Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a blood sample collector. Background Art

[0002] Capillaries can be used clinically to collect blood samples for in vitro diagnostic analysis. After the capillary tube collects the blood sample, the blood sample can be sent to a biochemical test reagent disk for testing. The blood sample needs to be discharged from the capillary tube. This process is called sampling. When collecting peripheral blood samples from patients for examination clinically, the fingers are generally disinfected with sterile cotton balls, and then the fingers are pierced with a needle, and then aspirated with a straw. This operation is very troublesome, time-consuming and labor-intensive, which greatly increases the difficulty of the work for medical staff.

[0003] For example, the Chinese utility model patent with application number CN201020629380.2 discloses a "Peripheral Blood Sample Collection Device", which includes a pressurizing cover on the needle body, a spring inside the pressurizing cover, and a pinch ring at the root of the pressurizing cover.

[0004] However, when replacing the blood collection tube, it is necessary to first pull out the existing blood collection tube and then insert a new one, which increases the complexity of the operation. In addition, since the blood collection tube needs to be placed flat on the bed surface, if it is accidentally touched or pulled, it will reduce the stability of the collection needle and cause the collection needle to deviate, which may easily cause accidents.
