Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a non-invasive ventilator mask for preventing pressure sores. Background Technology

[0002] Non-invasive ventilators are a common clinical treatment for patients with severe pneumonia, COPD, and other diseases. They have been widely promoted due to their simple operation and non-invasiveness. During the application of non-invasive ventilators, the ventilator mask needs to be tightly fitted to the patient's face to avoid gaps that could lead to air leakage. However, this process can easily lead to complications such as facial pressure sores, which can affect the effectiveness of the treatment and the patient's recovery.

[0003] Currently, to prevent facial pressure ulcers, protective dressings are often used to isolate the mask from contact with the face. However, because patients may move their heads involuntarily or push the ventilator mask involuntarily after falling asleep, the mask may shift. Since the protective dressing is fixed to the patient's face, the ventilator mask and the protective dressing may become misaligned, causing the mask to come into contact with the face again. This fails to prevent the formation of pressure ulcers. Therefore, this application provides a non-invasive ventilator mask to prevent pressure ulcers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a non-invasive ventilator mask to prevent pressure sores, thereby solving the problem that the existing ventilator mask and protective dressing are misaligned, resulting in the inability to prevent the formation of pressure sores.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A pressure ulcer prevention non-invasive ventilator mask includes a mask body, with symmetrical fixing straps fitted on the outer side of the mask body, and an oxygen delivery tube connected to one side of the mask body; and an adapter assembly for installing foam dressing at the edge of the mask, the adapter assembly being connected to the mask body.

[0007] Optionally, the adapter assembly includes a fixing kit that fits onto one side of the mask body, and a shaping band is fixedly connected to one side of the fixing kit.

[0008] Optionally, an elastic sleeve is fixedly connected to one side of the shaping belt, and the elastic sleeve is arranged in a "C" shape.

[0009] Optionally, both ends of the elastic sleeve are fixedly connected to pressure strips, and one side of each of the two pressure strips is fixedly connected to multiple anti-slip rings.

[0010] Optionally, a foam dressing is fitted onto the inner side of the elastic sleeve, and the foam dressing is in contact with the edge-pressing tape.

[0011] Optionally, a thickened skirt is provided on the side where the elastic sleeve connects to the shaping belt.

[0012] Optionally, the elastic sleeve is internally fixedly connected with a plurality of elastic ribs, the overall outline of the plurality of elastic ribs being a “V” shape, and the plurality of elastic ribs being arranged end-to-end inside the elastic sleeve.

[0013] Optionally, both ends of the elastic sleeve transition into the two pressure strips in an arc shape.

[0014] Optionally, the inner contour of the fixing kit is a "U" shape and is adapted to the edge of the mask body.

[0015] Optionally, the adapter assembly is made of rubber.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, by setting up a fixing kit and an elastic clip, the fixing kit is fitted onto the edge of the mask body, and the elastic clip holds and fixes the foam dressing, thus fixing the protective dressing to the edge of the ventilator mask. At the same time, because part of the foam dressing is engaged inside the elastic clip, it will not come into contact with the patient's face after absorbing sweat or tissue fluid at this location. This reduces the contact area between the moist foam dressing and the patient's face, further preventing the formation of pressure ulcers. This achieves the purpose of the protective dressing moving with the ventilator mask, avoiding the phenomenon of misalignment between the ventilator mask and the dressing, improving the effect of preventing pressure ulcers, and making the dressing easy to install and remove, which is convenient for medical staff.

[0018] By setting the edge-pressing strip, the foam dressing can be positioned to ensure contact with the patient's face, preventing the edges from lifting. It also limits the area of ​​the foam dressing. After the foam dressing is secured inside the elastic clip and adhered to the edge-pressing strip, medical staff can remove any excess foam dressing along the edges of the upper and lower edge-pressing strips. This makes it easier for medical staff to cut the foam dressing to ensure that its overall shape meets the usage requirements. Attached Figure Description

[0029] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0030] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0031] like Figures 1 to 3 As shown, an embodiment of this utility model provides a pressure ulcer-preventive non-invasive ventilator mask, including a mask body 1, with fixing straps 2 symmetrically fitted on the outer side of the mask body 1, the fixing straps 2 can fix the mask body 1 to the patient's face, and an oxygen delivery tube 3 is connected to one side of the mask body 1, the oxygen delivery tube 3 can deliver oxygen into the inner side of the mask body 1; and an adapter assembly, which is used to install foam dressing at the edge of the mask, the adapter assembly is connected to the mask body 1, the adapter assembly includes a fixing kit 4 fitted on one side of the mask body 1, a shaping band 5 fixedly connected to one side of the fixing kit 4, the inner contour of the fixing kit 4 is a "U" shape and is adapted to the edge of the mask body 1, and the adapter assembly is made of rubber.

[0032] With the fixing kit 4 and shaping band 5, the inner contour of the fixing kit 4 matches the edge contour of the mask body 1. The adapter is made of rubber and molded in one piece, which facilitates production and subsequent maintenance. The connection between the mask body 1 and the fixing kit 4 is a sleeve connection, which improves the convenience of disassembly and assembly in actual use. The overlapping area between the fixing kit 4 and the mask body 1 is large, which increases the stability and airtightness of the fixing kit 4 after sleeve connection. When fixing the ventilator mask to the patient's face, the strap needs to be tightened to improve the fit between the mask and the patient's face and avoid air leakage. During this period, the shaping band 5 will deform accordingly. The shaping band 5 extends the distance between the fixing kit 4 and the elastic clip 6 to provide the elastic clip 6 with movable deformation space, so that the elastic clip 6 can deform according to the patient's face, so that the foam dressing 10 can fit perfectly with the patient's face.

