[0030] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0031] like Figures 1-12 As shown, the ultrasonic probe with heating function includes a housing 1 and a probe body 3; it also includes: Bottom sleeve 2, the bottom sleeve 2 is fixedly installed at the opening at the bottom of the outer shell 1, and the bottom surface of the bottom sleeve 2 is evenly provided with a plurality of discharge micro holes 201, and the discharge micro holes 201 are connected to the annular inner cavity 202 provided inside the bottom sleeve 2. The feeding mechanism includes a storage box 10 for storing coupling agent and an air injection component for pressurizing the inside of the top side of the storage box 10. The bottom side of the storage box 10 is connected to the annular inner cavity 202 through a feeding tube 203, and a heating element 1001 is provided on the inner wall of the storage box 10. The air extraction assembly 12 has its air inlet located inside the top side of the storage box 10.

[0032] Before the ultrasound examination, gas is injected into the top of the storage box 10 via the gas injection component to increase the air pressure above the coupling agent liquid surface inside the storage box 10. This air pressure propels the coupling agent through the delivery tube 203 into the annular inner cavity 202, and then it flows out from several outlet micro-holes 201 on the bottom surface of the base sleeve 2. The operator holds the outer shell 1 and moves it to the area to be examined on the patient, ensuring the bottom surface of the base sleeve 2 is against the patient's skin to apply the coupling agent. During this application process, the operator's hands do not come into contact with the coupling agent, and there is no need to put on or remove gloves, providing convenience for the application.

[0033] The coupling agent is stored in the storage box 10. The heating element 1001 on the wall of the storage box 10 heats the coupling agent in the storage box 10, so that the temperature of the coupling agent applied to the patient site is the same as the body temperature, avoiding the temperature being too low and causing discomfort to the patient.

[0034] Among them, the heating element 1001 is preferably a constant temperature heating element 1001, such as a PTC constant temperature heating element.

[0035] After application, the vacuum assembly 12 evacuates the top side of the storage box 10 to reduce the air pressure inside the top side of the storage box 10. Under the action of external air pressure (the annular inner cavity 202 is connected to the outside air through the discharge micro-hole 201), the coupling agent in the annular inner cavity 202 and the feeding capillary 203 flows back into the storage box 10, preventing the coupling agent from remaining in the annular inner cavity 202 and the feeding capillary 203. Without the heating element 1001 to heat and keep warm, this part of the low-temperature coupling agent will come into contact with the patient during the next use, causing discomfort to the patient.

[0036] like Figure 2 , Figure 6 as well as Figure 7 As shown, the air injection assembly includes an air injection pump 11 disposed above the storage box 10. The air injection pump 11 is fixedly installed inside the outer casing 1. A first electrically controlled valve 1102 is installed at the air outlet of the air injection pump 11, and the bottom port of the first electrically controlled valve 1102 is connected to the top of the storage box 10. An air inlet pipe 1101 is installed at the air inlet of the air injection pump 11. The air inlet pipe 1101 extends to the shell wall of the outer casing 1, and the end of the air inlet pipe 1101 away from the air injection pump 11 is connected to the outside of the outer casing 1.

[0037] When pressurizing the inside of the top side of the storage box 10, the first electrically controlled valve 1102 is opened, and the air pump 11 draws in external air through the air inlet pipe 1101 and delivers it, so that the air is input into the inside of the top side of the storage box 10 through the first electrically controlled valve 1102 to achieve pressurization.

[0038] like Figure 7As shown, a third electrically controlled valve 1901 is installed on the top of the storage box 10. The third electrically controlled valve 1901 is connected to a vent pipe 19, which extends to the shell wall of the outer casing 1. The end of the vent pipe 19 away from the third electrically controlled valve is connected to the outside of the outer casing 1. A feeding pipe 13 is connected to one side of the bottom of the storage box 10. A second electrically controlled valve 1301 is provided between the feeding pipe 13 and the storage box 10. The feeding pipe 13, the first connecting line 17, and the second connecting line 18 are fixed together, extending from the top of the outer casing 1, and all three are fixed to the top position of the outer casing 1. The feeding pipe 13 is a flexible hose and is connected to an external feeding device.

[0039] A liquid level sensor is installed inside the storage box 10. Both the feeding device and the liquid level sensor are connected to an external control module for control.

