Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an airway opening device for assisting in resuscitation posture. Background Art

[0002] During the first aid process, it is crucial to ensure that the patient's airway is open. As a key measure, the resuscitation position is designed to ensure the openness of the airway through a specific body posture, prevent vomitus or secretions from being accidentally inhaled into the lungs, and provide a favorable operating environment for medical staff to implement various first aid procedures. Specifically, the resuscitation position usually requires the patient to lie on his side with his head slightly tilted back to maximize the openness of the airway.

[0003] The traditional method of resuscitation position adjustment mainly relies on manual operation by medical staff. The specific steps are as follows: Assess the patient's condition: Medical staff must first quickly determine the patient's consciousness, breathing and heartbeat. For patients who are unconscious, without spontaneous breathing or whose heart has stopped beating, the resuscitation process must be started immediately.

[0004] Positioning: Gently turn the patient to a side-lying position, usually the right side, to use gravity to help the fluid in the mouth flow out and prevent it from flowing into the trachea.

[0005] Adjust the head position: Open the airway by placing one hand on the patient's forehead and pushing it back, and using the other hand to support the chin and lift it up, so that the head is tilted back slightly.

[0006] Check the airway: Clear any visible foreign matter or secretions from the mouth and throat and ensure the airway is completely open.

[0007] Prepare for intubation: Prepare the instruments required for tracheal intubation, such as laryngoscope, tracheal tube, etc., so as to carry out the next step of artificial ventilation.

[0008] Endotracheal intubation (if necessary): This procedure involves using a laryngoscope to expose the glottis, then inserting an endotracheal tube into the trachea, securing the tube after it is properly positioned, and connecting it to a ventilator to begin artificial ventilation In emergency medical situations, manually adjusting the patient's head position often takes valuable time and may take multiple attempts to achieve the ideal position. This situation not only delays critical treatment time and increases the risk faced by patients, but every second of delay may have an adverse effect on the patient's ultimate recovery. Especially when performing airway management, if the patient needs to be placed in the resuscitation position and intubated, the current main reliance on the experience of medical staff is to adjust the patient's head tilt angle. However, due to differences in experience between different medical staff, this may result in inaccurate or unstable head tilt angles, which may affect the smooth progress of the intubation operation and may even cause additional harm to the patient.

[0009] Therefore, it is urgent to develop an auxiliary resuscitation position airway opening device to solve the above-mentioned technical problems. Summary of the invention

[0010] The purpose of the present invention is to provide an airway opening device for assisting resuscitation posture, so as to solve the technical problem that the prior art currently mainly relies on the experience of medical staff to adjust the patient's head tilting angle, which may cause the head tilting angle to be inaccurate or unstable, thereby affecting the smooth progress of the intubation operation. The preferred technical solutions among the many technical solutions provided by the present invention can produce many technical effects as described below.

[0011] To achieve the above object, the present invention provides the following technical solutions: The present invention provides an auxiliary resuscitation position airway opening device, comprising: The trunk support plate is used to support the patient's upper limb trunk; A flap is used to support the patient's head. The flap is rotatably arranged on the top of the body support plate to support the patient's head and tilt it back at the neck to open the patient's airway. A driving assembly is fixedly arranged on the body support plate, and is used to drive the flap to flip backward from the top of the body support plate to drive the patient's head supported on the flap to tilt backward, thereby assisting in opening the patient's airway; The fixing component is fixedly installed on the flap and is used to fix and restrict the patient's head on the flap to ensure that the head remains stable during the backward tilt process; An ultrasonic imager comprises a detector mounted on a body support plate and an imager for receiving the detector, wherein the detector is used to detect the open state of the patient's airway, and the imager is used to display the open state of the patient's airway.

[0013] Furthermore, the fixing assembly includes a limiter for limiting excessive flipping of the two splints. When the splints are not used to assist the patient in flipping to open the airway, the limiter is also used to limit the flipping of the splint in the unflipped state.

[0014] Further, the limiting member is a baffle slidably arranged on the flap, the sliding direction of the baffle is perpendicular to the flap plane on which the patient's head is placed, and the two opposite side walls of the baffle are blocking surfaces, the blocking surfaces are perpendicular to the rotation axis of the flap, the clamping plate is centered on the rotation axis, and the side contacting the patient is divided into a placement surface for placing and supporting the head and a clamping surface for clamping the patient's cheek, and the placement surfaces of the two clamping plates are close to each other; When the baffle plate flips around the rotation axis, the two flipping surfaces are arranged in opposite directions along with the flipping, the baffle plate is pulled out along a plane perpendicular to the flap, and the blocking surface abuts against the side wall of the clamping surface to limit excessive flipping of the clamp plate.

