Abstract
The invention provides an uncapping method of a test tube. The uncapping method is used for achieving the two work processes of test tube cap removal and test tube capping. The uncapping method is achieved through a test tube uncapping mechanism. The uncapping method of the test tube is used for solving the clamping problem of a test tube cap, and the test tube cap is clamped under the condition of reducing external force applied to the test tube cap. Meanwhile, in the test tube cap removal process, the functions that the test tube cup rotates while ascending and the test tube is capped with the test tube cap again can be achieved, and the uncapping method can be compatible with test tubes and test tube caps different in height.
Description
Technical field
The present invention relates to a kind of test tube uncapping method, belong to medical instruments field.
Background technology
Medical blood taking pipe is usually vacuum test tube at present, realizes blood sampling function by negative pressure.At Clinical Laboratory instrument pair
During blood sample is analyzed, the general following two mode that uses:
Remove cap test tube the most in advance, use disposable plastic syringe needle to carry out blood sample extraction；
2. use the hard pins such as draw point, run through cap test tube, it is achieved the extraction of blood sample.
In the second solution, this sampling probe need to be used for multiple times, and in order to avoid the cross-contamination between sample, needs to carry
For extra sampling probe wiper mechanism.Therefore, use first kind of way, remove cap test tube the most in advance, use disposable plastic pin
Head carries out blood sample extraction.Owing to blood taking tube is operated by negative pressure, typically at clamping cap test tube, upwards remove the mistake of cap test tube
Cheng Zhong, it is desirable to cap test tube can be made to remove process more smoothly with Spin tubes cap.Meanwhile, in order to avoid sample contamination, in sampling
After pin sampling, need to return test tube cap.
The test tube being correlated with in prior art takes cap device, as patent documentation 1 (CN105197859A) discloses one
Pipe cap automatically turns on retracting device, sees accompanying drawing 4, and this patented technology mainly includes that cap test tube is opened and cap test tube reclaims two parts
Function.Cap test tube open function mainly by (can be along the first line slideway direction) synchronize near or synchronize away from clamp arm
And pull out cap device 53 and longitudinal moving mechanism (the first driving means 52) realization.Synchronize to lean on by (can be along the first line slideway direction)
Near or synchronize away from clamp arm realize the function of mechanical hand, complete test tube clamping and release.Pull out cap device 53 by surface
Annular knurl processes to be increased and cap test tube direct friction power, completes cap test tube open function.Cap test tube reclaims function mainly by (along the
Two line slideways) the transverse shifting frame 51 that moves left and right makes to pull out cap means 50 and moves to unloading cap fork 70, in zigzag tread patterns power (
One driving means 52) with unload under cap fork 70 acts on jointly, make cap test tube fall into cap test tube retracting device 12.
But, there is many deficiencies in above-mentioned prior art, wherein during removing cap test tube (pulling out cap), does not rotate
Action, removing action has some setbacks, and has the outer risk spattered for blood sample.Pull out cap device and use insertion cap test tube center, and
Dependence frictional force is attached, and this position contacts with blood, is not suitable for the workplace that cap test tube need to cover go back to.Meanwhile, need
Want at least three driving means, test tube clamping device, pull out cap device horizontal mobile mechanism and longitudinal moving mechanism.It is only applicable to
The test tube of single height dimension, for the test tube of differing heights without solution.With regard to current functional requirement, need to open at cap test tube
Open, after sampling, cover back cap test tube, such scheme this functional requirement relatively difficult to achieve.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, it is provided that a kind of test tube uncapping method, uses
In the clamping problem of solution cap test tube, in the case of reducing cap test tube applying external force, clamp cap test tube.Meanwhile, it is capable to it is real
During removing cap test tube now, cap test tube rises and rotates and cap test tube covers back the function of test tube again simultaneously, compatible not
With height test tube and cap test tube.
For achieving the above object, the present invention provides following technical scheme:
A kind of test tube uncapping method, is used for realizing cap test tube and removes and return two work process with test tube cap, use test tube
Raise one's hat mechanism realize, described test tube uncapping mechanism includes: pawl, button, cover plate chamber (also referred to as pawl operating member), adapter cavity, linear electric motors,
