Abstract
The utility model relates to a disposable no-residue syringe for injection of various medicines, including piston syringe and syringe needle, characterized by piston syringe's piston tube top nipple is the circular truncated cone shape, and the aseptic position of pintle cooperates with the nipple, and the top of piston rod is the oblate cone body, coincide with needle stalk bottom, and the cooperation of pintle and nipple is that the pintle dress is in the nipple of piston tube, and the nipple is outside promptly, including the pintle, can eliminate the cavity like this, ensures that the dosage is accurate. The utility model has the advantages of it is following: 1. the dosage application is more accurate and safer for the drugs with high potency, small therapeutic index and small safety range and the drugs for newborns and infants; 2. the skin test solution is prepared more accurately; 3. when the injection is used for small-amount injection of expensive medicines, the waste can be reduced; 4. the needle head is separable from the needle cylinder, so that the needle head can be replaced for multiple people to use, and the waste of the original medicine due to repeated preparation is avoided; 5. the kit is used for blood drawing assay, and the result is more accurate; 6. the pintle is firm and not easy to break.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of disposable noresidue syringe that is used for various injections.
Background technology
The disposable sterilized injector of extensive use is made up of syringe and syringe needle clinically at present, during linking, pintle is enclosed within on the nipple (pintle outside, nipple is interior), gets final product pumping liquid, because pintle, the nipple of this kind of syringe are hollow, cover is fashionable mutually, and underfilling causes dead space, and dead space can be detained medicinal liquid, and causing has following inconvenience clinically:
1, push away medicine and cause liquid waste not to the utmost, use the potency height when need, therapeutic index is little, when medicine that safety range is little or neonate, baby's medication, strict to dosage, adopt the way of dilution to improve degree of accuracy clinically, increased workload to medical personnel.
2, anaphylaxis medicine solution for skin test preparation is also very influenced, because dead space causes observed quantity less than the suction amount, causes solution for skin test concentration after the preparation considerably beyond theoretical concentration.
3, result of laboratory test also can be influenced because of the existence of dead space, and during as blood drawing, its dead space air mixes with blood, when doing blood gaseous analysis, just can influence the result, easily causes misjudgment thus, so waste blood, medicinal liquid.
Summary of the invention
This utility model has solved existing syringe and can not all push medicinal liquid in the body, thereby cause the inaccurate and accurate technical problem of preparing solution for skin test concentration of dosage, provide a kind of medicinal liquid that can make all to push in the body, and can make the solution for skin test compound concentration greatly near the disposable noresidue syringe of theoretical concentration.
This utility model is achieved in that disposable noresidue syringe, includes piston type syringe and syringe needle, the piston tube top nipple that it is characterized in that the piston type syringe is a truncated cone shape, the pintle sterile region cooperates with nipple, and the top of piston rod is flat cone, matches with pin stalk bottom.
This utility model pintle is that pintle is contained in the nipple of piston tube with cooperating of nipple, promptly nipple outside, pintle can be eliminated cavity like this interior, thus guarantee dosage accurately.
Pintle of the present utility model is an entity, and the pin stalk is solidificated in wherein, leaves a circle fin in the middle of pintle handgrip part and the pintle sterile region, and width is 1mm, is convenient to distinguish handgrip part and sterile region.
The top of this utility model piston rod is flat cone, and drift angle is the 110-130 degree.During drawing liquid, liquid arrives piston tip by the pin stalk and promptly enters in the empty tube, and the suction amount equals observed quantity; When pushing away liquid, promote piston rod, liquid is pushed into pin stalk bottom end opening place by piston tip, only obstructs outside the needle point by pin, and not remaining liquid is to improve degree of accuracy.
Disposable syringe and syringe of the present utility model through adopting the Jiangxi flood to reach medical apparatus and instruments factory's production compare test, and its comparing result is as shown in the table:
The beneficial effects of the utility model show:
1, for potency height, therapeutic index is little, safety range is little medicine and neonate, baby's medicine, dose application is more accurate, safety.
2, preparing solution for skin test concentration is more accurate, and anaphylaxis medicine skin test false positive rate is reduced.
When 3, being used for expensive medication and injecting in a small amount, can cut the waste.
4, syringe needle and syringe are separable, so the many people of replaceable syringe needle use, avoid preparing repeatedly the former medicine of waste, can reduce workload simultaneously, and are convenient to the dirt processing.
5,5ml specification syringe is used for the blood drawing chemical examination, and is more accurate as results such as vim and vigour, erythrocyte sedimentation rates.
6, the long 27mm of pin stalk in the pintle, thus very firm, be difficult for losing.

The specific embodiment
In conjunction with the accompanying drawings embodiment is further described, present embodiment is to be used for illustrating of the present utility model, rather than this utility model is carried out any restriction.
Disposable noresidue syringe, form by syringe needle and piston type syringe, the piston tube 7 top nipples 5 of piston type syringe are truncated cone shape, pintle sterile region 4 cooperates with nipple 5, the top 6 of piston rod 8 is flat cone, obstruct 2 bottoms with pin and match,, should will protect pin medicated cap 1 cover thereon for keeping the cleaning of pin stalk 2.
Syringe needle of the present utility model is an entity, and total height is 27mm, in have pin stalk to pass through, there is a circle fin in central authorities, width is 1mm.Pintle integral body is divided into upper and lower two parts.Top is handgrip part 3 (genus clear area), and height is 17mm, and positive taper is carved with decorative pattern to increase frictional force, is convenient to get the dress syringe needle; The lower part is sterile region 4 (belongs to aseptic area, can not pollute, can not catch and touch), high 9mm, inverted cone, fin lower port diameter (being that sterile region suitable for reading also equals the suitable for reading of nipple) 5mm, end mouth diameter 4mm.The height of pintle is the summation of handgrip part 3 (high 17mm), fin (high 1mm) and sterile region 4 (high 9mm) three parts.
Nipple 5 of the present utility model is opposite with existing syringe, last bore 5mm, and following bore 4mm, high 9mm conforms to the pintle sterile region.Pintle is an entity, does not have dead space naturally, insert nipple 5 after, be full of whole nipple, nipple does not also have dead space, dead space is obstructed three places by pintle of the prior art, nipple, pin and is changed and surplusly obstruct a place for pin.Certainly, pin stalk 2 can not be made solid, therefore greatly reduces the residual quantity of medicinal liquid.
Piston rod of the present utility model top 6 is the flat cone at 130 degree angles, and its top and pin stalk top match.During drawing liquid, liquid arrives piston tip by the pin stalk and promptly enters in the empty tube, and the suction amount equals observed quantity; When pushing away liquid, promote piston rod, liquid is pushed into pin stalk bottom end opening place by piston tip, only obstructs outside the needle point by pin, and not remaining liquid is to improve degree of accuracy.
It is all identical with existing specification that the length of piston tube 7 of the present utility model, piston rod 8, internal diameter, piston length etc. are not mentioned part.
