Utility model content
The purpose of this utility model is to provide a kind of aseptic vacuum test tube, is intended to solve when being separated from the vacuum tube mouth of pipe by rubber stopper, and the blood sample in vacuum tube may spill, and operator is caused to the problem of infection.This utility model is achieved in that a kind of vacuum test tube, and described vacuum test tube comprises pipe cap and vacuum tube,
Described pipe cap comprises body construction, external screw thread, choking portion, through hole and link; External screw thread is opened in the wall contacts place of body construction and vacuum tube; Through hole is opened in the middle part of body construction; Near through hole, arrange link at body construction lower surface, choking portion is Elastic Cylindrical rubber; Choking portion is connected with the lower surface of body construction by link; Distance between choking portion and body construction is less than externally threaded length; The radius of choking portion is greater than the internal diameter of vacuum tube;
Vacuum tube is the U-tube of one end open, offers the female thread corresponding with external screw thread at the outer wall of vacuum tube with the interior side contacts place of body construction.
In vacuum test tube described in the utility model, described through hole is rounded.
In vacuum test tube described in the utility model, the length of described external screw thread and described female thread is 8-10mm.
In vacuum test tube described in the utility model, the thickness of described choking portion is 1-2mm.
In vacuum test tube described in the utility model, the distance between choking portion and body construction is 3-4mm.
In vacuum test tube described in the utility model, the large 0.8-1mm of internal diameter of the radius ratio vacuum tube of choking portion
Vacuum test tube of the present utility model, by the threaded engagement of pipe cap and vacuum tube, choking portion is driven to block vacuum tube or open vacuum tube, significantly improve the safety of vacuum test tube, the aseptic vacuum test tube blood sample avoided in vacuum tube spills the infection caused operator, and the safety of blood taking tube improves greatly.

In figure: 1, vacuum test tube; 2, pipe cap; 21 body constructions; 22-choking portion; 23-external screw thread; 24-through hole; 25-link; 3, vacuum tube; 31-outer wall; 32-inwall; 33-female thread.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
In the vacuum test tube 1 shown in Fig. 1, described vacuum test tube 1 comprises pipe cap 2 and vacuum tube 3.
Pipe cap 2 is for blocking vacuum tube 3; Vacuum tube 3 is for the blood of accommodating extraction.
As shown in Figure 2,3, 4, described pipe cap 2 comprises body construction 21, external screw thread 23, choking portion 22, through hole 24 and link 25; External screw thread 23 is opened in outer wall 31 contact position of body construction 21 and vacuum tube 3; Through hole 24 is opened in the middle part of body construction 21; Near through hole 24, arrange link 25 at body construction 21 lower surface, choking portion 22 is Elastic Cylindrical rubber; Choking portion 22 is connected with the lower surface of body construction 21 by link 25.
Distance between choking portion 22 and body construction 21 is less than the length of external screw thread 23.
Like this after tightening pipe cap 2 by external screw thread 23 and female thread 33, choking portion 22 just can block vacuum tube 3, and anti-Hemostatic Oral Liquid flows out.And after external screw thread 23 and female thread 33 depart from, choking portion 22 also can depart from vacuum tube 3, and the process departed from is not easy blood is spilt.
The radius of choking portion 22 is greater than the internal diameter (radius of inwall 32) of vacuum tube 3.
Because choking portion 22 is Elastic Cylindrical rubber, there is elasticity, by the radius of choking portion 22 being arranged the internal diameter being greater than vacuum tube 3, making the better tightness of choking portion.
Vacuum tube 3 is the U-tube of one end open, offers the female thread 33 corresponding with external screw thread 23 at the outer wall 31 of vacuum tube 3 with the interior side contacts place of body construction 21.
The corresponding female thread 33 of external screw thread 23 refer to external screw thread 23 can and female thread 33 between coordinate, and the length of screw thread is equal.
Preferably, as described in Figure 3, in vacuum test tube 1 described in the utility model, described through hole 24 is rounded.
Through hole 24 is set, makes blood collection personnel syringe needle can be goed deep in through hole 24, puncturing choking portion 22 and take a blood sample.
Preferably, in vacuum test tube described in the utility model 1, described external screw thread 23 is 8-10mm with the length of described female thread 33.
In vacuum test tube 1 described in the utility model, the thickness of described choking portion 22 is 1-2mm.
In vacuum test tube 1 described in the utility model, the distance between choking portion 22 and body construction 21 is 3-4mm.
In vacuum test tube 1 described in the utility model, the large 0.8-1mm of internal diameter of the radius ratio vacuum tube 3 of choking portion 22
Vacuum test tube 1 of the present utility model, by the threaded engagement of pipe cap 2 with vacuum tube 3, choking portion 22 is driven to block vacuum tube 3 or open vacuum tube 3, significantly improve the safety of vacuum test tube 1, aseptic vacuum test tube 1 blood sample avoided in vacuum test tube 1 spills the infection caused operator, and the safety of vacuum test tube 1 is improved greatly.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize this utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
