Description
Technical field
This utility model relates to a kind of medical nursing TD antireflux device, can be used for the clinical cares such as closed drainage of pleural cavity, intraperitoneal drainage, peritoneal dialysis, indwelling catheter, humidification bottle oxygen uptake.
Background technology
Common drainage system is primarily of drainage tube and drainage bottle (bag) two parts composition, under normal circumstances, drainage bottle (bag) is placed on the position lower than patient posture, can realize the liquid of discharging in patient body by the function of drainage tube water conservancy diversion to drainage bottle (bag), when patient is irritated or unconsciousness time and there is position chanP, or nursing staff is in transportation of patients process under the abnormal conditions such as careless manipulation, there will be the situation of drainage bottle (bag) higher than patient posture, cause liquid reflux in drainage bottle (bag) in patient body, consequently cause nosocomial infection, cause severe complication, so that threaten patient vitals.
Summary of the invention
The purpose of this utility model proposes a kind of medical nursing TD antireflux device for weak point existing in above-mentioned prior art just.This utility model, by increasing an antireflux device between drainage tube and drainage bottle (bag), can avoid the generation of reflux phenomenon under abnormal conditions, thus eliminates the reflux hidden danger in drain nursing process.
Main design thought of the present utility model is as follows:
Adopt the composition check valves such as deformation footpath round tube hole main leg with a tight waist, ring support, elastic threads and the ball that dams, under normal circumstances, main leg is axially in the state of roughly vertical, the gravity of ball and the elastic threads of damming pulling force upwards and lower ring stand support force upwards form dynamic balance, the ball that makes to dam is positioned on the lower ring stand of main leg, the main leg aperture of this position is greater than the bulb diameter that dams, and the liquid from top enters in drainage container by main leg, realizes normal drainage function, in abnormal cases, namely main leg's run-off the straight or lower end reflux liquid level arrive lower ring stand, or when the two occurs simultaneously, because the change of action of gravity direction or reflux liquid create buoyancy to lower ring stand and the ball that dams, or when the two coexists, dynamic balance is originally broken, according to Newton's law and Hooke's law, in order to reach new dynamic balance, elastic threads will reduce the pulling force of the ball that dams, elastic threads is shunk and pulls the ball that dams upwards to move in ring stand direction, when abnormal conditions reach a certain critical condition, the ball that dams is pulled to main leg's latus rectum and is less than the position of the ball external diameter that dams and pipeline is blocked by elastic threads, achieve the antireflux function under abnormal conditions.
Concrete technical measures of the present utility model are as follows:
