At present, the company is the vice president unit of China Medical Device Industry Association and the vice president of medical polymer products branch. As the backbone production enterprise of medical device industry, Guangxi disposable consumables survive by quality, promote by science and technology, seek development by reputation and create brand by service are the unchangeable ideas of Xinhua medical. Through the unremitting efforts of enterprises and the support of users,
Disposable consumables products in two different aspects, femoral vein puncture blood. In the premise of mining, the same blood, blood required accounting time. The success or failure of each puncture was evaluated and recorded. Blood collection is one of the common methods to collect blood samples in clinical departments. It is mainly used for the collection of blood samples of critically ill patients, obese, infants and other patients with unclear peripheral venous exposure. Obstetrics and Gynecology often have massive hemorrhage. It is difficult for critically ill patients to collect blood from peripheral vein, which requires a large amount of blood samples.
Disposable negative pressure blood collection container is used for serum biochemical test, immune detection, drug detection, etc. The coagulation time of blood can be greatly shortened by evenly coating coagulant on the tube wall. The imported separation glue is not easy to absorb the protein in serum and has strong stability. After centrifugation, the separation glue solidifies to form a barrier, which can completely separate the serum and blood cells, effectively prevent the material exchange between the two, obtain high-quality serum, make the blood test results more real and improve the collection rate of serum. And it can prolong the shelf life. It can be directly operated without blocking the probe channel.
The principle of using chemical disinfectant for disposable vacuum venous blood sample collection container is as follows:
(1) Appropriate disinfectants should be selected according to the properties of the articles and the characteristics of different microorganisms.
(2) Before immersion disinfection, the articles should be cleaned and dried to remove oil and blood pus; When soaking, open the coupling or cover of the instrument and fill it with liquid to make all the articles immersed in the disinfectant. When adding items, you need to time again.
(3) Strictly control the effective concentration, disinfection time and use method of disinfectant, and use fresh disinfectant.
(4) The concentration, time and temperature of disinfectant should be regularly monitored and recorded according to the type and characteristics of disinfectant. The results should meet the requirements of the disinfectant. The disinfectant should be replaced regularly, and the volatile disinfectant should be covered to keep the effective concentration.
(5) Gauze, cotton, etc. can not be placed in the disinfectant, because such items can absorb disinfectants, thus reducing the disinfection effect.
(6) After disinfection, the articles should be monitored regularly, and the monitoring methods and results meet the national standards.
(7) The articles soaked and disinfected shall be rinsed with sterile normal saline or sterile distilled water before use; After gas disinfection, the articles should be used after gas distribution, so as not to stimulate the tissue.
The disposable venous blood sample collection container is composed of test tube, plug, safety helmet, additive and / or appendage, which is divided into sterile supply and non sterile supply. The test tube was vacuumized quantitatively, sealed by butyl rubber plug and equipped with safety helmet to prevent blood splashing when the cover was opened. According to the blood volume and experimental requirements, additives and / or additives that can meet the requirements are preset in the tube, which are distinguished by the color of the safety helmet.
Operation steps:
1. According to the test purpose, select the appropriate type of acquisition tube;
2. Install the double head blood sampling needle on the bracket (refer to the "operation manual of double head blood sampling needle") to ensure the stable connection between the double head blood sampling needle and the bracket;
3. Place the arm of the sampled person downward, select the puncture position, apply tourniquet, and disinfect the puncture position with appropriate disinfection method;
4. Screw down the sheath of the blood sampling needle, and carry out venipuncture under the condition that the arm is downward and one end of the safety cap of the collecting tube is upward;
5. Push the collecting tube into the bracket to make the other end of the blood collecting needle penetrate the diaphragm of the rubber plug. When puncturing the rubber plug, the collection tube should be located in the middle of the stent hole to prevent side penetration and premature loss of negative pressure.
