Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary equipment, and in particular to a limb restraint device for interventional surgery. Background Art

[0002] During interventional surgery, the patient's limbs often need to be restrained to ensure the smooth progress of the surgery and prevent the patient from making unconscious movements that affect the surgical operation. Traditional limb restraints mostly adopt a fixed design, that is, the restraint strength and position are pre-adjusted before the surgery according to the patient's body shape and surgical requirements, and remain unchanged during the surgery. However, this fixed restraint device has many shortcomings.

[0003] First, since the patient's physical condition may change during the operation, such as struggling or agitation due to pain, tension or the effects of drugs, the fixed restraint device cannot be adjusted in time according to the patient's actual situation, which may cause the patient to be over-restrained or under-restrained, thereby affecting the safety of the operation and the patient's comfort.

[0004] Secondly, most traditional restraints need to be adjusted manually, which not only increases the workload of medical staff, but also may affect the efficiency and success rate of the operation due to untimely or improper adjustment. In addition, manual adjustment may also lead to misjudgment and misoperation due to human factors, further increasing the risk of surgery.

[0005] Furthermore, the design of some restraint devices may not be reasonable, such as unstable position, occupying surgical operation space, etc., which not only affects the smooth progress of the operation, but may also have an adverse effect on the safety and comfort of the patient.

[0006] Therefore, in view of the shortcomings of the existing technology, it is necessary to provide a limb restraint device for interventional surgery that can monitor the patient's condition in real time and automatically adjust the restraint force to better meet the safety and comfort requirements during the operation. Summary of the invention

[0007] To solve the above problems, the present invention provides a limb restraint device for interventional surgery, which monitors and automatically adjusts the patient's limb restraints in real time through integrated monitoring technology and automated adjustment mechanism, aiming to improve safety during surgery and patient comfort while reducing the workload of medical staff.

[0008] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a limb restraint device for interventional surgery, comprising a DSA operating table, a plurality of fixing components for fixing the restraint device are installed on the top of the DSA operating table, the restraint device comprises a mounting plate, one side of the mounting plate is fixedly connected to the fixing component, the other side of the mounting plate is fixedly connected to an arc-shaped rod, the arc-shaped rod is a hollow structure, a power piece is also fixedly connected to the mounting plate, the output shaft of the power piece passes through the arc-shaped rod, and the outer wall of the output shaft is sleeved with a gear ring, an arc-shaped rack is embedded in the arc-shaped rod, the arc-shaped rack is meshed with the gear ring, and grooves matching the arc-shaped rack are provided at both ends of the arc-shaped rod;

[0009] It also includes a controller and a monitoring component, the monitoring component is used to monitor the patient's status information in real time, the monitoring component and the power component are both connected to the controller signal, and the controller issues corresponding instructions to the power component according to the patient's status information fed back by the monitoring component;

[0010] When the monitoring component detects that the patient is struggling when using the restraint device, the controller sends a tightening command to the power member, so that the power member drives the arc-shaped rack to move inward along its arc direction to increase the restraint force on the patient;

[0011] When the monitoring component detects that the patient is in a relaxed state when using the restraint device, the controller sends a relaxation command to the power component, causing the power component to drive the arc-shaped rack to move outward along the curvature of the arc-shaped rod, so as to reduce the restraining force on the patient.

[0012] The technical principle of the above scheme is as follows: the fixing component is installed on the top of the DSA operating table to fix the restraint device and ensure its stability during the operation.

[0013] The restraint device is connected to the fixed component through a mounting plate. The arc-shaped rod serves as the main part for restraining the patient, and an arc-shaped rack is embedded in its hollow structure. The output shaft of the power component passes through the arc-shaped rod and is sleeved with a gear ring, which meshes with the arc-shaped rack. In this way, when the power component is working, the gear ring can drive the arc-shaped rack to move along its arc direction, thereby changing the restraining force of the arc-shaped rod on the patient. The controller receives the patient status information fed back by the monitoring component, and issues corresponding instructions to the power component based on this information. The monitoring component monitors the patient's status in real time, such as struggling or calming, and feeds this information back to the controller.

