Description

Technical Field

[0001] This utility model relates to the field of drug dispensing technology, specifically to a sterile drug dispenser. Background Technology

[0002] Medical institutions such as nursing homes, rehabilitation centers, and community hospitals often need to prepare medicines for patients. Since each person's treatment course is different, medical staff usually open large bottles of medicine, count them, divide them into small packages, and finally distribute them to different people. However, this process can easily cause contamination of the pills, which requires a medicine dispenser.

[0003] Existing technology typically uses the slots of a sorting disc to determine the number of tablets. The tablets enter the slots of the sorting disc through the feed chute, and then the sorting disc is rotated to allow the tablets in the slots to enter the small package. However, this method can only determine the approximate number of tablets and cannot achieve precise counting. The tablets still need to be counted by medical staff to determine the number of tablets, which increases the burden on medical staff and reduces the efficiency of dispensing. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-6 As shown, a sterile drug dispenser includes a base plate 1, and further includes: A pill-retrieving assembly 15, positioned above the base plate 1, is used to retrieve pills. The assembly includes a fixing plate 151 with a through hole 152. The fixing plate 151 and the through hole 152 facilitate the fixing of the stepper motor 16 and the passage of its output shaft 161 through the through hole 152. A second baffle 155 is fixedly connected to one side of the fixing plate 151, and a slide rail 156 is fixedly connected to one end of the baffle 155. The baffle 155 and the slide rail 156 help to block the pills in the pill-retrieving slot 171, preventing them from slipping out. When the pill-retrieving slot 171 moves above the slide rail 156, the pills fall onto the slide rail 156. A medicine placement trough 153 is fixedly connected to one side of the bottom of the fixed plate 151. A baffle 154 is fixedly connected to one side of the medicine placement trough 153. By setting the medicine placement trough 153 and the baffle 154, it is beneficial to provide space for the placement of the tablets and prevent the tablets from sliding off one side of the dispensing trough 171. A stepper motor 16 is fixedly connected to one side of the fixed plate 151. An output shaft 161 is fixedly connected to the output end of the stepper motor 16. Setting the stepper motor 16 and the output shaft 161 is beneficial to provide a power source for the rotation of the dispensing tray 17. The dispensing tray 17 is fixedly connected to the outside of the output shaft 161. The dispensing tray 17 has six dispensing troughs 171 inside. It should be noted that the stepper motor 16 receives command signals and drives the motor through a closed-loop control system. The encoder feeds back the actual value and adjusts the error to achieve precise control. The speed of the stepper motor 16 is set to the low speed position. The medicine dispensing tray 171 is an inclined columnar structure. When the medicine dispensing tray 171 is no longer blocked by the first baffle 154 and the second baffle 155, the medicine tablets in the medicine dispensing tray 171 will slide off from one side.

[0016] A weighing assembly 18 is installed below the dispensing assembly 15 to determine the number of tablets. The weighing assembly 18 includes two fixing rods 181. A limiting box 182 is fixedly connected between the two fixing rods 181. The fixing rods 181 and the limiting box 182 provide space for the tablets to temporarily stop. A balance plate 184 is installed below the limiting box 182. The bottom of the limiting box 182 contacts the top side of the balance plate 184. Fixing rods 183 are rotatably connected to both sides of the balance plate 184. The fixing rods 183 help to set a balance point on the balance plate 184. A fixing box 185 is fixedly connected to the top side of the balance plate 184, and a counterweight 186 is fixedly connected to the other side of the top of the balance plate 184. The fixing box 185 and the counterweight 186 help to maintain balance on the balance plate 184. The counterweight 186 can counteract the weight of the fixing box 185 at the other end.

[0017] It should be noted that the second fixing rod 183 is rotatably connected to the center point of the balance plate 184. The balance plate 184, the fixing box 185 and the counterweight 186 are all made of lightweight materials to improve the sensitivity to the weight of the tablets so that tilting can occur and allow the tablets to enter the feeding hopper 7.

[0018] The top of the base plate 1 is fixedly connected to a support column 2, and the top of the support column 2 is fixedly connected to a dispensing chamber 3. By setting the support column 2, it is beneficial to provide stable support for the dispensing chamber 3.

[0019] A second support column 5 is fixedly connected to one side of the top of the dispensing compartment 3. A fixed frame 14 is fixedly connected to the top of one side of the second support column 5. One end of the fixed frame 14 is fixedly connected to one side of the fixed plate 151. By setting the second support column 5 and the fixed frame 14, it is beneficial to provide support for the fixed plate 151 and prevent the stepper motor 16 from vibrating.

[0020] The top of the dispensing compartment 3 is fixedly connected to the inlet pipe 6, and the top of the inlet pipe 6 is fixedly connected to the inlet hopper 7. The top of the inlet hopper 7 is fixedly connected to the bottom of the first fixing rod 181 and the second fixing rod 183. By setting the inlet hopper 7 and the inlet pipe 6, it is beneficial to collect the falling tablets and prevent the tablets from falling outside the dispensing compartment 3.

[0021] The dispensing compartment 3 is internally connected to a dispensing tray 10, which has six dispensing slots 11. The dispensing tray 10 and dispensing slots 11 facilitate the dispensing of tablets and allow time for medical staff to handle the tablet boxes. A handle 13 is fixedly connected to one side of the dispensing tray 10, which facilitates the rotation of the dispensing tray 10 so that the dispensing slot 11 with the tablets is directly opposite the dispensing port 4. Dustproof plates 12 are fixedly connected to both sides of the dispensing compartment 3 to prevent contamination of the tablets by the external environment.

[0022] It should be noted that the dustproof panel 12 is made of transparent plastic to allow medical staff to observe the inside of the dispensing compartment 3.

[0023] The bottom of the dispensing compartment 3 is provided with a dispensing port 4. A dispensing hopper 9 is fixedly connected inside the dispensing port 4. A dispensing pipe 8 is fixedly connected to the bottom of the dispensing hopper 9. By setting the dispensing hopper 9 and the dispensing pipe 8, it is convenient to transfer the tablets inside the dispensing tank 11 into the independent small dispensing box.

[0024] Working principle: The fixed rod 183 is rotatably connected to the center point of the balance plate 184. The balance plate 184, the fixed box 185, and the counterweight 186 form a stable balance. Under the action of the limiting box 182, the balance plate 184 can only tilt to one side. X-1 tablets are placed in the fixed box 185. At this time, one end of the balance plate 184 in the fixed box 185 is heavier, but due to the presence of the limiting box 182, the other end of the balance plate 184 cannot tilt. Then, the medicine taking component 15 takes out the tablets one by one and puts them into the limiting box 182. When the number of tablets in the limiting box 182 reaches X-1, the two ends of the balance plate 184 are balanced again. When another tablet is taken out... After entering the limiting box 182, the balance of the balance plate 184 is broken and it tilts to one side of the limiting box 182. The tablets inside the limiting box 182 slide off the balance plate 184 and enter the dispensing chamber 3 to complete the counting. Then, due to the tablets inside the fixing box 185, the other end of the balance plate 184 contacts the bottom of the limiting box 182 again. The number of tablets entering the dispensing chamber 3 is X tablets. Then, turn the handle 13 to align the dispensing slot 11 with the dispensing port 4. The tablets are caught at the dispensing tube 8 with a small package and the dispensing is completed. Medical staff can adjust the type and quantity of medicines inside the fixing box 185 to determine the amount of medicine dispensed each time.
