Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a chest compression auxiliary device. Background Art

[0002] According to statistics, at least 135 million people die from cardiovascular diseases each year worldwide, and 1.8 million people die from cardiac arrest each year in my country, accounting for 6% of the total mortality rate. If patients with cardiac arrest can receive effective rescue within 6 minutes, irreversible damage to brain cells can be avoided, and the success rate of rescue within 1 minute is as high as 90%. Despite this, due to the relatively low mastery rate of cardiopulmonary resuscitation (CPR) in my country, when an emergency occurs, rescuers who have not received professional training find it difficult to meet the requirements of effective frequency and depth of CPR, which leads to the success rate of rescue of cardiac arrest outside hospitals in my country being far less than 1%. Therefore, if professional auxiliary equipment is used to improve the quality of cardiopulmonary resuscitation by non-professional rescuers, the success rate of rescue of patients outside hospitals can be greatly improved.

DETAILED DESCRIPTION

[0034] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the following embodiments are merely illustrative in nature, and the present invention is not intended to limit its applicable objects or uses, and the present invention is not limited to the following embodiments.

[0035] Example

[0036] like Figure 1 As shown, a chest compression assisting device comprises a chest compression assisting pad A, a limiting assisting support structure B and an adaptive base support structure C. The chest compression assisting pad A is detachably connected to a set of limiting assisting support structures B on both sides. The limiting assisting support structure B is provided with an auxiliary plate that can move up and down. The chest compression assisting pad A is connected to the auxiliary plate on both sides. The limiting assisting support structure B is provided with a limiting component for limiting the upward and downward movement range of the auxiliary plate and a detection component for detecting the upward and downward movement frequency of the auxiliary plate. The limiting assisting support structure B is detachably mounted on the adaptive base support structure C. The adaptive base support structure C is used to adjust the installation height of the limiting assisting support structure B. The device also comprises an interactive component for intelligent interaction, and the detection component is connected to the interactive component.

[0037] like Figure 2As shown, a compression indication pattern 1 for indicating the compression position is provided on the chest compression auxiliary pad A, and the interactive component includes a processor, a sounder for emitting a compression prompt sound, and a visual prompter for feedback of the compression frequency detected by the detection component. The sounder, the visual prompter and the detection component are all connected to the processor. In this embodiment, the power supply and the processor are integrated on the chest compression auxiliary pad A. The processor can be a microprocessor such as a single-chip microcomputer and a DSP. At the same time, a system working indicator light 2 and a power-off plug 8.1 are provided on the chest compression auxiliary pad A. The sounder and the visual prompter are both arranged on the chest compression auxiliary pad A. On the auxiliary pad A, in this embodiment, the generator adopts a buzzer 5, and the visual prompter adopts an indicator light. In addition, in this embodiment, three compression frequency indicator lights 3 are set on the chest compression auxiliary pad A. If the compression frequency is within the optimal compression frequency range, the compression frequency indicator light 3 in the middle position will light up (referred to as the middle light) green light. If it is 10% outside the optimal compression frequency range, the middle light will light up yellow light. If it is higher than 10%, the middle light will light up red light. The compression frequency indicator light 3 on the left position indicates when the compression frequency is too slow, and the compression frequency indicator light 3 on the right position indicates when the compression frequency is too fast. Here, the sound generator and the visual prompter can be selected as needed. For example, in this embodiment, the buzzer 5 can also be replaced by an integrated voice module, and the compression frequency indicator light 3 can also be replaced by a display screen.

[0038] like Figures 3 to 5 As shown, the chest compression auxiliary pad A and the auxiliary plate are docked and installed through matching slide rails, including the first slide rails 7 on both sides of the chest compression auxiliary pad A and the second slide rails 9 on the inner side of the auxiliary plate. The two slide rails are designed as matching tooth structures, so that when assembled, the first slide rail 7 and the second slide rail 9 are embedded together to achieve reliable installation. It should be noted that the tooth structure here is only an example, and the form of the slide rail is not limited to the form shown in this embodiment. The structures that can achieve reliable docking in the current prior art can be used for the docking installation of the chest compression auxiliary pad A and the auxiliary plate of the present invention.

