Automatic water adding and dry burning preventing device for humidifier of breathing machine

Abstract

The invention discloses an automatic water adding and dry burning preventing device for a humidifier of a breathing machine. The device comprises a heat conduction silica gel pad, a pressure sensor arranged on the heat conduction silica gel pad, an annular support, a limiting foot plate arranged on the edge of the support, a vertical rod vertically arranged on the support, a transverse plate connected to the upper end of the vertical rod, a tension sensor hung on the transverse plate, and a hook connected to the tension sensor. The electric water stopping clamp is connected to the vertical rod and used for controlling the water adding pipeline to be connected and disconnected, the LED indicating lamp is connected with the vertical rod through a supporting plate, and the controller is connected to the vertical rod. According to the automatic water adding and dry burning preventing device for the humidifier of the breathing machine, the pressure sensor arranged on the heat conduction silica gel pad is used for detecting the pressure applied by the humidifier, automatic water adding of the humidifier can be achieved, and the workload of medical staff can be reduced; and in addition, the humidifier can be lifted up to be separated from the heater when the humidifier lacks water, and the dry burning condition can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anti-dry burning device of a ventilator humidifier. Background technique [0002] When a patient uses a ventilator to replace spontaneous ventilation, the gas output from the ventilator needs to be sent into a humidifier to humidify and warm the dry air to prevent the patient from inhaling dry, low-temperature gas for a long time to damage the respiratory tract. [0003] Attached to the manual figure 1 As shown, the humidifier 1 of the existing ventilator is generally placed directly on the heating plate of the heater 2, and the sterile water in the humidifier is heated by the heater. The existing ventilator humidifier has the following disadvantages in the working process: [0004] 1. The humidifier does not have automatic water replenishment function. In the actual work process, after the water level in the humidifier drops to a certain level, sterile water ne...
