Abstract
A precise filter syringe comprises a syringe body and an injection needle. A liquid outlet of the syringe body is provided with a precise liquid medicine filter which comprises an upper casing and a lower casing, the upper casing is in ultrasonic welding connection with the lower casing, a precise liquid medicine filtering membrane is arranged in the lower casing, and the lower casing is provided with a liquid inlet matched with the liquid outlet of the syringe body. The lower casing is provided with a needle seat matched with the injection needle. The precise filter syringe is simple in structure, particles in filtered liquid medicines can be effectively filtered by arranging the precise liquid medicine filter on the syringe, the filtering precision is not larger than 0.22mum, and the precise filter syringe is convenient to operate and greatly improves safety of liquid medicine injection.
Description
Technical field
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of precise filtering injector.
Background technology
Syringe is widely used in clinical intramuscular injection medicinal liquid.But some medicinal liquid often contains the bigger insoluble substance of microgranule; Perhaps its solubility particle dissolution is insufficient; In case perhaps dissolving inadequate microgranule, these bigger microgranules get into human body through injector to inject; Circulate in vivo, finally greatly may cause angiemphraxis, and then cause even more serious harm.Inject the harm that some drug particle also can bring for a long time, hide health safety simultaneously.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, can secondary filter the precise filtering injector of microgranule in the medicinal liquid.
The technical scheme that this utility model is adopted in order to achieve the above object is following: a kind of precise filtering injector, comprise syringe body and entry needle, and the liquid outlet of said syringe body is provided with a precision liquid medicine filter.
Above-mentioned precision liquid medicine filter comprises upper casing and lower casing; Said upper casing adopts ultrasonic bonding to connect lower casing; One precision liquid medicine filter membrane places in the lower casing; Said lower casing is provided with the inlet that matches with the liquid outlet of syringe body, and said lower casing is provided with the needle stand that matches with entry needle.
Optimum, above-mentioned precision liquid medicine filter membrane is polypropylene screen, poly (ether sulfone) film or nylon membrane.
The beneficial effect of this utility model is: this utility model is simple in structure, through precision liquid medicine filter is set on syringe, and the effective microgranule in the filtering liquid medicine, filtering accuracy≤0.22 μ m, easy to operate, the safety that has improved liquid medicine injection greatly.
