[0037] The present invention provides a cardiopulmonary resuscitation machine 100, which uses high-pressure gas as a power source to automatically provide accurate and efficient chest compression and mechanical ventilation support for patients with cardiac arrest and respiratory arrest. The cardiopulmonary resuscitation machine 100 is suitable for performing uninterrupted cardiopulmonary resuscitation and first aid on patients outside a hospital, inside a hospital, and during patient transportation, and can be equipped in 120 ambulances, emergency rooms, or public places.

[0038] Please refer to Figures 1 to 3In the first embodiment of the present invention, the cardiopulmonary resuscitation machine 100 includes a shell assembly 10, a control assembly 30, a pneumatic pressing assembly 50 and a breathing ventilation assembly 70, wherein the shell assembly 10 is formed with a accommodating cavity; the control assembly 30 is arranged in the accommodating cavity; the pneumatic pressing assembly 50 includes an air source, a cylinder 53 and a pressing head 55, the cylinder 53 is arranged in the accommodating cavity and communicated with the air source, the pressing head 55 is exposed from the shell assembly 10 and connected to the output end of the cylinder 53, under the control of the control assembly 30, the cylinder 53 drives the pressing head 55 to reciprocate linearly relative to the shell assembly 10; the breathing ventilation assembly 70 is arranged in the accommodating cavity and electrically connected to the control assembly 30, the breathing ventilation assembly 70 is communicated with the air source, and has a gas output interface 71 exposed from the shell assembly 10.

[0039] In this embodiment, the housing assembly 10 is used to protect the control assembly 30, the pneumatic pressing assembly 50 and the breathing and ventilation assembly 70 installed in the accommodating cavity. The structure of the housing assembly 10 can be a box, a body or a bracket with an installation cavity. The shape of the housing assembly 10 can be a cube, a rectangular parallelepiped or a cylinder, etc., which is not limited here. The pneumatic pressing assembly 50 and the breathing and ventilation assembly 70 are both electrically connected to the control assembly 30, so as to realize mechanical compression and ventilation assistance of a specific frequency under the action of electrical control.

[0040] It can be understood that the pneumatic pressing assembly 50 is a mechanical pressing action achieved under the drive of gas, and the gas here needs to be high-pressure gas. Specifically, the pneumatic pressing assembly 50 includes a gas source, a cylinder 53 and a pressing head 55. The gas source here is a gas storage tank, for example, an oxygen cylinder (high-pressure oxygen 0.35MPa~0.5MPa), etc. The cylinder 53 is connected to the gas source, and the pressing head 55 is connected to the output end of the cylinder 53, so that after the cylinder 53 obtains the gas as a driving force, it drives the pressing head 55 to achieve linear reciprocating motion. Here, the specifications of the gas storage tank can be a small oxygen cylinder, which is arranged outside the shell assembly 10 and is detachably connected to the gas supply port of the shell assembly 10 through a gas source pipe. The gas supply port is connected to the cylinder 53, so that it can be removed from the shell assembly 10 when not in use, which is convenient for storage and carrying, and is used in emergency scenarios outside the hospital. Of course, in other embodiments, the gas source may also be an air compressor or an output pipeline, for example, the cardiopulmonary resuscitation machine 100 is used in conjunction with an ambulance or an emergency room, and the output pipeline is the central gas source output pipeline of the ambulance or the emergency room. Thus, when the patient is sent to the ambulance or the emergency room, the breathing ventilation component 70 of the cardiopulmonary resuscitation machine 100 can be used to achieve effective ventilation for the patient to ensure sufficient gas source.

[0041] Here, the cylinder 53 can be a single-acting cylinder 53, that is, there is only one place where gas is introduced to drive the piston 533 to move, and it is restored to the original position through other mechanical structures; it can also be a double-acting cylinder 53, that is, the gas source is connected on both sides of the piston 533, and the gas on both sides is introduced at intervals, so as to realize the reciprocating motion of the piston 533, which is not limited here. In order to achieve comfortable and safe pressing, the material of the pressing head 55 can be silicone with moderate hardness and good biocompatibility. Of course, its material can also be metal or other, and a silicone pad can be set on it. In order to realize the air source entering the patient, the breathing ventilation component 70 is connected to the air source, and it also includes an output accessory component, which includes a breathing hose and a mask. One end of the breathing hose is connected to the gas output interface 71, and the other end is connected to the mask. The material of the mask is silicone, which can fit closely with the patient's face to ensure that the gas is input into the patient's mouth. Of course, in order to facilitate the fixing of the mask, a silicone head cover can also be included, which is set on the patient's head to ensure the stability and effectiveness of ventilation.

