Description

Technical Field

[0001] This utility model relates to the field of automatic drug dispensing, and in particular to an air extraction structure for a liquid bag dispensing machine. Background Technology

[0002] In the field of automated drug dispensing, there is the issue of dispensing liquid bags, which involves corresponding liquid bag dispensing mechanisms. Typically, a liquid bag dispensing structure has a receiving cavity. The dispensed liquid bag is placed into the receiving cavity, and after the liquid in the bag is completely extracted, the staff removes the liquid bag from the receiving cavity.

[0003] In related technologies, in order to further improve the discharge efficiency of liquid bags, some liquid bag discharge mechanisms are designed to divide the receiving cavity into two chambers and add a rotating mechanism. After the liquid bag is put into one chamber and used, the rotating mechanism can be used to rotate the chamber to the other side to remove the liquid bag. At the same time, the other chamber continues to be filled with liquid bags. In this way, the discharge efficiency of liquid bags can be greatly improved.

[0004] While this method can improve the discharge efficiency of the liquid bag, when preparing certain drugs, the drugs may contain some toxic gases or aerosols. During the automatic dispensing and drug preparation process, due to the sealing problem of the liquid bag, the toxic gases or aerosols inside the liquid bag may leak out, threatening the personal safety of the operators. Utility Model Content

[0005] The purpose of this invention is to provide an air extraction structure for a liquid bag discharge machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum structure for a liquid bag discharge machine, comprising a fixed base, a storage body mounted on the fixed base, and a rotating platform located inside the storage body and rotatably connected to the fixed base. The rotating platform is provided with a partition for use in conjunction with the storage body to individually limit the position of each liquid bag. At least two partitions are provided, and each partition has a vacuum hole on one side facing the center line of the rotating platform. A vacuum mechanism is provided at the center of the rotating platform.

[0007] By adopting the above technical solution, a rotating platform is set inside the storage body, and at least two baffles are set on the rotating platform to work with the storage body to individually limit each liquid bag. The baffles effectively prevent the liquid bags from tipping over and covering the suction mechanism during operation, thus preventing the suction mechanism from working properly. If the liquid bag in the containment cavity ruptures and leaks toxic gas, the suction hole opened on the side of the baffle facing the center line of the rotating platform will discharge the toxic gas through the suction mechanism which is connected to the external fluid. The suction mechanism is set in the suction chamber and close to the suction hole, so that the toxic gas in the suction chamber can be discharged more quickly, improving the working efficiency of the equipment.

[0008] Preferably, adjacent partitions are connected to each other to form an air extraction chamber between the inner sides of the partitions and a receiving chamber for placing the liquid supply bag between the outer sides of the partitions and the storage body.

[0009] By adopting the above technical solution, a receiving cavity for accommodating liquid bags will be formed between the outer surface of the partition and the inner surface of the storage body, corresponding to the number of partitions. Setting at least two partitions corresponds to at least two receiving cavities for accommodating liquid bags. After a liquid bag is put into one receiving cavity, it can be removed from the other side by rotating the rotating platform. The other cavity will also continue to be filled with liquid bags, which greatly improves the efficiency of liquid bag discharge. At the same time, since the adjacent partitions are connected to each other, the toxic gases and other substances brought by the liquid bags in the receiving cavities can only flow into the suction cavity through the suction hole located on one side of the partition.

[0010] Preferably, the air extraction chamber has expansion chambers at both ends, which are formed by extending outward from both sides of the partition.

[0011] By adopting the above technical solution, the expansion cavity formed by extending the two sides of the partition outward will have a larger capacity to store more toxic gases, thereby giving the extraction mechanism more processing time to discharge the toxic gases and improve the safety of the device.

[0012] Preferably, the air extraction mechanism is configured as an air extraction pipe, with one side of the air extraction pipe in fluid communication with an external suction receiving device and the other side in fluid communication with the air extraction chamber and in fluid communication with the receiving chamber through the air extraction hole.

[0013] By adopting the above technical solution, after the liquid bag is inserted, the external suction and containment device starts the suction state. After the suction is started, the suction chamber will show a negative pressure state. The toxic gas in the containment chamber enters the suction chamber through the suction hole under the suction force. The toxic gas in the suction chamber enters the suction mechanism under the further guidance of the suction force and is discharged to the external suction and containment device through the suction mechanism.

