Abstract

The invention discloses a directional automatic switching drainage device, and specifically relates to surgical drainage method for mechanical clinical application. The device is characterized in that a circular drainage tube is manufactured from rubber and other elastic materials; a connecting opening, which is namely a body fluid outlet in an outer section (1) of a drainage tube body and connected with a drainage bottle or a bag connecting tube (2), is designed to be a cone opening (3); a gap is formed from the surface of the cone opening (3) to the top of the cone, and the cone is divided into a plurality of arc surfaces (4) by the gap, wherein the quantity of the divided arc surfaces (4) can be determined according to the drained volume of fluid and the size of the tube. According to the device, the arc surfaces (4) of the cone opening (3) are separated as the hydraulic pressure increases during draining body fluid, and thus the body fluid can be drained smoothly; the hydraulic pressure decreases as the body fluid is drained, the arc surfaces (4) of the cone opening (3) can be quickly automatically closed, the cone opening (3) is closed as ever, and therefore, the outside fluid and germs can be prevented from entering; in a word, the opening is automatically closed as the hydraulic pressure increases and decreases during draining body fluid, thus the body fluid can flow outside in a fixed direction, and outside substrate can be prevented from entering; therefore, the defect of backflow and invasive infections of the current drainage tube caused by the change of the body, long placing and tube replacement can be completely solved, and reliable mechanical technical assurance is provided for speedy recovery of a patient.

Description

A kind of directed automatic interrupter drainage system

Technical field: belong to clinical medicine applied technical field, is specifically related to a kind of surgical drainage method for clinical medicine application.

Background technology: at present, the surgical drainage tube kind that clinical medicine is applied is a lot, have for urethral catheterization, have have application for wound, thoracic cavity, encephalocoele, gastrointestinal tract, drainage tube biliary tract etc.Surgical drainage, in order that be directed to external by the pus and blood gathered between tissue or in body cavity, liquid, prevent postoperative infection and affects wound healing.But when applying drainage tube, no matter straight pipe, Y-pipe, tee pipe or switching tube manually, all there are following three point defects: one is due to a variety of causes, cause the plane of position higher than patient's cannula port of drainage bottle (bag), cause adverse current to be polluted; Two is because intubation time is long, and pipeline leads directly in body, and the liquid that draws in drainage bottle (bag) grows pathogenic bacteria and by pipeline invasion body, can cause new infection; Three be because of medical personnel change drainage bottle (bag) time, sterilize not in place and cause extraneous pathogenic bacteria to invade, then entering in body from pipeline, causing new infection.Even if install hand switch on drainage tube, also can only be just can prevent from when closing flowing backwards and invasion, but above-mentioned defect cannot be overcome when normal drainage.

Summary of the invention: main purpose of the present invention is, provides a kind of directed automatic interrupter drainage system, to overcome the technical defect of the drainage tube that current clinical medicine adopts.By installing this directed recloser on drainage tube, above-mentioned three point defects can be overcome, not affecting again existing applied clinically drainage method.

Accompanying drawing illustrates: accompanying drawing is a kind of directed automatic interrupter drainage system figure.(1) external one section of drainage tube is represented; (2) connection tube of drainage bottle or bag is represented; (3) the cone mouth of pipe is represented; (4) cambered surface of cone decile is represented.

Detailed description of the invention: directed automatic interrupter drainage system, it is characterized in that: be the circular drainage pipe made by rubber elastomeric material, by the connection mouth of pipe of external for drainage tube one section (1) and drainage bottle or bag connection tube (2), i.e. body fluid outlet, be designed to the cone mouth of pipe (3), and have seam on the surface at the cone mouth of pipe (3), seam reaches the vertex of a cone always, and cone is divided into several cambered surface (4), decile cambered surface (4) number, can root Ju liquid displacement and pipe size and determine.Hydraulic pressure increase when utilizing body fluid to arrange outward allows the cone mouth of pipe (3) cambered surface (4) separately, and body fluid is discharged smoothly; Body fluid discharge after hydraulic pressure reduce, allow rapidly the cone mouth of pipe (3) cambered surface (4) automatically compound, the cone mouth of pipe (3) closed as before, stop in outer liquid and pathogenic bacteria enter.Namely use the increase and decrease of inside and outside discharge opeing hydraulic pressure automatically to close the mouth of pipe, directed outflow, stops a kind of drainage system entered in foreign object.Fundamentally solve current drainage tube because of position change, be long placed in, replace tubes cause flow backwards, defect that invasion is infected.Thus provide more reliable medical skill to ensure for patient's early recovery.

Claims

1. a directed automatic interrupter drainage system, it is characterized in that: the circular drainage pipe made by rubber elastomeric material, by the connection mouth of pipe of external for drainage tube one section (1) and drainage bottle or bag connection tube (2), i.e. body fluid outlet, be designed to the cone mouth of pipe (3), and have seam on the surface at the cone mouth of pipe (3), seam reaches the vertex of a cone always, and cone is divided into several cambered surface (4), decile cambered surface (4) number, can root Ju liquid displacement and pipe size and determine.Hydraulic pressure increase when utilizing body fluid to arrange outward allows the cone mouth of pipe (3) cambered surface (4) separately, and body fluid is discharged smoothly; Body fluid discharge after hydraulic pressure reduce, allow rapidly the cone mouth of pipe (3) cambered surface (4) automatically compound, the cone mouth of pipe (3) closed as before, stop in outer liquid and pathogenic bacteria enter.Namely use the increase and decrease of inside and outside discharge opeing hydraulic pressure automatically to close the mouth of pipe, directed outflow, stops a kind of drainage system entered in foreign object.