[0015] Furthermore, the fixing assembly also includes sliders arranged at both ends of each rotating shaft and springs arranged correspondingly on each slider. A rotating cavity for accommodating the flipping of the two clamps is opened through the flap. A sliding groove with an opening located on the side wall of the rotating cavity is opened on the flap. There are four sliding grooves, and each group of two is symmetrically arranged to accommodate the sliders at both ends of the rotating shaft. The slider is slidably set in the sliding groove, and the spring is set on the side wall of the sliding groove and away from the side wall of the slider in the same sliding direction.

[0016] Further, the limiting member is a baffle plate slidably arranged on the flap, the sliding direction of the baffle plate is perpendicular to the plane of the flap plate on which the patient's head is placed, the baffle plate is provided with a positioning surface for limiting the fixation of the splint in an unflipped state, the positioning surface is arranged on the side of the baffle plate facing the flap plate contacting the patient's head, and the length direction of the baffle plate extends from the midline of the flap plate to the rotation axis of the two splint plates; The splint is centered on the rotation axis, and the side contacting the patient is divided into a placement surface for placing and supporting the head and a clamping surface for clamping the patient's cheek, and the placement surfaces of the two splints are close to each other; When the splint is not in use, the positioning surface is pressed on the placement surface from the middle of the two splints and is pressed on the clamping surface across the axis of the splint to prevent the splint from turning over.

[0017] Furthermore, the limiting member is a baffle slidably set on the flap, the sliding direction of the baffle is perpendicular to the plane of the flap placed on the patient's head, the baffle is used to support the top of the patient's head when assisting the patient to open the airway, and a guide component for guiding the sliding of the baffle is provided on the flap.

[0018] Furthermore, the guide assembly includes a skateboard and a magnetic block, the flap is provided with a guide groove for the sliding of the skateboard, the baffle is fixedly connected to the top of the skateboard, the flap is also provided with a positioning groove, the bottom of the positioning groove is provided with an iron sheet, the magnetic block is fixedly connected to the side wall of the skateboard, and when the baffle is pulled out, the magnetic block slides in the positioning groove and is magnetically attracted to the iron sheet to fix the skateboard and the baffle.

[0019] Furthermore, it also includes a processor and a pressure sensor installed on the body support board, the processor is electrically connected to the pressure sensor, the processor is used to receive and display data transmitted by the pressure sensor, and the pressure sensor is arranged on the top surface of the body support board to contact the patient's back, so as to detect the pressure data of the patient during the compression process when the patient is undergoing cardiopulmonary resuscitation.

[0020] Furthermore, the trunk support plate is used to support the patient's waist and is provided with an inclined surface, and an arc surface is provided at the connection between the inclined surface and the horizontal top surface of the trunk support plate.

[0021] The present invention drives the flap to flip backward from the top of the body support plate through a driving component, and can accurately control the tilt angle of the patient's head. Compared with the traditional manual adjustment method, the present invention can ensure that the ideal tilt angle is achieved every time the operation is performed, avoiding problems such as intubation difficulties or cervical spine injuries caused by inaccurate angles.

[0022] Precisely control the tilt angle Due to the precise control of the drive assembly, different medical staff can obtain a consistent reclining angle when using the device, eliminating the uncertainty caused by differences in personal experience and improving the consistency and reliability of the operation.

[0023] Maintain a stable position The fixation component is fixedly installed on the flap, which can effectively fix and restrict the patient's head, ensuring that the head remains stable during the backward tilt process. This not only improves the success rate of intubation, but also reduces the difficulty of operation and the extension of emergency time caused by head movement.

[0024] Reduce accidental movement In an emergency, the patient's involuntary movements or improper operation by medical staff may cause the head position to change. The fixing assembly of the present invention effectively prevents this from happening, ensuring the safety and stability of the entire operation process.

[0025] Shorten operation time Through the synergistic effect of the driving component and the fixing component, the patient's head can be tilted back and fixed in a short time, greatly shortening the operation time. This is particularly important in the emergency treatment process, which can buy precious treatment time for the patient and improve the survival rate and prognosis quality.

[0026] Reduce duplication of work Due to the precise angle control and strong body position stability, the present invention reduces the number of repeated attempts caused by improper operation, further shortens the operation time, and improves the first aid efficiency.

[0027] Reduce secondary damage By precisely controlling the reclining angle and maintaining a stable body position, the present invention significantly reduces the risk of secondary injury caused by unsuccessful intubation. The use of an ultrasonic imager further ensures the visualization of the airway opening state, helping medical staff to adjust the operation in time and avoid damage to the throat tissue.

[0028] Improved safety Ultrasound imaging can monitor the opening status of the patient's airway in real time and provide intuitive image feedback, enabling medical staff to more accurately determine whether the airway is fully open, thereby improving the safety and success rate of intubation operations.

[0029] In summary, the assisted resuscitation position airway opening device of the present invention significantly improves the success rate and safety of tracheal intubation by achieving multiple technical effects such as precise control of the backward leaning angle, maintaining a stable body position, shortening the operation time, and reducing secondary injuries, providing a more reliable tool for medical emergency and intensive care.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The following is combined with Figure 1-5 The present application is further described in detail. An embodiment of the present application discloses an airway opening device for assisting in resuscitation posture.

[0037] Reference Figure 1 and Figure 2As shown, an auxiliary resuscitation position airway opening device includes a body support plate 100, a flap 300, a driving assembly and a fixing assembly 400; The body support board 100 is designed to support and carry the patient's upper limbs and trunk, ensuring that the patient maintains a stable posture during use, providing a stable and safe support platform, effectively reducing operational errors caused by patient movement, and improving emergency treatment efficiency.

[0038] The flap 300 is hinged to the top of the trunk support plate 100, allowing it to rotate freely around the axis. When the patient's head position needs to be adjusted, the flap 300 can be tilted backward manually or electrically to help the patient's head naturally tilt back and achieve the effect of opening the airway. This design not only simplifies the operation process, but also enables rapid response without affecting other medical procedures, thereby improving the speed and accuracy of emergency treatment. In addition, the angle of the flap 300 can be flexibly adjusted to accommodate patients with different airway opening angle requirements.

[0039] The drive assembly is firmly mounted on the front end of the trunk support plate 100 and is responsible for controlling the movement of the flap 300. It is equipped with a sophisticated motor system that can automatically complete the flipping action according to preset parameters. The high degree of automation reduces the workload of medical staff and makes the whole process smoother. In addition, the feedback mechanism of the motor system can monitor the position of the flap 300 in real time to ensure that each operation can be performed accurately and without error.

[0040] The fixing assembly 400 is arranged on the flap 300, and is mainly used to fix the patient's head to prevent it from unnecessary displacement during the backward tilting process. Good fixing performance greatly enhances the safety of treatment and avoids the risk caused by head shaking.

[0041] An ultrasonic imager is also installed on the body support plate 100. The ultrasonic imager is integrated at the top of the body support plate 100 and can monitor the status of the patient's airway in real time.

[0042] Reference Figure 1 and Figure 2 As shown, the trunk support plate 100 is not only used to support and carry the patient's upper limbs and trunk, but also has a specially designed inclined surface 140 on its top surface, which is located at a position corresponding to the patient's waist. This design is intended to reduce the height difference between the trunk support plate 100 and the patient's contact surface after being placed horizontally, ensuring a smooth transition between the two, thereby reducing the discomfort caused to the patient by sudden height changes. It effectively improves the fit between the patient and the support plate 520, reduces local pressure concentration, and reduces the risk of skin damage. In addition, this design can also help patients maintain a natural spinal curve, improve overall comfort, and facilitate long-term use.

[0043] The curved surface 110 is provided at the connection between the inclined surface 140 and the horizontal top surface of the trunk support plate 100. This design makes the transition from the horizontal surface to the inclined surface 140 softer, avoiding potential harm to the patient by sharp edges. The curved surface 110 adopts an ergonomic curvature to ensure that the patient can feel maximum comfort in any posture. The design of the curved surface 110 not only improves the aesthetics and professionalism of the product, but more importantly, it significantly enhances the user experience. The smooth transition reduces friction and prevents skin abrasion.

[0044] Reference Figure 1 and Figure 2 As shown, the fixing assembly 400 includes two rotating shafts 420 and two clamping plates 410. A rotating cavity 310 for accommodating the two clamping plates 410 is provided on the flap 300 in a direction perpendicular to the top surface. The rotating shaft 420 is installed in the rotating cavity 310, and the axial direction of the two rotating shafts 420 is along the extension direction of the neck of the patient after the head is placed.

