Technical Field
[0001] This utility model belongs to the field of medical training equipment technology, specifically relating to a training device for cardiopulmonary resuscitation (CPR). Background Technology
[0002] Cardiopulmonary resuscitation (CPR) is an emergency first aid technique used for patients who have suffered cardiac arrest or respiratory arrest. It involves chest compressions and artificial respiration to maintain blood circulation and oxygen supply, buying time for professional resuscitation. Medical personnel typically require specialized training to perform CPR effectively.
[0003] Current cardiopulmonary resuscitation (CPR) training typically involves trainees practicing on mannequins. Indicators such as compression force, compression frequency, and compression depth all require guidance and correction from professional instructors, resulting in slow training efficiency and significant difficulties in promotion and popularization.
[0004] Therefore, it is necessary to design a training device that facilitates the quantification of compression force, compression frequency, and compression depth during CPR training. Utility Model Content

[0023] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.
[0024] like Figures 1 to 4 As shown, this embodiment designs a training device for cardiopulmonary resuscitation (CPR), including components such as a compression column 2, a compression spring 3, a pressure sensor 6, a compression base 4, and a support base 9.
[0025] The support base 9 is square in shape. When in use, the support base 9 can be placed on a table or on a mannequin.
[0026] The pressing base 4 is fixedly installed on the support base 9 during use. The pressing base 4 includes a guide tube and a disc portion. The disc portion is connected to the lower end of the guide tube, making the pressing base 4 T-shaped. The guide tube is also located in the middle of the pressing base 4. A first mounting position in the shape of a circular groove is provided at the center of the pressing base 4. The disc portion is embedded in the first mounting position and fixed by screws.
[0027] The pressing column 2 is slidably disposed within the guide tube; the pressing column 2 can move vertically up and down along the guide tube. A protruding ridge is provided on the outer wall of the pressing column 2, and a vertical groove is provided on the inner wall of the guide tube; the protruding ridge is slidably disposed within the vertical groove, and the cooperation between the protruding ridge and the vertical groove restricts the rotation of the pressing column 2 relative to the guide tube. The upper end of the pressing column 2 has a disc-shaped pressing head 1, which facilitates pressing with the trainee's palm.
[0028] The compression spring 3 is sleeved outside the guide tube, and the upper and lower ends of the compression spring 3 abut against the pressing head 1 and the pressing base 4 respectively. When the pressing column 2 is pressed down, the compression spring 3 is compressed, and when the pressing column 2 is released, the compression spring 3 pushes the pressing head 1 and the pressing column 2 to move upward, so that they are reset.
[0029] The pressure sensor 6 is located in the lower center of the compression base 4, directly opposite the compression post 2. A square-groove-shaped second mounting position is provided at the center of the first mounting position. The pressure sensor 6 is embedded in the first mounting position and fixed by the fixing screw 7. After the compression post 2 is pressed down a certain distance, it contacts the pressure sensor 6, causing the pressure sensor 6 to generate a pressure signal. The distance the compression head 1 moves down along the guide tube is used to simulate the compression depth of cardiopulmonary resuscitation (CPR). That is, the pressure sensor 6 generates a pressure signal each time the compression depth is reached, making it convenient for trainees to judge whether their compression depth is sufficient during training. Furthermore, the strength of the pressure signal generated after the compression post 2 contacts the pressure sensor 6 can be used to determine the compression force, so that the pressure detected by the pressure sensor 6 can be used to simulate the compression force of CPR.
[0030] A force transmission plate 5 is placed above the pressure sensor 6. The force transmission plate 5 abuts against the trigger end of the pressure sensor 6. After the pressing column 2 is pressed, the lower end of the pressing column 2 contacts the force transmission plate 5, so as to transmit pressure to the pressure sensor 6 through the force transmission plate 5, thereby protecting the pressure sensor 6 and improving the detection accuracy of the pressure sensor 6.
[0031] A PCB circuit board 8 is also mounted on the support base 9. The PCB circuit board 8 is connected to the pressure sensor 6 to receive signals from the pressure sensor 6. An analog-to-digital converter circuit can be installed on the PCB circuit board 8 to convert the pressure signal output by the pressure sensor 6 into a digital signal. The PCB circuit board 8 can also be equipped with an MCU microcontroller (i.e., a storage module) for recording and storing digital signals. Furthermore, the PCB circuit board 8 includes wireless communication modules such as Wi-Fi and Bluetooth for transmitting digital signals. A display or other device can be used to communicate with the PCB circuit board 8 to display parameters such as compression frequency and compression force during CPR training. This also allows trainees to determine whether the compression depth is sufficient based on the presence or absence of compression force data.
[0032] A central hole is provided at the center of the PCB circuit board 8, through which the guide tube and compression spring 3 pass, thereby facilitating the integration of the training device in this embodiment.
[0033] Current CPR training is generally conducted by the trainee in... Figure 4 Training on the mannequin shown presents challenges in determining parameters such as pressure intensity, frequency, and depth, requiring guidance and correction from professional instructors. However, in... Figures 1 to 3When training with the CPR training equipment shown, the pressure sensor 6 will only be triggered and display the pressure signal when the trainee reaches the required compression depth. The pressure signal can be connected to the circuit to convert the pressure signal into a digital signal, which will then be displayed on the monitor. The trainee can more accurately judge the compression force and compression frequency based on the displayed pressure value and the frequency of the pressure value, and make real-time adjustments to improve the effectiveness and effect of CPR training.
[0034] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
