Description

A new Y-shaped nasal mask for non-invasive ventilation

technical field

The utility model relates to the technical field of medical devices, in particular to a novel Y-shaped nasal mask for non-invasive ventilation.

Background technique

Non-invasive ventilation generally refers to a mechanical ventilation method in which the ventilator is connected to the patient through a nasal or mouth-nose mask, and the non-invasive ventilator provides positive pressure support to complete ventilation assistance. Non-invasive ventilation is clinically used to treat sleep apnea syndrome and related diseases. It is suitable for patients with mild to moderate respiratory failure, especially type II respiratory failure, who have no indications for emergency intubation and whose vital signs are relatively stable. It is used for early intervention of respiratory failure and auxiliary weaning. The more common clinical applications include acute COPD, stable COPD, cardiogenic pulmonary edema, acute exacerbation of bronchial asthma, and sleep apnea syndrome and other diseases.

Non-invasive breathing has the characteristics of less pain, flexible application, and intermittent or continuous application. Especially for patients with chronic obstructive pulmonary disease, the application effect is better, which can shorten the time of invasive ventilation, reduce complications, improve survival rate, and reduce medical expenses. Compared with invasive ventilation, non-invasive ventilation has almost no airway damage to patients, is easy to operate, has high patient comfort, and is more acceptable. As an important treatment method for the treatment of respiratory system dysfunction, non-invasive breathing is widely used in departments such as respiratory department, geriatric department and ICU. With the increase in the incidence of related indications and the needs of the condition, some patients need to use non-invasive ventilators for a long time, and then gradually make non-invasive ventilators home.

Using a nasal mask is a method of non-invasive ventilation. In order to ensure the airtightness of the breathing circuit, the non-invasive ventilator needs to fit the nasal mask tightly to the face and press the nose and face with a certain pressure. The traditional nasal mask is affixed to the patient's face with a plastic gasket, and then fixed with a fixing belt to close the ventilation space;

The disadvantages of this technique are:

(1) Since the facial skin is usually sensitive and there is less subcutaneous fat in the nose, this method oppresses the patient's facial skin for a long time, which may easily cause local blood flow in the face to be blocked, which will seriously cause skin and subcutaneous tissue ischemia, continuous ischemia, Hypoxia, malnutrition and even pressure sores make patients unable to use non-invasive breathing for a long time, which affects the comfort and compliance of patients using non-invasive ventilator treatment;

(2) It is not reliable to simply use the fixing belt to fix it. The patient will turn over or move unconsciously during deep sleep, which may cause the position of the nasal mask and the fixing belt to change, causing the nasal mask to shift or even leak air, resulting in non-invasive ventilation. fail;

(3) When the nasal mask is used, the patient may unconsciously open the mouth during sleep, and it is easy to leak air from the mouth, which significantly weakens the therapeutic effect of non-invasive ventilation. At present, some nasal masks are equipped with a mandibular fixing belt during use, so that the patient cannot open his mouth to breathe, but at the same time, the patient cannot move the mandible, and the comfort is extremely poor.

Instructions:

(1) First, place the double-chamber ventilation branch tubes at the front end of the Y-shaped ventilation tube 100 into the nasal cavities on both sides of the user, observe the scale line 108 and place the nasal mask at an appropriate depth, so that the ventilation at the front end of the Y-shaped ventilation tube 100 The mouth and the first air bag 102 are placed in the user's nasopharynx, and the second air bag 103 is placed in the user's nasal cavity, and then the first air bag 102 and the second air bag are supplied to the first air bag 102 and the second air bag by the first air bag inflation valve 106 and the second air bag inflation valve 107 respectively. Inject appropriate amount of air into 103 to expand the two pairs of airbags;

Monitor the pressure of the airbag by testing the pressure of the airbag inflation indicator ball on the inflation valve, so that the two pairs of airbags are in a proper filling state;

After the first airbag 102 is inflated, it can push away the base of the user's tongue and surrounding soft tissues, exposing the perineum to open the airway, effectively solving the problem of upper airway obstruction;

After the two pairs of airbags are inflated, the nasal cavity space outside the Y-shaped ventilation tube 100 can be sealed to avoid air leakage of the nasal mask, and at the same time, the position of the nasal mask can be fixed;

(2) Then, wrap the fixing belt 2 around the user's head and neck, put the buckle end 201 of the fixing belt on the buckle ring 109 of the fixing belt, tighten the fixing belt at an appropriate tension, and fix the nasal mask at a proper position;

(4) Finally, use a sterile applicator 3 to stick on the user's mouth to seal the user's mouth to avoid ineffective ventilation;

(5) When removing the nasal mask, the fixing strap needs to be removed first, and then the air in the first airbag 102 and the second airbag 103 should be evacuated through the first airbag inflation valve 106 and the second airbag inflation valve 107, so that the two pairs of airbags collapse, and finally remove the nasal mask. At the same time, it is necessary to remove the applicator pasted on the user's mouth.

A new Y-shaped nasal mask for non-invasive ventilation in this embodiment solves the problem of the traditional non-invasive ventilation that the nasal mask presses the skin and makes the patient feel uncomfortable, and is easy to shift and dislocate, resulting in poor sealing. The two pairs of airbags can be inflated and fixed in the patient's nasal cavity during use. The first airbag 102 at the front end is placed in the patient's nasopharynx when in use. After inflating, it can push the base of the tongue and soft tissues away, exposing the epipharynx and other structures, and opening the airway. It effectively solves the problem of upper airway obstruction. At the same time, it can effectively seal the nasal cavity space outside the pipeline after the nasal mask is placed, avoiding air leakage of the nasal mask, and can also fix the position of the nasal mask. The second air bag 103 at the rear end plays a double sealing and fixing role to ensure ventilation efficiency. The elastic fixing strap and buckle design can prevent the nasal mask from shifting and falling off caused by the user's unconscious movement during sleep.

The utility model is different from the previous nasal mask design, does not oppress the user's facial skin, can protect the user's facial skin, and will not cause redness, swelling, pressure sores and the like. When the nasal mask is used, the matching sterile applicator can seal the patient's mouth to prevent gas from leaking from the mouth during non-invasive ventilation, causing the problem that the actual ventilation cannot reach the preset tidal volume of the ventilator. And the middle part of the application covering the lips is designed as a non-adhesive dressing, which can protect the user's lip skin and improve the user's comfort and acceptance.

Apparently, the embodiments described above are only preferred specific embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
