Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a cardiopulmonary resuscitation device and a control method thereof. Background Art

[0002] Cardiopulmonary resuscitation (CPR) is a key measure to rescue patients with cardiac arrest. Traditional CPR methods use chest compressions for artificial circulation, but this method has certain risks for patients with chest fractures. Due to the fracture of the ribs or sternum, the integrity of the thorax is destroyed. Traditional chest compressions are prone to cause further damage, such as pneumothorax, hemothorax, etc., and may even cause the broken ends of the fractures to pierce the internal organs. In addition, due to the collapse of the chest cavity, it is difficult for traditional CPR methods to effectively perform chest compressions, resulting in poor resuscitation results.

[0003] Most existing cardiopulmonary resuscitation devices are not specially designed for patients with thoracic fractures, and their compression depth and strength are fixed and cannot be adjusted according to the specific conditions of the patients. This can easily cause secondary injuries to patients with thoracic fractures and reduce the success rate of CPR.

[0004] Therefore, there is an urgent need for a cardiopulmonary resuscitation device that can adapt to the special needs of patients with thoracic fractures, which can effectively perform chest compressions and improve the success rate of CPR while avoiding secondary injuries. Summary of the invention

[0005] In order to overcome the problems that the existing cardiopulmonary resuscitation devices in the related art have fixed pressing depth and force, which cannot be adjusted according to the specific conditions of the patients, which easily causes secondary injuries, and the chest collapse leads to poor pressing effects, thereby reducing the success rate of cardiopulmonary resuscitation, one of the purposes of the present invention is to provide a cardiopulmonary resuscitation device, which integrates a reciprocating drive module, an adsorption module with adjustable negative pressure, a chest collapse detection module and a control module. The control module dynamically adjusts the pressing depth and frequency of the reciprocating drive module and the adsorption force of the adsorption module according to the real-time data provided by the chest collapse detection module, so as to overcome the problems in the prior art that secondary injuries are easily caused and the pressing effect is poor when performing cardiopulmonary resuscitation on patients with chest fractures, thereby improving the success rate of cardiopulmonary resuscitation.

[0006] A cardiopulmonary resuscitation device, comprising:

[0007] A reciprocating drive module comprises a fixed frame, a drive assembly and a movable part, wherein the drive assembly is fixed on the fixed frame, and the drive assembly drives the movable part to perform reciprocating motion;

[0008] An adsorption module, comprising an active suction cup, wherein the active suction cup is arranged on the movable part;

[0009] A chest collapse detection module, comprising a force sensor and a distance sensor, wherein the force sensor is arranged on the movable part, and the distance sensor is arranged on the reciprocating drive module;

[0010] A control module, the reciprocating drive module, the adsorption module and the chest collapse detection module are electrically connected to the control module.

[0011] Furthermore, the chest collapse detection module monitors the pressing force and pressing stroke through a force sensor and a distance sensor. When the same force is used on the chest and a larger stroke is achieved, or a smaller force is collected with the same stroke, it is judged as chest collapse.

[0012] Furthermore, the adsorption module also includes a negative pressure pump and a control valve, the active suction cup is connected to the negative pressure pump, the control valve is connected to the negative pressure pump, the negative pressure pump is used to generate negative pressure, and the control valve is used to adjust the size of the negative pressure.

[0013] The negative pressure pump and control valve make the adsorption force of the active suction cup controllable and adjustable. The control valve can accurately adjust the negative pressure generated by the negative pressure pump, thereby controlling the adsorption force of the active suction cup. This allows the device to adapt to the chest and skin conditions of different patients and provide appropriate adsorption force, which not only ensures the effectiveness of adsorption, but also avoids skin damage caused by excessive adsorption force.

[0014] Furthermore, the force sensor includes a pressure sensor and a tension sensor. The pressure sensor includes but is not limited to a piezoresistive sensor, a capacitive sensor, a piezoelectric sensor, a magnetoelectric sensor, a strain pressure sensor, an optical fiber pressure sensor, a spoke sensor, etc. Its main function is not only to measure whether the pressing force is sufficient, but also to work with the negative pressure pump and the tension sensor. When the pressure sensor senses the presence of pressure, the negative pressure pump starts working and generates negative pressure to adsorb the patient's chest. The tension sensor measures the adsorption force and adjusts the working intensity of the negative pressure pump in real time according to the size of the adsorption force.

