Abstract
The filter sink device that the utility model is related to be used when a kind of parasite detects, including filter cup, outstanding heavy cup, upper layer waste liquid waste cock, sediment bowl, different filter cups can be replaced as needed, also the outstanding heavy cup of different scale sizes can be designed according to digestive juice volume, outstanding heavy cup bottom is equipped with switch, upper layer filtrate can be discharged, parasite then stays in sediment bowl bottom.The utility model can improve the recall rate of parasite detection and shorten detection time, and design simply, practical and convenient.
Description
Technical field
The present invention relates to parasite detection fields, and in particular to the filter sink device used when a kind of parasite detection.
Background technology
It is first when parasite (such as jaw mouth nematode, Anisakid nematode, trichina) to parasitizing muscle or internal organ is detected
It first needs to be digested muscle or internal organ with digestive juice, is then filtered postdigestive suspension and washing of precipitate, then will
Bottom suspension after precipitation is placed in microscopically observation, finds out polypide.Existing mode of operation is to be placed in postdigestive suspension
It is washed repeatedly after conical graduate precipitation, when the waste liquid on upper layer is toppled in washing, section parasitic worm can be also poured, be substantially reduced
Parasite recall rate, and the postdigestive remainder fine slag of sample tissue also can be difficult to bottom with parasite coprecipitation
It cleans, causes the visual field in further microscope detects to obscure, increase detection difficulty and detection time.
Invention content
The present invention is directed to the deficiency of aforesaid operations mode, provides the filter used when a kind of novel detection parasite and sinks
Device.
It includes with lower structure that the present invention, which filters sink device,：
(1) filter cup can be equipped with the different filterings such as 10 mesh, 20 mesh, 30 mesh according to the size of filter cup bottom screen
Cup；
(2) heavy cup is hanged, can connect and coordinate from different filter cups；Being marked on outstanding heavy cup has；
(3) upper layer waste liquid waste cock is located at outstanding heavy cup bottom side.After tissue digestion liquid filtering precipitation, parasite is heavy
It forms sediment in bottom, after waste liquid floats, opens upper layer waste liquid waste cock, filtering sink device waste liquid more than switch can be discharged,
And parasite to be detected is then deposited in bottom of a cup.
(4) sediment bowl can coordinate with outstanding heavy cup and fix, and be used for the washing of precipitate of tissue digestion liquid, posting after washes clean
It is infested to sink to sediment bowl bottom, first waste liquid is discharged, then sediment bowl and outstanding heavy cup are separated, then takes the suspension in sediment bowl
To under stereomicroscope, parasite detection is carried out.
A kind of filter sink device used when parasite detection, including it is filter cup, outstanding heavy cup, upper layer waste liquid waste cock, heavy
Shallow lake cup, is filter cup, outstanding heavy cup and sediment bowl successively from top to bottom, and three is connected with each other cooperation, connection type be threadedly coupled,
Clamping or other connection types.Waste liquid waste cock is located at outstanding heavy cup bottom side at the middle and upper levels for it.Filter cup is according to bottom screen
Difference, be equipped with the different filter cup such as 10 mesh, 20 mesh, 30 mesh.Outstanding heavy cup can be connected from different filter cups to be coordinated, and heavy cup is hanged
Upper label has.
When filter cup, outstanding connection type between heavy cup and sediment bowl are to be threadedly coupled, hang heavy cup rim of a cup and is equipped with screw thread,
Sediment bowl is equipped with spiral interface.
Using the present invention filter sink device when, first according to detection Object Selection appropriate size filter cup, by filter cup,
It hangs heavy cup and sediment bowl is sequentially connected after fixing, tissue digestion liquid is poured into filter cup, after the filtering of the bottom screen of filter cup,
A part of filter residue is left on strainer, and filtrate then flows in outstanding heavy cup and sediment bowl.By the precipitation of certain time, polypide and small
Part filter residue sinks to sediment bowl bottom of a cup, and most of filter residue floats, and opens the upper layer waste liquid waste cock for hanging heavy cup bottom at this time,
Waste liquid more than switch calibration can be discharged filter sink device, and the polypide of bottom still stays in sediment bowl.It is then shut off switch, then
Brine bottom precipitation is poured into, the filter residue of bottom can float since concentration is different, and polypide is then deposited in sediment bowl
Bottom, then discharge part filter residue is turned on the switch, it washs 3~4 times repeatedly, until bottom precipitation becomes clarification, so that it may will precipitate
Cup is separated with outstanding heavy cup, is taken progress parasite under stereomicroscope and is had detected.
The beneficial effects of the invention are as follows：The different cup body of combined connection, two are closed by the filtering of tissue digestion liquid and precipitation
It is one, improves the treatment effeciency of the tissue digestion liquid detected for parasite.When washing the precipitations such as polypide, waste liquid is improved
Expulsion efficiency, while the detraction of polypide in washing process is decreased, recall rate is improved, ensure that the reliable of detection result
Property.

Fig. 1 is the whole side view of the present invention；
Fig. 2 is filter cup schematic diagram；
Fig. 3 is outstanding heavy cup schematic diagram；
Fig. 4 is the schematic diagram of upper layer waste liquid waste cock；
Fig. 5 is sediment bowl schematic diagram.
Specific implementation mode：
As shown in Figs. 1-5, the filter sink device used when a kind of parasite detection, including filter cup 1, outstanding heavy cup 2, upper layer
Waste liquid waste cock 3, sediment bowl 4 are filter cup 1, outstanding heavy cup 2 and sediment bowl 4 successively from top to bottom, and three, which is connected with each other, to be matched
It closes, connection type is threaded connection, clamping or other connection types.Waste liquid waste cock is located at outstanding heavy cup bottom one at the middle and upper levels for it
Side.Filter cup 1 is equipped with the different filter cups such as 10 mesh, 20 mesh, 30 mesh according to the difference of bottom screen.Outstanding heavy cup 2 can be with difference
Filter cup connection cooperation, marking on outstanding heavy cup 2 has.
When filter cup 1, outstanding connection type between heavy cup 2 and sediment bowl 4 are to be threadedly coupled, outstanding 2 rim of a cup of heavy cup is equipped with
Screw thread, sediment bowl 4 are equipped with spiral interface.
When the filter sink device of the present invention is used for the detection of jaw mouth nematode, the postdigestive tissue suspension of 500mL volumes is taken, is taken
It is suitble to the filter cup 1 of 10 mesh screens of detection jaw mouth nematode, is tightened on 2 rim of a cup of outstanding heavy cup, suspension is after filter cup filters, greatly
It is left on strainer in the filter residue of 10 mesh sizes, filtrate then flows in cup.By the precipitation of certain time, polypide and fraction filter
Slag sinks to 4 bottom of a cup of sediment bowl, and most of filter residue floats, and opens upper layer waste liquid waste cock 3, waste liquid meeting more than switch calibration
It is discharged outstanding heavy cup 2, and the polypide of bottom still stays in sediment bowl 4.It is then shut off switch, then pours into brine bottom
The filter residue of precipitation, bottom can float since concentration is different, and polypide is then deposited in sediment bowl bottom, then turn on the switch discharge part
Filter residue washs 3~4 times repeatedly, until bottom precipitation becomes clarification, so that it may to unscrew sediment bowl and outstanding heavy cup, take body
Jaw mouth nematode is carried out under stereomicroscope to have detected.
