Dual sequential defibrillation assisted airbag

Abstract

This application relates to the field of cardiac arrest emergency defibrillation and provides a dual sequential defibrillation assistive bag. In response to an emergency inflation start command, it controls an electric air pump to inflate the bag according to a preset support pressure threshold through the air inlet of the neck pillow bag. The neck pillow bag, through a ventilation tube connecting itself to the two axillary support bags, simultaneously delivers gas to the two axillary support bags, causing them to inflate synchronously. If the internal pressure of the bag reaches the preset support pressure threshold, the electric air pump stops inflating, maintaining the bag pressure. The user's upper body is then lifted using the lifting handle, allowing electrodes to be placed on the user's back and cushioning the defibrillation impact. Upon receiving a deflation command indicating completion of the rescue, the electric air pump opens the deflation valve to release the gas from the neck pillow and axillary support bags. Once the internal pressure of the bag drops to normal pressure, the deflation valve closes, completing the operation.

Description

Technical Field

[0001] This application relates to the field of defibrillation technology for emergency treatment of cardiac arrest, and in particular to a dual sequential defibrillation assistive bag. Background Technology

[0002] Dual sequential defibrillation is a common rescue strategy in cardiac arrest emergency care. This procedure requires pre-attaching defibrillation electrodes to the patient's back. Traditionally, multiple medical personnel are needed to manually lift the patient's upper body to expose the electrodes, making the process cumbersome, inefficient, and potentially wasting valuable time. To address these issues, current technologies only disclose the structure of dual sequential defibrillation assistive bags, without proposing automated control schemes suitable for emergency scenarios. Currently, these bags rely entirely on manual inflation and deflation, lacking automatic pressure control and synchronized inflation of all bags. Common problems include prolonged inflation time, insufficient support due to underinflation, and overinflation causing the bags to become too stiff and compress the patient, failing to meet the speed and stability requirements of emergency situations. Summary of the Invention

[0003] This application provides a dual sequential defibrillation assistive bag, which aims to solve the problems that the current dual sequential defibrillation assistive bags still rely entirely on manual inflation and deflation, cannot automatically control the inflation pressure, and cannot automatically ensure that each bag is inflated synchronously. They generally suffer from problems such as long inflation time, insufficient support due to insufficient inflation, and excessive pressure due to over-inflation, which can cause the bag to become too hard and compress the patient. They cannot meet the requirements of operation speed and support stability in emergency scenarios.

[0004] In a first aspect, embodiments of this application provide a method for controlling a dual sequential defibrillation assistive airbag, the method comprising: In response to the emergency inflation start command, the electric air pump is controlled to inflate the airbag through the air inlet of the neck pillow airbag according to the preset support pressure threshold. The neck pillow airbag delivers gas to the two armpit airbags simultaneously through the air tube structure connecting itself to the two armpit airbags, so that the neck pillow airbag and the two armpit airbags expand synchronously. If the internal pressure of the airbag is detected to reach the preset support pressure threshold, the electric air pump is controlled to stop inflating, and the airbag is kept in pressure. The user's upper body is lifted by the lifting handle, and electrodes are placed on the user's back to buffer the defibrillation impact. Upon receiving the deflation command indicating that the rescue is complete, the electric air pump is controlled to open the deflation valve, releasing the gas from inside the neck pillow airbag and armpit airbag. Once the pressure inside the airbag is detected to have dropped to normal pressure, the deflation valve is closed to complete the operation.

[0005] In some embodiments, controlling the electric air pump to inflate the airbag through the air inlet of the neck pillow airbag according to a preset support pressure threshold includes: acquiring patient body shape parameters collected at the emergency scene, calling a pre-trained pressure adaptation model, matching the preset support pressure threshold according to the patient body shape parameters, and controlling the electric air pump to start inflation according to the matched preset support pressure threshold.

[0006] In some embodiments, the neck pillow airbag, through a ventilation tube structure connecting itself to the two axillary support airbags, synchronously delivers gas to the two axillary support airbags, so that the neck pillow airbag and the two axillary support airbags expand synchronously. This includes: during the inflation process, collecting the pressure change rate of the neck pillow airbag and the two axillary support airbags in real time, comparing the pressure change rate difference between the two axillary support airbags, and if the difference exceeds a preset rate threshold, issuing a ventilation tube passage abnormality warning, stopping inflation and waiting for investigation; if the difference does not exceed the preset rate threshold, maintaining the inflation process to ensure synchronous expansion.

[0007] In some embodiments, if the internal pressure of the airbag is detected to reach a preset support pressure threshold, the step of controlling the electric air pump to stop inflating and maintaining the airbag pressure includes: detecting the internal pressure of the airbag once every preset time interval during the pressure holding process; if the pressure drop is detected to exceed a preset leakage pressure threshold, controlling the electric air pump to start supplementary inflation until the pressure returns to the preset support pressure threshold and then stopping inflation again to ensure stable support force.

[0008] In some embodiments, the step of controlling the electric air pump to open the venting valve and release the gas inside the neck pillow airbag and the armpit airbag after receiving the deflation command for the completion of rescue includes: acquiring an image of the airbag untying status collected on site, calling a pre-trained state recognition model to identify and confirm that the airbag has been completely detached from the patient's body, then controlling the opening of the venting valve to start venting, and if it is detected that the airbag is still in contact with the patient's body, issuing an untying prompt and pausing the deflation operation.

[0009] In some embodiments, after detecting that the internal pressure of the airbag has dropped to normal pressure, closing the vent valve to complete the operation includes: after closing the vent valve, detecting the change in airbag pressure under normal pressure within a preset static time; if the change exceeds a preset leakage threshold, generating and storing an airbag leakage maintenance prompt, and simultaneously sending it to the associated device management terminal to complete the operation.

