A kind of syringe type stool sampling device
Technical field
The present invention relates to medical apparatus technical field, more specifically, relate to a kind of syringe type stool sampling device.
Background technology
At present, common ight soil detection normally adopts gatherer from the ight soil of patient, collect sub-fraction sample and detects.Some organic molecule (such as DNA composition and haemoglobin) in ight soil can as the mark of some enterogastric diseases, organic molecule in human faecal mass is quantitatively detected, some pathological phenomenons of intestines and stomach can be understood, indirectly judge GI function and disease event, thus predict, monitor generation, the development of some enterogastric diseases.Therefore, ight soil detects has become the conventional project that disease detects in a lot of medical institutions.
In existing ight soil testing process; be generally first by patient by collecting dung in a stool sampling device; stool sampling device generally deposits special protection liquid; under the protection of protection liquid; just can prevent the mark in ight soil from producing degraded; to ensure the integrality of fecal sample, thus be conducive to the accuracy of detection.Meanwhile, after the ight soil in sampler is shaken up, generally will take out a certain amount of ight soil solution with pipettor from sampler, by detecting instrument, fecal sample quantitatively be detected.But the sampling groove of prior art sampler is generally spade, this design gets collection fecal sample for the ease of shovel in ight soil.
But the sampling groove of above-mentioned spade allows user be difficult to hold the collection capacity of fecal sample, thus easily impacts final assay; Further, concentrate due to ight soil and be deposited in spade sampling groove, make fecal sample be difficult to dissolve in fast in the protection liquid of sampler, this situation also can affect to assay.
Utility model content
The present invention is for overcoming at least one defect described in above-mentioned prior art; a kind of syringe type stool sampling device is provided; its structure is simple; easy to use; not only can be conducive to user and effectively hold sampling amount in the process of stool sampling; and fecal sample can be convenient to dissolve in protection liquid fast, thus make assay more accurate.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of syringe type stool sampling device, wherein, comprise sampler, described sampler comprises hollow socket and push rod, push rod one end is placed in hollow socket, and described push rod can produce the relative displacement of certain distance in hollow socket.
In the present invention, also comprise gatherer matching used with described sampler, described gatherer is provided with lid, and gatherer and lid are tightly connected by screw thread rotation is dismountable, are loaded with protection liquid in gatherer.Described gatherer is centrifuge tube or centrifugal bottle that can be vertical, and the volume scope of preferred gatherer is 20-250ml.
Sampler in technical solution of the present invention comprises two kinds of forms:
Form one is, described hollow socket is transparent plastic drum, hollow socket one end outer wall is provided with convex edge, the other end from port, outer wall marks within the scope of certain distance scale, the height of fecal specimens in hollow socket is read when conveniently getting just, the position of the top certain distance of scale is provided with the through hole of a certain size and quantity, and the shape of through hole is not limit, to remove air resistance when getting just in socket.
One end that described push rod is placed in hollow socket is provided with piston, and one end that piston is provided with convex edge from hollow tube cylinder enters hollow socket, and closely cooperates with hollow tube walls.
Further, after taking fecal specimens, described hollow socket estable is placed in gatherer, and the upper end of push rod coincide with the lid of gatherer and is connected.
The using method of this kind of form is that user is after an action of the bowels drained, turns on the lid of gatherer, a hand-held gatherer, takes sampler on the other hand; Being moved to by the push rod of sampler has above through hole, exposes sampling cavity, selects ight soil to have certain thickness place, vertically inserts ight soil, get just, then sampler is inserted gatherer after rotating a circle; Fix hollow socket with hand, promote push rod and fecal specimens is injected in gatherer, lid and gatherer are screwed, and mixing of rolling; The label of pipe outer wall finished writing name and adopts the just date, returning tester, so far end of operation.
Form two is, described hollow socket is transparent plastic drum, hollow socket one end outer wall is provided with convex edge, on other end outer wall, from port, within the scope of certain distance, mark has scale, the height of fecal specimens in hollow socket is read when conveniently getting just, the position of the top certain distance of scale is provided with the through hole of a certain size and quantity, and the shape of through hole is not limit, to remove air resistance when getting just in socket.
Further, on the outer wall that described hollow socket is provided with one end, convex edge, cover has adapter, and adapter is positioned at below convex edge.Described adapter comprises cylindrical main body and is located at the cylindrical boss of main body one end, the external diameter of cylindrical boss and the internal diameter of gatherer bottleneck suitable, so that after taking ight soil by sampler, the hollow socket of sampler is fixed on gatherer bottle mouth position, avoids rocking.Adapter is provided with different size, to adapt to the gatherer of not co-content specification.Described adapter center is provided with the large through-hole matched with hollow socket external diameter, to be enclosed within hollow tube drum outer wall by adapter.Also by integrated mould, adapter and hollow socket can be prepared into integral type socket.The making material of described adapter can be silica gel, also can be plastics, can also be rubber.
One end that described push rod is placed in hollow socket is provided with piston, and one end that piston is provided with convex edge from hollow tube cylinder enters hollow socket, and closely cooperates with hollow tube walls.
The using method of this kind of form is that user is after an action of the bowels drained, turns on the lid of gatherer, a hand-held gatherer twisted the lid off, and takes sampler on the other hand; Being moved to by the push rod of sampler has above through hole, exposes sampling cavity, selects ight soil to have certain thickness place, vertically inserts ight soil, get just, then sampler is inserted gatherer after rotating a circle; Utilize the adapter on hollow tube drum outer wall that hollow socket is fixed on gatherer bottle mouth position, fecal specimens is injected in gatherer by pressure push rod, then takes out emptying sampler and loses into dustbin, lid and gatherer are screwed, and mixing of rolling; The label of pipe outer wall finished writing name and adopts the just date, returning tester, so far end of operation.
The invention has the beneficial effects as follows:
Because hollow socket is transparent plastic drum and outer wall subscript is marked with scale; just amount of getting when getting just can be determined according to the height of fecal specimens in socket floorage and hollow socket; such as socket floorage is 1cm2; faecal density is 1g/cm3; the height then getting the fecal specimens needed for 1g, 2g, 4g ight soil is 1cm; 2cm, 4cm.So just to sampling amount accurate assurance, the accurate calculating in checkout procedure can be convenient to.
To be connected with push rod due to hollow socket and the relative displacement of certain distance can be produced, therefore after having gathered fecal specimens, push rod can be utilized to be released by the fecal sample in hollow socket, and then fully dissolve in the protection liquid of gatherer splendid attire.
Due to gatherer be can be vertical centrifuge tube or centrifugal bottle, take after fecal specimens dissolves in protection liquid, directly gatherer can be put into centrifuge, eliminate and shift the intermediate steps of sample, make operation simpler.
Therefore, structure of the present invention is simple, easy to use, not only can be conducive to user and effectively hold sampling amount in the process of stool sampling, and can be convenient to fecal sample and dissolve in protection liquid fast, thus makes assay more accurate.
