Technical Field

[0001] The invention belongs to the technical field of the production of potassium hydrogen phosphate injection, specifically the production process of potassium hydrogen phosphate injection. Background Art

[0002] Potassium hydrogen phosphate injection is an important medical drug, mainly used as a phosphorus supplement in total parenteral nutrition therapy, applicable to phosphorus supplementation for patients who need to fast for more than 5 days due to medium or above surgeries or other traumas. The general production process steps are: weighing → liquid preparation → stirring → volume fixing → filtration → filling and sealing → edge trimming → sterilization → lamp inspection → leak detection → packaging.

[0003] In the existing process of sterilizing potassium hydrogen phosphate injection, a steam sterilization device is used. High-temperature steam is generated by heating water to sterilize potassium hydrogen phosphate injection. During the process of heating water to generate high-temperature steam for sterilization, corresponding impurity scale will be produced, which will adhere to the inner wall. The injection support cylinder above can be taken out for direct cleaning, but the device inside the lower part of the cylinder needs to be cleaned with tools. Since the bottom is relatively deep and it is inconvenient to observe and clean clearly, the cleaning will be incomplete. Therefore, it needs to be improved. Summary of the Invention

S5. Discharging and trimming: The operator at the station confirms that the equipment is in good condition, notifies the blowing, filling and sealing operator to execute online operation, observes the trimming effect of the ampoules. If the effect is qualified, continue to sample and detect the wall thickness; if the trimming effect is unqualified, notify the blowing, filling and sealing operator to cancel the online operation until the trimming effect is adjusted to meet the requirements before carrying out normal discharging. S6. Sterilization: After receiving the sealed ampoules delivered by the discharging station operator, count the quantity, which should be consistent with the label, and transfer the sterilization tray containing the sealed ampoules to the steam sterilization device 1. S7. Leak detection: After verifying the name, specification, batch number, batch size, and production date of the ampoules to be leak-detected, transfer the products to be leak-detected to the packaging operation room. S8. Packaging: Label the sealed ampoules, print codes on the small boxes, pack them into boxes, and then into cases. Among them, the steam sterilization device 1 described in S6 further includes: a placement cylinder 5, which is movably installed inside the steam sterilization device 1; a first cleaning mechanism 6, which is arranged inside the cavity of the steam sterilization device 1 and is located below the placement cylinder 5; a driving mechanism 7, which is arranged inside the steam sterilization device 1 and is located on one side of the first cleaning mechanism 6. Among them, the driving mechanism 7 includes a driving motor 701 arranged inside the steam sterilization device 1 and located on one side of the first cleaning mechanism 6. The output end of the driving motor 701 is fixedly sleeved with a driving gear 702. One side of the first cleaning mechanism 6 is provided with a mounting block 703 located at the top of one side of the driving gear 702. One side of the top of the driving gear 702 is provided with a linkage shaft 704 located inside the inner wall of the mounting block 703.

[0021] By the operation of the driving motor 701, the driving gear 702 can be driven to rotate, so that the linkage shaft 704 moves left and right inside the mounting block 703, thereby driving the whole mounting block 703 and the first cleaning mechanism 6 to move up and down. When the whole first cleaning mechanism 6 moves downward, the scale at the bottom of the inner cavity of the steam sterilization device 1 can be cleaned in time.

[0022] As Figure 1 shown, a control panel 2 is arranged on one side of the steam sterilization device 1. A sealing cover 3 is movably installed on the top of the steam sterilization device 1. A locking mechanism 4 is arranged on the top of the steam sterilization device 1 on one side of the sealing cover 3.

[0023] Adopting the above solution; through the design of the sealing cover 3, the inner cavity but the top of the steam sterilization device 1 can be sealed, and the locking mechanism 4 can lock and fix one side of the sealing cover 3 to achieve the first locking effect on the sealing cover 3.

