Description

Passive humidification laryngeal mask

Technical Field

The utility model relates to a passive type humidification laryngeal mask, in particular to a passive type humidification laryngeal mask with filtering and dustproof effects.

Background

Under normal conditions, the respiratory tract has warming, humidifying and filtering effects on the inhaled gas. After tracheotomy and laryngeal resection, gas is inhaled through the cervical incision, and normal breathing pattern changes. The warming, humidifying and filtering effects of the upper airway on the gas disappear, so that the airway is dry, secretion is sticky and difficult to discharge, sputum scab is formed, the airway is blocked, and even lung infection occurs.

The traditional non-mechanical ventilation autogenous cutting patient or the complete laryngeal resecter does not have a special dust cover, the neck air vent is covered by a piece of gauze or a piece of mask, the air moisturizing effect cannot be achieved, and the local incision condition is not easy to observe; although the air can be filtered by the artificial nose for the autogenous cutting patient, the artificial nose is only suitable for the patient without sputum or with less sputum, the airway is easy to be blocked when the sputum is excessive, the patient is polluted by the sputum and must be replaced, and the artificial nose is disposable and cannot be used repeatedly, so that the cost is high.

Based on the disease mechanism and the problems existing in the prior art, the utility model designs the passive wet laryngeal mask with better use effect and filtering and dustproof effects.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model aims to provide the passive humidifying laryngeal mask with the filtering and dustproof effects, which has reasonable structural design, has the functions of dust prevention, moisture preservation, foreign matter inhalation prevention and air filtration, can adjust the fixing belt of the filtering mask according to the needs, is not only suitable for autogenous cutting patients, but also suitable for all-laryngeal cutting patients, and is convenient and reliable to use and strong in practicability.

In order to achieve the above object, the present utility model is realized by the following technical scheme: the passive humidification laryngeal mask with the filtering and dustproof effects comprises a transparent mask, oxygen supply holes, a grid type cover and fixing belts, wherein the grid type cover is arranged in the middle of the transparent mask, a filtering membrane is covered on the grid type cover, the fixing belts are connected to the two ends of the transparent mask, and the oxygen supply holes are formed in the two sides above the grid type cover; the bottom of the grid cover is hinged on the transparent cover, and the upper end of the grid cover is buckled on a bayonet on the transparent cover.

Preferably, the transparent cover is a plastic transparent cover.

Preferably, a filtering membrane is embedded in the grid type cover.

Preferably, the oxygen supply holes are holes for plugging oxygen pipes.

Preferably, the fixing strap is a fixing strap with a length adjustable magic tape.

The beneficial effects of the utility model are:

1. the plastic cover can prevent the moisture of the exhaled air from evaporating, and relative air humidity is formed in the cover; the grids on the plastic cover are beneficial to ventilation and prevent carbon dioxide retention;

2. the grid in the center of the plastic cover can be opened to suck phlegm, so that the plastic cover is suitable for patients with excessive phlegm;

3. the filter membrane is embedded in the grid. The filtering membrane uses a water absorbing material and a hydrophilic compound, retains moisture carried by a patient during exhalation, and plays a role in humidifying inhaled gas by using the exhaled moisture and heat during inhalation; the filtering membrane can be replaced at any time due to sputum pollution, is low in cost, clean and sanitary, and reduces the probability of respiratory tract infection;

4. the oxygen supply holes are respectively arranged at the left and the right, so that oxygen pipes in different directions can be conveniently connected;

5. the passive humidification laryngeal mask can effectively reduce the spreading of pathogen-containing aerosol in the air, reduce the transmission of respiratory infectious diseases and reduce the occupational exposure risk of medical staff while protecting the open airway of a patient;

6. the whole laryngeal mask can be repeatedly used after being wiped by 75% alcohol or soaked and sterilized by 500mg/L available chlorine disinfectant, and is economical and sanitary.

Drawings

The utility model is described in detail below with reference to the drawings and the detailed description;

fig. 1 is a schematic structural diagram of the present utility model.

Detailed Description
