For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] The present application embodiment provides a device for synchronously detecting leakage of an infusion bottle bottom and an infusion bottle leakage detection device. Figures 1 to 5 , the infusion bottle bottom leakage synchronous detection device and the infusion bottle leakage detection equipment provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0031] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a synchronous detection device for bottom leakage of an infusion bottle and an infusion bottle leakage detection device. The disclosed synchronous detection device for bottom leakage of an infusion bottle (hereinafter referred to as the synchronous detection device) includes a mounting plate 100, a first electrode 200, a bottle supporting assembly 300, a pushing member (not shown in the figure), a transmission unit 500, a clamp 600 and a second electrode 700, wherein the first electrode 200 is connected to the mounting plate 100 through the bottle supporting assembly 300. Specifically, the first electrode 200 is a disc-shaped structure, and the first electrode 200 has a accommodating space 210 and an opening connected to the accommodating space 210. Multiple first electrodes 200 are distributed along the circumference of the mounting plate 100, and the opening direction of the first electrode 200 is radially outward. The bottom part of the infusion bottle 800 can be accommodated in the accommodating space 210 through the opening and establish electrical contact with the first electrode 200. Exemplarily, the first electrode 200 can be a negative electrode.

[0032] In the embodiment of the present application, the transmission unit 500 has a portion surrounding the mounting plate 100. For example, the transmission unit 500 can be a chain transmission mechanism, and the transmission unit 500 specifically includes a chain 510, a first sprocket 520 and a second sprocket 530, wherein the chain 510 is wound around the first sprocket 520 and the second sprocket 530, and the aforementioned mounting plate 100 can be coaxially fixedly arranged with one of the first sprocket 520 and the second sprocket 530, and can rotate with the first sprocket 520 or the second sprocket 530. For example, see Figure 1 and Figure 2 , the first sprocket 520 may be a driving sprocket, the second sprocket 530 may be a driven sprocket, the mounting plate 100 is connected and fixed with the second sprocket 530, and when the first sprocket 520 and the second sprocket 530 rotate, the mounting plate 100 can be driven to rotate. In the embodiment of the present application, the clamp 600 is arranged on the transmission unit 500, specifically, the clamp 600 may be fixedly arranged on the chain 510, and when the first sprocket 520 and the second sprocket 530 rotate, the clamp 600 follows the chain 510 and has a running track that rotates around the mounting plate 100. Exemplarily, the clamp 600 may be a spring clamp or an electric clamp, and this embodiment does not specifically limit this, the clamp 600 is used to clamp the infusion bottle 800, and when the transmission unit 500 drives the second sprocket 530 to rotate, the transmission unit 500 can drive the infusion bottle 800 to rotate synchronously relative to the mounting plate 100.

[0033] The transmission unit 500 of the embodiment of the present application adopts a chain transmission mechanism, which can flip the infusion bottle 800 during the detection process. This method can increase the convenience of detecting whether the entire infusion bottle 800 has a leak. For example, after completing the detection of whether the bottle head of the infusion bottle 800 has a leak, the chain transmission mechanism can naturally flip the infusion bottle 800 during operation to expose the bottom of the bottle and make electrical contact with the first electrode 200. The infusion bottle 800 can be flipped smoothly and reliably without setting an additional flipping mechanism, so as to achieve natural switching of multiple detection positions of the infusion bottle 800. Of course, in addition to the aforementioned chain transmission mechanism, the transmission unit 500 can also adopt a flip conveyor belt mechanism, etc., and the embodiment of the present application does not make specific restrictions on this, as long as the synchronous rotation of the mounting plate 100, the first electrode 200 and the infusion bottle 800 can be achieved.

[0034] In the embodiment of the present application, the first electrode 200 is connected to the mounting plate 100 through the bottle supporting assembly 300, so that the first electrode 200 is arranged to float in the radial direction of the mounting plate 100. Specifically, the first electrode 200 has a first state and a second state. It can be understood that the positions corresponding to the first electrode 200 in the first state and the second state are not the same. In the first state, the first electrode 200 is distributed on the radial inner side of the mounting plate 100, and the first electrode 200 at this time is separated from the bottom of the infusion bottle 800 transmitted by the transmission unit 500. In the second state, the first electrode 200 is distributed on the radial outer side of the mounting plate 100, and the first electrode 200 at this time is in contact with the bottom of the infusion bottle 800, and the bottom of the infusion bottle 800 is accommodated in the accommodating space 210, that is, the first electrode 200 in the second state establishes electrical contact with the bottom of the infusion bottle 800, and the first electrode 200 moves in the radial direction of the mounting plate 100 to switch between the first state and the second state. It should be noted that, in the initial state, the first electrode 200 is in a first state separated from the bottom of the infusion bottle 800 .

