A kind of closed ozone filling blood transfusion apparatus and blood transfusion method

Abstract

The invention provides a closed type ozone charging transfusion device and a transfusion method. The transfusion device comprises a check valve (1) and a blood taking bag (4), wherein the check valve (1) comprises a valve body (101), a compression spring (102) installed in an inner cavity of the valve body (101), a valve ball (103) and a bacterial filtering membrane (104), the bacterial filtering membrane (104) is fixedly connected to the inlet end of the valve body (101) and covers an inlet of the inner cavity of the valve body (101), the inlet of the inner cavity of the valve body (101) is sealed by the valve ball (103) through elastic force of the compression spring (102), and the outlet end of the valve body (101) is connected and communicated with a pipeline of the blood taking bag (4).When ozone is charged, firstly, the outlet end of an injector which contains the ozone and is not provided with a needle is in sealing connection with the inlet end of the check valve, and then the ozone passes through the bacterial filtering membrane to be charged into the inner cavity of the blood taking bag through the injector. By utilizing the closed type ozone charging transfusion device, the ozone can be charged in a fully closed environment, hidden pollution danger is effectively avoided, and the closed type ozone charging transfusion device has the obvious advantages of simplicity and convenience in operation, high safety and the like.

Description

technical field [0001] The invention relates to a blood collection and transfusion device for clinical ozone therapy, in particular to a closed ozone filling blood transfusion device and a blood transfusion method. Background technique [0002] At present, the blood collection and transfusion devices used for clinical ozone therapy in hospitals on the market have great potential safety hazards during use, and the operations are complicated. Mainly manifested in the following aspects: [0003] First, due to the many manual connection points, such as blood collection bags containing anticoagulants, saline bags containing normal saline, and puncture injection of ozone, these connection operations are all open operations. The traditional operation will bring a greater risk of contamination to the patient. [0004] The second is that there are many manual steps, and the possibility of the operator being polluted is also greatly increased. [0005] The 3rd, when manually fillin...

AI Technical Summary

Problems solved by technology

[0003] First, due to the many manual connection points, such as blood collection bags containing anticoagulants, saline bags containing normal saline, and puncture injection of ozone, these connection operations are all open operations. The operation will bring a greater risk of contamination to the patient

[0004] The second is that there are many manual steps, and the possibility of operator contamination is also greatly increased.

[0005] The 3rd, when manually filling ozone, owing to adopting the needle head of the syringe with needle of 50ml to directly puncture the diaphragm two-way made of PVC on the blood collection bag, and the aperture of the diaphragm two-way is small, slightly improper operation, extremely It is easy to puncture the hands of the operator; in addition, the mixing between the injected ozone and the blood in the blood collection bag containing anticoagulant is not thorough, which affects the clinical effect of ozone therapy
