some cases, when the blood transfusion for the patient does not meet the high hanging conditions, only moderate pressure can be used for blood transfusion, and the squeezing force cannot directly act on the blood transfusion bag, otherwise it may cause damage and influence on the blood liq...

Problems solved by technology

However, in some cases, when the blood transfusion for the patient does not meet the high hanging conditions, only moderate pressure can be used for blood transfusion, and the squeezing force cannot directly act on the blood transfusion bag, otherwise it may cause damage and influence on the blood liquid, so now Some blood transfusion methods have great limitations
