[0021] The following further describes in detail the above and other technical features and advantages of the present utility model with reference to the accompanying drawings.

[0022] Embodiment 1

[0023] As Figure 1 shown, Figure 1 is a structural view of the intubation - type anesthesia mask for painless gastroscopy.

[0024] The intubation - type anesthesia mask for painless gastroscopy of the present utility model includes a mask body 1. A fixing hole is provided on the mask body 1. An oral pressure tube 2 is fixedly arranged in the fixing hole. The oral pressure tube 2 is hollow - arranged, and the outer wall of the oral pressure tube 2 is sealingly connected to the mask body 1. The oral pressure tube 2 has a certain extension length on both the inner and outer sides of the mask body 1. The end of the oral pressure tube 2 arranged on the inner side of the mask body 1 can be arranged in the patient's oral cavity. The oral pressure tube 2 is used to open the patient's lips and teeth to provide an operation space, so that the gastroscope intubation can enter the oral cavity of the anesthetized patient through the inside of the oral pressure tube 2 and be inserted. At the same time, the patient's lips and teeth are wrapped around the outside of the oral pressure tube 2, so that the space between the inner surface of the mask body 1 and the patient's face has a certain sealing effect at the position of the oral pressure tube 2.

[0025] A sealing part is arranged inside the oral pressure tube 2. The sealing part is used to seal the gap between the gastroscope intubation and the oral pressure tube 2, thereby reducing the gas leaked from the inside of the oral pressure tube 2 and avoiding affecting pressurized oxygen supply.

[0026] Fixing straps 3 are arranged on both sides of the mask body 1. By winding the fixing straps 3 around the patient's head, the mask body 1 is fixed at the patient's mouth.

[0027] Preferably, two fixing bands 3 are provided. The two ends of each fixing band 3 are respectively a fixed end and a connecting end. Each fixing band 3 is fixedly connected to the mask body 1 through the fixed end. The connecting end of one fixing band 3 is provided with a velcro surface, and the connecting end of the other fixing band 3 is provided with a hook surface. The connection of the two fixing bands 3 can be realized through the adhesion of the velcro surface and the hook surface. Generally, the velcro surface is provided with a long strip along the extending direction of the corresponding fixing band 3. By adhering the hook surface to different positions of the velcro surface, the overall length of the two fixing bands 3 can be adjusted, so as to adjust the tightness state according to the specific use situation. Preferably, the fixing band 3 is made of an elastic band, so that it is easier to wind and fix around the patient's head.

[0028] An oxygen tube socket is provided on the mask body 1. A breathing tube 4 can be inserted into the oxygen tube socket. Through the breathing tube 4, continuous positive pressure air flow is sent into the respiratory tract, so as to constantly apply a certain degree of positive pressure to the respiratory tract during the whole breathing cycle to realize pressurized oxygen supply treatment. The oxygen tube socket can directly install and insert the breathing tube 4. One end of the breathing tube 4 is communicated with an oxygen cylinder. A connection port is provided at the connection of the breathing tube 4 and the oxygen cylinder. The diameter of the connection port is larger than the diameter of the breathing tube 4 and is matched with the interface of the oxygen cylinder, so that the breathing tube 4 can be directly connected to the oxygen cylinder without setting up a simple breathing bag or a corrugated tube to connect the oxygen source.

[0029] It should be noted that the breathing tube 4 can be set as a Y-shaped structure. Specifically, the breathing tube 4 is provided with an output end and two input ends. The output end is communicated with the oxygen tube socket. One input end is a thin port communicated with the oxygen cylinder, and the other input end is a thick port that can be connected to an anesthetic machine corrugated tube or a simple breathing bag. There is a slightly thicker pipe between the two input ends. Through the setting of the two input ends, the connection of the oxygen cylinder or the anesthetic machine corrugated tube or the simple breathing bag can be set up. At the same time, corresponding to the two input ends, structures such as plugs or control valves are provided to realize the independent control of a single input end, and the input device can be selected based on the actual situation.

[0030] A regulating section is provided at a position of the breathing tube 4 close to the output end. The regulating section is set as a threaded tubular structure, and the length of the regulating section can be adjusted based on the actual situation, so as to avoid the inconvenient equipment setting situation where the short-circuit breathing bag abuts against the operating table.