[0010] In some embodiments, the method further includes: during the process of lifting the user under pressure, collecting the pressure change inside the airbag in real time; when it is detected that the pressure drops due to lifting and squeezing beyond a preset adjustment threshold, controlling the electric air pump to supplement a small amount of gas to increase the support pressure, so as to help to stably lift the user's upper body; and automatically adjusting the pressure back to the original preset support pressure threshold after the lifting is completed.

[0011] In some embodiments, the method further includes: during defibrillation, collecting pressure fluctuation data of the airbag in real time, comparing the pressure fluctuation data with a preset impact force threshold, calculating the magnitude of the impact force generated by each defibrillation, generating and storing a defibrillation impact record to assess whether the user has suffered secondary injury.

[0012] In some embodiments, the method further includes: after inflation, acquiring pressure distribution data of the neck pillow airbag and the two side armpit airbags, comparing the pressure distribution data with a preset matching pressure range, and if the local pressure exceeds the range, generating a prompt message to adjust the tightness of the binding, and re-detecting the pressure distribution after adjustment until the pressure distribution meets the requirements, ensuring a comfortable fit and sufficient support.

[0013] Secondly, this application provides a dual-sequential defibrillation assistive bag for performing dual-sequential defibrillation assistive medical work on patients and implementing the method provided in any embodiment of this application, characterized in that the dual-sequential defibrillation assistive bag comprises: The neck pillow airbag has a ring-shaped structure and can be fitted onto the patient's neck. The outer surface of the neck pillow airbag is provided with an air inlet that communicates with the interior. Two axillary support airbags are connected to both sides of the neck pillow airbag and communicate with the inside of the neck pillow airbag. The two axillary support airbags can be wrapped and tied under the patient's armpits. The surface of the two axillary support airbags is also provided with auxiliary handles.

[0014] This application designs a complete automated control process for dual sequential defibrillation assistive bags, which can automatically complete the entire process of inflation, synchronous expansion, pressure holding, and deflation without requiring medical personnel to manually adjust the inflation pressure. It can complete bag preparation in a short time, saving valuable time for cardiac arrest emergency treatment. It can automatically ensure that the neck pillow bag and the two axillary support bags are synchronously inflated and stably maintain the preset support pressure. It not only meets the support requirements for lifting and exposing the back, but also provides stable cushioning support during defibrillation. This simplifies the emergency operation process, reduces the risk of human error, and effectively improves the rescue efficiency of dual sequential defibrillation.

[0025] Dual sequential defibrillation is a common rescue strategy in cardiac arrest emergency care. This procedure requires pre-attaching defibrillation electrodes to the patient's back. Traditionally, multiple medical personnel are needed to manually lift the patient's upper body to expose the electrodes, making the process cumbersome, inefficient, and potentially wasting valuable time. To address these issues, current technologies only disclose the structure of dual sequential defibrillation assistive bags, without proposing automated control schemes suitable for emergency scenarios. Currently, these bags rely entirely on manual inflation and deflation, lacking automatic pressure control and synchronized inflation of all bags. Common problems include prolonged inflation time, insufficient support due to underinflation, and overinflation causing the bags to become too stiff and compress the patient, failing to meet the speed and stability requirements of emergency situations.

[0026] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4 This invention provides a dual-sequential defibrillation support airbag for assisting patients with dual-sequential defibrillation. The dual-sequential defibrillation support airbag includes a neck pillow airbag 100 and two axillary support airbags 200. The neck pillow airbag 100 can be placed around the patient's neck, and its outer surface has an air inlet 140 communicating with its interior. The neck pillow airbag provides flexible support for the patient's neck. The air inlet 140 on the outer surface of the neck pillow airbag 100 allows connection to an external air source for inflation.

[0027] Two axillary airbags 200 are connected to both sides of the neck pillow airbag 100 and communicate with the interior of the neck pillow airbag 100. The two axillary airbags 200 can be wrapped and secured under the patient's armpits. The surfaces of the two axillary airbags 200 are also equipped with auxiliary handles 210. The connection between the two axillary airbags 200 and the neck pillow airbag 100, and their communication with the interior of the neck pillow airbag 100, allows gas to enter the axillary airbags 200 from the neck pillow airbag 100 during inflation, achieving synchronous expansion. The two axillary airbags 200 can be wrapped and secured under the patient's armpits, thus forming flexible support under the patient's armpits. The surfaces of the two axillary airbags 200 are also equipped with auxiliary handles 210 for medical personnel to lift and elevate the patient's upper body.

[0028] With the above structure, medical staff can first place the neck pillow airbag 100 around the patient's neck, and then wrap and bind the two axillary support airbags 200 under the patient's armpits, completing the rapid placement of the airbags. When it is necessary to place the back electrode pads, the operator only needs to pull the auxiliary handle 210 to smoothly lift the patient's upper body, fully exposing the back area. A single person can complete the lifting operation that originally required multiple people, significantly improving the rescue efficiency of sequential defibrillation. At the same time, the inflated neck pillow airbag 100 and axillary support airbags 200 form flexible support under the patient's neck and armpits, isolating the patient's limbs from the ground, rigid stretcher, or bed surface, effectively buffering the impact force generated by the instantaneous muscle tetanic contraction of the electric shock, and reducing the risk of secondary injuries such as joint sprains and skin abrasions. The internal interconnection structure between the airbags allows for single-point inflation and overall expansion, simplifying the operation process and ensuring that all airbags inflate synchronously, providing balanced support.

