Vein needle catheter ventilation detection apparatus

Abstract

The invention relates to a vein needle catheter ventilation detection apparatus which comprises a machine rack, wherein a clamping mechanism used for clamping a vein needle catheter hard seat and a clamping and pressing mechanism used for clamping a vein needle catheter needle stand are mounted on a support rack, positions of the clamping mechanism and the clamping and pressing mechanism respectively correspond to those of the vein needle catheter hard seat and the vein needle catheter needle stand, and the support rack is provided with a ventilation assembly which is matched with the hard seat. Via adoption of the technical solution, the automatic detection of gas leak between the needle stand and an infusion tube can be realized, detection efficiency can be improved greatly, product cleanliness can be ensured, great consumption of energy and great occupation of production space can be prevented, detection cost can be greatly lowered, the clamping mechanism adopts a lower clamping arm plate and an upper clamping arm plate that are matched with each other in structure, convenience of catheter clamping operation can be realized, catheter connection stability can be increased, simple and compact installation can be realized, and accuracy can be realized when the upper clamping arm plate and the lower clamping arm plate are used for a clamping purpose; full preparation is made for subsequent leak detection, blockage detection and ventilation detection; requirements for accuracy can be met, and detection efficiency and production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for medical device production, and in particular relates to a ventilation detection device for a venous needle catheter. Background technique [0002] An infusion set is a disposable medical consumable mainly used for intravenous infusion, which is usually composed of an intravenous needle, a liquid medicine filter, a short infusion tube, a flow rate regulator, a long infusion tube, a drip funnel, an infusion tube, an air intake tube, The air filter is composed of a bottle inserting needle and a sheath connection, and the bottle inserting needle has a piercing part, a connecting end and an air inlet part connected with the air filter. [0003] In order to ensure the normal operation of the infusion set, the infusion set needs to undergo a sealing test before leaving the factory. At present, the testing of the airtightness of the infusion set is generally to inflate the infusion set, s...

Problems solved by technology

[0004] The "software leak detection device" disclosed in Chinese Patent No. 200920251291.6 includes a box body, a locking mechanism for the tested piece and an air pressure balance detection system. Detect whether there is leakage in the test piece by changing the air pressure in the standard air tank and the tube of the test piece and observing whether there are bubbles in the water in the cylinder. Whether there are bubbles in the cylinder needs to be observed by someone all the time. When there are bubbles, the air leakage of the test piece cannot be accurately judged. Whether the degree is within the range allowed by the standard, when the air bubbles are small, it is not easy to be found, and when the test piece is blocked, no air bubbles can be generated in the real cylinder, thus reducing the test quality of the test piece

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
