Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a detachable breathing mask pressure ulcer prevention pad. Background Technology

[0002] A breathing mask is a medical device, usually made of soft material, that covers a patient's mouth and nose to provide oxygen or other respiratory support. It is widely used in emergency rooms, operating rooms, ICUs (Intensive Care Units), and other medical settings to help patients breathe or maintain respiratory function. Medical breathing masks come in various types and sizes, allowing for selection based on the patient's specific needs. However, common breathing masks often lack proper cushioning and sealing mechanisms at the point of contact with the patient's face, requiring external force to achieve a tight seal. This can easily lead to pressure sores on the facial skin during non-invasive mechanical ventilation, and the mask's poor fit can cause air leakage, increasing the risk of skin damage and infection at the mouth and nose. Consequently, patients may be unable to continue high-quality non-invasive ventilation and require invasive ventilation, increasing patient suffering, complications, and medical costs.

[0018] Reference Figures 1 to 5 As shown, this utility model provides a detachable breathing mask pressure ulcer prevention pad, including: a buffer layer 2, a base groove is formed on the upper surface of the buffer layer 2, a base plate 1 is fixedly connected in the base groove, and a fitting column 4 is symmetrically connected on the upper surface of the base plate 1. A fastening groove 10 is formed on the arc surface of the fitting column 4, and a fitting groove 9 is formed on the lower surface of the breathing mask body 6 relative to the position of the fitting column 4. An installation groove is formed on the inner side of the fitting groove 9 relative to the position of the fastening groove 10, and a fastening strip 8 is fixedly connected in the installation groove. The fitting column 4 is fixedly connected in the fitting groove 9 by the fastening strip 8. At the same time, an abutment layer 5 is fixedly connected to the lower surface of the buffer layer 2, and an antibacterial layer 7 is fixedly connected to the lower surface of the abutment layer 5.

[0019] In this embodiment, the pad body, through the cooperation of the interlocking post 4 and the fastening strip 8, can be easily attached and detached at the edge of the lower surface of the breathing mask body 6. When the patient uses the breathing mask body 6 for non-invasive ventilation, the pad body can act as a buffer sealing mechanism between the breathing mask body 6 and the patient's facial skin. This not only enhances the sealing performance of the breathing mask body 6 and the patient's face, but also reduces the pressure on the patient's face, thereby effectively enhancing the anti-pressure ulcer effect of the pad body. The antibacterial layer 7 is made of antibacterial treated pure cotton fabric, which can provide auxiliary antibacterial treatment for the skin at the patient's face. The abutment layer 5 and the buffer layer 2 are both made of medical silicone. The liquid filled in the cavity of the abutment layer 5 can not only help enhance the fit between the abutment layer 5 and the patient's face, but also help dissipate heat, reducing the chance of sweating due to heat at the patient's face. In addition, it can work with the buffer layer 2 to reduce the pressure on the patient's face, enhancing the anti-pressure ulcer effect of the pad body and ensuring that the patient can undergo non-invasive ventilation smoothly.

[0020] In a preferred embodiment, the buffer layer 2, the substrate 1, and the abutment layer 5 are combined together to form the main body of the pad, and the buffer layer 2 has an overall isosceles triangular structure, while the sharp corners of the buffer layer 2 are all arc-shaped.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 5The structural dimensions of the main body of the liner are adapted to the structural dimensions of the lower surface edge of the main body of the breathing mask 6, and the arc-shaped structure at the sharp corner of the buffer layer 2 can help enhance the safety of the main body of the liner during actual use.

[0022] As a preferred embodiment, the base groove opened on the upper surface of the buffer layer 2 is an isosceles triangle structure, and two sets of positioning grooves are symmetrically opened on both sides of the three sides of the base groove. All six sets of positioning grooves are elongated structures, and the cross-section of the positioning grooves is semi-circular.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The positioning grooves on both sides of the base groove can help enhance the stability of the substrate 1 in the base groove, and the substrate 1 can also help enhance the shaping effect of the buffer layer 2.

[0024] In a preferred embodiment, the substrate 1 has an isosceles triangular structure. The lower surface of the substrate 1 is fixedly connected to the bottom of the base groove cavity by adhesive, and the dimensions of the substrate 1 and the base groove are compatible. The positions of the two sides of the substrate 1 relative to the positioning groove are connected to the positioning strips 3, and the dimensions of the positioning strips 3 and the positioning groove are compatible.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 Both the substrate 1 and the positioning strip 3 are made of medical-grade plastic, and the adhesive is made of medical-grade adhesive, which can help enhance the stability of the fixed connection between the substrate 1 and the buffer layer 2, thereby ensuring that the pad body can be easily attached to and detached from the breathing mask body 6.

[0026] In a preferred embodiment, multiple sets of interlocking pillars 4 are fixedly connected at equal intervals on three sides of the upper surface of the substrate 1, and the multiple sets of interlocking pillars 4 are all cylindrical in shape, with the upper end of the interlocking pillar 4 having a frustum-shaped structure. At the same time, the fastening groove 10 opened on the arc surface of the interlocking pillar 4 has an annular structure, and the cross-section of the fastening groove 10 has a semi-circular structure, with the edge at the opening of the fastening groove 10 having an arc-shaped structure.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 5 The fitting post 4 is made of medical plastic. The frustum-shaped structure at the top of the fitting post 4 reduces the difficulty of fitting the post 4 into the fitting groove 9, thereby helping to improve the ease of installation between the pad body and the breathing mask body 6. At the same time, the edge structure at the opening of the fastening groove 10 reduces the chance of accidentally damaging the fastening strip 8 when the pad body is disassembled.

[0028] In a preferred embodiment, the fitting groove 9 on the lower surface of the breathing mask body 6 has a cylindrical structure, the size of the fitting groove 9 and the fitting column 4 are adapted to each other, and the fastening strip 8 fixedly connected in the fitting groove 9 has a circular structure, the size of the fastening strip 8 and the fastening groove 10 are adapted to each other, and the axial section of the fastening strip 8 has a circular structure.

[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 5 The sizes of the fitting groove 9 and the fitting post 4 are matched, which can help enhance the stability of the fixed connection between the pad body and the breathing mask body 6. The fastening strip 8 is made of medical silicone material. The structure of the fastening strip 8 can effectively enhance its elasticity, thereby enhancing the abutment and limiting effect of the fastening strip 8 in the fastening groove 10 and reducing the probability of the pad body accidentally detaching.

[0030] In a preferred embodiment, the dimensions of the lower surfaces of the abutment layer 5 and the buffer layer 2 are matched, the cross-section of the abutment layer 5 is a U-shaped structure, and the cavity inside the abutment layer 5 is filled with liquid. At the same time, the lower surface of the abutment layer 5 is fixedly connected to the antibacterial layer 7, and the dimensions of the antibacterial layer 7 and the lower surface of the abutment layer 5 are matched.

[0031] In this embodiment, as Figure 2 , Figure 3 and Figure 5 The liquid filling the abutment layer 5 can not only help enhance the overall deformability of the abutment layer 5, but also help improve the heat dissipation effect at the point where the patient's facial skin is adhered. At the same time, the antibacterial layer 7 can provide corresponding antibacterial protection at the point where the patient's panel is adhered, enhancing the safety of the patient when using the main body of the breathing mask 6.
