With the negative pressure blood collection lancing device, glucose patients daily needle without pain.

Diabetes is very painful, a large part of the reason is that some patients need to undergo very strict blood sugar management, such as self-blood sugar management of type 1 diabetes patients, blood sugar is measured 7 times a day (three meals before, after and before bed), if the fingertip blood is collected, that is, finger pricking 7 times a day. Even for people with type 2 diabetes, getting a puncture once or twice a day is essential, making blood collection a painful experience.

The traditional method of blood glucose monitoring is to collect the blood at the end of the patient’s finger, and patients often have sharp tingling in the process of collecting blood at the fingertip.

Why does it sting?

This is because our human skin is composed of epidermis and dermis two parts. There are no blood vessels below the epidermis, and the distribution of pain nerves is minimal. The lower dermis can be divided into two layers, the upper one is called papillary layer and the lower one is called reticular layer. The epidermal layer of the middle finger is usually 0.3mm thick, the dermis is about 1.5mm, and the papillary layer is about 0.3mm-0.4mm thick.

Normally, the outer layer of the papillary layer is arranged in a ridge structure, and these dermal processes are supported by capillaries. Between the epidermis and the papilla are touch receptors called “Merkle cells” (arrow), where nerve endings sense touch. The lower reticular layer contains dense reticular plexus and vascular plexus.

The first thing a needle touches when it penetrates the epidermis is the Merkle cells, but that is just a tactile sensation, no obvious pain. As the needle continues to penetrate down to the reticular layer, where there is a large reticular nerve plexus and a thicker network of capillaries, the knife edge at the front of the needle will cut the nerves and large blood vessels, causing a lot of bleeding and intense pain.

How to ease the sting?

Is there a device that will reduce the sting of the blood collection as much as possible?

The answer is yes.

From the epidermal layer down to the papilla layer because there is no dense nerve bundle, so there is no pain, we can call this range the “comfort zone”, and the lower area with dense nerve plexus can be called the “pain zone”. This comfort zone is only 0.6mm deep, and the capillary processes in it are also rich in blood supply, so being able to control blood collection in this comfort zone can effectively control pain.

What is the concept of 0.6mm?

A single hair is about 0.05mm in diameter, and 0.6mm is equivalent to 12 hairs! It’s the extent to which you can’t see it from a little distance. Presumably people who have been pricked by ordinary blood collection pens have a deep understanding of it, that taste, it is really a silent, because it can not accurately take blood at 0.6mm, the speed of the spring, the strength of the finger, the swing of the needle, and a series of factors will lead to blood collection simply cannot be controlled in this “comfort zone” range.

Then relatively speaking, the ideal blood collection pen must be: the needle speed should be fast, the strength and depth should be accurate, and the blood should be collected at the superficial surface of the skin at 0.6mm, and it should be sufficiently stable.

Yasee blood collection lancing device can make the whole pen stable enough through negative pressure adsorption technology to firmly adsorb on the skin of the blood collection area. The ejection control technology accurately controls the force of the needle, and the 12-gear adjustment accurately controls the blood collection depth, so as to realize blood collection in shallow capillaries (i.e. 0.6mm). The wound is only in the epidermis and dermis, and there is almost no damage to the subcutaneous tissue. It can effectively reduce pain.

Yasee blood lancingdevice vs regular blood lancing device

1. Negative pressure adsorption technology

The needle is unstable due to jitter or other factors during blood collection, and a slight deviation of the needle will produce obvious pain, while the Yasee blood collection pen adopts negative pressure technology to closely connect the blood collection area, which can effectively remove the jitter factor and avoid the gap. More stable blood collection. In addition, negative pressure adsorption can also inhibit the conduction of pain sensing nerve to a certain extent, so as to better match the piercing depth.

2. Ejection control technology

The common blood collection pen is controlled by a single spring to draw out the needle, which is slow and easy to deviate, causing jitter or skew.

Yasee blood collection pen uses high-density rebound spring, one key excitation, fast needle, fast rebound, may have completed the blood collection when you have not returned to your mind, can effectively reduce the sting.

3. 12 speed depth adjustment

The ordinary blood collection pen has only 5 gear adjustment, while the Yasee blood collection pen has 12 gear adjustment, each gear can be lowered by 0.083mm, so the accuracy of each gear of the Yasee blood collection pen is higher, so compared with the ordinary blood collection pen, the needle depth control is more accurate, so it is easier to achieve blood collection in the subcutaneous comfort zone (that is, 0.6mm).

Therefore, compared with ordinary blood collection pens, Yasee blood collection pens are more suitable for pain-sensitive diabetic patients, which can help them reduce the psychological burden of blood collection, improve the comfort of the blood collection process, and make blood collection no longer a “painful thing to think about”.

In fact, it is not just a pen, blood sugar management is a lifelong matter of diabetes patients, good control, and ordinary people are no different, poor control will gradually cause damage to the body organs until the loss of treatment opportunities. Perhaps many sugar friends feel that the pain of the needle in blood collection is the most important reason for him to be unable to monitor blood sugar every day, and Yasee blood collection pen can give sugar friends more choices, so as to better and more comfortable to walk the road of blood sugar management.
