Description

Technical Field

[0001] This utility model relates to the field of medical training equipment technology, and more specifically, to a pressure training device. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) training equipment is an important tool for improving rescuers' emergency skills. Existing equipment mainly focuses on the detection and feedback of action parameters such as compression depth, frequency, and rebound, and can provide basic assessment of operation techniques.

[0003] However, these devices lack the ability to monitor the rescuer's physiological state, failing to acquire key physiological data such as heart rate, respiratory rate, and muscle fatigue levels. Consequently, it is difficult to comprehensively and objectively assess training effectiveness and the rescuer's actual physical endurance. Because they cannot monitor the rescuer's physiological changes in real time during training, existing systems struggle to determine whether the current training intensity is appropriate, potentially leading to insufficient training that hinders skill acquisition or overtraining that causes injury. This raises concerns about the scientific validity and safety of the training. While some high-end training systems attempt to compensate for this deficiency by using external heart rate monitors, finger-clip pulse oximeters, or wearable sensors, these solutions require additional specialized patches or wearable devices, increasing system complexity and procurement costs while reducing ease of use and user experience.

[0025] Cardiopulmonary resuscitation (CPR) training equipment is an important tool for improving rescuers' emergency skills. Existing equipment mainly focuses on the detection and feedback of action parameters such as compression depth, frequency, and rebound, and can provide basic assessment of operation techniques.

[0026] However, these devices lack the ability to monitor the rescuer's physiological state, failing to acquire key physiological data such as heart rate, respiratory rate, and muscle fatigue levels. Consequently, it is difficult to comprehensively and objectively assess training effectiveness and the rescuer's actual physical endurance. Because they cannot monitor the rescuer's physiological changes in real time during training, existing systems struggle to determine whether the current training intensity is appropriate, potentially leading to insufficient training that hinders skill acquisition or overtraining that causes injury. This raises concerns about the scientific validity and safety of the training. While some high-end training systems attempt to compensate for this deficiency by using external heart rate monitors, finger-clip pulse oximeters, or wearable sensors, these solutions require additional specialized patches or wearable devices, increasing system complexity and procurement costs while reducing ease of use and user experience.

[0027] Therefore, there is an urgent need to provide a compression training device that integrates physiological state monitoring functions, enabling real-time collection and analysis of the rescuer's physiological parameters without the need for additional clothing. This would improve the comprehensiveness and scientific nature of training assessments, optimize training intensity management, avoid excessive fatigue, and promote the development of CPR training towards intelligence and personalization.

[0028] Please see Figure 1 and Figure 2 This utility model provides a pressing training device 10, including a base 100, a pressing component 200, a data acquisition module 300, and a processing module 400.

[0029] The pressing component 200 includes a telescopic part 210 and a pressing part 220. The telescopic part 210 is cylindrical and one end is connected to the base 100, and the other end is connected to the pressing part 220. The pressing part 220 is provided with a through hole 221. The acquisition module 300 is disposed on the side of the pressing part 220 near the base 100, and the acquisition module 300 is located at the through hole 221. The acquisition module 300 is used to acquire the operator's physiological parameter signals. The processing module 400 is disposed on the base 100 and is electrically connected to the acquisition module 300. It is used to receive and transmit physiological parameter signals to the outside.

[0030] Specifically, the acquisition module 300 is located on the side of the pressing part 220 near the base 100, and at the through hole 221, meaning it is situated in the lower part of the internal space of the pressing part 200, directly facing the axial direction of the through hole 221. This design allows the center of the user's palm to be in close contact with the surface of the pressing part 220 and cover the area of ​​the through hole 221 during pressing training. The infrared light source of the acquisition module 300 can then shine through the through hole 221 onto the skin tissue. The reflected light, modulated by blood pulsation, is captured by the receiver 320, thereby enabling continuous detection of physiological parameters such as heart rate. Because the acquisition module 300 is integrated inside the pressing part 200 rather than being an external device, the inconvenience and increased cost associated with wearing additional sensors are avoided.

