Description

Technical Field

[0001] The present invention relates to the technical field of cardiopulmonary resuscitation, and more specifically, to a cardiopulmonary resuscitation pressing mechanism and a pressure monitoring and control system thereof. Background Art

[0002] At present, cardiopulmonary resuscitation is becoming more and more popular in the emergency treatment of patients with cardiac arrest. With the deepening of clinical application and academic research, cardiopulmonary resuscitation technology has put forward high-quality cardiopulmonary resuscitation requirements.

[0003] At present, the clinical rules for performing cardiopulmonary resuscitation are mostly derived from a large amount of clinical manual cardiopulmonary resuscitation data. The key points of compression are: (1) compression depth, which is recommended to be greater than 5 cm for adults; (2) compression frequency greater than 100 times / minute; (3) ventilation mode, continuous compression-ventilation mode, 30:2 and 15:2 modes. Existing cardiopulmonary resuscitation equipment is designed and manufactured around the above clinical requirements.

[0004] In order to achieve effective blood circulation during cardiopulmonary resuscitation, compression pressure is an important parameter. Among the existing cardiopulmonary resuscitation equipment, there are few devices with pressure sensors on the compression head. In order to solve the compression pressure feedback, the prior art proposes a solution of an external pressure feedback device. For example, the utility model patent with authorization announcement number CN222033047U discloses a cardiopulmonary resuscitation compression assistant, the invention patent with authorization announcement number CN111419680B discloses a compression feedback device and a compression device, the invention patent with application publication number CN115689390A discloses a cardiopulmonary resuscitation evaluation method and evaluation system suitable for remote training scenarios, and the utility model patent with authorization announcement number CN217982636U discloses a cardiopulmonary resuscitation compression guidance feedback device. The characteristics of the above patents are that the pressure feedback is separated from the cardiopulmonary resuscitation equipment, there is no effective control of the cardiopulmonary resuscitation equipment, and there is a lack of targeted analysis of the feedback pressure data to assist the rescuer to take corresponding measures, thereby improving the rescue rate.

[0005] Therefore, it is necessary to propose a cardiopulmonary resuscitation compression mechanism and a pressure monitoring and control system thereof to at least partially solve the problems existing in the prior art. Summary of the invention

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0051] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0052] like Fig. 9 As shown, the present invention provides a cardiopulmonary resuscitation pressing mechanism, comprising:

[0053] The pressing rod 1 is arranged in the cylinder 11 in the form of axial reciprocating motion;

[0054] A pressing head 30 is provided at one end of the pressing rod 1 extending out of the cylinder 11, and a pressure sensor 3 is provided inside the pressing head 30;

[0055] Transmission mechanism: the pressing rod 1 is connected in the cylinder 11 through the transmission mechanism, and the transmission mechanism is connected to the driving part 14 arranged outside the cylinder 11.

[0056] It also includes: a drag chain 8, one end of which is connected to the pressing rod 1, and the other end is connected to the cylinder 11;

[0057] The signal line 12 is arranged in the drag chain 8 , one end of the signal line 12 passes through the pressing rod 1 and the pressing head 30 , and the other end is connected to the pressure sensor 3 .

[0058] Among them, the transmission mechanism includes: a driving wheel 15 connected to the output end of the driving part 14, a synchronous belt 16, a driven wheel 17 connected to the driving wheel 15 through the synchronous belt 16, a screw rod 18 coaxially arranged with the driven wheel 17, and a nut 19 threadedly connected to the screw rod 18, and the nut 19 is fixedly connected to the pressing rod 1.

[0059] An angular contact bearing 20 is disposed on the outer side of the screw rod 18 . The angular contact bearing 20 is disposed in the cylinder barrel 11 via a bearing fixing member 21 . A bearing baffle 22 is disposed on the top of the angular contact bearing 20 .

