Description

A kind of analoids

Technical field

The utility model relates to medical treatment consumptive materials technical field more particularly to a kind of analoids.

Background technique

Hemoglobin (Hemoglobin, Hb) is the main ingredient of red blood cell, is had in conjunction with being in invertibity with oxygen molecule Function is the main carriers of transport and the exchange of oxygen in human body.The pathophysiological change of many diseases is directed to Hb matter or amount Change.Its function is to combine oxygen in lung, is sent to whole body and respectively organizes and the carbon dioxide in tissue is sent to lung and is breathed out In vitro.Accurate detection hemoglobin parameters have the diagnosing and treating of anaemia and other disease of hematopoietic system important meaning Justice is also highly important for understanding blood donor whether there is or not anaemia, medical examiner's physical condition.

There are many kinds of the detection methods of hemoglobin, and the clinical labororatories such as hospital, inspection and quarantine mechanism mostly use haemocyte Analyzer, but equipment is not portable, be unfavorable for quickly detecting and bedside diagnoses (POCT), detects speed relative to Dry chemistry Slowly.It is wider in the examples of hemoglobin detection system application of the medical fields such as base, scene and emergency treatment, miniature portable.

But the examples of hemoglobin detection system of the prior art is in use, needs blood sample to be directly added dropwise or used capillary It is added dropwise on reaction film again after absorption, in fact it could happen that operator makes mistakes and leads to hemoglobin sample complicated for operation and being added Amount inaccuracy, to influence to detect quality, detection effect accuracy and repeatability are deteriorated.

Utility model content

In view of this, the utility model provides a kind of analoids, increase siphon sampling structure, cooperates with mating analyzer It uses, to solve the technical issues of proposing in background technique.

Siphon sampling structure generally uses in electric pole type detection system, but realization is had no in optical reflection type system With a kind of innovation structure used, solves sample by design folding line and siphon channel and suck distance and optical texture volume Conflicting contradiction bigger than normal will be only capable of the siphon sample introduction being just able to achieve in electric pole type POCT detection system originally, anti-in optics It penetrates on formula instrument and realizes.

The utility model solves above-mentioned technical problem by following technological means:

A kind of analoids, including substrate, one end of the substrate offer locating slot, positioning are also provided on the substrate Hole and instrument connection are pasted with reaction film on the substrate above instrument connection, syphon structure, institute are pasted on the reaction film It states syphon structure to be made of supporting layer and hydrophilic film, the hydrophilic film is pasted on pad level, and the supporting layer is pasted onto reaction On film.

Further, the supporting layer is made of double-sided adhesive, and the channel for entering blood is offered on the supporting layer. In order to make siphon sample volume meet test needs, the thickness of supporting layer is within the scope of 0.05~0.35mm, and more preferably thickness exists In the range of 0.1~0.2mm.

Further, the hydrophilic film is made of water wetted material, and the hydrophilic film offers auxiliary above the open end of channel Mouth of sucking blood is helped, the hydrophilic film offers exhaust outlet above the tail end of channel, and the diameter of gas vent is in 0.1~5mm range Interior, for more preferably diameter in the range of 0.5~4mm, optimal diameter range is in 0.8~3.4mm.

Blood sample mobility is fast on water wetted material, and blood sample to be measured can quickly fill with reaction chamber；Exhaust outlet is for arranging Air in reaction chamber out is conducive to blood sample sucking；Auxiliary suck blood mouth be conducive to blood sample import channel in.

Further, the auxiliary sucks blood mouth as semicircle or half elliptic.Semicircle or half elliptic is conducive to increase auxiliary The area for helping mouth of sucking blood is more advantageous to blood sample sucking, and outer openings size is in the range of 0.1~10mm, more preferably ruler It is very little in the range of 0.5~5mm, optimal size range is in 2.5~3.8mm.

Further, adhesion has layers of two-sided between the reaction film and substrate.

Further, partial disconnection is offered on the substrate, the partial disconnection is located on the outside of reaction film, and the partial disconnection is close Hydrophilic film is equipped with the side for the mouth that assists sucking blood.Partial disconnection facilitates substrate bending, shortens siphon path, and siphon is avoided to import road Electrical path length influences the repeatability and accuracy of analoids, rapidly enters blood sample in channel, detects in time.

Further, through-hole is offered in location hole corresponding position in the supporting layer and hydrophilic film.

Further, the substrate is printed on dark coating in reaction film bottom corresponding position.

Further, the dark coating is that the printing of ink material is made.The dark unglazed reflection of coating, prevents the light of analyzer The detection light for learning detector is irradiated on substrate, causes the result of mistake.

The utility model has the beneficial effects that

(1) the utility model combines syphon structure and reaction film on the basis of conventional examples of hemoglobin detection system Coming, blood sample is full of after channel, and syphon structure stopping continues to suck blood sample, and keep the sample volume of blood sample constant, The situation for avoiding operator's fault and causing the hemoglobin being added inaccurate occurs；Also, sample introduction when in order to improve test Convenience reduces sample volume, and increasing before partial disconnection makes substrate suck sample can bend, and shortens siphon path, makes blood sample This is quickly sucked in channel, is avoided the too long repeatability and accuracy for influencing analoids of siphon lead-in path, is kept detection more quasi- Really, fast.

(2) this analoids accurate positioning has locating slot on substrate, positions at location hole two, both can guarantee that analoids were accurate Movement when being inserted into analyzer, and can prevent analoids half are disconnected to bend, it is ensured that detection quality reduces personnel in test process and operates The error and uncertainty that may cause, improve the experience of user.

(3) this reagent chip architecture can be used for hemoglobin, blood glucose, uric acid, cholesterol, high density cholesterol, low-density gallbladder Sterol, triglycerides, transaminase etc. are using in the various tests of whole blood sample, since substrate is bent, the analoids tested It can be taken out easily from instrument by the bending end of substrate, avoid sample contamination instrument and operator, it is special that instrument does not have to setting Move back a structure, the cost of reduced test equipment.
