[0002] Currently, smart dispensing machines on the market are primarily developed to address the contamination risks associated with air and hand contact during intravenous drug preparation. These devices are typically used to prepare powder injections and saline solutions. However, in real-world clinical practice, not only powder injections are used, but also aqueous injections dispensed via ampoules.

[0003] Patent publication number CN113797093B discloses an ampoule dispensing system and method, which includes a storage container for loading multiple ampoules and a first disinfection device, a bottle cutting device, a second disinfection device, a bottle breaking device, a discharge mechanism, and a dispensing device arranged in sequence.

[0004] However, the above-mentioned dispensing system still has certain defects when in use. In the existing technology, although the ampoules are disinfected many times, the broken ampoules are often stored in a recycling box and need to be cleaned by medical staff in time. However, when the medical staff forget to clean them due to negligence, the residual liquid medicine in the ampoule, especially the vaccine liquid medicine, will breed bacteria. Especially when there is a day between two dispensings, the next dispensing work will often be affected by the growth of bacteria. Summary of the Invention

[0023] 3. The present invention provides a fan-shaped groove, and the alcohol that enters the fan-shaped groove is then sprayed on the recessed part of the ampoule bottle through the atomizing nozzle. At this time, the medical staff will not let go until the clamping block stably clamps the ampoule bottle. Through the spraying of alcohol, part of the alcohol will also be sprayed on the hands of the medical staff to disinfect the hands of the medical staff. When the medical staff takes the next ampoule bottle, cross infection of bacteria on the surface of the ampoule bottle can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] As a further implementation scheme of the present invention, four micro water pumps 39 are fixedly connected to the bottom of the alcohol tank 29, and the output end of the micro water pump 39 is connected to the second built-in tube 26, and the end of the second built-in tube 26 away from the micro water pump 39 is connected to the second U-shaped tube 34, and the connection between the two is located in the middle section of the second U-shaped tube 34, and the two ends of the second U-shaped tube 34 are respectively connected to the second telescopic tube 36, and the end of the second telescopic tube 36 away from the second U-shaped tube 34 passes through the wall panel of the clamping block 4 and is connected to the water bag 27, and the two ends of the same second U-shaped tube 34 are respectively connected to the water bags 27 arranged on the two clamping blocks 4 located on the same side of the turntable 3, and a one-way water pressure valve is arranged inside the second built-in tube 26.

[0050] In a specific implementation, the one-way water pressure valve is provided with a water pressure preset value, which is used to detect the water pressure on the side of the second built-in tube 26 close to the second U-shaped tube 34. When the water pressure on the side of the second built-in tube 26 close to the second U-shaped tube 34 reaches the water pressure preset value, the one-way water pressure valve opens, and the one-way water pressure valve can only allow the alcohol in the micro water pump 39 to flow into the second U-shaped tube 34.

[0051] As a further embodiment of the present invention, a circular groove 24 is opened in the inner top wall plate of the rotating table 3, and the circular groove 24 is connected to four first built-in tubes 25.

[0052] In a specific implementation, the one-way pressure valve is provided with a preset pressure value. The one-way pressure valve is used to detect the alcohol pressure in the water bag 27. When the alcohol pressure reaches the preset pressure value, the one-way pressure valve opens; otherwise, the one-way pressure valve closes. A pressure valve is also provided inside the flow valve, and the pressure valve is also provided with a preset pressure value, which is the same as the preset pressure value of the one-way pressure valve.

[0053] It should be noted that the water pressure preset value of the one-way water pressure valve is lower than the pressure preset value of the one-way pressure valve, and the one-way water pressure valve is mainly used to replenish alcohol to the water bag 27 .