[0014] The above scheme has the following beneficial effects:

[0015] 1. This solution can more effectively ensure the safety and comfort of patients during surgery by monitoring the patient's condition in real time and automatically adjusting the restraint force compared to the fixed restraint devices in the prior art. When the patient's struggle is detected, the device can respond quickly and increase the restraint force to prevent the patient from affecting the surgical operation due to excessive movement; when the patient's condition is stable, the restraint force is automatically reduced to reduce the patient's sense of restraint and improve the comfort of the surgical process.

[0016] 2. This solution adopts a design in which a power part drives the arc-shaped rack to move along the arc direction of the arc-shaped rod. Compared with the manual adjustment or fixed restraint in the prior art, it has higher flexibility and automation. Doctors or nurses can accurately adjust the restraint force without manual operation, so they can focus more on the surgical operation and improve the efficiency and safety of the operation.

[0017] 3. The restraint device of this solution is connected to the fixed assembly through the mounting plate and installed on the top of the DSA operating table. Compared with the problem that the position of the restraint device may be unstable or affect the surgical operation space in the prior art, the stability and reliability of the restraint device during the operation are ensured. At the same time, the design of the arc rod also fully considers the ergonomic principles, which can better adapt to the shape of the patient's limbs and reduce the patient's discomfort.

[0018] 4. This solution also has the characteristics of intelligent control. The controller receives the signal of the monitoring component and issues instructions to achieve automatic adjustment of the restraint force. Compared with the existing technology that requires manual judgment and adjustment, this intelligent control method not only improves work efficiency, but also reduces the risk of human misjudgment and misoperation, further improving the safety and reliability of the operation.

[0019] Furthermore, the monitoring component includes a heart rate monitor, a blood pressure monitor, an electromyographic sensor, and a pressure sensor, wherein the heart rate monitor is used to monitor the patient's heart rate changes in real time, the blood pressure monitor is used to monitor the patient's blood pressure fluctuations in real time, the electromyographic sensor is used to monitor the patient's tiny muscle activities, and the pressure sensor is used to detect the pressure exerted on the patient by the restraint device;

[0020] The struggling state of the status information is manifested as: the heart rate monitored by the heart rate monitor, the heart rate monitored by the blood pressure monitor, the muscle activity detected by the electromyography sensor, and the pressure monitored by the pressure sensor all exceeding a preset threshold;

[0021] The stable state is manifested as: the heart rate monitored by the heart rate monitor, the heart rate monitored by the blood pressure monitor, the muscle activity detected by the electromyography sensor, and the pressure monitored by the pressure sensor, all of which do not exceed the preset thresholds.

[0022] Beneficial effects: The heart rate monitor and blood pressure monitor can capture the patient's heart rate and blood pressure changes in real time, which are important indicators for evaluating the patient's intraoperative status. The electromyography sensor can monitor the patient's tiny muscle movements, which is crucial for determining whether the patient is struggling or trying to move. Through the analysis of electromyography signals, the system can more accurately identify the patient's behavioral intentions, thereby adjusting the strength of the restraint device in advance to avoid excessive or insufficient restraint. The pressure sensor can monitor the pressure exerted on the patient by the restraint device in real time to ensure that the restraint force is both safe enough and not too harsh.

[0023] By using a variety of monitoring methods such as heart rate, blood pressure, electromyography and pressure, doctors can have a more comprehensive understanding of the patient's overall condition and make more accurate decisions. This not only helps improve surgical efficiency and reduce the risk of interrupting surgery due to unstable patient conditions, but also allows for rapid intervention in emergency situations to protect the patient's life safety.

[0024] Furthermore, an anti-pressure sore component is installed on the side wall of the arc rod, and the anti-pressure sore component includes a first airbag and a second airbag, and the first airbag and the second airbag are both installed on the outer side wall of the arc rod, and the first airbag and the second airbag are both provided with an air inlet and an air outlet, and the inlets are connected to an air pump, and the air inlet and the air outlet are both installed with a one-way valve, and the air pump and the one-way valve are both connected to the controller signal, and the controller performs opening and closing instructions on the power part and the one-way valve according to the monitoring data of the monitoring component; the monitoring component also includes a temperature sensor and a humidity sensor, and the temperature sensor and the humidity sensor are both installed on the side of the first airbag and the second airbag away from the arc rod.

