Abstract

The utility model relates to an assembled test tube used for cultivating fruit flies in the field of biological heredity and medical science, which is formed by that a main pipe with both open ends is connected and assembled with a tail pipe with an open upper part and a closed bottom end. The utility model is characterized in that two assembled test tubes are in a group. For each test tube in the group, the main pipe is connected with the tail tube in the plug-in type and movable fit, and the main pipes of the two test tubes in the group can also form a movable fit. The utility model realizes that the fruit flies are transferred to a new culture medium without scurry under the condition of no need of anaesthesia, effectively lowers operating difficulty, reduces experiment errors and raises test accuracy.

Description

The assembled test tube

The utility model relates to a kind of test tube that is used for health or field of biology.

When utilizing fruit bat to carry out biogenetics research and the evaluation test of health food function assessment, the fruit bat of being adopted is cultivated utensil and mostly is common test tube or the erlenmeyer flask that the physical and chemical experiment chamber is used, when changing culture medium, need fruit bat from disposable another test tube that is transferred to of test tube at every turn, disperse for fear of fruit bat in transfer process, need operating personnel's technology quite skilled, sometimes even need many people to carry out jointly.Also there is the anesthesia used to shift, but the physiological function of fruit bat is always had some influences.Chinese patent 93218024 discloses a kind of fabricated test tube, and it has the base of cavity and no end test tube by being threaded, and loading and unloading still make things convenient for inadequately, also are not suitable for the cultivation of fruit bat.

The purpose of this utility model is to provide the assembled test tube that can change culture medium fast between a kind of fruit bat culture period under the situation of not anaesthetizing and be unlikely to make fruit bat to be dispersed.

In order to realize above-mentioned goal of the invention, the technical solution adopted in the utility model is: the tail pipe that this assembled test tube is sealed by the person in charge and the upper opening bottom of both ends open is linked and packed in the open end of being responsible for terminal and tail pipe and forms, and two in this assembled test tube is one group, the person in charge of each test tube and the connected mode of tail pipe be plug-in type movingly, and organize end that interior two test tubes are responsible for also can plug-in type movingly.The mode that is connected can be the mutual socket of tube wall, also can be to connect by a sleeve pipe.On described person in charge's tube wall, have the side mouth.

After adopting design as above, because test tube two parts insertable is connected, and also can plug-in type between the person in charge of two test tubes in the group movingly, thereby be responsible in can the realization group and tail pipe between quick loading and unloading, in raising the fruit bat process, under situation about needn't anaesthetize, finish fruit bat to the transfer of dispersing of the nothing of new culture medium, effectively reduce operation easier, reduce test error, improve the test degree of accuracy.

Be described further below in conjunction with the structure and the use of drawings and Examples this assembled test tube.

Fig. 1 is the profile of a test tube among a kind of embodiment of the utility model assembled test tube.

Fig. 2 is the profile of a test tube among another embodiment of the utility model assembled test tube.

As Fig. 1, being responsible for 1 is connected with tail pipe 2 usefulness one built-in sleeve pipe 3, sleeve pipe 3 and end 4 tight fits of being responsible for 1, with the top 6 of tail pipe 2 movingly, the test tube basically identical that the shape structure of another test tube and specification and Fig. 1 provide in the group, different is its sleeve pipe 3 be responsible for 1 end 4 movingly, and with openend 6 tight fits of tail pipe 2.Fruit bat in will raising is when new media transfer, will not pour out from the test tube mouth by fruit bat, need not open the test tube mouth of wrapping, utilize the phototaxis of fruit bat fruit bat to be focused among the person in charge 1 earlier during operation, break away from tail pipe 2 with being about to be responsible for 1, and fill the person in charge 1 end 4 socket with it of another test tube of new culture medium in will organizing rapidly, after the inversion fruit bat is transferred to the person in charge 1 of another new test tube from the person in charge 1 who organizes an interior test tube, be responsible for two again and separate, at last in that the assembling of new test tube is complete, thereby finish whole transfer process.Can in time checkmate fruit bat from wherein going out clearly by being responsible for 1 tube wall side mouth 5.

Another modification of embodiment shown in Figure 1 is that sleeve pipe 3 is external.

Test tube of embodiment shown in Figure 2 and test tube shown in Fig. 1 different are not have sleeve pipe 3, the connected mode of each test tube person in charge 1 and tail pipe 2 is for being responsible for the mutual socket between 1 end 4 and tail pipe 2 openends 6 tube walls, and the identical and specification difference of two test tube shaped columnar structures in the group can guarantee that two test tubes are responsible for 1 also socket mutually of end 4.Its operation sequence is embodiment as shown in Figure 2.In the present embodiment being equipped with symmetrical projection on the tube wall near the openend 6 of being responsible for 1 end 4 and tail pipe 2, can limit the degree of depth of socket in addition, and can utilize its will be responsible for 1 and tail pipe 2 carry out " X " and bundle.

Claims

1, a kind of assembled test tube, locate to be linked and packed at the openend (6) of the end (4) of being responsible for (1) and tail pipe (2) by the tail pipe (2) of the person in charge (1) of both ends open and the sealing of upper opening bottom and form, it is characterized in that two in described assembled test tube is one group, the connected mode of the person in charge of two test tubes (1) and tail pipe (2) be plug-in type movingly, and organize between the person in charge's (1) the end (4) of interior two test tubes also can plug-in type movingly.

2, assembled test tube as claimed in claim 1 is characterized in that having side mouth (5) on the described person in charge (1) tube wall.

3, assembled test tube as claimed in claim 1 or 2 is characterized in that the described plug-in type end (4) and the mutual socket of tube wall of the openend (6) of tail pipe (2) and the mutual socket of end (4) tube wall of organizing the person in charge (1) of interior two test tubes for being responsible for (1) movingly.
