Hose connection machine and hose connection method

Abstract

The invention provides a combined heating-temperature-adjustable hose connection machine, wherein at least two hoses (7) are fixed by a fixture 1 (3) and a fixture 2 (4) fix and are substantially parallel to each other, a combination sheet (30) is maintained in a heating structure (40), the heating structure (40) can heat the combination sheet (30) to a preset temperature, and the preset temperature can be adjusted according to actual conditions, such that the use of the hose connection machine is not limited by the ambient temperature and the material of the hose so as to conveniently use.

Description

technical field [0001] The invention relates to a splicing machine which combines after heating and cutting the hoses, in particular to a splicing machine whose heating temperature can be adjusted. Background technique [0002] When combining blood collection bags and blood component bags, or for component separation, component mixing, sampling and other operations in biopharmaceuticals, tubes must be combined aseptically. The traditional acupuncture method has many defects. The current alternative The method is to use a pipe connecting machine for heating and welding. The specific method is to use a fuse device heated to a fixed temperature to fuse the hoses to be joined together, which better solves the problem of aseptic joining of the pipes; however, the above-mentioned pipe joining The equipment has the following disadvantages: the heating temperature is generally a fixed value, such as 260°C, so this type of equipment has strict requirements on the ambient temperature ...

[0002] When combining blood collection bags and blood component bags, or for component separation, component mixing, sampling and other operations in biopharmaceuticals, tubes must be combined aseptically. The traditional acupuncture method has many defects. The current alternative The method is to use a pipe connecting machine for heating and welding. The specific method is to use a fuse device heated to a fixed temperature to fuse the hoses to be joined together, which better solves the problem of aseptic joining of the pipes; however, the above-mentioned pipe joining The equipment has the following disadvantages: the heating temperature is generally a fixed value, such as 260°C, so this type of equipment has strict requirements on the ambient temperature used (generally higher than 20°C), which limits its working environment and occasions; At the same time, because the pipelines of biopharmaceuticals and blood collection bags have various specifications and materials, different specifications and materials have large differences in the temperature requirements for bonding after fusing, so that the equipment required for combining different hoses is not the same. causing a lot of inconvenience
