Abstract

The utility model belongs to a medical appliance, particularly relating to spiral intrathoracic drain which is suitable for surgery clinical use. The spiral intrathoracic drain of the utility model is formed by that certain length of the tube wall on the insertion end of a silicon plastic tube used for drainage is removed according to screw method and equidistance. The drain without the tube wall forms a mutually spiral and parallel open structure with the left tube wall, and the end of the reserved screw tube wall is in the shape of semicircle or semiellipse. Because the insertion end of the utility model is the spiral open structure and has favorable soft performance, the utility model solves the defects that the traditional drain is easy to stimulate the patient's chest viscera and easy to block and the drainage is inexhaustible. The utility model has the advantages of simple structure, and easy use.

Description

Spiral intrathoracic drain

This utility model belongs to a kind of medical apparatus and instruments, especially relates to the spiral intrathoracic drain that a kind of surgical clinical uses.

The intrathoracic drain of present clinical use is end, side-hole-type silica gel tube, and it is simple in structure, is easy to processing.But also there is following deficiency: the one, because its elasticity, hardness are bigger, place and do not note slightly, its top easily stimulates organs such as patient's heart, lungs: the 2nd, and end, side opening are often stopped up by clot, fibrous tissue, be difficult for mediation, cause patient thoracic cavity, mediastinum, intrapericardial liquid, gas to gather, jeopardize patient's life.

Of the present utility modelly openly be intended to not stimulate internal organs in the thoracic cavity for the thoracic cavity postoperative patient provides a kind of, guarantee the not blocked unobstructed a kind of intrathoracic drain that has helical structure of drain that makes of drainage tube chamber.

A kind of spiral intrathoracic drain is made up of the flexible pipe that has drainage tube chamber 3, it is characterized in that: the open helical structure of one end for being made of flight 1 and gap between screw 2.

According to above-described a kind of spiral intrathoracic drain, its feature also is: the end of flight 1 is semicircle shape or semiellipse shape.

Accompanying drawing is spiral intrathoracic drain structural representation, wherein:

Fig. 1 is spiral intrathoracic drain structural representation, wherein:

1--flight 2--gap between screw 3--drainage tube chamber

In conjunction with the accompanying drawings, the implementation procedure of narration this utility model spiral intrathoracic drain: the spiral chest drainage tubular construction of this utility model, processing are very simple, select one of the suitable medical drainage flexible pipe of a length, internal diameter, wall thickness for use, begin the tube wall of the certain distance of drain flexible pipe is removed by spiral way is equidistant from one port, the space of removing on the drainage tube behind the tube wall is a gap between screw 2, tube wall that stay, between the gap between screw 2 is a flight 1, and the end of flight 1 is semicircle shape or semiellipse shape.The end of the flight 1 of semicircle shape or semiellipse shape is the insertion end of this drainage tube.

Embodiment:

Intercepting external diameter 12mm, wall thickness 1.5mm, length is the medical silicon plastic cement Guan Yigen of 400mm, draw the spiral parallel lines that distance is respectively 10mm, 7mm from one end end to the other end, parallel lines are drawn from its end and are begun to its 60-80mm, remove with blade or the shears part that 7mm in the helix is wide, the shape space of removing on the drainage tube behind the tube wall of revolving is a gap between screw 2, helical form tube wall that stay, between the gap between screw 2 is a flight 1, wedge angle with flight 1 end removes at last, makes it to become semicircle shape or semiellipse shape.This end drainage tube that has flight 1 and gap between screw 2 is the open helicoidal structure of 360 degree.The end of the flight 1 of semicircle shape or semiellipse shape is the insertion end of this drainage tube.

Use:

The end of clamping this drainage tube flight 1 semicircle shape or semiellipse shape with operating forceps is inserted patient's draining hole and slowly is inserted into correct position and just can.

Effect and advantage:

By clinical use, effect is highly desirable, and it is embodied in:

1, because this drainage tube front end is the open helicoidal structures of 360 degree, and flexibility is strong, internal organs in cardiac stimulus and the thoracic cavity are not applicable to the drain of heart and thoracic cavity postoperative more.

2, comprehensive draining fluids, difficult by blood clot, fibrous tissue obstruction.Even obstruction is arranged, at external antispin direction rotation drainage tube it is come off, guarantee that tube chamber is unobstructed, increase the completeness of drain.

When 3, going closed thoracic drainage, its front end is easy to clamp, is convenient to place.

4, material is a silicon plastic cement pipe, and with low cost, it is simple in structure, is easy to produce and promote.

Claims

1, a kind of spiral intrathoracic drain is made up of the flexible pipe that has drainage tube chamber 3, it is characterized in that: the open helical structure of one end for being made of flight 1 and gap between screw 2.

2, a kind of spiral intrathoracic drain according to claim 1, its feature also is: the end of flight 1 is semicircle shape or semiellipse shape.