[0029] To facilitate medical staff in lifting the patient's upper limb using the auxiliary handle 210, in some embodiments, the axillary support airbag 200 is strapped to the patient's armpit with a front facing the patient and a back facing the patient, and the auxiliary handle 210 is located on the front of the axillary support airbag 200. This allows medical staff to naturally exert force outward when pulling the handle, conforming to ergonomic operating habits, facilitating the application of force, and avoiding friction or pressure between the auxiliary handle 210 and the patient's armpit skin, thus improving operational convenience and patient comfort.

[0030] Meanwhile, in this embodiment, the auxiliary handle 210 is made of insulating material, and its two ends are connected to the surface of the axillary support airbag 200 by stitching. The insulating material of the auxiliary handle 210 ensures electrical isolation between the operator's hand and the patient's body during defibrillation, avoiding the risk of electric shock due to accidental contact and ensuring the safety of the rescuer; the stitching connection ensures the connection strength between the handle and the axillary support airbag 200, which can withstand repeated lifting without easily loosening or tearing.

[0031] In some embodiments, one end of the axillary support airbag 200 is provided with a first Velcro strip 220, and the other end is provided with a first loop 230. A first Velcro strip 240 is provided on the side of the axillary support airbag 200 where the first Velcro strip 220 is located. The first Velcro strip 220 passes through the first loop 230 and is then bent and bonded to the first Velcro strip 240. Through the cooperation of the first Velcro strip 220, the first loop 230, and the first Velcro strip 240, the axillary support airbag 200 achieves adjustable wrapping and fixation. In use, the axillary support airbag 200 is wrapped around the patient's armpit once, so that one end of the first Velcro strip 220 passes through the first loop 230 at the other end of the axillary support airbag 200 and then folds back. The first Velcro strip 220 and the first Velcro strip 240 are then bonded together to achieve quick fixation.

[0032] In addition, in some embodiments, the axillary support airbag 200 is also provided with a first quick-release buckle 270. One end of the first quick-release buckle 270 is connected to the axillary support airbag 200 by a strap, and the other end of the first quick-release buckle 270 is provided with a first loop 230. The first Velcro strip 220 passes through the first loop 230 and then bends to adhere to the first Velcro strip 240. With this configuration, the combination of the first quick-release buckle 270 and the first Velcro strip 220 not only allows for flexible adjustment of the tightness of the binding according to the patient's body size, ensuring that the axillary support airbag 200 fits firmly under the armpit without slipping, but also facilitates quick removal during emergency situations.

[0033] Furthermore, in some embodiments, the axillary support airbag 200 is provided with a ventilation tube 250. One end of the ventilation tube 250 communicates with the inner cavity of the axillary support airbag 200, and the other end of the ventilation tube 250 communicates with the inner cavity of the neck pillow airbag 100. The ventilation tube 250 serves as an independent ventilation channel, establishing a stable airflow connection between the neck pillow airbag 100 and the axillary support airbag 200. This avoids ventilation obstruction caused by airbag deformation or pressure, ensuring that gas can be quickly and evenly distributed to each airbag unit during inflation, allowing each airbag to expand synchronously and providing a balanced support and lift effect.

[0034] In this embodiment, the axillary airbag 200 is provided with two covering strips 260. The two ends of the two covering strips 260 in the length direction are respectively sewn to the axillary airbag 200 and the neck pillow airbag 100. The two covering strips 260 cover the ventilation tube 250, and the two ends of the two covering strips 260 in the width direction are sewn together to wrap the ventilation tube 250. The covering strips 260 provide physical wrapping and protection for the ventilation tube 250, preventing damage and air leakage due to pulling, bending, or friction with external hard objects during use. Simultaneously, the covering strips 260 further connect and fix the axillary airbag 200 and the neck pillow airbag 100, enhancing the stability of the overall structure and ensuring that the two axillary airbags 200 maintain their relative position during wearing and lifting, avoiding misalignment of the airbags due to uneven force.

[0035] In some embodiments, the opening end 160 of the neck pillow airbag 100 is located in front of the patient, making it convenient for medical staff to wrap the neck pillow airbag 100 around the patient's neck. Furthermore, a second Velcro strip 110 is provided on one side of the opening end 160, and a second loop 120 is provided at the other end of the opening end 160. A second Velcro strip 130 is provided on the side of the neck pillow airbag 100 where the second Velcro strip 110 is provided. The second Velcro strip 110 passes through the second loop 120 and is then bent and bonded to the second Velcro strip 130. Similarly to the axillary support airbag 200, the neck pillow airbag 100 also has a second quick-release buckle 150. One end of the second quick-release buckle 150 is connected to the neck pillow airbag 100 by a strap, and the other end of the second quick-release buckle 150 has a second loop 120. The second Velcro strip 110 passes through the second loop 120 and is then bent and bonded to the second Velcro strip 130. With this design, the combination of the second quick-release buckle 150 and the second magic hook strip 110 not only allows for flexible adjustment of the tightness of the binding according to the patient's body size, ensuring that the neck pillow airbag 100 fits firmly against the neck without slipping, but also facilitates quick disassembly during emergency treatment.

[0036] In some embodiments, the dual sequential defibrillation assistive bag also includes an electric air pump 300, which is connected to the air inlet 140 via an inflation tube 310. The electric air pump 300 can quickly inflate the neck pillow bag 100 with gas, reaching the predetermined support pressure within seconds. Compared to manual inflation, this significantly shortens preparation time and buys valuable time for emergency treatment. At the same time, the electric air pump 300 ensures stable and controllable inflation pressure, avoiding over-inflation that could make the bag too stiff and affect patient comfort, or under-inflation that could result in insufficient support.

[0037] It should be noted that, in one embodiment, the electric air pump 300 may also be equipped with an intelligent airbag pressure detection function, which can preset the inflation pressure or adjust the amount of air inflated according to the patient's body shape, and detect whether the airbag has reached the preset pressure value, and stop inflating the airbag after reaching the pressure value.

