Bubble detection device

Abstract

The invention relates to a bubble detection device which comprises a transmitting terminal and a receiving terminal which are respectively arranged at two sides of a transfusion pipeline, wherein the transmitting terminal comprises an opening and closing gate, a transmitting probe and a first piezoelectric wafer; the opening and closing gate is provided with four bumps; a bottom plate is fixed at the left sides of the bumps through screws, and the middle part of the bottom plate is provided with the transmitting probe; a trough is arranged on the transmitting probe which is internally provided with the first piezoelectric wafer; the right side of the first piezoelectric wafer is provided with a spring which props against the opening and closing gate; the receiving terminal comprises a receiving probe corresponding to the transmitting probe and a second piezoelectric wafer; and the receiving probe is internally provided with the second piezoelectric wafer and is respectively fixed on a mounting bracket and a panel. The bubble detection device provided by the invention has the beneficial effects of solving the problem of the installation reliability of most commercial transfusion pipelines which are made of different materials and have different sizes in an ultrasonic conduction path and ensuring that an ultrasonic bubble detection mode is more reliable and easy to use.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a bubble detection device. Background technique [0002] During the clinical application of the infusion line to treat patients, it is necessary to accurately and effectively detect the air bubbles in the infusion line to ensure the safety of the patient's life. At present, the air bubble detection methods of mainstream infusion pumps and infusion set products in the market are all ultrasonic detection methods, and the structure is to clamp or support the infusion pipeline on both sides to ensure the ultrasonic conduction path. However, due to the large number of existing infusion set manufacturers, The specifications and materials of the infusion sets used are different, and the matching distance between the pre-set air bubble probes is fixed, which cannot be specially matched according to the differences in the pipelines. As a result, the pipelines of the infusion sets cannot b...

At present, the air bubble detection methods of mainstream infusion pumps and infusion set products in the market are all ultrasonic detection methods, and the structure is to clamp or support the infusion pipeline on both sides to ensure the ultrasonic conduction path. However, due to the large number of existing infusion set manufacturers, The specifications and materials of the infusion sets used are different, and the matching distance between the pre-set air bubble probes is fixed, which cannot be specially matched according to the differences in the pipelines. As a result, the pipelines of the infusion sets cannot be reliably compacted. False air bubbles are generated due to fit gaps on the tube or additional adjuvants such as petroleum jelly are required to eliminate the tubing fit gap
