Abstract

A drainage lavaging device is mainly used for ascites drainage for puncturing, and comprises a T-shaped body, a needle, a knob, a fixing plate, a lavaging connector, a drainage connector, a valve core, a pressure cover and a spring. The fixing plate which is used for adhesion fixing is arranged on the upper portion of the body, the needle is mounted at the center of the fixing plate, the lower portion of the body is provided with the drainage connector, the lavaging connector is arranged on the right of the body, and a tee valve is arranged at the joint of the T shape of the body and structurally provided with a taper hole at the joint of the T shape of the body. The valve core and the spring are mounted in the taper hole, the pressure cover is screwed at an orifice of the taper hole to press the valve core and the spring into the taper hole, a shank of the valve core extends out of the pressure cover to be connected with the knob, and the rotating knob is capable of controlling the needle to be communicated with the lavaging connector or communicated with the drainage connector. The drainage lavaging device has the advantages of simplicity, practicality, easiness in operation and capability of continuously completing ascites sucking and lavaging once.

Description

A kind of drain lavage apparatus

Technical field

This utility model relates to the medical apparatus technical field, is specifically related to a kind of drain lavage apparatus, and it can be used for the puncture drainage seroperitoneum.

Background technology

Body fluid such as ascites and hydrothorax makes from blood vessel and intralymphatic and leaks into the free fluid that abdominal cavity and thoracic cavity accumulated form; When ascites and thoracic cavity often reach some; To cause compressing to human organ, even influence function of human body, particularly these ascites are owing to the time in body cavity is long very easily infected; In order to alleviate the infringement of ascites and hydrothorax, must it be treated human body.At present, take off mourning clothes outside the medicament for the treatment of ascites, the puncture drainage seroperitoneum also is a kind of efficient ways.Present domestic puncture drainage mostly utilizes the suction ascites of disposable syringe repeated multiple times; Then repeated multiple times with normal saline lavation abdominal cavity, this is simple and practical with method, but its shortcoming is suction of this repeated multiple times and lavation; Cause infection easily, cause the patient through regular meeting and have a low fever.Traditional on the other hand puncture needle also exists and is difficult for fixed shortcoming.

Summary of the invention

The purpose of this utility model is to remedy the defective and the deficiency of prior art, and a kind of drain lavage apparatus is provided, and it is simple and practical, easy operating, and reliable operation can be accomplished suction and lavation work and easy fixation by one-time puncture continuously.

For realizing above-mentioned purpose, this utility model adopts following technical scheme: a kind of drain lavage apparatus comprises main body, syringe needle, knob, fixed disk, lavation joint, flow sub, spool, gland, spring; Said main body is injection molded by polypropylene; Its profile is a T-shaped, and the top of main body is provided with a fixed disk that is used to be adhesively fixed, and a syringe needle is housed in the center of fixed disk; The bottom of main body is provided with a flow sub; The right part of main body is provided with a lavation joint, and three ramose endoporus of T-shaped main body connect each other, are provided with a three-way valve in the T-shaped intersection of main body; The structure of said three-way valve is for to be shaped on a taper hole in the T-shaped intersection of main body, and spool and spring are contained in the taper hole, and the place, aperture that gland is screwed in taper hole is pressed in spool and spring in the taper hole,, the shank of spool stretches out outside the gland and with knob and is connected.Thereby rotary knob can make spool rotation control syringe needle and lavation joint connect or connect with flow sub.

The method for using of this utility model: be plugged into the lavation flexible pipe of the drain flexible pipe of aspirator and douche respectively on flow sub and the lavation joint; Rotary knob connects syringe needle and flow sub; Aspirate ascites with aspirator; Then rotary knob connects syringe needle and lavation joint, in abdomen, pours into saline with douche, and repeatable operation is several all over accomplishing drain lavation work like this.

The beneficial effect of this utility model is: simple and practical, and easy operating, reliable operation, bonding firm, can one-time continuous accomplish ascites suction and lavation work.
