Description

Technical Field

[0001] The present invention relates to the technical field of medical product detection equipment, and in particular to an infusion bag tunnel hole leakage detection device and an infusion bag leakage detection device. Background Art

[0002] The sealing performance of pharmaceutical packaging (such as infusion bottles, infusion bags, etc.) is directly related to the stability and safety of the drugs. Once the pharmaceutical packaging leaks, external microorganisms or contaminants may enter the packaging, causing the drugs to be contaminated. Therefore, it is usually necessary to conduct sealing tests on pharmaceutical packaging.

[0003] In medical environments, infusion bags are widely used. If an infusion bag leaks, the pollutants inside it may spread to the surrounding environment through the leak point, and then contaminate other drugs or medical equipment. In the related art, there is an infusion bag, in which there is a neck position between the combined cover and the bag body. The connection between the neck position and the bag body is often called a "tunnel hole". When leak detection of infusion bags is performed in the related field, the combined cover and the bag body are often tested for leaks. However, due to the small diameter and long hole of the tunnel hole, during conventional discharge detection, the discharge electrode does not have sufficient contact with the part where the tunnel hole is located, making it difficult to detect the leak at that location, which in turn causes the infusion bag to have a very high risk of drug contamination.

[0004] Therefore, providing a device capable of detecting leakage of tunnel holes in infusion bags is a technical problem to be solved urgently by those skilled in the art. Summary of the invention

DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. 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.

[0022] See also Figure 1 In the related art, the infusion bag 500 generally includes a combined cover 510 and a bag body 520. The combined cover 510 is generally connected to the bag body 520 by a fusion sealing method, and a neck 530 is formed inside the bag body 520. It can be understood that the neck 530 is fusion sealed and embedded in the bag body 520. Please continue to refer to Figure 1 , the part where the neck 530 is connected to the bag body 520 ( Figure 1 The part indicated by the dotted line in the middle is often referred to as the tunnel hole 540 by those skilled in the art. The inventor found in the research process that when leak detection is performed on the infusion bag 500 in the related field, the combined cover 510 and the bag body 520 are usually tested for sealing to determine whether there is leakage in these parts, but the sealing test of the tunnel hole 540 is often ignored. If the infusion bag 500 leaks in the tunnel hole 540, the medicine in the infusion bag 500 may also be contaminated.

[0023] Based on the above situation, the embodiment of the present application discloses an infusion bag tunnel hole leakage detection device and an infusion bag leakage detection device. Figures 1 to 7 , the infusion bag tunnel hole leakage detection device and the infusion bag leakage detection equipment provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The embodiment of the present application discloses a tunnel hole leakage detection device for an infusion bag. The disclosed tunnel hole leakage detection device for an infusion bag is applied to an infusion bag leakage detection device to serve as a detection station in the infusion bag leakage detection device for detecting whether there is leakage in the tunnel hole 540. Specifically, the tunnel hole leakage detection device for an infusion bag includes a frame, a conveying unit 100, a fixture 200, and a driving module 300. The frame can serve as an installation base for the conveying unit 100, the fixture 200, and the driving module 300, that is, the conveying unit 100, the fixture 200, and the driving module 300 are arranged on the frame.

[0025] Among them, the conveying unit 100 is used to convey the infusion bag 500. Exemplarily, the conveying unit 100 can be a belt transmission mechanism, and the infusion bag 500 can be carried on the conveyor belt of the belt transmission mechanism and conveyed. A detection station for detecting whether there is a leakage at the tunnel hole 540 is arranged on the conveying path of the conveying unit 100. In the embodiment of the present application, in order to facilitate subsequent writing, the conveying direction of the conveying unit 100 is defined as the first direction.

[0026] In an embodiment of the present application, the clamp 200 and the driving module 300 are arranged on the conveying path of the conveying unit 100, and the clamp 200 and the driving module 300 can be distributed on the same side of the conveying unit 100. The clamp 200 is movably arranged along a first direction. The driving module 300 is connected to the clamp 200 to drive the clamp 200 to move along the first direction. The clamp 200 is used to clamp the area of ​​the neck 530 of the infusion bag 500 corresponding to the tunnel hole 540. Based on the driving action of the driving module 300, when the infusion bag 500 is conveyed along the conveying unit 100, the clamp 200 can move synchronously with the infusion bag 500.

