Abstract

The utility model relates to an improved drainage tube for thoracic cavity, belonging to a drainage apparatus for pneumothorax clinical treatment. The drainage tube is of curved shape and is provided with a fixing clip, the surface of the drainage tube is provided with an air bag, the drainage tube is implanted into the thoracic cavity, and the drainage tube is connected with an inflation tube through an airway which is embedded into the drainage tube. Thereby, the internal and external fixations are effectively completed. The drainage tube is arranged between the lung and the chest wall, can rotate, has a favorable directivity, and has little possibility of blockage. The utility model has the advantages of reasonable structure, convenient manufacture, convenient operation, small pains of patients, and satisfactory clinic effects.

Description

Drainage tube for thoracic cavity

This utility model relates to a kind of treatment pneumothorax intrathoracic drain, belongs to the improvement to clinical inside and outside section treatment pneumothorax drainage apparatus.

Hospital clinical contacts a large amount of pneumothorax patients, adopts chest drainage, and method is simple, and very effective.Yet owing to finish the deficiency that the drainage tube of this treatment exists, to such an extent as to cause mediastinal emphysema more of empyema, in addition dead.Be embodied in: (1) is stayed in the drainage tube part of outside and can't be fixed, and sews up trouble, and rubber plaster is bonding, easily causes allergy again, and limits and breathe, in case deviate from, subcutaneous emphysema takes place easily, and need be reentered into, and then infects easily.(2) thoracic wall thickness can't be determined, the expanded influence of lung of the drainage tube after the puncture is pressed from both sides wherein, easily stop up, and non-directional.

This utility model purpose is by architecture advances, thereby makes it more completely effectively overcome above-mentioned defective.

This utility model adopts following scheme to realize: existing with having apical pore, side opening on the drainage tube, be beneficial to the drain of gas, liquid, other has a tip metal inner core and drainage tube to be used to complete puncture drainage together, on this basis drainage tube is made an angle of bend, can be free between lung and the thoracic wall after making drainage tube implant the thoracic cavity, and rotatable, have good directivity; Also be provided with fixing card on the drainage tube, can slide along the drainage tube surface, to finish the external fixation of thoracic wall; The drainage tube surface of implanting the thoracic cavity is provided with an air bag, and links to each other with aerating device outside the thoracic cavity by the air flue that is embedded in the drainage tube, and the inflation rear gasbag is finished internal fixation.

This utility model advantage is: (1) uses tip metal inner core, operation easily, and (2) are inside and outside fixing, can prevent from, subcutaneous emphysema, allergy and be difficult for stopping up, implant free the suspending of drainage tube in thoracic cavity, and rotatable, directivity is arranged, drain rapidly.

Fig. 1 is this utility model each several part structural representation.

Fig. 2 is that this utility model uses sketch map.

The utility model is described in further detail below in conjunction with accompanying drawing: drainage tube (1) adopts medical silica-gel or plastic production, and flexibility, histocompatibility are good.Drainage tube (1) is long for about 15cm, external diameter 1.4cm, the pipe of internal diameter 1.0cm, its front end accounts for 1/3 of length, the rear end is 2/3, the about 130 degree angles of angle of bend, and front end has an apical pore (2), two side openings (3), apart from front end 2cm place inflatable bladder (4) is arranged, around drainage tube (1), inflation back diameter can reach 4cm, width 1.5-2cm, air flue (5) is embedded in drainage tube (1) tube wall, and air flue (5) two ends link to each other with balloon (6) with air bag (4) respectively, and external fixation adopts dipteron shape fixed cover (7), can entangle drainage tube (1), slide up and down.

During use, tip metal inner core (8) inserts drainage tube (1), and is linearly, extracts inner core (8) after the puncture, drainage tube (1) bending, and its front end rotates finishes drain.Air bag (4) inflation then can be finished internal fixation, is slided along drainage tube (1) surface by dipteron shape fixed cover (7) and finish external fixation in the outside, thoracic cavity.

Claims

1, a kind of treatment pneumothorax intrathoracic drain, comprise (1) band apical pore, the drainage tube of side opening, be beneficial to gas, the drain of liquid, (2) establish the tip metal inner core that can take out in the drainage tube, to finish puncture and mediation drainage tube, it is characterized in that (3) drainage tube is an angle of bend, to guarantee that the drainage tube of implanting the thoracic cavity is free between lung and the thoracic wall, and have directivity, (4) drainage tube is provided with fixing card, can slide along the drainage tube surface, to finish the thoracic cavity external fixation, (5) the drainage tube surface in implantation thoracic cavity is provided with an air bag, and links to each other with aerating device outside the thoracic cavity by the air flue that is embedded in the drainage tube, finishes internal fixation after the inflation.
