Abstract
The invention relates to an improved type detection card of a portable type biochemical detector, which aims to solve the problems in the background technology that waste liquid to be detected needs to be conveyed to a container outside a card through a waste liquid pipe, so that the cost is increased and the operation is inconvenient; a sampling opening has no connection sealing structure, so that sealing cannot be formed when a sample to be detected is injected by a standard sampling needle tube and the detection result is influenced. Aiming to solve the problems, the improved type detection card is technically characterized in that a detection region on the detection card is also communicated with a waste liquid storage region by a liquid path. The improved type detection card is applied to the portable type biochemical detector.
Description
Technical field: the present invention relates to medical detection means, be specifically related to the test card of using on a kind of improved portable bio-chemical detector.
Background technology: clinical biochemical check is that Medical is diagnosed requisite means.At present biochemical investigation is generally carried out in hospital, examinee's blood or other body fluid biochemistry detection center that will be sent to hospital, and testing result needs the long period to obtain.Although the testing result at hospital's biochemistry detection center is considered to accurately and reliably, but, the detecting instrument at hospital's biochemistry detection center is larger, be difficult for moving, and needs professional to operate, and carry out immediately detecting beyond can not be at hospital's biochemistry detection center.Yet, under many circumstances (such as: the occasions such as field, first aid, operating room), need to beyond the biochemistry detection center of hospital, carry out immediately detecting, to can in time the state of an illness be judged and be taked medical measure.Thus, produced portable biochemical detecting instrument.This instrument volume is little, be easy to carry, simple to operate, testing result is accurate.The representative products of this quasi-instrument is hand-held series vim and vigour, electrolyte, the bio-chemical detector of i-STAT company.The basic structure of the test card that this quasi-instrument configures is: injection port set on substrate is communicated with pack buried district, detection zone by liquid road, detection zone is in abutting connection with sensor electrode contact district, the sensor electrode array of electrode slice is positioned at detection zone, and the electrode contact that electrode slice exposes contacts with the circuit contact in portable biochemical detecting instrument, reagent bag is arranged in pack buried district, pack arranges spicule in buried district, substrate surface sealing overlay film.Existing problem: the one, detect waste liquid and need to by sewer pipe, be transported to the container of the outer configuration of card, increase cost, operation inconvenience; The 2nd, injection port is without connecting hermetically-sealed construction, and standard sample introduction needle tubing injects while detecting sample, cannot form sealing, affects testing result.
Summary of the invention: object of the present invention is exactly the test card of using on a kind of improved portable bio-chemical detector of proposition, the following problem existing to solve background technology: detect waste liquid and need to be transported to by sewer pipe the container of the outer configuration of card, increase cost, operation inconvenience; Injection port is without connecting hermetically-sealed construction, and standard sample introduction needle tubing injects while detecting sample, cannot form sealing, affects testing result.Solving this technical problem adopted technical scheme is: the test card of using on a kind of improved portable bio-chemical detector, injection port set on substrate is by liquid road and pack buried district, detection zone is communicated with, detection zone is in abutting connection with sensor electrode contact district, the sensor electrode array of electrode slice is positioned at detection zone, and the electrode contact that electrode slice exposes contacts with the circuit contact in portable biochemical detecting instrument, reagent bag is arranged in pack buried district, pack arranges spicule in buried district, substrate upper and lower surface sealing overlay film, it is characterized in that detection zone continuation is communicated with waste liquid memory block by liquid road.Wherein, injection port matches and seals by screw-threaded coupling with standard sample introduction needle tubing.Injection port opening is upwards communicated with upper surface of base plate Ye road after the overlay film of base lower surface again.Sealing overlay film arranges vent port at the position of waste liquid memory block.Waste liquid memory block forms some cavitys of turning back to increase its liquid storage amount.Waste liquid memory block forms some cavitys of turning back, and fills adsorption cotton to prevent waste liquid side leakage in cavity.
The beneficial effect that the present invention and background technology comparison have is: owing to adopting above-mentioned technical scheme, increased waste liquid memory block in test card, made to detect waste liquid and be directly discharged into waste liquid memory block in card, without other configuration card outer container again, cost-saving, easy and simple to handle, raise the efficiency.Meanwhile, the improved hermetically-sealed construction of injection port, injects while detecting sample standard sample introduction needle tubing, forms with it sealing, guarantees that testing result is accurate.
When detecting, first test card is inserted to portable biochemical detecting instrument device, instrument can carry out self check the sensor array position to test card, be that detection zone is heated to 37 ° of C, if all are normal, the starter gear that excites on instrument can be pressed the pack buried district in test card, and pack is punctured, reagent (being titer or calibration solution) enters the detection zone of test card and contacts with sensor array, and this process is activation and the calibration process of sensor array; After calibration process finishes, instrument can provide prompting and inject blood or other sample to be detected, at this moment operator inserts the sample introduction needle tubing that blood or other sample are housed the injection port locking of test card and inject sample in test card, when sample is by detection zone and arrive after assigned address, sample injects and stops; Detect and start, after detection finishes, instrument can provide to point out to have detected and can take out test card, and the software for calculation of instrument internal can carry out the index concentration every to be measured of calculation sample and show or print by the electric signal of comparative sample and titer (calibration solution).
