[0034] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0035] Below, with reference to Figure 1 and Figure 2Describe a reagent injection device 200 and a movable injection cart according to an embodiment of the present utility model. The reagent can be a liquid reagent or a solid reagent. The liquid reagent can be a liquid drug or other chemical liquid reagent, and the solid reagent can be a powdered drug. In this application, the reagent is taken as an example of a drug for illustration. The drug can be a radioactive drug, physiological saline, etc. A radioactive drug refers to a special type of drug containing a radioactive nuclide and used for medical diagnosis and treatment. The radioactive drug can be a drug for tumor diagnosis and treatment.

[0036] As Figure 1 shown, the reagent injection device 200 according to an embodiment of the present utility model includes: a device main body 201, and the device main body 201 is provided with a plurality of driving pumps 23; a reagent conveying device 100, the reagent conveying device 100 includes a confluence pipeline 10 and a plurality of conveying pipelines 20. The plurality of conveying pipelines 20 are all adapted to communicate with corresponding reagent bottles 30. The confluence pipeline 10 is communicated with the plurality of conveying pipelines 20 so that the conveying pipelines 20 communicate the confluence pipeline 10 and the corresponding reagent bottles 30. Each conveying pipeline 20 cooperates with a corresponding driving pump 23 so that the reagent in the corresponding reagent bottle 30 flows into the confluence pipeline 10. The confluence pipeline 10 is adapted to communicate with an indwelling needle.

[0037] Among them, the device main body 201 is provided with a plurality of driving pumps 23. For example: the device main body 201 can be provided with two, three, four or other numbers of driving pumps 23, but the present utility model is not limited thereto. The device main body 201 can also be provided with other numbers of driving pumps 23 as long as the device main body 201 is provided with a plurality of driving pumps 23. The driving pump 23 can be a peristaltic pump, a screw pump or other pump bodies. In this application, the driving pump 23 is taken as an example of a peristaltic pump for illustration. The peristaltic pump has sufficient self-suction force, and the peristaltic pump has good sealing performance and high precision, and can achieve quantitative transmission, so as to improve the accuracy of the reagent conveying device 100 for taking reagents. At the same time, the peristaltic pump is easy to maintain and can reduce the maintenance cost of the reagent injection device 200.

[0038] The reagent delivery device 100 includes a confluence pipeline 10 and a plurality of delivery pipelines 20. For example, the reagent delivery device 100 may include two, three, four, or other numbers of delivery pipelines 20. However, the present utility model is not limited thereto. The reagent delivery device 100 may also include other numbers of delivery pipelines 20 as long as the reagent delivery device 100 includes a plurality of delivery pipelines 20. The plurality of delivery pipelines 20 are all adapted to communicate with corresponding reagent bottles 30. For example, the delivery pipeline 20 and the reagent bottle 30 may be connected by a needle 42 to enable the delivery pipeline 20 to communicate with the reagent bottle 30, so that the reagent in the reagent bottle 30 can enter the corresponding delivery pipeline 20. The ratio of the reagents delivered by the delivery pipeline 20 can be set through a software system according to the infusion plans of different patients, thereby enabling convenient and accurate access to reagents without manual access to reagents, avoiding waste of reagents due to operational errors during manual access to reagents, and when the reagent is toxic or radioactive, using the delivery pipeline 20 to access the reagent can also avoid harm to the health of staff by toxic and radioactive reagents.

[0039] The reagent delivery device 100 of the present application can be used in radioactive drug injection scenarios or can also be used in other mixed reagent scenarios. For example, it can be used in drug mixing scenarios and can communicate with reagent containers to mix drugs. The confluence pipeline 10 and the plurality of delivery pipelines 20 can be integrally formed, or the confluence pipeline 10 and the plurality of delivery pipelines 20 can also be assembled through Luer connectors to enable the confluence pipeline 10 to communicate with the plurality of delivery pipelines 20, so that the delivery pipelines 20 communicate the confluence pipeline 10 and the corresponding reagent bottles 30, thereby enabling the reagents in each reagent bottle 30 to be delivered to the confluence pipeline 10. In the radioactive drug injection scenario, one of the reagent bottles 30 stores radioactive drugs and the other reagent bottle 30 stores normal saline. Before radioactive drug injection, the air in the delivery pipeline 20 is emptied with normal saline. After the drug injection is completed, normal saline is delivered again to push the residual liquid medicine in the confluence pipeline 10 into the patient's body, thereby making the reagent delivery process more stable and healthy, the drug injection volume more accurate, and also avoiding harm to the health of staff by toxic and radioactive reagents. On the other hand, in the reagent (drug) mixing scenario, it can enable the reagents in each reagent bottle 30 to enter the confluence pipeline 10 through the corresponding delivery pipelines 20 for mixing, thereby enabling convenient and accurate mixing of reagents without manual preparation of reagents, realizing automatic drug delivery, and improving the drug preparation efficiency.

