Abstract
The utility model relates to a disposable device for taking sample of blood, belonging to the medical appliance kind, composed of a sleeve barrel, a plug stick in the sleeve barrel, and a rubber plug covering on the front of a plug stick. The utility model is characterized in that pawls are arranged on the outside surface of a stud of the plug stick or on two sides of the stud of the plug stick, and a lower end cap of the sleeve barrel with female cone holes is arranged on the stud of the plug stick. The utility model has the advantages of no infection and convenient operation.
Description
This utility model belongs to medical mechanical domain.
In hospital during to the diagnosis of patient's the state of an illness, often need be to patient's chemical examination of taking a blood sample.At present the hemostix used of hospital generally all adopts conventional injector, syringe by the stopper rod in sleeve, the sleeve, be enclosed within that the plug of stopper rod front end forms, the section of stopper rod is criss-cross; The problem of this hemostix is: return multiple use, easily produce and infect, do not have unidirectional stop performance between stopper rod and the sleeve, operation is convenient inadequately.
The purpose of this utility model is: provide a kind of difficult generation to infect disposable blood taking device easy to use.
The technical solution of the utility model is: based on existing by the stopper rod in sleeve, the sleeve, be enclosed within the hemostix that the plug of stopper rod front end is formed; Outer surface or two sides at a stud of stopper rod are evenly equipped with ratchet; The sleeve lower endcaps that also has a concave cone hole.
Hemostix of the present utility model because disposable use, has ratchet on the stud of stopper rod, and the infection of not producing, good effect easy to use are arranged.
Fig. 1 is structural representation of the present utility model.Fig. 2 is a partial side view.Fig. 3 is the stopper rod cross sectional plan view.
Drawing explanation and embodiment are described below: 5 is sleeves among the figure; The 2nd, stopper rod, the 6th, be enclosed within the plug (piston) of stopper rod 2 lower ends.The section of stopper rod 2 is criss-cross, and just in the middle part of the stopper rod four studs, this utility model being arranged is to be evenly equipped with ratchet 4 on the outer surface of a stud 3 of stopper rod 2 or two sides.Fig. 1 and Fig. 2 are evenly equipped with ratchet 4 (zigzag) on the outer surface of a stud 3 of stopper rod 2.Fig. 3 is the staggered ratchet 4 that is evenly equipped with on the two sides of a stud 3 of stopper rod 2.On a stud 3 of stopper rod 2, be evenly equipped with ratchet 4, ratchet 4 when drawing stopper rod 4 outside the blood sampling is because plastic deformation may be stuck in the week suitable for reading of sleeve 5 along last, stopper rod 2 can not be withdrawn in the sleeve 5, so the convenient good effect that uses is arranged under negative pressure in the sleeve 5 or external force effect.After having adopted blood, will have on sleeve 5 lower endcaps 1 cover in concave cone hole, and send to chemical examination after labelled or deposit.Keeping for convenience, can there be a shrinkage pool stopper rod 2 upper ends, and sleeve lower endcaps 1 is inserted in the above-mentioned shrinkage pool.
