Abstract
The present invention relates to the filter sink devices used when a kind of detection of helminth, including filter cup, outstanding heavy cup, upper layer waste liquid waste cock, sediment bowl, different filter cups can be replaced as needed, the outstanding heavy cup of different scale sizes can also be designed according to digestive juice volume, outstanding heavy cup bottom is equipped with switch, upper layer filtrate can be discharged, helminth then stays in sediment bowl bottom.The present invention can improve the recall rate of helminth detection and shorten detection time, and design simply, practical and convenient.
Description
Technical field: the present invention relates to helminth detection fields, and in particular to the filter that a kind of helminth uses when detecting is heavy
Device.
Technical background: the helminth (such as jaw mouth nematode, Anisakid nematode, trichina) for parasitizing muscle or internal organ is carried out
When detection, it is necessary first to digest muscle or internal organ with digestive juice, then postdigestive suspension is filtered and is precipitated
Washing, then the bottom suspension after precipitating is placed in microscopically observation, find out polypide.Existing mode of operation is will be postdigestive
Suspension washs repeatedly after being placed in conical graduate precipitating, when the waste liquid on upper layer is toppled in washing, section parasitic worm can be also poured,
Helminth recall rate is greatly reduced, and the postdigestive remainder fine slag of sample tissue can also be arrived with helminth coprecipitation
Bottom is difficult to clean, and causes the visual field in the detection of further microscope to obscure, increases detection difficulty and detection time.
Summary of the invention:
The present invention is directed to the deficiency of aforesaid operations mode, and the filter used when providing a kind of novel detection helminth is heavy to be filled
It sets.
It includes with flowering structure that the present invention, which filters sink device:
(1) filter cup, can be according to the size of filter cup bottom screen, equipped with different filterings such as 10 mesh, 20 mesh, 30 mesh
Cup；
(2) heavy cup is hanged, can connect and cooperate from different filter cups；Marking 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 precipitating, helminth 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 helminth to be detected is then deposited in bottom of a cup.
(4) sediment bowl can cooperate with outstanding heavy cup and fix, 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, helminth detection is carried out.
The filter sink device that uses when a kind of detection helminth, including it is filter cup, outstanding heavy cup, upper layer waste liquid waste cock, heavy
Shallow lake cup, is successively filter cup, outstanding heavy cup and sediment bowl 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, equipped with different filter cups such as 10 mesh, 20 mesh, 30 mesh.Outstanding heavy cup can be connected from different filter cups to be cooperated, and heavy cup is hanged
Upper label has.
When the connection type between filter cup, outstanding heavy cup and sediment bowl is to be threadedly coupled, hangs heavy cup rim of a cup and is equipped with screw thread,
Sediment bowl is equipped with spiral interface.
When using filter sink device of the invention, first according to test object select 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 precipitating 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 of outstanding 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 helminth under stereomicroscope and is had detected.
The beneficial effects of the present invention are: the cup body that combined connection is different, closes two for the filtering of tissue digestion liquid and precipitating
It is one, improves the treatment effeciency of the tissue digestion liquid for helminth detection.When washing the precipitating 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 effect
Property.
Detailed description of the invention:
Fig. 1 is whole side view of the 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 embodiment:
As shown in Figs. 1-5, the filter sink device that uses when a kind of detection helminth, including filter cup 1, outstanding heavy cup 2, upper layer are useless
Liquid waste cock 3, sediment bowl 4 are successively that filter cup 1, outstanding heavy cup 2 and sediment bowl 4, three are connected with each other cooperation from top to bottom,
Connection type is threaded connection, 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 1 is according to the difference of bottom screen, equipped with different filter cups such as 10 mesh, 20 mesh, 30 mesh.Outstanding heavy cup 2 can from it is different
Filter cup connection cooperation, hanging to mark on heavy cup 2 has.
When the connection type between filter cup 1, outstanding heavy cup 2 and sediment bowl 4 is 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 filter sink device of the invention is used for the detection of jaw mouth nematode, the postdigestive tissue suspension of 500mL volume is taken, is taken
It is suitble to the filter cup 1 of 10 mesh screens of detection jaw mouth nematode, is tightened on outstanding 2 rim of a cup of 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 precipitating 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 more than switch calibration
It can be 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 portion's precipitating, bottom can float since concentration is different, and polypide is then deposited in sediment bowl bottom, then turns on the switch discharge unit
Divide filter residue, wash 3~4 times repeatedly, until bottom precipitation becomes clarification, so that it may unscrew sediment bowl and outstanding heavy cup, take
Jaw mouth nematode is carried out under stereomicroscope to have detected.