[0045] Not in use: When not in use, the two splints 410 can be flipped to a horizontal position, just covering the rotating cavity 310, maintaining the overall flatness of the device, and facilitating the placement of the patient's head when lying flat.

[0046] Usage: When the patient needs to use it, the head is placed at the joint of the two splints 410. At this time, the flap 300 is turned over, and the two splints 410 can be turned over to the middle joint, so as to clamp the two sides of the back of the patient's head and part of the cheeks, thereby effectively fixing the patient's head.

[0047] The surface of the splint 410 is made of soft and elastic medical-grade material, and the surface is anti-slip treated to provide comfortable support, reduce the feeling of pressure, and ensure that no damage is caused to the patient's skin during the clamping process.

[0048] A corresponding slider 430 is disposed at both ends of each rotating shaft 420. Two slide grooves 320 are provided on the flip plate 300, each slide groove 320 corresponds to a rotating shaft 420, and the two slide grooves 320 are disposed opposite to each other. The slider 430 is slidably disposed in the slide groove 320 to ensure that the clamping plate 410 can move smoothly during the flipping process. A spring 440 is also disposed in each slide groove 320, one end of the spring 440 abuts against the side wall of the slide groove 320, and the other end is fixedly connected to the slider 430.

[0049] Unused state: When the clamping plates 410 are not in use, the spring 440 pushes the slider 430 to abut against the side wall of the slide slot 320, so that the two clamping plates 410 remain in a horizontal state and cover the rotating cavity 310. At this time, the clamping plates 410 and the flap 300 form a flat surface for easy storage and transportation.

[0050] Usage: When the patient needs to use it, the flap 300 is turned over, the splint 410 is turned toward the middle joint, and the slider 430 slides in the slide groove 320. Due to the action of the spring 440, the slider 430 automatically adjusts its position according to the size of the patient's head, ensuring that the splint 410 can fit tightly against both sides of the back of the patient's head and part of the cheek, providing a stable clamping force.

[0051] The design of the spring 440 enables the slider 430 to slide freely in the slide groove 320, and the spring 440 can produce an appropriate squeezing effect on the slider 430 in the case of different patient head sizes. This adaptive adjustment function ensures that the splint 410 can flexibly adapt to the head contours of different patients and provide a personalized clamping effect. The elastic effect of the spring 440 can not only ensure that the splint 410 moves smoothly during the flipping process, but also provide continuous pressure when clamping the patient's head, ensuring that the clamping is firm but not too tight, avoiding discomfort or injury to the patient.

[0052] Usage process Preparation: Before use, ensure that the clamping plate 410 is in a horizontal covering state, check whether the slider 430 is located on the side wall of the slide groove 320, and whether the spring 440 works normally.

[0053] Position the head: Gently place the patient's head on the joint of the two splints 410 to ensure the head is in the correct position.

[0054] Flipping and fixing: Flip the flap 300 to flip the two clamps 410 toward the middle joint, and the slider 430 slides in the slide groove 320, so that the clamps 410 clamp the two sides of the back of the patient's head and part of the cheek. At this time, the squeezing effect of the spring 440 ensures that the clamps 410 fit closely to the patient's head, providing a stable clamping force.

[0055] Adjustment and inspection: According to the specific conditions of the patient, the position and clamping strength of the splint 410 are appropriately adjusted to ensure that the patient's head is fully fixed while maintaining smooth breathing.

[0056] Reset: After use, the flap 300 is flipped back to its original position, the spring 440 automatically pushes the slider 430 back to the side wall of the slide groove 320, and the clamping plate 410 returns to the horizontal covering state, which is convenient for next use.

[0057] The fixing assembly 400 further includes a limiting member for limiting the excessive turning of the two clamping plates 410 , and the limiting member is used to limit the turning of the clamping plates 410 in a non-turned state.

[0058] The limiting member is slidably disposed at the top end of the flap 300 away from the body support plate 100 , and a guide component is also installed on the limiting member to assist it in sliding along a direction perpendicular to the top surface of the flap 300 .

[0059] The stopper is a baffle 450 slidably disposed at the top of the flap 300 away from the body support plate 100, and the sliding direction of the baffle 450 is perpendicular to the plane of the flap 300 on which the patient's head is placed. A guide component is installed on the stopper to assist it in sliding in a direction perpendicular to the top surface of the flap 300. The guide component can be a guide rail, a pulley or other similar mechanical structure to ensure that the stopper can slide smoothly.

