To prevent overheating of the ultrasound probe and protect surrounding healthy tissue, water treatment systems are often equipped with water cooling devices. Water is also often used as a conductive medium for ultrasound during treatment. Degassed water is typically used as a coupling agent between the human body and the ultrasound generator to prevent ultrasound attenuation in air and interference with the treatment.

[0003] The existing water cooling device generally has a fixed water tank that stores medium water. However, the water tank is large in size, it is inconvenient to change the water, and it is difficult to clean the inside.

In addition, the existing water cooling device cannot accurately detect the status of the water bag and the medium, and cannot guarantee the safety and treatment effect of the treatment. During the actual treatment process, due to the material, water quality, structural installation, air pressure, air humidity and other reasons of the water bag, bubbles are easily attached to the surface of the water bag, which will cause the sound power to attenuate during the ultrasonic emission process, and the oxygen content of the medium water will lead to inaccurate detection results due to various reasons.

[0024] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] The structure of the water treatment device of the water bag probe of the utility model is as follows Figure 1 As shown, it includes a refrigeration unit 2, a degassing unit 3 and a water tank 4.

[0026] Specifically, the water bag probe's water bag 1 is connected to the refrigeration unit 2 and the degassing unit 3 via pipelines, forming the internal water circulation system of the water bag probe. A first three-way valve 6 is installed in the pipeline between the water bag 1 and the refrigeration unit 2, a first pump 5 is installed in the pipeline between the water bag 1 and the first three-way valve 6, and a second three-way valve 7 is installed in the pipeline between the refrigeration unit 2 and the degassing unit 3. The degassing unit 3 deoxygenates the water passing through it to ensure the oxygen content of the water in the air bag 1.

[0027] The water inlet and outlet of the water tank 4 are connected to the third ends of the first three-way valve 6 and the third end of the second three-way valve 7, respectively, via pipelines. Together with the water bladder 1 and the degassing unit 3, they form the external circulation system for water treatment in the present invention. A second pump 8 is provided in the pipeline between the water outlet of the water tank 4 and the third end of the second three-way valve 7. The design of the water tank 4 in the present invention allows for external circulation after water in the water bladder 1 has been lost by controlling the two three-way valves, thereby withdrawing water from the water tank 4 and quantitatively adding water to the water bladder 1.

[0028] In the present invention, the water tank 4 can be a quick-detachable handheld water tank, which is light in weight, small in size, and can be quickly and easily detached. The water tank as a whole can also be replaced, and the replacement is simple and quick. The operator only needs to take out the water tank 4 and install a new water tank 4 to complete the replacement. There is no need for complicated operating steps and additional equipment, which reduces the complexity and risk of the operation. It is more convenient to clean and disinfect, and can effectively clean the inside of the water tank 4. The medium water in the water tank 4 can be replaced frequently to ensure the freshness and purity of the medium water, effectively avoid the generation of impurities inside the water tank 4, ensure the quality of the medium water and the hygiene of the water tank 4, and effectively conduct ultrasonic waves to ensure the effect of treatment.

[0029] Furthermore, a main control board is provided on the water tank 4, which is connected to the heating unit 41 and each sensor via an air plug quick release method. When changing the water, the heating unit 41 and each sensor can be disconnected from the main control board via the air plug quick release method, thereby protecting the heating unit 41 and each sensor. In the present invention, a temperature sensor 11 and a pressure sensor 12 are provided in the water bag 1, which are used to measure the water temperature and water pressure in the water bag 1, respectively, so as to detect the state of the water in the water bag 1 and ensure the safety and effectiveness of the ultrasonic treatment process. If the water temperature and water pressure are abnormal, there will be a risk of skin burns, and there is also the possibility of reduced treatment effect and equipment abnormality. At this time, the surgical system connected to the sensors will issue an error alarm to alert the operator and can also control the disconnection of the power supply to the water bag probe, thereby immediately stopping the treatment to ensure the safety of the patient. The utility model can cool the water in the water bag 1 through the refrigeration unit 2 in the internal circulation, and can also deoxygenate through the aforementioned degassing unit 3, so as to ensure that the water in the water bag 1 is within a normal temperature range and pressure range; in the utility model, the water pressure in the water bag 1 is measured in real time by a pressure sensor, and medium water can be pumped into the water bag 1 through the water circulation to achieve real-time adjustment of the water pressure in the water bag 1, thereby assisting in controlling and adjusting the speed of water inlet and outlet of the water bag 1.