[0024] As Figure 4 shown, the first cleaning mechanism 6 includes a first scraper 601, a sliding block 602 and a baffle 603; The first scraper 601 is movably installed on the outer side of the bottom of the placement cylinder 5. The sliding block 602 is slidably connected inside the steam sterilization device 1 and is located on both sides of the first scraper 601. Both sides of the first scraper 601 are fixedly connected to the inner sides of the sliding blocks 602. The baffle 603 is arranged on both sides of the bottom of the first scraper 601. One side of the sliding block 602 is fixedly connected to the mounting block 703.

[0025] Adopting the above solution: by setting the first scraper 601, when the whole mounting block 703 and the sliding block 602 are driven to move downward, the whole first scraper 601 will be driven downward, so that the first scraper 601 can scrape and clean the dirt adhering to the inner wall of the bottom of the steam sterilization device 1.

[0026] As Figure 3As shown, the baffle 603 is adapted to the inner tank of the steam sterilization device 1 below.

[0027] Adopting the above solution: Through the design of the baffle 603, the chute below the sliding block 602 can be shielded and sealed. When the whole baffle 603 moves downward, it can be smoothly inserted into the inner tank of the steam sterilization device 1.

[0028] As Figure 6 shown, a second cleaning mechanism 8 is arranged in the steam sterilization device 1 at the middle part below the placing cylinder 5. The second cleaning mechanism 8 includes a second scraper 801, a driven bevel gear rod 802, a driving bevel gear rod 803 and a driven gear 804; The second scraper 801 is movably installed at the bottom of the placing cylinder 5. The driven bevel gear rod 802 is movably sleeved inside the bottom end of the steam sterilization device 1, and the top end is fixedly sleeved with the second scraper 801. The driving bevel gear rod 803 is movably sleeved inside the steam sterilization device 1 and is located on one side of the driven bevel gear rod 802. The bottom of the driven bevel gear rod 802 meshes with the side surface of the driving bevel gear rod 803. The driven gear 804 is fixedly sleeved on the other end surface of the driving bevel gear rod 803.

[0029] Adopting the above solution: By setting the driving bevel gear rod 803, when the driven gear 804 and the driving bevel gear rod 803 are driven to rotate as a whole, the teeth on the side surface of the driving bevel gear rod 803 will drive the teeth on the bottom surface of the driven bevel gear rod 802, and the whole driven bevel gear rod 802 and the second scraper 801 will be driven to rotate.

[0030] As Figure 6 shown, the surfaces of the driven gear 804 and the driving gear 702 mesh with each other.

[0031] Adopting the above solution: By setting the driven gear 804, when the driving motor 701 runs to drive the driving gear 702 to rotate, the gear on the surface of the driving gear 702 can drive the gear on the surface of the driven gear 804, and the whole driven gear 804 is driven to rotate.

[0032] As Figure 3 shown, a vibration mechanism 9 is arranged in the steam sterilization device 1 below the other side of the first scraper 601. The vibration mechanism 9 includes a first hydraulic tank 901, a first hydraulic piston rod 902, a second hydraulic tank 903, a transmission assembly 904 and a circular groove 905; The first hydraulic tank 901 is opened inside the steam sterilization device 1 and is located below the other side of the first scraper 601. The first hydraulic piston rod 902 is movably installed in the inner cavity of the first hydraulic tank 901. The second hydraulic tank 903 is opened inside the steam sterilization device 1 and is located below the first hydraulic tank 901. The transmission assembly 904 is arranged inside the second hydraulic tank 903. The second hydraulic tank 903 is fixedly communicated with the first hydraulic tank 901 through a circular groove 905.

[0033] With the above scheme: By providing the first hydraulic piston rod 902, when the whole sliding block 602 moves downward, it will push the whole first hydraulic piston rod 902 downward, and then the hydraulic oil at the bottom of the inner cavity of the first hydraulic tank 901 can be pushed through the circular groove 905 into the inner cavity on one side of the second hydraulic tank 903.

