Blood circulation equipment refers to devices manufacturers and medical experts use to expand, contract and manipulate blood vessels and organs for surgical and medical treatment. With innovation and advancement in the health sector, the equipment's type, function, and purpose vary greatly.
However, blood circulation supplies and restoration tools have some of experts' and their operational settings' most generic and non-generic aspects.
Hence, there are various types of blood circulation equipment based on what the equipment is intended to do, the operation/care specifics, and the people it targets. Here are some of the most common featured items:
Artificial blood vessels
Artificial blood vessels are used to replace or repair damaged blood vessels. They are commonly made from flexible synthetic materials such as polyurethane, polytetrafluoroethylene, polyester, and silicone rubbers, and bioplastics. Bioplastics are petroleum-derived plastics that have been chemically treated to mimic the original blood vessel composition.
Heart-Lung Machines
The heart-lung machine takes over the pumping function of the heart and the gas exchange function of the lungs during cardiovascular surgery under anaesthesia and aseptic conditions. They work by withdrawing blood from the patient's body through a venous cannula into a collecting reservoir known as a cardiotomy reservoir that contains a liquid known as cardioplegic solution.
Dialysis Machines/Artificial Kidneys
These are also known as external kidneys through which blood is passed in order to remove toxins, excess water, and unexpended metabolites when the patient suffers from renal failure. It consists of a pair of devices termed dialyzers that are semipermeable membranes used to allow passage of toxins and other substances from blood.
Angiography machine
The angiography X-ray machine is used in vascular surgery to observe blood flow, locate, identify, and characterize vascular diseases and other conditions. An angiograph is a special X-ray machine used to take pictures of blood vessels. It uses a special dye, sometimes called contrast medium or angiogram dye, injected into the blood vessels to make them show up on the images that are taken.
Cochlear implant
A cochlear implant is a small, complex electronic device that can provide the sense of hearing in people who have severe to profound hearing loss. It bypasses damaged hair cells in the cochlea to stimulate the auditory nerve directly, sending signals to the brain.
The primary purpose of blood circulation tools is to give blood or medicinal product an avenue within a living body for surgical and therapeutic interventional medicines. They also help medical practitioners understand how the blood circulates by providing a basis to measure factors affecting it.
They allow healthcare professionals to observe and interact with specific body parts and systems without risk. They can manipulate blood vessels and organs in a way that directly or indirectly facilitates healing and recovery, which is the main focus.
Some general functions of blood circulation equipment include:
Moreover, every blood circulation tool is uniquely designed with some analogue to the previous ones and tailored with precision to suit a particular medical need. They are made of good-quality material for optimal performance. The equipment's characteristics can be further analyzed by examining the various materials traditionally employed to make them.
The aspect of material composition involved is very crucial. Historically, metals such as copper, aluminium, stainless steel, and other sturdy construction materials have been used to construct external equipment like the heart-lung machine.
Today, soft, flexible materials like silicone rubber, polyurethane, and polytetrafluoroethylene are employed to make artificial blood vessels because they more closely mimic the feel and movement of genuine blood vessels.
In ceramically and polymer-derived compacts known as bioplastics, the creators deliberately try to exclude some sources of plastic derived from petroleum. This is to ensure that the materials are not only impactful but also sustainably sourced and whose usage impact on health is at worst benign.
Surroundings and space where blood circulation equipment is used fit into one of its intended operational purposes. Here are the most common scenarios where this equipment can be found:
Surgical procedures
Any form of surgery that requires blood vessel manipulation, artificial device implantation, or body section perfusion usually requires blood circulation equipment. Cardiovascular surgery, such as heart repair, artery reconstruction, blood clot removal, and heart-lung machine example, is a typical surgical intervention where blood circulation tools are indispensable.
Diagnostic interventions
Angiography, myelography, and any other perfusion-based medical examination that observe blood and CSF dynamics will necessarily rely on blood circulation equipment. These interventional diagnostic imaging procedures are typically performed under fluoroscopic or radiographic guidance within the confines of specially designed angiography suites that ingeniously couple X-ray technology with fluid dynamics study competencies.
Therapeutic interventions
Blood circulation equipment is used in various therapies, such as dialysis in renal patients, intra-arterial injection of drugs directly into the target area, and blood transfusions, where the whole blood or components thereof are infused back into the victim.
Research and laboratory settings
In experimental contexts, blood circulation equipment makes a perfect research instrument. There are topics like bioengineering artificial devices, pharmacology, radiology researches, and even understanding circulation dynamics.
Emergency care
In blood circulation devicebased compartmentalization, first aid, trauma management, and critical care of victims usually involve tools that navigate or mimic normal blood circulation. These include external blood pressure monitors, venous access sets, intra-arterial blood warmers, and transfusion sets.
While choosing blood circulation equipment, several criteria come into play, and filling them can go a long way toward making the right choice. These aspects include the purpose for which the equipment is needed, the operational conditions, and the profile of the individuals using the equipment. Below are the key factors, along with some use cases:
Medical needs
Consider the pathology the end-users work with or treat. For vascular or cardiovascular problems, heart-lung machines and artificial blood vessels help. Doctors dealing with kidney complications rely on dialysis machines. Angiography machines are preferred in facilities that handle vascular diseases regularly.
Technical specifications
Focus on the equipment specifications, quantity, and quality. Go for tools with various operational features. For instance, machines equipped with hybrid angiography, intracardiac echocardiography, or intraoperative fluoroscopy are better than simple X-ray machines.
Certifications and standards
Make certain the option you settle on adheres to Quality Assurance norms and has the required QA accreditation. Only select blood circulation tools that comply with medical governing bodies' requisite regulations to suit their purpose. Categorical care goes into such certification to ensure that equipment manufacturers prioritize user safety and effectiveness.
Budget considerations
The amount allocated for blood circulation equipment procurement will depend on the available budget. Although financial constraints must be taken into consideration when making a decision, the importance of safety and effectiveness cannot be stressed enough.
Blood circulation equipment is used to manipulate blood vessels and organs for surgical and therapeutic purposes. It helps observe, repair, or replace damaged vessels, monitor blood pressure, or provide circulation system support during surgeries.
When choosing blood circulation equipment, healthcare professionals consider the quality, safety, and effectiveness of the devices depending on the uses the facility intends to use them and their spending capacity. Such choices are made, and the prospect is enhanced by taking into account the certification, purpose, and technical specifications concerning the medical conditions treated and the effectiveness of the envisaged interventional medicine in question.
Instruments like artificial blood vessels are made from soft, flexible materials like silicone rubber, polyurethane, and polytetrafluoroethylene due to their ability to mimic the properties of natural blood vessels. External equipment may still incorporate metals like stainless steel, aluminium, and copper.
Yes, blood circulation equipment is designed to be used safely and effectively in emergency medical situations, such as trauma care and critical illness. Specialized design features ensure rapid deployment, ease of use, and robustness under the pressure of emergency conditions.
