Description

Pneumothorax puncture guiding and positioning device for department of respiration

Technical Field

The invention relates to the technical field of medical instruments, in particular to a thoracentesis guiding and positioning device for a respiratory department.

Background

Thoracentesis refers to the operation of puncturing the skin, intercostal tissues, parietal pleura and entering the pleural cavity with a sterilized needle. In the clinical work of the pneumology department, thoracentesis is a common and convenient and simple diagnosis and treatment method. If through inspection, find that there is hydrops in patient's pleural cavity, can draw liquid through the thoracentesis, carry out various inspections, find out the cause of disease.

In the clinical work of the pneumology department, thoracentesis is a common and convenient and simple diagnosis and treatment method. Such as: through inspection, we find that there is effusion in the pleural cavity of a patient, and can extract liquid through thoracentesis, carry out various inspections, find out the cause of disease. If the cavity accumulates much liquid, the lung is pressed or the liquid accumulation time is too long, fibrin in the cavity is easy to organize and generate two layers of pleural adhesions, so that the respiratory function of the lung is influenced, and then the accumulated liquid is also needed to be drawn out by puncturing. If necessary, the medicine can be injected to achieve the purpose of treatment. If too much gas is present in the pleural cavity and the pleural cavity has been changed from negative to positive pressure, then the gas can also be evacuated by reducing the pressure in this operation.

The thorax puncture device that has now adopts artifical puncture or auxiliary positioning device to carry out the puncture operation in coordination in the use more, but at the actual operation in-process, because of patient's fat layer thickness differs and the selection of puncture position is different, need the manual work to carry out the accuse of the depth of puncture, nevertheless apply sometimes can be because the depth of puncture is inaccurate or other reasons to the accuse, cause the depth of puncture not enough, need the secondary to carry out the puncture deeply, or the depth of puncture is too deep influences normal puncture effect, both can increase medical staff's the operation degree of difficulty, increase patient's pain.
