There are many injecting drug uses to store for convenience at present and guarantee that drug effect need make powder or lyophilized preparation, need to suck lysate in use and reinject in drug powder or the lyophilized preparation, make it to dissolve the reuse syringe and suck medicinal liquid and implement injection with syringe.Therefore in use bring the risk of pollution, and troublesome poeration.Chinese patent " medicine storage type injectable powder combination medicine adding syringe ", the patent No.: 200320109812.7, a kind of syringe was once disclosed.This patent can make lysate inject in the solute bottle by communicating pipe under the external force effect that pushes away handle and piston, with medicated powder dissolve even after directly to patient infusion or join in the infusion bottle.But this syringe processing technology more complicated, and be not inconsistent with the conventional injector mould, can not satisfy special needs, need be as cooperating surgery with chemical spray in wound surface.In addition, the syringe of this patent disclosure is provided with two prong heads, pierce through isolated part between lysate and the medicated powder by external force, realize the mixing between lysate and the medicated powder, after syringe needle inserts human body, utilize its counteracting force, this may increase exerting oneself of injection, even brings bigger misery to the patient.
The utility model content
The purpose of this utility model is to provide a kind of powder and solvent of being equipped with in advance, and is easy and simple to handle, can with the injection device of the fine compatibility of existing injection tool.
The injection device that powder and solvent are housed in advance that this utility model provides is made up of push-pull bar, inner core, urceolus, piston, Feng Zui, solvent and powder, it is characterized in that solvent places in the inner core cavity, inner core one end is connected with piston by interior nozzle, and be placed in the cavity of urceolus, the other end of inner core has a push-pull bar to place in it, and powder is placed in the urceolus cavity, and the injection port of urceolus is a standard size, and seal with the envelope mouth, the piston mouth seals with paster or one-way cock.
A kind of injection device that powder and solvent are housed in advance provided by the utility model, it is characterized in that solvent can be made into the solvent bag, one end of the inner nozzle of solvent bag is suppressed with jagged lines, zigzag partly approaches but sealing, under the extruding of push-pull bar, break easily, make solvent can flow in the urceolus and mix with powder.
Can be between a kind of injection device that powder and solvent are housed in advance provided by the utility model, described envelope mouth and injection port by being threaded, clamping, pegging graft or be nested tightening seal.
A kind of injection device that powder and solvent are housed in advance provided by the utility model, described paster or one-way cock are placed on interior tube port position, make solvent to flow in the urceolus smoothly.In described paster or one-way cock can also be placed between nozzle and the piston mouth any one.
A kind of injection device that powder and solvent are housed in advance provided by the utility model can use two same injection devices provided by the utility model together, forms the duplex syringe with reference to Chinese patent ZL99240314.6 " duplex syringe ".
The injection device that powder and solvent are housed in advance that this utility model provides is compared with existing syringe and patent has remarkable result:
1, because injection port is a standard size, therefore can add suitable connection syringe needle or shower nozzle, make up, need not to make in addition complicated die, help producing and the clinical expansion use according to different needs.
2, the injection device that powder and solvent are housed in advance that provides of this utility model has overcome the shortcoming of prior art, and simple in structure, handling ease need not complicated die, operation is convenient, and can satisfy multiple needs.
3, the injection device that powder and solvent are housed in advance that provides of this utility model need not to pierce through isolated part between lysate and the medicated powder by external force, can put various syringe needles or nozzle as required, injects or sprays, and is easy to use.
4, the injection device that powder and solvent are housed in advance that provides of this utility model need not to pierce through isolated part between syringe needle and the medicinal liquid by external force, can reduce to the patient and bring bigger misery.
This injection device is easy to use, during use, holds inner core and promotes the push-and-pull thick stick, squeezing broken thin film paster under external force or washing one-way cock open makes solvent push urceolus by aperture, after powder dissolved mixing, take off the envelope mouth, socket syringe needle or nozzle use as required.Just with powder and solvent fill according to dosage, production technology is convenient when producing for this injection device, is fit to large-scale production.Whole injection device is aseptic packaging, disposable use.Avoided in the present clinical use powder injection process because the pollution risk and the troublesome poeration that need secondary transferring solvent and medicinal liquid to bring are safe in utilization easy.
