Abstract

Two ports of a test tube bin are arranged on the top surface of the crate of a blood mark rechecking instrument. A test tube clip mechanism is arranged under the ports of the test tube bin. A bar code scanner is fixed on the upper part of the back of the crate. An infrared defection probe is installed on the wall surface of the test tube bin. A hand-held bar code scanning gun is installed on the lateral face of the crate. After the infrared defection probe detects that the test tube clip mechanism clips a test tube, the bar code scanner starts to scan, recheck and intercompare. The manual hand-held bar code scanning gun rechecks the mark of a blood bag. If the mark is wrong, a warning is provided. The blood mark rechecking instrument has the advantages of ingenious idea, simple structure and low cost, is provided with functions of automatic identification and recheck marking, and sends out warnings for the recheck results of different marks. Rechecked data are accurate and reliable. Mark error between a blood sample and the blood bag can be effectively prevented, and damages on the blood quality caused by the mark error between the blood sample and the blood are effectively avoided. The blood mark rechecking instrument can be convenient to use and carry and is applicable to blood stations and hospitals.

Description

Blood sign checking instrument

Technical field

The present invention relates to identify automatic identification equipment, particularly relate to the blood sign checking instrument of the identification check that identifies on a kind of test tube blood sample sign and the blood bag.

Background technology

Blood is the ingredient that body weight for humans is wanted, and the blood transfusion therapy is one of critical treatment means of rescue patient life.There is thousands of patient in the whole nation because the use of safety blood obtains living hope again again every year.Ton blood surplus only Liaoning Province just needs 80 every year, nearly 300,000 people participate in voluntary blood donation, fail with blood or various blood component for nearly 500,000 person-times, therefore transfusion safety is directly connected to the life security of extensive patients, obtain the great attention of country and administrative department of public health, also be subjected to the extensive concern of medium and society.In the chain of blood safety quality assurance, the sign of blood preparation and blood itself is an initial link, it also is an extremely important link, in case blood preparation and blood sign are wrong during blood collection, do not accomplish corresponding one by one, so later link no matter control how strictness is also of no avail, will constitute greatly harm to blood quality.Owing to there is not corresponding apparatus to use, the blood station can only be strengthened manually checking of specimen sign from aspects such as optimizing of staff training and rules and regulations at present, to avoid identifying wrong generation.But manually checking one is that efficient is not high, and in addition, the human eye that works long hours easily produces fatigue and causes error.

Therefore the blood sampling personnel of blood station urgently wish to have the automatic identification of a kind of energy, the simple again blood sign checking instrument of operation.

Summary of the invention

Purpose of the present invention is exactly at present blood station blood sign to be lacked the device of checking automatically and a kind of blood sign checking instrument of automatic identification of simple to operate and rate of accuracy reached to 100% is provided.

The technical scheme that adopts is:

Above-mentioned test tube clamp mechanism is set to two covers, is installed in the both sides in two test tube storehouses respectively.

Above-mentioned test tube clamp mechanism, can comprise test tube pipe clamp, pole, two both sides that are positioned at middle part, test tube storehouse that the test tube pipe clamp is relative, the lower end of two test tube pipe clamps is separately fixed at the upper end of two poles, the middle part of two poles connects with bearing pin is movable, the bottom of two poles is respectively arranged with a pin, two pins are installed in respectively in the notch that horizontal connecting plate two ends are provided with, laterally connecting plate is fixedlyed connected with the electromagnetism connecting rod, the electromagnetism connecting rod is connected with the moving iron phase of electric magnet, and magnet spool is connected on the outfan of circuit controller with connecting wire.

The side of above-mentioned cabinet pedestal is provided with hand-held bar code scan rifle socket, is connected with the hand-held bar code scan rifle.Blood preparation checking instrument service routine:

1) before the blood sampling bar code is sticked on test tube and the blood bag, start power supply subsequently, blood preparation checking instrument complete machine drops into operate as normal;

2) test tube is put into the test tube storehouse;

3) send instruction to barcode scanner after the infrared detection head in the test tube storehouse detects test tube;

4) scanning device begins scanning automatically, if leave two test tube specimen, barcode scanner also can scan respectively automatically;

5) retained data behind the end of scan; When the bar code of two blood samples is inconsistent, send caution sound, wait to find the reason problem to solve after, barcode scanner rescans, until the bar code unanimity of two specimen;

6) leave and take blood sample;

7) use the bar code on the hand-held bar code scan rifle scanning blood bag after blood sampling finishes.

8) if the bar code on the test tube specimen is consistent with bar code on the blood bag, test tube clamp unclamps automatically; Bar code as test tube specimen and blood bag is inconsistent, machine alarm, and test tube clamp does not unclamp, and test tube does not be presentable.

With specimen information such as acquisition time, leave and take quantity, bar code number etc., be stored in the instrument in order to for future reference also printable come out.

The present invention is skillfully constructed, and is simple in structure, with low cost, the data of checking accurately, reliable, standard blood sampling, retain the rule of operation of specimen and labeling bar code; Can effectively prevent blood preparation in the test tube and the sign mistake between the blood bag, avoid because of identifying the wrong harm that brings to transfusion safety.It is very convenient that this blood sign checking instrument uses, carries.Need to prove that under the prerequisite that does not change present principles, can also make some changes or distortion to the present invention, this belongs to protection scope of the present invention equally.
