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 needle stand.
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 needle stand, 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 needle stand, comprise syringe and the needle stand being connected with syringe one, in syringe, there is piston, it is characterized in that: in described needle stand, be provided with solid-state anticoagulant, described solid-state anticoagulant has through hole.
As further improvement of the utility model, described needle stand front end is to extending and be provided with short tube in needle stand inner chamber, and on this short tube, is provided with at least one gap, between short tube and needle stand inwall, forms column torus space.
As further improvement of the utility model, in described column torus space, be provided with solid-state anticoagulant.
As further improvement of the utility model, the internal diameter of described short tube equates with through hole internal diameter.
As further improvement of the utility model, the outboard end of described needle stand has closing in, and the front end of solid-state anticoagulant is spacing fixing by closing up.
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.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1 ~ 7, comprise syringe 1, piston 2, needle stand 3, solid-state anticoagulant 4, through hole 5, close up 6, short tube 7, gap 8 etc.
As shown in Figure 1 and Figure 2, this utility model is the arterial blood air tube of the built-in medicine of a kind of needle stand, comprise syringe 1 and the needle stand 3 being connected with syringe 1 one, in syringe 1, there is piston 2, in described needle stand 3, be provided with solid-state anticoagulant 4, described solid-state anticoagulant 4 has through hole 5, in concrete application, the diameter of through hole 5 generally equates with the pin hole internal diameter of arterial blood air tube syringe needle, to guarantee, can take a blood sample smoothly, the pin hole internal diameter of the ratio syringe needle that sometimes also the diameter of through hole 5 can be done is slightly large or slightly little, specifically by process conditions, is determined.
The first embodiment as of the present utility model in Fig. 3 ~ Fig. 4 is to be provided with and to close up 6 in needle stand 3 anterior end, the diameter of 6 parts that close up is greater than the diameter of through hole 5, and the front end of solid-state anticoagulant 4, by 6 spacing the fixing of closing up, has guaranteed that solid-state anticoagulant 4 can landing from needle stand 3.
As shown in Fig. 5 ~ 7, the second embodiment of the present utility model is in needle stand 3, to be provided with one section of short tube 7, solid-state anticoagulant 4 is positioned between short tube 7 outer walls and needle stand 3 inwalls, specific implementation is as follows: from needle stand 3 front ends, in needle stand 3 inner chambers, be extended with short tube 7, and on this short tube 7, be provided with at least one gap 8, in the column torus space forming between short tube 7 and needle stand 3 inwalls, be provided with solid-state anticoagulant 4, the internal diameter of short tube 7 equates with through hole 5 internal diameters, , solid-state anticoagulant 4 is set on short tube 7, when blood sampling, arterial blood is drawn in syringe 1 by the internal diameter of short tube 7, when arterial blood interior when mobile at short tube 7, arterial blood contacts with solid-state anticoagulant 4 in the gap 8 of the very first time by short tube 7, realize the object of effective anticoagulant.
Solid-state anticoagulant 4 in this utility model is heparin sodium.
Work process of the present utility model is as follows: when preparation for acquiring arterial blood, piston is placed in to the bottom of syringe, patient is treated to blood sampling place carries out conventional local skin sterilization, subsequently the arterial blood gas with syringe needle is needled into target arterial, pull piston, 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 patient or other medical workers, and then unload syringe needle, and with rubber sleeve, seal needle stand mouth immediately, by the arterial blood censorship collecting.
