Manually-controlled positive and negative pressure pump comprehensive rescue device

Abstract

The invention relates to the field of critical first-aid medical science, and relates to a manually-controlled positive and negative pressure pump comprehensive rescue device, which comprises a positive and negative pressure pump, a blood storage bag and a chest closed drainage bag, wherein the positive and negative pressure pump comprises a pump body, a pump cover, an inlet conduit and an outlet conduit; two ends of the pump body are in a spindle shape; supports with a conical degree are arranged on the upper part and the lower part in the pump body; a pump cover is arranged on the top of the pump body; an inflow channel valve is arranged at the lower end of the pump cover and is connected with the inlet conduit; an auxiliary pump is arranged at the lower end of the pump body; an outflow channel valve is arranged in the auxiliary pump; and the outflow channel valve is connected with the outlet conduit. The manually-controlled positive and negative pressure pump comprehensive rescue device does not depend on an external power supply, generates power by extrusion of hands, can be connected with the blood storage bag and the chest closed drainage bag to recycle autologous blood, can be connected with a liquid / medicine storage bag and a spray machine head to spray and wash wounds and wound ways, and can be connected with a drainage object collection bag to perform absorption under negative pressure, phlegm absorption, gastrointestinal decompression, body cavity drainage and the like, so that a multi-functional comprehensive rescue system is formed.

Description

technical field [0001] The invention relates to a comprehensive rescue device capable of manually generating positive and negative pressure power, in particular a hand-controlled positive and negative pressure pump comprehensive rescue device suitable for group comprehensive rescue at various disaster sites. Background technique [0002] Among the wounded in various sudden disasters, about 15-20% of the seriously injured died at the scene of first-line rescue due to the short time limit. The main cause of death was technical problems, but it was more due to the routine use of rescue in the hospital Most of the equipment needs to be driven by power, but it is difficult to find power or other energy sources in the field or in the first aid of different occasions. Therefore, most of the equipment routinely used in the hospital will not be useful on the scene. A comprehensive ambulance device (Patent No. ZL902050877, 2008201885229) that can be used for acute autologous blood tra...

[0002] Among the wounded in various sudden disasters, about 15-20% of the seriously injured died at the scene of first-line rescue due to the short time limit. The main cause of death was technical problems, but it was more due to the routine use of rescue in the hospital Most of the equipment needs to be driven by power, but it is difficult to find power or other energy sources in the field or in the first aid of different occasions. Therefore, most of the equipment routinely used in the hospital is not useful on the scene

A comprehensive ambulance device (Patent No. ZL902050877, 2008201885229) that can be used for acute autologous blood transfusion, negative pressure suction, and closed thoracic drainage has been disclosed. Although the scope of ambulance has been extended from the hospital to the outside, it has not solved the following problems: Negative pressure requirements for high negative pressure suction; Negative pressure requirements for low negative pressure suction; Pressure discharge requirements provided by positive pressure and the need for multifunctional comprehensive rescue for a large number of wounded at the same time, etc.
