[0022] The movable seat 2 is positioned opposite to the first position 5. The movable seat 2 is slidably mounted on the fixed seat 1 along the first direction, which is the direction in which the movable seat 2 faces the first position 5. The movable seat 2 is provided with a third retainer 43 for fixing the injection needle body.
[0023] The vertical drive assembly 4 includes a first drive member 41, a second drive member 42, and a fourth retainer 44; wherein, the first drive member 41 is fixed on the fixed base 1, and the output end of the first drive member 41 is fixedly connected to the movable base 2, which can drive the movable base 2 to reciprocate along the first direction; the second drive member 42 is fixed on the movable base 2, and the output end of the second drive member 42 is fixedly connected to the fourth retainer 44, which can drive the fourth retainer 44 to reciprocate along the first direction; the fourth retainer 44 is used for detachable connection with the injection needle push rod.
[0024] Reference Figure 1 as well as Figure 2 For ease of explanation, a first direction and a second direction are defined. The first direction is the direction in which the movable seat 2 faces the first position 5, which can be understood as the vertical direction in this embodiment. The second direction is the length direction of the fixed seat 1, which can be understood as the horizontal direction in this embodiment. In the accompanying drawings, the first direction is represented by the X direction, and the second direction is represented by the Y direction.
[0025] The fixing base 1 is provided with a first card holder 11 and a second card holder 12. The first card holder 11 is used to fix the infusion bag 7 and the second card holder 12 is used to fix the medicine bottle 6. The fixing base 1 is provided with a first position 5.
[0026] Specifically, a retaining ring 111 is fixed on the first retaining seat 11. The retaining ring 111 is a circular ring with a notch. After the retaining ring 111 undergoes elastic deformation, the notch becomes larger, which can accommodate the bag opening of the infusion bag 7 to enter. The retaining ring 111 can achieve a detachable fixed connection with the infusion bag 7.
[0027] Furthermore, the first card holder 11 is also provided with an elastic band, which can be used to fix the body of the infusion bag 7. The elastic band is not shown in the attached figure.
[0028] The second holder 12 is used to fix the medicine bottle 6 containing powder or liquid medicine. The bottom of the medicine bottle 6 is fixed on the second holder 12, and the mouth of the medicine bottle 6 is located below the second holder 12. A specific method of fixing the medicine bottle 6 with the second holder 12 will be described in detail later.
[0029] The lateral drive assembly 3 drives the first card holder 11 to move and lock into or out of the first position 5, and the lateral drive assembly 3 drives the second card holder 12 to move and lock into or out of the first position 5. The first position 5 is illustrated in the attached drawing using a dashed box.

When the second card holder 12 moves and locks to the first position 5, the position of the medicine bottle 6 is fixed.
[0031] The phrase "moves and locks to or moves out of the first position 5" as described in the description of the lateral drive assembly 3 driving the first card holder 11 to move and lock to or move out of the first position 5 can be understood as follows: the lateral drive assembly 3 can drive the first card holder 11 to move and lock to the first position 5, that is, drive the first card holder 11 to move and fix the first card holder 11 in the first position 5. The lateral drive assembly 3 can also drive the first card holder 11 to move out of the first position 5, that is, move the first card holder 11 to a position other than the first position 5; before the lateral drive assembly 3 drives the first card holder 11 to move and lock to the first position 5, the second card holder 12 needs to be moved out of the first position 5.
[0032] In another embodiment, a fifth card holder is also provided on the fixed base 1. The fifth card holder is used to fix the second type of medicine bottle. The lateral drive component 3 drives the fifth card holder to move and lock it to or move it out of the first position 5.
[0033] In another embodiment, the fixing base 1 is also provided with a fifth card holder and a sixth card holder. The fifth card holder is used to fix the second type of medicine bottle, and the sixth card holder is used to fix the third type of medicine bottle. The lateral drive component 3 drives the fifth card holder to move and lock to or move out of the first position 5, and the lateral drive component 3 drives the sixth card holder to move and lock to or move out of the first position 5.
