In addition, the technical features involved in the embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.

A hose is a tubular product for transporting water, oil, chemicals of low concentration and other liquids, which has been widely used in many fields of food, hygiene, medical treatment, industry and agriculture. The hose products can be divided into various types according to different materials, such as stainless steel hoses, metal hoses, corrugated hoses, rubber hoses, plastic hoses and the like; among them, the plastic tube is most widely used, and as a typical example of the plastic tube, an infusion tube (also called a disposable iv set) is often used to establish a passage between a human vein and a medical fluid. Regardless of the type of hose product, stability in transferring liquid and no leakage of the transferred liquid are critical, and therefore, airtightness of the hose product has become a concern for each manufacturer.

In the correlation technique, the airtightness detection device for the hose product is only provided with one detection position for the hose product of each specification, so that batch detection of the hose product of the same specification cannot be realized, and further the efficiency in batch detection is extremely low.
