Hemoretractiometer

A hemoretraction meter (from the Latin “haemo” - blood, “retractio” - retraction, “metreo” - to measure) is a medical device that is used to measure the volume of blood in blood vessels and determine its rheological properties. It consists of two main parts: a measuring unit and a suction device.

The measuring unit includes several sensors that measure blood volume and its rheological properties. These sensors can be different, for example, pressure sensors, ultrasonic sensors, temperature sensors, etc.

The suction device is a vacuum system that draws blood from the patient's blood vessels. This avoids errors associated with inaccurate blood volume measurements due to its fluidity and viscosity.

Hemoretractiometry is widely used in medicine to diagnose various diseases, such as thrombosis, atherosclerosis, varicose veins, etc. It can also be used in surgery to assess the condition of blood vessels before surgery.

However, like any other medical device, a hemoretraction meter has its drawbacks. For example, it can be expensive and require special training to work properly. In addition, if the hemoretraction meter is used incorrectly, it can harm the patient's health.

Hemoretractiometer (Latin haemorrhagia “bleeding” + Greek μετρέω “measure, determine”) is a medical device used to measure the degree of blood loss during surgery.

A hemoretraction meter is used in surgery to determine the amount of blood loss during various surgical procedures, such as operations on the heart, lungs and other organs. It consists of two parts: one part is attached to the patient's skin, and the other part is attached to the surgical instrument that is used during the operation.

When the surgery is completed, the doctor measures the amount of blood remaining in the hemoretraction meter and compares it to the amount of blood that was lost during the operation. This allows the doctor to assess the degree of blood loss and take measures to compensate for it.

Hemoretraction meters come in different types, depending on how they are attached to the patient's skin and what instruments are used to perform the operation. For example, there are hemoretraction meters for operations on the chest, abdomen, brain and other parts of the body.
