Description

CPR simulator {Simulator for training of CPR}

The present invention relates to a cardiopulmonary resuscitation simulator, and more specifically, to the general public, inexperienced workers and doctors, nurses, emergency rescue technicians, such as a professional cardiopulmonary resuscitation that can be trained in the same way to perform CPR on the human body It's about the simulator.

Cardiopulmonary resuscitation (CPR) is an emergency treatment that artificially circulates blood and helps breathing when a heart attack occurs. The basic steps of CPR include the consciousness checking step to check the condition of the patient, the step of asking for help to someone nearby immediately when it is confirmed that there is no consciousness. Respiratory confirmation phase to determine the pulse rate of the carotid artery, chest compressions to press the heart of the patient with the heart stopped, airway to lift the jaw by lifting the head to prevent airway obstruction due to the relaxation of the tongue muscle Phases, the ventilation step of blowing air into the lungs of the patient whose breathing is stopped, and then the chest compressions and respirations are repeated repeatedly until the paramedics arrive at the site.

 Respiratory confirmation is the process of determining the presence or absence of breathing in the reaction confirmation phase. The general public should check the reaction and report to 119 if there is no reaction, and then determine the presence or absence of breathing and abnormality according to the guidance of the emergency medical counselor. At the same time, the medical practitioner must check the reaction and determine whether there is a breathing or abnormality, and if it is determined that there is no reaction and not normal breathing, it should be recognized as a cardiac arrest situation. An important breath that requires judgment during abnormal breathing is cardiac arrest breathing. Cardiac arrest may be present in the patient at about 40% of the initial 1 minute after cardiac arrest, and recognizing cardiac arrest as a symptom of cardiac arrest is a very important factor in the rapid progress of cardiopulmonary resuscitation and resuscitation success. If there is no reaction but shows normal breathing, take a restorative posture to prevent aspiration of foreign body in the mouth.

The airway securing step is a step prior to resuscitation, where one hand is pressed against the forehead of the cardiac arrest and the palm of the patient's head tilts backwards, while the other hand's fingers pull the bones of the lower jaw toward the head to support the chin. Use the head tilt and chin method to tilt the subject back.

 Ventilation is an important component in CPR, and efficient ventilation is essential for the survival of cardiac arrest patients. The artificial respiration method is artificial respiration over one second, and the breathing amount is 500 to 600 ml, which is enough to visually confirm the chest rise. During chest compressions, care should be taken to ensure that ventilation is not performed at the same time, and that excessive ventilation should not cause hyperventilation.

In recent years, training using simulators has become commonplace for effective CPR in the emergencies. However, according to the related art, training for breathing confirmation of the patient is not properly performed because there is no function for the generation of respiratory sounds or the up and down movement of the chest in the breathing check phase training, which is an important factor in cardiopulmonary resuscitation. In addition, when proper CPR is performed, there is a problem in that there is no change in the patient's condition such as whether breathing is restored and the training lacks realism.

It is an object of the present invention to provide a CPR simulator that allows the CPR training to be carried out in a realistic manner in order to effectively perform first aid in the event of an emergency patient.

Cardiopulmonary resuscitation simulator according to the present invention for achieving the above object is installed in the interior of the human body model to output a respiratory sound similar to the respiratory sound of the actual human body, and is installed in the oral part of the head An air injection unit formed to enable injection of external air, a flow rate detection unit installed inside the head unit to detect the amount of air injected into the air injection unit, an air transfer unit connecting the air injection unit and the flow detection unit; An airway closure part installed on the air transport part to control a flow of fluid moved through the air transport part, and installed inside the body part to fill the fluid, and the body part expands and expands according to the amount of fluid introduced therein; An air storage unit capable of contraction and communicating with the air storage unit to supply fluid to the air storage unit or For discharging a portion of air-based fluid storage And a control unit for controlling the operation of the air pumping unit, the respiratory sound output unit, the flow rate detecting unit, and the air pumping unit.

