Description

Technical Field

[0001] The present invention relates to the technical field of endoscope biopsy valve detection devices, and in particular to a sealing detection device for an endoscope biopsy valve. Background Art

[0002] The biopsy valve is a device installed on an endoscope and used to allow endoscopic instruments to enter and exit the endoscope and to prevent negative pressure leakage in the endoscope. During the long-term use of the biopsy valve, the one-way valve flap in the biopsy valve will be worn due to the frequent entry and exit of endoscopic instruments, which will affect the sealing of the biopsy valve. When the sealing of the biopsy valve decreases, the negative pressure effect of the endoscope will be weakened, and finally the suction effect of the endoscope will be weakened. At present, the judgment of the sealing of the biopsy valve depends on the experience of medical staff, that is, there will be a situation where the biopsy valve is discarded even though the sealing is acceptable, which will cause a waste of the biopsy valve; in addition, the current detection of the sealing of the biopsy valve is completely dependent on manual judgment, which has the disadvantage of low efficiency in the detection of the sealing of the biopsy valve.

[0020] A groove 13 for partially embedding the biopsy valve is provided on the upper end surface of the box body 1, and the light-transmitting hole 12 is provided at the bottom of the groove 13. After the biopsy valve is embedded in the groove 13, the one-way valve in the biopsy valve and the light-transmitting hole 12 are arranged correspondingly in the vertical direction; through the setting of the groove, when the sealing of the biopsy valve is tested, the biopsy valve can be partially embedded in the groove, so that the positioning of the biopsy valve can be achieved, and the one-way valve in the biopsy valve can be conveniently aligned with the light-transmitting hole.

[0021] An air suction port 14 connected to the cavity 11 is provided on the side wall of the box body 1, and the air suction port 14 is used to be connected to a negative pressure device; through the setting of the air suction port, when the air suction port is connected to the negative pressure device and when the negative pressure device is working, a negative pressure can be formed in the inner cavity of the box body.

After the silicon photoelectric panel is irradiated by the laser, the silicon photoelectric panel can output a voltage and display the voltage value through a digital voltmeter. In the above-mentioned detection process, if the voltage value displayed by the digital voltmeter is lower than a certain value, it means that the light transmittance of the one-way valve structure in the biopsy valve is poor, which means that the sealing performance of the biopsy valve is good (the biopsy valve can continue to be used). If the digital voltmeter shows When the voltage value displayed on the digital voltmeter is higher than a certain value, it means that the light transmittance of the one-way valve structure in the biopsy valve is better, which means that the sealing of the biopsy valve is poor (the biopsy valve needs to be replaced); for example, when the voltage value displayed on the digital voltmeter is less than 50 millivolts, it means that the one-way valve structure in the biopsy valve is not easy for the laser to pass through, which means that the sealing of the biopsy valve is better (the biopsy valve can continue to be used); when the voltage value displayed on the digital voltmeter is greater than 50 millivolts, it means that the one-way valve structure in the biopsy valve is easy for the laser to pass through, which means that the sealing of the biopsy valve is poor (the biopsy valve needs to be replaced); after the above process, the present invention can realize the detection of the sealing of the biopsy valve, which can avoid the situation where the biopsy valve is discarded even though it has acceptable sealing, thereby avoiding the waste of the biopsy valve.
