Description

Controllable three-way thoracic drainage tube

Technical Field

The utility model relates to medical equipment, in particular to a controllable three-way thoracic drainage tube.

Background

The thoracic drainage tube is an important medical instrument for discharging gas and collecting liquid in a thoracic cavity, and is widely applied to drainage of hemothorax, pneumothorax and empyema and recovery after thoracotomy; at present, a thoracic drainage tube used in a hospital is generally a tube with two ends, one end is placed in a thoracic cavity, and the other end is connected to a water-sealed bottle; the defects that in the treatment and recovery process, the thoracic water needs to be reserved or the medicine needs to be injected into the thoracic cavity, so that the drainage tube needs to be detached, the use is inconvenient due to repeated use, and the sterility of the drainage tube is difficult to maintain due to the fact that the drainage tube is in the air; the existing three-way drainage tube cannot be adjusted, so that the injection pipeline is easily exposed in the air and is difficult to keep sterile. For example, the chinese patent literature discloses a new type of water-sealed bottle, whose publication No. CN 211157576U. Comprises a water-sealed bottle, a drainage tube, a three-way pipe, a drainage bag and a water-sealed bottle bracket; a water seal bottle bracket is arranged on the outer side of the water seal bottle, a hook is respectively arranged on the left side and the right side of the water seal bottle bracket, the water seal bottle is communicated with one side of a three-way pipe through a drainage tube, the other interface of the three-way pipe is communicated with a thoracic drainage tube, the interfaces of the rest three-way pipe are communicated with a drainage bag through the drainage tube, and the height of the drainage tube on one side of the drainage bag is lower than that of the drainage tube at the end of the water seal bottle; however, the three-way pipe has the disadvantages that the injection pipe of the three-way pipe lacks certain protection, bacteria are easy to generate in the using process, and danger is possibly caused to patients.

Preferably, the drainage tube body is provided with a one-way valve at one side of the three-way valve close to the outlet section tube; in the using process, the water-sealed bottle is required to be kept at a low position all the time, and the liquid in the bottle is prevented from flowing backwards, so that the one side of the three-way valve close to the outlet section is provided with the one-way valve, the backflow cannot occur even if the water-sealed bottle is placed at a high position, and the potential safety hazard is prevented.

Preferably, the T-shaped hollow parts of the three-way valve are provided with limiting buckles at the extending positions of three sides; in the use, need change the correlation function of drainage tube through the position of adjustment regulating block, through setting up spacing buckle, when changing drainage tube work, provide certain limit function, prevent three way valve's spurious triggering.

Preferably, a negative pressure detection device is arranged between the one-way valve and the outlet section pipe of the drainage pipe body; the negative pressure device of the drainage bottle connected with the three-way pipe is guaranteed to work constantly in the using process and no air leakage occurs, so that the negative pressure detection device is arranged in the using process, and the internal pressure in the using process is guaranteed to be normal.

Preferably, the inlet section pipe is provided with an insertion opening at the position where the chest pipe is connected; the insertion opening is directly placed into the thoracic cavity without using a connection mode, so that the using steps are simplified, and the arrangement and the use are convenient.

Therefore, the utility model discloses following beneficial effect has: (1) the three-way valve is used for reserving water in the thoracic cavity or injecting medicine, the drainage tube does not need to be disassembled, and the use is convenient; (2) the pipeline is regulated by the regulating block, so that the pipeline is not directly contacted with the outside air and the sterility is kept; (3) the insertion opening is directly placed into the thoracic cavity without using a connection mode, so that the using steps are simplified, and the arrangement and the use are convenient.
