Referring to fig. 1-2, fig. 1 is a perspective assembly view of a noninvasive ventilation mask 50 according to an embodiment of the present invention. Fig. 2 is a block diagram illustrating a control system 100 for a noninvasive ventilation mask according to an embodiment of the present invention.

The control system 100 of the noninvasive ventilation mask comprises a ventilator 60 and a noninvasive ventilation mask 50 connected with the ventilator 60; the noninvasive ventilation mask 50 is attached to the face of a human body, and when the respirator 60 detects that the noninvasive ventilation mask 50 is abnormally attached to the face of the human body, the noninvasive ventilation mask 50 is controlled to deform, so that the noninvasive ventilation mask 50 is adjusted to be attached to the face of the human body again.

The ventilator 60 includes a housing 10, a gas suction passage provided in the housing 10, a controller 30, and an inflation/deflation assembly 40.

The case 10 is used to mount the air supply assembly 20, the controller 30, and the air inflation and deflation assembly 40. The controller 30 is electrically connected to the air supply unit 20 and the air charge and discharge unit 40.

The gas supply assembly 20 is used to supply gas at a preset pressure. In the present embodiment, the air supply assembly 20 is in communication with the noninvasive ventilation mask 50, and when the noninvasive ventilation mask 50 is attached to the face of the human body properly, the air supply assembly 20 supplies air at a predetermined air pressure to the human body through the noninvasive ventilation mask 50.

The controller 30 is configured to set an air pressure for providing air to the human body, and when the air pressure is set, provide a predetermined flow rate of air through the air supply assembly 20, so as to form air at a predetermined air pressure in the noninvasive ventilation mask 50. In this embodiment, the controller 30 is used for periodically collecting the gas flow rate of the gas in the elbow 52, the controller 30 is further electrically connected to the inflation and deflation assembly 40, and the inflation and deflation assembly 40 is further connected to the airbag 54.

The inflation and deflation assembly 40 includes an inflation pump assembly (not shown) and a deflation valve (not shown), the inflation pump assembly and the deflation valve are connected to the air bag 54, and the controller 30 is electrically connected to the inflation pump assembly and the deflation valve to switch the air bag 54 between inflation and deflation states by turning on/off the inflation pump assembly and the deflation valve.

The inflator assembly includes an inflator (not shown) and a vent tube 412, with one end of the vent tube 412 communicating with the bladder 54 and the other end communicating with the inflator. The purge valve is disposed in the vent line 412.

Noninvasive ventilation mask 50 includes frame 51, elbow 52, nasal face cushion 53, and bladder 54.

The frame 51 has an interior cavity 511. The frame 51 is made of a hard material, so that the noninvasive ventilation mask 50 has rigidity, is not easily deformed, and has a certain supporting force.

One end of the elbow 52 is in communication with the frame 51 and the other end of the elbow 52 is in communication with the ventilator 60. In this embodiment, the ventilator 60 communicates with the other end of the elbow 52 via a gas inhalation pathway. The elbow 52 is used to communicate the noninvasive ventilation mask 50 with the air supply assembly 20. The elbow 52 is provided with an anti-asphyxia valve. One end of the elbow 52 is a mounting section rotatably connected to the frame 51, and the other end of the elbow 52 is a connecting section for connection to the gas suction passage.

The nose pad 53 is soft in material, can warp in order to laminate the user's face to a certain extent. Part of the nose pad 53 extends into the inner cavity 511 and is connected with the frame 51 in a sealing way, part of the nose pad 53 is positioned outside the inner cavity 511, and the nose pad 53 covers the face of the human body and is jointed with the face of the human body.

The air cell 54 is disposed within the nose pad 53. Specifically, the air bag 54 is disposed inside the nose pad 53 at an end remote from the frame 51. In this embodiment, the nose pad 53 includes a silica gel pad attached to the face of the human body, and the air bag 54 is disposed around the inside of the silica gel pad. For example, a cavity is provided at an end of the nose pad 53 remote from the frame 51, and the air bag 54 is disposed in the cavity. The inflation of the bladder 54 expands the nasal cushion 53.

The controller 30 detects whether the nose and face pad 53 is abnormally attached to the face of the human body according to the first airflow transmitted by the breathing machine 60 in the current period and the second airflow transmitted by the breathing machine in the previous period, and when the nose and face pad 53 is abnormally attached to the face of the human body, the controller 30 inflates the air bag 54 through the inflation and deflation assembly 40, so that the nose and face pad 53 is inflated to attach the nose and face pad 53 to the face of the human body again. Specifically, when the controller 30 detects that the difference between the first airflow rate of the current cycle and the second airflow rate of the previous cycle is greater than the preset threshold value, it is determined that the nose pad 53 is abnormally attached to the face of the human body. Specifically, when the difference between the first airflow of the current period and the second airflow of the previous period is greater than the preset threshold, it is proved that the airflow is increased dramatically, and when the noninvasive ventilation mask 50 is tightly attached to the face of the human body, the air supply assembly 20 needs to provide the airflow at the preset flow rate to maintain the preset pressure. When there is a gap between the noninvasive ventilation mask 50 and the human face, the air supply assembly 20 needs to provide an air flow several times or even tens of times greater than the preset flow rate to maintain the preset pressure. The controller 30 inflates the air bag 54 via the inflator and the air duct 412, causing the nasal cushion 53 to expand and reattach the nasal cushion 53 to the human face.

When the air bag 54 is in an inflated state, the controller 30 detects whether the nose and face pad 53 is abnormally attached to the face of the human body according to the third airflow and the second airflow of the current period transmitted by the respirator 60, and outputs a closing signal to the inflation and deflation assembly 40 to stop inflating the air bag 54 when the nose and face pad 53 is normally attached to the face of the human body. Specifically, when the air bag 54 is in the inflated state, the controller 30 detects that the difference value between the third airflow and the second airflow of the current cycle is smaller than the preset threshold value, and outputs a closing signal to the inflation and deflation assembly 40 to stop inflating the air bag 54. The second airflow is the normal airflow before the airbag 54 is inflated, that is, the normal airflow before the airflow is drastically increased, so the second airflow is set to the normal airflow.

Above-mentioned noninvasive ventilation face guard 50 through increase gasbag 54 in nose face pad 53 for noninvasive ventilation face guard 50 and human face laminating are unusual, aerify through gasbag 54 and make nose face pad 53 take place the inflation, thereby laminate nose face pad 53 in human face again, realize when monitoring noninvasive ventilation face guard 50 and human face laminating are unusual, the normal state of laminating between noninvasive ventilation face guard 50 and the human face of automatic adjustment.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, to the extent that such modifications and variations fall within the scope of the invention and the equivalent techniques thereof, it is intended that the present invention also encompass such modifications and variations.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, so that the present invention is not limited by the scope of the present invention.
