Vacuum sterile blood collection and recovery device

Abstract

The invention discloses a vacuum sterile blood collection and recovery device. The device is mainly formed by sequentially connecting a vacuum blood sampling knife, a vacuum valve and a closed rotary distribution connector in series through a flexible hose. A hollow pipe outlet is formed in the lower end of the closed rotary distribution connector and connected with one end of a vacuum pipeline, the other end of the vacuum pipeline is connected with a vacuum pump, a blood container is installed below the vacuum pipeline, and the lowest position of the vacuum pipeline is communicated with the blood container. The vacuum blood sampling knife is inserted into the body of an animal to sample blood, and the blood is directly pumped into the closed rotary distribution connector by the vacuum pump, is gathered by the closed rotary distribution connector, flows into the vacuum pipeline, and falls into the blood container to be collected when flowing through the lowest position of the vacuum pipeline. According to the blood collection device, blood can be successfully and effectively collected, the problems that the blood is prone to coagulation in the blood collection process and the blood is polluted due to blockage in the vacuum suction process are solved, and the collection efficiency and quality are greatly improved.

Description

technical field [0001] The invention relates to a vacuum aseptic blood collection recovery device, in particular to a vacuum aseptic blood collection recovery device for pigs, cattle, sheep and other slaughterhouses. Background technique [0002] Existing slaughterhouses with large-scale production of pigs and cattle, because blood is difficult to recycle, generally can only be discharged into the sewage system after harmless treatment, not only cannot maximize the use of blood resources, but also need to pay a lot of money to process waste blood High sewage charges. In fact, blood is full of treasures, such as pig blood, which is a red viscous liquid, and its plasma content accounts for 55%, and the plasma contains a lot of beneficial substances, of which plasma protein accounts for 6.7%-7.5%, including fibrin Original, albumin and globulin, etc.; inorganic salts accounted for 0.75%, including NaCl, in addition to K + , Ca +2 , Mg +2 etc. Phospholipids, cholesterol and ...

AI Technical Summary

Problems solved by technology

At present, the difficulty of pig blood recovery is that there is no suitable recovery device. Pig blood will solidify quickly in the air and is easily contaminated. Therefore, the pig blood recovery device needs to be completely isolated from the air and ensure that the pig blood recovery is in a completely closed environment. Finish

[0003] At present, there is no pig blood recovery device in China, and the vacuum blood collection knife is used to recover blood in foreign countries, but its key technology has not yet been disclosed

At present, manual use is widely used in China, which is inefficient and pollutes seriously.
