Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary medical equipment technology, and in particular to a non-invasive ventilator facial pressure ulcer prevention pad. Background Technology
[0002] In the neonatal ward, some newborns have underdeveloped lungs and experience respiratory distress, especially premature infants who lack pulmonary surfactant, leading to difficulty breathing or respiratory distress. Therefore, they require oxygen therapy, and in some cases, mechanical ventilation is necessary to help them breathe and improve their survival rate. Clinically, a non-invasive ventilator is typically connected to the newborn via a breathing mask.
[0003] When an infant wears a breathing mask, the mask is placed over the infant's nose. The left and right sides of the mask are secured to the cap via straps. On one hand, the mask needs to fit snugly against the face of the premature infant; otherwise, oxygen delivery may be ineffective, leading to respiratory distress. On the other hand, prolonged pressure from the mask can easily cause pressure sores on the face of premature infants. Currently, clinically, the entire cap structure is used to address pressure sores on the head and neck of newborns, with gauze pads placed under the two straps to relieve pressure. However, the gauze is prone to shifting during use and offers poor protection, affecting comfort. Therefore, breathing masks do not provide a good solution for pressure sores on the face.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0027] Example 1:
[0028] This embodiment provides a non-invasive ventilator facial pressure ulcer prevention pad, such as... Figures 1-6 As shown, the device includes an anti-pressure pad, comprising a first pad 1 that adheres to the bridge of the nose and two second pads 2 that adhere to the left and right sides of the face. The first pad 1 is bent upwards towards the second pads 2, and the two second pads 2 are respectively connected to the left and right sides of the first pad 1, and are symmetrically arranged about the center line of the first pad 1. The first pad 1 connects the two second pads and provides protection for the bridge of the nose.
[0029] Specifically, the pressure-absorbing pad has a certain thickness to increase the contact area and buffer pressure. Preferably, the thickness of the pressure-absorbing pad is 2mm-10mm. If the pressure-absorbing pad is too thin, it will not have a pressure-absorbing effect, while if it is too thick, it will affect its breathability. Therefore, the thickness of the pressure-absorbing pad in this embodiment is set within a certain range to ensure good pressure-absorbing effect while maintaining good breathability.
[0030] In this embodiment, when the pressure ulcer prevention pad is in use, the first pad 1 is attached to the baby's nose bridge, and the two second pads 2 are attached to the left and right cheeks respectively. When the breathing mask is worn on the baby's face, the lower side of the breathing mask is attached to the first pad 1, and the fixing straps on the left and right sides of the breathing mask are attached to the two second pads respectively to extend to the sides and connect to the two sides of the cap, thereby fixing the breathing mask.
[0031] In this embodiment, the first pad 1 is pressed under the breathing mask, and the two side straps are pressed under the two fixing straps. The design of the anti-pressure pad structure in this embodiment provides pressure relief at the center of gravity of the breathing mask through the first pad 1, and the two side straps 2 alleviate the pressure of the two fixing straps on the face, increasing the pressure-bearing area and dispersing the pressure force, thereby alleviating facial pressure sores and improving the newborn's skin comfort. It is specifically designed for actual clinical pressure sore sites, improving the infant's skin feel and comfort, and is lightweight with better pressure sore prevention. Furthermore, the first pad 1 and the two second pads 2 are connected to form a whole, which can simultaneously protect the bridge of the nose and cheeks. The integrated structure reduces relative displacement and provides good positioning.
[0032] As a preferred embodiment, such as Figure 3 As shown, the width a of the second pad 2 is greater than the width b of the first pad 1. The anti-pressure sore pad of this embodiment is designed according to the proportion of the infant's facial features, so that the area of the second pad 2 on the face is greater than the area of the first pad 1 on the bridge of the nose, thereby improving comfort and maximizing the pressure area without affecting the use of the breathing mask, thus reducing the feeling of pressure.
[0033] Specifically, the widths of the first pad 1 and the second pad 2 are set according to the usage, so that they can be placed under the bottom of the breathing mask and the fixing strap without affecting the use of the breathing mask. Preferably, the width 'a' of the first pad 1 is 5mm-20mm; the maximum width 'b' of the second pad 2 is 10mm-30mm. Preferably, the width of the first pad is equal along its length. Alternatively, the width of the first pad 1 can be unequal, and when the widths of the first pads are unequal, the width of the middle section of the first pad 1 is the largest.
[0034] As a preferred embodiment, such as Figure 6 As shown, the pressure-relieving pad includes a fixing layer 3, a buffer layer 4, and a skin contact layer 5, which are connected sequentially from top to bottom. The fixing layer 3, buffer layer 4, and skin contact layer 5 can be connected by adhesive or heat pressing. When the pressure-relieving pad is applied to the face, the skin contact layer 5 is positioned close to the skin. The fixing layer 3 can have a fixing structure for securing the cord, which can be adhesive tape. The buffer layer 4 can be a sponge layer or an inflatable layer, possessing a certain degree of elasticity and providing good cushioning.
[0035] Preferably, such as Figure 6 As shown, the skin contact layer 5 is a silicone layer, which has good skin affinity and flexibility, and can protect the baby's delicate skin. An adhesive layer 6 is provided below the silicone layer, and a protective film 7 is provided below the adhesive layer 6.
[0036] In this embodiment, the pressure-relief pad is attached to the underside of the adhesive layer 6 via a protective film 7 when not in use, thus protecting the adhesive layer 6. When in use, the protective film 7 is peeled off from the adhesive layer 6, and the pressure-relief pad is then attached to the infant's face via the adhesive layer 6. The adhesive layer 6 is a medical-grade adhesive layer to prevent skin damage.
[0037] As a preferred embodiment, the first pad 1 and the two second pads 2 are an integral structure, which is simple in structure, low in manufacturing cost, and has good integrity.
[0038] As a preferred embodiment, such as Figures 1-3 As shown, the first pad 1 is curved in an arc shape. The arc-shaped first pad 1 can fit snugly on the bridge of the nose and provides good comfort.
[0039] In addition, such as Figure 4 As shown, the first pad 1 can also be bent into a triangular shape. The triangular first pad 1 has a larger width in the middle, which increases the contact area with the bridge of the nose and provides better protection.
[0040] In a preferred embodiment, the second pad 2 is rounded and smooth to avoid rubbing against the skin and affecting comfort. Preferably, as shown below... Figure 3and Figure 5 As shown, the second pad 2 is circular or elliptical. Alternatively, the second pad 2 can also be other shapes with smooth edges.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
