Abstract
The utility model relates to the technical field of biomedicine, in particular to a precise liquid medicine filter, which comprises an upper housing, a bottom housing, a liquid medicine filter membrane and air filter membranes, and is characterized in that two air discharge holes are arranged on the upper housing, and are respectively with one air filter membrane in a hot welding way, the liquid medicine filter membranes are arranged in the bottom housing, and the upper housing is connected with the bottom housing in an ultrasonic welding way. Compared with the prior art, the precise liquid medicine filter has the advantages that insoluble particles of 0.22-5mum in the liquid medicine can be effectively filtered, air bubbles generated during the transfusion process can be discharged, and the pressure resistance property is high; the cost is low, the operation is convenient, the safety is high, and the effectiveness is good; the ultrasonic process is adopted, so that the automatic mechanical production is realized; the insoluble particles in the liquid medicine, which are harmful to a human body, can be filtered, and the air bubbles generated during the transfusion process can be discharged; and the transfusion with large flow quantity can be realized, and the transfusion with small flow quantity can be realized with pressure transfusion equipment, so the precise control to the transfusion flow quantity can be realized.
Description
Technical field
This utility model relates to the biological medicine technology field, specifically a kind of precision liquid medicine filter.
Background technology
Venous transfusion and intramuscular injection are still the most quick, the valid approach of clinical treating disease, but because infusion solutions is particles contained more, add that the contained insoluble substance of medicinal liquid is quick to this, effectively treatment means brings some sorry, long-term, the harm of hiding that to be transfusion particle bring health safety this, this is extensively confirmed by current medical science.Along with the raising of people's living substance, spiritual life level, people pay attention to the health and safety of life more, recognize that gradually transfusion particle endangers human body.Because the minimum blood capillary of adult is about 6 μ m～8 μ m, the then thinner 2 μ m～3 μ m that are about of child, in case big microgranule enters human body with transfusion, circulate at body, finally cause angiemphraxis, can cause a series of diseases, some be significantly, outbreak in a short time, more secular, hide.And clinical use mostly can only filtering 20 μ m microgranule, the factor that can filtering 2 μ m～5 μ m microgranules be confined to technology and cost that really comes into operation is very few.
Usually have air to produce in clinical transfusion process herb liquid, on the wall of the bubble that has attached to infusion tube, what have then enters human body with medicinal liquid, and big bubble carries out human body through being circulated to pulmonary, can cause air embolism, causes patient's death by suffocation.Therefore the bubble of infusing seriously jeopardizes patient's life security, thus need during clinical transfusion a kind of can deflated medical filtration device.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can deaeration and filter the liquid medicine filter of small particulate matter.
In order to achieve the above object, this utility model has designed a kind of precision liquid medicine filter, comprise upper casing, drain pan, liquid medicine filtering membrane and air filtration film, it is characterized in that: upper casing is provided with two steam vents, two steam vents adopt thermal weld respectively to connect an air filtration film, liquid medicine filtering membrane places in the drain pan, and upper casing adopts ultrasonic bonding to connect drain pan.
The right-hand member of described upper casing is provided with three equally distributed discharge orifices.
Described drain pan is provided with inlet and liquid outlet.
This utility model is compared with prior art, but the air bubble that the particulate matter of 0.22 μ m～5 μ m, discharge produce in infusion process in the effective filter medicinal liquid, have high resistance to pressure, but gravity is infused or cooperate the pressure fluid delivery apparatus to infuse, and also can adopt the usefulness of injection filtration; Cost is low, easy to operate, safe, effectiveness is good, adopt ultrasonic technology, can realize automated machine production, reach filtration to particulate matter harmful in the medicinal liquid, be used for discharging the air that produces in infusion process, the flow infusion also can cooperate the pressure fluid delivery apparatus to use greatly, realize low discharge, infusion flow is carried out precision control.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is upper casing; 2 is drain pan; 3 are the air filtration film; 4 is liquid medicine filtering membrane; 5 is steam vent; 6 is the discharge orifice; 7 is inlet; 8 is liquid outlet.
The specific embodiment
Now in conjunction with the accompanying drawings this utility model is described further.
As shown in Figure 1, this utility model comprises upper casing 1, drain pan 2, liquid medicine filtering membrane 3 and air filtration film 4.Upper casing 1 is provided with 5, two steam vents of two steam vents 5 and adopts thermal weld respectively to connect an air filtration film 3, and liquid medicine filtering membrane 4 places in the drain pan 2, and upper casing 1 adopts ultrasonic bonding to connect drain pan 2; The right-hand member of upper casing 1 is provided with three equally distributed discharge orifices 6, and drain pan 2 is provided with inlet 7 and liquid outlet 8.
When this utility model uses, medicinal liquid enters sap cavity from the inlet 7 of drain pan 2 discharge orifice 6 by upper casing 1, if air is arranged in the medicinal liquid can discharge through two steam vents 5 by air filtration film 3, medicinal liquid is by liquid medicine filtering membrane 4 then, medicinal liquid flows out from liquid outlet 8 after liquid medicine filtering membrane 4 filters, and reaches the filtration to medicinal liquid.
This utility model has steam vent 5, and the air filtration film 3 on the steam vent 5 has the characteristics of permeable watertight, can discharge the air that produces automatically when clinical use in infusion process; Liquid medicine filtering membrane 4 adopts poly (ether sulfone) films, i.e. PES film, and this material has the following advantages: percent opening height, fluid flow height; 0.22 μ m～5 μ m, filtering accuracy height, good filtration effect can be accomplished in the aperture; Have extremely strong chemical stability, acidproof, alkaline-resisting; Drug adsorption is low; Adopt the phase inversion molding, itself does not come off material, and clinical transfusion does not have the risk of self-pollution.
