2. Technical scheme

In order to solve the above problems, the present invention adopts the following technical solutions.

The utility model provides a negative pressure vacuum test tube, includes the heparin tube body, the upper portion port of heparin tube body is provided with the rubber buffer that is used for the isolation, the top that the top of heparin tube body is located the rubber buffer still overlaps and is equipped with the cap for pipe, the below cover that lies in the cap for pipe on the heparin tube body is equipped with the anticreep lantern ring.

Further, the anti-falling lantern ring is obliquely sleeved on the blood sampling tube body.

Furthermore, the inclined high point of the anti-falling lantern ring is provided with a fixed block fixedly connected with the bottom edge of the pipe cap.

Further, the vertical slide of having seted up in one side that deviates from mutually with the fixed block on the heparin tube body, the slope low point of the anticreep lantern ring corresponds the slide and still is provided with the slider, the slider slides and sets up the inside at the slide.

Furthermore, the width of the inclined high point of the anti-falling lantern ring is smaller than that of the inclined low point of the anti-falling lantern ring.

3. Advantageous effects

Compared with the prior art, the utility model has the advantages that:

(1) this scheme, the high point setting of the anticreep lantern ring is in the bottom of cap, and the low point slides to inlay and establishes inside heparin tube body, wholly be slope form cover and establish on heparin tube body outer wall, and dynamics when extracting the cap is not easily controlled, and the cap is deviate from the heparin tube body and is produced rocking, and the power that the anticreep lantern ring slope form cushioned the cap and extract forms opposite resistance, avoids the in vitro sample to move and swings outer hourglass, has the effect of better pull-back slow force.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.

Example 1:

referring to fig. 1-2, a negative pressure vacuum blood collection tube comprises a blood collection tube body 1, a rubber plug 2 for isolation is disposed at an upper port of the blood collection tube body 1, a tube cap 3 is further sleeved on the top of the blood collection tube body 1 above the rubber plug 2, and an anti-falling shrink ring 4 is sleeved on the blood collection tube body 1 below the tube cap 3.

Referring to fig. 1-2, the anti-slip ring 4 is obliquely sleeved on the blood collection tube body 1.

Referring to fig. 1-2, the inclined high point of the anti-slip collar 4 is provided with a fixing block 5 fixedly connected with the bottom edge of the pipe cap 3.
