Abstract
A device, method and system improve the breathable air quality of the environment in the region of a specific part of a body, such as around the mouth and nose area of a person buried in an avalanche. The device includes at least one inlet, at least one pump, at least one power resource, a controller, and at least one outlet. An inlet of the pump is constructed to act as a chamber. A first end of the chamber is connected to the inlet and a second end of the chamber is an opening towards the outside of the device. When the pump is activated, the pump will provide a vacuum in the chamber and suck air from the surroundings into the pump through the second end of the chamber and the chamber.
Claims22
A device for improving the breathable air quality in an environment comprising:
- at least one inlet,
- at least one pump,
- at least one power resource,
- a controller, and
- at least one outlet
- wherein;
- the at least one inlet is connected with a pump inlet of the pump, and the at least one outlet is connected with a pump outlet of the pump,
- the inlet is constructed to act as a chamber wherein a first end of the chamber is connected to the pump inlet and a second end of the chamber is an opening towards the outside of the device, and
- the pump will, when activated, provide a vacuum in the chamber and suck air from the surroundings into the pump through the second end of the chamber and the chamber, and pump the air from the pump outlet to the outlet,
- wherein the device is integrated into the frame of a backpack, wherein the outlet is connected to the pump outlet via an air supply pipe, the air supply pipe being integrated into the backpack, and shoulder harness, the outlet being arranged in the shoulder harness close to a carrier's facial area.
A device for improving the breathable air quality in an environment comprising:
- at least one inlet,
- at least one pump,
- at least one power resource,
- a controller,
- at least one outlet, and
- one or more sensors,
- wherein;
- the at least one inlet is connected with a pump inlet of the pump, and the at least one outlet is connected with a pump outlet of the pump,
- the inlet is constructed to act as a chamber wherein a first end of the chamber is connected to the pump inlet and a second end of the chamber is an opening towards the outside of the device, and
- the pump will, when activated, provide a vacuum in the chamber and suck air from the surroundings into the pump through the second end of the chamber and the chamber, and pump the air from the pump outlet to the outlet,
- wherein the controller comprise an automatic activation unit for setting and controlling an operating mode of the pump, and
- wherein the sensors are sensitive to one or more of:
- movement caused by an avalanche, CO2 level above preset threshold, weight load/pressure, g-forces, power resource level, or sensor input crossing activation threshold, and
- the one or more sensors is connected via a sensor input interfaces to the automatic activation unit of the controller, wherein the controller comprise a program for monitoring the sensor readings and for controlling the operation mode of the device accordingly.
