This is to select the route of administration based on the patient's needs and the purpose of treatment, and directly help the patient solve the symptoms of the disease. If the method of administration is inappropriate, it will not only affect the absorption of the drug but also reduce the efficacy of the drug. Oral administration is a method of administration in which the drug is directly applied to the oral cavity instead of entering the digestive tract. After being absorbed through the rich capillaries of the oral mucosa, these drugs can fully play a role in the body, and this type of drug takes effect faster and will not be affected by digestive tract function.

[0013] The operation method of the device:

[0014] Step 1: Apply the medicine. The patient first adds the medicine into the medicine dosage bottle, seals the medicine with the piston, and then tightly inserts one end of the medicine dosage bottle into one end of the dosage bottle holder. The patient then inserts the dosage bottle holder with one end of the medicine dosage bottle into the device, and at the same time, the elastic pinching rods at both ends of the dosage bottle holder slide inside the first limiting groove. When the top end of the elastic pinching rod contacts the inner wall of the top end of the first limiting groove, the bottom end of the inclined limiting block contacts the inner wall of the bottom end of the first limiting groove. At this time, the medicine dosage bottle at the top of the dosage bottle holder is located at the bottom end of the micro-mist needle seat, and at the same time, the bottom end of the needle inside the micro-mist needle seat is located inside the medicine dosage bottle.

[0015] Step 2: medication, the patient puts the top of the driving nozzle shell into the mouth, presses the button, the button drives the inclined buckle rod to move, when the top of the inclined buckle rod no longer fixes the pusher, the pusher, the dosage bottle holder and the medicine dosage bottle move upward quickly under the action of the second spring's own rebound force, at this time the needle pierces the piston, so that the medicine inside the medicine dosage bottle is transported upward through the needle, the pressure of the medicine delivery can be increased by the pressurized atomizer head, and finally the atomized medicine is sprayed into the patient's mouth through the atomizer nozzle;

[0016] Step three: counting, after the pusher and the dial ring are fitted together, the dial ring can be moved up, and the counting drive wheel is rotated by the dial piece, and at the same time, the dial ring compresses the third spring, and the second elastic return block can prevent the counting drive wheel from rotating, and the counting drive wheel drives the connecting drive inclined rod to rotate synchronously. When the counting drive wheel rotates one circle, that is, after the counting drive wheel rotates ten times, the driven counting wheel is rotated once by connecting the driving inclined rod and the inclined groove, and the driven counting wheel can be limited by the first elastic return block, so that the driven counting wheel can only rotate in the same direction, and the rotation direction of the driven counting wheel and the counting drive wheel is the same;

[0017] Step 4: Observation. Since the transparent counting outer cylinder is transparent, the patient can observe the counting marks on the surface of the driven counting wheel and the counting driving wheel through the visual window. The counting marks can help the patient to grasp the number of medications in real time.

[0018] Step 5: Reset. The button and the inclined buckle rod can be reset by the first spring. The patient pulls the bottom end of the dosage bottle holder, and the dosage bottle holder drives the pusher to reset through the inclined limit block in the middle of the elastic pinch rod. When a click sound is heard, the pusher is reset. At the same time, the top of the pusher no longer resists the dial ring. The dial ring is reset under the action of the third spring's own rebound force, and the paddle is reset under the action of its own rebound force to facilitate the next counting work;

