Abstract
The utility model belongs to the field of medical equipment, and relates to an arterial blood gas needle with medicine arranged in a piston. The arterial blood gas needle comprises a needle barrel and a needle seat integrally connected with the needle barrel. The piston is arranged in the needle barrel, and the upper end of the piston is connected with a pulling rod. The arterial blood gas needle is characterized in that the end face of the bottom of the piston is connected with a hollow sleeve, solid anticoagulants are arranged in an inner cavity of the sleeve, and when the piston is arranged at the bottom of the needle barrel and the sleeve is arranged in an inner hole of the needle seat in a matched mode, air in the needle seat is exhausted completely. By means of the arterial blood gas needle, air in the needle barrel is effectively exhausted, blood can not be polluted in the blood collection process, and the purpose of blood anticoagulation is effectively achieved.
Description
Technical field
This utility model belongs to medical instruments field, relates to the arterial blood air tube of the built-in medicine of a kind of piston.
Background technology
Arterial blood gas analysis regulates the various parameters of mechanical ventilation and corrects soda acid and electrolyte imbalance etc. clinical guidance oxygen therapy and has very important significance.Arterial blood sample acquisition method has very important impact to Results of Blood-gas, when major influence factors has sampling process and later stage censorship whether with air insulated, whether blood coagulation etc.
The specification requirement of arterial blood air tube mainly contains two aspects: 1, arterial blood enters that to touch time of anticoagulant after syringe more early better; 2, should make arterial blood and air isolated.
The position that syringe with syringe needle can be retained air has three, is respectively in syringe; In needle stand; In syringe needle.When piston is shifted syringe bottom onto, can retain the position of air and just only be left two, in needle stand and in syringe needle.In syringe needle, space is small, and the air of retention is trace extremely; And space is large in needle stand, the volume of retaining air can surpass 30 cubic millimeters above (by standard syringe needle stand, calculating), and this is only that the vim and vigour of the arterial blood of 0.5-1.0ml form impact greatly for blood drawing amount.
The arterial blood air tube using clinically at present, be external import, its anticoagulant is placed in syringe with spherical or lamellar, thereby caused also will retaining part air in syringe, therefore, the performance of product, compared to the specification requirement of arterial blood air tube, has a long way to go at present, can not meet the clinical accurate requirement to blood gas analysis.
Summary of the invention
This utility model, for the problems referred to above, provides the arterial blood air tube of the built-in medicine of a kind of piston, adopts this arterial blood air tube can realize the air in syringe effectively emptying, guarantees that blood is not contaminated in blood collection procedure, effectively realizes the object of blood anticoagulant.
According to the technical solution of the utility model: the arterial blood air tube of the built-in medicine of a kind of piston, comprise syringe and the needle stand being connected with syringe one, in syringe, there is piston, piston upper end is connected with pull bar, it is characterized in that: described piston base end face is connected with hollow sleeve, is provided with solid-state anticoagulant in cannula cavity, when piston is placed in syringe bottom, sleeve pipe is matched with in the endoporus of needle stand, by the air emptying in needle stand.
As further improvement of the utility model, on described sleeve pipe outer circumference surface, offer some circular holes.
As further improvement of the utility model, on described sleeve pipe outer circumference surface, offer groove.
As further improvement of the utility model, described solid-state anticoagulant is heparin sodium.
Technique effect of the present utility model is: can get rid of the air in needle stand on the one hand, can make again on the other hand arterial blood contact with anticoagulant the earliest, thereby reach to greatest extent the specification requirement of arterial blood air tube, for the clinical blood gas analysis that accurately carries out provides essential condition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the first embodiment of this utility model middle sleeve.
Fig. 3 is the second embodiment of this utility model middle sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1 ~ 3, comprise syringe 1, piston 2, needle stand 3, solid-state anticoagulant 4, pull bar 5, sleeve pipe 6, circular hole 7, groove 8 etc.
Fig. 1 and Fig. 2 illustrate the first embodiment of the present utility model, this utility model is the arterial blood air tube of the built-in medicine of a kind of piston, comprise syringe 1 and the needle stand 3 being connected with syringe 1 one, in syringe 1, there is piston 2, piston 2 upper ends are connected with pull bar 5, piston 2 bottom end faces are connected with hollow sleeve 6, sleeve pipe 6 can be disposed in to piston 2 one connects, also sleeve pipe 6 can be movably connected on to piston 2 bottoms, when pull bar 5 moves down in process with piston 2, sleeve pipe 6 is along with piston 2 moves down together, until piston 2 moves to syringe 1 bottom, because the external diameter of sleeve pipe 6 is slightly less than the internal diameter of needle stand 3, and the length of sleeve pipe 6 and needle stand 3 is equal in length, now sleeve pipe 6 fills up the endoporus of needle stand 3, by the air emptying in needle stand 3, on sleeve pipe 6 outer circumference surfaces, offer some circular holes 7, in blood collection procedure, the arterial blood very first time being drawn in syringe 1 contacts by the solid-state anticoagulant 4 built-in with sleeve pipe 6 of the circular hole 7 on sleeve pipe 6, reach the object of arterial blood anticoagulant.
Fig. 1 and Fig. 3 illustrate the second embodiment of the present utility model, the difference of this embodiment and the first embodiment is only, on sleeve pipe 6 outer circumference surfaces, offer groove 8, arterial blood just can contact by the better solid-state anticoagulant 4 of DIYU like this, and offer strip slot 8 on sleeve pipe 6 outer circumference surfaces, in manufacture means, be also more easy to realize, technique is also relatively simple.
Solid-state anticoagulant in this utility model is heparin sodium.
Work process of the present utility model is as follows: while preparing to use, piston is placed in the bottom of syringe, routine disinfection local skin, thrust target arterial, pull push rod, make in arterial blood suction syringe, in this process, first blood contact with anticoagulant at needle stand position, anticoagulant dissolves in the whole arterial bloods in pipe subsequently, reach anticoagulation, extract after syringe needle, need immediately syringe needle be inserted in a block rubber, to completely cut off air and to prevent pricking wound, and then unload syringe needle, with rubber sleeve, seal needle stand mouth, censorship immediately.
