Abstract
A special syringe for dispensing belongs to the technical filed of medical instruments and comprises a needle tube, a piston, a needle bolt and a double-cavity syringe needle, wherein the piston with the needle bolt is slidably connected inside the needle tube in sealing manner. The special syringe for dispensing is characterized in that the double-cavity syringe needle is fixed onto the tube wall of the front end of the needle tube; anti-skid stripes are arranged on the outer wall of the needle tube; the rear end of the double-cavity syringe needle is parallel and level to the inner wall of the front end surface of the needle tube; the rear end of a liquid channel inside the double-cavity syringe needle is communicated with an inner cavity of the needle tube; and the rear end of a gas channel is communicated with the external. The special syringe for dispensing has the advantages that because the gas channel on the double-cavity syringe needle is constantly communicated with the external, pressure inside a medicine bottle can be timely adjusted when medicines are sucked from the sealed medicine bottle or medicines are injected into the sealed medicine bottle, thereby negative pressure is prevented from being produced inside the medicine bottle or the pressure inside the bottle is prevented from being increased, and liquid medicine suction and injection are enabled to be easy, rapid, time-saving and labor-saving. Moreover, the needle tube is easy to be clamped, has no remaining liquid medicines, and can avoid liquid medicine waste.
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 carry out dispensing operation with disposable ordinary syringe usually, have following shortcoming during with the ordinary syringe dispensing operation: the one, and ordinary syringe syringe outer wall is smooth, is difficult for clamping; The 2nd, there is medicinal liquid residual in the nipple of syringe front end all the time, cause liquid waste easily; The 3rd, inhale medicine in the sealed vial or in sealed vial, make easily during injection and produce negative pressure or messenger drug pressure of the inside of a bottle in the medicine bottle, make and take out injection liquid difficulty, waste time and energy, efficient is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of dispensing operation easy and convenient, avoids the special syringe that makes up a prescription of liquid waste.
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, the syringe slides within is being tightly connected and is having the piston of pintle, outer wall is provided with on the syringe front end barrel of anti-skidding striped and is fixing the rear end two-chamber syringe needle concordant with syringe front end face inwall, fluid passage rear end in the two-chamber syringe needle communicates with the syringe inner chamber, and the gas passage rear end communicates with the external world.
Advantage of the present utility model: because the gas passage above the two-chamber syringe needle communicates with the external world all the time, from sealed vial, inhale medicine or in sealed vial, can in time adjust pressure in the medicine bottle during injection, avoid making producing negative pressure in the medicine bottle or pressure of the inside of a bottle being increased, make that to take out injection liquid light, quick, time saving and energy saving; And the easy clamping of syringe, it is residual not have medicinal liquid, can avoid liquid waste.
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, the piston 2 that syringe 1 slides within is being tightly connected and is having pintle 3, outer wall is provided with on the syringe 1 front end barrel of anti-skidding striped and is fixing rear end and the concordant two-chamber syringe needle 4 of syringe 1 front end face inwall, fluid passage rear end in the two-chamber syringe needle 4 communicates with syringe 1 inner chamber, and the gas passage rear end communicates with the external world.
