Abstract
The utility model discloses a be applied to quick experimental culture dish of medicine, it includes the ware body, ware body bottom is provided with the adhesive that does not contain permeable liquid, the adhesive upper end is provided with quick test paper of medicine. The utility model provides a be applied to quick experimental culture dish of medicine can guarantee that the medicine content on the quick test paper of medicine pasted in advance is more accurate and can ensure that the medicine is not influenced at the diffusion in-process.
Description
Technical Field
The utility model relates to a quick experimental field of medicine specifically is a be applied to quick experimental culture dish of medicine.
Background
The bacterial drug sensitivity test is carried out by adopting drug sensitive test paper (generally made of 1m filter paper and with the diameter of 6-7 mm) containing quantitative antibiotics, is a classical bacterial drug resistance test method and is widely applied to the field of medical inspection and related scientific research. The traditional manufacturing process of the drug sensitive test paper is to add the antibiotic with the known concentration into a certain number of circular filter paper sheets, and then paste the filter paper on the solid culture medium inoculated with the test bacteria, although the method is simple and easy, the method still has two problems, firstly, when the antibiotic with the known concentration is added into the certain number of circular filter paper sheets, the antibiotic content in each filter paper is estimated through the average distribution of liquid, but the phenomenon of uneven drug distribution exists; secondly, each piece of prepared drug sensitive paper needs to be manually pasted on a solid culture medium inoculated with test bacteria by a clinical operator, then a drug concentration gradient is formed through natural diffusion of the drug, whether the drug has an antibacterial effect on the bacteria is tested through culture and observation, and the working efficiency is low.
In recent years, with the appearance of commercial drug sensitive (drug sensitive for short) test products, culture devices in which drug sensitive test paper is attached in advance have been provided. However, how to ensure the content of the drug on the pre-pasted drug sensitive test paper to be more accurate becomes a key technology how to ensure that the drug is not influenced in the diffusion process.
SUMMERY OF THE UTILITY MODEL
The utility model provides a be applied to quick experimental culture dish of medicine can guarantee that the medicine content on the quick test paper of medicine pasted in advance is more accurate and can ensure that the medicine is not influenced at the diffusion in-process.
In order to realize the above purpose, the utility model adopts the technical scheme that: the drug sensitive test dish comprises a dish body, wherein an adhesive which is not permeable to liquid is arranged at the bottom of the dish body, and a drug sensitive test paper is arranged at the upper end of the adhesive.
Furthermore, the adhesive is formed by water-based adhesive sticker with completely volatilized volatile solvent, and the diameter of the adhesive area is 0.5-2.5mm and is 0.3-1.1mm higher than the upper end face of the bottom of the dish body.
Furthermore, scales are arranged at the bottom of the dish body and around the adhesive.
The utility model has the advantages that: the filter paper is pre-pasted at the bottom of the culture dish, and then the medicine with accurate concentration is independently filled on each paper, so that the medicine content on each medicine sensitive test paper is highly accurate, and meanwhile, the medicine sensitive test paper is bonded on the adhesive sticker protruding surface with small area, so that the fixing effect of the medicine sensitive test paper can be improved, the medicine in the filter paper is ensured to be in a free diffusion state, and the medicine gradient is formed.

Fig. 1 is a schematic structural diagram of the present invention.
The text labels in the figures are represented as: 1. a dish body; 2. an adhesive; 3. drug sensitive test paper.
Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention is described in detail below, and the description in this section is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.
The utility model discloses a concrete scheme does: the drug sensitive test dish comprises a dish body 1, wherein an adhesive 2 which does not contain permeable liquid is arranged at the bottom of the dish body 1, and a drug sensitive test paper 3 is arranged at the upper end of the adhesive 2.
Preferably, the adhesive 2 is formed by a water-based adhesive sticker with a completely volatilized volatile solvent, an SX088 water-based adhesive sticker can be adopted, no soluble component can be dissolved after drying, and the adhesive belongs to simple physical surface adhesion; the diameter of the area of the adhesive 2 is 0.5-2.5mm, the size of the area can ensure that the drug sensitive test paper 3 can be firmly adhered to the upper end of the adhesive 2 without wasting water-based adhesive sticker, and the upper end surface of the adhesive 2 is 0.3-1.1mm higher than the upper end surface of the bottom of the dish body, so that a gap is formed between the lower end surface of the drug sensitive test paper 3 and the upper end surface of the bottom of the dish body 1, and drug diffusion is facilitated.
Preferably, for the convenience of observation, the bottom of the dish body 1 is provided with scales around the adhesive 2.
The specific manufacturing process comprises the following steps: firstly, dropwise adding a water-based adhesive sticker to the bottom of a dish body 1, forming a hemispherical convex adhesive 2 after the water-based adhesive sticker is naturally dried, wherein the adhesive 2 does not contain permeable liquid and has good adhesion, then adhering the central part of filter paper to the top end of the convex part of the adhesive 2, lightly pressing to firmly adhere the filter paper to the upper end of the adhesive 2, and carrying out sterilization operation on the dish body 1, the filter paper and the like after adhesion is finished; after sterilization, the medicine with accurate concentration is independently injected on each piece of filter paper, so that the filter paper forms the medicine sensitive test paper 3, and the medicine sensitive test paper 3 has a suspension shape with stable adhesive fulcrum, so that the medicine in the medicine sensitive test paper 3 is smoothly diffused in the experimental process.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
