Embodiment 1

[0026] Such as figure 1 , image 3 Shown, a kind of infusion set airtightness / permeability automatic detection device is characterized in that it comprises an air source and an air intake line connected with the air source, an air source cleaning processor is arranged on the air intake line, and the air source The air intake pipeline behind the cleaner is provided with a pressure regulator, a pressure and flow discriminator in sequence, and an interface for connecting the input end of the infusion set is provided at the end of the air intake pipeline, and a pressure valve is provided on the interface, and the pressure valve’s The leading end 1 is connected with the air inlet pipeline, and the air outlet end is provided with a sealing connection nozzle 2 for connecting the measured piece. There is a photoelectric switch next to the interface, and an air leakage detection chamber 3 is provided on the outside of the sealing connection nozzle 2, and a sealing socket 6 coaxial wit...

Embodiment 2

[0035] Such as figure 2 As shown, the warning device includes a buzzer and / or an indicator light, and the indicator lights include a low flow indicator light, a high flow indicator light, a seal leakage indicator light and a valve blockage indicator light. When the gas flow rate is too low, the controller controls the low flow indicator light to be on, indicating that the test piece has a blockage problem; otherwise, the high flow indicator light is on, which means that the test piece has a gas leakage problem. When there is any fault or blockage or air leakage problem, the buzzer will sound, and it can emit sounds of different lengths and frequencies according to different problems. If there is a problem with the seal between the sealing connection nozzle and the test piece, the gas flows out, and all or most of it flows out from the gas outlet pipe. If there is an air leak between the seals, it will send a signal to the controller, and the controller will warn the operator...

Abstract

The invention relates to a gas tightness / air permeability automatic detecting device for an infusion apparatus and a control method thereof. The gas tightness / air permeability automatic detecting device comprises an air source and an air inlet pipeline connected with the air source. An air source cleaning processor is arranged on the air inlet pipeline; a pressure adjuster, and a pressure and flow judger are sequentially arranged on the air inlet pipeline in back of an air source cleaner; a port for connecting the input end of the infusion apparatus is arranged at the tail end of the air inlet pipeline; a position sensor is arranged at a position beside the port; the signal output end of the position sensor is connected with a controller; and the controller is respectively connected with the pressure and flow judger and an alarming device through a signal circuit. According to the invention, the gas tightness / air permeability automatic detecting device and the detecting method utilizing the detecting device, both of which have the advantages of high automation, convenience in detection and system self-detecting function, are realized.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for an infusion set. Background technique [0002] The full name of sterile devices is disposable sterile medical devices, which refer to medical devices that are sterile, non-pyrogenic, qualified after inspection, and can be used directly for one-time use within the validity period. Disposable infusion sets are sterile instruments. [0003] The automation equipment industry of sterile medical devices has developed vigorously in recent years, but the degree of automation of sterile medical device companies is still very low at this stage, and there is still a lot of room for improvement in the degree of automation. For example, the production and assembly process of disposable infusion sets is basically still a manual operation. The main reason is that the new products to be assembled are flexible plastic parts, which are more difficult to realize automatic assembly than ...
