Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a tablet dispenser. Background Art

[0002] The daily oral medications for inpatients in the hospital are dispensed by pharmacy staff according to doctors' prescriptions. The staff need to unpack the medications, select the correct dosage, dispense equal doses, and then have the nurses deliver them to the wards for distribution to the patients.

[0003] Currently, medications are dispensed from ordinary medicine bottles, often by opening the cap and pouring out the pills. This makes it difficult to control the number of pills dispensed, potentially resulting in a large amount being poured out at once. Then, the required number of pills are removed, and the remaining pills are poured back into the bottle. This process introduces contamination because the pills have already been handled by the patient, potentially contaminating other pills in the bottle. Furthermore, elderly patients with weaker memories may have difficulty remembering their dosage, affecting their treatment. Additionally, since each medication is contained in a single bottle, multiple medications need to be retrieved from or prepared in combination, wasting considerable time. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figure 1-6 This embodiment of a tablet dispenser includes a shell 1, a control panel mounted on the front of the shell 1, and an inner shell 3 fixed to the inner side of the shell 1 at the shell opening. The inner shell 3 is convex in shape, and six pill boxes 4 are snapped into place on the inner side of the inner shell 3. Each pill box 4 has a storage channel inside, and a groove 5 communicating with the storage channel is formed on the inner bottom wall. A stopper is inserted into the top of each pill box 4 inside the dispensing channel. The groove 5 passes through the pill box 4 and is divided into two sections: a receiving section and a pushing section. The receiving section is capsule-shaped, and the pushing section is convex in shape. The outer side of the inner shell 3... The inner shell 3 has a number of medicine outlets 22 that match the number of medicine boxes 4. The medicine outlets 22 are opposite to the receiving area. A push rod 6 is slidably connected in the chute 5 between the receiving area and the pushing area. The head of the push rod 6 is C-shaped and the tail is convex and matches the pushing area. The push rod is made of iron. A feeding component is installed at the center of the inner shell 3. A cover 9 is also fixed inside the inner shell 3 to cover the feeding component. An opening opposite to the pushing area is opened on the outer side of the cover 9. An installation plate 19 is fixed on the outer side of the inner shell 3 above the medicine outlet 22. A sensor 23 is installed on the installation plate 19.

[0023] In the above structure, the filled medicine box is first inserted into the inner shell and snapped in place, so that the chute is aligned with the medicine outlet and opening. The six medicine boxes are numbered and distinguished by the control panel and sensor. Then, the sensor receives and converts the signal, causing the feeding component to rotate to be aligned with the corresponding medicine box. The feeding component then pushes the medicine box, and the pushing end passes through the opening and extends into the chute to push the push rod. The head of the push rod pushes the tablet, ejecting the tablet from the medicine outlet. Then, it retracts and repeats the above operation to push out different medicines and complete the medicine distribution.

[0024] The outer shell 1 has an inner cylinder 2 fixed in the middle, which covers the bottom of the inner shell 3. The bottom of the inner cylinder 2 has a discharge port. The inner bottom wall of the outer shell 1 is slidably connected to a receiving box 17 located below the discharge port. When the medication delivery component pushes the tablet out of the dispensing port, the tablet falls into the inner cylinder and is guided by the inner cylinder to fall through the discharge port and be collected in the receiving box. After collection, the receiving box is removed, thus allowing the entire dose to be dispensed at once and avoiding contamination of the tablets.

[0025] Further optimization involves installing a lead screw device 18 on the inner bottom wall of the outer casing 1, with the nut end of the lead screw device 18 fixedly connected to the bottom of the medicine receiving box 17. Therefore, after the medicine receiving box has been used once, the lead screw device will automatically activate, pushing the medicine receiving box out to facilitate the patient in taking the medicine. After the medicine is taken out, the lead screw device will also drive the medicine receiving box to automatically retract.

[0026] The feeding assembly includes a rotating part installed at the bottom of the inner shell 3, and a pushing part is installed on the rotating end of the rotating part. The rotating part can drive the pushing part to rotate, thereby aligning the top end of the pushing part with the corresponding medicine box according to the sensor signal, thus realizing the dispensing of the required amount of medicine for one use.

