Electric suction device for emergency airway obstruction removal

Abstract

Disclosed herein are embodiments of an electric suction device for emergency airway obstruction removal and anti-choking, relating to the field of emergency rescue technology. One embodiment comprises a face mask, with an electric suction mechanism set on the surface of the face mask. The electric suction mechanism includes an oral support that is movably installed inside the face mask. The face mask is pressed tightly against the face and adjusted to form a sealed space. Activating the electric suction mechanism switch triggers the control circuit board to power the one-way suction module via the battery. This controls the one-way suction module to extract air, creating negative pressure in the sealed space. Consequently, the obstructing object is suctioned out of the airway due to continuous negative pressure. When the patient is unconscious or unable to cooperate, the oral support can be inserted into the patient's mouth to ensure that the patient's mouth is open and the device can be used. This device is easy to operate, safe and stable. The suction of this device can be controlled and there are different types of masks that can be configured to meet different people. It can be used independently by the patient without third-party assistance, or by a rescuer when the patient is unable to perform self-rescue.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(7) The following provides a further detailed description of the invention in conjunction with the embodiments:

Embodiment 1

(8) As shown in FIGS. 1-5, this invention provides an electric suction device for emergency airway obstruction removal, comprising a face mask 1, with an electric suction mechanism 2 installed on the surface of the face mask 1, and a wearing connection mechanism 3 set on the surface of the electric suction mechanism 2. The electric suction mechanism 2 includes an oral support 201, which is movably installed inside the face mask 1. A shell 204 is movably installed at the bottom end of the oral support 201, with exhaust holes 207 evenly distributed on the bottom of the shell 204. A suction tube (202) is fixedly installed within the electric suction mechanism 2. One end of the tube is exposed outside the shell 204 to facilitate assembly with the movable face mask 1, while the other end extends into the interior of the shell (204). The electric suction mechanism 2 also includes a battery 210 fixedly installed inside the shell 204. A control circuit board 209 is fixedly installed at the bottom of the battery 210. A charging interface 205 is fixedly installed on the surface of the control circuit board 209 and extends to the surface of the shell 204. A button transmission component 208 is movably installed on the surface of the charging interface 205, with a press switch 206 fixedly installed at the bottom of the button transmission component 208. The press switch 206 is movably installed on the surface of the shell 204. A one-way suction module 203 is set on the surface of the control circuit board 209 and fixedly installed inside the shell 204, with its top end compatible with the suction tube 202.

(9) In this embodiment, the face mask 1 is placed over the patient's mouth and nose and adjusted to form a sealed space. The battery 210 supplies power to the control circuit board 209 and the one-way suction module 203. When the press switch 206 is pressed, it pushes the button transmission component 208 to activate the control circuit board 209 inside the shell 204. At this point, the control circuit board 209 triggers the battery 210 to power the one-way suction module 203, controlling it to suction outward unidirectionally. Due to the constant negative pressure, objects in the patient's mouth are sucked out of the airway, while air is expelled through the exhaust holes 207. If suction is unsuccessful, try again after a second or more times, and it can work. One end of the oral support (201) can be securely affixed within the mask and connected to the electric suction mechanism 2, while the other end is inserted into the patient's mouth. The oral support effectively separates the patient's teeth, thereby maintaining an open mouth without penetrating deeply into the throat, thus ensuring safety. The mouth is supported and forms a channel with the airway. When the electric suction mechanism 2 is not in use, the battery 210 can be charged by connecting a charger to the charging interface 205. Additionally, different sizes of masks are used to fit different people to improve the adaptability of the device.

Embodiment 2

(10) As shown in FIGS. 1-5, based on Embodiment 1, this invention provides a technical solution: preferably, the wearing connection mechanism 3 includes a casing 301 fixedly installed on the surface of the shell 204. There are two sets of casings 301 distributed on the surface of the shell 204. A retractable band 302 is movably connected to the surface of the casing 301. Hook-and-loop fasteners (loop side) 303 are fixedly installed on the surface of the retractable band 302, and hook-and-loop fasteners (hook side) 304 are also fixedly installed on the surface of the retractable band 302. The wearing connection mechanism 3 also includes a support column 307 movably installed inside the casing 301. A rotating disk 305 is movably installed on the surface of the support column 307. A mainspring 308 is fixedly installed on the surface of the support column 307, with one end of the mainspring 308 fixedly installed on a fixed column 306. The fixed column 306 is fixedly installed on the surface of the rotating disk 305 and on the surface of the retractable band 302. A stopper rod 310 is movably connected to the surface of the retractable band 302 and fixedly installed inside the casing 301. A limit rod 309 is fixedly installed at one end of the retractable band 302.

(11) In this embodiment, when the retractable band 302 is stretched, it drives the rotating disk 305 to rotate inside the casing 301. The rotation of the rotating disk 305 drives the mainspring 308, while the fixed column 306 and support column 307 work together to compress the mainspring 308. The hook-and-loop fasteners (loop side) 303 and hook-and-loop fasteners (hook side) 304 on both sides of the retractable band 302 are connected and fixed to the patient's head. When use is completed, the retractable band 302 is released, and the mainspring 308 recoils, driving the rotating disk 305 to rotate and retract the retractable band 302. At this time, the stopper rod 310 clamps the retractable band 302 to prevent it from tangling while retracting. When the limit rod 309 reaches the surface of the casing 301, the retractable band 302 is reset. This device can remain stable even if the rescue personnel briefly let go during the use of the electric suction mechanism 2, better assisting rescue personnel in saving patients and improving the device's adaptability.

(12) The following specifically explains the working principle of this electric suction device for emergency airway obstruction removal.
