Description

Technical Field

[0001] The utility model relates to a water accumulation cup of a breathing machine, in particular to an automatic liquid discharge device for the water accumulation cup. Background Art

[0002] Ventilators are currently widely used in hospitals to rescue and treat patients. When using ventilators, humidification is required to prevent the patient's airway from drying out. While humidifying the patient, a large amount of condensed water is also generated in the ventilator pipeline. To deal with the condensed water, a water accumulation cup is currently installed in the ventilator pipeline to collect the condensed water.

[0003] In order to avoid excessive accumulation of fluid in the water cup, which may increase the resistance of the ventilator pipeline and cause suffocation of the patient in severe cases, the condensed water in the water cup must be dumped out in time, which increases the workload of nurses. In addition, the condensed water in the water cup includes saliva or secretions exhaled by the patient, and nurses are prone to infection when dumping the condensed water in the water cup, which seriously affects the health of nurses and is not conducive to daily care. Utility Model Content

[0004] In view of this, the utility model provides an automatic liquid discharge device for a water accumulation cup.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] An automatic drainage device for a water accumulation cup includes a water accumulation cup body, a drainage device is provided at the bottom of the water accumulation cup body, the drainage device has a hollow installation chamber, a drainage tube extending into the installation chamber is connected to the bottom of the water accumulation cup body, a one-way valve is provided in the drainage tube, an electric diaphragm pump is installed in the installation chamber, the electric diaphragm pump has a pump suction interface and a drainage interface, the pump suction interface is connected to the drainage tube, the drainage interface is connected to a drainage pipe, the distal end of the drainage pipe extends to the outside of the drainage device, and is connected to a water storage tank.

[0007] With the above structure, the condensed water in the water cup is automatically pumped out by an electric diaphragm pump and collected in a water storage tank through a drain pipe, without the need for manual dumping, thereby reducing the risk of infection. The one-way valve can prevent the condensed water from flowing back into the water cup, thereby ensuring that the internal environment of the water cup is not contaminated.

[0008] As a preferred embodiment, a boss extending downward is provided at the bottom of the water cup body, a water collecting tank communicating with the inside of the water cup body is provided on the upper side of the boss, and a drainage pipe is connected to the lower end of the boss. With the above structure, the condensed water generated by the ventilator flows into the water collecting tank first, and when there is less condensed water, the electric diaphragm pump can also pump out all the condensed water.

[0009] As a preferred embodiment, the drainage device is equipped with a time relay, which is connected to the electric diaphragm pump to control the electric diaphragm pump to drain water at a fixed time. With the above structure, the electric diaphragm pump can drain the condensed water in the water cup body at a fixed time without manual intervention, thus realizing automatic drainage.

[0010] As a preferred embodiment, a pair of disposable batteries are installed in the liquid discharge device, and a battery cover is provided on the outer wall of the liquid discharge device. The above structure is adopted to facilitate battery replacement.

[0011] As a preferred embodiment: a fixing frame is provided inside the drainage device, and two vertical mounting holes are provided in the middle of the fixing frame. The vertical mounting holes are used to install the electric diaphragm pump and the drain pipe. The two vertical mounting holes respectively extend two brackets horizontally outward to the inner wall of the installation chamber. The four brackets divide the installation chamber into four areas. The time relay, drainage pipe, and battery are respectively installed in three areas, so that the overall structure of the installation chamber is cylindrical. With the above structure, the electric diaphragm pump has good stability and avoids the problem of large pipeline vibration; the drainage device is small in size and the structure in the installation chamber is compact.

[0012] As a preferred embodiment, a switch button is provided on the outer wall of the liquid discharge device for starting the liquid discharge device. The above structure is convenient and quick.

[0013] Preferably, the port of the water cup body is connected to a water cup cover, and a Y-shaped connecting pipe is arranged at the center of the water cup cover, and the Y-shaped connecting pipe includes a vertical pipe and two inclined pipes, the vertical pipe is connected to the inside of the water cup body, and the inclined pipe is connected to the ventilator pipeline. With the above structure, condensed water in the ventilator pipeline flows into the water cup body along the vertical pipe through the inclined pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Use the time relay to control the start of the electric diaphragm pump, which can automatically and regularly discharge the condensed water in the water cup. The condensed water is discharged out of the device through the drain pipe and collected in the water storage tank for centralized treatment. There is no need for manual dumping, and the condensed water is not exposed, avoiding pollution and reducing the use of manpower.

[0016] 2. A one-way valve is installed between the water cup body and the electric diaphragm pump. The condensed water can only flow out of the water cup and cannot flow back, so that the water cup is isolated from the external environment and the environment inside the water cup is not polluted.
