Description

Technical Field

[0001] The utility model relates to the technical field of glove detectors, in particular to a wireless glove integrity detector. Background Art

[0002] The environment and equipment requirements for drug production are becoming increasingly higher. The pharmaceutical isolator is a highly airtight device that can effectively prevent contamination by pollutants and microorganisms during the drug production process while protecting the health of production personnel. The gloves in the pharmaceutical isolator are indispensable tools in the drug production process, and their airtightness directly affects the quality and safety of the drug.

[0003] Testing the tightness of gloves is a crucial part of the pharmaceutical isolator production process. Existing wireless glove integrity testers mainly determine the tightness of gloves by monitoring the pressure difference inside the gloves. When a glove leaks, the pressure difference inside the glove will change. The leak detector can determine whether the glove is leaking by monitoring this change. The existing detection method does not consider the influence of temperature. If the temperature changes during the monitoring process, it will affect the accuracy of the judgment, resulting in deviations in the glove tightness test results. Utility Model Content

[0032] The panel housing 1 is respectively mounted with a control screen 5, a control button 6 and a control board 19, and the control screen 5 is electrically connected to the control button 6 and the control board 19;

[0033] The temperature sensor 10 and the differential pressure transmitter 20 are both electrically connected to the control board 19. The temperature sensor 10 is used to detect the internal temperature of the glove, and the differential pressure transmitter 20 is used to detect the internal pressure differential of the glove. During the pressure-maintaining process after the glove is inflated, the control board 19 calculates the change in the internal pressure differential of the glove based on the detection results provided by the temperature sensor 10 and the differential pressure transmitter 20, and thus determines whether the glove integrity test has passed.

[0034] The inflation component includes an airtight inflation pump 16, an electromagnetic valve 24 and a pressure transmitter 25. The airtight inflation pump 16, the electromagnetic valve 24 and the pressure transmitter 25 are all installed inside the instrument installation shell 2. The airtight inflation pump 16, the electromagnetic valve 24 and the pressure transmitter 25 are respectively connected to the inflation sealing ring 4 through closed pipelines. The airtight inflation pump 16 and the electromagnetic valve 24 are both electrically connected to the control board 19.

[0035] A power supply component is installed on the detection end mounting member 3, and the power supply component includes a battery 23, a charging port 14 and a power button 15. The battery 23 is installed inside the instrument mounting shell 2, and the charging port 14 and the power button 15 are both arranged on the surface of the instrument mounting shell 2, and the charging port 14 and the power button 15 are electrically connected to the battery 23 respectively, and the battery 23 supplies power to the control board 19 and the control screen 5 respectively.

[0036] A plurality of fixing bolts 11 are provided on the detection end mounting member 3 , and the detection end mounting member 3 is mounted on the bottom of the instrument mounting housing 2 through the fixing bolts 11 .

[0037] The bottom of the instrument mounting housing 2 is provided with a grid hole 7. The function of the grid hole 7 is to maintain the stability of the pressure difference and temperature inside and outside the glove wireless integrity tester, so as to make the detection value more accurate.

[0038] A speaker 18 is installed inside the instrument installation housing 2, and the speaker 18 reports the result of the glove integrity test in voice.

[0039] The surface of the instrument mounting shell 2 is respectively installed with a mesh hole 12 and a program debugging hole 13.

[0040] The device further includes: an RFID module 22 and an antenna module 21. The antenna module 21 is welded to the control board 19 and is used to realize wireless communication between the glove wireless integrity tester and external devices. The RFID module 22 is installed inside the instrument mounting housing 2 and is used to read the label information on the glove flange. The RFID module 22 and the wireless antenna module 21 are respectively installed inside the instrument mounting housing 2. The RFID module 22 is used to read the label information on the glove flange to be tested. If the RFID module 22 does not read the label information on the glove flange, the inflatable sealing ring 4 cannot be inflated. The function of the wireless antenna module 21 is to communicate with the glove wireless integrity tester and other main equipment, such as the host of the pharmaceutical isolator. In this way, the glove wireless integrity tester can perform glove integrity testing independently or meet the needs of glove integrity testing online with the host equipment. The test report and data can be integrated into the host equipment.

