Description

Technical Field

[0001] This invention relates to the field of medical device technology for abnormal uterine bleeding, and in particular to a device for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding. Background Technology

[0002] Endometrial ablation is a surgical procedure used to treat abnormal uterine bleeding (AUB), especially for patients without structural abnormalities such as uterine fibroids or adenomyosis, and for whom drug therapy has been ineffective. This procedure reduces menstrual flow by destroying the uterine lining, and sometimes can even lead to cessation of menstruation. Surgical methods include using techniques such as radiofrequency, microwave, heated balloons, and cryoablation to ablate the endometrium.

[0003] Among them, the steam ablation system is an endometrial ablation treatment method used to treat menorrhagia (also known as menorrhagia). The steam ablation system uses steam to safely treat menorrhagia by ablating the uterine lining, the source of menorrhagia.

[0004] However, existing steam ablation systems pose a risk of steam leakage, and the removal device after treatment may inflate due to residual gas remaining inside the balloon after deflation caused by the balloon's material properties. Pulling it out at this point could damage the cervical canal and other parts of the body. Summary of the Invention

[0005] To address the shortcomings of existing technologies and the aforementioned problems, this invention provides a device for inflating, deflating, and detecting a steam ablation balloon for abnormal uterine bleeding. This device allows the balloon to fit more tightly against the cervical canal after inflation, resulting in a better seal. After treatment, the balloon can be flattened and adsorbed onto a guide rod, preventing scratches to human tissues during the removal of the treatment device and improving the safety and reliability of the device.

[0006] This invention provides a device for inflating, deflating, and detecting a steam ablation balloon for abnormal uterine bleeding, comprising:

[0007] Handle mechanism;

[0008] A guide rod is provided at the front end of the handle mechanism. The guide rod has multiple cavities inside and multiple air outlets on its outer peripheral wall. The multiple air outlets are connected to the multiple cavities one by one.

[0009] An airbag structure is fitted onto the guide rod. The airbag structure includes multiple independent airbags, and each airbag is connected to an air outlet.

[0010] An air supply system includes multiple air passages, an air supply mechanism, and a negative pressure mechanism. The multiple air passages are connected to multiple chambers in a one-to-one correspondence. The air supply mechanism is used to supply air to the airbags through the air passages, and the negative pressure mechanism is used to vent air from the airbags or provide a negative pressure environment through the air passages.

[0011] According to the present invention, a device for inflating, deflating and detecting steam ablation balloons for abnormal uterine bleeding is provided, wherein a plurality of balloons are respectively arranged in a columnar structure, and smooth guide surfaces are formed at both ends of the balloons. The lengths of the plurality of balloons are arranged in a sequentially decreasing manner toward the direction away from the handle mechanism.

[0012] The present invention provides a device for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding, which further includes a turntable mechanism disposed between the guide rod and the air passage. The turntable mechanism includes a sealing element that seals against the guide rod and the air passage.

[0013] According to the present invention, a device for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The turntable mechanism further includes a turntable bottom cover, a turntable top cover and a plurality of air needle steel tubes. A connecting boss is formed on the side of the turntable bottom cover facing the guide rod. The sealing element is disposed in the connecting boss. The turntable bottom cover is connected to the guide rod through the connecting boss. The turntable top cover is closed on the side of the turntable bottom cover away from the guide rod. The plurality of air needle steel tubes are inserted through the turntable top cover. One end of the air needle steel tube is connected to the cavity tube and the other end is coupled and connected to the air passage.

[0014] The present invention provides a device for inflation and deflation of a steam ablation balloon for abnormal uterine bleeding and a detection device, which further includes a control card and is connected to the gas supply system via a signal connection.

[0015] According to the present invention, a device for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The gas supply mechanism includes a gas source, a filter and a gas storage tank. The filter is connected between the gas source and the gas storage tank. The gas storage tank is connected to multiple gas lines respectively. The gas source is connected to the control card via signal.

[0016] According to the present invention, a device for inflating, deflating and detecting a steam ablation balloon for abnormal uterine bleeding is provided. The gas circuit includes a gas supply circuit and a negative pressure circuit. The gas supply circuit is connected between the balloon and the gas supply mechanism, and the negative pressure circuit is connected between the negative pressure mechanism and the balloon.

