Abstract
The utility model relates to a disposable liquor precise filter device for intravenous transfusion, comprising a liquid inlet and a liquid outlet. The utility model is characterized in that the integral structure is composed of a left cap, a right cap and a middle piece; the left cap and the right cap are symmetrically arranged on the left and the right two sides of the middle piece, and form the closed structure with the middle piece together; the liquid inlet and the liquid outlet are respectively arranged at the upper part and the lower part of the middle piece; the two symmetric sides of the middle part of the middle piece are provided with a left filter membrane and a right filter membrane; the left cap and the left filter membrane, and the right cap and the right filter membrane respectively form a physic liquor cavity; the left filter membrane and the middle piece, and the middle piece and the right filter membrane respectively form a filter cavity; the liquid inlet is communicated with the two physic liquor cavities, and the liquid outlet is communicated with the two filter cavities. The utility model adopts the multi-cavity design, is provided with a double filter membrane, increases the filtering area under the condition of not increasing the size of the filter, improves the filtering efficiency, effectively ensures the flowing of the physic liquor, and improves the safety of the transfusion.
Description
Technical field
This utility model relates to a kind ofly imports the intravital apparatus of people with medium, particularly a kind of single intravenous infusion precision liquid medicine filter.
Background technology
In the prior art, application number is 01200844.3, publication number is that 2461571 Chinese patent application discloses the patent documentation that a kind of name is called " transfusion accurate filter ", it is by loam cake, go to the bottom and the filter membrane composition, loam cake one end is extended with the feed liquor mouth of pipe, the end of going to the bottom is extended with the fluid mouth of pipe, loam cake and go to the bottom sealed junction integrator and between form the space of ccontaining medicinal liquid, the feed liquor mouth of pipe and the fluid mouth of pipe two ends that are placed in, described filter membrane is folded in loam cake obliquely and goes to the bottom joint, and the space of ccontaining medicinal liquid is divided into last liquid storage chamber that is communicated with the feed liquor mouth of pipe and the following liquid storage chamber that is communicated with the fluid mouth of pipe.Its defective is that the effective filtration area of this filter is little, along with increasing of the solid particle that is blocked, makes filter efficiency more and more lower, thereby has prolonged the time of transfusion greatly, even can delay patient's treatment opportunity; And this filter aerofluxus is not smooth, influence transfusion safety.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and the single intravenous infusion precision liquid medicine filter of a kind of filtering accuracy height, filter efficiency height, transfusion safety is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme.This utility model is the single intravenous infusion precision liquid medicine filter, comprise inlet and liquid outlet, it is characterized in that, its overall structure is covered by a left side, You Gai and middle sheet constitute, the left and right sides of sheet during Zuo Gai and right lid symmetry are located at, constitute closed structure with middle sheet, the upper and lower of sheet during described inlet and liquid outlet are located at respectively, the middle part lateral symmetry of middle sheet is provided with left filter membrane and right filter membrane, between described Zuo Gai and the left filter membrane, respectively form 1 medicinal liquid cavity between You Gai and the right filter membrane, between left side filter membrane and the middle sheet, respectively form 1 filter chamber between middle sheet and the right filter membrane, inlet is communicated with 2 medicinal liquid cavities, and liquid outlet is communicated with 2 filter chambers.During use, medicinal liquid enters 2 medicinal liquid cavities from inlet, filters the back through left and right sides filter membrane and arrives filter chamber, then from liquid outlet output, thereby finishes whole filter process.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of single intravenous infusion precision liquid medicine filter is characterized in, covers on Zuo Gai and the right side and all is provided with steam vent, and described steam vent is communicated with medicinal liquid cavity, is provided with hydrophobic membrane in steam vent.Like this, air remaining in the medicinal liquid is discharged, further guarantee transfusion safety.Hydrophobic membrane described in the utility model is meant the filter membrane of permeable watertight.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of single intravenous infusion precision liquid medicine filter is characterized in, described steam vent is located at the upper and lower of Zuo Gai and right lid respectively, is to be symmetrical arranged.Like this, no matter how this utility model is placed, all can realize unobstructed aerofluxus.
Compared with prior art, the utlity model has following advantage: this utility model adopts the multi-cavity design, and is provided with two filter membranes, under the prerequisite that does not increase filter size, increased filter area greatly, improve filter efficiency, effectively guaranteed medicinal liquid flow, improved the safety of transfusion.Shell of the present utility model and internal layer filter membrane all adopt ultrasonic bonding, and it is meticulous that it adds technology, and firm welding does not have the phenomenon of leakage extremely.