[0027] In the examples of this application, see Figure 2 , Figure 4 and Figure 6 The clamp 200 is electrically connected with a first electrode 600. For example, the first electrode 600 can be a positive electrode. When the clamp 200 clamps the neck 530, the first electrode 600 can establish electrical contact with the location of the tunnel hole 540 through the clamp 200. When the tunnel hole 540 is leak tested, the neck 530 can be continuously discharged with high voltage through the clamp 200. It should be noted that the tunnel hole leakage detection device of the infusion bag of the embodiment of the present application should also include a second electrode 700. The second electrode 700 is connected to the frame and is used to contact the bag body of the infusion bag 500. For example, the second electrode 700 can be a negative electrode, and the second electrode 700 can be in the form of a brush or an electrode shrapnel. When the clamp 200 clamps the neck 530, the second electrode 700 contacts the bottle body of the infusion bag 500.

[0028] See also Figure 4 and Figure 6The clamp 200 includes a first driving member 290, a first clamp arm 210 and a second clamp arm 220. The first clamp arm 210 and the second clamp arm 220 are arranged opposite to each other and can approach or move away from each other under the driving action of the first driving member 290 to clamp or release the neck 530 of the infusion bag 500. Exemplarily, the first driving member 290 can be an electric push rod or a cylinder, and this embodiment does not make specific restrictions on this. The first clamp arm 210 is located above the second clamp arm 220. One of the first clamp arm 210 and the second clamp arm 220 is provided with a first pressing block 230, and the other is provided with a second pressing block 240. The first clamp arm 210 and the second clamp arm 220 clamp the neck 530 through the first pressing block 230 and the second pressing block 240.

[0029] For example, please see Figure 4 and Figure 6 The first pressing block 230 is arranged on the first clamping arm 210, and the second pressing block 240 is arranged on the second clamping arm 220. The first pressing block 230 is provided with a first recess 231, and the second pressing block 240 is provided with a second recess 241. The first pressing block 230 is opposite to the second pressing block 240. When the first driving member 290 drives the first clamping arm 210 and the second clamping arm 220 to approach each other so that the clamp 200 is in a clamping state, the first recess 231 and the second recess 241 correspond to and enclose to form a receiving hole for clamping the neck 530 of the infusion bag 500. That is to say, when the clamp 200 is in a clamping state, the first pressing block 230 and the second pressing block 240 jointly clamp and fix the infusion bag 500 at a position corresponding to the tunnel hole 540. In an optional embodiment, the first electrode 600 can be electrically connected to the second pressing block 240, thereby electrically contacting the neck 530.

[0030] Based on the above scheme, when the infusion bag 500 moves on the conveying unit 100, the clamp 200 can clamp the part of the infusion bag 500 where the tunnel hole 540 is located, and the driving module 300 can drive the clamp 200 to move synchronously with the infusion bag 500. In this way, the clamp 200 can be in electrical contact with the neck 530 of the infusion bag 500 for a long time. At this time, the first electrode 600 can continuously discharge and act on the part where the tunnel hole 540 is located through the clamp 200. When high voltage electricity is released for a long time, the accuracy of the leakage detection of the tunnel hole 540 can be enhanced, and it can be accurately judged whether there is a leakage at the tunnel hole 540. In addition, by clamping the first pressure block 230 and the second pressure block 240, it can be ensured that the clamp 200 has sufficient contact time and contact area with the neck of the infusion bag 500, thereby ensuring the accuracy of the tunnel hole detection.

