Abstract
Description
Technical Field
[0001] This invention relates to the field of medical technology, and in particular to a chest and abdominal compression device, a compression system and method based on big data. Background Technology
[0002] Painless gastroscopy and colonoscopy refer to gastroscopy and colonoscopy performed under intravenous anesthesia, during which the patient loses consciousness and pain sensation. Intravenous anesthesia refers to anesthesia administered solely via intravenous medication to preserve the patient's spontaneous breathing as much as possible, without invasive airway management. Invasive airway management refers to airway management measures such as laryngeal mask airway insertion or endotracheal intubation, which are usually used for patients who do not breathe spontaneously or require airway protection.
[0003] During painless gastroscopy and colonoscopy, although muscle relaxants are not used, patients often experience varying degrees of respiratory depression due to intravenous anesthetic drugs (propofol and opioids). Respiratory depression manifests as a slowed or stopped breathing rate, weakened breathing strength, and upper airway obstruction caused by posterior displacement of the tongue. Respiratory depression can lead to varying degrees of hypoxia, potentially damaging the brain or heart. Current methods for managing and preventing respiratory depression include: increasing the inhaled oxygen concentration via nasal cannula before and during anesthesia; and the physician lifting the patient's jaw to relieve posterior displacement of the tongue. There are currently no good solutions for suppressing respiratory rate and breathing strength.
[0004] In 2021, the inventors (in their study "Prevention of Respiratory Depression Caused by Propofol Sedation in Patients Undergoing Painless Gastroscopy") discovered that chest, abdominal, or combined chest and abdominal compressions during intravenous anesthesia significantly reduced the risk of decreased blood oxygen saturation and increased diaphragmatic movement intensity, with the chest compression group exhibiting the greatest diaphragmatic activity. In 2023, the inventors conducted further clinical research (in their study "Modified Manual Chest Compression for Prevention and Treatment of Respiratory Depression in Patients Under Deep Sedation During Upper Gastrointestinal Endoscopy: Two Randomized Controlled Trials"), finding that manual compression of the upper lower chest wall of patients (in a lateral decubitus position) after intravenous anesthesia (approximately 2.5-3.5 kgf, compression frequency approximately 2 times / second, 20 compressions) significantly reduced the time when blood oxygen saturation was below 95% (40s vs. 91s) and promoted increased diaphragmatic movement (confirmed by diaphragmatic ultrasound).
[0005] The mechanism by which chest and abdominal compressions reduce the risk of decreased blood oxygen saturation is not yet clear, but it may be related to increased diaphragmatic movement caused by stimulating respiratory muscles such as the diaphragm to send afferent impulses.
[0006] While chest and abdominal compressions help reduce the risk of hypoxia in patients undergoing intravenous anesthesia, in actual clinical practice, anesthesiologists face heavy workloads and may need to monitor multiple patients simultaneously, leaving them little time to perform chest and abdominal compressions on every anesthetized patient. Furthermore, some patients require prolonged examinations, and respiratory arrest can occur at any time, not just during the induction phase.
[0007] Therefore, a chest and abdominal compression device integrating respiratory monitoring and treatment is needed to assist anesthesiologists in conveniently performing chest or abdominal compressions on patients experiencing respiratory depression after anesthesia, promoting the rapid recovery of spontaneous breathing, and reducing the occurrence of hypoxemia and its related complications. Furthermore, by monitoring the patient's respiratory status in real time through a vital signs monitoring module, targeted early compressions can be performed to prevent and treat respiratory depression that occurs after intravenous anesthesia. Summary of the Invention
[0008] The purpose of this invention is to provide a chest and abdominal compression device, an automatic compression system, and a control method to assist anesthesiologists in performing chest or abdominal compressions on patients under intravenous anesthesia, stimulating diaphragmatic movement, thereby reducing the risk of hypoxia.