[0034] The movable seat 2 is positioned opposite to the first position 5. The movable seat 2 is slidably mounted on the fixed seat 1 along the first direction. The movable seat 2 is provided with a third retainer 43 for fixing the injection needle body.
[0035] Specifically, the movable seat 2 is positioned opposite to the first position 5, meaning that the movable seat 2 is positioned opposite to the first retaining seat 11 along the first direction, or opposite to the second retaining seat 12 along the first direction. The third retaining seat 43 is fixed on the movable seat 2 and moves synchronously with the movable seat 2. The third retaining seat 43 is used to fix the body of the injection needle. For example, the structure of the third retaining seat 43 is similar to the structure of the retaining ring 111 used to fix the infusion bag 7.
[0036] The vertical drive assembly 4 includes a first drive member 41, a second drive member 42, and a fourth retainer 44; wherein, the first drive member 41 is fixed on the fixed base 1, and the output end of the first drive member 41 is fixedly connected to the movable base 2, which can drive the movable base 2 to reciprocate along the first direction; the second drive member 42 is fixed on the movable base 2, and the output end of the second drive member 42 is fixedly connected to the fourth retainer 44, which can drive the fourth retainer 44 to reciprocate along the first direction; the fourth retainer 44 is used for detachable connection with the injection needle push rod.
[0037] Specifically, both the first driving component 41 and the second driving component 42 are cylinders and are arranged along the first direction. The first driving component 41 is fixed on the fixed base 1, and the output end of the first driving component 41 is fixedly connected to the movable base 2. The first driving component 41 drives the movable base 2 to reciprocate along the first direction.
[0038] The second driving member 42 is fixed on the movable base 2 and is fixedly connected to the fourth card holder 44. The second driving member 42 drives the fourth card holder 44 to reciprocate along the first direction. The first card holder 11 is used to fix the push rod of the injection needle. Specifically, the first card holder 11 is provided with a connecting groove 123, and the circular piece of the push rod of the injection needle is located in the connecting groove 123.
[0039] The specific steps for using it are as follows:
[0040] Step 1: Fix the infusion bag 7 to the first bracket 11, fix the medicine bottle 6 to the second bracket 12, fix the body of the injection needle to the third bracket 43, and fix the plunger of the injection needle to the fourth bracket 44.
[0041] Step 2: Start the medication dispensing device. The horizontal drive component 3 pushes the first card holder 11 to the first position 5. The first drive component 41 drives the moving seat 2 to push the injection needle toward the first card holder 11. The needle tip of the injection needle is inserted into the infusion bag 7. The second drive component 42 drives the push rod to move away from the infusion bag 7, drawing the liquid in the infusion bag 7 into the injection needle.
[0042] Step 3: The first driving component 41 drives the moving seat 2 to push the injection needle away from the first card seat 11, and the needle tip of the injection needle is removed from the infusion bag 7.
[0043] Step 4: The lateral drive assembly 3 pushes the second card holder 12 to the first position 5. The first drive member 41 drives the moving seat 2 to push the injection needle toward the first card holder 11. The needle tip of the injection needle is inserted into the medicine bottle 6. The second drive member 42 drives the push rod of the injection needle to move toward the medicine bottle 6, injecting liquid into the medicine bottle 6. The second drive member 42 then drives the push rod to move away from the medicine bottle 6, drawing liquid into the injection needle.
[0044] Step 5: The first driving component 41 drives the moving seat 2 to push the injection needle away from the second card seat 12, and the needle tip of the injection needle is removed from the medicine bottle 6.
[0045] Step 6: The lateral drive assembly 3 pushes the first card holder 11 to the first position 5. The first drive member 41 drives the moving seat 2 to push the injection needle toward the first card holder 11. The needle tip of the injection needle is inserted into the infusion bag 7. The second drive member 42 drives the push rod of the injection needle to move toward the infusion bag 7, injecting liquid into the infusion bag 7.
