Description

Technical Field

[0001] The utility model relates to the technical field of medical clinical equipment, in particular to a non-invasive ventilator mask for preventing pressure sores. Background Art

[0002] A non-invasive ventilator generally refers to a device for ventilator treatment through a nasal mask or a face mask. Since it is not necessary to intubate or tracheotomize the patient, it is easy to operate and acceptable to the patient. Moreover, it has few injuries and complications such as ventilator-associated pneumonia. It is widely used not only for the treatment of inpatients with acute or chronic respiratory failure, but also for outpatient patients with stable conditions at home, and its application at home is increasing. The ventilator realizes gas exchange through the conversion of positive pressure and negative pressure, which makes the ventilator mask must be closely attached to the patient's skin to prevent air leakage. Due to the diversity of human face sizes, the ventilator mask cannot correctly adapt to the face shapes of every patient. Therefore, air leakage may occur between the ventilator mask and the patient's face.

[0003] A three-dimensional pressure sore prevention anesthetic mask with the patent publication number of CN205659238U includes a mask body, an air inlet and an airbag. The upper side of the mask body is connected to the air inlet, and the lower side is connected to the airbag. An inflation valve is arranged on one side of the airbag, and a nasal bridge groove is arranged at the top of the airbag. The nasal bridge part of the inflated airbag is concave, which conforms to the physiological characteristics of the human face. When in use, it fully fits the human face. The pressure of the inflated airbag of the mask acts evenly on the human face, and a foam dressing and a collagen hydrocolloid are adhered to the surface to further buffer the pressure of the inflated airbag of the anesthetic mask acting on the human face. However, when the patient continuously uses the mask, the airbag body presses on the patient's facial skin for a long time, still easily causing pressure sores on the patient and increasing the patient's pain. Content of the Utility Model

[0004] The utility model aims to solve the shortcomings existing in the prior art, and provides a non-invasive ventilator mask for preventing pressure sores that can avoid pressing the patient's facial skin for a long time and does not leak air.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A non-invasive ventilator mask for preventing pressure sores includes a mask body. An air inlet is connected to the front side of the mask body, and an airbag is bonded to the periphery of the side that fits the face at the rear side. A charging and discharging tube is arranged on one side of the airbag, and a charging and discharging valve is arranged on the charging and discharging tube. The outer end of the charging and discharging tube is connected to a negative pressure charging airbag; a dressing thin plate is connected to the outer side of the airbag surface. One side of the dressing thin plate extends towards the airbag surface and is bonded to the airbag surface. The plate body of the dressing thin plate is parallel to the airbag surface at its corresponding position, and a medical adhesive layer is bonded to the outer surface of the dressing thin plate.

[0007] Preferably, when the airbag is in an uninflated state, the distance between the patch thin plate and the surface of the airbag is 0.1 - 1 mm.

[0008] Preferably, the radial cross-sectional width of the patch thin plate is 1 - 3 mm.

[0009] Preferably, a convenient tear paper is bonded to the upper surface of the medical adhesive layer.

[0010] Preferably, the patch thin plate and the airbag are integrally formed. The patch thin plate is made of medical silicone material, and the airbag is made of rubber.

[0011] Preferably, a plurality of hemispherical small convex grains are distributed on the inner side surface of the patch thin plate close to the airbag.

[0012] Preferably, the top structure of the airbag is in a shape matching the shape of the human nasal bridge.

[0013] Preferably, the air inlet and outlet pipe is connected to the airbag at the lower part of the mask.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The pressure ulcer prevention non-invasive ventilator mask of the present utility model uses an airbag in cooperation with a medical adhesive layer. When the airbag is inflated, the patch thin plate is adhered to the face, and then the air is released to reduce the inflation pressure of the airbag. When the mask is used, the patch thin plate is attached to the face through the inflated airbag, so that the adhesive layer always remains adhered and will not fall off due to reasons such as sweat, ensuring the sealing effect; that is, air leakage is avoided, and the pressure applied to the face is also prevented from being too large to cause pressure ulcers. In addition, the setting of a gap between the patch thin plate and the airbag body can ensure that the patch thin plate closely adheres to the skin while allowing for fine adjustment of the mask, making the mask more comfortable to wear.

[0019] Embodiment

[0020] Figure 1-2 The structural schematic diagram of the embodiment of the non-invasive ventilator mask for preventing pressure ulcers according to the present utility model is shown.

[0021] A non-invasive ventilator mask for preventing pressure ulcers in this embodiment includes a mask body 1. An air inlet 2 is connected to the front side of the mask body 1. An airbag 3 is bonded to the periphery of the side that fits the face at the rear side. A charging and discharging tube 40 is provided on one side of the airbag 3. A charging and discharging valve 42 is provided on the charging and discharging tube 40. The outer end of the charging and discharging tube 40 is connected to a negative pressure charging airbag 41. An application thin plate 5 is connected to the outer surface of the airbag 3. One side of the application thin plate 5 extends toward the surface of the airbag 3 and is bonded to the surface of the airbag 3. The plate body of the application thin plate 5 is parallel to the surface of the airbag 3 at its corresponding position, and two curved surfaces are parallel as visible in the cross-sectional view. A medical adhesive layer 6 is bonded to the outer surface of the application thin plate 5. When in use, a certain amount of air is inflated by pressing the negative pressure charging airbag, so that the airbag expands and presses the application thin plate tightly against the face; when deflation is required, the deflation button of the charging and discharging valve is opened to deflate the airbag.

[0022] When the airbag is in an uninflated state, the distance between the application thin plate 5 and the surface of the airbag 3 is 0.1 - 1 mm. The radial cross-sectional width of the application thin plate 5 is 1 - 3 mm.

[0023] A convenient tearing paper 60 is bonded to the upper surface of the medical adhesive layer 6. When in use, the convenient tearing paper is directly torn off for use.

[0024] The application thin plate 5 and the airbag 3 are integrally formed. The application thin plate 5 is made of medical silicone material, and the airbag 3 is made of rubber. In addition, a layer of collagen hydrocolloid is adhered to the surface of the airbag 5, and the collagen hydrocolloid promotes local skin blood circulation and avoids pressure ulcers.

[0025] A plurality of hemispherical small convex particles 50 are distributed on the inner side surface of the application thin plate 5 close to the airbag 3; when the airbag 3 is inflated, the airbag presses against the small convex particles to press the application thin plate tightly against the skin, ensuring that the application thin plate is completely adhered to the skin.

[0026] The top structure of the airbag 5 is in a shape matching the shape of the human nose bridge. The nose bridge part of the inflated airbag is concave, which conforms to the physiological characteristics of the human face and fully fits the human face during use.

[0027] To prevent the air charging and discharging tube 40 device from directly hanging on the human face, the air charging and discharging tube 40 is connected to the airbag 3 at the lower part of the mask 1.

[0028] When the non-invasive ventilator mask for preventing pressure sores of the present utility model is in use, tear off the release paper on the surface of the medical adhesive layer, attach the mask to the human face, and then inflate it by pressing the negative pressure inflation airbag. After inflation, the airbag body bulges and the valve is closed. While the airbag bulges, the dressing thin plate is tightly adhered to the face. After the dressing thin plate is firmly adhered, open the air charging and discharging valve to perform a small amount of deflation to reduce the pressure of the airbag on the facial skin.