[0034] As Figure 3 shown, the transmission assembly 904 includes a second hydraulic piston rod 9041, a return spring 9042, a transmission arm 9043 and a vibration top frame 9044; The second hydraulic piston rod 9041 is movably installed in the inner cavity of the second hydraulic tank 903. The second hydraulic piston rod 9041 is elastically connected to the inner cavity of the second hydraulic tank 903 through the return spring 9042. The transmission arm 9043 is hinged to one side of the second hydraulic piston rod 9041. The vibration top frame 9044 is movably installed at the bottom of the steam sterilization device 1 and is located directly below the first scraper 601. The other end of the transmission arm 9043 is hinged to one side of the bottom of the vibration top frame 9044.

[0035] With the above scheme: By providing the vibration top frame 9044, when hydraulic oil enters one side of the second hydraulic tank 903, it will push the second hydraulic piston rod 9041 to move to one side, enabling the transmission arm 9043 to push the whole vibration top frame 9044 upward, so that the top of the vibration top frame 9044 can smoothly hit the bottom of the first scraper 601. Then, through the elastic force release of the return spring 9042, the whole second hydraulic piston rod 9041 can be pushed to reset.

[0036] As Figure 5 shown, a sewage pipe valve 10 is fixedly communicated with the bottom on the other side of the steam sterilization device 1.

[0037] With the above scheme: When the first scraper 601 scrapes the scale in the inner cavity of the bottom of the steam sterilization device 1, and after the second scraper 801 rotates to scrape off the scale at the bottom of the placing cylinder 5, clean water can be injected into the steam sterilization device 1 to carry the dirt and discharge it together through the sewage pipe valve 10.

[0038] The working principle and usage process of the present invention: First, the operator can pull the top of the locking mechanism 4 to release the first locking effect on the sealing cover 3, then rotate the top of the sealing cover 3 to release the second locking effect, and then the sealing cover 3 can be rotated horizontally to open. Place the placing cylinder 5 inside the steam sterilization device 1, and inject an appropriate amount of water into the steam sterilization device 1. Place the ampoule bottle containing the potassium hydrogen phosphate injection (loaded by the sterilization tray) at the bottom of the placing cylinder 5. Finally, rotate the sealing cover 3 to close it and fix and seal the sealing cover 3. At this time, the overall steam sterilization device 1 can be controlled through the control panel 2 to perform real-time heating temperature control on the inside of the steam sterilization device 1, so that the high-temperature steam fully disinfects and sterilizes the potassium hydrogen phosphate injection.

[0039] Then, when the sterilization is completed, the drive motor 701 can be started. Due to the operation of the drive motor 701, the driving gear 702 can be driven to rotate. At this time, the linkage shaft 704 will slide on the inner wall of the mounting block 703, thereby driving the mounting block 703, the sliding block 602, the first scraper 601 and the baffle 603 to move downward as a whole. At this time, the first scraper 601 can be used to clean the dirt adhering to the inner wall of the bottom of the steam sterilization device 1 downward. When the driving gear 702 rotates, due to the meshing relationship between the surfaces of the driving gear 702 and the driven gear 804, the driving bevel gear rod 803 can be driven to rotate synchronously. Then, due to the meshing relationship between the driving bevel gear rod 803 and the driven bevel gear rod 802, finally the driven bevel gear rod 802 and the second scraper 801 will rotate as a whole, so that the second scraper 801 pre-scrapes the impurities adhering to the bottom of the placing cylinder 5.

[0040] Finally, when the whole sliding block 602 moves to the bottommost position, it will push the first hydraulic piston rod 902 downward as a whole, so that the hydraulic oil in the bottom inner cavity of the first hydraulic groove 901 enters the second hydraulic groove 903 through the round groove 905. Since the hydraulic pressure in the outer inner cavity of the second hydraulic groove 903 increases, the second hydraulic piston rod 9041 can be pushed to move to one side. Then, the transmission arm 9043 will deflect to push the vibration top frame 9044 to move upward as a whole. Finally, the top of the vibration top frame 9044 just contacts and impacts the bottom of the first scraper 601, so that the remaining part of the dirt at the bottom of the sliding block 602 can be fully shaken off. Subsequently, an appropriate amount of clean water can be injected into the steam sterilization device 1 to wash the dirt and completely discharge it through the sewage pipe valve 10.
