The advantages of vacuum blood collection tube and bidirectional blood collection needle
The advantages of vacuum blood collection tube and two-way blood collection needle Wu Qiuhong (Hainan Outpatient Clinic, Hainan Provincial People's Hospital, Haikou, Hainan 570102) Currently. Our hospital used vacuum standard test tubes and two-way blood collection needles to replace the glass tubes and disposable syringes that were customarily used in early clinical practice. Early clinical practice was to use disposable syringes to inject blood into each test tube, such as adding anticoagulants to the tube. Must be mixed and then sent to the inspection. However, when there is insufficient or excessive blood collection, the use of anticoagulants is not correct, or clotting occurs due to insufficient anticoagulants. This not only delays detection, but also results in test errors, as well as pollution caused by open tubes. One of the reasons is to bring unnecessary misleading losses to clinicians and patients. Compared to the old-fashioned blood collection method, the advantages of vacuum blood collection tubes are: Since it is a vacuum blood sampling device, the air has been drawn in the test tube according to the required blood volume, so blood is collected. The amount is very accurate. The anticoagulant in the anticoagulant tube matches the blood volume of the anticoagulant, and will not be caused by excessive blood collection (on page 98). Through early sucking of the nerve endings of the papillary nerve to transmit the anterior pituitary, releasing prolactin, prompting the breast to secrete milk early, ensuring breastfeeding = Some breastfeeding research scholars have found through extensive scientific research and observation that early postpartum lactation and increased feeding Milk frequency can promote milk secretion, increase milk production and extend breastfeeding time%. From the data we can see: maternal-infant siblings, early suction phlegm and sucking group maternal postpartum 4-6 months of pure breastfeeding rate was significantly higher than the control group ( P 3.2 Effect of maternal and infant communion, early sucking and sucking on maternal and infants reduces the prevalence of infants = the newborn's immune function is very weak and susceptible to pathogenic microorganisms, breast milk contains infantile clots: vacuum blood collection tube Corks with different colors, different colors for different purposes, such as yellow for biochemical serum tubes, purple head for blood, light blue cap tube for the determination of clotting time, black for the blood sedimentation test, etc. And with a tick mark as a marker, it is easy to make mistakes at a glance, and avoid the occurrence of inaccurate test results due to the wrong use of a test tube = the diameter of the tube is In addition, different lengths and lengths represent different blood collection volumes = safety caps covered with vacuum blood vessels to effectively prevent medical personnel from contacting blood samples during collection and transportation to prevent nosocomial infections. In addition, blood collection tubes are made of tempered glass or special plastic. Minimal damage rate: The vacuum blood collection tube also ensures that the inner wall of the test tube is clean and sterile. All nutrients, multiple antibodies, immune substances, lysozyme and other factors required within 4-6 months are beneficial to the healthy development of infants and reduce the incidence of infectious diseases. According to the statistics of the World Health Organization, there are approximately 2 million each year. Children died of malnutrition and related diseases such as digestive system respiratory diseases, etc. 1 Wang Yaxi, Wu Shiyi.