[0054] As a further implementation scheme of the present invention, the top of the circular groove 24 is connected to a vertical pipe 23, and an empty groove 21 is opened in the top wall panel of the protective cover 2. An electromagnetic three-way valve 20 is arranged inside the empty groove 21. The electromagnetic three-way valve 20 is a one-inlet and two-outlet three-way valve. The end of the vertical pipe 23 away from the rotating table 3 is rotatably connected to the input end of the electromagnetic three-way valve 20, and a seal is provided at the rotating connection between the two. The two output ends of the electromagnetic three-way valve 20 are respectively connected to the empty groove 21 and the external delivery pipe 8.

Both sides of the empty groove 21 are connected to disinfection components, and the two disinfection components are respectively used to disinfect the bottle cap collection box 10 and the bottle body collection box 11.

[0055] In a specific implementation, the seal provided at the rotating sleeve joint between the electromagnetic three-way valve 20 and the vertical pipe 23 is mainly used to prevent leakage at the connection between the two when the vertical pipe 23 rotates with the rotating platform 3. This technology is an existing technology and will not be disclosed in detail here.

[0056] As a further implementation scheme of the present invention, the disinfection component includes a built-in connecting pipe 22 respectively opened in the wall panels on both sides of the protective cover 2, one end of the built-in connecting pipe 22 is connected to the empty slot 21, and a leakage port is opened on the workbench 1 at positions on both sides of the rotating column 16. The bottle cap collection box 10 and the bottle body collection box 11 are respectively connected to the two leakage ports, and the bottle cap collection box 10 and the bottle body collection box 11 are detachably installed at the bottom of the workbench 1, and a transverse groove 31 is provided on the side away from each other of the two leakage ports. The transverse groove 31 is opened inside the workbench 1, and the top of the transverse groove 31 is connected to one end of the built-in connecting pipe 22 away from the empty slot 21, and the side of the transverse groove 31 close to the leakage port is connected to multiple liquid outlet nozzles 32, and the liquid outlet nozzles 32 are arranged on the wall panel on the side of the leakage port away from the rotating column 16.

[0057] In a specific implementation, when the alcohol in the empty groove 21 flows into the transverse groove 31, some alcohol will remain in the transverse groove 31. By utilizing the volatile characteristics of alcohol, when the device is not used, the residual alcohol in the transverse groove 31 can continue to evaporate, and the bottle cap collection box 10, the bottle body collection box 11 and the inside of the protective cover 2 can also be disinfected, which is beneficial to ensure a relatively sterile environment when the device is not in use.

[0058] As a further embodiment of the present invention, a peristaltic pump 12 is fixedly connected to the protective cover 2, and the peristaltic pump 12 is fixedly connected to the side of the extraction port on the protective cover 2.

By driving the needle to move, the needle can be inserted into or removed from the infusion bottle, avoiding manual contact with the infusion bottle. At the same time, an electric slider can be added to the inside of the infusion bottle placement block 13. The electric slider can slide to push the infusion bottle off the infusion bottle placement block 13. At this time, the sliding cover 7 is opened to allow the infusion bottle to fall into the sterile storage box 6. It should be noted that during the process of opening the sliding cover 7, the alcohol concentration in the sterile storage box 6 will decrease, and therefore it needs to be replenished.

[0061] A discharge door panel is hinged on one side of the bottom of the sterile storage box 6, and a sealing strip is provided at the connection between the two. The infusion bottles inside can be taken out by opening the discharge door panel.

[0062] The alcohol concentration monitoring sensor 5 is internally provided with a built-in controller. Communication is established between the alcohol concentration monitoring sensor 5, the built-in controller, and the electromagnetic three-way valve 20. The alcohol concentration monitoring sensor 5 is configured with a maximum concentration preset value and a minimum concentration preset value. When the alcohol concentration in the sterile storage tank 6 reaches the maximum concentration preset value of the alcohol concentration monitoring sensor 5, the alcohol concentration monitoring sensor 5 sends a first request message back to the built-in controller. Upon receiving the first request message, the built-in controller generates a first control message and then sends the first control message to the electromagnetic three-way valve 20, causing the electromagnetic three-way valve 20 to connect the standpipe 23 with the empty slot 21. When the alcohol concentration in the sterile storage tank 6 reaches the minimum concentration preset value of the alcohol concentration monitoring sensor 5, the alcohol concentration monitoring sensor 5 sends a second request message back to the built-in controller. Upon receiving the second request message, the built-in controller generates a second control message and then sends the second control message to the electromagnetic three-way valve 20, causing the electromagnetic three-way valve 20 to connect the standpipe 23 with the external delivery pipe 8.

