Abstract
A one-off test tube type blood sampler is provided. A rubber plunger is plugged into an opening of a plastic test tube. The plunger is connected with a plastic conduit. An end of the plastic conduit is connected with a hard plastic needle handle and a 7# needle. A plastic adjuster is arranged on the conduit. A plastic pintle and a pintle cap are positioned on the plunger. During operation, it is necessary stave the test tube to switch off the adjuster and the pintle cap. The needle enters into a blood vessel to loosen the adjuster. After blood volume needed in the test tube is observed, it needs to unplug the needle, detach the plunger and deliver the test tube containing blood for assaying. The blood sampler discards an injector to extract blood and then fill the blood into test tube, thus reducing blood cell damage, ensuring more accurate assaying and rejecting additional injector and test tube. A puncture needle is connected with the conduit to ensure flexible blood sampling direction and facilitate to observe accurate blood in the test tube.
Description
Affiliated technical field
This utility model avoids also not being equipped with syringe and test tube in addition with this operating process of test tube of reinjecting of syringe suction blood in the blood vessel when collecting blood sample.
Background technology
Usually during collecting blood sample with syringe suction blood in the blood vessel, again with the blood injecting tube, cost height like this, complex operation, the destruction of increase hemocyte makes the result of laboratory test inaccuracy.Though the test tube of production formula hemostix is arranged at present, in vitro do not have negative pressure and form, when in vitro blood was higher than steam vent, blood can overflow.Also have a kind of vacuum shape that when dispatching from the factory, test tube is, be antivacuum shape often and use.The Li Xingyu of Pingdingshan City design is a kind of clamps test tube with clip and makes test tube be the negative pressure shape, troublesome poeration adds that above several hemostix syringe needle directly links to each other with test tube, the blood sampling direction is restricted, the accurate blood volume that flows into test tube is observed in inconvenience, blood sampling finishes, also need cut off the syringe needle part, influence work efficiency, operate also not aseptic.
Summary of the invention
Need when overcoming in the past collecting blood sample with this operating process of test tube of reinjecting of syringe suction blood in the blood vessel, the cost height, also increase the destruction of hemocyte, and the existing hemostix of producing can not form negative pressure, the blood sampling direction is restricted, can not accurately observe the blood volume that flows into test tube, has gathered blood, also need cut off the technical deficiency of syringe needle part, this utility model provides a kind of disposable test tubular type hemostix.
The technical scheme that its technical problem that solves this utility model adopts is: have plastic test tube (general capacity is 5-10ml) rubber piston of opening part plug of containing mark, both tightly connect, and also can unload.Connect the about 0.1cm of a diameter on the rubber piston, be about plastic catheter and the plastics pintle of 10cm.Put a plastics actuator on the plastic catheter, actuator is used for the switch hemostix, and plastic catheter is terminal to be connected with plastics needle handle and No. 7 metal needles, and the plastics pintle is ready for use on in vitro injecting medicinal liquid or in particular cases connecing syringe pump blood.
The beneficial effects of the utility model are: simple in structure, cost is low, easy to use, avoid blood being aspirated the test tube that reinjects with syringe, reduce hematoclasis, make result of laboratory test more accurate, puncture needle links to each other with the conduit of lacking, make the blood sampling direction flexible, the accurate blood volume of also being convenient to observe injecting tube.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is the vertical section structure figure of embodiment of the present utility model.
1. plastic test tubes among the figure, 2. rubber piston, 3. plastic catheter, 4. plastics pintle, 5. plastics pintle medicated cap, 6. plastics actuator, 7. plastics needle handle, 8. No. 7 metal needles.
The specific embodiment
In Fig. 1, have plastic test tube (1) opening part plug one rubber piston (2) of containing mark.(1) is connected with (2) tightly, also can unload, connect plastic catheter (3) and plastics pintle (4) on the rubber piston (2), put a plastics actuator (6) on the plastic catheter (3), the end of plastic catheter (3) is connected with plastics needle handle (7) and No. 7 syringe needles of metal (8), puts a pintle medicated cap (5) on the plastics pintle (4).During use, flattening plastic test tube (1) closes plastics actuator (6) and builds plastics pintle medicated cap (5), make plastic test tube (1) be negative pressure state, hand thumb and forefinger are held plastics needle handle (7), metal needle (8) thrusts along blood vessel sees blood back, transfer loose plastics actuator (6), plastic test tube (1) is 30 with plastic catheter (3)---60 degree angles, so accurately grasp required blood volume, during to required collection blood volume, extract syringe needle, unload rubber piston (2), send chemical examination the plastic test tube (1) that fills blood.
Claims (1)
1, a kind of plastic test tube mouth top plug one rubber piston that it is characterized in that having containing mark by the first-class disposable blood taking device that constitutes of plastic test tube, rubber piston, plastic catheter, plastics actuator and metal needle, connect the about 0.1cm of a diameter on the piston, the plastic catheter of long 8-10cm.Catheter tip is connected with duroplasts needle handle and No. 7 metal needles, puts a plastics actuator on the conduit.One plastics pintle and pintle medicated cap are arranged on the piston in addition.
