Description

Technical Field

[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 mouth is an important part of our body. It is the starting part of the digestive tract. Since we need to eat and drink water through the mouth in our lives, many bacteria and harmful substances will also breed in the mouth. If it is not cleaned 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, 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 dipped with a sponge and put into the mouth. However, since this method cannot guarantee the uniform coating of the medicine, oral administration is generally carried out through a drug delivery device, which can help patients deliver the medicine to the affected area accurately, quickly and safely, thereby improving the absorption efficiency and treatment effect of the medicine.

[0003] In the prior art, during oral treatment, different patients and different diseases require different medications for treatment, which requires the use of multiple medication devices during the treatment process, which is relatively cumbersome. If a single medication device is used to administer multiple medications, the medication used to treat the previous patient will remain in the device pipeline and will be pumped out when the next patient is treated, resulting in unnecessary medication being given to the patient. This will not only cause medication waste, but may also lead to patient dissatisfaction after the patient learns of the problem. Summary of the Invention

The next time the medicine is pumped out, the normal saline in the medicine outlet tube will be pumped out first. The affected area will be flushed and moistened by the pumping of the normal saline before the liquid medicine is pumped out, thus ensuring a better effect of the medicine.

[0026] 6. By setting the limiting mechanism, when one cartridge is pressed, the other cartridges will be reset, which improves the degree of automation of the device. At the same time, by setting the limiting mechanism, only the cross pin of one cartridge can be inserted into the cross slot, thus ensuring that only one drug can be pumped out at a time, avoiding mixing of pumped drugs;

[0027] 7. By observing the depth of the first pump block, you can quickly judge the amount of liquid medicine in the cartridge, making the amount of liquid medicine more obvious and ensuring timely replacement;

[0028] 8. The medicine pump is driven by a micro motor, which rotates a fixed number of circles to ensure the accuracy of the medicine pumped, making the amount of medicine pumped out more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] Reference Figure 1-9 An oral medication device for oral treatment includes 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;

[0040] Each two guide rods 4 are slidably connected to a group of medicine storage mechanisms;

[0041] The main body 1 is provided with a medicine pumping mechanism, which consists of a driving assembly and a pumping assembly. Both the driving assembly and the pumping assembly are 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 to a second screw 17 through a bearing. The chassis 13 is communicated with the mounting groove 2. The pumping assembly includes a fixed column 20, which is fixedly connected to multiple fixed tubes 22 and a medicine outlet tube 23 through the fixed column 20.

[0042] The side wall of the main body 1 is provided with a flushing mechanism;

[0043] The side wall of the mounting seat 3 is provided with a limiting mechanism.

[0044] The drive 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 drive rod 15. The end of the drive 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 set 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 shafts 10 through bearings. The shaft 10 is fixedly connected to the first gear 12. The first gear 12 is meshed sequentially, and the first gear 12 is meshed in a cyclic sequence (such as Figure 5 As shown, one of the first gears 12 is meshed with the second gear 18, and the rotating shaft 10 is provided with a cross slot 11. The micromotor 14 rotates in integer circles. The micromotor 14 drives the turntable 16 to rotate through the drive 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, it drives the second gear 18 to rotate one circle. Due to the provision of the one-way bearing, the second gear 18 does not drive the second screw 17 to rotate at this time. The second gear 18 drives the first gear 12 meshed with it to rotate. Through the meshing of the first gears 12, all the first gears 12 rotate. The rotation of the first gear 12 drives the rotating shaft 10 to rotate, and the liquid medicine in the corresponding drug storage mechanism is pumped out. After the drug pumping stops, the accumulated elastic force of the torsion spring 19 is released, causing the second gear 18 to rotate one circle, thereby driving the first gear 12 to reverse, recovering the excess liquid medicine in the pipeline, avoiding the waste of liquid medicine caused by the residual liquid medicine in the pipeline, and also avoiding the pumping of unnecessary medicine into the patient.

[0045] 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 drug outlet pipe 23 is fixedly connected to the main body 1. One end of the drug outlet pipe 23 extends through the through cavity 21, and the other end extends through the outside of the main body 1. An atomizing nozzle (not shown in the figure) is also provided at one end of the drug outlet pipe 23 located outside the main body 1 to ensure the atomized spraying of the medicine and improve the effect of the medicine.

