In addition, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] As shown in Figure 1 The present application provides a non-invasive respirator mask for preventing pressure injury, which comprises a mask body 100, a pressure relief dressing pad 200 and a mask fixing piece 300; the mask body 100 is provided with a raised nasal cavity part 110, and the nasal cavity part 110 is filled with a pressure relief dressing layer 120 at the nasal root position area in contact with the patient; the mask body is provided with the pressure relief dressing pad 200 on the contour surface in contact with the patient, and the mask fixing piece 300 is used to fix the mask body 100 to the facial area of the patient.

[0026] The mask body 100 of the pressure injury prevention non-invasive ventilator mask is the main component of the pressure injury prevention non-invasive ventilator mask, usually made of soft material such as silicone, etc. It covers the nose and mouth of the user, used to connect the breathing equipment and the user's respiratory system. The mask body 100 needs to have good sealing and comfort to ensure the effectiveness of the respiratory treatment and the user's experience. The mask body 100 is usually designed to be adjustable to adapt to the face shape and size of different users. It is also equipped with a headband or fixing band to ensure that the mask can tightly fit on the user's face to prevent leakage of oxygen or therapeutic gas. When using the pressure injury prevention non-invasive ventilator mask, the user needs to choose the appropriate mask type and size according to their own needs and the doctor's advice to ensure that the mask can provide the best respiratory treatment effect. At the same time, the user also needs to pay attention to the cleaning and maintenance of the mask to avoid bacterial growth and mask aging, etc. Specifically, the mask body 100 can mainly include a lower mask and a forehead pad, wherein the lower mask is used to cover the oral and nasal areas of the patient, and the forehead pad is used to apply a certain pressure to the upper half of the lower mask, so as to maintain the tight contact between the upper half of the lower mask and the patient's skin, and maintain a certain sealing performance.

[0027] The pressure relief dressing pad 200 is a dressing specially used to cover and protect the skin under the pressure injury prevention non-invasive ventilator mask. Because the pressure injury prevention non-invasive ventilator mask will produce a certain pressure and friction on the skin during use, it is easy to cause skin damage and discomfort, so a mask dressing is needed to protect the skin. The pressure relief dressing used here is usually soft, comfortable, breathable, etc., which can effectively reduce the pressure and friction of the mask on the skin and prevent skin damage. At the same time, it can also absorb the sweat and sebum on the surface of the skin, keep the skin dry and clean, and reduce the risk of bacterial growth and infection. Common pressure relief dressings include hydrocolloid dressings, foam dressings, and gauze dressings, etc. Among them, the hydrocolloid dressing is widely used in mask dressings due to its good breathability, moisture absorption and pressure relief effect. In summary, the pressure relief dressing pad 200 is an important auxiliary material for protecting the skin under the pressure injury prevention non-invasive ventilator mask, which can reduce the pressure and friction of the mask on the skin, keep the skin dry and clean, reduce the risk of skin damage and infection, and improve the user's comfort and treatment effect. Further, the pressure relief dressing pad 200 is arranged on the contact contour surface of the mask body and the patient, so that the pressure relief dressing pad is arranged on the entire contact surface between the mask body and the patient, thereby reducing the pressure on the patient's skin when wearing the pressure injury prevention non-invasive ventilator mask and reducing the risk of pressure ulcers.

[0028] The mask fixing part 300 is a component for fixing the mask, and its main function is to stably fix the mask on the head to prevent it from falling off or shifting during use. The design of the mask fixing part 300 can vary depending on different types of masks and purposes. For example, some mask fixing parts 300 use adjustable straps, elastic bands, Velcro, etc. to adapt to users of different head shapes and sizes.

