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 provides a multifunctional pleuroperitoneal cavity irrigation and suction device, which relates to the technical field of medical instruments and comprises a handle operation assembly, an irrigation and suction assembly and a water outlet mode knob assembly. A micro electric heater is arranged in the handle operation assembly and is used for heating the washing liquid; the flushing and suction assembly is detachably connected with the handle operation assembly and comprises a tube body with a hollow cavity and an ablation electrode arranged in the tube body, the flushing and suction assembly further comprises a pull button, and a pressure spring is arranged in the pull button and used for enabling the ablation electrode to retract into the tube body in a non-operation state; the water outlet mode knob assembly is arranged at the water outlet end of the flushing and suction assembly and comprises an inner ring piece and an outer ring piece, and a common water outlet mode, a mist water outlet mode and a jet water outlet mode are achieved through relative rotation of the inner ring piece and the outer ring piece. Residues at the surgical site can be effectively removed, all-directional flushing is achieved, the adverse effect of the temperature of flushing fluid on the surgery is avoided through constant-temperature control, and the surgical safety and the postoperative recovery effect are improved.

The present invention improves the nursing of a patient after a necessary operation on a lesion site from a puncture site such as a radial artery. A medical system (1) according to one embodiment of the present invention is provided with: an acquisition unit (20) that acquires a plurality of pieces of biological information relating to the state of a patient who has received a puncture surgery from an upper limb artery; a control unit (50) capable of adjusting a compression method for stopping bleeding of the patient on the basis of a plurality of pieces of biological information relating to the state of the patient acquired from the acquisition unit; and a notification unit (30) capable of notifying an intervention method based on the biological information.

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.