[0040] Each delivery pipeline 20 is coordinated with a corresponding drive pump 23 to enable the reagent in the corresponding reagent bottle 30 to flow into the confluence pipeline 10. The dosage of the reagent delivered by the delivery pipeline 20 can be set and controlled by a software system according to the infusion plan of different patients to operate the drive pump 23. Then, the drive pump 23 pumps the reagent in the corresponding reagent bottle 30 into the corresponding delivery pipeline 20. Different reagents in the delivery pipeline 20 flow into the confluence pipeline 10 successively. The confluence pipeline 10 is connected to an indwelling needle. For example: as Figure 2 shown, the confluence pipeline 10 is connected with a connector 15. The connector 15 can be a luer connector. The luer connector is connected to and communicates with the indwelling needle. The indwelling needle is inserted into the patient's body, enabling the reagent in the pipeline to be delivered to the patient's body through the indwelling needle to complete the infusion. The reagent configuration process of the reagent injection device 200 of the present application is accurate, convenient, and efficient. It not only improves the safety of infusion but also can ensure the accuracy of drug dosage injection to the greatest extent, avoid reagent waste, and avoid the harm of toxic and radioactive reagents to the health of staff.

[0041] It can be explained that the reagent bottle 30 can be a container for holding reagents. For example: the reagent bottle 30 can be a bottle or a bag, etc. Further, the reagent bottle 30 can specifically be a vial and a saline bag.

[0042] According to the reagent injection device 200 of the embodiment of the present utility model, by providing a plurality of drive pumps 23 and a reagent delivery device 100, and a plurality of delivery pipelines 20 are all adapted to communicate with the corresponding reagent bottles 30, the confluence pipeline 10 is communicated with a plurality of delivery pipelines 20 so that the delivery pipelines 20 communicate the confluence pipeline 10 and the corresponding reagent bottles 30. Each delivery pipeline 20 is adapted to cooperate with a corresponding drive pump 23 to enable the reagent in the corresponding reagent bottle 30 to flow into the confluence pipeline 10. The confluence pipeline 10 is adapted to communicate with an indwelling needle, and can enable the drug to be delivered to the patient's body through the indwelling needle. Before drug injection, the air bubbles in the pipeline are emptied with normal saline to ensure injection safety; after drug injection, the residual drug in the confluence pipeline 10 is pushed into the patient's body with normal saline, improving the accuracy of drug dosage injection and also avoiding the harm of toxic and radioactive reagents to the health of staff.

[0043] In some embodiments of the present utility model, as Figure 1 shown, the device main body 201 can include a housing 202. The housing 202 can be made of materials such as metal and plastic. For example: the housing 202 can be made of steel plate. The steel plate material has relatively high strength and stiffness, which can enhance the stiffness and strength of the device main body 201, and further can enhance the service life of the reagent injection device 200.

[0044] A plurality of driving pumps 23 can all be fixedly arranged on the side wall of the housing 202. For example, the plurality of driving pumps 23 and the housing 202 can all be fixedly connected by bolts, or the plurality of driving pumps 23 and the housing 202 can all be fixedly connected by snap connection. However, the present invention is not limited thereto, and the plurality of driving pumps 23 and the housing 202 can also be fixedly connected by other means, as long as the plurality of driving pumps 23 are all fixedly arranged on the side wall of the housing 202.

[0045] Thus, the plurality of driving pumps 23 are all fixedly arranged on the side wall of the housing 202, which can enable the plurality of driving pumps 23 to drive the reagents in the corresponding reagent bottles 30 to flow into the corresponding conveying pipelines 20. The sequence or ratio of the reagents conveyed by the conveying pipelines 20 can be set by a software system according to different usage scenarios. Furthermore, it can facilitate and accurately access the reagents without manual access, avoid waste of reagents caused by operation errors during manual access of reagents, and when the reagent is toxic or radioactive, using the driving pump 23 to pump the reagent in the corresponding reagent bottle 30 into the corresponding conveying pipeline 20 can also avoid harm to the health of the staff by the toxic and radioactive reagents.

