Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a balloon detection device, balloon detection method, apparatus, and medical device. Background Technology

[0002] Heart failure refers to a series of symptoms caused by insufficient blood perfusion due to impaired heart function, which prevents the heart from completely pumping blood out of the heart. It is divided into acute heart failure and chronic heart failure.

[0003] The current standard treatment for acute heart failure generally involves: initial oxygen therapy, intravenous administration of diuretics and cardiotonics; if the condition does not improve, vasoactive drugs are used to dilate and constrict blood vessels; in severe cases, such as persistently low blood pressure or even cardiogenic shock, hemodynamic monitoring is conducted, and emergency non-pharmacological treatments are employed. Among these, balloon occlusion surgery can effectively reduce the pressure on the heart's pumping mechanism and enhance the return of excess fluid from the interstitial space to the lymphatic system, reducing fluid retention and improving postoperative recovery.

[0004] Since balloons need to be sealed in the human body for a long time to have a noticeable effect, monitoring and detecting whether the balloons leak in the human body is a key issue at present.

[0005] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to be accepted in any prior art. Summary of the Invention

[0038] Heart failure is a common disease among the elderly, affecting approximately 15 million people worldwide. The prevalence increases with age, reaching about 10% of those over 75 years of age. One of the signs of heart failure is poor blood circulation. Among related technologies, balloon angioplasty is a relatively safe and effective treatment for heart failure. By dilating blood vessels with a balloon, more blood can flow to the heart, effectively alleviating heart failure symptoms.

[0039] In related technologies, after the balloon is inflated and deployed inside the body, digital subtraction angiography (DSA) is typically used to detect whether the balloon has leaked. However, this method involves radiation and requires medical staff to intermittently turn on the DSA equipment (e.g., the angiography machine) to monitor the balloon's status. Furthermore, DSA equipment is usually located in the operating room, while balloon closure surgery is a lengthy procedure; most patients spend part of the time in the operating room and the rest of the time in the ward continuing treatment. Therefore, DSA in these technologies cannot monitor the balloon's status in real time, and the detection method is relatively complex.

[0040] This application provides a balloon detection device. By installing a first pressure sensor inside the balloon, the device can monitor the various operating states of the balloon control components in real time based on the detection results of the first pressure sensor under different operating conditions, thereby reducing the risk of accidents caused by leakage or rupture of the balloon during use. By installing a second pressure sensor to detect the liquid pressure between the first tube and the balloon, the device can determine whether the balloon has leaked or ruptured by the pressure changes outside the balloon. Furthermore, combining the detection results of the first pressure sensor with the device further improves the reliability of balloon monitoring.

[0041] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0042] Please refer to Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a balloon detection device 100 provided in some embodiments of this application. Figure 2 Provided for some embodiments of this application Figure 1 Schematic diagram of section AA. Figure 3 Provided for some embodiments of this application Figure 1 A schematic diagram of a cross-section of the balloon (BB). This application provides a balloon detection device 100, including: a balloon 101 configured to block a first tube 200 when inflated; a first pressure sensor 103 disposed inside the balloon 101; a balloon control unit 104 configured to inflate or deflate the balloon 101; and a status detection unit 105 for outputting whether the balloon 101 is damaged based on the operating status of the balloon control unit 104 and the detection result of the first pressure sensor 103.

[0043] The balloon 101 is an inflatable body with a hollow structure. It can be compressed and inflated after being filled with a certain amount of balloon fluid, and remains in an inflated state. The balloon 101 can be located inside the human body (e.g., inside a blood vessel) for occlusion of the blood vessel after inflation. As a feasible implementation, the balloon 101 can also be located inside an artificial first tube 200, which can be a simulated blood vessel in an experimental environment. The balloon 101 can be connected to a balloon catheter 102, and inflation or deflation operations can be performed based on the lumen within the balloon catheter 102. As one possible implementation, the balloon catheter 102 can be a flexible tube with at least one lumen for easy insertion into a blood vessel or the first tube 200. After the balloon 101 is delivered into the blood vessel or the first tube 200, a portion of the balloon catheter 102 attached to the balloon 101 is located inside the blood vessel or the first tube 200, while another portion is located outside the human body or outside the simulated human environment where the first tube 200 is located, to be attached to the balloon inflation / deflation pump 107. The balloon inflation / deflation pump 107 is used to deliver balloon filling fluid through at least one lumen of the balloon catheter 102 into the balloon 101.

