Problems solved by technology

[0002] At present, there are rich blood vessels in the joints of the limbs, and the blood vessels are thick and under high pressure. After being hit by bullets, pierced or pierced by hard objects, it is very easy to cause damage or rupture of the arterial vessel wall, thereby causing rapid blood loss of the wounded.
The blood loss and bleeding speed of this part is fast, the blood flow pressure is high, and its structural structure limits the use of conventional hemostasis methods such as pressure bandaging and tourniquet blocking, which is one of the main causes of hemorrhagic death
At present, there is a lack of solutions for blocking hemostasis and rapid coagulation for penetrating injuries of the above limbs or blind tract injuries in the prior art

Embodiment 1

[0040] Such as figure 1 As shown, the embedded active emergency hemostasis device is composed of three parts: an air storage module 10 , a control module 20 , and a retractable hemostatic air bag 30 .

[0041]The gas storage module 10 is connected to the control module 20 through a gas quick-connect plug and a quick-connect socket, which is convenient for disassembly. The control module 20 controls the air circuit solenoid valve to inflate and pressurize the hemostatic airbag 30, and realize pressure protection when the telescopic hemostatic airbag 30 is inflated and step-wise pressure reduction after hemostasis. The telescopic hemostatic airbag 30 is supported by two-stage nested pull-out struts, which expand and extend under the push of gas pressure to adapt to wounds of different shapes and sizes; Hemostatic material, after the airbag is inflated, the hemostatic material is fully contacted with the bleeding tissue of the wound, so as to achieve the purpose of hemostasis an...

Embodiment 2

[0048] The structure of this embodiment is the same as that of the above embodiment and will not be repeated, and this embodiment only introduces some changes or more specific structures.

[0049] The structural layout of the control module 20 is as follows: Pic 4-1 , shown in 4-2: the control module 20 includes a microprocessor, a pressure sensor 26, a solenoid valve 23, a quick-connect plug 21, a power supply module and a gas pipeline. The control box 22 integrates a microprocessor control circuit and a power supply circuit, and is fixed above the miniature solenoid valve 23 . The solenoid valve 23 adopts miniature low power consumption components, and one end of the valve body is connected with the gas storage module through the quick connector 21, and the other end is connected with the gas pipeline of the airbag pull-type strut. The pressure sensor 26 is placed in the independent air chamber of the pull-out strut to detect the pressure change in the air bag in real time...

Embodiment 3

[0053] The structure of this embodiment is the same as that of the above embodiment and will not be repeated, and this embodiment only introduces some changes or more specific structures.

[0054] The gas storage module of the embedded active first aid hemostasis device of the present invention can be specifically a gas storage cylinder. The gas storage cylinder includes a two-layer structure of an inner tank and an outer shell. Multi-layer coating structure, the multi-layer coating structure can be multi-layer aluminum foil or multi-layer infrared reflection layer. There is a vacuum layer between the inner tank and the outer shell, which has good heat insulation effect. The vacuum degree of the vacuum layer is preferably 0.1-0.01Pa. At this time, the thermal conductivity is very small, and the further reduction of the vacuum degree has little effect on the thermal conductivity; due to the good heat insulation effect of the gas storage cylinder, liquid carbon dioxide can be sto...

Abstract

The invention relates to an embedded hemostasis device, and belongs to the technical field of medical instruments. In the prior art, a wound at the joint of a limb is not easily stopped from bleeding.The embedded hemostasis device comprises an air storage device, a control device and an air bag; a disposable air storage bottle and the expanded type hemostasis air bag are used for the device to realize interdiction hemostasis and rapid coagulation of a penetrating injury or a typhlosolis injury to the joint of the limb through injury channel filling and pressurizing expanding under the controlof a self-adaptation pressure adjusting system.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a control device for a hemostasis device. Background technique [0002] At present, there are rich blood vessels in the joints of the limbs, and the blood vessels are thick and under high pressure. After being hit by bullets, hard objects pierced or pierced, it is very easy to cause damage or rupture of the arterial vessel wall, thereby causing rapid blood loss of the wounded. The blood loss and bleeding speed in this part is fast, the blood flow pressure is high, and its structural structure limits the use of conventional hemostatic methods such as pressure bandage and tourniquet blocking, which is one of the main causes of hemorrhagic death. At present, there is a lack of solutions for blocking hemostasis and rapid coagulation for penetrating injuries of the above limbs or blind tract injuries in the prior art. Contents of the invention [0003] In view of the proble...