[0014] Preferably, the rotating platform includes a turntable fixedly connected to the bottom side of the partition, a rotary connector rotatably connected to the top of the turntable, a driving component fixedly connected to the bottom of the rotary connector, and the driving component rotatably connected to the turntable through the rotary connector.

[0015] By adopting the above technical solution, the drive unit is first connected to an external power source and started. After the liquid bag is put into one of the receiving cavities, the drive unit drives the turntable to rotate through the rotary connector. Then, the turntable drives the partition fixedly connected to the top surface of the turntable to rotate together, transporting the liquid bag in the receiving cavity to the other side, where it is then removed by the staff.

[0016] Preferably, the rotary connector includes a connector fixedly connected to the fixed base and a rotary component rotatably sleeved with the connector, the rotary component being rotatably connected to the turntable.

[0017] By adopting the above technical solution, the driving component transmits rotational power to the rotating component through the connecting component, and then the rotating component drives the turntable to rotate. In this way, the turntable drives the partition plate fixedly connected to the top surface of the turntable to rotate together, transporting the liquid bag located in the receiving cavity to the other side.

[0018] Preferably, the top surface of the driving component is provided with a position detection module, and the detection end of the position detection module can intersect with the outer surface of the sensor sheet fixedly connected to one side of the rotating component.

[0019] By adopting the above technical solution, the position detection module detects the position of the rotating part through the sensor plate and then detects the position of the partition based on the position of the rotating part. When the sensor plate on the rotating connector intersects with the detection end of the position detection module, the drive unit pauses power output and waits for the liquid bag to be placed into the receiving cavity before the drive unit continues to output power to drive the turntable to rotate through the rotating connector.

[0020] Preferably, the position detection module is electrically connected to the driving component and infrared connected to the sensing sheet.

[0021] By adopting the above technical solution, whenever the sensor plate on the rotary connector intersects with the detection end of the position detection module, the infrared signal emitted by the detection end of the position detection module will be blocked by the sensor plate. At the same time, a signal is output to the drive unit to control the drive unit to pause the power output for a preset time. After the preset time is reached and the liquid bag is placed into the receiving cavity, the drive unit continues to output power to drive the turntable to rotate through the rotary connector, and transport the liquid bag to the other side for the staff to take it out.

[0022] Preferably, the storage body is provided with an inlet for receiving liquid bags and an outlet for discharging liquid bags.

[0023] By adopting the above technical solution, the storage body is configured to have an input port for receiving the liquid bag after the medicine is prepared and an output port for the staff to take out the liquid bag. During operation, the liquid bag is put into the receiving cavity from the input port side of the storage body. The rotating platform rotates and drives the partition plate fixedly connected to the rotating platform to rotate, so that the liquid bag in the receiving cavity follows the partition plate to the other side and is taken out by the staff.

[0024] Preferably, the partitions are symmetrically arranged, with the input port perpendicular to the input port of the storage body and the output port parallel to the output port of the storage body.

[0025] By adopting the above technical solution, the partitions are symmetrically arranged and the ports of the partitions correspond to the ports of the storage body, which facilitates the handling of mechanical equipment or personnel and improves work efficiency.

[0026] Preferably, a safety detection unit is provided inside the output port of the storage body, and the safety detection unit is electrically connected to the rotating platform.

[0027] By adopting the above technical solution, when the liquid bag is delivered to the inlet of the storage body, the drive unit pauses power output for a preset time. When the worker puts his hand in from the outlet port of the storage body to take it out, the safety detection unit detects whether the hand is still inside the storage body. If a hand is detected, it sends a signal to the position detection module on the rotating platform to control the drive unit to continue to stop power output, and the rotating platform does not move, thus improving the safety of the device.

[0028] Preferably, an even number of liquid bag sensing units are arranged around the top surface of the fixed base, and the liquid bag sensing units are electrically connected to the rotating platform.

[0029] By adopting the above technical solution, multiple liquid bag sensing units arranged in a ring are used to detect whether there are liquid bags in the containment cavity.

[0030] Preferably, the bottom of the partition is provided with through holes matching the number of liquid bag sensing units, and the positions of the through holes correspond one-to-one with the detection end positions of the liquid bag sensing units.

