Abstract

The utility model discloses a universal thoracic indwelling drainage tube, which comprises a double-cavity guiding tube which has flexible elasticity and plasticity, wherein one cavity thereof is used as a flushing cavity, the other cavity is used as a drainage cavity, and the cross section of the flushing cavity is smaller than that of the drainage cavity. The front end of the double-cavity guiding tube is designed into a ring-shaped leading-in portion, and the rear end thereof is provided with a flushing bellmouthing which is communicated with the flushing cavity and a drainage bellmouthing which is communicated with the drainage cavity, the ring-shaped inner side of the leading-in portion is provided with a drainage hole which is communicated with the drainage cavity, and the ring-shaped outer side of the leading-in portion is provided with a flushing hole which is communicated with the flushing cavity. The universal thoracic indwelling drainage tube can share the drainage cavity and the flushing cavity simultaneously, can simultaneously drain and flush, and has complete drainage as the drainage cavity is large and is difficult to plug up. The bend head design of the drainage tube avoids damaging organs, and reduces stimulations and discomfort. The universal thoracic indwelling drainage tube has wide application range, is suitable for therapy of hydrothorax, hydropericardium and pyothorax, has low cost, and can repeatedly flush and drain once being indwelled in the thoracic cavity.

Description

General purpose type chest cavity indwelling drainage tube

Technical field

This utility model relates to medical apparatus and instruments.

Background technology

Have at present the patient of a large amount of hydrothorax, pericardial effusion and empyema in medical practice, especially the patients with lung cancer overwhelming majority has hydrothorax, and such disease is painful big, the treatment difficulty, and symptom is easily repeatedly.Traditional Therapeutic Method is repeatedly a liquid-pumping flush, injection.But need repeatedly puncture, exist misery big, the drawing liquid drain is not thorough, and recurrence is fast, the long and high shortcoming of expense of treatment cycle.

Present drawing liquid drain has dark venous indwelling pipe and pigtail conduit, and wherein dark venous indwelling pipe tube chamber is soft, is narrowed down by muscular tissue extruding on every side easily, and tube chamber is little to be organized by fragment and the sludged blood obstruction easily; The pigtail conduit is a single lumen catheter, and drainage treatment can not carry out simultaneously, need carry out repeatedly, uses inconvenience.

Summary of the invention

The purpose of this utility model provides a kind of general purpose type chest cavity indwelling drainage tube easy to use.

For achieving the above object, the technical solution of the utility model is as follows: it comprises that one has flexible resilient and plastic double channel catheter, and one of them chamber is the flushing chamber, and another chamber is a drainage lumens, and the section in flushing chamber is less than the section of drainage lumens; The front end of double channel catheter is processed into the introduction part of circle shape, and the rear end is provided with and washes flushing horn mouth that the chamber communicates and the drain horn mouth that communicates with drainage lumens; Circle inboard in introduction part is processed with the conduction hole that communicates with drainage lumens, is processed with in the circle of the introduction part outside and washes the flushing hole that the chamber communicates.

Using method of the present utility model is: determine point of puncture under B ultrasonic or X line perspective, use 2% lignocaine local anesthesia, use knife blade and do 0.3 centimetre of skin incision, to have the syringe puncture of puncture needle, after extracting hydrops out.Insert seal wire (60 centimetres of total lengths), withdraw from syringe, use expansion sheath expansion thoracic wall muscular tissue, withdraw from the expansion sheath, insert indwelling tube, withdraw from seal wire, external fixing (apply ointment or plaster paste or ligation is fixed) by seal wire.Fluid injection be can carry out after fixing simultaneously and drawing liquid drain, drug-injection in treatment cleaned.

As be used for tuberculous pleural effusion and vomica, and face be can carry out simultaneously and antibiotic and heparin flushing given continuously, reduce the pleural adhesion probability, avoid whole body to use the side effect that antibiotic brings.For example in a large amount of hydrops patients of pericardium, once keeping somewhere every day all can drain, and relief of symptoms can wash for infectious hydrops simultaneously rapidly, has reduced misery, has improved curative effect.

Now this kind product not still on the market has wide range of applications, and has the excellent popularization using value.

The utlity model has following advantage: 1, double lumen tube drain and flushing respectively have tube chamber, can carry out simultaneously.2, drainage lumens is big, is difficult for stopping up, and drain is more thorough.3, be easy to fix, can put for a long time and stay.4, crooked head design avoids damaging internal organs, reduces the zest discomfort.5, have wide range of applications, be applicable to hydrothorax, the treatment of pericardial effusion and empyema.6, cost is low, once inserts irrigation and drainage repeatedly.

Marginal data: 1-drain horn mouth, 2-washes horn mouth, and 3-washes the chamber, 4-drainage lumens, 5-flushing hole, 6-conduction hole, 7-circle shape introduction part.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, this utility model main body is one and has flexible resilient and plastic double channel catheter, and a chamber is flushing chamber 3, and another chamber is a drainage lumens 4, and the section in flushing chamber 3 is less than the section of drainage lumens 4.The front end of double channel catheter is processed with circle shape introduction part 7, the rear end is provided with and washes flushing horn mouth 2 that chamber 3 communicates and the drain horn mouth 1 that communicates with drainage lumens 4, and be processed with the conduction hole 6 that communicates with drainage lumens 4 in the circle inboard of introduction part 7, be processed with in the circle outside of introduction part 7 and wash the flushing hole 5 that chamber 3 communicates.

Claims

1, a kind of general purpose type chest cavity indwelling drainage tube is characterized in that, it comprises that one has flexible resilient and plastic double channel catheter, and one of them chamber is the flushing chamber, and another chamber is a drainage lumens, and the section in flushing chamber is less than the section of drainage lumens; The front end of double channel catheter is processed into the introduction part of circle shape, and the rear end is provided with and washes flushing horn mouth that the chamber communicates and the drain horn mouth that communicates with drainage lumens; Circle inboard in introduction part is processed with the conduction hole that communicates with drainage lumens, is processed with in the circle of the introduction part outside and washes the flushing hole that the chamber communicates.
