Description

Technical Field

[0001] This utility model relates to the technical field of non-invasive ventilators, and more precisely, to a facial pressure relief patch for non-invasive ventilators. Background Technology

[0002] Compared to traditional ventilators, non-invasive ventilators do not require endotracheal intubation; they only require a face mask for positive pressure ventilation. Using a non-invasive ventilator effectively avoids the pain and high cost of endotracheal intubation and can also prevent various complications such as pneumonia associated with traditional ventilators. Therefore, non-invasive ventilators are now widely used in clinical practice and have become an important device for the adjunctive treatment of respiratory failure, especially for patients with early acute respiratory failure and chronic respiratory failure.

[0003] When using a non-invasive ventilator, a mask is used to cover the patient's mouth and nose. Because prolonged mask use can damage facial skin, pressure-reducing patches are clinically necessary to reduce mask pressure. Existing pressure-reducing patches are usually cut on-site by healthcare professionals and placed directly on the patient's face, which does not provide a good fit to the facial structure or ensure a tight seal between the mask and facial skin. Furthermore, when the patient's face shakes, gaps can appear between the pressure-reducing patch and the face, causing it to detach and affecting its effectiveness.

[0004] In summary, there is a need in the field to improve existing facial pressure relief patches for non-invasive ventilators to enhance their stability after installation and their tightness in adhering to the face. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 and Figure 2 As shown, this application discloses a facial pressure-reducing patch for a non-invasive ventilator, comprising a pressure-reducing patch body 1, a protective cloth 2, an installation mechanism 3, and a protective mechanism 4. The pressure-reducing patch body 1 is a hollow triangle. The protective cloth 2 is wrapped around the side of the pressure-reducing patch body 1. The installation mechanism 3 is installed in conjunction with the protective cloth 2. The protective mechanism 4 is installed at the bottom of the pressure-reducing patch body 1. The pressure-reducing patch body 1 is fitted to the face through the protective mechanism 4. The installation mechanism 3 is fixedly installed around the head, and the pressure-reducing patch body 1 is driven to fit against the face by the protective cloth 2. With the installation mechanism 3 fitting against the face, the facial pressure-reducing patch for the non-invasive ventilator is securely installed on the face through the installation mechanism 3, thereby effectively preventing it from falling off due to facial shaking.

[0024] Specifically, the protective mechanism 4 includes adhesive tape 41 and waterproof protrusions 5. The adhesive tape 41 is connected to the bottom of the pressure-relieving patch body 1 via the waterproof protrusions 5, and the adhesive tape 41 adheres to the face. The waterproof protrusions 5 prevent gaps from forming between the face pressure-relieving patch and the face due to sweat and moisture, ensuring a tight fit. Specifically, the waterproof protrusions 5 have the same shape as the pressure-relieving patch body 1, and the end of the waterproof protrusions 5 facing the pressure-relieving patch body 1 has several evenly distributed posts 6. The side of the pressure-relieving patch body 1 facing the waterproof protrusions 5 has several circular grooves 7 aligned with the posts 6. The waterproof protrusions 5 are fixedly connected to the pressure-relieving patch body 1 by inserting the posts 6 into the circular grooves 7.

The side of the pressure-relieving patch body 1 facing the adhesive tape 41 has a square groove 44 aligned with the square block 42. During installation, the square block 43 presses against the corresponding waterproof protrusion 5 and inserts into the square groove 44. By setting the recessed block 42, the square block 43, and the square groove 44, the connection between the waterproof protrusion 5 and the pressure-relieving patch body 1 is further strengthened, enhancing the overall structural stability and improving the tightness of the fit to the face.

[0026] See Figure 3 and Figure 4 The installation mechanism 3 includes two sets of installation components installed on opposite sides of the protective cloth 2.
