Description

Technical Field

[0001] This invention belongs to the field of endoscopic laboratory instrument technology, specifically relating to a liftable and movable flexible endoscope microbial culture and detection rack. Background Technology

[0002] Endoscopy is widely used in clinical diagnosis and treatment, playing a crucial role, particularly in the diagnosis and treatment of diseases of the digestive, respiratory, and urinary systems. As an invasive instrument, endoscopes are prone to infection; therefore, strict infection control is essential. Inadequate infection control can lead to worsening of the patient's condition, prolonged hospitalization, and even death. If endoscopes and accessories are not thoroughly cleaned and disinfected, bacteria, viruses, and other microorganisms released from the patient's respiratory and digestive tracts can be transmitted to other parts of the body or the patient during subsequent endoscopic procedures.

[0003] Endoscopic infection control culture sampling mainly targets the inner lumen surface of the endoscope, using the rinsing method for microbial monitoring to assess the disinfection effect.

[0004] The current standard sampling procedure is as follows: 1. Draw 50ml of eluent containing the appropriate neutralizing agent using a sterile syringe; 2. Inject into the biopsy port of the endoscope to be examined, and collect from the biopsy port using a sterile container; the specific operating steps are as follows: Procedure for collecting endoscopic culture medium: 1) Item preparation: Eluent / bottle containing 50ml of the corresponding neutralizing agent, sterile syringes (20 / 50ml), 50ml sterile empty bottle, marker pen, sampling plan, hand sanitizer, sterile test tube containing 10ml of neutralizing solution, alcohol lamp, lighter, sterile scissors, sterile cotton swabs.

[0005] (2) Sampling personnel preparation: Wear masks, hats, and clean work clothes, maintain hand hygiene, and wear sterile gloves and disposable surgical gowns when necessary.

[0006] (3) Sampling objects: According to the technical specifications for cleaning and disinfection of flexible endoscopes (WS 507-2016), the sampling objects are the disinfected endoscopes in the endoscopy room, the disinfectant or sterilizing agent in use, hand hygiene, and environmental surfaces.

[0007] (4) Sampling frequency: Routine monitoring is conducted once a quarter. Monitoring should be conducted promptly in the event of a hospital infection outbreak or after the installation or repair of a new endoscope cleaning and disinfection machine.

[0008] (5) Sampling method: a. Disinfected endoscopes: A rotating sampling method is adopted, with 25% of the endoscopes sampled each time. If there are 5 or fewer endoscopes, all of them should be monitored each time. If there are more than 5 endoscopes, at least 5 endoscopes should be monitored each time (for example, if a hospital has a total of 40 disinfected endoscopes, 10 endoscopes should be sampled each quarter to ensure that all 40 endoscopes are monitored throughout the year). Sampling time: Sampling is performed after the endoscope is disinfected and sterilized, but before use.

[0009] Sampling method: Use a sterile syringe to draw 50 ml of eluent containing the corresponding neutralizing solution, inject it into the biopsy port to flush the endoscope tubing, and use the sampling bottle on the stage to collect the full amount of sampled fluid at the tip of the endoscope and send it for testing in time.

[0010] Criteria for judging the effectiveness of endoscope disinfection: The total number of bacteria in the disinfected endoscope is ≤20 CFU / piece, and no pathogenic bacteria are detected.

[0011] Currently, culture requires two people to operate: one person holds the endoscope and injects the culture medium, while the other person holds the other end of the endoscope outlet with one hand and the culture bottle with the other, which consumes manpower and increases the chance of contamination. Summary of the Invention

[0012] The purpose of this invention is to disclose a liftable and movable collection rack for microbial culture and detection of flexible endoscopes.

[0013] The objective of this invention is achieved through the following technical solution: A liftable and movable collection rack for microbial culture testing of flexible endoscopes, wherein: the rack includes a fixing tube (6) set on a base; a platform (4) is provided at the lower part of the fixing tube (6). The testing frame also includes a sliding tube (5), a lifting wire tube (1), a lifting control panel (7), a drive motor (8), and an endoscope main unit light guide connector placement box (3); wherein the sliding tube (5) is sleeved on the outside of the fixed tube (6); the lifting wire tube (1) is L-shaped, the free end of the horizontal tube of the lifting wire tube is fixed on the fixed tube (6), the vertical tube is parallel to the sliding tube and the top is open; one end of the drive motor (8) is fixedly connected to the sliding tube (5), and the other end can be raised and lowered along the lifting wire tube (1); the lifting control panel (7) and the drive motor (8) are connected by circuit, and the lifting motor (8) is controlled to rise and fall on the lifting wire tube (1) according to the button instructions of the lifting control panel (7); the endoscope main unit light guide connector placement box (3) is provided on the sliding tube (5); the top of the sliding tube is provided with a curved hand-shaped placer (2) for placing the endoscope operating part.

[0014] The above technical solution describes a liftable and movable collection flexible endoscope microbial culture detection rack, wherein: the drive motor (8) has a built-in worm gear device to convert the horizontal rotation of the motor into vertical rotation; an internal thread for transmission is machined at the center of the worm gear, and the internal thread cooperates with the lifting wire tube (1) to jointly control the lifting of the sliding tube (5) and thus control the position of the bent hand-shaped placer (2); The above technical solution describes a liftable and movable collection rack for microbial culture and detection of flexible endoscopes, wherein the stage (4) is a disc-shaped structure, which is fixed to the fixing tube (6) by welding or screws. In this technical solution, the disc-shaped structure is only a preferred option for the stage, and the staff can replace the stage (4) with a square, rhomboid or other shaped structure according to actual needs.

[0015] The above technical solution describes a liftable and movable flexible endoscope microbial culture and detection rack, wherein: the endoscope host light guide connector placement box (3) has a cup-shaped structure and an opening on its side that allows the endoscope connection part to pass through.

[0016] The above-described lifting and movable flexible endoscope microbial culture and detection rack includes: two loops, one above the other, on the rear panel of the lifting control panel (7), which are connected to a sliding tube. The control panel can be adjusted to different angles and heights by adjusting the fixing bolts behind each loop, depending on the operator's angle. Adjusting the angle and height of the control panel makes it easier for the operator to perform their work.

[0017] The above-described lifting and movable collection frame for microbial culture and detection of flexible endoscopes includes a base with four casters at its bottom.

[0018] The present invention has the following beneficial effects: 1. Using the detection frame of the present invention, no two operators are required when collecting samples. One person can collect the endoscopic culture medium. The collector can adjust the relative position between the sliding tube and the fixed tube by using the buttons on the lifting control panel, thereby adjusting the distance between the endoscope operating part and the stage, so that the culture medium flowing out of the endoscope insertion part can flow into the culture dish on the stage.

[0019] 2. With the use of the testing rack of this invention, the possibility of human contamination in the laboratory is reduced as the number of operators decreases, thus better ensuring the cleanliness of experimental materials and the accuracy of experimental results; at the same time, it also reduces the chance of contamination by bacteria and viruses outside the laboratory.

[0020] 3. The testing frame of this invention does not require two people to work together, and single-person operation also reduces the chance of operational errors.

[0021] 4. The testing frame of this invention can be operated by a single person, reducing the consumption of equipment worn by laboratory personnel; it is even more worthy of promotion and application in major public health events. Attached Figure Description
