Description

Lumen analog test strip capable of monitoring penetration capacity of sterilizer Technical Field The utility model belongs to the technical field of medical supplies, and particularly relates to a lumen simulation test strip capable of monitoring the penetrating capacity of a sterilizer. Background Sterilizer-a sterilizer is a device that is specially designed to thoroughly kill or remove all microorganisms, including bacteria, viruses, fungi, spores thereof, etc., to ensure that the articles or environment are sterile. Its core function is to destroy the living structure or metabolic capability of the microorganism by physical or chemical means, thereby eliminating its activity. Sterilization is a critical step in the medical, pharmaceutical and food processing industries to ensure product safety and prevent microbial contamination. The sterilizer is used as a core device for achieving the aim, and the performance of the sterilizer directly influences the sterilization effect. The penetration capacity of a sterilizer refers to the ability of a sterilization factor (e.g., high temperature steam, ethylene oxide, hydrogen peroxide, etc.) to penetrate and effectively kill microorganisms. This capability is particularly important to ensure sterilization of the interior of complex instruments, such as luminal-like instruments. In the medical industry, the use rate of lumen-type instruments (such as endoscopes, catheters and the like) is increasing year by year, and due to the complex internal structure, the attention of people to the sterilization effect is also increasing. At present, the lengths of the lumen instruments on the market are different, and the sterilization effect for monitoring the lumen instruments is usually carried out through a lumen simulator, for example, a simulation sheet is placed at the tail end of a lumen simulator with the length of 1m, and the sterilization effect of the simulation sheet is observed. Disclosure of utility model The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing a lumen analog test strip capable of quantifying the penetration capacity of a sterilization factor. The technical scheme includes that the lumen simulating test strip capable of monitoring the penetrating capacity of the sterilizer comprises a carrier layer, an indicating ink layer and a film layer, wherein the indicating ink layer is arranged between the carrier layer and the film layer, openings are formed in two ends of the carrier layer and the film layer in the length direction, and a graduated scale is arranged on the carrier layer. The carrier layer is flexible material, can monitor the length setting arbitrary length of lumen class apparatus as required to can coil with lumen class apparatus and place in the sterilizer, simulation effect is good. Preferably, the width of the indicating ink layer is smaller than the width of the carrier layer and the length is the same as the length of the carrier layer. Preferably, the length of the carrier layer is 1 to 5m. Preferably, the dividing ruler is provided with two dividing rules, the dividing rules are arranged on the upper side and the lower side of the carrier layer, and the indication ink layer is arranged between the two dividing rules. Preferably, the carrier layer is the same size as the film layer. Preferably, the film layer is made of PE or PVC or PET. Preferably, the material of the carrier layer is PET.
