Described piezometer is made by " U " plastic pipe, and it is fixed on and has on the graduated plastic plate, fills colored water in " U " shape pipe, one termination negative pressure chamber.
Described alarm is made up of music-integrating block and luminous miniature bulb, switch contacts, circuit etc., switch contacts one utmost point is fixed on the upper flap termination of negative pressure chamber, one utmost point is fixed on the plastic frame wall that is used for fixing negative pressure chamber, the relative negative pressure chamber in the two poles of the earth downwards on time, the two poles of the earth separately, when since the elastic effect of gas expansion and negative pressure chamber self under, negative pressure chamber returns to resting state makes the two poles of the earth contact, circuits for triggering, make music-integrating block send the sound, emitting bulb is shinny simultaneously, pushes negative pressure chamber once more in order to reminds people, produces negative pressure.
This utility model is provided with the adjust blood pressure bottle, makes negative pressure keep certain pressure, avoids suddenly big or suddenly small; This utility model also has the piezometer of a survey negative pressure, can predict the size of negative pressure value, and has a warning function, when negative pressure value was too small, reminds people was pushed negative pressure chamber once more, and continuous negative pressure is provided, this utility model is simple in structure, the equal molding of primary structure, cost is low, is the ideal drainage system of each hospital.
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is a principle assumption diagram of the present utility model.
Fig. 2 is an embodiment overall structure figure of the present utility model.
Fig. 3 is circuit theory diagrams of the present utility model.
Shown in the figure: 1, liquid-collecting bottle, 2, drainage tube, 3, water-sealed drainage bottle, 4, water sealing (sealing water) pipe, 5, the adjust blood pressure bottle, 6, surge pipe, 7, negative pressure chamber, 8, piezometer, 9, alarm, 10, the adjust blood pressure turn-knob, 11, check valve, 12, frame wall, 13, music-integrating block.
As shown in Figure 1, this utility model mainly is made up of liquid-collecting bottle 1, water-sealed drainage bottle 4, adjust blood pressure bottle 5, negative pressure chamber 7, piezometer 8 and connection tube, above-mentioned a few part is fixed in the plastic frame (shown in Figure 2), water-sealed drainage bottle 4 and adjust blood pressure bottle 5 are in front placed side by side, two bottles wide with liquid-collecting bottle 1, liquid-collecting bottle 1 next door is fixed in negative pressure chamber 7, there is a plastic plate its front, piezometer 8 is fixed on the plastic plate, plastic plate is carved with scale, fixedly music-integrating block, emitting bulb, on and off switch on its right side plastic plate.
The cuboid cavity that described negative pressure chamber 7 makes for elastomeric material, be corrugated all around, two mouthfuls by rigid plastics lid sealing up and down, there are three on the seal cover suitable for reading and draw joint, one joint meets of adjust blood pressure bottle 5 by connection tube and draws joint, be fixed with a check valve 11 on its connection tube, to guarantee that gas flows to negative pressure chamber 7 from adjust blood pressure bottle 5, on connection tube, also be fixed with the adjust blood pressure turn-knob 10 of a scalable vacuum magnitude, one connects piezometer 8, the other end of upper flap leads directly to atmosphere, is connected to check valve on its head, makes gas flow to air from negative pressure chamber 7.
Cover in the negative pressure chamber 7 and be fixed with an electrode, also adorn an electrode on the adjacent frame wall 12, negative pressure chamber can be used as the contact switch of alarm in the contact of resting state two electrodes, piezometer 8 is made by plastic tube by " U " type, fixing on its plastic plate has the scale numeral, charges into colored water in " U " type pipe, makes it to reach 0 scale, " U " pipe one side is connected with negative pressure chamber 7, the interior water column of " U " type pipe that connects side rises, and the opposite side water column descends, and can read the negative pressure value of generation in view of the above.
Alarm 9 is made up of electronic music integrated circuit piece 13 and bulb, is fixed on the right side with 8 same plastic plates of piezometer.Be connected with two electrodes by circuit.7 capacity are saturated when negative pressure chamber, and negative pressure disappears, and can observe from piezometer.At this moment negative pressure chamber 7 expands and raises, the contact of two electrodes, and alarm sends electronic music sound, and bulb is shinny, and prompting need be pushed negative pressure chamber's loam cake once more, makes it to be compressive state to produce negative pressure.Two electrode separation, piezometer show negative pressure value again, and bulb extinguishes, and electronics sound disappears, and negative pressure chamber can produce the 1000ml capacity from being compressed to expansion, and general every day drainage flow all less than 1000ml.
Adjust blood pressure bottle 5 is connected with water-sealed drainage bottle 3 by connection tube, and negative pressure reaches water-sealed drainage bottle 3, has two to draw joint on water-sealed drainage bottle 3 bottle caps, and another joint outer end is connected with liquid-collecting bottle.Interior termination one hard transparent plastic pipe, water-filling 3-5cm height in the bottle makes the plastics mouth of pipe by water seal, the air that assurance is discharged from liquid-collecting bottle can only be discharged from plastic tube, and in a single day drainage device when leaking gas, and ambient atmos can not enter human body (the plastics mouth of pipe is by water seal, and gas can not enter).
Water-sealed drainage bottle 3 is connected with liquid-collecting bottle 1 by connection tube, and negative pressure reaches liquid-collecting bottle 1, and another joint on 1 bottle of the liquid-collecting bottle is connected with the drainage tube 2 of human body, to carrying out continuous negative pressure suction in the human body.The gas or the liquid of drawing in the human body enter liquid-collecting bottle, enter water-sealed drainage bottle equivalent air from liquid-collecting bottle simultaneously, by connection tube until negative pressure chamber.Liquid-collecting bottle 1 can once use the back to take out from framework and change.
As the breaking alarm switch, and make negative pressure chamber be swelling state, then become the nature drainage.
