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 and Figure 2In the related art, the infusion bag 1100 usually includes a bag body 1110 and a combined cover 1120 connected to the bag body 1110. The combined cover 1120 is usually connected to the bag body 1110 by welding and is formed with a neck 1130 located inside the bag body 1110. It can be understood that the neck 1130 is welded and embedded in the bag body 1110.

[0023] In one form of infusion bag 1100, see Figure 1 The neck 1130 is formed with a tube wing portion at the junction with the bag body 1110 ( Figure 1 The detection equipment in the related art usually detects the tube wing part of the infusion bag 1100. In another form of the infusion bag 1100, see Figure 2 The neck 1130 has a hole formed at the junction with the bag body 1110 ( Figure 2 The area indicated by the dotted line in the middle is often referred to as a tunnel hole by those skilled in the art. When leak detection is performed on the infusion bag 1100 in the related field, the bag body 1110 and the combination cover 1120 are usually tested for sealing to determine whether there is a leak in these areas. However, the sealing test of the tunnel hole is often ignored. If the infusion bag 1100 leaks in the tunnel hole, there is a risk of contamination of the medicine in the infusion bag 1100.

[0024] Based on the above situation, the present application embodiment discloses an infusion bag leakage detection device. Figures 3 to 12 , the infusion bag leakage detection device provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The embodiment of the present application discloses an infusion bag leakage detection device, which includes a frame 100, a first conveyor line 200, a combination cover detection module 300, a tunnel hole detection module 400 and a second conveyor line 500, wherein the frame 100 is the basic component of the entire infusion bag leakage detection device, and can provide an installation basis for the first conveyor line 200, the combination cover detection module 300, the tunnel hole detection module 400 and the second conveyor line 500, that is, the first conveyor line 200, the combination cover detection module 300, the tunnel hole detection module 400 and the second conveyor line 500 are all arranged on the frame 100.

[0026] Among them, along the conveying direction of the first conveyor line 200, the combination cover detection module 300 and the tunnel hole detection module 400 are respectively arranged on the first side of the first conveyor line 200 to form a combination cover detection station and a tunnel hole detection station on the frame 100. Exemplarily, the first conveyor line 200 can be a belt conveyor line, and the height of the first conveyor line 200 on its second side is higher than its height on the first side. The first side and the second side can be the left and right sides of the conveying direction of the first conveyor line 200. That is to say, the first conveyor line 200 is tiltedly arranged on the frame 100. When the infusion bag 1100 is carried on the first conveyor line 200, the head of the infusion bag 1100 faces the first side, and the tail of the infusion bag 1100 faces the second side. In this way, it can ensure that the liquid in the infusion bag 1100 is filled at the head position of the infusion bag 1100, and the combined cover and tunnel hole of the infusion bag 1100 are located at the head position of the infusion bag 1100. This tilted conveying method is convenient for discharge detection of the combined cover and tunnel hole of the infusion bag 1100.

[0027] In the embodiment of the present application, the second conveyor line 500 is arranged above the first conveyor line 200. For example, the second conveyor line 500 may also be a belt conveyor line. The second conveyor line 500 is arranged parallel to the first conveyor line 200. The second conveyor line 500 may also be arranged obliquely on the frame 100 accordingly. In the embodiment of the present application, a gap is formed between the second conveyor line 500 and the first conveyor line 200 for the infusion bag 1100 to pass through. When the infusion bag 1100 passes through the gap, the first conveyor line 200 and the second conveyor line 500 can play a certain clamping role on the infusion bag 1100, that is, the infusion bag 1100 is supported on the first conveyor line 200 and pressed down by the second conveyor line 500.

[0028] Based on the above technical solution, the second conveyor line 500 presses the infusion bag 1100 against the first conveyor line 200 with a certain pressure, which can prevent the infusion bag 1100 from shaking or shifting significantly during the conveying process and causing posture changes, that is, the stability of the posture of the infusion bag 1100 can be ensured, and based on the downward pressure of the second conveyor line 500, there is a large static friction between the infusion bag 1100 and the first conveyor line 200, which can ensure that the infusion bag 1100 can keep the same pace as the first conveyor line 200. In other words, by setting the second conveyor line 500, it can be ensured that the infusion bag 1100 maintains a stable speed and a relatively certain posture during the detection process, thereby ensuring the accuracy of the detection.