[0038] In some embodiments, the surfaces of the neck pillow airbag 100 and the axillary support airbag 200 are both made of a nylon-TPU coated composite material. The nylon material provides high strength and abrasion resistance, making the airbag less prone to rupture during repeated use and emergency operations; specifically, nylon of grades 70D-210D can be selected. In addition, the TPU (thermoplastic polyurethane) coating gives the airbag good airtightness and flexibility, ensuring long-term pressure retention after inflation and a soft surface feel, providing comfort and no irritation when in contact with the patient's skin. Furthermore, this composite material is easy to clean and disinfect, meeting the hygiene requirements for medical devices.

[0039] The following is a brief description of the usage method of the dual sequential defibrillation assistive airbag in this embodiment: Medical staff will place the neck pillow airbag 100 around the patient's neck, use the second hook strip 110 to pass through the second loop 120 and then fold it back, and stick it to the second hook strip 130, adjusting the tightness to fit securely. Then, wrap the two axillary airbags 200 around the patient's two armpits respectively, so that the first hook strip 220 passes through the first loop 230 and then folds back and is attached to the first hook strip 240. Adjust the tightness until it fits firmly. Then connect the electric air pump 300 to the air inlet 140 through the air inlet pipe 310, start the electric air pump 300 to inflate the neck pillow airbag 100 and the armpit airbag 200, so that the airbags expand to the appropriate hardness. When it is necessary to place the back electrode pads, the medical staff hold the two auxiliary handles 210 with both hands and pull them upwards steadily to lift the patient's upper body and expose the back area. After attaching the back electrode pads, slowly lower the patient to a supine position in preparation for two sequential defibrillation. During defibrillation, the neck pillow airbag 100 and the axillary support airbag 200 form a flexible cushion under the patient's neck and armpits to protect the patient's limbs from impact. After use, open the first quick-release buckle 270, release the armpit airbag 200, open the second quick-release buckle 150, release the neck pillow airbag 100, open the deflation valve of the electric air pump 300 to release the air from the airbag, remove the neck pillow airbag 100 from the patient's neck, clean and store it for later use. Please refer to [link / reference]. Figure 5 This application provides a control method for the provided dual sequential defibrillation assistive airbag, used to control such... Figures 1 to 4The accompanying drawings correspond to the dual sequential defibrillation assistive airbags of any embodiment. It should also be noted that all information involved in the methods provided in this application is extracted with the authorization of the relevant users and in accordance with relevant regulations, and will not infringe on user privacy.

[0040] The provided method includes steps S101 to S103. Details are as follows: Step S101. Responding to the emergency inflation start command, control the electric air pump to inflate the airbag through the air inlet of the neck pillow airbag according to the preset support pressure threshold. The neck pillow airbag delivers gas to the two armpit airbags simultaneously through the ventilation tube structure connecting itself to the two armpit airbags, so that the neck pillow airbag and the two armpit airbags expand synchronously.

[0041] Specifically, this step replaces manual inflation, addressing industry pain points such as time-consuming manual inflation and asynchronous airbag inflation. It enables rapid, controllable, and synchronized inflation in emergency situations, securing the golden window for subsequent patient support and ensuring balanced airbag support. This step is the core of the entire control process, establishing a fully automated inflation logic of command response, constant pressure inflation, and synchronized flow distribution. Utilizing the internal interconnected structure of the airbag (the first air tube of the neck pillow airbag and the axillary support airbag, and the second air tube of the neck pillow double-arc airbag), it achieves single-point air intake and synchronized inflation of the entire airbag, eliminating the need for manual intervention throughout the inflation process. This fundamentally eliminates problems such as speed differences, poor synchronization, and uncontrollable pressure associated with manual inflation.

[0042] After medical staff complete the airbag fitting operation, attach the neck pillow airbag to the patient's neck and tie the two axillary airbags under the patient's armpits respectively, connect the electric air pump to the air inlet of the neck pillow airbag through the air inlet tube, and trigger the emergency inflation start command (the triggering method supports multiple emergency scenario adaptation modes such as physical button, emergency equipment linkage, touch screen terminal command, voice command, etc.).

[0043] Upon receiving the emergency inflation start command, the system immediately retrieves the preset support pressure threshold (a pre-calibrated safety airbag pressure value that meets the patient's upper body support needs) and issues a start command to the electric air pump. The electric air pump immediately starts, inflating high-pressure gas into the neck pillow airbag cavity through the air inlet. During inflation, gas is simultaneously delivered into the cavities of the axillary support airbags through the first vent tube between the neck pillow airbag and the axillary support airbags on both sides; at the same time, the two arc-shaped airbags are simultaneously inflated through the second vent tube inside the neck pillow airbag, ultimately achieving synchronous and uniform expansion of the neck pillow airbag and the axillary support airbags on both sides, maintaining a stable airflow throughout the process, and ensuring that each airbag unit reaches the target inflation level simultaneously.

[0044] Step S102. If the internal pressure of the airbag is detected to reach the preset support pressure threshold, control the electric air pump to stop inflating, maintain the airbag pressure, lift the user's upper body with the lifting handle, place the electrodes on the user's back and buffer the defibrillation impact.

[0045] Specifically, this step achieves precise closed-loop control of the inflation endpoint, stably maintaining the rated support pressure of the cuff throughout the entire rescue cycle. This ensures sufficient and balanced support force when lifting the patient, while also providing stable and flexible cushioning during defibrillation, resolving issues such as uncontrolled manual inflation pressure, poor pressure holding capacity, and unstable support effects. This step is the core of pressure holding control and functional support after inflation, establishing a pressure control logic of closed-loop pressure detection, inflation start / stop control, and steady-state pressure maintenance. The internal pressure is monitored in real time by a pressure sensor built into the cuff, enabling precise stopping of inflation. Simultaneously, the cuff is maintained in a sealed, pressure-holding state throughout the rescue process, providing stable physical support for lifting the patient's upper body, attaching back electrodes, and cushioning the defibrillation impact, ensuring balanced and stable support force throughout.