[0060] The driving part 14 drives the driving wheel 15 to rotate, so that the synchronous belt 16 drives the driven wheel 17 to rotate, and the driven wheel 17 rotates to drive the screw rod 18 coaxially arranged therewith, and the nut 19 is limitedly connected in the cylinder 11 so that it cannot rotate and can only move linearly up and down. Therefore, the rotation of the screw rod 18 causes the nut 19 to drive the pressing rod 1 to reciprocate up and down, and the patient is resuscitated by the pressing head 30. During the process of cardiopulmonary resuscitation, the pressure sensor 3 detects the pressure value of the pressing process in real time. The outer side of the cylinder 11 is also provided with a position detection plate and a position detection sheet; they are used to assist in detecting the position of the pressing head 30 when it is working.

[0061] like Figure 1 As shown, the present invention provides a pressure monitoring and control system for a cardiopulmonary resuscitation pressing mechanism, comprising:

[0062] An acquisition module is used to detect and record chest compression data in real time during the chest compression process;

[0063] The compression data include: the maximum pressure during chest compression and the rebound pressure during chest rebound;

[0064] An analysis module, used to analyze the compression data and obtain analysis results;

[0065] The control module is used to control the cardiopulmonary resuscitation compression mechanism according to the maximum pressure and rebound pressure detected in real time.

[0066] The control module can also control the cardiopulmonary resuscitation compression mechanism based on the analysis results.

[0067] It also includes: a display module, which is used to output and display the analysis results of the analysis module, so as to facilitate the rescuer to view and prompt.

[0068] When performing cardiopulmonary resuscitation on a patient through the cardiopulmonary resuscitation pressing mechanism, the pressing head 30 is first brought into contact with the patient's chest, the initial pressure of the contact between the two is adjusted, and then the pressing depth parameter is set, the driving unit is started, and the pressing rod is controlled to reciprocate up and down, and the patient is pressed by the pressing head 30. The pressure sensor is used to feed back the detected pressure to the acquisition module in real time, and the acquisition module records the compression data of the chest compression process;

[0069] The detection of the maximum pressure during chest compression is used to determine and adjust the compression depth during cardiopulmonary resuscitation to ensure effective compression; the detection of the rebound pressure during chest rebound is used to reflect whether the chest rebounds completely after compression, that is, when the compression head 30 returns to the initial position, whether the patient's chest is in contact with the compression head 30 after rebounding, so as to control the cardiopulmonary resuscitation compression mechanism to prevent the distance between the chest and the compression head 30, and prevent the compression head 30 from impacting the chest;

[0070] The analysis module can analyze the compression data and output the analysis results, thereby providing effective clinical data for rescuers, making it easier for them to take corresponding measures and improve the rescue rate.

[0071] like Figure 2 and Figure 4 As shown, in one embodiment, the analysis module includes:

[0072] The first monitoring unit obtains the compression peak-to-peak value according to the maximum pressure and rebound pressure of each compression;

[0073] The first analysis unit analyzes whether the current pressing is valid according to the peak-to-peak values ​​of the current pressing and the last valid pressing.

[0074] The compression peak-to-peak value is the difference between the maximum pressure and the rebound pressure. The maximum pressure refers to the pressure value of the patient's chest cavity fed back by the pressure sensor when the compression head 30 is at the deepest compression position. The rebound pressure refers to the pressure value of the patient's chest cavity fed back by the pressure sensor when the compression head 30 returns to the initial position.

[0075] The peak-to-peak value of compression is used to indicate whether effective compression is performed during cardiopulmonary resuscitation. If the compression is interrupted, the compression head 30 does not fit the patient's chest, or the patient's chest collapses during the compression process, the current peak-to-peak value of compression will be significantly changed compared to the peak-to-peak value of the last effective compression, thereby being able to detect whether the compression is effective, providing a basis for evaluating the effect of cardiopulmonary resuscitation, and improving the level of cardiopulmonary resuscitation treatment.