The two clamping blocks 4 located on the same side of the turntable 3 are respectively fixedly connected to the two driving sliders. A "U"-shaped adjustment member 38 is slidably connected at the center of the four sides of the turntable 3. One of the vertical ends of the adjustment member 38 is slidably sleeved in the side wall panel of the turntable 3, and the other vertical end of the adjustment member 38 is located at the center between the two clamping blocks 4.

[0066] In practice, the height of the adjustment member 38 is adjustable to support ampoules of varying sizes. It also helps align the recess of ampoules of varying sizes with the cutting ring 19, facilitating subsequent cutting and breaking. The adjustment member 38 is slidably connected to one end of the rotating platform 3, providing a tight fit. In the absence of external force, the adjustment member 38 remains stationary relative to one side of the rotating platform 3.

[0067] Working principle of the present invention:

[0068] When the two clamping blocks 4 are close to each other, the water bag 27 between the clamping blocks 4 will abut against the ampoule bottle, and then the alcohol in the water bag 27 will be squeezed. After the alcohol is squeezed, the water pressure in the water bag 27 increases, and then the one-way pressure valve and the flow valve are opened, and the flow valve will quantitatively transport one milliliter of alcohol into the fan-shaped groove 37. The alcohol entering the fan-shaped groove 37 will then be sprayed onto the recessed part of the ampoule bottle through the atomizing nozzle 28. At this time, the medical staff's hand will not let go before the clamping block 4 stably clamps the ampoule bottle. Through the spraying of alcohol, a part of the alcohol will also be sprayed on the medical staff's hand, disinfecting the medical staff's hand, and when the medical staff takes the next ampoule bottle, cross infection of bacteria on the surface of the ampoule bottle can be effectively avoided.

[0069] By spraying alcohol on the concave part of the ampoule bottle, the opening part of the ampoule bottle can be effectively sterilized and disinfected, and alcohol has a certain volatility. During the volatilization process, the alcohol can also perform the overall disinfection work on the internal space of the protective cover 2 to ensure the relative sterility of the environment inside the protective cover 2. At the same time, it can also disinfect the hands of medical staff. During the normal placement of the ampoule bottle, due to the complex hospital environment, it often comes into contact with some bacteria or germs. If effective disinfection is not performed, there is a certain risk of hospital infection. Although medical staff usually wear disposable medical gloves, there is also the situation where cross infection occurs due to negligence and forgetting to disinfect. Therefore, by spraying alcohol, on the one hand, the outer surface of the ampoule bottle can be disinfected, and on the other hand, the hands of medical staff can also be disinfected at the same time, which is conducive to avoiding cross infection on the surface of the ampoule bottle due to medical staff's negligence and forgetting to disinfect their hands, which in turn causes bacteria to contaminate the medicine in subsequent dispensing work.

[0070] After the flow valve has delivered one milliliter of alcohol, the excess alcohol in the water bag 27 will enter the first telescopic tube 35 through the one-way pressure valve, and then enter the circular groove 24 through the first U-shaped tube 33 and the first built-in tube 25, waiting for subsequent disinfection of the bottle cap collection box 10, the bottle body collection box 11 and the sterile storage box 6.