[0031] By adopting the above technical solution, through holes corresponding to the number of sensing units are set, and the positions of the through holes correspond one-to-one with the positions of the sensing units' detection ends, which facilitates the passage of light by the liquid bag sensing units and improves the accuracy of detection.

[0032] Preferably, the top surface of the storage body is provided with a first baffle and a second baffle located on both sides of the input port, and a guide rod disposed between the two baffles.

[0033] By adopting the above technical solution, when the liquid bag is delivered into the storage body through the mechanical equipment, the first baffle and the second baffle prevent the liquid bag from getting stuck on the wall or even leaking due to different postures during the falling process, which would affect the falling efficiency and personnel safety. The guide rod is set to assist the liquid bag in detaching from the robot and to guide the position of the liquid bag.

[0034] Preferably, a guide plate located on one side of the input port is provided on the same side of the first baffle and the second baffle, and a limit plate is also provided on the other side of the first baffle.

[0035] By adopting the above technical solution, the guide plate set on the same side limits and guides the position and posture of the liquid bag when it enters from the side, and corrects the position and posture of the liquid bag to ensure accurate delivery of the liquid bag.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. An air extraction chamber is added to the liquid bag discharge mechanism. If the liquid bag in the containment chamber ruptures and leaks toxic gas, the external suction containment device will activate the air extraction state. The toxic gas in the containment chamber will be guided by suction and enter the air extraction chamber and expansion chamber through the air extraction hole. The toxic gas in the air extraction chamber and expansion chamber will be further guided by suction and enter the air extraction mechanism and be discharged to the external suction containment device, thereby improving the safety of the drug preparation process.

[0038] 2. The device employs a unique partition design to form an air extraction chamber and symmetrically divides the liquid bag placement area, giving it at least two cavities for accommodating liquid bags. This improves safety while maintaining production efficiency. Attached Figure Description

[0047] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0048] Please see Figures 1-2 This application discloses a vacuuming structure for a liquid bag discharge machine, including a fixed base 1, a storage body 2 installed on the fixed base 1, and a rotating platform 3 located inside the storage body 2 and rotatably connected to the fixed base 1. The rotating platform 3 is provided with a partition 5 for use in conjunction with the storage body 2 to individually limit each liquid bag 4. At least two partitions 5 are provided. The partitions 5 have a vacuuming hole 51 on one side facing the center line of the rotating platform 3. The rotating platform 3 is provided with a vacuuming mechanism 6 at its center.

[0049] See Figure 1 and Figure 6 In this embodiment, a rotating platform 3 is provided inside the storage body 2. At least two partitions 5 are provided on the rotating platform 3 to work with the storage body 2 to individually limit each liquid bag 4. The partitions 5 effectively prevent the liquid bags 4 from tipping over and covering the suction mechanism 6 during operation, which would cause the suction mechanism 6 to malfunction. If the liquid bag 4 located in the containment cavity ruptures and leaks toxic gas, the suction hole 51 opened on the side of the partition 5 facing the center line of the rotating platform 3 will discharge the toxic gas through the suction mechanism 6 which is connected to the external fluid. The suction mechanism 6 is set in the suction chamber 7 and close to the suction hole 51 so that the toxic gas in the suction chamber 7 can be discharged faster, thereby improving the working efficiency of the equipment.

[0050] See Figure 1 and Figure 3In this embodiment, adjacent partitions 5 are interconnected to form an air extraction chamber 7 between the inner sides of the partitions 5, and a receiving chamber for placing liquid bags 4 is formed between the outer side of the partitions 5 and the storage body 2. This creates receiving chambers for holding liquid bags 4 corresponding to the number of partitions 5 between the outer surface of the partitions 5 and the inner surface of the storage body 2. Setting at least two partitions 5 corresponds to at least two receiving chambers for holding liquid bags 4. After a liquid bag 4 is placed in one receiving chamber, it can be rotated to the other side by the rotating platform 3, and another chamber can continue to be filled with liquid bags 4, greatly improving the efficiency of liquid bag 4 discharge. Simultaneously, because the adjacent partitions 5 are interconnected, toxic gases and other contaminants from the liquid bags 4 within the receiving chambers can only flow into the air extraction chamber 7 through the air extraction hole 51 located on one side of the partition 5.

