Description

Technical Field

[0001] This utility model relates to the field of nursing technology, specifically to a protective device for preventing mechanical pressure injury to the nose caused by non-invasive ventilators. Background Technology

[0002] In the medical field, non-invasive ventilators are widely used for various patients requiring respiratory support, especially in the treatment of sleep apnea syndrome, chronic obstructive pulmonary disease, and acute respiratory failure, where they play a crucial role. However, despite providing essential respiratory support, prolonged use of a breathing mask can lead to mechanical pressure injuries to the nose, a problem that has long troubled both healthcare professionals and patients.

[0003] Traditionally, healthcare professionals have employed various measures to reduce the pressure of breathing masks on patients' noses, such as adjusting the mask's tightness and using soft padding. However, these methods often only alleviate the problem to a certain extent and cannot fundamentally prevent mechanical pressure injuries to the nose. Furthermore, due to individual differences, some patients have poor tolerance to breathing masks, and even with the aforementioned measures, nasal injuries are still difficult to avoid. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of the present invention is to provide a protective device for preventing mechanical pressure injury to the nose caused by non-invasive ventilators. This device has good fit, breathability and comfort, and can reduce the pressure of the breathing mask on the patient's nose, without affecting the normal use of the ventilator.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a protective device for preventing mechanical pressure injury to the nose caused by non-invasive ventilators, comprising:

[0006] A substrate having through holes that expose the patient's mouth and nose in the through holes;

[0007] An adhesive layer is disposed on the side of the substrate that is in contact with the patient's face;

[0008] A buffer layer is also provided on the side of the substrate that is in contact with the patient's face, and a ring is provided around the through hole;

[0009] A snap-fit ​​layer is provided on the side of the substrate away from the side that is in contact with the face, and the breathing mask is snapped onto the snap-fit ​​layer.

[0010] Preferably, the adhesive layer includes a first adhesive layer and a second adhesive layer, wherein the first adhesive layer is disposed around the edge of the through hole, and the second adhesive layer is disposed around the edge of the substrate.

[0011] Preferably, the adhesive layer has a release paper layer.

[0012] Preferably, the buffer layer is disposed between the first adhesive layer and the second adhesive layer, and the buffer layer has a plurality of vent holes.

[0013] Preferably, the snap-fit ​​layer is made of a flexible material and has an arc-shaped groove on the side that snaps into the breathing mask, and an absorbent layer is provided on the snap-fit ​​layer in the arc-shaped groove.

[0014] With the above structure, this utility model has the following advantages:

[0015] This application ensures that the patient can breathe freely through the mouth and nose by setting through holes in the substrate. The adhesive layer ensures that the protective device can fit tightly to the patient's face, increasing the stability of placement. The ventilation holes in the buffer layer help keep the skin dry and reduce skin discomfort caused by prolonged closure. The snap-fit ​​layer is made of flexible material, which increases the comfort of the device and makes the breathing mask more secure and less likely to slip off. The arc-shaped groove and water-absorbing layer design on the snap-fit ​​layer not only improves the stability of the breathing mask, but also absorbs the moisture generated by breathing, keeping the inside of the mask dry and comfortable. The release paper layer on the adhesive layer can be easily peeled off before use, ensuring that the adhesive layer can be cleanly and flatly attached to the patient's face.

[0016] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0023] Combined with appendix Figures 1-2 A protective device for preventing mechanical pressure injury to the nose caused by a non-invasive ventilator, comprising a base 1 and an adhesive layer, a buffer layer 7 and a snap-fit ​​layer 3 disposed on the base 1.

[0024] The substrate 1 has a through hole 2, which exposes the patient's mouth and nose. The substrate 1 can be made of soft, breathable silicone or pure cotton fabric. Different sizes of through holes 2 are designed according to patients of different ages to ensure that the mouth and nose are fully exposed.

[0025] The adhesive layer is set on the side of the substrate 1 that is in contact with the patient's face. The adhesive layer includes a first adhesive layer 5 and a second adhesive layer 6. The first adhesive layer 5 is set around the edge of the through hole 2, and the second adhesive layer 6 is set around the edge of the substrate 1. A release paper layer is provided on the adhesive layer. Both the first adhesive layer 5 and the second adhesive layer 6 are made of medical-grade silicone adhesive, which can perfectly fit the face.

[0026] The buffer layer 7 is also set on the side of the substrate 1 that is in contact with the patient's face, and is arranged in a circle around the through hole 2. The buffer layer 7 is set between the first adhesive layer 5 and the second adhesive layer 6, and several air vents are opened on the buffer layer 7. The buffer layer 7 can be made of memory foam or gel material, and the air vents are arranged in a honeycomb pattern to ensure good breathability.

[0027] The snap-fit ​​layer 3 is located on the side of the base 1 away from the face. The breathing mask is snapped onto the snap-fit ​​layer 3. The snap-fit ​​layer 3 is made of flexible material and has an arc-shaped groove on the side that snaps onto the breathing mask. An absorbent layer 4 is provided in the arc-shaped groove on the snap-fit ​​layer 3. The snap-fit ​​layer 3 can be made of medical-grade silicone or TPU, and the absorbent layer 4 is made of highly absorbent resin material.

[0028] When using the device of this application, first peel off the release paper, and use the first adhesive layer 5 and the second adhesive layer 6 to bond the base 1 to the patient's face, with the patient's mouth and nose located at the through hole 2 of the base 1. Then, wear the breathing mask of the non-invasive ventilator on the patient's face, so that the edge of the mask is locked in the groove of the locking layer 3. During breathing, the water droplets generated inside the mask flow along its inner wall to the groove and are absorbed by the absorbent layer 4. The locking layer 3 and the buffer layer 7 disperse the pressure of the breathing mask on the patient's face, preventing pressure trauma.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
