First aid device used in case of airway obstruction {FIRST AID DEVICE FOR AIRWAY OBSTRUCTION}

The present invention relates to a first aid device used in case of airway obstruction, and more particularly, in an emergency situation where the airway is completely or partially obstructed by a foreign substance, etc., a conscious patient or rescuer supports a chair back to a point below the diaphragm. It relates to a first aid device that is operated to automatically pressurize and is used in case of airway obstruction.

In general, a foreign body caught in the throat and the airway completely or partially obstructed and the patient in a suffocating state is erected, and both arms are placed under the ribs from behind, and the area above the navel (below the diaphragm) is pulled diagonally upward. This should be repeated until the foreign object caught in the throat is removed.

At this time, in order to increase the airway pressure, it is necessary to induce a large pressure increase with great force. However, when adjacent rescuers other than the patient are weak, lack the physical strength to perform repeatedly, or have no knowledge about this, there is an inevitable problem of life-threatening accidents.

The first aid device 100 used in case of airway obstruction according to the present invention can be performed by a conscious patient himself in an urgent situation in which the airway is completely or partially blocked by foreign substances, etc., or an adjacent rescuer has no relevant knowledge or is weak in physical strength. Even in this case, the invention was devised to quickly remove foreign substances by supporting the chair back 20 and automatically pressurizing the point below the diaphragm to increase the airway pressure.

As shown in FIG. 1, the first aid device 100 used in case of airway obstruction according to an embodiment of the present invention includes a casing 110, a string member 120, a pressing member 130, and an entry/exit means 112. ) and a control means 160.

Specifically, the casing 110 is an enclosure that forms the outer shape of the entry/exit means 112 of the first aid device 100 used when the airway is obstructed according to an embodiment of the present invention. Inside the casing 110, an internal space 111 in which a part of the entry/exit means 112 and the string member 120 are accommodated is formed.

In addition, one side of the casing 110 may be provided with a pair of hook parts 116 formed in a ring shape to be fixed to the back of the chair back 20 .

Here, the chair is a conventional chair having a chair back 20, and it is preferable to use a chair having a width smaller than the width of the user's torso 10. Even when the width of the chair back 20 is greater than the width of 10)), the string member 120 under the ribs by crumpling clothes into the space created inside the string member 120 surrounding the body 10 and the chair back 20 ) can be used in close contact. This is a method that can be used when the pressure of the pressing member 130 is not well transmitted because the subcutaneous fat layer is thick.

In addition, a joint 118 made of an elastic material may be provided on the side of the casing 110 to which the hook 116 is coupled so that there is no floating space between the back of the chair back 20 and the hook 116. . As shown in the enlarged view of FIG. 2, the joint 118 is for preventing rattling when the entry/exit means 112 is operated by creating a separation space between the chair back 20 and the casing 110. will be.

The string member 120 is a string that tightens the torso 10 of a user who is pulled out from the casing 110 and sits on a chair, that is, a patient whose airway is partially or completely blocked by a foreign substance, etc., and is formed of a non-elastic material. It is formed in a length that can sufficiently wrap the body 10 and includes a length adjustment unit 122.

The length adjustment unit 122 is configured to tightly wrap the patient's torso 10, and even when sufficient force is applied, such as a belt, Velcro, button, or loop, the string member 120 is a large limitation if it is a means that does not loosen or unwind. There is no part, but it must be worn with a simple operation in an urgent situation.

The pressing member 130 is positioned so as to come into contact with the patient's torso 10, that is, under the diaphragm, and is fastened to the string member 120, and may have a hemispherical shape of a clenched fist.

When the pressing member 130 is fastened to the string member 120, it is preferably firmly fixed. This is because the position of the pressing member 130 fastened to the string member 120 should not be changed by the resistance force opposing the force of the pressing member 130 toward the body 10 by the operation of the entry/exit means 112. .

The entry/exit means 112 is built into the casing 110, and is configured to pull the string member 120 so that the pressing member 130 half-presses the patient's torso 10, that is, below the diaphragm.

As an example of the entry/exit means 112, as shown in FIGS. 2 and 3, when the actuator A controlled by the control means 160 operates, the tee rod T moves linearly in the forward and backward directions.

One end of the actuator (A) is coupled to the inner surface of the casing (110) adjacent to the chair back (20), and the tee rod (T) coupled to the other end performs linear motion on the same line.