[0046] Furthermore, the above steps can be repeated to reduce the amount of medication residue in the medicine bottle 6.
[0047] Furthermore, by controlling the position of the needle inserted into the medicine bottle 6, the amount of remaining medicine in the medicine bottle 6 can be reduced.
[0048] In another embodiment, the dispensing device further includes a fifth card holder and a sixth card holder. The second card holder 12, the fifth card holder and the sixth card holder respectively fix a medicine bottle 6. The above steps are not limited to configuring a medicine bottle 6. The fifth card holder and the sixth card holder can also be moved to the first position to configure multiple medicine bottles.
[0049] When using this device, medical staff only need to fix the medicine bottle 6, infusion bag 7 and injection needle in the appropriate position, and the drug dispensing device will automatically complete the drug dispensing operation, which simplifies the drug dispensing process, improves drug dispensing efficiency, reduces the error rate of drug dispensing, and reduces drug waste caused by drug dispensing.
[0050] Reference Figure 3 As an alternative, the first card holder 11 and the second card holder 12 are slidably mounted on the fixed base 1 along a second direction, the second direction being the direction from the first card holder 11 toward the second card holder 12; the lateral drive assembly 3 includes a locking assembly 33, which locks the first card holder 11 or the second card holder 12 in a first position 5.
[0051] Specifically, the first card holder 11 is slidably mounted on the fixed base 1 along the second direction, and the first card holder 11 slides freely on the fixed base 1 within a set area. The second card holder 12 is slidably mounted on the fixed base 1 along the second direction, and the second card holder 12 slides freely on the fixed base 1 within a set area.
[0052] In another embodiment, the first card holder 11 and the second card holder 12 can be moved to or removed from the first position 5 using other existing mechanisms, such as a robotic arm grasping the first card holder 11 or the second card holder 12.
[0053] Locking component 33 moves to the first position 5 and locks the first card holder 11, keeping the first card holder 11 fixed in the first position 5. Locking component 33 moves to the second card holder 12 in the first position 5 and locks it, keeping the second card holder 12 fixed in the first position 5.
[0054] Reference Figure 3 As an optional solution, the locking component 33 includes a spring-loaded latch 331 and two slots 332. The two slots 332 are respectively disposed on the first slot 11 and the second slot 12; the spring-loaded latch 331 is fixed on the fixing base 1 for engaging with the slots 332 on the first slot 11 or the second slot 12 at the first position 5.
[0055] Specifically, the slot 332 is an arc-shaped slot. The fixed base 1 is provided with a clearance space and a connecting hole. The clearance space is provided at one end of the fixed base 1 facing away from the movable base 2. The clearance space does not penetrate the fixed base 1. The connecting hole is provided on the inner wall of the clearance space and penetrates the fixed base 1.
[0056] The spring clip 331 is a U-shaped spring clip with a cylindrical protrusion on one side. The spring clip 331 is set in the clearance space. The cylindrical protrusion of the spring clip 331 is at least partially located in the connecting hole and can extend out of the connecting hole to abut against the side wall or slot 332 of the first card seat 11 or the second card seat 12.
[0057] It should be noted that a stop block is also fixedly connected to the fixed base 1, which encloses the spring clip 331 in the clearance space.
[0058] When the first card holder 11 or the second card holder 12 moves to the first position 5, the card groove 332 corresponds to the cylindrical protrusion on the spring clip 331. When the cylindrical protrusion on the spring clip 331 is inserted into the card groove 332, it restricts the first card holder 11 or the second card holder 12 from moving in the first direction.
[0059] When the first card holder 11 or the second card holder 12 moves along the first direction, the spring-loaded latch 331 is in an elastically deformed state, the cylindrical protrusion of the spring-loaded latch 331 is located in the communicating hole, and the cylindrical protrusion of the spring-loaded latch 331 abuts against the side wall of the first card holder 11 or the second card holder 12.
