Abstract:
Objective To design an exhalation valve reservior cup to solve the problems of removal of the condensate and prevention of aerosol diffusion.Methods The reservior cup was composed of a temporary storage bottle,a liquid collection bottle,a sealing mechanism and a connection mechanism.The temporary storage bottle was connected to the exhalation valve of the ventilator at the upper end,which was provided with an internal holding chamber for temporary storage of the condensate and a through hole at the bottom for connection to the outside.The mouth of the liquid collection bottle could be inserted into the through hole,and there are a number of side holes on the mouth.The sealing mechanism at the bottom of the temporary storage bottle was made up of a magnet and a magnetic sealing plate,of which,the magnet was on the bottom surface of the holding chamber and the magnetic sealing plate was adsorbed to the magnet to seal the through hole.The connection mechanism between the temporary storage bottle and the liquid collection bottle consisted of an annular sleeve,an internal thread and an external thread.Results The reservior cup facilitated timely elimination of the condensate in the ventilator pipeline without removing the access cover,maintaining mechanical ventilation during drainage for the ventilator-assisted therapy and minimizing the risk of aerosol diffusion in the operating area.Conclusion The reservoir cup with high convenience and safety eliminates the condensate quickly and shortens the retention time of bacteria in the ventilator pipeline effectively.[Chinese Medical Equipment Journal,2024,45(9):115-117]