[0029] At the same time, by arranging a combination cover detection module 300 and a tunnel hole detection module 400 on the frame 100 to detect the combination cover and tunnel hole positions of the infusion bag 1100, compared with the traditional detection equipment that mainly detects the bag body of the infusion bag 1100, it can avoid ignoring the leakage detection of the tunnel hole, thereby reducing the risk of drug contamination of the infusion bag 1100.

[0030] In the examples of this application, see Figure 4 , Figure 8 , Fig. 9 and Fig.14 The combined cover detection module 300 includes a wheel-shaped electrode 310, a mounting plate 320 and a first driving mechanism 330, wherein the mounting plate 320 can be fixed on the frame 100, the two wheel-shaped electrodes 310 are arranged opposite to each other and rotatably arranged on the mounting plate 320, and the first driving mechanism 330 is used to drive the two wheel-shaped electrodes 310 to rotate synchronously in opposite directions. Exemplarily, the first driving mechanism 330 can be a gear transmission mechanism driven by a motor.

[0031] In the embodiment of the present application, the wheel-shaped electrode 310 is provided with teeth 311 distributed along its circumference, and an inwardly recessed discharge electrode surface 312 is provided between two adjacent teeth 311. When the infusion bag 1100 is conveyed through the combination cover detection station, the two wheel-shaped electrodes 310 rotate synchronously in opposite directions, and the discharge electrode surfaces 312 rotate to adapt to the movement of the combination cover. The two wheel-shaped electrodes 310 receive the combination cover part of the infusion bag 1100 through the recessed discharge electrode surfaces 312, and the combination cover is accommodated in the space enclosed by the two discharge electrode surfaces 312. The discharge electrode surfaces 312 can be close to the outer periphery of the combination cover. The continuous discharge of the two discharge electrode surfaces 312 can form a stable electric field distribution, and the circumference of the combination cover can be comprehensively detected, thereby ensuring the accuracy of the detection results, and having the characteristics of convenient detection and high accuracy.

[0032] In a further technical solution, the two discharge electrode surfaces 312 are arc surfaces, and the central angle of the discharge electrode surfaces 312 is less than 180°. The arc surface design less than 180° enables the two discharge electrode surfaces 312 to have a larger opening. When the combined cover slowly enters between the two discharge electrode surfaces 312, even if the position and size of the combined cover are slightly deviated, it will not directly collide with or get stuck with the wheel-shaped electrode 310, thereby protecting the integrity of the combined cover and the wheel-shaped electrode 310. It can be understood that if the cross-section of the combined cover is other shapes, such as a rectangle, an ellipse, etc., the shape of the discharge electrode surface 312 should be compatible with the outer peripheral contour of the combined cover.

[0033] In an embodiment of the present application, the tunnel hole detection module includes a second driving mechanism and a clamp connected to the second driving mechanism, wherein the second driving mechanism is used to drive the clamp to move synchronously with the first conveyor line 200, and the clamp is used to clamp the neck position of the infusion bag 1100 to perform leakage detection on the tunnel hole of the infusion bag 1100. The second driving mechanism drives the clamp to move synchronously with the infusion bag 1100. Exemplarily, the second driving mechanism can be a sliding mechanism driven by a motor, a cylinder, a hydraulic cylinder or an electric push rod to drive the clamp to move in a first direction. The second driving mechanism is used to make the clamp move synchronously with the infusion bag 1100, so that the clamp can be in electrical contact with the neck of the infusion bag 1100 for a long time. The clamp can continuously discharge and act on the location of the tunnel hole. When high voltage electricity is released for a long time, the accuracy of tunnel hole leakage detection can be enhanced.