[0040] The feeding device uses a container for storing coupling agent, and a delivery pump is installed inside the container, which is connected to the feeding pipe 13.

[0041] A solenoid valve is installed at the connection between the feeding tube 203 and the storage box 10 to control its opening and closing.

[0042] A liquid level sensor monitors the liquid level in real time, and the signal is transmitted to the control module via the second connection line 18. The module determines the liquid level in the storage box 10. When the liquid level is below the set minimum value, the control module closes the solenoid valve at the feeding tube 203 and the first electrically controlled valve 1102, while opening the third electrically controlled valve 1901 and the second electrically controlled valve 1301. The feeding pump of the feeding device then feeds coupling agent into the replenishment pipe 13, which enters the storage box 10. Simultaneously, the liquid level sensor monitors the internal liquid level in real time. Once the set maximum liquid level is reached (the maximum liquid level is below the height of the top of the vertical pipe 1202), the pump, the third electrically controlled valve 1901, and the second electrically controlled valve 1301 are automatically shut off. When applying coupling agent to the patient again subsequently, the solenoid valve and the first electrically controlled valve 1102 are opened.

[0043] During the above-mentioned feeding process, the third electrically controlled valve 1901 is opened so that the top of the storage box 10 is connected to the outside air through the vent pipe 19, so that atmospheric pressure is maintained above the liquid surface at the top of the storage box 10.

[0044] like Figure 2 As shown, the probe body 3 is disposed inside the housing 1. The bottom of the probe body 3 is provided with a side shoulder 301, and the outer peripheral wall of the bottom of the probe body 3 is connected to the inner wall of the bottom sleeve 2 with a clearance fit. A first side block 302 is fixed on one side of the probe body 3. An electric push rod 4 is fixedly installed inside the housing 1, and the output shaft end of the electric push rod 4 is fixed to the top of the first side block 302.

[0045] Through the above design, the electric push rod 4 extends and retracts, driving the probe body 3 to move. The probe body 3 slides against the base sleeve 2, allowing the probe body 3 to extend or retract from the bottom of the outer casing 1. When applying coupling gel to the patient, the probe body 3 retracts into the outer casing 1, as shown above. Figures 2-3 As shown, this prevents the probe body 3 from interfering with the application of the coupling agent. After the coupling agent is applied, the probe body 3 extends from the bottom of the outer shell 1, allowing the probe body 3 to come into contact with the patient.

[0046] like Figures 2-3 As shown, an inflatable sealing ring 9 is fixedly installed at the inner top of the bottom sleeve 2. The inflatable sealing ring 9 is connected to two inflatable parts 7 through a connecting air pipe 8 set inside the wall of the outer shell 1. A first stop 5 and a second stop 6 are fixedly installed on the inner wall of one side of the outer shell 1. The two inflatable parts 7 are respectively installed on the first stop 5 and the second stop 6. The first stop 5 is located below the first side block 302, and the second stop 6 is located above the side shoulder 301 of the probe body 3.

[0047] like Figures 4-5 As shown, the inflation part 7 includes a first cylinder 701; a first piston 702 is connected inside the first cylinder 701, and the first piston 702 is elastically connected to the inner end face of the first cylinder 701 through a first spring 704. The inner wall of the first cylinder 701 and one side of the first piston 702 form a cavity, and the cavity is connected to the inflation sealing ring 9 through a connecting air pipe 8. A pressure-bearing column 703 is fixed to the first piston 702. A through hole is opened at one end of the first cylinder 701, and the pressure-bearing column 703 passes through the through hole and extends to the outside of the first cylinder 701. The first cylinders 701 of the two inflation parts 7 are respectively fixed to the first stop 5 and the second stop 6. The end of the pressure-bearing column 703 of the inflation part 7 located on the first stop 5 is away from the first piston 702 and faces the first side block 302. The end of the pressure-bearing column 703 of the inflation part 7 located on the second stop 6 is away from the first piston 702 and faces the side shoulder 301.