[0015] Furthermore, the negative pressure pump includes but is not limited to an electric one-way suction pump, an electric two-way suction pump, and a spare manual suction pump. When an electric one-way suction pump is used, it is used to pump air during operation, and after cardiopulmonary resuscitation is completed, the pressure can be relieved by gently moving the edge of the active suction cup; when an electric two-way suction pump is used, it is used to pump air during operation, and after cardiopulmonary resuscitation is completed, the pressure can be relieved by exhausting the electric two-way suction pump. In addition, when the negative pressure is insufficient due to some reasons, a manual suction pump can be used to increase the pressure to obtain the appropriate pressure.

[0016] Furthermore, the control module can monitor the chest rebound in real time through the feedback data from the tension sensor. When the ribs are broken and the chest has difficulty rebounding, the signal is transmitted to the negative pressure pump to increase the suction volume, form a larger negative pressure, and allow chest compression to proceed smoothly.

[0017] Furthermore, it also includes a ventilation module, which is connected to the control module.

[0018] The ventilation module enables the device to provide breathing support to the patient while performing chest compressions, further improving the success rate of cardiopulmonary resuscitation.

[0019] Furthermore, the ventilation module includes a ventilation bag, an air inlet and an airway, the ventilation bag is arranged between the fixed frame and the movable part, one end of the ventilation bag is connected to the fixed frame, and the other end is connected to the movable part, and the ventilation bag is respectively connected to the air inlet and the patient through the airway.

[0020] The coordination of the ventilation bag, air inlet, airway and movable parts can achieve positive pressure ventilation, effectively deliver air to the patient's lungs and improve the patient's oxygenation status. When the movable parts move, the ventilation bag is stretched to inhale through the air inlet, and the ventilation bag is compressed to ventilate the patient through the airway, achieving a 1:1 compression-to-breathing ratio, which can more accurately control the ventilation volume and ventilation pressure, and improve the efficiency and safety of ventilation.

[0021] Furthermore, the structure of the ventilation bag includes but is not limited to an accordion bellows shape, an artificial lung shape, an ellipsoidal balloon shape, etc. It is compressible both laterally and longitudinally, and its materials include but are not limited to natural rubber, silicone rubber, BOPP, HDPE, PP and other non-toxic and harmless materials.

[0022] Furthermore, the ventilation module also includes a one-way valve, a pressure regulating valve, and a throttle valve. The high-frequency ventilation tidal volume is 1-6 ml / kg. The ventilation pressure is controlled by the pressure regulating valve. The ventilation pressure is about 3-30 cmH2O. The one-way valve, the pressure regulating valve, and the throttle valve use a 2mm to 10mm pipe interface at the connection with the airway.

[0023] Furthermore, the ventilation module also includes an airbag width adjuster, which is used to adjust the width of the ventilation airbag. The airbag width adjuster includes but is not limited to a three-jaw chuck, a four-jaw chuck, a universal joint chuck, a wedge clamping mechanism, a spiral clamping mechanism, a pneumatic clamping mechanism, an eccentric clamping mechanism, a hinge clamping mechanism, etc. The airbag width adjuster can change the cross-section of the ventilation airbag to adjust the amount of ventilation.

[0024] Furthermore, in addition to the linkage between the ventilation airbag and the movable part, the ventilation module may also include a pressing component, the pressing component is used to press the ventilation airbag, and the pressing component is electrically connected to the control component.

[0025] Furthermore, the ventilation module can also be composed of an air inlet, an air filter, a solenoid valve, a safety valve, a pressure regulating valve, a throttle valve and a cylinder. The solenoid valve, the safety valve, the pressure regulating valve, the throttle valve and the cylinder are connected to the control module and controlled by the control module.

[0026] Furthermore, it also includes an abdomen lifting module, and the abdomen lifting module is electrically connected to the control module;

[0027] The abdomen lifting module includes a fixed chassis, a height adjustment column and a lifting component. The fixed chassis is used to pad under the patient. The height adjustment column is fixed on the fixed chassis. The lifting component includes a lifting driver and a lifting plate. The lifting driver drives the lifting plate to move closer to or away from the fixed chassis. The lifting plate is fixed on the height adjustment column.

