[0001] The present invention relates to the technical field of oral treatment, and in particular to an oral medication device for oral treatment. Background Art

[0002] The oral cavity is an important part of our body. It is the starting part of the digestive tract. Since we need to eat and drink through the mouth in our lives, many bacteria and harmful substances will breed in the mouth. If we do not clean it in time or due to our own reasons, different diseases will occur in our mouth. For the treatment of oral diseases, common treatment methods include applying medicine to the affected area and curing oral diseases. In the early days, the medicine was applied to the wound with a cotton swab or a sponge was used to dip the medicine into the mouth. However, this method cannot guarantee uniform coating of the medicine. Therefore, oral drug administration is generally carried out through a drug delivery device, which can help patients accurately, quickly and safely deliver the medicine to the affected area, thereby improving the absorption efficiency and therapeutic effect of the medicine.

[0003] In the prior art, during oral treatment, different patients and different diseases require different medicines for treatment, which requires the use of multiple drug delivery devices during the treatment process, which is rather cumbersome.

DETAILED DESCRIPTION

[0018] Reference Figure 1-9 , an oral drug delivery device for oral treatment, comprising a main body 1, the main body 1 is provided with a mounting groove 2, a mounting seat 3 is fixedly connected in the mounting groove 2, and a plurality of guide rods 4 are fixedly connected to the side wall of the mounting seat 3; Every two guide rods 4 are slidably connected together with a group of medicine storage mechanisms; The main body 1 is provided with a medicine pump mechanism, which is composed of a driving assembly and a pumping assembly. The driving assembly and the pumping assembly are both provided at the main body 1. The driving assembly includes a hollow chassis 13, which is fixedly connected to the side wall of the main body 1. The side wall of the chassis 13 is rotatably connected with a second screw 17 through a bearing. The chassis 13 is connected with the mounting groove 2. The pumping assembly includes a fixed column 20, and the fixed column 20 is fixedly connected with a plurality of fixed tubes 22 and a medicine outlet tube 23. The side wall of the main body 1 is provided with a flushing mechanism; The side wall of the mounting seat 3 is provided with a limiting mechanism.

[0019] The driving assembly also includes a micro motor 14, which is a servo motor and can accurately control the number of revolutions. The micro motor 14 is fixedly connected to the inner bottom wall of the chassis 13 through a bracket. The output shaft of the micro motor 14 is fixedly connected to a driving rod 15, and the end of the driving rod 15 away from the micro motor 14 is fixedly connected to a turntable 16. The end of the second screw 17 located in the chassis 13 is rotatably connected to a second gear 18 through a one-way bearing. A torsion spring 19 is fixedly connected between the second gear 18 and the turntable 16. The one-way bearing is arranged so that when pumping medicine, the second gear 18 does not drive the second screw 17 to rotate. After stopping, when the second gear 18 reverses under the action of the torsion spring 19, it will drive the second screw 17 to rotate. The mounting seat 3 is rotatably connected to multiple rotating shafts 10 through bearings. The rotating shaft 10 is fixedly connected to the first gear 12. The first gears 12 are meshed sequentially, and the first gears 12 are meshed in a cyclic sequence (such as Figure 5 As shown in the figure, one of the first gears 12 is meshed with the second gear 18, the rotating shaft 10 is provided with a cross slot 11, the micro motor 14 rotates in integer circles, and the micro motor 14 drives the turntable 16 to rotate through the driving rod 15. When the turntable 16 rotates the first circle, the torsion spring 19 stores force and does not drive the second gear 18 to rotate. When the turntable 16 rotates the second circle, the second gear 18 is driven to rotate one circle. Due to the setting of the one-way bearing, the second gear 18 does not drive the second screw 17 to rotate at this time, and the second gear 18 drives the first gear 12 meshed therewith to rotate. Through the meshing of the first gears 12, all the first gears 12 are rotated, and the rotation of the first gear 12 drives the rotating shaft 10 to rotate, which will pump out the medicine of the corresponding medicine storage mechanism. After stopping the pumping of medicine, the elastic force accumulated in the torsion spring 19 is released, so that the second gear 18 is reversed by one circle, thereby driving the first gear 12 to reverse, and the excess medicine in the pipeline is recovered, so as to avoid the waste of medicine caused by the remaining medicine in the pipeline, and at the same time, it is also avoided to pump unnecessary medicine into the patient.

