Catheter auxiliary guide optical fiber indicating rod

Abstract

The invention discloses a catheter auxiliary guide optical fiber indicating rod, which comprises an optical fiber indicating rod, a circular truncated cone elastic fixer, a bullet base, a double-sided convex lens and an indicating rod sleeve, the circular truncated cone elastic fixer is nested on the indicating rod, and various catheters with different diameters can be plugged and sleeved by pushing the fixer and are movably matched with the indicating rod, the bullet base can be tightly fixed to the rear end of the balance weight indicating rod to prevent rotation, the miniature double-sided convex lens can be screwed in to adjust the size of a focal length light spot and the thickness of light, laser is gathered and amplified to guarantee sufficient light source brightness, and a printed circuit board, a laser transmitter module and a 18650 lithium battery power supply are arranged in a corresponding indicating rod sleeve to form a path projection light source. By adopting an embedding bonding and thread mutual connection mode, the structure is compact, the light source brightness is high, the indicating performance is high, practicability, simplicity, convenience and rapidness are achieved, and the problems that in the prior art, the brightness is poor, positioning is difficult, and shaking and instability are caused during tube placement are effectively solved.

Description

Technical field: [0001] The invention relates to an airway management control tool-a catheter-assisted guiding optical fiber indicator rod. Background technique: [0002] In terms of clinical airway management, clinicians in the emergency department, intensive care unit, anesthesiology department and other clinicians can quickly open the airway and control breathing in emergency situations. Poor activity, neck muscle hypertrophy, and throat with sputum, blood stains, vomit, etc., the existing intubation tools have poor brightness, poor guidance and indication functions, shaking during positioning and tube placement, and need to raise the head and jaw. Dark field or turning off the indoor light source, etc., the operating conditions are complex and demanding. Invention content: [0003] The purpose of the present invention is to provide a catheter-assisted guidance optical fiber indicator rod based on breaking through the above scene conditions. The shape and structure con...