[0031] The processing module 400 is housed within the base 100 and is electrically connected to the acquisition module 300 via wires or flexible circuits. It receives physiological parameter signals from the acquisition module 300, amplifies, filters, performs analog-to-digital conversion, and conducts preliminary processing on the signals, ultimately transmitting the digitized physiological parameter signals externally. Based on this design, the processing module 400 not only performs signal processing tasks but also integrates wireless communication functionality, facilitating data interaction with external terminal devices and enhancing the system's intelligence level.

[0032] Therefore, the pressing training device 10 provided in this embodiment of the present invention, by setting a through hole 221 in the pressing part 220 and integrating a data acquisition module 300 below it, realizes the synchronous execution of pressing action and physiological signal acquisition on the same physical interface. It can monitor key physiological indicators such as the operator's heart rate and fatigue level without the need for additional wearable devices, effectively solving the technical problems of low integration, difficult maintenance and data fragmentation caused by the splicing of multiple devices in traditional training systems, and significantly improving the reliability of the system and user experience.

[0033] This device can be understood as highly integrating the mechanical compression feedback mechanism and the physiological signal sensing unit into the same module, forming a functionally integrated training unit. This not only simplifies the overall structure and reduces production and maintenance costs, but also provides a time-synchronized dual-dimensional data foundation of compression quality and physiological response for subsequent data analysis. This is conducive to establishing a correlation model between compression intensity and the rescuer's physical exertion, thereby scientifically assessing whether the training load is appropriate.

[0034] For example, in first aid training scenarios, multiple trainees sequentially use the same device to perform standardized CPR training. The system can automatically record each trainee's compression frequency, depth, and corresponding heart rate change curves. Instructors can analyze the backend data to determine whether individuals are overly fatigued or have unstable techniques, thereby developing personalized training plans. This structure is particularly suitable for medical schools, emergency rescue organizations, and other settings requiring large-scale, high-frequency CPR skills training, and has promising prospects for widespread application.

[0035] Based on the above design, the pressure training device 10, while ensuring the basic functions of pressure training, expands the physiological state monitoring capabilities and realizes the fusion acquisition of "action-physiology" dual-modal data. It has outstanding advantages such as compact structure, convenient use, and strong data integrity, meeting the needs of modern intelligent medical training equipment for high integration and multifunctionality.

[0036] It is worth mentioning that the pressing part 200 is made of medical-grade silicone material in one piece, which has good elasticity and biocompatibility, and provides a stable pressing feedback feel. Its thickness is 15-25mm and it can withstand a pressing force of 150-200N.

[0037] Furthermore, the pressing member 200 also includes a light-transmitting film 230, which is disposed on the pressing part 220 and covers the through hole 221.

[0038] In this embodiment, when the operator performs CPR training, the palm directly contacts the surface of the pressing part 220. Sweat, dust and other environmental pollutants may enter the device through the through hole 221 and then adhere to the surface of the optical element of the acquisition module 300, causing signal attenuation or detection distortion.

[0039] Specifically, the light-transmitting film 230 acts as a physical barrier, effectively isolating the direct contact path between external pollution sources and internal sensors, preventing sweat penetration or particulate matter deposition from damaging the acquisition module 300, thereby ensuring the stability of optical signal transmission and detection accuracy.

[0040] In this design, the light-transmitting membrane 230 not only serves a protective and sealing function, but also, due to its excellent infrared transmittance, allows the infrared light signal emitted by the acquisition module 300 to pass smoothly through the membrane layer and irradiate the skin tissue. Furthermore, the reflected light signal can be reversed and returned to the receiver 320, ensuring unimpeded continuous acquisition of physiological parameter signals. Based on the above description, the light-transmitting membrane 230 maintains the integrity of the optical path while achieving sealing and protection, thus balancing the reliability of the device and the normal operation of the detection function.

