Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a non-invasive ventilator mask. Background Art

[0002] In order to prevent the edge of the ventilator mask from causing redness, indentation, or even pressure sores on the patient's mouth, nose, and face, an improvement method of setting an airbag on the edge of the ventilator mask has emerged in the prior art. Among them, two airbags are set side by side on the edge of the ventilator mask, and the two airbags are alternately filled and act on different positions of the mouth, nose, and face, which has a significant effect on improving pressure injuries. For the shape of each airbag, in order to ensure the sealing of the ventilator mask, it is generally set to a ring-shaped airbag with the same contour as the edge of the ventilator mask.

[0003] However, the width of this shape of airbag is only half of the edge of the ventilator mask, so the contact area with the local skin is reduced by half each time it is used compared to the direct contact between the edge of the ventilator mask and the skin. When this airbag covers bony protrusions such as the bridge of the nose and mandible, redness and indentation will be more obvious, and pressure injuries will be more likely to occur. Utility Model Content

[0004] The utility model aims to provide a non-invasive ventilator mask to solve the technical problem in the prior art that an air bag having the same edge contour as the mask is more likely to cause pressure sores when in contact with bone protrusions due to a reduced local contact area.

[0005] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0012] As a preferred solution of the utility model, the mask is provided with a sputum suction port, and a buckle cover is movably provided on the sputum suction port.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 to Figure 2 As shown, the utility model provides a non-invasive ventilator mask, comprising a mask 1 and a surrounding airbag assembly 2 arranged on the edge of the mask 1, and the surrounding airbag assembly 2 is connected to an inflation and deflation assembly. In the device, the surrounding airbag assembly 2 is arranged as a whole on the opening edge of the mask 1, acting as a medium in contact with the skin surface.

[0023] During the oxygen inhalation process, the cool oxygen passing through the respiratory tract is prone to produce mucus and sputum, so the device is also provided with a sputum suction port on the mask 1, which can facilitate sputum suction for the patient during the oxygen supply period. A buckle cover 8 is movably provided on the sputum suction port to ensure that the internal oxygen will not flow out when the mask 1 is used normally.

[0024] In addition, the surrounding airbag assembly 2 is movably connected to the edge of the mask 1 through a connector. The connector can be a connector such as a buckle or adhesive, so as to facilitate the disassembly of the entire annular airbag assembly, and facilitate the secondary use of the surrounding airbag assembly 2 if necessary, and facilitate the classification and recycling of various components of the medical device if there is no need.

[0025] Furthermore, at least two expansion elastic bands 6 are provided on the mask 1, and the expansion elastic bands 6 can be made of elastic material to adapt to patients of different body shapes. The ends of the two expansion elastic bands 6 can be provided with connecting buckles, one end of the two expansion elastic bands 6 is connected to the side of the mask 1, and the other end is connected to each other behind the head, so that the whole device is fixed on the patient's face.

[0026] Among them, since the breathing machine mask 1 has certain requirements for the overall airtight performance, the elastic band is required to be tied tightly to prevent oxygen from escaping from the edge of the breathing machine mask 1. The elastic band that fits the face tightly will cause certain pressure on the facial skin.

[0027] Therefore, in the present device, the expansion elastic band 6 gradually expands from the position where it is connected to the mask 1 to the other side to form an outward expansion shape, a flexible breathable dressing is provided on the inner wall of the expansion elastic band 6, and the expansion elastic band 6 is fitted to the cheek position through the flexible breathable dressing.

[0028] Among them, the gradually expanding outward shape can enlarge the contact area between the elastic band and the face, thereby reducing the pressure on the local skin of the face. The provision of a flexible breathable dressing can, on the one hand, slow down the temperature rise efficiency of the fitting part, so that the fitting part maintains a low temperature, breathable and dry environment. On the other hand, it can provide a flexible fitting surface, which reduces the pressure while making it more comfortable to use.

[0029] Furthermore, the expansion elastic band 6 is provided with a plurality of ventilation holes 7, which can keep the face ventilated and dry, forming a good biological environment.

[0030] like Figure 1 As shown, the surround airbag assembly 2 includes an inner ring airbag 21 and an outer ring airbag 22, and the inner ring airbag 21 and the outer ring airbag 22 are respectively arranged around the inner edge and the outer edge of the mask 1, and a first pressure-relief airbag 3 and a second pressure-relief airbag 4 are arranged between the inner ring airbag 21 and the outer ring airbag 22, and the first pressure-relief airbag 3 is connected to the inner ring airbag 21, and the second pressure-relief airbag 4 is connected to the outer ring airbag 22.

[0031] The first pressure-relief airbag 3 and the second pressure-relief airbag 4 are both composed of a plurality of main airbags 5 , wherein the main airbags 5 in the first pressure-relief airbag 3 and the main airbags 5 in the second pressure-relief airbag 4 are arranged crosswise with each other.

[0032] The current alternating airbags usually use the principle of acting on different skin positions to prevent long-term compression of the same position from causing local skin pressure sores. However, the shapes of the two sets of airbags are set to be the same as the opening contour of the mask 1, and are arranged side by side on the edge of the mask 1 opening, which makes the width of a single airbag only half of the edge of the mask 1 opening. Therefore, when used alone, it acts on the facial bony protrusions (nose bridge, mandible), and under the dual effects of halving the contact area and greater pressure on the bony protrusions, it is more likely to cause pressure sores.

[0033] Therefore, the present device arranges the two sets of alternating first pressure-relief airbags 3 and second pressure-relief airbags 4 to contain a plurality of main airbags 5, and each main airbag 5 is extremely close to the width of the opening edge of the mask 1 (the true width of the main airbag 5 is the width of the opening edge of the mask 1 minus the width of the inner ring airbag 21 or the outer ring airbag 22, but because the inner ring airbag 21 or the outer ring airbag 22 only plays a sealing role, its width can be very narrow, so the width of the main airbag 5 can be extremely close to the width of the opening edge of the mask 1), thereby increasing the width of the airbag (the airbag in contact with the bony protrusion) and increasing the contact area, thereby reducing the pressure at the local position (the bony protrusion).

[0034] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