[0029] In order to adapt to the shape of the patient's nose, a raised nasal cavity part 110 is provided on the mask body 100, which has a similar shape to the nose. Simply put, the raised nasal cavity part 110 is a raised cavity with a shape similar to that of the nose. The nasal root position area of the nasal cavity part 110 is a certain shaped area centered on the nasal root position in the nasal cavity part 110. The shape and size of this area can be adjusted according to actual conditions. For example, it can be set as a circular area or a rectangular area centered on the nasal root position, and the area size can be relatively small. In the case of a rectangular area, the length can be 4-6 cm, and the width can be 1-3 cm. The preferred length of the rectangular area is 5 cm, and the width of the rectangular area is 1.5 cm, which is more suitable for the size of the area where the mask body presses the patient's nasal root position in general, in order to fill the pressure relief dressing layer 120 specifically. The pressure relief dressing layer 120 is provided inside the mask body, i.e. on the side that contacts the patient (the inside is shown by the dashed line). Figure 1 In clinical practice, the applicant found that in addition to paying attention to the profile of the mask pressing the patient's skin, the presence of the forehead pad in the mask body 100 during the actual application of the non-invasive ventilator mask for pressure ulcer prevention makes the nasal root position prone to pressing the patient's skin. Therefore, the pressure relief dressing layer 120 is filled at the nasal root here.

[0030] The non-invasive ventilator mask for preventing pressure ulcers of the present application comprises a mask body 100, a pressure relief dressing pad 200, and a mask fixing part 300. The mask body 100 is provided with a raised nasal cavity part 110, and the nasal root position area of the nasal cavity part 110 is filled with a pressure relief dressing layer 120. The mask body and the patient's contact profile are provided with a pressure relief dressing pad 200, and the mask fixing part 300 is used to fix the mask body 100 to the patient's facial area. In addition to paying attention to the profile of the mask pressing the patient's skin, the non-invasive ventilator mask for preventing pressure ulcers also considers the situation that the presence of the forehead pad in the mask body 100 during the actual application of the non-invasive ventilator mask for preventing pressure ulcers makes the nasal root position prone to pressing the patient's skin. The pressure relief dressing layer 120 is provided on the nasal root area and the patient's contact profile, so that the pressure of the non-invasive ventilator mask on the patient's skin during actual wearing can be reduced, thereby significantly reducing the phenomenon of pressure sores.

[0031] In one embodiment, the non-invasive ventilator mask for preventing pressure injury described above further comprises a first pressure sensing component for monitoring the pressure at the nasal root location area.

[0032] The first pressure sensing component plays a crucial role in the non-invasive ventilator mask for preventing pressure injury. This component is usually located at the nasal root location area of the mask and can monitor the pressure changes in this area in real time. By sensing and measuring the pressure, the first pressure sensing component can help doctors and nurses understand the fit of the mask on the patient's face and the pressure distribution inside the mask. This is crucial for assessing the comfort of wearing the mask, preventing mask leaks, and ensuring that the patient receives stable and effective oxygen supply. Specifically, the working principle of the first pressure sensing component may involve various sensor technologies, such as pressure sensors, pressure-sensitive resistors, etc. When the mask is fitted to the patient's face, the sensor can sense the pressure changes at the nasal root location area and convert this information into an electrical signal, which can then be processed and analyzed to provide real-time feedback on the pressure status of the mask. In practical applications, the data of the first pressure sensing component can be connected to the ventilator to achieve real-time monitoring and recording. Doctors and nurses can adjust the wearing method of the mask, replace the appropriate mask size or adjust the parameters of the ventilator according to these data to ensure that the patient receives the best respiratory treatment effect.

[0033] In one embodiment, the non-invasive ventilator mask for preventing pressure injury described above further comprises a second pressure sensing component for monitoring the pressure at the contact point between the mask fixing part 300 and the mask main body 100.

