Features of laboratory equipment

Today, laboratory equipment for medicine enjoys increased attention and considerable demand, and this is not surprising at all.

After all, medicine and laboratory diagnostics in all its areas are developing very actively today, and this increases the demand for modern equipment and interest in it.

The higher the quality of equipment and the more modern and high-tech it is, the higher will be the effectiveness of its use and the more accurate will be the results of tests.

Relevant and in demand for today’s medical equipment is becoming scientific and measuring equipment, special furniture and utensils.

All these tools are offered by manufacturers in a very wide range and the most advanced and modern variants have a special value for the consumers, for the sake of which it is advisable to carry out a complete reorganization and re-equipment of the medical center or laboratory.

However, it is not always easy to find everything you need and even get information about the latest developments, as well as to submit it.

And yet, these difficulties do not imply the need to abandon modern advances, because it is for their implementation that special events, such as exhibitions, are organized.

The exhibition is convenient and expedient, it is a chance to get acquainted with the necessary and important solutions, especially when it comes to such a broad topic.

Nowadays, laboratory equipment for medicine is being chosen more and more carefully, and the standards for it are getting higher and higher. At the very least, it has to be comprehensively efficient, both analytically and diagnostically.

Requirements are increasing in terms of safety and environmental compatibility, hygiene and applied technology, cost-effectiveness, and so on.

Multifunctional technical equipment is becoming the most expedient solution for many laboratories and medical centers, and today it is possible to find samples that can be used for various kinds of research as well as for medical purposes, i.e. directly for treatment.

However, at the same time, despite the constant search for high-tech solutions, there is also a huge demand for the simplest equipment, without which it is impossible to perform basic works – these are disposable and reusable dishes and measuring instruments of mechanical type.

However progress is not helpless even over these devices, they are actively improving, using more stable and durable materials that are immune to high temperatures and aggressive substances.

Laboratory equipment that is used for medical purposes may have a different focus of application, and, considering its classification, first of all, it is worth noting the dishes and laboratory glass is measured and unmeasured, specialized dishes.

Laboratory stirrers are also very much in demand, allowing the creation of homogeneous mixtures for research or medical purposes.

Magnetic shaker becomes the most convenient and safe technical device for such purposes because it does not heat up and has no rotating elements and a significant set of functions.

Also increasingly popular are the increasingly cheap submersible versions, which stir the materials mechanically.

Modern agitators have simple and clear digital displays and do not create problems in operation.

Also popular and in demand are laboratory centrifuges, which are also needed for the widest range of diverse work.

A wide variety of devices may be needed, and fortunately, progress has made it possible to get everything you need in full – with the right approach to selecting and purchasing products, of course.

Equipment

Types of modern surgical equipment

Equipment for operating rooms and intensive care units can be classified according to their purpose:

general surgical equipment – these are surgical instruments, operating tables, apparatuses and devices used in various areas of medicine;
specialized instruments for individual surgical interventions;
auxiliary devices (sterilizers, disinfectors, etc.);
equipment for operation rooms, intensive care and general wards.

Surgical instruments, both general and special purpose, assume the following basic classification:

electrical;
ultrasonic;
laser;
radiowaves.

Electrical devices
The purpose of using electrical devices in surgery is to perform surgical interventions based on the effects of high-frequency electricity on body tissues. Such devices are used for:

surgical interventions on the chest;
treatment of gynecological, gastric and ENT diseases;
Removal of skin tumors;
Microsurgical operations on the spine and brain;
biopsy.

Electrosurgical apparatuses are in demand in gynecology, ophthalmology, dentistry and other branches of medicine.

Ultrasound devices
The use of ultrasound in surgery helps perform surgical procedures without incisions and disruption of tissue integrity. Equipment that operates with the help of an ultrasonic wave can reduce the trauma of surgery. In addition, the patient’s rehabilitation time is reduced.

Laser devices
Equipment based on laser radiation ensures sterility of tissues and their minimal damage during surgeries, guarantees minimal blood loss and quick coagulation of vessels.

Laser devices are in demand for skin and cosmetic surgery, and are effective in the fight against cancerous tumors.

Radiowave devices
It is impossible to imagine a modern medical center without radio wave surgery equipment. Radiosurgery is a method by which tissue incisions are made without deep damage. This minimizes the risk of postoperative complications.

Medical equipment: views and features

A doctor’s main tool is his or her sharp mind. But, no matter how sharp your mind is, you will perform surgeries with a scalpel or a radio wave knife. And, regardless of the sharpness of your eyesight, you will perform diagnostics with a microscope or X-ray.