[0060] The main function of the stopper is to prevent the clamping plate 410 from over-turning during the turning process. When the clamping plate 410 turns to a predetermined angle, the stopper will prevent the clamping plate 410 from turning further, ensuring that the clamping plate 410 always remains within a safe working range.

[0061] In the non-flipped state, the limiter can effectively limit the flipping of the splint 410, ensuring that the splint 410 maintains a horizontal covering state, and avoiding accidental flipping of the splint 410 due to external factors (such as collision or misoperation).

[0062] When assisting the patient to open the airway, the top of the patient's head will abut against the plane of the flap 300 facing the body support plate 100. At this time, the limiter plays a supporting role, preventing the unconscious patient from being stretched due to the gravity of the head during the process of assisting the patient to open the airway, thereby ensuring the safety of the patient.

[0063] Reference Figure 3 and Figure 4 As shown, the guide assembly includes a slide plate 460 and a magnetic block 470. A guide groove 330 for the slide plate 460 to slide is provided on the flap 300. The shape and size of the guide groove 330 ensure that the slide plate 460 will not deviate or get stuck during the sliding process, thereby ensuring smooth sliding. Two positioning grooves are also provided on the flap 300. The two positioning grooves are located on both sides of the guide groove 330 and are opposite to each other to form a symmetrical structure. An iron sheet is provided at the bottom of each positioning groove.

[0064] The slide plate 460 is fixedly connected to the bottom of the baffle 450 to ensure that the baffle 450 can slide smoothly along the predetermined path. A magnetic block 470 is fixedly connected to each side of the slide plate 460, and the two magnetic blocks 470 are respectively slidably set in two positioning grooves on the flap 300. The design of the magnetic block 470 not only provides a sliding guide function, but also can be fixed at a specified position by magnetic attraction. The iron sheet is used in conjunction with the magnetic block 470. When the magnetic block 470 slides to the end of the positioning groove, the magnetic block 470 contacts the iron sheet and forms a magnetic fixation.

[0065] When the baffle 450 needs to slide, the operator can manually push the baffle 450, and the slide plate 460 will slide along the guide groove 330 to ensure that the sliding direction of the baffle 450 is always perpendicular to the top surface of the flap 300. There is a magnetic block 470 on each side of the slide plate 460, and the magnetic block 470 slides along the positioning groove to ensure that the slide plate 460 remains stable during the sliding process.

[0066] When the baffle 450 slides to the designated position, the magnetic blocks 470 on both sides of the slide plate 460 will contact the iron sheet at the bottom of the positioning groove, and the magnetic attraction between the magnetic blocks 470 and the iron sheet will firmly fix the baffle 450 at this position. This magnetic attraction fixing method is not only simple and reliable, but also can adjust the fixing strength by selecting magnetic blocks 470 of different strengths to meet different usage requirements.

[0067] The magnetic fixing design also has a certain buffering effect. Even if it is subjected to a slight external impact, the baffle 450 will not loosen easily, further enhancing the safety and stability of the device.

[0068] Reference Figure 3 and Figure 4 As shown, the bottom surface of the baffle 450 facing the flap 300 is a positioning surface 452, and the positioning surface 452 is the side of the baffle 450 facing the flap 300 that contacts the patient's head. The length direction of the baffle 450 extends from the midline of the flap 300 to the rotation axis 420 of the two splints 410.

[0069] The clamping plate 410 is centered on the rotation axis 420 and divides the side contacting the patient into a placement surface 411 for placing the patient's head and a clamping surface 412 for clamping the patient's cheek.

[0070] When the clamping plate 410 is not in use, the spring 440 pushes the slider 430 to abut against the side wall of the slide groove 320, so that the two clamping plates 410 remain in a horizontal state and cover the rotating chamber 310. At this time, the positioning surface 452 of the baffle 450 is just located in the middle of the two clamping plates 410, pressed on the placement surface 411, and the length direction of the baffle 450 crosses the center line of the rotating shaft 420 of the clamping plate 410, pressed on the clamping surface 412, thereby preventing the clamping plate 410 from turning over. This design ensures that the clamping plate 410 will not turn over accidentally when not in use, maintaining the safety of the device.

[0071] The side walls of the baffle 450 in two width directions are fixed surfaces 451 . The two fixed surfaces 451 are disposed on both sides of the positioning surface 452 , and the two fixed surfaces 451 are disposed perpendicular to the positioning surface 452 .