[0041] Optionally, the light-transmitting film 230 can be a 0.2mm thick polyurethane film with an infrared transmittance of >85% and a tensile strength of >30MPa, and is fixed above the through hole 221 with medical adhesive to ensure sealing and infrared optical performance.

[0042] Furthermore, the acquisition module 300 includes a transmitter 310 and a receiver 320. The transmitter 310 is used to emit light signals toward the through hole 221, and the receiver 320 is used to receive the reflected light signals and transmit the physiological parameter signals corresponding to the reflected light signals to the processing module 400.

[0043] In this embodiment, the transmitter 310 is disposed on the side of the pressing part 220 near the base 100 and at the corresponding position of the through hole 221, for emitting infrared light signals of a specific wavelength toward the through hole 221. The light signals penetrate the surface of the pressing part 220 through the through hole 221 and irradiate the skin tissue of the palm area of ​​the operator's hand.

[0044] Specifically, when the operator performs CPR compressions, the palm covers the area of ​​the through hole 221. The light signal emitted by the transmitter 310 passes through the light-transmitting membrane 230 and enters the subcutaneous microvascular layer. As the blood volume changes periodically with the heartbeat, the absorption and scattering of the light signal in the tissue are modulated. Some of the reflected light returns along the original path and is captured by the receiver 320 through the through hole 221.

[0045] In this design, the receiver 320 and transmitter 310 work together to form a reflective optical detection loop. The receiver 320 converts the received, time-varying intensity of reflected light into a corresponding electrical signal. This electrical signal carries information related to heart rate and pulse waveforms, i.e., physiological parameter signals. This signal is then transmitted to the processing module 400 via wires or flexible circuits for subsequent amplification, filtering, and digitization processing, ultimately enabling real-time monitoring of the operator's heart rate and other physiological states.

[0046] Optionally, the transmitter 310 may be an infrared LED transmitter 310, and the receiver 320 may be an infrared photosensitive receiver 320.

[0047] Furthermore, the acquisition module 300 also includes a focusing lens 330, which is located at the through hole 221.

[0048] When reflected light returns from the subcutaneous tissue, the focusing lens 330 simultaneously acts as a light-gathering lens, converging the originally scattered returned light signal and guiding it to the photosensitive surface of the receiver 320, significantly enhancing the receiver 320's ability to capture weak physiological signals. Based on the above description, this structure effectively improves the signal coupling efficiency in the optical path, reduces the risk of data fluctuations or misjudgments caused by light loss, and maintains a stable response, especially under complex conditions such as low perfusion or motion interference.

[0049] In addition, the acquisition module 300 also includes a shielding cover 340, which is disposed between the transmitter 310, the receiver 320 and the pressing part 220.

[0050] In this embodiment, when an operator performs CPR training under natural light or indoor lighting, visible light and near-infrared background light from the environment may enter the pressing element 200 through the through-hole 221 and reach the photosensitive surface of the receiver 320, causing non-physiologically relevant components to be mixed into the received light signal, thereby affecting the accuracy of extracting physiological parameters such as heart rate. Therefore, a shielding cover 340 is placed between the transmitter 310, the receiver 320, and the pressing element 220 to form a physical barrier, blocking ambient light from the side or at an angle from directly illuminating the optical sensitive element, thereby effectively suppressing the interference of external light pollution on the detection process.

[0051] Furthermore, the through hole 221 is located at the center of the pressing part 220, and it is a circular through hole 221 with a diameter of 3-5mm.

[0052] Specifically, the through-hole 221 is located at the center of the pressing part 220, so that the acquisition module 300 below the hole can directly face the densely vascularized area of ​​the palm, namely the intersection of the radial and ulnar arteries. This area has thin subcutaneous tissue and prominent blood flow signals, making it suitable as a detection window for optical physiological signals. This design ensures that the infrared light signal can penetrate the skin to the maximum extent and be modulated by pulsating blood flow, thereby improving the sensitivity and accuracy of heart rate detection.

