Description

Automatic coding device and the biology sensor with automatic coding device
Technical field
The utility model relates to a kind of automatic coding device, the automatic coding device on the biology sensor of particularly using for medical test.The utility model also relates to a kind of biology sensor with automatic coding device.
Background technology
In recent years, from utilizing at first clinical labororatory's pattern detection, be attainable fast detecting at one's side to only needing in doctor's office or patient, huge variation has occured in medical health care.Disposable zymetology biology sensor is often used in the fast detecting.People utilize the catalytic action of enzyme spcificity, develop various types of biology sensors, for example, are used for the biology sensor of blood sugar test.The electrochemical method of biology sensor usually adopts anode and negative electrode is fixed on the insulated substrate, and reaction reagent covers the method on the electrode.After adding sample, redox reaction occurs in the target substance in the sample under the catalytic action of enzyme, and oxygen or electronics transmission carrier are reduced, and the oxygen that be reduced this moment or electronics transmit carrier and discharge electronics because electrode potential is forced to oxidation, cause the variation of electronics.It is exactly electrochemical determination method that such electronic variable is given the method that quantification detects target substance content indirectly.For example, US Patent No. 5120420, US5320732, US5141868 etc. have disclosed the biology sensor of the detection blood sugar of disposal type.These sensors are comprised of two plastic sheets that roll together.The formed exhaust capillary channel of this structure can be incorporated into sample inner conversion zone.Enzyme layer on sample and the biology sensor and electrode contact also react, and detecting instrument collects the reaction signal that provides on the biology sensor, and the analyte in the sample is detected.
Along with the development of technology, only just can finish the mensuration of dissimilar biology sensors with a detecting instrument.Therefore for correct detecting, the biology sensor that detecting instrument must be judged current use is the detection of carrying out which kind of type.In addition, in process of production, can there be some differences in the biology sensor between each batch, and detecting instrument must judge these batches difference of biology sensor.
US Patent No. 5366609 has been used a kind of storage key that can plug.At first the control informations such as information with type of detection information or difference between batch are stored in this storage key, during use this key is inserted in the detecting instrument, after detecting instrument reads information in the key, the signal that biology sensor is given is made corresponding correction and finally provided testing result.Each stores only corresponding one batch biology sensor of key, and this just requires the user in use, confirms whether the lot number of current biology sensor using conforms to the corresponding key lot number that stores.The design that this control information and biology sensor separate, have the following disadvantages: 1) user is when using biology sensor to detect, need to carry out the operation of two steps, namely insert the storage key and insert two steps of biology sensor, therefore use very inconvenient.2) because one of the prior insertion that the very important person is stores key, this can exist the operator to forget the possibility of this step.
For above-mentioned weak point, US Patent No. 7415285 discloses control information has been incorporated on the biology sensor, to realize only needing single stepping just can finish the function of proofreading and correct and testing.This biology sensor comprises working electrode, reference electrode and is used for proofreading and correct the comparison electrode of difference between batch.Different thickness or figure by electrode are adjusted electrode resistance value, the parameter information that different resistance values is corresponding different.But deviation can occur in the thickness of electrode and figure etc. in process of production, relatively is difficult to obtain the uniform resistance absolute value of electrode.Can cause that so the different biology sensor control informations between same batch there are differences, and cause testing result inaccurate.
U.S. Patent application US20100170791A1 discloses a kind of biology sensor, and this sensor comprises the electrode of the parameter information that records this biology sensor.Described electrode has electrode pattern and forms thereon a plurality of contacts according to described parameter information, and described parameter information is based on the resistance ratios between a plurality of contacts.This U.S. Patent application has overcome difficult in process of production acquisition and has had the shortcoming of the electrode of even resistance value.But this utility model has the following disadvantages: when needs are stored a large amount of control information, just need to have a plurality of contacts to finish the judgement task on the biology sensor, this can make detecting instrument also increase accordingly tie point, so that detecting instrument is not compatible.When the tie point quantity of detecting instrument is less than the contact of biology sensor, then detecting instrument can't work.When the tie point quantity of the detecting instrument contact more than biology sensor, then unnecessary tie point will be left unused, and both takes up space, and has also increased the cost of product.