[0025] Beneficial effects: The first airbag and the second airbag are the core parts of the anti-pressure sore component. Through the control of the air pump, the air can be periodically inflated and deflated, thereby changing the contact pressure and distribution with the patient's skin. This dynamic pressure change helps to reduce the local blood circulation disorder caused by long-term fixed compression and effectively prevent the formation of pressure sores. The controller intelligently adjusts the opening and closing of the power parts and the one-way valve according to the monitoring data of the monitoring component (such as temperature and humidity) to achieve precise control of the inflation and deflation of the airbag. This intelligent adjustment method not only ensures the safety of the patient, but also greatly improves the comfort during the operation. The addition of temperature sensors and humidity sensors enables the system to monitor the microenvironment near the patient's skin in real time. When the temperature and humidity exceed the normal range, the controller can issue a warning or adjust the inflation and deflation state of the airbag to maintain a suitable microenvironment on the skin surface and further reduce the risk of skin damage. Through the intelligent control system, doctors or nurses do not need to frequently manually adjust the inflation and deflation state of the airbag, thereby reducing the frequency of manual intervention. This not only improves work efficiency, but also reduces the potential risks caused by human operational errors.

[0026] Furthermore, it also includes an auxiliary component for alleviating pressure ulcers on the patient's skin. The auxiliary component includes a connecting plate, which is fixedly connected to the outer wall of the arc tube between the first airbag and the second airbag. A slide plate is slidably fitted on the connecting plate, and push plates are fixedly connected at both ends of the slide plate, and a massage piece is fixedly connected to one side of the push plate.

[0027] Beneficial effects: The massage parts in the auxiliary components can further massage the skin on the basis of inflation and deflation of the airbag through the sliding cooperation of the push plate and the slide plate. This massage effect helps to promote local blood circulation and reduce blood circulation disorders caused by long-term compression, thereby reducing the risk of pressure sores. The massage effect of the auxiliary component is automatically achieved by the sliding of the slide plate, without manual operation. This reduces the frequency of manual intervention by medical staff during the operation, allowing them to focus more on the surgical operation itself, improving surgical efficiency and safety. By adding auxiliary components to the restraint device, the device not only has a restraint function, but also has multiple functions of preventing pressure sores and massaging the skin. This multifunctional design makes the restraint device more practical and efficient in interventional surgery.

[0028] Furthermore, it also includes an early warning module, which is connected to the monitoring component signal. When the heart rate monitored by the heart rate monitor, the heart rate monitored by the blood pressure monitor, the muscle activity detected by the electromyography sensor and the pressure monitored by the pressure sensor in the monitoring component exceed the preset safety range, the early warning system is automatically triggered to issue an early warning message to remind medical staff to take measures.

[0029] Beneficial effects: The early warning module can monitor the patient's physiological parameters in real time and immediately trigger an early warning when these parameters exceed the preset safety range. This immediate response mechanism ensures that medical staff can quickly identify potential risks and take immediate measures to effectively avoid or mitigate possible adverse effects on patients. By setting reasonable physiological parameter thresholds, the early warning module can provide an additional layer of safety for patients during surgery. Once the patient's physiological state fluctuates abnormally, the early warning system will immediately sound an alarm to remind medical staff to pay attention and deal with it in time, thereby significantly improving the safety of the operation. Through real-time monitoring and early warning, medical staff can promptly detect and deal with abnormal conditions of patients, thereby effectively reducing medical disputes and risks caused by medical negligence or improper operation.

[0030] Furthermore, a protective layer is fixedly connected to one side of the arc-shaped rack.

[0031] Beneficial effects: As the part that is in direct contact with the patient's skin, the protective layer's soft and smooth properties can effectively reduce the friction and pressure of the curved rack on the patient's skin, and prevent the skin from being damaged, red, swollen, or pressure sores due to long-term pressure or friction. The presence of the protective layer makes the curved rack softer and more fitted when restraining the patient's limbs, reduces the discomfort of the hard structure to the patient's skin, and improves the patient's overall comfort during the operation. The protective layer not only protects the patient's skin, but also plays a certain buffering role. In unexpected situations, such as sudden movement or struggle of the patient, the protective layer can reduce the impact of the curved rack on the patient's skin and reduce the risk of skin damage. As an isolation layer between the curved rack and the patient's skin, the protective layer can reduce the wear and corrosion of the curved rack caused by direct contact with the skin. This helps to extend the service life of the equipment and reduce maintenance and replacement costs.

