Abstract
The utility model relates to a constant-temperature water bath experiment device, comprising a constant-temperature water bath pipe, a water bath pump, a transducer and a computer, wherein the constant-temperature water bath pipe is of an interlayer structure; the water bath pump is communicated with an outer layer of the constant-temperature water bath pipe through a pipe; one end of the transducer is connected with a wire hook; the other end of the transducer is connected with the computer; an L-shaped hook is fixed above the constant-temperature water bath pipe through a cross bar; the lower end of the L-shaped hook is inserted into the middle part of inner nutrient solution of the constant-temperature water bath pipe; a dosing device is fixed on the hook rod part of the L-shaped hook through an iron hoop; and the dosing device is of a long neck funnel. By adopting the constant-temperature water bath experiment device, a lot of drugs with initial concentration can be directly added to achieve a target organ; the constant-temperature water bath experiment device is rapid to become effective, and sensitive; the initial concentration is not diluted; unstable water solution medicament is not affected by degradation of the nutrient solution in the bath pipe; the dosing operation is simple and convenient; an error does not easily appear; and the constant-temperature water bath experiment device can more accurately and more sensitively measure the minimal and the maximal reaction and corresponding concentration in a medicament quantitative test.
Description
Technical field
This use is novel to relate to a kind of experimental provision, relates to a kind of water bath with thermostatic control experimental provision specifically.
Background technology
In (as annulus trachealis, arterial ring, the ileum etc.) scientific research of most isolated organs or education experiment, the water bath with thermostatic control pipe equipment that is absolutely necessary, its adding method thereof is to get pharmaceutical with pipettor, is bathing unsettled dripping above the pipe.The shortcoming of this adding method thereof is: medicine needs diffusion to arrive isolated organ in nutrient solution, and onset is slower; And reduced obviously by dilution back concentration, reaction sensitivity reduces; Easily be degraded at the unsettled medicine of the aqueous solution in addition, and concentration is further descended, cause effect not good enough; Operation easily causes error because dripping on tube wall or the suspension line.
The utility model content
Slow in order to overcome the onset of using the pipettor dosing to cause in the existing water bath with thermostatic control experiment, sensitivity reduces, feeding operations inconvenience, problems such as error is big, the utility model provide a kind of water bath with thermostatic control experimental provision, the medicine organ surface that can go directly, rapid-action, highly sensitive, and keep original content not diluted, the unsettled medicine of the aqueous solution is not influenced by degraded yet.
To achieve these goals, the utility model is by the following technical solutions:
A kind of water bath with thermostatic control experimental provision, comprise water bath with thermostatic control pipe, water-bath pump, transducer and computer, described water bath with thermostatic control pipe is sandwich, described water-bath pump is communicated with by the skin of pipe and water bath with thermostatic control pipe, fixedly there is L type hook described water bath with thermostatic control pipe top by cross bar, middle part in the internal layer nutrient solution of the lower end insertion water bath with thermostatic control pipe of L type hook, an end of described transducer connects wired hook, and the other end of transducer is connected with computer.
The shank part of described L type hook fixedly has chemicals dosing plant by iron hoop, and described chemicals dosing plant is the long neck funnel shape.
Operation principle of the present utility model is: during practical operation, isolated organ (annulus trachealis, arterial ring, ileum etc.) is fixed on the hook of L type hook Yu Xian Hook, adjust the position of iron hoop, make the direct and stripped organ pipe in bottom of chemicals dosing plant close, the water-bath pump constantly circulates the water of water bath with thermostatic control outer tube layer the inside, keep temperature constant, by the chemicals dosing plant dosing, make medicine directly be added to the organ pipe surface of exsomatizing, transducer is measured the tension variation of the organ pipe smooth muscle that exsomatizes, and the tension variation signal transferred in the computer, carry out data analysis and handle.
The utility model has the advantages that: in the quality assurance of drug test, can directly add relatively large original content medicine and arrive target organ (in vitro tissue organ), rapid-action, sensitive, keep original content not diluted, the unsettled medicine of the aqueous solution can not be subjected to bathing the degraded influence of nutrient solution in the pipe yet, and feeding operations is simple and convenient, is not prone to error.In the medicine quantitative test, during particularly the gradient dose-effect reacts, can be more accurate, sensitiveer mensuration minimum, maximum reaction and corresponding concentration.
This device is to initiate both at home and abroad, and Chinese and foreign documents is not appeared in the newspapers.Can be widely used in the education experiments such as scientific experiments such as medical science, pharmacy, life science and preclinical medicine, clinical medicine, dentistry, nursing, pharmacy, public hygienics, life science.

The specific embodiment
As shown in the figure, a kind of water bath with thermostatic control experimental provision, comprise water bath with thermostatic control pipe 1, water-bath pump 2, transducer 3 and computer 4, described water bath with thermostatic control pipe 1 is sandwich, described water-bath pump 2 is communicated with by the skin of pipe and water bath with thermostatic control pipe 1, and an end of described transducer 3 connects wired hook 5, and the other end of described transducer 3 is connected with computer 4, water bath with thermostatic control pipe 1 top fixedly has the lower end of L type hook 9, L type hook 9 to insert in the water bath with thermostatic control pipe 1 by cross bar.
The shank part of described L type hook 9 fixedly has chemicals dosing plant 6 by iron hoop, and described chemicals dosing plant 6 is the long neck funnel shape.
During practical operation, isolated organ 7 is fixed on the hook of L type hook 9 and line hook 5, adjust the position of iron hoop, the bottom that makes chemicals dosing plant 6 directly and isolated organ 7 close, water-bath pump 2 constantly circulates the water of water bath with thermostatic control pipe 1 outer the inside, keep temperature constant, by chemicals dosing plant 6 dosings, make medicine directly be added to target organ 7 surfaces, transducer 3 is measured the tension variation of isolated organ 7 smooth muscles, and the tension variation signal is transferred in the computer 4, carries out data analysis and handles, in test process, oxygen bag 8 by pipeline to isolated organ 7 aerating oxygens.