[0051] See Figure 1 and Figure 6 In this embodiment, the two ends of the extraction chamber 7 are provided with expansion chambers 8. The expansion chambers 8 are formed by extending outward from both sides of the partition 5. The expansion chambers 8 formed by extending outward from both sides of the partition 5 will have a larger capacity to store more toxic gas, thereby giving the extraction mechanism 6 more processing time to discharge the toxic gas and improve the safety of the device.

[0052] See Figure 1 and Figure 3 In this embodiment, the suction mechanism 6 is configured as a suction pipe. One side of the suction pipe is in fluid communication with the external suction and containment device, and the other side is in fluid communication with the suction chamber 7 and is in fluid communication with the containment chamber through the suction hole 51. After the liquid bag 4 is inserted, the external suction and containment device starts the suction state. After the suction is started, the suction chamber 7 will show a negative pressure state. The toxic gas located in the containment chamber enters the suction chamber 7 through the suction hole 51 under the guidance of the suction force. The toxic gas entering the suction chamber 7 enters the suction mechanism 6 under the further guidance of the suction force and is discharged to the external suction and containment device through the suction mechanism 6.

[0053] See Figure 3 and Figure 7 In this embodiment, the rotating platform 3 includes a turntable 31 fixedly connected to the bottom side of the partition 5 and a rotary connector 32 rotatably connected to the top of the turntable 31. A drive component 33 is fixedly connected to the bottom of the rotary connector 32. The drive component 33 is rotatably connected to the turntable 31 through the rotary connector 32. The drive component 33 is first connected to an external power source to start. After the liquid bag 4 is put into one side of the receiving cavity, the drive component 33 drives the turntable 31 to rotate through the rotary connector 32. Then, the turntable 31 drives the partition 5 fixedly connected to the top surface of the turntable 31 to rotate together, transporting the liquid bag 4 located in the receiving cavity to the other side. Then, the staff takes it out. The drive component 33 is set as a drive motor and is connected to an external power source through the motor wire 331.

[0054] See Figure 3 and Figure 7 In this embodiment, the rotary connector 32 includes a connector 321 fixedly connected to the fixed base 1 and a rotary component 322 rotatably connected to the connector 321. The rotary component 322 is rotatably connected to the turntable 31. The drive component 33 transmits rotational power to the rotary component 322 through the connector 321, thereby driving the turntable 31 to rotate through the rotary component 322. In this way, the turntable 31 drives the partition 5 fixedly connected to the top surface of the turntable 31 to rotate together, transporting the liquid bag 4 located in the receiving cavity to the other side.

[0055] See Figure 7 In this embodiment, a position detection module 332 is provided on the top surface of the drive component 33. The detection end of the position detection module 332 intersects with the outer surface of the sensor plate 323 fixedly connected to one side of the rotating component 322. The position detection module 332 detects the position of the rotating component 322 through the sensor plate 323 and then detects the position of the partition 5 based on the position of the rotating component 322. When the sensor plate 323 on the rotating connector 32 intersects with the detection end of the position detection module 332, the drive component 33 pauses its power output and waits for the liquid bag 4 to be placed into the receiving cavity before the drive component 33 continues to output power to drive the turntable 31 to rotate through the rotating connector 32.

[0056] See Figure 7 In this embodiment, the position detection module 332 is electrically connected to the drive unit 33 and infrared connected to the sensor plate 323. Whenever the sensor plate 323 on the rotary connector 32 intersects with the detection end of the position detection module 332, the infrared signal emitted by the detection end of the position detection module 332 will be blocked by the sensor plate 323. At the same time, a signal is output to the drive unit 33 to control the drive unit 33 to pause the power output for a preset time. After the preset time is reached and the liquid bag 4 is placed into the receiving cavity, the drive unit 33 continues to output power to drive the turntable 31 to rotate through the rotary connector 32, and transport the liquid bag 4 to the other side for the staff to take it out.

[0057] See Figure 4 and Figure 5 In this embodiment, the storage body 2 is provided with an input port 21 for receiving the liquid bag 4 and an output port 22 for discharging the liquid bag 4. The storage body 2 is configured to have an input port 21 for receiving the prepared liquid bag 4 and an output port 22 for easy removal of the liquid bag 4 by the staff. During operation, the liquid bag 4 is inserted into the receiving cavity from the input port 21 side of the storage body. The rotating platform 3 rotates and drives the partition 5 fixedly connected to the rotating platform 3 to rotate, so that the liquid bag 4 located in the receiving cavity rotates to the other side with the partition 5 and is removed by the staff.

