Detailed Description
The invention will be described in detail with reference to the following drawings and specific embodiments:
as shown in fig. 1 to 3
A disposable culture dish for detecting bacteriostatic activity of a laboratory medicament comprises a dish cover 1 and a dish bottom 2. The dish bottom 2 is a circular shell with an opening at the top. The dish cover 1 is covered on the dish bottom 2. The dish bottom 2 is detachably connected with a sample adding part. The sample adding component comprises an annular bracket 31, a linear bracket 32 and an oxford cup 33. The annular support 31 is of a circular ring plate-shaped structure. The linear support 32 is a strip-shaped plate-shaped structure. The ends of the linear support 32 are fixed to the side walls of the toroidal support 31. The linear support 32 and the ring support 31 are on the same horizontal plane. The distance from one end, far away from the annular support 31, of the linear support 32 to the annular center of the annular support 31 is equal to the radius of the outer side of the dish bottom 2, the tail end of the linear support 32 is just erected on an opening in the top end of the dish bottom 2, the bottom of the annular support 31 is fixedly connected with the end part of the oxford cup 33, and the oxford cup 33 is perpendicular to the annular support 31. The oxford cups 33 are tubular, the number is 3, and the distance between each oxford cup 33 is equal. The length of the oxford cup 33 is equal to the height of the inner side of the dish bottom 2. The annular support 31 is provided with a drip hole 311 penetrating through the annular support 31, and the drip hole 311 is communicated with the oxford cup 33. The annular support 31, the linear support 32 and the oxford cup 33 are integrated. When the sample adding device is used, a sample adding component is placed on the dish bottom 2, the linear support 32 just covers the opening at the top end of the dish bottom 2, the oxford cup 33 is positioned in the dish bottom 2, and one end, far away from the annular support 31, of the oxford cup 33 is matched with the bottom of the dish bottom 2. This use novel three oxford cup 33 of adopting links together through 31 mutual indirect of ring carrier, and is more stable, emptys the problem easily when having avoided the single use of oxford cup 33. The medicine is not easy to topple when being added and transferred, the practicability is better, and the reliability of the experimental result is higher.
The horizontal width of the annular support 31 is greater than the internal diameter of the oxford cup 33 by 1 cm. When adding the medicine in traditional culture dish, experimental operating personnel will be with the liquid medicine drop on the rim of oxford cup 33 top carelessly a little, even directly drip into the dish in. Use the utility model discloses the time, even experiment operating personnel is not very standard, when the liquid medicine drops at oxford cup 33 outer wall, the liquid medicine can be stayed on ring carrier 31, can not the support flow in the ware, avoids multiple operation, can effectual improvement experiment speed.
The aperture of the dripping hole 311 is consistent with the inner diameter of the oxford cup 33, so that the medicine can be conveniently added, and the use is smooth. When the dropping hole 311 is too large, the liquid medicine is easy to stay on the step formed by the oxford cup 33 and the dropping hole 311, so that the accuracy of the experiment is affected, and the precision is not high. When the dropping hole 311 is too small, the medicine is not easy to be added, and the determination efficiency is not high.
The laboratory is with the disposable culture dish that is used for medicine antibacterial activity to detect and is transparent plastics material. The transparent plastic material is convenient for the experimenter to observe, and can master the measured data in real time.
The bottom of the linear bracket 32 is provided with a fixture block 34, and the fixture block 34 is positioned at one end of the linear bracket 32 far away from the annular bracket 31. At least three clamping blocks 34 are arranged, and one side of each clamping block 34, which is far away from the annular bracket 31, is matched with the inner side of the dish bottom 2. During the use, fixture block 34 is contradicted each other with the ware end 2 and is fixed the application of sample part in the ware end 2, avoids application of sample part horizontal migration, influences the survey precision.
The oxford cup 33 comprises a first cup body 331 and a second cup body 332 vertically sleeved outside the first cup body 331, one end of the first cup body 331 is fixedly connected with the annular support 31, a first convex ring 3311 is fixedly connected to the outer side of the other end of the first cup body 331, the inner diameter of the second cup body 332 is larger than the outer diameter of the first cup body 331, a second convex ring 3321 is fixedly connected to the inner side of one end of the second cup body 332 close to the annular support 31, and the inner diameter of the second convex ring 3321 is smaller than the outer diameter of the first convex ring 3311. The second cup 332 is constrained to slide on the outer wall of the first cup 331 by the cooperation of the second collar 3321 and the first collar 3311. The first cup 331 is three fifths of the height of the inner side of the dish bottom 2, and the second cup 332 is the same length as the first cup 331. During the use, the application of sample part lid is on the dish end 2, and oxford cup 33 is located the dish end 2, and second cup 332 slides down naturally under the effect of gravity and laminates mutually with the dish end 2. When the oxford cup 33 is manufactured in a factory, the higher the length accuracy of the oxford cup 33 is, the higher the manufacturing cost is. The utility model discloses can avoid oxford cup 33 because the problem at the bottom of the ware 2 of mistake can not be met to the manufacturing process length precision, can cooperate and use the ware end 2 of co-altitude not, application scope is wider, and the cost of manufacture is also lower.
The first convex ring 3311 is made of rubber, so that the sealing performance between the first cup body 331 and the second cup body 332 can be effectively improved, and the liquid medicine is prevented from overflowing from the space between the first cup body 331 and the second cup body 332.
During the experiment, take out the application of sample part, will melt in the sterilization culture medium pours into ware end 2, wait that it cools off fixed back, then evenly paint the experiment bacterial strain in ware end 2, install the application of sample part on ware end 2 again, the automatic laminating with ware end 2 of oxford cup 33 under the effect of gravity, add the medicine in oxford cup 33 at last. And after the test is finished, measuring the size of the bacteriostatic zone, recording, and cleaning in order.
Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will understand that the present invention can be modified or replaced with other embodiments without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims. The technology, shape and construction parts which are not described in detail in the present invention are all known technology.
