1. Material and Craftsmanship
- Core material : Most likely made of medical-grade stainless steel (such as 304 or 316L), it exhibits excellent biocompatibility, resistance to acid and alkali corrosion, and high mechanical strength, meeting the safety standards for medical device materials and being compatible with disinfection and sterilization processes.
- Processing technology : Machined using high-precision CNC turning, milling, tapping, and other processes, the dimensional tolerances of threads, internal bores, and external diameters can be controlled to the micrometer level. The surfaces undergo polishing and passivation, eliminating burrs and sharp edges, thereby reducing the risk of bacterial residue while ensuring tight sealing and smooth assembly.
2. Analysis of Part Structure and Function
Location Part Appearance Features Typical Applications and Functional Inference Top left Step shaft component with annular heat dissipation and locating grooves, featuring a small hole at the top. Signal and fluid‑transfer connectors commonly used in medical sensors; stepped grooves can aid heat dissipation or serve as a keying feature for secure alignment, while small holes function as media or signal channels. Left center Step-shaped part with a flange, the flange features two locating holes. The flanged mounting connector for medical devices achieves sealed fixation between units via bolt holes, while the stepped structure serves to position and install the sealing element. Middle and upper A nut-shaped part with a hexagonal outer profile and external threads, featuring an internal threaded hole at the top. Designed for sealed connections in pipelines or equipment, its hexagonal structure facilitates wrench tightening, while the internal and external threads enable bidirectional assembly, accommodating medical tubing of various specifications. Middle and lower A capped component with a hexagonal outer profile and external threads, featuring a stepped small hole at the top. Most likely the housing/plug of the pressure sensor, with a small hole at the top serving as the sensing‑medium passage, and a hexagonal threaded design ensuring a sealed connection to the equipment. Zhongzhong A straight-through part with a hexagonal outer profile and an internal bore, featuring external threads at both ends. Straight fittings for medical fluid tubing, with an internal bore serving as the fluid passage and threaded ends for pipeline connection; the hexagonal design facilitates installation and tightening. Upper right center Cylindrical part with external threads, featuring a locating pinhole at the base. Threaded connecting shafts/connectors for medical devices, with the threaded section used for assembly and fixation, and a small hole at the base serving as a positioning or locking feature. Bottom right center A stepped component with external threads and an internal bore, featuring mounting holes on the top. A connecting transition fitting for medical devices, with a threaded section for assembly and an internal bore/mounting hole at the top to accommodate sensors or other functional components. Bottom right Cylindrical part with an internal bore, without external threads. Most likely a bushing or sleeve component for medical equipment, with an internal bore designed to accommodate shaft-type parts and a cylindrical structure that provides support or sealing functionality. Right center Threaded part with multiple steps and an internal bore, featuring several mounting holes on the top. Complex medical connector/sensor base with a multi-step structure designed to accommodate the assembly of multiple components; the top mounting holes are used to secure the sensing element, while the threaded section ensures a sealed connection to the device. 3.