[0044] As one possible implementation, the balloon filling fluid includes saline, contrast agent, or a mixture of both. As an optional implementation, the saline and contrast agent in the balloon filling fluid can be mixed in a 1:3 mass percentage ratio.

[0045] The first pressure sensor 103 can be positioned at any suitable location inside the balloon 101 to detect the fluid pressure inside the balloon 101 in real time. The balloon control component 104 generates a control signal to drive the balloon inflation / deflation pump 107 to inflate or deflate the balloon 101. In one possible implementation, the balloon control component 104 operates in four states: inflating the balloon, maintaining inflation, depressurizing the balloon, and maintaining depressurization. For each of these four states, the balloon control component 104 outputs four different control signals, which drive the balloon into the inflated state, the inflated-maintained state, the depressurized state, and the depressurized-maintained state, respectively. Under different operating states of the balloon control component 104, the internal pressure of the balloon 101 changes in real time. Based on the operating state of the balloon control component 104 and the detection results of the first pressure sensor 103, the status detection component 105 can determine in real time whether the balloon 101 is damaged. It is understandable that damage to balloon 101 includes various situations such as balloon 101 cracking, resulting in unstable internal pressure, balloon 101 ruptured but not yet causing leakage of the balloon filling fluid, or balloon 101 ruptured and possibly causing some leakage of the balloon filling fluid.

[0046] By installing a first pressure sensor 103 inside the balloon 101, the detection results of the first pressure sensor 103 under different working conditions can be used to monitor the various working conditions of the balloon control component 104 in real time, thereby reducing the risk of accidents caused by leakage or rupture of the balloon 101 during use to a certain extent.

[0047] According to some embodiments of this application, the balloon detection device 100 further includes a balloon catheter body 102, one end of which is fixedly connected to a balloon 101. A first lumen 1021 is disposed inside the balloon catheter body 102, and the first lumen 1021 is used to transport balloon filling fluid into the balloon. A first pressure sensor 103 is connected to a status detection component 105 via a first pressure sensing line 1031, wherein the first pressure sensing line 1031 is at least partially disposed in the first lumen 1021.

[0048] One end of the first lumen 1021 is connected to the balloon inflation / deflation pump 107, and the other end of the first lumen 1021 communicates with the interior of the balloon 101. The first lumen 1021 is used to transport the balloon filling fluid into the interior of the balloon 101. By placing the first pressure sensing line 1031 within the lumen (more specifically, the first lumen 1021) used for balloon inflation and deflation, the existing balloon catheter body 102 structure can be utilized without the need for additional lumens. Simultaneously, within the limited cross-sectional area of ​​the balloon catheter body 102, the effective proportion of the first lumen 1021 is increased, thereby improving the balloon inflation and deflation efficiency. As a feasible implementation, with a constant cross-sectional area of ​​the first lumen 1021, the diameter of the balloon catheter body 102 can be reduced to a certain extent, thus reducing the size of the device.

[0049] refer to Figures 4-5 , Figure 4 Provided for some embodiments of this application Figure 1 Schematic diagram of section AA. Figure 5 Provided for some embodiments of this application Figure 1 Schematic diagram of cross-section BB in the middle. According to some embodiments of this application, the balloon catheter body 102 of the balloon detection device 100 includes a first lumen 1021 and a second lumen 1022. The first lumen 1021 and the second lumen 1022 are both sleeved inside the balloon catheter body 102, and the first lumen 1021 and the second lumen 1022 are not connected to each other.

[0050] The first cavity 1021 is used to transport the balloon filling fluid into the interior of the balloon 101, and the second cavity 1022 is used to lead the first pressure sensing line 1031 out from the interior of the balloon 101. By setting different cavities, the influence of the pressure sensing line 1031 in the second cavity 1022 on inflation and deflation can be reduced. At the same time, during inflation and deflation, the influence of the balloon filling fluid on the pressure sensing line 1031 can also be reduced, thereby improving the detection accuracy and the durability of the equipment.

[0051] According to some embodiments of this application, such as Figure 4 As shown, the balloon detection device 100 also includes a second pressure sensor 106, which is disposed outside the balloon 101. The second pressure sensor 106 is configured to detect the liquid pressure between the first tube 200 and the balloon 101. The status detection component 105 outputs whether the balloon 101 has leaked based on the operating status of the balloon control component 104, the detection result of the first pressure sensor 103, and the detection result of the second pressure sensor 106.