[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A chest and abdominal compression device includes a power supply, a housing, a reciprocating mechanism, a compression block, a microprocessor, and a drive unit. The reciprocating motion mechanism includes a first gear disk, a transmission rod, a slider, and a slider channel. An external gear is provided on the outer edge of the first gear disk. The first gear disk can rotate around its shaft, which is fixed to the housing. A convex shaft is provided on one side of the first gear disk. The convex shaft is rotatably connected to a first shaft hole at one end of the transmission rod. A second shaft hole at the other end of the transmission rod is rotatably connected to a slider convex shaft at the tail end of the slider. The sliding part of the slider is located within the slider channel, and the slider can only reciprocate along the axial direction of the slider channel. The head end of the slider is connected to a pressing block. When the pressing block is closest to the slider channel, the first gear disk is located between the head and tail ends of the slider. The driving device includes a drive motor and a first drive gear. The first drive gear is connected to the shaft of the drive motor and meshes with a gear on the outer edge of the first gear disk. The rotation of the drive motor drives the first drive gear to rotate, thereby driving the first gear disk to rotate. The convex shaft on the first gear disk drives the transmission rod to move, thereby driving the slider to perform linear reciprocating motion through the second shaft hole at the other end of the transmission rod and the slider convex shaft.
[0010] By placing the gear disk between the head and tail ends of the slider, the thickness of the equipment can be greatly reduced, thus enabling an efficient reciprocating motion structure within a limited space.
[0011] Furthermore, a second gear disk is provided on the side of the slider that is symmetrical to the first gear disk. The second gear disk, along with its connected disk cam, transmission rod, slider cam, and the first gear disk and its corresponding connected structure are mirror images of the slider. The initial positions of the disk cams on the first and second gear disks are at the same distance from the slider. The second gear disk is provided with a corresponding second drive gear, which is driven by a first motor. The first and second drive gears work synchronously, thereby superimposing the forces exerted on the slider by the first and second gear disks. The force superposition effect of the symmetrical dual-gear drive and the lateral force balance can reduce slider wear and extend the equipment life.
[0012] Furthermore, the first drive gear and the second drive gear are driven by the same shaft of the same motor to ensure the synchronicity of gear operation.
[0013] Furthermore, the two sides of the housing of the pressing device are respectively connected to the first strap and the second strap. The pressing device can be fixed in the appropriate position on the patient's chest and abdomen through the first strap and the second strap. The ends of the first strap and the second strap are glued for fixation.
[0014] Furthermore, the pressing device is provided with a corresponding base plate, and strap rods are provided on both sides of the base plate. The straps can be fixed at different axial positions of the strap rods to fix the pressing device in different positions of the patient.
[0015] Furthermore, a power supply line passes through the substrate, and after traveling inside the first bundle, the power supply line is connected to the pressing device. The power supply line is spiral-shaped to accommodate different lengths.
[0016] Furthermore, a diaphragm is provided below the pressing block. The diaphragm is elastic, and the closed space formed by the diaphragm and the shell is connected to the air supply pipe located outside the shell through the air supply channel. When the closed space is inflated, the distance between the pressing block and the human body can be increased, thereby reducing the pressing force of the pressing device. Correspondingly, when the closed space is deflated, the distance between the pressing block and the human body can be reduced, thereby increasing the pressing force of the pressing device. By adjusting the gas in the closed space, the pressing force can be infinitely adjusted.
[0017] The present invention also provides a chest and abdominal compression system based on big data, which, in addition to any of the chest and abdominal compression devices mentioned above, also includes a vital sign monitoring module and a big data vital sign analysis module. The vital sign monitoring module can transmit vital sign monitoring data to the big data vital sign analysis module. After analyzing the vital sign data, the big data vital sign analysis module generates instructions that can control the chest and abdominal compression device. The microprocessor of the chest and abdominal compression device automatically adjusts the working parameters of the compression device and executes them according to the input instruction signal.
[0018] Furthermore, the vital signs monitoring module is an electrocardiogram (ECG) monitor. The compression device automatically adjusts its operating parameters, such as compression force, compression frequency, and compression duration, based on the respiratory rate, respiratory intensity, blood oxygen saturation, and heart rate monitored by the ECG monitor.
[0019] Furthermore, the vital signs monitoring module can also be an electronic stethoscope, which includes a pickup cavity, a condenser microphone, a stethoscope power supply device, a stethoscope processor, and a stethoscope signal transmission device. The electronic stethoscope is placed on the patient's chest to monitor the lungs or placed on the neck to monitor the trachea. After the monitored sound signal is processed by the big data vital signs analysis module, the big data vital signs analysis module sends the corresponding compression command to the compression device.