[0039] like Figure 5 As shown, the position-limiting auxiliary support structure B includes a slide bar 10, an auxiliary plate is slidably mounted on the slide bar 10, a position-limiting assembly is mounted on the upper and lower ends of the slide bar 10, and a detection assembly is arranged on the position-limiting assembly. The position-limiting auxiliary support structure B also includes a spring 11, which is sleeved on the slide bar 10, the bottom of the spring 11 is fixedly connected to the slide bar 10, and the top of the spring 11 is fixedly connected to the auxiliary plate.

[0040] The limit assembly includes an upper limit plate and a lower limit plate, which are respectively arranged at both ends of the slide bar 10, and the upper limit plate and the lower limit plate are respectively provided with an upper limit contact 12.1 and a lower limit contact 12.2 for touching and limiting the upward and downward movement range of the auxiliary plate. The detection assembly includes a touch sensor arranged on the limit assembly, and when the auxiliary plate moves to the upper and lower maximum travel positions of the slide bar 10, the auxiliary plate contacts the touch sensor. It should be noted here that: in this embodiment, the touch sensor is integrated on the upper limit contact 12.1 and the lower limit contact 12.2. In some other embodiments, the touch sensor may not be integrated with the upper limit contact 12.1 and the lower limit contact 12.2, and the touch sensor may be independently arranged near the limit contact and the lower limit contact 12.2, as long as the upward and downward movement process of the auxiliary plate is detected.

[0041] like Figure 6 As shown, the adaptive base support structure C includes a base 15, a support sleeve and a lifting rod 13. The support sleeve is installed on the base 15. The lifting rod 13 can be installed in the support sleeve in a lifting manner. The top of the lifting rod 13 is provided with a mounting interface for connecting with the position-limiting auxiliary support structure B. The base 15 can be in the form of a suction cup, so that when the ground is a smooth ground such as marble, the adaptive base support structure C can be fixed to the ground position by the suction cup. The lifting rod 13 adopts a toothed structure, so that a height fixing-releasing structure 14 is configured on the support sleeve. In this embodiment, the height fixing-releasing structure 14 can be in the form of a triangular block and a knob. The triangular block matches the toothed structure on the lifting rod 13. When the height needs to be adjusted, the knob is turned to separate the triangular block from the lifting rod 13, change the height of the lifting rod 13, and then the triangular block is locked with the lifting rod 13 by the knob. It should be understood that other lifting structures in the prior art are applicable to the adaptive base support structure C of this application, and its purpose is to adjust the height of the position-limiting auxiliary support structure B according to different body shapes.

[0042] In addition, the mounting interface connecting the top of the lifting rod 13 and the position-limiting auxiliary support structure B adopts a spiral interface, and the top of the lifting rod 13 is provided with a thread, and the lower position-limiting plate of the position-limiting auxiliary support structure B is provided with a matching screw hole. In order to achieve effective support of the position-limiting auxiliary support structure B, each position-limiting auxiliary support structure B can be equipped with two adaptive base support structures C for support, so that the entire chest compression auxiliary device is provided with four adaptive base support structures C. It should be noted that: when the overall width of the position-limiting auxiliary support structure B is not very wide, each position-limiting auxiliary support structure B can also be equipped with only one adaptive base support structure C for support, which can be set according to actual conditions.

[0043] like Figure 7As shown, the interactive component also includes a communication interface 6 for connecting to an external limb lead ECG monitor D and an indicator for displaying ECG monitoring results. The limb lead ECG monitor D includes an upper limb lead first electrode clip 16.1, an upper limb lead second electrode clip 16.2, a lower limb lead electrode clip 17 and a communication data plug 18, and the communication data plug 18 communicates with the communication interface 6. The limb lead ECG monitor D has its own power supply and processor. The communication interface 6 and the indicator for displaying ECG monitoring results are arranged on the chest compression auxiliary pad A. The indicator is in the form of an indicator light, and then as shown in FIG. Figure 2 In this embodiment, an ECG monitoring indicator light 4 is provided on the chest compression auxiliary pad A. Three ECG monitoring indicator lights 4 are also provided. The three ECG monitoring indicator lights 4 are displayed synchronously. If the ECG is abnormal, the indicator light is red, and if the ECG is normal, the indicator light is green. The rescuer can end the chest compression rescue accordingly. Of course, the number of ECG monitoring indicator lights 4 here can be set as needed (for example, only one indicator light can be set). Of course, the indicator may not be in the form of an indicator light, but may also be a voice prompter or a display screen, etc. The purpose is to achieve the interaction of ECG monitoring results. The commonly used interaction methods in the prior art can be applied here. When the limb lead ECG monitor D communicates with the chest compression auxiliary pad A, only the normal / abnormal states are sent to avoid communication interference, save communication resources, and improve communication efficiency.

