[0026] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the quantitative drug delivery device in an embodiment of this utility model. Figure 2 This is a cross-sectional view of the quantitative drug delivery device in an embodiment of the present invention. This embodiment provides a quantitative drug delivery device, including a medicine barrel 110 and a medicine cup 150, as well as a drug inlet pipe 120, a drug delivery pump 130, a drug delivery tube 140, and an electronic scale 160. The two ends of the drug inlet pipe 120 are respectively connected to the outlet end of the medicine barrel 110 and the inlet end of the drug delivery pump 130. The outlet end of the drug delivery pump 130 is connected to the inlet end of the drug delivery tube 140. The outlet end of the drug delivery tube 140 is connected to the inlet end of the medicine cup 150. The medicine cup 150 is mounted on the electronic scale 160.

[0027] Since the two ends of the inlet tube 120 are respectively connected to the outlet end of the medicine barrel 110 and the inlet end of the drug delivery pump 130, the outlet end of the drug delivery pump 130 is connected to the inlet end of the drug delivery tube 140, and the outlet end of the drug delivery tube 140 is connected to the inlet end of the medicine cup 150, the liquid medicine in the medicine barrel 110 can be pumped into the medicine cup 150 by the drug delivery pump 130. Since the medicine cup 150 is set on the electronic scale 160, the weight of the liquid medicine in the medicine cup 150 can be measured by the electronic scale 160 to accurately control the dosage of the drug delivery pump 130, thereby improving the accuracy of drug delivery.

[0028] The quantitative drug delivery device also includes a controller that controls the shut-off of the drug delivery pump 130 based on the weight of the drug in the medicine cup 150. Since the medicine cup 150 is mounted on the electronic scale 160, the controller controls the shut-off of the drug delivery pump 130 based on the weight of the drug in the medicine cup 150. Therefore, the drug delivery amount of the drug delivery pump 130 can be accurately controlled by measuring the weight of the drug liquid in the medicine cup 150 through the electronic scale 160, thereby improving the accuracy of drug delivery.

[0029] The quantitative drug delivery device also includes a first buffer pad 180, and the drug delivery pump 130 is disposed on the first buffer pad 180. Therefore, the vibration generated when the drug delivery pump 130 is working will not affect the operation of the electronic scale 160, thereby further improving the drug delivery accuracy of the quantitative drug delivery device.

[0030] The quantitative drug delivery device further includes a drug delivery box 170, with the drug delivery pump 130 partially disposed within the drug delivery box 170, the first buffer pad 180 disposed within the drug delivery box 170, and the electronic scale 160 disposed at the drug delivery box 170. Because the first buffer pad 180 is disposed within the drug delivery box 170, the drug delivery pump 130 is disposed on the first buffer pad 180, and the electronic scale 160 is disposed at the drug delivery box 170, and both the electronic scale 160 and the drug delivery pump 130 are disposed at the drug delivery box 170, the integration of the quantitative drug delivery device can be improved, facilitating its carrying, transportation, and installation.

[0031] Furthermore, a second buffer pad is provided at the contact point between the drug delivery pump 130 and the drug delivery box 170, which can further reduce the impact of the peristaltic pump on the electronic scale 160.

[0032] In this embodiment, the electronic scale 160 is partially disposed inside the drug delivery box 170, and the top of the electronic scale 160 extends outside the drug delivery box 170. This further improves the integration of the quantitative drug delivery device.

[0033] Furthermore, the quantitative drug delivery device also includes a third buffer pad 190 disposed inside the drug delivery box 170, and the electronic scale 160 is disposed on the third buffer pad 190.

[0034] The quantitative drug delivery device also includes a display screen 200 for displaying the amount of medicine in the medicine cup 150.

[0035] Furthermore, the display screen 200 is disposed on the drug delivery box 170.

[0036] The quantitative drug delivery device also includes a control panel for inputting control commands, and the control panel is connected to the controller.

[0037] The bottom of the medicine tank 110 is provided with a water outlet pipe that communicates with the medicine inlet pipe 120. A connector 210 is provided on the water outlet pipe, and the port of the medicine inlet pipe 120 is detachably connected to the connector 210. In this way, when the medicine tank 110 has finished dispensing the medicine, it is easy to connect a new medicine tank 110 to the port of the medicine inlet pipe 120.

[0038] Preferably, a first switch valve is provided at the water outlet pipe.

[0039] Preferably, a second switching valve 220 is provided at the outlet end of the drug delivery tube 140 to prevent the drug liquid in the drug delivery tube 140 from flowing out and being wasted.

[0040] In this embodiment, the drug delivery pump 130 is a peristaltic pump.

[0041] The procedure for using the quantitative drug delivery device is as follows:

[0042] First, connect the port of the drug inlet tube 120 to the drug container 110 and the drug delivery pump 130.

[0043] Next, the drug delivery tube 140 is connected to the drug delivery pump 130 and the medicine cup 150.

[0044] Next, the drug delivery pump 130 is started by controlling the operation panel. When the liquid in the medicine cup 150 reaches the predetermined amount, the controller controls the peristaltic pump to stop working.

[0045] The quantitative drug delivery device in this embodiment greatly improves the efficiency and speed of drug preparation, realizing automatic quantitative dispensing of drug solution during the quantitative dispensing process; it improves work efficiency and speeds up the work progress; and it saves costs and reduces labor costs.

[0046] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