[0020] The pump-out assembly also includes a through cavity 21, which is opened in the fixed column 20, one end of the fixed tube 22 extends through the through cavity 21, and the other end extends through the mounting groove 2, the medicine outlet pipe 23 is fixedly connected with the main body 1, one end of the medicine outlet pipe 23 extends through the through cavity 21, and the other end extends through the outside of the main body 1, and an atomizing nozzle (not shown in the figure) is also provided at one end of the medicine outlet pipe 23 located outside the main body 1 to ensure the atomization spraying of the medicine and improve the effect of the medicine.

[0021] The medicine storage mechanism includes a medicine cartridge 5 with a concave cross-section with an opening facing one side. The medicine cartridge 5 is slidably connected to the corresponding guide rod 4. A first pump block 7 is sealed and slidably connected inside the medicine cartridge 5. A first screw 6 is rotatably connected to the side wall of the medicine cartridge 5 through a bearing. The threads of the first screws 6 of two adjacent medicine cartridges 5 have opposite rotation directions. A section of the first screw 6 located inside the medicine cartridge 5 is provided with a thread and is threadedly connected to the first pump block 7, and the remaining portion is a smooth structure. The thread lead angle of the first screw 6 is smaller than the equivalent friction angle of the spiral pair formed by the first pump block 7 and the first screw 6, so that only the rotation of the first screw 6 can make the first pump block 7 move, and the first pump block 7 cannot drive the first screw 6 to rotate. A sealing rubber ring is provided at the threaded connection to ensure the sealing of the threaded connection. A cross pin 8 is fixedly connected to one end of the first screw 6 located outside the medicine cartridge 5, and the cross pin 8 can be inserted into the cross groove 11 (such as Figure 4 As shown), the side wall of the cartridge 5 is fixedly connected to a side block 31, and a pump-out tube 9 is fixedly connected to the side wall of the cartridge 5. The pump-out tube 9 is sealingly and slidably sleeved with the corresponding fixed tube 22. The design of the detachable cartridge 5 makes the replacement of the cartridge 5 more convenient.

[0022] The flushing mechanism includes a saline cylinder 24 with a concave cross-section with an opening facing one side, the saline cylinder 24 is filled with physiological saline, the saline cylinder 24 is fixedly connected to the side wall of the main body 1, and a second pump block 25 is sealed and slidably connected inside the saline cylinder 24. The second screw 17 is rotatably connected to the side wall of the saline cylinder 24 through a bearing, a section of the second screw 17 located in the saline cylinder 24 is provided with a thread and is threadedly connected to the second pump block 25, and the rest of the structure is a smooth structure. The thread lead angle of the second screw 17 is greater than the equivalent friction angle of the spiral pair formed by the second screw 17 and the second pump block 25, so that the sliding of the second pump block 25 can also drive the second screw 17 to rotate, that is, it can be driven in both directions, and a sealing rubber ring is provided at the threaded connection to ensure the sealing of the threaded connection. The saline cylinder 24, the main body 1, and the medicine outlet tube 23 are connected with a saline tube 26 which penetrates and is fixedly connected. The saline tube 26 connects the medicine outlet tube 23 with the saline cylinder 24. The side wall of the saline cylinder 24 is connected with an injection tube 27 which penetrates and is fixedly connected. When the second gear 18 is reversed, under the action of the one-way bearing, the second gear 18 drives the second screw 17 to rotate. The rotation of the second screw 17 causes the second pump block 25 to slide through the threaded connection, and the physiological saline in the saline cylinder 24 is pumped into the medicine outlet tube 23 through the saline tube 26. The physiological saline pushes the medicine outlet tube 23 and the medicine liquid in the cavity 21 to flow back into the medicine cartridge 5, so that the medicine liquid can flow back into the medicine cartridge 5 smoothly. At the same time, it prepares for pumping out the physiological saline when administering the medicine next time. Before pumping the medicine, a certain amount of physiological saline is first given for flushing to ensure the cleanliness and moistness of the affected area, which can greatly improve the effect of the medicine.

