Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a chest cavity sealing, hemostasis and fluid extraction device used for battlefield emergency treatment. Background Art

[0002] When a person breathes, the lungs rely on two layers of pleura to move with the movement of the thorax. The two layers of pleura form a closed pleural cavity, which contains only a small amount of serous fluid but no gas. On the battlefield, when a soldier is shot or shrapnel penetrates and causes the pleural membrane to rupture, air will enter the thoracic cavity, forming a pneumothorax, which reduces the ability of the lungs to move with the thorax. At the same time, the blood flowing out of the chest wall blood vessels accumulates in the thoracic cavity, which will compress the lungs and heart, further leading to difficulty breathing, which can quickly lead to respiratory distress and shock, further increasing the mortality rate of battlefield casualties. Although pneumothorax has a high mortality rate, its battlefield first aid technology is not complicated, and combat lifesavers (CLS) or medical soldiers can handle it after training.

[0003] In the first aid stage at the battlefield, the current level of attention paid to the assessment and treatment of pneumothorax is not enough, and the treatment concepts, techniques and equipment are relatively backward. It is very necessary to develop first aid treatment equipment for pneumothorax that is suitable for the battlefield environment and takes into account the physical characteristics of our officers and soldiers. Summary of the invention

[0004] In view of the above problems, the present invention provides a chest sealing hemostasis and fluid extraction device for battlefield emergency treatment, which has a simple structure and is easy to operate. It can quickly and efficiently achieve chest ballistic hemostasis, lung sealing and extraction of pleural effusion for bullet-struck casualties.

[0005] The present invention adopts the following technical solutions:

[0006] A chest sealing, hemostasis and fluid extraction device for battlefield emergency treatment comprises a sheath component, an airbag component, a pressure plate component and a hose component. The sheath component, the airbag component and the pressure plate component are sequentially mounted on the hose component from bottom to top.

[0007] The sheath component comprises a sheath at an upper end and an end head at a lower end, and a support frame is arranged between the sheath and the end head; the support frame can be expanded or contracted.

[0008] The airbag component includes an airbag and an air inlet pipe above the airbag. When in use, the airbag is inflated through the air inlet pipe until the airbag expands and presses the chest wall to stop bleeding.

[0009] The pressing plate component comprises a pressing plate and a clamping plate on the upper surface of the pressing plate, wherein the clamping plate is used to fix the hose component and the air inlet pipe. When in use, the pressing plate is pushed downward along the hose to press the chest wall.

[0010] The hose component includes a hose, and a tooth-shaped tube is provided on the outer surface of the upper part of the hose. After the pressing plate is pushed to a suitable position, the inverted teeth on the tooth-shaped tube can fix the pressing plate, and cooperate with the inflated airbag to complete the sealing and compression of the chest wall. The excess gas and liquid in the chest cavity are connected to an external air pump through the hose to be pumped out. A compression ring is provided on the lower part of the hose between the sheath component and the airbag component.

[0011] Preferably, a steel mesh is provided on the bottom surface of the end head to prevent the broken tissue in the chest cavity from entering the hose and avoid blockage.

[0012] Preferably, the support frame is composed of a plurality of connecting rods, each connecting rod includes an upper and a lower section, which are connected by a movable hinge in the middle. When downward pressure is applied, the connecting rod bends outward, driving the sheath to open, which can prevent the airbag from squeezing the lungs downward after expansion.

[0013] Preferably, the pressing plate is a transparent plastic plate, which facilitates observation of whether the pressing plate and the airbag are pushed into place.

[0014] The compression ring is made of rubber, which provides the device with adjustment space and also plays a buffering role to prevent the user from damaging the sheath component by applying excessive force.

[0015] Preferably, the pallet is a detachable structure, so that it can be quickly removed for the next step of treatment after the injured person is out of danger.

[0016] Preferably, the pressing plate and the clamping plate have a variety of connection methods, such as connection by screws or connection by buckles.

[0017] The beneficial effects of the present invention are:
