Abstract
The needle-water-medicine integrated injector comprises needle, needle tube, and push tube including front and back ones. Said front push tube having a front film-covered hole is inserted between internal and external tubes of back one which has an axial front tip to break off the film of front push tube. The medicinal powder and injection water are contained respectively in needle tube and front push tube.
Description
The present invention relates to a kind of have an injection syringe of usefulness of patient that is, particularly a kind of medicated powder and solution of collecting is in pipe, and can save inject time and can alleviate medical worker's labor intensity again, and can avoid syringe needle to be exposed to the integral injector with needle and liquid medicine in the external world when extracting solution again with medicated powder.
At present the syringe that generally uses of hospital needs to open the solution bottle earlier by the medical worker before be patient injection, and solution is drawn in the needle tubing, opens powdered medicine bottle again, syringe needle is thrust penetrate solution in the powdered medicine bottle and mix with medicated powder, and then it is interior to patient injection to be drawn into needle tubing.There is such shortcoming in this common syringe: because of syringe needle in extracting solution and medicated powder process repeatedly exposes to the open air in the external world, be vulnerable to pollute, when sometimes syringe needle being thrust the medicated powder bottle stopper, because the effect of the rubber plug cover elasticity tension of bottle stopper, syringe needle can be trapped on the rubber plug cover, syringe needle and needle tubing are separated, can't normally use.
Task of the present invention is the problem that exists at above-mentioned ordinary syringe, provides a kind of medicated powder and solution are loaded in the needle tubing together, with the integral injector with needle and liquid medicine of avoiding syringe needle to pollute.
Integral injector with needle and liquid medicine of the present invention comprises syringe needle, pin battalion and ejector sleeve, it is characterized in that, and ejector sleeve and back ejector sleeve before described ejector sleeve comprises, the external diameter of described preceding ejector sleeve is slightly less than described needle tubing internal diameter, and its front end has a fenestra, and described fenestra is provided with thin film; Described back ejector sleeve is the bimetallic tube of outer tube and interior pipe, and described preceding ejector sleeve inserts between the interior pipe and outer tube of described back ejector sleeve, and is sealed and matched; Described pusher inner axial tube extend a front end have tip, can point broken described before the push rod of ejector sleeve upper film; Injecting used medicated powder and solution is contained in respectively in described needle tubing and the described preceding ejector sleeve.
From said structure as can be seen, because medicated powder and solution have been contained in before syringe dispatches from the factory in the syringe, therefore, before injection, need not with easily work of contaminated pinhead such as syringe extract, mixes and extracts, both alleviate labor intensity, avoided the pollution of syringe needle again.
Fig. 1 is a kind of structural representation of the present invention.
As shown in Figure 1, the present invention is similar to traditional syringe, also comprises: needle tubing 12, ejector sleeve 22 and syringe needle 1.Syringe needle 1 is connected on the front end of needle tubing 12, and ejector sleeve 22 inserts in the needle tubing 12.
The difference of syringe of the present invention and conventional syringe is that ejector sleeve 22 is made up of two parts: preceding ejector sleeve 10 and back ejector sleeve 14, the external diameter of preceding ejector sleeve 10 can insert in the needle tubing 12 less than the internal diameter of needle tubing 12.The front end of pro-ejector sleeve 10 is provided with rubber top plug 9, and rubber top plug 9 fits tightly with needle tubing 12 inwalls.On rubber top plug 9, have a fenestra 6, post a thin film 7 on the fenestra 6.Back ejector sleeve 14 is double-decker, it is made of interior pipe 15A and outer tube 15B, in gap between pipe 15A and the outer tube 15B match with the pipe thickness of preceding ejector sleeve 10, after current ejector sleeve 10 inserts between the interior pipe 15A of back ejector sleeves 14 and the outer tube 15B, both connections that can be sealed and matched.Also have a push rod 11 on the back ejector sleeve 14, push rod 11 axially stretches out from the chimb 16 of back ejector sleeve 14, is provided with a tip 20 at its front end, and tip 20 is cone, and the conical base diameter is greater than the fenestra 6 on the preceding ejector sleeve 10 (its effect will be described later).
Characteristics of the present invention are that medicated powder and the solution with injection directly is contained in the syringe.As can be seen from Figure 1, separate before use, and both can easily mix when injection for making medicated powder and solution, therefore the present invention has designed above-mentioned structure, medicated powder can be contained in the needle tubing 12, and before solution is contained in the ejector sleeve 10, both be separated by thin film 7.Ejector sleeve 14 after injection Shi doctor or nurse can pushing and withstanding, back ejector sleeve 14 is relatively moved with preceding ejector sleeve 10, thin film 7 before the tip 20 of push rod 11 front ends punctures on ejector sleeve 10 fenestras 6,19 of solution flow in the needle tubing 12, mix with medicated powder 17, as ejector sleeve 14 behind the further pushing and withstanding, then cone tip 20 will block fenestra 6, prevent that solution 19 from flowing backwards, ejector sleeve 10 moves along needle tubing 12 inwalls before further then promoting again, injects.
Referring to Fig. 1, there is an adapter front end of needle tubing 12 and syringe needle 1 joint again, and syringe needle 1 joins with needle tubing 12 by taking over 5.The bore of the backshank 4 of syringe needle 1 afterbody is slightly larger than takes over 5, and its close-fitting is connected to be taken on 5.And in order to reach the purpose of sealing syringe needle 1, also dispose a needle guard 2 at syringe needle 1 place, also be provided with the contact pin pipe 3 that a bore, shape match with syringe needle 1 in the central interior of this needle guard 2, syringe needle 1 is inserted in the contact pin pipe 3, utilize the frictional force of syringe needle and contact pin pipe 3 inwalls to make it be the sealing shape, and the afterbody of needle guard 2 is enclosed within the periphery of backshank 4, utilize frictional force to make it be the sealing shape equally.
The present invention also has another advantage as can be seen from top description, promptly punctures after thin film 7 finishes to patient injection when tip 20, and syringe of the present invention is thoroughly stopped to be repeated to use promptly from useless.
