The middle dropper is provided with an empty groove, and the size of the empty groove can be adjusted.
The intelligent pipe clamp is characterized in that the pipe clamp can be adjusted according to Murphy's droppers with different calibers, an infrared transmitting and receiving device and a built-in optical circuit are arranged in a pipe clamp groove, a rectangular display screen and a status lamp are arranged on the surface of the pipe clamp groove, the output end of the infrared transmitting device is connected with an optical circuit respectively, and the output end of the optical circuit is connected with the rectangular display screen.
Particularly, the utility model discloses a technical scheme do:
the utility model provides a portable venous transfusion tachymeter, by display screen, button, disposable battery dress check, pipe clamp, infrared ray perception appearance constitute its characterized in that: the shell that is located the tachymeter both ends meets with venous transfusion burette dead slot, display screen, button, disposable battery dress check, pipe clamp evenly distribute on the shell, set up the infrared ray perceptron that is used for surveing the speed that liquid drips in the pipe clamp inboard, the infrared ray perceptron with display screen, button are connected to signal data display that will perceive is in on the display screen.
According to portable venous transfusion tachymeter, its characterized in that: the infrared sensing instrument is internally provided with an infrared transmitting and receiving device which is connected with a photoelectric conversion device, converts an optical signal into an electrical signal, amplifies the electrical signal and displays the processed signal data on a display screen.
According to portable venous transfusion tachymeter, its characterized in that: and a state lamp is arranged between the infrared sensing instrument and the display screen, the velocimeter normally works as a continuous green lamp, and the velocimeter fails or is taken down to display as a continuous red lamp.
According to portable venous transfusion tachymeter, its characterized in that: the pipe clamp handle of the pipe clamp is concave-convex so as to be convenient to hold by hands.
According to portable venous transfusion tachymeter, its characterized in that: the display screen is a rectangular display screen.
According to portable venous transfusion tachymeter, its characterized in that: the casings at the two ends of the velocimeter are cuboid casings.
The utility model has the advantages that: the detector can be quickly and simply fixedly arranged on the infusion apparatus within a certain range. And the dropping speed can be calculated more accurately and conveniently.
