Methods of treatment using a gastrointestinal implant device removably anchored within an animal's gastrointestinal tract. For example, the implant device includes a collapsible anchor for anchoring the device coupled to a proximal end of a flexible sleeve. The implant device can be anchored within the stomach, within the pyloric orifice, and / or distal to the pylorus and extended into the duodenum. All partially-digested food, or chyme, exiting the stomach is funneled through the device. Methods of treatment include treating obesity by one or more of: limiting the absorption of nutrients within the duodenum; delaying the mixing of chyme with digestive enzymes; alter hormonal triggers; and providing negative feedback. Alternatively or in addition, the desired result includes treating a diseases, such as diabetes, or temporarily shielding a portion of the intestine to promote healing within the intestine.

The invention relates to improved means for preventing eversion and subsequent obstruction of thin-walled, floppy gastrointestinal liners implanted in the digestive tract of an animal. The implantable devices include an anchor adapted for attachment within a natural body lumen and a thin-walled, floppy sleeve open at both ends and defining a lumen therebetween. A substantial length of the sleeve has material characteristics that result in the sleeve being prone to eversion in the presence of retrograde pressures. Exemplary eversion-resistant features provide an increased stiffness and / or an increased friction coefficient between the anchor and the proximal end of the sleeve to resist eversion. In some embodiments, the eversion-resistant feature includes an anti-buckling element, such as a wire coupled along the substantial length of the sleeve.

The invention discloses an external-installed triggering type anti-sink device. The external-installed triggering type anti-sink device comprises a base body with a lifting rail for guiding; a multi-claw rotor and a special-shaped clamp are rotatably installed in the base body through a pin shaft, a transmission part and a braking part which are in an L shape are installed on the special-shaped clamp, and the ends, close to the pin shaft, of the transmission part and the braking part are connected together, and the other ends of the transmission part and the braking part extend towards a distant place; an arc-shaped balance weight is formed by hunching up of the inner side face of the transmission part, an upper limiting plate used for limiting upwards rotating of the special-shaped clamp is formed on the position, corresponding to the outer side face of the transmission part, of the base body, and a side limiting face used for limiting downwards rotating of the special-shaped clamp is formed on the position, corresponding to the outer side face of the braking part, of the base body; and when the multi-claw rotor rotates, claws make sliding-matched movement along an arc-shaped track of the arc-shaped balance weight so that the special-shaped clamp can be pushed to deflect, and when the special-shaped clamp deflects to the outer side face of the transmission part and abuts against the upper limiting plate, the outer side face of the braking part abuts against the claws of the multi-claw rotor and limit rotation of the multi-claw rotor. According to the external-installed triggering type anti-sink device, the structure is simple and compact, and safety and reliability are high.

The invention discloses a rope-breakage protection device for a mine large-angle man cable car. The device comprises capturing slideways arranged on the two sides of a roadway, wherein the capturing slideway is connected with a support wheel beam through a slideway hanger arranged on the outer side of a support wheel hanger; a capturing cross arm is arranged toward the outer side on the capturing slideway; a rope clip fixedly connected with a steel wire rope is fixedly connected with a bidirectional catching hook; the bidirectional catching hook is located above the capturing cross arm; and when the steel wire rope is broken, the bidirectional catching hook drops to the capturing slideway and hooks the capturing cross arm. The device disclosed by the invention can effectively prevent major casualty accident caused by the broken traction steel wire rope in the conveying process of the large-angle overhead man cable car, and thus eliminates potential safety hazard and meets the requirements of safety production.
