Description

Technical Field

[0001] This utility model relates to the field of oxygen masks, and more particularly to a high-pressure oxygen mask for indwelling gastric tubes. Background Technology

[0002] Oxygen masks are devices that transfer oxygen from a storage tank to the lungs. There are mainly two types: medical oxygen masks and civilian aviation oxygen masks. They play an important role in assisting in the treatment of diseases and protecting the safety of flight attendants.

[0003] Existing patent, publication number CN214550591U, discloses a high-pressure oxygen mask for indwelling gastric tubes, including a mask shell, a breathing tube, and a mask pad. The mask shell has a gastric tube connector protruding from its outer surface. The gastric tube connector has a plug hole with a diameter larger than the diameter of the gastric tube's tail end. The plug hole is inverted conical in shape, and a sealing plug, shaped like an inverted frustum, is inserted into the plug hole. The sealing plug has a gastric tube opening for the gastric tube to pass through. This invention's high-pressure oxygen mask for indwelling gastric tubes enhances the airtightness of the oxygen mask when using a gastric tube, preventing hypoxia caused by insufficient oxygen ventilation in patients. It also saves medical resources, reduces surgical costs, and meets surgical needs.

[0004] However, in practical application, the inventors believe that the following defects exist:

[0005] Disadvantages: Although the mask has a gastric tube in place during actual use, it is inconvenient to remove and install the gastric tube as needed. As a result, it is impossible to maintain a tight seal between the gastric tube and the mask after installation, which may lead to leakage during oxygen delivery. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of disassembling and assembling the gastric tube during use, and the inability to improve the seal between the mask and the gastric tube. Therefore, this invention proposes a high-pressure oxygen mask for indwelling gastric tubes.

[0007] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0008] A high-pressure oxygen mask for inserting a gastric tube includes a mask body, the top of which is connected to a vertical tube, a gastric tube is inserted into the vertical tube, a cover is fitted over the surface of the gastric tube, the inner wall of the cover is threadedly connected to the surface of the vertical tube, a buffer spring is fixedly installed on the inner top wall of the cover, a compression ring is fixedly installed at the bottom of the buffer spring, and a conical ring is fixedly installed on one side of the inner top wall of the cover.

[0009] A screw is inserted into one side of the vertical tube. A turntable is fixedly installed at one end of the screw outside the vertical tube. One end of the screw passes through the vertical tube and extends into the interior of the vertical tube to contact the surface of the gastric tube. An air inlet pipe is connected to one side of the top of the cover.

[0010] The designed cover, along with a buffer spring, compression ring, conical ring, and screw, facilitates the assembly and disassembly of the gastric tube during use. It also maintains the airtightness of the connection, preventing leakage due to poor airtightness and ensuring the proper use of the face mask afterwards.

[0011] Preferably, the conical ring is located inside the compression ring and is made of rubber. The surface of the compression ring is slidably connected to one side of the inner wall of the cover. The conical ring is located inside the compression ring. When the compression ring moves, it can compress the surface of the conical ring. Because the conical ring is made of rubber, it can fit the gastric tube after being compressed, while also avoiding damage to the gastric tube.

[0012] Preferably, the cover has a hole for the gastric tube to pass through, and both the compression ring and the conical ring are located on the surface of the gastric tube. The inner ring of the compression ring is slidably connected to the surface of the gastric tube, and the inner wall of the conical ring is in contact with the surface of the gastric tube. The inner ring of the compression ring is slidably connected to the surface of the gastric tube to prevent the position of the compression ring from shifting when it moves.

[0013] Preferably, a silicone ring is fixedly installed on the inner wall of the tube hole on the cover. The silicone ring has a semi-circular cross-section, and the inner wall of the silicone ring fits against the surface of the gastric tube. The silicone ring prevents gaps between the cover and the gastric tube during installation, further increasing the sealing between the cover and the gastric tube.

[0014] Preferably, an anti-slip strip is fixedly installed on the surface of the turntable, and the surface of the anti-slip strip is provided with anti-slip texture. The turntable and anti-slip strip increase the friction of the turntable surface during use, making it easier to rotate the screw through the turntable.

[0015] Preferably, the vertical tube has a screw hole for the screw rod to pass through, and the screw hole is threadedly connected to the screw rod. The screw hole and screw rod facilitate the initial positioning of the gastric tube inside the vertical tube during use, and facilitate the subsequent tightening and sealing of the gastric tube.

[0016] Preferably, a silicone ring is fixedly installed at the bottom of the cover, and the lower surface of the silicone ring is set to be smooth. The silicone ring increases the fit between the cover and the face during use.

[0017] Preferably, the surface of the air inlet pipe is connected to a valve, one side of which is fixedly connected to one side of the mask. The air inlet pipe is set to an inclined state. The air inlet pipe and valve can control the air intake of the mask in real time during use. Patients or medical staff can adjust it according to the actual situation without adjusting the machine, which improves the ease of use of the mask.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The high-pressure oxygen mask for the indwelling gastric tube, through the designed cover, in conjunction with the buffer spring, compression ring, conical ring and screw, facilitates the disassembly and assembly of the gastric tube during use, while also maintaining the airtightness of the connection to prevent leakage due to poor airtightness during use, thus facilitating the normal use of the mask.

