Description
Technical field
The utility model is related to medical diagnosis class equipment technology field more particularly to a kind of liquid sample detection devices.
Background technology
The abuse problem of drug or drugs has become the social concern of getting worse, U.S. Department of Health and Human Services's door
The investigation of 2003 finds that the ratio of drug abuse is up to 8.2% in the American of 12 years old or more.With the hair of economic society
Exhibition, the ratio of drug abuse gradually increase, and the medicament categories abused are also more and more.
Liquid sample generally is collected using detection box to the quick detection of the Drug Abuses such as drugs, then by related skill
The part submergence that art personnel are inserted into detection strip and make detection strip in the sample, takes out strip and reads inspection after a certain period of time
Survey result.However, in order to drugs operation and monitoring drug-taking problem, this test has become a standard many when
Program, for example, employ, go to school, sport, law enforcement etc., operated by amateur testing staff.It is therefore desirable to provide a kind of detection dress
It puts, operating personnel is avoided to touch the sample in open liquid collection and detection device, jeopardize the health of operating personnel.Meanwhile
Also want to the collection and detection device can stored samples, with facilitate in the case where there is objection to testing result sample recheck.
Moreover, because the test of drug abuse has become a standardization program, it is also desirable to which the price of detection device is sufficiently minimized, Neng Gouman
The demand of sufficient large-scale use.
Further, since smoker has the motivation for concealing drug abuse or Drug Abuse, there is sample adulteration；
Meanwhile the substantially type of drug used in person to be detected can not be accurately estimated before detection, accordingly, it would be desirable to utilize an inspection
It surveys device and detects the drug that the possibility of sample adulteration situation and multiple types as possible is sucked simultaneously in one-time detection.
In some existing detection devices, there is the lid that the test strips by multiple detection different pharmaceuticals are placed on detection device
On, inverted device detects to realize after closeing the lid after collecting fluid sample.But the space of lid is limited, the examination that can be accommodated
Paper slip quantity is also few, and therefore, the drug that can be detected simultaneously in same sample is relatively fewer.Also, this detection device needs
Will in cover integration testing element and sealer sealing, it is complex in manufacturing process, it is of high cost.Meanwhile these devices
It is operationally also complex, it is difficult to accurate judgement detection initial time, the inconvenient accurate interpretation detection of lay operators
Initial time.
Existing urine detector can not accurately decision maker whether sealed, it is impossible to prompting detection the time started,
Meanwhile test strips slot limited amount, it is difficult to while meet urine detection of adulterations and a variety of drug metabolite composition detections.
Invention content
The utility model cannot prompt detection time started, test strips slot a limited number of for of the existing technology
Shortcoming, and provide a kind of liquid sample detection device that can be prompted the detection time started, a plurality of paper slip slot is provided.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
A kind of liquid sample detection device, including cup body and cover, cup body includes sample chamber, and cup body is equipped at the top of sample chamber
