Referring to FIGS. 1 and 2, a CPR training apparatus according to an embodiment may be used in CPR exercises for infants.

Cardiopulmonary resuscitation performed for infants is briefly described below. CPR for infants may be performed when there is no consciousness or breathing, no spontaneous movement, or abnormal breathing or seizures. First, the infant resets the infant immediately, then pats his / her foot to see if he or she is conscious and rests normally. Then, after collecting the indexes and stops, the chest compressions are performed by pressing the first stance part in contact with the sternal part of the infant. The compression position corresponds to the area immediately below the center of the line connecting the nipple areas of the infant. After chest compressions have been performed on the infant, the infant's ears and the floor are parallel with one hand with one hand, and then the infant's head (102) is tilted backward with the other hand to inflate the infant's mouth and nose simultaneously. Breathing. Cardiopulmonary resuscitation for infants is performed through repetition of chest compression and artificial respiration.

The CPR training apparatus 1 according to an embodiment can assist effective training of artificial respiration performed on an infant. The CPR training device 1 may include a mannequin 10, an artificial lung 11, and a breathing module 12.

The mannequin 10 may be a human-like model. The mannequin 10 may be shaped to have a shape similar to a human body, for example, a shape conforming to a standard body shape of an infant so that the user may feel similar to a real emergency situation. The mannequin 10 may include a head 102 and a body 103.

The head 102 may have a shape similar to the head 102 of the infant. An airway 101 for artificial respiration may be formed in the head 102. The airway 101 can be formed inside the head 102 through the oral and nasal cavities communicating with each other.

The body 103 may have a shape similar to an infant's body. The body 103 may include a torso, an arm, and a leg. A xiphoid process, a rib, a nipple, or the like may be represented on the outer surface of the body 103. Thus, when the user performs chest compressions on the body 103, the correct chest compression position can be identified. Inside the body 103, a configuration for CPR training can be arranged. The body 103 can be formed in an openable structure for installing, replacing, and inspecting parts inside.

The artificial lung 11 may be provided inside the body 103 of the mannequin 10. For example, the artificial lung 11 may be disposed at the thoracic region of the mannequin 10. The artificial lung 11 may be provided with an air bag that becomes bulky when air is injected. According to this structure, when the air is injected into the artificial lung 11 through the artificial respiration, the thorax of the mannequin 10 is bulged upward, so that it is possible to provide a feeling similar to performing artificial respiration to a real person.

2 to 4, the breathing module 12 can connect the airway 101 and the artificial lungs 11. The air flow path between the airway 101 and the artificial lung 11 is formed through the respiration module 12 so that the air injected into the airway 101 can be introduced into the artificial lung 11 according to the performance of the artificial respiration have. The artificial lung 11 may include a fluid portion 122, a filter portion 121, a recoil prevention portion 124, and an air amount measurement portion 123.

The flow portion 122 can provide a flow path of air from the airway 101 to the artificial lungs 11. The flow section 122 includes a plurality of flow tubes and the plurality of flow tubes are connected to each other by connecting the filter section 121, the rebreathing prevention section 124, the air amount measuring section 123 and the artificial lung 11 , And one air passage from the airway 101 to the artificial lung 11 can be formed.

The filter unit 121 can remove foreign matter from the air injected into the manikin 10 through the airway 101. The filter portion 121 is detachably connected to the moving portion 122, so that the filter portion 121 can be easily replaced after collecting a sufficient amount of foreign matter.

Referring to FIG. 5, the filter unit 121 may include a collecting housing 1211 and a foreign matter filter 1212.

One side of the collecting housing 1211 may be connected to the airway 101, and the other side may be connected to the moving part 122. The collecting housing 1211 may include a space formed therein. In this case, the air injected from the airway 101 can pass through the internal space of the collecting housing 1211 during the flow. The collecting housing 1211 may be composed of a pair of assemblable segments 1211a and 1211b.

The foreign matter filter 1212 can prevent foreign matter from flowing into the artificial lung 11 in the artificial respiration training process. The foreign matter filter 1212 may be provided inside the collecting housing 1211. The air passing through the inner space of the collecting housing 1211 can flow toward the artificial lung 11 via the foreign matter filter 1212. [ The foreign matter filter 1212 can pass only the gas. In other words, various foreign substances such as saliva and sputum can be caught by the foreign matter filter 1212 and removed from the air injected into the collecting housing 1211. The foreign matter filter 1212 can be coupled to the pair of segments 1211a and 1211b constituting the collecting housing 1211 through ultrasonic welding.

The filter portion 121, for example, the collecting housing 1211, may be detachably connected to the fluid portion 122. With this structure, the artificial lung 11 and other configurations of the breathing module 12 can be used semi-permanently, since only the filter section 121 can be selectively and easily replaced from the breathing module 12. Therefore, maintenance of the apparatus is easy, and the cost of replacement can be reduced.

The re-breathing prevention portion 124 can prevent the air inside the artificial lung 11 from flowing backward in the airway 101 direction. In other words, the re-breathing prevention unit 124 causes the air injected from the airway 101 to flow in the direction of the artificial lung 11 through the artificial respiration operation so that the air inside the artificial lung 11 flows through the airway 101 It can be prevented from coming out. The rebreathing prevention part 124 may be connected to the artificial lung 11 at one side and the fluidizing part 122 at the other side.

6 and 7, the rebreathing prevention portion 124 may include a first housing 1241, a second housing 1242, and a sealing member 1244.

The first housing 1241 may be provided with an inlet 1243a communicating with the flow portion 122. The air injected from the moving part 122 can be introduced into the first housing 1241 through the inlet 1243a.

The second housing 1242 can communicate with the first housing 1241. That is, the air introduced into the first housing 1241 can flow into the second housing 1242. The second housing 1242 may include an inlet 1243b communicating with the artificial lung 11 and an outlet 1243c communicating with the outside of the mannequin 10.

The sealing member 1244 is disposed inside the first housing 1241 and can move in the air flow direction. Closure member 1244 may comprise a rubber material. The sealing member 1244 may be selectively in contact with one of the inlet 1243a and the outlet 1243c in accordance with the flow direction of the air. Specifically, when the air is introduced into the first housing 1241 from the inlet 1243a, the sealing member 1244 can be brought into close contact with the outlet 1243c. In this case, air introduced into the first housing 1241 may flow into the artificial lung 11 through the inlet 1243b of the second housing 1242. [ On the other hand, the sealing member 1244 may be in close contact with the inlet 1243a when air is discharged from the artificial lung 11, that is, when air is introduced from the inlet 1243b to the second housing 1242 . Accordingly, the air inside the second housing 1242 can be discharged to the outside of the mannequin 10 through the outlet 1243c. As a result, the re-breathing prevention part 124 adjusts the direction of flow of the air injected into the airway 101 through artificial respiration and the air discharged from the artificial lung 11, Which can be used to perform artificial breathing exercises.

2 to 4, the air amount measuring unit 123 can measure a flow rate of air flowing into the airway 101 according to the air flow rate flowing through the flow channel 122, that is, the artificial respiration operation . The air amount measuring unit 123 may include a flow rate measuring sensor 1243 and a connection valve 1231.

The connection valve 1231 is connected to the flow portion 122 so that the air passing through the flow portion 122 can flow through the flow rate measurement sensor 1243. [ The flow measurement sensor 1243 measures the flow rate of the air flowing through the connection valve 1231 and can detect the amount of artificial respiration of the user performed on the airway 101.

The air amount measuring unit 123 can measure the user's artificial respiration performance state by measuring information of the flow rate of the air flowing in the flow unit 122, the flow rate, the air injection period, and the like.