[0032] Furthermore, it also includes a limiting assembly, which includes a limiting plate and a limiting ring. The limiting ring is fixedly connected to the inner wall of the port of the arc rod, and the limiting plate is fixedly connected to one end of the arc rack located inside the arc rod.

[0033] Beneficial effects: The limit assembly effectively limits the range of movement of the arc-shaped rack in the arc-shaped rod through the use of the limit plate and the limit ring. This design ensures that the arc-shaped rack will not move excessively or fall off when subjected to external force, thereby enhancing the structural stability of the entire restraint device. The addition of the limit assembly further improves the safety of patients during surgery. Even if the patient moves suddenly or struggles, the arc-shaped rack can maintain a stable restraint state, avoiding potential risks caused by falling off.

[0034] Furthermore, the fixing assembly includes a mounting frame, which is a U-shaped structure. The inner wall of the mounting frame is fixedly connected with an anti-slip layer. The mounting plate is detachably connected to one side of the mounting frame. A hole is opened on the other side of the mounting frame, and a locking piece is inserted into the hole.

[0035] Beneficial effects: The U-shaped mounting frame can be firmly inserted into the edge or fixed part of the operating table, fit closely with the surface of the operating table, and is further reinforced by locking parts to ensure that the restraint device will not shake or shift during surgery, providing stable support and restraint for the patient. The U-shaped structure and adjustable locking parts of the mounting frame enable the fixing assembly to adapt to DSA operating tables of different models and sizes, improving the versatility and adaptability of the restraint device. The anti-slip layer fixed on the inner wall of the mounting frame can increase the friction with the surface of the operating table, preventing the mounting frame from sliding or falling off during surgery, further improving the stability and safety of the fixation.

[0036] Furthermore, the locking member includes a locking rod, one end of which is fixedly connected to a handle, and the other end of which is fixedly connected to a suction cup.

[0037] Beneficial effects: The locking rod can be firmly attached to the bottom or side of the DSA operating table through the suction cup fixed at the other end, forming a strong fixing force. This design ensures that the restraint device will not loosen or fall off due to the patient's movement or struggle during the operation, thereby greatly enhancing the stability of the fixation. The design of the handle allows medical staff to easily rotate and push and pull the locking rod, thereby conveniently achieving the adsorption and release of the suction cup. This convenient operation method not only improves work efficiency, but also reduces the workload of medical staff. As part of the locking part, the suction cup has a wide range of adaptability. It can be adsorbed on the surface of operating tables of various materials and shapes, including metal, plastic, glass, etc., so that the restraint device can be applied to DSA operating tables of different brands and models.

[0038] Furthermore, it also includes a remote control module, which is connected to the controller signal. The remote control module is used to input control instructions to the controller. The control instructions include: remotely adjusting the restraint strength of the restraint device, checking the patient's physiological parameters, and controlling the inflation and deflation of the anti-pressure sore component.

[0039] Beneficial effects: The remote control module allows medical staff to remotely adjust the restraint strength of the restraint device by inputting control commands outside the operating room or away from the patient. This design reduces the number of times medical staff enter and exit the operating room, reduces the risk of cross-infection in the operating room, and improves surgical efficiency. In addition, remote control can ensure that medical staff can adjust the restraint strength in a timely manner according to the actual situation of the patient without affecting the surgical operation, thereby ensuring the safety and comfort of the patient. Through the remote control module, medical staff can view the patient's physiological parameters, such as heart rate, blood pressure, respiratory rate, etc. in real time. This real-time monitoring function helps medical staff to detect and deal with abnormal conditions of patients in a timely manner, ensuring the safety and stability of the surgical process. At the same time, the remote control module can also transmit the patient's physiological parameter data to the hospital's information system in real time, which is convenient for subsequent analysis and diagnosis.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The following is further described in detail through specific implementation methods:

[0052] Embodiment 1:

[0053] As attached Figure 1 , Figure 2 and Figure 3 As shown: A limb restraint device for interventional surgery, including a DSA operating table 1 (i.e., a digital subtraction angiography (Digital Subtraction Angiography) operating table), a plurality of fixing components 2 for fixing the restraint device are installed on the top of the DSA operating table 1, and the fixing component 2 in this embodiment is a clamp. The restraint device includes a mounting plate 3, one side of the mounting plate 3 is fixedly connected to the fixing component 2, and the other side of the mounting plate 3 is fixedly connected to an arc rod 4, the arc rod 4 is a hollow structure, and a power part is also fixedly connected to the mounting plate 3, and the power part in this embodiment is a motor 5. The output shaft of the power part passes through the arc rod 4, and the outer wall of the output shaft is sleeved with a gear ring 6, and an arc rack 7 is embedded in the arc rod 4, and the arc rack 7 is meshed with the gear ring 6, and grooves 401 matching the arc rack 7 are provided at both ends of the arc rod 4. A protective layer is fixedly connected to the arc rack 7 close to the patient's skin. It also includes a limiting assembly, which includes a limiting plate and a limiting ring, the limiting ring is fixedly connected to the inner side wall of the port of the arc rod 4, and the limiting plate is fixedly connected to one end of the arc rack 7 located inside the arc rod 4. The limiting assembly helps prevent the arc rack 7 from excessively moving in the arc rod 4, thereby causing it to fall off.

[0054] It also includes a controller and a monitoring component. The monitoring component is used to monitor the patient's status information in real time. The monitoring component and the power part are both connected to the controller signal. The controller issues corresponding instructions to the power part according to the patient's status information fed back by the monitoring component. The monitoring component includes a heart rate monitor, a blood pressure monitor, an electromyographic sensor and a pressure sensor. The heart rate monitor is used to monitor the patient's heart rate changes in real time to determine whether the patient is in a state of tension or anxiety. The blood pressure monitor is used to monitor the patient's blood pressure fluctuations in real time to evaluate the patient's stress response. The electromyographic sensor is used to monitor the patient's muscle micro-activity to determine whether the patient has a struggling movement. The pressure sensor is used to detect the pressure applied by the restraint device to the patient to ensure that the pressure is within a safe range to avoid discomfort or injury to the patient. The heart rate monitor is an electrode sheet, the blood pressure monitor is a cuff-type sphygmomanometer, the electromyographic sensor and the pressure sensor are both installed on the outer wall of the arc rod 4, and the heart rate monitor, the blood pressure monitor, the electromyographic sensor and the pressure sensor are all electrically connected to the controller.

[0055] The struggling state of the status information is manifested as: the heart rate monitored by the heart rate monitor, the heart rate monitored by the blood pressure monitor, the muscle activity detected by the electromyography sensor and the pressure monitored by the pressure sensor all exceed the preset thresholds; the stable state is manifested as: the heart rate monitored by the heart rate monitor, the heart rate monitored by the blood pressure monitor, the muscle activity detected by the electromyography sensor and the pressure monitored by the pressure sensor do not exceed the preset thresholds.

[0056] When the monitoring component detects that the patient is struggling when using the restraint device, the controller sends a tightening command to the power component, causing the power component to drive the arc-shaped rack 7 to move inward along its curvature direction, thereby increasing the restraining force on the patient; when the monitoring component detects that the patient is in a calm state when using the restraint device, the controller sends a relaxation command to the power component, causing the power component to drive the arc-shaped rack 7 to move outward along the curvature direction of the arc-shaped rod 4, thereby reducing the restraining force on the patient.

[0057] In this embodiment, a waist fixator (not shown in the figure) is installed on the DSA operating table 1. The waist fixator is used to fix the upper torso of the patient during the operation. The waist fixator is a strap.

[0058] The specific implementation process is as follows: on the top of the DSA operating table 1, the restraint device is firmly installed on both sides of the two ends of the DSA operating table 1 (4 in total) at a preset position through the fixing component 2 (clamp) in this embodiment to ensure that the mounting plate 3 is stable and immovable.

[0059] Debug the monitoring components to ensure that they can accurately reflect the patient's heart rate, blood pressure, muscle activity, and the pressure applied by the restraint device. That is, the heart rate monitor is attached to the patient's skin through the electrode sheet, the cuff-type blood pressure monitor is fixed to the patient's upper arm through an appropriate binding method, the electromyographic sensor is installed on or near the outer wall of the arc rod 4, and contacts the patient's muscles through the electrode, and the pressure sensor is used to directly measure the pressure applied by the restraint device to the patient. Ensure that the signal connection between all monitoring components and the controller is stable and reliable so as to transmit the patient's status information in real time.

