In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Combine the following Figure 1 to Figure 2 , the drug liquid detection device 100 provided in the embodiment of the present application is described in detail through a specific example.

[0032] Please also read Figure 1 to Figure 2 , Figure 1 It is a structural schematic diagram of the drug liquid detection device provided by the utility model; Figure 2 It is a cross-sectional view of the first mounting seat of the drug liquid detection device provided by the utility model. . The drug liquid detection device 100 provided by one embodiment of the utility model includes a first mounting seat 10, a fixing member 20, a second mounting seat 30 and a detection member 40. The fixing member 20 is telescopically arranged on the first mounting seat 10; the detection member 40 is located on the second mounting seat 30, and the fixing member 20 and the detection member 40 are arranged opposite to each other; wherein, there is a gap between the fixing member 20 and the detection member 40, and the infusion tube 70 is located in the gap, the fixing member 20 and the detection member 40 are jointly in contact with the infusion tube 70, and the detection member 40 can detect the flow rate of the drug liquid flowing in the infusion tube 70.

[0033] In this embodiment, the infusion tube 70 is located in the gap between the fixing member 20 and the detection member 40, and the fixing member 20 and the detection member 40 abut against the infusion tube 70. At this time, the flow rate of the liquid medicine in the infusion tube 70 can be detected by the detection member 40 while the infusion tube 70 is fixed. When the infusion tube 70 is delivering liquid medicine, the detection member 40 in contact with the infusion tube 70 can detect the flow rate of the liquid medicine in the infusion tube 70, so as to know whether the flow rate of the liquid medicine is the same as the set delivery liquid medicine flow rate, thereby ensuring the accuracy of the dosage of the filled liquid medicine.

[0034] The detection member 40 may be a sensor for detecting the flow rate of the liquid, such as a flow meter, a pressure sensor, an optical sensor, etc., which can convert the information of the flow rate of the liquid medicine into a readable value for use by the control system. The detection member 40 is closely matched with the fixing member 20 to ensure that the flow rate of the liquid medicine is accurately detected without interfering with the flow of the liquid medicine.

[0035] In some embodiments, a mounting groove is provided on the second mounting seat 30, and the detection member 40 is located in the mounting groove. By arranging the detection member 40 in the mounting groove, a stable support can be provided to ensure that the detection member 40 will not move unnecessarily due to the flow of the liquid medicine when detecting the flow rate of the liquid medicine, thereby improving the accuracy of the detection. In addition, a mounting groove is provided on the second mounting seat 30 and the detection member 40 is arranged in the mounting groove. At this time, the detection member 40 can contact the infusion tube 70 without squeezing the infusion tube 70, thereby not affecting the infusion tube 70 in conveying the liquid medicine.

[0036] In some embodiments, the fixing member 20 includes a connecting rod 21, a contact head 22 and a first elastic member 23; the connecting rod 21 is located in the first mounting seat 10; the first elastic member 23 is passed through the connecting rod 21; the contact head 22 is located at the end of the connecting rod 21, one end of the first elastic member 23 abuts against the first mounting seat 10, and the other end abuts against the contact head 22.

[0037] The arrangement of the abutment head 22 can ensure stable contact between the fixing member 20 and the infusion tube 70. One end of the first elastic member 23 abuts against the first mounting seat 10, and the other end abuts against the abutment head 22, so that the abutment head 22 can be retracted and reset.

[0038] Through the combination of the connecting rod 21 and the first elastic member 23, the contact head 22 can be flexibly adjusted to better adapt to the infusion tubes 70 of different diameters and ensure the accuracy of the detection. When the infusion tube 70 is thicker, the contact head 22 is subjected to the resisting force, and the first elastic member 23 can be retracted. At this time, the gap between the contact head 22 and the detection member 40 is increased to allow the infusion tube 70 to pass through; when the infusion tube 70 is thinner, the first elastic member 23 can be reset, so that the contact head 22 is close to the detection member 40, and the gap between the contact head 22 and the detection member 40 becomes smaller to contact and fix the infusion tube 70.

[0039] In some embodiments, the first mounting seat 10 defines a groove 11 , and one end of the first elastic member 23 abuts against a groove wall of the groove 11 .

[0040] Specifically, part of the first elastic member 23 is located in the groove 11 and abuts against the bottom wall of the groove 11, and the other part of the elastic member is exposed outside the groove 11 and abuts against the abutment member. Through such an arrangement, both ends of the first elastic member 23 abut against each other, so that when the first elastic member 23 is subjected to force, it can be expanded and contracted to drive the abutment head 22 to flexibly adjust its position.

[0041] Furthermore, by disposing the first elastic member 23 in the groove 11 , the side wall 112 of the groove 11 can limit the first elastic member 23 , thereby preventing the first elastic member 23 from being displaced during the extension and retraction process.

[0042] In some embodiments, a reset assembly 50 is disposed in the first mounting seat 10, and the reset assembly 50 includes a reset plate 51 and a second elastic member 52; one end of the second elastic member 52 abuts against the inner wall 111 of the first mounting seat 10, and the other end abuts against the reset plate 51; the reset plate 51 is set toward the connecting rod 21.

[0043] The reset plate 51 is arranged opposite to the connecting rod 21. When the abutment head 22 retracts, the connecting rod 21 can move toward the reset plate 51 in the first mounting seat 10 and abut against the reset plate 51. At this time, the reset plate 51 can move backward after receiving the force from the connecting rod 21, and the second elastic member 52 abuts against the reset plate 51, and the second elastic member 52 contracts. After the infusion tube 70 is removed, the abutment head 22 is no longer subjected to the abutment force from the infusion tube 70, and the second elastic member 52 relaxes, thereby driving the reset plate 51 to move back to the initial position. At this time, the reset plate 51 can push the connecting rod 21 to move, driving the connecting rod 21 back to the initial position.

[0044] Wherein, both the first elastic member 23 and the second elastic member 52 can be springs.

[0045] In some embodiments, the reset plate 51 is spaced apart from the connecting rod 21. The reset plate 51 and the connecting rod 21 are spaced apart so that there is a certain buffer area between the reset plate 51 and the connecting rod 21, thereby preventing the reset plate 51 from exerting too much abutment force on the connecting rod 21, thereby causing the abutment head 22 to squeeze the infusion tube 70, thereby affecting the normal delivery of the drug solution by the infusion tube 70.

[0046] In some embodiments, the first mounting seat 10 further includes a connector 60, which is disposed at one end of the first mounting seat 10 away from the first mounting seat 10, and the connector 60 is used to connect with a peripheral component. The first mounting seat 10 can be mounted on a peripheral component (such as a contrast agent filling machine) through the connector 60 to prevent the first mounting seat 10 from falling.
