Novel infusion apparatus

Abstract

The invention discloses a novel infusion apparatus which comprises a pressurizing mechanism used for maintaining infusion pressure to be stable, a liquid mixing mechanism used for adding antibiotics medicine and a cut-off connector used for changing the flow direction of liquid medicine, and the liquid mixing mechanism comprises a liquid mixing pipe and ejector pins symmetrically distributed at the end of the liquid mixing pipe. The liquid mixing pipe is communicated with the ejector pin through a hose, a floating ball used for automatically intercepting and blocking flow is arranged in the liquid mixing pipe, and a vent hole and a first heparin cap are arranged on the left side and the right side of the upper end of the liquid mixing pipe respectively. According to the novel infusion apparatus, through the arrangement of the pressurizing mechanism, the liquid mixing mechanism, the cut-off connector, the lower Y-shaped connector and the second heparin cap, the infusion speed can be kept stable, the problem that an existing infusion apparatus cannot achieve one-time intravenous injection of large-dose liquid medicine is solved, and through the arrangement of the cut-off connector, the infusion speed can be increased greatly. The flow direction of the liquid medicine can be automatically switched, meanwhile, the liquid mixing pipe is convenient to mount and dismount, and use in practical operation is facilitated.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a novel infusion set. Background technique [0002] A traditional disposable infusion set consists of a trocar, an infusion hose, a vent tube, a Murphy dropper, a governor, a filter element, and a needle. This disposable infusion set has been widely used in clinical practice. However, there are the following problems: the traditional infusion set mostly adopts the hanging method for infusion, the liquid medicine bag needs to be hung on a bracket of a certain height, and the patient needs to lie down to achieve the best infusion effect. When starting, there will be a problem that the infusion pressure is not enough to cause the blood to return. Some infusion sets have the function of pressurizing, but the pressure exerted by them is mostly unadjustable. As the solution in the liquid bag gradually decreases, the speed of the infusion The infusion rate is also reduced, resulting in...

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the present invention is to provide a new type of infusion set, which can keep the infusion speed stable through the provided pressurizing mechanism, liquid mixing mechanism, shut-off joint, lower Y-shaped joint and second heparin cap, which solves the problem of existing infusion problems. The device can not realize the problem of one-time intravenous injection of large doses of liquid medicine. Through the cut-off joint, it can not only realize the automatic switching of the flow direction of the liquid medicine, but also facilitate the installation and disassembly of the mixing tube, which is convenient for practical use. Effectively solve the problems in the background technology