[0028] The abdominal lifting module can be used in conjunction with chest compressions to lift the abdomen, simulate diaphragmatic movement, assist breathing, and improve ventilation. The height-adjustable lifting board can adapt to the body shape of different patients, the fixed chassis provides stable support, and the lifting driver can control the timing, frequency, and amplitude of the lifting, thereby achieving a more accurate, effective, and comfortable abdominal lifting.

[0029] Furthermore, the abdominal lifting module also includes a pressing head and a lifting driver, and the initial position of the lifting plate is adjusted by a height adjustment column to cooperate with the lifting driver to work. The lifting component has two working modes, one is a fixed position mode, and the other is a chest compression mode. The specific method of coordinating with the chest compression mode is that when the chest is pressed, the lifting plate rises appropriately; when the chest rebounds, the lifting panel drops appropriately to enhance the activity of the diaphragm to achieve a better cardiopulmonary resuscitation effect.

[0030] Furthermore, the pressing head can be made of silicone material, including but not limited to butyl rubber, polyurethane elastomer, chloroprene rubber, polysulfide rubber, nitrile rubber and other materials. Its main function is to reduce local stress on the abdomen and prevent damage to the patient when the abdomen is lifted and compressed.

[0031] Furthermore, the pressing method of the pressing head includes the forward and reverse rotation of the motor to drive the screw to work, and also includes the pneumatic control of the opening and closing of the solenoid valve to control the pressing method.

[0032] Furthermore, a monitoring module is also included, the monitoring module is electrically connected to the control module, the monitoring module is used to monitor the patient's vital signs and transmit the monitoring data to the control module, and the monitoring module includes:

[0033] Blood oxygen sensor, used to monitor blood oxygen saturation;

[0034] Blood pressure sensor, used to monitor blood pressure;

[0035] Respiration sensor to monitor respiratory rate and tidal volume;

[0036] The monitoring module can monitor the patient's key vital signs such as blood oxygen saturation, blood pressure and respiratory rate in real time, and transmit the data to the control module. The control module can adjust the compression depth, frequency, ventilation volume, etc. according to the monitoring data, thereby achieving more personalized CPR treatment and improving the effectiveness and safety of CPR.

[0037] Furthermore, a display screen may be included, and the monitoring data may be displayed on the display screen of the device in real time, which is convenient for the operator to observe. The monitoring data may also be stored in the memory of the device, which is convenient for subsequent analysis and evaluation.

[0038] Furthermore, it also includes a defibrillator module, which is electrically connected to the control module and includes:

[0039] A pair of defibrillation electrodes for connection to the patient;

[0040] An energy storage and release unit for storing and releasing defibrillation energy;

[0041] The defibrillator module is electrically connected to the control module, and the control module controls the operation of the defibrillator module according to the monitoring data.

[0042] The integrated defibrillation module enables the device to perform defibrillation immediately when needed without changing the device, thereby saving precious rescue time and improving the patient's survival rate. The control module can automatically determine whether defibrillation is needed based on the monitoring data, and control the energy release unit to release defibrillation energy, thereby achieving automated defibrillation and improving the efficiency and safety of defibrillation.

[0043] Furthermore, the control module controls the operation of the defibrillator module according to the monitoring data. When the patient is in a very bad condition, such as cardiac arrest, rapid drop in blood pressure, etc., the defibrillator module automatically performs the defibrillation operation.

[0044] Furthermore, the driving assembly includes a motor and a nut, the movable part includes a lead screw, the motor is drivingly connected to the nut, the motor drives the nut to rotate, and the nut is threadably matched with the lead screw.

[0045] The motor-driven lead screw nut mechanism can accurately control the reciprocating motion of the moving parts, achieve precise control of compression depth, frequency and waveform, and improve the quality of CPR. The motor drive also makes the device more automated and reduces the burden on the operator.

[0046] Further, the active suction cup is selected from a first suction cup, a second suction cup and a third suction cup;

[0047] The first suction cup is a circular suction cup;

[0048] The second suction cup is provided with at least two inner recesses for avoiding the breast;

[0049] A decompression component is arranged in the third suction cup.