[0060] The controller is connected to the monitoring component and the motor 5 by signal, and the corresponding control parameters and thresholds are set. During the operation, the operating status of the controller and the feedback information of the monitoring component are continuously monitored to ensure that the restraint device is adaptively adjusted according to the actual situation of the patient. The controller automatically adjusts the working state of the power part, thereby changing the position and restraint force of the arc rack 7. For example, when the patient struggles, the controller automatically issues a tightening command; when the patient is detected to be in a stable state, a relaxation command is issued.

[0061] For example, at the beginning of the operation, the controller starts the motor 5. The output shaft of the motor 5 starts to rotate, driving the gear ring 6 connected to it to rotate together. Since the gear ring 6 is meshed with the arc-shaped rack 7, the rotational movement of the gear ring 6 is effectively converted into the linear movement of the arc-shaped rack 7. As the motor 5 continues to rotate, the arc-shaped rack 7 gradually rotates out of the arc-shaped rod 4 along the curvature of the arc-shaped rod 4, and together with the arc-shaped rod 4, forms a clamp structure that firmly clamps the patient's limbs. Figure 1As shown in the figure, the restraint device on the left is used to fix the patient's upper limbs, and the restraint device on the right is used to fix the patient's lower limbs, while the patient's upper torso is fixed with straps. During this process, the pressure sensor continuously monitors and records the pressure applied by the restraint device on the patient to ensure that the pressure is always within a safe range.

[0062] After the operation begins, the heart rate monitor, blood pressure monitor and electromyography sensor in the monitoring component begin to transmit the patient's status data to the controller in real time. The controller compares this data with the preset threshold to determine the patient's current status.

[0063] If the heart rate monitor shows that the patient's heart rate rises sharply, the blood pressure monitor also shows that the blood pressure fluctuates, and the electromyography sensor captures the patient's slight muscle activity, and these data exceed the struggle state threshold preset in the controller, the controller immediately issues a step-up instruction to the motor 5.

[0064] After receiving the command, the motor 5 starts quickly (maintaining the original direction but accelerating the rotation), and the output shaft drives the gear ring 6 to rotate again, thereby driving the arc rack 7 to further rotate out of the arc rod 4 along the curvature of the arc rod 4. The arc rack 7 passes through the groove 401, and the diameter of the clamp structure composed of the arc rack 7 and the arc rod 4 gradually decreases. This process increases the restraining force of the restraint device on the patient, effectively limits the patient's struggling movements, and ensures the smooth progress of the operation.

[0065] Subsequently, under the combined effects of the doctor's comfort and the medication, the patient gradually calmed down. The data from the heart rate monitor, blood pressure monitor, and electromyography sensor also returned to below normal levels, below the threshold of the stable state preset in the controller. Therefore, the controller again issued a relaxation command to the motor 5.

[0066] After receiving the command, the motor 5 starts to rotate (in the opposite direction), and the output shaft drives the gear ring 6 to rotate in the opposite direction, thereby driving the arc-shaped rack 7 to gradually retract into the arc-shaped rod 4 along the curvature of the arc-shaped rod 4. This process gradually reduces the restraining force of the restraint device on the patient, which not only ensures the patient's comfort, but also avoids the possible harm caused by excessive restraint.

[0067] Through this series of adaptive adjustment processes, the restraint device successfully made dynamic adjustments according to the patient's actual condition. This not only ensured the patient's stability and safety during the operation, but also improved the efficiency and success rate of the operation. At the same time, it also reflects the development trend of modern medical technology in terms of humanization and intelligence.

[0069] As attached Figure 4 and Figure 5As shown, the difference from Example 1 is that an anti-pressure sore component is installed on the side wall of the arc rod 4, and the anti-pressure sore component includes a first air bag 8 and a second air bag 9, and the first air bag 8 and the second air bag 9 are both installed on the outer side wall of the arc rod 4, and the first air bag 8 and the second air bag 9 are both provided with an air inlet and an air outlet, and the inlets are connected to an air pump, and the air inlet and the air outlet are both installed with a one-way valve, and the air pump and the one-way valve are both connected to the controller signal, and the controller performs opening and closing command operations on the power part and the one-way valve according to the monitoring data of the monitoring component; the monitoring component also includes a temperature sensor and a humidity sensor, and the temperature sensor and the humidity sensor are both installed on the side of the first air bag 8 and the second air bag 9 close to the skin.