[0034] Specifically, see Figure 8 , Fig.10 , Fig.11 , Fig.12 and Fig.13 The clamp includes a first clamp arm 410 and a second clamp arm 420 that are arranged opposite to each other. The first clamp arm 410 and the second clamp arm 420 can be driven by a driving member to approach each other to maintain a clamping state. For example, the driving member can be an electric push rod or a cylinder. One of the first clamp arm 410 and the second clamp arm 420 is provided with a first pressing block 430, and the other is provided with a second pressing block 440. For the convenience of subsequent text, please refer to Figure 1 The first pressing block 430 is arranged on the first clamping arm 410, and the second pressing block 440 is arranged on the second clamping arm 420. The first pressing block 430 is provided with a first recess 431, and the second pressing block 440 is provided with a second recess 441. The first pressing block 430 is opposite to the second pressing block 440. When the driving member drives the first clamping arm 410 and the second clamping arm 420 to approach each other and are in a clamping state, the first recess 431 and the second recess 441 correspond to and enclose to form a receiving hole for clamping the neck of the infusion bag 1100. The first pressing block 430 and the second pressing block 440 can be electrically connected to a power supply, that is, the discharge of the first pressing block 430 and the second pressing block 440 can be used to perform discharge detection on the tunnel hole.

[0035] In a further technical solution, the tunnel hole detection module also includes a first guide wheel 450, a second guide wheel 460 and an elastic member 470, wherein the first guide wheel 450 and the second guide wheel 460 are respectively arranged on both sides of the second recess 441, one of the first guide wheel 450 and the second guide wheel 460 is fixedly set, and the other is connected to the elastic member 470 to float in the first direction, and the first direction is the conveying direction of the first conveyor line 200. Exemplarily, the first guide wheel 450 is fixedly set, and the second guide wheel 460 is connected to the second clamping arm 420 or the second pressure block 440 through the elastic member 470 to float in the first direction. Exemplarily, the elastic member 470 can be a torsion spring.

[0036] Based on the above technical solution, when the first pressure block 430 and the second pressure block 440 clamp the neck of the infusion bag 1100, the fixed first guide wheel 450 can play a positioning role for the neck, and when the posture of the infusion bag 1100 on the first conveyor line 200 changes, based on the floating design of the second guide wheel 460, even if the posture of the infusion bag 1100 on the first conveyor line 200 changes slightly, the floating second guide wheel 460 can allow the neck of the infusion bag 1100 to be clamped in the accommodating hole, and can play a certain corrective role on the neck with changed posture, so as to ensure that the tunnel hole can be accurately and stably leaked. That is to say, the floating second guide wheel 460 in the present application can significantly improve the fault tolerance of the clamp clamping the infusion bag 1100.

[0037] For further technical solutions, please continue to refer to Fig.13 The first depression 431 and the second depression 441 are respectively two distributed along the first direction, and the two second guide wheels 460 are distributed on both sides of the first guide wheel 450, that is, when the first pressing block 430 and the second pressing block 440 are clamped relative to each other, two receiving holes distributed along the first direction can be formed, and the two receiving holes share a first guide wheel 450 to position the infusion bag 1100. In this way, when the first clamp arm 410 and the second clamp arm 420 move toward each other to clamp the neck position where the tunnel hole is located, even if the infusion bag 1100 is tilted greatly, its neck is easy to be located in one of the two receiving holes, and the two corresponding first depressions 431 and second depressions 441 can provide double clamping points. Even if the infusion bag 1100 deviates or fails at one of the clamping points, the other clamping point can still ensure that the part where the tunnel hole of the infusion bag 1100 is located is firmly clamped.

[0038] In some embodiments of the present application, the infusion bag leakage detection device also includes a tube wing detection module 600, which is arranged on the frame 100. Similarly, the tube wing detection module 600 is distributed on the first side of the first conveyor line 200. The tube wing detection module 600 is used to detect the tube wing of the infusion bag 1100. Exemplarily, the tube wing detection module 600 can be a first brush fixed on the frame 100. Under such a setting, the infusion bag leakage detection device of the present application can perform discharge detection on the infusion bag 1100 with a tunnel hole, and can also perform discharge detection on the infusion bag 1100 with a tube wing, and has good versatility.

