Handheld Coagulation Analyzer
Model：LA-100
USER MANUAL
`
1 / 17
Preface
Respected customers:
This manual is suitable for handheld coagulation analyzer and used clinically with blood coagulation
test strip for blood coagulation test of human samples.
The sample flows to the reaction area due to the capillary force when the blood sample is dripped into
the test strip. Each reaction interval contains a pair of metal electrodes. The handheld coagulation
analyzer generates a constant voltage output to the metal electrode. In the reaction area, the blood
sample combine with the immobilized reagent to induce a series of biochemical reactions to start to
coagulate. The device monitors the process of blood coagulation and the change of current signal, then
generates the coagulation curve with the change of current and time. In the coagulation curve, the
current signal rises and reaches its peak at the beginning due to the connected two electrodes with the
flow of the sample. With the activation of coagulation factors during the process of coagulation and the
conversion of fibrinogen into fibrin, the curve changes accordingly and produces corresponding
characteristics (height, area, etc.). The supporting device analyzed the coagulation characteristics of this
curve and calculate the time of the coagulation item of the sample.
All the consequences caused by the failure to use the product in accordance with the user manual shall be
undertaken by the user!

14. Electromagnetic compatibility
Electromagnetic compatibility (EMC) is defined as a product, device, or system in normal work in its
electromagnetic environment and not to constitute an unsustainable electromagnetic disturbance to
anything in the environment.
Anti-EMI is the ability of a product, device or system in normal work in the presence of electromagnetic
16/ 17
interference (EMI).
Handheld coagulation analyzer is designed and manufactured according to the existing standards of
electromagnetic compatibility and related requirements. Using an analyzer in the presence of an
electromagnetic field may result in reduced performance such as repeatability or accuracy. If this
phenomenon occurs frequently, it is recommended to check the analyzer's use environment to identify
possible sources of disturbance. The disturbances may come from other electrical devices used in the
same room or neighboring rooms, or from mobile phones, walkie-talkie, portable and mobile RF
communication equipment, or from nearby radio equipment, television or microwave transmission
equipment. If EMI interferes with the analyzer, it may be necessary to move the analyzer to another
location or take the appropriate EMI suppression measures.
The analyzer conforms to the requirements of the emission and anti-interference stipulated in national
standard GB/T 18268.It is recommended that the electromagnetic environment be evaluated before the
equipment is used.
14.1Prompt
The equipment is designed and tested according to the device of class A in GB4824. The device may cause
radio interference, and protective measures should be taken in the home environment.