[0071] After the ampoule is fixed, the servo motor 9 is controlled to drive the rotating column 16 to rotate ninety degrees, so that the rotating column 16 drives the rotating table 3 to rotate, and then the clamping block 4 containing the ampoule is transported to the side of the rotating table 3 close to the air bag 17. In this process, the ampoule will come into contact with the cutting ring 19 during the rotation, and the cutting ring 19 will cut a scratch on the side of the ampoule close to the center of the rotating table 3, thereby facilitating the subsequent breaking of the ampoule. After the servo motor 9 rotates ninety degrees, the sliding seat is controlled The first electric telescopic rod at the bottom of 14 is extended, so that the bottle opening ring 18 is sleeved on the top of the ampoule bottle, and then the first electric telescopic rod is controlled to slide on the sliding seat 14 toward the direction close to the air bag 17, so that the bottle opening ring 18 pries open the ampoule bottle. After the ampoule bottle is pried open, the bottle cap of the ampoule bottle will bounce on the air bag 17. Through the setting of the air bag 17, the bottle cap of the ampoule bottle can be effectively relieved, so that the ampoule bottle can smoothly fall into the bottle cap collection box 10, so as to realize the collection of the ampoule bottle cap.

[0072] After the ampoule is broken open, the servo motor 9 drives the rotating column 16 to rotate another 90 degrees. During this process, the first electric telescopic rod shrinks and slides to the initial position on the sliding seat 14, waiting for the next ampoule to be broken. After the servo motor 9 rotates again, the broken ampoule will be transported to the extraction port. Prior to this, a disposable drug extraction needle is added to the peristaltic pump 12, and the needle at one end of the needle is inserted into the infusion bottle. The infusion bottle is then placed on the infusion bottle placement block 13, and the needle at the other end of the needle is clamped on the needle clamp 15. The second electric telescopic rod is controlled to extend, thereby driving the needle to descend. After the needle descends into the ampoule, the peristaltic pump 12 is used to extract the liquid medicine. After the liquid medicine is extracted, the second electric telescopic rod shrinks to reset the needle. It should be noted that, during the evaporation of the alcohol inside the protective cover 2, the alcohol can also disinfect the needle, which is helpful to avoid cross infection of the needle.

[0073] After the liquid medicine is extracted, the servo motor 9 is controlled to rotate ninety degrees for the third time. At this time, the ampoule with the liquid medicine extracted is transported to the top of the bottle collection box 11. At this time, the clamping blocks 4 move away from each other, thereby causing the clamping blocks 4 to loosen their grip on the ampoule, causing the ampoule to fall into the bottle collection box 11 under the action of gravity. When the clamping blocks 4 move away from each other, the micro water pump 39 is turned on. After being turned on, the micro water pump 39 draws alcohol from the alcohol tank 29, then transports it to the second U-shaped tube 34 through the second built-in tube 26, and finally transports it to the water bag 27 through the second telescopic tube 36 to replenish the water bag 27 with alcohol. When the one-way water pressure valve in the water bag 27 senses that the water pressure in the second built-in tube 26 has reached its preset value, the micro water pump 39 is turned off. It should be noted that the one-way water pressure valve can be used in conjunction with a controller to control the closing of the micro water pump 39. This technology is existing technology and will not be disclosed in detail here. The opening of the micro water pump 39 can be controlled by a switch. The switch can be placed at both ends of the slide. When the two driving sliders in the slide on one side of the rotating table 3 drive the clamping block 4 to move away from each other, the driving slider will abut against the switch, thereby turning on the micro water pump 39 corresponding to the switch to replenish the water bag 27 with alcohol.

[0074] After the ampoule bottle falls into the bottle body collection box 11, the servo motor 9 is controlled to drive the rotating table 3 to rotate 90 degrees, so that the clamping block 4 can be reset, so that the clamping block 4 is located at the placement port, and the ampoule bottle is circulated for dispensing. After the dispensing is completed, the disposable syringe is removed from the peristaltic pump 12, and then the infusion bottle is removed from the infusion bottle placement block 13. At this time, the sliding cover 7 is opened, and the infusion bottle falls into the sterile storage box 6 for temporary storage. Through the mutual cooperation of the servo motor 9, the first electric telescopic rod, the second electric telescopic rod, the peristaltic pump 12 and other components, the automatic opening of the ampoule bottle, the extraction of the liquid medicine and the collection of the ampoule bottle are realized, which greatly improves the efficiency and accuracy of the drug proportioning and dosing process, and also avoids the problems such as cross infection that may be caused by manual operation, thereby ensuring the sterility and safety of the drug proportioning and dosing process.