[0031] The utility model facilitates the insertion of the gastroscope intubation by setting the oral pressure tube 2. At the same time, the sealed connection between the oral pressure tube 2 and the mask body 1 can ensure a high airtightness inside the mask body 1, facilitating the pressurized oxygen supply to patients under anesthesia, and not affecting the gastroscope operation of the endoscopist. A sealing part is arranged inside the oral pressure tube 2 to prevent air leakage from the oral pressure tube 2, thus ensuring the effect of pressurized oxygen supply.

[0032] Embodiment 2

[0033] As Figure 2 shown Figure 2 is a structural sectional view of the oral pressure tube; specifically, the sealing part includes a sealing ring 5 and a sealing film 6. The sealing ring 5 is set as a circular ring made of elastic material. The sealing ring 5 can be sleeved outside the gastroscope intubation, and under the action of its own elastic force, it is closely attached to the outer wall of the gastroscope intubation to ensure the sealing effect of the connection between the sealing ring 5 and the gastroscope intubation. The sealing film 6 is set as a circular ring. The inner ring edge of the sealing film 6 is sealed and connected to the sealing ring 5, and the outer ring edge of the sealing film 6 is sealed and connected to the inner wall of the oral pressure tube 2, so as to fix the sealing ring 5 inside the oral pressure tube 2 and realize the sealing of the gap between the gastroscope intubation and the oral pressure tube 2 through the sealing film 6.

[0034] During use, a gastroscope examination lubricant such as lidocaine is applied on the sealing ring 5. Through the relative sliding between the sealing ring 5 and the gastroscope intubation, it can ensure that the sealing part does not affect the insertion or pulling out operation of the endoscopist on the gastroscope intubation.

[0035] A first one-way valve 12 is arranged on the mask body 1. The first one-way valve 12 realizes the one-way outflow of gas from the inside of the mask body 1 to the outside. Thus, by controlling the discharge flow rate of the first one-way valve 12 and the oxygen supply flow rate of the breathing tube 4, a positive pressure state can be achieved on the inner surface of the mask body 1 to realize pressurized oxygen supply.

[0036] A second one-way valve 8 is arranged on the oral pressure tube 2. The second one-way valve 8 is arranged on the side of the sealing film 6 close to the mask body 1. The second one-way valve 8 realizes the one-way outflow of gas from the inside of the oral pressure tube 2 to the outside. By controlling the discharge flow rate of the second one-way valve 8, it is ensured that the patient can perform normal breathing operations.

[0037] As Figure 3 shown Figure 3 is a structural view of the sealing cover; the sealing part further includes a sealing cover 7. The sealing cover 7 is used to seal the end of the oral pressure tube 2, and when not in use for gastroscope detection, it seals the end of the oral pressure tube 2 to prevent a large amount of oxygen from being discharged from the oral pressure tube 2.

[0038] The sealing cover 7 is connected to the oral pressure tube 2 through a connecting band to prevent the loss of the sealing cover 7. A clamping ring 9 is provided at the end of the oral pressure tube 2 corresponding to the sealing cover 7. The clamping ring 9 extends annularly on the inner wall of the oral pressure tube 2 to form a closed circular ring. A fixing plate 10 is provided on the sealing cover 7. The fixing plate 10 is arranged as an arc plate, and the center of the fixing plate 10 is arranged on the axis of the oral pressure tube 2. A number of clamping blocks 11 are provided on the outer circumferential surface of the fixing plate 10. The cross-section of the clamping ring 9 is arranged as a semi-circular shape, and the clamping blocks 11 are arranged as hemispherical shapes. By squeezing the clamping blocks 11 into the oral pressure tube 2, the clamping blocks 11 contact the clamping ring 9 to cause the arc plate to deform to a certain extent until the clamping blocks 11 move into the clamping ring 9 in the oral pressure tube 2 to form a clamping and fixing structure, thereby realizing the fixation of the sealing cover 7 at the end of the oral pressure tube 2.

[0039] The clamping ring 9 and the clamping blocks 11 with an arc contact surface structure facilitate the disassembly and assembly of the clamping structure. The fixing plate 10 can be arranged as an integral circular ring structure or multiple fixing plates 10 can be provided, and the multiple fixing plates 10 are evenly distributed annularly around the center of the sealing cover 7, thereby realizing the clamping and fixation of the clamping ring 9 and the clamping blocks 11.

[0040] The diameter of the sealing cover 7 is larger than the outer diameter of the oral pressure tube 2, so as to completely seal and cover the end of the oral pressure tube 2 and ensure the sealing effect.

[0041] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
