Like this, to isolate filter type, infusion channel is isolated into and filters prepass and filter rear passage.From filtering the needle point that prepass inserts or being stopped by solid slab, or be bent hole and stop or be tilted hole and stop, thereby stopped needle point, further thrust.Filter membrane filtering chip, dual function, thus effectively prevent that broken needle and chip from entering passage after medical filtration assembly.
The purpose of this utility model can also realize by following approach.
About needle point, stop into part and have following further concrete selection:
Wherein: it is an a kind of lamellar member that needle point stops into part, its solid obstruction plate by central authorities and ring are trapped among a plurality of open-works as crossing liquid passage that stop plate periphery and form.
Another kind is: needle point stops into part and hidden and form along infusion channel axially spaced-apart is staggered by the solid obstruction plate of plural piece, and adjacent two to stop plate interval holes be liquid passage.
Another is: it is a kind of top seal that needle point stops into part, bottom opening, sidewall is distributed with the cylindrical member of a plurality of open-works, its external diameter is less than the aperture of the infusion channel that corresponding position is installed, the top of sealing is for stopping plate, there is a paragraph that aperture is larger in infusion channel stage casing, thereby there is former and later two steps, cylindrical member is installed on backward step, its top and front step have interval, interval between this interval and cylindrical member outside and infusion channel inwall and a plurality of open-works on cylindrical member sidewall and cylindrical member inner core chamber are sequentially communicated with the mistake liquid passage that forms bending.
About filter membrane, can there be following several further selections:
: filter membrane is an a kind of lamellar filter membrane, stops stacked together into part and is positioned at needle point and stops the rear into part with needle point.
Another kind is: filter membrane plug is located at needle point and stops crossing on liquid passage into part.
At this moment, needle point stops into part or the skeleton of filter membrane.
Filter membrane installation place preferably offers the steam vent being in communication with the outside, and in this steam vent, plug is provided with the venting plug of ventilative blocking solution.
Favourable like this medicinal liquid arrives and soaks filter membrane fast, allows filter membrane bring into play as early as possible filtering function, removes from and waiting for by the time of filter membrane aerofluxus.
The clamping of medical filtration assembly is between the joint pedestal and overlapping joint of split structure.
Overlapping joint lower end is a kind of upper mounting disc with indent of flange plate-like, and joint pedestal upper end is a kind of lower mounting disc with indent of flange plate-like, and Pharmaceutical filter assemblies is arranged in the inner cavity between this upper and lower mounting disc.
Overlapping joint or a kind ofly have needle adapter, or a kind of needleless joint, or a kind of have pull out the positive pressure connector that can produce forward liquid flow after transfusion device or syringe.
In sum, this utility model compared to existing technology tool has the following advantages: can effectively prevent that broken needle or chip from entering human vas, use safety, meanwhile, structure is compacter again.
