Description

Infant model for emergency treatment training}

The present invention relates to an infant model for first aid training, and more particularly, to an infant model for first aid training that enables training and evaluation of first aid measures such as CPR and airway obstruction under conditions similar to those of an actual infant body. .

Cardiopulmonary resuscitation (CPR) is a procedure that restores and revives cardiopulmonary function when cardiopulmonary function is severely reduced or stopped. Since the brain is irreversibly damaged 4 to 5 minutes after cardiac arrest occurs, the person witnessing the cardiac arrest must immediately start CPR to resuscitate the person in a normal state.

According to the Pediatric Basic Resuscitation Guidelines of the 2020 CPR Guidelines, the general public and healthcare providers will request rescue and a defibrillator when they find an unresponsive infant or pediatric patient. The general public should perform CPR immediately if the infant or child is not responding and is not breathing normally.

The health care provider checks for a pulse if the infant or child is unresponsive and not breathing normally, but the pulse check should not exceed 10 seconds. The health care provider checks the pulse in the infant's brachial artery. If the healthcare provider cannot feel a pulse within 10 seconds or is uncertain whether a pulse is present, begin chest compressions.

If the infant's pulse is greater than 60 beats per minute but breathing is inadequate, the healthcare provider should give rescue breaths at a rate of 12 to 20 beats per minute until spontaneous breathing is restored. The pulse is rechecked every 2 minutes and the pulse check time should not exceed 10 seconds. The health care provider initiates chest compressions when the pulse rate is less than 60 beats per minute and the perfusion is poor (i.e., the skin is pale, mottled, or cyanotic) even with oxygen and ventilation.

Asphyxative cardiac arrest is much more common in infants and children than cardiac arrest due to ventricular fibrillation. More than 90% of deaths due to foreign body aspiration occur in children under 5 years of age, of which 65% occur in infants.

In infants and children, when airway obstruction is severe, or when there is mild airway obstruction and progresses to a severe condition, coughing or vocalization becomes impossible. In children older than 1 year, if the provider determines that the airway obstruction is severe, perform abdominal thrusts under the diaphragm (Heimlich maneuver) until the foreign body comes out or until unconsciousness. For infants, the health care provider alternates between 5 back pats and 5 chest thrusts until the foreign body is expelled or unconscious.

Abdominal thrusting is not performed in infants because the ribs do not sufficiently protect the epigastric organs and the liver is relatively large, so there is a high risk of internal organ damage when the abdominal thrusting method is used. The healthcare provider initiates CPR if the infant patient is unresponsive or if there is no response during the foreign body removal procedure.

However, the medical provider looks into the mouth before breathing after chest compressions, and if a foreign body is visible, the foreign body is removed using a finger. Healthcare providers should not attempt to remove a foreign body by inserting a finger into the mouth when the foreign body is not visible, as doing so may force the foreign body deeper into the pharynx or damage the pharynx. After two artificial respirations, the medical provider repeats the chest compression and artificial respiration process until the foreign body is removed.

Since first aid such as CPR and airway obstruction is performed for infants, it is not appropriate for operators or trainers to repeatedly practice the above process. Therefore, there is a need for a device capable of training and evaluating first aid under conditions similar to those of an actual infant's body.

Figure 4a and Figure 4b is a cross-sectional view for explaining the operation of the artificial respiration training module. 5a to 5c are cross-sectional views for explaining an airway obstruction treatment process in an artificial respiration training module. 6A and 6B are cross-sectional views for explaining the operation of the non-return valve.

First, referring to FIGS. 4A and 4B, the artificial respiration training module 300 includes an artificial lung bag 310, a flexible tube 320, a displacement sensor 330 for artificial respiration, an elastic member 340, and a non-return valve 350.

The artificial lung bag 310 is disposed between the hinged first chest plate 113 and the second chest plate 114 within the torso 110 of the dummy 100 to store the supplied air, thereby providing a second air bag. The chest plate 114 is rotated. Based on the torso 110 of the dummy 100 lying horizontally, the second chest plate 114 may be disposed above the first chest plate 113.

The end of the second breast plate 114 close to the neck 140 is connected to the first breast plate 113 with a hinge axis parallel to the horizontal axis. The second chest plate 114 can rotate up and down by expansion and contraction according to the amount of air stored in the artificial lung bag 310 .

The artificial lung bag 310 may be fixed to the first chest plate 113 by a fixing connector 311 . The fixed connector 311 is connected to the flexible tube 320 to allow air to enter and exit the artificial lung bag 310 .

The flexible tube 320 supplies air injected from the mouth 152 of the dummy 100 according to the artificial respiration of the trainee to the artificial lung bag 310 . The flexible tube 320 is bent or unfolded according to the degree to which the head 150 of the dummy 100 is folded or retracted relative to the neck 140 to realize airway closure and airway opening. In the flexible tube 320, as the head 150 rotates back and forth, the part passing through the hole 142a of the neck rotation part 142 and the end of the chin guide 153a is bent or stretched, thereby realizing airway closure and airway opening. there is.