[0050] Due to the large difference between male and female chests, if the same round suction cup is used, there will be some gaps on the chest of women when using the suction cup, resulting in insufficient negative pressure or even failure to suck. Three different types of suction cups are provided to better adapt to patients of different genders and ages. The round suction cup is suitable for standard body shapes, the suction cup with inner concave is suitable for female patients, and the decompression suction cup is suitable for the elderly or patients with fragile chests, thereby improving the safety of CPR and avoiding secondary injuries.

[0051] Furthermore, the third suction cup adds a shock-absorbing device inside the conventional suction cup, and the shock-absorbing device includes but is not limited to a small suction cup, a spring decompression and other structures to reduce the risk of rib fractures and injuries after fractures.

[0052] A second object of the present invention is to provide a control method for a cardiopulmonary resuscitation device, which is applied to the cardiopulmonary resuscitation device as described above, and comprises the following steps:

[0053] Suction the patient's chest through the suction module;

[0054] Cardiopulmonary compression is performed through a reciprocating drive module;

[0055] Detecting the degree of chest collapse by the chest collapse detection module;

[0056] According to the degree of chest collapse, the working parameters of the driving component and the negative pressure adsorption force of the active suction cup are adjusted.

[0057] The beneficial effects of the present invention are:

[0058] The present invention provides a cardiopulmonary resuscitation device, which includes a reciprocating drive module, an adsorption module, a chest collapse detection module and a control module. The driving component drives the movable part to perform reciprocating motion to simulate the pressing action of artificial cardiopulmonary resuscitation. At the same time, the active suction cup adsorbs the patient's chest to provide support, and cooperates with the force sensor and the distance sensor to detect the degree of chest collapse in real time. The control module adjusts the working state of the driving component and the adsorption module according to the detection results, so as to achieve adaptability to different chest conditions, especially for patients with chest fractures, to avoid secondary injuries caused by excessive compression, and improve the effectiveness and safety of cardiopulmonary resuscitation. The control module can adjust the compression and adsorption parameters in real time according to the degree of chest collapse, so as to avoid further damage to the collapsed chest.

[0120] Example 2

[0121] like Figures 4 to 7 As shown, this embodiment provides a cardiopulmonary resuscitation device, which is used in home first aid, uses a motor to drive a lead screw nut mechanism for pressing, and uses a small oxygen cylinder to supply gas. The cardiopulmonary resuscitation device includes:

[0122] 1. Ventilation module (such as Figure 5 shown):

[0128] Throttle valve 506: used to control ventilation flow and adjust ventilation rate as needed. The junction between throttle valve 506 and airway 503 adopts a 5mm pipe interface.

[0129] 2. Reciprocating drive module 100:

When the lead screw moves downward, the chest cavity is pressed, and the ventilation bag 501 is stretched and inflated; when the lead screw moves upward, the chest cavity is stretched, and the ventilation bag 501 is compressed, and gas is pumped into the patient's body. Using the high-frequency jet method, oxygen and other gases are pumped into the lungs, which has a better oxygen supply than the traditional compression ventilation ratio of 30:2.

[0139] Control valve: controls the negative pressure of the negative pressure pump and is provided with a safety valve 510 to prevent excessive negative pressure and avoid damage to the patient's skin.

[0140] 4. Chest collapse detection module:

[0141] Force sensor: A strain sensor is used and is installed on the pressing head 633 to measure the pressing force.

[0142] Distance sensor: An ultrasonic distance sensor is used and installed on a fixed frame to measure the distance between the pressing head 633 and the chest.

[0143] When the ribs are intact, the human chest can rebound normally, and the active suction cup 210 can meet the needs of chest compression with a low suction force; when the ribs are fractured over a large area, the chest collapses and cannot rebound normally, the negative pressure pump works, the negative pressure is enhanced, and the chest rebounds, which can minimize the secondary damage caused by chest compression.

[0144] 5. Control module 400:

[0145] The control module 400 is implemented by a single chip microcomputer and is responsible for coordinating the work of each module.

