Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a cardiopulmonary resuscitation device and its method of use. Background Technology

[0002] Early cardiopulmonary resuscitation (CPR) is crucial for saving patients experiencing respiratory and cardiac arrest. Currently, most automated cardiopulmonary resuscitation (CPR) devices use a strap to perform chest compressions, and these straps are typically connected via simple adhesive tape or clips. When a patient requires CPR, the strap is secured to the patient's chest using tape or clips, and a power mechanism then contracts the strap to perform chest compressions.

[0003] Current automated cardiopulmonary resuscitation (CPR) devices use simple adhesive or clips, which cannot provide a quick and reliable connection. The connection process is cumbersome, wastes rescue time, or is prone to loosening, leading to unstable CPR.

[0004] In addition, smaller straps or connecting devices can easily generate excessive pressure in a localized area, causing secondary injury to the patient, affecting the rescue effect and reducing the success rate of rescue. Summary of the Invention

[0005] The primary objective of this invention is to provide a cardiopulmonary resuscitation device that enables rapid and stable connection of a chest compression strap while avoiding secondary injury to the patient during chest compressions.

[0006] The second objective of this invention is to provide a method of using the above-mentioned cardiopulmonary resuscitation device, which can effectively improve the effect of cardiopulmonary resuscitation and increase the success rate of rescue.

[0007] The cardiopulmonary resuscitation device provided by the present invention includes: a pressing component, a driving component, a connecting component, and a control module. The connecting component is connected to the driving component and the pressing component respectively, and is used to cover and fix the pressing component on the patient's chest and apply pressing force to the pressing component under the action of the driving component.

[0008] The pressing component is equipped with a pressure sensor. Both the pressure sensor and the driving component are electrically connected to the control module. The control module can control the operation of the driving component through the pressing pressure monitored by the pressure sensor in real time.

[0009] Furthermore, the connecting component includes a connecting strap that is connected separately. The connecting strap includes a first connecting strap located on the outer side and a second connecting strap located on the inner side. The second connecting strap is fixedly connected to the pressing component.

[0010] Furthermore, engaging portions are provided at intervals on the inner side of the first connecting strip and on the side of the second connecting strip facing away from the pressing component. The engaging portions include a locking strip and a flat groove extending along the width direction of the connecting strip. Permanent magnets are provided on the locking strip of the first connecting strip and the locking strip of the second connecting strip.

[0011] Furthermore, the first connecting strip has a groove on its locking strip, and the second connecting strip has a protrusion on its flat groove that can engage with the groove. The groove and the protrusion are arranged on the axial center line of the connecting strip.

[0012] Furthermore, the first connecting strip is also provided with an armature, and the second connecting strip is provided with an electromagnet positioned opposite to the armature. A position sensor for detecting the position of the armature is installed on the electromagnet, and the position sensor is electrically connected to the control module.

[0013] Furthermore, the drive assembly includes two motors that rotate in opposite directions. Both the first connecting belt and the second connecting belt are connected to straps that can extend outward on both sides of the pressing assembly. The extended ends of the straps are respectively connected to the output shafts of the motors.

[0014] Furthermore, the pressing component includes a cushioning air cushion, the interior of which is evenly distributed with multiple air columns, and the sidewalls of the air columns are provided with pressure relief holes for adjusting the pressing pressure.

[0015] Furthermore, the air column comprises multiple rows spaced apart along the length of the buffer air cushion, each air column including one pressure relief hole, the diameter of the pressure relief hole on each row of air columns being the same, and the diameter of the pressure relief hole on each row of air columns being different.

[0016] Furthermore, the pressure sensor comprises multiple sensors, which are evenly distributed along the axial centerline of the cushioning air pad.

[0017] A method of using the above-mentioned cardiopulmonary resuscitation device includes the following steps:

[0018] 1) The compression assembly is wrapped and fixed to the patient's chest via the connecting component;

[0019] 2) The control module controls the operation of the drive components based on signals detected by the position sensor and pressure sensor;

[0020] 3) Continue pressing the patient with the compression device until the compression is finished.

[0021] The main advantages of this invention are: by connecting the connecting component to the driving component and the pressing component respectively, the pressing component can be quickly wrapped and fixed on the patient's chest, and the connecting component is connected to the driving component, so that the pressing component applies pressing force under the drive of the connecting component and the driving component, which effectively improves the rescue efficiency.

