Automatic compression hemostat for arteria femoralis

Abstract

The invention relates to the field of medical apparatuses, and discloses an automatic compression hemostat for the arteria femoralis. The automatic compression hemostat comprises a shell, a compression pad, an adjusting rod, blood pressure sensors, a pressure sensor, a controller and a driving device. The blood pressure sensors, the pressure sensor and the driving device are electrically connectedto the controller. The blood pressure sensors are arranged at one side of the shell. The adjusting rod is slidably arranged at the shell, and the compression pad is arranged at one end of the adjusting rod so that the compression pad can follow the adjusting rod to move away from or close to the side, provided with the blood pressure sensors, of the shell. The driving device cooperates with the adjusting rod to be arranged at the shell. The pressure sensor cooperates with the adjusting rod. During use, the automatic compression hemostat for the arteria femoralis is fixed to puncture points ofthe arteria femoralis, so that the compression pad is arranged outside the puncture points. The blood pressure sensors can detect the current blood pressure value of a patient, and the controller controls the driving device according to blood pressure, so that the compression strength is suitable.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a femoral artery automatic compression hemostat. Background technique [0002] In clinical practice, femoral artery puncture is often used in tumor interventional therapy. After the operation, the femoral artery puncture point should be pressed by hand to stop bleeding for 12-20 minutes. At the same time, the limb on the operated side should be straightened and immobilized for 6-8 hours. The puncture site should be compressed with 1KG sandbag for 6 hours. However, the patient is tired after the operation and has no strength to press the femoral artery puncture point for a long time. If the pressing position is not accurate or the intensity is not enough, a large amount of blood will be lost, threatening the life of the patient. [0003] To solve this problem, oppressors were designed. However, the compression force of these compressors is determined based on the experience of med...

AI Technical Summary

Problems solved by technology

This results in too much or too little compression

If the pressurization pressure is too high, it will affect the blood circulation of the limbs, cause swelling, numbness and pain of the patient's limbs, and damage the skin. If the purpose of hemostasis is not achieved, it may cause bleeding at the puncture site, hematoma, pseudoaneurysm, etc.

At the same time, these oppressors adjust the compression force manually, which is inconvenient to use