[0041] The detection end mounting member 3 includes a bottom wall and an annular sidewall integrally connected to the bottom wall. The annular sidewall is provided with a mounting groove, into which the inflation seal ring 4 is mounted. The glove pressure differential detection hole 8, the glove inflation hole 9, and the temperature sensor 10 are all provided on the bottom wall. Preferably, the temperature sensor 10 is located between the glove pressure differential detection hole 8 and the glove inflation hole 9.

[0042] In this embodiment, the detection end mounting member 3 has a hollow portion defined by an annular side wall. Due to the hollow portion, the detection end mounting member 3 is light in weight. The detection end mounting member 3 is detachably connected to the instrument mounting housing 2, and its light weight makes it easier to disassemble.

[0043] In other embodiments, the detection end mounting member 3 can also be designed as a flat plate structure with uniform thickness, and the flat plate structure is provided with a glove pressure difference detection hole 8 and a glove inflation hole 9 along its thickness direction, and a mounting groove for installing the inflation sealing ring 4 is provided on the side wall of the flat plate structure.

[0044] In a specific embodiment, the battery 23 has a built-in power detection module and a communication interface integrated on the battery 23. The control board 19 directly reads the power data of the battery 23 through the communication interface, which can improve the accuracy and reliability of the power display of the battery 23 and avoid sudden power failure of the device due to inaccurate power display during use;

[0045] In this embodiment, the detection accuracy of the differential pressure transmitter 20 is higher than or equal to ±0.25% FS to meet the demand for high-precision detection.

[0046] In a specific embodiment, the inflatable sealing ring 4 is made of an elastic material. The elastic material can be an existing material, for example, silicone rubber. It not only has better sealing performance, but also can be deflated by itself after the test is completed without the need for a vacuum pump, thereby facilitating the separation of the glove flange and the detection end mounting piece 3 and improving the convenience of operation.

[0047] During glove integrity testing, the power button 15 is pressed, and the battery 23 supplies power to the control panel 19 and control screen 5. The leak detection end mounting member 3 is fixed to the mounting housing 2 via the fixing bolts 11. One end of the detection end mounting member 3 is docked with the flange of the glove to be tested. The detection end mounting member 3 can be manufactured to match the size and shape of the glove flange to be tested. Simply replacing the detection end mounting member 3 with a matching size and shape can meet the need of testing different glove flanges with a single leak detector. The RFID module 22 detects the label on the glove flange to be tested. At this time, the control button 6 is pressed, and the airtight air pump 16 is controlled by the control panel 19 to inflate the inflatable seal ring 4. There is a program interlock setting here. If the RFID module 22 does not detect the label on the flange, the airtight air pump 16 cannot be inflated. During the inflation process of the inflatable seal ring 4, the pressure transmitter 25 continuously detects the inflation pressure. When the inflation pressure reaches the sealing pressure of 0.2 MPa, the airtight air pump 16 stops inflating and maintains the airtight state. At this time, the inflatable seal ring 4 and the glove flange to be tested are sealed all around. Afterwards, the glove integrity test is started by operating the control panel 5. The glove inflation pump 17 starts to inflate the glove through the glove inflation hole 9. During the glove inflation process, the pressure differential transmitter 20 is connected to the glove pressure differential detection hole 8 through a sealed pipeline to detect the internal pressure differential of the glove in real time. When the pressure differential transmitter 20 detects that the internal pressure differential of the glove reaches the set value, the glove inflation pump 17 stops inflating the glove and the glove enters the pressure holding state. During the pressure holding process, the temperature sensor 10 detects the internal temperature of the glove throughout the entire process. The detection result of the temperature sensor 10 is used to determine whether the glove integrity test is qualified or not. ΔP=P1-P2*(T1 / T 2), where ΔP is the pressure differential change, P1 is the absolute pressure differential at the beginning of the glove pressure holding period, P2 is the absolute pressure differential at the end of the glove pressure holding period, T1 is the absolute temperature inside the glove at the beginning of the glove pressure holding period, and T2 is the absolute temperature inside the glove at the end of the glove pressure holding period. When the set pressure holding period expires, if the pressure differential change ΔP is higher than the set value, the glove integrity test is considered to have passed. The pass information is displayed on the control screen 5, and the speaker 18 simultaneously reports the test status. After the glove integrity test is completed, the control button 6 is pressed, and the control panel 19 controls the solenoid valve 24 to open, defluffing the inflatable sealing ring 4 and the glove simultaneously. The glove flange can then be removed.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