[0020] Furthermore, the vital signs monitoring module can also be a combination of an electrocardiogram monitor and an electronic stethoscope.
[0021] Furthermore, the edge of the contact surface between the electronic stethoscope and the patient is a double-concave cap-shaped protrusion made of elastic material, so that the electronic stethoscope can be fixed to the patient's neck by creating negative pressure in the contact space with the patient; the contact surface between the electronic stethoscope and the patient is equipped with an infrared monitoring device to monitor whether the electronic stethoscope has fallen off.
[0022] This invention also provides a big data-based pressure system control method for controlling a big data-based pressure system, comprising the following steps: a. Acquisition of vital signs data: The vital signs monitoring module monitors the patient's vital signs data in real time and transmits it to the big data vital signs analysis module; b. Vital signs data analysis: The big data vital signs analysis module analyzes the monitored vital signs data to determine whether the patient needs chest or abdominal compression therapy. If it is determined that the patient needs compression therapy, the module will determine the force, frequency, and duration of chest or abdominal compressions. c. Instruction generation: Generate a series of instructions from the compression parameters in step b and transmit them to the chest and abdomen compression device. d. Execution instructions: The microprocessor of the chest and abdominal compression device executes the compression instructions from the big data vital signs analysis module, and controls the drive device to drive the operation of the compression device; e. End of instruction: The press instruction ends when the operating time of the drive device reaches the duration specified by the press instruction, or when the operator performs the operation manually.
[0023] The Big Data Vital Signs Analysis module is a data analysis module based on training with big data on vital signs. The training data can come solely from monitoring data from an electrocardiogram (ECG) monitor, including but not limited to: respiratory rate, respiratory strength, blood oxygen saturation, heart rate, and blood pressure; it can also come solely from audio data from a stethoscope, including recordings from a standard stethoscope and monitoring data from an electronic stethoscope; or it can come from both types of data simultaneously. The final output of the data analysis is: whether the patient needs chest or abdominal compression therapy; and the operating parameters of the chest and abdominal compression device. Whether compression therapy is needed and the parameters for compression therapy can be determined solely from ECG monitor data or electronic stethoscope data, or jointly from both types of data. The output sub-results of the ECG monitor data include: 1. Degree of hypoxia; 2. Degree of hypoxia; 3. Respiratory rate and its trend; 4. Respiratory strength (judged by the respiratory curve and its trend). The output sub-results of the electronic stethoscope data include: 1. Respiratory rate and its trend; 2. Respiratory strength and its trend; 3. Possible causes affecting respiration. The data from the electrocardiogram monitor and electronic stethoscope are judged and labeled by professional physicians and divided into training set and test set. The training set is used by the big data vital signs analysis module for learning, while the test set is used to test the big data module.
[0024] The beneficial effects of this invention are as follows: The chest and abdominal compression device provided by this invention can be fixed to a designated location on the patient before anesthesia, such as the upper abdomen below the xiphoid process or the lateral chest, by means of a strap or other means. After the patient undergoes intravenous general anesthesia, the anesthesiologist can directly perform compressions on the patient through the corresponding button to stimulate the patient's respiratory recovery and reduce the risk of hypoxemia. In addition, through a vital sign monitoring module, such as an electrocardiogram monitor or an electronic stethoscope, the patient's vital signs can be monitored in real time. When the patient experiences respiratory depression, the corresponding compression work is automatically performed, increasing the accuracy of the compression indications and reducing the workload of the anesthesiologist.