Problems solved by technology
However, the airbag type humidification pump relies on manual inflation to control the flow rate of the humidification fluid, and its sealing requirements are extremely high. If there is a little loss in the cavity, even if it is equipped with a flow rate display, a certain error will occur, and when the infusion gradually decreases, Due to the change of the pressure of the liquid storage bag, the flow rate of the humidification fluid will change, which is not conducive to the continuous and stable output of the humidification fluid

The invention discloses an airway dehumidifying pump, which comprises a piston cover, a medicine liquid tank, a movable piston, a micro-titration pump, a medicine liquid outlet and a driving control device, wherein the movable piston is arranged in the medicine liquid tank; one end of the medicine liquid tank is connected to the piston cover and the other end of the medicine liquid tank is connected to the micro-titration pump by virtue of a medicine liquid passage; the micro-titration pump is connected to the medicine liquid outlet and the driving control device by virtue of the medicine liquid passage; and by virtue of the driving control device, the micro-titration pump is controlled to implement titration at a preset titration speed, so that the movable piston is moved towards the other end of the medicine liquid tank as the amount of medicine liquid in the medicine liquid tank is decreased. According to the embodiment of the invention, the titration time and flow velocity of the medicine liquid can be accurately controlled, and long-time stable output can be achieved, so that the titration accuracy of the airway dehumidifying pump is enhanced.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to an airway humidification pump. Background technique [0002] In patients with tracheotomy, the upper airway is replaced by a catheter, which destroys the normal anatomical structure and physiological functions of the airway, loses the functions of heating, humidifying, filtering and coughing of the upper airway, and weakens the defense ability. If the humidification of the airway is not enough, it is easy to cause water loss in the lower respiratory tract, dry airway, inhibition or loss of ciliary movement, secretions become sticky, easy to form phlegm scab or blood scab, resulting in poor expectoration, Tracheal blockage and hypoxia can cause atelectasis and secondary lower respiratory tract infection, which can even be life-threatening in severe cases. [0003] At present, the airway humidification pump mainly relies on the inflation of the airbag to adjust the dripp...
