The application discloses a kind of intelligent walking aids, it is related to walking aid technical field, including vehicle body and the drive car and universal wheel of vehicle body bottom installation, vehicle body is connected with seat mechanism, driving assembly is installed on vehicle body, and support mechanism is connected on vehicle body;The application is a kind of intelligent walking aid, when user needs to rest or physical strength is not supported hand, electric push rod will push seat plate to rotate upwards, so as to facilitate user to sit down and rest, elastic belt has elasticity, play certain buffering effect, can avoid user physical strength to fall down when not supported, support rod will be along fixed column by chute sliding, to drive support rod to stretch out outward, the universal wheel of support rod bottom end will be contacted with ground, to play certain supporting effect, avoid when user sits, vehicle body is tilted back, so more stable, when user appears incontinence, can be actuated actuator block to the side frame of vehicle body is shielded, to protect the self-esteem of user.

This invention belongs to the field of medical device technology, and specifically relates to a three-stage dilatation balloon for preventing contrast agent leakage. Addressing the problem that existing three-stage dilatation balloons rupture when the operating pressure exceeds the rated burst pressure, resulting in the instantaneous leakage of high-pressure contrast agent into the patient's body, leading to embolism or tissue damage, the following solution is proposed: an outer balloon body, an inner balloon body, a mesh reinforcement layer, a sheath, and a decompression balloon. The inner balloon body is located inside the outer balloon body, and the ultimate expansion diameter of the outer balloon body is larger than that of the inner balloon body. Both are made of different polymer materials, ensuring that the outer balloon body remains intact and forms a leakage-proof barrier when the inner balloon body ruptures. A mesh reinforcement layer is sandwiched between the inner and outer balloon bodies, and the intersection points of the mesh reinforcement layer are discretely connected to the outer wall of the inner balloon body via micro-anchors. This invention achieves automatic emergency storage and manual aspiration and removal of the contrast agent after balloon rupture, solving the safety problem of contrast agent leakage after overpressure rupture of existing balloons.

The utility model discloses a kind of sorting unloading devices for peeling machine, including device base, the top surface of device base is provided with three chutes, the top of device base is equipped with fixed plate and moving plate, fixed plate is vertically fixed on the top surface of device base and is located in one end of chute, rotating sleeve pipe is rotatably connected on the opposite side of fixed plate and moving plate, copper wire winding roller is connected between fixed plate and moving plate located in middle portion.The utility model device is installed in the discharge port of peeling machine, after cable peeling, cable skin is wound on cable skin winding roller, copper wire is wound on copper wire winding roller, after starting motor, three winding rollers are driven to rotate, copper wire and cable skin after peeling can be collected respectively, during collecting process, cable is also pulled to a certain extent, peeling speed is accelerated, after collecting is completed, winding roller can be disassembled, processing efficiency is improved, the problem that copper wire and cable skin after peeling can be avoided to occur mutual winding.
