Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, in an embodiment of the present invention, a thoracic drainage tube includes a tube 1, the tube 1 having a proximal end near a thoracic cavity and a distal end away from the thoracic cavity.

Specifically, swing joint has fixing device 4 on the near-end outer wall of body 1, and this fixing device is the annular, and the material can be rigid plastic or carbide, and the adjustable distance with the thorax of this fixing device is convenient for the ligature sew up the stylolite that incision department reserved, plays the effect of fixed drainage tube.

Specifically, the distal end inside of body 1 sets firmly prevents palirrhea valve 2 of liquid, and this valve is the gravity check valve, and this valve is placed at the drainage tube distal end that is less than the thorax position, and when patient's activity of getting up carelessly resulted in drainage tube distal end position to be higher than drainage tube near-end position, the gravity check valve is automatic closed, can not only effectively avoid the palirrhea condition of liquid to cause the infection, and thoracic cavity liquid can accelerate the outflow because of patient's activity moreover, promotes the lung and opens again.

Specifically, a drug administration flushing pipe 3 is arranged in the pipe body 1, the drug administration flushing pipe comprises a drug administration flushing pipe body located in an inner cavity of the pipe body 1 and a drug administration port 31 used for being externally connected with a drug administration flushing device, and the drug administration port 31 penetrates out of the pipe wall and is located outside the far end of the pipe body 1. The administration flushing and the drainage are carried out by two cavities, so that the risk of infection caused by the use of the same cavity for drainage and flushing administration is effectively avoided.

Specifically, the tube wall of the tube body 1 is connected with a flow stopping clip 5 which is a Robert clip, the Robert clip is sleeved on the drainage tube, the Robert clip is in an open state during drainage, and the drainage is not blocked; when the patient moves, the Robert clamp is adjusted to be in a closed state, and at the moment, the liquid cannot flow, so that the trouble that the patient needs to additionally use a hemostatic clamp to clamp the tube when going out for examination and movement is avoided, and the Robert clamp is simple, convenient and easy to operate.

Specifically, be equipped with a pjncture needle 6 in body 1, the most advanced of pjncture needle is worn out the outside of body 1 near-end, the drainage tube that has the pjncture needle can make things convenient for the doctor to simplify the operating procedure, has improved the convenience of drainage operation, has also alleviateed the misery in the patient's operation simultaneously.

Furthermore, the utility model discloses possess the common characteristic of current drainage tube: the tube body 1 is made of soft silica gel, so that the internal organs of a patient cannot be punctured, and the pain of the patient can be relieved; the near end of the tube body 1 is provided with at least one drainage hole for drainage; be equipped with even scale mark on the outer wall of body 1, make things convenient for the art person to judge the inserted degree of depth from the scale mark.

The utility model discloses place the thorax incision with drainage tube one end when using in, the drainage bag lower than its position is connected to the other end to exhaust gas or collect the liquid in the thorax, make the lung tissue open again and resume the function. In order to facilitate the clinical operation, as shown in fig. 1-2, the outer wall of the proximal end of the tube body 1 near the thoracic cavity is provided with a fixing ring, and the operator can use a plurality of reserved sutures to tie the fixing ring when suturing the incision, so as to prevent the drainage tube from falling off. In addition, the fixing ring can also be used for facilitating binding operation by adjusting the distance from the position of the thoracic cavity. The far end inside of body 1 far away from the thorax sets firmly prevents palirrhea gravity check valve 2 of liquid, and this valve is placed in the drainage tube distal end that is less than the thorax position, and when patient's activity of getting up carelessly leads to drainage tube distal end position to be higher than drainage tube near-end position, gravity check valve is automatic closed. The tube wall of the tube body 1 is connected with a flow stopping clip 5 (shown in figure 2), the flow stopping clip is a Robert clip, the Robert clip is sleeved on the drainage tube, the Robert clip is opened in a drainage state, and effusion flows out unimpeded; when the patient moves, the Robert clamp needs to be adjusted to be in a closed state, and at the moment, liquid cannot flow. The interior of the tube body 1 is also provided with a puncture needle 6 which can penetrate through the tube body 1 to puncture the thoracic cavity from the far end of the tube body 1.
