Description

Portable automatic ventilating assistant device

The present invention relates to a portable automatic artificial respiration aid, and more particularly, to a patient's condition, that is, while allowing artificial respiration control by automatically pumping an air bag to supply air or gas necessary for breathing to patients. Including the sensor unit and auxiliary battery to measure vital signs in real time, it can provide the optimal amount of respiration according to the patient's condition, as well as its simple configuration and easy to carry, so it can be used in emergency situations outdoors. It relates to automatic ventilation aids.

A ventilator is a tool made for artificial respiration control by allowing air or gas necessary for respiration to enter and exit the lungs.

Conventionally, a manual ventilator for providing artificial respiration to a patient in an emergency situation such as CPR or acute respiratory failure or a surgical environment requiring general anesthesia, that is, a method in which a user manually applies pressure to an air bag to provide artificial respiration. It was mainly used, but there are disadvantages in that it is difficult to continuously provide a constant tidal volume due to different methods of applying pressure depending on the user and various physical characteristics such as hand size and grip strength.

In addition, there is a problem in that it is difficult to meet the demand with only a manual ventilator these days, when the number of critically ill patients is rapidly increasing due to Corona 19 because medical staff must continuously pressurize and pump the air bag by the patient's side.

Accordingly, in recent years, devices for automatically pumping air bags according to the patient's condition have been developed. Automatic pumping devices for ventilators and ventilators are shown.

First, the automatic pumping device of the ventilator disclosed in Republic of Korea Patent Publication No. 10-2151159 is characterized in that it is possible to control the number of respirations and to adjust the respiration volume suitable for adults and infants, but the patient's condition Since it is impossible to grasp, it is impossible to control the respiration volume according to the patient's condition, and it is difficult to use when power supply from the outside is not possible. .

In addition, the medical ventilator disclosed in Korean Patent Application Laid-Open No. 10-2019-0095031 checks the user's heart rate or oxygen saturation in real time, and controls the operation of the driving motor and the timing belt accordingly. The amount of air supplied to the patient can be controlled according to the user, that is, the patient's condition, but it is difficult to use when power supply from the outside is not possible. If an abnormality occurs in the pressurizing means, it cannot be used, so there is a disadvantage in that it cannot be prepared for an emergency situation.
