Description

Technical Field

[0001] The present application relates to the field of cardiopulmonary resuscitation equipment, and in particular to a multifunctional cardiopulmonary resuscitation machine. Background Art

[0002] Cardiopulmonary resuscitation, abbreviated as CPR, is a life-saving technique for cardiac and respiratory arrest. It is designed to restore the patient's spontaneous breathing and circulation. Cardiac arrest refers to the sudden cessation of the heart's beating due to various reasons in unexpected circumstances and time, which leads to the sudden cessation of effective cardiac pump function and effective circulation, causing severe ischemia, hypoxia and metabolic disorders of tissue cells throughout the body. If not rescued in time, the person may lose his life immediately. Cardiac arrest is different from any terminal cardiac arrest of chronic diseases. If correct and effective resuscitation measures are taken in time, the person in distress may be saved and recover.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: once cardiac arrest occurs, if no immediate and timely rescue and resuscitation is provided, irreversible damage will be caused to the patient's brain and other important organs and tissues of the persons in distress after 4 to 6 minutes. Therefore, cardiopulmonary resuscitation after cardiac arrest must be performed immediately on the spot to win the most precious time for further rescue and even saving the lives of the patients with cardiac arrest; at present, there is no cardiopulmonary resuscitation robot in China, and the existing cardiopulmonary resuscitation devices only have simple pressing or compression ventilation functions, and do not use monitoring data to form a closed-loop feedback pressing. The quality of cardiopulmonary resuscitation is not high, and the success rate of treatment is almost the same as that of manual compression treatment. For the treatment of cardiac arrest patients and critically ill patients at the scene of an emergency, cardiopulmonary resuscitation, monitoring, defibrillation, ventilation and other means are required. Therefore, rescuers need to carry multiple equipment to the scene. However, during the on-site rescue process, the number of rescue equipment carried by rescuers is limited, so there is room for improvement in efficient on-site rescue. Summary of the invention

[0004] In order to simplify the operation complexity of medical personnel during cardiopulmonary resuscitation and achieve high efficiency of cardiopulmonary resuscitation, the present application provides a multifunctional cardiopulmonary resuscitation machine device.

[0005] The present application provides a multifunctional cardiopulmonary resuscitation machine device adopts the following technical solution:

[0006] A multifunctional cardiopulmonary resuscitation machine device comprises a first aid box and a pressing device, a ventilation device, a monitoring device, a defibrillator and a control device installed on the first aid box, wherein the first aid box is integrally injection molded, and an arc-shaped pillow opening for a patient's head to rest is concavely provided on the upper end surface of the first aid box, the first aid box is covered with a protective pad, and a waist belt is pulled between the two side edges of the inner side of the protective pad, and the pressing device and the defibrillator are integrated and sleeved on the waist belt; the ventilation device comprises an oxygen pump, an oxygen mask and an air supply pipe integrated in the first aid box, and the output port of the oxygen pump passes through the first aid box and is connected to the oxygen mask; the monitoring device comprises two groups of patch-type electrical signal sensors and connected signal lines, and each group of the sensors is electrically connected to the first aid box through the signal line; the control device comprises a panel installed on one side of the first aid box, and the panel displays physiological parameters such as electrocardiogram, blood oxygen, pulse, body temperature and the like in real time; and a battery for power supply is integrated inside the first aid box.

[0007] By adopting the above technical scheme, the technical scheme of the present application has developed a portable multifunctional cardiopulmonary resuscitation machine device that can be used for on-site rescue. The one-piece injection-molded first aid box serves as the main body of the device, and the battery can power each component. The device effectively integrates chest compression, mechanical ventilation, physiological monitoring, and external defibrillation. The overall structure adopts a folding structure, and the protective pad can be wrapped around the outside of the first aid box. After folding, it becomes a backpack, which is convenient for rescue personnel to rush to the scene for rescue; when rescuing on the scene, the person in distress lies flat on the protective pad, the oxygen pump is started and the oxygen mask is covered on the mouth of the person in distress, and a certain first aid sequence is followed. At this time, each group of sensors is pasted on the body of the person in distress, and the relevant parameters are set on the panel in the control device. The multifunctional cardiopulmonary resuscitation machine device can be used for on-site rescue. The full process data of pulmonary resuscitation equipment in treating the wounded (compression time, frequency, depth, interval events, downtime, startup time, start time, end time, mechanical ventilation tidal volume, blowing time, blowing volume, monitored vital signs data, abnormal data, defibrillation time, defibrillation energy, etc.) can be stored locally and uploaded to the rear command system or hospital database at the same time to form an integrated life comprehensive treatment platform system; at the same time, all modules of chest compression, mechanical ventilation, physiological monitoring, and external defibrillation are independent of each other and systematically connected, and can be designed and flexibly combined according to the actual needs of on-site rescue, which is convenient for rapid rescue, conducive to timely and safe rescue of the wounded, and reduces the mortality and disability rates, thereby simplifying the operational complexity of medical staff during cardiopulmonary resuscitation and achieving high efficiency of cardiopulmonary resuscitation.

[0008] Preferably, a neck pillow sleeve with a bearing structure is rotatably installed inside the arc-shaped pillow opening, and an anti-slip pattern is integrally formed on the arc-shaped surface of the neck pillow sleeve on the side facing away from the first aid box body. The first aid box body has a hole on the end surface on the side away from the protective pad and is fixed with a spring pin, and the neck pillow sleeve has a hole on the annular surface on the side close to the spring pin and is plugged into and cooperated with the spring pin.

[0009] By adopting the above technical solution, a neck pillow sliding sleeve is designed at the arc-shaped pillow opening. When the rescue personnel find that there are debris in the mouth of the person in distress that needs to be cleaned, the rescue personnel will pull out the spring pin. At this time, the neck pillow sliding sleeve located inside the arc-shaped pillow opening is in a free state, and the head of the person in distress falls on the neck pillow sliding sleeve. The rescue personnel rotate the neck of the person in distress, and the head of the person in distress keeps rotating. The above process improves the convenience of clearing foreign objects from the mouth of the person in distress and reduces the harm to the person in distress during the process of position adjustment.

[0010] Preferably, a plurality of groups of sponge pads are sewn and formed on the surface of the protective pad and are distributed in parallel along the length direction, and the upper end surface of the sponge pad is coplanar with the lowest point of the inner circumference of the neck pillow sliding sleeve.

[0011] By adopting the above technical scheme, each group of sponge pads on the surface of the protective pad has a buffering and protective function, and the upper end surface of the sponge pad is kept level with the lowest point of the inner circumference of the neck pillow sliding sleeve. When the person in distress lies flat on the protective pad, the head and back of the person in distress are ensured to be on a basically horizontal plane. The above setting realizes the pillow-free balance, ensures that the airway of the person in distress is unobstructed after lying flat, facilitates the delivery and exhaust of oxygen, and meets the requirements of cardiopulmonary resuscitation operations.

[0012] Preferably, a groove matching the shape of the panel is recessed on one side of the first aid box body, a positioning block is opened and hingedly installed above the groove, and an end face of the positioning block away from the hinge axis is rotatably connected to the panel.

[0013] By adopting the above technical solution, the positioning block is hingedly connected to the position above the slot, and the positioning block is rotatably connected on the end face on the side away from the hinge axis. The above setting realizes the up and down flipping and rotation of the panel, so that the panel can be stored inside the slot in the daily storage state, and during use, it can be smoothly rotated to the upper end face of the first aid box body, which is convenient for rescue personnel to set and grasp the relevant physiological parameters of the person in distress at the first time.

[0014] Preferably, the protective pad is a sealed bag structure, one side of the protective pad is connected to an air nozzle, and the oxygen mask inflates the protective pad through the air nozzle.

[0015] By adopting the above technical solution, the air nozzle is installed on the protective pad. In the actual rescue process, some people in distress suffer from drowning shock. At this time, the distress location is far from the shore, so on-site rescue is required; the protective pad is inflated through the air nozzle. At this time, under the buoyancy of the protective pad, the protective pad can float on the water surface, so the people in distress can be placed on the protective pad, and the protective pad plays a supporting role for the people in distress.

[0016] Preferably, two groups of magnets are embedded in one end of the protective pad away from the first aid box, the length of the protective pad is not less than three times the width of the first aid box, and iron blocks that are in contact with each group of magnets are embedded in the vertical end surface of the first aid box away from the connection with the protective pad.

