Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0030] Such as figure 1 Shown: In order to ensure the tightness when wearing and improve the convenience of use, the present invention includes a casing 1 and a casing cavity 4 arranged in the casing 1; at least two sealing rings are arranged in the casing cavity 4 The membrane 5 and the sealing ring membrane 5 are evenly distributed inside the casing 1 and the sealing ring membrane 5 is close to the mouth of the housing cavity 4, and several sealing ring membranes 5 in the casing 1 are stacked; the casing 1 covers the face for ventilation At the same time, several sealing ring films 5 can be in contact with the face, so as to enhance the sealing state when the casing 1 is attached to the face.

[0031] Specifically, the casing 1 and the sealing ring film 5 are all made of materials that meet medical standards. The casing 1 is in the shape of a mask, and the s...

Abstract

The invention relates to a seal face mask with stacked films. According to the technical scheme provided by the invention, the seal face mask with stacked films comprises a mask housing and a mask body cavity formed in the mask housing. At least two circles of seal ring films are arranged in the mask body cavity, are evenly distributed in the mask housing and are close to the mouth portion of themask body cavity, and a plurality of seal ring films in the mask housing are stacked. When the face mask is put on the face for respiration, the multiple seal ring films can be in contact with the face to strengthen the seal state when the mask housing attaches to the face. At least two circles of seal ring films are arranged in the mask housing, the seal ring films are stacked, two or more seal ring films are utilized to be in contact with the face, the layering sense of seal can be effectively improved, the reliability of seal is improved, the seal ring films can be matched with an alimentary canal catheter through positioning grooves and connecting seal pieces, the alimentary canal catheter is prevented from affecting the sealing performance during venting of the mask, and the seal facemask is convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to a mask, in particular to a laminated film sealing mask, which belongs to the technical field of medical devices. Background technique [0002] The tightness of the mask during ventilation is very important, and reliable sealing is an important criterion for judging the practicability of the mask. At present, most clinical masks are sealed by airbag compression. In most patients, the airtightness is sufficient to meet clinical needs, but it is inconvenient to inflate the airbag before use. For patients with gastric tube insertion or duodenal nutrition tube insertion, the current mask ventilation can not effectively support the patient's mask breathing because of the gaps formed between the two sides of the tube body and the patient's skin, resulting in a large amount of gas leakage. [0003] In response to this situation, various measures have been adopted clinically, such as: setting the catheter through holes on the mask, and...
