Abstract
The present invention discloses a precision liquid medicine filter used for transfusion in human and a method for preparing the same. The precision liquid medicine filter has large flow of liquid medicine and stabile flow velocity at same time, which includes filter seat, filter cover, filter membrane, hydrophobe membrane; said filter seat has liquid inlet end and outle end, the liquid inlet end of filter seat links with liquid outlet end by seat core, said liquid outlet end is on same straight line with liquid outlet end; the filter membrane is fixed on the end of said filter seat core and liquid outlet end, and forms a cavity in seat core end, filter membrane and liquid outlet end; said liquid inlet end has space with seat core end, so the liquid medicine can enter into cavity of the filter; said filter cover has air outlet hole, the hydrophobe membrane is fixed on air outlet hole of said filter cover inner wall; said filter cover conjugates with filter seat each other and is fixed linkes, and forms a cavity in filter membrane, liquid inlet end, filter cover. It has characteristics that can reduce resistance caused by large flow transfusion to great extent, and random position of filter can exhaust etc.
Description
Technical field
The present invention relates to a kind of liquid medicine filter, especially relate to a kind of crowd at when transfusion used precision liquid medicine filter and preparation method thereof.
Background technology
In the patent No. is 200520115832.4, name is called in the Chinese patent of liquid medicine filter and discloses a kind of like this filter, by upper casing, filtration membrane, the lower casing of drag-out pipe, described upper casing and the mutual equality of lower casing of band feed tube and be with inner chamber etc. to form, direction and the medicinal liquid of medicinal liquid by described filtration membrane is perpendicular from the direction that the liquid feeding end of housing flows to liquid outlet; On the described upper casing air-vent is arranged, described air-vent place and diaphragm is arranged on inner walls.Used filter all follows the described filter of this patent similar on the market now, when this filter uses clinically, seem not enough in quick transfusion of solution short time and long-time large capacity transfusion, yet in actual clinical, need this long-time liquid medicine filter of flow greatly to be used.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of in the identical time precision liquid medicine filter and preparation method thereof of the big and flow speed stability of the medicinal liquid flow by filter.
Precision liquid medicine filter of the present invention comprises filter seat, strainer cover, filter membrane, hydrophobic membrane; Described filter seat has liquid feeding end and liquid outlet, by the seat core both is linked into an integrated entity between the liquid feeding end of filter seat and liquid outlet, and described liquid feeding end and liquid outlet are on same straight line; Be fixed with filter membrane on the end of described filter seat core and the liquid outlet, make to form a cavity between seat core end, filter membrane, the liquid outlet; Described liquid feeding end has at interval with seat core end, makes medicinal liquid enter in the cavity of filter; Described filter is stamped venthole, and the venthole place is fixed with hydrophobic membrane on the inwall of described strainer cover; Described strainer cover cooperatively interacts and fixedlys connected with filter seat and is integral, and forms a cavity between filter membrane, liquid feeding end, strainer cover.
Make by the following method according to above-described precision liquid medicine filter: the one, utilize mold injection to become required form filter seat, strainer cover; The 2nd, behind the injection molded, moulding is warmed to the 40-100 degree, be incubated 12-24 hour, cooling; The 3rd, filter membrane is welded to ultrasonic welding machine on the relevant position of filter seat, utilize ultrasonic welding machine to be welded on the relevant position of strainer cover hydrophobic membrane; The 4th, with ultrasonic welding machine that strainer cover and filter seat is integrally welded.
Farthest lowered the resistance that big flow transfusion produces according to above-described precision liquid medicine filter, simultaneously the optional position of filter can aerofluxus, can guarantee the needs of clinical big flow transfusion, result of use is more obvious during long-time the transfusion, preparation technology is simple simultaneously, the junction firmness and the stability of filter are improved, and this technology has avoided adopting the pollution problem of conventional bonding agent connecting band rice.
Figure of description
Fig. 1 is a structural representation of the present invention.
The specific embodiment
In Fig. 1, precision liquid medicine filter of the present invention comprises filter seat 1, strainer cover 2, filter membrane 3, hydrophobic membrane 4; Described filter seat 1 has liquid feeding end 5 and liquid outlet 6, by seat core 7 both is linked into an integrated entity 6 of the liquid feeding end 5 of filter seat and liquid outlets, and described liquid feeding end 5 and liquid outlet 6 are on same straight line; Be fixed with filter membrane 3 on the end of described filter seat core 7 and the liquid outlet 6, make to form a cavity between seat core 7 ends, filter membrane 3, the liquid outlet 6; Described liquid feeding end 5 has at interval with seat core 7 ends, makes medicinal liquid enter in the cavity of filter; Described strainer cover 2 has venthole 8, and venthole 8 places are fixed with hydrophobic membrane 4 on the inwall of described strainer cover 2; Described venthole 8 has 4, and described strainer cover 2 cooperatively interacts and fixedlys connected with filter seat 1 and is integral, and forms a cavity between filter membrane 3, liquid feeding end 5, strainer cover 2.
Above-described precision liquid medicine filter makes by the following method: the one, and utilize mold injection to become required form filter seat, strainer cover; The 2nd, behind the injection molded, will annotate north part and be warmed to 60 degree, be incubated 12 hours, cooling; The 3rd, filter membrane is welded to ultrasonic welding machine on the relevant position of filter seat, utilize ultrasonic welding machine to be welded on the relevant position of strainer cover hydrophobic membrane; The 4th, with ultrasonic welding machine that strainer cover and filter seat is integrally welded.
Farthest lowered the resistance that big flow transfusion produces according to above-described precision liquid medicine filter, simultaneously the optional position door of filter can aerofluxus, can guarantee the needs of clinical big flow transfusion, preparation technology is simple simultaneously, the junction firmness and the stability of filter are improved, and this technology has been avoided adopting conventional bonding agent to connect the pollution problem that brings.