[0046] As Figure 2 shown, each conveying pipeline 20 can also be provided with a limiting portion 44. When each conveying pipeline 20 is matched with the corresponding driving pump 23, the limiting portion 44 can play a limiting role on the conveying pipeline 20, thereby reducing the risk of the conveying pipeline 20 falling off from the driving pump 23, and further improving the safety and reliability of the reagent conveying device 100.

[0047] In some embodiments of the present invention, as Figure 1 shown, the plurality of driving pumps 23 can be fixedly arranged on the same side wall of the housing 202, which is convenient for the arrangement of the plurality of conveying pipelines 20, and is also beneficial for a single staff member to simultaneously observe the working conditions of the plurality of driving pumps 23 and the plurality of conveying pipelines 20, thereby reducing the waste of working hours and manpower, and further reducing the injection cost of the reagent injection device 200 invisibly.

[0048] In some embodiments of the present invention, as Figure 1 shown, a plurality of fixing seats 203 can be fixedly arranged on the outer surface of the housing 202, and the plurality of fixing seats 203 are respectively used for installing the confluence pipeline 10 and the plurality of conveying pipelines 20.

[0049] Among them, a plurality of fixing seats 203 can be fixedly arranged on the outer surface of the outer shell 202. For example, two, three, four or other numbers of fixing seats 203 can be fixedly arranged on the outer surface of the outer shell 202. However, the present invention is not limited thereto, and other numbers of fixing seats 203 can also be fixedly arranged on the outer surface of the outer shell 202, as long as a plurality of fixing seats 203 are fixedly arranged on the outer surface of the outer shell 202. The plurality of fixing seats 203 are respectively used for installing the converging pipeline 10 and a plurality of conveying pipelines 20. The fixing seat 203 can be formed with a clamping interface. The converging pipeline 10 can be clamped to the clamping interface of the corresponding fixing seat 203, and the conveying pipeline 20 can be clamped to the clamping interface of the corresponding fixing seat 203. The converging pipeline 10 can also be bonded to the corresponding fixing seat 203, and the conveying pipeline 20 can also be bonded to the corresponding fixing seat 203. With such an arrangement, the extending paths of the converging pipeline 10 and the conveying pipeline 20 can be regularized, so as to reduce the risks of the converging pipeline 10 and the conveying pipeline 20 moving around and colliding, and can also reduce the risk of the converging pipeline 10 and the conveying pipeline 20 winding around each other, and can also reduce the risk of the converging pipeline 10 and the conveying pipeline 20 winding around other components on the surface of the outer shell 202, thereby being beneficial to improving the safety and reliability of the converging pipeline 10 and the conveying pipeline 20 for conveying reagents.

[0050] In some embodiments of the present invention, as Figure 1 shown, a plurality of fixing seats 203 are all arranged on the top wall of the outer shell 202, and at least part of the converging pipeline 10 and at least part of each conveying pipeline 20 are located above the outer shell 202.

[0051] Among them, a plurality of fixing seats 203 can all be arranged on the top wall of the outer shell 202. For example, the fixing seat 203 and the outer shell 202 can be fixedly connected by bolts, or the fixing seat 203 and the outer shell 202 can be fixedly connected by bonding. However, the present invention is not limited thereto, and the fixing seat 203 and the outer shell 202 can also be fixedly connected by other means, as long as a plurality of fixing seats 203 are all arranged on the top wall of the outer shell 202. At least part of the converging pipeline 10 and at least part of each conveying pipeline 20 are located above the outer shell 202, so that the plurality of fixing seats 203 can fix the converging pipeline 10 and the conveying pipeline 20 on the top wall of the outer shell 202, so that the converging pipeline 10 and the conveying pipeline 20 are within the controllable range of the staff, which is convenient for the staff to observe and operate, thereby improving the work efficiency of the staff.

[0052] In some embodiments of the present invention, as Figure 1As shown, the manifold pipeline 10 is fitted and assembled with at least one fixing seat 203. For example, the manifold pipeline 10 can be fitted and assembled with one, two, three or other numbers of fixing seats 203, but the present invention is not limited thereto. The manifold pipeline 10 can also be fitted and assembled with other numbers of fixing seats 203, as long as the manifold pipeline 10 is fitted and assembled with at least one fixing seat 203. Each delivery pipeline 20 is fitted and assembled with at least one fixing seat 203. For example, each delivery pipeline 20 can be fitted and assembled with one, two, three or other numbers of fixing seats 203, but the present invention is not limited thereto. Each delivery pipeline 20 can also be fitted and assembled with other numbers of fixing seats 203, as long as each delivery pipeline 20 is fitted and assembled with at least one fixing seat 203.