A tee rod (T) refers to a 'T' shaped rod.

Here, when the tee rod (T) is 'advance' to the inner space 111 inside the casing 110, the tee rod (T) is pulled out long from the actuator (A), and as shown in FIG. 3, the tee rod (T ) The pressing member 130 presses the body 10 by the string member 120 that is caught in the 'ㅡ' shape and drawn in.

In addition, when the tee rod (T) is moved toward the actuator (A) from the inner space (111) inside the casing (110), the tee rod (T) enters the actuator (A), and the restoring force of the compressed body (10) The string member 120 is drawn out of the casing 110 by the resistance force described above.

At this time, when the string member 120 is moved in and out of the casing 110, a guide portion 113 may be formed on an outer surface (see FIG. 1) or an inner surface of the casing 110 to prevent twisting.

In addition, although not shown, the means for pulling the string member 120 into the inner space 111 of the casing 110 may also be made of a winding device. The principle is the same. When the string member 120 that tightly tightens the body 10 is pulled out of the casing 110 and pulls the string member 120 into the inner space 111 of the casing 110 at high speed, the pressing member 130 is to press the torso 10, and this operation is repeated to increase the airway pressure.

The control means 160 allows the patient or an adjacent rescuer to control the operation of the input/output means 112, and as shown in FIG. 1, it can be operated by a cable directly connected to the inside of the casing 110.

In addition, although not shown, the pressing repetition cycle of the pressing member 130 and the moving distance (pressing intensity) of the tee rod T may be adjusted and selected in the form of a dial.

These control means 160 include smart phones, tablet PCs, mobile phones, personal digital assistants (PDAs), media players, global positioning system (GPS) devices, e-book readers, digital broadcasting terminals, navigation devices operated by patients or adjacent rescuers. It may be, but is not limited to, kiosks, MP3 players, digital cameras, consumer electronics, and other mobile or non-mobile computing devices.

In addition, the control unit 160 may be a wearable terminal such as a watch, glasses, hair band, and ring having a communication function and a data processing function. The control unit 160 is not limited to the above, and a terminal capable of web browsing may be used without limitation.

On the other hand, the first aid device 100 used in case of airway obstruction according to an embodiment of the present invention further includes a thigh cuff 150 having one end connected to the pressing member 130 and the other end wrapped around the thigh, It can be done.

The thigh cuff 150 may be worn on one thigh as shown in FIG. 2 or may be worn on both thighs as shown in FIG. 3 . As a means to be worn, Velcro or the like may be used.

By adjusting the position of the thigh cuff 150 worn on the thigh, a force pulling the pressing member 130 connected by the connecting member 140 toward the thigh is formed.

That is, as shown in FIG. 5 , if the pressure member 130 acts horizontally in the direction of force ① by the entry and exit means 112, the force of the connection member 140 fixed to the thigh cuff 150 When the direction (②) acts vertically and ultimately the direction (F) of the force acts diagonally, when the pressing member 130 presses the lower part of the diaphragm, the connection member fixed to the thigh cuff 150 ( 140, a material having a predetermined elastic force), the pressing member 130 pushes the diaphragm toward the chest.

In addition, the size of the restoring force (resistance described above) of the torso 10 compressed by the connecting member 140 and the thigh cuff 150 may be added.

Therefore, the first aid device 100 used in case of airway obstruction according to an embodiment of the present invention requires rapid emergency treatment for a patient with airway obstruction due to a foreign substance, and the patient himself or an adjacent rescuer can easily move the chair back 20 By fixing and supporting the casing 110, the control means 160 is operated so that the pressure member 130 repeatedly presses the lower part of the diaphragm of the patient to increase the airway pressure so that foreign substances blocking the airway can be removed. .

In particular, by providing the thigh cuff 150, when the pressure member 130 presses the patient's diaphragm, the diaphragm can be pushed up toward the chest, and the position where the thigh cuff 150 is worn can be adjusted to The diaphragm of patients of various body types can be pressed to push upward toward the chest.

In addition, when the pressing member 130 is formed in a clenched fist to press the patient, the protruding portion 132 protrudes toward the torso 10 to increase the pressure. This can be useful for people with a thick subcutaneous fat layer.

On the other hand, the first aid device 100 used in case of airway obstruction according to the present invention has the technical characteristics described in the present invention, and can be made in various shapes, shapes, standards, etc., as well as the above-described embodiment and a mixture of variants.
