Problems solved by technology

At present, whether these parts are leaking is done manually, resulting in extremely low detection efficiency
Moreover, manual operation is easy to cause the infusion set to be infected with germs, resulting in unqualified product hygiene requirements; in order to overcome this defect, it is often necessary to strictly disinfect the production workers, and at the same time operate in a huge aseptic purification workshop, which requires huge consumption Energy and production space, high inspection costs

Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, an air leakage detection device between a needle base of an infusion set and an infusion tube includes a bracket 6, on which a moving mechanism for sealing the test gas assembly and the needle base 24 is installed, and the bracket 6 is also installed with an air delivery mechanism that provides compressed air for the air test assembly, and an air leakage judging mechanism is connected to the air delivery mechanism.

[0019] The moving mechanism includes a guide shaft 5 fixed on the bracket 6, and two linear bearings 7 that can move left and right along the guide shaft 5 are mounted on the guide shaft 5. The cylinder main board 4 is fixed on the linear bearing 7, and the cylinder main board 4 is driven by the driving cylinder 19 to move left and right. Fixed with the cylinder push block 20, the purpose of this design makes the structure more compact. The reason why two linear bearings 7 are adopted is to make the cylinder main b...

Abstract

The invention relates to a device for detecting air leakage between a needle seat and an infusion tube of an infusion set. The device is characterized by comprising a bracket, wherein a travel mechanism used for splicing a gas testing assembly and the needle seat in a sealed way is arranged on the bracket, a gas transmission mechanism used for providing compressed air for the gas testing assembly is further arranged on the bracket, and the gas transmission mechanism is connected with an air leakage judgment mechanism. According to the device for detecting air leakage between the needle seat and the infusion tube of the infusion set, provided by the invention, the automation of the air leakage detection of the needle seat and the infusion tube is achieved; after the automatic detection substitutes for manual operation, the detection efficiency is greatly improved, and the infusion set is protected from being polluted by germs, so that the cleanliness of the infusion set is ensured; and with no need for huge energy consumption and large production spaces, the detection cost is greatly lowered.

Description

technical field [0001] The invention relates to an air leakage detection device between a needle seat of an infusion set and an infusion tube, and belongs to the technical field of medical machinery. Background technique [0002] With the improvement of social living standards, transfusion is more widely used in various clinical cases as an important treatment method. The present whole infusion set usually includes a drip funnel assembly, an infusion tube, a puncture needle and a needle seat for installing the puncture needle. The dripping funnel assembly includes the dripping funnel and the two-way / three-way connecting piece, and the infusion tube connects the dropping funnel assembly and the needle seat together. In order to prevent the occurrence of safety accidents such as leakage, quite high requirements are put forward for the sealing performance of the infusion set. The parts of the entire infusion set that are prone to leakage include the junction of the drip funne...
