The invention relates to the technical field of medical instrument equipment, in particular to a syringe capable of providing convenience for dispensing medicine. The syringe mainly comprises a double-cavity needle head and a filtering needle tube; the double-cavity needle head comprises a connection base coaxially connected with a hollow needle; the outer wall of the connection base is provided with an air passage penetrating through the inside and outside; the interior of the hollow needle is separated into a first passage and a second passage which are formed side by side through an axiallypenetrating partition plate; the first passage is communicated with the interior of the connection base, and the second passage is communicated with the air passage; the filtering needle tube is of anested cylinder piston structure, the front end of a cylinder is provided with a connector communicated with the inside of the cylinder, and the connector is coaxially and cooperatively nested in theconnection base and internally provided with a filtering body; a piston is connected with a push rod, and the push rod extends outward through the end, away from the connector, of the cylinder. The syringe aims at adopting the mode of adding the air pressure balance passage into the needle head for solving the problem that it is extremely laborious to pump liquid medicine.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to an easy-to-dispensing syringe. Background technique [0002] Syringes are a common medical appliance. As early as the 15th century, Italian Catinel proposed the principle of syringes. The needle is mainly used to extract or inject gas or liquid. The syringe can also be used for medical equipment, containers, and scientific instruments such as some chromatography to inject through the rubber septum. The existing syringe is inconvenient when dispensing medicine, and the syringe is used to suck the liquid medicine. The time is extremely laborious, and in this process, the bottle needs to be shaken constantly to speed up the mixing of the medicinal liquid, which consumes a lot of manpower, thereby reducing the dispensing efficiency. Contents of the invention [0003] The object of the present invention is to provide an easy-to-dispensing syringe, which solves the problem...
