Abstract
The invention belongs to the field of medical instruments and relates to an arterial blood gas needle with medicine disposed in a needle seat. The arterial blood gas needle comprises a needle cylinder and the needle seat integrally connected with the needle cylinder, and a piston is arranged in the needle cylinder. The arterial blood gas needle is characterized in that solid anticoagulant is arranged in the needle seat and provided with a through hole. A short tube extends from the front end of the needle seat into the inner cavity of the needle seat, at least one gap is formed in the short tube, a columnar ring space is formed between the short tube and the inner wall of the needle seat, the solid anticoagulant is arranged in the columnar ring space, the inner diameter of the short tube is equal to that of the through hole, a closing mouth is formed on the outer-side end portion of the needle seat, and the front end of the solid anticoagulant is limited and fixed by the closing mouth. By the arterial blood gas needle, effective emptying of air in the needle cylinder can be realized, no blood pollution during blood sampling can be guaranteed, and blood anticoagulation can be effectively realized.
Description
Technical field
The invention belongs to medical instruments field, relate to the arterial blood air tube of the built-in medicine of a kind of needle stand.
Background technology
Arterial blood gas analysis is regulated the various parameters of mechanical ventilation and is corrected soda acid and electrolyte imbalance etc. the clinical guidance oxygen therapy and has very important significance.The 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, to enter the time that touches anticoagulant behind the syringe more early better for arterial blood; 2, should make arterial blood and air isolated.
The position that syringe with syringe needle can be retained air has three, is respectively in the syringe; In the needle stand; In the syringe needle.When piston is shifted the syringe bottom onto, can retain the position of air and just only be left two, namely in the needle stand and in the syringe needle.The space is small in the syringe needle, and the air of retention is trace extremely; And the space is large in the needle stand, and the volume of retaining air can surpass more than 30 cubic millimeters and (calculates by the standard syringe needle stand), and this only is that the vim and vigour of the arterial blood of 0.5-1.0ml form impact greatly for the blood drawing amount.
The arterial blood air tube that uses clinically at present, be external import, its anticoagulant is placed in the syringe with spherical or lamellar, thereby caused also will retaining the part air in the syringe, therefore, the performance of product has a long way to go compared to the specification requirement of arterial blood air tube at present, can not satisfy clinical accurate requirement to blood gas analysis.
Summary of the invention
The present invention is directed to the problems referred to above, the arterial blood air tube of the built-in medicine of a kind of needle stand is provided, adopt this arterial blood air tube can realize the air in the syringe effectively emptying, guarantee that blood is not contaminated in blood collection procedure, effectively realize the purpose of blood anticoagulant.
According to technical scheme of the present invention: the arterial blood air tube of the built-in medicine of a kind of needle stand, comprise syringe and the needle stand that is connected with the syringe one, have piston in the syringe, it is characterized in that: be provided with solid-state anticoagulant in the described needle stand, described solid-state anticoagulant has through hole.
As a further improvement on the present invention, described needle stand front end extends in the needle stand inner chamber and is provided with short tube, and is provided with at least one slit at this short tube, formation column torus space between short tube and needle stand inwall.
As a further improvement on the present invention, be provided with solid-state anticoagulant in the described column torus space.
As a further improvement on the present invention, the internal diameter of described short tube equates with the through hole internal diameter.
As a further improvement on the present invention, 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 a further improvement on the present invention, described solid-state anticoagulant is heparin sodium.
Technique effect of the present invention is: can get rid of on the one hand the air in the needle stand, arterial blood is contacted 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 invention is further described.
In Fig. 1 ~ 7, comprise syringe 1, piston 2, needle stand 3, solid-state anticoagulant 4, through hole 5, closing in 6, short tube 7, slit 8 etc.
As shown in Figure 1 and Figure 2, the present invention 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 that is connected with syringe 1 one, has piston 2 in the syringe 1, be provided with solid-state anticoagulant 4 in the described needle stand 3, described solid-state anticoagulant 4 has through hole 5, in concrete the application, the diameter of through hole 5 generally equates with the pin hole internal diameter of arterial blood air tube syringe needle, can take a blood sample smoothly in order to guarantee, 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, is specifically determined by process conditions.
To be provided with in needle stand 3 anterior end to close up 6 such as Fig. 3 ~ Fig. 4 the first embodiment of the present invention, 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 has guaranteed that by 6 spacing the fixing of closing up solid-state anticoagulant 4 can landing from needle stand 3.
Shown in Fig. 5 ~ 7, the second embodiment of the present invention is to be provided with one section short tube 7 in needle stand 3, solid-state anticoagulant 4 is positioned between short tube 7 outer walls and needle stand 3 inwalls, specific implementation is as follows: be extended with short tube 7 from needle stand 3 front ends in needle stand 3 inner chambers, and be provided with at least one slit 8 at this short tube 7, be provided with solid-state anticoagulant 4 in the column torus space that forms between short tube 7 and needle stand 3 inwalls, the internal diameter of short tube 7 equates with through hole 5 internal diameters, namely, solid-state anticoagulant 4 is set on the short tube 7, when blood sampling, arterial blood is drawn in the syringe 1 by the internal diameter of short tube 7, interior when mobile at short tube 7 when arterial blood, arterial blood contacts with solid-state anticoagulant 4 in the slit 8 of the very first time by short tube 7, realizes the purpose of effective anticoagulant.
Solid-state anticoagulant 4 among the present invention is heparin sodium.
Work process of the present invention is as follows: when the preparation for acquiring arterial blood, piston is placed the bottom of syringe, the patient is treated that blood sampling place carries out the sterilization of conventional local skin, to be needled into target arterial with the arterial blood gas of syringe needle subsequently, the pulling piston, make in the arterial blood suction syringe, in this process, blood at first contacts with anticoagulant at the needle stand position, anticoagulant dissolves in the interior whole arterial bloods of pipe subsequently, reach anticoagulation, extract syringe needle after, need immediately syringe needle to be inserted in the block rubber, with secluding air and prevent the pricking wound patient or other medical workers, and then unload syringe needle, and seal the needle stand mouth with rubber sleeve immediately, with the arterial blood censorship that collects.
