Description
Technical field
The utility model relates to that a kind of worm egg is collected and the direct medical appliance of hatching, refers to a kind of appliance that is used for blood fluke patient, ill domestic animal especially, and can directly detect the inversion type collection ovum that parasite exists by shirtsleeve operation and directly incubate device.
Background technology
At present, parasitic disease especially Schistosoma japonicum is a kind of serious infecting both domestic animals and human parasitic disease, its etiological diagnosis mainly relies on ight soil miracidium hatching method, ight soil miracidium hatching method is still current the most frequently used detection method as the correct diagnosis of snail fever, the detection method of regulation when also to be that country's examination is up to standard check and accept.Though this each province, method epidemic-stricken area is slightly different, total running program basically identical, this method will be through three road steps: (1) is that the copper sieve filters, and leaches thing and eluriates with the nylon bolting silk; (2) add sediment bowl, precipitation is changed water, removes supernatant; (3) pour in Erlenmeyer flask, the kieldahl flask and hatch, for ease of observing miracidium, also will be under bottleneck 1/2 place add the absorbent cotton of a 2-3cm, add clear water again to bottleneck.This method is commonly referred to conventional nylon bolting silk and eluriates ight soil miracidium hatching method, because this method had both been passed through the copper screen filtration, eluriate through the nylon bolting silk again, the excrement slag is clear, hatching miracidium is easy to observe, but owing to will pass through the copper screen filtration, multisteps such as nylon bolting silk elutriation are rapid, each step some worm's ovums that all will scatter and disappear.So test according to 16 parts of positive ight soil of the Wuxi prevention and cure of schistosomiasis, detect several 1998 of miracidium altogether, be 1171 in the precipitation wherein, only account for 58.6%, and go residual assortedly hatch 827 of miracidiums, account for 38.1% of sum, other change, and water etc. is lost to account for 3.3%.In addition, because operation steps is many, length consuming time.For this reason, be necessary sensitiveer, the method efficiently of development.Another kind of directly stool for hatching method is: (1) repeated precipitation in sediment bowl is changed water; (2) pour in Erlenmeyer flask, the kieldahl flask absorbent cotton that 1/2 place under (3) bottleneck adds a 2-3cm into, add clear water again to bottleneck.Because ight soil filters without copper sieving cup, not eluriate again through the nylon bolting silk, the excrement slag is many, and pigment is dense, influences miracidium and hatches and follow-up observation.Shen Jie 50 test findings in Shanghai show that hatching the miracidium number under the available light is 7355, and only hatches 1990 of miracidiums under the dark situations, differs to reach 3 times more than.Summary is got up, and the shortcoming of the method for these two kinds of hatchings all is: (1) is low to the susceptibility of low infectiosity crowd or animal; (2) worm's ovum is lost manyly, counts inaccurate; (3) step is many, length consuming time.
Summary of the invention
In order to overcome above-mentioned weak point, fundamental purpose of the present utility model aims to provide a kind of device of finishing the filtration and the hatching of determinand in a container, realizes a kind of susceptibility height, count enable, expense is low, and is easy to operate, is applicable to that the inversion type collection ovum of on-the-spot use is directly incubated device.
The technical problems to be solved in the utility model is: solve this hatching utensil and how reduce step through the copper screen filtration, how help miracidium observation problem; Solve this hatching utensil and how to reduce the conversion of determinand in different vessels, reduce operation steps problems such as adding tampon; Solving to filter influences the residual assorted of hatching effect and observation effect, and can easily realize sieving and finish in a container and can promote relevant technologies problem such as hatching by concussion with hatching.
The technical scheme that its technical matters that solves the utility model adopts is: this device is made up of infundibulate lower cover, hatching cup and circular upper cover, after three parts of this separation closely cooperate mutually successively, be combined as holistic utensil in conjunction with enclosed construction, the infundibulate lower cover closely mates sealing by hasp A with the hatching cup and is connected, circular upper cover closely mates sealing by hasp B with the hatching cup and is connected, wherein:
The top center position of one infundibulate lower cover is provided with the opening observation tube, the bottom is provided with and hatches the hasp A that cup is combined closely, observation tube and hasp A respectively with the infundibulate lower cover body structure that permeates, the inside of infundibulate lower cover is provided with and the groove A of hatching glass end opening tight connecting, be provided with size shape and the consistent elastic cushion of hatching cup rim of a cup in the groove A, is connected for tight coupling sealing between elastic cushion and the rim of a cup, the bottom of sealing hatching glass is combined as the cup body structure of lower seal;
One circular upper cover is provided with and hatches the hasp B that cup is combined closely, hasp B and the circular upper cover body structure that permeates, the inside of circular upper cover is provided with and the groove B of hatching cup tight connecting suitable for reading, be provided with size shape and the consistent elastic cushion of hatching cup in the groove B, the top of cup is hatched in sealing, is combined as the cup body structure of top seal;
What the top of one hatching cup was provided with convex goes up a cup edge, and the bottom is provided with the following glass edge of convex, last cup edge and following glass of edge respectively with the cup of the hatching glass body structure that permeates; Mutually by being pressed into fastening after the wringing fit, hatch the bottom of cup in conjunction with sealing between the hasp A of following cup edge and infundibulate lower cover; Mutually by being pressed into fastening after the wringing fit, hatch a cup top between the hasp B of last cup edge and circular upper cover in conjunction with sealing; The inner card of hatching cup has the fine sand net, is by the colloid fixed connection between fine sand net and the hatching cup.
Hasp A and hasp B that described inversion type collection ovum is directly incubated device respectively are distributed as 4 hasps along the even position of circumference respectively.