[0072] When not in use, the positioning surface 452 of the baffle 450 is pressed on the placement surface 411 and the clamping surface 412 of the clamping plate 410 to prevent the clamping plate 410 from turning over. At this time, the clamping plate 410 remains horizontal and covers the rotating chamber 310, and the device is in a safe standby state.

[0073] When the patient needs to use it, the operator can manually pull the baffle 450, and the slide plate 460 slides along the guide groove 330 to pull out the baffle 450. At this time, the positioning surface 452 of the baffle 450 no longer restricts the splint 410, and the splint 410 flips toward the middle joint under the gravity of the patient's head.

[0074] The slider 430 slides in the slide groove 320. Due to the action of the spring 440, the slider 430 automatically adjusts its position according to the size of the patient's head, ensuring that the splint 410 can fit closely to both sides of the back of the patient's head and part of the cheek. This automatic adjustment function not only improves the convenience of use, but also provides personalized support according to the head size of different patients, enhancing comfort and safety.

[0075] When the splint 410 reaches the maximum turning angle, the blocking surface of the splint 410 abuts against the side wall of the clamping surface 412 to limit the splint 410 from turning excessively, thereby preventing the splint 410 from causing discomfort or injury to the patient due to excessive turning.

[0076] Reference Figure 3 and Figure 5 As shown, the bottom of the flap 300 further includes a support plate 520 and a fixed shaft 510 . The bottom surface of the flap 300 is provided with a receiving groove 340 . The fixed shaft 510 is fixedly installed in the receiving groove 340 . The support plate 520 is rotatably installed on the fixed shaft 510 .

[0077] When the flap 300 is in a horizontal position (ie, non-flipped state), the support plate 520 is received in the receiving groove 340 and is flush with the bottom surface of the flap 300. At this time, the support plate 520 does not cause any obstruction to the placement or movement of the flap 300, and the device can be conveniently carried or stored.

[0078] When the flap 300 needs to be flipped over to the ground for use, the operator can manually rotate the support plate 520 out of the receiving groove 340. The support plate 520 gradually unfolds and contacts the ground through the rotation of the fixed shaft 510 to form a stable support point. The unfolding angle of the support plate 520 can be adjusted according to actual needs to ensure stable support of the flap 300 at different heights. The design of the support plate 520 allows the flap 300 to be easily flipped and remain stable after flipping, avoiding safety hazards caused by unstable support.

[0079] Reference Figure 1 and Figure 2As shown, the ultrasonic imager includes a detector 150 mounted on the body support plate 100 and an imager for receiving the detector 150. The detector 150 is mounted on the body support plate 100 and is mainly used to detect the opening state of the patient's airway. Through ultrasonic technology, the detector 150 can penetrate the skin and soft tissue to generate high-resolution airway images. This enables medical staff to observe the patient's airway condition in real time during emergency treatment. The imager is connected to the detector 150 and is responsible for receiving and processing the ultrasonic image data collected by the detector 150 and displaying it on the screen.

[0080] The body support plate 100 is also equipped with a processor 130 and a pressure sensor 120. The processor 130 is electrically connected to the pressure sensor 120 and the imager. The main function of the processor 130 is to receive and process the data transmitted by the pressure sensor 120, and to display the data in real time on the screen of the imager. The pressure sensor 120 is arranged on the top surface of the body support plate 100 and directly contacts the patient's back. Its main function is to detect the pressure data on the patient's back during CPR. Through the calculation and analysis of the processor 130, medical staff can intuitively understand the pressure the patient is subjected to during CPR, ensure that the pressure is moderate, and avoid excessive or insufficient pressure to cause harm to the patient.

[0081] Reference Figure 3 and Figure 5 As shown, the driving mechanism 200 includes a driving motor 210 and a driving shaft 220. The driving motor 210 is fixedly mounted on the body support plate 100, and its output shaft is fixedly connected to the driving shaft 220 coaxially. The driving motor 210 is connected to the processor 130 by electrical connection, receives control instructions from the processor 130, and realizes precise motion control. The driving shaft 220 is rotatably arranged at the front end of the body support plate 100 and can rotate around its axis. One end of the driving shaft 220 is fixedly connected to the output shaft of the driving motor 210, and the other end is connected to the flap 300. Driven by the driving motor 210, the driving shaft 220 can drive the flap 300 to flip.
