Using the sliding property between two different special materials, the transfer operation pad forms the effect similar to the drive belt under the external force. The patient is passed over the bed as if on a drive belt, which makes the original time-consuming and labor-consuming bed pass easier. The sliding pad can be used together with disposable medium sheet (bed sheet) to save labor, pass the patient through the bed as a whole and reduce secondary loss. It is especially suitable for patients with fracture, obesity and anesthesia. The vacuum blood collection device consists of three parts: vacuum blood collection vessel, blood collection needle (including straight needle and scalp blood collection needle) and needle holder. The vacuum blood collection vessel is the main component of the vacuum blood collection vessel, which is mainly used for blood collection and preservation. A certain amount of negative pressure is preset in the production process. When the blood collection needle is punctured into the blood vessel, due to the negative pressure effect in the disposable blood collection vessel, the blood automatically flows into the blood collection vessel; At the same time, a variety of additives are preset in the blood collection vessel, which has the advantages of less interference to blood components, no influence on the volume of red blood cells, no hemolysis, fast plasma separation, wide operating temperature range, strong compatibility with serum samples, activation of plasmin and inhibition of thromboplastin, dynamic balance between fibrinogen and fibrin, and prevention of fibrin filament, Most of the indexes in plasma can be detected repeatedly within 6 hours.
Vacuum blood collection is mainly used for the collection and preservation of blood samples. A certain amount of negative pressure is preset in the production process of the vacuum blood collection vessel. When the blood collection needle enters the vessel, due to the negative pressure effect in the blood collection vessel, the blood automatically flows into the blood collection vessel; At the same time, a variety of additives are preset in the blood collection vessel, which can fully meet the clinical multiple comprehensive blood detection. As a rapid and accurate clinical blood collection, vacuum blood collector has the advantages of safety, sealing, convenient transportation, different head color, easy to distinguish, etc., which is a revolutionary innovation of the traditional blood collection method of injector. It is a kind of venous blood collection instrument for blood test in medical clinic, health and epidemic prevention, blood station (bank), blood control and blood disease research and biological products departments.
After more than ten years of application and promotion, the use of vacuum blood collection system has been quite popular, but the industry standard of vacuum blood collection system in China will be formally implemented on August 1, 2008. So far, the product standards of various vacuum blood collection enterprises in China are not the same, so the quality is quite different. According to the composition of the products and the differences between the product technology and the laboratory medicine technology, the products on the market can be roughly divided into five generations.
