Description

Clinical medicine uses vacuum blood sampling device Technical Field The utility model relates to the technical field of medical equipment, in particular to a vacuum blood sampling device for clinical medicine. Background The principle of the vacuum blood collection tube is that the blood collection tube with the head cover is pre-pumped into different vacuum degrees, and the internal negative pressure is utilized to automatically and quantitatively collect venous blood samples. In a specific operation, one end of the blood taking needle pierces into a vein of a human body, the other end is inserted into a rubber plug of the vacuum blood collection tube. Under the action of negative pressure, venous blood is pumped into the blood collection tube through the blood collection needle, so that the vacuum blood collection operation is realized. In the prior art, the wall of a blood sampling tube is usually labeled with a label, and the label is marked with information such as the type and the code of a product, and most importantly, the label is used for recording the related information of a blood sample and a patient. Although such labels are convenient to use, because they are generally paper and have a relatively smooth surface, if a medical staff takes and stores the blood collection tube, if the hand is provided with sweat stains or the hand is relatively wet, the label may be damaged, so that the label is worn or the writing is blurred, and the medical staff cannot read the data on the label normally, thereby affecting the accuracy of blood test work. Disclosure of utility model In order to overcome the disadvantages of the prior art, the present utility model aims to provide a vacuum blood collection device for clinical medicine. The utility model provides a clinical medicine is with vacuum blood sampling device, including vacuum heparin tube, the sealing plug, sealed lid, the label, the thread bush, the screw thread section of thick bamboo, first sealing washer and scale strip, vacuum heparin tube top opening part is connected with the sealing plug, vacuum heparin tube top threaded connection has sealed lid, sealed top is uncovered, vacuum heparin tube outer wall connection has label and thread bush, the thread bush is higher than the label, vacuum heparin tube outer wall sliding connection has the screw thread section of thick bamboo, top is equipped with the screw thread in the screw thread section of thick bamboo, be connected with first sealing washer on the thread bush, vacuum heparin tube outer wall is carved with the scale strip. As a preferable technical scheme of the utility model, the vacuum blood collection tube and the thread cylinder are made of transparent materials. As a preferable technical scheme of the utility model, the vacuum blood collection tube further comprises a fixing ring and a second sealing ring, wherein the inner diameters of the upper side and the lower side of the threaded tube are smaller than the inner diameter of the middle part of the threaded tube, the outer wall of the vacuum blood collection tube is connected with the fixing ring, the outer diameter of the fixing ring is the same as the inner diameter of the upper side and the lower side of the threaded tube, and the bottom of the fixing ring is connected with the second sealing ring. As a preferable technical scheme of the utility model, the vacuum blood collection tube further comprises a third sealing ring, and the top of the vacuum blood collection tube is connected with the third sealing ring. As a preferable technical scheme of the utility model, the utility model further comprises rubber strips, and the outer wall of the threaded cylinder is connected with at least two rubber strips. As a preferable technical scheme of the utility model, the vacuum blood sampling tube further comprises a limiting ring, the outer wall of the vacuum blood sampling tube is connected with the limiting ring, the limiting ring is lower than the threaded cylinder, and the outer diameter of the limiting ring is larger than the inner diameter of the bottom of the threaded cylinder. The utility model is provided with the thread sleeve and the thread cylinder, the thread cylinder is made of transparent materials, after the identity information of a patient is written on the label, the thread cylinder is in threaded connection with the thread sleeve, the label is completely shielded by the thread cylinder, so that the label is prevented from being damaged by wet hands, the label can be prevented from being worn or the handwriting is prevented from becoming fuzzy, the normal reading of the information on the label and the degree of a scale bar by medical staff can be ensured, and the accuracy of blood assay work is ensured.