[0042] The cardiopulmonary resuscitation machine 100 of the technical solution of the present invention comprises a housing assembly 10, a control assembly 30 arranged on the housing assembly 10, a pneumatic pressing assembly 50 and a breathing and ventilation assembly 70. The pneumatic pressing assembly 50 comprises an air source, a cylinder 53 and a pressing head 55. Under the action of the air source, the cylinder 53 can realize linear reciprocating motion. The pressing head 55 is connected to the output end of the cylinder 53 and can realize the reciprocating pressing effect relative to the housing assembly 10. At the same time, the air source is also connected to the breathing and ventilation assembly 70 and outputs a stable output gas to achieve the ventilation effect on the patient. In this way, on the one hand, the structure can save manpower, reduce the fatigue of medical staff, reduce the ability requirements of rescuers, effectively improve the pressing and ventilation effects, and the combination of pressing and ventilation can improve the success rate of first aid; on the other hand, the pressing head 55 is driven by gas and can share the air source with the breathing and ventilation assembly 70, so as to reduce the driving components and compact structure, further reduce the specifications and size of the cardiopulmonary resuscitation machine 100, realize compactness and portability, and improve the efficiency of first aid.

[0043] Please combine Figure 4 and Figure 5 In an optional embodiment, the cylinder 53 includes a cylinder barrel 531, a piston 533, a piston rod 535 and an elastic member 537, wherein the piston rod 535 is the output end, one end of the piston rod 535 is connected to the piston 533, and the other end is connected to the pressing head 55, the elastic member 537 is sleeved on the piston rod 535, and the two ends respectively abut against the piston 533 and the wall of the cylinder barrel 531, and the end of the cylinder barrel 531 away from the pressing head 55 is connected to the air source.

[0044] In this embodiment, the cylinder 53 is a single-acting cylinder 53, that is, the cylinder 53 has only one gas input port, so that the components for controlling the gas can be reduced, and the openings of the cylinder barrel 531 can be reduced, thereby ensuring the airtightness of the cylinder 53 and achieving a better pressing and restoring effect. Specifically, the cylinder barrel 531 of the cylinder 53 is arranged along the vertical direction, that is, the movement direction of the piston 533 is the vertical direction, which is the vertical direction in which the pressing head 55 faces the ground as a reference when the cardiopulmonary resuscitation machine 100 is in use. The piston 533 is arranged in the cylinder 531, and the elastic member 537 is sleeved on the piston rod 535. The elastic member 537 can be a spring or a corrugated tube, and respectively abuts the piston 533 and the lower cylinder wall. The gas enters from the upper end to drive the piston 533 to move downward, and the piston 533 drives the piston rod 535 and then pushes the pressing head 55 to achieve downward pressing. At this time, the elastic member 537 is pressed to elastically deform. After the gas source is turned off, the piston 533 returns to the original position under the restoring force of the elastic member 537, and then drives the pressing head 55 to lift upward, and so on and so forth, to achieve a pressing effect of a certain frequency. The upper end surface of the cylinder 531 is provided with an opening connected to the gas source. The elastic member 537 is sleeved on the piston rod 535, which can maximize the use of the space in the cylinder 531 to increase the pressing stroke, and ensure the stability of the deformation direction of the elastic member 537, thereby improving the pressing performance. The piston rod 535 and the piston 533 are separate structures, and the piston rod 535 and the pressing head 55 are also separate structures, thereby facilitating the processing and assembly of each component.

[0045] Of course, in other embodiments, the elastic member 537 can also be arranged on the top of the piston 533, and gas can be introduced into the lower end of the cylinder 531 to lift the pressing head 55 upward by gas drive, and press the pressing head 55 downward by the restoring force of the elastic member 537.

[0046] In an optional embodiment, the cylinder 53 further includes a limiter 539 , and the limiter 539 is disposed at one end of the cylinder barrel 531 close to the pressing head 55 to limit the movement stroke of the piston 533 .

[0047] Here, in order to limit the pressing stroke of the piston 533, a limiter 539 is provided at the lower part of the cylinder 531, and the limiter 539 is arranged at the periphery of the elastic member 537 and is used to limit the movement stroke of the piston 533. Optionally, the limiter 539 can be a cylindrical tube, arranged around the periphery of the elastic member 537, which can increase the area of ​​contact with the piston 533, thereby improving the support stability and ensuring the control accuracy of the pressing depth. It can be understood that the height of the limiter 539 is higher than the ultimate compression height of the elastic member 537, so that the limiter 539 bears the support and limiting effect, protects the elastic member 537, and improves the performance of the elastic member 537. Of course, in other embodiments, the limiter 539 can also be set to be only a block structure, and two or more spaced and evenly distributed on the periphery of the elastic member 537 are set.