[0046] The medicine storage mechanism includes a medicine cartridge 5 with a concave cross-section and 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. The side wall of the medicine cartridge 5 is rotatably connected to a first screw 6 through a bearing. The thread rotation directions of the first screws 6 of two adjacent medicine cartridges 5 are opposite. 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. The rest of the structure is smooth. The thread lead angle of the first screw 6 is less 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, and a sealing rubber ring is provided at the threaded connection to ensure the sealing of the threaded connection. One end of the first screw 6 located outside the medicine cartridge 5 is fixedly connected to a cross pin 8, which can be inserted into the cross slot 11 (such as Figure 4 As shown), the side wall of the cartridge 5 is fixedly connected to a side block 31, and the side wall of the cartridge 5 is fixedly connected to a pump outlet tube 9, which is sealed 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.

[0047] 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. A second pump block 25 is sealed and slidably connected to 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 smooth. The thread lead angle of the second screw 17 is greater than the equivalent friction angle of the spiral pair composed of 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 fixedly connected with a saline tube 26 running through them. The saline tube 26 connects the medicine outlet tube 23 with the saline cylinder 24. The side wall of the saline cylinder 24 is fixedly connected with an injection tube 27. 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 back into the medicine cartridge 5, so that the medicine can smoothly return to the medicine cartridge 5, and at the same time prepares for pumping out the physiological saline when the next medication is given. A certain amount of physiological saline is first given for flushing before pumping the medicine to ensure the cleanliness and moistness of the affected area, which can greatly improve the effect of the medicine.

[0048] The limiting mechanism includes a plurality of sliding sleeves 28 (such as Figure 8As 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 the piston column 30 through the sliding groove 29. The cross section of the piston column 30 is T-shaped (as shown Figure 4 As 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 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 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, 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 last used cartridge 5 slides out of the corresponding cross groove 11, thereby automatically separating, greatly improving the degree of 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 are not driven to rotate at the same time, thereby avoiding the situation of pumping out two medicines at the same time; Figure 8 As shown, only one piston rod 30 is fully 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 fully extended from the sliding sleeve 28.

[0049] The outer wall of the cartridge 5 is painted with pigment and glued with a label. The cartridge 5 is painted 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 the color.

[0050] 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.

[0051] The guide rod 4 is fixedly connected to a positioning block 34 (such as Figure 6 As shown), the positioning block 34 is set so that the cartridge 5 cannot be pressed further after it is pressed to a certain position, to avoid excessive pressing that affects the normal pumping of the drug. A plurality of anti-slip pads 36 are glued to the side wall of the main body 1. The setting of the anti-slip pads 36 ensures the stability of the device during use and avoids slipping.

[0052] 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.

[0053] 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.

[0054] In the present invention, when it is necessary to use the device to administer medicine, first determine the medicine to be used, press the corresponding cartridge 5, and 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.

[0055] 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 is rotated 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 is charged, and the second gear 18 is not driven 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. The mutual engagement causes all the first gears 12 to rotate. The rotation of the first gear 12 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the first screw 6 to rotate through the cooperation between the cross slot 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 pipe 23 through the pump outlet pipe 9 and the fixed pipe 22, thereby pumping out the physiological saline in the cavity 21 and the medicine outlet pipe 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 pipe 23.

[0056] After the medicine pumping is completed, the button switch 35 is released, and the micromotor 14 stops rotating. At this time, the elastic force accumulated in the torsion spring 19 is released, causing the second gear 18 to reverse one circle, thereby driving the first gear 12 to reverse, causing the first screw 6 to reverse, 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 retracted 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. 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. The physiological saline pushes the medicine outlet pipe 23 and the medicine liquid in the cavity 21 back into the medicine cartridge 5, and prepares for pumping out physiological saline for the next medication.

[0057] 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 pressing the corresponding cartridge 5, continue to operate according to the above steps.

[0058] 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 mounting slot 2 and replaced with a new drug cartridge 5 containing the drug.

[0059] The amount of saline can be determined by observing the depth of the second pump block 25 . When the amount of saline is insufficient, the saline can be replenished by sucking it in through a syringe and inserting it into the injection tube 27 .