[0048] like Figure 2 As shown, when the probe body 3 is retracted into the outer casing 1, its side shoulder 301 is attached to the bottom surface of the second stop 6. At the same time, the side shoulder 301 presses on the pressure column 703 of the inflation part 7 on the second stop 6, compressing the cavity of the inflation part 7 and compressing the first spring 704, so that the gas in the cavity of the inflation part 7 enters the inflation sealing ring 9 through the connecting air pipe 8, causing the inflation sealing ring 9 to expand and ensuring the sealing between the probe body 3 and the bottom sleeve 2.

[0049] When the probe body 3 extends from the housing 1, the side shoulder 301 separates from the second stop 6, and the pressure on the pressure column 703 of the inflation part 7 on the second stop 6 is released. The first piston 702 and the pressure column 703 are moved by the elastic force of the first spring 704, causing the cavity in the inflation part 7 to increase in volume. Gas is drawn from the inflation sealing ring 9 through the connecting air pipe 8, causing it to contract, thus reducing friction and wear between the probe body 3 and the inflation sealing ring 9 during subsequent movement. The probe body 3 continues to move downwards, causing the first side block 302 to move towards the first stop 5. As the first side block 302 approaches and contacts the end of the pressure column 703 of the inflation part 7 on the first stop seat 5, until the first side block 302 contacts the first stop seat 5, the first side block 302 presses down on the pressure column 703. The first piston 702 below the pressure column 703 moves downward together, compressing the first spring 704 and compressing the cavity of the inflation part 7. This causes the gas in the cavity to be input into the inflation sealing ring 9 through the connecting air pipe 8, causing the inflation sealing ring 9 to expand. This ensures the seal between the probe body 3 and the bottom sleeve 2 when the probe body 3 is extended from the outer shell 1.

[0050] As the probe body 3 returns to the outer casing 1, the first side block 302 moves upward, separating from the inflation part 7 on the first stop 5. The first spring 704 in the inflation part 7 drives the first piston 702 and the pressure column 703 to move upward, causing its cavity to draw gas from the inflation sealing ring 9 through the connecting air pipe 8. The inflation sealing ring 9 contracts, reducing the friction and wear between the probe body 3 and the inflation sealing ring 9 as it moves upward. The probe body 3 continues to move upward, and the side shoulder 301 moves closer to the second stop 6. 301 contacts the pressure column 703 of the inflation part 7 on the second stop seat 6 until the side shoulder 301 is in contact with the second stop seat 6. The side shoulder 301 pushes the pressure column 703, and the pressure column 703 drives the first piston 702 to move together, compressing the first spring 704 and the cavity of the inflation part 7, so that the gas in the cavity is input to the inflation sealing ring 9 through the connecting air pipe 8, causing the inflation sealing ring 9 to expand, so as to ensure the seal between the probe body 3 and the bottom sleeve 2 when the probe body 3 is retracted into the outer shell 1.

[0051] With the above design, when the probe body 3 is retracted into the housing 1 or extended out of the housing 1, the inflatable sealing ring 9 is inflated to ensure the sealing effect; while when the probe body 3 is moving and the pressure column 703 is not pushed, the inflatable sealing ring 9 is in a contracted state to reduce wear during movement.

[0052] like Figure 6 and Figure 8As shown, the suction assembly 12 includes a second cylindrical body 1201 fixed inside the outer shell 1; a movable disc 1203 is disposed inside the second cylindrical body 1201, a rubber sleeve 1204 is fixedly sleeved on the movable disc 1203, and the outer ring of the rubber sleeve 1204 is connected to the inner wall of the second cylindrical body 1201; a retaining ring 1206 is disposed below the movable disc 1203, and the retaining ring 1206 is fixed inside the second cylindrical body 1201; a sleeve 1207 is fixedly installed at the bottom of the movable disc 1203, a magnetic block 1208 is slidably installed inside the sleeve 1207, and the magnetic block 1208 is magnetically connected to the movable disc 1203; a square post 1209 is fixed at the bottom of the magnetic block 1208. The square column 1209 is slidably sleeved with a square groove formed at the bottom of the sleeve 1207. A second spring 1210 is sleeved on the square column 1209. The magnetic block 1208 is elastically connected to the sleeve 1207 through the second spring 1210. A connecting rod 1205 is fixed to the bottom end of the square column 1209, and the connecting rod 1205 passes through a hole formed at the bottom of the second cylinder 1201. A second side block 303 is fixed to one side of the probe body 3. The bottom end of the connecting rod 1205 is fixed to the second side block 303. A vertical tube 1202 is fixedly connected to the top of the second cylinder 1201. The vertical tube 1202 passes through the bottom of the storage box 10, and the top end of the vertical tube 1202 extends to the inside of the top side of the storage box 10. The vertical tube 1202 and the bottom of the storage box 10 are seamlessly welded together.