[0048] Please continue to refer to Figure 2 In an optional embodiment, the pneumatic pressing assembly 50 further includes a pressing regulating air circuit block 57 and a first regulating valve 59, wherein the first regulating valve 59 is disposed on the pressing regulating air circuit block 57, wherein one end of the pressing regulating air circuit block 57 is connected to the air source, and the other end is connected to one end of the cylinder 53;

[0049] And / or, the breathing ventilation component 70 includes a ventilation regulating air circuit block 73 and a second regulating valve 75, the second regulating valve 75 is arranged on the ventilation regulating air circuit block 73, one end of the ventilation regulating air circuit block 73 is connected to the air source, and the other end is connected to the gas output interface 71.

[0050] In this embodiment, the pneumatic pressing assembly 50 also includes a pressing regulating gas circuit block 57 and a first regulating valve 59. The pressing regulating gas circuit block 57 is a collection of various pipelines, which can provide pipeline connectors with different directions. The first regulating valve 59 is installed on the pressing regulating gas circuit block 57, which can be located between the gas source and the pressing regulating gas circuit block 57, or between the pressing regulating gas circuit block 57 and the cylinder 53, so that the pressing depth can be adjusted under the control of the control assembly 30 to meet the pressing requirements. Of course, in order to ensure that the gas output by the gas source can stably and effectively provide driving force, the pneumatic pressing assembly 50 also includes a pressure reducing valve, which is used in conjunction with the first regulating valve 59 to provide a suitable gas pressure to the cylinder 53, and cooperate with the gas control valve to adjust the output frequency of the cylinder 53, thereby achieving the purpose of controlling the pressing frequency.

[0051] At the same time, in order to control the breathing ventilation component 70, it includes a ventilation regulating gas circuit block 73 and a second regulating valve 75. The ventilation regulating gas circuit block 73 is also a collection of various gas transmission pipelines, and is provided with multiple pipeline joints, which can be used to communicate with various valve bodies and gas output interfaces 71. The second regulating valve 75 is arranged on the ventilation regulating gas circuit block 73, and can adjust the tidal volume of the gas on the gas circuit. The tidal volume refers to the amount of inhaled gas, that is, the amount of gas input to the patient, so as to achieve the purpose of cardiopulmonary resuscitation. Of course, according to needs, a pressure reducing valve is installed on the ventilation regulating gas circuit block 73 to convert the high-pressure gas of the gas source into low-pressure gas, and ensure that it is within the normal acceptance range of the patient, so as to be suitable for the patient to inhale, so as to achieve the ventilation effect on the patient.

[0052] Please continue to refer to Figure 2 In an optional embodiment, the control component 30 includes an electric control board 31 and two solenoid valves 33, the two solenoid valves 33 are electrically connected to the electric control board 31, one solenoid valve 33 is connected between the air source and the pressing regulating air circuit block 57, and the other solenoid valve 33 is connected between the air source and the ventilation regulating air circuit block 73.

[0053] In this embodiment, in order to increase the control mode of the cardiopulmonary resuscitation machine 100, the control component 30 is provided to include an electric control board 31 and two solenoid valves 33. The electric control board 31 is provided with a control circuit and is electrically connected to the two solenoid valves 33 respectively. One solenoid valve 33 is installed between the gas source and the compression regulating gas circuit block 57 to control the conduction and closing of the compression regulating gas circuit block 57. The other solenoid valve 33 is connected between the gas source and the ventilation regulating gas circuit block 73 to control the conduction and closing of the gas circuit. In this way, a gas source main circuit can be divided into two branches to input the two gas circuits. The cardiopulmonary resuscitation machine 100 can have three modes: 1. Continuous compression mode. At this time, the solenoid valve 33 connected to the ventilation regulating gas circuit block 73 is closed, and the solenoid valve 33 connected to the compression regulating gas circuit block 57 is turned on, so that the cylinder 53 can continuously press the patient's chest for emergency treatment. At this time, the electric control board 31 can also be manually triggered to adjust the first regulating valve 59 to control the compression depth. Second, continuous breathing mode, at this time, the solenoid valve 33 connected to the ventilation regulating air circuit block 73 is turned on, and the solenoid valve 33 connected to the pressing regulating air circuit block 57 is closed, so that the gas enters the ventilation regulating air circuit block 73 to realize ventilation of the patient, so that the patient can realize autonomous breathing. At this time, the second regulating valve 75 can be manually adjusted according to the needs of the patient to control the tidal volume to improve the efficiency of first aid. Third, the compression and breathing are carried out in a proportional mode, where the ratio of compression to breathing can be 30:2 or 15:2, and the compression air circuit and the ventilation air circuit are operated according to the frequency ratio of 30:2 or 15:2 by adjusting the opening and closing of the two regulating valves. The ratio of compression to breathing can be 30:2, then the cardiopulmonary resuscitation machine 100 will perform 30 chest compressions, then pause for 4 seconds, during the pause, perform 2 ventilations, and then repeat the compression 30 times, and so on. In this way, the rescuer can select different modes according to the patient's situation, thereby improving the rescue efficiency and success rate.

