Embodiment Construction

[0007] The medical oxygen concentration measuring device as shown in the figure includes the gas circuit connecting pipe 1, the gas circuit connecting pipe is a cylinder, the gas circuit connecting pipe is placed flat on the top of the cylinder surface, and the top of the cylinder is a rectangular surface, and a round hole is opened in the center of the rectangle to connect with the gas circuit connecting pipe Through, a buffer tube 2 is placed on the top of the gas path connecting pipe, and the rectangular surface communicates with the round hole. The tube is a cylinder, and one end of the measuring tube is an ultrasonic emitting and receiving device 5 and the other end is sealed with a cover sheet 4 . All materials are made of lightweight aluminum alloy.

[0008] There is a circular hole in the center of the rectangular surface on the cylinder surface of the gas path connecting pipe 1, and the two ends are cylindrical, and one side of the two circular surfaces is large and t...

Abstract

The invention discloses a device for measuring concentration of medical oxygen. The device comprises a cylindrical gas circuit connection pipe; the top part of a horizontally placed cylinder surface of the gas circuit connection pipe is a rectangular surface; the center of a rectangle is provided with a round hole, and is communicated with the gas circuit connection pipe; a buffer pipe is arranged on the rectangular surface at the top of the gas circuit connection pipe, and is communicated with the round hole; the buffer pipe is a vertically placed cylinder and is communicated with the gas circuit connection pipe; the top of the vertically placed buffer pipe is communicated with a gas concentration measurement pipe which is a cylinder; the lower part of the cylinder surface of the gas measurement pipe is a rectangular surface; the center of the rectangular surface at the lower part of the buffer pipe is provided with a round hole, and is communicated with the gas circuit connection pipe through the buffer pipe; the whole materials are prepared by adopting light aluminum alloy; the gas circuit connection pipe is used for being connected with the measured gas; the gas is ensured to disperse to the measurement pipe after the gas circuit connection pipe is connected with the gas, thus the gas concentration can be measured in the measurement pipe; an ultrasonic transmitter arranged in measurement pipe is used for transmitting and receiving ultrasonic signals which can be sent to a self-control circuit board through wires; signals are operated according to the different oxygen concentrations and different transmission speeds by the ultrasonic wave, and the signals are transmitted to a display after being processed, at this time, the corresponding oxygen concentration value can be observed on the display.

Description

technical field [0001] The invention belongs to medical equipment, in particular to an ultrasonic wave measuring oxygen concentration device. Background technique [0002] The main function of oxygen concentration sensors used in medical treatment is to monitor the inhaled oxygen concentration in ventilators and anesthesia machines. Most of them now use electrochemical principles, that is, oxygen batteries. However, the service life of the oxygen battery is relatively short, generally about one year. Adjusting the corresponding oxygen concentration according to the patient's condition can achieve different therapeutic effects. The ventilator and anesthesia machine used in the hospital are mostly imported equipment. The oxygen concentration battery is a consumable, which is expensive to replace and increases the medical cost of the hospital. Increased medical costs for patients. Contents of the invention [0003] The purpose of the present invention is to provide a non-co...