Through the cardiopulmonary resuscitation simulator of the present invention can systematically and repeatedly train the use of cardiopulmonary resuscitation and defibrillator for professional emergency rescue workers, such as doctors, nurses, emergency rescue, etc., the person in charge of training to record and evaluate the training situation By doing so, you can make sure that the training is conducted effectively. In addition, it is possible to provide training for cardiopulmonary resuscitation and defibrillator use so that not only professional paramedics but also the general public can effectively administer first aid in an emergency.

In addition, since the CPR simulator of the present invention can be simulated closer to the actual human body, the user is not close to the actual human body CPR process, consciousness confirmation, breathing confirmation, pulse confirmation, chest pressure, airway secured, artificial Training to use breathing, defibrillator or AED. Therefore, it is possible to increase the proficiency according to the repetitive practice, and the trainer trained through the CPR simulator may not feel heterogeneity when faced with the actual human body.

And, in the conventional simulator, the pupil reflex, pulse driving, spontaneous breathing was manually operated, but the CPR simulator of the present invention automatically when the use of the appropriate CPR and defibrillator was made according to the built-in scenario program, Pulse driving, spontaneous breathing, and normal electrocardiogram signaling are implemented to enable realistic training.

The present invention will now be described in detail with reference to the accompanying drawings. The same reference numerals are used for the same components, and repeated descriptions and detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted. Embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

1, the CPR simulator 100 according to an embodiment of the present invention includes a human body model 110, an output unit, an air injection unit 130, a flow rate detection unit 140, and air. The sending unit 150, the airway closing unit 160, the air storage unit 170, the air pumping unit 180, and a control unit.

The human body model 110 may be formed in a shape similar to that of an actual human body. The human body model 110 has an appearance according to a standard human body shape and may be covered with skin of silicone or urethane material similar to the elasticity of the actual skin. The human body model 110 includes a head portion 111 having an oral portion 112 formed therein, and a body portion 113 having the head portion 111 formed on one side thereof. Joints of the head 111 and the body portion 113 may be designed to reproduce the degree of freedom of the human joint.

The respiratory sound output unit 120 is installed inside the human body model 110 and outputs a respiratory sound similar to the actual respiratory sound of the human body. The breathing sound output unit 120 may output a normal breathing sound, apnea and cardiac arrest breathing sound of the actual human body. During the CPR training of the user, the respiratory sound similar to the actual human breathing sound is generated from the respiratory sound output unit 120 so that the user can realistically perform CPR training.

Air injection unit 130 is installed in the oral cavity 112 of the head 111 is formed so that the outside air can be injected. The air injection unit 130 may be formed to penetrate the oral cavity 112 corresponding to the oral cavity of the human body in the head 111.

The flow rate detection unit 140 is installed inside the head 111 to detect the amount of air injected into the air injection unit 130. As such, as the flow rate detecting unit 140 is located in the head 111, the air introduced through the air injection unit 130 and the water mixed therein are discharged to the rear of the head 111 during the artificial respiration training. Therefore, it is not refluxed and can be prevented from infection by the saliva of others during the resuscitation training. The total amount of air injected by the user through the air injection unit 130 may be obtained by integrating flow rate data of the detected flow rate detection unit 140. An example of the flow rate detection unit 140 may be a flow rate sensor or a differential pressure sensor.

The air transfer unit 150 connects the air injection unit 130 and the flow rate detection unit 140. One end of the air transfer unit 150 is fixed to the air injection unit 130, the free end is fixed to the flow rate detection unit 140 located in the head 111 of the human body model 110 to deliver the user's air. do. One example of the air transfer unit 150 may be a tube.

The airway closure unit 160 is installed on the air transfer unit 150 to control the flow of fluid that is moved through the air transfer unit 150. When the user secures the airway of the human body model 110 in the course of performing the artificial respiration training, the airway obstruction unit 160 is in a state in which the airway is opened, that is, the air transfer unit 150 is in communication. do. Airway obstruction (160) is in the airway open state in the airway closed state when the airway secured for artificial respiration. The detailed structure of the airway obstruction 160 for this will be described later.

