The utility model discloses a kind of vacuum test tube and pull out cap device, comprise the cylindrical shell of upper opening, the madial wall of cylindrical shell is provided with the strap that inside face is arcuate structure, in the cylindrical shell corresponding with strap position, is provided with the ambulatory splint that inside face is arcuate structure; The level depression bar be connected in outside ambulatory splint extends outside the sidewall of cylindrical shell; There is the movable rod in approximate L shape structure at barrel wall top above depression bar by stud connection, the epimere of movable rod extends to forward the opposite side of cylindrical shell, it is anterior is U-shaped fork structure, the bottom of movable rod oliquely downward extends the formation pressing plate that to be connected mutually with depression bar outer end, and the depression bar between cylinder body outer wall and pressing plate is set with pull back spring.The utility model has the advantage of that structure is simple, small and exquisite, easy to operate, flexible, work efficiency is high.Vacuum test tube can be avoided directly to contact with operator's hand when pulling out cap, avoid cross pollution, blood specimen also can not be caused to spill, more safe and reliable.
Description
Technical field
The utility model relates to hospital inspection room accessory appliances, especially relates to a kind of vacuum test tube and pulls out cap device.
Background technology
At present, health service unit, when blood sample collection carries out biochemical investigation, mostly uses Dispoable medical vacuum test tube, before carrying out biochemical investigation, then is pulled up by the seal cap of vacuum test tube and carries out normal inspection.And sealing blood sampling tube cap choose at present complete by hand, checker is pulling out in cap process, on the one hand because invisible spectro remaining negative pressure can cause pulling out cap difficulty, heparin tube also can be caused to break if hand overexerts, not only staff is damaged, but also need Resurvey blood specimen; On the other hand, because both hands are exerted oneself round about when pulling out cap, while sealing blood sampling tube cap is pulled out, owing to there is no the strong point, be easy to cause spilling of blood specimen in heparin tube.Above-mentioned reason all can cause inspector to work inconvenience, and inefficiency, even also there will be the serious consequence that cross-infection etc. jeopardizes inspector.
Summary of the invention
The purpose of this utility model is to provide a kind of vacuum test tube safe and convenient to use to pull out cap device.
For achieving the above object, the utility model can take following technical proposals:
A kind of vacuum test tube described in the utility model pulls out cap device, comprise the cylindrical shell of upper opening, the madial wall of described cylindrical shell is provided with the strap that inside face is arcuate structure, in the cylindrical shell corresponding with described strap position, is provided with the ambulatory splint that inside face is arcuate structure; The level depression bar be connected in outside described ambulatory splint extends outside the sidewall of described cylindrical shell; There is the movable rod in approximate L shape structure at barrel wall top above described depression bar by stud connection, the epimere of described movable rod extends to forward the opposite side of cylindrical shell, it is anterior is U-shaped fork structure, the bottom of described movable rod oliquely downward extends the formation pressing plate that to be connected mutually with described depression bar outer end, and the depression bar between described cylinder body outer wall and pressing plate is set with pull back spring.
Prevent vacuum test tube from being clipped broken for increasing friction force, the inside face of described strap and ambulatory splint is pasted with flexible coarse lining.
For improving the mobile alerting ability of ambulatory splint, the diapire of described cylindrical shell offers guide groove, described ambulatory splint moves forward and backward along described guide groove.
The cylinder lateral wall corresponding with described pull back spring position caves inward formation detent.
Cylinder body bottom near described strap is provided with flexible liner, is touched brokenly bottom when can prevent heparin tube from putting into; The thickness of flexible liner can be set to plurality of specifications, to adapt to the needs of the heparin tube of different volumes and length.
The utility model has the advantage of that structure is simple, small and exquisite, easy to operate, flexible, work efficiency is high.Vacuum test tube can be avoided directly to contact with operator's hand when pulling out cap, avoid cross pollution, blood specimen also can not be caused to spill, more safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of vacuum test tube described in the utility model pulls out cap device, comprise the cylindrical shell 1 of upper opening, the madial wall of cylindrical shell 1 is provided with the strap 2 that inside face is arcuate structure, in the cylindrical shell corresponding with strap 2 position, is provided with the ambulatory splint 3 that inside face is similarly arcuate structure; The level depression bar 4 be connected in outside ambulatory splint 3 extends outside the sidewall of cylindrical shell 1; Barrel wall top above depression bar 4 is connected with the movable rod in approximate L shape structure by hinge 5, the epimere 6.1 of movable rod extends to forward the opposite side of cylindrical shell, it is anterior is U-shaped fork structure (A/F pitched of U-shaped is greater than the external diameter of heparin tube body and is less than the external diameter of body upper end seal cap), the bottom of movable rod oliquely downward extends to be connected mutually with depression bar 4 outer end and forms pressing plate 6.2, in the end of pressing plate 6.2, can slipmat be set, avoids skidding during finger presses; Depression bar 4 between cylinder body outer wall and pressing plate is set with pull back spring 7.For avoiding clamping friction force when excessively causing vacuum test tube to be clipped broken and increase clamping, strap 2 and the inside face of ambulatory splint 3 are pasted with flexible coarse lining 8, as rubber lining; For ambulatory splint during guarantee work moves flexibly, the diapire of cylindrical shell offers guide groove 9, ambulatory splint 3 can move forward and backward along guide groove 9; The cylinder lateral wall corresponding with pull back spring 7 position caves inward formation detent, can shorten the length of depression bar 4, reduces the volume of cylindrical shell, convenient operation more; Cylinder body bottom near strap 2 is provided with flexible liner 10, and when can avoid placing heparin tube, overexertion causes heparin tube to break; The thickness of flexible liner 10 can be set to plurality of specifications, to adapt to the needs of the heparin tube of different volumes and length.
During use, the heparin tube 11 of seal cap to be got is put into cylindrical shell 1 between the U-shaped fork of movable rod epimere 6.1 front portion, A/F due to U-shaped fork is greater than the external diameter of heparin tube body and is less than the external diameter of body upper end seal cap, so seal cap can not fall from U-shaped fork, cylindrical shell 1 is grabbed with hand, finger presses pressing plate 6.2 is inside, by depression bar 4, ambulatory splint 3 is moved forward, pull back spring 7 is compressed, heparin tube 11 clamps by strap 2 and ambulatory splint 3, the U-shaped fork of movable rod epimere 6.1 front portion is upwards exerted oneself simultaneously, unclamp finger, pressing plate 6.2 return, this process can repeat, until seal cap is extracted, then the inspection process that heparin tube can carry out lower step is taken out.