[0017] According to the present invention, a device for inflation and deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The gas supply circuit is provided with a gas supply on / off valve, a gas supply pressure regulating valve and a gas supply one-way valve in sequence from the gas supply mechanism toward the balloon. The gas supply on / off valve, the gas supply pressure regulating valve and the gas supply one-way valve are all connected to the control card for signal connection.

[0018] According to the present invention, a device for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The negative pressure circuit is provided with a negative pressure on / off valve and a three-way valve in sequence from the negative pressure mechanism toward the balloon. Both the negative pressure on / off valve and the three-way valve are connected to the control card signal. The inlet of the three-way valve is connected to the outlet of the negative pressure on / off valve. The first outlet of the three-way valve is connected to the external environment, and the second outlet of the three-way valve is connected to the negative pressure mechanism.

[0019] According to the present invention, a device for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The gas supply system further includes a first pressure gauge, which is located at the front end of the gas supply mechanism and is used to detect the gas pressure value of the gas supply mechanism.

[0020] And / or, the gas supply system further includes a plurality of second pressure gauges, which are respectively installed on a plurality of gas lines and located at the front end of the gas supply circuit and the negative pressure circuit. The second pressure gauges are used to detect the gas pressure value of the airbag.

[0021] This invention provides a device for inflating, deflating, and detecting steam ablation balloons for abnormal uterine bleeding. By designing each balloon in the balloon structure with a specific shape (such as an ellipsoid), it can better adapt to the anatomical structure of the cervical canal after inflation. This ensures a tight fit between the balloon and the cervical canal, thus forming an effective sealing environment. Multiple air paths in the air supply system are connected one-to-one with multiple cavities within the guide rod, and each balloon can be controlled through an independent air path. This allows for individual pressure adjustment of each balloon, ensuring that all balloons reach optimal inflation and improving the overall sealing effect. The pressure of each balloon is monitored in real time through the air supply mechanism and the negative pressure mechanism, and adjustments are made as necessary. This helps maintain stable air pressure and prevents leakage due to pressure fluctuations.

[0022] After treatment, the airbags are deflated and negative pressure is applied via a negative pressure mechanism. This mechanism quickly expels or removes air from the airbags, flattening them and placing them firmly against the guide rod. Each airbag's air path can be independently controlled, allowing for individual deflation and negative pressure treatment. This ensures all airbags are flattened, reducing their volume and facilitating safe removal. The flattened airbags reduce their contact area with surrounding tissues, lowering the risk of scratching or compressing sensitive areas such as the cervix during removal. This improves the safety and reliability of the entire treatment process. Furthermore, individual airbags can be inflated or deflated as needed, increasing the device's adaptability.

[0046] The following is combined Figures 1 to 9 The present invention provides a detailed description of a vapor ablation balloon inflation / deflation and detection device for abnormal uterine bleeding, through specific embodiments and application scenarios.

[0047] In the embodiments of the invention, reference is made to... Figures 1 to 7A device 10 for inflating, deflating, and detecting a steam ablation balloon for abnormal uterine bleeding includes a handle mechanism 100, a guide rod 200, a balloon structure 300, and a gas supply system 400. The guide rod 200 is located at the front end of the handle mechanism 100, and has multiple cavities 210 inside. Multiple air outlets 220 are provided on the outer peripheral wall of the guide rod 200, and each air outlet 220 is connected to one of the multiple cavities 210. The balloon structure 300 is sleeved on the guide rod 200. The bladder structure 300 includes multiple independent air bladders 310, each air bladder 310 being connected to an air outlet 220. The air supply system 400 includes multiple air passages 410, an air supply mechanism 420, and a negative pressure mechanism 430. Each air passage 410 is connected to a multiple cavity tube 210. The air supply mechanism 420 is used to supply air to the air bladders 310 through the air passages 410, and the negative pressure mechanism 430 is used to vent air from the air bladders 310 or provide a negative pressure environment through the air passages 410.

[0048] The handle mechanism 100 is the operating center of the entire device, through which doctors control and operate the entire balloon inflation / deflation and monitoring system. The handle is ergonomically designed to ensure comfortable and convenient operation for doctors during use.

[0049] The handle mechanism 100 provides a gripping point, facilitating the surgeon's operation during the procedure. Various control buttons or knobs can be integrated into the handle mechanism 100 for starting, stopping, and adjusting the inflation and deflation process of the airbag 310.

[0050] The guide rod 200 serves as a bridge connecting the handle and the airbag structure 300, providing physical support. The guide rod 200 also has multiple built-in cavities 210, which are used to transmit gas to each airbag 310.

