A cricothyrotomy syringe has a hollow body, a needle connector at an end of the body, an aperture at an opposite end of the body, a plunger in the aperture, the plunger having a seal that forms a liquid tight seal with an inner surface of the body and the plunger moveable within the body between an extended position and a compressed position and a ventilator adaptor extending from a side of the body, where an interior of the ventilator adaptor is in fluid communication with an interior of the body when the plunger is in the extended position.

Cricothyrotomy device

A self-retaining retractor is described. The retractor can be sized for small patients, such as young children or infants or some animals. The retractor has two blades that are capable of holding tissue separated during a procedure, such as a tracheotomy.
