It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The following describes in detail a respiratory mask and a ventilation therapy device provided in the embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 1 to 5, embodiments of the present application provide a respiratory mask, comprising: a pad 10, a headband tube 20, and a rear headband; the cushion 10 comprises opposite first and second sides, the first side having a ventilation cavity for receiving the mouth and/or nose of a patient, the cushion 10 being provided with at least one opening, the opening being in communication with the ventilation cavity; the headgear tube 20 communicates with the opening, the headgear tube 20 being configured to secure the cushion 10 in an effective treatment position on the patient's face and to deliver an airflow to the ventilation cavity through the opening; the head band tube 20 surrounds at least partial areas of the two sides and the top of the face of the patient in use, at least two connecting parts 30 are respectively arranged at the positions of the head band tube 20, which are close to the left ear and the right ear of the patient, and at least two connecting parts 30 are arranged along the length direction of the head band tube 20; the rear head band surrounds at least a partial region of the patient's rear brain, and both ends of the rear head band are respectively connected to the connection parts 30.

Specifically, as shown in fig. 1 to 5, the respiratory mask includes a cushion 10, a headgear tube 20, and a rear headgear. The cushion 10 typically comprises a flexible material, such as a silicone material, for achieving a good fit with the patient's face. The cushion 10 includes opposite first and second sides, the first side of the cushion 10 being the side closest to the patient's face and the second side of the cushion 10 being the side away from the patient's face when the respiratory mask is worn by the patient. The first side of the cushion 10 has a ventilation cavity that can accommodate the mouth and/or nose of a patient. The cushion 10 is provided with at least one opening in communication with the ventilation chamber through which an air flow may be introduced to the ventilation chamber to maintain a positive pressure within the ventilation chamber for effecting treatment of the patient. A material with higher strength can be arranged on the second side of the gasket 10 to support the gasket 10, so that the gasket 10 is prevented from being deformed greatly.

The headband tube 20 may be made of a flexible material, which may be, but is not limited to, silicone, fabric, and the like. The headband tube 20 is of hollow tubular structure and communicates with the opening of the cushion 10. The headband tube 20 has mainly the following two functions: first, headgear tube 20 is capable of securing cushion 10 in an effective treatment position on the patient's face, in use, around both sides of the patient's face and at least a portion of the top of the head; second, headgear tube 20 communicates with the ventilator end tubing and delivers airflow into the ventilation cavity through the opening.

The headband tube 20 is arranged around two sides of the face of the patient, at least two connecting parts 30 are respectively arranged at the positions close to the left ear and the right ear of the patient, and the connecting parts 30 close to the left ear of the patient and the connecting parts 30 close to the right ear of the patient can be symmetrically arranged. At least two connection parts 30 are arranged along the length direction of the head pipe 20, and the length direction of the head pipe 20 is the flowing direction of the gas. The rear headband surrounds at least a partial region of the patient's rear brain, and both ends of the rear headband are connected to the connection parts 30, respectively. By arranging at least two connecting parts 30 at the positions of the headband tube 20 close to the left and right ears of the patient, the connecting position of the rear headband on the headband tube 20 can be changed, and the two parts are matched to realize the adaptive adjustment according to the head size of the patient. The back headband can be made of fabric, foam and other materials in a compounding mode, and the tightness degree of the back headband and the connection position on the headband tube 20 can be adjusted to adjust the position of the breathing mask on the face of a patient and the tightness degree of the pad 10 attached to the face of the patient.

As shown in fig. 1 and 2, which are left views of cheeks of a patient, the breathing mask is worn by the following method: extends from the lower nasal end of the patient through the face to the top of the head, i.e., the patient wears the mask with the perimeter of the cushion 10 and headgear tube 20 engaged and secured. The lower nose end may be defined as point a, the overhead position as point B, and the posterior headgear occipital position as point C. A. The three points B, C form a triangular positioning shape to secure the mask to the patient's head. Meanwhile, the headband tube 20AB is simplified to AO and BO, the O point is the position where the connecting portion 30 is located, that is, the position where the rear headband and the headband tube 20 are combined, so AO is the portion of the headband tube 20 corresponding to the lower portion of the connecting portion 30, BO is the portion of the headband tube 20 corresponding to the upper portion of the connecting portion 30, and the rear headband is simplified to be the segment CO. For example, when a patient with a relatively small head circumference wears a suitable mask, the fitting positions are the top of the head (point B) and the lower edge of the nose (point a), wherein point a is the most important to ensure sealing, the rear headband is connected to the connecting part 30 located in the middle position among the three connecting parts 30 shown in fig. 5 according to the head shape size of the patient with a small head circumference, and the most comfortable position is the most suitable position to wear, and for example, the most comfortable position to wear can be measured by the angle between the rear headband and the horizontal (i.e., the angle between the CO extension line and the horizontal line), the degree of the angle between the most suitable position is alpha, and the headband tube 20 extends to the top of the head (point B) and the lowest point (point C) of the rear headband along the lower edge of the nose. When a patient with a large head circumference wears a mask of the same size, the rear head band is loosened while maintaining the same fitting position (point a seals the mouth and nose), as shown in fig. 2. If the original position of the connecting portion 30 is to be maintained at the original rear headband angle α (if the position of the connecting portion 30 is not adjusted, the rear headband angle is β, β > α, and the angle degree at which the rear headband angle is adjusted to the optimum position by adjusting the position of the connecting portion 30 is α), the position of the connecting portion 30 needs to be adjusted, and the rear headband is adjusted from the connecting portion 30 originally connected to the intermediate position to the connecting portion 30 connected to the lowermost position.