[0022] By using pressure sensors on the pressing assembly and controlling the operation of the drive assembly through the control module, a reliable closed-loop control system is formed, which can effectively avoid excessive pressure on the patient and effectively reduce secondary harm to the patient.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please refer to Figure 1 The present invention provides a cardiopulmonary resuscitation device, comprising: a pressing component, a driving component, a connecting component, and a control module. The connecting component is connected to the driving component and the pressing component respectively, and is used to cover and fix the pressing component on the patient's chest and apply pressing force to the pressing component under the action of the driving component.

[0040] The pressing component is equipped with a pressure sensor 16. The pressure sensor 16 and the driving component are both electrically connected to the control module. The control module can control the operation of the driving component through the pressing pressure monitored in real time by the pressure sensor 16.

[0041] The cardiopulmonary resuscitation device of this invention is mainly used for performing cardiopulmonary resuscitation compressions on patients and monitoring the compression force applied to the patient's chest in real time. The compression component is covered and fixed to the patient's chest by a connecting component, and the connecting component is connected to the drive component, which effectively realizes the rapid connection of the connecting component, improves the rescue efficiency, and ensures the stability of the compression component during operation.

[0042] The pressure sensor 16 installed on the compression assembly can detect the compression force applied to the patient and transmit the pressure signal to the control module. The control module can control the operation of the drive assembly through the received pressure signal. When the detected compression force is too large, it can trigger an alarm and stop the cardiopulmonary resuscitation compression by sending a stop signal to the drive assembly, effectively reducing secondary injury to the patient.

[0043] See Figures 2-3 and combined Figure 1 In one embodiment, the connecting assembly enables rapid fixation of the compression component. Specifically, the connecting assembly includes two separate connecting straps, wherein the two connecting straps include a first connecting strap 1 located on the outer side and a second connecting strap 2 located on the inner side, and the second connecting strap 2 is fixedly connected to the compression component. From the perspective of its position on the patient's chest, the first connecting strap 1 can also be defined as the upper connecting strap, and the second connecting strap 2 as the lower connecting strap. Through the engagement of the upper and lower connecting straps and their respective connections to the drive assembly, the compression component can be tightly wrapped and fixed to the patient's chest. After connection and installation, both connecting straps are in a taut state. Through the operation of the drive assembly and the tension force transmitted by the connecting straps, it is converted into pressure applied to the patient by the compression component.

[0044] During connection, the compression assembly can be secured to the patient's chest simply by the quick engagement of the first connecting strap 1 and the second connecting strap 2. To further improve rescue efficiency, the two connecting straps in this embodiment can be connected to the drive assembly separately. When securing the compression assembly, the interlocking between the first connecting strap 1 and the second connecting strap 2 completes the connection and installation of the overall cardiopulmonary resuscitation device, further improving rescue efficiency.

[0045] The quick engagement between the first connecting band 1 and the second connecting band 2 is achieved through their interlocking parts.

[0046] Engaging parts are provided at intervals on the inner side of the first connecting strip 1 and the side of the second connecting strip 2 facing away from the pressing component, enabling the two connecting strips to be quickly connected. The engaging parts specifically include a retaining strip 3 and a flat groove 4 extending along the width direction of the connecting strips. The retaining strip 3 and the flat groove 4 are preferably an integral structure and preferably made of metal. During engagement, the retaining strip 3 on the first connecting strip 1 adheres to the flat groove 4 on the second connecting strip 2, and the retaining strip 3 on the second connecting strip 2 adheres to the flat groove 4 on the first connecting strip 1, causing the two connecting strips to form a "handshake" engagement, ensuring interlocking in the direction of tension.

[0047] To further ensure the stability of the interlocking of the two connecting strips, permanent magnets 5 are provided on the clips 3 of the first connecting strip 1 and the clips 3 of the second connecting strip 2. The permanent magnets 5 can make the clips 3 stick to the corresponding flat grooves 4, thereby improving the stability of the connection.

