Description

Technical Field

[0001] This invention relates to the field of anesthesia mask technology, specifically to an anesthesia mask gastric tube fixation device to prevent air leakage. Background Technology

[0002] For patients requiring general anesthesia who have had a nasogastric tube inserted before gastrointestinal surgery, when positive pressure ventilation is performed using an anesthesia mask after the administration of muscle relaxants and before endotracheal intubation, the anesthesia mask is placed over the patient's mouth and nose, with the nasogastric tube passing underneath. Due to the presence of the nasogastric tube, the anesthesia mask cannot properly fit the patient's mouth and face, resulting in air leakage and insufficient oxygen supply. Furthermore, the presence of the nasogastric tube, which is embedded between the anesthesia mask and the face, leaves large gaps on both sides, preventing a proper fit and further contributing to air leakage and insufficient oxygen supply.

[0003] In existing technologies, while creating a hole in the mask to puncture the gastric tube can solve the sealing problem between the gastric tube and the mask, separating the gastric tube from the negative pressure suction bulb and then pulling the gastric tube out through the hole requires complicated operations that can easily lead to leakage of gastric contents and contamination. In addition, moving the mask may pull out the gastric tube, or adding a gap for the gastric tube to the bottom side of the mask alters the structure of the mask. Although this design can achieve a sealing effect, the gap left in the mask becomes a leak point when the gastric tube is not in use.

[0004] Therefore, we propose an anesthesia mask anti-leakage gastric tube fixation device to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an anesthesia mask anti-leakage gastric tube fixation device to solve the problem mentioned in the background art that the existing anesthesia masks on the market are prone to leakage when the mask and gastric tube are used at the same time because the gastric tube cannot fit well with the patient's mouth and face.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anesthesia mask gastric tube fixation device, comprising a mask body, an air inlet pipe disposed on the mask body, and an air delivery pipe connected to the air inlet pipe. The mask body is provided with a fixing structure, and a first through groove is formed on the surface of the mask body. A sealing plate is rotatably disposed in the mask body. The closure and opening of the first through groove can be controlled by rotating the sealing plate, thereby facilitating the insertion or removal of the gastric tube from the first through groove.

[0007] As a preferred embodiment of the present invention, the air intake pipe has an internal threaded groove, the air intake pipe is threadedly connected to the threaded connector, and the threaded connector is connected to the air supply pipe by a plug-in method.

[0008] As a preferred embodiment of the present invention, the air intake pipe has an internal threaded groove, a filter element is provided inside the air intake pipe, and an external thread is provided outside the filter element, the external thread being threadedly engaged with the internal threaded groove inside the air intake pipe.

[0009] As a preferred technical solution of the present invention, the fixing structure includes: hanging rings provided on both the left and right sides of the mask body, the hanging rings being connected to the fixing straps, the fixing straps being made of elastic material, the surface of the fixing straps being provided with anti-slip textures, and an elastic rubber ring being provided on the outer edge of the mask body, the elastic rubber ring being detachably connected to the sealing ring, thereby allowing the sealing ring to be detached and replaced.

[0010] As a preferred embodiment of the present invention, the surface of the sealing plate is provided with a second through groove. When the openings of the first through groove and the second through groove are aligned, the first through groove is opened. When the openings of the first through groove and the second through groove are misaligned, the first through groove is closed.

[0011] As a preferred embodiment of the present invention, a limiting member is provided on the inner side of the mask body. The limiting member is an arc-shaped slide rail structure, which guides the rotation of the sealing plate.

[0012] As a preferred embodiment of the present invention, a slide rail is provided at the upper end of the sealing plate, and a slide rod is slidably arranged in the slide rail. One side of the slide rod is connected to a spring, and the other side of the spring is connected to the sealing plate. The slide rod is connected to a clamping plate, and an arc-shaped groove adapted to the gastric tube is provided on the inner side of the clamping plate.

[0013] As a preferred embodiment of the present invention, the surface of the arc-shaped groove of the clamp is provided with anti-slip texture, which can increase the friction between the arc-shaped groove and the gastric tube and prevent the gastric tube from loosening relative to the arc-shaped groove.

[0014] As a preferred embodiment of the present invention, the upper end of the clamping plate is provided with a recessed groove, the surface of the recessed groove is provided with anti-slip texture, and the surface of the sealing plate is also provided with multiple recessed grooves.

