Abstract
A blockage-free infusion device capable of achieving free degassing is matched with a novel structure and mainly comprises an upstream liquid filtering unit, a downstream degassing unit and an infusion pipeline. The upstream liquid filtering unit comprises a liquid filtering membrane, a filter shell and an exhaust membrane or an exhaust columnar device which is arranged on or not arranged on the shell. The downstream degassing unit comprises a through hole gas blocking mesh membrane, a degassing exhaust membrane and a degassing shell, wherein the through hole gas blocking mesh membrane directly seals and covers an inner opening of a liquid outlet pipe in the degassing shell. According to the blockage-free infusion device capable of achieving free degassing, the two functions of liquid filtering and universal free posture degassing are separately designed, and meanwhile the effects that necessary selective filtering is carried out when particle medicine is infused, the smooth liquid blockage-free passing is maintained in the degassing link, and bubbles are effectively intercepted are taken into consideration.
Description
Technical field
The present invention relates to one in the infusion set field under natural gravity condition without blocking freely degassed transfusion device, particularly relate to the liquid filtering installed in the gravity liquid input process in a kind of medical field and bubble tackles the corresponding technology removed, solve liquid endoparticle in liquid input and bubble subtractive process to remove bubble used block the problems such as gas material generation blocking in various degree and flow velocity cataclysm.
Technical background
Up to now, the liquid filtering of transfusion device is all use a same diaphragm to complete with degassed, or the filter membrane of the filter membrane of straight-through hole shape or nonwoven (sponge), because the area of liquid filtering film is large, solution can not be taken into account for the filtering function of liquid and the degassed function of bubble-free, when particularly requiring that free attitude is degassed, any large-area film all can not realize, namely still there is a chamber in liquid filtering film downstream, some Position Design in chamber have liquid outlet, therefore when liquid enters in filter membrane rear chamber through filter membrane, liquid produces eddy current, can form gas-liquid mixture fluid enters in downstream pipe, up to now, the particle filtering function of transfusion and the degassed functional separation of transfusion are not considered to design separately with each.
The application number of application in I on May 23rd, 2013 be 201310193579.3 patent of invention " infusion safety degassed insurance system structure " still do not find out immanent structure and the relation each other of upper and lower 2 tunics clearly, just solve the problem no longer producing reboil bubble after degassing, do not relate to granule by time the solution of blocking that causes, the current selection related to has the bubble pressure point that the usual standard of blocking air film of tackling bubble function is less hole and Geng Gao, to this generally select be the film material of sponge structure (such as, PES polyether sulfone materials), therefore when inputting granule medicament, " indifference " is caused to filter, no matter granular size all forms interception, in reality test, finally cause the problems such as the blocking of accumulation property and flow velocity cataclysm to occur, not clear and definite in the structure of liquid filtering film yet, the blocking of accumulation property and flow velocity change is produced when also causing granule medicament to input.
Therefore the present invention in depth proposes the innovation scheme that becomes more meticulous further, effective ingredient granule should be let slip again by selectivity interception impurity granule when inputting granule medicament, therefore the particle size distribution of granule medicament will not only clearly be studied, also to make the granule medicament overwhelming majority can by liquid filtering film and all tackle nethike embrane by bubble, also will tackle the impurity particle defining particle diameter and interception and the visible bubble of eliminating simultaneously.
Summary of the invention
In order to the deficiency of the patented technology that solves problem existing for above-mentioned prior art and declared before me, the invention provides the nothing blocking freely degassed transfusion device of a kind of brand new collocation, mainly comprise: upstream liquid filter element, downstream degas module and infusion pipeline, wherein, upstream liquid filter element comprises with little or no exhaust membrane or aerofluxus cylindrical device on liquid filtering film and filter housings and housing, wherein, downstream degas module comprises through hole and blocks gas nethike embrane, degassed exhaust membrane and degassed housing, through hole blocks gas nethike embrane and is directly sealed on the drain pipe internal orifice of degassed enclosure interior, connection between upstream liquid filter element and downstream degas module comprises soft or hard two kinds of mode of communicating, namely to be hose connectionly connected with structure fusion, the aperture that through hole blocks gas nethike embrane is in addition more than or equal to the aperture of liquid filtering film.Wherein through hole blocks on gas nethike embrane and is designed with the directly through straight channels structure in two sides, the shape of straight channels is tetragon or sub-circular, through hole block straight channels on gas nethike embrane form each other and size basically identical, system design for input particulate drug is the liquid filtering film that the upstream of blocking gas nethike embrane at the through hole of straight channels installs equally with straight channels form, the average pore size of the straight channels that through hole blocks on gas nethike embrane is greater than the average pore size of the straight channels on liquid filtering film, namely the granule that can leak through liquid filtering film in liquid is less than the hole that through hole blocks the straight channels on gas nethike embrane, the shape that through hole blocks the straight channels on gas nethike embrane is tetragon or sub-circular, wherein said tetragon hole is woven to surround by graticule to be formed, wherein said sub-circular hole punches or/and the sub-circular through hole of corrosion formation on monofilm, the through hole of above-mentioned two kinds of shapes, design for the bubble point pressure of water is at 2 to 20 kPas.Both the liquid filtering film can installed with straight channels in the upstream that the through hole with straight channels blocks gas nethike embrane also can install the liquid filtering film of random (nonwoven or sponge) hole and the mix and match of two kinds of filter membranes, i.e. three kinds of integrated modes, (1) through hole blocks the integrated mode of the liquid filtering film of gas nethike embrane and through duct form, (2) through hole blocks the integrated mode of the liquid filtering film of gas nethike embrane and random (nonwoven or sponge) hole, (3) the liquid filtering film that through hole blocks gas nethike embrane and through duct form loads in mixture the Three models such as the liquid filtering film of random (nonwoven or sponge) hole.
。In addition, the aperture in the through duct that through hole blocks on gas nethike embrane be greater than liquid filtering film by granule external diameter, the granule external diameter that can leak through liquid filtering film namely in liquid is less than the aperture that through hole blocks the through duct on gas nethike embrane.In order to ensure that bubble is discharged and do not had at " dead angle ", the work area that in design, employing through hole blocks gas nethike embrane is less than the work area of degassed exhaust membrane, and is aligned the working region of exhaust membrane and cover the top that through hole blocks gas nethike embrane.The described through hole with straight channels blocks gas nethike embrane and also can be used alone, and not with the liquid filtering film conbined usage of upstream, finally only realize the interception to bubble within fluid and eliminating function, the described through hole with straight channels blocks the design of gas nethike embrane average pore size scope between 5 microns to 30 microns, for the graininess liquid containing different-grain diameter, be used alone through hole block gas nethike embrane and without upstream liquid filter membrane time, the particle diameter that through hole be made to block gas nethike embrane average pore size be greater than the most of granules in liquid.