[0052] The balloon catheter body 102 also includes a third lumen 1023, which is fitted inside the balloon catheter body 102 and is not in communication with the first lumen 1021 and / or the second lumen 1022. The third lumen 1023 can be configured for inserting a guidewire. When the guidewire is withdrawn, the third lumen 1023 is in communication with the first tube body 200, so the fluid in the first tube body 200 enters and fills the third lumen 1023. At this time, the fluid pressure in the third lumen 1023 is measured by the second pressure sensor 106, which is the fluid pressure between the first tube body 200 and the balloon 101.

[0053] Since the balloon 101 exists in different states within the first tube 200, the liquid pressure within the first tube 200 will change with the state of the balloon 101 within the first tube 200. Under different working states of the balloon control component, by acquiring the measurement results of the second pressure sensor 106, it is possible to confirm whether the balloon is in the correct working state. Thus, combined with the measurement results of the first pressure sensor 103, the balloon 103 can be detected, improving detection accuracy and the overall fault tolerance of the equipment.

[0054] refer to Figure 6 , Figure 6 This is a flowchart illustrating a balloon detection method 300 provided in some embodiments of this application. Embodiments of this application provide a balloon detection method 300, including the following steps:

[0055] S310, based on the first working state of the balloon, acquire first pressure detection data, which is used to characterize the internal pressure value of the balloon in the first working state.

[0056] The first working state is one of the following: the balloon 101 is inflated, the balloon 101 is inflated and maintained, the balloon 101 is depressurized, and the balloon 101 is depressurized and maintained.

[0057] S320, compare the first pressure detection data with the first threshold. The first threshold is the internal pressure threshold of the balloon 101 in the corresponding state.

[0058] S330, based on the comparison between the first pressure detection data and the first threshold, determine whether the balloon has leaked.

[0059] Figure 7 This diagram illustrates the trend of first pressure detection data changes in the balloon inflation state during balloon detection methods provided in some embodiments of this application. Figure 7 As shown, when the balloon 101 is inflated, the internal pressure of the balloon 101 undergoes three stages. In the first stage, the internal pressure of the balloon 101 increases slowly; in the second stage, the internal pressure of the balloon 101 increases exponentially; and in the third stage, the internal pressure of the balloon 101 continues to increase slowly until it reaches a stable state. By acquiring and recording the first pressure detection data using the first pressure sensor 103 when the balloon 101 is inflated, it can be compared with the calibrated balloon pressure threshold for the inflated state, i.e., the first threshold corresponding to the inflated state. If the acquired first pressure detection data is greater than the first threshold when the balloon 101 is inflated, the balloon 101 is likely to experience fatigue and leakage. By detecting the first pressure detection data of the first pressure sensor 103 when the balloon 101 is inflated, balloon deformation can be promptly warned, reminding medical staff to replace the balloon in time and avoiding balloon rupture accidents.

[0060] Figure 8 This diagram illustrates the trend of first pressure detection data changes during the balloon deflation state in some embodiments of the balloon detection method provided in this application. Figure 8As shown, when balloon 101 is in the deflated state, the internal pressure of balloon 101 also has three stages. In the first stage, the internal pressure of balloon 101 decreases slowly; in the second stage, the internal pressure of balloon 101 decreases exponentially; and in the third stage, the internal pressure of balloon 101 continues to decrease slowly until the internal pressure of balloon 101 tends to a stable state. By using the first pressure sensor 103 to acquire and record the first pressure detection data when balloon 101 is in the deflated state, it is possible to compare it with the calibrated balloon pressure threshold for the deflated state, i.e., the first threshold corresponding to the deflated state. If the acquired first pressure detection data is greater than the first threshold when balloon 101 is in the deflated state, balloon 101 is likely to experience fatigue and leakage. By detecting the first pressure detection data of the first pressure sensor 103 when balloon 101 is in the deflated state, balloon deformation can be warned in a timely manner, reminding medical staff to replace the balloon promptly and avoiding balloon rupture accidents.

[0061] When the balloon 101 is in the inflation holding state or the depressurization holding state, the pressure inside the balloon 101 should remain stable. If the internal pressure inside the balloon changes during this stage, the balloon 101 will become fatigued and is very likely to leak.

