Disposable extension tube

Abstract

The invention relates to a disposable extension tube comprising a tube body, and a medicinal liquid filter and a stop clamp arranged on the tube body. The medicinal liquid filter comprises an upper cover and a lower cover matched with each other, as well as a filter membrane assembled between the upper cover and the lower cover. A connector communicating with the filter membrane is arranged on theupper cover, and a needle tube communicating with the filter membrane is arranged on the lower cover. The connection of the upper cover and the needle tube by an adhesive is avoided, and the toxic pollution is reduced; moreover, the process flow of the connection of the upper cover and the needle tube by the adhesive is reduced, and thus the work efficiency is greatly improved; in addition, the scrapping of the whole extension tube caused by forgetting of assembly of a stop clamp or the damage of a stop clamp in the assembly process is prevented; the labor intensity is reduced, the work efficiency is improved, resources are saved and the scrapping of the extension tube due to the problems of the stop clamp is prevented.

Description

Technical field: [0001] The invention relates to a disposable extension tube. Background technique: [0002] Since the extension tube can be connected with electronic syringe pumps, electronic infusion pumps and other products, it can be extended during clinical infusion, so the extension tube has been widely used in intravenous injection. However, during the infusion process, insoluble particles and other foreign matter in the drug will also enter the body along with the liquid; these foreign matter such as insoluble particles entering the body with the liquid can induce cardiovascular and cerebrovascular system embolism and pulmonary embolism and other diseases. Because foreign matter such as insoluble particles is a potential danger to patients receiving infusion therapy. At present, adding a liquid medicine filter to the disposable extension tube is an effective way to prevent foreign matter such as insoluble particles from entering the human body; while the traditional...

Problems solved by technology

At present, adding a liquid medicine filter to the disposable extension tube is an effective way to prevent foreign matter such as insoluble particles from entering the human body; while the traditional liquid medicine filter requires the needle tube and the upper cover and the lower cover and the needle tube to be bonded together. Adhesive glue needs to be used multiple times; and the use of adhesive glue at the position in contact with the liquid medicine will cause greater harm to the human body due to the certain toxicity of the adhesive glue; in addition, the entire bonding process is complicated and the production efficiency is low

Furthermore, during the infusion process of the extension tube, it is necessary to use the stop clamp to open and close the extension tube. However, the existing stop clip needs to be inserted into the extension tube in advance during use; and in actual operation, Because it is assembled manually, it is often forgotten to assemble the stop clip, and the entire extension tube will be scrapped if the stop clip is not installed; in addition, if the stop clip is damaged during the assembly process, it cannot be disassembled and replaced, and it will still be damaged. The entire extension tube is scrapped; it not only increases labor intensity, reduces work efficiency, but also seriously wastes resources