[0053] After applying the coupling agent, the probe body 3 moves downward and extends from the bottom of the outer shell 1. The probe body 3 drives the connecting rod 1205 to move downward through the second side block 303. The connecting rod 1205 drives the movable disc 1203 and the rubber sleeve 1204 to move downward, so that the second cylinder 1201 draws the inside of the top side of the storage box 10 through the vertical pipe 1202 to reduce the air pressure inside the top side of the storage box 10, so that the storage box 10 draws back the coupling agent in the annular inner cavity 202 and the feeding thin tube 203.

[0056] like Figure 6 , Figure 9 as well as Figure 10 As shown, the translation mechanism 14 includes a slide rail 1405 fixedly installed on the inner wall of the outer casing 1. A slide block 1404 is slidably installed on the slide rail 1405. A fixing strip 1406 is fixed to one end of the slide rail 1405.

The first connecting line 17 is wound around the two guide posts 1402 and the turntable 1401.

[0058] With the probe body 3 retracted into the outer casing 1, as follows Figure 9As shown, there is a certain distance between the push bar 16 and the movable seat 1501. When the drive probe body 3 moves downward, in addition to driving the suction assembly 12 to suck the material inside the top side of the storage box 10, the probe body 3 also pulls the first connecting line 17. The first connecting line 17 pushes the turntable 1401 to move. The turntable 1401 drives the slide 1404, the connecting seat 1408, the vertical rod 1403 and the push bar 16 to move together. During the movement, the slide rail 1405 and the slide 1404 provide sliding guidance until the push bar 16 contacts the movable seat 1501. After the push bar 16 contacts the movable seat 1501, the movable disc 1203 in the suction assembly 12 just contacts the retaining ring 1206. As the probe body 3 continues to move downwards, the connecting rod 1205 continues to move downwards with the probe body 3. The connecting rod 1205 drives the square column 1209 and the magnetic block 1208 to move together, compressing the second spring 1210. The magnetic block 1208 separates from the movable disc 1203. During this process, the movable disc 1203 cannot continue to move downwards, causing the vertical tube 1202 to stop suction. Meanwhile, the rotating part of the translation mechanism 14... The disc 1401, slide 1404, connecting seat 1408, and vertical rod 1403 continue to move, driving push bar 16 to push movable seat 1501. Movable seat 1501 drives trapezoidal block 1505 to move, and the movement of movable seat 1501 is guided by the sliding between guide rod 1502 and guide sleeve 1503, while compressing fourth spring 1504. Trapezoidal block 1505 squeezes the wedge-shaped surface at the top of lifting column 1506 through inclined groove wall, causing lifting column 1506 to drive plug 1507 to move downward and block the top of vertical tube 1202.

[0059] When the coupling agent needs to be applied, the probe body 3 is retracted into the outer shell 1. The translation mechanism 14 is reset by the elastic force of the third spring 1407, causing the push bar 16 to separate from the movable seat 1501. The movable seat 1501 is reset by the elastic force of the fourth spring 1504. The lifting column 1506 is no longer squeezed by the inclined groove of the trapezoidal block 1505. The lifting column 1506 is reset by the elastic force of the fifth spring 1508, causing the plug 1507 to separate from the top of the vertical tube 1202. The movable disc 1203 and the connecting rod 1205 are reset by the elastic force of the second spring 1210 and the magnetic force between the magnetic block 1208 and the movable disc 1203. Then the connecting rod 1205 moves upward with the probe body 3, driving the movable disc 1203 and the rubber sleeve 1204 to reset.

[0060] Through the above design, the top end of the vertical tube 1202 is automatically sealed and protected without applying coupling agent, preventing coupling agent from entering the top end of the vertical tube 1202.

[0061] An operation panel is provided on the outside of the housing 1 for manual operation. The electrical components on the housing 1 (except for the probe body 3) are connected to the external control module and power supply through the second connection line 18 for power supply and control.

The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
