Aseptic cotton bud used for medical apparatus and instruments

Abstract

The invention relates to an aseptic cotton bud used for medical apparatus and instruments. The aseptic cotton bud is composed of a cotton bud rod, a hand-held handle and a bud head, wherein the head end of the cotton bud rod is pinpoint-shaped, the tail end of the cotton bud rod is connected with the hand-held handle, the length of the cotton bud rod is 5-6 cm, the diameter of the cotton bud rod is 1mm, the length of the head end of the cotton bud rod is 0.5-0.6 mm, the included angle alpha between the inclined surface of the head end of the cotton bud rod and the axis of the cotton bud rod is 30-45 degrees, the diameter of the hand-held handle is greater than that of the cotton bud rod, and the bud head tightly wraps the periphery of the head end of the cotton bud rod. The head end of the aseptic cotton bud is sharp, thus being capable of easily penetrating the structure such as a groove for cleaning dirt and cleaning the blood scab on a threaded hole, the shortened cotton bud rod enables the aseptic cotton bud to have the small possibility of breaking off, the thickened hand-held handle is convenient to hold, and the medical apparatus and instruments, such as the intravenous catheter, needing long-time indwelling can be completely cleaned and disinfected easily, the residue of dust, dirt and bloodstain is avoided, and the occurrence of adverse events such as catheter infection is reduced.

Problems solved by technology

This kind of cotton swab has the same size, beautiful appearance, easy to use, and is very popular. However, the existing medical cotton swabs are all of the same specification, especially the head of the cotton swab is: length*width 2cm*0.5cm, and some existing medical devices have long-term retention Features, such as: the semi-permanent catheter placed in the deep vein of maintenance hemodialysis patients needs to be strictly disinfected regularly. In addition to the threaded part of the catheter nozzle, the disinfection of the groove part of the catheter closing clamp is a difficult point in clinical work. Large, unable to go deep into the groove and completely remove the blood scab at the threaded mouth, resulting in dust, dirt, and blood stains on the nozzle 2, leading to adverse events of catheter infection
