Oncometer

A tumor meter is a device that is used to measure the volume of blood circulating in one of the limbs of a person or animal.

The operating principle of the oncometer is based on plethysmography, a method that allows recording changes in the volume of an organ or tissue. In an oncometer, this is achieved by using a cuff that is placed around the limb and periodically inflated, creating pressure that prevents normal blood flow. In this case, fluctuations in pressure in the cuff are recorded, corresponding to changes in blood volume in the limb during the cardiac cycle.

Oncometry, that is, measuring blood volume using an oncometer, can be used to diagnose and monitor the condition of the cardiovascular and lymphatic systems. This method allows you to evaluate the elasticity of blood vessels, blood flow speed, and also identify pathologies associated with blood circulation disorders.



A tumor meter is a device that is used to measure the volume of blood in one limb. It works based on the principle of plethysmography, which consists in changing the volume of blood in a limb when the air pressure in it changes.

An oncometer consists of a cuff, which is placed on the arm or leg, and a pressure sensor, which is located inside the cuff. The cuff is inflated to a certain pressure and then slowly deflated. As the cuff deflates, the volume of blood in the limb decreases, which leads to a change in pressure in it. The pressure sensor records these changes and transmits the information to the computer, where it is processed.

Oncometer measurement results can be used to diagnose various diseases, such as heart failure, vascular diseases, and also to evaluate the effectiveness of treatment. It can be used both in medical institutions and at home.

Overall, the oncometer is an important tool for diagnosing and treating various circulatory-related diseases. It allows you to obtain accurate and reliable data on the patient’s health status and helps doctors make the right decisions in treatment.



An oncometer is a device that is used to measure the volume of blood circulating in one of a person's limbs. It is used in medicine to diagnose various diseases associated with circulatory disorders.

The operating principle of the oncometer is based on measuring changes in the electrical resistance of tissues during blood flow. As blood begins to flow into the limb, its volume increases, resulting in increased tissue resistance. This change in resistance is recorded by the device and displayed on the display in the form of a graph.

The Oncometer can be used to measure blood flow in various areas of the body such as arm, leg, head, etc. This allows the doctor to obtain information about the state of blood circulation in a particular area, which makes it possible to diagnose various diseases associated with impaired blood flow.

In addition, the oncometer is used to monitor the effectiveness of treatment for diseases associated with blood circulation. For example, when treating arterial or venous disease, a doctor may use a tumor meter to measure changes in blood flow after treatment.

In general, an oncometer is an important tool in medicine, which provides information about the state of blood flow in the body and helps in the diagnosis and treatment of various diseases.



An oncometer or plethysmograph is a device designed to determine the difference in blood volume between the muscles of one limb. During the examination, the forearm is compressed with a tourniquet, then air is removed from the applied tourniquet through one tube, and from the opposite shoulder through another tube. When the vessels are compressed, the muscles contract and the cross-sectional area of ​​the vessels decreases. Since after normalization of pressure the volume of the cavity of the arteries increases, air begins to be displaced from the first tube. Over time, the volume of air displaced from the artery per unit time will be the same. It is calculated and the volume of blood in the artery is pressed with a punt to the usual position.