[0060] When the first card holder 11 moves to the first position 5, the cylindrical protrusion of the spring-loaded latch 331 corresponds to the card slot 332 on the first card holder 11. The cylindrical protrusion of the spring-loaded latch 331 extends out of the connecting hole and is embedded in the card slot 332, preventing the first card holder 11 from sliding in the first direction.
[0061] When it is necessary to move the first card holder 11 out of the first position 5, a large force is applied to the first card holder 11, so that the pressure between the side of the card slot 332 and the cylindrical protrusion is greater than the elastic force of the spring clip 331, further compressing the spring clip 331 until the cylindrical protrusion of the spring clip 331 is pressed into the connecting hole, and the cylindrical protrusion of the spring clip 331 abuts against the side wall of the first card holder 11 or the second card holder 12, and the first card holder 11 can slide along the second direction.
[0062] Furthermore, multiple spring-loaded clips 331 are provided, and multiple slots 332 are arranged in two groups, one group is located in the first slot 11, and the other group is located in the second slot 12. All slots 332 in each group correspond one-to-one with the spring-loaded clips 331. The arrangement of multiple spring-loaded clips 331 helps to keep the first slot 11 or the second slot 12 stably fixed in the first position 5.
[0063] Reference Figure 3 As an optional solution, the lateral drive assembly 3 includes a third drive member 31 and a reset member 32; the first card holder 11 and the second card holder 12 are located between the third drive member 31 and the reset member 32 along the second direction; the third drive member 31 drives the first card holder 11 and the second card holder 12 to slide towards the reset member 32 along the second direction; the reset member 32 drives the first card holder 11 and the second card holder 12 to slide towards the third drive member 31 along the second direction.
[0064] Specifically, the reset member 32, the first card holder 11, the second card holder 12, and the third driving member 31 are arranged sequentially along the second direction. In another embodiment, the reset member 32, the second card holder 12, the first card holder 11, and the third driving member 31 are arranged sequentially along the second direction. The third driving member 31 is a cylinder arranged along the second direction, and the third driving member 31 is fixed on the fixed base 1. The output end of the third driving member 31 abuts against the side wall of the second card holder 21 facing away from the first card holder 1 along the second direction.
[0065] The first card holder 11 and the second card holder 12 are in contact with each other along the opposite sidewalls in the second direction. When the third driving member 31 applies pressure to the second card holder 12 in the second direction toward the reset member 32, the second card holder 12 squeezes the first card holder 11. The second card holder 12 and the first card holder 11 move synchronously in the second direction, which can move the first card holder 11 out of the first position 5 and the second card holder 12 move to the first position 5. It should be noted that at this time, the pressure of the reset member 32 on the first card holder 11 is less than the pressure of the third driving member 31 on the second card holder 12.
[0066] When the reset member 32 applies pressure along the second direction toward the third drive member 31 to the second card holder 12, the second card holder 12 presses against the first card holder 11. The second card holder 12 and the first card holder 11 move synchronously along the second direction, which can move the first card holder 11 out of the first position 5 and move the second card holder 12 to the first position 5. It should be noted that at this time, the pressure of the reset member 32 on the first card holder 11 is greater than the pressure of the third drive member 31 on the second card holder 12.
[0067] This enables the lateral drive component 3 to move the first card holder 11 or the second card holder 12 to or from the first position 5, respectively.
[0068] Reference Figure 3 As an alternative, the reset element 32 includes a compression spring.
[0069] Specifically, the compression spring is arranged along the second direction, with one end of the compression spring pressing against the fixed seat 1 and the other end pressing against the first card seat 11.
[0070] When the third driving member 31 drives the first card holder 11 and the second card holder 12 to move toward the reset member 32 in the second direction, the first card holder 11 squeezes the compression spring, and the compression spring is further compressed; when the output end of the third driving member 31 moves away from the first card holder 11, the compression spring pushes the first card holder 11 and the second card holder 12 to move toward the third driving member 31.