[0035] In the embodiment of the present application, the push member is connected to the bottle supporting assembly 300, and the push member is used to push the first electrode 200 to move along the radial direction of the mounting disk 100, so that the first electrode 200 switches from the first state to the second state. Exemplarily, in the embodiment of the present application, since the first electrode 200 and the bottle supporting assembly 300 rotate together with the mounting disk 100, the push member can be a cam fixedly arranged relative to the mounting disk 100, and the middle part of the mounting disk 100 is provided with an avoidance hole penetrating the mounting disk 100, and the rod connected to the cam can pass through the avoidance hole to realize the fixed installation of the cam relative to the mounting disk 100, so as to avoid the interference between the cam and the rotating mounting disk 100, and when the chain transmission mechanism drives the bottle supporting assembly 300 to rotate to a position against the cam, the cam can push the first electrode 200 to move radially outward, so that the first electrode 200 contacts the bottom of the infusion bottle 800, and the bottom of the infusion bottle 800 is accommodated in the accommodation space 210.

[0036] In an embodiment of the present application, the second electrode 700 is fixedly arranged relative to the mounting plate 100. Exemplarily, the second electrode 700 can be a positive electrode spring or a positive electrode brush, which can be fixedly arranged on the frame of the entire synchronous detection device through a connecting rod. The second electrode 700 is used to contact the bottle body of the infusion bottle 800. When the first electrode 200 contacts the bottom of the infusion bottle 800 and the second electrode 700 contacts the body of the infusion bottle 800, it is possible to detect whether there is leakage at the bottom of the infusion bottle 800.

[0037] Specifically, when the bottom of the bottle is intact, the infusion bottle 800, as an insulator, forms a capacitor between the first electrode 200 and the second electrode 700. The capacitance value between the first electrode 200 and the second electrode 700 is large, and the induced microcurrent generated is relatively small; when the bottom of the bottle is damaged and leaking, the capacitance formed between the infusion bottle 800 and the first electrode 200 and the second electrode 700 will disappear or decrease, and a loop will be formed between the first electrode 200 and the second electrode 700. At this time, the microcurrent generated increases, and the generated microcurrent can be measured by the detection circuit to determine whether the infusion bottle 800 leaks at the bottom of the bottle. It should be noted that when the second electrode 700 contacts the body of the infusion bottle 800, the infusion bottle 800 is in a posture with the bottle head facing up and the bottle bottom facing down. In this way, the infusion bottle 800 can be filled with liquid at its bottom, which is conducive to detecting and determining whether the bottle bottom is leaking.

[0038] During the research process, the inventors found that if the detection electrode is in instantaneous contact with the detection part of the infusion bottle 800, it is impossible to ensure stable and sufficient contact between the detection electrode and the detection part. Since the contact time is short, tiny leakage points cannot be fully detected, resulting in unreliable detection results and affecting the accuracy of leakage detection. Moreover, due to the instability of instantaneous contact, the contact state between the detection electrode and the bottom of the bottle may be different each time the detection is performed, which will lead to poor repeatability of the detection results. Even for the same infusion bottle 800, there may be large differences in the detection results of different times.

[0039] In the embodiment of the present application, when the transmission unit 500 drives the infusion bottle 800 to rotate around the outer circumference of the mounting plate 100 through the clamp 600, and can drive the mounting plate 100 to rotate synchronously, the bottle holding assembly 300 and the pushing member arranged on the mounting plate 100 move relative to each other, and the pushing member pushes the bottle holding assembly 300 to move in a radially outward direction, and then pushes the first electrode 200 to move in a radially outward direction, so that the first electrode 200 can stably contact the bottom of the infusion bottle 800, and the transmission unit 500 can drive the infusion bottle 800 to move synchronously with the first electrode 200. This synchronous movement method can establish electrical contact between the first electrode and the bottom of the infusion bottle in advance, so that the first electrode 200 and the bottom of the infusion bottle 800 have sufficient electrical contact time to avoid instantaneous contact, thereby enhancing the accuracy of bottle bottom leakage detection.

