The use method and the advantages of the invention are as follows: this kind of portable intelligent stomach tube drainage device is when using, and the working process is as follows:

as shown in FIG. 3, when the drainage tube 8 is installed, one end of the drainage tube 8 is inserted into the tapered barrel 24, so that the end of the drainage tube 8 is in an expanded state, and the end is tightly attached to the outer surface of the tapered barrel 24, thereby helping to maintain the sealing property and improving the drainage effect, and the spiral steel wire 28 is inserted into the drainage tube 8, it should be noted that the spiral steel wire 28 cannot extend out of the drainage tube 8 to avoid damage to the stomach, then the threaded sleeve 25 is connected to the sleeve 23 through the screw thread, and the conical surface structure on the inner wall of the threaded sleeve 25 is tightly attached to the outer surface of the drainage tube 8, which is sleeved on the tapered barrel 24, thereby not only further maintaining the sealing property between the remaining tapered barrels 24 of the drainage tube 8, but also improving the connection strength between the drainage tube 8 and the tapered barrel 24 and avoiding separation, and then as shown in FIG. 2, the other end of the drainage tube 8 sequentially passes through one guide wheel 6, two guide wheels, The guide sleeve 41 on the two side walls of the disinfection box 19 is sequentially penetrated between the second guide wheel 7 and the third guide wheel 9 from left to right.

As described above, after the installation of the drainage tube 8 is completed, when the intubation operation is performed, one end of the drainage tube 8, which is far away from the sleeve 23, is pulled out, so that the drainage tube 8 applies a downward pressure to the guide wheel three 9, as shown in fig. 1 and 2, so that the guide wheel three 9 drives the piston plate 13 to move downward in the pump barrel 12 through the slide rod one 10, and simultaneously the spring one 11 is stretched, so that the disinfectant in the lower cavity inside the pump barrel 12 is pressurized in the process that the spring one 11 obtains a restoring force to move downward the piston plate 13, because the conducting direction of the check valve one 15 corresponding to the lower cavity points to the corresponding cavity inside the pump barrel 12, and the conducting direction of the check valve two 16 points to the corresponding volute 20, the disinfectant in the lower cavity enters the disinfection box 19 through the water pipe two 17 and the water pipe three 18, the drainage tube 8 is disinfected, and the disinfectant drives the impeller 27 in the corresponding volute 20 to rotate when passing through the water pipe two 17, thereby make impeller 27 drive worm 38 through bevel gear group 35 and rotate, and then make worm 38 drive turbine 39 and rotate, make turbine 39 drive brush hair 40 simultaneously and rotate, and scrub drainage tube 8 through brush hair 40, thereby realize when carrying out the intubate operation, the in-process of pulling out drainage tube 8 is disinfected drainage tube 8 simultaneously, time saving and labor saving, and easy operation, antiseptic solution after the disinfection is collected in waste liquid case 22 through water pipe four 21, so that recovery processing, as shown in fig. 1 and 5, when drainage tube 8 pulls out the maximum length, catching groove 37 on the piston plate 13 corresponds with catching rod 42 this moment, make the wedge end of catching rod 42 peg graft in catching groove 37 under the effect of spring three 36, carry out spacing to piston plate 13, thereby accomplish pulling out and disinfecting processing to drainage tube 8.

As mentioned above, the piston plate 13 pressurizes the lower cavity, and at the same time, the upper cavity generates a suction force, since the first check valve 15 corresponding to the upper cavity is turned on to point to the corresponding cavity in the pump barrel 12, and the second check valve 16 is turned on to point to the corresponding volute 20, the suction force pumps the disinfectant from the disinfectant tank 3 to the upper cavity through the first water pipe 14 so as to disinfect and flush the drainage tube 8 during tube drawing.

After intubation, the drainage device is started to drain the stomach of a patient, the stomach liquid is pumped out by the drainage device through the drainage tube 8, the sleeve 23 and the drainage tube 4, in the drainage process, when particles in the stomach enter the drainage tube 8 and block the drainage tube 8, at the moment, the internal pressure of the drainage tube 8 is reduced, so that the sliding plate 30 moves downwards, the sliding rod two 32 drives the pressing rod 33 to move downwards, the spring two 31 is stretched, so that the spring two 31 obtains restoring force, when the pressing rod 33 is in abutting contact with the key switch 34, the key switch 34 is communicated, the micro motor 5 works, the micro motor 5 drives the spiral steel wire 28 to rotate, and the blockage in the drainage tube 8 is dredged, so that the drainage tube 8 is automatically ensured to be unblocked in real time, the blockage occurs in the drainage process, the dredging is automatically performed, the intellectualization is improved, and the intubation again is not needed, labour saving and time saving reduces the painful of disease, improves treatment moreover, and after the mediation of drainage tube 8, drainage tube 8 internal pressure resets to make slide 30 move up through two 32 drive depression bars 33 of slide bar under the effect of the restoring force of two 31 springs, and keep away from contactless with key switch 34, thereby make key switch 34 outage, and then make micro motor 5 stop work, energy saving consumed the festival.

After the tube is pulled out, the buckling rod 42 is pulled outwards, so that the buckling rod 42 is separated from the buckling groove 37, the limit of the piston plate 13 is removed, the piston plate 13 synchronously drives the guide wheel II 7 and the guide wheel III 9 to move upwards through the slide rod I10 under the action of the restoring force of the spring I11, the drainage tube 8 is automatically stored without carrying and managing the drainage tube 8 independently, the carrying is convenient, the disinfectant in the upper cavity in the pump cylinder 12 is pressurized when the piston plate 13 moves upwards, the disinfectant is conveyed into the water tube III 18 through the corresponding water tube II 17, the drainage tube 8 is automatically cleaned and disinfected, the attachments on the outer side wall of the drainage tube 8 are washed away and disinfected, the disinfectant drives the impeller 27 in the corresponding volute 20 to rotate in the process of flowing in the water tube II 17, the impeller 27 drives the worm 38 to rotate through the bevel gear set 35, and the worm 38 drives the worm wheel 39 to rotate, so that the turbine 39 synchronously drives the bristles 40 to rotate and brushes the drainage tube 8 through the bristles 40, thereby improving the disinfection effect.

As mentioned above, the piston plate 13 pressurizes the upper cavity, and at the same time, the lower cavity generates a suction force, since the first check valve 15 corresponding to the lower cavity is turned on and directed to the corresponding cavity in the pump barrel 12, and the second check valve 16 is turned on and directed to the corresponding volute 20, the suction force pumps the disinfectant from the disinfectant tank 3 to the lower cavity through the first water pipe 14 so as to disinfect and flush the drainage tube 8 during intubation.

Whole device is when using, is convenient for carry drainage tube 8 to can realize accomodating drainage tube 8 automatically, can carry out cleaning and disinfecting to drainage tube 8 at the in-process that receive and releases drainage tube 8 simultaneously automatic drive disinfection mechanism in addition, at the drainage in-process, when meetting drainage tube 8 and blockking up, can automatic start dredge the mechanism and carry out automatic mediation to drainage tube 8, improve the intellectuality and the automation of whole device, help improving the treatment to the disease.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
