Enter human vas, observe infusion last line of defense, ensure that patient's is healthy and safe.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that a kind of accurate positive pressure connector,
Including positive pressure infusion connector, cavity is equipped with inside the positive pressure infusion connector, is mounted with silica gel joint in the cavity, it is described just
The bottom of pressure infuser connector is successively arranged the First stratum to connect and second step layer, the First stratum with second
Filter membrane is equipped between stratum, the material of the filter membrane is poly (ether sulfone) film material.
Further, the aperture of the filter membrane is 0.03um-10um.
Further, silica gel joint is mounted in the cavity.
Further, the cavity inside is equipped with support column, and the support column outer wall is arranged with elastic device, the support
Top end is connected with connector.
The utility model has the beneficial effects that can be realized multilayer stereo structure by filter membrane, it is micro- precisely to filter rubber
Grain, glass fibre and insoluble drug particle etc. enter human vas with medical fluid, observe infusion last line of defense, ensure that disease
People's is healthy and safe, can not only guarantee filter efficiency using poly (ether sulfone) film material, and possesses ultra high rate and superpower receive dirt
Ability.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
