AI Technical Summary

Technical Problem

The C-shaped snaps of the extension tube and the cannula of the existing ventilator lack radial clamping function, is poor in practicality, cannot adapt to pipe ports of different diameters, and the elasticity of the connection depends entirely on friction, which leads to easy loosening when the patient's body is active, increasing the working strength of nurse care and may lead to medical accidents.

Method used

A radial clamping mechanism is designed, including a C-ring and a centering clamping block. The relative movement of the centering clamping block is realized through the clamping drive mechanism. The transmission assembly and the linkage assembly are used to drive the four centering clamping blocks to move simultaneously, and adapt to the extension tubes of different pipe diameters to fix them with the cannula. At the same time, a tensile connection assembly is used to make the opening ring have tensile force, which enhances the connection between the extension tube and the cannula.

Benefits of technology

The extended tubes with different diameters are stable and fixed, with high adaptability and strong firmness, which solves the problem that C-shaped snaps cannot be adjusted only through friction connection, improves the safety of patients and reduces the incidence of medical accidents.

Abstract

The utility model relates to the technical field of anti-falling buckles, in particular to a radial clamping mechanism and an anti-falling buckle of a breathing machine, which comprises a clamping ring part, a clamping part, a clamping part and a clamping part, the clamping ring part comprises a C-shaped ring and centering clamping blocks symmetrically arranged on the inner side of the C-shaped ring, and a clamping driving mechanism used for driving the centering clamping blocks to move relatively is arranged in the C-shaped ring; the clamping driving mechanism comprises two linkage assemblies symmetrically arranged in the C-shaped ring, and the two linkage assemblies are driven through a transmission assembly. The four centering clamping blocks can be driven to synchronously and relatively move by matching the transmission component with the linkage component, so that extension tubes with different tube diameters can be fixed with the intubation tube, the adaptability is higher, and the firmness is higher; the extension tube and the cannula can be connected more firmly by stretching the connecting assembly, the defect that an existing C-shaped buckle cannot be adjusted and is connected only through friction is overcome, the use safety of a patient is improved, and the occurrence rate of medical accidents is reduced.
