Triangular patient's face protecting film for non-invasive ventilator and designing method of triangular patient's face protecting film

Abstract

The invention provides a triangular patient's face protecting film for a non-invasive ventilator and a designing method of the triangular patient's face protecting film. On the basis of the conventional square seepage absorbing film, two semi-elliptical eye socket outlines A, a nose wing outline B and a nose bridge outline C are respectively shorn off, and the triangular patient's face protecting film can be matched with the face of a patient. The triangular patient's face protecting film is characterized by consisting of a forehead sticker (1), a nose root sticker (2) and cheek stickers (3). By using the triangular patient's face protecting film, the face of the patient can be prevented from being in direct contact with a mask, and a phenomenon that the skin of the patient is injured due to the fact that the skin of the patient is irritated to be red, the patient perspires, and condensate water is not removed timely after the ventilator is humidified is avoided. The triangular patient's face protecting film has the advantages that the triangular patient's face protecting film cannot drop easily, the sight of the patient is not blocked, and pressure on a compression face is low; the sight of the patient is good; the patient cannot have pressing sensation or feel uncomfortable; no matter whether the face of the patient is injured or not, the patient can use the triangular patient's face protecting film; and the triangular patient's face protecting film can well protect a wound surface and prevent pressure sores, and is clinically applied to a hospital of the applicant.

Description

Technical field [0001] The invention provides a non-invasive ventilator patient facial triangle protective film and a design method thereof, and relates to a medical facial protective film, particularly a preparation method of the protective film. Background technique [0002] As a skin care product, the patch is generally used for the prevention and care of pressure ulcers in clinical practice. It is attached to the long-term pressured area. There is a white sponge pad inside the patch to reduce local tissue pressure and prevent pressure ulcers. This patch This effect is also used. Another function is to change the dressing for pressure ulcers. After debridement, the wound is torn and directly attached to the wound. Aseptic operation is required. The film completely covers the wound surface. The sponge inside can absorb wound exudate and maintain the wound surface. Wet growth. [0003] A ventilator is a device that can replace, control or change a person's normal physiological b...

AI Technical Summary

Problems solved by technology

The clinically used non-invasive ventilator is to connect the ventilator to the patient through the mask. Because the patient's facial tissue is pressed by the mask for a long time, blood circulation disorder, local continuous ischemia, hypoxia, and malnutrition can easily cause soft tissue ulceration and necrosis, forming pressure sore

At present, the improved ventilator mask is basically used, and a layer of silica gel is added inside the mask to reduce oppression, but the effect is not ideal and the cost is high