[0030] The water bladder 1 of the present invention uses a pressure sensor 12 to monitor the internal pressure of the water bladder 1, including its filling level and expansion. This data helps determine whether the water bladder 1 is functioning properly and whether it needs adjustment or replacement. It also provides feedback for controlling the operating status of the water treatment device to maintain the pressure within the water bladder 1 within an appropriate range. A temperature sensor monitors temperature changes within the water bladder 1 in real time. Controlling the temperature of the water bladder 1 ensures safety and effectiveness during ultrasound therapy, and allows for timely detection of temperature anomalies within the water bladder 1, allowing for timely temperature regulation through water circulation.

[0031] In the present invention, water can be pumped through a water circulation system to increase water pressure, allowing the medium water to better fill the interior of the water bag 1 and the water pipe, thereby reducing the generation and retention of bubbles. Furthermore, the present invention can also be equipped with bubble separators at the water inlet and outlet of the water bag 1, thereby separating bubbles on the surface of the water bag 1 and further reducing the retention of bubbles.

[0032] Furthermore, the utility model sprays a hydrophilic material on the inner surface of the water bag 1 to increase the water wettability of the inner surface of the water bag 1, thereby achieving the effect of retaining water and further ensuring that bubbles in the water can be effectively discharged.

[0033] In the present invention, the degassing unit 3 is further provided with a gas-liquid pump 32, which is connected to the degassing unit 3 through an air pipe 31 and is used to pump the gas diffused from the degassing unit 3 into the air, thereby discharging the gas in the water circulation pipeline.

[0034] In the present invention, the degassing unit 3 adopts a degassing membrane.

[0035] In the present invention, the water tank 4 is provided with a heating unit 41, a liquid level sensor 42, and an oxygen and temperature sensor 43. The heating unit 41 is used to heat the water in the water tank 4, thereby increasing the water temperature therein; the liquid level sensor 42 is used to measure the liquid level of the water in the water tank 4, and the oxygen and temperature sensor 43 is used to measure the oxygen content and water temperature of the water in the water tank 4. In the present invention, the oxygen and temperature sensor 43 can ensure that the water level in the water tank 4 meets the set requirements, so that the water in the water tank 4 can be quantitatively added to the water bag 1 through external circulation, thereby achieving the target water replenishment.

[0036] In the present invention, a dissolved oxygen meter (not shown in the figure) is further provided in the water tank 4 , which is used to increase the oxygen content of the water in the water tank 4 after dissolving oxygen in the water.

[0037] The working principle of this utility model is as follows:

[0038] The dissolved oxygen in the water in the water bag 1 forms a large number of bubbles under the high frequency and high intensity of ultrasound. The formation of bubbles may cause cavitation. The presence of bubbles will affect the propagation of ultrasound, resulting in energy scattering and attenuation, thereby reducing the treatment effect. At the same time, it will interfere with the uniform distribution of ultrasound and affect the accuracy of treatment. Therefore, it is necessary to reduce the oxygen content in the water bag 1. Under normal temperature and pressure, the dissolved oxygen content of pure water is 8-10 mg / L. The water in the water tank 4 is deoxygenated by the utility model so that the dissolved oxygen content of the water in the water bag 1 reaches the set value. In this embodiment, the set value is preferably 4 mg / L.

[0039] In the present invention, deoxygenation can be performed through an external circulation system. Specifically, the water tank 4 and the water bladder 1 are connected via a first three-way valve 6, and the water tank 4 and the degassing membrane 3 are connected via a second three-way valve 7. The water in the water tank 4 is pumped to the degassing membrane 3 by a second pump 8 for degassing to remove dissolved oxygen in the water. The water then flows into the water bladder 1, and the water in the water bladder 1 is then pumped into the water tank 4 by the first pump 5. The aforementioned process is repeated until the oxygen and temperature measuring sensors 43 in the water tank 4 detect that the dissolved oxygen content has reached a set value. The present invention adjusts the dissolved oxygen content of the water in the water to the set value through external circulation.

[0040] Because the pipes are in contact with air, air will inevitably remain in the pipes during device assembly. This air may enter the water bag 1 during subsequent treatments. Under the action of ultrasound, the air will form bubbles, interfering with the propagation of ultrasound waves and causing reflection of the sound waves, which in turn affects the therapeutic effect. Therefore, after the device is assembled, the air in the pipes needs to be expelled. Specifically, the air in the pipes can be expelled through the following process:

[0041] The water bag 1 and the refrigeration unit 2 are connected through the first three-way valve 6, and the refrigeration unit 2 and the degassing membrane 3 are connected through the second three-way valve 7. The water in the water bag 1 is pumped to the degassing membrane 3 through the first pump 5, so that the air in the liquid can be removed. Then the water flows into the water bag 1, and then the water in the water bag 1 is pumped into the water tank 4 through the first pump 5. The above process is repeated a set number of times.

