Description

Soft cleaning brush for endoscope power tool

Technical Field

The invention relates to the field of cleaning of soft endoscopes, in particular to a cleaning brush for a soft endoscope power tool.

Background

With the continuous development of endoscopic technology, gastroscopy has become an essential means for diagnosing and treating digestive system diseases. The gastroscope is used as an instrument invading into the human body cavity, and the structure is complex, the material is special, the complete sterilization requirement is not easy to achieve, and the chance of iatrogenic infection is greatly increased once the defense barrier of the human body is damaged during operation. When the soft endoscope is disinfected or sterilized by using a chemical disinfectant, the sterilization and sterilization are carried out according to the use instructions, and chemical monitoring and biological monitoring are carried out. When disinfection or sterilization is performed by soaking in disinfectant, the cleaned and dried endoscopes should be placed in a disinfection tank and completely immersed in the disinfectant, and the disinfectant is filled in each channel by using an injector. The operation part of the non-full-immersion endoscope needs to be wiped by clean water and then wiped by 75% ethanol for disinfection.

Most of the existing soft endoscope cleaning brushes are single in structure, bristles are arranged at the head ends of the brushes, the bristles at the head ends are harder than the brush bodies, the flexibility is insufficient, in addition, the design of the existing cleaning brushes is afraid of too long design of the bristles at the front ends, because the resistance of the brushes in the reciprocating walking of the soft endoscope is too large, because the manual cleaning bodies are soft, the manual operation of the cleaning brushes is easy to block, the cleaning brushes cannot be pulled back and forth like a hard brush, the cleaning brushes can be pulled back and forth in a short time, and the cleaning brushes can be blocked more easily in the inserting process, so that a cleaner always cleans an inner cavity because the soft endoscope cleaning brushes are too long (the length is 2200mm), the general cleaner only pulls the cleaning brushes back and forth in the inner cavity, and the whole cleaning effect is greatly reduced. The cleaning personnel need to pull the cleaning brush many times quickly during cleaning, and the cleaning personnel is easy to fatigue during operation, so that the reciprocating times, frequency and compliance of the cleaning personnel in the active cleaning cavity are not high. The cleaning brush with the length of about two meters has short hair body parts, the hair body parts account for less than 1 percent of the total length, and are only distributed at one end or two ends of the cleaning brush, so the cleaning brush is inconvenient to use or the hair body is deformed, the abrasion in the cavity of an instrument can be caused, the effect is also reduced, and the endoscope cleaning and disinfecting quality is difficult to control.

The nano silver particles are antistatic, have lasting antibacterial performance and no drug resistance, and the addition of the nano silver particles has no influence on the color of the drawn bristles. The antibacterial performance of the nano silver can be reduced in the high-temperature melting and wire drawing process, but after the nano silver is placed for a period of time, the valence state of the nano silver is changed under the action of light and air, the nano silver is dissolved out from the surface of the bristle filament, and the antibacterial activity of the bristle filament is recovered. The sterilization mechanism of the silver ions is as follows: when the silver ions contact the cell membrane of the microorganism, the silver ions enter the cell due to the fact that the cell membrane is negatively charged and is coulometrically attracted with metal ions, and then interfere with the activity of enzyme protein or nucleoprotein, so that the effect of killing the microorganism is achieved. The antibacterial brush hair prepared by the invention has high oxidation activity of titanium dioxide, is harmless to human bodies, is a photocatalytic inorganic antibacterial agent, can kill bacteria in contact with the titanium dioxide in a short time after illumination, can generate oxidized OH free radicals for all organic matters, has wider antibacterial spectrum than that of metal ions, and has larger dispersion area, larger contact area with the bacteria and better antibacterial effect under the action of a carrier of silicon dioxide or zeolite.

The working principle is as follows: when the power tool cleaning brush is used, the round beads 4 at the head part of the brush enter the endoscope body from a water injection port or an air port of the soft endoscope, the brush can do high-frequency reciprocating motion in the soft endoscope, so that the inside of the endoscope is smooth and unobstructed, and the brush can be specially used for cleaning the brush of the power tool and can also be used for manual cleaning.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