[0019] Step 6: Change the medicine. The patient pinches the elastic pinch rods on both sides of the dosage bottle holder so that the inclined limit block is no longer inside the first limit groove. At this time, the patient can take out the dosage bottle holder, the elastic pinch rod and the medicine dosage bottle. The patient only needs to replace another medicine dosage bottle with assembled medicine, and then the next medication can be carried out.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] When the patient uses the device, the patient first adds the medicine into the medicine dosage bottle, seals the medicine by the piston, and then tightly inserts one end of the medicine dosage bottle into one end of the dosage bottle holder, so that the medicine dosage bottle and the dosage bottle holder are fastened. The patient then inserts the dosage bottle holder with one end of the medicine dosage bottle into the device, and at the same time makes the elastic pinching rods at both ends of the dosage bottle holder slide inside the first limiting groove. When the inclined surface of the top end of the inclined limiting block conflicts with the inclined surface of the bottom end of the pusher, the elastic pinching rod can be moved closer to the dosage bottle holder, thereby facilitating the inclined limiting block to enter the first limiting groove. When the top end of the elastic pinching rod conflicts with the inner wall of the top end of the first limiting groove, the inclined limiting block is reset under the action of the elastic pinching rod's own resilience. At this time, the bottom end of the inclined limiting block The pusher is then moved upwards to release the needle from the bottom of the nozzle, and the needle is then moved upwards to release the needle from the bottom of the nozzle. The pressurized atomizer head can increase the pressure of drug delivery, and finally the atomized drug is sprayed into the patient's oral cavity through the atomizer nozzle. At the same time, the propeller and the dial ring can be fitted to make the dial ring move up. At this time, the dial ring slides inside the transparent counting outer cylinder. The upwardly moved dial ring can deform the dial piece, and the counting drive wheel is rotated through the dial piece. At the same time, the dial ring compresses the third spring, and the lower end of the counting drive wheel collides with the inclined surface of one end of the second elastic resistance return member, which can cause the second elastic resistance return member to deform. When the counting drive wheel rotates once, the second elastic resistance return member is reset, thereby fixing the counting drive wheel again, thereby preventing the counting drive wheel from rotating, so that the counting drive wheel can only rotate in one direction. The rotating counting drive wheel drives the connecting drive inclined rod to rotate synchronously. When the counting drive wheel rotates once, the second elastic resistance return member is reset, thereby fixing the counting drive wheel again, thereby preventing the counting drive wheel from rotating, so that the counting drive wheel can only rotate in one direction. The rotating counting drive wheel drives the connecting drive inclined rod to rotate synchronously. When the counting driving wheel rotates one circle, that is, after the counting driving wheel rotates ten times, the inclined surface at the bottom end of the connected driving inclined rod conflicts with the inclined surface at one end of the inclined surface block, thereby causing the connected driving inclined rod to deform and move one end upward. At this time, the inclined surface at the top end of the connected driving inclined rod fits with the inclined surface on one side of the inclined surface groove, and one side of the connected driving inclined rod fits with the other side of the inclined surface groove. The driven counting wheel is rotated once by connecting the driving inclined rod and the inclined surface groove. When one end of the connected driving inclined rod is separated from the inclined surface block, the connected driving inclined rod is reset, and the top end of the connected driving inclined rod is no longer fitted with the inclined surface groove, thereby causing the driven counting wheel to stop rotating. When the driven counting wheel rotates, the inner wall of the driven counting wheel conflicts with the first elastic resistance member, thereby causing the first elastic resistance member to deform.After the driven counting wheel rotates once, it is reset under the action of the rebound force of the first elastic resistance member, so that the driven counting wheel is limited again, so that the driven counting wheel can only rotate in the same direction. The driven counting wheel and the counting drive wheel have the same rotation direction. Through the inclined groove, the connecting driving inclined rod and the inclined block, the driven counting wheel can rotate once when the counting drive wheel rotates one circle, and the rotation direction of the driven counting wheel can also be the same as that of the counting drive wheel. The rotation direction of the counting drive wheel can be limited by the inner fixed ring and the second elastic resistance member. The rotation direction of the driven counting wheel can be limited by the transparent counting inner seat and the first elastic resistance member. Since the transparent counting outer cylinder is transparent, the patient can observe the counting marks on the surfaces of the driven counting wheel and the counting drive wheel through the visual window. The counting marks can facilitate the patient to grasp the number of medications in real time. After the medication is completed, the patient releases the button, and the button and the inclined buckle rod can be reset by the first spring. The patient pulls the bottom end of the dosage bottle holder, and the dosage bottle holder drives the pusher to reset through the inclined limit block in the middle of the elastic pinch rod. At this time, the pusher The spring is compressed. When the bottom end of the pusher contacts the inclined surface of the top end of the inclined surface buckle rod, the inclined surface can make the inclined surface buckle rod drive the button to move to the side away from the cover plate and compress the first spring until a click sound is heard. At this time, the pusher is reset. At the same time, the top end of the pusher no longer contacts the dial ring. The dial ring is reset under the action of the rebound force of the third spring. After the dial ring is reset, the paddle is reset under the action of its own rebound force to facilitate the next counting work. The patient pinches the elastic pinch rods on both sides of the dosage bottle holder, and the elastic pinch rods are deformed, so that the inclined The surface limit block is no longer inside the first limit groove. At this time, the patient can take out the dosage bottle holder, the elastic pinch rod and the medicine dosage bottle. The patient only needs to replace another medicine dosage bottle with assembled medicines. At this time, the next medication can be given. This device is not only convenient for patients to count, but also can perform a single replacement of medicines. By only replacing the medicines, the patient's use cost can be greatly reduced. By replacing a stable medicine dose, the patient's quality effect can be guaranteed. At the same time, this device is simple and convenient to use, providing great convenience for patients.