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Example 1 Please combine Figure 1-7This invention provides a chest and abdominal compression device for compressing the chest and abdomen of a patient to alleviate respiratory depression caused by intravenous anesthesia. It includes a power supply device, a housing 1, a reciprocating mechanism, a compression block 3, a microprocessor 4, and a drive device. The reciprocating mechanism includes a first gear disk 21, a transmission rod 22, a slider 23, and a slider channel 26. An external gear is provided on the outer edge of the first gear disk 21. The first gear disk 21 is rotatable around a disk shaft 24, which is fixed to the housing 1. A disk convex shaft 25 is provided on one side of the first gear disk 21. The disk convex shaft 25 is a protruding shaft on the side of the first gear disk 21 facing the slider 23. The disk convex shaft 25 is rotatably connected to a first shaft hole 29 at one end of the transmission rod 22, allowing the transmission rod 22 to rotate along the disk convex shaft 25. A second shaft hole at the other end of the transmission rod 22 is rotatably connected to a slider convex shaft 28 at the tail end of the slider 23, allowing the transmission rod 22 to rotate along the slider convex shaft 28. The slider 23 rotates; the sliding part of the slider 23 is located inside the slider channel 26, and the slider 23 can only reciprocate along the axial direction of the slider channel 26; the head end of the slider 23 is connected to the pressing block 3. When the pressing block 3 is closest to the slider channel 26, the first gear disk 21 is located between the head end and the tail end of the slider 23, and the disk convex shaft 25 is located between the slider convex shaft 28 and the sliding disk shaft 24. The rotation of the first gear disk 21 will pull the slider 23 towards the pressing block 3; when the pressing block 3 is farthest from the slider channel 26, the disk shaft 24 is located between the slider convex shaft 28 and the disk convex shaft 25. The rotation of the first gear disk 21 will pull the slider 23 towards the pressing block 3, thus forming a reciprocating motion. The driving device includes a drive motor and a first drive gear 271. The first drive gear is connected to the shaft of the drive motor. The first drive gear 271 meshes with the gear on the outer edge of the first gear disk 21. The rotation of the drive motor drives the first drive gear 271 to rotate, thereby driving the first gear disk 21 to rotate. The disk cam 25 on the first gear disk 21 drives the transmission rod 22 to move, thereby driving the slider 23 to perform linear reciprocating motion through the second shaft hole 29 at the other end of the transmission rod 22 and the slider cam 28.
[0029] The pressing block 3 is a device for pressing the patient. The pressing block 3 reciprocates under the drive of the reciprocating motion mechanism, repeatedly pressing the designated part of the patient. A layer of soft material can be set on the force-bearing surface of the pressing block 3 to make the force on the pressed area of the patient more even, thereby reducing the possibility of force injury.
[0030] A second gear disk 211 is provided on the side of the slider 23 opposite to the first gear disk 21. The second gear disk 211, the disk cam shaft, the transmission rod, the slider cam shaft connected thereto, and the first gear disk 21 and the corresponding structure connected to the first gear disk 21 are distributed in a mirror image relative to the slider. The initial positions of the disk cam shafts 25 on the first gear disk 21 and the second gear disk 211 are at the same distance from the slider 23. The second gear disk 211 is provided with a corresponding second drive gear 272, which is driven by a first motor. The first drive gear 271 and the second drive gear 272 work synchronously, so that the forces exerted by the first gear disk 21 and the second gear disk 211 on the slider 23 are superimposed.
[0031] The aforementioned symmetrical drive structure not only allows the driving force to be superimposed, but also reduces the friction caused by uneven force on the slider 23 in the lateral direction, resulting in higher driving efficiency and increased service life of the structure.
[0032] The first drive gear 271 and the second drive gear 272 are driven by the same shaft of the same motor to ensure the synchronicity of the gear operation.
[0033] The reciprocating motion principle of the pressing device is based on Figure 6 As shown: Unlike traditional reciprocating motion mechanisms, the first gear disk 21 is located inside the movement range of the reciprocating slider 23. That is, the disk's convex shaft 25 is always located at the end of the slider's convex shaft 28 near the pressing block 3. This mechanism is advantageous for achieving reciprocating motion within a limited thickness or space. Assuming the initial position is when the pressing block 3 is closest to the slider channel 26, the first gear disk 21, driven by the motor, rotates counterclockwise. This rotation, via the disk's convex shaft 25, the transmission rod 22, and the slider's convex shaft 28, pulls the slider 23 downwards along the slider channel 26. The slider channel 26 limits the movement of the slider 23, ensuring that it can only reciprocate along a straight line. When the slider 23 reaches its lowest point, the counterclockwise rotating first gear disk 21 will drive the slider 23 upwards until it reaches its highest point, completing one cycle. This cycle repeats continuously, which is called reciprocating motion. The distance h of the reciprocating motion is equal to twice the distance between the center of the disc cam 25 and the center of the first gear disc 21. The range of the reciprocating motion can be adjusted by adjusting the diameter of the first gear disc 21 and the position of the disc cam 25 from the center.
