Abstract
The pressure-maintaining syringe is a medical apparatus used for clinical negative pressure puncture, suction and injection. The utility model discloses add between the empty section of thick bamboo of ordinary syringe and piston with the piston fixer that can the fixed piston and can take out or push the spring exerciser of piston automatically or manually, make the syringe can be automatic or manual production and keep suction and inject power. Thereby solving the problem that the puncture success rate is influenced because a patient needs to pull the piston of the syringe to generate and maintain negative pressure and puncture while performing the negative pressure puncture on artery and vein, hydrops, cyst and the like in clinic. And can automatically extract and inject, thereby saving labor and time. The negative pressure syringe is kept as a main part, and other auxiliary parts for puncture are arranged to form the puncture bag, so that the puncture bag is convenient for clinical use, and cross infection is avoided.
Description
This utility model is the medical apparatus and instruments that is used for clinical medicine puncture, drawing liquid, injectable drug.
Existing common injector for medical purpose all need continue the manpower effect when suction and injection, this power can not produce and keep automatically.Do negative pressure when puncture with it, need the piston of patient limit pull syringe to produce and keep negative pressure, limit to do puncture, it is very awkward to cause operation, dual-purpose wholeheartedly, thus influence the success rate of one-time puncture, need the repeated localised puncture could be successful.Suction and injection all need special messenger's ongoing operation, and the expense people is wasted time and energy.
The syringe that keep-ups pressure is exactly that a kind of syringe that can keep and produce pressure automatically or also can manually produce and keep-up pressure automatically simultaneously will be provided.
Accompanying drawing is the operation principle sketch map of syringe of keep-uping pressure.
The accompanying drawings the technical solution of the utility model.The syringe that keep-ups pressure be between the empty tube (1) of ordinary syringe and piston (2), add with a kind of can fixed piston (2) piston holder (3) and can also can manually pull out or push the Billiard apparatus (4) of piston (2) automatically.Constitute maintenance negative pressure syringe respectively and keep the thrust syringe the external broach of piston (2) generation is different with interior thrust according to Billiard apparatus (4).Between empty tube (1) and piston (2), add Billiard apparatus (4) and constitute maintenance negative pressure syringe with external broach.This also available holder (3) is only permitted piston (2) and is pulled out, and mustn't propulsive mode realizes keeping the function of negative pressure syringe.Piston holder (3) and Billiard apparatus (4) can have multiple way of realization.Both can be together or add separately respectively and be used on the ordinary syringe.The pressure of syringe of keep-uping pressure can be to produce automatically, can also be manually to produce.With the syringe that keep-ups pressure is main part, is equipped with puncture auxiliaries such as puncture needle, suction pipe, test tube, glove, hole towel and forms the puncture bag.
This utility model more now is with the advantage of ordinary syringe: make things convenient for the negative pressure puncture, the patient can attentively be punctured smoothly, avoid wholeheartedly dual-purpose, improve the success rate of puncture.Auto-pumping or injection economize that the people is laborsaving to save time.Form the both convenient clinical use of puncture bag with above-mentioned auxiliary, avoid cross infection again.
Clinical during to puncture such as quiet tremulous pulse, hydrops, cyst, keep the negative pressure syringe to connect puncture needle, piston (2) pushes in the empty tube (1) fully, with piston holder (3) fixed piston (2), after pin passes skin, open piston holder (3), external broach or manpower with Billiard apparatus (4) are extracted piston (2) out, promptly produce negative pressure in the empty tube, after negative pressure reaches requirement, reuse piston holder (3) maintains static piston (2), just carries negative pressure in the empty tube.In puncture, when the negative pressure in the empty tube (1) was lower than the external broach of Billiard apparatus (4), piston (3) was just pulled out automatically, produced lastingly and kept negative pressure.At this moment the just available mode the most smoothly of patient is carried out the negative pressure puncture wholeheartedly, thereby it is awkward to have solved operation, and wholeheartedly dual-purpose influences the problem of puncture success rate.When drawing liquid, can utilize to have outer maintenance negative pressure syringe automatic or manual suction of drawing.When injection, can utilize maintenance thrust syringe to inject automatically with interior thrust.Reach the laborsaving timesaving of people from province purpose.To realize that automatic or manual produces negative pressure or normal pressure and can keep this pressure.
Claims (9)
1, a kind of syringe that keep-ups pressure, its principal character are to add with piston holder (3) that can fixed piston (2) between the empty tube (1) of ordinary syringe and piston (2) and can also can manually pull out or push the Billiard apparatus (4) of piston (2) automatically.
2, also be to produce outer draw or the difference of interior thrust constitutes respectively and keeps the negative pressure syringe and keep the thrust syringe according to the feature of the described syringe that keep-ups pressure of claim 1 according to Billiard apparatus (4).
3, the feature according to the described maintenance negative pressure injection of claim 2 also is to add between empty tube (1) and piston (2) with the Billiard apparatus (4) with external broach.
4, the feature according to the described maintenance negative pressure injection of claim 3 also is also available piston (3), is only permitted piston (2) and pulls out, and can not propulsive mode realize.
5, the feature of injecting according to the described maintenance thrust of claim 2 also is to add the Billiard apparatus (4) with thrust in having between empty tube (1) and piston (2).
6, the feature according to described piston holder of claim 1 (3) and Billiard apparatus (4) also has been multiple way of realization.
7, the feature according to the described syringe that keep-ups pressure of claim 1 is that also the generation of pressure can be that automatic generation also can manually produce.
8, be also that according to the feature of claim 1, the described piston holder of claim 5 (3) and Billiard apparatus (4) both can be together or add separately respectively and be used on the ordinary syringe.
9, the feature according to the described syringe that keep-ups pressure of claim 1 claim 2 is that also to keep the negative pressure syringe be main part, is equipped with puncture auxiliaries such as puncture needle, suction pipe, test tube, hole towel, glove and constitutes the puncture bag.