[0053] The central part of the pressing part 220 is concave, which can better accommodate the contour of the palm, allowing for a larger area of ​​contact between the palm and the pressing surface, reducing local stress concentration, and improving stability and comfort during the pressing process. This not only helps the operator maintain a standard pressing posture, but also reduces the risk of pressing position deviation caused by palm slippage or offset.

[0054] Furthermore, the pressing training device 10 also includes a battery module 500, which is detachably mounted on the base 100 and connected to the processing module 400.

[0055] The battery module 500 is directly connected to the processing module 400 to provide it with a stable operating voltage, ensuring that the acquisition, processing and transmission of physiological parameter signals can be carried out normally.

[0056] Optionally, the battery module 500 can be powered by AAA batteries.

[0057] Furthermore, the processing module 400 is equipped with a wireless communication device, which is used to wirelessly transmit the received physiological parameter signals to the outside.

[0058] In this embodiment, the processing module 400 not only undertakes the task of amplifying, filtering and digitizing the physiological parameter signals received from the self-acquisition module 300, but also completes the remote data transmission function through the built-in wireless communication device.

[0059] Specifically, when an operator performs CPR compression training, the raw photoelectric signals acquired by the acquisition module 300 are analyzed by the processing module 400 into physiological parameters such as heart rate and heart rate variability. The wireless communication device then packages this data and wirelessly transmits it to a mobile terminal or host computer system, such as a tablet, smartphone, or training management host. This design allows for real-time sharing and centralized monitoring of physiological state information during training without relying on a physical connection.

[0060] Alternatively, the wireless communication device may be a Bluetooth communication module.

[0061] Furthermore, the pressing training device 10 also includes an elastic element 600, one end of which is connected to the base 100, and the other end is disposed inside the pressing member 200 and connected to the top wall of the pressing member 200.

[0062] In this embodiment, when the operator applies downward pressure to the pressing part 220, the pressing member 200 moves downward along the guide direction of the telescopic part 210. This movement causes the elastic member 600 to be compressed, thereby generating a gradually increasing reverse elastic force.

[0063] Specifically, one end of the elastic element 600 is fixed to the base 100, and the other end is connected to the top wall inside the pressing element 200, that is, the inner surface of the side closest to the user's palm, so that its axis is aligned with the pressing movement direction, ensuring a direct and stable force transmission path. With this design, during the pressing process, the elastic element 600 continuously provides a displacement-related restoring force, allowing the operator to obtain a progressive tactile feedback close to the depression of the human sternum.

[0064] Optionally, the elastic element 600 can be a stainless steel compression spring with a spring constant of 200 N / m and a compression stroke of 15-20 mm.

[0065] In summary, this utility model provides a pressure training device 10. By setting the acquisition module 300 on the side of the pressing part 220 near the base 100 and located at the through hole 221, it means that it is located at the lower part of the internal space of the pressing part 200 and directly facing the axial direction of the through hole 221. When the operator performs pressure training, the center of the palm is in close contact with the surface of the pressing part 220 and covers the area of ​​the through hole 221. The infrared light source of the acquisition module 300 can shine through the through hole 221 to the skin tissue. The reflected light after being modulated by blood pulsation is captured by the receiver 320, thereby realizing the continuous detection of physiological parameters such as heart rate. Since the acquisition module 300 is integrated inside the pressing component 200 rather than being an external device, the inconvenience and increased cost associated with wearing additional sensors are avoided. The processing module 400 is located inside the base 100 and is electrically connected to the acquisition module 300 via wires or flexible circuits. It receives physiological parameter signals from the acquisition module 300, amplifies, filters, performs analog-to-digital conversion and preliminary processing on these signals, and finally transmits the digitized physiological parameter signals externally. Based on the above design, the processing module 400 not only undertakes signal processing tasks but also integrates wireless communication functions, facilitating data interaction with external terminal devices and enhancing the intelligence level of the compression training device 10.

[0066] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
