The closed thoracic cavity drainage tube comprises an inlet tube, a three-way valve, a side tube, an outlet tube and a valve shell, wherein the three-way valve is installed inside the valve shell; a first port, a second port and a third port of the three-way valve penetrate through the valve shell; the inlet tube is installed at the first port of the three-way valve; the outlet tube is installed at the second port of the three-way valve; the side tube is installed at the third port of the three-way valve; and the three-way valve is installed inside the valve shell. The closed thoracic cavity drainage tube is used for thoracic cavity drainage.
Description
Technical field
This utility model relates to a kind of intrathoracic drain, belongs to technical field of medical instruments.
Background technology
As everyone knows, pneumothorax, liquid breast or hydropneumothorax need carry out the chest drainage treatment.Mostly existing drainage system is to be made up of drainage tube and water-sealed drainage bottle, at first will perform the operation in the use to put pipe or trocar puncturing is put pipe, and suture is fixed or foley's tube is fixed again, and is last, connects the water-sealed drainage bottle closed drainage.Existing drainage tube in use can't be avoided the air into thoracic cavity of escaping fully, is prone to cause thoracic cavity infection.
The utility model content
The purpose of this utility model is in use can't avoid the air into thoracic cavity of escaping fully in order to solve existing drainage tube, is prone to cause the problem of thoracic cavity infection, and then a kind of closed thoracic drainage tube is provided.
The technical scheme of this utility model is: closed thoracic drainage tube comprises inlet pipe, three-way valve, side pipe, goes out pipe and valve casing; Three-way valve is installed in the valve casing; First port of three-way valve, second port and the 3rd port all pass valve casing; First port and second port are symmetrical set, and inlet pipe is installed in first port of three-way valve, go out second port that pipe is installed in three-way valve; Side pipe is installed in the 3rd port of three-way valve, and three-way valve is installed in the valve casing.
This utility model compared with prior art has following effect: the closed thoracic drainage tube of this utility model has easy and simple to handle and safe and reliable advantage; Can avoid the air into thoracic cavity of escaping fully; Eliminate the drawback of thoracic cavity infection, and the lavation in the operation or injection need not puncture, stopped infection.
Description of drawings
Fig. 1 is the structural representation of the closed thoracic drainage tube of this utility model, and Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The specific embodiment one: combine Fig. 1 and Fig. 2 that this embodiment is described; The closed thoracic drainage tube of this embodiment comprises inlet pipe 1, three-way valve 2, side pipe 3, goes out pipe 4 and valve casing 5; Three-way valve 2 is installed in the valve casing 5, and the first port 2-1 of three-way valve 2, the second port 2-2 and the 3rd port 2-3 all pass valve casing 5, the first port 2-1 and the second port 2-2 is symmetrical set; Inlet pipe 1 is installed in the first port 2-1 place of three-way valve 2; Go out the second port 2-2 place that pipe 4 is installed in three-way valve 2, side pipe 3 is installed in the 3rd port 2-3 place of three-way valve 2, and three-way valve 2 is installed in the valve casing 5.
When this utility model used, with the end insertion thoracic cavity of inlet pipe 1, an end that goes out pipe 4 was connected with drainage bottle, at this moment, kept two logical operations, and liquid in the thoracic cavity is entered drainage bottle; When moving patient or replacing, when toppling over drainage bottle, three-way valve 2 being closed; When lavation of need thoracic cavity or injection, earlier transfusion device is connected with side pipe 3, close at the second port 2-2 three-way valve 2, can operate, avoided puncture to the misery that the patient brings, guaranteed the safety in the operation simultaneously, symptoms such as infection can not appear.