[0046] During inflation, the control system collects the overall pressure data inside the airbag in real time through the pressure sensor built into the airbag, and continuously compares the real-time pressure value with the preset support pressure threshold. When the real-time pressure inside the airbag is detected to reach the preset support pressure threshold, the control system immediately sends a stop inflation command to the electric air pump. The electric air pump immediately stops and closes the air circuit valve, so that the neck pillow airbag and the armpit airbag enter a sealed pressure-maintaining state.

[0047] When under pressure, medical staff can smoothly lift the patient's upper body using the insulated auxiliary handle on the front of the axillary support airbag, fully exposing the area for electrode attachment on the patient's back. This allows a single person to complete the lifting and electrode attachment procedures that previously required multiple people, significantly improving rescue efficiency. After the back electrode attachment is completed and the patient returns to a supine position, the pressure-maintaining airbag forms a continuous, flexible support and buffer layer under the patient's neck and armpits. During defibrillation and muscle tetany, the airbag effectively buffers the impact load, reducing the risk of secondary injuries such as joint sprains and skin abrasions. Throughout the entire rescue process, the airbag maintains its rated pressure, ensuring stable support and buffering effects.

[0048] Step S103. After receiving the deflation command indicating that the rescue is complete, control the electric air pump to open the deflation valve, release the gas inside the neck pillow airbag and the armpit airbag, and close the deflation valve after detecting that the pressure inside the airbag has dropped to normal pressure to complete the operation.

[0049] Specifically, this step aims to automate and ensure safe venting operations after the rescue is completed, standardize the venting process, avoid the risk of misoperation, and at the same time complete the basic confirmation of the equipment status, realize closed-loop control of the entire rescue process, and replace the non-standard operation of manual venting.

[0050] This step is the core of the deflation control and process closed loop at the end of the rescue operation, establishing a deflation control logic of command verification, safe deflation, status confirmation, and process closed loop. Real-time pressure monitoring enables accurate identification of the deflation endpoint, standardizes the deflation operation process, avoids the risk of misoperation during deflation, and automates the entire process of airbag inflation, pressure holding, and deflation.

[0051] Once the two-sequential defibrillation procedure is completed, the medical staff sends a deflation command to the control system to indicate that the procedure is complete. Upon receiving the command, the control system enters the deflation preparation process.

[0052] The control system sends valve control commands to the electric air pump, opening its deflation valve to allow high-pressure gas inside the neck pillow and armpit airbags to be quickly released through the inlet, inflation tube, and deflation valve. During deflation, the control system continuously monitors the pressure drop by collecting real-time pressure data from the airbags using pressure sensors. When the internal pressure of the airbags drops to normal atmospheric pressure, the control system immediately sends a command to the electric air pump to close the deflation valve, completing the entire process of airbag inflation, pressure holding, and deflation. Medical staff can then disassemble, clean, and store the airbags.

[0053] In some embodiments, controlling the electric air pump to inflate the airbag through the air inlet of the neck pillow airbag according to a preset support pressure threshold includes: acquiring patient body shape parameters collected at the emergency scene, calling a pre-trained pressure adaptation model, matching the preset support pressure threshold according to the patient body shape parameters, and controlling the electric air pump to start inflation according to the matched preset support pressure threshold.

[0054] The fixed preset pressure threshold cannot be adapted to patients of different body types (weight, height, body fat percentage, etc.). It is easy to cause problems such as insufficient inflation and insufficient support for larger patients, or over-inflation and pressure discomfort for smaller patients. It cannot balance the support effect and patient safety.

[0055] In the inflation control stage of S101, patient body shape parameter acquisition and intelligent matching logic are introduced. Through a pre-trained pressure adaptation model, the correspondence between patient body shape and optimal support pressure threshold is established, realizing personalized and adaptive matching of inflation pressure, replacing the fixed threshold inflation mode, and taking into account the support needs and physiological safety of different patients.

[0056] Before inflation is started, the control system obtains the patient's core body shape parameters, including but not limited to weight, height, chest circumference, and body fat percentage, through the data collection equipment at the emergency site (emergency monitor body shape acquisition module, on-site camera image recognition module, medical staff manual input terminal, etc.).

[0057] The control system calls the locally pre-trained pressure adaptation model (this model is trained based on a large amount of clinical emergency data, and marks the optimal safe support pressure threshold corresponding to different body shape parameters, taking into account both the support force and the patient's physiological safety). The collected patient body shape parameters are input into the model, and after the model calculates and matches, it outputs the personalized preset support pressure threshold adapted to the patient.

[0058] The control system controls the electric air pump to start inflation according to the personalized threshold obtained by model matching, so that the final inflation pressure of the airbag is perfectly adapted to the individual patient's condition, ensuring the support strength required for lifting while avoiding over-inflation that could cause pressure on the patient's neck and armpits.

[0059] In some embodiments, the neck pillow airbag, through a ventilation tube structure connecting itself to the two axillary support airbags, synchronously delivers gas to the two axillary support airbags, so that the neck pillow airbag and the two axillary support airbags expand synchronously. This includes: during the inflation process, collecting the pressure change rate of the neck pillow airbag and the two axillary support airbags in real time, comparing the pressure change rate difference between the two axillary support airbags, and if the difference exceeds a preset rate threshold, issuing a ventilation tube passage abnormality warning, stopping inflation and waiting for investigation; if the difference does not exceed the preset rate threshold, maintaining the inflation process to ensure synchronous expansion.