[0053] With such an arrangement, the risk of the manifold pipeline 10 and the delivery pipelines 20 moving around and colliding can be further reduced, the risk of the manifold pipeline 10 and the delivery pipelines 20 winding around each other can be further reduced, and the risk of the manifold pipeline 10 and the delivery pipelines 20 winding around other components on the surface of the housing 202 can be further reduced. Furthermore, it is more conducive to improving the safety and reliability of the manifold pipeline 10 and the delivery pipelines 20 for delivering reagents.

[0054] In some embodiments of the present invention, as Figure 1 shown, the reagent delivery device 100 may further include: a manifold block 13. A manifold cavity 14 is formed in the manifold block 13. The manifold block 13 is connected to both the manifold pipeline 10 and a plurality of delivery pipelines 20. The manifold cavity 14 is in communication with both the manifold pipeline 10 and the plurality of delivery pipelines 20. The manifold block 13 is fixedly provided on the equipment main body 201.

[0055] Among them, the reagent delivery device 100 may be provided with a manifold block 13. The manifold block 13 may be fixedly provided on the equipment main body 201. For example, the manifold block 13 and the equipment main body 201 may be fixedly connected by snap connection, or the manifold block 13 and the equipment main body 201 may be fixedly connected by bonding. However, the present invention is not limited thereto. The manifold block 13 and the equipment main body 201 may also be fixedly connected by other means, as long as the manifold block 13 is fixedly provided on the equipment main body 201. The manifold block 13 is connected to both the manifold pipeline 10 and the plurality of delivery pipelines 20, so that the plurality of delivery pipelines 20 and the manifold pipeline 10 can converge at the manifold block 13. A manifold cavity 14 may be formed in the manifold block 13, and the manifold cavity 14 is in communication with both the manifold pipeline 10 and the plurality of delivery pipelines 20. Thus, in the drug injection use scenario, the reagents in the plurality of delivery pipelines 20 can flow into the manifold cavity 14 successively, thereby ensuring the safety and accuracy of the injection. In addition, in the reagent (drug) mixing use scenario, the reagents in the plurality of delivery pipelines 20 can also flow into the manifold cavity 14 for mixing and then flow into the manifold pipeline 10, thereby achieving the effect of reagent mixing.

[0056] In some embodiments of the present utility model, such as Figure 1 shown, at least one of the confluence pipeline 10 and multiple conveying pipelines 20 is provided with a bubble detection member 41, and the bubble detection member 41 is fixedly arranged on the equipment main body 201.

[0057] Among them, at least one of the confluence pipeline 10 and multiple conveying pipelines 20 is provided with a bubble detection member 41. For example, the confluence pipeline 10 can be provided with a bubble detection member 41, or a conveying pipeline 20 can be provided with a bubble detection member 41. However, the present utility model is not limited thereto. Both the confluence pipeline 10 and a conveying pipeline 20 can also be provided with a bubble detection member 41, as long as at least one of the confluence pipeline 10 and multiple conveying pipelines 20 is provided with a bubble detection member 41. As an embodiment of the present utility model, both the confluence pipeline 10 and multiple conveying pipelines 20 are provided with a bubble detection member 41, and the bubble detection member 41 can be a bubble sensor. With such a setting, it is possible to detect whether there are bubbles in both the confluence pipeline 10 and multiple conveying pipelines 20, so that the staff can timely remove the bubbles, thereby effectively avoiding the bubbles from entering the patient's body, which is beneficial to ensuring the safety of the patient.

[0058] The bubble detection member 41 can be fixedly arranged on the equipment main body 201. For example, the connection between the bubble detection member 41 and the equipment main body 201 can be a snap connection, or the connection between the bubble detection member 41 and the equipment main body 201 can be an adhesive connection. However, the present utility model is not limited thereto. The connection between the bubble detection member 41 and the equipment main body 201 can also be in other ways, as long as the bubble detection member 41 is fixedly arranged on the equipment main body 201. Thus, the bubble detection member 41 is fixedly arranged on the equipment main body 201, which can reduce the risk of the bubble detection member 41 moving around, so as to avoid the bubble detection member 41 moving around randomly and affecting the detection effect, and further improve the safety and reliability of the bubble detection member 41.