The inner wall of the counting drive wheel 24 is fixedly connected with a connecting driving bevel rod 30, and the top of one end of the connecting driving bevel rod 30 is a bevel shape that matches one side of the bevel groove 29. One side of the top of the inner fixed ring 25 is fixedly connected with a bevel block 31, and one end of the bevel block 31 is a bevel shape. The bottom of one end of the connecting driving bevel rod 30 is a bevel shape that matches one end of the bevel block 31. One end of the inner fixed ring 25 is fixedly connected with a second elastic resistance return member 32, and the connection between the second elastic resistance return member 32 and the inner fixed ring 25 is symmetrically distributed with the bevel block 31. The middle part of the second elastic resistance return member 32 is arc-shaped, and the middle part of the second elastic resistance return member 32 is rotatably connected to the inside of the transparent counting outer cylinder 27. One end of the elastic resistance member 32 is an inclined surface, and the inclined surface meshes with the bottom end of the counting driving wheel 24. The inner wall of the transparent counting inner seat 21 is symmetrically provided with a second limiting groove 33. The interior of the second limiting groove 33 is slidably connected to the limiting plate 34, and one end of the limiting plate 34 is respectively fixedly connected to the inner fixed ring 25. The top of the dial ring 22 is symmetrically fixedly connected with a paddle 35. After the pusher 9 is fitted with the dial ring 22, the dial ring 22 can be moved upward. At this time, the dial ring 22 slides inside the transparent counting outer cylinder 27. The upwardly moved dial ring 22 can deform the paddle 35, and the counting driving wheel 24 is rotated through the paddle 35. At the same time, the dial ring 22 compresses the third spring 26. After the lower end of the counting driving wheel 24 conflicts with the inclined surface at one end of the second elastic resistance member 32,The second elastic resistance member 32 can be deformed. When the counting drive wheel 24 rotates once, the second elastic resistance member 32 is reset, thereby fixing the counting drive wheel 24 again, thereby preventing the counting drive wheel 24 from rotating, so that the counting drive wheel 24 can only rotate in one direction. The rotating counting drive wheel 24 drives the connecting driving inclined rod 30 to rotate synchronously. When the counting drive wheel 24 rotates one circle, that is, the counting drive wheel 24 rotates ten times, the inclined surface at the bottom end of the connecting driving inclined rod 30 conflicts with the inclined surface at one end of the inclined surface block 31, so that the connecting driving inclined rod 30 is deformed, so that one end of it moves upward, at this time, the inclined surface of the top end of the connecting driving inclined rod 30 is fitted with the inclined surface of one side of the inclined surface groove 29, and one side of the connecting driving inclined rod 30 is fitted with the other side of the inclined surface groove 29, and the driven counting wheel 23 is rotated once by connecting the driving inclined rod 30 and the inclined surface groove 29. When one end of the connecting driving inclined rod 30 is separated from the inclined surface block 31, the connecting driving inclined rod 30 is reset, and the top end of the connecting driving inclined rod 30 is no longer fitted with the inclined surface groove 29, so that the driven counting wheel 23 stops rotating. When the driven counting wheel 23 rotates, the driven counting wheel The inner wall of 23 resists the first elastic resistance member 28, so that the first elastic resistance member 28 is deformed. When the driven counting wheel 23 rotates once, it is reset under the action of the first elastic resistance member 28's own resilience, so that the driven counting wheel 23 is limited again, so that the driven counting wheel 23 can only rotate in the same direction. The driven counting wheel 23 and the counting driving wheel 24 have the same rotation direction. Through the inclined groove 29, the connecting driving inclined rod 30 and the inclined block 31, the counting driving wheel 24 can rotate one circle and the driven counting wheel 23 can rotate once. The rotation direction of the driven counting wheel 23 can also be made the same as that of the counting driving wheel 24. The rotation direction of the counting driving wheel 24 can be limited by the inner fixing ring 25 and the second elastic resistance member 32. The rotation direction of the driven counting wheel 23 can be limited by the transparent counting inner seat 21 and the first elastic resistance member 28. Since the transparent counting outer cylinder 27 is transparent, the patient can observe the counting marks on the surfaces of the driven counting wheel 23 and the counting driving wheel 24 through the visual window 4. The counting marks can facilitate the patient to grasp the number of drug administrations in real time and facilitate the patient to count;

