Portable one-line comprehensive rescue apparatus

Abstract

The invention relates to a portable front-line integrated rescue device, which belongs to the medical rescue field. The invention discloses a hollow cylindrical secondary pump, which is connected with a main pump, an inlet connecting tube is arranged at the upper part of the secondary pump, a secondary one-way flapper is sleeved at the lower end of the inlet connecting tube, an outlet connecting tube is arranged at the lower part of the secondary pump, the main pump and the secondary pump are connected through an outlet connecting tube at the lower part of the main pump being connected with the inlet connecting tube of the secondary pump, the series pump body composed of the main pump and the secondary pump and a bag body with the flapper function are connected through the inlet connecting tube of the main pump being connected with a bag body or the outlet connecting tube of the secondary pump being connected with the bag body, and more than one connecting tube with one end being inserted into the bag body is arranged on the bag body. The portable front-line integrated rescue device has the advantages that the volume is small, the weight is light, the structure is simple, the operation is convenient, stable positive pressure and negative pressure with enough strength can be produced, the function of reducing tissue and blood injury which conforms the physiological requirements can be provided, the device can be freely assembled to realize the interchanging and the interaction of the multi-rescue functions, and the device is particularly applied to the integrated rescue in all disaster sites or wars.

Description

technical field [0001] The invention relates to a comprehensive rescue device, in particular to a portable comprehensive rescue device which can be widely used in various disaster sites. Background technique [0002] Although there are many types of existing equipment such as autologous blood transfusion, closed drainage, and negative pressure suction, their functions are single. Usually, one equipment can only provide one function, and cannot undertake multiple injuries and multi-functional comprehensive rescue in emergencies. Such equipment needs to be driven by power supply, such as autologous blood transfusion system, which is represented by Bentley and Polystan cardiac blood storage system (Cardiotomy reservoirs, BCR) in foreign countries. Although this device is stable in function, it is bulky and can only be fixed in the hospital. Most closed thoracic drainage systems that are commonly used outside the hospital are limited to bedside use and cannot be used in an emerg...

Problems solved by technology

[0002] Although there are many types of existing equipment such as autologous blood transfusion, closed drainage, and negative pressure suction, their functions are single. Usually, one equipment can only provide one function, and cannot undertake multiple injuries and multi-functional comprehensive rescue in emergencies. Such equipment needs to be driven by power supply, such as autologous blood transfusion system, which is represented by Bentley and Polystan cardiac blood storage system (Cardiotomy reservoirs, BCR) in foreign countries. Although this device is stable in function, it is bulky and can only be fixed in the hospital. Most closed chest drainage systems that are commonly used outside the hospital are limited to bedside use and cannot be used in emergency on-site

If these multiple types of equipment with a single function are combined and transferred to the disaster site for use, not only are they restricted by volume, weight, geographical environment, transportation and other conditions, but it is also difficult to cope with the need for simultaneous rescue of a large number of multiple types of wounded

Chinese patent ZL902050877 discloses a device that can be used for autologous blood recovery, pressurized blood transfusion, negative pressure suction, and closed drainage. Ambulance, however, this invention does not solve the following problem: how to construct a stable positive and negative pressure power system without power supply at the front line? How to make it able to generate both positive and negative pressure with sufficient strength and power suitable for low negative pressure suction, for example, low negative pressure suction is required for autologous blood recovery, blood transfusion, and gastrointestinal decompression, so as not to cause damage to tissues and blood damage?