[0051] Each cavity 210 corresponds to one airbag 310, ensuring that gas can be independently delivered to each airbag 310, thereby enabling individual control of each airbag 310.

[0052] The air outlet 220 corresponds one-to-one with the cavity tube 210, so that the gas can accurately enter the corresponding airbag 310, ensuring that the expansion state of each airbag 310 is consistent and controllable.

[0053] The guide rod 200 is provided with multiple air vents 220 to allow the use of different numbers of airbags 310, thereby improving the flexibility and applicability of the device.

[0054] The airbag structure 300 is the part that directly contacts the uterine wall, responsible for creating a sealed environment and withstanding vapor pressure. Multiple airbags can be a single, connected structure or relatively independent structures installed and fixed using adhesives or other methods.

[0055] Each airbag 310 is designed in a specific shape (such as cylindrical, ellipsoidal, or quasi-ellipsoidal) to better conform to the anatomical structure of the cervical canal and enhance the sealing effect.

[0056] Each airbag 310 is connected to an air outlet 220 in a one-to-one manner, ensuring that each airbag 310 receives a gas supply from the guide rod 200 cavity 210, achieving precise control. It can also be selectively inflated or deflated as needed, improving the targeted nature and effectiveness of the treatment.

[0057] The gas supply system 400 is responsible for supplying, regulating and monitoring the gas pressure inside the airbag 310.

[0058] Each air passage 410 corresponds to one airbag 310, ensuring that gas can be delivered independently to each airbag 310, enabling individual control of each airbag 310.

[0059] The gas supply mechanism 420 includes components such as an air pump, an air tank 423, and a pressure regulating valve, which are used to generate and regulate gas pressure to ensure that each airbag 310 can reach the optimal inflation state.

[0060] The negative pressure mechanism 430 is used to exhaust air or provide a negative pressure environment, allowing the airbag 310 to quickly flatten and fit tightly against the guide rod 200 after treatment, facilitating safe removal and reducing the risk of secondary injury. Simultaneously, each airway 410 can be deflated individually, offering high flexibility; if it is necessary to deflate the distal airbag 310 to continue treatment of the portion it obstructs, that airway is deflated.

[0061] In some embodiments, the pressure of each airbag 310 can be monitored in real time by a pressure sensor and a control system, and adjustments can be made as necessary to maintain a stable air pressure and prevent leakage.

[0062] This application designs each airbag 310 in the airbag structure 300 with a specific shape (such as an ellipsoid) to better adapt to the anatomical structure of the cervical canal after inflation. This ensures a tight fit between the airbag 310 and the cervical canal, thus forming an effective sealing environment. Multiple air passages 410 in the air supply system 400 are connected one-to-one with multiple cavities 210 within the guide rod 200, allowing each airbag 310 to be controlled via an independent air passage 410. This enables individual pressure adjustment for each airbag 310, ensuring all airbags 310 reach optimal inflation and improving the overall sealing effect. The pressure of each airbag 310 is monitored in real time through the air supply mechanism 420 and the negative pressure mechanism 430, and adjustments are made as necessary. This helps maintain stable pressure and prevents leakage due to pressure fluctuations.

[0063] After treatment, the airbag 310 is deflated and negative pressure is applied via the negative pressure mechanism 430. The negative pressure mechanism 430 can quickly expel or evacuate the gas inside the airbag 310, flattening it and placing it tightly against the guide rod 200. The air passage 410 of each airbag 310 can be independently controlled, allowing for separate deflation and negative pressure treatment of each airbag 310. This ensures that all airbags 310 are flattened, reducing their volume and facilitating safe removal. The flattened airbags 310 reduce the contact area with surrounding tissues, lowering the risk of scratching or compressing sensitive areas such as the cervix during removal. This improves the safety and reliability of the entire treatment process. Furthermore, individual airbags 310 can be inflated or deflated as needed, increasing the device's adaptability.

[0064] Reference Figures 1 to 3 According to the present invention, a device 10 for inflation, deflation and detection of steam ablation balloon for abnormal uterine bleeding is provided. Multiple airbags 310 are respectively arranged in a columnar structure, and smooth guide surfaces are formed at both ends of the airbags 310. The long radius of the multiple airbags 310 is arranged in a sequentially decreasing manner in the direction away from the handle mechanism 100.