[0076] like Figure 2 and Figure 4 As shown, in one embodiment, the pressing data further includes: pressing frequency; the analysis module further includes:

[0077] The second monitoring unit obtains a compression frequency-maximum compression pressure curve according to the compression frequency and the maximum pressure during chest compression;

[0078] The second analysis unit analyzes the consistency of the maximum pressure of each compression according to the compression frequency-maximum compression pressure curve.

[0079] By analyzing the consistency of the maximum pressure of each compression, the effectiveness of each compression can be monitored, and whether the consistency of the maximum pressure of each compression meets the standard can be prompted;

[0080] In addition, by analyzing the consistency of the maximum pressure of each compression, when the maximum pressure of the current compression does not meet the standard, the compression depth of the cardiopulmonary resuscitation compression mechanism can be adjusted in time to ensure the effectiveness of subsequent compressions.

[0081] Furthermore, the consistency of the maximum pressure of each compression is determined by the following method:

[0082] Consistency parameter for determining the maximum pressure of each compression Is it less than or equal to the set parameter? If yes, then the consistency of the maximum pressure of the current compression meets the standard; if no, then the consistency of the maximum pressure of the current compression does not meet the standard, and a corresponding prompt is issued;

[0083] Consistency parameter for maximum pressure per compression Obtained by the following formula:

[0084]

[0085] Among them, P imax is the maximum pressure of the ith compression whose consistency meets the standard, n is the total number of compressions, and k is the number of compressions whose consistency of the maximum pressure does not meet the standard.

[0086] Based on the above judgment, the rebound pressure and the peak-to-peak pressure can also be combined to judge whether the current compression is effective, specifically:

[0087] By analyzing the consistency of the maximum pressure of each compression, the effectiveness of each compression can be judged. That is, when the consistency of the maximum pressure of each compression meets the standard, and there is no abnormality in the rebound pressure and the compression peak value, it indicates that the current compression is effective.

[0088] If the consistency of the maximum pressure of each compression does not meet the standard, it indicates that the maximum pressure of the current compression is abnormal, and the current compression is marked. It is also necessary to combine the rebound pressure and the peak-to-peak pressure to further determine whether the current compression is valid; specifically: if the rebound pressure and the peak-to-peak pressure of the current compression are not abnormal, the current compression is a valid compression; if at least one of the rebound pressure and the peak-to-peak pressure of the current compression is abnormal, the current compression is an invalid compression.

[0089] like Figure 2 and Figure 4 As shown, in one embodiment, the analysis module further includes:

[0090] The third monitoring unit obtains a compression frequency-compression rebound pressure curve according to the compression frequency and the rebound pressure when the chest cavity rebounds;

[0091] The third analysis unit analyzes the consistency of the rebound pressure of each pressing according to the pressing frequency-pressing rebound pressure curve.

[0092] By analyzing the consistency of the rebound pressure of each compression, it is possible to monitor and control whether the patient's chest cavity fully rebounds after each compression, thereby determining whether the compression is effective; the rebound pressure is generally set at 0.1kg-0.2kg. After each compression, it is necessary to ensure that the patient's chest cavity fully rebounds, which is especially important for the patient's blood circulation and recovery of breathing.

[0093] In addition, by analyzing the consistency of the rebound pressure of each compression, when the rebound pressure of the current compression does not meet the standard, the pressure of the compression head 30 of the cardiopulmonary resuscitation compression mechanism in contact with the chest cavity can be adjusted in time to ensure the effectiveness of subsequent compressions.

[0094] Furthermore, the consistency of the rebound pressure of each press is determined by the following method:

[0095] Determine whether the consistency parameter ω of the rebound pressure of each press is less than or equal to the set parameter ω 0 If yes, then the consistency of the rebound pressure of the current pressing meets the standard; if no, then the consistency of the rebound pressure of the current pressing does not meet the standard;

[0096] The consistency parameter ω of the rebound pressure for each press is obtained by the following formula:

[0097]

[0098] Among them, P jmin is the rebound pressure of the jth compression whose consistency meets the standard, n is the total number of compressions, and r is the number of compressions whose consistency of the rebound pressure does not meet the standard.

