The utility model is described in further detail below in conjunction with drawings and Examples: two peristaltic pump ascites ultra-filtration therapeutic instruments mainly are made up of main frame, molecular sieve filter, pipeline and operation support.Its molecular sieve filter and pipeline are prior art, tubular fibre filter and the polyethylene artery and vein conduit of selecting for use Asia-Pacific, Ningbo purifier factory to produce, and the operation support is a prior art, is used to place instruments such as main frame, molecular sieve filter, pipeline.Its main frame is an architectural feature of the present utility model, consult shown in Figure 1, its main frame casing 5 is hexahedro solid type, the front is provided with panel 6, is provided with two peristaltic pumps-main road pump 1 and branch road pump 2 in the casing 5, connects motor transmission shaft respectively, motor is selected the miniature variable speed electric motors, particularly of outsourcing for use, connect main road pump 1 speed governing knob 10 and branch road pump 2 speed governing knobs 8 on machine governor and the panel 6 respectively by alignment circuit, servo circuit is selected in speed governing for use, to guarantee that flow is accurate; Main road pump 1 and branch road pump 2 also are connected infrared ray sensor and main road pump 1 digital frequency meter 3 and branch road pump 2 digital frequency meters 4 in the main frame casing 5 by tachometric survey circuit and control circuit, and its indicating gage can accurately show the speed revolution value of pair peristaltic pumps on panel 6.Above-mentioned speed governing, tachometric survey and control circuit are selected comparatively sophisticated prior art for use, machine governor, speed governing knob, infrared sensor, numerical frequency are taken into account electronics, electrical equipment is a prior art, buyable, and the installation site in casing 5 is random, is not subjected to restriction of the present utility model.On panel 6, also be provided with the switch 11 of main road pump 1 and the switch 7 and the total power switch 9 of branch road pump 2.
Consult Fig. 3, Fig. 4, shown in Figure 5, two peristaltic pumps-main road the pump 1 that is provided with in the main frame is identical with branch road pump 2 structures, mainly by the pump housing 15, pump head 14, main shaft 22, tachometer disc 21 4 most of formations, the pump housing 15 is provided with pipeline outlet 12, pipeline inlet 19, pump chamber 30, pump head 14 is provided with lower pressure wheel 13, shank of the key 25, inner guiding post 23, outer guiding post 24, guide pillar 18, about six roots of sensation guide pillar altogether, and speed governing screw 27, spring 26, lock pin 33, slide bar 31, spindle nose 32, lock ring 29, its pump head 14 mainly is by lock ring 29 with the connection of main shaft 22, shank of the key 25, lock pin 33, spindle nose 32 is realized, be that shank of the key 25 is milled with the wide flat groove of 5mm, spindle nose 32 is milled with the thick homalocephalus of 5mm, draw back pump head shank of the key 25 pump head 14 is inserted main shaft 22, turn clockwise lock pin 33 is imported between two lock rings 29, and depress shank of the key 25 simultaneously homalocephalus and flat groove are coincide, can make the rotation that links into an integrated entity of main shaft 22 and pump head 14 like this.The effect of lock pin 33, lock ring 29 is to make pump head 14 and main shaft 22 unlikely disengaging in rotation, main shaft axle tail 20 connects miniature variable speed electric motors, particularly, main shaft 22 is provided with bearing 28, drive pump head 14 and change rotation counterclockwise with per minute 0-75, two pinch roller 13 every Rotate 180 degree alternately push pipeline once up and down, its volume is about half of pipeline circumference internal diameter volume, with internal diameter Φ 8mm pipeline is example, main shaft whenever rotates a circle, piping flow is about 5.76ml, pump chamber 30 and pinch roller 13 gaps should be controlled between the 3-5mm, and gap low discharge more is big more, otherwise since.For producing by batch, with pump head 14 and motor gear box partial installation.Pump chamber 30 is to realize by adjustment screw 27, the spring 26 adjusted on the pump head 14 with the adjustment in pinch roller 13 gaps.Pipeline on its pump housing 15 outlet 12 should with inner guiding post 23 inboard maintaining an equal level (apart from the about 10mm in pump chamber bottom), pipeline inlet 19 should with guide pillar 23,24 symmetries (about 15mm bottom the pump chamber), pipeline is mediated.The effect of guide pillar is to prevent that the pipeline that pushes is unlikely, and guide pillar and pump chamber 30 gaps are about 0.5-1.5mm, and too small processing and assembly precision require too highly can't realize large-scale production that excessive then pipeline is deviate from easily.It is the iron plate of Φ 11-14cm that its tachometer disc 21 adopts the thick outside diameter of 1.5-3mm, evenly be drilled with the aperture of 60 Φ 1.5-3mm at distance edge 5-10mm, be light-measuring holes 17 of per 6 degree, and on tachometer disc 21, connect infrared ray sensor and digital frequency meter (60 pulses of revolution), just can form a complete speed measuring device, pump head 14 rotating speeds are carried out kinetic measurement.
Consult shown in Figure 5ly, operation principle of the present utility model: (rotating speed of setting main road pump 1 is N to patient abdominal cavity ascites under the effect of main road pump 1
1), enter the molecular sieve filter by pipeline and go out screen filter through the hollow fibre pipe flow, return then in patient's body, if (rotating speed of setting branch road pump 2 is N in branch road pump 2 unlatchings this moment
2), adjust main road pump 1 and branch road pump 2 rotating speeds, make N
1＞N
2, main road pressure P then
1＞branch road pressure P
2, relative main road, branch road is negative pressure state, and under the effect of negative pressure, harmful components such as ascites moisture and middle small-molecular weight garbage are that the molecular sieve orifice flow goes out along the hollow fibre tube wall.Because proteic molecular weight is bigger in the ascites, therefore fed back to human abdominal cavity again, promptly filter the ascites therapeutic purposes of retaining protein again thereby reach.
Using method of the present utility model: press ascites puncture operation now often, ascites is introduced conduit from left lower quadrant, with positive pressure pump is that main road pump 1 control ascites flow velocity is 150-250ml/ second, ascites during by filter under 2 effects of negative pressure pump branch road pump, make water and in, material such as micromolecule leaches, the ascites transvenous catheter after concentrating is fed back into the abdominal cavity from the upper right abdomen of patient.Overall process is the closed sterile working, and is evident in efficacy.
