Injections and blood draws have a wide range of uses and are one of the most common types of medical tests. Most blood draws take only a few minutes and are performed in a testing laboratory, or sometimes in the hospital, by a doctor, nurse or phlebotomist (blood drawer).
At its most basic level, blood collection is simple: you insert a needle into your arm or hand and draw blood. However, there are several factors that can complicate matters and increase the risk of collecting blood samples incorrectly. For example, any time you reuse needles to collect blood samples or any other medical procedure involving needles, you increase the risk of developing potentially life-threatening diseases like hepatitis C or HIV/AIDS.
If you frequently draw large amounts of blood (such as during dialysis), it is important to develop good techniques that minimize pain while avoiding injury. Because needles and blood are not really pleasant, it is crucial to have trained medical personnel and quality medical instruments.
Blood samples can be taken for a variety of reasons. Blood tests are very common in clinics, hospitals and doctors' offices around the world. Doctors commonly use blood samples to determine if there is something wrong with you and what treatment you need.
The test can be used to:
Blood collection equipment provides quick and accurate measurements of blood content, such as oxygen levels, glucose levels, alcohol levels, protein levels and more. It can also help detect diseases such as sickle cell anemia or diagnose an early pregnancy simply by analyzing the hormones in your blood samples.
Indeed, during a blood test, it is possible to evaluate the concentration of various elements that make up the blood: the quantity and quality of blood cells (i.e. white blood cells, red blood cells and platelets), various hormones, and the possible presence of proteins related to inflammation.
A blood test usually involves taking a blood sample from a blood vessel in your arm. The arm is a convenient part of the body to use because it can be easily uncovered. The usual place to take a sample is from the inside of the elbow or wrist, where the veins are relatively close to the surface.
Children's blood samples are often taken from the back of the hand. Their skin can be numbed with a special spray or cream before collection. Sampling units are recommended in this case, as well as for the elderly, as their veins are thinner than normal.
A tight band(tourniquet) is usually placed around your arm to block the blood. It tightens the arm, which temporarily slows down the flow of blood and makes the vein swell. This makes it easier to collect the sample at the puncture site. This way, a large amount of blood is collected right away and the tubes fill up quickly. Before taking the sample, the doctor or nurse must clean the skin area with an antiseptic wipe so that no bacteria or germs enter the bloodstream.
A sterile needle connected to a syringe or special container is inserted into the vein. The medical syringe is used to draw a blood sample. You may feel a slight stinging or scratching sensation when the needle is inserted, but it should not be painful. If you don't like needles and blood, tell the person taking the sample so they can make you more comfortable.
Once the sample is taken, the tourniquet is released and the needle is removed. Pressure is applied to the skin for a few minutes with a cotton ball. A bandage can be applied to the small wound to keep it clean.
Your blood is then sent to the laboratory for appropriate tests and your doctor will give you the results.
Some tests require the use of a central or peripheral venous catheter, depending on your needs. Catheterization is widely used in hospitals. It minimizes the number of injections or needle pricks during recurrent administration of products or during frequent blood sampling. Quite often, the catheter is connected to an infusion stand at one time or another by the healthcare professional for the administration of care or various substances.
Common applications of the catheter are:
The peripheral venous catheter is a long flexible tube that is inserted into a venous line. The peripheral venous catheter is often inserted into a vein in the arm or hand, which is a superficial vein in a body part. There are different types of catheters, which the caregiver or doctor chooses according to the patient and the use he or she wants to make of it. The latter is commonly used during surgery, for example.
The central venous catheter is a more complex medical device, because it leads to the superior vena cava. It is usually placed on the patient's chest or neck and can be held in place for a much longer period of time. The venous catheter is used in chemotherapy, for example, because it allows for long-term injectable treatments.
If you have everything you need to draw blood, your job will be much easier. If you don't have the proper medical instruments, chances are things won't go so well for you. Blood collection equipment comes in a variety of shapes and sizes, from an infusion bag with a needle to blood collection tubes that you can fill yourself.
To ensure that blood samples are collected correctly and efficiently, it is important to use the right equipment. You should choose the right medical devices based on your own needs as well as those of your patients. There are many types of equipment, from medical syringes to vacuum tubes to blood collection bags, each designed for different purposes and with different strengths and weaknesses.
Find everything you need for a successful blood test in the DocCheck store. We offer various sampling systems, such as Butterfly cannulas, different tourniquets, blood tubes, monovettes of different sizes and also the appropriate disinfection equipment. All this makes blood collection efficient and painless for the patient.
The procedure used to take the blood sample has no influence on the results. Various sampling systems are available on the market. Whether they are intended for sampling or parenteral injections, we offer you different types of medical needles in the DocCheck store:
The winged infusion set is a medical device for continuous intravenous injection. The DocCheck Shop also offers cannulas and adapters to ensure patient safety and protection against blood exposure accidents. Similarly, monovettes of different sizes ensure a closed system and also aim to minimize the risk of incidents while adapting to different patient typologies. These blood collection accessories as well as convenient blood collection trays and sedimentation media are available in the Blood Collection Systems category.
The variousinfusion sets we offer in the DocCheck store are intended for precise and fast venipuncture. This includes injections, infusions and transfusions. The infusion sets are ideal for less painful access to the puncture site and also minimize the risk of injury to caregivers. They are equipped with specific safety systems and meet the standards. Thus, patients and caregivers are protected.
To measure blood glucose, blood must also be drawn. In this case, the sample is taken from the fingertip. The amount of blood sample required by blood glucose meters is very small. Blood sampling for blood tests via blood glucose meters can be done quickly and easily with a good lancet and a small prick on the fingertip. No blood tube is needed. The blood is applied directly to the appropriate test strip according to the established procedure.
It is essential to follow a set protocol when developing various treatments, especially when possible contact with blood may be involved. The regular use of antibacterial soap and gel for the nursing staff is essential. Similarly, the wearing of protective gloves helps minimize the risk of a blood exposure accident. For the patient, the main risk is infectious and therefore requires very strict aseptic conditions. It is necessary to disinfect the patient's sampling site under all circumstances.
It is also essential not to forget the care to be given to waste related to care activities with infectious risks. This waste must be collected in adapted containers such as specialized needle collectors designed for the secure transport of used needles and ensuring a total seal. You will find many other medical accessories in the Hygiene & Disinfection section of our site.
In the DocCheck store, you will find all the medical instruments necessary for blood tests at attractive prices and meeting the highest standards of service and quality. In addition, we offer a variety of medical devices in the other categories of our online store, whether for diagnosis or laboratory testing. We have everything you need in the DocCheck store.