[0048] To ensure stable interlocking and prevent misalignment of the two connecting strips perpendicular to the tension direction, anti-misalignment components are respectively provided on the first connecting strip 1 and the second connecting strip 2. Specifically, the anti-misalignment component consists of a mutually cooperating groove 6 and a protrusion 7. The groove 6 is located on the retaining strip 3 of the first connecting strip 1, and the protrusion 7 is located on the flat groove 4 of the second connecting strip 2. When the connecting strips are connected, the mutual interlocking of the protrusion 7 and the groove 6 effectively prevents misalignment between the two connecting strips. Combined with the interlocking parts on the two connecting strips, connection stability can be guaranteed in two dimensions, allowing the connecting strips to reliably apply the tension force output by the drive component to the pressing component.

[0049] In this embodiment, the grooves 6 and protrusions 7 are respectively arranged on the axial center line of the connecting belt, which can prevent misalignment from the center position of the connecting belt, ensuring the connection reliability to the greatest extent and fundamentally avoiding the phenomenon of loosening. The grooves 6 and protrusions 7 can also be arranged in two rows extending along the length of the connecting belt, with the two rows of grooves 6 and protrusions 7 symmetrically arranged about the axial center line of the connecting belt. Their arrangement can also be adjusted according to the specific actual situation. For example, the installation positions of the grooves 6 and protrusions 7 can be interchanged on the two connecting belts, which can also achieve the technical effect of preventing misalignment of the two connecting belts in this invention. This will not be elaborated here.

[0050] In another embodiment, in order to make the connection between the two connecting strips more reliable and stable, an armature 8 is provided on the first connecting strip 1, and an electromagnet 9 is provided on the second connecting strip 2, which is positioned opposite to the armature 8. A position sensor 10 for detecting the armature 8 is installed on the electromagnet 9, and the position sensor 10 is electrically connected to the control module.

[0051] The armature 8 and electromagnet 9 ensure a firm and tight fit between the two connecting strips, further guaranteeing connection reliability. The position sensor 10 installed on the electromagnet 9 detects the position of the armature 8, ensuring effective engagement between the electromagnet and the armature 8.

[0052] After the two connecting strips engage, the position sensor 10 detects the connection status of the connecting strips. The position sensor 10 transmits the detected position signal to the control module in real time. The control module determines whether to run the drive component to press based on the received position signal.

[0053] The drive assembly in this embodiment includes two motors (not shown in the figure) that rotate in opposite directions. A strap 11 is connected to both the first connecting belt 1 and the second connecting belt 2. The strap 11 is connected to one side of the first connecting belt 1 and the second connecting belt 2 respectively, and can be configured to extend outward on both sides of the pressing assembly. The extended ends of the strap 11 are respectively connected to the output shafts of the two motors.

[0054] During the pressing process, each motor can rotate in both directions, with the frequency of rotation simulating the frequency of manual pressing, thus replicating the manual pressing action to the greatest extent. The two motors are always in opposite rotational states during operation, enabling them to tighten and release the two straps 11.

[0055] See Figures 4-5 In one preferred embodiment, the pressing component includes a cushioning air cushion 12, which mainly serves to evenly distribute the pressing force. It includes an outer surface layer 13 with an overall closed structure, and multiple air columns 14 are provided inside the surface layer. By providing pressure relief holes 15 on the side walls of the air columns 14, the pressing force can be adjusted to further improve the pressing effect.

[0056] In this embodiment, the cushioning air cushion 12 has minimal deformation during operation. The top and bottom ends of the air column 14 are respectively connected to the top and bottom surfaces of the outer surface layer 13. When the cushioning air cushion 12 is pressed, some air in the air column 14 is discharged from the pressure relief hole 15 to adjust the pressing pressure. When the pressure on the cushioning air cushion 12 is released, the air column 14 will return to its original state under the action of the rebound force of the outer surface layer 13, and at the same time, air will be drawn back through the pressure relief hole 15, thereby achieving the overall cushioning effect.

[0057] The air columns 14, located within the outer surface layer 13, comprise multiple rows. These rows of air columns 14 are evenly spaced along the length of the cushioning air cushion 12, and each air column 14 has a pressure relief hole 15. The arrangement of the air columns 14 is coordinated with the way the cushioning air cushion 12 is wrapped and secured to the patient's chest. When in use, the cushioning air cushion 12 spans the patient's chest along its length. The evenly spaced rows of air columns 14 along its length better adapt to human function, achieving effective pressure on the patient.

[0058] To adjust the pressure levels, the pressure relief holes 15 on each row of air columns 14 have the same diameter, but the diameters of the pressure relief holes 15 on each row of air columns 14 are different. This configuration allows for different pressure levels to be output based on the pressure points of the cushioning air cushion 12, achieving a balanced distribution of pressure and improving the effectiveness of rescue operations.

