Abstract
The invention discloses a precise liquid medicine filter, which belongs to medical instruments and structurally comprises an upper cover, a lower cover, a liquid inlet nozzle and a liquid outlet nozzle. The upper cover is fastened with the lower cover, an upper cover ring is arranged on the inner side of the upper cover, a water flowing hole is arranged on the upper cover ring, the liquid inlet nozzle and the liquid outlet nozzle are respectively arranged at two ends of the lower cover, a plurality of exhaust holes are arranged on the upper cover, a liquid collecting groove is arranged in the middle of the lower cover, the liquid outlet nozzle is communicated with the liquid collecting groove, the liquid collecting groove is a U-shaped groove, and a plurality of bumps which are arrayed like a tree are disposed on the lower cover at two ends of the liquid collecting groove. The precise liquid medicine filter has the advantages that bubbles generated in a transfusion process are discharged so as to realize safety transfusion, a space between the upper cover and the lower cover is enlarged, the difficult problem that the bubbles are detained on a liquid inlet level and a liquid outlet level of the precise liquid medicine filter during usage is resolved, liquid medicine guiding is fast, exhaust speed is increased, and the like.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially a kind of medicinal liquid accurate filter.
Background technology
Play the garter transfusion, may the particulate matter external world, that produce in the operation be brought in the medicinal liquid, bring in the human body blood vessel through transfusion inadvertently; Having does not into have, and has just become secular latency harm, with blood operation; Wait for an opportunity to cause all size disease, hidden danger is very big.These people have been recognized progressively the product of corresponding construction also releases one after another.But employed medicinal liquid accurate filter is gone up in medical treatment now; In clinical transfusion process herb liquid, usually have air to produce, on the wall of the bubble that has attached to infusion tube, what have then gets into human body with medicinal liquid; Big bubble gets into human body through being circulated to pulmonary; Can cause air embolism, cause patient's death by suffocation, the bubble of therefore infusing seriously jeopardizes patient's life security.And the loam cake of medicinal liquid accurate filter and the space between the lower cover are little, and medicinal liquid flows not smooth, and the aerofluxus bubble is slow.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to above-mentioned deficiency of the prior art a kind of medicinal liquid accurate filter to be provided; This a kind of medicinal liquid accurate filter has and can the bubble that produce in the infusion process be discharged; Realize safe infusion, the space between loam cake and the lower cover is increased, solved the difficult problem that the medicinal liquid accurate filter in use steeps into and out of the liquid level remained gas; The medicinal liquid water conservancy diversion is fast, increases the characteristics of exhaust velocity.
The technical solution adopted for the present invention to solve the technical problems is: it comprises loam cake, lower cover, liquid inlet and fluid mouth; Described loam cake and lower cover are interlocked, and the inboard of described loam cake is provided with decorative cover, and the described decorative cover of going up is provided with the discharge orifice; Described lower cover two ends are respectively arranged with liquid inlet and fluid mouth; Described loam cake is provided with a plurality of steam vents, and the middle part of described lower cover is provided with collecting tank, and described fluid mouth is connected with collecting tank; Described collecting tank is a U type groove, and the two ends lower cover of described collecting tank is provided with the convexity of a plurality of tree-shaped arrangements.
Described convexity is 4, is symmetrically distributed along the collecting tank two ends.
Described steam vent is 3, evenly is provided with along loam cake.
Described liquid inlet and fluid mouth are respectively extension tube attached.
Described liquid inlet and fluid mouth are respectively inner connecting tube.
Described loam cake and lower cover are rhombus.
A kind of medicinal liquid accurate filter of the present invention is compared with prior art, and have following outstanding beneficial effect: loam cake is provided with steam vent, can the bubble that produce in the infusion process be discharged; Realize safe infusion, lower cover is provided with the convexity and the collecting tank of a plurality of tree-shaped arrangements, and the space between loam cake and the lower cover is increased; Solved the difficult problem that the medicinal liquid accurate filter in use steeps into and out of the liquid level remained gas; Characteristics such as the medicinal liquid water conservancy diversion is fast, increases exhaust velocity, and is easy to use.
