Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, in particular to a painless endoscopic oral support oxygen mask. Background Art

[0002] Painless endoscopy, also known as painless gastroscopy, is based on ordinary gastroscopy. A certain dose of short-acting anesthetic is first given intravenously to help the patient quickly enter a state of sedation and sleep, complete the gastroscopy without any consciousness, and wake up quickly after the examination. Since the patient does not feel any pain during the painless gastroscopy, it can avoid mechanical damage caused by the patient's unconscious restlessness in a painful state. It is especially suitable for patients with psychological tension and timidity.

[0003] Application No. CN202221646746.6 The utility model discloses a painless endoscopic oral oxygen mask for gastroenterology, comprising a mask and an endoscope body. The mask is provided with a notch for inserting the endoscope body, a stopper is movably provided on the mask for closing the notch, an elastic sheet is provided between the stopper and the mask, a support block is movably provided inside the mask for supporting the oral cavity, an elastic drawstring is provided between the support block and the mask, and a groove is provided on the side wall of the endoscope body to fit the stopper. The gastroenterology painless endoscopic oral oxygen mask provided by the utility model has the following features: when endoscopic observation is not required, the stopper blocks the notch in the mask under the push of the elastic sheet, preventing oxygen leakage from the through-hole; when endoscopic observation is required, the endoscope body is inserted through the through-hole in the mask. After reaching the designated position, the stopper is inserted into the groove in the endoscope body under the action of the elastic sheet, securing the endoscope body to the mask without hindering its rotation.

[0004] Based on the search of the above patents and the application of existing painless endoscopic oral support oxygen masks, it is understood that when performing a painless gastroscopy on a patient, the patient's oral position needs to be supported. However, the current oral support devices are prone to interfere with the inspection instruments, making it inconvenient for the inspection instruments to enter the patient's mouth.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a painless endoscopic oral support oxygen mask is provided to achieve a more practical purpose. Summary of the Invention

Example

[0022] As attached Figure 1 To the attached Figure 8 As shown: The present invention provides a painless endoscopic oral support oxygen mask, comprising: an oxygen shield 1; a shield sealing plate 101 is provided at the front end position of the oxygen shield 1, the middle position below the front end of the shield sealing plate 101 is fixedly connected to the middle position of the rear end of an adjustment frame 2, the interior of the adjustment frame 2 is rotatably connected to a screw member 201, the interior position of the adjustment frame 2 is slidably connected to a delivery slider 202, the top middle position of the delivery slider 202 is fixedly connected to the bottom middle position of a spacing frame 3, the interior middle position of the spacing frame 3 is rotatably connected to a bidirectional screw 301, and the left and right sides of the rear end of the spacing frame 3 are respectively slidably connected to an expansion frame 302, the two expansion frames 302 are distributed in an L shape, threaded holes are opened at the lower front end positions of the sides of the two expansion frames 302, the threaded holes of the two expansion frames 302 are designed in reverse directions, and the two expansion frames 302 are plugged into the interior position of the shield sealing plate 101.

[0023] Among them, a threaded hole is opened in the middle position of the delivery slider 202, and the screw member 201 is located in the threaded hole of the delivery slider 202, and a limiting ring 102 is respectively provided on both sides of the front end of the oxygen shield 1. The two limiting rings 102 are symmetrically designed, and a circular hole is opened at the upper position of the front end of the shield sealing plate 101, and the circular hole of the shield sealing plate 101 can be plugged with a rubber sheet. The circular hole of the shield sealing plate 101 is inserted into the surgical instrument, and the surgical instrument will be located in the internal position of the oxygen shield 1. Through the cooperation of the threads on both sides of the bidirectional screw 301 and the two expansion frames 302, the two expansion frames 302 will be adjusted in opposite directions to increase the spacing between the two expansion frames 302. At this time, the surgical instrument is located in the middle position of the two expansion frames 302 and will not interfere with the overall spacing frame 3 during the support process.

[0024] Among them, a partition is provided at the middle position of the rear end of the spacing frame 3, and the bidirectional screw 301 passes through the middle position of the partition of the spacing frame 3. The left and right sides of the bidirectional screw 301 are respectively located in the threaded holes of an expansion frame 302, and the outer positions of the rear ends of the two expansion frames 302 are respectively fixedly connected with a fan-shaped tooth frame 303. The two fan-shaped tooth frames 303 are symmetrically designed, and the outer position of each fan-shaped tooth frame 303 is provided with a tooth groove. Combined with the partition design at the position of the spacing frame 3, when the two expansion frames 302 move close to each other, the two expansion frames 302 are prevented from being in a fitting state during the approach process.

[0025] Among them, the outer side of the semicircular position of each fan-shaped gear rack 303 is slidably connected to a surrounding frame 304, and the other side positions of the two surrounding frames 304 are fixedly connected to the inner middle position of a fitting frame 305 respectively. The rear end position of each surrounding frame 304 is fixedly connected to a micro-drive motor 306, and the rotating shaft of the micro-drive motor 306 is fixedly connected to the gear part 307. The gear part 307 is located in the internal position of the surrounding frame 304, and the gear part 307 is engaged with the tooth groove position of the fan-shaped gear rack 303.

[0026] When using: Put the oxygen mask 1 on the patient's face, then tie the two limiting loops 102 with a rope, and wrap the rope around the outside of the patient's head. After the patient opens his mouth, turn the screw 201, and the screw 201 cooperates with the threaded hole of the delivery slider 202. The delivery slider 202 slides backward inside the adjustment frame 2, and the delivery slider 202 drives the spacing frame 3 to move backward as a whole. The two fitting frames 305 will be located inside the patient's mouth.

[0027] When the bidirectional screw 301 is rotated, the two expansion frames 302 will be adjusted in opposite positions through the cooperation between the threads on both sides of the bidirectional screw 301 and the two expansion frames 302, thereby increasing the distance between the two expansion frames 302. At this time, the distance between the two fitting frames 305 will be relatively increased, and the fitting frames 305 will fit the patient's mouth position to expand and support it, and ensure that the spacing frame 3 is located at the front end of the patient's mouth. Example

[0028] After starting the micro drive motor 306, the micro drive motor 306 will drive the gear part 307 to rotate, and the gear part 307 will engage with the tooth groove position of the fan-shaped gear rack 303 for transmission. The surrounding frame 304 will slide on the outer position of the fan-shaped gear rack 303, and the two fitting frames 305 will respectively adjust the arc position in combination with the fan-shaped position of the fan-shaped gear rack 303, thereby changing the fitting frame 305 to fit the patient's oral position, making it easier to support the patient's oral position at multiple angles.

[0029] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. The protection scope of the present disclosure should be based on the protection scope of the claims.