[0075] After the excess alcohol in the water bag 27 enters the circular groove 24, it will then enter the electromagnetic three-way valve 20 through the vertical pipe 23 at the top of the circular groove 24. At this time, the output end of the electromagnetic three-way valve 20 is connected to the external delivery pipe 8, so that the alcohol is delivered to the receiving nozzle. Finally, the receiving nozzle is used to spray alcohol on the sterile storage box 6 to disinfect the outer surface of the infusion bottle to avoid cross infection during the temporary storage of the infusion bottle.

[0076] The alcohol concentration monitoring sensor 5 monitors the alcohol concentration in the sterile storage box 6 in real time. When the alcohol concentration in the sterile storage box 6 reaches the maximum concentration preset value of the alcohol concentration monitoring sensor 5, the alcohol concentration monitoring sensor 5 feeds back a first request message to the built-in controller. After receiving the first request message, the built-in controller generates a first control message, which is then sent to the electromagnetic three-way valve 20, causing the electromagnetic three-way valve 20 to connect the vertical pipe 23 with the empty slot 21. When the alcohol concentration in the sterile storage box 6 reaches the minimum concentration preset value of the alcohol concentration monitoring sensor 5, the alcohol concentration monitoring sensor 5 feeds back a second request message to the built-in controller. After receiving the second request message, the built-in controller generates a second control message, which is then sent to the electromagnetic three-way valve 20, causing the electromagnetic three-way valve 20 to connect the vertical pipe 23 with the external delivery pipe 8, thereby re-disinfecting the sterile storage box 6 and ensuring the alcohol concentration in the sterile storage box 6 to achieve sterile storage of the infusion bottle.

[0077] When the vertical pipe 23 is connected with the empty groove 21, the alcohol will be transported into the empty groove 21, and then enter the horizontal groove 31 through the built-in connecting pipe 22, and finally sprayed into the bottle cap collection box 10 and the bottle body collection box 11 through the liquid outlet nozzle 32, thereby realizing the disinfection of the bottle cap collection box 10 and the bottle body collection box 11. On the one hand, it can help to avoid the bottle body and bottle cap of the ampoule bottle from being effectively disinfected, and is conducive to the secondary disinfection of the pathogens on the outer surface of the ampoule bottle that are not disinfected by the alcohol sprayed by the atomizing nozzle 28. On the other hand, it can also help to avoid the medical staff from forgetting to take away the bottle cap and bottle body of the ampoule bottle in the bottle cap collection box 10 and the bottle body collection box 11 due to being too tired, thereby causing the pathogens to multiply in the bottle cap collection box 10 and the bottle body collection box 11, which is conducive to maintaining the relative sterility of the device.

[0078] By utilizing alcohol to achieve the disinfection work before the ampoule bottle is broken, cross infection of pathogens on the surface of the ampoule bottle is avoided. By utilizing the electromagnetic three-way valve 20 and the alcohol concentration monitoring sensor 5, the bottle body and bottle cap of the ampoule bottle after breaking can be disinfected for a second time, and the situation that pathogens are propagated in the bottle cap collection box 10 and the bottle body collection box 11 can also be avoided, further ensuring the sterile environment of the device. In addition, the electromagnetic three-way valve 20 and the alcohol concentration monitoring sensor 5 can also disinfect the infusion bottle after the dispensing is completed, avoiding the situation that cross infection occurs on the surface of the infusion bottle, further ensuring the sterility of the dispensing. By delivering alcohol, the multiple disinfection work of the ampoule bottle dispensing can be effectively achieved, ensuring the sterile environment of the dispensing, avoiding the situation that cross infection occurs, and also helping to solve the situation that the disinfection is not thorough due to the negligence of medical staff.
