Description

Gastrointestinal endoscope suction duct brush guide

Technical field

The invention belongs to the technical field of medical devices, and particularly relates to a brush guide for the suction duct of a digestive endoscope.

Background technique

Digestive endoscopy is of great significance in the diagnosis and treatment of digestive tract diseases. With the continuous development of new technologies, digestive endoscopy is not only used for the diagnosis of digestive system diseases, but also for the treatment of some digestive tract diseases, and even some Diseases in the traditional surgical field can also be treated endoscopically, replacing surgical treatments. As the number of diagnosis and treatment cases increases, the risk of transmission of pathogenic microorganisms caused by endoscopy also increases.

The digestive endoscope is a reusable diagnostic and treatment instrument with a delicate structure, complex lumen, and special materials. It is not easy to clean and is not suitable for high-temperature and high-pressure disinfection. Most use chemical disinfectants for soaking or sterilization. Standardized cleaning and disinfection is the key to preventing and controlling infections related to digestive endoscopes, and is an issue that endoscopists must attach great importance to. Each patient undergoing endoscopy should be considered a potential source of infection. Standard endoscope cleaning and disinfection can avoid cross-infection, and the time and cost are relatively low. Therefore, all used endoscopes and accessories should be decontaminated in accordance with scientific standards for endoscope cleaning and disinfection. Microorganisms embedded in organic matter, such as blood, mucous membranes, and secretions prevent the penetration of antiseptics and may cause disinfection failure. Strict mechanical cleaning to remove the outside of the insertion tube and all accessible luminal materials is necessary before disinfection and sterilization.

The "2014 Chinese Expert Consensus on Cleaning and Disinfection of Digestive Endoscopes" points out that thorough manual cleaning is a prerequisite for manual disinfection and automatic machine disinfection and cannot be omitted. Use a special cleaning brush to scrub all endoscope ducts and accessory ducts. The brush must scrub the ducts several times until clean. The brush must be cleaned each time it passes through the duct. The "Technical Specifications for Cleaning and Disinfection of Flexible Endoscopes (WS507-2016)" points out in the cleaning process: When scrubbing all pipes of a flexible endoscope, the brush heads should be seen at both ends, and the dirt on the brush heads should be washed away, and brushing should be repeated until There are no visible contaminants.

However, the existing digestive endoscope cleaning process has the following shortcomings:

The suction tube of the digestive endoscope is divided into two parts at the entrance below the suction button of the operating part. The insertion part suction tube and the light guide joint side suction tube have a certain angle (about 45°). The light guide joint side suction tube is parallel to the entrance. Continuation, and the insertion part suction pipe has a certain angle with the entrance. When using a cleaning brush to clean the suction pipe on the side of the light guide connector, you can enter directly, but when cleaning the suction pipe at the insertion part, you need to find an angle to enter. Based on experience, cleaning personnel often put their fingers above the side edge of the entrance to guide the brush to enter. There are many Disadvantages: 1. Due to the heavy workload in the endoscopy room and the limited number of digestive endoscopes, strict quality requirements for cleaning and disinfection, the process is time-consuming and requires rapid manual cleaning of the internal pipelines in a short period of time. The above operation process is difficult to grasp in the process of finding the angle. , due to angle requirements, the position of the finger pads will vary from person to person, and is more susceptible to interference from human factors, such as: extended working hours, energy consumption, causing muscle strain that cannot guarantee accurate operation techniques; or skin abrasion increases the risk of infection, etc.; 2 . During the process of exploring the angle and entering the brush, it will cause repeated wear and tear on the entrance. After wear and tear, the repair cost is extremely high, resulting in waste of resources and increased costs; 3. During the process of exploring the angle, it will also cause the front end of the cleaning brush to be distorted. Deformation and wear affect the quality and efficiency of cleaning work, and frequent replacement increases the cost of consumables.

To sum up, the shortcomings of the traditional digestive endoscope cleaning process are as follows:

1. The operation process is cumbersome and error-prone, affecting work efficiency.

2. It causes repeated wear and tear on the entrance. After wear and tear, the repair cost is extremely high and medical costs are increased; the front end of the cleaning brush is distorted, deformed, and worn.

3. It is time-consuming and labor-intensive, and there is a risk of infection when the staff has wounds on their fingers.