[0041] It should be noted that the bottom end of the driving nozzle housing 1 is adapted to the top end of the base 2, and the bottom end of the base 2 is adapted to one side of the cover plate 3, which is convenient for the assembly of the device. The diameter of the bottom end of the micro-mist needle seat 18 is adapted to the inner diameter of the drug dosage bottle 15, which is convenient for squeezing out the drug during medication. The top end of the inclined buckle rod 7 is all inclined, which is convenient for subsequent continued medication. One end of the button 6 is C-shaped, and the stability of locking the thruster 9 is improved through a symmetrical fixed structure. The top end of the inclined limit block 14 is all inclined, and the bottom end of the thruster 9 is an inclined shape adapted to the top end of the inclined limit block 14, which is convenient for automatic locking. The angle between the elastic pinch rod 13 and the dosage bottle holder 11 is fifteen degrees, which is convenient for the inclined limit block 14 to enter the interior of the first limit groove 12. The blocks 14 are all slidably connected to the first limiting grooves 12, the bottom ends of the elastic pinching rods 13 are all wavy, the bottom ends of the dosage bottle holders 11 are anti-slip rings, which are convenient for patients to pinch the elastic pinching rods 13 and the dosage bottle holders 11, the paddles 35 are all spirally upward, and the top ends of the paddles 35 are all in conflict with the bottom ends of the counting driving wheels 24, so that the dial ring 22 can push the counting driving wheel 24 to rotate through the paddles 35, and the surfaces of the driven counting wheel 23 and the counting driving wheel 24 are both provided with counting marks, which are convenient for counting, and the transparent counting inner seat 21 and the transparent counting outer cylinder 27 are both made of transparent materials, and the driven counting wheel 23 and the counting driving wheel 24 are both rotated between the transparent counting inner seat 21 and the transparent counting outer cylinder 27, so as to improve the rotation stability of the driven counting wheel 23 and the counting driving wheel 24;

[0042] The device operates as follows:

[0043] Step 1: Apply the medicine. The patient first adds the medicine into the medicine dosage bottle 15, seals the medicine through the piston 16, and then tightly inserts one end of the medicine dosage bottle 15 into one end of the dosage bottle holder 11. The patient then inserts the dosage bottle holder 11 with one end of the medicine dosage bottle 15 into the device, and at the same time, the elastic pinching rods 13 at both ends of the dosage bottle holder 11 slide inside the first limiting groove 12. When the top of the elastic pinching rod 13 conflicts with the inner wall of the top of the first limiting groove 12, the bottom end of the inclined limiting block 14 conflicts with the inner wall of the bottom end of the first limiting groove 12. At this time, the medicine dosage bottle 15 at the top of the dosage bottle holder 11 is located at the bottom end of the micro-mist needle seat 18, and at the same time, the bottom end of the needle 19 inside the micro-mist needle seat 18 is located inside the medicine dosage bottle 15.

[0044] Step 2: medication, the patient puts the top of the driving nozzle housing 1 into the mouth, presses the button 6, and the button 6 drives the inclined buckle rod 7 to move. When the top of the inclined buckle rod 7 no longer fixes the pusher 9, the pusher 9, the dosage bottle holder 11 and the medicine dosage bottle 15 move upward rapidly under the action of the second spring 10's own rebound force. At this time, the needle 19 pierces the piston 16, so that the medicine inside the medicine dosage bottle 15 is transported upward through the needle 19, and the pressure of the medicine delivery can be increased by the pressurized atomizer head 20, and finally the atomized medicine is sprayed into the patient's mouth through the atomizer nozzle 5;

[0045] Step three: counting, after the pusher 9 is fitted with the dial ring 22, the dial ring 22 can be moved up, and the counting drive wheel 24 is rotated by the paddle 35. At the same time, the dial ring 22 compresses the third spring 26, and the second elastic return block 32 can prevent the counting drive wheel 24 from rotating. The counting drive wheel 24 drives the connecting drive inclined rod 30 to rotate synchronously. When the counting drive wheel 24 rotates one circle, that is, after the counting drive wheel 24 rotates ten times, the driven counting wheel 23 is rotated once by connecting the driving inclined rod 30 and the inclined groove 29. The driven counting wheel 23 can be limited by the first elastic return block 28, so that the driven counting wheel 23 can only rotate in the same direction, and the rotation direction of the driven counting wheel 23 and the counting drive wheel 24 is the same;

[0046] Step 4: Observation. Since the transparent counting outer cylinder 27 is transparent, the patient can observe the counting marks on the surfaces of the driven counting wheel 23 and the counting driving wheel 24 through the visual window 4. The counting marks can help the patient to grasp the number of medications in real time.