[0020] 2. The high-pressure oxygen mask with indwelling gastric tube can control the air intake in real time during use through the set air inlet pipe and valve. Patients or medical staff can adjust it according to the actual situation without adjusting the machine, which improves the ease of use of the mask. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A high-pressure oxygen mask for inserting a gastric tube includes a mask body 1. A vertical tube 2 is connected to the top of the mask body 1. A gastric tube 3 is inserted inside the vertical tube 2. A cover 4 is fitted over the surface of the gastric tube 3. The inner wall of the cover 4 is threadedly connected to the surface of the vertical tube 2. A buffer spring 5 is fixedly installed on the inner top wall of the cover 4. A compression ring 6 is fixedly installed at the bottom of the buffer spring 5. A conical ring 7 is fixedly installed on one side of the inner top wall of the cover 4. The conical ring 7 is located inside the compression ring 6 and is made of rubber. The surface of the compression ring 6 is slidably connected to one side of the inner wall of the cover 4. The conical ring 7, located inside the compression ring 6, can compress the surface of the conical ring 7 when the compression ring 6 moves. The conical ring 7, being made of rubber, is subjected to... After compression, it fits snugly against the gastric tube 3, while also preventing damage to the gastric tube 3. The cover 4 has a hole for the gastric tube 3 to pass through. The compression ring 6 and the conical ring 7 are both located on the surface of the gastric tube 3. The inner ring of the compression ring 6 is slidably connected to the surface of the gastric tube 3, and the inner wall of the conical ring 7 is fitted against the surface of the gastric tube 3. The slidable connection between the inner ring of the compression ring 6 and the surface of the gastric tube 3 prevents the compression ring 6 from shifting its position when it moves. A silicone ring 11 is fixedly installed on the inner wall of the hole on the cover 4. The silicone ring 11 has a semi-circular cross-section, and the inner wall of the silicone ring 11 is fitted against the surface of the gastric tube 3. The silicone ring 11 prevents gaps between the cover 4 and the gastric tube 3 during installation, further increasing the sealing between the cover 4 and the gastric tube 3.

[0030] A screw 8 is inserted into one side of the vertical tube 2. A turntable 9 is fixedly installed at one end of the screw 8 outside the vertical tube 2. One end of the screw 8 passes through the vertical tube 2 and extends into the interior of the vertical tube 2 to contact the surface of the gastric tube 3. An air inlet pipe 10 is connected to one side of the top of the cover 1. An anti-slip strip 12 is fixedly installed on the surface of the turntable 9. The surface of the anti-slip strip 12 has anti-slip texture. The turntable 9 and the anti-slip strip 12 increase the friction of the surface of the turntable 9 during use, making it easier to rotate the screw 8 through the turntable 9. A screw hole is opened on the vertical tube 2 for the screw 8 to pass through, and the screw hole is threaded to the screw 8. The screw hole and the screw 8 facilitate the initial positioning of the gastric tube 3 inside the vertical tube 2 during use, making it easier to tighten and seal the gastric tube 3 later. A silicone ring 13 is fixedly installed at the bottom of the cover 1. The lower surface of the silicone ring 13 is set to be smooth. The silicone ring 13 increases the fit between the cover 1 and the face during use.

[0031] The cover 4, in conjunction with the buffer spring 5, compression ring 6, conical ring 7, and screw 8, facilitates the assembly and disassembly of the gastric tube 3 during use, while maintaining the airtightness of the connection to prevent leakage and ensure proper use of the mask. A valve 14 is connected to the surface of the air inlet pipe 10, with one side of the valve 14 fixedly connected to one side of the cover 1. The air inlet pipe 10 is tilted. The air inlet pipe 10 and valve 14 allow for real-time control of the air intake of the cover 1 during use. Patients or medical staff can adjust these parameters as needed without requiring machine adjustments, thus improving the ease of use of the mask.

[0032] Specifically, the working principle and operation method of this utility model are as follows:

[0033] When positioning the gastric tube 3 is required, insert the gastric tube 3 into the interior of the vertical tube 2, and then tighten the screw 8 on the turntable 9 to initially position the gastric tube 3. Then, put the cover 4 on the surface of the gastric tube 3 and tighten the cover 4 to make the cover 4 threadedly connected to the vertical tube 2. During the tightening process of the cover 4, the top of the vertical tube 2 presses against the compression ring 6, and then the compression ring 6 moves upward. The inner wall of the compression ring 6 presses against the surface of the conical ring 7. The higher the position of the compression ring 6, the greater the force on the surface of the conical ring 7, thereby increasing the fit between the conical ring 7 and the surface of the gastric tube 3. At the same time, the inner wall of the silicone ring 11 fits against the surface of the gastric tube 3, which increases the airtightness between the cover 1 and the gastric tube 3 while the gastric tube 3 is tightened and installed.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
