[0019] The present disclosure is described below through several specific embodiments. In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits the detailed description of known functions and known components. Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a drug delivery device for multi-item detection, comprising: The sample placement turntable 3 is provided with a plurality of placement slots 2, and the placement slots 2 are used to place sample bottles 1. The sample placement turntable 3 is driven by a rotating motor 11 to drive the sample bottles 1 to rotate and move. The sample bottles 1 have detection item labels 7 matching the samples.

[0020] The medicine storage unit is arranged above the sample placement turntable 3 and includes a plurality of medicine storage tanks 4. The plurality of medicine storage tanks 4 are used to store medicines for different detection items respectively.

[0021] A plurality of peristaltic pumps 5 are correspondingly arranged below each of the medicine storage tanks 4 . The peristaltic pump 5 is connected to the medicine storage tank 4 via one end of a hose 8 , and the other end of the hose 8 is suspended below the peristaltic pump 5 .

[0022] The plurality of placement slots 2 and the plurality of medicine storage tanks 4 are arranged in a circular array, and the radius of the circular arrays of the two are matched. The arrangement of the circular array can complete the task of testing the placement of multiple medicines of multiple samples only by rotating the motor 11, which reduces the structural complexity of the device, reduces the volume of the device of the embodiment of the present invention, and is easy to carry.

[0023] The scanner 10 is fixedly disposed on one side of the sample placement turntable 3 and is configured to scan the detection item identification 7 on the sample bottle 1. The scanner 10 is, for example, a barcode scanner or other device.

[0024] The controller 9 is electrically connected to the scanner 10, the rotating motor 11 and the peristaltic pump 5. The controller 9 is configured to obtain the detection item information and the drug storage information, transfer the sample bottle 1 to the bottom of the drug storage tank 4 corresponding to the detection item based on the detection item information, the drug storage information and the identification, and control the corresponding peristaltic pump 5 to work to release a set amount of medicine.

[0025] It should be understood that medicine refers to the reagent added to the detection target. For example, in water quality detection projects, medicine refers to the fixed agent added.

[0026] The rotating motor 11 may be, for example, a stepping motor, a servo motor, a brushless DC motor, an AC synchronous motor, or a harmonic reduction motor, etc., which are motors capable of achieving precise rotation angle control.

[0027] In some embodiments, the test project information includes at least the type of sample to be tested, the order and amount of drugs to be administered; The drug storage information includes the correspondence between the drugs and the drug storage tanks 4 .

[0028] In some embodiments, the transferring of the sample bottle 1 to the bottom of the drug storage tank 4 corresponding to the test item based on the test item information, the drug storage information and the identification includes: Acquire the detection item identification 7 corresponding to the sample bottle 1 through the scanner 10; Determine the corresponding test item based on the test item identifier 7, determine the next drug to be put in based on the test item information, and determine the location of the drug storage tank 4 corresponding to the next drug to be put in based on the drug storage information; The motor rotation angle is calculated based on the current position of the sample bottle 1 and the position of the corresponding medicine storage tank 4 , and a control signal is sent to the rotating motor 11 to drive the sample bottle 1 to move to below the corresponding medicine storage tank 4 .

[0029] In some embodiments, an electric lifting mechanism 15 is further included, and the electric lifting mechanism 15 is used to drive the medicine storage unit to perform lifting movement and is electrically connected to the controller 9; The electric lifting mechanism 15 is configured to drive the drug storage unit to descend when the sample bottle 1 moves to the bottom of the corresponding drug storage tank 4 so that the end of the hose 8 extends into the mouth of the sample bottle 1; When the peristaltic pump 5 stops working after the medicine delivery is completed, the medicine storage unit is driven to rise so that the end of the hose 8 is higher than the mouth of the sample bottle 1 .

[0030] Through the cooperation of the electric lifting mechanism 15, on the one hand, it can be avoided that the hose 8 falls outside the sample bottle 1 during the rotation of the turntable due to the end being too low, resulting in the inability to put the medicine in; on the other hand, it can be avoided that the hose 8 is too high, resulting in the end of the hose 8 being unstable due to fluid reasons, causing the medicine to splash and contaminate other samples.

[0031] In some embodiments, the control process of the controller 9 further includes: Based on the dosage of the corresponding medicine in the detection item information, the peristaltic pump 5 is driven to release the corresponding dosage of the medicine.

[0032] Preferably, after the medicine is delivered, the controller 9 determines whether there are other medicines to be delivered for the project. If yes, the above steps are repeated until the delivery is completed. If not, the scanner 10 scans the detection item mark 7 on the next sample bottle 1.

[0033] In some embodiments, the step of driving the peristaltic pump 5 to release a corresponding dose of medicine includes: Calculate the required working time of the peristaltic pump 5 based on the drug delivery amount in the detection item information and the rated flow rate of the peristaltic pump 5; The peristaltic pump 5 is driven to start and stop at a fixed time based on the working time.

[0034] In some embodiments, it also includes an operation interaction interface 13 and a memory 14 both electrically connected to the controller 9; The memory 14 is used to store the test item information and drug storage information; The operation interaction interface 13 is used to input the detection item information and the drug storage information.

[0035] Specifically, in some embodiments, the operator writes the test item information into the memory 14 in advance according to the task requirements. Various drugs can also be added to the drug storage unit. Each time a drug is added, the number or location code of the drug storage tank 4 to which the drug is added can be input through the operation interactive interface 13, and the drug type can be input at the same time.

[0036] Preferably, in some embodiments, the device further comprises a device housing and a handrail, wherein the device housing is used to protect the device, and the handrail is used to push and pull the device. A movable caster can also be installed at the bottom of the device housing to facilitate the movement of the device.

[0037] In some embodiments, a printer 12 is further included, and the detection item identification 7 is a barcode output by the controller 9 through the printer 12 based on the detection item information. Preferably, the barcode may also include a sample sequence number, a sampler identity code, and a sampling date code.

[0038] Specifically, each time the operator uses the sample bottle 1 to collect samples, he first selects the test item corresponding to the sample through the operation interactive interface 13, and then prints the corresponding barcode through the printer 12. After each sampling, the barcode is affixed before placing the sample bottle 1 on the turntable. In this way, the operator does not need to comply with special regulations for the placement of the sample, which reduces the probability of human error.

[0039] In some embodiments, a check valve 6 is further included, and the check valve 6 is arranged on the hose 8, and the check valve 6 is located below the peristaltic pump 5. Preferably, the check valve 6 is a lifting check valve.

[0040] In general, the embodiment of the present invention places multiple sample bottles in a circular array on a sample placement turntable, and a drug storage tank storing different drugs is arranged on the top. The coordination of a peristaltic pump and a turntable rotating motor can improve the efficiency and accuracy of drug delivery for multiple monitoring items. Through the embodiment of the present invention, the operator only needs to complete the sampling operation of each professional sample, and other work is completed by the delivery device provided by the embodiment of the present invention, which greatly improves work efficiency and accuracy.
