Abstract
An injection-absorption needle for dosage belongs to the technical field of medical machinery, and comprises a needle rod (1), a needle holder (2) and an air filter (3). The injection-absorption needle is characterized in that a needle point is a solid double-cavity needle rod (1); the inner portion of the needle point is divided into a liquid passage (4) and a gas passage (5); a liquid inlet-outlet hole (6) communicated with the liquid passage (4) is arranged on the lateral wall of the needle rod (1) close to the solid position of the needle point; a gas hole (7) communicated with the gas passage (5) is arranged on the lateral wall of the middle upper portion of the needle rod (1); the upper end of the liquid passage (4) is communicated with the needle holder (2); and the upper end of the gas passage (5) is communicated with the air filter (3). The injection-absorption needle has simple structure and convenient use, enables pressure inside a medicine bottle to be kept balanced when in medicine absorption or medicine injection, is simple and convenient in dosage operation, time-saving and labor-saving, and causes no pollution to medicine liquid and indoor air of air after being filtered by the air filter.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of making up a prescription with annotating the suction spindle head.
Background technology
At present, medical personnel generally carry out dispensing operation with common disposable syringe, are about to liquid medicine and suck syringe (suction medicine) maybe will suck the interior medicinal liquid of syringe and inject the medicine bottle (injection) of another sealing from the medicine bottle of sealing.The Jiao Gai that when inhaling medicine the syringe needle above the syringe is passed above the medicine bottle bottleneck carries out drawing liquid, after medicinal liquid is sucked out, can make to produce a negative pressure in the bottle, makes extraction difficult; Also be that the Jiao Gai that the syringe needle above the syringe passes above the medicine bottle mouth is injected during injection, pressure of the inside of a bottle increased after the medicinal liquid of injection occupied bottle interior space, injected resistance and also increased thereupon, made whole dispensing operation waste time and energy.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can keep balance by the messenger drug pressure of the inside of a bottle when inhaling medicine or injection, and what dispensing operation was easy and convenient makes up a prescription with annotating the suction spindle head.
The purpose of this utility model is achieved in that this makes up a prescription and is made up of shank, needle stand, air filter with annotating suction spindle head, needle point is that solid two-chamber shank inside is divided into fluid passage and gas passage, shank sidewall near the solid place of needle point is provided with the liquid inlet/outlet that communicates with fluid passage, and shank middle and upper part sidewall is provided with the pore that communicates with gas passage; The fluid passage upper end is connected with needle stand, and the gas passage upper end is connected with air filter.
Advantage of the present utility model: simple in structure, easy to use, when inhaling medicine or injection, can keep balance by the messenger drug pressure of the inside of a bottle, dispensing operation is easy and convenient, and is time saving and energy saving, and air can not pollute medicinal liquid and room air after air filter filters.
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 makes up a prescription and is made up of shank 1, needle stand 2, air filter 3 with annotating the suction spindle head, needle point is that solid two-chamber shank 1 inside is divided into fluid passage 4 and gas passage 5, shank 1 sidewall near the solid place of needle point is provided with the liquid inlet/outlet 6 that communicates with fluid passage 4, and shank 1 middle and upper part sidewall is provided with the pore 7 that communicates with gas passage 5; Fluid passage 4 upper ends are connected with needle stand 2, and gas passage 5 upper ends are connected with air filter 3.
Claims (1)
1. one kind is made up a prescription with annotating the suction spindle head, form by shank (1), needle stand (2), air filter (3), it is characterized in that needle point is that solid two-chamber shank (1) inside is divided into fluid passage (4) and gas passage (5), shank (1) sidewall near the solid place of needle point is provided with the liquid inlet/outlet (6) that communicates with fluid passage (4), and shank (1) middle and upper part sidewall is provided with the pore (7) that communicates with gas passage (5); Fluid passage (4) upper end is connected with needle stand (2), and gas passage (5) upper end is connected with air filter (3).
