Description

Technical Field

[0001] The present invention belongs to the technical field of detection devices, and particularly relates to a sealing detection unit, a detection device, and a detection method for bag bodies such as medicine bags, food bags, and packaging bags. Background Art

[0002] An electronic micro pump is an infusion device that uses a controller to drive a motor to rotate, and can accurately, microscopically, evenly, and continuously infuse a liquid medicine into the body, greatly improving the accuracy, safety, and nursing quality of infusion, effectively reducing the workload of medical staff, and improving the work efficiency of medical staff. The electronic micro pump is usually used in conjunction with a medicine bag. The medicine bag is fixed to the electronic micro pump through a medicine bag bracket. The medicine bag stores the liquid medicine. The channel for the liquid medicine to enter and exit the medicine bag is a pump tube (connecting tube) connected to the medicine bag, and a standard joint is connected to the free end of the pump tube. The detection of the sealing performance of the medicine bag usually includes two parts. One part is the detection of the sealing performance of the medicine bag itself, and the other part is the detection of the sealing performance of the pump tube. Currently, the detection of the sealing performance of the medicine bag and the pump tube is carried out on different devices respectively, with cumbersome steps and low efficiency. Moreover, when detecting the pump tube, tightening the inflation end joint and clamping the pump tube with a stop flow clamp both require manual operation, resulting in high labor intensity, and it is also easy to have situations such as not tightening or clamping tightly, causing air leakage and resulting in detection errors, or over-tightening and damaging the tube end joint. Summary of the Invention

[0003] The purpose of the present invention is to provide a bag body sealing detection module, a detection device, and a detection method that can complete the sealing detection of the bag body and the connecting tube at one time.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A bag body sealing detection module, the bag body has a connecting tube communicated therewith, and the bag body sealing detection module includes: a bracket, on which a bag body placement groove for placing the bag body is provided, and a first pressure sensor is arranged in the bag body placement groove; an inflation mechanism, the inflation mechanism includes a sealed inflation joint connected to an air source and a tube body fixing position for fixing the connecting tube, the sealed inflation joint is docked with the connecting tube to inflate the connecting tube and the bag body, and a second pressure sensor is arranged on the sealed inflation joint; a tube pressing mechanism, the tube pressing mechanism includes a tube clamp for blocking the communication between the connecting tube and the bag body; a pressing plate mechanism, the pressing plate mechanism includes a limiting and stabilizing pressing plate, and the limiting and stabilizing pressing plate can press on the bag body for expansion limiting during inflation of the medicine bag and pressure balance after inflation.

[0006] As an improvement of the bag body sealing detection module of the present invention, the inflation mechanism further includes a joint driving unit for driving the movement of the sealing inflation joint. The tube body fixing position and the sealing inflation joint are arranged opposite to each other. The sealing inflation joint can be docked with the connecting tube or separated from the connecting tube under the control of the joint driving unit.

[0007] As an improvement of the bag body sealing detection module of the present invention, the tube pressing mechanism further includes a tube clamp driving unit for controlling the up and down movement of the tube clamp. When the tube clamp moves downward, it presses tightly on the connection between the connecting tube and the bag body to block the communication between the two. When it moves upward, the communication between the connecting tube and the bag body is restored.

[0008] As an improvement of the bag body sealing detection module of the present invention, the tube pressing mechanism further includes a tube clamp rotation driving unit for controlling the rotation of the tube clamp. The tube clamp rotation driving unit is used to control the tube clamp to rotate above the connection between the connecting tube and the bag body, or to rotate away from above the connection between the connecting tube and the bag body.

[0009] As an improvement of the bag body sealing detection module of the present invention, the bag pressing mechanism further includes a pressing plate driving unit for driving the horizontal movement of the limiting and stabilizing pressing plate. The limiting and stabilizing pressing plate can be moved above the bag body placement groove or away from above the bag body placement groove under the control of the pressing plate driving unit.

[0010] As an improvement of the bag body sealing detection module of the present invention, a horizontally extending guide rail is provided on the bracket, a slider is provided on the guide rail, the slider can move along the guide rail, and the limiting and stabilizing pressing plate is arranged on the slider.

[0011] As an improvement of the bag body sealing detection module of the present invention, it further includes a printing mechanism for printing marks on the surface of the medicine bag.

[0012] The present invention also provides a bag body sealing detection device, including: a frame; a bag body sealing detection module provided on the frame, the bag body sealing detection module being the aforementioned bag body sealing detection module; a tester corresponding to the bag body sealing detection module, the tester displaying the detection data of the bag body sealing detection module; and a touch operation screen connected to the bag body sealing detection module and the tester.

[0013] The present invention also provides a method for detecting the sealing of a bag body using the aforementioned bag body sealing detection module. The bag body has a connecting tube communicating with it. The steps are as follows:

[0014] S1. Place the bag body in the bag body placement groove and fix the connecting tube at the tube body fixing position.

[0015] S2. The sealed inflation joint moves and docks with the connecting pipe, and the limiting and stabilizing pressing plate moves above the bag body;

[0016] S3. The sealed inflation joint inflates the connecting pipe and the bag body;

[0017] S4. When the inflation reaches the set value, the sealed inflation joint stops inflating, the pipe clamp blocks the connection between the bag body and the connecting pipe, and when the inflation stops, the limiting and stabilizing pressing plate contacts the surface of the bag body and presses on the bag body;

[0018] S5. Let it stand for a period of time to make the pressure in the connecting pipe and the bag body reach equilibrium, and record the gas pressure values in the bag body and the connecting pipe when the pressure is balanced;

[0019] S6. Continue to let it stand for a period of time, detect and record the gas pressure values in the bag body and the connecting pipe again, compare the gas pressure values in the bag body recorded twice and the gas pressure values in the connecting pipe respectively. If the differences between the gas pressure values in the bag body recorded twice and the differences between the gas pressure values in the connecting pipe are within the threshold range, it is considered that the bag body has no leakage.

[0020] Optionally, steps S5 and S6 are replaced by S5' and S6':

[0021] S5'. Let it stand for a period of time to make the pressure in the connecting pipe and the bag body reach equilibrium, detect and record the gas pressure value in the connecting pipe when the pressure is balanced, then continue to let it stand for a period of time, detect and record the gas pressure value in the connecting pipe again, compare the gas pressure values in the connecting pipe recorded twice. If the difference between the gas pressure values in the connecting pipe twice is within the threshold range, it is considered that the pump pipe has no leakage and the next test can be carried out;

[0022] S6'. Restore the connection between the pump pipe and the medicine bag, let it stand for a period of time to make the pressure in the connecting pipe and the bag body reach equilibrium, detect and record the gas pressure value in the bag body, then continue to let it stand for a period of time, detect and record the gas pressure value in the bag body again. If the difference between the gas pressure values in the bag body twice is within the threshold range, it is considered that the bag body has no leakage.

[0023] As can be seen from the above technical solutions, the bag body sealing detection module of the present invention integrates the sealing detection of the connecting pipe and the sealing detection of the bag body, and can automatically complete the sealing detection of two components at one time, without separately detecting the sealing of the pump pipe and the medicine bag on different devices, which simplifies the steps and improves the efficiency. Moreover, the inflation mechanism, the pipe pressing mechanism and the pressing plate mechanism can all perform accurate actions without manual participation, reducing the labor intensity, and can also avoid the situation of component damage caused by improper manual operation. In the preferred technical solution, qualified products and unqualified products after detection can also be printed and marked, which is convenient for subsequent packaging processes. The detection device using the bag body sealing detection module of the present invention can also monitor the air pressure of each detection station in real time through a tester to avoid misjudgment.

[0032] The present invention will be described in detail below with reference to the accompanying drawings.

