A thread is provided on the outer peripheral surface of the rod body and at a corresponding position of the annular airbag. A rotating ring is threadedly connected on the rod body and above the annular airbag.

DETAILED DESCRIPTION

[0023] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0024] Example

[0025] Reference Figure 1-5A probe device for continuous echocardiography monitoring includes a rod body 1, a probe block 2 is fixedly connected to the lower end of the rod body 1, a device slot 3 is provided at the lower end of the probe block 2, a damping block 4 is fixedly connected in the device slot 3, a piezoelectric chip 5 is bonded to the lower end of the damping block 4, and the lower end of the piezoelectric chip 5 extends out of the device slot 3. The damping block 4 and the piezoelectric chip 5 are both prior art and are used for ultrasonic detection. The protruding part of the lower end of the piezoelectric chip 5 is used to directly contact the human skin. A coating groove 6 is provided at the lower end of the probe block 2 and in front and behind the device slot 3. Lifting grooves 7 are provided on the inner walls of the left and right sides of the two coating grooves 6. A rectangular lifting block 8 is slidably connected in each lifting groove 7. A spring 9 is fixedly connected between the upper end surface of each lifting block 8 and the corresponding lifting groove 7. A coating roller 10 is rotatably connected between the two lifting blocks 8 located in the same coating groove 6. The coating roller 10 facilitates the movement of the probe block 2 on the surface of the human body. The coating roller 10 moves into the coating groove 6 under the action of the downward pressure. A storage chamber 11 is provided in the probe block 2 and above the two coating tanks 6. The storage chamber 11 is used to store coupling agent. A plurality of evenly arranged communication holes 12 are provided on the inner bottom wall of the storage chamber 11 and communicate with the corresponding coating tanks 6. A vertical plate 13 is fixedly connected to the upper end of the lifting block 8 and in the coating tank 6. A horizontal plate 14 is fixedly connected to the upper ends of the two vertical plates 13 in the same coating tank 6. The horizontal plate 14 is located above the coating roller 10 and rises and falls simultaneously with the corresponding coating roller 10. A plurality of discharge columns 15 corresponding to the positions of the upper communicating holes 12 are fixedly penetrated on each horizontal plate 14. The upper ends of the discharge columns 15 are sealed and slidably inserted in the corresponding communicating holes 12. A right-angle hole 16 is provided in each discharge column 15. The lower end opening of the right-angle hole 16 is provided at the lower end surface of the discharge column 15, and the upper end opening is provided at the side of the discharge column 15 away from the device slot 3. The discharge columns 15 and the right-angle holes 16 are provided to discharge the coupling agent in the storage chamber 11 into the coating tank 6. The lower end of each right-angle hole 16 is connected to a one-way valve 17, and the coupling agent can only flow from the storage chamber 11 to the coating tank 6, and the liquid cannot flow back through the right-angle hole 16, so that when the probe is cleaned, the liquid will not enter the storage chamber 11.

[0026] The height of the lower end surface of the coating roller 10 is lower than the height of the lower end surface of the piezoelectric chip 5. The vertical distance between the lower end surfaces of the coating roller 10 and the piezoelectric chip 5 is greater than the distance between the upper end opening of the right-angle hole 16 and the storage chamber 11. When the lifting block 8 is at the lowest position, the upper end opening of the right-angle hole 16 is located in the connecting hole 12. When using this probe for echocardiography, after the lower end of the probe block 2 is close to the human skin, a slight force is applied downward to make the coating roller 10 flush with the lower end surface of the piezoelectric chip 5, so that both of them are in contact with the human skin at the same time. At this time, the horizontal plate 14 also drives the corresponding discharge column 15 to move upward, so that the upper end opening of the right-angle hole 16 enters the storage chamber 11 and is connected with it, so that the coupling agent can be added.

[0027] The upper ends of the two storage chambers 11 are connected to a pressurizing tube 20, and the upper ends of the pressurizing tubes 20 are provided with a connector 26. By introducing air into the storage chamber 11 through the pressurizing tube 20, the internal air pressure can be increased, so that the coupling agent can be squeezed into the coating groove 6 through the right-angle hole 16 and fall on the coating roller 10. As the probe block 2 moves on the surface of the human skin, the coating roller 10 can evenly apply the coupling agent on the human skin, thereby ensuring the stable state of the piezoelectric chip 5 during ultrasonic detection.

[0028] The upper ends of the two reservoirs 11 are connected to a dosing tube 19, and a tube cover is provided on the upper end of the dosing tube 19 for adding coupling agent to the reservoir 11. The setting of the tube cover can ensure the sealing of the reservoir 11. Since the coupling agent is a viscous liquid, when the inside of the reservoir 11 is not pressurized, the coupling agent cannot flow into the coating tank 6 through the smaller right-angle hole 16 under the action of gravity.

[0029] Observation glasses 18 are provided at both the front and rear ends of the probe block 2 and at the position of the reservoir chamber 11, so as to facilitate observation of the amount of coupling agent in the reservoir chamber 11 and thus facilitate replenishment of the coupling agent.

[0030] A fixed ring plate 21 is fixedly sleeved on the rod body 1, and an annular airbag 22 is coaxially fixedly connected to the upper end of the fixed ring plate 21. A thread 23 is provided on the outer circumference of the rod body 1 and at the corresponding position of the annular airbag 22. A rotating ring 24 is threadedly connected on the rod body 1 and above the annular airbag 22. The lower end of the annular airbag 22 is connected to two air pipes 25, and the two air pipes 25 are connected to the pressurized pipe 20 through a connector 26. The outer circumference of the rotating ring 24 is provided with anti-slip patterns to facilitate the rotation of the fixed ring plate 21. Before the acoustic monitoring, it is only necessary to rotate the fixed ring plate 21 to compress the annular airbag 22, and the gas in the annular airbag 22 can be pressed into the corresponding agent storage chamber 11 through the air pipe 25 and the pressure pipe 20, so that the internal pressure is increased. Then, when the ultrasonic monitoring is performed, after the probe block 2 is pressed down, the coupling agent can be automatically added to the coating tank 6 so as to evenly apply the coupling agent. It is simple and convenient to use. When the coupling agent cannot be automatically discharged, the rotating ring 24 is rotated again to compress the annular airbag 22. When replenishing the internal gas of the annular airbag 22, it is only necessary to open the agent pipe 19 or disconnect the air pipe 25 from the pressure pipe 20.

[0031] A gripping plate 27 is fixedly connected between the two sides of the upper end of the probe block 2 and the fixed ring plate 21, which is convenient for the user to grip and use the probe. A connecting wire 28 is connected to the upper end of the rod body 1. The end of the connecting wire 28 away from the rod body 1 is connected to the ultrasonic display device for power supply and signal connection. The ultrasonic display device is a prior art and will not be explained here.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
