Abstract: Disclosed are various embodiments for an anti-reflux enema bag having a pulley restrictor that acts as a waterflow restrictor, where the enema bag is leakproof, easy-to-clean, and provides a steady flow of solution. An enema bag system includes an enema bag, a nozzle comprising a nozzle outlet, and an anti-reflux coupler positioned between the enema bag and the nozzle through which the solution passes from the enema bag to the nozzle outlet. The anti-reflux coupler comprises an inlet for receiving at least a portion of the solution from the enema bag; an outlet for expelling the solution into the nozzle; and a check valve configured to prevent reflux of the solution from the nozzle. The enema bag system further comprises a pulley restrictor configured to selectively control a speed at which the solution is introduced into the nozzle and expelled from the nozzle outlet.

Abstract: Disclosed are various embodiments for an anti-reflux nasal aspirator that includes a nozzle comprising a nozzle outlet, a bulb configured to provide suction at the nozzle outlet in response to a squeezing force applied to the bulb, an anti-reflux coupler positioned between the bulb and the nozzle through which air passes from the bulb to the nozzle, and a one-way air valve positioned in an aperture located at a base of the bulb. The anti-reflux coupler may include a check valve configured to prevent reflux of debris into the bulb. The check valve may include one of an umbrella valve; a duckbill valve; a slit-cutting valve; and a flapper valve.

Abstract: Disclosed are various embodiments for an anti-reflux enema bucket system that is leakproof, easy to disassemble and clean, prevents reflux, has components that can be independently cleaned and sanitized, and controls a rate at which water is expelled from a nozzle outlet. In various embodiments, the enema bucket system includes an enema bucket having an opening at a top for filling the enema bucket with solution, a nozzle comprising a nozzle outlet, an anti-reflux coupler positioned between the enema bucket and the nozzle through which the solution passes from the enema bucket to the nozzle outlet; and tubing fluidly coupling the enema bucket, the anti-reflux coupler, and the nozzle. A pulley restrictor may selectively control a speed at which the solution is introduced into the nozzle and expelled from the nozzle outlet.

Abstract: Some embodiments of the present disclosure provide an energy-absorbing anti-creeper and a train vehicle with the energy-absorbing anti-creeper. The energy-absorbing anti-creeper includes: a guiding cylinder, an energy-absorbing material, a collision mechanism and a discharging mechanism for discharging the energy-absorbing material being arranged at the first end of the guiding cylinder. A first end of the guiding cylinder is configured to be in assembly connection with a train. The energy-absorbing material is filled in the guiding cylinder. The collision mechanism is arranged at a second end of the guiding cylinder. The first end of the guiding cylinder and the second end of the guiding cylinder are two opposite ends of the guiding cylinder.

Abstract: The invention relates to a method for connecting a connection piece to a U-shaped ring anchor for a head module for rail vehicles, the head module consisting predominantly of fiber-reinforced plastic material and having an outer shell and the ring anchor consisting of fiber-reinforced plastic material and being arranged in the roof region of the outer shell as a stiffening means. According to the method, connecting elements are fed through the dry or matrix-material-impregnated, unconsolidated fiber reinforcement structure of the ring anchor.
