Description

Technical Field

[0001] The utility model relates to the technical field of ventilation masks, in particular to a disposable non-invasive ventilation mask. Background Art

[0002] Severely ill patients who cannot breathe on their own often need a gastric tube placed in their stomach, through which liquid food is injected into the patient's stomach using a syringe to replenish the nutrients needed by the patient's body.

[0003] Severely ill patients who cannot breathe on their own often need ventilator-assisted breathing support. The ventilator is often connected to a non-invasive ventilation mask using a hose, and the non-invasive ventilation mask provides respiratory support to the patient. However, the non-invasive ventilation mask presses tightly against the patient's face, and the water vapor exhaled by the patient makes the inside of the non-invasive ventilation mask moist. Long-term facial compression can easily cause skin surface pressure sores such as redness, swelling, blisters or ulcers.

[0004] For some patients who need a gastric tube, because the gastric tube needs to pass between the non-invasive ventilation mask and the facial skin, there will be indentations where the gastric tube passes, which often leads to poor sealing of the non-invasive ventilation mask and air leakage.

[0005] In addition, the existing non-invasive ventilation mask straps often strangle the neck, which can easily cause skin damage on the back of the patient's neck. In severe cases, it may cause skin infection, which is not conducive to the patient's recovery. Currently, common non-invasive ventilation masks generally only support a single wearing method and cannot provide a variety of options according to the needs of patients.

[0006] The facial contours of different patients are different. Existing non-invasive ventilation masks cannot be adjusted according to the facial contours of patients so that the non-invasive ventilation masks can fit the facial skin completely, which increases the risk of pressure sores and the probability of air leakage. Therefore, it is a problem that those skilled in the art need to solve to provide a disposable non-invasive ventilation mask that increases sealing and reduces pressure sores, and that can select different straps according to the needs of patients and has a hole for gastric tube insertion.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] The present application provides a disposable non-invasive ventilation mask to solve the technical problems that the existing non-invasive ventilation mask cannot fit the facial skin completely, the sealing performance is reduced and air leakage is easy to occur, the existing non-invasive ventilation mask is pressed on the skin surface and pressure sores are easy to form, and the existing non-invasive ventilation mask cannot replace different straps according to the needs of patients. In addition, the existing non-invasive ventilation mask is not provided with a gastric tube insertion hole, and cannot simultaneously perform respiratory support therapy and supplement the patient's body with nutrients required by the patient through a gastric tube while ensuring the sealing performance. To this end, the present application provides the following specific embodiments.

[0045] This embodiment provides a disposable non-invasive ventilation mask. Figures 1 to 11 , including, a mask body 1, referring to Figure 1 The mask body 1 is configured to be made of transparent plastic. The mask body 1 made of transparent plastic does not block the patient's line of sight, making it convenient for medical staff to observe the patient's facial condition.

[0046] The mask body 1 has an arcuate surface, and the mask body 1 extends to the lower jaw. When the mask body 1 is buckled on the face, the arcuate surface allows the mask body 1 to have a certain distance from the nose tip, thereby preventing the mask body 1 from pressing on the patient's nose tip and affecting the patient's breathing.

[0047] The inner surface of the mask body 1 is attached with a first anti-pressure pad 2, referring to Figures 2 to 4 The first anti-pressure pad 2 is composed of an absorbent sponge and a silicone pad. The absorbent sponge is annular and fits the edge of the mask body 1. The silicone pad is arranged on the surface of the mask body that fits the face, so that the first anti-pressure pad 2 fits the facial skin. When the non-invasive ventilation mask is buckled on the patient's face with an elastic strap, the silicone pad directly contacts the patient's facial skin, which reduces the pain of wearing for patients who wear it for a long time and reduces the occurrence of pressure sores. The silicone pad has sufficient flexibility and can have different shrinkage amounts according to the facial contour of the patient when it fits the facial skin, thereby increasing the sealing of the mask body.

[0048] The water vapor exhaled by the patient condenses on the inner surface of the non-invasive ventilation mask, flows along the curved surface to the absorbent sponge and is absorbed by the absorbent sponge, preventing the water vapor condensed on the surface of the non-invasive ventilation mask from dripping onto the patient's face and causing discomfort to the patient.

[0049] Preferably, the upper surface of the first anti-pressure pad 2 is evenly distributed with rubber pads arranged in a dot shape, and the rubber pads are coated with an adhesive.
