Description

TECHNICAL FIELD

[0001] The utility model relates to electric air pump technical field, more specifically, relate to a kind of electric air pump for inflatable transfer pad. BACKGROUND

[0002] Bed sore (also known as pressure sore, pressure ulcer) is one of the common problems of hospitalized patients and people living in nursing institutions, due to the local tissue of the patient being under pressure for a long time, resulting in continuous ischemia, hypoxia and malnutrition, leading to tissue ulcer and necrosis. At present, inflatable transfer pad has become an effective solution to prevent bedsores due to its excellent load-bearing, mobility and good air permeability, which can effectively reduce the shear force on the skin tissue of the patient during transfer. When using the air pump to inflate the pad, the pad expands due to the increase of internal air pressure, forming an air layer between the patient and the bed surface, greatly reducing the frictional resistance during patient transfer, facilitating the operator to transfer.

[0003] The air pump configured in the inflatable transfer pad on the market is mostly entry-level, which has the problems of low air pump output pressure, high maintenance cost, poor durability and limited filtering effect. The filter element of such air pump is limited in material and design due to its own cost, and its filtering effect is relatively weak, which cannot effectively filter out all impurities and particulate matter, resulting in low quality of air entering the air pump. Under long-term use, the filter element is often blocked due to accumulation of too much impurities, causing poor air intake of the air pump, thereby reducing the output pressure of the air pump and causing unstable air flow, which directly affects the performance of the air pump. Therefore, in order to ensure the normal operation of the air pump and the cleanliness of the air, the user needs to frequently replace the filter element, which not only increases the maintenance cost, but also brings inconvenience to the user.