[0047] Step 5: Reset. The button 6 and the inclined buckle rod 7 can be reset by the first spring 8. The patient pulls the bottom end of the dosage bottle holder 11. The dosage bottle holder 11 drives the pusher 9 to reset through the inclined limit block 14 in the middle of the elastic pinch rod 13. When a click sound is heard, the pusher 9 is reset. At the same time, the top of the pusher 9 no longer resists the dial ring 22. The dial ring 22 is reset under the action of the self-rebound force of the third spring 26. The paddle 35 is reset under the action of its own rebound force to facilitate the next counting work.

[0048] Step 6: Change the medicine. The patient pinches the elastic pinch rods 13 on both sides of the dosage bottle holder 11 so that the inclined limit block 14 is no longer in the first limit groove 12. At this time, the patient can take out the dosage bottle holder 11, the elastic pinch rod 13 and the medicine dosage bottle 15. The patient only needs to replace another medicine dosage bottle 15 with assembled medicine, and then the next medication can be carried out.

[0049] Working principle: When the patient uses the device, the patient first adds the medicine into the inside of the medicine dosage bottle 15, seals the medicine through the piston 16, and then tightly inserts one end of the medicine dosage bottle 15 into one end of the dosage bottle holder 11, so that the medicine dosage bottle 15 and the dosage bottle holder 11 are fastened, and the patient then inserts the dosage bottle holder 11 with one end of the medicine dosage bottle 15 into the device, and at the same time, the elastic pinching rods 13 at both ends of the dosage bottle holder 11 slide inside the first limiting groove 12. When the inclined surface of the top end of the inclined surface limiting block 14 conflicts with the inclined surface of the bottom end of the pusher 9, the elastic pinching rod 13 can be moved closer to the dosage bottle holder 11, thereby facilitating the inclined surface limiting block 14 to enter the inside of the first limiting groove 12. When the top end of the elastic pinching rod 13 and the top end of the first limiting groove 12 are in contact with each other, the elastic pinching rod 13 can be moved closer to the dosage bottle holder 11, thereby facilitating the inclined surface limiting block 14 to enter the inside of the first limiting groove 12. When the inner wall of the first end of the elastic pinching rod 13 conflicts with the inner wall of the second end of the first limiting groove 12, the inclined limiting block 14 is reset under the action of the elastic pinching rod 13's own resilience. At this time, the bottom end of the inclined limiting block 14 conflicts with the inner wall of the bottom end of the first limiting groove 12, thereby fixing the dosage bottle holder 11 inside the pusher 9. At this time, the medicine dosage bottle 15 at the top of the dosage bottle holder 11 is located at the bottom end of the micro-mist needle seat 18, and at the same time, the bottom end of the needle 19 inside the micro-mist needle seat 18 is located inside the medicine dosage bottle 15. After the patient puts the top end of the driving nozzle shell 1 into his mouth, he presses the button 6, and the button 6 slides inside the base 2. The button 6 compresses the first spring 8 and drives the inclined buckle rod 7 to move at the same time. When the top end of the inclined buckle rod 7 no longer fixes and limits the pusher 9, the second spring 10 is used to make the pusher 9 move. The pusher 9 moves upward quickly, and the pusher 9 that moves upward quickly drives the dosage bottle holder 11 and the medicine dosage bottle 15 to move upward quickly. Since the needle 19 is fixed, the needle 19 can pierce the piston 16 through the medicine dosage bottle 15 and the piston 16 that move upward quickly, and the piston 16 is limited by the micro-mist needle seat 18, so that the medicine inside the medicine dosage bottle 15 can be transported upward through the needle 19, and the pressure of the medicine delivery can be increased through the pressurized atomizer head 20, and finally the atomized medicine is sprayed into the patient's oral cavity through the atomizer nozzle 5. At the same time, the pusher 9 can fit with the dial ring 22 to make the dial ring 22 move upward. At this time, the dial ring 22 slides inside the transparent counting outer cylinder 27, and the upwardly moved dial ring 22 can deform the paddle 35, so that the counting The driving wheel 24 rotates, and the dial ring 22 compresses the third spring 26. After the lower end of the counting driving wheel 24 contacts the inclined surface of one end of the second elastic resistance member 32, the second elastic resistance member 32 can be deformed. After the counting driving wheel 24 rotates once, the second elastic resistance member 32 is reset, thereby fixing the counting driving wheel 24 