Monitoring system for manual ventilator and controlling method of the same}

The present invention relates to a monitoring system for a manual ventilator and a control method thereof, and more specifically, to a monitoring system for a passive ventilator and a control method thereof that can improve the patient's prognosis and minimize side effects.

A manual ventilator (bag-valve-mask, BVM) can be used at the pre-hospital stage and within the hospital, and refers to equipment that can manually help patients breathe. A typical manual respirator consists of a mask, a valve, and a bag, and performs artificial respiration in such a way that when a rescuer applies pressure to the bag, appropriate air is injected into the patient through the valve and mask.

During artificial respiration, indicators such as appropriate respiratory rate, ventilation capacity, and inspiratory pressure may be set differently depending on the patient's age or pathological condition. However, conventional manual respirators are not equipped with a system that can monitor the indicators in real time, so artificial respiration is performed depending on the rescuer's repeated experience and practice.

If an inexperienced rescuer or an inexperienced rescuer uses a manual ventilator, there is a possibility that the patient's prognosis may be adversely affected due to asynchrony between the injected air and the patient's breathing cycle, insufficient or excessive ventilation capacity, etc.

To prevent this, manual respirators can be equipped with monitoring equipment, but since the monitoring equipment, which is electronic equipment, is not easy to attach and detach, there is a problem that manual respirators are not easy to sterilize and are vulnerable to infection.

Therefore, the development of a monitoring system for a manual ventilator that is easy to attach and detach and can simultaneously monitor ventilation indicators may be considered.

Korean Patent Publication No. 10-2016-0132159 discloses a pressure sensor-based electric respiratory system with real-time breathing control. Specifically, we disclose an electric respiratory system that assists breathing by processing data from a pressure sensor through a microprocessor and controlling the blower in real time by applying an optimized algorithm.

However, it is difficult to apply this type of powered respiratory system to a manual ventilator consisting of a mask, valve, and bag. Furthermore, a monitoring structure using sensors other than the pressure sensor is not disclosed.

Korean Patent Publication No. 10-1808691 discloses a critical patient respiratory monitoring system and method. Specifically, a critical patient respiratory monitoring system and method is disclosed that can monitor a patient's respiratory information by placing a sensing element inside the airflow pipe of a ventilator.

However, in this type of monitoring system and method, the sensor for monitoring is fixed to the airflow pipe, making it difficult to attach and detach. Accordingly, it is difficult to disinfect manual respirators and there is a possibility that they may be vulnerable to the spread of infection.

Further comprising a control unit that receives at least one of the user's personal information and the target operation of the ventilator and transmits it to the monitoring unit,
Monitoring system for passive ventilators. According to paragraph 1,
The monitoring unit,
Capable of mutual communication between user terminals and data,
Monitoring system for passive ventilators. According to paragraph 1,
The valve is,
A cover that is detachably coupled to the coupling hole and seals the coupling hole when coupled to the coupling hole to block the flow of air passing through the coupling hole.
Monitoring system for passive ventilators. (a) a step of detachably coupling the monitoring unit to the valve of a manual ventilator;
(b) the monitoring unit measuring the flow rate and pressure of air passing through the valve;
(c) a calculation unit calculating at least one of the user's respiratory rate, ventilation capacity per minute, ventilation capacity per minute, inspiratory pressure, and artificial respiration operation time based on the measurement results;
(d) the calculation unit deriving an artificial respiration method appropriate for the user based on the calculation results; and
(e) comprising outputting the calculation and derivation results of the calculation unit to at least one of a display unit, an external service server, and a user terminal,
Control method of a monitoring system for a manual ventilator. According to clause 11,
Before step (d) above,
(d0) a step in which the monitoring unit receives at least one of the user's personal information and the target operation of the ventilator from the outside is performed,
Control method of a monitoring system for a manual ventilator. According to clause 11,
After step (d) above,
(d1) a step in which the calculation unit determines whether the operation of the ventilator corresponds to an operation according to the artificial respiration method appropriate for the user derived by the calculation unit, based on the measurement results of the flow rate and pressure of air passing through the valve. performed,
Control method of a monitoring system for a manual ventilator. According to clause 13,
After step (d1) above,
(d2) When the calculation unit determines that the operation of the ventilator does not correspond to the operation according to the artificial respiration method appropriate for the user derived by the calculation unit, a step of sending a warning signal to the outside is performed,
Control method of a monitoring system for a manual ventilator.