[0040] In the examples of this application, please continue to refer to Figure 1 , Figure 2 and Figure 4The bottle supporting assembly 300 includes a sleeve 310, a guide rod 320, an elastic member 330 and an adapter 340, wherein the sleeve 310 is fixedly arranged on the mounting plate 100 and the sleeve 310 is extended in the radial direction of the mounting plate 100, the guide rod 320 is movably inserted into the sleeve 310, and both ends of the guide rod 320 have portions exposed from the sleeve 310, the adapter 340 is connected to the radial outer end of the guide rod 320, the first electrode 200 can be installed based on the adapter 340, that is, the first electrode 200 is connected to the adapter 340, the elastic member 330 connects the sleeve 310 and the adapter 340, illustratively, the elastic member 330 can be a spring, and under the elastic action of the elastic member 330, the first electrode 200 is in a first state separated from the bottom of the infusion bottle 800.

[0041] Based on the above technical solution, when the mounting plate 100 rotates, the radial inner end of the guide rod 320 gradually abuts against the push piece and moves radially outward, so that the first electrode 200 connected to the guide rod 320 switches from the first state to the second state. Since the infusion bottle 800 and the bottle support assembly 300 rotate coaxially and synchronously, during the radial outward movement of the first electrode 200, the first electrode 200 can accurately and stably contact the bottom of the infusion bottle 800. This stable contact can avoid poor contact or disconnection caused by vibration or shaking, thereby ensuring the stability and reliability of infusion bottle bottom leakage detection.

[0042] After the detection is completed, as the mounting plate 100 continues to rotate, the radial inner end of the guide rod 320 gradually separates from the pushing member, the elastic member 330 restores its deformation and pulls the adapter 340 in the radial inward direction, so that the first electrode 200 installed on the adapter 340 is gradually separated from the bottom of the infusion bottle 800, that is, the first electrode 200 is reset from the second state to the first state.

[0043] For further technical solutions, see Figure 4 and Figure 5 The bottle supporting assembly 300 further includes a guide member 350 , which is connected to the radial inner end of the guide rod 320 . The mounting plate 100 is provided with a plurality of guide grooves 110 extending in a radial direction thereof, and the guide member 350 is guided and fitted in the guide grooves 110 .

[0044] In some embodiments of the present application, the guide member 350 can be a slider that slides in the guide groove 110. Through the setting of the guide member 350, the stability of the guide rod 320 moving in the radial direction can be improved, avoiding large shaking or swinging that may cause the first electrode 200 and the infusion bottle 800 to be inaccurately docked, and the bottom of the infusion bottle 800 cannot be stably accommodated in the accommodating space 210. That is, the setting of the guide member 350 can ensure that the bottom of the infusion bottle 800 is in stable electrical contact with the first electrode 200.

[0045] In some embodiments of this application, see Figure 4 and Figure 5 The guide member 350 can also be a first guide wheel rotatably arranged at the radial inner end of the guide rod 320, and the first guide wheel rollingly fits in the aforementioned guide groove 110. Compared with the sliding fit, the rolling fit of the first guide wheel in the guide groove 110 can effectively reduce friction and wear, and improve the smoothness of the movement of the first electrode 200 in the radial direction of the mounting disk 100. At the same time, the rolling contact can significantly reduce the noise level compared with the sliding contact.

[0046] In a further technical solution, based on the guide member 350 being arranged at the radial inner end of the guide rod 320, along the radial outward direction of the mounting plate 100, the guide member 350 is limitedly matched with the radial inner end of the sleeve 310, or the guide member 350 can be limitedly matched with the inner wall surface of the guide groove 110. In this way, when the push member pushes the guide rod 320 to move radially outward to switch the first electrode 200 from the first state to the second state, the guide member 350 can prevent the guide rod 320 from excessively moving and detaching from the mounting plate 100, thereby improving the stability and reliability of the first electrode 200 contacting and separating with the bottom of the infusion bottle 800.