[0033] Taking the airtightness detection of the medicine bag 20 as an example below, the structure of the bag body airtightness detection module will be described. The medicine bag 20 (bag body) has a pump tube 30 (connecting tube) connected thereto. Refer to Figure 1 , Figure 2 and Figure 3 , the bag body airtightness detection module of this embodiment includes a bracket 1, an inflation mechanism 2, a tube pressing mechanism 3 and a bag pressing mechanism 4. A bag body placement groove 1a for placing the medicine bag 20 is provided on the bracket 1, and the inflation mechanism 2, the tube pressing mechanism 3 and the bag pressing mechanism 4 are all provided on the bracket 1. The inflation mechanism 2 is used to dock with the pump tube 30 and inflate the pump tube 30 and the medicine bag 20. The tube pressing mechanism 3 is used to block the connection between the pump tube 30 and the medicine bag 20, so that the pump tube 30 and the medicine bag 20 are two independent individuals, and thus the airtightness of the pump tube 30 and the medicine bag 20 can be detected. The bag pressing mechanism 4 is used to press on the surface of the medicine bag 20 to balance the pressure after inflation of the medicine bag 20 and limit the expansion of the medicine bag during inflation. As a preferred embodiment of the present invention, a printing mechanism 5 is further provided on the bracket 1, and the printing mechanism 5 is used to print qualified or unqualified marks on the surface of the medicine bag 20. For the convenience of fixing the medicine bag, preferably, a medicine bag bracket fixing part 1b is further provided on the bracket 1 in this embodiment. During detection, the medicine bag 20 is placed in the bag body placement groove 1a, and the medicine bag bracket 21 is fixed through the medicine bag bracket fixing part 1b. A first pressure sensor (not shown) is provided in the bag body placement groove 1a, and the first pressure sensor is used to detect the gas pressure in the medicine bag. In this embodiment, the first pressure sensor is arranged at the bottom of the bag body placement groove 1a, and the airtightness of the medicine bag is detected by detecting the gas pressure in the medicine bag.

[0034] As Figure 4 and Figure 5As shown in the figure, the inflation mechanism 2 of this embodiment includes a sealed inflation joint 2-1, a joint driving unit 2-2, and a pipe body fixing position 2-3. The sealed inflation joint 2-1 is connected to a gas source (not shown) and is used to be hermetically docked with the pump pipe 30 to inflate the pump pipe 30 and the medicine bag 20. A second pressure sensor (not shown), such as a pressure gauge, is provided at the sealed inflation joint 2-1. The second pressure sensor is used to detect the gas pressure in the pump pipe 30, and the tightness of the pump pipe is detected by detecting the gas pressure in the pump pipe. The first and second pressure sensors transmit data to the PLC control system through signal lines. The pipe body fixing position 2-3 is arranged opposite to the sealed inflation joint 2-1, and the pipe body fixing position 2-3 is used to fix the pump pipe 30 to facilitate the accurate docking of the sealed inflation joint 2-1 and the pump pipe 30. The joint driving unit 2-2 is used to control the movement of the sealed inflation joint 2-1 to make the sealed inflation joint 2-1 dock with or separate from the pump pipe 30. The joint driving unit 2-2 of this embodiment adopts a cylinder, and the cylinder controls a sliding seat 2-4 to slide horizontally. The sealed inflation joint 2-1 is arranged on the sliding seat 2-4. As Figure 4 shown, before the detection, the sealed inflation joint 2-1 is not in contact with the pump pipe 30. During the detection, the joint driving unit 2-2 controls the sealed inflation joint 2-1 to move towards the pump pipe 30 and press on the end of the pump pipe 30 to be hermetically docked with the pump pipe 30, as Figure 5 shown, while ensuring the tightness of the end of the pump pipe 30, the pump pipe 30 and the medicine bag 20 are inflated.

[0035] The pipe pressing mechanism 3 of this embodiment includes a pipe clamp 3-1 and a pipe clamp driving unit 3-2. The pipe pressing mechanism 3 is arranged at the connection of the pump pipe 30 and the medicine bag 20. The pipe clamp 3-1 of this embodiment is used to press the connection of the pump pipe 30 and the medicine bag 20, block the connection between the pump pipe 30 and the medicine bag 20, and keep the pump pipe 30 and the medicine bag 20 non-connected to each other during detection, so that the sealing performance of the pump pipe 30 can be detected. The pipe clamp driving unit 3-2 of this embodiment is used to drive the pipe clamp 3-1 to descend and rise. When the pipe clamp 3-1 descends, it presses between the pump pipe 30 and the medicine bag 20, thereby blocking the connection between the pump pipe 30 and the medicine bag 20. When it rises, the connection between the pump pipe 30 and the medicine bag 20 resumes. The pipe clamp 3-1 of this embodiment needs to cooperate with a planar component (not labeled) to press the connection between the pump pipe 30 and the medicine bag 20. However, in other embodiments, the pipe clamp 3-1 can also be in the form of a clip. The pipe clamp driving unit 3-2 is used to control the action of the pipe clamp 3-1 to block or resume the connection between the pump pipe 30 and the medicine bag 20. For the convenience of installing the medicine bag and the pump pipe and to avoid component interference, preferably, this embodiment further includes a pipe clamp rotation driving unit 3-3. The pipe clamp rotation driving unit 3-3 is used to rotate the pipe clamp 3-1 above the connection between the pump pipe 30 and the medicine bag 20 during detection, and rotate the pipe clamp 3-1 away from above the connection between the pump pipe 30 and the medicine bag 20 when not detecting. Both the pipe clamp downward pressing driving unit 3-2 and the pipe clamp rotation driving unit 3-3 can adopt air cylinders.

