Description

Technical Field

[0001] The invention relates to the field of acoustic medicine and ultrasonic transducer equipment, and in particular to an ultrasonic probe water bag water treatment device and a treatment method thereof. Background Art

[0002] With the advancement of science and technology, ultrasonic transducers, as components of ultrasonic medical equipment, are widely used in medical clinical diagnosis and treatment such as B-ultrasound examination and ultrasonic lithotripsy. At the same time, the application of ultrasound to human cells is also gradually maturing in research. Under the action of ultrasound of a specific sound intensity, the metabolic rate of human cells will increase, which can treat local diseases.

[0003] Since the impedance of the ultrasonic transducer radiation surface does not match that of the human body, the efficiency of its sound radiation entering the human body is low. Usually, the method of applying coupling agent can be used, but in order to ensure that the sound intensity radiated by the ultrasonic transducer is stable and controllable, a water bag with a constant amount of water is set in front of the ultrasonic transducer to match the impedance. The ultrasonic transducer plus the water bag at its front end are combined into the ultrasonic probe.

[0004] Human cells are very sensitive to ultrasound intensity. Too high an intensity will damage cells, while too low an intensity will have a poor therapeutic effect. Usually, ultrasound radiation can effectively treat diseases only when the intensity is just right. Therefore, it is necessary to control the intensity of the ultrasound transducer radiating into the human body and irradiating the lesion with high precision, so that the radiation intensity is kept at a reasonable setting, in order to effectively treat the disease. When the ultrasound transducer is working, the amount of water in the water bag in front of it is the key factor in maintaining a reasonable setting for the radiation intensity. At the same time, if there are bubbles in the water bag, they will greatly interfere with the sound radiation of the ultrasound probe, so the absence of bubbles in the water bag is also a guarantee of the radiation intensity.

[0005] There are relatively few overall designs for ultrasonic probe water treatment devices, including patent number CN208640753U: a nasal ultrasonic probe water bag integrated device, in which the ultrasonic transducer and the water bag are installed separately and need to be installed separately, which is different from the present invention; patent number CN102928516A: an ultrasonic probe water bag for detecting composite parts, which designs a water bag at the front end of the ultrasonic transducer and uses a water volume regulating sheet to adjust the water volume in the water bag. It is a transducer for industrial detection and has no water volume regulation in the water bag after long-term use. The present invention provides a solution for the deterioration after use, which is different from the present invention; Patent No. CN2373048Y: Ultrasound probe water bag, which designs a water bag at the front end of the B-ultrasound probe, but the transducer is separated from the water bag, and the filling and exhaust of the water bag are manually operated, and it does not explain how to fill and exhaust the water. The present invention has carried out an automated design for this; Patent No. CN209678471U: A gastroscope probe water bag cap, which invents and designs a water bag cap in front of a gastroscope, used for a gastroscope probe, and it does not explain how to ensure that there are no bubbles in the water bag. Summary of the invention

[0006] The purpose of the present invention is to provide a water treatment device and method for the water bag of an ultrasonic probe, which is exquisitely designed and can automatically fill and pump water from the water bag in the ultrasonic probe, and accurately control the amount of water filled, so that the state of the water bag is consistent when the ultrasonic probe is used, so as to meet the use requirements of the ultrasonic probe. At the same time, after the water bag is filled with water, there are no bubbles in the water, which ensures that the ultrasonic probe is not affected by bubbles and works stably.

[0018] S3. When the liquid level sensor detects that water is pumped out during the exhaust process, the sensor sends feedback to the control platform, which issues a command to stop exhausting and closes the on-off valve B to achieve the initial exhaust action.

[0024] S3. When the three-way switching valve B is switched to the upper blocking state and the lower blocking state to the side opening state, air will naturally enter the water bag of the ultrasonic probe to balance the air pressure inside and outside the water bag of the ultrasonic probe. After a certain period of stagnation, the on-off valve B will be closed to complete the water pumping action. The alarm device will issue a warning and wait for the user's subsequent instructions.

The specific steps of the water filling method are as follows:

[0048] S1: The ultrasonic probe 7 to be filled with water is placed on the operating table. The user operates on the operating screen of the control platform 1 to automatically connect the water filling and pumping device 2 to the ultrasonic probe 7. The water filling command is issued through the control platform 1.

After a certain period of stagnation, the on-off valve B26 is closed to complete the water pumping action. The alarm device 4 issues a warning that the water pumping is completed, and waits for subsequent instructions from the user.
