Composite-type safety infusion apparatus

Abstract

The invention provides a composite-type safety infusion apparatus. The infusion apparatus comprises an infusion bottle, a dripping bucket and an infusion tube. The infusion apparatus is characterized in that the bottom of the infusion bottle is connected with the dripping bucket through the infusion tube, the inner side of the infusion tube is a cavity, the dripping bucket and the infusion tube are composites made from an outer layer of PVC and an inner layer of polyolefin thermoplastic elastomer, the bottom end is connected with an air exhaust filter through the infusion tube, the air exhaust filter comprises a shell and a spread sphere, air-permeable membrane is arranged on the inner side of an upper semi-circle between the shell and the inner part of the spread sphere, precision filtration membrane is arranged on the inner side of a lower semi-circle, air exhaust holes are arranged in the shell, and soda division plate is arranged at the connection place of the precision filtration membrane and the air-permeable membrane. The composite type safety infusion apparatus can be generally applied to infusion bottles and infusion bags, in the applicable process of the two, the application and the operation are simple, the service efficiency is improved for the patients, and the structure is simple, the application is easy, and the promotion and the application are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a composite safety infusion set. Background technique [0002] Disposable infusion set is a kind of medical device with large consumption and wide range of use. According to statistics, the annual consumption in the whole country reaches more than 5 billion. Therefore, the quality of the infusion set and the safety of use are directly related to the health of the patient. At present, domestic disposable infusion sets generally use PVC raw materials. Although this material has the advantages of excellent mechanical properties, low price, and simple production process, when transporting drugs such as paclitaxel, there is a solvent in the dispensing process that is easy to dissolve the PVC material. Additives such as plasticizers dissolve into the medicine, causing the medicine liquid to be turbid, which is likely to cause adverse reactions to patients. It can be seen th...
