Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 2, an anti-asphyxia respiratory mask according to a preferred embodiment of the present invention includes: the air inlet and outlet assembly 10, the mask body 20 and the mask support frame 30.

The air inlet and outlet assembly 10 is provided with an air inlet port 11, an air inlet conduit 12, an anti-asphyxia port 13 and a breather valve 14, wherein the air inlet port 11 is fixedly sleeved at the outer end of the air inlet conduit 12 through two lock catches 111, such as elastic clamps. The air inlet conduit 12 is in the shape of an elbow and can pass through the mask support frame 30 and be fixedly arranged on the mask body 20. The anti-suffocation port 13 is arranged on the side wall of the air inlet conduit 12, and when the breathing machine fails or the power failure fails to ventilate the patient, the anti-suffocation port 13 can enable the breathing mask to be communicated with the outside air, so that the suffocation phenomenon of the patient is avoided. The breather valve 14 is composed of a clamping hole 141 and a valve plate 142, the clamping hole 141 is also arranged on the side wall of the air inlet duct 12 and is at the same side with the anti-suffocation port 13, one end of the valve plate 142 is clamped and fixed in the clamping hole 141, the other end can freely swing in the air inlet duct 12, and in addition, the diameter of the valve plate 142 is larger than the outer diameter of the anti-suffocation port 13. When the respirator works normally, the continuous airflow pressure existing in the air inlet conduit 12 acts on the valve plate 142 to enable the valve plate to swing upwards and completely seal the anti-asphyxia port 13, so that the normal air inlet pressure in the respirator is kept.

When the breathing machine breaks down or the power failure can not ventilate to the patient, no airflow pressure exists in the air inlet pipeline, the valve plate 142 can fall downwards under the action of gravity, the anti-suffocation port 13 is opened, the patient can communicate with the outside through the anti-suffocation port 13 to maintain breathing, and before medical staff finds and handles the patient, the breathing safety of the patient can be guaranteed.

In the utility model, a plurality of small holes are intensively and uniformly distributed in the middle of the mask body 20, as shown in fig. 1, the small holes are used for discharging the gas exhaled by the patient to the outside, and the normal ventilation pressure in the mask can be kept, so that the gas leakage phenomenon of the mask can not occur.

Referring to fig. 1 to 2, the mask body 20 is made of a mask sealing gasket 22, and the mask sealing gasket 22 is made of a soft rubber material, such as silica gel, so that the mask body can provide a good fit feeling to the face of the patient, thereby improving the comfort of use, reducing the air leakage of the mask, ensuring the air pressure in the mask, and providing sufficient oxygen input for the patient. In the outside of face guard body 20, closely the laminating installs face guard support frame 30, and the both sides of face guard support frame 30 respectively are provided with a collection mouth 31 that can UNICOM's outside air and face guard inner space, and in the respirator use, this collection mouth 31 can conveniently connect the pressure-measuring pipe of pressure monitor for pressure in the monitoring patient's face guard also can connect the humidifying pipe, to the humidification in the face guard, with the dry humidity of mediating the interior gas of face guard. This gather mouthful 31 one end towards the outside air and be equipped with the knot stopper 311, when need not use and gather mouthful 31, can fill in the collection mouthful 31 with knot stopper 311 in, the oxygen that admits air in the guarantee face guard can not pass through and gathers mouthful gas leakage.

Further, the mask support frame 30 is provided with first headgear interfaces 32 on both sides thereof, and the first headgear interfaces 32 are used to secure the mask to the head of a patient when the respiratory mask is being used on the patient.

Further, the middle part of the mask supporting frame 30 is provided with a through hole 33, the through hole 33 can be communicated with the air outlet holes 21, and the inner diameter of the through hole 33 is larger than the outer diameter of the air outlet holes 21, so that the mask supporting frame 30 can not block the air circulation of the air outlet holes 21 and the outside.

Furthermore, the part of face guard support frame 30 and patient's forehead contact is supporting seat 34, supporting seat 34 and face guard support frame 30 integrated into one piece, supporting seat 34 towards patient's facial one side joint have forehead pad 341, forehead pad 341 direct contact patient's forehead, because forehead pad 341 is the software material, like silica gel etc. therefore the patient feels more comfortable, safety in use. Two ends of the support base 34 are provided with two headband interfaces 342 for binding the support base 34 and the head of the patient so as to fix the breathing mask stably.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
