Description

Technical Field

[0001] This utility model relates to a breathing mask, specifically a novel non-invasive breathing mask. Background Technology

[0002] Non-invasive ventilator masks are common medical devices. To ensure a tight fit, the mask is secured to the patient's face with straps to prevent air leakage caused by insufficient contact with the patient's skin.

[0003] For some critically ill patients who require nasogastric feeding, the feeding tube is inserted through the vent on the face mask. However, because of the insertion of the feeding tube, the face mask cannot be sealed, and the non-invasive ventilator will issue a warning about a leak in the face mask.

[0004] Therefore, a special mask is needed for nasogastric tubes to ensure that the seal of the mask is not compromised after the nasogastric tube is placed. Utility Model Content

[0005] The purpose of this invention is to provide a novel non-invasive breathing mask to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel non-invasive breathing mask, including a nasogastric tube and a mask, wherein the mask has a threaded hole for threaded connection of an oxygen tube elbow connector;

[0007] The mask has a receiving hole that communicates with the screw hole, and a C-shaped rubber buckle that can be wrapped around the outside of the nasogastric tube is inserted into the receiving hole.

[0008] The C-shaped rubber buckle is deformed by the oxygen tube elbow connector to lock the nasogastric tube.

[0009] Preferably, the C-shaped rubber buckle is inserted into the slot opened in the inner wall of the receiving hole by a protruding key fixed on its outer wall for limiting its position.

[0010] Preferably, the inner wall of the C-shaped rubber buckle is provided with a hollow air bladder, and the outer side of the air bladder has a semi-circular structure.

[0011] Preferably, the C-shaped rubber buckle is fixedly provided with a compression airbag on the side facing the screw hole;

[0012] The compression airbag has an arc-shaped structure, with its arc apex extending into the screw hole;

[0013] The compression airbag is connected to the airbag component.

[0014] Preferably, the port of the mask is fixedly provided with an inflatable airbag component, and an inflation tube communicating with the inflatable airbag component is fixedly installed on the mask.

[0015] Preferably, a pressure gauge is fixedly installed on the mask, and the pressure gauge is used to detect the air pressure inside the inflatable airbag.

[0016] Preferably, the port of the mask is fixedly provided with a shape memory alloy sheet, one end of which is connected to the inner wall of the inflatable airbag.

[0017] In the above technical solution, the present invention provides a novel non-invasive breathing mask with the following beneficial effects: a C-shaped rubber buckle is used to hold the nasogastric tube on the outside, and then inserted into the receiving hole. Subsequently, the oxygen tube elbow connector is threaded onto the screw hole. The installed oxygen tube elbow connector squeezes the C-shaped rubber buckle to deform and squeeze the nasogastric tube, thereby making the surfaces of each joint fit together to ensure sealing.

[0018] Secondly, a shape memory alloy sheet is added inside the inflatable airbag component. By swinging the shape of the shape memory alloy sheet, the radius of the inflatable airbag component can be changed to make it into a circle, thus adapting to the mask coverage needs of different patients.

[0019] Furthermore, the added pressure gauge can detect whether the inflatable airbag components and inflation tube are leaking, providing visual monitoring. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown, a novel non-invasive breathing mask includes a nasogastric tube 1 and a mask 2, wherein the mask 2 has a threaded hole 21 for threaded connection of an oxygen tube elbow connector 3.

[0029] The mask 2 has a receiving hole 4 that communicates with the screw hole 21. A C-shaped rubber buckle 5 that can be wrapped around the outside of the nasal feeding tube 1 is inserted into the receiving hole 4.

[0030] The C-type rubber buckle 5 is deformed by the oxygen tube elbow connector 3 to lock the nasogastric tube 1.

[0031] Specifically, in the above embodiment, the C-shaped rubber buckle 5 is inserted into the slot opened in the inner wall of the receiving hole 4 by the protruding key 51 fixedly provided on its outer wall, thereby preventing the C-shaped rubber buckle 5 from moving axially along the receiving hole 4, so as to achieve the purpose of positioning.

[0032] In the above technology, a C-shaped rubber buckle 5 is used to hold the nasogastric tube 1 on the outside, and then inserted into the receiving hole 4. Subsequently, the oxygen tube elbow connector 3 is threaded onto the screw hole 21. The installed oxygen tube elbow connector 3 squeezes the C-shaped rubber buckle 5 to deform and squeeze the nasogastric tube 1, so that the surfaces of each joint fit together to ensure sealing.

[0033] As a further embodiment of this utility model, the inner wall of the C-shaped rubber buckle 5 is provided with a hollow airbag 53, and the outer side of the airbag 53 is a semi-circular structure.

[0034] Specifically, in the above embodiment, when the oxygen tube elbow connector 3 is squeezed and the C-shaped rubber buckle 5 is deformed, the air bladder 53 will deform due to the opposite force applied by the nasogastric tube 1, thereby fitting to meet the needs of fixing nasogastric tubes of different diameters.

[0035] As another embodiment further provided by this utility model, combined with Figure 4 As shown, a compression airbag 52 is fixedly installed on the side of the C-type rubber buckle 5 facing the screw hole 21;

[0036] The compression airbag 52 has an arc-shaped structure, and its arc apex extends into the screw hole 21;

[0037] The compression airbag 52 is connected to the airbag component 53.

[0038] Specifically, in the embodiment, when the oxygen tube elbow connector 3 is squeezed, the C-shaped rubber buckle 5 will cause the compression airbag 52 to contract to the surface of the C-shaped rubber buckle 5, and the gas inside the compression airbag 52 will enter the airbag 53, thereby causing the airbag 53 to expand. The expanded airbag 53 will be deformed by the opposite force applied by the nasogastric tube 1, thereby fitting to meet the needs of fixing nasogastric tubes of different diameters.

[0039] As another embodiment further provided by this utility model, combined with Figure 4 As shown, an inflatable airbag component 6 is fixedly installed at the port of the mask 2, and an inflation tube 61 communicating with the inflatable airbag component 6 is fixedly installed on the mask 2. A pressure gauge 7 is fixedly installed on the mask 2, which is used to detect the air pressure inside the inflatable airbag component 6.

[0040] Specifically, by removing the cap on the inflation tube 61, the inflatable airbag component 6 can be inflated using a syringe, causing it to expand. A pressure gauge 7 can then be used to check for leaks between the inflatable airbag component 6 and the inflation tube 61, providing visual monitoring.

[0041] As another embodiment further provided by this utility model, combined with Figure 4 As shown, a shape memory alloy sheet 8 is fixedly installed at the port of the mask 2, with one end connected to the inner wall of the inflatable airbag component 6.

[0042] Specifically, a shape memory alloy sheet 8 is added inside the inflatable airbag component 6. By swinging the shape of the shape memory alloy sheet 8, the radius of the inflatable airbag component 6 can be changed to make it into a circle, thereby adapting to the coverage needs of different patients' masks 2.

[0043] Furthermore, the oscillating memory alloy sheet 8 in the embodiment has an arc-shaped structure, and its arc angle can change as the inflatable airbag component 6 expands.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
