Description

{Stethscope for arteriovenous access}

The present invention relates to a stethoscope for dialysis access, and more particularly, to a stethoscope for a dialysis accessing stethoscope capable of detecting blood flow and a narrowed portion of a blood vessel in contact with an artery and a vein by hemodialysis .

A conventional analog stethoscope, invented by Laeneke in 1819, is a stethoscope including a thoracic sound detection part, an earpiece, and a tube connecting the thoracic sound detection part and earpiece part.

The stethoscope made of the mechanical type is widely used in a medical field so far, and recently it has been converted into an electronic stethoscope (analog amplification type).

When the stethoscope configured as described above performs long-term medical services, the degree of hearing loss and pain of the medical doctors reaches a serious level. As a result, there is a problem that a lot of troubles are encountered in treating the patient due to the pain to the ear of the medical doctors, leading to the cause of the out-of-service.

On the other hand, conventional analog stethoscopes and recent electronic stethoscopes have a relatively high rate of misdiagnosis due to the subjective judgment of the physician alone in listening to the doctor alone in detecting the chest sound, There was a problem that one-sided medical treatment was performed.

On the other hand, thrombosis is a substance that occurs as part of a hemostatic effect. Hemostasis is caused by contraction of the blood vessels and narrowing of the internal diameter of the blood vessels and blood coagulation factors to coagulate blood to prevent blood vessels from spilling out.

The hemostasis process can be divided into four stages: 1) contraction of the blood vessels, 2) thrombus formation due to platelet aggregation, 3) blood clotting, and 4) proliferation of fibrous tissue in the clotted blood. In other words, blood platelets and tissues are gathered in the collagen exposed from the wound area of blood vessels, and blood coagulation is started. The fibrotic tissue is proliferated in this area and the blood vessels are clogged. The thus formed thrombus is a cause of cerebrovascular diseases such as stroke It is.

Once the platelets are gathered around the collagen exposed by the wound, the coagulation of the platelets occurs, resulting in the freezing and oxidation of arachidonic acid, the reorganization of the platelets and the formation of blood clots There are many factors involved in the process of blood clotting as well as the production of blood clots.

However, in order to detect the conventional thrombus, there is a problem in that it is costly and time-consuming to proceed through the methods such as ultrasonography, CT, MRI, angiography, and radioisotope scanning.
