The Applications of Cashier Paper to the Hospitals
The types of medical recording paper:
According to the uses, the medical recording paper can be divided as laboratory recording paper and the recording paper for clinical diagnosis and wardship.
According to the natural classifications, the medical recording paper can be divided into five different types.
1. Common paper: it is often used in recording EEG, EMG, etc.
2. Thermal paper: it is processed by thermal coating, which is used in cardiogram and fetal monitor, etc.
3. Colloid paper: it is alike to thermal paper, whose upper side is coated with colloid, commonly used in B-ultrasonic etc.
4. Computer paper: one side of the paper is coated with chemical materials, which is suitable to be used in laser or colorful ink jet printer.
5. Carbon paper: it is coated with silver and gray carbon raw materials which use carbon pens to make notes, regularly applied in recording PF.
'The brief introduction of medical recording paper:
The laboratory recording paper is mainly based on medical thermal paper which is widely used in medical laboratory, clinical laboratory and all kinds of biochemical analysis in laboratories. Its working principle is similar to the well known copy paper and fax paper of cashier paper used in hospitals. However, the distribution of heat layer is more even and finer, so its price is higher than theirs.
On the basis of the specific scope, the clinical diagnosis, monitoring and recording paper can be subdivided into: ECG (for ECG, treadmill monitors, etc.); fetal monitoring paper (for fetal monitor); EEG ( for electroencephalography, electromyography, evoking potentials); B type paper (for ultrasound printer that is black and white and colorful and computer printer). The working principle is same with laboratory recording paper (medical thermal paper), but according to different requirements on different monitor, to overprint varied charts in order that the clinicians can determine the conditions.
The requirements for quality of hospitals to medical recording paper and the reasons:
The thickness of paper should be appropriate and the surface of the paper should be smooth enough, as well as the charts are printed clearly and have no phenomenon of dipping. For special case, the paper must have sufficient time for graphic preservation. The reasons are: if the thickness of paper is not proper, it will cause the graphic distortion, affecting the judgement of doctors; if the surface of paper is not smooth, it will lead the printed graphic lines to be not direct, influencing the judgement of doctors and damaging the print head at the same time; if the forms are not printed clearly, directly having an impact on doctors' judgement; if there is a phenomenon of dipping, the graphic lines will become blurred, making the doctors can not determine the conditions of patients; as for special cases, it there is no enough time for graphic preservation, it will make it impossible for the hospital to preserve the cases and to study them for a long time.
