Background
Intravenous injection therapy is to drip medicine into blood vessels of human body through an infusion apparatus in an intravenous infusion mode, and is one of the most widely used clinical treatment modes at present. However, in the using process, the infusion apparatus is easy to fall off due to being pulled by external force, and the infusion apparatus is polluted, and if the patient is self-treated or not treated in time, the injection infection of the patient is easily caused.
The infusion apparatus is easy to be dropped by the patient for a long time, but the problem cannot be solved at the time of product updating, and the reasons are as follows: firstly, the infusion apparatus is the most basic medical apparatus for treatment, the use amount is very large, and the characteristics of simple structure, convenient use, easy mass production and relatively low price are required to be clinically and widely applied. Secondly, to increase the anti-drop function, parts must be added in design; however, the characteristics of simple structure, convenient use, easy mass production and relatively low price are broken, so that the popularization is hindered. If there is octopus formula transfusion system now, utilize eight claw fixer to prevent that the transfusion system from droing, eight claw fixer include disc, sleeve pipe and stationary dog, and the centre bore has been seted up to disc and sheathed tube center department, and eight mounting grooves have evenly been seted up to the up end of disc, and the inside of mounting groove is rotated through the pivot and is connected in the middle part of stationary dog, and the bottom of stationary dog is rotated through the pivot and is connected in the recess that the branch top was seted up. The existing structural design easily breaks through the basic characteristics of the infusion apparatus in clinical application, and the infusion apparatus is easy to drop due to the fact that the infusion apparatus is not firmly held in the process of changing the infusion liquid medicine, so that the practicability is low.
Therefore, there is a need for a design that can increase the anti-drop function, and at the same time, maintain the features of simple structure, convenient use, easy mass production, and relatively low price, and has a wide adaptability, and can be applied to infusion bags or infusion bottles of different specifications, and many application scenarios.
