Abstract
Description
Technical Field
[0001] The present application relates to a medical device, and more particularly to a mouthpiece for a non-invasive ventilator mask. Background Art
[0002] During the process of respiratory diagnosis and treatment, due to the advantages of non-invasive ventilators such as not requiring the establishment of an artificial airway and simple operation, it can reduce the pain of patients and the risk of infection, and avoid the damage caused by tracheal intubation. Therefore, it has been widely used. However, during use, gas often enters the patient's stomach through the mouth, causing abdominal distension; especially for elderly patients, they often breathe through their mouths during use, allowing more gas that should enter the lungs to enter the stomach and abdomen, resulting in discomfort symptoms such as abdominal distension and flatulence in the patient, and also causing a certain pressure on the respiratory diaphragm, increasing the difficulty of breathing. There is also a part of elderly patients with weak tongue muscles. In the supine position, due to the action of gravity, the tongue is prone to fall backward and block the airway, which can lead to difficulty in breathing or even suffocation. In addition, the mask of the non-invasive ventilator needs to be tightly buckled on the patient's face, covering the mouth and nose, so it is easy to cause complications such as pressure sores. Utility Model Content
[0003] In view of the above problems, the present application aims to propose a mouthpiece for a non-invasive ventilator mask, which is used in cooperation with the non-invasive ventilator mask. By means of the mouthpiece, the patient's oral cavity can be effectively blocked, so that the gas entering the stomach and abdomen through the oral cavity is as little as possible, avoiding the appearance of symptoms such as abdominal distension and flatulence; in addition, the present application also aims to propose a mouthpiece for a non-invasive ventilator mask, which is used in cooperation with the non-invasive ventilator mask to reduce the pressure of the non-invasive ventilator mask on the patient's face and reduce the occurrence of pressure sores.
[0004] The mouthpiece for a non-invasive ventilator mask of the present application includes: a base plate, an insert, a gasket, and a bolt;
[0005] The base plate is made of plastic, formed in an oval shape, and has a through hole formed in the middle;
[0006] The insert is used to be inserted into the oral cavity of the subject. The insert is made of plastic and includes a linear main body; the cross-section of the main body is oval; a threaded hole is formed on the front end surface of the insert;
[0007] The bolt passes through the through hole of the base plate and is inserted into the threaded hole of the insert, whereby the insert can be detachably fixed to the rear side of the base plate; <�
[0008] The gasket is made of medical silicone or medical dressing, and includes a triangular outer ring and an oval inner ring; the inner ring and the outer ring are connected together by a connecting portion; the gasket is sleeved on the outer periphery of the main body of the insert through its inner ring; the outer ring of the gasket is used to be arranged between the non-invasive ventilator mask and the face of the subject.
[0009] Preferably, the rear end of the insert forms an arc-shaped portion that bends downward, and the arc-shaped portion is used to insert into the rear side of the tongue of the subject.
[0010] Preferably, an oval recess is formed at the rear side of the substrate, and the front end of the insert is inserted and installed in the recess.
[0011] Preferably, grooves are respectively formed on the upper side and the lower side of the front portion of the insert to accommodate the teeth of the subject.
[0012] The mouthpiece for a non-invasive ventilator mask of the present application blocks the oral cavity through its insert, effectively preventing air from entering the patient's stomach and abdomen through the oral cavity; the mouthpiece for a non-invasive ventilator mask of the present application, through its gasket, can effectively reduce the pressure damage of the mask edge to the patient's face; the mouthpiece for a non-invasive ventilator mask of the present application, through the formation of a bent portion at the rear end of its insert and inserting into the rear side of the tongue, can effectively prevent the occurrence of posterior tongue prolapse.

[0022] The mouthpiece for a non-invasive ventilator mask of the present application will be described in detail below with reference to the accompanying drawings.
[0023] The mouthpiece for a non-invasive ventilator mask of the present application includes: a substrate 1, an insert 2, a gasket 3, and a bolt 4.
[0024] The substrate 1 is made of plastic, formed in an oval shape, and a through hole 11 is formed in the middle.
[0025] The insert 2 is for inserting into the oral cavity of a subject. The insert is made of plastic and includes a linear main body portion; the cross-section of the main body portion is oval; a threaded hole 22 is formed on the front end face of the insert 2.
[0026] The bolt 4 passes through the through hole 11 of the substrate 1 and then inserts into the threaded hole 22 of the insert 2, thereby detachably fixing the insert 2 at the rear side of the substrate 1.
[0027] The gasket 3 is made of medical silicone or medical dressing and includes a triangular outer ring 32 and an oval inner ring 31; the inner ring 31 and the outer ring 32 are connected together by a connecting portion 33; the gasket 3 is sleeved on the outer periphery of the main body portion of the insert 2 through its inner ring 31; the outer ring 32 of the gasket 3 is for being arranged between the non-invasive ventilator mask and the face of the subject.
[0028] In one embodiment, the rear end of the insert 2 forms a downwardly curved arc portion 23, and the arc portion 23 is for inserting behind the tongue of the subject. This structure is commonly used in oropharyngeal airways. In the present application, nasal ventilation is expected, so the hollow structure of the oropharyngeal airway is not adopted.
[0029] An oval recessed portion 12 is formed at the rear side of the substrate 1, and the front end of the insert 2 is inserted and installed in the recessed portion 12.
[0030] Grooves 21 are respectively formed on the upper side and the lower side of the front portion of the insert 2 to accommodate the teeth of the subject.
[0031] When in use, first insert the insert of the mouthpiece for the non-invasive ventilator mask of the present application into the patient's mouth, and then arrange the outer ring of the gasket snugly on the patient's face; then put the non-invasive ventilator mask on the patient's face to cover the patient's mouth and nose. At this time, the outer ring of the gasket of the mouthpiece for the non-invasive ventilator mask of the present application is located between the edge of the mask and the patient's face, thereby effectively preventing the occurrence of pressure sores; the remaining components of the mouthpiece for the non-invasive ventilator mask of the present application are all located inside the mask. The insert can effectively prevent the air in the mask from entering the patient's stomach and abdomen through the oral cavity, avoiding the occurrence of gastric distension and abdominal distension. For patients with weak tongue muscles, the insert shown in Figure 7 and 8 can be selected, and the curved part of the insert is inserted behind the patient's tongue, so as to effectively avoid the occurrence of tongue posterior prolapse.