[0070] The device also includes an auxiliary component for alleviating pressure ulcers on the patient's skin. The auxiliary component includes a connecting plate 10, which is fixedly connected to the outer wall of the arc tube between the first airbag 8 and the second airbag 9. A slide plate 11 is slidably fitted on the connecting plate 10. Push plates 12 are fixedly connected at both ends of the slide plate 11. A massage piece 13 is fixedly connected to one side of the push plate 12. In this embodiment, the massage piece 13 is a massage ball.

[0071] The specific implementation process is as follows: when the restraint device restrains the patient's limbs, the air pump is started by the controller, and the air pump inflates the first airbag 8, so that the first airbag 8 expands and fits the patient's limbs to ensure effective contact between the airbag and the skin. When the first airbag 8 is inflated to a preset fullness, the controller closes the one-way valve at the air inlet of the first airbag 8 and stops the operation of the air pump to keep the first airbag 8 in a stable state.

[0072] The temperature sensor and humidity sensor in the monitoring component begin to continuously and in real time monitor the temperature and humidity of the patient's skin. These sensors transmit the collected data to the controller in real time for subsequent analysis and processing. The controller has preset normal threshold ranges for skin temperature and humidity. When the monitoring data shows that the patient's skin temperature is abnormally high due to ischemia, or the skin becomes dry and dehydrated due to long-term restraint, causing the monitoring data to exceed the preset threshold, the controller will immediately determine that the patient may be at risk of pressure sores.

[0073] Once the controller makes such a judgment, it will immediately send a command to another air pump to inflate the second airbag 9. At the same time, the controller will also open the one-way valve at the air outlet of the first airbag 8 to allow the gas in the first airbag 8 to be gradually discharged. In this process, the inflation of the second airbag 9 will gradually increase the pressure inside it, thereby exerting a pushing effect on the push plate 12 on the same side.

[0074] When the push plate 12 is subjected to pressure, it will drive the slide plate 11 to slide smoothly on the connecting plate 10. As the slide plate 11 moves, the push plate 12 at the other end of the slide plate 11 will also appropriately squeeze the first airbag 8, thereby accelerating the exhaust process of the first airbag 8. This design not only ensures the timely replacement of the airbag and the uniform distribution of pressure, but also helps to improve the comfort of the patient.

[0075] At the same time, the massage element 13 (such as a massage ball) installed on the push plate 12 will roll on the patient's skin as the push plate 12 moves. This gentle massage effect not only helps relieve the itching of the skin, but also promotes blood circulation and reduces the risk of pressure sores. Through the rolling massage of the massage element 13, the patient's skin is effectively stimulated and relaxed, thereby improving the overall comfort.

[0076] During the whole process, the controller will continuously receive data feedback from the monitoring components and accurately control the air pump and the one-way valve according to the actual situation. This intelligent control system not only improves the efficiency and accuracy of pressure sore prevention, but also ensures the safety and comfort of patients during the restraint process. The above process can effectively restrain patients and prevent the occurrence of pressure sores. At the same time, with the help of the intelligent control system and the auxiliary role of the massage component, the patient's comfort and treatment effect can be further improved.

[0077] Embodiment 3:

[0078] The difference from Example 2 is that it also includes an early warning module, which is connected to the signal of the monitoring component. When the heart rate monitored by the heart rate monitor, the heart rate monitored by the blood pressure monitor, the muscle activity detected by the electromyography sensor and the pressure monitored by the pressure sensor in the monitoring component exceed the preset safety range, the early warning system is automatically triggered to issue an early warning message to remind medical staff to take measures.

[0079] The specific implementation process is as follows: the various sensors in the monitoring component start working, the heart rate monitor monitors the patient's heart rate changes in real time, the blood pressure monitor continuously measures the patient's blood pressure level, the electromyography sensor captures the tiny electrical signal changes of the patient's muscles to evaluate muscle activity and fatigue, the pressure sensor monitors the pressure distribution between the patient and the restraint device or airbag, and the temperature sensor and humidity sensor monitor the temperature and humidity status of the patient's skin respectively. The physiological parameter data collected by all sensors are transmitted to the controller, and the controller determines in real time whether each physiological parameter exceeds the normal range based on the preset safety range. For example, heart rate is too high or too low, blood pressure rises or falls abnormally, electromyography signals show muscle fatigue or spasm, skin temperature and humidity exceed the normal range, etc., which may be regarded as abnormal physiological states.