[0034] The second pressure sensing component in the non-invasive ventilator mask for preventing pressure ulcers is used to monitor the pressure at the contact points between the mask fasteners 300 and the mask body 100. This design aims to ensure that the mask is fixed stably and does not cause discomfort to the patient. Mask fasteners 300 are usually the parts used to ensure that the mask fits closely and comfortably on the patient's face. They may include headbands, elastic bands or other fixing devices to secure the mask body 100 in place. However, if the pressure exerted by the fasteners is too high, it may cause the patient to feel uncomfortable or painful, and even cause skin damage. Therefore, it is crucial to monitor the pressure at these contact points. The second pressure sensing component is usually located at the key points where the mask fasteners 300 contact the mask body 100. It can be a small, thin pressure sensor that can accurately measure the pressure exerted on the skin. These sensors can monitor the changes in pressure in real time and transmit the data to the connected devices, such as ventilators or monitors. By monitoring the pressure at these contact points, doctors and nurses can understand the fixation of the mask and whether the fasteners cause discomfort to the patient. If the pressure is found to be too high, they can take appropriate measures, such as adjusting the tightness of the fasteners, replacing different types of fasteners or adjusting the wearing position of the mask, to ensure that the mask is fixed stably and comfortably.

[0035] In one embodiment, the non-invasive ventilator mask for preventing pressure ulcers further comprises a pressure display component connected to the first pressure sensing component.

[0036] Specifically, the first pressure sensing component is responsible for monitoring the pressure changes inside the mask and transmitting these data to the pressure display component. The pressure display component is usually an electronic display screen that can visually display the pressure at the nasal root position area to prompt medical staff to adjust the tightness of the mask fasteners 300 and alleviate the patient's pressure ulcer phenomenon.

[0037] As shown in Figure 2 In one embodiment, the non-invasive ventilator mask for preventing pressure ulcers further comprises a breathing tube 400, a breathing hole 130 is opened on the mask body 100, and the breathing tube 400 is connected to the breathing hole 130; a gastric tube hole 140 is also opened on the mask body 100.

[0038] The structural design of the non-invasive ventilator mask for preventing pressure injuries is crucial for its functionality and comfort of use. The addition of designs such as the breathing tube 400, breathing hole 130, and gastric tube hole 140 in the mask are aimed at meeting the different treatment needs of patients and improving treatment outcomes. First, the breathing tube 400 is an important channel that connects the mask to the oxygen source or other respiratory assistance devices. It ensures that oxygen or therapeutic gases can flow smoothly into the mask, providing the necessary respiratory support for the patient. The breathing hole 130 is a direct communication channel between the inside of the mask and the external environment, allowing the patient to breathe naturally through the mask when needed. The gastric tube hole 140 is designed for patients who need to receive gastric tube feeding or gastric fluid drainage. Through this hole, medical personnel can easily insert a gastric tube to achieve the patient's nutritional supply or medical operation. The design of these holes and tubes needs to consider the sealing, comfort, and safety of the mask. At the same time, their position and size need to be determined according to the specific needs of the patient and the overall design of the mask. In general, the design of the breathing tube 400, breathing hole 130, and gastric tube hole 140 in the non-invasive ventilator mask for preventing pressure injuries is aimed at improving the functionality and applicability of the mask to meet the treatment needs of different patients. These designs make the non-invasive ventilator mask for preventing pressure injuries more comprehensive in meeting the respiratory and medical needs of patients, improving treatment outcomes and patient comfort.

[0039] In practical applications, the breathing hole 130 and the gastric tube hole 140 are on the same horizontal line, which facilitates the insertion of the gastric tube into the patient in clinical practice. Further, the gastric tube hole 140 is inclined at a preset angle towards the nasal cavity position. This inclined design can avoid the gastric tube from pressing the breathing tube 400 during insertion. The preset angle is a pre-set angle, which can be an angle in the range of 25° to 35°, and preferably 30°.

[0040] In one embodiment, a valve with adjustable diameter is provided in the gastric tube hole 140.

[0041] Adjustable diameter means that the diameter of the inserted tube (gastric tube) can be adjusted. Specifically, the valve with adjustable diameter provided in the gastric tube hole 140 allows the entire non-invasive ventilator mask for preventing pressure injuries to be compatible with gastric tubes of various diameters, improving the applicability of the mask. In addition, the provision of the valve can maintain a certain sealing of the mask after the gastric tube is inserted, ensuring stable extracorporeal respiratory support for the patient.

[0042] Any technical features in the above embodiments can be combined, and for the sake of brevity, not all possible combinations are described above, however, as long as the combinations do not conflict with each other, they should be considered to be within the scope of the present disclosure.

[0043] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