[0042] Similarly, during the device assembly and the aforementioned pipeline exhaust process, air may also exist in the water bag 1, so the air in the water bag 1 needs to be exhausted. Specifically, the air in the water bag 1 can be exhausted through the following process:

[0043] The water tank 4 and the water bladder 1 are connected via a first three-way valve 6, and the water tank 4 and the degassing membrane 3 are connected via a second three-way valve 7. The water in the water tank 4 is pumped to the degassing membrane 3 by a second pump 6, thereby removing air from the water. The water then enters the water bladder 1 and is then pumped to the water tank 4 by the first pump 5, completing the water cycle. In the present invention, in order to more effectively reduce the oxygen content in the water, a secondary deoxygenation is performed after the first deoxygenation of the aforementioned external circulation is completed, thereby further effectively reducing the oxygen content in the water and further ensuring the therapeutic effect.

[0044] In the present invention, during the treatment process, the emission of ultrasound may produce tiny bubbles, and deoxygenation and degassing need to be continued during the treatment process. The aforementioned secondary deoxygenation cycle is also adopted. Specifically, the device of the present invention can automatically stop the aforementioned secondary deoxygenation cycle when ultrasound is emitted, and when ultrasound is not emitted, the device of the present invention starts the aforementioned secondary deoxygenation cycle to ensure a better treatment effect.

[0045] After the deoxygenation operation is completed, the utility model needs to detect the pressure state in the water bag 1 in real time, and automatically adjust the pressure in the water bag 1 to reach the specified state value through the set water circulation. Specifically:

[0046] The water tank 4 and the water bag 1 are connected through the first three-way valve 6, and the water tank 4 and the degassing membrane 3 are connected through the second three-way valve 7. The water in the water bag 1 is pumped to the water tank 4 through the first pump 5, and then the water in the water tank 4 is pumped to the degassing membrane 3 through the second pump 8. After that, the water enters the water bag 1, and the cycle continues. When the pressure value detected by the pressure sensor 12 in the water bag 1 reaches the specified state value, the adjustment is completed.

[0047] In the present utility model, during actual application, the posture of the water bag 1 is adjusted so that the water inlet of the water bag 1 is at the bottom and the water outlet is at the top, so that the water in the water bag 1 is filled and flows out from the water outlet at the same time, thereby effectively maintaining a balanced state, thereby ensuring that the pressure value in the water bag 1 is kept within the set range to protect the water bag 1 from damage and ensure that the water bag 1 will not be adsorbed on the surface of the probe.

[0048] During treatment, the water in the water bladder 1 needs to be cooled while maintaining pressure. Therefore, the water bladder 1 is connected to the cooling unit 2 via a first three-way valve 6, and the cooling unit 2 is connected to the degassing membrane 3 via a second three-way valve 7. The water in the water bladder 1 is pumped to the cooling unit 2 for cooling via a first pump 5. The water then flows into the degassing membrane 3 for degassing to maintain pressure. Finally, the water flows into the water bladder 1, completing the cycle. Similarly, the device of the present invention automatically stops the cycle when ultrasonic waves are emitted and restarts it when ultrasonic waves are not emitted.

[0049] After the treatment is completed, the water in the water bag 1 needs to be drained. At this time, the water tank 4 and the water bag 1 are connected through the first three-way valve 6, and the water tank 4 and the degassing membrane 3 are connected through the second three-way valve 7. By adjusting the position of the water tank 4, the pipeline connected to the water outlet is separated from the water level in the water tank 4, and the first pump 5 is reversed. However, at this time, the water outlet of the water tank is separated from the water level in the water tank 4. The first pump 5 cannot pump water and can only pump air into the water bag 1, and then discharge it through the pipeline to the degassing membrane 3. The second pump 8 is also reversed to pump air into the water tank 4 through the degassing membrane 3, thereby realizing air circulation, and the water in the water bag 1 can be drained.

[0050] This water treatment device can monitor the status of the water bladder. Through water circulation, it effectively replaces the medium within the bladder and removes tiny bubbles within the bladder. It also deoxygenates and controls the temperature within the bladder, enabling accurate oxygen content measurement to ensure therapeutic efficacy. Furthermore, the device boasts a simple structural design, low power consumption and cost, and convenient assembly.

[0051] The above is only a preferred embodiment of the present invention. The present invention is not limited to the above embodiments. Any technical solutions obtained by equivalent replacement or the like fall within the protection scope of the present invention.
