Abstract
A special injector for dispensation belongs to the technical field of medical instruments, which comprises a needle cylinder, a plunger, a needle plug and a double-cavity needle head. The injector is characterized in that the rear end of a guide tube on the upper face of the outer wall of the needle cylinder is communicated with an inner cavity which is arranged behind the plunger in the needle cylinder, adapters of the front ends of the guide tube and the needle cylinder are respectively connected with two needle seats which are arranged at the rear end of the double-cavity needle head, the inner wall of the rear end of the needle cylinder is fixed with a sealing ring, the cylindrical needle plug penetrates through the sealing ring to be connected with the plunger in the needle cylinder, and the cylindrical needle plug is connected with the sealing ring in a sliding and sealing mode. The injector has the advantages that as the outer wall of the needle cylinder is provided with the guide tube which is communicated with the inner cavity of the needle cylinder, air between the plunger and the sealing ring can enter or be discharged from medicine bottles through the guide tube when sucking and injecting medicine, and the insides of bottles cannot produce negative pressure or increase pressure. The injector is handy, convenient and quick in medicine sucking and injecting and saves time and labor.
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 usually finish with general common disposable syringe and liquid medicine is sucked syringe (suction medicine) maybe will suck the operation that liquid medicine in the syringe injects another sealed vial interior (injection) 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, and pumping velocity is slower; 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 strengthens thereupon.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and is inhaling medicine and during injection, operate the easy and convenient special syringe that makes up a prescription from bottle in bottle.
The purpose of this utility model is achieved in that this special syringe that makes up a prescription is made up of syringe, piston, pintle, two-chamber syringe needle, rear end of conduit above the syringe outer wall communicates with the inner chamber of syringe inner carrier back, and the joint of catheter proximal end and syringe front end links to each other with two needle stands of two-chamber syringe needle rear end respectively; The back end of syringe inwall is being fixed sealing ring, and cylindrical pintle passes the sealing ring that is connected with its slipper seal and links to each other with piston in the syringe.
Advantage of the present utility model: because the syringe outer wall is provided with the conduit that communicates with the syringe inner chamber, when inhaling medicine, injection, air between piston and the sealing ring just can enter or discharge medicine bottle by conduit, can not make to produce negative pressure in the bottle or pressure of the inside of a bottle is increased, the suction medicinal liquid is light, quick, 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 up of syringe 1, piston 2, pintle 3, two-chamber syringe needle 4, conduit 5 rear ends above syringe 1 outer wall communicate with the inner chamber of syringe 1 inner carrier 2 back, and the joint of conduit 5 front ends and syringe 1 front end links to each other with two needle stands of two-chamber syringe needle 4 rear ends respectively; Syringe 1 rear end inwall is being fixed sealing ring 6, and cylindrical pintle 3 passes the sealing ring 6 that is connected with its slipper seal and links to each other with piston 2 in the syringe 1.