[0023] The limiting mechanism includes a plurality of sliding sleeves 28 (such as Figure 8 As shown, the sliding sleeve 28 is fixedly connected to the side wall of the mounting seat 3, and the sliding sleeve 28 is provided with a sliding groove 29. The sliding sleeve 28 is sealed and slidably connected to a piston column 30 through the sliding groove 29. The cross section of the piston column 30 is T-shaped (as shown in FIG. Figure 4As shown in the figure, the piston rod 30 is limited by the sliding groove 29 so that it cannot slide out of the sliding sleeve 28. The sliding sleeve 28 is penetrated and fixedly connected with a fixing ring 32. The fixing ring 32 is a hollow structure. The fixing ring 32 and the sliding sleeve 28 are penetrated and fixedly connected with a connecting pipe 33. The connecting pipe 33 connects the fixing ring 32 with the corresponding sliding groove 29. The sliding sleeve 28, the connecting pipe 33 and the fixing ring 32 are all filled with hydraulic oil. When the cartridge 5 is pressed downward, the side block 31 of the side wall of the cartridge 5 moves accordingly, and drives the corresponding piston rod 30 to slide into the sliding groove 29, pumping the hydraulic oil in the sliding groove 29 into the fixing ring 32 through the connecting pipe 33. As the hydraulic oil is pumped out, the other piston rod 30 that slides in slides, thereby pushing the cartridge 5 used last time, and then the cross pin 8 of the pressed cartridge 5 is inserted into the corresponding cross groove 11, and the cross pin 8 of the cartridge 5 used last time slides out of the corresponding cross groove 11, thereby automatically separating, greatly improving the automation of the device, and if two or more cartridges 5 are pressed at the same time, the cross pins 8 of these cartridges 5 cannot be inserted into the corresponding cross groove 11, thereby ensuring that the cross pins 8 of two cartridges 5 will not be driven to rotate at the same time, thereby avoiding the situation where two drugs are pumped out at the same time; Figure 8 As shown, only one piston rod 30 is completely inserted into the sliding sleeve 28 (i.e., at the same time, only one cross pin 8 of the lower cartridge 5 is inserted into the corresponding cross groove 11), and the other piston rods 30 are in the extreme state of being completely extended out of the sliding sleeve 28.

[0024] The outer wall of the cartridge 5 is coated with pigment and glued with a label. The cartridge 5 is coated with paints of different colors, and the label is marked with drug information, so that the drug to be used can be quickly determined by color.

[0025] Both the brine tube 26 and the injection tube 27 are provided with a one-way valve. The one-way valve in the brine tube 26 only allows liquid to enter the brine tube 26 from the brine cylinder 24, and the one-way valve in the injection tube 27 only allows liquid to enter the brine cylinder 24 from the injection tube 27.

[0026] The guide rod 4 is fixedly connected with a positioning block 34 (such as Figure 6 As shown in the figure, the positioning block 34 is set so that the cartridge 5 cannot be pressed further after being pressed to a certain position, so as to avoid excessive pressing and affecting the normal drug pumping. A plurality of anti-skid pads 36 are glued to the side wall of the main body 1. The setting of the anti-skid pads 36 ensures the stability of the device during use and avoids slipping.

[0027] A button switch 35 is fixedly connected to the side wall of the main body 1. The button switch 35 is connected to the micro motor 14 through a PLC control circuit. The PLC control circuit controls the micro motor 14 to rotate in integer circles after the button switch 35 is pressed.

[0028] It should be noted that the bearings used in the present invention are all sealed bearings, so as to ensure the sealing of the bearing connection and avoid leakage at the bearing connection.

