Description

The ventilator is a self-

The present invention relates to a passive ventilator assist device.

The Bag-Valve Mask (BVM) is one of the devices that are useful for artificial ventilation for patients with cardiac arrest and respiratory arrest.

In general, the BVM is used for administering a high concentration of oxygen to help maintain a stable ventilation of emergency patients or an intensive care unit. When the patient is unable to breathe by himself or herself, the BVM supplies oxygen directly to the patient, It is a device for effect like resuscitation.

Accordingly, Korean Utility Model Registration No. 20-0329009 describes a firefighter portable oxygen ventilator.

Effective management at an appropriate time in a situation where airway is not maintained and ventilation and oxygenation is not possible can be an important factor in determining patient survival and death, restoration and impairment of normal function.

However, there are few methods that can be used to verify whether a ventilator is provided with adequate ventilation when a ventilator is provided to a patient by using a BVM that is widely used. In practice, hyperventilation and high volume ) Induced artificial respiration increases the pressure of the thorax, which interferes with the amount of blood flow into the heart, which has been reported to have an important effect on the prognosis and survival rate of patients with cardiac arrest.

Although the emphasis is on avoiding the provision of respiration, many published literature in the adult or pediatric population still provides frequent hyperventilation in CPR, hypoventilation due to insufficiency of inspiratory volume, resulting in hypoxemia, And the state is deteriorated.

That is, the one-time respiratory volume and the artificial respiratory rate should be adjusted according to the patient's condition. Since the conventional artificial respirator is only dependent on the experience of the firefighter or the professional operator, And the first aid was not performed properly.

Accordingly, the present invention has been developed in order to improve a conventional artificial respiratory apparatus, and it is possible to evaluate data measured by a sensor and to stably administer and maintain an appropriate one-time respiratory amount according to a patient's respiratory state, And an object of the present invention is to provide a manual air-assisted breathing apparatus capable of continuously monitoring the state of a patient.

The above object can be achieved by a gas supply system comprising a gas supply part formed with a gas flow passage to which gas is supplied and connected to a mask which is connected to a bag to supply gas to the bag, A first sensing unit coupled to the first sensing unit for sensing ventilation information including a gas supply amount flowing into the gas supply unit, a notification unit for processing and displaying ventilation information sensed by the first sensing unit, Wherein the first sensing unit and the power supply unit are integrally modularized and are coupled to the gas supply unit.

And a second sensing unit coupled to the gas supply unit and sensing whether the bag and the gas supply unit are connected to each other. When the bag sensing unit senses that the bag and the gas supply unit are coupled by the second sensing unit, And is provided to supply additional power.

The notification unit may further include an input unit for inputting an instruction period for informing a user of a gas injection timing.

Accordingly, the present invention can quantify and quantify the gas supply amount that can not be measured by the conventional artificial respirator, and display the quantified gas supply amount so that anyone can easily use it in an emergency situation.

Furthermore, medical accidents caused by the use of the wrong ventilator can be prevented, and the quality of the medical service can be improved.

In addition, since the portable device can be easily miniaturized, it can be prepared in emergency situations at any time, and it is possible to monitor the state of the patient and the once-supplied amount by the sensor, so that it is possible to respond appropriately to the medical condition according to the patient's condition.

In addition, when a bag, an oxygen respirator or the like is connected to the passive ventilator assist device of the present invention, it is operated within a short period of time, so that emergency treatment can be performed even in an urgent situation.

Figure 2 is a cross-sectional view of a passive ventilator assistant device, mask and bag of the present invention.
3 is a perspective view of a passive ventilator assistant device of the present invention.

The preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which the technical parts already known will be omitted or compressed for the sake of brevity.

The manual ventilator assist device 100 of the present invention includes a gas supply unit 110, a first sensing unit 120, a second sensing unit 130, a notification unit 140, an input unit 150, and a power supply unit 160, And will be described with reference to FIGS. 1 to 3. FIG.

The gas supply unit 110 is a tubular component having a gas flow passage for supplying gas, one side of which is connected to the bag B to receive gas, the other side of which is shielded from the outside, And supplies the gas supplied from the bag B to the mask M while being connected to the mask M. [

At this time, one side of the gas supply unit 110 is preferably provided so as to be compatible with various devices such as a conventional bag or an oxygen supply device for assisting gas supply, an end-tidal carbon dioxide measurement device, and the like.

It is preferable that the other side of the gas supplying unit 110 is provided so as to be compatible with the conventional mask M. In this example, a predetermined fitting means (not shown) is provided on the outer circumference of the other side of the gas supplying unit 110, So that the coupling with the various masks (M) of the mask can be easily performed.

The first sensing unit 120 is a component that is provided on the gas supply unit 110 and continuously senses the ventilation information including the supply amount of the gas supplied from the gas supply unit 110 and the partial pressure of the gas.

It is also possible to detect the supply amount of the gas (patient's end-tidal gas) supplied from the mask M, the partial pressure of the gas, and the like.

Further, the above-mentioned ventilation information includes the gas supply amount and the gas partial pressure information as described above, and includes information to be considered in ventilation such as the number of gas supply per unit time, the number of times of patient breathing per unit time, and the like .

The second sensing part 130 is provided outside the gas supplying part 110 and detects whether the bag B is connected to the gas supplying part 110. The second sensing part 130 senses whether the bag B is connected to the gas supplying part 110, And the gas supply unit 110 are connected to each other, a power supply unit, which will be described later, is provided to supply power to the passive ventilator assistant apparatus 100.