[0027] Further optimization includes a rotating part comprising a stepper motor 10 mounted on the bottom of the inner shell 3 and a rotating gear 12 rotatably connected to the bottom of the inner shell 3. The rotating end of the stepper motor 10 is fixed with a drive gear 11 that meshes with the rotating gear 12. The rotating shaft of the rotating gear 12 extends into the interior of the inner shell 3, and a rotating plate 13 is fixed to the end of the rotating shaft. The pushing part is mounted on the rotating plate 13. Through the cooperation of a sensor and the stepper motor, the sensor sends a signal, and the stepper motor receives the signal. Therefore, the stepper motor drives the rotating gear to rotate via the drive gear, and the rotating plate also rotates along with the rotating gear until the pushing part is aligned with the corresponding medicine box.

[0028] In a further optimization, the pushing unit includes a servo motor 14 mounted on a rotating plate 13 and a slidably connected rack 16. The rotating end of the servo motor 14 is fixed with a main gear 15 that meshes with the rack 16, and the rack 16 is fixed with a magnet that can attract the tail end of the push rod 6. When the rotating plate rotates and drives the rack to face the corresponding medicine box, the servo motor runs, and through the engagement of the gear and the rack, it drives the rack to slide forward on the rotating plate until it passes through the opening and extends into the slide groove, attracting the tail end of the push rod and pushing the push rod to push the tablet that has fallen into the slide groove forward. During the pushing process, the push rod will also block the medicine storage channel until the tablet is pushed out through the medicine outlet, completing the tablet pushing work. At the same time, when the rack retracts, it will also drive the push rod to retract. After the push rod retracts, the new tablet will fall back into the slide groove through the medicine storage channel until it is in the pushing range, limiting the tail end of the push rod, thereby allowing the push rod to return to its original position. At the same time, the rack will also separate from the push rod.

[0029] In addition, two rubber rods 20 are fixed to the bottom of the mounting plate 19, and a baffle plate 21 is fixed between the bottoms of the two rubber rods 20 to block the dispensing port 22. In the initial state, the baffle plate blocks the dispensing port, thereby preventing the tablets inside the dispenser from being moved out through the slide groove during shaking. Because the rubber rods are flexible, a certain force is required to push the baffle plate up to move the tablet out, thus playing a limiting role and preventing the dispensing from being affected by shaking.

[0030] like Figure 5 Two guide rods 7 are fixed inside the pushing section of the slide groove 4, which pass through the tail end of the push rod 6. A spring 8 is sleeved on the outside of the guide rod 7 between the head and tail of the push rod 6. When the push rod is pushed out, the tail end of the push rod slides on the guide rod, and at the same time, it will compress the spring. Therefore, after the push is completed, the spring force can also push the push rod back to its original position. In addition, during the distribution and shaking process, the push rod can be prevented from shaking during sliding. Therefore, the push end of the rack can be fixed as a push block.

[0031] The working principle of the above embodiment is:

[0032] The pillbox is fixed by inserting it into the inner shell, and the medicine zone is set via a control panel and sensor on the outer shell. When a dose needs to be taken out, the sensor receives and sends a signal. At this time, the stepper motor drives the rotating gear through the drive gear to rotate, and the rotating plate follows suit until the rack aligns with the designated pillbox. Then, the servo motor drives the main gear to rotate, and the main gear drives the rack to push out. The rack extends through the opening into the slide groove and pushes the push rod. The push rod is guided forward by the guide rod and compresses the spring until the push rod pushes the pill out. At the same time, the medicine... The tablet pushes the medicine baffle, causing the rubber plate to bend until it reaches a certain range and falls into the inner cylinder. Then it falls into the receiving box. At this time, the pushing part retracts, and the spring drives the push rod to retract to the designated position. The tablet falls into the slide groove, and the rubber rod also drives the medicine baffle to block the medicine outlet again. The rotating part drives the pushing part to move to the next set of medicine boxes and repeat the above operation. The receiving box is moved out through the screw device. Therefore, it is convenient for patients to take out a single dose of medicine, which can also save a lot of time in dispensing medicine and prevent the tablet from being contaminated.