[0058] See Figure 3 and Figure 5In this embodiment, the partitions 5 are symmetrically arranged with the input port perpendicular to the input port 21 of the storage body and the output port parallel to the output port 22 of the storage body. The symmetrical arrangement of the partitions 5 and the corresponding ports to the ports of the storage body 2 facilitate mechanical equipment or workers to perform retrieval operations, thereby improving work efficiency.

[0059] See Figure 5 and Figure 7 In this embodiment, a safety detection unit 23 is provided inside the storage body output port 22. The safety detection unit 23 is electrically connected to the rotating platform 3. Specifically, the safety detection unit 23 is electrically connected to the position detection module 332 on the rotating platform 3. When the liquid bag 4 is delivered to the storage body input port 21, the drive component 33 pauses power output for a preset time. When the worker puts his hand into the storage body output port 22 to take it out, the safety detection unit 23 detects whether the hand is still inside the storage body 2. If a hand is detected, it sends a signal to the position detection module 332 to control the drive component 33 to continue to stop power output. The rotating platform 3 does not move, improving the safety of the device. The safety detection unit 23 is set as a detection grating and is connected to an external power source through a wire 231.

[0060] See Figure 1 and Figure 3 In this embodiment, an even number of liquid bag sensing units 11 are arranged around the top surface of the fixed base 1. The liquid bag sensing units 11 are electrically connected to the rotating platform 3. The multiple liquid bag sensing units 11 arranged around the base are used to detect whether there is a liquid bag 4 in the containment cavity.

[0061] See Figure 1 and Figure 3 In this embodiment, the bottom of the partition 5 is provided with through holes 52 matching the number of liquid bag sensing units 11. The positions of the through holes 52 correspond one-to-one with the positions of the detection ends of the liquid bag sensing units 11. Providing through holes 52 corresponding to the number of liquid bag sensing units 11 and having the positions of the through holes 52 correspond one-to-one with the positions of the detection ends of the liquid bag sensing units 11 facilitates the passage of the sensing light 111 by the liquid bag sensing units 11 and improves the accuracy of detection.

[0062] See Figure 4 and Figure 5 In this embodiment, the top surface of the storage body 2 is provided with a first baffle 24 and a second baffle 25 located on both sides of the inlet 21 port, and a guide rod 26 disposed between the two baffles. When the liquid bag 4 is delivered into the storage body from the inlet 21 port by mechanical equipment, the first baffle 24 and the second baffle 25 prevent the liquid bag 4 from getting stuck on the wall or even leaking due to different postures during the falling process, which would affect the falling efficiency and personnel safety. The guide rod 26 is provided to assist the liquid bag 4 in detaching from the robot and to guide the position of the liquid bag 4.

[0063] See Figure 4 and Figure 5 In this embodiment, the first baffle 24 and the second baffle 25 are provided on the same side of the first guide plate 241 and the second guide plate 251 located on the side of the input port 21. The other side of the first baffle 24 is also provided with a limiting plate 242. The guide plates provided on the same side limit and guide the position and posture of the liquid bag 4 when it enters from the side, and correct the position and posture of the liquid bag 4 to ensure that the liquid bag 4 is accurately delivered.

[0064] The implementation principle of this application embodiment is as follows: A unique partition 5 design is adopted to form a suction chamber 7 and the placement position of the liquid bag 4 is symmetrically divided. Then, a corresponding number of receiving cavities for receiving the liquid bag 4 will be formed between the outer surface of the partition 5 and the inner surface of the storage body 2. After the liquid bag 4 is put into one receiving cavity, it is taken out on the other side by rotating the rotating platform 3. The other cavity is also put into the liquid bag 4. Once the liquid bag 4 in the receiving cavity breaks and leaks toxic gas, the external suction receiving device starts the suction state. The toxic gas in the receiving cavity enters the suction chamber 7 and the expansion chamber 8 through the suction hole 51 under the guidance of the suction. The toxic gas in the suction chamber 7 and the expansion chamber 8 enters the suction mechanism 6 under the further guidance of the suction and is discharged to the external suction receiving device through the suction mechanism 6.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
