Abstract
The utility model relates to an arterial blood sample collector, in particular to a protective arterial blood sample collector, which comprises a syringe, a push rod, a piston and a needle head, wherein the piston is arranged in the syringe, and the push rod is connected with the outer end of the piston; and the needle head is connected with the front end of the syringe through a luer lock. The protective arterial blood sample collector is characterized in that: a hole stone is arranged on the piston, and a protective sleeve is arranged on the needle head; a plug is arranged in the protective sleeve, and the tip end of the needle head is inserted into the plug, so that the needle head is plugged; an addition agent is arranged on the inner wall of the syringe, and the syringe is made of a PET (Poly(ethylene terephthalate) material or a PET doped composite material with excellent air tightness; the hole stone can be a hole plastic, and the plug is an inert gas tightness thixotropic gel or an aerobic fast-curing adhesive; and the addition agent is a heparin salt. Since the needle head plug is pre-arranged in the protective sleeve, the needle head is plugged by the protective sleeve after blood collection so as to protect health care workers and close a channel between a blood sample and the outside, so that the blood sample keeps an original state, and further, the accuracy of clinical examination is ensured.
Description
Technical field
This utility model is a kind of tremulous pulse blood sample harvester, particularly a kind of protection type tremulous pulse blood sample harvester.
Background technology
Arterial blood gas analysis is a kind of indispensable inspection item in the diagnosis of hypoxemia and acid base imbalance, treatment.Carry out arterial blood gas analysis, need blood sample collection, blood sample collection is realized through tremulous pulse blood sample harvester.Existing tremulous pulse blood sample harvester lacks protector, so when operate miss occurring, accidentally injure medical personnel easily, makes medical personnel that infected risk arranged; And the tremulous pulse blood sample harvester that has, blockage problem can occur, thereby influence the collection of blood sample; The tremulous pulse blood sample harvester that has is owing to the problem of additive influences the Clinical detection value.
Summary of the invention
The purpose of this utility model is in order to overcome the defective that existing tremulous pulse blood sample harvester is accidentally injured medical personnel easily and occurred easily stopping up, to invent a kind of protection type tremulous pulse blood sample harvester.
The purpose of this utility model realizes as follows: said protection type tremulous pulse blood sample harvester, comprise syringe, push rod, piston and syringe needle, and piston is located in the syringe; Push rod is connected the outer end of piston; Syringe needle is connected the front end of syringe through luer lock, it is characterized in that: on piston, be provided with Kong Shi, on syringe needle, be provided with protective sleeve; In protective sleeve, be provided with plug, the tip of syringe needle is inserted in and makes syringe needle by shutoff on the plug; On the inwall of syringe, be provided with additive.
Said syringe adopts the splendid PET material of air-tightness or is mixed with the composite making of PET.
Said Kong Shike thinks the hole plastics.
Said plug is inertia air-tightness thixotropic gel or aerobic fast setting adhesive.
Said additive is a heparinate.
The good effect of this utility model is following: the composite that 1, adopts the splendid PET material of air-tightness or be mixed with PET is made syringe, guarantees that the blood sample vim and vigour do not carry out gas exchange with the external world.2, hole stone or inertia hole plastics are embedded in the piston, and dry seasonal epidemic pathogens is smooth logical, meet water (blood) and then seal, and can stop vim and vigour and extraneous gas exchange thus, guarantee that blood sample keeps original state.3, additive adopts balance Lithium acid heparin calcium and/or other heparinates, guarantees the blood sample ionic equilibrium, guarantees tremulous pulse blood sample ion detection accuracy.4, the syringe needle plug is selected inertia air-tightness thixotropic gel or aerobic quick curing adhesive for use, is preset in the protective sleeve, and blood sampling back protective sleeve is with the syringe needle shutoff; Medical personnel have promptly been protected; Seal blood sample and extraneous passage again, made blood sample keep initial condition, guaranteed the accuracy of Clinical Laboratory.
Description of drawings
Fig. 1 is this utility model structure chart
Among the figure: 1 syringe, 2 push rods, 3 pistons
4 syringe needles, 5 luer lock, 6 hole stones
7 protective sleeves, 8 plugs, 9 additives
The specific embodiment
As shown in Figure 1, said protection type tremulous pulse blood sample harvester comprises syringe 1, push rod 2, piston 3 and syringe needle 4; Piston 3 is located in the syringe 1, and push rod 2 is connected the outer end of piston 3, and syringe needle 4 is connected the front end of syringe 1 through luer lock 5; It is characterized in that: on piston 3, be provided with hole stone 6; On syringe needle 4, be provided with protective sleeve 7, in protective sleeve 7, be provided with plug 8, the tip of syringe needle 4 is inserted on the plug 8 and makes syringe needle by shutoff; On the inwall of syringe 1, be provided with additive 9.
Said syringe adopts the splendid PET material of air-tightness or is mixed with the composite making of PET.This material can guarantee that the blood sample vim and vigour do not carry out gas exchange with the external world.
Said Kong Shike thinks the hole plastics.Kong Shi is a kind of material that many micropores are arranged, and micropore is ventilated when drying, and micropore can stop up when running into moisture or blood, and the ability secluding air can be stopped vim and vigour and extraneous gas exchange thus, guarantees that blood sample keeps original state.The function of space plastics is the same with hole stone, in micropore is arranged, water seal is met in dry ventilation.
Said plug 8 is inertia air-tightness thixotropic gel or aerobic fast setting adhesive.It can avoid gas and extraneous gas exchange in the blood after blood sampling, makes blood sample keep initial condition, has guaranteed the accuracy of Clinical Laboratory; When operate miss occurring, can avoid accidentally injuring medical personnel, laugh at except making medical personnel that infected risk arranged.
Said additive 9 is a heparinate.Heparinate is a kind of blood anticoagulant, and it can guarantee the blood sample ionic equilibrium, guarantees tremulous pulse blood sample ion detection accuracy.
