[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] like Figures 1 to 4 As shown:

[0025] Example 1: This utility model provides a splash-proof chemotherapy drug dispensing device, including: a collection mechanism 1 and a drug storage mechanism 2;

[0026] The collection mechanism 1 includes a support component 11, a collection component 12 slidably embedded in the support component 11, and a drive component 13 for driving the collection component 12 to move;

[0027] The drug storage mechanism 2 includes a connecting component 21 that is slidably engaged on the support component 11, a plurality of drug storage components 22 that are engaged on the connecting component 21, and an adjusting component 23 for driving the connecting component 21 to rise and fall.

[0028] The support assembly 11 includes an L-shaped support plate 111, on which a set of limiting grooves 112 are provided;

[0029] The connecting component 21 includes a lifting plate 211, on which a plurality of card seats 212 are fixedly connected. On the side of the lifting plate 211 away from the card seats 212, a set of sliders 213 are fixedly connected. The set of sliders 213 and a set of limiting slide grooves 112 are matched. The lifting plate 211 is slidably embedded in the L-shaped support plate 111 through the set of sliders 213. A rack 214 is also fixedly connected on the lifting plate 211 and located between the set of sliders 213.

[0030] The adjustment component 23 includes a drive component 231 fixedly connected to the L-shaped support plate 111. The output end of the drive component 231 is fixedly connected to a gear 232, which meshes with a rack 214.

[0031] The start-up drive unit 231 drives the gear 232 to start rotating. The meshing design of the gear 232 and the rack 214 ensures that the lifting plate 211 can rise or fall smoothly along the L-shaped support plate 111 under the precise guidance of the slider 213, allowing the user to easily adjust the relative distance between the medicine storage component 22 and the collection component 12.

[0032] Specifically, a set of guide rods 113 are fixedly connected to the L-shaped support plate 111, and the driving component 231 includes, but is not limited to, a motor.

[0033] Specifically, several drug storage components 22 include a drug storage tank 221, the top of which is threaded with a sealing cap 222, and a limiting ring 223 is fixedly connected to the outside of the drug storage tank 221. The drug storage tank 221 is locked into the card seat 212 by the limiting ring 223, and a solenoid valve 224 is installed on the drug outlet of the drug storage tank 221.

[0034] Specifically, the collection component 12 includes a support 121 slidably connected to the outside of a set of guide rods 113, and a collection container 122 is fitted onto the support 121.

[0035] As can be seen from the above, in use, multiple drug storage tanks 221 are first inserted one by one into the corresponding slots 212 on the lifting plate 211. Then, by opening the sealing cap 222 on the top of the drug storage tank 221, the required chemotherapy drugs are safely injected into the drug storage tank. Once the drugs are loaded, the drive unit 231 is activated, and its output end drives the gear 232 to start rotating. The meshing design of the gear 232 and the rack 214 ensures that the lifting plate 211 can rise or fall smoothly along the L-shaped support plate 111 under the precise guidance of the slider 213. This allows the user to easily adjust the relative distance between the drug storage component 22 and the collection component 12 to accommodate different drug combinations. To meet the needs of drug preparation, once the drug storage component 22 is adjusted to the appropriate position, the solenoid valve 224 is opened, allowing the drug in the storage tank 221 to flow precisely into the collection tank 122 below. During this process, the flow rate and velocity of the drug can be precisely controlled by the solenoid valve, thereby ensuring the accuracy and stability of drug preparation. By controlling the drive component 13, the user can easily drive the support base 121 and the collection tank 122 on it to move below the next drug storage tank 221 to be prepared, enabling continuous and efficient drug collection and preparation. This not only greatly improves the efficiency of chemotherapy drug preparation but also effectively reduces the risk of drug waste and splashing caused by improper manual operation.

[0036] like Figure 3 and Figure 4 As shown:

[0037] Example 2: This example is basically the same as the previous example, except that the drive assembly 13 includes a motor 131 fixedly connected to the L-shaped support plate 111, and one end of a ball screw 132 is fixedly connected to the output end of the motor 131. The other end of the ball screw 132 is fixedly connected to the L-shaped support plate 111 through a bearing.

[0038] Specifically, the support seat 121 is threaded onto the outside of the ball screw 132.

[0039] As can be seen from the above, after the motor 131 is started, its output end will drive the ball screw 132 to start rotating. Under the precise transmission of the ball screw 132, the support base 121 slides stably along the guide rod 113, ensuring the smoothness and accuracy of the movement. This allows the collection tank 122 installed on the support base 121 to move precisely to the bottom of the designated drug storage component 22, and can easily realize the rapid switching of the collection tank 122 between different drug storage components 22, thereby greatly improving the efficiency of chemotherapy drug preparation.

[0040] Application process:

[0041] Preparation phase:

[0042] Multiple drug storage tanks 221 are inserted one by one into the corresponding slots 212 on the lifting plate 211. The sealing cap 222 on the top of the drug storage tank 221 is opened, the required chemotherapy drugs are injected into the drug storage tank, and then the sealing cap 222 is tightened.

[0043] Adjust height:

[0044] When the drive unit 231 is activated, the output end of the drive gear 232 begins to rotate. The meshing design of the gear 232 and the rack 214 ensures that the lifting plate 211 rises or falls smoothly along the L-shaped support plate 111 under the precise guidance of the slider 213. The relative distance between the drug storage component 22 and the collection component 12 can be adjusted as needed.

[0045] Medication preparation stage:

[0046] Once the drug storage assembly 22 is adjusted to the appropriate position, the solenoid valve 224 is opened, and the drug in the drug storage tank 221 flows precisely into the collection tank 122 below. The flow rate and speed of the drug are controlled by the solenoid valve 224 to ensure the accuracy and stability of the drug dispensing.

[0047] Mobile collection container:

[0048] The motor 131 is started, and its output drives the ball screw 132 to rotate. The support base 121 slides stably along the guide rod 113, realizing the rapid switching of the collection tank 122 between different medicine storage components 22.

[0049] Continuous preparation:

[0050] Repeat the above steps to carry out continuous and efficient drug collection and preparation work until all drugs in storage tanks 221 have been transferred to collection tank 122.

[0051] End of work:

[0052] Turn off drive unit 231 and solenoid valve 224, disconnect the power supply, clean the work area, and prepare for the next use.
