Problems solved by technology

However, in some cases, such as infants, young children, obesity, shock and edema, etc., because of their thinner arteries or weak pulsation; patients have arterial anatomical variations, and the arteries at the puncture site are not straight; in order to feel the arteries more clearly during puncture Pulsation, excessive finger pressing on the artery blocks the blood flow at the distal end of the artery; under special circumstances, the position of the doctor performing arterial puncture is limited, and the hands are difficult to operate, etc., which will increase the difficulty of palpation puncture and catheter placement, thereby increasing the number of repeated punctures and complications. disease

Abstract

The invention discloses a visible arteriopuncture catheter indwelling device, belonging to the field of medical equipment. The device consists of a four-dimensional color Doppler ultrasound machine, a semi-cylindrical Doppler detector, a handheld automatic puncture catheter indwelling device, a head-mounted augmented reality device and a main controller, wherein the semi-cylindrical Doppler detector is connected with the four-dimensional color Doppler ultrasound machine through a circuit; and the head-mounted augmented reality device, the handheld automatic puncture catheter indwelling device and the four-dimensional color Doppler ultrasound machine are connected with the main controller. By adopting the device, a doctor can easily find the best puncture point of artery, the puncture process of the doctor is simplified, the efficiency of the whole puncture catheter indwelling process is improved, and the pain of a patient is relieved.

Description

technical field [0001] The invention designs a visible arterial puncture catheterization device, which belongs to the field of medical instruments. Background technique [0002] Arterial puncture catheterization is a commonly used technique for anesthesia. It can not only realize real-time monitoring of blood pressure and arterial pressure waveform by connecting the pressure transduction system, but also facilitate the collection of blood samples, avoiding multiple arterial puncture blood collection. At present, the arterial pulse palpation method is generally used clinically for puncture and catheterization. However, in some cases, such as infants, young children, patients with obesity, shock and edema, etc., because of their thinner arteries or weak pulsation; patients have arterial anatomical variations, and the arteries at the puncture site are not straight; in order to feel the arteries more clearly during puncture Pulsation, excessive finger pressing on the artery blo...