again, thereby preventing the counting driving wheel 24 from rotating, so that the counting driving wheel 24 can only rotate in one direction. The rotating counting driving wheel 24 drives the connecting driving inclined rod 30 to rotate synchronously. When the counting driving wheel 24 rotates one circle, that is, after the counting driving wheel 24 rotates ten times, the inclined surface at the bottom end of the connecting driving inclined rod 30 contacts the inclined surface at one end of the inclined surface block 31, thereby causing the connecting driving inclined rod 30 to deform.One end of the driven counting wheel 23 is moved upward, and at this time, the inclined surface of the top end of the connected driving inclined rod 30 is fitted with the inclined surface of one side of the inclined surface groove 29, and one side of the connected driving inclined rod 30 is fitted with the other side of the inclined surface groove 29. The driven counting wheel 23 is rotated once by connecting the driven inclined rod 30 and the inclined surface groove 29. When one end of the connected driving inclined rod 30 is separated from the inclined surface block 31, the connected driving inclined rod 30 is reset, and the top end of the connected driving inclined rod 30 is no longer fitted with the inclined surface groove 29, so that the driven counting wheel 23 stops rotating. When the driven counting wheel 23 rotates, the inner wall of the driven counting wheel 23 resists the first elastic resistance return member 28, so that the first elastic resistance return member 28 is deformed. After the driven counting wheel 23 rotates once, at this time, the first elastic resistance return member 2 8 resets under the action of its own resilience, thereby limiting the driven counting wheel 23 again, so that the driven counting wheel 23 can only rotate in the same direction, and the driven counting wheel 23 and the counting driving wheel 24 have the same rotation direction. Through the inclined groove 29, the connecting driving inclined rod 30 and the inclined block 31, the counting driving wheel 24 can rotate once when the driven counting wheel 23 rotates one circle, and at the same time, the rotation direction of the driven counting wheel 23 can be the same as that of the counting driving wheel 24. The rotation direction of the counting driving wheel 24 can be limited by the inner fixed ring 25 and the second elastic return resistance 32, and the rotation direction of the driven counting wheel 23 can be limited by the transparent counting inner seat 21 and the first elastic return resistance 28. Since the transparent counting outer cylinder 27 is transparent , so that the patient can observe the counting marks on the surfaces of the driven counting wheel 23 and the counting driving wheel 24 through the visual window 4, and the counting marks can facilitate the patient to grasp the number of drug administrations in real time. After the drug administration is completed, the patient releases the button 6, and the button 6 and the inclined buckle rod 7 can be reset through the first spring 8. The patient pulls the bottom end of the dosage bottle holder 11, and the dosage bottle holder 11 drives the pusher 9 to reset through the inclined limit block 14 in the middle of the elastic pinch rod 13. At this time, the second spring 10 is compressed by the pusher 9. When the bottom end of the pusher 9 conflicts with the inclined surface at the top of the inclined buckle rod 7, the inclined surface can make the inclined buckle rod 7 drive the button 6 to move to the side away from the cover plate 3, and compress the first spring 8 until a click sound is heard. At this time, the pusher 9 is pushed. The pusher 9 is reset, and the top of the pusher 9 no longer resists the dial ring 22. The dial ring 22 is reset under the action of the self-rebound force of the third spring 26. After the dial ring 22 is reset, the paddle 35 is reset under the action of its own rebound force to facilitate the next counting work. The patient pinches the elastic pinching rods 13 on both sides of the dosage bottle holder 11, and the elastic pinching rods 13 are deformed so that the inclined surface limit block 14 is no longer in the first limit groove 12. At this time, the patient can take out the dosage bottle holder 11, the elastic pinching rod 13 and the medicine dosage bottle 15. The patient only needs to replace another medicine dosage bottle 15 with assembled medicines. At this time, the next medication work can be carried out. The device is not only convenient for the patient to perform counting work, but also can perform a single replacement of the medicine.By only replacing the medicine, the patient's cost of use can be greatly reduced. By replacing the stable drug dosage, the quality effect of the patient can be guaranteed. At the same time, the device is simple and convenient to use, providing great convenience for patients.