[0036] The medicine bag pressing mechanism 4 of this embodiment includes a limiting and stabilizing pressing plate 4-1 and a pressing plate driving unit 4-2. The limiting and stabilizing pressing plate 4-1 is movably arranged on the bracket 1. The limiting and stabilizing pressing plate 4-1 can be moved above or away from above the bag placing groove 1a under the control of the pressing plate driving unit 4-2. The function of the limiting and stabilizing pressing plate 4-1 is, on the one hand, to press on the medicine bag to limit the expansion space of the medicine bag when inflated, and on the other hand, to keep the internal pressure of the medicine bag balanced and stable by pressing the medicine bag tightly. In this embodiment, a horizontally extending guide rail 1c is arranged on the bracket 1, a slider 4-3 is arranged on the guide rail 1c, the slider 4-3 can move along the guide rail 1c, and the limiting and stabilizing pressing plate 4-1 is arranged on the slider 4-3. The pressing plate driving unit 4-2 controls the movement of the limiting and stabilizing pressing plate 4-1 by controlling the movement of the slider 4-3. The pressing plate driving unit 4-2 of this embodiment adopts an air cylinder.

[0037] The following combines Figures 1 to 3 , and further describes the sealing detection method of the bag body sealing detection module of this embodiment. The steps of the sealing detection method are as follows:

[0038] S1. As Figure 1As shown, when detecting, the medicine bag 20 is placed in the bag body placement groove 1a, and the pump tube 30 is fixed on the tube body fixing position 2-3. At this time, the tube clamp 3-1 is in the initial position, that is, it has not yet rotated above the connection between the pump tube 30 and the medicine bag 20, and the limit and stable pressing plate 4-1 is also in the initial position, that is, it has not yet moved above the medicine bag 20;

[0039] S2. After the medicine bag 20 and the pump tube 30 are installed and fixed, as Figure 2 shown, the joint driving unit 2-2 controls the movement of the sealing and inflating joint 2-1 to dock with the end of the pump tube 30. Then, as Figure 3 shown, the pressing plate driving unit 4-2 controls the limit and stable pressing plate 4-1 to move above the medicine bag 20;

[0040] S3. The sealing and inflating joint 2-1 starts to inflate the pump tube 30 and the medicine bag 20. Since the limit and stable pressing plate 4-1 is above the medicine bag 20, the limit and stable pressing plate 4-1 can limit the expansion space of the medicine bag 20 and ensure the stability of the inflation pressure;

[0041] S4. When the air pressure value in the medicine bag 20 reaches the set value, stop inflating. When the inflation is completed, the limit and stable pressing plate 4-1 contacts the surface of the medicine bag 20 and presses on the medicine bag 20. The tube clamp 3-1 rotates above the connection between the medicine bag 20 and the pump tube 30 and moves downward to press on the connection between the medicine bag 20 and the pump tube 30, so that the medicine bag 20 and the pump tube 30 cannot communicate with each other;

[0042] S5. Let it stand for a period of time to make the pressures in the pump tube 30 and the medicine bag 20 reach pressure balance. The first pressure sensor and the second pressure sensor respectively detect the gas pressure values in the medicine bag 20 and the pump tube 30, and record the gas pressure values in the medicine bag 20 and the pump tube 30 at the time of pressure balance;