[0065] Understandably, cylindrical structures can include shapes such as cylinders, ellipsoids, and quasi-ellipsoids. In gynecological surgery, the shape and size of the uterus vary from person to person. A cylindrical balloon 310 can better conform to the contours of the uterus, providing uniform and effective pressure, thereby controlling bleeding more effectively. At the same time, the cylindrical shape also allows the balloon 310 to more easily adapt to the shape of the uterus during inflation and deflation, reducing potential damage to uterine tissue.

[0066] From the airbag 310 closest to the handle mechanism 100 to the airbag 310 furthest from the handle mechanism 100, the long radius of each airbag 310 gradually decreases. In this way, as the airbags 310 extend distally, their gradually decreasing size can better adapt to the gradually shrinking or conical structure of the uterus, ensuring that the entire uterus receives uniform and effective compression.

[0067] Reference Figures 1 to 5 According to the present invention, a steam ablation balloon inflation and deflation and detection device 10 for abnormal uterine bleeding further includes a turntable mechanism 500, which is disposed between the guide rod 200 and the air passage 410. The turntable mechanism 500 includes a sealing element 510, which is sealed and abuts against the guide rod 200 and the air passage 410.

[0068] Understandably, the turntable mechanism 500 is used to establish the connection and relative position between the guide rod 200 and the air passage 410. During inflation and deflation, the guide rod 200 is responsible for transmitting operating commands or physical connections, while the air passage 410 is responsible for the flow of gas. The turntable mechanism 500, as an intermediate connecting mechanism, ensures effective communication between the air passage 410 and the cavity tube 210, allowing gas to flow to the designated airbag 310 as needed.

[0069] During the steam ablation treatment of the uterine wall, the steam needs to be sealed to prevent steam leakage and burns to the vagina, cervix and other healthy tissues. The seal 510 is located in the turntable mechanism 500 and is sealed between the guide rod 200 and the air passage 410 to prevent gas or liquid from leaking from the gap between the two.

[0070] Reference Figures 2 to 5 According to the present invention, a device 10 for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The turntable mechanism 500 further includes a turntable bottom cover 520, a turntable top cover 530 and a plurality of air needle steel tubes 540. A connecting boss 521 is formed on the side of the turntable bottom cover 520 facing the guide rod 200. A sealing member 510 is disposed in the connecting boss 521. The turntable bottom cover 520 is connected to the guide rod 200 through the connecting boss 521. The turntable top cover 530 covers the side of the turntable bottom cover 520 away from the guide rod 200. A plurality of air needle steel tubes 540 are inserted on the turntable top cover 530. One end of the air needle steel tube 540 is connected to the cavity tube 210 and the other end is coupled and connected to the air passage 410.

[0071] Understandably, the connecting boss 521 formed on the side of the turntable bottom cover 520 facing the guide rod 200 is the connection point between the turntable mechanism 500 and the guide rod 200. This ensures that the turntable mechanism 500 can be stably fixed to the device while allowing it to rotate or adjust as necessary. A seal 510 is provided inside the connecting boss 521, which fits tightly between the end faces of the guide rod 200 and the turntable base, ensuring that the gas flow is controllable and leak-proof. The turntable top cover 530 covers the side of the turntable bottom cover 520 away from the guide rod 200, forming a closed space. Multiple air needle steel tubes 540 are threaded through the turntable top cover 530; these tubes are channels connecting the cavity tube 210 and the gas passage 410. One end of each air needle steel tube 540 communicates with the cavity tube 210, and the other end is coupled to the gas passage 410. This ensures that gas can flow from one gas passage 410 to another as needed, thereby achieving control over the inflation and deflation of the airbag 310.

[0072] Reference Figure 6 The device 10 for inflation, deflation and detection of steam ablation balloon for abnormal uterine bleeding provided by the present invention also includes a control card 600, which is connected to the gas supply system 400 via signal.

[0073] Understandably, the control card 600 communicates with the gas supply system 400 via signals and can automatically control the operation of the gas supply system 400, such as inflation, deflation, and pressure regulation. The control card 600 can precisely control the pressure and flow output of the gas supply system 400 based on preset programs or real-time monitoring data. For example, the control card 600 can automatically adjust the pressure inside the balloon based on real-time data provided by the detection system to achieve optimal hemostasis or diagnostic accuracy.

[0074] Reference Figure 6 According to the present invention, a device 10 for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The gas supply mechanism 420 includes a gas source 421, a filter 422 and a gas storage tank 423. The filter 422 is connected between the gas source 421 and the gas storage tank 423. The gas storage tank 423 is connected to multiple gas lines 410 respectively. The gas source 421 is connected to a control card 600.

