Description

Wearing a pressure relief device for respirators

The invention relates to an accessory for wearing a respirator, in particular to a decompression device for wearing a respirator.

Referring to FIG. 1 , a conventional respirator 1 includes a cover body 11 suitable for communicating with an air intake source (not shown in the figure), and a wearing part 12 connected to the cover body 11 and suitable for wearing. Wherein, the wearing part 12 usually uses an elastic elastic band, or a belt body configured with an adjustment mechanism such as Velcro, so that the cover body 11 can be stably attached to the wearer's face to ensure the effect of assisting breathing.

Yet, because the wearer of this existing respirator 1, usually all is bedridden and can't take care of oneself, even unconscious patient. In the case of needing to rely on the existing respirator 1 to breathe, the wearing part 12 will inevitably continue to cause pressure on the wearer due to long-term wearing, and the wearer cannot adjust it voluntarily. If the caregiver is negligent and does not adjust at a fixed time, although the wearer may not be able to express the discomfort of wearing it independently, the pressure caused by the wearing part 12 for a long time will still inevitably cause crushing. If you think from the perspective of the wearer, the wearing method of the existing respirator 1 is obviously not ideal and needs to be improved. technical solutions.

Therefore, the object of the present invention is to provide a wearable decompression device for a respirator that can improve comfort and reduce the probability of pressure injury.

Therefore, the wearing decompression device of the respirator of the present invention comprises a wearing strip adapted to be fixed at both ends of the respirator, and at least two decompression pads made of low-resilience foam and spaced apart from each other on the wearing strip.

Each of the decompression pads includes a pad body formed with a plurality of perforations for the wearing strip to pass through, and an inner skin-friendly layer arranged on the inner side of the pad body.

The effect of the present invention is that when the wearer wears the respirator through the wearing strip, the material of the at least two pressure-relief pads can reduce the pressure of the wearing strip toward the wearer by the low-resilience foam material of the at least two pressure-relief pads, and when the at least two pressure-relief pads contact the wearer with the inner skin-friendly layer, the comfort can be further optimized. Under the synergistic effect of reducing pressure and optimizing contact comfort, the probability of crush injury of the wearer can indeed be effectively reduced.

Other features and effects of the present invention will be clearly presented in the implementation manner with reference to the drawings, wherein: 1 is a side view illustrating an existing respirator; FIG. 2 is a perspective view illustrating a first embodiment of a decompression device for wearing a respirator of the present invention; FIG. Example; Fig. 7 is a partially enlarged side view illustrating one of the third embodiment of the decompression device worn by the respirator of the present invention; Fig. 8 is a side view illustrating one of the fourth embodiment of the decompression device worn by the respirator of the present invention; and Fig. 9 is a schematic diagram illustrating the use of the fourth embodiment.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

Referring to Fig. 2, it is one of the first implementation of the wearing decompression device of the respirator of the present invention For example, it is suitable for cooperating with a respirator mask 9. The first embodiment includes a wearing strip 2 suitable for fixing both ends of the respirator mask 9, and two pressure relief pads 3 which are made of low resilience foam and are spaced apart from each other on the wearing strip 2. Wherein, the wearing strip 2 is selected from an elastic elastic band or a round tube. The respirator mask 9 will be additionally connected to an air intake source (not shown in the figure) during practical application, thereby introducing gas for the user to breathe to the respirator mask 9, and subsequent technical details of this part are not the technical focus of the present invention, and will not be repeated.

Referring to FIG. 2 and FIG. 3 at the same time, each of the pressure relief pads 3 includes a pad body 31 formed with a plurality of perforations 310 for the wearing strip 2 to pass through, and an inner skin-friendly layer 32 disposed inside the pad body 31 . In terms of material, the material of the cushion body 31 is polyurethane, and the density of the cushion body 31 is 20~50kg/m ³ , the washback coefficient is less than 10%, and the hardness measured by ASKER rubber hardness meter F is 10~50. Through the aforementioned material properties of the pad body 31 , the requirements for positioning the wearing strip 2 and the material properties of the wearing strip 2 can be met, thereby achieving the purpose of cushioning and decompression. The inner skin-friendly layer 32 is a polyurethane waterproof film, thereby providing a skin-friendly effect for optimizing comfort on the side that contacts the wearer.

The pad body 31 of each decompression pad 3 is a rectangle whose long side is approximately parallel to the wearing strip 2. Specifically, the extension length of the individual pad body 31 is based on the principle that it can be attached to one side of the wearer's cheek and then extend to the ear of the same side. The perforations 310 of each pad 31 are formed by a plurality of hole pairs H spaced apart from each other by a first distance D1. Each of the hole pairs H has two The through holes 310 are spaced apart by a second distance D2 smaller than the first distance D1. The wearing strip 2 is set through one of the perforation 310 of any one of the hole pair groups H from outside to inside, and then passed through the other through hole 310 of the same hole pair group H from inside to outside, thereby forming a plurality of outer sections 21 attached to the wearing strip 2 at intervals and having a length equal to the first distance D1, and a plurality of inner sections 22 attached to the inside of the wearing strip 2 at intervals and having a length equal to the second interval distance D2.

It should be noted that since the decompression pads 3 are made of elastic and twistable materials, when the wearing strip 2 is inserted through the perforations 310, the decompression pads 3 will inevitably be twisted as shown in FIG. Accordingly, the first spacing distance D1, the second spacing distance D2, and the lengths of the outer section 21 and the inner section 22 shown in FIG. 3 are related to the description that the perforations 310 are in their original positions when the decompression pad 3 has not yet undergone distortion.

