The invention provides cardiovascular stent nickel-titanium wire forming equipment. The forming equipment comprises a stepping motor I, a rotating disc, a wire feeding assembly mounting base, a wire feeding assembly, a stepping motor II and a shaping grinding tool, wherein a plurality of circles of circular truncated cone wire hooking columns are fixedly connected to the outer wall of the shapinggrinding tool; the wire feeding assembly comprises a wire feeding mechanical arm, a wire feeding needle, a wire feeding screw assembly, a first connecting base, a second connecting base, a wire feeding motor and a nickel-titanium wire mounting column, and the wire feeding screw assembly comprises a connecting sleeve, a spiral sliding way and a spiral baffle. Active, stable and smooth wire supply can be achieved, and the situations of hooking of wires and the like which are not conducive to production are avoided; by means of the wire feeding screw assembly, the spiral sliding way divides the nickel-titanium wires into strands of wires one by one, and wire winding is avoided; by means of hook plates and the circular truncated cone wire hooking columns, the nickel-titanium wires can slide downwards to the contact surface of the circular truncated cone wire hooking columns and the shaping grinding tool along the circular truncated cone wire hooking columns, the nickel-titanium wires makefull contact with the surface of the shaping grinding tool, and heat shaping is more sufficient.

The invention discloses a man-machine experimental data analysis method based on eye movement, heart rate variability and behaviors. The man-machine experimental data analysis method comprises the following steps: (1) collecting man-machine experimental data of eye movement, heart rate variability and behaviors; (2) expanding a sample data volume by using a gray model; (3) establishing an eye movement, heart rate variability and behavior analysis model and a comprehensive analysis model; (4) calculating a residual average value of man-machine experiment data; and (5) establishing error ranges [Z experiment-sigma experiment, Z experiment+sigma experiment] and [Z contrast-sigma contrast, Z contrast+sigma contrast] of the experimental group and the control group, obtaining an analysis conclusion according to the intersection condition of the two error ranges, finally obtaining the experience condition of a user for service design in the script task, and further judging the reasonability of the service design. The data analysis method provided by the invention provides an analysis method for performing quantitative processing on man-machine data in service design, can scientifically and accurately judge the reasonability of the service design, and avoids fuzziness and uncertainty of subjective judgment.

The invention discloses an artificial respiration device for nursing in the department of cardiology. The device comprises a tooth socket. The detection device comprises an air inlet thread, an air outlet thread port, a converging port, a pipe groove, a rectangular groove and a rotary column. An arc-shaped rod is connected with the middle of the upper end of the detection device. The upper end ofthe arc-shaped rod is connected with an airbag ball. The other end of an air inlet pipe is connected with an air blowing cover. The lower side of the detection device is connected with a liquid discharge pipe. An illuminating lamp and a light sensor are arranged in the detection device respectively. Feathers are connected with the inside detection device. Exhaled air is exhausted from an air outlet pipe through the pipe groove. The feathers in the rectangular groove rotate around the rotary column through an arc-shaped pipe. The light sensor can receive strong illumination of the illuminatinglamp. A valve in an oxygen pipe is opened, and oxygen is supplied to a patient in a matched mode when the patient inhales. The structure solves the problem that an existing oxygen supply device supplies oxygen all the time and cannot supply oxygen in cooperation with the respiratory rate of the patient.