[0044] The working principle of the chest compression auxiliary device of the present invention is:

[0045] (1) Rapid deployment

[0046] The present invention designs compression auxiliary pads of various sizes to fit patients of different body shapes.

[0047] When an emergency occurs, the rescuer selects a chest compression auxiliary pad A that is suitable for the patient's body width and connects it to the position-limiting auxiliary support structure B through the first slide rail 7. Use the height fixing-releasing structure 14 to unlock and adjust the height of the adaptive base support structure C to the maximum. Connect the lifting rod 13 of the adaptive base support structure C to the position-limiting auxiliary support structure B through a thread. If the ground is a smooth ground such as marble, the suction cup base 15 can be used to keep the device fixed to the ground.

[0048] After the device is installed, the rescuer places the device above the patient's chest, adjusts the height of the limiting auxiliary support structure B so that the chest compression auxiliary pad A is in close contact with the patient's chest, and the rescuer pulls out the power-off plug 8.1. The system working indicator light 2 turns green, and the buzzer 5 prompts the rescuer to start compression.

[0049] (2) Chest compressions

[0050] The buzzer 5 emits a prompt tone at a frequency of 100 to 120 times per minute, and the rescuer performs chest compression according to the prompt tone. During compression, the chest compression auxiliary pad A moves back and forth between the upper limit contact 12.1 and the lower limit contact 12.2, and the upper limit contact 12.1 and the lower limit contact 12.2 are respectively connected to the chest compression auxiliary pad A once and recorded as one compression. The spring 11 provides rebound assistance to assist the rescuer to return to the reference height after each compression to ensure the depth of each compression. The processor records the rescuer's compression frequency through the compression interval. If the compression frequency is within the optimal compression frequency range, the compression frequency indicator 3 in the middle position is lit (referred to as the middle light) green light, if it is 10% outside the optimal compression frequency range, the middle light is lit yellow light, and if it is higher than 10%, the middle light is lit red light, the compression frequency indicator 3 on the left position indicates when the compression frequency is too slow, and the compression frequency indicator 3 on the right position indicates when the compression frequency is too fast.

[0051] (3) ECG monitoring

[0052] If conditions permit, the auxiliary device can be used in conjunction with a limb lead ECG monitor D, which provides more accurate vital sign status monitoring for chest compression through ECG monitoring. When in use, the rescuer clamps the upper limb lead first electrode clip 16.1 and the upper limb lead second electrode clip 16.2 on the patient's left and right wrists, respectively, and clamps the lower limb lead electrode clip 17 on the patient's lower limb ankles. The communication data plug 18 is connected to the communication interface 6 on the chest compression auxiliary pad A. The limb lead ECG monitor D has its own power supply and processor, and only sends two states, normal / abnormal, when communicating with the chest compression auxiliary pad A to avoid communication interference, save communication resources, and improve communication efficiency. After the limb lead ECG monitor D is installed, the ECG monitoring indicator light 4 lights up. If the ECG is abnormal, the indicator light is red, and if the ECG is normal, the indicator light is green, and the rescuer can end the chest compression rescue accordingly.

[0053] The chest compression auxiliary device of the present invention is provided with a limiting auxiliary support structure B, which can limit the up and down movement range of the chest compression auxiliary pad A, thereby providing auxiliary support for the compression depth. In addition, the device is provided with a detection component for detecting the up and down movement frequency of the auxiliary plate, and exchanges information through an interactive component to provide auxiliary support for the chest compression frequency, thereby ensuring that the effective compression depth and compression frequency are always maintained during the chest compression process. The chest compression auxiliary pad A, the limiting auxiliary support structure B and the adaptive base support structure C of the chest compression auxiliary device are all assembled structures, which can be quickly deployed and are suitable for emergency scenarios such as homes and public places.

[0054] The above embodiments are merely examples and do not limit the scope of the present invention. These embodiments can also be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the technical concept of the present invention.