[0031] In a further technical solution, the second pressing block 240 is provided with a first guide wheel 250 on one side of the second recess 241, and the second pressing block 240 is provided with a second guide wheel 260 on the other side of the second recess 241, one of the first guide wheel 250 and the second guide wheel 260 is fixedly arranged, and the other is floatingly arranged along the first direction. For example, see Figure 4 The first guide wheel 250 is fixedly arranged, and the second guide wheel 260 is floatingly arranged. In this way, when the first driving member 290 drives the first pressing block 230 and the second pressing block 240 to clamp the neck 530, the fixedly arranged first guide wheel 250 can play a positioning role for the neck 530, and when the posture of the infusion bag 500 on the conveying unit 100 changes, based on the floating design of the second guide wheel 260, even if the posture of the infusion bag 500 on the conveying unit 100 changes slightly, the floatingly designed second guide wheel 260 can allow the neck 530 of the infusion bag 500 to be stuck in the accommodating hole, and can play a certain corrective role on the neck 530 of the infusion bag 500 with changed posture, so as to ensure that the tunnel hole 540 can be accurately and stably leak detected. That is to say, the floatingly designed second guide wheel 260 in the present application can significantly improve the fault tolerance rate of the clamp 200 for clamping the infusion bag 500.

[0032] In some embodiments of this application, please continue to refer to Figure 2 and Figure 4 The clamp 200 further includes an elastic member 270 and a baffle 280, wherein the baffle 280 is rotatably disposed on the second clamp arm 220 and is disposed adjacent to the second pressing block 240, the aforementioned second guide wheel 260 is rotatably disposed on the baffle 280, the elastic member 270 may be a torsion spring, the torsion spring may be sleeved on the rotation axis of the baffle 280 relative to the second clamp arm 220, one end of the elastic member 270 abuts against the second clamp arm 220, and the other end of the elastic member 270 abuts against the baffle 280, based on the elastic effect of the elastic member 270, the second guide wheel 260 abuts against the location of the tunnel hole 540 of the infusion bag 500. In some optional embodiments of the present application, the aforementioned first electrode 600 may be in electrical contact with the neck 530 through the baffle 280 and the second guide wheel 260.

[0033] Based on the above scheme, under the transportation of the conveying unit 100, the infusion bag 500 can be moved to the tunnel hole detection station, and the clamp 200 can be switched from the open state to the clamping state under the drive of the first driving member 290 to clamp the neck 530 where the tunnel hole 540 is located. When the first electrode 600 and the second electrode 700 are both in electrical contact with the infusion bag 500, the first electrode 600 performs continuous discharge detection on the location of the tunnel hole 540. If the posture of the infusion bag 500 is not consistent, the elastic member 270 can adaptively undergo elastic deformation and allow the neck 530 of the infusion bag 500 to be stuck in the accommodating hole, and can apply a certain restraining force to the neck 530 through the second guide wheel 260, so that the neck 530 is not easy to shake and the accuracy of the detection is ensured.

[0034] Based on the above scheme, the second guide wheel 260 is arranged on the second clamping arm 220 through the elastic member 270 and the baffle 280, so that the second guide wheel 260 has a certain elastic floating margin in the first direction. When the neck 530 of the infusion bag 500 is clamped in the second recess 241, the second guide wheel 260 can adapt and adjust through its floating property, so as to stably hold against the neck 530 of the infusion bag 500, and at the same time ensure that the neck 530 of the infusion bag 500 can be smoothly and stably clamped by the first pressure block 230 and the second pressure block 240. This design reduces the problem of difficult or unstable accommodation caused by differences in the shape or posture of the infusion bag 500. That is to say, the leakage detection device of the infusion bag tunnel hole 540 of the embodiment of the present application has strong compatibility with the neck 530 of the infusion bag 500 with different postures, different sizes or different loading amounts.

[0035] For further technical solutions, please continue to refer to Figure 4 The first depression 231 and the second depression 241 are respectively two distributed along the first direction, and the two second guide wheels 260 are distributed on both sides of the first guide wheel 250, that is, when the first pressing block 230 and the second pressing block 240 are clamped relative to each other, two receiving holes distributed along the first direction can be formed, and the two receiving holes share one first guide wheel 250 to position the infusion bag 500. In this way, when the first clamp arm 210 and the second clamp arm 220 move toward each other to clamp the position where the tunnel hole 540 is located, even if the infusion bag 500 is tilted greatly, its neck 530 is easy to be located in one of the two receiving holes, and the two corresponding first depressions 231 and second depressions 241 can provide double clamping points. Even if the infusion bag 500 deviates or fails at one of the clamping points, the other clamping point can still ensure that the neck 530 of the infusion bag 500 is firmly clamped.

