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 regulates the various parameter of mechanical ventilation to clinical guidance oxygen therapy and corrects soda acid and electrolyte imbalance etc. 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 a later stage censorship whether with air insulated, whether blood coagulation etc.
The technical requirement of arterial blood air tube mainly contains two aspects: 1, arterial blood time of touching anticoagulant after entering syringe is more early better; 2, arterial blood and air exclusion should be made.
Syringe with syringe needle the position of trapped air can have three, is in syringe respectively; In needle stand; In syringe needle.When piston is shifted onto bottom syringe, can just only remaining two, the position of trapped air, namely in needle stand and in syringe needle.In syringe needle, space is small, and the air of retention is extremely micro-; And space is large in needle stand, the volume of trapped air (can calculate by standard syringe needle stand) more than more than 30 cubic millimeters, and this is only the vim and vigour composition impact of the arterial blood of 0.5-1.0ml greatly for blood drawing amount.
The arterial blood air tube used clinically at present, be external import, its anticoagulant is placed in syringe with spherical or lamellar, thus result in syringe and also want remaining portions air, therefore, the performance of current product, compared to the technical requirement of arterial blood air tube, has a long way to go, and can not meet the 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 syringe effectively emptying, ensure that blood is not contaminated in blood collection procedure, effectively realizes the object 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, the needle stand comprising syringe and be connected with syringe one, have piston in syringe, it is characterized in that: be provided with solid-state anticoagulation agent in described needle stand, described solid-state anticoagulation agent has through hole.
As a further improvement on the present invention, described needle stand front end extends and is provided with short tube in needle stand inner chamber, and is provided with at least one gap on this short tube, forms column torus space between short tube and needle stand inwall.
As a further improvement on the present invention, solid-state anticoagulation agent is provided with in described column torus space.
As a further improvement on the present invention, the internal diameter of described short tube is equal with 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 anticoagulation agent is spacing fixing by closing up.
As a further improvement on the present invention, described solid-state anticoagulation agent is heparin sodium.
Technique effect of the present invention is: can get rid of the air in needle stand on the one hand, arterial blood can be made again to contact with anticoagulant the earliest on the other hand, thus reach the technical requirement of arterial blood air tube to greatest extent, for the clinical blood gas analysis that accurately carries out provides essential condition.

Detailed description of the invention
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 anticoagulation agent 4, through hole 5, closing in 6, short tube 7, gap 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, the needle stand 3 comprising syringe 1 and be connected with syringe 1 one, there is in syringe 1 piston 2, solid-state anticoagulation agent 4 is provided with in described needle stand 3, described solid-state anticoagulation agent 4 has through hole 5, in a particular application, the diameter of through hole 5 is general equal with the pin hole internal diameter of arterial blood air tube syringe needle, to ensure to 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, is specifically determined by process conditions.
The first embodiment as of the present invention in Fig. 3 ~ Fig. 4 is provided with closing in 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 anticoagulation agent 4 is 6 spacing fixing by closing up, and ensure that solid-state anticoagulation agent 4 can not landing from needle stand 3.
As shown in Fig. 5 ~ 7, the second embodiment of the present invention is in needle stand 3, be provided with one section of short tube 7, solid-state anticoagulation agent 4 is positioned between short tube 7 outer wall and needle stand 3 inwall, specific implementation is as follows: in needle stand 3 inner chamber, be extended with short tube 7 from needle stand 3 front end, and at least one gap 8 is provided with on this short tube 7, solid-state anticoagulation agent 4 is provided with in the column torus space formed between short tube 7 and needle stand 3 inwall, the internal diameter of short tube 7 is equal with through hole 5 internal diameter, namely, solid-state anticoagulation agent 4 is set on short tube 7, when taking a blood sample, arterial blood is drawn in syringe 1 by the internal diameter of short tube 7, when arterial blood flows in short tube 7, arterial blood contacts with solid-state anticoagulation agent 4 in the gap 8 of the very first time by short tube 7, realize the object of effective anticoagulant.
Solid-state anticoagulation agent 4 in the present invention is heparin sodium.
Work process of the present invention is as follows: when preparation for acquiring arterial blood, piston is placed in the bottom of syringe, patient is treated that conventional local skin sterilization is carried out in blood sampling place, subsequently the arterial blood gas with syringe needle is needled into target arterial, pull piston, make in arterial blood suction syringe, in the process, first blood contact with anticoagulant at needle stand position, anticoagulant dissolves in the whole arterial bloods in pipe subsequently, reach anticoagulation, after extracting syringe needle, need immediately syringe needle be inserted in a block rubber, pricking wound patient or other medical workers is prevented with isolated air, and then unload syringe needle, and seal needle stand mouth with rubber sleeve immediately, by the arterial blood censorship collected.
