Chest drain that I Saw in HKL

I was introduced to a small chest drain called Pneumostat in HKL . . It's used for pneumothorax.

Air leaves the device's one-way valve through a vent that leads into an air leak well; If you want to check whether there's an air leak from the lung or not, you can add some water to the well...If it bubbles, means that there's an air leak. Its small size is convenient for patients to mobilize.

I didn't took a picture because I didn't plan to blog bout this initially...Haha...Hence, you cant imagine it's actual size...It's smaller than my hand if not mistaken...