The displacement sensor 330 for artificial respiration measures the displacement of the second chest plate 114 according to the amount of air stored in the artificial lung bag 310 and outputs it to the control unit 600 . The displacement sensor 330 for artificial respiration may be mounted on the lower side of the second chest plate 114. The displacement sensor 330 for artificial respiration may be composed of various known displacement sensors.

When a trainee blows air into the artificial respiration through the mouth 152 of the head 150, the air is injected into the artificial lung bag 320 through the flexible tube 320 and the artificial lung bag 310 rises to perform artificial respiration. Respiratory volume can be measured through the displacement sensor 330 for measurement. The control unit 600 may obtain the respiratory volume, respiratory time, and respiratory rate based on the information measured by the displacement sensor 330 for artificial respiration.

The elastic member 340 applies elastic force to the second breast plate 114 in a direction in which the second breast plate 114 approaches the first breast plate 113 . The elastic member 340 is tensile deformed when the second chest plate 114 rotates upward according to the air injection of the artificial lung bag 310, and then elastically restoring force when the air injection of the artificial lung bag 310 stops. 2 Rotate the chest plate 114 downward. Accordingly, the elastic member 340 can quickly discharge air from the artificial lung bag 310 when artificial respiration is stopped and support the artificial lung bag 310 with elastic force.

For example, the elastic member 340 includes tension coil springs, one end of which is fixed to the second breast plate 114 and the other end of the first breast plate (341, see FIG. 11) by a spring holder (see FIG. 11). 113) can be supported. As another example, the elastic member may be made of a material such as rubber, and both ends may be fixed to the first and second chest plates 113 and 114.

To perform artificial respiration, open the airway using the head tilt-chin lift method. Or, in a state where the head cannot be moved due to a neck injury, the jaw thrust method is used to pull the chin forward to open the airway.

Because the back of the head is larger than that of adults, it is necessary to place a towel under the shoulders to offset the effect of the head bending forward relative to the chest. In general, when positioned correctly, the ear canal is at the same level as just in front of the shoulder. In a state where you are too bent or your head is too far back, you can rather block the airway.

As shown in FIG. 5A, when the head 150 is bent too far forward, the flexible tube 320 passes through the hole 142a of the neck rotation unit 142 and the end of the chin guide 153a and is bent. closure is implemented. In this state, as shown in FIG. 5B, when the head 150 is tilted back in an upright position by head tilt-chin lifting, the flexible tube 320 is formed through the hole 142a of the neck rotation unit 142 and the chin. The area passing through the end of the guide 153a is stretched to open the airway.

As shown in FIG. 5C, when the head 150 is tilted back too much by head tilt-chin lift, the area passing through the end of the hole 142a of the neck rotation unit 142 and the end of the chin guide 153a is bent and airway closure is implemented. Although not shown, the chin 153 may move vertically upward to open the airway using a chin-pushing method.

The backflow prevention valve 350 is mounted on the flexible tube 320 to prevent the air stored in the artificial lung bag 310 from flowing back into the mouth. The backflow prevention valve 350 allows air to be blown into the artificial lung bag 310 during artificial respiration, and after the artificial respiration is completed, the air in the artificial lung bag 310 is discharged to the outside to be discharged to the mouth 152. to block out the air.

For example, as shown in FIGS. 6A and 6B , the check valve 350 may include a valve housing 351 and a valve slide 356 .

The valve housing 351 has an inner space. The valve housing 351 has a valve inlet 351a, a valve outlet 351b, and an external outlet 351c. The valve inlet 351a is connected to the flow path of the flexible tube 320 and injects air according to artificial respiration into the inner space of the valve housing 351 . The valve outlet 351b is connected to the flow path of the flexible tube 320 and discharges the air in the inner space of the valve housing 351 to the artificial lung bag 310 .

The valve housing 351 may be fixed within the body 110 . The flexible tube 320 may be divided into two, and one end of the division may be connected to the valve inlet 351a, and the other end of the division may be connected to the valve outlet 351b. The external outlet 351c discharges the air in the inner space of the valve housing 351 to the outside.

The valve housing 351 may be configured and assembled in a divided form into first, second, and third housings 352, 353, and 354. Therefore, the valve housing 351 can be easily assembled by disposing the valve slide 356 between the first and second housings 352 and 353 separated from each other. In addition, the valve housing 351 can be easily assembled to the body 110 via the third housing 354 .

The first housing 352 has an inner space and has an open top and bottom. Here, the upper and lower sides of the first housing 352 are defined based on the body 110 lying horizontally. The valve inlet 351a communicates with the inner space of the first housing 352 . The lower opening of the first housing 352 is closed by the third housing 354 .

The second housing 353 has an inner space and is coupled to the upper opening of the first housing 352 in the form of an open lower side. The valve outlet 351b communicates with the inner space of the second housing 353 .

