With the development of technology and the need for management, medical aspirator is also constantly evolving. In general, there are several trends:
With the improvement of people's living standards, the health requirements are also increasing, the number of hospital beds is also increasing, and the demand for the use of suction unit is also significantly increased. If the previous independent electric suction devices are still used, it is obviously unwise in terms of cost and benefit. Therefore, large hospitals generally use centralized central pressure to solve this problem. The negative pressure interface on the equipment belt of the ward and the operating room is convenient, safe, easy to deploy in large quantities, convenient to manage, and low in cost. It has become a development direction of the medical suction unit.
In the electric aspirator, taking full advantage of the "electricity" advantage, a batch of medical suction units controlled by intelligent single-chip microcomputers emerged. Such as electric gastric lavage machine, is an intelligent control device that integrates positive pressure and negative pressure. Through the control of the program in the single-chip microcomputer, it completes a series of functions of flushing and absorbing, which facilitates the work of medical staff, improves efficiency and reduces errors. There are also intelligent negative suction physiotherapy devices based on the emerging theory of traumatic negative therapy in recent years, which are intelligent suction devices.
Compared with medical rescue in conventional fixed locations, a portable and convenient suction device is needed in emergency situations such as battlefields and disaster relief or in outdoor situations where it is temporarily used. Therefore, in recent years, there have gradually been suctioners, manual suction devices and foot suction devices that generate negative pressure by manual or foot pedaling. Because it is small in size, light in weight, easy to carry, simple to operate, and can be used without power source, it is especially suitable for use in remote areas without power supply, rural health centers, home care, field first aid and power failure.
