Description

T-type free fixation chest drainage tube

technical field

The invention relates to the field of medical equipment, in particular to a T-shaped chest drainage tube without fixation.

Background technique

Closed thoracic drainage after routine thoracic surgery (such as lobectomy, radical resection of esophageal cancer, etc.) has become routine and consensus. But the real problem is that thoracic surgery methods and related intraoperative measures have made great progress, but postoperative management (such as drainage tubes and urinary catheters, etc.) has not changed. The purpose of postoperative chest drainage tube is mainly to prevent pleural effusion or effusion and promote lung recruitment, so as to reduce related complications. In the past ten years, laparoscopic technology has been widely used in the field of thoracic surgery and has made significant progress, but 36F, 32F or 28F drainage tubes are still used for drainage after surgery. At present, everyone tends to 28F, 28FPVC drainage tube is helpful for postoperative lung recruitment. Existing models of chest drainage tubes are inserted during thoracic surgery or closed drainage, with a length of 4-5 cm. Traditional chest drainage tubes Since there is no fixed structure, it is necessary to indwell a preset wire at the incision to fix the drainage tube after operation, and the preset wire brings great discomfort to the patient, such as pain, movement disorder and delayed healing of the drainage tube orifice.

Contents of the invention

In view of the fact that the traditional chest drainage tube has no fixed structure, it is necessary to indwell a preset line at the incision to fix the drainage tube after operation, and provides a non-fixation chest drainage tube, which can be fixed without indwelling a preset line.

In order to achieve the above object, the technical scheme adopted in the invention is as follows:

The invention discloses a T-shaped chest drainage tube without fixation, which includes a main drainage tube and a branch drainage tube. There are two branch drainage tubes. The axes of the tubes are coincident, the cross-section of the branch drainage tube is semicircular, the front end of the main drainage tube is connected to the arc-shaped side wall of the branch drainage tube, the plane side wall of the branch drainage tube is perpendicular to the main drainage tube, and the plane side of the branch drainage tube Drainage holes are provided on the wall.

Preferably, the diameter of the circular tube formed after the plane side walls of the two branch drainage tubes are fitted together is the same as that of the main drainage tube.

Preferably, the lengths of the two branch drainage tubes are 4cm and 7cm respectively.

Preferably, the main drainage tube and branch drainage tubes are integrally manufactured.

Preferably, the materials of the main drainage tube and the branch drainage tubes are all PVC plastics.

Preferably, the branch drainage tube with a length of 4cm offers two drainage holes, and the two drainage holes are arranged axially along the branch drainage tube; the branch drainage tube with a length of 7cm offers three drainage holes, and the three drainage holes Arranged at equal intervals along the axial direction of the branch drainage tubes.

Preferably, the drainage holes are circular, square or oval.

Further, the rear end of the main drainage tube is connected with a negative pressure suction joint. .

The beneficial effects of the invention are as follows:

The invention utilizes the drainage tube placed in the chest cavity, which can be fixed without presetting the reserved line after the operation, relieves the patient's discomfort, relieves the postoperative pain, promotes lung recruitment, reduces pulmonary complications, and speeds up the postoperative recovery of patients undergoing thoracic surgery. recover.

Detailed ways

In order to make the purpose, technical solution and advantages of the invention clearer, the invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the T-shaped free-fixing chest drainage tube disclosed by the invention includes a main drainage tube 1 and a branch drainage tube 3, the rear end of the main drainage tube 1 is connected to a negative pressure suction joint, and there are two branch drainage tubes 3 , one end of the two branch drainage tubes 3 is connected to the front end of the main drainage tube 1, the axes of the two branch drainage tubes 3 coincide, the cross section of the branch drainage tube 3 is semicircular, and the front end of the main drainage tube 1 is connected to the branch drainage The arc-shaped side wall of the tube 3, the plane side wall of the branch drainage tube 3 is perpendicular to the main drainage tube 1, and the drainage hole 2 is set on the plane side wall of the branch drainage tube 3; the shape of the drainage hole 2 is circular, square or oval .

The diameter of the circular tube formed after the plane side walls of the two branch drainage tubes 3 are fitted together is the same as that of the main drainage tube 1 . The length of one of the branch drainage tubes 3 is 4cm, and two drainage holes 2 are arranged along the axial direction of the branch drainage tube 3; Arranged drainage holes 2.

During clinical application, after the invention is placed in the thoracic cavity, the 3 branches of the two-branch drainage tube can withstand a force of 20-30N, and there is no need to leave a preset line. Afterwards, the chest tube is pulled outward to ensure that the fixation is intact. When pulling out the chest drainage tube, pull it out with a strength greater than 20-30N, and the two branch drainage tubes 3 can close up into a circle with the same diameter as the main drainage tube 1 in cross section, which is convenient for extubation.

The same transformation can be carried out on existing models of chest drainage tubes, namely 16F, 18F, 20F, 22F, 24F, 26F, 28F, 32F, 36F and other models of chest drainage tubes.

Of course, the invention can also have other various embodiments. Without departing from the spirit and essence of the invention, those skilled in the art can make various corresponding changes and deformations according to the invention, but these corresponding changes and deformations are all It should belong to the scope of protection of the appended claims of the invention.