[0015] As a preferred embodiment of the present invention, a sealing gasket is provided at the first through groove of the mask body, the sealing gasket is tightly attached to the surface of the sealing plate, and the sealing gasket is tough.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This anesthesia mask anti-leakage gastric tube fixator enables the anesthesia mask to be quickly combined with the gastric tube. By rotating the sealing plate so that the opening direction of the second through groove is aligned with the opening direction of the first through groove on the surface of the mask body, the gastric tube is inserted through the opening of the first through groove and the second through groove. Then, by rotating the sealing plate so that the opening directions of the first through groove and the second through groove are opposite, the sealing plate can block the first through groove, preventing the mask body from leaking air from the first through groove, which would affect the smooth progress of the anesthesia. This not only ensures stable anesthesia for the patient, but also does not affect the normal use of the gastric tube.

[0018] 2. This anesthesia mask gastric tube fixation device has good stable clamping function. Because the sliding rod and sealing plate are connected by sliding, and the sliding rod is connected to the spring, the spring can always push the sliding rod towards the opening of the second through groove, thereby driving the upper end of the sliding rod to squeeze the gastric tube, stably clamping the gastric tube and preventing the gastric tube from loosening or falling off. The area of ​​the clamp can be selected in different sizes as needed. The clamp can reduce the air leakage of the first through groove of the mask body to a certain extent. By opening a recessed groove on the surface of the clamp, it is easy to fasten the recessed groove to drive the clamp to move. Attached Figure Description

[0030] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Please see Figure 1-10 This invention provides a technical solution: an anesthesia mask gastric tube fixation device, comprising a mask body 1, an air inlet pipe 2 disposed on the mask body 1, and an air delivery pipe 4 connected to the air inlet pipe 2. The air inlet pipe 2 has an internal thread groove, and the air inlet pipe 2 is threadedly connected to a threaded connector 3. The threaded connector 3 is connected to the air delivery pipe 4 by a plug-in method. The air inlet pipe 2 has an internal thread groove, and a filter element 5 is disposed inside the air inlet pipe 2. The filter element 5 has an external thread 6 disposed outside the filter element 5. The external thread 6 is threadedly engaged with the internal thread groove inside the air inlet pipe 2. The mask body 1 is provided with a fixing structure, which includes: hanging rings 7 disposed on both the left and right sides of the mask body 1, the hanging rings 7 being connected to a fixing strap 8, the fixing strap 8 being made of elastic material, and the surface of the fixing strap 8 being provided with anti-slip texture.

[0032] The above technical solution makes the mask easy to wear. Before use, the threaded connector 3 connected to the air supply tube 4 is inserted into the air inlet tube 2. The filter element 5 is inserted into the air inlet tube 2 and screwed in, thus installing the filter element 5 in the air inlet tube 2, completing the installation of the anesthesia mask. The fixing strap 8 is pulled open to extend it, and the mask body 1 is put on the face of the patient who needs general anesthesia. The fixing strap 8 is loosened, allowing it to contract under the action of natural elastic force, so that the fixing strap 8 fits tightly against the back of the patient's head, thus fixing the mask body 1 to the patient's face.

[0033] An elastic rubber ring 9 is provided on the outer edge of the mask body 1. The elastic rubber ring 9 is connected to the sealing ring 10 in a detachable manner, so that the sealing ring 10 can be removed and replaced. A sealing gasket 21 is provided at the first through groove 11 of the mask body 1. The sealing gasket 21 is tightly attached to the surface of the sealing plate 13. The sealing gasket 21 is tough.

[0034] The above-mentioned technical solution enables the anesthesia mask to have better sealing performance. Since the human face is irregular and uneven, and the patient's body size also affects the stability of the mask body 1, that is, there is a gap between the mask body 1 and the face. By setting a sealing ring 10 on the outer edge of the mask body 1, the sealing ring 10 can fit the outer edge of the mask body 1 well with the patient's mouth and face. At the same time, the sealing pad 21 can always fit tightly against the surface of the sealing plate 13, preventing the mask body 1 from having a large gap due to the setting of the sealing plate 13, avoiding air leakage of the mask body 1, and preventing the patient from receiving sufficient oxygen supply.

[0035] The face mask body 1 has a first through groove 11 on its surface. A sealing plate 13 is rotatably disposed in the face mask body 1. The opening and closing of the first through groove 11 can be controlled by rotating the sealing plate 13, which facilitates the insertion or removal of the gastric tube 20 from the first through groove 11. A second through groove 14 is provided on the surface of the sealing plate 13. When the openings of the first through groove 11 and the second through groove 14 are aligned, the first through groove 11 is open. When the openings of the first through groove 11 and the second through groove 14 are misaligned, the first through groove 11 is closed. A limiting member 12 is provided on the inner side of the face mask body 1. The limiting member 12 is an arc-shaped slide rail structure. The limiting member 12 guides the rotation of the sealing plate 13.

