This invention provides a multifunctional automated PICC catheter puncture auxiliary frame, belonging to the field of medical device technology. It includes a flat plate on which a measuring component is connected via a synchronization assembly. The measuring component measures the arm circumference of the optimal puncture area on the patient's arm. A partitioning component is also mounted on the flat plate to partition the puncture area of ​​the patient's arm. Finally, a clamping component is mounted on the flat plate to clamp and support the patient's loose skin. In this design, the flat plate serves as the basic load-bearing structure of the entire auxiliary frame, providing a platform for the installation and support of each functional component. When the patient's arm is placed on the flat plate for treatment, medical personnel do not need to use a probe, reducing their workload and improving treatment effectiveness.

The invention discloses a tonsil postoperative diet management system and method, and relates to the technical field of medical care, and the system comprises a front end, a rear end, a database, an image recognition module and an intelligent interaction module. All the parts collaboratively realize the following functions: a data management function, a system management function, an authority management function, an automatic recipe recommendation function, an image recognition function and an interactive forum function. The personalized diet recipe can be automatically recommended according to the basic information, the medical history, the number of postoperative days and the tonsil mucosa recovery condition of the patient, meanwhile, an interaction platform between a doctor and the patient is built, and the problems that existing clinical diet guidance is general, individuation is lacked and doctor-patient communication is inconvenient are solved.

This invention relates to the field of tissue engineering technology and discloses a multi-level oriented muscle repair scaffold made from chitin nanocrystals and its preparation method. The invention uses chitin derived from shrimp and crab shells as raw material to prepare chitin nanocrystals. Through steps such as preparing an aqueous suspension of chitin nanocrystals, ultrasonic dispersion, directional freezing to induce ice crystal orientation growth, freeze-drying to control ice crystal sublimation, and glutaraldehyde cross-linking fixation, a multi-level oriented scaffold with a macroscopic oriented pore structure and a microscopic oriented micro / nanofiber structure is prepared, with the chitin nanocrystals arranged along the orientation pore direction. This scaffold has a high specific surface area, can promote the orientation alignment and myogenic differentiation of C2C12 cells, and can be effectively used for the repair of volumetric muscle tissue loss. Furthermore, the preparation method is simple, requires low-end equipment, is inexpensive, and can be mass-produced.