[0059] It should be noted that, in order to better adapt to the rib structure, the area near the middle is made of cartilage, which has good elasticity and is not easy to break. The pressure relief hole 15 on the middle air column 14 has a small diameter. When pressing, the gas in the air column 14 passes through the pressure relief hole 15 at a slower speed, which can provide a greater downward pressing force. While providing a good pressing effect, it is less likely to damage the patient's ribs.

[0060] In this embodiment, the cushioning air cushion 12 is also equipped with multiple pressure sensors 16. By setting a threshold for the maximum pressing force, when the control module detects that the pressing force is greater than the threshold, it triggers an alarm and controls the motor to stop running, thereby reliably ensuring safety during the pressing process and reducing the risk of secondary injury.

[0061] Multiple pressure sensors 16 are evenly distributed along the axial center line of the cushioning air cushion 12 and across the patient's anterior chest. If any pressure sensor 16 detects an abnormal pressure at any location, it triggers an interlock to stop the pressure, thus ensuring safety to the greatest extent.

[0062] The cardiopulmonary resuscitation device of this invention enables rapid connection and coordination of the connecting straps, forming a stable connection state. By combining it with the anti-misalignment component, it can ensure rapid positioning during connection and prevent longitudinal slippage. At the same time, the position sensor 10 and pressure sensor 16 can form an effective closed-loop control circuit, which can effectively improve the safety of chest compression operation. Overall, it can achieve the technical effects of saving connection time of the external cardiopulmonary resuscitation device and avoiding secondary injury to the patient caused by chest compression.

[0063] The present invention also provides a method of using the above-mentioned cardiopulmonary resuscitation device, specifically including the following steps:

[0064] 1) The cushioning air cushion 12 is wrapped and fixed to the patient's chest by the quick connection of the first connecting strap 1 and the second connecting strap 2;

[0065] 2) Energize the electromagnet 9 so that the electromagnet 9 and the armature 8 are tightly fixed together, and detect the fixed status of the armature 8 and the connecting strip through the position sensor 10.

[0066] 3) Turn on the motor, and use the connecting belt to convert the tension force into compression force to perform CPR chest compressions;

[0067] 4) The control module controls the operation of the drive components based on the signals detected by the position sensor 10 and the pressure sensor 16;

[0068] 5) Continue pressing on the patient using the cushioning air cushion 12 until the pressing is finished.

[0069] See Figure 6 The connection and compression process of the central lung resuscitation device of the present invention specifically includes:

[0070] Place the second connecting strap 2 together with the cushioning air cushion 12 on the patient's chest, with the cushioning air cushion 12 pressed tightly against the patient's chest. Then pick up the first connecting strap 1 from the other side and engage the two connecting straps through the interlocking part. With the cooperation of the permanent magnet 5 and the anti-dislocation component, the two straps are quickly positioned and tightened to form a stable "handshake" structure. At the same time, the corresponding groove 6 and protrusion 7 complete the engagement and positioning to prevent misalignment and slippage.

[0071] When electromagnet 9 is energized, it firmly attracts armature 8, at which point position sensor 10 begins monitoring the fixation status of strap 11. After the connection is stable, drive motor pulls strap 11 to tighten it, and the tension force is converted into chest compression force, which is transmitted to the patient's chest through cushioning air cushion 12 to complete chest compressions.

[0072] The air column 14 in the cushioning air cushion 12 can apply the compression pressure reasonably to the patient's chest. At the same time, the pressure sensor 16 can monitor the pressure inside the cushioning air cushion 12 in real time and feed it back to the external control module to form a closed-loop control system, avoiding secondary injuries caused by compression. After compression, the electromagnet 9 is de-energized, and the restraint 11 is quickly released to allow for further treatment of the patient.

[0073] During the pressing process, the position sensor 10 and the pressure sensor 16 can monitor in real time whether the connecting strip is connected in place and whether the pressing force exceeds the threshold. If an abnormality occurs, the control module will trigger an alarm and stop pressing.

[0074] The method of using the central lung resuscitation device of the present invention can ensure reliable chest compressions to the patient to the greatest extent possible and avoid secondary injury to the patient caused by excessive chest compressions.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
