Problems solved by technology

However, the current connection fastness detection is mainly done manually, that is, grasp the two connecting parts with two hands and apply a certain force. If it falls off, it is a waste product, otherwise it is a qualified product.
Disadvantages of manual operation: first, it is easy to bring germs into the infusion tube; The product is tested and passed

Abstract

The invention relates to a vein needle catheter pulling force detection device, which comprises a rack assembly. A placement mechanism for placing a vein needle catheter is arranged on the rack assembly; the top of the rack assembly is provided with a positioning device for positioning the vein needle catheter; the position of the positioning device is corresponding to that of the placement mechanism; the rack assembly is also provided with a vein needle catheter clipping device; and the clipping device is connected with a pulling force testing device for detecting whether the pulling force of the vein needle catheter is qualified. By adopting the above technical scheme, detection on the pulling force between a needle seat and an infusion pipe is automatic; and as automatic detection replaces manual operation, the detection efficiency is greatly improved, products can be protected from being polluted by germs, and the cleanliness of products is ensured.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for medical device production, and in particular relates to a device for detecting tension of 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 pass a tensile test before leaving the factory; at present, with the improvement of social living standards, infusion as an important treatment method is more w...
