Mechanical transmission safety protection device for electric suction apparatus

Abstract

The invention discloses a mechanical transmission safety protection device for an electric suction apparatus. The mechanical transmission safety protection device comprises an electric suction apparatus main body, a first storage bottle, a second storage bottle and a floater power cutoff device, wherein the electric suction apparatus main body mainly comprises a vacuum pump and an electric suction apparatus main switch. The mechanical transmission safety protection device is characterized in that: the first storage bottle and the second storage bottle are arranged on a platform at the front end of the electric suction apparatus main body; a first silicone tube is connected to the first storage bottle; the first storage bottle is connected with the second storage bottle through a second silicone tube; the second storage bottle is connected with a vacuum pump of the electric suction apparatus main body through a third silicone tube; and the floater power cutoff device is arranged on a bottle cap of the second storage bottle, and is used for controlling the electric suction apparatus main switch to control power supply for the vacuum pump through a lead. The mechanical transmission safety protection device has the beneficial effects of small external influences, avoidance of influences of factors such as blockage, loss and the like, and high sensitivity, and is particularly suitable for sucking a large quantity of liquids during rescuing of patients and surgical treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method that can automatically monitor the liquid level of an electric suction device storage bottle, intelligently judge that when the capacity of the liquid in the storage bottle reaches a limited capacity, the electric suction device will automatically stop working to prevent the liquid from entering the machine And the mechanical transmission safety protection device of the electric suction device with protective function. Background technique [0002] Although the commonly used electric suction device is equipped with an overflow protection device at the outlet of the second liquid storage bottle to prevent the liquid from entering the middle pipe and entering the interior of the machine, due to various reasons such as blockage and loss of the overflow protection device, The effect is inaccurate, and when drawing large amounts of liquid, it is easy to draw liquid in...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the inaccurate effect of the above-mentioned overflow protection device and avoid the problem that the liquid enters the machine and burns out the vacuum pump, the present invention provides a method of monitoring the liquid level of the storage bottle of the electric suction device by using a liquid height probe. When the capacity of the liquid in the suction bottle reaches the limited capacity, the electric suction device stops working to prevent the liquid from entering the machine and play a protective role in the mechanical transmission safety protection device of the electric suction device