[0017] By adopting the above technical solution, the magnet is embedded on the protective pad, and the length of the protective pad is set as above. When the device is in the storage state, the protective pad is wrapped around the first aid box, and the iron block of the first aid box is magnetically adsorbed to the magnet on the protective pad. The above setting realizes the connection between the protective pad and the first aid box, and the protective pad wrapped around the outer periphery of the first aid box plays a protective role on the first aid box.

[0018] Preferably, two groups of shoulder straps respectively buckled and connected to the waist belt are connected to a vertical end surface of one side of the first aid box body.

[0019] By adopting the above technical solution, each set of shoulder straps is connected to the vertical end face of one side of the first aid box body, and the shoulder straps are connected to the waist belt. Under the above coordination, the person in distress is not likely to fall off the protective pad.

[0020] Preferably, the waist belt is elastic, and the length of the waist belt is not greater than the sum of twice the length and width of the first aid box.

[0021] By adopting the above technical solution, when the belt is tied around the body of the person in distress, the belt can maintain a close fit with the person in distress due to its elasticity; and in the storage state, the belt is turned over, and the belt can wrap the protective pad on the periphery of the first aid box, further improving the fit between the protective pad and the first aid box.

[0022] Preferably, round holes for lifting are provided through the corners at both ends of the protective pad.

[0023] By adopting the above technical solution, after completing the cardiopulmonary resuscitation and rescue of the person in distress at the first time on the scene, the person in distress needs to be transferred to the hospital for further examination. The groups of round holes are located at the corners of the head and tail of the protective mat. At this time, the rescue personnel can pull the groups of round holes by hand to lift the protective mat, thereby improving the convenience of transferring the person in distress with the help of the protective mat.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By integrating all modules of chest compression, mechanical ventilation, physiological monitoring, and external defibrillation on the device, and the protective pad can be wrapped on the outside of the first aid box, the heart pump and chest pump theory are used in this application to effectively squeeze the heart and pump out more blood flow; the belt compression method does not have the "hammering" effect of traditional point compression, which reduces the harm to the patient. At the same time, the belt design increases the proportion of the belt wrapping the chest cavity to achieve a true 3D compression effect; by putting the defibrillator on the belt, the automatic defibrillation technology based on the biphasic exponential attenuation wave technology reduces the amount of current passing through the heart during defibrillation, effectively reducing the damage to the myocardial tissue; the multi-feature fusion ECG rhythm detection algorithm is used to ensure that the accuracy of diagnosis is above 95%;

[0026] 2. By sliding the neck pillow sleeve at the arc-shaped pillow opening, when the rescuer finds that there are debris in the mouth of the person in distress that needs to be cleaned, the rescuer pulls out the spring pin, and the neck pillow sleeve located inside the arc-shaped pillow opening is in a free state. The head of the person in distress falls on the neck pillow sleeve, and the rescuer turns the neck of the person in distress, and the head of the person in distress keeps turning. The above process improves the convenience of clearing foreign objects from the mouth of the person in distress and reduces the harm to the person in distress during the process of adjusting the position;

[0027] 3. By installing the air nozzle on the pad, during the actual rescue process, some people in distress may suffer from drowning shock, and the distress location is far from the shore, so on-site rescue is required; the protective pad is inflated through the air nozzle, and at this time, under the buoyancy of the protective pad, the protective pad can float on the water surface, so the people in distress can be placed on the protective pad, and the protective pad plays a supporting role for the people in distress.

Under the above cooperation, the person in distress 10 is not likely to fall off the protective pad 7. The waist belt 8 is elastic, and the length of the waist belt 8 is not greater than the sum of the length and width of the first aid box 1. The waist belt 8 can keep fitting with the person in distress 10; and in the storage state, the waist belt 8 is turned over, and the waist belt 8 can wrap the protective pad 7 on the outer periphery of the first aid box 1, further improving the fit between the protective pad 7 and the first aid box 1.

[0037] A hole is opened on the end surface of the side away from the protective pad 7 and a spring pin 13 is fixed thereon. A hole is opened on the annular surface of the side of the neck pillow sleeve 12 close to the spring pin 13 and is plugged into and matched with the spring pin 13. When the rescue personnel find that there are debris that need to be cleaned in the mouth of the person in distress 10, the rescue personnel will pull out the spring pin 13.