[0036] The above-mentioned technical solution enables the anesthesia mask to be quickly combined with the gastric tube 20, which not only provides stable anesthesia for the patient but also does not affect the normal use of the gastric tube 20, and eliminates the need to disassemble the gastric tube 20 midway. The specific operation method is as follows: rotate the sealing plate 13 so that it rotates within the limiting member 12. The opening direction of the second through groove 14 of the rotating sealing plate 13 is consistent with the opening direction of the first through groove 11 on the surface of the mask body 1. Insert the gastric tube 20 through the opening of the first through groove 11 and the second through groove 14. Then rotate the sealing plate 13 so that the opening directions of the first through groove 11 and the second through groove 14 are opposite, so that the sealing plate 13 can block the first through groove 11 to prevent the mask body 1 from leaking air from the first through groove 11, which would affect the smooth progress of the anesthesia. Pull the fixing strap 8 to extend it, put the mask body 1 on the face of the patient who needs general anesthesia, and loosen the fixing strap 8 so that it contracts under the action of natural elastic force, so that the fixing strap 8 fits tightly against the back of the patient's head, thereby fixing the mask body 1 to the patient's face.

[0037] Further improvements include a slide rail 15 at the upper end of the sealing plate 13, a slide rod 16 slidably disposed in the slide rail 15, one side of the slide rod 16 connected to a spring 17, the other side of the spring 17 connected to the sealing plate 13, the slide rod 16 connected to a clamping plate 18, an arc-shaped groove adapted to the gastric tube 20 on the inner side of the clamping plate 18, and anti-slip texture on the surface of the arc-shaped groove of the clamping plate 18, which can increase the friction between the arc-shaped groove and the gastric tube 20 and prevent the gastric tube 20 from loosening relative to the arc-shaped groove. A recessed groove 19 is provided at the upper end of the clamping plate 18, and anti-slip texture is provided on the surface of the recessed groove 19. Multiple recessed grooves 19 are also provided on the surface of the sealing plate 13.

[0038] The above technical solution enables the sealing plate 13 to clamp the gastric tube 20 more stably. Since the sliding rod 16 is connected to the sealing plate 13 by sliding, and the sliding rod 16 is connected to the spring 17, the spring 17 can always push the sliding rod 16 toward the opening of the second through groove 14, thereby driving the upper end clamping plate 18 of the sliding rod 16 to squeeze the gastric tube 20, stably clamping the gastric tube 20 and preventing the gastric tube 20 from loosening or falling off. The area of ​​the clamping plate 18 can be selected in different sizes as needed. The clamping plate 18 can reduce the air leakage of the first through groove 11 of the mask body 1 to a certain extent. By opening a recessed groove 19 on the surface of the clamping plate 18, it is easy to fasten the recessed groove 19 to drive the clamping plate 18 to move.

[0039] Working principle: When using the anesthesia mask anti-leakage gastric tube fixation device, first insert the threaded connector 3 connected to the gas delivery tube 4 into the air inlet tube 2, then insert the filter element 5 into the air inlet tube 2 and screw it in, thus installing the filter element 5 in the air inlet tube 2, completing the installation of the anesthesia mask. Rotate the sealing plate 13 to make it rotate within the limiting member 12. The second through groove 14 of the rotating sealing plate 13 is aligned with the opening direction of the first through groove 11 on the surface of the mask body 1. The gastric tube 20 connected to the patient is then inserted through the first through groove 11 and the second through groove 14. Insert the opening, then rotate the sealing plate 13 so that the opening directions of the first through groove 11 and the second through groove 14 are opposite, so that the sealing plate 13 can block the first through groove 11 to prevent the mask body 1 from leaking air from the first through groove 11, which would affect the smooth progress of the anesthesia. Pull the fixing strap 8 to make it in the extended state, put the mask body 1 on the face of the patient who needs general anesthesia, loosen the fixing strap 8, and let it contract under the action of natural elastic force, so that the fixing strap 8 fits tightly against the back of the patient's head, thereby fixing the mask body 1 to the patient's face.

[0040] Since the slide rod 16 is connected to the sealing plate 13 by sliding, and the slide rod 16 is connected to the spring 17, the spring 17 can always push the slide rod 16 toward the opening of the second through groove 14, thereby driving the upper end clamping plate 18 of the slide rod 16 to squeeze the gastric tube 20, stably clamping the gastric tube 20 and preventing the gastric tube 20 from loosening or falling off. The area of ​​the clamping plate 18 can be selected in different sizes as needed. The clamping plate 18 can reduce the air leakage of the first through groove 11 of the mask body 1 to a certain extent. By opening a recessed groove 19 on the surface of the clamping plate 18, it is easy to fasten the recessed groove 19 to drive the clamping plate 18 to move.