[0099] Based on the above judgment, the maximum pressure and the peak-to-peak pressure can also be combined to judge whether the current compression is effective, specifically:

[0100] By analyzing the consistency of the rebound pressure of each compression, the effectiveness of each compression can be judged. When the consistency of the rebound pressure of each compression meets the standard and there is no abnormality in the maximum pressure and the compression peak-to-peak value, it indicates that the current compression is effective.

[0101] If the consistency of the rebound pressure of each press does not meet the standard, it indicates that the rebound pressure of the current press is abnormal, and the current press is marked. It is also necessary to combine the maximum pressure and the peak-to-peak pressure to further determine whether the current press is valid; specifically: if there are no abnormalities in the maximum pressure and the peak-to-peak pressure of the current press, the current press is a valid press; if at least one of the maximum pressure and the peak-to-peak pressure of the current press is abnormal, the current press is an invalid press.

[0102] In one embodiment, the first analysis unit analyzes the compression peak-to-peak value by:

[0103] Obtain the error value between the peak-to-peak value of the current press and the last valid press, and determine whether the error value is within a set range. If so, the current press is valid, otherwise, the current press is invalid.

[0104] In this embodiment, the analysis and judgment of the compression peak value can determine whether the current compression is effective, thereby detecting the effective compression and providing a basis for the rescuer to evaluate the effect of cardiopulmonary resuscitation.

[0105] In addition, another method for analyzing the compression peak-to-peak value by the first analysis unit is provided, including:

[0106] Obtain the error value between the peak-to-peak value of the current press and the last effective press, and determine whether the error value is within a set range;

[0107] If the error value is within the set range, and the consistency of the maximum pressure and rebound pressure of the current press meets the standard, the current press is valid;

[0108] If the error value is within the set range, and the consistency of the maximum pressure and rebound pressure of the current press does not meet the standard, the current press is invalid;

[0109] If the error value is not within the set range, the current press is invalid.

[0110] In the above analysis method, the compression peak-to-peak value, maximum pressure and rebound pressure are combined to further analyze whether the compression is effective, so as to avoid misjudgment of the compression peak-to-peak value in the case of invalid compression when the maximum pressure and rebound pressure decrease or increase at the same time, thereby improving the accuracy of the compression effectiveness analysis.

[0111] like Figure 6-Figure 7 As shown, in one embodiment, the compression data further includes: compression pressure and compression depth; the analysis module further includes:

[0112] The fourth monitoring unit obtains a compression pressure-compression depth curve according to the compression pressure and the compression depth;

[0113] The fourth analysis unit analyzes whether an abnormality occurs in the current pressing process according to the pressing pressure-pressing depth curve, and issues an abnormality reminder when an abnormality occurs in the current pressing process.

[0114] like Figure 5 As shown in Figure 2, during cardiopulmonary resuscitation, compression pressure and compression depth change periodically with compression frequency. Figure 6 As shown, compression pressure increases with increasing compression depth;

[0115] like Figure 7 The compression pressure-compression depth curve during normal compression is shown, which means that as the compression depth increases, the compression pressure increases linearly, which can also provide feedback on the effectiveness of the compression and reflect the actual situation of the patient's chest during the compression process. For example, Figure 8 As shown, Compression 1 is a standard compression pressure-compression depth curve, and Compression 2 is a compression pressure-compression depth curve when a fracture occurs. It can be seen that the linearity will decline rapidly, and the compression pressure will decrease rapidly, thereby issuing a prompt to remind the rescuer to quickly take corresponding measures.