[0059] In some embodiments of the present utility model, such as Figure 1As shown, the confluence pipeline 10 may be provided with a flow detection member 40, which can detect the drug input volume of the patient, accurately record the real-time measurement data, facilitate subsequent diagnosis, and the cooperation of the flow detection member 40 and the above-mentioned bubble detection member 41 can further improve the pipeline safety of the reagent delivery device 100, and thus can further facilitate the protection of the patient's safety. The flow detection member 40 is fixedly arranged on the equipment main body 201. For example, the connection between the flow detection member 40 and the equipment main body 201 can be a snap connection, or the connection between the flow detection member 40 and the equipment main body 201 can be an adhesive connection. However, the present invention is not limited thereto, and the connection between the flow detection member 40 and the equipment main body 201 can also be in other ways, as long as the flow detection member 40 is fixedly arranged on the equipment main body 201. Thus, the flow detection member 40 is fixedly arranged on the equipment main body 201, which can reduce the risk of the flow detection member 40 moving around, so as to avoid the influence on the detection effect caused by the random movement of the flow detection member 40, and further improve the safety and reliability of the flow detection member 40.

[0060] In some embodiments of the present invention, as Figure 1 shown, the equipment main body 201 may be provided with a mounting bracket 204. For example, the connection between the mounting bracket 204 and the equipment main body 201 can be fixedly connected by bolts, or the connection between the mounting bracket 204 and the equipment main body 201 can be fixedly connected by snap connection. However, the present invention is not limited thereto, and the connection between the mounting bracket 204 and the equipment main body 201 can also be in other ways, as long as the equipment main body 201 is provided with the mounting bracket 204. The flow detection member 40 can be fixedly arranged on the mounting bracket 204. The connection between the flow detection member 40 and the mounting bracket 204 can be by bolt connection, or the connection between the flow detection member 40 and the mounting bracket 204 can be by snap connection. However, the present invention is not limited thereto, and the connection between the flow detection member 40 and the mounting bracket 204 can also be in other ways, as long as the flow detection member 40 is fixedly arranged on the mounting bracket 204. Thus, the flow detection member 40 can be stably mounted on the equipment main body 201, thereby further effectively reducing the risks of the flow detection member 40 shaking and moving around, and further improving the safety and reliability of the flow detection member 40.

[0061] In some embodiments of the present invention, as Figure 1 shown, the confluence pipeline 10 may be provided with an air filter 43, which can filter microorganisms, particulate matters, and bubbles in the liquid medicine during the infusion process, thereby avoiding symptoms such as patient infection and allergy, and further effectively protecting the safety of the patient, and also improving the safety and reliability of the reagent injection device 200.

[0062] The air filter 43 is fixedly provided on the device main body 201. For example, the air filter 43 and the device main body 201 can be connected by snap connection, or the air filter 43 and the device main body 201 can be connected by adhesive connection. However, the present utility model is not limited thereto. The air filter 43 and the device main body 201 can also be connected in other ways, as long as the air filter 43 is fixedly provided on the device main body 201. Thus, the air filter 43 being fixedly provided on the device main body 201 can reduce the risk of the air filter 43 moving around, so as to avoid the air filter 43 moving around randomly and affecting the detection effect, and further improve the safety and reliability of the air filter 43.

However, the present utility model is not limited thereto. Both the manifold pipe 10 and the plurality of delivery pipes 20 can also be configured as flexible pipes, as long as at least one of the manifold pipe 10 and the plurality of delivery pipes 20 is configured as a flexible pipe. As an embodiment of the present utility model, both the manifold pipe 10 and the plurality of delivery pipes 20 can be configured as flexible pipes. The flexible pipe is made of a non-toxic material, which can ensure that no harm is caused to the patient during the infusion process. The flexible pipe material has a certain elasticity, can adapt to the pressure changes during the infusion process, and can withstand the flow pressure of the infusion liquid. The flexible pipe has flexibility, can pass through curves and bends, which is convenient for the operation and adjustment during the infusion process, and is also convenient for the connection between the delivery pipe 20 and the reagent bottle 30 and the connection between the manifold pipe 10 and the indwelling needle, so as to deliver the reagent into the patient's body. Thus, configuring both the manifold pipe 10 and the plurality of delivery pipes 20 as flexible pipes can effectively ensure the safety and reliability of the infusion process, and further is beneficial to ensuring the safety of the patient.

[0064] In some embodiments of the present utility model, the reagent injection device 200 may further include: a plugging device 304. The plugging device 304 is used to place the corresponding reagent bottle 30, and the plugging device 304 cooperates with the reagent delivery device 100 to drive the reagent delivery device 100 to insert into or pull out of the corresponding reagent bottle 30.

