AI Technical Summary
Existing femoral artery puncture compression hemostasis devices require medical staff to spend a lot of time and effort adjusting the position and pressure. When used for a long time, the compression band needs to be loosened frequently, resulting in a heavy workload and potentially delaying the hemostasis time. Prolonged compression may lead to limb ischemia and necrosis.
A femoral artery compression hemostasis nursing device was designed after surgery in oncology. It is fixed to the femoral artery using a main compression band and a pressure component. The inflation state of the airbag is adjusted by the control component to achieve rapid initial fixation and long-term hemostasis. Combined with an arc plate and polyphenol modified hemostatic sponge, it provides multiple pressure modes to ensure hemostasis effect.
This method achieves simple and quick compression hemostasis, reduces the workload of medical staff, avoids limb ischemia or necrosis caused by prolonged compression, and ensures effective hemostasis at the puncture site.

TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to a postoperative femoral artery compression hemostasis nursing device for oncology. BACKGROUND
[0002] Puncture biopsy of tumors is an invasive examination for determining the nature of lumps, and the pathological results obtained are the gold standard for diagnosing tumors, which mainly includes biopsy of femoral artery puncture, lymph node puncture, etc. The femoral artery is the main trunk of the lower limb artery, and the pulsation can be felt at the superficial position of the midpoint of the groin. After femoral artery puncture, the femoral artery needs to be compressed for hemostasis.
[0003] The compression hemostat is a medical device for controlling bleeding, which mainly compresses the blood vessels by applying pressure to stop blood flow and achieve hemostasis. However, after puncture biopsy of the femoral artery, due to the high pressure in the artery, compression hemostasis of the puncture site needs to be pressed for about 15 minutes, then wrapped with gauze pad and bandage for about 8 hours, and the compression time needs to be paid attention to during this process. It needs to be loosened for about half an hour, relaxed for 1-2 minutes, and then pressurized again. If the compression is long, it may cause long-term ischemia of the patient's limbs, leading to necrosis of the limbs.
[0004] The existing compression hemostasis device needs to spend more time and effort to adjust the position and pressure by medical staff during the early compression hemostasis, which may delay the hemostasis opportunity. The compression hemostasis belt with the existing structure needs to be loosened by medical staff at regular intervals during the long-term use in the later period, which is a heavy workload for medical staff.

[0018] 1. The tumor internal medicine postoperative femoral artery compression hemostasis nursing device provided by the application fixes the whole compression hemostasis nursing device at the femoral artery by using the main compression band, controls the inflation state of the air bag to adjust the tightness of the fixed main compression band, and uses the pressurizing assembly to pressurize and hemostasis the puncture position of the femoral artery. The whole compression hemostasis nursing device is convenient to operate, and has good compression hemostasis effect on the puncture position.