The guide block 353a protrudes from the upper bottom of the second housing 353 to limit the rising height of the valve slide 356 . The guide block 353a may have guide holes 353b penetrating vertically. The guide hole 353b may guide the elevation of the valve slide 356 by inserting an upper portion of the valve slide 356, for example, a guide rod 358. The external discharge port 351c may be formed by vertically penetrating the guide block 353a through the guide hole 353b.

The valve slide 356 is supported in the inner space of the valve housing 351 so as to be able to move up and down. The valve slide 356 rises by the air injected from the mouth 152 of the dummy 100 to the valve inlet 351a according to artificial respiration, and closes the external outlet 351c to the valve inlet 351a and the valve slide 356. Air is supplied to the artificial lung bag 310 by allowing air flow between the valve outlets 351b.

The valve slide 356 is lowered by the air flowing back from the artificial lung bag 310 to the valve outlet 351b in response to interruption of artificial respiration, thereby blocking the air flow between the valve inlet 351a and the valve outlet 351b. The external outlet 351c is opened to discharge air to the outside.

The valve slide 356 is a valve plate 357 that lifts and opens the upper opening of the first housing 352 in a closed state, and protrudes from the upper surface of the valve plate 357 to form a guide hole in the second housing 353. A guide rod 358 inserted into (353b) and guided up and down may be provided.

The valve slide 356 is maintained in a lowered state in the second housing 353 by its own load with the external outlet 351c open before artificial respiration is performed. At this time, the valve plate 357 is maintained in a lowered state by being guided by the guide rod 358 and the guide hole 353b to close the upper opening of the first housing 352 .

In this state, when artificial respiration is performed, the air injected into the mouth 152 moves into the inner space of the first housing 352 via the valve inlet 351a. Then, the valve plate 357 is guided by the guide rod 358 and the guide hole 353b and rises to come into contact with the guide block 353a, thereby closing the external discharge port 351c and moving the first housing 352. Open the upper opening of the Then, the air injected into the inner space of the first housing 352 is discharged from the valve outlet 351b through the inner space of the second housing 353, and is stored in the artificial waste bag 310.

Thereafter, when artificial respiration is stopped, the valve slide 356 descends in the inner space of the second housing 353 by air flowing backward from the artificial lung bag 310 to the valve outlet 351b. At this time, the valve plate 357 descends under the guidance of the guide rod 358 and the guide hole 353b to open the external outlet 351c while closing the upper opening of the first housing 352 . Then, the air flowing back into the inner space of the second housing 353 does not flow into the inner space of the first housing 352 and is exhausted to the outside through the external outlet 351c.

7 is a cross-sectional view showing an example in which the back tapping training module is mounted on the torso of the dummy. 8 is an exploded perspective view of FIG. 7 .

7 and 8 , the back tapping training module 400 includes a back tapping detection sensor 410, a back skin 420, and a pressing unit 430.

The back tapping detection sensor 410 is mounted on the back of the torso 110 of the dummy 100, detects whether tapping on the back is performed, and outputs it to the controller 600. Body 110 may have a mounting groove on the back. The tapping sensor 410 may be mounted in the mounting groove and electrically connected to the control unit 600 . The tapping sensor 410 may be formed of a pressure sensor such as a surface pressure sensor to detect whether tapping on the back is performed at the correct location and with the correct strength.

The back skin 420 is attached to the dummy 100 to cover the back tapping sensor 410 . The back skin 420 may be made of silicone or urethane rubber. The back skin 420 is configured to cover the mounting groove of the torso 110 and can be detached from the torso 110 .

The pressing unit 430 transmits the pressure applied to the back skin 420 to the back tapping sensor 410 . For example, the pressing unit 430 may be formed in the form of a plate wider than the tapping sensor 410 . The pressing part 430 is disposed to correspond to the tapping sensor 410, so that one end is fixed to the bottom of the mounting groove of the torso 100 and the other end can be freely disposed. That is, the pressing unit 430 may be mounted in the mounting groove of the body 110 in a cantilever manner.

The pressing part 430 is covered by the back skin 420. The pressing unit 430 may press the tapping sensor 410 by moving the free end around the fixed end due to the pressure applied to the back skin 420 during tapping on the back. As another example, although not shown, the pressing unit may be formed in the form of a protrusion on the inside of the back skin 420 to press the tapping sensor 410 on the back.

To treat an infant's airway obstruction, place the infant on the thigh with the head facing down, then tap the center of both scapulas 5 times with the palms down, and place the infant on the opposite thigh with the head facing down. After lying down, repeat 5 chest thrusts alternately until the foreign object comes out or until you lose consciousness. If the patient is unresponsive or is unresponsive during the foreign body removal procedure, the healthcare provider initiates CPR. The back tapping training module 400 of this embodiment enables back tapping training when treating an infant's airway obstruction.