[0062] As a feasible implementation method, with the gradual development of machine learning technology, balloon samples in different states (specifically, including intact balloon samples and damaged balloon samples) and the corresponding pressure data inside each balloon sample in different states can be used as training datasets to train the balloon detection model. Once the balloon detection model is trained, the first pressure detection data detected can be input into the balloon detection model in real time to determine whether the balloon has ruptured or leaked. At this time, the state detection component can be considered as the balloon detection model mentioned above.

[0063] refer to Figure 9 , Figure 9 This is a flowchart illustrating a balloon detection method 400 provided in some embodiments of this application. Embodiments of this application provide a balloon detection method 400, including the following steps:

[0064] S410, based on the first working state of the balloon, acquire first pressure detection data and second pressure detection data. The first pressure detection data is used to characterize the internal pressure of the balloon in the first working state, and the second pressure detection data is used to characterize the liquid pressure between the first tube and the balloon. The first working state is one of the following: balloon inflation state, balloon inflation holding state, balloon depressurization state, and balloon depressurization holding state.

[0065] S420, compare the first pressure detection data with a first threshold, and compare the second pressure detection data with a second threshold. The first threshold is the pressure threshold inside the balloon in the corresponding state, and the second threshold is the liquid pressure threshold between the first tube and the balloon in the corresponding state.

[0066] S430, based on the comparison of the first pressure detection data with the first threshold and the comparison of the second pressure detection data with the second threshold, determine whether the balloon has leaked.

[0067] Since the balloon 101 exists in different states within the first tube 200, the liquid pressure within the first tube 200 will change with the state of the balloon 101 within the first tube 200. Under different working states of the balloon control component, by acquiring the measurement results of the second pressure sensor 106, it is possible to confirm whether the balloon is in the correct working state. Thus, combined with the measurement results of the first pressure sensor 103, the balloon 103 can be detected, improving detection accuracy and the overall fault tolerance of the equipment.

[0068] refer to Figure 10 , Figure 10 This diagram illustrates the trend of first pressure detection data changes during the balloon deflation and holding state in some embodiments of the present application. When the balloon 101 is in the deflation and holding state, the value of the first pressure detection data detected by the first pressure sensor 103 is small and easily affected by breathing and heartbeat, causing the first pressure detection data to fluctuate within a certain range. Therefore, using only the detection data of the first pressure sensor 103 as an indicator to determine whether the balloon has leaked is inaccurate. By introducing the second pressure sensor 106, blood pressure data (i.e., the liquid pressure data between the first tube and the balloon under experimental conditions) can be introduced as a further indicator, which can improve the detection accuracy and the overall fault tolerance of the equipment to a certain extent.

[0069] When the first working state is the balloon inflated state, the balloon inflated and maintained state, and the balloon depressurized state, the weight of the first pressure detection data can be increased, with the balloon internal pressure detection data as the main evaluation indicator to improve the accuracy of balloon detection. When the first working state is the balloon depressurized and maintained state, the value of the balloon internal pressure detection data is relatively small and easily affected by environmental fluctuations. Therefore, in this case, the weight of the first pressure detection data can be reduced, and the weight of the second pressure detection data can be increased to reduce environmental interference to some extent.

[0070] Since the second pressure sensor 106 is typically detected externally, its status is more easily observed. However, the first pressure sensor 103 is located inside the balloon, usually within the body during use, making it difficult to determine whether abnormal data from the first pressure sensor 103 is due to balloon rupture or damage to the sensor itself. Therefore, as a feasible implementation, the weight of the first pressure sensor in determining whether balloon leakage has occurred can be determined based on the comparison between the second pressure detection data and a second threshold.

[0071] refer to Figure 11 , Figure 11 This is a structural block diagram of a balloon detection device 500 provided in some embodiments of this application. The balloon detection device 500 includes: an acquisition module 501, a comparison module 502, and a determination module 503. The acquisition module 501 is configured to acquire first pressure detection data based on a first operating state of the balloon, the first pressure detection data being used to characterize the internal pressure value of the balloon in the first operating state. The comparison module 502 is configured to compare the first pressure detection data with a first threshold. The determination module 503 is configured to determine whether a balloon leak has occurred based on the result of comparing the first pressure detection data with the first threshold. The first operating state is one of a balloon inflated state, a balloon inflated and held state, a balloon depressurized state, and a balloon depressurized and held state; the first threshold is the internal pressure threshold of the balloon in the corresponding state.

[0072] As one possible implementation, the acquisition module 501 can also be configured to acquire first pressure detection data and second pressure detection data based on a first working state of the balloon.