[0071] By using compression springs to apply force to the first card holder 11 and the second card holder 12, excessive pressure can be avoided by the third driving member 31 and the reset member 32 on the first card holder 11 and the second card holder 12, which helps to reduce the failure rate of the device.
[0072] Reference Figure 3 As an optional solution, the fixed base 1 is also provided with a sliding base 13, which is slidably mounted on the fixed base 1 in the second direction; the first card holder 11 and the second card holder 12 are fixed on the sliding base 13.
[0073] Specifically, a guide groove 15 is provided on the lower surface of the fixed base 1. The guide groove 15 extends through both ends of the fixed base 1 along the second direction. The opening of the guide groove 15 is smaller than the inner cavity. For example, the cross-section of the guide groove 15 is "convex". In another embodiment, the cross-section of the guide groove 15 is an inverted trapezoid.
[0074] The cross-section of the sliding seat 13 matches the guide groove 15, and the sliding seat 13 slides in the guide groove 15 along the second direction. The first retaining seat 11 and the second retaining seat 12 are fixed on the sliding seat 13. When the sliding seat 13 slides along the second direction, the first retaining seat 11 and the second retaining seat 12 slide synchronously along the second direction.
[0075] The sliding seat 13, which cooperates with the guide groove 15, enables the sliding connection of the first card holder 11 and the second card holder 12 on the sliding seat 13. The cooperation accuracy between the sliding seat 13 and the guide groove 15 is relatively high, and the sliding contact surface is relatively large, which can improve the stability and accuracy of the first card holder 11 and the second card holder 12 when sliding on the fixed seat 1 along the second direction.
[0076] It should be noted that in this embodiment, both slots 332 are provided on the sliding seat 13, and the two slots 332 are spaced apart along the second direction.
[0077] In another embodiment, a slider located in a guide groove 15 is fixed on the first card holder 11, and the slider slides in the guide groove 15 along a second direction. A slider located in a guide groove 15 is fixed on the second card holder 12, and the slider slides in the guide groove 15 along a second direction.
[0078] Reference Figure 3 As an optional solution, the second card holder 12 includes a base 121 and a fixing ring 122. The base 121 is slidably mounted on the fixing seat 1 along the first direction, and a connecting groove 123 is provided at the end of the base 121 facing away from the fixing seat 1; the fixing ring 122 is located in the connecting groove 123 and is detachably fixed in the connecting groove 123.
[0079] Specifically, in this embodiment, the base 121 is a square block fixed on the sliding seat 13. The end of the base 121 facing away from the fixed seat 1 along the first direction is provided with a connecting groove 123, which is a cylindrical groove.
[0080] The fixing ring 122 is a rubber ring that is bonded and fixed to the base 121. The fixing ring 122 is located in the connecting groove 123, and the inner diameter of the fixing ring 122 is slightly smaller than the outer diameter of the medicine bottle 6 to be placed.
[0081] After inserting the medicine bottle 6 into the retaining ring 122, the medicine bottle 6 is pressed against the retaining ring 122, thereby fixing the medicine bottle 6 onto the retaining ring 122. The medicine bottle 6 is generally made of glass. Using a rubber retaining ring 122 to press and fix the medicine bottle 6 can reduce the risk of breakage. It is also convenient to insert or remove the medicine bottle 6 into the retaining ring 122, making it easier for medical staff to operate.
[0082] Furthermore, the end of the retaining ring 122 facing away from the bottom of the connecting groove 123 is provided with a rounded corner, which facilitates the insertion of the medicine bottle 6 into the retaining ring 122.
[0083] Reference Figure 1 As an optional solution, it also includes a guide rail 14, which is fixedly connected to the fixed base 1, and the movable base 2 is slidably mounted on the guide rail 14.
[0084] Specifically, the guide rail 14 is a long strip track arranged along the first direction. One end of the guide rail 14 is fixed to the fixed base 1, and the other end extends downward along the second direction.
