How to use the prothrombin time tester

Prothrombin time detector is a medical device used to detect the patient's prothrombin time, and is often used to detect pre-thrombotic states. The following is how to use the prothrombin time detector:

1. Sample preparation: Before the experiment begins, place the required blood sample in a collection tube. Add anticoagulant according to the requirements of the collection tube to ensure that the sample does not contain coagulation factors. Place the collection tube in the sample tray and record the patient's name, medical record number and other relevant information.

2. Instrument preparation: Take the instrument out of the package, clean it, and put it back in place. Connect the power cord, turn on the power switch, and press the "Self-Test" button to check whether the instrument is working properly.

3. Operation steps:

a. Open the detection software on the computer and install the detection software and communication adapter according to the on-screen instructions.

b. Place the collection tube into the instrument and press the "Start" button to start the test. The instrument will automatically collect and process the sample during the test.

c. After the test is completed, the instrument will automatically calculate the patient's prothrombin time and display the result on the screen.

d. Document patient outcomes and order further treatment as needed.

4. Notes:

a. Before use, check whether the instrument and collection tube are intact. If damaged, stop using it immediately.

b. Before testing, ensure that the sample does not contain coagulation factors to avoid affecting the test results.

c. When using the instrument, the operating procedures should be followed to avoid damage to the instrument or contamination of the sample due to misoperation.

d. The test results are for reference only and further treatment should be carried out according to the patient's specific situation.
