Background
In the respiratory diagnosis and treatment process, the noninvasive ventilator has the advantages of no need of establishing an artificial airway, simplicity in operation and the like, can reduce pain of patients and infection risk, and avoids damage caused by tracheal intubation, so that the noninvasive ventilator is widely applied. However, during use, gas always enters the stomach of a patient through mouth to cause gastrectasia and abdominal distension, especially for old patients, the old patients often breathe through mouth opening, so that more gas entering the lung enters the stomach and abdomen, uncomfortable symptoms of the gastrectasia and abdominal distension occur for the patient, certain pressure is caused to respiratory diaphragm, and dyspnea is increased. Some elderly patients suffer from the weakness of the lingual muscle, and in a supine position, the tongue tends to fall back under the action of gravity to block the airway, which can lead to dyspnea or even choking. In addition, the mask of the noninvasive ventilator needs to be tightly buckled on the face of a patient to cover the mouth and nose parts, so that complications such as pressure sores are easily caused.
Disclosure of utility model
In view of the above problems, the present application aims to provide a mouthpiece for a noninvasive ventilator mask, which is used in combination with a noninvasive ventilator mask, and by means of which the mouth of a patient is effectively blocked, so that the gas entering the stomach and abdomen through the mouth is as little as possible, and the occurrence of symptoms such as abdominal distension and gastrectasia is avoided, and furthermore, the present application aims to provide a mouthpiece for a noninvasive ventilator mask, which is used in combination with a noninvasive ventilator mask, and which reduces the pressure of the noninvasive ventilator mask to the face of the patient and reduces the occurrence of pressure sores.
The application relates to a mouthpiece for a noninvasive ventilator mask, which comprises a base plate, an insert, a gasket and a bolt;
The base plate is made of plastic, is formed into an oval shape, and is provided with a through hole in the middle;
The insert is used for being inserted into the oral cavity of a subject, and is made of plastic and comprises a linear main body part, wherein the cross section of the main body part is elliptical;
The bolt is inserted into the threaded hole of the insert after passing through the through hole of the base plate, thereby detachably fixing the insert at the rear side of the base plate;
The gasket is made of medical silica gel or medical dressing and comprises a triangular outer ring and an elliptical inner ring, wherein the inner ring and the outer ring are connected together through a connecting part, the gasket is sleeved on the periphery of the main body part of the insert through the inner ring, and the outer ring of the gasket is arranged between the noninvasive ventilator mask and the face of a subject.
Preferably, the rear end of the insert forms a downwardly curved arc for insertion into the rear side of the tongue of the subject.
Preferably, the rear side of the base plate is formed with an oval recess in which the front end of the insert is insertedly mounted.
Preferably, the upper and lower sides of the front portion of the insert are respectively formed with grooves to accommodate the teeth of the subject.
The mouth piece for the noninvasive respirator mask provided by the application can effectively prevent air from entering the stomach and the abdomen of a patient through the oral cavity by plugging the oral cavity through the insert, can effectively reduce the pressure damage of the edge of the mask to the face of the patient through the gasket, and can effectively prevent the occurrence of tongue falling through the bending part formed at the rear end of the insert and inserted into the rear side of the tongue.

Detailed Description
The mouthpiece for a noninvasive ventilator mask of the present application will be described in detail with reference to the accompanying drawings.
The application relates to a mouthpiece for a noninvasive respirator mask, which comprises a base plate 1, an insert 2, a gasket 3 and a bolt 4.
The base plate 1 is made of plastic, formed in an elliptical shape, and formed with a through hole 11 in the middle.
The insert 2 is for insertion into the oral cavity of a subject and is made of plastic and comprises a rectilinear main body portion having an oval cross section, and a threaded hole 22 is formed in the front end face of the insert 2.
The bolts 4 are inserted into the screw holes 22 of the insert 2 after passing through the through holes 11 of the base plate 1, thereby detachably fixing the insert 2 to the rear side of the base plate 1.
The gasket 3 is made of medical silica gel or medical dressing and comprises a triangular outer ring 32 and an elliptical inner ring 31, wherein the inner ring 31 and the outer ring 32 are connected together through a connecting part 33, the gasket 3 is sleeved on the periphery of the main body part of the insert 2 through the inner ring 31, and the outer ring 32 of the gasket 3 is used for being arranged between the noninvasive ventilator mask and the face of a subject.
In one embodiment, the rear end of the insert 2 forms a downwardly curved arc 23, the arc 23 being intended to be inserted into the rear side of the tongue of a subject, such a configuration being commonly used in the oropharyngeal airway, in which case nasal ventilation is desired, and thus no hollow configuration of the oropharyngeal airway is employed.
An elliptical recess 12 is formed on the rear side of the base plate 1, and the front end of the insert 2 is insertedly fitted into the recess 12.
The upper and lower sides of the front portion of the insert 2 are respectively formed with grooves 21 to accommodate the teeth of the subject.
When the noninvasive ventilator mask is used, the insert of the mouthpiece for the noninvasive ventilator mask is firstly inserted into a patient's mouth, then the outer ring of the gasket is arranged on the face of the patient in a fitting mode, then the noninvasive ventilator mask is worn on the face of the patient to cover the mouth and the nose of the patient, at the moment, the outer ring of the gasket of the mouthpiece for the noninvasive ventilator mask is positioned between the edge part of the mask and the face of the patient, so that pressure sores can be effectively prevented, and the rest parts of the mouthpiece for the noninvasive ventilator mask are positioned inside the mask. The insert can effectively prevent air in the mask from entering the stomach and the abdomen of a patient through the oral cavity, and avoid the occurrence of gastrectasia and abdominal distension. If the patient is with the glossomyasthenia, the insert shown in fig. 7 and 8 can be selected, and the bending part of the insert is inserted into the back side of the tongue of the patient, so that the occurrence of glossoptosis can be effectively avoided.
