Description
Technical Field
The invention belongs to clinical emergency medical and surgical application equipment, in particular to a rechargeable craniocerebral injury operation suction device which is used in field emergency and can be used for routine operations.
Background
In the process of clinical surgery, negative pressure suction is one of necessary facilities. The central negative pressure suction device is used in most operating rooms of modern hospitals, and the electric suction device is widely applied, so that the negative pressure suction requirement of most medical operations can be met. The above equipment requires a large vacuum pump, a long fixed pipeline, a ground mobile suction bottle, an alternating current power supply and an external power supply lead. Through patent retrieval, the suction bottle of the negative pressure suction device is not placed on an operating table for use. Various portable rechargeable suction apparatuses are also used, but are also used under the operating table in a sterile condition.
When emergency rescue is carried out under field conditions or large earthquake disasters, enough alternating current power supply is often lacked, so that the field emergency operation or other operations such as emergency tracheotomy are easily limited by insufficient hardware facilities. The space of the field operation shelter operating room is narrow, and the active idea is to reduce ground mobile equipment and external power supply wires as much as possible. In the event of a major earthquake in Wenchuan in 2008, the operating room of the first subsidiary hospital of the university of medical science in Chengdu Huaxi, which was 97 km away from the earthquake, was mostly immediately powered off and the equipment failed, and the operation was forced to be aborted, which would be fatal to the craniocerebral operation in which the hemostasis operation was being performed. The operating rooms of the county-level hospitals around the earthquake center are almost all heavily created and can only be deployed in open areas as tent operating rooms. In order to reduce the dependence of the suction device on an alternating current power supply in an operation, the invention provides a rechargeable suction device for field emergency.
In the field condition or earthquake disaster emergency rescue, the serious shortage of blood products is one of the important bottlenecks for restricting the development of field rescue operations, and the blood liquid is recovered by using the negative pressure suction bottle and the liquid storage bottle under the sterile condition and is correspondingly treated, so that the basic condition is provided for autologous blood transfusion, and the method is a beneficial choice.
The existing operation is more and more precise, the total amount of the general bleeding and the total amount of the flushing fluid of the craniocerebral operation are not very large, and the negative pressure suction of the rechargeable operation suction device and the volume of the suction bottle for the field emergency are enough for the requirement of the craniocerebral injury emergency operation.
The development of high-energy polymer lithium batteries is fast, wherein a 18650 type lithium battery is in a cylindrical shape, the cross section diameter is 18mm, the height is 65mm, and the volume is 16532.1mm3The storage capacity can reach more than 3000mAh, the weight is only 45g, and the vacuum pump with the power of 10W can continuously work for more than ten hours. At present, rechargeable household barreled water pumping devices are widely used, for example, a tiger-type leap brand barreled water pumping device has the power of 4W/4.2V and the battery capacity of 1200mAh, can pump 8-10 barrels of barreled water after being charged once, can continuously work, can suck water with the volume of 350ml every ten seconds, and is enough for attracting the needs of craniocerebral injury surgery. The performance of the water pumping device can be improved by times by using a large-capacity lithium battery and a high-power vacuum pump, and the requirements of more major operations on the suction device are met.