[0146] The control module 400 receives signals from the chest collapse detection module, the monitoring module and the abdomen lifting module 600, and controls the working states of the reciprocating drive module 100, the adsorption module 200, the ventilation module and the defibrillation module according to these signals.

[0147] The control module 400 controls the operation of the defibrillation module according to the monitoring data. When the patient is in a very bad condition, such as cardiac arrest, rapid drop in blood pressure, etc., the defibrillation operation is automatically performed.

[0148] 6. Monitoring module (such as Figure 7 shown):

[0149] Blood oxygen sensor 710: used to monitor blood oxygen saturation.

[0150] Blood pressure sensor 720: used to monitor blood pressure.

[0151] Respiratory sensor 730: used to monitor respiratory rate and tidal volume. In this embodiment, it is an end-tidal carbon dioxide sensor.

[0152] 7. Defibrillator module (such as Figure 7 shown):

[0153] A pair of defibrillation electrodes 810: used for connection with a patient.

[0154] Energy storage and release unit: used to store and release defibrillation energy.

[0155] During the process of cardiopulmonary resuscitation, it is necessary to monitor the patient's vital signs in real time to perform different operations. Ordinary people lack sufficient medical knowledge, so in this embodiment, professional operations are built into the device in advance. By monitoring the end-of-tidal carbon dioxide, blood pressure, and blood oxygen, when the patient's vital signs are poor, automatic defibrillation is performed without stopping compression and ventilation. At the same time, because the chest collapse can be detected, the compression force can be reduced in this embodiment when the chest collapses to avoid unnecessary damage to the patient.

[0156] 8. Abdominal lifting module 600:

[0157] Fixed chassis 610: used to cushion under the patient, with anti-slip material on the bottom to ensure stability.

[0158] Height adjustment column 620: fixed on the fixed base 610, the height is adjusted by a handle or a motor to adapt to the body shapes of different patients.

[0159] The lifting assembly 630 includes a lifting driver 631, a lifting plate 632 and a pressing head 633. The lifting driver 631 is driven by a motor and can control the movement speed and amplitude of the lifting plate 632.

[0160] Lifting plate surface 632: Made of soft and wear-resistant material, fixed on the height adjustment column 620, the position can be adjusted as needed.

[0161] Pressing head 633: located on the lifting plate surface 632, and made of soft silicone material to avoid causing damage to the patient's abdomen.

[0162] Lifting driver 631: connected to the control module 400, controls the movement of the lifting plate 632, and has two modes: fixed position mode and chest compression mode.

[0163] In order to achieve better cardiopulmonary resuscitation effect at home, an abdominal lifting device can be installed. If the operator does not understand the principle of abdominal lifting, he only needs to adjust the lifting device to a suitable height and lightly touch the patient's abdomen.

[0164] Working principle:

[0165] Adsorption: Select a suitable active suction cup 210 according to the specific condition of the patient, install the active suction cup 210 on the movable part 120, place the active suction cup 210 on the patient's chest, and use the adsorption module 200 to adsorb the active suction cup 210 on the patient's chest.

[0166] Compression: Start the device, control the reciprocating drive module 100 through the control module 400, and adjust the compression depth, frequency and suction force according to the detected degree of chest collapse.

[0167] Ventilation: Based on the monitored blood oxygen saturation and respiratory rate, the control module 400 adjusts the ventilation parameters to provide appropriate respiratory support for the patient.

[0168] Defibrillation: When the monitoring module detects that the patient has arrhythmia or cardiac arrest, the control module 400 automatically starts the defibrillation module to perform defibrillation.

[0169] Abdominal lifting: Start the abdominal lifting module 600 as needed, and control the movement of the lifting plate 632 through the control module 400 to simulate diaphragm movement and assist breathing.

[0170] The cardiopulmonary resuscitation device provided in this embodiment is specially designed for home first aid. It is driven by a motor and supplied by a small oxygen cylinder, which is more convenient and easier to use. It integrates a monitoring module, a defibrillator module and an abdominal lifting module 600, can be intelligently controlled according to the patient's condition, and can adapt to patients of different genders and ages through different suction cups. It pays more attention to portability, safety and adaptability to different patients, providing reliable protection for home first aid.