Air storage unit 170 is installed in the body portion 113 is formed so that the fluid is filled. The body 113 may be expanded and contracted according to the amount of fluid introduced into the air storage unit 170. The air storage unit 170 is not made to communicate with the air injection unit 130 and the air transfer unit 150, it is installed independently of the body portion 113. Air storage unit 170 may be made of a size and shape similar to the lungs of the actual human body.

The air pumping unit 180 is disposed to communicate with the air storage unit 170. The air pumping unit 180 supplies fluid to the air storage unit 170 or The fluid of the air storage unit 170 is discharged. When the air pumping unit 180 supplies fluid to the air storage unit 170, as the air storage unit 170 expands, the body 113 of the human body model 110 also expands. On the contrary, when the fluid is discharged from the air storage unit 170 by the air pumping unit 180, as the air storage unit 170 contracts, the body portion 113 of the human body model 110 also contracts to the initial state. Is restored. An example of the air pump 180 to implement this may be an air pump 181 or a blower fan.

Meanwhile, unlike the above-described structure, in the structure in which the air injection unit, the air transfer unit, and the air storage unit are sequentially communicated, the air stored in the air storage unit by the other user is blown back while the user blows the air and the user's mouth There is a possibility to flow into. However, in the cardiopulmonary resuscitation simulator 100 of the present invention, since the air injection unit 130 into which the air is introduced and the air storage unit 170 in which the air is stored are arranged independently of each other without being in communication with each other, The problem may not occur.

The control unit controls the operations of the respiratory sound output unit 120 , the flow rate detection unit 140, and the air pumping unit 180. An example of the control unit may be a microprocessor, and the microprocessor may receive information of various sensors and output an actuator driving signal.

Through the CPR simulator 100 having the above structure, the cardiopulmonary resuscitation training for professional emergency rescue workers such as doctors, nurses, and emergency rescuers can be systematically and repeatedly trained. In addition, cardiopulmonary resuscitation training is available to enable effective emergency treatment in emergency situations as well as professional emergency rescue workers.

In addition, since the CPR simulator 100 of the present invention can be simulated closer to the actual human body, the user can perform the actual CPR training without the actual human body. Therefore, it is possible to increase the proficiency according to the repetitive practice, the trained through the cardiopulmonary resuscitation simulator 100 may not feel heterogeneity when performing the procedure to face the actual human body.

In addition, since the air injecting unit 130 and the air storage unit 170 are independently disposed as described above, the CPR simulator 100 of the present invention salivary to another user in the process of performing CPR training. CPR training can be conducted under hygienic conditions because no air is introduced to the user.

On the other hand, the control unit is the breathing sound output during the respiration check training and the vertical movement of the body portion 113 of the human body model 110 can be implemented at the same time, the respiratory sound output unit 120 and the air pumping unit 180 To work together . The controller may operate the air pump 180 to correspond to the amount of air measured in real time by the flow rate detector 140 during the ventilation training.

In more detail, when the user breathes into the air injection unit 130 of the CPR simulator 100 of the present invention, the flow rate is detected in the flow detection unit 140, the control unit is a user to actually breathe By judging, the air pump 180 is operated to cause the trunk portion 113 of the human body model 110 to expand and contract. The user sees the expansion and contraction state of the body portion 113 and confirms that the artificial respiration is effectively performed.

On the other hand, the above-described control unit detects the air flowing into the air injection unit 130 during the artificial respiration training in the flow rate detection unit 140 so that the expansion of the air storage unit 170 in proportion to the amount of fluid detected It is preferable to drive the air pumping unit 180. This may allow the air storage unit 170 to expand only as much as the amount of air blown by the user through the air injection unit 130 so that the user may feel higher in reality during the artificial respiration training process.

On the other hand, as an example of the structure of the air storage unit 170 may include a first storage unit 171 and the second storage unit 172.

The first storage unit 171 is disposed on the left side of the inside of the body portion 113 of the human body model 110.

The second storage unit 172 is disposed on the right side of the inside of the body portion 113 of the human body model 110.

