The working process and principle are as follows: before use, the fixing mechanism 2 is required to be plugged into the oral cavity of a patient, based on the fact that the left end and the right end of the circular ring 201 are fixedly connected with the corrugated pipe 202, the interior of the corrugated pipe 202 is communicated with the Y-shaped pipe 204 and the interior of the latex ball 205, firstly, the transverse size of the fixing mechanism 2 is adjusted, the latex ball 205 is pressed oppositely, so that the air in the latex ball 205 is conducted and squeezed into the corrugated pipe 202 through the Y-shaped pipe 204, the air pressure in the corrugated pipe 202 is increased, the corrugated pipe 202 extends, because one end of the corrugated pipe 202, far away from the circular ring 201, is fixedly connected with the abutting block 203, the other end of the abutting block 203 is fixedly connected to the middle of the elastic sheet 206, along with the extension of the corrugated pipe 202, the abutting block 203 abuts against the elastic sheet 206 towards one side, far away from the circular ring 201, so that the elastic sheet 206 gradually contracts and folds, and simultaneously accumulates force, because the upper end and the lower end of the elastic sheet 206 are respectively hinged with the upper supporting block 207 and the lower end, along with the contraction of the elastic sheet 206, the upper supporting block 207 and the lower supporting block 210 are close to each other, so that the longitudinal size of the fixing mechanism 2 is gradually reduced, a hinge rod 208 is hinged to the middle parts of the upper supporting block 207 and the lower supporting block 210, a rubber block 209 is hinged to the other end of the hinge rod 208, along with the reduction of the distance between the upper supporting block 207 and the lower supporting block 210, the rubber blocks 209 are gradually contracted and back-away by matching the transmission of the hinge rod 208, so that the transverse size of the fixing mechanism 2 is increased, after the fixing mechanism 2 is plugged in, the latex ball 205 is released from being pressed, so that the air in the corrugated pipe 202 returns to the interior of the latex ball 205, at the moment, the corrugated pipe 202 is contracted and drives the resisting blocks 203 to be close to each other, the elastic sheet 206 is not pressed and gradually expanded, so that the distance between the upper supporting block 207 and the lower supporting block 210 is gradually increased, and the left and right rubber blocks 209 are self-expanded and back-away by matching the transmission of the hinge rod 208, so that the transverse size and the longitudinal size of the equipment plug are synchronously changed, the effect of being convenient for to plug in and fix based on human mouth structure is reached, uncomfortable sense before reducing equipment and plugging in.
After the fixing of the fixing device is completed, because the top left side of the fixing block 31 is rotatably connected with the limiting disc 34, the axis transmission of the limiting disc 34 is connected with the micro motor, the starting motor rotates the limiting disc 34, the end part limit based on the limiting disc 34 is connected with the groove block 35, the bottom of the groove block 35 is fixedly connected with the plug body 36, along with the rotation limit of the limiting disc 34, the groove block 35 drives the plug body 36 to move up and down on the left branch of the air cavity 33, when the groove block 35 moves down, the air pressure in the air cavity 33 rises, because the upper side and the lower side of the fixing block 31 are limited and hinged with the baffle 37, one end of the baffle 37 far away from the guide pipe 32 is fixedly connected with the magnetic block 38, at this time, the lower baffle 37 of the fixing block 31 is opened to discharge air, when the groove block 35 moves up, the air pressure in the air cavity 33 is reduced, the upper baffle 37 of the fixing block 31 is opened, the lower baffle 37 is closed, saliva is sucked through the guide pipe 32 inserted in the slot 211, the groove block 35 moves circularly, so that saliva near the lower branch block 210 at the bottom of the oral cavity of the patient is continuously sucked through the upper guide pipe 32 and pushed out through the lower guide pipe 32, the used guide pipe 32 is pulled out after detection is finished and discarded, the effect of sucking saliva by negative pressure to avoid cleaning is achieved, and the cleaning cost of the device is reduced.
In summary, the patient oral fixation device used during a digestive endoscopy procedure is passed through the ring 201. Left and right sides both ends fixedly connected with bellows 202, during fixed patient's oral cavity, through control extrusion latex ball 205, make bellows 202 extend the shrink, and then the change supports and keeps away from between the piece 203, flexure strip 206 is supported and is kept away from dorsad, make upper bracket piece 207 and lower piece 210 be close to each other, cooperation hinge rod 208 transmission makes keeping away from dorsad between the rubber block 209 simultaneously, increase the horizontal size of equipment and reduce vertical size simultaneously, it supports upper and lower jaw to finish extrusion latex ball 205 to go up piece 207 and lower piece 210 after stuffing, thereby reach and be convenient for to stuff in and fixed effect based on human mouth structure, reduce the uncomfortable sense before equipment is stuffed in.
And, this patient's oral cavity fixing device who uses in digestive endoscopy process, the air cavity 33 has been seted up through the inside of fixed block 31, after the oral cavity is fixed, start spacing dish 34 axle center motor, spacing dish 34 rotates spacing groove block 35, make groove block 35 reciprocate, when groove block 35 moves down, the inside atmospheric pressure of air cavity 33 rises, fixed block 31 downside baffle 37 is opened, exhaust gas, when groove block 35 moves up, the inside atmospheric pressure of air cavity 33 reduces, fixed block 31 upside baffle 37 is opened, downside baffle 37 is closed, inhale saliva via pegging graft at slot 211 inside pipe 32, pipe 32 that extracts the use after detecting the completion abandons, thereby reach the effect that negative pressure suction saliva avoided cleanness, reduce the clean cost of equipment.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