[0060] During inflation, if the ventilation tubing becomes bent, blocked, or leaks, it can lead to asynchronous inflation and uneven pressure of the axillary support airbags on both sides. This can cause imbalance of force and upper body tilting when lifting the patient, and even increase the risk of cervical spine and limb injuries. The S101's synchronous inflation process incorporates a real-time comparison mechanism of the pressure change rate of both axillary support airbags. By monitoring the consistency of the inflation rate of both airbags, it determines the patency of the ventilation tubing and the synchronous expansion of the airbags. Abnormalities trigger timely warnings and shutdown, ensuring synchronous inflation of both airbags and balanced lifting force.

[0061] During the entire inflation process, the control system collects real-time pressure data of the three airbags through pressure sensors built into the neck pillow airbag, left axillary support airbag, and right axillary support airbag respectively, at a preset high-frequency acquisition frequency (such as 10Hz / time), and calculates the pressure change rate (pressure rise value per unit time) of the left and right axillary support airbags respectively.

[0062] The control system continuously compares the pressure change rate difference between the two axillary support airbags, and simultaneously presets a rate threshold (this threshold is the maximum rate difference clinically calibrated that does not affect the synchronous support effect, such as 5%). If the difference exceeds the preset rate threshold, it is determined that there is an abnormality such as bend, blockage, or air leakage in the ventilation tubing; if the difference does not exceed the preset rate threshold, it is determined that the synchronous inflation state is normal.

[0063] When an abnormality is detected in the airway, the control system immediately issues an abnormality warning for the airway (audio-visual alarm, pop-up notification on the emergency equipment terminal, etc.) and simultaneously stops the electric air pump from inflating, waiting for medical personnel to investigate the abnormality to avoid safety risks caused by airbag imbalance; when the condition is detected as normal, the normal inflation process is maintained until the preset support pressure threshold is reached.

[0064] In some embodiments, if the internal pressure of the airbag is detected to reach a preset support pressure threshold, the step of controlling the electric air pump to stop inflating and maintaining the airbag pressure includes: detecting the internal pressure of the airbag once every preset time interval during the pressure holding process; if the pressure drop is detected to exceed a preset leakage pressure threshold, controlling the electric air pump to start supplementary inflation until the pressure returns to the preset support pressure threshold and then stopping inflation again to ensure stable support force.

[0065] During the pressure-holding process, the airbag may experience a drop in pressure due to minor material leakage, slight air leakage at the pipe interface, or compression by the patient's limbs, resulting in insufficient support, affecting the lifting operation and cushioning effect, and making it impossible to maintain stable support for a long time.

[0066] In the pressure holding stage of S102, a periodic pressure inspection and automatic pressure replenishment mechanism is introduced. Through intermittent pressure detection, the pressure drop of the airbag is identified. When the pressure leakage exceeds the safe range, supplementary inflation is automatically started to restore the pressure to the rated threshold, maintaining the stability of the airbag support force throughout the process.

[0067] After the airbag enters the pressure-holding state, the control system starts the periodic pressure inspection mode, and detects the overall pressure data inside the airbag once through the pressure sensor according to the preset interval (such as 2 seconds / time, which can be adjusted according to the emergency scenario).

[0068] After each test, the real-time pressure value is compared with the preset support pressure threshold to calculate the pressure drop. At the same time, a preset leakage threshold is set (this threshold is the calibrated maximum pressure drop that does not affect the support effect, such as 10% of the rated threshold). If the detected pressure drop exceeds the preset leakage threshold, it is determined that the pressure leakage exceeds the safe range, and the electric air pump is immediately controlled to start supplementing air.

[0069] During the inflation process, the pressure recovery status of the airbag is monitored in real time. When the internal pressure of the airbag is detected to return to the preset support pressure threshold, the electric air pump is immediately controlled to stop the inflation and restore the sealed pressure-holding state. This achieves closed-loop pressure control throughout the pressure-holding process, ensuring that the airbag's support force always meets the rescue requirements.

[0070] In some embodiments, the step of controlling the electric air pump to open the venting valve and release the gas inside the neck pillow airbag and the armpit airbag after receiving the deflation command for the completion of rescue includes: acquiring an image of the airbag untying status collected on site, calling a pre-trained state recognition model to identify and confirm that the airbag has been completely detached from the patient's body, then controlling the opening of the venting valve to start venting, and if it is detected that the airbag is still in contact with the patient's body, issuing an untying prompt and pausing the deflation operation.

[0071] If the airbag is deflated prematurely before it is completely detached from the patient's body, the rapid contraction of the airbag may entangle or impinge on the patient's limbs, or cause abnormal patient positioning, posing a safety hazard. At the same time, it is impossible to avoid accidental deflation caused by accidentally triggering the deflation command, which will affect the rescue process.

[0072] In the S103 deflation control process, an intelligent verification mechanism for the untying status of the airbag before deflation is introduced. The image recognition model determines whether the airbag has completely detached from the patient's body. The deflation operation is only started after it is confirmed that the airbag is completely untying. If it is not untying, a prompt is triggered and the deflation is paused, thus avoiding safety risks in the deflation process.

[0073] After receiving the deflation command indicating that the rescue is complete, the control system does not immediately open the deflation valve. Instead, it first triggers the image acquisition equipment (such as cameras at the emergency site or vision modules mounted on the emergency cart) to acquire images of the airbag's untying status at the scene.

[0074] The control system calls the pre-trained state recognition model (which is trained based on a large amount of image data of airbag wearing and untying, and can accurately identify the contact and binding status between the airbag and the patient's body), inputs the collected images into the model, and identifies and confirms whether the airbag has been completely removed from the patient's body and whether all binding structures have been untied.