[0054] In an optional embodiment, the control component 30 further includes a display screen 35 , the housing component 10 is provided with a first mounting opening 1111 , the display screen 35 is mounted at the first mounting opening 1111 , and is electrically connected to the electric control board 31 .

[0055] It is understandable that in order to monitor the working parameters of the cardiopulmonary resuscitation machine 100 at all times, the control component 30 also includes a display screen 35, so that the working parameters can be compared and adjusted according to actual conditions. Specifically, because the pressing head 55 is arranged on the lower surface of the shell component 10 for pressing movement, the display screen 35 is arranged on the surface of the shell component 10 away from the pressing head 55, that is, the upper surface. A first mounting port 1111 is provided on the upper surface of the shell component 10, and the display screen 35 is installed at the first mounting port 1111 and exposed at the first mounting port 1111, so as to facilitate the rescuer to observe.

[0056] Optionally, the control assembly 30 further includes a control key 39, which is electrically connected to the electric control board 31. After the cardiopulmonary resuscitation machine 100 is turned on, the display screen 35 can display the power level, time, and the system setting options of the cardiopulmonary resuscitation machine 100 itself according to the settings of the electric control board 31, so as to facilitate the maintenance of the device and the transmission and storage of data. In the pneumatic compression or breathing mode, the display screen 35 can also display parameters such as the compression mode, compression depth or breathing rate, and the display method can be a numerical value or a combination of a numerical value and a waveform diagram, which is not limited here. The display screen 35 can be a touch screen, and the control key 39 is a button displayed on the screen, and the parameter adjustment or system setting is performed directly by touching the screen. Of course, the display screen 35 can also be a non-touch screen, and the control key 39 is set on the periphery of the display screen 35. The control key 39 can be a membrane button to realize the functions of turning pages up and down, confirming or returning, so as to realize the system setting of the device itself. At the same time, a membrane button is provided to select the operating mode, start and pause, or connect the gas source, and the control button can also be a knob, and a compression depth knob and a ventilation volume knob are provided to adjust parameters such as compression depth and ventilation volume, so as to more accurately control the working parameters of the cardiopulmonary resuscitation machine 100 and ensure its performance.

[0057] In addition, in an optional embodiment, the control component 30 includes a Bluetooth module or a wireless module. In this way, the rescuer can connect the mobile device to the cardiopulmonary resuscitation machine 100 via the Bluetooth module, so as to directly control various parameters of its operation, such as compression frequency, etc., through the mobile device.

[0058] Please combine Figure 2 and Figure 6 In an optional embodiment, the control component 30 also includes a monitoring light 37, and the monitoring light 37 is installed in the second installation port 1113 opened in the shell component 10 and is electrically connected to the electric control board 31.

The monitoring light 37 includes a plurality of LED lamp beads, which are arranged in an array, and the changes in the compression depth are displayed in real time by the on and off of the light. It is simple and direct, and it is convenient for the operator to adjust according to needs. Specifically, a magnet and a Hall sensor are provided on the compression head 55. The Hall sensor collects the magnetic field changes brought by the magnet to monitor the compression depth, so that the collected data is transmitted to the control board, and the control board displays it through the monitoring light 37. Here, the compression depth range of the cardiopulmonary resuscitation machine 100 can be 1 to 6 cm, for example, 1 cm, 2 cm, 3 cm, 5 cm, 6 cm, etc.

[0060] It can be understood that the housing assembly 10 includes a chassis 13 and a shell 11 connected to the chassis 13 , and the shell 11 and the chassis 13 are enclosed to form the accommodating cavity.

The two enclose a mounting cavity. The chassis 13 is provided with an escape hole for the movement of the pressing head 55. The connection between the chassis 13 and the shell 11 is a detachable connection, for example, a threaded connection, so that it is convenient to install the pneumatic pressing assembly 50 and the breathing ventilation assembly 70 on the chassis 13, and then install the display screen 35 and the electric control board 31 on the shell 11, and finally connect the shell 11 with the chassis 13, which is convenient for assembly and disassembly and convenient for later maintenance. Of course, in order to facilitate the carrying of the cardiopulmonary resuscitation machine 100, the shell 11 includes a main body and a handheld part, and the handheld part is connected to the periphery of the main body for handholding. Optionally, there are two handheld parts, and the two handheld parts are respectively arranged on both sides of the upper end of the main body, that is, on both sides of the display screen 35, so that when the cardiopulmonary resuscitation machine 100 is held by hand, operations such as turning on or setting can be performed at the same time, thereby improving convenience.