[0036] It should be noted that the first pressing block 230 has an arc-shaped transition between the two first recesses 231, and the second pressing block has an arc-shaped transition between the two second recesses 241. In this way, the neck 530 can automatically slide into one of the two accommodating holes, which can effectively prevent the first pressing block 230 and the second pressing block 240 from damaging the neck 530.

[0037] In the embodiment of the application, the driving module 300 includes a base plate 310, a mounting plate 320, a second driving member 350 and a gear rack transmission mechanism, wherein a guide rail 340 extending in a first direction is provided on the base plate 310, the mounting plate 320 is slidably matched with the base plate 310 through the guide rail 340, and the second driving member 350 is connected to the mounting plate 320 through the gear rack transmission mechanism to drive the mounting plate 320 to move in the first direction, and the aforementioned clamp 200 can be provided on the mounting plate 320, so as to achieve synchronous movement of the clamp 200 and the infusion bag 500. The second driving member 350 in the embodiment of the present application can be a motor, the gear in the gear rack transmission mechanism can be connected to the output shaft of the motor, the rack in the gear rack transmission mechanism can be provided on the mounting plate 320 and extend in the first direction, and the mounting plate 320 moves in the first direction when the motor rotates. Of course, in addition to the aforementioned gear rack transmission mechanism, the driving module 300 may also adopt an electric push rod, a cylinder or a hydraulic cylinder, etc., and the present application does not impose any specific restrictions on this, as long as the synchronous movement of the clamp 200 and the infusion bag 500 can be achieved. It should be noted that the driving module 300 in the embodiment of the present application may also include a drag chain 330 to facilitate the wiring harness connected to the clamp 200 to move with the clamp 200.

[0038] It should be noted that when leak detection is performed at the tunnel hole 540, the detection part of the infusion bag 500 needs to be filled with liquid. When the detection part is filled with liquid, the conductivity of the liquid will affect the path and intensity of the current, thereby more accurately reflecting the leakage situation. If there is no liquid in the detection part, it may not be possible to accurately determine whether the package is leaking. Based on this situation, in the embodiment of the present application, the conveying unit 100 is tilted from its second side to its first side, that is, the height of the conveying unit 100 on the second side is higher than the height of the first side. When the infusion bag 500 is placed on the conveying unit 100, the infusion bag 500 is tilted toward one side of the combination cover 510, so that the liquid in the infusion bag 500 can fill the detection part, thereby improving the accuracy of the detection.

[0039] For further technical solutions, see Figure 7The leakage detection device for the infusion bag tunnel hole 540 may also include a bag pressing conveyor line 400, which is arranged above the conveying unit 100. A gap is formed between the bag pressing conveyor line 400 and the conveying unit 100 for the infusion bag 500 to pass through. The bag pressing conveyor line 400 moves synchronously with the conveying unit 100. When the infusion bag 500 passes through the gap, the conveying unit 100 and the bag pressing conveyor line 400 can clamp the infusion bag 500 to a certain extent. On the one hand, the bag pressing conveyor line 400 The infusion bag 500 is pressed tightly against the conveying unit 100 by a certain pressure to prevent it from shaking or shifting during transportation. On the other hand, based on the downward pressure of the bag pressing conveyor line 400, there is a large static friction between the infusion bag 500 and the conveying unit 100 and the bag pressing conveyor line 400, which can ensure that the infusion bag 500 can move in sync with the clamp 200, thereby ensuring that the infusion bag 500 maintains a relatively certain posture during the detection process, thereby ensuring the accuracy of the detection.

[0040] The embodiment of the present application also discloses an infusion bag leakage detection device, including the aforementioned infusion bag tunnel hole leakage detection device.
