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

A low-level transfusion machine device used through gravity and pressure comprises a transfusion device. The transfusion device comprises a puncture device, a compression tube, a drip chamber and a syringe needle which are connected in sequence through a transfusion catheter. The inlet and the outlet in a compression tube body are respectively provided with an elastic opening piece. Each elastic opening piece is formed by connecting a large column body and a small column body, wherein the outer circumferential wall of the large column body is in sealing fit connection with the inner wall of the compression tube body, and a gap for blood to flow is reserved between the outer circumferential wall of the small column body and the inner wall of the compression tube body. Each elastic opening piece body is internally provided with a blood injection hole channel, wherein the open end of the blood injection hole channel is located in the outer end face of the large column body, the closed end of the blood injection hole channel is located in the corresponding small column body, and the small column body is internally provided with an opening slot through which the blood injection hole channel can be laterally communicated with the outer circumferential wall of the small column body. The low-level transfusion machine device can carry out normal transfusion operation under the high-level, the horizontal-level and the low-level conditions, the transfusion liquid cannot be damaged, and therefore the low-order transfusion machine device can carry out safe, efficient, fast and convenient transfusion operation on various occasions under various conditions.
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 li...