[0080] Once an abnormal physiological state is detected, the early warning module will be automatically triggered and send out early warning information through sound and light alarms. The early warning information should include the patient's identity information, the type and value of abnormal physiological parameters, the early warning level (such as level 1, level 2, level 3, etc.) and recommended response measures.

[0081] After receiving the warning information, the medical staff should immediately take appropriate first aid or nursing measures according to the prompt content of the information. For example, for patients with abnormal heart rate or blood pressure, emergency treatment or adjustment of drug dosage may be required immediately; for patients with abnormal skin temperature and humidity, the tightness of the restraint device may be adjusted, skin care may be increased, or the second airbag 9 may be activated for pressure dispersion.

[0082] Embodiment 4:

[0083] As attached Figure 6 As shown, the difference from Example 3 is that the fixing component 2 includes a mounting frame 201, the mounting frame 201 is a U-shaped structure, the inner wall of the mounting frame 201 is fixedly connected with an anti-slip layer, the mounting plate 3 is detachably connected to one side of the mounting frame 201, and the other side of the mounting frame 201 is provided with a hole 202, a locking piece is inserted in the hole 202, and the locking rod 203 is threadedly connected to the hole 202.

[0084] The locking member comprises a locking rod 203 , one end of which is fixedly connected to a handle 204 , and the other end of which is fixedly connected to a suction cup 205 .

[0085] The specific implementation process is as follows: Before the operation begins, first confirm the patient's personal information, especially the height, in order to determine the best placement of the mounting frame 201. According to the patient's height and surgical requirements, place the mounting frame 201 at a suitable position on the DSA operating table 1. Ensure that the U-shaped structure can be snapped into the edge or fixed part of the operating table. Gently press the mounting frame 201 to make it fit with the surface of the operating table, and preliminarily determine its stability.

[0086] Insert the locking rod 203 into the hole 202 on the other side of the mounting frame 201, and ensure that the locking rod 203 can rotate smoothly in the hole 202. Hold the handle 204 and rotate the locking rod 203 clockwise or counterclockwise until the suction cup 205 at the other end of the locking rod 203 is in close contact with the bottom of the DSA operating table 1. Continue to rotate the handle 204 until the locking rod 203 is threadedly connected to the hole 202 and the required locking force is achieved. At this time, the suction cup 205 will be firmly adsorbed on the bottom of the operating table, thereby fixing the restraint device on the DSA operating table 1 through the mounting frame 201. Gently shake the mounting frame 201 to check whether it is firmly fixed on the operating table. If there is any looseness or instability, the position and strength of the locking piece should be readjusted immediately. Fix the restraint device through the mounting frame 201 to ensure that the patient can be safely restrained on the DSA operating table 1.

[0087] Embodiment 5:

[0088] The difference from Example 4 is that it also includes a remote control module, which is connected to the controller signal. The remote control module is used to input control instructions to the controller, and the control instructions include: remotely adjusting the restraint strength of the restraint device, checking the patient's physiological parameters, and controlling the inflation and deflation of the anti-pressure sore component.

[0089] The specific implementation process is as follows:

[0090] Remotely adjust the restraint strength of the restraint device: The medical staff sends an adjustment command to the controller through the remote control module. After receiving the command, the controller adjusts the restraint strength of the restraint device through the motor 5. The restraint device adjusts its tightness according to the command of the controller to adapt to the different needs or conditions of the patient.

[0091] View the patient's physiological parameters: The remote control module is connected to the monitoring components (such as heart rate monitors, blood pressure monitors, etc.) through signals. Medical staff send viewing instructions to the controller through the remote control module. After receiving the instructions, the controller obtains the patient's real-time physiological parameter data from the monitoring components. The remote control module displays the acquired data to medical staff so that they can understand the patient's status in a timely manner.

[0092] Control the inflation and deflation of the pressure sore prevention components: The remote control module is connected to the pressure sore prevention components (such as air bags, massage devices, etc.) by signal. Medical staff send inflation and deflation instructions to the controller through the remote control module. After receiving the instructions, the controller controls the air pump, solenoid valve and other devices to realize the inflation and deflation operations of the pressure sore prevention components. The pressure sore prevention components perform corresponding inflation and deflation actions according to the instructions of the controller to reduce the patient's pressure and improve comfort.

[0093] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