[0047] In a further technical solution, the synchronous detection device may further include a mounting member 360 , which is connected to the adapter 340 . The first electrode 200 can be mounted on the mounting member 360 , and the first electrode 200 is loosely fitted in the mounting member 360 . It should be noted that, in the embodiment of the present application, the first electrode 200 cooperates with the mounting member 360 so that the first electrode 200 can swing relative to the mounting member 360. In this way, when the first electrode 200 moves radially outward to switch to the second state, the first electrode 200 in the second state has a certain swing margin. When the shape of the bottom of the infusion bottle 800 changes slightly, or the clamping posture of the infusion bottle 800 in the clamp 600 changes slightly, the first electrode 200 with the swing margin can more flexibly adapt to such changes of the infusion bottle 800, so that the bottom of the infusion bottle 800 can be stably accommodated in the accommodating space 210 and maintain a good contact state, thereby establishing a stable electrical connection relationship, thereby ensuring the stability and reliability of the detection; at the same time, based on the shaking setting of the first electrode 200, it can ensure that the contact pressure is neither too large nor too small, thereby avoiding damage to the bottle bottom or causing poor contact.

[0048] It can be understood that in the embodiment of the present application, the size of the accommodating space 210 should be larger than the size of the bottom of the infusion bottle 800, so that the first electrode 200 can better adapt to the bottoms of infusion bottles 800 of different sizes. Within a certain range, no matter how the diameter of the infusion bottle 800 changes, the first electrode 200 can ensure good contact with the bottom of the bottle by slight shaking.

[0049] In some embodiments of the present application, the mounting member 360 can be fixedly connected to the adapter 340, so that the position of the first electrode 200 in the second state is relatively displaced, thereby enabling leakage detection of the bottom of the infusion bottle 800 of the same size.

[0050] In some embodiments of the present application, the position of the mounting member 360 relative to the adapter 340 can be adjusted. In this way, the relative position relationship between the first electrode 200 and the bottom of the infusion bottle 800 in the first state or the second state can be adjusted by adjusting the position of the mounting member 360 relative to the adapter 340, thereby achieving compatibility with infusion bottles 800 of different sizes.

[0051] Specifically, see Figure 4 and Figure 5 , the adapter 340 includes an adapter body 341 and a slide rail 342 connected to the adapter body 341. For example, the two can be fastened together by a threaded connector, wherein the adapter body 341 is connected and fixed to the radial outer end of the guide rod 320, and the slide rail 342 is extended along the radial direction of the mounting plate 100, and the aforementioned mounting member 360 can slide on the slide rail 342 and be locked. For example, see Figure 4 The mounting member 360 has two clamping parts 361 arranged opposite to each other, and the two clamping parts 361 are clamped on both sides of the slide rail 342, that is, the mounting member 360 is clamped on the slide rail 342, and the threaded connection member 362 connects the two clamping parts 361. By rotating the threaded connection member 362, the two clamping parts 361 can be clamped close to or released away from the slide rail 342. When it is necessary to adjust the position of the first electrode 200, the threaded connection member 362 can be loosened, and the position of the mounting member 360 on the slide rail 342 can be slid to adjust. After reaching the target position, the threaded connection member 362 can be tightened.

[0052] As can be seen from the foregoing, the push member of the embodiment of the present application can be a cam (not shown in the figure), and the cam can abut against the radial inner end of the guide rod 320. In further technical solutions, please refer to Figure 4 The bottle supporting assembly 300 may further include a second guide wheel 380, which is rotatably arranged at the radial inner end of the guide rod 320. For example, the first guide wheel and the second guide wheel 380 may be coaxially arranged, the first guide wheel is located in the guide groove 110, and the second guide wheel 380 is located outside the guide groove 110. The outer edge of the cam may abut against the second guide wheel 380, so that the guide rod 320 moves in the radial direction of the mounting plate 100. This layout, through the distributed arrangement of the first guide wheel and the second guide wheel 380, can significantly improve the smoothness of the movement of the first electrode 200 in the radial direction, effectively reduce friction, and reduce the generation of noise.

[0053] The embodiment of the present application also discloses an infusion bottle leakage detection device. The disclosed infusion bottle leakage detection device includes the aforementioned infusion bottle bottom leakage synchronous detection device, so that the infusion bottle leakage detection device can realize leakage detection on the bottom of the infusion bottle 800. The first electrode 200 moves synchronously with the infusion bottle 800, which can ensure the contact time between the first electrode 200 and the bottom of the infusion bottle 800, thereby enhancing the accuracy of the bottom leakage detection.
