Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an infection and needle-stick-proof vacuum blood sampling device. Background Art

[0002] In major hospitals, vacuum blood sampling devices are often needed to collect blood from patients for testing. The corresponding vacuum blood sampling devices generally include a vacuum tube for collecting blood and a blood sampling needle component for collecting blood.

[0003] An infection-proof and needle-stick-proof vacuum blood sampling device is disclosed in the Chinese utility model patent application disclosure specification CN216702543U. The infection-proof and needle-stick-proof vacuum blood sampling device includes a puncture needle, a connecting tube connected to the puncture needle through a connecting tube, and a vacuum tube movably arranged in the connecting tube. When in use, first, after completing the disinfection work, the medical staff inserts the puncture needle into the patient's blood vessel. Then, the two sets of trigger mechanisms move at the same time to release the constraint on the elastic potential energy stored in the ejection mechanism, so that the ejection mechanism releases the elastic potential energy and drives the vacuum tube to move linearly toward the insertion needle, so that the insertion needle is inserted into the vacuum tube. Then, the blood enters the vacuum tube through the puncture needle, the connecting tube and the insertion tube. Finally, the puncture needle is pulled out of the patient's body, and the vacuum tube is unscrewed from the connecting tube, thereby realizing the convenient blood collection function of the device.

[0004] However, the device lacks the function of pipe sealing. In actual use, when collecting blood, the device will move the connecting tube and the vacuum tube. At this time, the device cannot ensure the sealing effect in the pipe, which may cause infection. Not only that, the device also lacks a stabilization function. In actual use, when the device is inserted into the blood vessel of the collector, it only relies on the stability of the medical staff to collect blood, so that the medical staff works for a long time, which leads to instability in the blood collection work. Utility Model Content
