Abstract

The invention discloses a medical instrument, belongs to the technical field of appliances, and particularly relates to an air detector for disposable venous transfusion needles. The air detector for the disposable venous transfusion needles comprises an upper module and a lower module; an isolation film is sandwiched between the upper module and the lower module; an air drum is arranged in the lower module and is connected with an air inlet valve by an air inlet pipe, and the air inlet valve is connected with an air inlet source pipeline; and a pressurizing bag is arranged in the upper module and is connected with a detecting air pipe, and a multi-head connector is connected with the detecting air pipe, is connected with a pressure gauge by an air outlet pipe and is connected with a product detecting joint. The air detector has the advantages that the test pressure can meet specified requirements assuredly, products are prevented from being damaged by excessively high pressure, and secondary pollution of the products can be reduced.

Description

technical field [0001] The medical device of the invention belongs to the technical field of appliances, and in particular relates to a gas detector for disposable intravenous infusion needles. Background technique [0002] Disposable intravenous infusion needles are commonly used infusion equipment in hospitals. Disposable intravenous infusions have certain requirements for their tightness and smoothness of pipelines and needles. And at present, when producing disposable use intravenous infusion needle, all adopt manual operation for the general method of its detection. Moreover, when checking its airtightness and checking whether the intravenous infusion needle pipeline and the needle are unimpeded, the detection test is carried out separately. As a result, the entire detection process takes a long time, and two processes need to be performed, which is troublesome for the entire detection process and is prone to errors. Moreover, it is easy to cause damage or secondary p...
