Perfusion device

A perfusion device is a device for performing perfusion, i.e. the passage of fluid through blood vessels or organ cavities. Perfusion is used in various medical procedures, such as hemodialysis, hemosorption, plasmapheresis, lymphosorption, organ and tissue transplantation.

Perfusion machines may have different designs and functions, but they all perform the same task - pass fluid through a system of vessels and membranes to cleanse the blood or replace it with another fluid.

Perfusion devices can be made in different shapes and sizes, but usually they consist of the following main components:

– A pump for transferring liquid, which can be electric, pneumatic or hydraulic.
– Membranes or filters that allow fluid to pass through the vascular system and remove unwanted impurities.
– Connectors and hoses for connecting the pump to the vascular system.
– Controller for pump control and monitoring of perfusion parameters.

The most common types of perfusion devices include hemodialyzers, plasma filters, hemosorbents and other blood purification devices. A hemodialyzer is used to remove toxins and metabolic products from the blood, and a plasma filter is used to separate the blood into plasma and formed elements. Hemosorbent is used to remove certain substances from the blood, such as toxins or allergens.

In addition to medical procedures, perfusion machines are also used in experimental research, where they are used to culture cells or organs in an artificial environment. In this case, the perfusion device acts as a circulatory system, which provides the cells with the necessary nutrients and removes waste.

Thus, the perfusion apparatus is an important tool in medical practice and experimental research. It allows for various procedures for blood purification and organ cultivation in artificial conditions.

A perfusion device is a special medical device designed to perform operations or artificially maintain the functions of important organs and systems of the body. It transports blood into the vascular system and then back. Perfusion devices are used for various medical procedures such as hemodialysis, organ transplantation, cardiopulmonary bypass, tissue culture. In this article we will look at the basic principles of operation of the perfusion apparatus, its purpose and areas of application.

Perfusion devices allow various medical procedures to be performed under artificial circulation. They ensure the maintenance of vital body functions and help improve patient outcomes. These devices are designed for a variety of procedures, including the treatment of kidney damage, heart replacement, organ transplantation, and the use of a heart-lung machine during open-heart surgery.

Perfusion refers to the movement of blood from one vessel

*Perfusion device* is a device that is used to pass fluid through different cavities and vessels of the human body. The device is widely used in medicine for performing various operations, treating various diseases, as well as for growing tissues and organs of the body. Because of its versatility, it is used both in hospitals and at home.

The main functions of a *perfusion apparatus* are to control the rate of supply of liquids, the pressure inside the vessels and the temperature of the contents. To achieve this, the device is equipped with a variety of sensors and auto-regulation mechanisms that allow the patient’s resources to be processed accurately and safely.

Depending on the specific patient's task, the *perfusion device* can be used for both internal and external applications. It allows the passage of blood, nutrients, medicines, etc. inside the organism or body.

One of the main advantages of using perfusion machines is their safety and accuracy. They allow you to control all parameters of the procedure (blood flow rate, temperature, pressure), which helps to avoid possible injuries and damage to the patient. Moreover, they can function simultaneously with other medical devices (for example, X-ray or ultrasound machines for monitoring a patient's condition) without interfering with each other.

Additionally, *perfusion* plays an important role in laboratory research, especially in biomedical engineering. In this case, special perfusion devices and solutions are used to simulate the processes of blood circulation and diffusion of drugs in tissues. Control of perfusion parameters allows precise measurements of the concentrations and rates of certain chemicals in the bloodstream and improves the quality of experimental data and the accuracy of inferences made about the structure and function of cells in the body.

Experts call *perfusion* an effective therapy and consider it safer than other bloodletting methods. Perfusion is performed using a variety of devices, but the overall process is to remove unwanted substances from the body using medications and saline or whole blood. Thanks to the transfusion, the blood-sucking system receives more oxygen, nutrients, glucose, important microelements, nucleic acids, and the heart continues to function properly in conditions of less blood supply. Some devices automatically determine the content of certain substances (proteins and bilirubin) in the blood from urine and analyze the data. This helps to create an individual treatment regimen, evaluate the effectiveness of the course already completed and select the dosage of the next one. Thus, perfusion can stimulate the restoration of damaged cells and promote rapid healing.