In this article, we will talk about the equipment of medical practice and why the actual needs of a doctor and the legal requirements so often diverge.

One of the items we ask our clients when opening a private medical practice is a list of available equipment. Why the list of available equipment? Because in most cases, despite all the modernity of the equipment, it is likely to be inconsistent with the equipment list.

What is the equipment list in medicine?
The equipment list is the minimum set of medical equipment that a doctor should have, depending on the specialty, in a particular office (or group of offices).

So what to do if the report card establishes a minimum list of medical equipment and you need to have a product that you don’t actually need?

There is no perfect solution that would take into account both the real needs of the practice and the legal requirements. This issue can be resolved in the following ways:

to purchase outdated or unnecessary medical equipment solely to fulfill the requirements for obtaining a medical practice license (you will be surprised how much such equipment is in the offices and storerooms of medical institutions and offices);
not to purchase certain products if their functionality is duplicated by other available equipment (in this case, we recommend that you clearly state this when filling out license documents and during inspections);
rely on the understanding of officials (who actually sometimes have a medical education and can understand the principle of operation of a particular medical device) of the obsolescence or specificity of equipment or procedures and not purchase such equipment at all. In this case, as well as in the first one, there is still a risk of being denied a license, but it is higher.

We would like to clarify that outdated and unnecessary medical equipment are not always the same thing.

Doctors often understand unnecessary equipment as something that is not needed in their practice, but can be used by another doctor of the same specialty. If such equipment is on the report card, then in most cases, you still need it. Because, with some exceptions, you cannot divide your specialty as you see fit. Well, at least not by equipment.

Also, there are more modern report cards, for example, in terms of the functioning of family doctors’ offices or X-ray rooms. In such cases, there are practically no options and you have to fully staff the office.

Principle of operation of electrosurgical units

Nowadays, surgery using high-frequency electrosurgical devices is one of the modern technologies, without the use of which surgical interventions in large numbers are simply not possible. These are primarily areas of medicine such as neurosurgery, gynecology, oncology, gastroenterology and other areas of general surgery.

High frequency electrosurgery (HFES) today refers to the method of applying high frequency current to biological tissues for electrotomy and coagulation. This technique is based on the effects of high temperatures produced by the passage of high-frequency current through the human body.

During the local heating of the tissue with a special high-frequency current, the tissue is coagulated. At the same moment, protein denaturation takes place – protein tissues are coagulated, so that small vessels are coagulated, providing hemostasis. Coagulation is not only used for hemostasis. This method is also used when it is necessary to mechanically connect different tissue fragments (“weld” together vessels, alveoli, which detached from the tissue during pathological processes), to remove different tumor formations, to treat varicose veins and other diseases.

To cut the patient’s tissues, heat is used, which is released when a current of increased density is applied to them, compared to the one used in coagulation. Local application of the current allows for the release of heat, under the influence of which fluids instantly boil, resulting in the rupture of tissue near the surface of the cutting electrode. At the same time this very heat provokes coagulation of protein in the tissue and simultaneous coagulation of the tissue as it is dissected.

How electrosurgical units work
There are two ways in which electrosurgical devices work: monopolar and bipolar. In the monopolar technique, current flows through the human body and passes to the passive electrode from the active electrode. The active electrode has a fairly small working area, which is why the current of maximum density is concentrated near the electrode, which provides tissue heating. Exposure of monopolar type is used both for cutting the body tissues and for their coagulation. In some cases, the passive electrode is not used when using the monopolar method. In this case the person is placed on the ground and the second generator output is grounded, the high-frequency current passes directly through the patient’s body and is shorted to the generator.

With the bipolar method, the two generator outputs are connected to active electrodes that are combined into a single structure, a single surgical instrument. For example, this might be a bipolar coagulation forceps. When such a surgical electric tool is exposed, the distance between the two active electrodes is equal to a value on the order of the linear size of their working areas. For this reason, the current distribution takes place in the area between the electrode surfaces and the volume of the affected tissue is rather small.

Electrosurgery has a lot of advantages but also some disadvantages. If physicians do not fully follow the rules for operating electrosurgical equipment, the patient can be struck by the high frequency current. These rules include guidelines for the use of the electrosurgical unit itself, as well as for the use of the ECHF unit simultaneously with other equipment.

Today, modern medicine uses a solid number of ECHF devices, which differ from each other in their size and parameters, design features, provided modes and set of tools.

Usually, general surgery uses universal electrosurgical devices, which have a large number of different modes and a set of working tools, as well as high power output, which allows the use of these devices in various surgical interventions.