[0034] The housing 1 of the chest and abdomen compression device is connected to the first strap 61 and the second strap 62 on both sides respectively. The compression device can be fixed at the appropriate left and right position of the patient's chest and abdomen through the first strap 61 and the second strap 62. The ends of the first strap 61 and the second strap 62 are glued and fixed, and their relative position with the strap rod 63 can be adjusted.
[0035] The pressing device is provided with a corresponding base plate 7, and the base plate 7 is provided with strap rods 63 on both sides. The straps can be fixed at different axial positions of the strap rods 63 to fix the pressing device at different axial positions of the patient.
[0036] A power supply line 8 passes through the substrate 7. After traveling inside the first bundle 61, the power supply line 8 is connected to the pressing device. The power supply line 8 is spiral-shaped to accommodate different lengths.
[0037] A diaphragm 9 is provided below the pressing block 3. The diaphragm 9 is elastic. The closed space formed by the diaphragm 9 and the shell is connected to the air supply pipe 92 located outside the shell through the air supply channel 91. When the closed space is inflated, the distance between the pressing block 3 and the human body can be increased, thereby reducing the pressing force of the pressing device. Correspondingly, when the closed space is deflated, the distance between the pressing block 3 and the human body can be reduced, thereby increasing the pressing force of the pressing device. By adjusting the gas in the closed space, the pressing force can be infinitely adjusted.
[0038] The present invention also provides a chest and abdominal compression system based on big data, which, in addition to any of the chest and abdominal compression devices mentioned above, also includes a vital sign monitoring module and a big data vital sign analysis module. The vital sign monitoring module can transmit vital sign monitoring data to the big data vital sign analysis module. After analyzing the vital sign data, the big data vital sign analysis module generates instructions that can control the chest and abdominal compression device. The microprocessor of the chest and abdominal compression device automatically adjusts the working parameters of the compression device and executes them according to the input instruction signal.
[0039] The vital signs monitoring module is an electrocardiogram (ECG) monitor. The compression device automatically adjusts its operating parameters, such as compression force, compression frequency, and compression duration, based on the respiratory rate, respiratory intensity, blood oxygen saturation, and heart rate monitored by the ECG monitor.
[0040] The vital signs monitoring module can also be an electronic stethoscope, which includes a pickup chamber, a condenser microphone, a power supply device, a microprocessor, and a signal transmission device. The electronic stethoscope is placed in the patient's chest to monitor the lungs or in the neck to monitor the trachea. The monitored sound signal is identified by the microprocessor and then a corresponding pressing command is sent to the pressing device. Neck auscultation can obtain respiratory rate data and respiratory intensity data. It can also determine the presence and degree of upper airway obstruction through tracheal breath sounds, and whether the obstruction is caused by posterior displacement of the tongue or fluid obstruction. Different types of obstruction have unique auscultatory sounds. For example, when obstruction is caused by saliva secreted by the patient or gastric reflux, prominent crackles can be heard on neck auscultation. When the patient's airway obstruction is caused by posterior displacement of the tongue, a high-pitched inspiratory wheezing or complete absence of breath sounds (complete obstruction) can be heard. When the patient's airway is irritated by sputum or gastric juice and the bronchi are spasmed, a high-pitched expiratory wheezing can be heard. Respiratory rate and respiratory intensity are even easier to determine through auscultation, especially with real-time monitoring and the ability to obtain their trends. The clinical significance of different breath sounds can be trained and determined using artificial intelligence.
[0041] The vital signs monitoring module can also be a combination of an electrocardiogram monitor and an electronic stethoscope.
[0042] The edge of the contact surface between the electronic stethoscope and the patient has a double concave cap-shaped protrusion made of elastic material, so that the electronic stethoscope can be fixed to the patient's neck by creating negative pressure in the contact space; the contact surface between the electronic stethoscope and the patient is equipped with an infrared monitoring device to monitor whether the electronic stethoscope has fallen off.
