Abstract
A special injector for dispensing belongs to the technical field of medical instruments, and comprises a needle cylinder, a dual-cavity injection-suction needle head, pistons and gear racks. The special injector for dispensing is characterized in that two circular cavities which are partitioned from each other and identical in size are arranged inside the needle cylinder of which the rear end is connected with a square sleeve, and connectors at the front ends of the cavities are respectively connected with two needle stands at the rear end of the dual-cavity injection-suction needle head; the gear racks are respectively and fixedly connected to the pistons inside the two cavities, two main drive gears provided with crank handles at the exteriors and respectively meshed with the two gear racks are fixed inside the sleeve between the rear ends of the gear racks through pin shafts, and driven gears meshed with the gear racks are respectively fixed inside the sleeves on the other side of each gear rack through rotating shafts. The special injector for dispensing has the advantages as follows: during the operations of medicine suction or medicine injection, negative pressure can not be generated inside a bottle or the pressure inside the bottle can not be increased, liquid medicine injection and suction are enabled to be more convenient, time-saving and labor-saving.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of special syringe that makes up a prescription.
Background technology
At present, medical personnel suck syringe with common disposable syringe with liquid medicine usually and maybe will suck liquid medicine in the syringe and inject operation in another sealed vial when making up a prescription from the medicine bottle of sealing.When inhaling medicine, the Jiao Gai that the disposable syringe syringe needle is passed in the medicine bottle bottleneck aspirates, and medicinal liquid is sucked out in the bottle of back and produces negative pressure, makes extraction difficult, the operation effort; During injection, also be that the Jiao Gai that syringe needle passes bottleneck is injected, the medicine of injection can occupy a bottle interior space, and pressure of the inside of a bottle is increased, and injects resistance and also strengthens thereupon.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and inhales medicine and in bottle during injection from bottle, easy and convenient, the time saving and energy saving special syringe that makes up a prescription.
The purpose of this utility model is achieved in that this special syringe that makes up a prescription is made of syringe, two-chamber notes suction spindle head, piston, tooth bar, the syringe inside that the rear end is connected with square casing is provided with two circular cavities of the identical space of size, and the joint of cavity front end links to each other with two needle stands that two-chamber is annotated suction spindle head rear end respectively; All be connected and fixed tooth bar on the piston of two cavity insides respectively, fix the driving gear that the outside of meshing respectively with two tooth bars has crank by bearing pin in the sleeve pipe between two tooth bar rear ends, in the sleeve pipe of each tooth bar opposite side, also fixing driven gear with the tooth bar engagement by rotating shaft respectively.
During use, rotate driving gear with handle, driving gear and driven gear can drive a tooth bar reach, a tooth bar retreats, thereby drive a piston reach, a piston retreats, and the piston that moves forward pushes the air in the cavity in the medicine bottle, the piston of Yi Donging sucks the liquid aliquot in the medicine bottle simultaneously backward, makes pressure of the inside of a bottle keep stable.
Advantage of the present utility model: when inhaling medicine or injection operation, can not make to produce negative pressure in the bottle or pressure of the inside of a bottle is increased, make that the suction medicinal liquid is easy and convenient, time saving and energy saving.
Description of drawings
Accompanying drawing is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this special syringe that makes up a prescription is made of syringe 1, two-chamber notes suction spindle head 2, piston 3, tooth bar 4, syringe 1 inside that the rear end is connected with square casing 5 is provided with two circular cavities of the identical space of size, and the joint of cavity front end links to each other with two needle stands that two-chamber is annotated suction spindle head 2 rear ends respectively; All be connected and fixed tooth bar 4 on the piston 3 of two cavity insides respectively, fix the driving gear 7 that the outside of mesh respectively with two tooth bars 4 has crank 6 by bearing pin in the sleeve pipe 5 between two tooth bar 4 rear ends, in the sleeve pipe 5 of each tooth bar 4 opposite side, also fixing the driven gear 8 that meshes with tooth bar 4 by rotating shaft respectively.
