The working principle is as follows: when a patient paints couplant, a doctor needs to hold the probe 2 by hand, continuously extrudes the air bag 5 on the surface of the probe 2 by fingers in the process of holding the probe 2 by hand, so that the air bag 5 contracts, the air bag 5 sucks air into the air bag 5 through the air inlet hole 51 arranged at the upper end, the air bag 5 extrudes the air stored in the air bag 5 to the control valve 4 fixedly connected with the air bag 5, in the process of conveying the air, the air blows the sheet 43 arranged between the air inlet part 41 and the air outlet part 42, so that the sheet 43 is attached to the port of the air outlet part 42 arranged at one end, close to one end of the air bag 5, in the control valve 4, the air flows into the air pipe 6 at the other end of the control valve 4 through the through hole 421 arranged in the air outlet part 42, so as to convey the air into the closed pressurizing cabin 3 through the air pipe 6, the cabin 3 is continuously pressurized by introducing the air, so that the cabin is continuously pressurized air, and then the couplant contained in the pressurizing cabin 3 is extruded to flow into the infusion pipe 7 communicated with the pressurizing cabin 3, thereby make the couplant flow in smear 23 inside through the transportation of transfer line 7 to being equipped with a plurality of liquid holes 21 through smearing 23 surface, the rear end is equipped with in probe 2 and goes out the extrusion storehouse 22 of liquid hole 21 intercommunication, makes the couplant extrude through extruding storehouse 22 and extruding storehouse 22 surface and being equipped with a plurality of liquid holes 21.
When the patient finishes smearing the couplant, the doctor stops extruding the air bag 5, one end of the air inlet 41 of the control valve 4 is recovered to normal air pressure due to no air input, one end of the air outlet 42 of the control valve 4 is subjected to pressure release in the pressurizing bin 3, so that the sheet 43 is attached to the port of the air inlet 41 due to the pressure release, and as the air inlet 41 is not provided with the through hole 421, air cannot be discharged, so that the air pressure in the pressurizing bin 3 is relatively stable, residual couplant in the extruding bin 22 and in the infusion tube 7 cannot flow out, and the doctor performs next color Doppler ultrasound detection on the patient;
after the patient completes the detection, the couplant inside the extrusion chamber 22 and the infusion tube 7 needs to flow back to the inside of the pressurization chamber 3, the poking piece 44 fixedly connected with the sheet 43 is pushed towards the direction of the air outlet piece 42, so that the sheet 43 is separated from the port of the air inlet piece 41, a gap is generated between the sheet 43 and the port of the air inlet piece 41, at this time, the gas inside the pressurization chamber 3 and the air tube 6 can flow out of the pressurization chamber 3 and the air tube 6 through the gap generated when the sheet 43 is separated from the air inlet piece 41, the pressure in the pressurization chamber 3 is released and is recovered to the normal air pressure, and the couplant inside the probe 2 and the infusion tube 7 can automatically flow into the pressurization chamber 3 due to the self weight because the probe 2 and the infusion tube 7 are positioned at the upper end of the pressurization chamber 3.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
