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

[0050] When using the embedded active emergency hemostasis device of the present invention to implement rescue, the following steps are specifically adopted:

[0051] Step S10 inserting the hemostatic device into the wound, as follows:

[0052] The structure diagram of the device insertion state is as follows: figure 2 shown. When performing penetrating wound hemostasis on site, first tear open the sterile packaging bag and take out the device, rotate the gas storage module 10 180° along the axial direction of the gas joint, manually unscrew the flow regulating valve of the gas storage module, and hold the gas storage module with one hand. can, quickly insert the telescopic hemostatic airbag 30 along the wound tract, and then inflate and pressurize. For penetrating wounds, it should be confirmed that the retractable hemostatic airbag is fully inserted; for blind wounds, it should be confirmed that the airbag pull-out strut has been inserted to the innermost end of the wound...

Embodiment 2

[0056] The same steps in this embodiment as in the above embodiment will not be repeated, and this embodiment only introduces some changes or more specific steps.

[0057] When the embedded active emergency hemostatic device of the present invention is inserted into the wound, the control module controls the hemostatic device to pressurize and expand to stop bleeding. The control principle is as follows:

[0058] Such as Figure 6 As shown, the control principle of the embedded active emergency hemostasis device is shown. Under the control of the microprocessor, the embedded active first aid hemostasis device uses a micro pressure sensor to detect the pressure of the air bag in real time, and controls the gas storage bottle to pressurize and inflate the air bag and deflate the air bag by controlling the solenoid valve of the air circuit, so as to realize the internal healing of the wounded tract. The airbag expands to produce compressive hemostasis, and after a stable thrombu...

Embodiment 3

[0073] Such as Figure 7 As shown, this embodiment provides a specific software control flow chart.

[0074] When the embedded active emergency hemostasis device of the present invention is inserted into the wound, the control module performs system control; first, the system starts self-inspection, and the system self-inspection includes detecting whether the pressure sensor is normal, whether the air source is turned on, whether the relay switch is normal and whether the battery voltage is normal. Normal, and at the same time light up each status indicator in sequence. If the functions of the above components are abnormal, when the abnormal alarm indicator lights up, it indicates that the control module has failed the power-on self-test, and the buzzer will generate a sound alarm; if an alarm occurs, it is necessary to manually solve the cause of the alarm, and then restart the machine. Repeat the self-test until it passes.

[0075] After the system completes self-inspecti...

Abstract

The invention relates to a haemostasis device control device and a control method thereof, and belongs to the medical apparatus technical field; the bleeding in a limb junction wound is hard to stop in the prior art; the control method comprises the following steps: S10, inserting the haemostasis device into the wound; S20, using the haemostasis device to pressurize for haemostasis and fixation. Under the control of an adaptive pressure adjusting system, the haemostasis device can realize limb junction penetrating injury or typhlosole wound blockout haemostasis and rapid blood clotting in a wound channel filling and pressurization expansion mode.
