Abstract
The invention relates to an oncomelania-killing and cercaria-escaping experimental cup, and belongs to the technical field of the prevention and control of schistosomiasis. The oncomelania-killing and cercaria-escaping experimental cup consists of a sieve screen, a stainless steel annular support, bulges inside a cylindrical glass container, the cylindrical glass container and scale marks. By the device, the efficiency of an oncomelania-killing experiment of medicines can be improved, and the stability of the experiment is improved; and the experimental cup also can be used for the infectious oncomelania cercaria escaping experiment, the risk that staff is infected in the process for preparing cercariae is reduced, and the escaping number of the cercariae is increased.
Description
Technical field
A kind of spiral shell, ease larva of a tapeworm or the cercaria of a schistosome experiment cup of killing belongs to the prevention and cure of snail fever technical field.
Background technology
Oncomelania is the unique intermediate host of Schistosoma japonicum, and the control oncomelania is the effective means of control schistosomiasis propagation.Adopt the laboratory to soak method extremely to oncomelania drug screening at present, concrete grammar is to put into oncomelania with the 100mL beaker, and the loam cake gauze is put into soup.But this method, oncomelania climb out of beaker from the slit between gauze and the beaker sometimes, also have oncomelania to climb out of soup, rest on the space between gauze and the soup surface, and this causes oncomelania to fail and the soup excellent contact, and make experimental result unstable.In the preparation process of cercaria, exist oncomelania to climb out of the situation of beaker from gauze too, this might cause the experimenter to infect blood fluke, influences cercaria effusion quantity.This device can prevent climbing out of of oncomelania, makes oncomelania and soup excellent contact, improves experiment stability and conventional efficient; Can be reduced in the infected risk of staff in the preparation cercaria process, and improve cercaria effusion quantity.
Summary of the invention
The purpose of this invention is to provide a kind of spiral shell, ease larva of a tapeworm or the cercaria of a schistosome experiment cup of killing, this device can improve the efficient that medicine kills the spiral shell experiment, increases the stability of experiment, also can be used for the experiment of overflowing of infectious oncomelania cercaria.
Technical scheme of the present invention: a kind of spiral shell, ease larva of a tapeworm or the cercaria of a schistosome experiment cup of killing; Form by screen cloth 1, stainless steel ring shape support 2 and cylindrical glass container 4; Have screen cloth 1 on the stainless steel ring shape support 2; Have on cylindrical glass container 4 madial walls more than 3 or 3 inner projection 3 and on the same horizontal circumference of the following 1.5cm of 100mL graduation mark, graduation mark 5 is arranged on cylindrical glass container 4 lateral walls, is masked as 50,75 and 100mL respectively;
Oncomelania is put into cylindrical glass container 4; The stainless steel ring shape support 2 that will have screen cloth 1 places cylindrical glass container 4 upper ends; Stainless steel ring shape support 2 natural downslides are to cylindrical glass container inner projection 3 places; In cylindrical glass container 4, add dechlorination water or soup, after waiting to test completion, discard dechlorination water or soup.
Said screen cloth 1 can prevent that oncomelania from climbing out of from cylindrical glass container 4, improves experiment stability.
Said stainless steel ring shape support 2 materials are stainless steel, prevent to get rusty and have certain weight, and its outer rim distance circle cylindrical glass container 4 inwalls distance is less than 0.3cm,, can prevent that oncomelania from climbing out of from cylindrical glass container 4.
Said cylindrical glass container inner projection 3 quantity are equal to or greater than 3, and on same horizontal circumference, highly are lower than 100mL graduation mark 1.5cm, guarantee that oncomelania contacts with soup or dechlorination water in the experiment.
Said graduation mark 5 be 50,75 and 100mL be positioned at cylindrical glass container 4 sidewalls, convenient control soup or dechlorination water volume.
Beneficial effect of the present invention: this device can prevent climbing out of of oncomelania, makes oncomelania and soup excellent contact, improves experiment stability and conventional efficient; Can be reduced in the infected risk of staff in the preparation cercaria process.
