Abstract
A disposable closed type dispenser belongs to the technical field of medical instruments and comprises a needle cylinder, a pintle, a piston, a conduit I, a conduit II, a duplex-cavity puncture needle I and a duplex-cavity puncture needle II, wherein the internal of the needle cylinder is connected with the piston with the pintle thereon in a sliding seal way. The disposable closed type dispenser is characterized in that the side wall at the front end of the needle cylinder is respectively connected with the conduit I and the conduit II that are provided with switches on the mutually-symmetrical upper sides, the outer end of the conduit I is communicated with the liquid on the duplex-cavity puncture needle I through a hose, the outer end of the conduit II is communicated with the liquid on the duplex-cavity puncture needle II, and the gas channel on the duplex-cavity puncture needle I and that on the duplex-cavity puncture needle II are respectively communicated with the external. The disposable closed type dispenser has a simple structure and convenience in operation, and is time-saving and labor-saving; and the whole dispensing process can be finished in a closed state without inserting a needle head repeatedly, the appliance is prevented from being polluted, and the working efficiency is improved.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically disposable closed dispenser.
Background technology
In clinical treatment, the most frequently used treatment means is transfusion, making up a prescription is a link in the infusion process, at first to insert and extract lysate in the liquid bottles out with syringe, inserting interior reuse syringe after the dissolving evenly of powder medicine is released of powder medicine bottle then is injected in the liquid bottles, this suction medicine or injection operation will be carried out repeatedly sometimes, its shortcoming is: operate loaded down with trivial details, waste time and energy, the insertion repeatedly of syringe needle or extract easily and polluted, and when inhaling medicine or injection operation, make easily and produce negative pressure or malleation in liquid bottles or the powder medicine bottle, make to take out and annotate difficulty, the speed of making up a prescription is slack-off, influences work efficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy to operate, time saving and energy saving, does not need to insert repeatedly syringe needle can be finished the whole process of making up a prescription under closed state disposable closed dispenser.
The purpose of this utility model is achieved in that this disposable closed dispenser is by syringe, pintle, piston, conduit I, conduit II, two-chamber puncture needle I, two-chamber puncture needle II forms, above being tightly connected, the syringe slides within is provided with the piston of pintle, the syringe front end side wall is connected with conduit I and the conduit II that has switch above symmetrical respectively, conduit I outer end is connected with fluid passage above the two-chamber puncture needle I by flexible pipe, conduit II outer end is connected with fluid passage above the two-chamber puncture needle II by flexible pipe, and two-chamber puncture needle I and the gas passage above the two-chamber puncture needle II communicate with the external world respectively.
During use, two-chamber puncture needle I, two-chamber puncture needle II are inserted respectively in liquid bottles and the powder medicine bottle, open the switch above the conduit I, the switch above the closure catheter for closing II, outwards spurring pintle can be with in the liquid suction syringe; And then open switch above the conduit II, and the switch above the closure catheter for closing I, promoting pintle can be injected into the liquid in the syringe in the powder medicine bottle, and vice versa; Because two-chamber puncture needle I and the gas passage above the two-chamber puncture needle II communicate with the external world respectively, make that the pressure in liquid bottles and the powder medicine bottle keeps stable, easily easy when taking out injection liquid.
Advantage of the present utility model: simple in structure, easy to operate, time saving and energy saving, do not need to insert repeatedly syringe needle and can under closed state, easily finish the whole process of making up a prescription, and can avoid utensil to be polluted, increase work efficiency.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this disposable closed dispenser is by syringe 1, pintle 2, piston 3, conduit I 4, conduit II 5, two-chamber puncture needle I 6, two-chamber puncture needle II 7 forms, above being tightly connected, syringe 1 slides within is provided with the piston 3 of pintle 2, syringe 1 front end side wall is connected with conduit I 4 and the conduit II 5 that has switch above symmetrical respectively, conduit I 4 outer ends are connected by the fluid passage above flexible pipe and the two-chamber puncture needle I 6, conduit II 5 outer ends are connected by the fluid passage above flexible pipe and the two-chamber puncture needle II 7, and two-chamber puncture needle I 6 and the gas passages above the two-chamber puncture needle II 7 communicate with the external world respectively.
