DETAILED DESCRIPTION

In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described features. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

In one embodiment, referring to Figures 1-5, the utility model proposes an adjustable positive pressure ventilation oronasal mask, comprising an oronasal mask body 10 and a face fitting portion 20; a side of the mask body 10 away from the face fitting portion 20 is also connected to a ventilator for assisting a user wearing the adjustable positive pressure ventilation oronasal mask to maintain normal human breathing.

The side of the oronasal mask body 10 facing the facial fitting part 20 matches and fits the human face, and adjustment devices 11 are respectively provided at both ends of the oronasal mask body 10, and the ends of the adjustment devices 11 are provided with a first magnetic body 12; second magnetic bodies 22 are correspondingly provided at both ends of the facial fitting part 20, and the opposite surfaces of the second magnetic body 22 and the first magnetic body 12 can attract each other; an adhesive layer 21 is provided on the side of the facial fitting part 20 facing away from the oronasal mask body 10.

The interior of the mouth-nose mask body 10 is a hollow structure, and the facial fitting portion 20 matches the human face.

When the user needs to use the adjustable positive pressure ventilation oronasal mask, first clean the grease on the user's face to prevent bubbles from being generated when the adhesive layer 21 of the facial fitting part 20 is matched and bonded with the user's face, resulting in unstable bonding. After the facial fitting part 20 is matched and bonded to the user's face, the oronasal mask body 10 is aligned with the user's nose and mouth and then turned upside down on the user's face, and then the oronasal mask body 10 is magnetically connected to the user's face through the first magnetic body 12 on the adjustment device 11 and the second magnetic body 22 on the facial fitting part 20, so that the oronasal mask body 10 is fixed on the user's face, which can shorten the time for the oronasal mask body 10 to be worn or removed relative to the facial fitting part 20, thereby shortening the time for the adjustable positive pressure ventilation oronasal mask to be worn or removed, and the steps are simple. Even if the user needs to use a ventilator to assist breathing in time in some emergency situations, the adjustable positive pressure ventilation oronasal mask of the utility model can be quickly worn, so that the user will not miss the best wearing time.

Moreover, the side of the oronasal mask body 10 facing the facial fitting portion 20 matches and fits the human face, so the nasal mask body 10 can tightly fit the skin near the nose, preventing air leakage when the user wears the adjustable positive pressure ventilation oronasal mask, thereby affecting the use effect of the ventilator.

In a specific embodiment, referring to FIG. 1 , the adhesive layer 21 is made of a medical adhesive tape. In this way, when the facial adhesive portion 20 is attached to the user's face through the medical adhesive tape, the user's face will not feel a large foreign body, and the facial adhesive portion 20 has a simple structure; and when the user uses the adjustable positive pressure ventilator mouth and nose mask and tears off the facial adhesive portion 20, the user's face will not have an indentation like wearing a headband, which will not affect the aesthetics of the user's face, thereby improving the user's experience.

Moreover, the facial fitting portion 20 is disposable. When the user uses the adjustable positive pressure ventilation oronasal mask again, a new facial fitting portion 20 will be replaced, but the oronasal mask body 10 still needs to be repeatedly cleaned and disinfected to reduce the risk of cross infection for the user.

Moreover, the material of the disposable facial fitting portion 20 is non-woven fabric, soft silicone, hydrogel or a composite material similar to a medical mask. Thus, compared with the headband of the existing positive pressure ventilation mouth and nose mask made of a fabric composite or other special materials, the manufacturing cost of the facial fitting portion 20 of the utility model is lower.

In one embodiment, referring to FIG. 1 , at least one fixing portion 141 is provided at each end of the mouth-nose mask body 10, and each fixing portion 141 is sleeved with an adjustment device 11, which is used to adjust its length. The adjustment device 11 is preferably a Velcro or elastic band.

Because the size of the user's face is not uniform, some are large and some are small, an adjustment device 11 that can adjust its own length is provided to enable the oronasal mask body 10 to be tightly worn on the user's face.

In one embodiment, referring to FIG. 2 , at least one row of second magnetic bodies 22 are respectively disposed at both ends of the face fitting portion 20 , and each row includes at least two horizontally arranged second magnetic bodies 22 .

Specifically, the two ends of the facial fitting part 20 in this embodiment are respectively provided with two rows of second magnetic bodies 22, which match the two adjustment devices 11 respectively provided at the two ends of the oral and nasal mask body 10, so that the oral and nasal mask body 10 and the facial fitting part 20 can be connected more stably and not easily dropped. If an adjustment device 11 is respectively provided at both ends of the oral and nasal mask body 10, the connection between the oral and nasal mask body 10 and the facial fitting part 20 will be unstable and easy to drop; if three or more adjustment devices 11 are respectively provided at both ends of the oral and nasal mask body 10, the cost will increase and the cost performance is not high.

Each row of the second magnetic bodies 22 is preferably provided with three second magnetic bodies 22 arranged horizontally, so that the adjustment device 11 can have three adjustment amounts (the three adjustment amounts are large size, average size, and small size respectively). When the first magnetic body 12 of the adjustment device 11 is connected to the second magnetic body 22 in the middle, the adjustment amount of the adjustment device 11 is average size, which can meet the wearing needs of most users; when the first magnetic body 12 of the adjustment device 11 is connected to the second magnetic body 22 closest to the mouth and nose mask body 10, the adjustment amount of the adjustment device 11 is large size, which can meet the wearing needs of users with larger face sizes; when the first magnetic body 12 of the adjustment device 11 is connected to the second magnetic body 22 farthest from the mouth and nose mask body 10, the adjustment amount of the adjustment device 11 is small size, which can meet the wearing needs of users with smaller face sizes.
