Abstract

The utility model provides a booster which comprises a push rod and a barrel body sleeved on the push rod. The barrel body is formed by integrally screwing an upper barrel and a lower cover through internal threads and outer threads, the external threads are arranged on the edge of the lower portion of the upper barrel, and the internal threads are arranged inside the lower cover. A placing hole is formed in the center of the lower cover. The circle center of the placing hole and the circle center of the cross section of the push rod are on the same straight line. Grooves are respectively arranged in cover sides of two ends of the diameter of the placing hole of the lower cover. As an injector is clamped to the lower portion of the barrel body of the booster, the booster slowly boosts in a rotating mode by means of the push rod with threads on a whole body, and solves the technical problems that an injector in the prior art fails in injection, and is unstable in injection speed and unsafe due to strenuous injection under some exceptional circumstances.

Description

Booster

Technical field

This utility model design medical instruments field relates in particular to a kind of booster.

Background technology

Syringe is the most a kind of apparatus of normal application in the clinical treatment work, use syringe the medicinal liquid used different parts in the body injected in the various medicinal liquid processes, all be the pulling push rod, extract medicinal liquid, then use the hand propelled push rod, injecting liquid drug to the target position.

Yet, in the larger injection site of some resistances with when needing fast injection to require to reach treatment, and injection is during thick liquid, often require great effort larger with the hand propelled push rod, be not easy injection and do not reach specification requirement, for example, the injection hypertonic glucose is annotated relatively difficulty with hand push, and for skin ambustion, owing to relatively difficulty is injected in necrosis of epidermal area, for this reason, some people adds the rubber band pulling and has an injection to alleviate people's thrust between needle tubing and push rod, but injection speed is unstable like this, nor safety.

The utility model content

This utility model provides a kind of booster, be used for to solve the prior art syringe and in particular cases is not easy to inject, inject unstable, dangerous and causes injecting failed technical problem at some.

For solving the problems of the technologies described above, this utility model adopts following technical scheme:

A kind of booster, comprise push rod, be enclosed within the cylindrical shell on the described push rod, described cylindrical shell is screwed by internal and external threads with the inner lower cover that is provided with female thread with externally threaded top cylinder by lower edge and is integrated, described lower cover center has putting hole, the center of circle of the center of circle of described putting hole and push rod cross section is on same straight line, and lower cover is respectively arranged with groove on the lid limit at its putting hole diameter two ends.

Further, the bar handle whole installation of described push rod has screw thread, and the part correspondence that cylindrical shell passes push rod is provided with screw thread.

Further, the end of described push rod is provided with and pushes away handle.

Further, described top cylinder prolongs the elliptical aperture that its barrel direction has strip.

The booster that this utility model provides, by with the bottom of syringe card side at the booster cylindrical shell, then slowly rotate propelling by whole screwed push rod, solved in the prior art syringe some in particular cases cause injecting unsuccessfully because needing the effort injection, unstable, the unsafe technical problem of injection speed.

The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model, technical scheme in this utility model is clearly and completely described, obviously, described embodiment is this utility model part embodiment, rather than whole embodiment.Based on the embodiment in this utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of this utility model protection.

Please consult simultaneously accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, Fig. 1 is this utility model booster overall structure sketch map one, Fig. 2 is this utility model booster overall structure sketch map two, Fig. 3 is this utility model booster top cylinder partial enlarged drawing, and Fig. 4 is this utility model booster lower cover structure sketch map one; Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, booster of the present utility model is comprised of push rod 1 and the cylindrical shell 2 that is enclosed within on the push rod 1.Described cylindrical shell 2 comprises top cylinder 21 and lower cover 22, is provided with external screw thread 211 in the lower edge of described top cylinder 21, and the inside of lower cover 22 is provided with female thread 221, and described external screw thread 211 and female thread 221 coincide mutually, and top cylinder 21 and lower cover 22 are screwed is an overall structure.See also accompanying drawing 5, Fig. 5 is this utility model booster lower cover structure sketch map two, as shown in Figure 5, also be provided with a putting hole 222 at the center of described lower cover 22, this putting hole 222 is used for the cylindrical shell of syringe is inserted in it, firmly even in the process of pushing syringe liquid medicine injection for guaranteeing booster, needle roller not, the center of circle of palpus maintenance putting hole 222 and the center of circle of push rod 1 cross section are on same straight line, on the lid limit 223 of lower cover 22 both sides also correspondence be provided with groove 224, this groove 224 is arranged on the place, diameter two ends that putting hole 222 passes its center of circle, and this groove 224 is used for two ears that card is put injector cartridge.

In the above-described embodiments, integral body is provided with screw thread on the described push rod 1, on this screw thread and the top cylinder 21, the screw thread at the position passed of push rod 1 is corresponding, thereby so that push rod 1 can slowly be pushed into cylindrical shell 2 inside by the mode of rotation, thereby guaranteed the stability of injection speed in injection.

Further, firmly balanced in pushing away the process of sailing for guaranteeing booster, arrange one in the end of described push rod 1 and push away handle 11, when hands by being pressed in when pushing away on the handle 11 because stress surface is even, thereby guaranteed that booster is firmly balanced in pushing away the process of sailing.

Further, be handled easily, the convenient observation prolonged the elliptical aperture 212 that direction that push rod 1 carries out is provided with strip at the barrel of top cylinder 21.

It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment this utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of this utility model.
