Problems solved by technology

[0004] First, the infusion needle and the hose on the traditional blood collection and transfusion set are connected by a straight-through connection with a taper. Therefore, the connection reliability is not high, and there is a hidden danger of falling off due to external force
[0005] Second, during the blood collection and transfusion process of the traditional blood collection and transfusion device, since the puncture device connected to the exhaust branch with air filter has no handle position, the labor intensity during the puncture operation is also increased.
[0006] Third, the blood filter in the traditional blood collection and transfusion device is installed in the inner cavity of the dripping funnel, which shares the same internal space with the dripping funnel, and the blood first enters the non-filtered end of the blood filter, and then flows from the filter end. The flowing blood has a certain oppressive effect on the filter, and the blood itself has a certain viscosity. Therefore, it is very unfavorable to observe the blood flow rate in the pipeline system in time.
In the incineration process, the incineration process of polyvinyl chloride materials is relatively difficult, and burial will cause serious pollution to the soil. Hydrogen chloride and dioxin gas will be produced during incineration. Hydrogen chloride will form acid rain, and dioxin gas is a carcinogen.
Therefore, it is not conducive to environmental protection

Abstract

The invention provides a safe blood sampling and transfusion apparatus. The safe blood sampling and transfusion apparatus comprises a blood sampling branch, a blood transfusion branch, a first puncture device (1), a second puncture device (2) and a transfusion needle (17); a drip chamber (10) is connected to the blood transfusion branch, a separating plate (103) is fixedly connected to the interior of an inner cavity of the drip chamber (10), and the inner cavity of the drip chamber (10) is separated by the separating plate (103) into a filtering cavity (102) and a collecting cavity (106) which are mutually independent; a catheter (104) is fixedly installed on the separating plate (103), and the filtering cavity (102) is communicated with the collecting cavity (106) through the catheter (104); and a filtering net (11) is fixedly installed in the filtering cavity (102). By means of the safe blood sampling and transfusion apparatus, the filtering cavity on the drip chamber can be appropriately extruded to force impurities deposited on the filtering net to be separated from the filtering net, and the output flow in the pipe returns to normal; meanwhile, the impurities cannot forcedly penetrate the filtering net to be finally output out of the human body, and the reliability and the safety of blood transfusion are guaranteed.

Description

technical field [0001] The invention relates to a blood collection and transfusion device, in particular to a safe blood collection and transfusion device. Background technique [0002] At present, the blood collection and transfusion device used in the medical industry is provided with an exhaust branch with an air filter. The exhaust branch is a medical connecting hose, and its two ends are respectively connected with the air filter and the puncturer. In the blood collection treatment, when the blood collection and transfusion device is performing the operation of puncturing the infusion bottle, the puncturer should be inserted through the infusion bottle first, and the exhaust branch with the air filter should be fixed upwards, therefore, sometimes the air filter with the air filter Forgot to re-fix the exhaust branch, or fix it badly, resulting in pipeline discount or air filter leakage, which affects the normal infusion, reduces the efficiency of blood collection and tr...
