Examples

As shown in fig. 1 to 3, in an embodiment of the multifunctional noninvasive ventilator mask provided by the present invention, the multifunctional noninvasive ventilator mask includes a mask body 1, a forehead part 2 and a headband 3; the edge of the mask body 1 is coated by at least two inflatable air bags; the forehead part 2 is connected with the mask body 1; two head bands 3 are respectively connected with the mask body 1 and the forehead part 2 so as to detachably fix the mask body 1 and the forehead part 2 on the head of a human body.

Specifically, the air bag of the mask body 1 is made of soft silica gel, a partition is arranged in the middle of the air bag to form two sub air bags, namely, the partition divides the air bag into an upper part and a lower part, the upper part and the lower part are respectively provided with an inflation inlet, and a one-way valve is arranged in the inflation inlet to enable the upper sub air bag and the lower sub air bag to be inflated independently. The arrangement can adjust the filling degree of the upper sub-air bags according to the bone shape characteristics of the face of a patient, and adjust the filling degree of the lower sub-air bags according to the activity degree of the lower jaw of the patient, so that the mask body 1 is more attached to the face of the patient, and the gap between the mask body 1 and the face is reduced to reduce air leakage; the worker does not have to adjust the headband 3 to secure it to the head, enabling the patient to have greater comfort during use.

It is understood that the present embodiment specifically exemplifies the structure of two inflatable air bags, and in other embodiments, the number of the inflatable air bags may be three, four or more. In addition, the upper and lower sub-airbags in the embodiment are divided by one complete airbag, and in other embodiments, the upper and lower sub-airbags may be two separate complete airbags as long as the connection sealing performance of the two separate complete airbags is ensured.

In one example, the mask body 1 is made of a hard high polymer transparent plastic material; two sides of the mask body 1 are respectively provided with a circular avoiding hole with the diameter of 1cm, and a rubber film with a cross-shaped opening is arranged in the avoiding hole, so that a patient carrying the gastric tube can pass the gastric tube out of the avoiding hole; the film can firmly fix the gastric tube, so that the risk of tube detachment can be reduced, and meanwhile, air leakage can not happen to a patient without the gastric tube, and related work of sealing operation is reduced.

In one example, a window of 6cm x 8cm is further formed in the mask body 1, a window door 14 is arranged in the window, the window door 14 is hinged to the mask body 1, and the opening and closing range of the window door 14 can reach 180 degrees, so that when a patient needs to drink water or suck phlegm, the patient can conveniently operate by directly opening the window door 14 without taking down the mask. A ring of rubber gasket is arranged at the edge of the window 14 and/or the window, so that the air tightness of the mask can be improved, and air leakage can not occur in the using process.

It will be appreciated that a window lock may be provided between the window 14 and the mask body 1 to prevent the window 14 from opening automatically, and the window lock may refer to a window lock structure commonly used in the art.

In one example, the headband 3 includes a child headband and a parent headband; one end of the sub-head belt is connected with the mask body 1 or the forehead part 2, and the other end of the sub-head belt is configured as a sub-buckle; one end of the female head band is connected with the mask body 1 or the forehead part 2, and the other end of the female head band is configured as a female buckle; the male button and the female button can form buckling connection.

Specifically, the headband 3 is made of soft cotton material, taking the headband 3 on the forehead component 2 as an example, the headband 3 is provided with two parts, namely a sub-headband and a mother-headband, and one ends of the sub-headband and the mother-headband are respectively connected with two ends of the forehead component 2; the other end of the sub-head belt is constructed into a rack structure, the rack structure is configured into a rigid high polymer plastic material, a plurality of isosceles right triangle-shaped teeth 31 with right-angle sides of 5mm are arranged on the rack structure, and the distance between every two teeth 31 is 1 mm; the other end of the headband is configured to include a limiting shell 32 and a clamping pin 33, the limiting shell 32 is provided with a through channel 35 for the rack structure to pass through, the clamping pin 33 movably penetrates through the shell, one end of the clamping pin 33 is located in the through channel 35, and a compression spring 34 is connected between the end and the limiting shell 32.

When the headband 3 needs to be tightened during adjustment, the clamping needle 33 slides along the inclined plane of the teeth 31 to compress the spring 34 only by pulling the sub headband, and after reaching the peak of the teeth 31, the clamping needle is clamped between the next teeth 31 under the elastic force of the compression spring 34. When the headband 3 needs to be loosened, the clamping pins 33 only need to be pulled outwards, and the lower ends of the clamping pins 33 can be loosened freely as long as the lower ends of the clamping pins 33 are higher than the vertexes of the teeth 31. Therefore, the tightness can be accurately adjusted, and the phenomenon of firmness reduction caused by overlong use time can be avoided.

In one example, the female buckle on the forehead part 2 is connected with the female buckle on the mask body 1, so that after the mask is worn, all the head bands 3 form an I shape, and the stability of the mask when the mask is worn is guaranteed.

In one example, the forehead member 2 includes a forehead airbag and a housing; the casing is connected with bandeau 3, is provided with the holding tank that is used for holding the forehead gasbag on the casing, and the forehead gasbag is located the holding tank.

Specifically, the casing is a rectangle of transparent plastics material of rigid polymer, and its length is: 7cm, width: 3 cm. The casing is used for offering an holding tank towards facial one side, is equipped with the gasbag of a soft silica gel material in the holding tank, and the gasbag upper end still is equipped with one and aerifys the hole, and aerifys downthehole design and have a check valve. Thus, the squeezing condition of the forehead skin can be changed by adjusting the filling degree of the air bag.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
