Embodiment 1

[0019] See image 3 , Figure 4 , the improved ventilator mouth-nose mask that the present invention provides, comprises the mask 2 that is provided with sealing skirt 3 and air intake pipe 1, is located at the soft sheet 4 that covers people's mouth on described mask 2, and the soft sheet 4 of described soft sheet 4 A concave portion 401 is provided on the lateral side.

[0020] Further, the concave portion 401 is provided on the upper side of the soft sheet 4 .

[0021] Further, the soft sheet 4 is integrated with the sealing skirt 3 , or the soft sheet 4 can also be arranged at the edge of the opening of the mask 1 (not shown), and is not integrated with the sealing skirt 3 .

[0022] When the patient wears the present invention for non-invasive ventilation treatment, the ventilator provides a pressure greater than atmospheric pressure, and the soft sheet 4 is close to the upper and lower lips a, b, so that the patient can only breathe through the nose.

[0023] Since th...

Embodiment 2

[0025] The present invention also can be provided with outlet channel at soft sheet 4, as Figure 5 As shown, the air outlet channel can be a hole 5; as Figure 6 As shown, the air outlet channel can also be a cutout 6 .

[0026] When the pressure in the oral cavity is greater than the pressure in the mask cavity, the lips can push away the soft sheet 4, so that the gas in the oral cavity can be exhaled through the air outlet channel.

Abstract

The invention discloses an improved respirator mouth-nose mask which comprises a mask body provided with a sealing skirt edge and a soft thin sheet arranged on the mask body and used for covering the mouth of a person; a concave part is arranged on the transverse side edge of the soft thin sheet, or an air outlet channel is formed in the soft thin sheet. The invention can solve the problem of breathing under the condition that the soft sheet covers the mouth.

Description

technical field [0001] The invention belongs to medical appliances, and in particular relates to an improved ventilator mouth and nose mask. Background technique [0002] Ventilator-assisted ventilation is widely used in clinical practice. Non-invasive ventilators use mask ventilation. Patients with sleep apnea and COPD are treated with non-invasive positive pressure ventilation in hospitals or at home. The mask covers the patient's nasal cavity or oral cavity or completely covers the nasal cavity. In order to solve the problem of dry mouth and throat caused by some patients opening their mouths when using a ventilator, the inventor proposed a mouth-nasal mask for a ventilator that uses a soft sheet to cover the mouth (see Chinese patent document CN101780300A), such as figure 1 , figure 2 As shown, this mouth and nose mask includes a mask 2 provided with a sealing skirt 3 and an air intake pipe 1, and a soft sheet 4 arranged on the mask 2 to cover the mouth. The soft sheet...
