What are the types of medical electric suction?

Experts said that the type of medical electric suction can be divided into the following two ways: First, according to the type of vacuum pump division of medical use of electric suction according to its use of the type of vacuum pump can be divided into two types: 1, slide vacuum pump this vacuum pump contains oil, its mechanical noise. Vacuum pump in the oil storage room without oil or oil level is too low, or lift the oil ring does not rotate, it can not lubricate the vacuum pump, easy to burn the vacuum pump. 2, diaphragm vacuum pump that the vacuum pump is oil-free, its operation noise is small, usually do not need more maintenance. In the membrane type electric attractor there is electromagnetic structure of negative pressure attractor. This kind of attractor also utilizes the diaphragm to control the vacuum pump intake and exhaust to achieve the purpose of negative pressure attraction. Slide type electric attractor its vacuum pump if the seal is not tight, the lubricant is easy to leak, which will make the internal connection with the rubber tube aging, deterioration, resulting in air leakage, need to be frequently checked and replaced, in order to ensure the vacuum degree. In contrast, the diaphragm type attractor to be better. Second, according to the use of electric suction device according to the use of three kinds of division: that is, ordinary electric suction device, abortion-type electric suction device, gastric lavage type electric suction device. 1, ordinary electric suction device: specifically to do suction blood, water, pus, phlegm and other therapeutic use, can not be done for other therapeutic use. 2, abortion-type electric suction device: specializing in the abortion (i.e., suction) of the suction device. This type of suction device compared with other types of electric suction device, there are two differences: First, there are two 5000mL gas storage bottle, there are two 500mL liquid storage bottle: Second, there is a negative pressure automatic control part, used to maintain the set range of negative pressure values. 3, gastric lavage type electric suction device: specializing in gastric lavage suction device, the structure of this suction device is a vacuum pump positive pressure and negative pressure are used up. It has both positive pressure indicator table, also has a negative pressure indicator table, with a special knob switch to control the positive and negative pressure switch. In addition, it also has a regulating valve to control positive and negative pressure. At present, the new gastric lavage machine are equipped with positive pressure, negative pressure manual and automatic control function, not easy to block, very suitable for clinical emergency use.
