An automatic puncture device for trauma first aid diversion

Abstract

The invention discloses an automatic puncture device for trauma first aid drainage, which aims to realize automatic puncture drainage, has low environmental requirements for implementation, is easy to operate, and improves the timeliness of first aid. It includes an ejection mechanism, a flow guide tube and a puncture needle. The ejection tube, the ejection fixer and the ejector, the ejection tube and the ejection fixer are detachably connected coaxially and fixedly in turn, the end of the ejection tube away from the ejection fixer has an opening communicating with the cavity, the ejector and the puncture needle are coaxially embedded Sleeve connection, the guide tube is coaxially nested in the puncture needle, the guide tube and the puncture needle are arranged close to the opening, and the puncture needle can be separated from the ejector and the guide tube; the ejection mechanism also includes a trigger button and a buckle, the trigger button The activity is set on the ejection holder, the first spring is connected between the trigger button and the ejector, and the buckle is arranged on the side wall of the ejection holder. Press the trigger button, and the ejector can drive the puncture needle and the guide tube to eject.

Description

technical field [0001] The invention belongs to the field of medical security, and in particular relates to an automatic puncture device for trauma first aid diversion. Background technique [0002] Acute urinary retention is the most common emergency in urology in peacetime and wartime. In the battlefield environment, traumatic brain trauma coma, fracture complicated with spinal cord injury and perineal injury can all induce acute urinary retention. According to statistics, during the Vietnam War, the incidence rate of craniocerebral trauma was 7%-13%. With the increase in the use of high-tech weapons and changes in combat methods, this indicator rose to 21%-28% in the Afghanistan War and the Iraq War. In addition to craniocerebral trauma, the incidence of other blast-related injuries also increased from 56% in 2003-2004 to 76% in 2006, among which the incidence of spinal fractures was 5.4%-11.0%, and about 18% were associated with spinal cord injuries. The incidence of p...

Problems solved by technology

However, there is still a blank in the field of research and development of first-line emergency catheterization equipment, and related equipment has not been reported abroad.

Commonly used methods of urinary catheterization in clinical practice, such as urinary catheterization and suprapubic cystostomy, have many limitations such as catheterization contraindications for urethral injury, complicated bladder fistula operation, and high risk of urinary tract infection in the first aid of war trauma

Other treatment methods, such as percutaneous ureterostomy, percutaneous nephrostomy, urethral reunion, indwelling catheterization under direct vision of ureteroscope, etc., can only be used clinically in the hospital and extended to second-line field rescue at most
