Embodiment 1

[0020] Such as figure 1 As shown, a disposable vacuum blood collection tube includes a blood collection needle 1, a bottle stopper puncture needle 2, a connecting tube 3 connecting the blood collection needle 1 and a bottle stopper puncture needle 2, a test tube 4, and a rubber stopper tightly plugged in the mouth of the test tube 4 5. The plastic cap 6 set on the outside of the rubber stopper 5 has a circular gap in the middle of the plastic cap 6. There is a cylindrical plastic stopper 7 at the connection between the connecting tube 3 and the cork puncture needle 2. The plastic stopper 7 is provided with a The screw thread 8 and the threaded mouth 9 provided at the connection of the bottle stopper puncture needle 2 are engaged with each other. When this kind of disposable vacuum blood collection tube needs to carry out multiple blood collection, the plastic stopper 7 can be tightened first when changing the blood collection tube, and then the blood collection tube can be repl...

Embodiment 2

[0022] Such as figure 2 Shown, all the other are identical with embodiment 1, and difference is that test tube 4 is provided with a support 10, and the top of support 10 is semicircular plane 11, and semicircular plane 11 diameter is identical with test tube 4 diameters, and semicircular plane 11 It is a 45-degree inclined surface, and the support 10 can be used to fix the test tube 4 during blood collection to ensure that the blood has a certain inclination angle in the test tube 4, which can prevent blood from flowing backward and keep blood collection smooth.

Embodiment 3

[0024] Such as image 3 Shown, all the other are identical with embodiment 1, and difference is, test tube plastic cap 6 tops are provided with plastic cover 12, and plastic cover 12 edges are provided with plastic rotating shaft 13, and plastic cover 12 is connected with plastic cap 6 by rotating shaft 13 rotation, in During blood collection, cover 12 can be unscrewed, and before and after blood collection, cover 12 is screwed on, can prevent that dust enters test tube 4 mouths, even in test tube 4 in carrying and moving process.

Abstract

The invention discloses a disposable vacuum blood collecting tube and relates to the technical field of medical instruments. The disposable vacuum blood collecting tube comprises a blood collecting needle, a bottle stopper puncture needle, a connection tube for connecting the blood collection needle and the bottle stopper puncture needle, a test tube, a rubber stopper and a plastic cap, wherein an opening of the test tube is stuffed up by the rubber stopper, and the rubber stopper is sleeved with the plastic cap. A round gap is formed in the middle of the plastic cap. A cylindrical plastic blocking piece is arranged at the connecting position of the connection tube and the bottle stopper puncture needle. Threads are arranged on the plastic blocking piece and meshed with a threaded mouth formed in the connection position of the plastic blocking piece and the bottle stopper puncture needle. When blood collection needs to be performed repeatedly, the plastic blocking piece can be firstly screwed in the process of replacing the blood collection tube, then the blood collection tube is moved away, in this way, blood of a patient is prevented from flowing out along the blood collection needle, the connection tube and the bottle stopper puncture needle and being contaminated, and psychological effects on the patient can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a disposable vacuum blood collection tube.