[0029] In the present invention, when it is necessary to use the device to administer medicine, first determine the medicine to be used, and press the corresponding cartridge 5. When the cartridge 5 is pressed downward, the side block 31 of the side wall of the cartridge 5 moves accordingly, and drives the corresponding piston column 30 to slide into the sliding groove 29, and the hydraulic oil in the sliding groove 29 is pumped into the fixed ring 32 through the connecting pipe 33. As the hydraulic oil is pumped out, the other piston column 30 that slides in slides, thereby pushing the cartridge 5 used last, and then the cross pin 8 of the pressed cartridge 5 is inserted into the corresponding cross groove 11, and the cross pin 8 of the cartridge 5 used last slides out of the corresponding cross groove 11.

[0030] After the corresponding cartridge 5 is pressed, the main body 1 is held, the medication location is found, the medication outlet tube 23 is aligned with the medication location, and the button switch 35 is pressed. After the button switch 35 is pressed, the micro motor 14 can rotate in integer circles. The micro motor 14 drives the turntable 16 to rotate through the driving rod 15. When the turntable 16 rotates the first circle, the torsion spring 19 accumulates force and does not drive the second gear 18 to rotate. When the turntable 16 rotates the second circle, the second gear 18 is driven to rotate one circle. Due to the setting of the one-way bearing, the second gear 18 does not drive the second screw 17 to rotate at this time, and the second gear 18 drives the first gear 12 meshing with it to rotate. Through the first gear 12 The mutual meshing causes all the first gears 12 to rotate, and the rotation of the first gears 12 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the first screw 6 to rotate through the cooperation of the cross groove 11 and the cross pin 8 (that is, only the liquid medicine in one cartridge 5 is pumped out). The first screw 6 drives the first pump block 7 to slide through the threaded connection to pump out the liquid medicine in the cartridge 5. The liquid medicine enters the cavity 21 and the medicine outlet tube 23 through the pump outlet tube 9 and the fixed tube 22, thereby pumping out the physiological saline in the cavity 21 and the medicine outlet tube 23 and spraying it on the affected area to rinse and moisten the affected area. When the turntable 16 rotates the third circle, a certain amount of liquid medicine will be pumped out through the medicine outlet tube 23.

[0031] After the medicine pumping is completed, the button switch 35 is released, and the micro motor 14 stops rotating. At this time, the elastic force accumulated in the torsion spring 19 is released, so that the second gear 18 is reversed for one circle, thereby driving the first gear 12 to reverse, and the first screw 6 is reversed, so that the first pump block 7 slides back a certain distance, and the medicine outlet pipe 23 and the medicine liquid in the cavity 21 are recovered into the medicine cartridge 5. At the same time, under the action of the one-way bearing, the second gear 18 drives the second screw 17 to rotate, and the rotation of the second screw 17 will cause the second pump block 25 to slide through the threaded connection, and the physiological saline in the saline cylinder 24 is pumped into the medicine outlet pipe 23 through the saline pipe 26, and the physiological saline is used to push the medicine outlet pipe 23 and the medicine liquid in the cavity 21 back into the medicine cartridge 5, and at the same time prepare for pumping out the physiological saline when the next medication is given.

[0032] After one drug pumping is completed, the exposed part of the drug outlet tube 23 is disinfected. When the next patient needs a different drug, the drug to be pumped out is determined and the corresponding cartridge 5 is pressed. At this time, the last used cartridge 5 will be reset. After the corresponding cartridge 5 is pressed, continue to operate according to the above steps.

[0033] The drug usage status can be judged by observing the depth of the first pump block 7. When the drug is used up, the corresponding drug cartridge 5 is pulled out of the installation slot 2 and replaced with a new drug cartridge 5 containing the drug.

[0034] The amount of saline solution can be determined by observing the depth of the second pump block 25 . When the amount of saline solution is insufficient, the saline solution can be supplemented by sucking it into a syringe and inserting it into the injection tube 27 .