[0075] If the model confirms that the airbag has been completely detached from the patient's body, the control system will then send a command to the electric inflation pump to open the deflation valve and begin the normal deflation operation. If the model detects that the airbag is still in contact with the patient's body and is still in a bound state, it will immediately issue a debinding prompt (audio-visual alarm, terminal pop-up prompt), and at the same time suspend the deflation operation, waiting for medical staff to complete the unbinding of the airbag before re-verifying the status and performing the deflation operation.

[0076] In some embodiments, after detecting that the internal pressure of the airbag has dropped to normal pressure, closing the vent valve to complete the operation includes: after closing the vent valve, detecting the change in airbag pressure under normal pressure within a preset static time; if the change exceeds a preset leakage threshold, generating and storing an airbag leakage maintenance prompt, and simultaneously sending it to the associated device management terminal to complete the operation.

[0077] If minor leaks or damage occur after the airbag has been used, and these issues are not detected in time, it can lead to problems such as inflatability failure and insufficient support during the next emergency use, affecting the effectiveness of emergency treatment and making it impossible to achieve full life cycle management of the equipment.

[0078] In the final stage of the S103 deflation process, a self-check mechanism for air tightness of the airbag under normal pressure is introduced. By monitoring the pressure change of the airbag under static conditions, it can determine whether there is any leakage or damage to the airbag. If an abnormality is detected, a maintenance prompt is generated and synchronized to the management terminal, so as to realize early detection and early handling of equipment failures and ensure that the equipment is always in an available state.

[0079] After the control system detects that the internal pressure of the airbag has dropped to normal pressure and closes the deflation valve, it immediately starts the airbag airtightness self-test program, controls the air circuit valve to close, and forms a sealed normal pressure cavity inside the airbag.

[0080] Within a preset resting time (e.g., 30 seconds), the control system continuously collects pressure data inside the airbag through pressure sensors and counts the pressure change during the resting time; at the same time, a preset leakage threshold is set (this threshold is the maximum pressure fluctuation value calibrated under normal airbag conditions); if the pressure change exceeds the preset leakage threshold, it is determined that the airbag has a leakage or rupture fault.

[0081] When an airbag malfunction is detected, the control system immediately generates an airbag leakage maintenance prompt. At the same time, it stores the self-test data and fault prompt information to the local device and sends them to the associated equipment management terminal (hospital emergency equipment management platform, emergency center operation and maintenance terminal, etc.) to remind operation and maintenance personnel to inspect, maintain or replace the airbag in a timely manner. If the airtightness is normal, the entire process is completed and the equipment enters standby mode.

[0082] In some embodiments, the method further includes: during the process of lifting the user under pressure, collecting the pressure change inside the airbag in real time; when it is detected that the pressure drops due to lifting and squeezing beyond a preset adjustment threshold, controlling the electric air pump to supplement a small amount of gas to increase the support pressure, so as to help to stably lift the user's upper body; and automatically adjusting the pressure back to the original preset support pressure threshold after the lifting is completed.

[0083] When medical staff lift a patient’s upper body, the patient’s weight will compress the airbag, causing the airbag pressure to drop, the deformation to be too large, and the support to be insufficient. This can easily lead to unstable lifting and the risk of the patient slipping, and cannot provide dynamic support for the lifting operation.

[0084] In the pressure-holding phase of S102, a new real-time pressure monitoring and adaptive adjustment mechanism has been added during the lifting process. It can identify abnormal drops in airbag pressure caused by the lifting operation, automatically replenish gas to increase support, and automatically return to the rated pressure after the lifting is completed, taking into account both the stability of the lifting operation and the comfort of the patient when lying flat.

[0085] When the airbag is in a pressurized state, the control system continuously collects pressure change data inside the airbag in real time through a pressure sensor at a high frequency. When medical staff lift the patient's upper body, the patient's weight compresses the airbag, causing an abnormal drop in pressure. The control system captures this pressure change in real time and compares the pressure drop with a preset adjustment threshold (a calibrated critical value for normal pressure drop caused by lifting operations, such as 15% of the rated threshold).

[0086] When the pressure drops below the preset adjustment threshold due to lifting and squeezing, the control system immediately starts the electric air pump to add a small amount of gas into the airbag, slightly increasing the internal pressure of the airbag, enhancing the airbag's support rigidity, counteracting the deformation caused by the patient's weight, assisting medical staff in steadily lifting the patient's upper body, and preventing unstable lifting caused by airbag collapse.

[0087] Once the control system detects the completion of the lifting operation and the patient's return to a supine position (pressure rising back to near the original rated threshold) through pressure changes, it automatically controls the electric air pump to release a small amount of air, restoring the internal pressure of the airbag to the original preset support pressure threshold and resuming normal pressure maintenance, thus preventing excessive pressure from causing compression on the patient's neck and armpits when lying down.

[0088] In some embodiments, the method further includes: during defibrillation, collecting pressure fluctuation data of the airbag in real time, comparing the pressure fluctuation data with a preset impact force threshold, calculating the magnitude of the impact force generated by each defibrillation, generating and storing a defibrillation impact record to assess whether the user has suffered secondary injury.

[0089] The impact force generated by the rigid contraction of the patient's muscles during defibrillation cannot be quantified, it is impossible to assess whether the patient has suffered secondary injury, and it cannot provide data support for subsequent diagnosis and treatment. There is a lack of a traceable impact monitoring mechanism.

[0090] In the S102 defibrillation process, a new real-time monitoring and recording mechanism for defibrillation impact has been added. The impact force generated by defibrillation is quantified by the pressure fluctuation data of the airbag, and the impact intensity is statistically analyzed after being compared with a preset threshold. This generates a traceable defibrillation impact record, providing objective data support for secondary injury assessment of patients.