[0033] like Figures 1 to 3 As shown, an elastic sleeve 6 is fixedly connected to one side of the shaping belt 5. The elastic sleeve 6 is arranged in a "C" shape. A thickened skirt is provided on the side of the elastic sleeve 6 connected to the shaping belt 5. Since the elastic sleeve 6 needs to be stretched when fixing the foam dressing 10 so that the foam dressing 10 can enter the inner side of the elastic sleeve 6, the interrupted position of the elastic sleeve 6 will be stretched multiple times during this period, which will increase the possibility of breakage at that position. The thickened skirt is used to reinforce this position to avoid breakage. The internal fixed connection of the elastic sleeve 6 is... Multiple elastic ribs 7 are attached, which can greatly improve the elasticity of the elastic sleeve 6. When the elastic sleeve 6 deforms, the multiple elastic ribs 7 inside will deform simultaneously, thereby improving the fixing effect of the foam dressing 10 when the elastic sleeve 6 resets and clamps and fixes the foam dressing 10. The overall outline of the multiple elastic ribs 7 is a "V" shape. The multiple elastic ribs 7 are arranged in a head-to-tail manner inside the elastic sleeve 6. Both ends of the elastic sleeve 6 are arc-shaped and transition to the two pressure strips 8. This arrangement can make the bending of the foam dressing 10 smoother.

[0034] By using the elastic clip 6, the foam dressing 10 is clamped and fixed by the fixing kit 4 sleeved on the edge of the mask body 1, allowing for convenient and quick assembly and disassembly of the foam dressing 10. This facilitates use by medical staff. Simultaneously, the foam dressing 10 adheres to the pressure strips 8 on both sides, ensuring contact between the foam dressing 10 and the patient's face. This increases the contact area, preventing pressure concentration and the formation of pressure ulcers due to insufficient contact area. Furthermore, the foam dressing 10 is limited by the anti-slip ring 9, preventing displacement of the foam dressing 10 caused by patient movement. Additionally, the foam dressing 10 maintains its position against the patient's face. The increased contact area, with a portion of the foam dressing 10 secured to the inside of the elastic clip 6, increases the absorbent capacity of the foam dressing 10 for sweat and tissue fluid. Because a portion of the foam dressing 10 is secured to the inside of the elastic clip 6, it will not come into contact with the patient's face after absorbing sweat or tissue fluid, thus reducing the contact area between the moist foam dressing 10 and the patient's face. This further prevents the formation of pressure ulcers, achieving the goal of the protective dressing moving with the ventilator mask, preventing misalignment between the ventilator mask and the dressing, improving the effectiveness of pressure ulcer prevention, and making dressing installation and removal more convenient for medical staff.

[0035] like Figures 1 to 3 As shown, both ends of the elastic sleeve 6 are fixedly connected with pressing strips 8, and one side of each pressing strip 8 is fixedly connected with multiple anti-slip rings 9. Foam dressing 10 is sleeved on the inner side of the elastic sleeve 6, and the foam dressing 10 is in contact with the pressing strips 8.

[0036] By setting the edge-pressing strip 8, the edge-pressing strip 8 can limit the foam dressing 10, allowing the foam dressing 10 to contact the patient's face, preventing the foam dressing 10 from curling up, and limiting the area of ​​the foam dressing 10. After the foam dressing 10 is snapped into the inner side of the elastic sleeve 6 and the foam dressing 10 is attached to the edge-pressing strip 8, the medical staff can remove the excess part of the foam dressing 10 along the edges of the upper and lower edge-pressing strips 8. This makes it easier for the medical staff to cut the foam dressing 10 to ensure that the overall shape of the foam dressing 10 meets the usage requirements. At the same time, removing the excess part of the foam dressing 10 can keep the volume of the foam dressing 10 within a relatively appropriate range, thereby avoiding the foam dressing 10 being too large and reducing the fixing effect of the elastic sleeve 6 on the foam dressing 10.

[0037] The working principle of the technical solution provided by this utility model is as follows:

[0038] When a patient uses a ventilator mask, first attach the fixation kit 4 to the edge of the mask body 1, ensuring a complete fit between the fixation kit 4 and the mask body 1 to improve stability and airtightness after installation. Then, insert the foam dressing 10 into the inner side of the elastic clip 6. By prying open the elastic clip 6, extend both ends outwards, allowing the foam dressing 10 to enter. Once the foam dressing 10 is in contact with the inner side of the elastic clip 6, release the elastic clip 6 at that position, allowing it to clamp and fix the foam dressing 10. Repeat this process until the foam dressing 10 is fully inserted. Insert the foam dressing 10 into the inner side of the elastic clip 6 and press it down so that the foam dressing 10 can fit with the upper and lower pressure strips 8. At this time, the excess foam dressing 10 can be trimmed along the edge of the upper and lower pressure strips 8 to ensure that the outline of the foam dressing 10 matches the upper and lower pressure strips 8. This completes the installation and fixation of the foam dressing 10. At this time, the mask body 1 can be fixed to the patient's face with the fixing strap 2. At this time, the foam dressing 10 is in contact with the patient's face to prevent the formation of pressure sores and can move with the ventilator mask, thereby avoiding the phenomenon of misalignment between the ventilator mask and the protective dressing.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
