The invention relates to the technical field of
fascia pressure measuring instruments, in particular to a disposable automatic
fascia pressure
measuring instrument which comprises a
measuring instrument shell, a control mechanism is fixedly connected to the bottom end of the interior of the
measuring instrument shell, a suction mechanism is fixedly connected to one side of the interior of the measuring instrument shell, and an injection mechanism is installed on the other side of the interior of the measuring instrument shell. When air in the
fascia chamber is evacuated, in order to inject normal
saline and monitor the pressure in the fascia chamber, a first gear is driven to rotate through rotation of a first motor, so that the first gear is conveniently driven to rotate in the rotating process, and the normal
saline is injected into the fascia chamber; and a first gear rotates to be meshed with a first gear rack, so that a first push rod at one end of the first gear rack is driven to be pulled, the first push rod drives a first
piston to be pulled in a suction cylinder, and the suction cylinder pumps out air in a fascia chamber through a first conveying
pipe.
