Auto Button Blood Lancets are designed to be activated by pressing a button, which eliminates the need for a separate puncture device or fingerstick. This design helps to minimize the risk of accidental needlestick injuries and reduces the amount of time required for blood sampling. The button is located at the top of the lancet, and when pressed, it activates the needle to quickly and easily obtain a blood sample.
The underwater chest drainage bottle is designed to create the water seal which permits drainage of air and fluid from the pleural space but does not allow air to reenter the chest. The bottle can be used as single collection bottle with water seal or can be use at two-bottle or three-bottle system as water seal bottle.