[0075] Understandably, gas source 421 provides the source of gas, which can be compressed air, inert gas, or other gases suitable for medical use. It is the power source for the entire gas supply system 400.

[0076] The filter 422 is connected between the gas source 421 and the gas tank 423. Its function is to filter out impurities (such as dust, moisture, oil mist, etc.) in the gas, ensuring the purity of the gas entering the gas tank 423 and the subsequent gas path 410. This is because any impurities may pose unnecessary risks to the patient or affect the performance of the equipment.

[0077] The gas storage tank 423 is used to store filtered gas so that it can be quickly and stably supplied to the balloon when needed. The gas storage tank 423 also acts as a buffer to balance fluctuations in the output of the gas source 421 and ensure the stability of the gas supply.

[0078] In this embodiment, the gas source 421 is automatically controlled by the control card 600. The control card 600 can accurately control parameters such as gas flow rate, pressure and filling / discharging time, thereby improving the intelligence level of the entire device.

[0079] Reference Figure 6 According to the present invention, a device 10 for inflation, deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The air circuit 410 includes an air supply circuit 411 and a negative pressure circuit 412. The air supply circuit 411 is connected between the balloon 310 and the air supply mechanism 420, and the negative pressure circuit 412 is connected between the negative pressure mechanism 430 and the balloon 310.

[0080] Understandably, the air supply circuit 411 is connected between the airbag 310 and the air supply mechanism 420. When needed, the air supply mechanism 420 supplies gas to the airbag 310 through the air supply circuit 411, causing it to inflate to a predetermined size and pressure. The air supply circuit 411 may include components such as a flow control valve and a pressure sensor to ensure that gas enters the airbag 310 at a predetermined flow rate and pressure.

[0081] A negative pressure circuit 412 connects the balloon 310 and the negative pressure mechanism 430. When needed, the negative pressure mechanism 430 extracts gas from the balloon 310 through the negative pressure circuit 412, causing it to contract. This is used to adjust the pressure of the balloon 310, release pressure on the uterine wall, or completely deflate the balloon 310 after treatment. The negative pressure circuit 412 may include components such as a negative pressure pump, a pressure sensor, and a flow control valve to precisely control the magnitude and duration of the negative pressure.

[0082] Reference Figure 6 and Figure 8 According to the present invention, a device 10 for inflation and deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The gas supply circuit 411 is provided with a gas supply on / off valve 440, a gas supply pressure regulating valve 450 and a gas supply one-way valve 460 in sequence from the gas supply mechanism 420 toward the balloon 310. The gas supply on / off valve 440, the gas supply pressure regulating valve 450 and the gas supply one-way valve 460 are all connected to the control card 600 for signal connection.

[0083] Understandably, the gas supply on / off valve 440 is located at the very beginning of the gas supply circuit 411 and is responsible for controlling the gas supply. It opens or closes according to the instructions of the control card 600 to determine whether to supply gas to the airbag 310. The gas supply on / off valve 440 is connected to the control card 600 via a signal connection, enabling precise on / off control to ensure that gas is supplied only when needed. When gas supply is not required, the gas supply on / off valve 440 can completely cut off the gas source 421, preventing accidental inflation and improving operational safety.

[0084] The gas supply pressure regulating valve 450, located after the gas supply on / off valve 440, is responsible for regulating the gas supply pressure. This adjusts the high-pressure gas supplied by the gas supply mechanism 420 to a pressure range suitable for inflating the airbags 310. The gas supply pressure regulating valve 450 is connected to the control card 600 via a signal connection. Based on preset parameters or real-time monitoring data, the gas supply pressure regulating valve 450 automatically adjusts the output pressure to ensure that each airbag 310 receives an appropriate inflation pressure. Different patients may require different inflation pressures; the gas supply pressure regulating valve 450 can flexibly adjust according to specific circumstances to optimize treatment effectiveness.

[0085] The gas supply check valve 460, located after the gas supply pressure regulating valve 450, ensures that gas can only flow in one direction, from the gas supply mechanism 420 to the air bladder 310, and cannot flow in the opposite direction. During inflation, the check valve prevents gas from flowing back from the air bladder 310 to the gas supply system 400, ensuring stable pressure within the air bladder 310. During deflation or other operations, the gas supply check valve 460 prevents gas backflow, avoiding unnecessary risks and ensuring operational safety.

