Abstract
A medical dosing apparatus belongs to the technical field of medical instruments and consists of a needle tube, a catheter, a double-cavity needle head, pistons, a connecting rod and a handle. The medical dosing apparatus is characterized in that the rear end of the catheter attached and fixed on the outer wall of the needle tube is communicated with an inner cavity at the rear end of the needle tube, the front end of the catheter and a nipple at the front end of the needle tube are respectively connected with a needle seat at the rear end of the double-cavity needle head, two pistons in the needle tube are connected through the connecting rod, and the handle vertically fixed in the middle of the connecting rod penetrates through symmetrical axial through holes on the wall of the needle tube to be exposed outside the needle tube. The medical dosing apparatus has the advantages that due to the catheter arranged on the outer wall of the needle tube and communicated with the inner cavity at the rear end of the needle tube, air in the hollow cavity at the rear end of the needle tube flows in or is exhausted from a medicine bottle through the catheter and the double-cavity needle head when in medicine suction or injection, negative pressure in the bottle or increase of pressure in the bottle is avoided, and accordingly liquid medicine can be sucked and injected conveniently and quickly in a labor-saving and time-saving manner.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of medical dispenser.
Background technology
At present, medical personnel finish with common disposable syringe usually 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 easy and convenient medical dispenser from bottle in bottle.
The purpose of this utility model is achieved in that this medical dispenser is made up of syringe, conduit, two-chamber syringe needle, piston, connecting rod, handle, adhere to the rear end of conduit and the back end of syringe intracavity inter-connection that are fixed on above the syringe outer wall, the nipple of front end and syringe front end links to each other with the needle stand of two-chamber syringe needle rear end respectively; Two pistons in the syringe link to each other by connecting rod respectively, and the handle that is vertically fixed on the connecting rod middle part is exposed at the syringe outside after passing symmetrical axially extending bore above the syringe barrel respectively.
Advantage of the present utility model: because the syringe outer wall is provided with the conduit that communicates with the back end of syringe inner chamber, when inhaling medicine or injection, air in the back end of syringe cavity just can enter or discharge medicine bottle by conduit and two-chamber syringe needle, 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 medical dispenser is made up of syringe 1, conduit 2, two-chamber syringe needle 3, piston 4, connecting rod 5, handle 6, adhere to conduit 2 rear ends and the syringe 1 rear end intracavity inter-connection that are fixed on above syringe 1 outer wall, the nipple of front end and syringe 1 front end links to each other with the needle stand of two-chamber syringe needle 3 rear ends respectively; Two pistons 4 in the syringe 1 link to each other by connecting rod 5 respectively, and the handle 6 that is vertically fixed on connecting rod 5 middle parts is exposed at syringe 1 outside after passing symmetrical axially extending bore 7 above syringe 1 barrel respectively.
Claims (1)
1. medical dispenser, form by syringe (1), conduit (2), two-chamber syringe needle (3), piston (4), connecting rod (5), handle (6), it is characterized in that adhering to and be fixed on conduit (2) rear end and syringe (1) the rear end intracavity inter-connection of syringe (1) above the outer wall, the nipple of front end and syringe (1) front end links to each other with the needle stand of two-chamber syringe needle (3) rear end respectively; Two pistons (4) in the syringe (1) link to each other by connecting rod (5) respectively, are exposed at syringe (1) outside after the handle (6) that is vertically fixed on connecting rod (5) middle part passes the symmetrical axially extending bore (7) of syringe (1) above the barrel respectively.
