Portable Blood Glucose Meter

Introduction

Diabetes is a chronic, lifelong disease that develops progressively. If it is not diagnosed and treated in time, it can cause a variety of complications. Common complications include nephropathy, retinopathy, neuropathy, diabetic foot, hypothyroidism, etc. Scientific and standardized monitoring of blood sugar is the key to mastering the condition of diabetes. In the treatment of diabetes, blood sugar monitoring can help understand the changes in blood sugar, which helps guide patients to correct their diet and lifestyle, and also helps doctors adjust the treatment plan. Strict blood sugar control can effectively reduce the risk of complications in diabetic patients. Blood sugar monitoring is the basis and important part of the intensive treatment plan. Patients with poor blood sugar control need to monitor their blood sugar at least 4 times a day. Therefore, blood sugar monitoring is very important. By strictly controlling the level of blood sugar metabolism, the occurrence and development of diabetic complications can be significantly reduced, providing a reference for clinical treatment.

With the advancement of science and technology and the development of laboratory medicine, rapid blood sugar meters are currently one of the most widely used instruments for self-monitoring in hospitals and families at all levels because of their small size, easy to carry, simple operation, and quick report generation.

How to use a portable blood sugar meter correctly?

Portable blood sugar meters can measure blood sugar very easily and quickly, and are also very convenient to use.

First, we need to prepare the relevant items, including blood glucose meter, test strips, alcohol cotton pads, disposable blood collection device, and pressing cotton swabs.

The first step is disinfection. Wipe your fingers with alcohol cotton pads and then dry them.

Here we need to remind everyone that when measuring blood sugar, only alcohol can be used for disinfection, not iodine. Because iodine preparations will destroy some enzyme components on the test strips during contact with the test strips, resulting in inaccurate blood sugar measurement. In addition, alcohol evaporates very quickly. After disinfection, the skin can dry quickly without waiting too long.

The second step is to insert the test strip. While waiting for the skin to dry, you can insert the test strip. As long as the test strip is inserted, the blood glucose meter will start. When we see a blood drop symbol on the blood glucose meter, we can collect blood.

The third step is blood collection and testing. Press the blood collection device on the non-finger pad of the finger, and then drop the blood on the test strip. It only takes a few seconds for the blood sugar data to come out quickly.

Some friends may ask, why do we avoid the finger pads when collecting blood? This is because the fingertips are very sensitive, and it hurts when they are pricked. When picking up things, the highest part of the fingertips is used to touch the objects, which will always feel very painful. So we try to choose the positions on both sides of the fingertips for collection, and any finger can be chosen.

Step 4. After collection, press with a dry cotton swab to stop bleeding.

How to master the frequency of blood sugar monitoring?

The frequency of blood sugar monitoring is different for different diabetic patients.

For example, for patients treated with insulin, we recommend that blood sugar monitoring be performed every day.

If blood sugar reaches the standard, it is recommended to measure blood sugar 2-4 times a day. If blood sugar does not reach the standard, it is recommended to measure more than 5 times a day.

Then the time point for measuring blood sugar needs to be selected according to the type of insulin used by the patient. Some patients take one injection a day, some take two injections a day, and four injections a day are required for intensive treatment. At the same time, we also need to consider the superposition of drugs.

For example, when using premixed insulin, we will recommend that patients measure fasting blood sugar before dinner, before bedtime, and in the morning to see if hypoglycemia occurs.

For patients who choose oral medications to treat diabetes, we recommend monitoring three days a week.

If the blood sugar is up to standard, it is recommended to measure blood sugar 2-4 times a day. If the blood sugar is not up to standard, it is recommended to measure it at least 5-7 times a day to see which time period is not up to standard, before three meals, after three meals, and before going to bed, which is exactly 7 times in total.

In short, different patients have different frequencies, and we need to monitor blood sugar under the guidance of professionals.

What is the blood sugar control considered up to standard?

The target value of blood sugar is usually determined according to the actual situation of the patient. When setting the target value, it must be individualized.

For adults, it is recommended that fasting blood sugar ≤7mmol/L and blood sugar ≤10mmol/L 2 hours after a meal.

In addition, we have to think of some special situations, including individual differences of patients and different degrees of diseases.

For example, many elderly people will have cardiovascular and cerebrovascular diseases, or accompanied by some other problems. We are more worried about hypoglycemia, so the target value for the elderly needs to be looser. Fasting blood sugar ≤7.8mmol/L, blood sugar ≤11.1mmol/L 2 hours after a meal, the target value is reached.

If it is a patient with gestational diabetes, blood sugar control should be stricter. Generally, we require fasting blood sugar ≤5.3mmol/L and ≤6.7mmol/L 2 hours after a meal. When controlling, in addition to high values, we must also pay attention to low values. Nighttime blood sugar cannot be lower than 3.3mmol/L.

For children, we emphasize that children's blood sugar must not be too low at night, because children's blood sugar fluctuates greatly, especially in adolescence, so it is recommended that nighttime blood sugar should not be higher than 11.1mmol/L to avoid the negative impact of hypoglycemia on children's growth and development.

Finally, everyone must remember that blood sugar must not be controlled as low as possible. Each of our different diabetic patients must set a reasonable target value under the guidance of a professional doctor and monitor it.

Precautions

1.Do not place it in direct sunlight or hot and humid places, do not drop the machine to the ground and avoid collision, and do not disassemble, repair, or modify the body or wristband of the sphygmomanometer by yourself.

2.The blood glucose meter must be used with the same brand of test strips and cannot be mixed. Do not repack the test strips and use them within 3 months after opening (note that it is within the validity period). Some blood glucose test strips are different from each batch. Before changing, you need to enter the barcode number of the new test strip into the instrument, otherwise it will affect the test results.

3.Do not use mobile phones or other devices that generate electromagnetic interference near this product.

4.Please use No. 7 manganese or alkaline dry batteries (2 pieces), do not use other batteries, and do not mix old and new batteries or batteries of different types! Please remove the dry batteries when not in use for a long time (more than 1 month).

5.Disinfect with alcohol before testing, and wait until the alcohol is completely dry before taking blood to prevent alcohol from mixing into the blood. Do not use iodine to disinfect, because iodine will react chemically with the test agent on the test strip, affecting the accuracy of the test.

6.Patients make self-judgments based on the measurement results. Self-treatment is very dangerous. Do not self-diagnose or change your medical treatment behavior without the permission of the doctor.

7.The amount of blood collected must be sufficient to completely cover the test area of the test strip. When taking blood, if you find that the amount of blood is small, you cannot squeeze your fingers, otherwise it will mix into the tissue fluid and interfere with the blood sugar concentration. To ensure that the amount of blood collected is sufficient, you can soak your hands in warm water before, and then hang them down for 30 seconds. In addition, press the needle once before ejecting it to avoid piercing too shallowly.

8.Do not touch the test strip when your hands are wet or dirty. After taking out the test strip to be used, please immediately close the can lid and use it within the validity period. Keep the test strip in a dry and dark place.
