With the continuous popularity of thermal paper, we can see their presence in various scenes. What other unexpected uses are there? In fact, thermal paper is also widely used in medical thermal paper rolls, ECG-medical thermal paper, fetal monitoring paper, etc. they are all thermal paper in nature. The following is a detailed explanation from Guanhua paper products.
1、What is ecg medical thermal paper?
ECG-medical thermal paper drawing is a kind of processing paper used with electrocardiograph. First, a layer of carbon black is coated on the base paper as the base, and then a layer of white paint is coated to make the surface the same as the ordinary white paper in appearance. And then printed with coordinate lines. When the “hot head” of the electrocardiograph contacts the paper surface, the coating is melted and opened to show black lines, and the corresponding corrugated lines are obtained.


2、What is thermal paper?
Thermal paper is also known as thermal fax paper, thermal recording paper, and thermal copy paper. In Taiwan, it is called thermal copy paper. Thermal paper is a kind of processing paper. Its manufacturing principle is to coat a layer of “thermal coating” (thermal discoloration layer) on the base paper. Although there are more than ten kinds of chemicals used in this color changing layer, there are at least the following compounds: colorless dye, which has a wide variety, and fluorescent compounds are commonly used; Chromogenic agents account for less than 20%, and commonly used are bisphenol and p-hydroxybenzoic acid; The sensitizer accounts for less than 10% and contains benzenesulfonic amide compounds; Filler accounts for less than 50%, and calcium carbonate (fine particles) is commonly used; Adhesive accounts for less than 10%, such as polyvinyl acetate; Stabilizers such as dibenzoyl phthalate; Lubricants, etc. Therefore, the process is difficult and the technical requirements are high.

3、 Why should ECG-paper use thermal paper?
(1) Easy replacement – the paper can be replaced without opening, which is very important for medical equipment.
(2) Simple structure and high reliability – the thermal paper is equivalent to “self-contained ink”, which saves the trouble of replacing ink and paper separately. When printing, the heat source is fixed and there is only relative sliding between the paper, and the stability and reliability are guaranteed.
(3) The principle is similar — the principle of thermal printing is just the same as the principle of [the change of body surface potential with time] reflected by electrocardiogram.

4、 Application of thermal paper in medical consumables

Thermal paper is used as recording material in medical consumables and measuring systems, such as ECG drawings and B-ultrasound paper. Heat sensitive paper can be used to print electrocardiographic drawings and record patients’ electrocardiographs, which is an important basis for doctors to diagnose and analyze patients. It can be said that the progress and maturity of medicine can not be separated from the support of modern science and technology. In the past, doctors paid attention to seeing, hearing and asking, while modern scientific instruments can intuitively detect the patient’s physical condition. In addition, doctors’ rich medical experience can accurately judge the patient’s physical condition, so as to suit the medicine to the case and make diagnosis by looking at the pictures. It must be said that this is the advantage of modern medicine. Thermal paper provides drawings for the recording of advanced instruments. These drawings are also called medical paper and can be said to be an indispensable part of the process.