[0086] The gas supply on / off valve 440, the gas supply pressure regulating valve 450, and the gas supply check valve 460 are all connected to the control card 600 via signal, enabling the control card 600 to directly control these valves via electrical signals. This achieves automated control of the entire gas supply circuit 411, reduces the need for manual operation, and improves the accuracy and efficiency of operation.

[0087] Reference Figure 6 and Figure 9 According to the present invention, a device 10 for inflation and deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The negative pressure circuit 412 is provided with a negative pressure on / off valve 470 and a three-way valve 480 in sequence from the negative pressure mechanism 430 toward the balloon 310. Both the negative pressure on / off valve 470 and the three-way valve 480 are connected to the control card 600. The inlet of the three-way valve 480 is connected to the outlet of the negative pressure on / off valve 470. The first outlet of the three-way valve 480 is connected to the external environment. The second outlet of the three-way valve 480 is connected to the negative pressure mechanism 430.

[0088] Understandably, the main function of the negative pressure on / off valve 470 is to control the opening and closing of the negative pressure circuit 412. When the control card 600 sends an opening signal, the negative pressure on / off valve 470 opens, allowing the negative pressure mechanism 430 to extract or expel gas from the airbag 310 through the negative pressure circuit 412; when the control card 600 sends a closing signal, the negative pressure on / off valve 470 closes, cutting off the negative pressure circuit 412 and preventing external air or gas from the negative pressure mechanism 430 from entering the airbag 310.

[0089] The three-way valve 480 is a valve with three connection ports, allowing gas to switch between two different paths. In the negative pressure circuit 412 of this invention, the inlet of the three-way valve 480 is connected to the outlet of the negative pressure on / off valve 470, the first outlet is connected to the external environment, and the second outlet is connected to the negative pressure mechanism 430. When the three-way valve 480 switches to this path, gas inside the airbag 310 is allowed to be released into the external environment through the negative pressure circuit 412. This is mainly used to expel gas from the airbag 310 after treatment or testing.

[0090] When the three-way valve 480 switches to this path, the negative pressure mechanism 430 is allowed to extract gas from the airbag 310 through the negative pressure circuit 412, achieving negative pressure deflation. This helps to adjust the pressure of the airbag 310, or to quickly release the gas in the airbag 310 when needed, so that the airbag 310 is flat against the guide rod 200, avoiding pain for the patient when the treatment handle is withdrawn.

[0091] Reference Figure 6 According to the present invention, a device 10 for inflation and deflation and detection of steam ablation balloon for abnormal uterine bleeding is provided. The gas supply system 400 further includes a first pressure gauge 424, which is located at the front end of the gas supply mechanism 420 and is used to detect the gas pressure value of the gas supply mechanism 420.

[0092] Understandably, the first pressure gauge 424 is installed at the front end of the gas supply mechanism 420, and can directly measure and display the gas pressure value provided by the gas supply mechanism 420. By detecting the gas pressure value of the gas supply mechanism 420 through the first pressure gauge 424, the first pressure gauge 424 helps to ensure gas pressure stability. The first pressure gauge 424 is connected to the control card 600, and the control card 600 can adjust the gas supply rate of the gas source 421 in real time according to the pressure value of the first pressure gauge 424 to ensure the stability of the gas pressure supply.

[0093] Reference Figure 6 and Figure 8 According to the present invention, a device 10 for inflation and deflation and detection of a steam ablation balloon for abnormal uterine bleeding is provided. The gas supply system 400 further includes a plurality of second pressure gauges 490. The plurality of second pressure gauges 490 are respectively disposed on a plurality of gas paths 410 and are located at the front end of the gas supply circuit 411 and the negative pressure circuit 412. The second pressure gauges 490 are used to detect the gas pressure value of the balloon 310.

[0094] Understandably, the second pressure gauge 490 is used to detect the air pressure value of the corresponding airbag 310 on each airway 410, to detect whether the airbag 310 is leaking, and also to detect whether the air pressure of each airbag 310 is too high. If the air pressure value of the airbag 310 is too high, an alarm will be issued to remind medical staff. The second pressure gauge 490 is connected to the control card 600 to feed back the air pressure value of each airbag 310 to the control card 600, which then controls the air supply mechanism 420 or the negative pressure mechanism 430 to work according to relevant instructions or preset programs.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
