Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a device for epidural analgesia puncture combined with body positioning and fixation. Background Technology

[0002] During epidural analgesia puncture, pregnant women need to maintain a forward flexed and curled position for a long time, i.e., "arched like a shrimp," to fully expose the intervertebral space for easy puncture; current clinical practice mainly relies on human support and suggested tools.

[0003] However, when medical staff manually stabilize the pregnant woman's shoulders and feet, there are problems such as high physical exertion, poor stability, and easy displacement of the body due to the pregnant woman's fatigue. If ordinary fixation straps or soft pads are used for assistance, it is impossible to accurately adjust the height and angle of the support point, and there is a lack of anti-slip design, so the pregnant woman's body is prone to slipping when she exerts force due to pain.

[0004] The aforementioned problems may prolong puncture time, increase operational risks, and even lead to puncture failure; therefore, there is an urgent need for a dedicated body positioning fixation device that can be quickly installed, is multi-dimensionally adjustable, and conforms to ergonomics.