[0043] S6. Continue to let it stand for a period of time, and detect and record the gas pressure values in the medicine bag 20 and the pump tube 30 again. Compare the difference between the two recorded gas pressure values in the medicine bag and the difference between the gas pressure values in the pump tube respectively. If the differences between the two recorded gas pressure values in the medicine bag and the differences between the gas pressure values in the pump tube are both within the threshold range, it is considered that there is no leakage and it is a qualified product. The printing mechanism 5 prints a qualified mark on the surface of the medicine bag. The value of the threshold is an empirical value and can be set accordingly according to the product quality requirements. The standing time is set according to the detection requirements. This embodiment can detect the sealing performance of the pump tube and the bag body at the same time, with high efficiency.

[0044] As an optional implementation manner of the present invention, steps S5 and S6 can be replaced by the following steps S5' and S6':

[0045] S5'. Keep it static for a period of time until the pressure in the pump tube 30 and the medicine bag 20 reaches equilibrium. Then, the second pressure sensor detects and records the gas pressure value in the pump tube 30. After that, keep it static for another period of time. The second pressure sensor detects and records the gas pressure value in the pump tube 30 again. Compare the two recorded gas pressure values in the pump tube. If the difference between the two recorded gas pressure values in the pump tube is within the threshold range, it is considered that there is no leakage in the pump tube, and the next test can be carried out;

[0046] S6'. Control the pipe clamp 3-1 to release the blockage of the connection between the pump tube 30 and the medicine bag 20, so that the pump tube 30 and the medicine bag 20 are restored to communication. Keep it static for a period of time until the pressure in the medicine bag 20 reaches equilibrium. The first pressure sensor detects and records the gas pressure value in the medicine bag 20. Then, keep it static for another period of time. The first pressure sensor detects and records the gas pressure value in the medicine bag 20 again. Compare the two recorded gas pressure values in the medicine bag. If the difference between the two recorded gas pressure values in the medicine bag is within the threshold range, it is considered that there is no leakage in the medicine bag, and it is a qualified product. This detection method can also detect whether the connection between the pump tube and the medicine bag is well sealed, and the detection is more comprehensive. Figure 6 It is a structural schematic diagram of the bag body seal detection device. The bag body seal detection device of this embodiment includes a frame 100, several groups of bag body seal detection modules 101 arranged on the frame 100, a tester 102 corresponding to the bag body seal detection module 101, and a touch operation screen 103. Each bag body seal detection module 101 is connected to a tester 102. The tester 102 can display detection data such as pressure values in real time. The touch operation screen 103 is connected to the bag body seal detection module 101 and the tester for human-computer interaction. The number of bag body seal detection modules 101 can be set accordingly according to production requirements. This embodiment is a 5-station device, and a total of 5 groups of bag body seal detection modules 101 are set.

[0047] The bag body seal detection device of the present invention can control each mechanism to automatically coordinate actions according to the set parameters through the PLC control system, integrating the two steps of separately detecting the tightness of the pump tube and the medicine bag together, and simultaneously completing the airtightness detection of the pump tube and the medicine bag. Compared with the manual detection method, it can reduce the error rate, avoid damage to the parts to be tested caused by improper operation, reduce the labor intensity, and improve the overall efficiency. At the same time, a precision detector is used for sampling, judging, recording and outputting test data, and the detection data is displayed in real time, which can ensure the consistency, accuracy and timeliness of the product detection results. In the preferred technical solution, a touch screen with communication function is used to control the PLC control system to work, realizing human-machine interface interaction, facilitating the selection of various models, the modification of various parameters, data recording and function upgrade, and improving the flexibility of the device.

[0048] Certainly, the technical concept of the present invention is not limited to the above embodiments. Many different specific solutions can also be obtained according to the concept of the present invention. For example, in addition to using a cylinder, the driving unit can also use conventional mechanical driving structures such as motors, electric rods, and servo mechanisms. The sliding connection structure between components can adopt the structure of a guide rail + slider, or can also adopt the structure of a chute + slider. The present invention can be used not only for the sealing detection of medicine bags used in electronic micropumps, but also for the sealing detection of other bags such as food bags and packaging bags with connecting pipes. Such changes and equivalent transformations should all be included within the scope of the present invention.
