Detailed Description
The following describes the water replenishing device for the humidification tank of the breathing machine in detail with reference to the attached drawings.
The utility model provides a moisturizing device for breathing machine humidifying jar, it includes: an infusion set 20, a permanent magnet 12, a cannula 13, a float member.
The infusion set 20 includes an exhaust tube. The infusion set 20 of the present application is the same as the existing ordinary infusion set except for the lower end connector. The lower end connector 21 of the tubing of the infusion set 20 comprises a central cannula 23 and an outer peripheral ferrule 22; the upper end of the peripheral ferrule 22 is fixed with the upper end of the central cannula 23; the central cannula 23 is used for being inserted into the water adding port 11 of the humidification tank 10, and the outer diameter of the central cannula 23 is equal to the inner diameter of the water adding port 11; the peripheral collar 22 is adapted to fit snugly over the outer periphery of the watering port 11. An O-ring seal 24 is provided along the inner periphery of the outer peripheral collar 22.
The permanent magnet 12 is formed into a ring shape, is sleeved on the water adding port 11 of the humidification tank 10 and is positioned right below the lower end connector 21 of the infusion apparatus 20.
The pipe body 13 is arranged in the humidifying tank 10 and is positioned right below the water adding port 11 corresponding to the water adding port 11 of the humidifying tank 10; an iron ring 13a is embedded in the upper end of the pipe body 13, and the permanent magnet 12 adsorbs the iron ring 13a, so that the pipe body 13 is adsorbed and installed at the lower side of the water adding port 11; the upper end of the tube body 1 is formed to be open, a through hole is formed on the circumferential wall of the tube body 13, the lower end of the tube body 13 is closed by an end cap 16, and a through hole is formed at the center of the end cap 16.
The float member is mounted within the tube 13; the floater component comprises a connecting rod 17, the upper end of the connecting rod 17 is fixed with a rubber hollow ball 14, and the lower end of the connecting rod 17 is fixed with a hollow floater body 18; the rubber hollow sphere 14 is accommodated in the tube body 13, and the lower end of the connecting rod 17 passes through the through hole of the end cover 16 and extends to the lower part of the end cover 16; the rubber hollow sphere 14 is used for plugging the water adding port 11 from the lower part. The middle part of the tube body 13 is provided with an annular baffle plate 15; the upper end of the connecting rod 17 passes through the annular baffle 15, and the through hole of the end cover 16 and the annular baffle 15 form a guide passage of the connecting rod 17.
When in use, firstly, the bottom cover of the humidifying tank is opened, and the pipe body provided with the floater component is arranged right below the water adding port, so that the rubber hollow ball of the floater component is opposite to the water adding port; because the permanent magnet arranged on the water adding port attracts the iron ring at the upper end of the tube body, the floater component and the tube body are fixed at the lower side of the upper end of the humidification pot body; one advantage of this is that the tube body is easy to be taken off, and the lower side of the upper end of the humidification pot can be kept flat, which is convenient for disinfection and cleaning; the tube and float member may be disposable; the humidification tank can be used repeatedly after being sterilized; the central insertion tube of the lower end connector of the infusion apparatus with the exhaust pipe is inserted into the water adding port, and the periphery of the central insertion tube is tightly sleeved on the periphery of the water adding port in a surrounding manner; therefore, the lower end joint is fixed inside and outside the water adding port respectively, so that the lower end joint and the water adding port are firmly combined. The water in the water bottle connected with the upper end of the infusion apparatus flows into the water adding port through the pipeline of the infusion apparatus and the lower end joint, then flows into the tube body, and flows into the humidifying tank body through the through holes on the peripheral wall of the tube body; when the water level is higher than the preset position, the floater component is floated by the rising water level in the humidifying tank body through the floater body, so that the rubber hollow ball blocks the lower end of the water adding port, and therefore, water injection is interrupted; when the water level in the humidifying tank body is lowered, the floater component is lowered under the action of gravity, the rubber hollow ball leaves the lower end of the water adding port, and water injection can be continued. Thus, the water filling will be continued as long as there is water in the water bottle, and will be stopped as long as the water level in the humidification tank body is higher than the predetermined level, without the need for nurse intervention.
