Abstract
The invention provides a self-mixing injector. The self-mixing injector is used for medicament mixing while medicament suction and is characterized by comprising a needle cylinder, a pushing rod installed in the needle cylinder, a mixer located at the front end of the inside of the needle cylinder and a piston located at the front end of the pushing rod and connected with the needle cylinder in a sliding-sealing mode, wherein the mixer is provided with a mixer body and a spiral medicament channel penetrating through the mixer body. Due to the fact that the self-mixing injector is provided with the mixer and the mixer is provided with the spiral medicament channel, a medicament is fed into the needle cylinder through the spiral channel at a certain angle when being sucked, the speed is higher, and rotational medicament flow is formed in the needle cylinder. When suction of one medicament is completed and then another medicament is sucked, the medicament fed later is mutually mixed with the medicament fed early due to the effect of the rotational flow.
Description
Technical field
The present invention relates to a kind of from mixed water injection emitter, belong to medical instruments field.
Background technology
When to patient's injection medicament, sometimes need to be administered to patient again by after two kinds or the mixing of two or more different medicament, traditional syringe construction is fairly simple, the action of medicament mixing cannot be completed separately, need in advance two kinds of medicaments to be mixed in another container, row injection again after inhalation syringe.Not only operating procedure is many, and medicament can be made to be exposed in air ambient, brings contaminated risk.
Summary of the invention
The object of the present invention is to provide a kind of from mixed water injection emitter, to solve the problem.
Present invention employs following technical scheme:
The invention provides a kind of from mixed water injection emitter, for carrying out medicament mixed while absorption medicine, it is characterized in that, comprise: syringe; Push rod, is installed in syringe; Blender, is positioned at the front end of syringe inside; And piston, be positioned at the front end of push rod, with between syringe for slipper seal is connected; Wherein, blender has blender body and runs through the helically-shaped drug passage of blender body.
Preferably, of the present invention from mixed water injection emitter, can also have such feature: wherein, helically-shaped drug passage is two, and the direction of spiral is contrary.
Preferably, of the present invention from mixed water injection emitter, such feature can also be had: also comprise, mixing tab, be spiral lamellar, one end and blender are rotationally connected, the other end passes piston and stretches in push rod, piston and mixing tab joint have strip crevice, when pulling out push rod, drive mixing tab to rotate.
Preferably, of the present invention from mixed water injection emitter, can also have such feature: wherein, the medicine exit direction of helically-shaped drug passage is contrary with the rotation direction of mixing tab.
The beneficial effect of the invention
According to of the present invention from mixed water injection emitter, owing to having blender, and blender has spiral drug channel, therefore, when drawing medicine, medicine enters at a certain angle in syringe after helical duct, speed, thus in syringe, form the medicament flowing of rotation, when having drawn a kind of medicament, then when drawing another kind of medicament, after the medicament that enters mutually mix due to the effect of eddy flow with between the medicament first advanced into.
Accompanying drawing explanation
Fig. 1 is the profile from mixed water injection emitter;
Fig. 2 is the structural representation of blender.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
< embodiment one >
As shown in Figure 1 from mixed water injection emitter, comprising: syringe 11, push rod 12, mixing tab 13, blender 14, piston 15.
Push rod 12 is hollow structure, is installed in syringe 11.
Piston 15, is positioned at the front end of push rod 12, with between syringe for slipper seal is connected; And blender 14, be positioned at the front end of syringe 11 inside,
As shown in Figure 2, blender 14 has blender body and runs through the helically-shaped drug passage 141 of blender body.
In the present embodiment, helically-shaped drug passage 141 is two.The gap passed through for medicinal liquid is left between helically-shaped drug passage 141 and the front end of syringe, therefore, when pulling back piston, medicinal liquid enters in the space of syringe after entering from the suction nozzle of syringe after helically-shaped drug passage 141, because spiral passage makes the flow direction of medicinal liquid become revolution flowing, therefore medicinal liquid is when flowing out from the outlet of helically-shaped drug passage 141, there is the power of rotation, make medicinal liquid form eddy flow after injection syringe, have the effect of further thread mixing.
Mixing tab 13, be spiral lamellar, one end and blender 14 are rotationally connected, and the other end passes piston 15 and stretches in push rod 12.Piston 15 and mixing tab 13 joint have strip crevice, for slipper seal is connected between mixing tab with gap.When pulling out push rod 12, mixing tab 15 is driven to rotate.Therefore mixing tab 15 rotates while medicinal liquid enters, and further mixes medicinal liquid.The medicine exit direction of helically-shaped drug passage 141 is contrary with the rotation direction of mixing tab 13, to increase the effect of mixing.
< variation one >
In this variation, substantially identical with embodiment one from the basic structure of mixed water injection emitter, difference is: the direction of the spiral of two helically-shaped drug passages 141 is contrary, make when medicinal liquid flows out from the outlet of helically-shaped drug passage 141, flow direction is contrary, thus increases the effect of mixing further.