[0039] In some embodiments of this application, see Figure 5 The infusion bag leakage detection device also includes a bag tail detection module 1200, which can be fixedly mounted on the frame 100 to form a bag tail detection station. Exemplarily, the bag tail detection module 1200 can be a second brush fixedly mounted on the frame 100 to realize discharge leakage detection of the tail of the infusion bag.

[0040] In a further technical solution, the infusion bag leakage detection device further includes a first lifting mechanism 700, which is connected to the second conveyor line 500 to adjust the gap between the first conveyor line 200 and the second conveyor line 500. The first lifting mechanism 700 can adjust the height of the second conveyor line 500 according to the size of the infusion bag 1100, so that the second conveyor line 500 can fit closely with infusion bags 1100 of various sizes. This design avoids the transportation problem caused by the size difference of the infusion bag 1100, so that the second conveyor line 500 can better play the role of holding the infusion bag 1100, and improves the compatibility and flexibility of the entire infusion bag leakage detection device; at the same time, the first lifting mechanism 700 reasonably adjusts the spacing between the first conveyor line 200 and the second conveyor line 500, so as to avoid excessive wear between the infusion bag 1100 and the first conveyor line 200. In the embodiment of the present application, the first lifting mechanism can be a screw lifting mechanism or a chain lifting mechanism, and the form of the first lifting mechanism 700 is not specifically limited in the present application.

[0041] In the examples of this application, see Figure 6 and Figure 7The infusion bag leakage detection device may further include a bag body detection module 800, the bag body detection module 800 includes a third conveyor line 810, a fourth conveyor line 820, a third brush 830 and a fourth brush 840, wherein the third conveyor line 810 is connected to the fourth conveyor line 820, exemplarily, the third conveyor line 810 and the fourth conveyor line 820 may be belt conveyor lines, both of which may use a plurality of spaced conveyor belts to convey the infusion bag 1100, wherein the third conveyor line 810 is configured to lift the infusion bag 1100 upward, the fourth conveyor line 820 is configured to lower the infusion bag 1100, and the third conveyor line 810 is connected to the fourth conveyor line 820 and is in an inverted V shape as a whole. When the infusion bag 1100 passes through the third conveyor line 810, the liquid in the infusion bag 1100 fills the rear part of the bag, so that the bubbles in the liquid float toward the front part of the bag, and the third brush 830 can pass through the gap area between the multiple conveyor belts to contact the rear part of the bag for discharge detection; and when the infusion bag 1100 passes through the fourth conveyor line 820, the liquid in the infusion bag 1100 fills the front part of the bag, so that the bubbles in the liquid float toward the rear part of the bag, and the fourth brush 840 can contact the front part of the bag for discharge detection. Through the up and down slope design of the third conveyor line 810 and the fourth conveyor line 820, the bubbles can float up and leave the detected area of ​​the bag, thereby ensuring the accuracy of the detection of the front part and the rear part of the bag.

[0042] In an embodiment of the present application, the infusion bag leakage detection equipment may also include a kick-out conveyor line 900 and a second lifting mechanism 1000. The kick-out conveyor line 900 may be arranged between the first conveyor line 200 and the bag body detection module 800. The kick-out conveyor line 900 may also be arranged at the rear end of the bag body detection module 800. The second lifting mechanism 1000 is connected to the kick-out conveyor line 900.

[0043] For example, see Figure 6 The kick-out conveyor line 900 can be a belt conveyor line connected to the first conveyor line 200, and the second lifting mechanism 1000 can be in the form of a cylinder, an electric push rod, etc. When a leakage point is detected in the infusion bag 1100, the second lifting mechanism 1000 can lift the kick-out conveyor line 900, so that the kick-out conveyor line 900 and the first conveyor line 200 are separated in height dislocation, so that the leaking infusion bag 1100 falls at the end of the first conveyor line 200 and is screened out. When there is no leakage in the infusion bag 1100, the kick-out conveyor line 900 and the first conveyor line 200 remain connected to allow the intact infusion bag 1100 to flow to the subsequent workstation.
