Electric intraosseous infusion system

Abstract

The invention provides an electric endosseous infusion system. The electric endosseous infusion system comprises an infusion needle component and a puncturing control component, wherein the infusion needle component comprises an infusion needle assembly, a puncturing needle assembly and a shell assembly; the puncturing control component is in the shape of a gun, and comprises two parts namely an emitting bin and a power bin; the emitting bin comprises an automatic needle pushing assembly, a magazine type needle storing box, a shell ejection assembly arranged at the front end of the magazine type needle storing box and a shell ejection window formed in the upper part of the shell ejection assembly; the power bin comprises a needle pushing bin and a power source bin; a power assembly, a transmission assembly of which one end is connected with the power assembly and the other end cooperates with a sleeve, a depth limiting blocking piece mounted on the transmission assembly, a sliding cover plate of which one end is fixedly connected with the depth limiting blocking piece and the other end can cover the shell ejection window under the pushing of the depth limiting blocking piece, an adjustable depth limiting indicating assembly and a depth limiting blocking piece limiting mechanism are arranged in the needle pushing bin; and a power source is arranged in the power source bin, and acontact button is arranged on the outer wall of the power source bin.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an electric intraosseous transfusion system for quickly establishing a fluid resuscitation channel during emergency rescue. Background technique [0002] It is very important to quickly establish the infusion channel in the rescue to ensure the infusion and drug administration. Bone marrow infusion technology is currently the only non-venous infusion method. Compared with traditional intravenous infusion technology, it has the advantages of convenience, speed, safety, high success rate, and the operator does not need long-term professional training. This technology expands the effective needle application area from a few millimeters of the vein to 4-5 cm in the flat area of ​​the bone. It is easier to locate patients with collapsed veins and has a higher success rate of needle application. It can be quickly implemented even at the rescue site and during transp...

Problems solved by technology

The manual FAST1 system and the ejection BIG system rely on mechanical force and spring mechanical force to perform puncture, which have high technical requirements for the operator, long operation time, and are likely to cause fractures at the puncture site, severe pain, and breakage of the infusion needle. At the same time, due to uneven strength or operator error, the infusion needle is not fixed firmly, which may cause the infusion needle to fall off and leak, which will lead to serious complications such as osteofascial compartment syndrome.

[0004] The electric EZ-IO system uses electricity to rotate the infusion needle into the bone marrow, avoiding the defects of the previous two intraosseous infusion systems, but this system needs to manually install the infusion needle on the drill bit and remove the infusion needle protective cover The puncture can only be performed after it is inserted, so the requirements for disinfection operations are high, and the system needs to prepare puncture needles of different lengths according to different puncture sites, which is not easy to carry out