[0116] like Figure 3 As shown, in one embodiment, the control module includes:

[0117] A first judgment unit, used to judge whether the maximum pressure during chest compression is within a first pressure range, and obtain a first judgment result;

[0118] The first control unit adjusts the compression depth of the cardiopulmonary resuscitation compression mechanism when the first judgment result is no.

[0119] The first pressure range is a preset reference range of the maximum pressure allowed by the patient's chest cavity. If the maximum pressure reaches the maximum value of the first pressure range and the compression depth of the cardiopulmonary resuscitation compression mechanism has not reached the preset compression depth parameter, the compression is stopped and the compression depth at this time is used as the compression depth parameter for the next compression; when the compression depth of the cardiopulmonary resuscitation compression mechanism reaches the preset compression depth parameter and the maximum pressure has not reached the minimum value of the first pressure range, the compression head 30 is continuously controlled to move downward until the maximum pressure is within the first pressure range, the compression is stopped and the compression depth at this time is used as the compression depth parameter for the next compression;

[0120] The maximum pressure can be used to determine and adjust the compression depth to ensure the effectiveness of the compression while reducing the risk of fractures in patients due to excessive pressure.

[0121] like Figure 3 As shown, in one embodiment, the control module further includes:

[0122] A second judgment unit is used to judge whether the rebound pressure of the chest cavity during rebound is within a second pressure range to obtain a second judgment result;

[0123] The second control unit adjusts the pressure of the pressing head 30 of the cardiopulmonary resuscitation pressing mechanism in contact with the chest cavity when the second judgment result is no.

[0124] The initial pressure is generally set to be less than or equal to 0.1 kg. When the initial pressure is set to 0.1 kg, the second pressure range corresponding to the rebound pressure is set to 0.1 kg-0.2 kg.

[0125] When the pressing head 30 returns to its initial position and the patient's chest rebounds, if the pressure between the chest and the pressing head 30 is less than the minimum value of the second pressure range, that is, less than 0.1 kg, it indicates that the chest has not fully rebounded and the initial position of the pressing head 30 needs to be adjusted to adjust the pressure between the pressing head 30 and the chest to prevent impact injuries.

[0126] like Figure 3 As shown, in one embodiment, the control module further includes:

[0127] The third control unit controls the pressure between the compression head 30 and the chest cavity to be zero during ventilation.

[0128] Since cardiopulmonary resuscitation consists of two stages, namely, compression and ventilation, during ventilation, the pressure between the compression head 30 and the patient's chest cavity needs to be completely released, that is, no pressure is generated on the chest cavity. In this case, the compression head 30 needs to move upward beyond the set distance of its initial position. Since the chest cavity rises and falls during ventilation, the set distance can ensure that there is no contact between the chest cavity and the compression head 30 during ventilation.

[0129] In one embodiment, it further includes: a cardiopulmonary resuscitation assessment module, which obtains a cardiopulmonary resuscitation assessment result according to the percentage of the time of compression during the cardiopulmonary resuscitation to the entire cardiopulmonary resuscitation time;

[0130] Among them, when the percentage is greater than or equal to 80%, the cardiopulmonary resuscitation assessment result is that the cardiopulmonary resuscitation meets the requirements, and when the percentage is less than 80%, the cardiopulmonary resuscitation assessment result is that the cardiopulmonary resuscitation does not meet the requirements;

[0131] Among them, the time for implementing compression during cardiopulmonary resuscitation is: the effective compression operation time of the cardiopulmonary resuscitation compression mechanism.

[0132] The effective pressing operation time is the sum of the times of multiple effective pressings. The judgment of effective pressing can be based on the various methods in the aforementioned embodiments, for example: judging the effective pressing by one or more combinations of analyzing the consistency of maximum pressure, analyzing the consistency of rebound pressure, and analyzing the peak-to-peak value of pressing, or judging the effective pressing by combining the analysis of the peak-to-peak value of pressing, maximum pressure and rebound pressure.

[0133] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0134] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
