The invention discloses an injector which comprises a barrel, a push rod, a piston, a pressure sensor, a treatment unit and a display unit, wherein the barrel is internally limited with a barrel cavity; the front end of the push end is inserted into the barrel cavity, and the back end of the push rod is backwards extended from the barrel cavity; the piston is arranged at the front end of the push rod, so that the barrel cavity is divided into a first front cavity and a first back cavity, and the piston can move in the barrel cavity along with the push rod; the pressure sensor is arranged on the push rod for detecting the liquid pressure in the first front cavity; the treatment unit is connected with the pressure sensor for treating a fluid pressure signal detected by the pressure sensor to obtain the fluid pressure value in the first front cavity; and the display unit is connected with the treatment unit to display the pressure value. The injector of the embodiment can intuitively obtain the pressure of the gas injected by the injector, so that the injection can be fast and conveniently performed, the pressure of the injected gas can be guaranteed to be within a safe range, and the operation safety can be improved.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a syringe for injecting fluid. Background technique [0002] A syringe is a commonly used medical device that has a wide range of uses and can inject liquids and gases. For example, during general anesthesia for surgery, the anesthesiologist needs to inflate the tracheal intubation airbag or laryngeal mask after the tracheal intubation is inserted into the patient's trachea. Improper inflation operation will cause tracheal wear, aspiration and tracheal stenosis. Appropriate inflation needs Know the air pressure in the balloon of the endotracheal tube. Traditionally, an air pressure test device is added between the intubation balloon and the syringe, which is very inconvenient to use. Or do not need at all, operate by operator's feeling, inflation safety is poor, and patient's life is threatened. In addition, some syringes that inject liquids also need to know the injection pre...
