Description

Technical Field

[0001] The utility model relates to the technical field of ventilation treatment equipment, in particular to a continuous positive pressure ventilation mask. Background Art

[0002] Ventilation therapy equipment is an important medical device in modern medicine. It is mainly used for the treatment of various respiratory diseases or sleep breathing disorders with continuous positive airway pressure ventilation, which can assist in the treatment of sleep apnea. In ventilation therapy, in order to provide therapeutic gas to the wearer, it is usually necessary to wear a mask on the wearer's head. The existing ventilation masks currently have facial silicone pads that do not fit the position of the human face. During the oxygen supply process of the ventilator, oxygen is easy to leak from the bridge of the nose and cheeks. The connection between the frame of the ventilation mask and the facial silicone pad is not tight, which is also easy to cause air leakage, thereby reducing the amount of oxygen inhaled by the user and endangering the user's health. In addition, the existing ventilation masks are worn for a long time and are prone to pressure sores on the human face, causing discomfort to the wearer. Therefore, a continuous positive airway pressure mask is needed. Utility Model Content

[0003] The utility model provides a continuous positive ventilation mask, which can effectively solve the above problems.

[0004] The utility model is achieved in this way:

[0005] The utility model provides a continuous positive airway pressure mask, comprising: a frame, a mask pad, a forehead silicone pad, a curved pipe and a hook, wherein the frame comprises a frame body covering the mouth and nose of a wearer, a forehead bracket arranged on the forehead of the wearer, and a connecting bracket connecting the frame column and the forehead bracket; a connecting hole for connecting the curved pipe is provided on the frame body; a headband hanger for connecting the hook is provided at a position close to the cheek of the frame body; a plurality of card blocks are provided on a side of the frame body away from the connecting hole; the mask pad is used to contact the face of the wearer, and the mask pad The mask pad is detachably connected to the frame, comprising a frame cover for clamping the frame, a facial silicone pad for contacting the wearer's face, and a retaining wall connecting the frame cover and the facial silicone pad; the forehead silicone pad is detachably connected to the forehead support, comprising a forehead glue layer for fitting the wearer's forehead, a forehead pad for abutting the forehead support, and a supporting portion for supporting the forehead glue layer and the forehead pad, the forehead pad is provided with a docking portion on a side away from the forehead glue layer, and the forehead glue layer and the forehead pad are both provided with an arc-shaped connecting portion in the middle position.

[0006] As a further improvement, a plurality of embedded plates are intermittently arranged along the edge of the frame body, and a plurality of clamping blocks are arranged between adjacent embedded plates.

[0007] As a further improvement, headband holes for connecting a headband are arranged on both sides of the forehead support, and a plurality of docking grooves for docking with the forehead silicone pad are opened on the forehead support.

[0008] As a further improvement, the frame cover is provided with an annular groove for clamping the frame body, and the annular groove is provided with two sections, one section is a first embedding groove covering the frame body, and the other section is a second embedding groove covering the embedded plate.

[0009] As a further improvement, the annular groove is provided with a positioning groove adapted thereto at a position corresponding to the card block, and the frame cover is provided with an adapted inlay groove at a position corresponding to the connecting bracket and the headband hanger.

[0010] As a further improvement, the facial silicone pad is provided with second protrusions on both sides of the nose bridge, and with first protrusions on both sides of the cheeks, a nose bridge groove for fitting the nose bridge is provided between the two second protrusions, and a chin pad for fitting on the chin is provided between the two first protrusions.

[0011] As a further improvement, the angle formed between the nose bridge grooves is defined as A, and the range of A is 80° to 110°.

[0012] As a further improvement, the angle formed between the mandibular pads is defined as B, and the range of B is 100° to 120°.

[0013] As a further improvement, the bent pipe includes a ventilator connecting pipe for connecting to a ventilator air supply pipe, an anti-suffocation valve is embedded in the ventilator connecting pipe, an adapter is connected between the ventilator connecting pipe and the frame, and an exhaust hole for carbon dioxide discharge is provided on the adapter.

[0014] As a further improvement, the hook is provided with a hook for connecting to the headband hanger, and the hook is provided with a band through hole for connecting the headband.

[0015] The beneficial effects of the utility model are:

[0016] The utility model adjusts the connection mode between the frame and the mask pad so that the mask pad and the frame are fitted on three sides, thereby improving the air tightness of the connection between the mask pad and the frame, preventing gas from leaking out from between the mask pad and the frame during oxygen supply, and the connecting bracket fits the curvature of the nose bridge more closely. The cooperation between the headband hanger and the hook makes the wearing mode of the ventilation mask more convenient, and the connection relationship between the frame and the mask pad is fixed by the cooperation of the card block and the positioning groove, thereby improving the air tightness of the connection between the two. Moreover, by observing the cooperation between the card block and the positioning groove, it can be used as one of the standards for checking whether there is air leakage between the frame and the mask pad. The mask pad has special supporting structures at the bridge of the nose and the cheek, and cooperates with the bridge of the nose groove and the mandibular pad to make the mask pad fit the human face more closely, so that the mask pad forms an integrated linkage structure. When air is supplied, the structures at the bridge of the nose and the cheeks are squeezed by pressure, which props up the entire ventilation mask and makes it fit more closely to the human face to prevent air leakage. When air is deflated, the special structure slowly contracts to avoid pressure sores on the face and improve the comfort of the wearer. By providing an arc-shaped connecting part on the forehead silicone pad, the forehead silicone pad is easier to bend and fits more closely to the wearer's forehead to reduce the occurrence of pressure sores. An anti-suffocation valve is provided on the bent pipe to cover the exhaust hole during air supply to prevent gas leakage, effectively controlling the dead space of the ventilation mask within the specified range. For wearers with special needs, additional interfaces are provided on the frame body, which can be used to connect other medical equipment to increase the amount of oxygen inhaled by the wearer, and the structure of the forehead bracket is adjusted to improve the wearing comfort of the wearer.