The first storage unit 171 and the second storage unit 172 may be formed in a shape similar to the lungs of the actual human body. The first storage unit 171 and the second storage unit 172 may be formed so as not to communicate with each other. Here, the control unit controls the air pump 180 to expand and contract independently of the first storage unit 171 and the second storage unit 172, respectively.

On the other hand, as an example of the structure of the above-described respiratory sound output unit 120 may include a first speaker 121, a second speaker 122, and a third speaker 123.

The first speaker 121 is installed inside the head 111 of the human body model 110. Through the first speaker 121, the breathing sound generated in the oral cavity of the human body may be output.

The second speaker 122 is disposed above the inside of the body portion 113 of the human body model 110. Through the second speaker 122, the respiratory sound generated in the actual breast part of the human body may be output.

The third speaker 123 is disposed below the inside of the body portion 113 of the human body model 110. Through the third speaker 123 may be a breath sound generated in the back portion of the actual human body.

From the first speaker 121, the second speaker 122, and the third speaker 123, a respiratory sound similar to that generated in the actual human body is output so that the user can hear these sounds with the ears and make the human body feel as if the human body is revived. In fact, you can do CPR training. In addition, after the user completes the CPR training The stethoscope may be positioned on the torso 113 of the human body model 110 and listen to the breathing sound output from the second speaker 122 so that the human body may feel revived.

On the other hand, referring to Figure 3, as an example of the structure of the airway closure 160 may include a fixing portion 161, the first pressing portion 162, the second pressing portion 163. Here, it will be described on the assumption that the air transfer unit 150 is made of a tube of a specific length.

Fixing portion 161 is fixedly coupled to one side of the neck portion of the body portion 113, is installed adjacent to the air transfer portion 150.

The first pressing part 162 is fixed to the fixing part 161 and is formed to be in close contact with the air transfer part 150. For example, the first crimping unit 162 may be a stainless steel pipe.

The second pressing portion 163 is rotatably coupled to the fixing portion 161 and fixedly coupled to the head 111. The second compression unit 163 seals or opens the air transfer unit 150 while rotating based on the fixing unit 161 according to the rotation of the head 111. As an example of the shape of the second crimping portion 163 for this purpose, while being formed in an arc shape, it may be eccentrically coupled to the fixing portion 161.

On the other hand, in general, in order to perform artificial respiration in the actual human body, the airway securing process of opening the airway is performed first. In the same way, the user does not lean the head 111 of the human body model 110 against the torso 113 during the artificial respiration training, and thus the second compression unit 163 is positioned adjacent to the first compression unit 162. In the initial state that the flow of the fluid is blocked by a portion of the air transfer unit 150 is compressed, the user secures the airway head 111 of the human body model 110 against the torso 113 and lifts the jaw When the second compression unit 163 is rotated with respect to the fixing unit 161, a portion of the air transfer unit 150 that is compressed is opened to allow the user to inject air through the air injection unit 130. Can be in a state capable of artificial respiration.

Here, since the second pressing part 163 eccentrically rotates according to the rotation of the head 111 compresses the air transfer part 150 by the rolling contact without slipping, the airway blocking reliability is high and the air transfer part 150 is Damage can be minimized.

Meanwhile, referring to FIG. 4, the pump 181 and the noise reducer 184 may be included as an example of the structure of the air pump 180 described above.

An inlet 182 through which air is introduced is formed at one side of the pump 181, and a first outlet 183 through which air is discharged is formed at the other side.

An internal space is formed in the noise reducer 184. The noise reducer 184 is formed to surround at least a portion of the pump 181 so that the inlet 182 is exposed and the first outlet 183 is not exposed. One side of the noise reducer 184 is formed with a second outlet 185 through which air is discharged.

As described above, the noise reducer 184 is installed to cover at least a portion of the air pumping unit 180 to reduce noise generated by the air pumping unit 180. As the noise of the air pump 180 is reduced by the noise reducer 184, the breath sound output from the breath sound output unit 120 may be more easily heard by the user.

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be.