[0091] With the patient lying flat and in preparation for defibrillation, the control system activates the impact monitoring mode, which uses a high-frequency pressure sensor built into the airbag to collect real-time pressure fluctuation data of the airbag.

[0092] When the defibrillator discharges and the patient's muscles contract rigidly, the impact force of the limb is transmitted to the airbag, causing a sudden and violent fluctuation in pressure. The control system captures this pressure fluctuation data in real time and compares it with a preset impact force threshold (the pressure fluctuation value corresponding to the critical impact force that may cause joint sprains or soft tissue damage in patients, based on clinical data). At the same time, it counts the peak pressure fluctuation generated by each defibrillation discharge and converts it into the corresponding impact force magnitude.

[0093] The system generates a defibrillation impact record that includes the number of defibrillations, the peak value of each impact, the duration of each impact, and whether it exceeds the safety threshold. This record is stored on a local device and can be synchronized to emergency monitors and the hospital's electronic medical record system. Medical staff can use this record to objectively assess the impact intensity experienced by the patient during defibrillation, determine whether the patient is at risk of secondary injury, and provide data for subsequent diagnosis and treatment.

[0094] In some embodiments, the method further includes: after inflation, acquiring pressure distribution data of the neck pillow airbag and the two side armpit airbags, comparing the pressure distribution data with a preset matching pressure range, and if the local pressure exceeds the range, generating a prompt message to adjust the tightness of the binding, and re-detecting the pressure distribution after adjustment until the pressure distribution meets the requirements, ensuring a comfortable fit and sufficient support.

[0095] If the airbag is too loose, it may slip off and provide insufficient support. If it is too tight, it may cause excessive local pressure and compress the patient's blood vessels and nerves. It may also prevent the timely detection of improper wear and pose a dual risk of patient discomfort and support failure.

[0096] After the S102 is fully inflated and enters the pressure holding state, a new airbag pressure distribution verification mechanism is added. By collecting pressure data from multiple points, the pressure at each point is compared with the preset adaptation range to identify local pressure abnormalities and generate corresponding strap tightness adjustment prompts to ensure that the airbag fits snugly, provides balanced support, and does not cause excessive pressure.

[0097] After inflation is complete and the airbag reaches the preset support pressure threshold, the control system acquires full-point pressure distribution data of the neck pillow airbag and the two armpit airbags through multiple pressure acquisition points built into the left and right sides of the neck pillow airbag and the two armpit airbags respectively.

[0098] The control system has preset appropriate pressure ranges for each collection point (clinically calibrated, a safe pressure range that ensures support and fit without causing excessive pressure on the patient). The measured pressure data of each point is compared with the corresponding preset appropriate pressure range one by one. If the pressure of a certain local point exceeds the appropriate range, it is judged as an abnormal fit (too high pressure corresponds to too tight binding, too low pressure corresponds to too loose binding and poor fit).

[0099] When an abnormality is detected, the control system immediately generates a prompt message to adjust the tightness of the strap. The system clearly informs the location of the pressure abnormality and the direction of adjustment through audio-visual prompts and terminal pop-ups. After the medical staff completes the adjustment according to the prompts, the control system re-detects the pressure distribution of the airbag at all points until the pressure distribution at all points meets the requirements of the preset fitting pressure range. This completes the final wearing verification, ensuring that the airbag fits securely, provides balanced support, and eliminates the risk of excessive local pressure.

If the system detects that the airbag is still in contact with the patient's body, it issues an untethering prompt and pauses the deflation operation.

6. The method according to claim 1, characterized in that, After detecting that the internal pressure of the airbag has dropped to normal pressure, the deflation valve is closed to complete the operation, including: After closing the vent valve, the change in airbag pressure under normal pressure within a preset static time is detected. If the change exceeds the preset leakage threshold, an airbag leakage maintenance prompt is generated and stored, and simultaneously sent to the associated equipment management terminal to complete the operation.

7. The method according to claim 1, characterized in that, The method further includes: During the lifting process while maintaining pressure, the pressure changes inside the airbag are collected in real time. When the pressure drops below the preset adjustment threshold due to the lifting and squeezing, the electric air pump is controlled to add a small amount of gas to increase the support pressure, so as to help to steadily lift the user's upper body. After the lifting is completed, the pressure is automatically adjusted back to the original preset support pressure threshold.

8. The method according to claim 1, characterized in that, The method further includes: During defibrillation, pressure fluctuation data of the airbag is collected in real time. The pressure fluctuation data is compared with a preset impact force threshold, and the magnitude of the impact force generated by each defibrillation is calculated. A defibrillation impact record is generated and stored to assess whether the user has suffered secondary injury.

9. The method according to claim 1, characterized in that, The method further includes: After inflation, the pressure distribution data of the neck pillow airbag and the two armpit airbags are obtained and compared with the preset matching pressure range. If the local pressure exceeds the range, a prompt message is generated to adjust the tightness of the binding. After adjustment, the pressure distribution is re-tested until the pressure distribution meets the requirements, ensuring a comfortable fit and sufficient support.

10. A dual-sequential defibrillation assistive bag for performing dual-sequential defibrillation assistive medical procedures on a patient and implementing the method as described in any one of claims 1-9, characterized in that, The dual sequential defibrillation assistive airbag includes: The neck pillow airbag has a ring-shaped structure and can be fitted onto the patient's neck. The outer surface of the neck pillow airbag is provided with an air inlet that communicates with the interior. Two axillary support airbags are connected to both sides of the neck pillow airbag and communicate with the inside of the neck pillow airbag. The two axillary support airbags can be wrapped and tied under the patient's armpits. The surface of the two axillary support airbags is also provided with auxiliary handles.