[0043] This invention also provides a big data-based pressure system control method for controlling a big data-based pressure system, comprising the following steps: a. Acquisition of vital signs data: The vital signs monitoring module monitors the patient's vital signs data in real time and transmits it to the big data vital signs analysis module; the vital signs monitoring module may be an electrocardiogram monitor or an electronic stethoscope, or a combination of both, and the vital signs data may be unimodal or multimodal; b. Vital Signs Data Analysis: The big data vital signs analysis module analyzes the monitored vital signs data to determine whether the patient requires chest or abdominal compression therapy. Indications for compression therapy include: I. Electrocardiogram (ECG) Monitor Data Blood oxygen saturation is below a certain value (e.g., 90%), or Respiratory rate below a certain value (e.g., 8 breaths / min), or Breathing effort is lower than baseline by a certain percentage (e.g., 30%), or Heart rate below (e.g., 50 beats / min) or above (120 beats / min) a specific value.
[0044] II. Electronic Stethoscope Data Respiratory rate below a certain value (e.g., 8 breaths / min), or Breathing effort is less than a certain percentage (e.g., 30%) of the baseline.
[0045] If it is determined that the patient needs compression therapy, then determine the force, frequency, and duration of chest or abdominal compressions. c. Instruction generation: Generate a series of instructions from the compression parameters in step b and transmit them to the chest and abdomen compression device. d. Execution instructions: The microprocessor of the chest and abdominal compression device executes the compression instructions from the big data vital signs analysis module, and controls the drive device to drive the operation of the compression device; e. End of instruction: The press instruction ends when the operating time of the drive device reaches the duration specified by the press instruction, or when the operator performs the operation manually.
[0046] The big data vital signs analysis module is a data analysis module based on training with big data on vital signs. The training data can come solely from ECG monitor data, primarily from patients under intravenous general anesthesia or patients under other anesthesia methods, such as regional blockade (which may also result in respiratory depression). Data includes, but is not limited to: respiratory rate, respiratory strength, blood oxygen saturation, heart rate, and blood pressure; it can also come solely from stethoscope audio data, including recordings from a standard stethoscope and monitoring data from an electronic stethoscope; or it can come from both. The final output of the data analysis is: whether the patient needs chest or abdominal compression therapy; and the operating parameters of the chest and abdominal compression device. Whether compression therapy is needed and the parameters for compression therapy can be determined solely by ECG monitor data or electronic stethoscope data, or by both. The output sub-results of the ECG monitor data include: 1. Degree of hypoxia; 2. Degree of hypoxia; 3. Respiratory rate and its trend; 4. Respiratory strength (judged by the respiratory curve and its trend). The output sub-results of the electronic stethoscope data include: 1. respiratory rate and its trend; 2. respiratory strength and its trend; 3. possible causes affecting breathing. The data from the electrocardiogram monitor and electronic stethoscope are judged and labeled by professional physicians and divided into training set and test set. The training set is used by the big data vital signs analysis module for learning, while the test set is used to test the big data module.
[0047] In addition to controlling the chest and abdominal compression device through the big data vital signs analysis module, the data monitored by the electronic stethoscope can also analyze the possible causes of current respiratory distress events, such as posterior displacement of the tongue, sputum obstruction, and bronchospasm, which has positive clinical significance.
[0048] The chest and abdominal compression device provided by this invention can be fixed to a designated location on the patient before anesthesia, such as the upper abdomen below the xiphoid process or the lateral chest, using straps or other methods for fixation. The first strap 61 and the second strap 62, along with the strap rods located on both sides of the base plate 7, allow the compression device to be fixed at any position within a relatively large range on the patient. After the patient undergoes intravenous general anesthesia, the anesthesiologist can directly perform compressions on the patient via the corresponding button to stimulate respiratory recovery and reduce the risk of hypoxemia. Furthermore, through a vital sign monitoring module, such as an electrocardiogram monitor or an electronic stethoscope, or a combination of both, the patient's vital signs can be monitored in real time. When respiratory depression occurs, the corresponding compressions are automatically performed, increasing the accuracy of the compression indications and reducing the workload of the anesthesiologist.