Referring to Fig. 3 and Fig. 4 at the same time, the first spacing distance D1 is 2 to 10 times of the second spacing distance D2, if the first spacing distance D1 as shown in Fig. 3 is 3 times of the second spacing distance D2, the length of each outer section 21 of the wearing strip 2 is also 3 times of the length of the inner section 22. When wearing the first embodiment, although the wearing strip 2 has a slightly poorer skin-friendly effect than the inner skin-friendly layer 32, the length of the inner sections 22 is relatively short, which can moderately reduce the area contacting the wearer to optimize the skin-friendly effect, and at the same time generate a certain amount of friction through the material of the wearing strip 2. In addition, in addition to simply using the material of the decompression pads 3 to exert the effect of dispersing the pressure, the wearing strip 2 is repeatedly bent inside and outside to pass through the decompression pads 3, which can not only produce a supporting effect on the decompression pads 3 and optimize the overall structure, thereby avoiding the twisting and turning of the decompression pads 3 to optimize the user's operability, but also further improve the effect of pressure distribution. In response to the main appeal of the decompression purpose, the multiplier benefits are produced, and the probability of pressure injuries for the wearer after wearing for a long time is indeed reduced.

Referring to FIG. 5 together with FIG. 4, FIG. 5 shows another implementation of the first embodiment, the inner skin-friendly layer 32 of each decompression pad 3 is adhesive. Accordingly, in the case where the adhesive has a certain viscosity, this embodiment can optimize the fit of the decompression pads 3 attached to the wearer, and ensure that the decompression pads 3 can produce the expected decompression and pressure division effects on the position where the pressure is most likely to be concentrated when the decompression pads 3 are positioned at specific positions.

Referring to Fig. 6, it is a second embodiment of a wearing decompression device for a respirator of the present invention. The difference between this second embodiment and the first embodiment is that each of the decompression pads 3 also includes an outer skin-friendly layer 33 formed on the opposite side of the inner skin-friendly layer 32, and the material of the outer skin-friendly layer 33 is also a polyurethane waterproof film. Specifically, in the second embodiment, skin-friendly materials are formed on both the inner and outer sides of the decompression pad 3 , so that in addition to having a fool-proof effect due to the non-directionality of the inner and outer sides when wearing it, the overall structural strength of the decompression pads 3 is further optimized, so that the operability of the operator in putting on or assisting the wearer in wearing is more excellent.

Referring to Fig. 7, it is a third embodiment of the wearing decompression device of the respirator of the present invention. The difference between this third embodiment and the first embodiment is: the pad body 31 of each of the decompression pads 3 has an extension 311 extending in a direction parallel to the wearing strip 2, and two respectively connected to the opposite ends of the extension 311 and the width along the direction perpendicular to the wearing strip 2 is larger than the wide end 312 of the extension 311. In the third embodiment, through the equal-width end portion 312 , the operator can have a larger solid structure to hold when wearing or assisting in wearing, so that the convenience of various operations can be further optimized.

Referring to Fig. 8 , it is a fourth embodiment of the wearing decompression device of the respirator of the present invention. The difference between this fourth embodiment and the first embodiment is that the pad body 31 of each decompression pad 3 is formed with three perforations 310, and has an extension 311 extending along a laterally extending auxiliary line L, a front end 313 connected to the front end of the extension 311 and having two expansion sides 318 bent in opposite directions away from the auxiliary line L, and a front end 313 connected to the extension 31 1 at the rear end, and has a rear end portion 314 extending downwards along a direction perpendicular to the auxiliary line L with an abutting area 319 . Wherein, the three perforations 310 are respectively located at the extension portion 311 , the front end 313 , and the rear end 314 , and the two perforations 310 at the extension 311 and the front end 313 are located on the auxiliary line L, and the perforation 310 at the rear end 314 is located relatively below the auxiliary line L. That is, only one of the through holes 310 is not on the same straight line (the auxiliary line L) as the other two of the through holes 310 .

Referring to Fig. 8 and Fig. 9 at the same time, the decompression pad 3 on one side is relatively worn As far as the position of the wearer is concerned, the design of the through-holes 310 is not on the same straight line, so that after the wearing strip 2 is passed through the through-holes 310, the wearing strip 2 can extend relatively downward when one of the expanded sides 318 of the front end 313 is abutted against the upper part of the wearer's ear, thereby avoiding the bending of the pressure relief cushion 3 due to the extending direction of the wearing strip 2, and ensuring that the expanded side 318 can stably abut against the upper part of the wearer's ear. , and make the abutment area 319 of the rear end portion 314 conform to the wearer, and optimize the effects of decompression and pressure division by virtue of its relatively large area.

To sum up, when wearing the decompression device of the respirator of the present invention, when the wearer wears the respirator mask 9 through the wearing strip 2, in addition to optimizing the comfort through the inner skin-friendly layer 32, the material of the decompression pads 3 and the pressure dividing effect produced by the wearing and fixing method of the wearing strip 2 can reduce the pressure of the wearing strip 2 towards the wearer. Under the synergistic effect of reducing pressure and optimizing contact comfort, it can indeed effectively reduce the probability of the wearer's crush injury. Therefore, can really reach the purpose of the present invention.

But what is described above is only an embodiment of the present invention, and should not limit the implementation scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope covered by the patent of the present invention.
