Abstract
The utility model discloses an improved respirator oronasal mask which comprises a mask with a sealing skirt edge and a soft sheet arranged on the mask and used for covering a human mouth, wherein a concave part is arranged on the transverse side edge of the soft sheet, or an air outlet channel is arranged on the soft sheet. The utility model can solve the problem of exhalation under the condition that the soft sheet covers the mouth.
Description
Technical Field
The utility model belongs to medical appliances, and particularly relates to an improved respirator oronasal mask.
Background
The ventilator assisted ventilation is widely used in clinic, the noninvasive ventilator adopts mask ventilation, patients with sleep apnea, COPD and the like use noninvasive positive pressure ventilation treatment in hospitals or families, and the nasal cavity or the oral cavity of the patients are covered by the mask or the oral and nasal cavities are covered by the mask. In order to solve the problem that the mouth and throat of some patients are dry due to the open mouth when using the respirator, the utility model discloses a mouth and throat mask for the respirator (see Chinese patent document CN 101780300A) which utilizes a soft sheet to cover the mouth of the patient is proposed, as shown in figures 1 and 2, the mouth and nose mask comprises a face mask 2 provided with a sealing skirt edge 3 and an air inlet pipe 1 and a soft sheet 4 arranged on the face mask 2 and used for covering the mouth of the patient, the soft sheet 4 and the sealing skirt edge 3 are integrated, when in noninvasive ventilation treatment, the respirator provides pressure higher than atmospheric pressure, and the soft sheet 4 is tightly attached to the upper lip a and the lower lip b, so that the patient can only breathe through the nose. The mask is already applied to clinic and achieves certain curative effect. However, the mask still has the problem that the patient response differs clinically, and some patients are better in use effect, and some patients are intolerant, because many patients are old patients, can't describe the reason of intolerance, bring the confusion for the utility model people, through utility model people's many years's thinking, think that the reason may be that the mask exhales difficulty and foreign body sensation to improve the mask.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an improved respirator oronasal mask to solve the problem of exhaling under the condition that a soft sheet covers the mouth.
The technical scheme for realizing the purpose of the utility model is as follows: the improved respirator nose mask comprises a mask body with a sealing skirt edge and a soft sheet arranged on the mask body and covering the mouth of a person, wherein a concave part is arranged on the transverse side edge of the soft sheet.
The concave part is arranged on the upper side edge of the soft sheet.
The other technical scheme for realizing the aim of the utility model is as follows: the improved respirator nose and mouth mask comprises a mask body with a sealing skirt edge and a soft sheet arranged on the mask body and covering the mouth of a person, wherein an air outlet channel is arranged on the soft sheet.
The air outlet channel is a hole or a notch.
The flexible sheet is integral with the sealing skirt.
The present invention is derived from long-term clinical observations and studies of the problem of intolerance of utility model people to some patients. Through repeated thinking of the reason, the fact that most of the mouth of a patient is covered by the soft thin sheet is found, under the repeated action of positive pressure of a breathing machine, air between the thin sheet and the skin of the mouth of the patient is discharged, a small amount of liquid can be discharged from the skin, the skin is fully contacted with the soft thin sheet, under the positive pressure of the breathing machine, a large friction force exists between the thin sheet and the skin of the mouth of the patient, the force prevents the mouth of the patient from being opened, the patient does not open the mouth, obviously, when the diameter of the air outlet channel is far smaller than that of the nasal cavity channel, air entering from the nasal cavity channel is more than air entering from the oral cavity channel during inhalation, the soft palate is pushed to move towards the tongue heel, the oral cavity channel is blocked, the patient cannot inhale, the air is warmed and humidified through the nose, and the mouth cannot be dried.
Some patients do not tolerate, an important reason is that the pressure of a breathing machine cannot support the soft palate to be tightly attached to the tongue heel, the mouth opening at the soft palate is larger than the opening of the nasal cavity passage, when the breathing machine breathes out, the lung contracts, and higher-pressure gas enters the mouth more than the nasal cavity passage. The problem that the user can exhale under the condition that the mouth is covered by the soft sheet is well solved.
Through clinical application, according to statistics on the use conditions of 20 patients, 18 patients show that the tolerance is obviously improved, the effective rate is 90%, and an obvious effect is achieved.
The utility model is further illustrated with reference to the following figures and examples.

Detailed Description
Example 1
Referring to fig. 3 and 4, the improved respirator oronasal mask provided by the utility model comprises a face mask 2 provided with a sealing skirt 3 and an air inlet pipe 1, and a soft sheet 4 arranged on the face mask 2 and covering the mouth of a person, wherein the transverse side edge of the soft sheet 4 is provided with a concave part 401.
Further, the concave portion 401 is provided on the upper side of the soft sheet 4.
Further, the flexible sheet 4 is integrated with the sealing skirt 3, or the flexible sheet 4 may be provided at the edge of the opening of the mask 1 (not shown) without being integrated with the sealing skirt 3.
When the patient wears the utility model to do non-invasive ventilation treatment, the respirator provides pressure which is larger than atmospheric pressure, and the soft thin sheet 4 is tightly attached to the upper lip a and the lower lip b, so that the patient can only breathe by using the nose.
Since the concave part 401 is arranged on the soft sheet 4, the area of the soft sheet 4 is reduced, the covering area and the friction force to the upper lip a are also reduced, the firm degree of the sealing of the soft sheet to the lips is reduced, and as long as the oral pressure is greater than the pressure of the mask cavity, the oral pressure can easily push the lips and the soft sheet 4 away, and the air is discharged from the concave part 401.
Example 2
The present invention may also be provided with air outlet channels in the flexible sheet 4, as shown in fig. 5, the air outlet channels may be holes 5; as shown in fig. 6, the air outlet channel may also be a slit 6.
When the pressure of the mouth cavity is higher than that of the mask cavity, the lips can push the soft sheet 4 away, so that the gas in the mouth cavity is exhaled through the air outlet channel.
