Embodiment Construction

[0024] A new type of blood transfusion device includes a Murphys tube, a blood transfusion tube, a transfusion tube and an output tube, and the transfusion tube is not cross-connected with the transfusion tube. In this way, the infusion tube will not be contaminated by blood, avoiding the occurrence of agglutination reaction between different blood.

[0025] Such as image 3 The blood transfusion device shown includes a Murphys tube 1, a blood transfusion tube 2, a transfusion tube 3, a flow regulator 4, an output tube 5 and a transfusion needle 6. The blood transfusion tube and the transfusion tube are respectively connected to the upper tube wall of the Murphys tube, and the blood transfusion tube and the transfusion tube are not cross-connected. The upper wall of the Murphys tube is composed of a low connection 12 and a high connection 13, and there is a height difference H between the low connection and the high connection, that is, the high connection is higher than the low ...

Abstract

The invention provides a novel blood transfusion device which comprises a Murphy's tube, a blood transfusion tube, a liquid transfusion tube, a flow adjuster, an output tube and a liquid transfusion needle. The blood transfusion tube and the liquid transfusion tube are connected on the upper tube wall of the Morpheus tube respectively, and the blood transfusion tube and the liquid transfusion tube are not connected in a crossed manner. The blood transfusion device can avoid agglutination reaction in the process of blood transfusion, can effectively prevent air from entering a blood circulating system of a human body and can maintain lasting and good filtering effect. Due to a convenient and quick operation mode of the blood transfusion device, medical staff can be liberated from troublesome blood transfusion work. Consequently, the blood transfusion device has high application value clinically.

Description

Technical field [0001] The invention relates to a medical device, in particular to a disposable blood transfusion device. Background technique [0002] In the clinical work of hospitals, patients often need blood transfusion, and more than one bag of blood is transfused. In the process of blood transfusion, the two bags of blood need to be separated with normal saline. This is to prevent the blood clotting reaction of the two bags of blood with different blood sources. Such as figure 1 As shown in the existing single-tube blood transfusion device, there is only one puncture needle at the top of the infusion tube, and the puncture device needs to be pulled back and forth to connect to the saline bag or blood bag respectively. This is not only very cumbersome to operate, but also cannot avoid residual blood. Entering normal saline may cause a blood clotting reaction. Such as figure 2 The Y-shaped blood transfusion device shown, although there are two puncture needles respectivel...