[0065] Among them, the plugging device 304 may have a moving part 305 and a placement groove 306. The moving part 305 and the placement groove 306 are opposite and spaced apart. The placement groove 306 can be used to place the corresponding reagent bottle 30. The reagent delivery device 100 is detachably assembled to the moving part 305, and moves toward or away from the placement groove 306 through the moving part 305 to drive the reagent delivery device 100 to insert into or pull out of the corresponding reagent bottle 30. After the plugging device 304 cooperates with the reagent delivery device 100 to drive the reagent delivery device 100 to insert into the corresponding reagent bottle 30, the reagent delivery device 100 can take the reagent in the corresponding reagent bottle 30. When the reagent in the corresponding reagent bottle 30 is exhausted or the reagent delivery device 100 needs to be replaced, the plugging device 304 and the reagent delivery device 100 cooperate to drive the reagent delivery device 100 to pull out of the corresponding reagent bottle 30, so that the reagent bottle 30 and the reagent delivery device 100 can be replaced, and manual plugging and unplugging of the reagent delivery device 100 can be avoided, thereby reducing the manual labor intensity.

[0066] In some embodiments of the present invention, as Figure 1 shown, the delivery pipelines 20 all have insertion needles 42, and the insertion needles 42 are adapted to be inserted into or pulled out of the corresponding reagent bottles 30.

[0067] Among them, the delivery pipelines 20 can all have insertion needles 42, and the insertion needles 42 are adapted to be inserted into or pulled out of the corresponding reagent bottles 30. When it is necessary to take the reagent, the insertion needles 42 are inserted into the corresponding reagent bottles 30 so that the reagent in the reagent bottles 30 can enter the delivery pipelines 20. The ratio of the reagents delivered by the delivery pipelines 20 can be set through a software system according to the infusion plans of different patients. After the reagent is taken, the insertion needles 42 are pulled out of the corresponding reagent bottles 30. Thus, the reagent can be taken conveniently and accurately without manual taking of the reagent, and the waste of the reagent caused by operation errors during manual taking of the reagent can be avoided. Moreover, when the reagent is toxic or radioactive, using the delivery pipelines 20 to take the reagent can also avoid the harm of the toxic and radioactive reagents to the health of the staff.

[0068] It can be explained that all the pipelines and insertion needles 42 in the reagent injection device 200 of the present application are disposable consumables, which can effectively ensure the safety of patients.

[0069] In some embodiments of the present invention, as Figure 1As shown, there can be two delivery pipelines 20. The two delivery pipelines 20 are respectively connected to two reagent bottles 30 to take two different reagents. The two different reagents can be physiological saline and radioactive drugs. Then, the reagents in the two delivery pipelines 20 flow through the confluence chamber 14 successively to perform safe and accurate injection on the patient, reducing drug waste. And when the reagent is toxic or radioactive, using the confluence pipeline 10 to configure the reagent can also avoid toxic and radioactive reagents from harming the health of the staff. It should be noted that the reagent delivery device 100 can also have other numbers of delivery pipelines 20, which can be reasonably set according to the actual situation.

[0070] As an embodiment of the present application, there can be two delivery pipelines 20. One delivery pipeline 20 delivers radioactive drugs, and the other delivery pipeline 20 delivers physiological saline. First, physiological saline can be delivered through the corresponding delivery pipeline 20 to empty the air and bubbles in the confluence pipeline 10. Then, radioactive drugs are delivered into the patient's body through the corresponding delivery pipeline 20. After the delivery of radioactive drugs is completed, physiological saline is delivered in the direction of the patient's body again through the corresponding delivery pipeline 20, which can wash the radioactive drugs in the confluence pipeline 10 so that the remaining radioactive drugs in the confluence pipeline 10 are delivered into the patient's body. Immediately stop the injection after the remaining radioactive drugs are delivered into the patient's body. In this way, it can ensure the accuracy of drug injection dosage and drug activity to the greatest extent, thus improving the injection accuracy of the reagent injection device 200.

[0071] The movable injection cart according to the embodiment of the present utility model includes the reagent injection device 200 in the above embodiment. By exhausting air bubbles before injection with physiological saline and pushing all the reagents into the human body after injection, the reagent delivery process can be made more stable, accurate, convenient and efficient, reducing waste. In addition, the cumbersome steps of manually configuring reagents can also be omitted, realizing automatic mixing of reagents.
