What are the types of medical electric aspirators?

Experts said that the types of medical electric aspirators can be divided into the following two ways: First, according to the type of vacuum pump, the electric aspirators used in medical treatment can be divided into two types according to the type of vacuum pump they use: 1, vane vacuum pump, which contains oil and has high mechanical noise. When there is no oil in the oil storage chamber of the vacuum pump or the oil level is too low, or the oil lifting ring does not rotate, the vacuum pump cannot be lubricated and is easy to burn out. 2. Diaphragm vacuum pump has no oil, low running noise and no need for more maintenance at ordinary times. There is also a negative pressure suction device with electromagnetic structure in the membrane electric suction device. This kind of suction device also uses diaphragm to control the intake and exhaust of vacuum pump to achieve the purpose of negative pressure suction. If the vacuum pump of the sliding electric suction device is not tightly sealed, the lubricating oil is easy to leak, which will make the rubber tube for internal connection deteriorate and cause air leakage, so it needs to be checked and replaced frequently to ensure the vacuum degree. Comparatively speaking, diaphragm suction device is better. Two, electric suction device according to the use of ordinary electric suction device, induced abortion electric suction device, gastric lavage electric suction device three kinds. 1. Ordinary electric aspirator: it is specially used for the treatment of blood sucking, water, pus and phlegm, and cannot be used for other treatments. 2. Induced abortion type electric aspirator: an aspirator specially used for induced abortion (i.e. uterine aspiration). Compared with other types of electric aspirators, this kind of aspirator has two differences: first, it has two 5000mL gas cylinders and two 500mL liquid storage bottles; The other is that it has a negative pressure automatic control part to keep the set negative pressure range. 3. Gastric lavage electric aspirator: an aspirator specially used for gastric lavage. The structure of this suction device is to use the positive pressure and negative pressure of vacuum pump. It has both positive pressure indication and negative pressure indication, and uses a special knob switch to control the switching between positive pressure and negative pressure. In addition, it has a regulating valve to control positive pressure and negative pressure. At present, new gastric lavage machines are equipped with positive and negative pressure manual and automatic control functions, which are not easy to be blocked and are very suitable for clinical emergency use.
