Description

Technical Field

[0001] This utility model relates to the technical field of medical surface sampling and framing devices, specifically a standardized framing device for medical surface sampling based on laser projection. Background Technology

[0002] In hospital infection control monitoring, surface microbial sampling is a core step in assessing environmental cleanliness and disinfection effectiveness (according to the "Hospital Disinfection and Hygiene Standards" GB15982-2012). Current routine clinical procedures are as follows: Reliance on paper templates: Using rigid plastic / paper sampling frames of fixed sizes (such as 5cm×5cm, 10cm×10cm, etc.) requires pre-cutting or carrying multiple sizes of templates, but there are problems such as easy loss, inconvenience in carrying, and easy contamination after repeated use. Hand-drawn borders: In some scenarios, medical staff use markers to draw lines on the table by hand as sampling frames, but the lines are uneven in thickness and the corners are not perpendicular, resulting in a large deviation between the actual sampling area and the standard requirements (the error can reach ±10%-15%), affecting the accuracy of the test results; Temporary measurement and marking: This involves measuring and marking lines on-site with a ruler, which is cumbersome (requiring multiple calibrations), time-consuming (each framing session takes about 2-3 minutes), and dependent on the operator's experience. It also has a low degree of standardization. Clinically, there is an urgent need for a sampling framing tool that does not require contact with the object surface, can project quickly, has adjustable size, and has a high degree of standardization, in order to solve the problems of contamination risk, cumbersome operation, and insufficient accuracy of existing methods. To this end, we propose a standardized framing device for medical object sampling based on laser projection. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a standardized framing device for medical surface sampling based on laser projection, thereby resolving the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a standardized framing device for medical surface sampling based on laser projection, comprising a projection component, a fixing component, and an adjustment component. The projection component includes a housing, and an adjustment screw is rotatably connected to the outer wall of the housing. A cross-shaped outer shell is provided at one end of the housing near the adjustment screw. The fixing assembly includes a sleeve fixedly assembled to the outer wall of the housing.
