## Abstract

A modular portable anti-choking device featuring multiple suction patterns controlled via embedded computing programs is disclosed. The device incorporates an air propeller to generate suction, user-type settings for customizations, and pressure sensors for safety. A dual power supply system enables portability. The compact design makes it suitable for use in various environments including homes, restaurants, and any other settings. Its modular structure allows for easy disassembly, cleaning, and reassembly, making it easy for repeated use. The device ensures effective, safe, adaptable, and reliable operation by dynamically adjusting suction strength based on user-type and real-time sensor data, while minimizing the risk of airway injury caused by excessive suction pressure.

## Claims

### Claim 1

A modular, portable anti-choking comprising: a facemask configured to form an airtight seal over a patient's mouth and nose: a modular arrangement of air chambers connecting the facemask to a suction mechanism configured to guide airflow: a high-velocity propeller unit configured to generate negative pressure to dislodge airway obstructions: one or more filters configured to capture dislodged debris and prevent it from entering the propeller unit: a dual-power supply system operable with both an AC power source and rechargeable batteries: a control interface elements configured to receive user inputs for patient type, suction strength and suction pattern: sensors configured to monitor air pressure and detect debris motion within the air chambers; and control circuitry embedded with a computing program configured to manage suction operations dynamically based on user selections and real-time sensor feedback; wherein the control circuits store computing programs that is configured to manage suction operations including suction strength and suction patterns for different usage scenarios and safety; and wherein the control circuits is configured to automatically alter the suction pattern and strength or stop suction altogether, based on real-time data from the sensors.

### Claim 2 (depends on 1)

The device of claim 1, wherein the control interface is configured to include selection of patient types such as, baby, child, and adult, each mapped to a corresponding safe suction range.

### Claim 3 (depends on 1)

The device of claim 1, wherein the suction patterns comprise pulsed suction, intermittent suction, and hybrid suction.

### Claim 4 (depends on 1)

The device of claim 1, wherein the suction strength levels comprise low, medium, and high.

### Claim 5 (depends on 1)

The device of claim 1, wherein the sensors are placed within one or more of the air chambers and provide real-time feedback to adjust suction power or cease operation.

### Claim 6 (depends on 1)

The device of claim 1, wherein the device has a modular design allowing disassembly, cleaning, and reassembly of the facemask, air chambers, propeller unit, and power supply.
