Pen-type venous occlusion device

Abstract

The invention discloses a pen-type venous occlusion device. The device comprises a scanning probe, a casing, a controller, a liquid crystal screen, a battery pack and a control switch, wherein the scanning probe is arranged at the front end of the casing, a pressure sensor is arranged on the surface of the scanning probe, and an ultrasonic transducer is arranged in the scanning probe; the liquid crystal screen is arranged on the outer surface of the upper part of the casing, and the control switch is arranged at the top end of the casing; the pressure sensor, the ultrasonic transducer, the liquid crystal screen and the control switch are respectively connected with controller which is arranged inside the casing; the battery pack is arranged in the casing and connected with the controller. The pen-type venous occlusion device is novel in structure and convenient to use, can be used for observing the situation of blood vessels and preventing angiectopia of neck, oxter or other parts during PICC or port-cath cathetering, can be used when PICC or port-cath ectopia is treated by a finger-press method, can be used for assisting a doctor to observe the situation of venous occlusion and pressing occluded veins by proper pressure according to requirement, so that ectopic catheter or port-cath is restored to a normal position.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a pen-type venous occlusion instrument for restoring PICC venous reentrant ectopia and infusion port ectopia. Background technique [0002] Peripherally inserted central catheter (PICC): a central catheter is inserted through a peripheral vein (such as basilic vein, median cubital vein, cephalic vein, etc.), and the tip of the catheter is located at the lower 1 / 3 of the superior vena cava and the right The junction of the atria, that is, the right atrial appendage. It is suitable for medium and long-term intravenous infusion, tumor chemotherapy, parenteral nutrition, and infusion for elderly patients. Since the 1990s, the United States has introduced B-ultrasound guidance combined with Seidinger technology into PICC catheterization. At present, this technology is mostly used in clinical practice. However, due to anatomical variation, poor coordination of the patient...

Problems solved by technology

At present, the commonly used clinical implantation routes are the chest wall infusion port through the subclavian vein and the arm infusion port implanted through peripheral blood vessels such as the basilic vein, brachial vein, and median vein of the arm, and cervical and axillary heterotopias also exist.
