Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The following embodiments are only explanatory and do not constitute a limitation of the present invention. All modifications or variations made without departing from the spirit of the present invention belong to protection scope of the present invention.

[0026] like figure 1 As shown, the gas leakage detection device of the embodiment of the present invention includes a sealing part 1 , a clamping part 2 and an air delivery part 3 . Among them, the sealing part 1 is used to complete the sealing of the ventilating end of the infusion tube needle, the clamping part 2 is used to tighten and fix the infusion tube to ensure that the position of the infusion tube is fixed on the test workbench during the entire test process, and the gas delivery part 3 is used to fix the infusion tube. The other end of the infusion tube is pressurized wi...

Abstract

The invention discloses an air leakage detection device. The air leakage detection device is arranged on a working table, is used for achieving air leakage detection to an infusion tube and is characterized by comprising a sealed part (1), a clamping part (2) and a gas transmission part (3), wherein the sealed part (1) is arranged at one end of the working table and is used for sealing of an aeration end of a needle head of the infusion tube; the clamping part (2) is arranged in the middle of the working table and is used for clamping and fixing the infusion tube to be detected and enabling the position of the infusion tube to be fixed in the process of detection; the gas transmission part (3) is arranged at the other end of the working table and is used for transmitting gas to and pressurize the other end, relative to a pillow, of the infusion tube. After aeration and pressure maintaining for a period of time, the detection whether the infusion tube leaks the gas can be achieved through a pressure change inside a measuring tube. The air leakage detection device is compact in operation, higher in efficiency than manual operation and small in pollution to the infusion tube than the manual operation. A pneumatic control circuit is adopted to pressurize the infusion tube and test the magnitude of pressure, and therefore the possibility of manual misjudgment is reduced, and the operation precision is improved.

Description

technical field [0001] The invention relates to an air leakage detection device for an infusion tube, which belongs to the field of medical equipment production equipment. Background technique [0002] The production process of the disposable infusion tube is to load the material first and put it into the air leakage test device. After the test is completed, the infusion tube is manually wound into a specified form, put into the prepared packaging bag, and then the unified sealing operation is carried out by a special person. , and boxed. [0003] The current air leakage detection of the infusion tube is carried out manually. To detect the air leakage of the infusion tube, put it into the test device manually, manually block one end of the test, ventilate the other end and keep the pressure for 4-5 seconds, and judge the airtightness of the piece manually through the barometer and select it. [0004] The current infusion tube air leakage detection has the following shortco...
