Description
Technical field
This utility model belongs in the mode of subcutaneous injection, intravenous injection or intramuscular injection introduces the filter assemblies of intravital apparatus with medium, is specifically related to a kind of precision liquid medicine filter that is used to infuse.
Background technology
Transfusion is the large bolus injection liquid that is splashed into human body by vein, and it directly enters the blood circulation of human body, is the important means of disease preventing and treating.Typical infusion process is that the medicinal liquid in the infusion bottle enters the human body passages through which vital energy circulates behind horse Venturi tube, control folder and liquid medicine filter.The effect of liquid medicine filter is pollutant and the air admission human body such as microgranule that prevents in the medicinal liquid.
Mainly there is following problem in the liquid medicine filter of prior art: 1) go out sap cavity and accumulate bubble easily, as can not in time discharging, may enter in patient's body, cause malpractice; 2) occur the ventilative film leakage fault that blocks water easily,, may cause pathogenic bacteria to invade transfusion system, infect the patient as can not in time finding or get rid of; In addition, the ventilative film leakage probability height that blocks water also causes scrapping of transfusion device and liquid waste; 3) be not easy to carry out the secondary aerofluxus, can cause trapped gas in the system, the rate of filtration is slowed down, and can't infuse.
Notification number is that the Chinese patent of CN2549986Y discloses a kind of transfusion device liquid medicine filter, contain loam cake, lower cover, loam cake, cover and have liquid inlet and outlet down, loam cake, lower cover all have inner chamber, between loam cake and lower cover, filter membrane is housed, on the lower cover contact surface that contacts with filter membrane, is provided with the muscle that supports filter membrane, it is characterized in that: described muscle is a plurality of arc pieces of dispersing arrangement, and the arc piece surrounds delivery hole.Its weak point is: the muscle of support filter membrane and the contact area of medicinal liquid are bigger, have increased bubble in this viscid possibility.
The content of utility model
The problem that this utility model exists at prior art, a kind of precision liquid medicine filter is provided, adopt short circle muscle structure, going out sap cavity is provided with minimizing bubbles such as collecting tank and retains, the film lengthening of blocking water of will breathing freely, this utility model is put at any angle in any position does not influence the secondary aerofluxus, has solved the problems of the prior art.
This utility model is concrete to adopt following technical scheme to realize:
A kind of precision liquid medicine filter comprises upper casing 1, lower casing 2, and a plurality of steam vents 11 are arranged on the upper casing 1, and inlet 3, liquid outlet 4 are arranged on the lower casing 2; Be provided with liquid medicine filtering membrane 5 between upper casing 1 and the lower casing 2, liquid medicine filtering membrane 5 is divided into the inner chamber that upper and lower shell 1,2 forms admission chamber 6 and goes out sap cavity 7, admission chamber 6 and go out sap cavity 7 and be connected with inlet 4, liquid outlet 4 respectively, it is characterized in that, on lower casing 2 contact surfaces that contact with liquid medicine filtering membrane 5, be provided with the short circle muscle 8 that supports liquid medicine filtering membrane 5, the trapezoidal protrusion that described short circle muscle 8 is, its side is set to smooth curve.
The described root that goes out sap cavity 7 sidewalls and junction, bottom surface and short circle muscle 8 is streamlined fillet; Describedly go out sap cavity 7 bottoms and also be provided with collecting tank 12;
The two-layer ventilative film 9,10 that blocks water is set on the described upper casing 1 to be covered on the steam vent 11; The length of the ventilative film 9 that blocks water of ground floor is greater than the ventilative film 10 that blocks water of the second layer.
The beneficial effects of the utility model are:
1) contact area of the short circle muscle structure of this utility model employing and medicinal liquid is little, has reduced the viscid probability of bubble; Deflated space is big, makes that aerofluxus is more smooth and easy, exhaust velocity is fast, and no bubble retains;
2) this utility model also is provided with collecting tank, has increased the volume that sap cavity, further is, supply and exhaust provides buffering, has avoided the too urgent and gas disturbance that causes of feed liquor;
3) of the present utility modelly go out the sap cavity turning, short circle muscle bottom is set to fairshaped fillet smooth transition, reduced bubble and gone out the viscous of sap cavity;
4) in the liquid medicine filter course of processing, easily the ventilative film that blocks water is produced damage, this utility model is provided with the two-layer ventilative film that blocks water and has reduced the ventilative membrane damage probability that blocks water, and has increased safety;
5) the ventilative film that blocks water of the present utility model is longer, make liquid medicine filter no matter at any angle, any position places, and do not influence the secondary aerofluxus;
6) greater than 90%, and this index of prior art is greater than 80% to liquid medicine filtering membrane of the present utility model to the rate that leaches of nominal diameter particle.
