AI Technical Summary

Technical Problem

Existing arm fixation devices, when used on patients whose puncture point is not in the elbow area, cause arm muscle fatigue due to prolonged immobilization, affecting their quality of life and preventing them from moving their elbow joint within a certain range of angles.

Method used

An arm fixation device was designed, including a first support plate and a second support plate. The angle is adjusted by rotating the sleeve and the rotating column, and the range of motion of the elbow joint is fixed or adjusted by a locking mechanism to meet the needs of patients whose puncture points are in the elbow area and those whose puncture points are not in the elbow area.

Benefits of technology

This method achieves complete fixation of the puncture point in the elbow area for patients, and allows the elbow joint of patients whose puncture point is not in the elbow area to move within a certain range of angles, reducing arm fatigue and improving the dialysis experience and quality of life.

Abstract

The utility model discloses an arm fixing device, particularly relates to the technical field of medical instruments, and is used for solving the technical problem that the existing arm fixing device cannot enable an elbow joint to rotate within a certain range. The device comprises a first fixing band and a second fixing band, a first supporting plate is arranged on the first fixing band, a second supporting plate is arranged on the second fixing band, a sleeve is arranged at one end of the first supporting plate, a rotating column rotationally arranged in the sleeve in a sleeved mode is arranged at one end of the second supporting plate, and a fan-shaped opening is formed in one end of the sleeve. A first limiting rod and a second limiting rod are axially and rotationally connected to one end of the sleeve in sequence in an overlapped manner; a limiting block is arranged on one side of the rotating column and arranged between the first limiting rod and the second limiting rod, and a locking assembly is arranged between the first limiting rod and the sleeve and between the second limiting rod and the sleeve. According to the device, the rotation range of the angle between the first supporting plate and the second supporting plate is adjusted through the adjusting mechanism, so that the elbow joint of a patient rotates within a certain angle range.
