Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically relates to a disposable sterile inoculation and smear device. Background Art

[0002] An inoculation loop is a commonly used tool in microbiology for studying bacteria and fungi on semi-solid media. Previously, inoculation loops were made of metal and could be reused. Each time a sample was inoculated, it could be sterilized by heating over a fire. Due to the inconvenience of its operation and the progress of modern technology, it was subsequently evolved into a disposable sterile inoculation loop, which is made of elastic plastic material. A new inoculation loop is replaced for each sample, thus avoiding misidentification caused by incomplete sterilization. However, in microbiological tests, after inoculating a sample onto a culture dish using an inoculation loop, a smear operation still needs to be directly performed on the sample. Usually, when using a traditional sample inoculation loop for smearing, it will result in disadvantages such as uneven smearing, a relatively thick smeared sample, and being difficult to observe under a microscope. And if other tools are used for smearing, the operation is complex and a large amount of time and resources are wasted.

[0003] When performing microbiological identification, usually after inoculation, further smearing is required for identification under a microscope. However, when inoculating and smearing, tools need to be replaced, which brings many inconveniences to the operator and increases the cost at the same time; if only an inoculation loop is used for both operations, the disadvantages of uneven and too thick smearing will be exposed, and it is very difficult to perform good identification and judgment under a microscope.

[0004] In the prior art, Chinese Patent CN 217297836 U discloses a set of detachable microbiological inoculation tools, including a metal handle and an inoculation end. One end of the metal handle is provided with a threaded hole, and the end of the inoculation end is threadedly connected to the threaded hole. The other end of the inoculation end includes an inoculation wire tip, an inoculation loop tip, a spreader tip, an inoculation hoe tip, and an inoculation hook tip; the experimenter can select different inoculation tool tips according to the microorganisms to be inoculated and cooperate with the metal handle for use, screw the inoculation end in or out, and replace different inoculation ends, which is convenient for the experimenter to use and saves the cost of purchasing tools at the same time. Only the inoculation end needs to be purchased; when screwing the inoculation end in or out, a rod-shaped protrusion can be used to screw it out, which is convenient for screwing the inoculation end tightly and loosening it for removal.

[0005] In the prior art, by replacing the inoculation end, various inoculation activities are facilitated, but the use process is relatively complex and time is easily wasted.

[0006] In view of this, the utility model provides a disposable sterile inoculation and smear device, which makes it convenient for the operator to operate within the range of controllable cost when using the inoculation loop and saves time. Summary of the Utility Model

[0007] The utility model is completed by setting a smear plate 2 and an inoculation loop 5 at one end of the rod body 1, so that one inoculation loop can be used for two purposes, avoiding the inconvenience caused by multiple replacements.

[0008] The utility model provides a disposable sterile inoculation and smear device, which includes a rod body 1 and a smear plate 2 arranged at one end of the rod body 1. The smear plate 2 is fixedly connected to the rod body 1. A flocked smear 3 is fixedly arranged on one side of the smear plate 2, and an inoculation loop 5 is fixedly connected to the other side through a connecting rod 4. After using the inoculation loop 5 to inoculate a sample, the flocked smear 3 is used to smear the inoculated sample. When in use, there is no need to replace tools, avoiding waste of time and at the same time avoiding the disadvantages of uneven and too thick smears when using a single smear device.

[0009] Further, a holding part 6 is arranged on the rod body 1, and the holding part 6 has a certain protrusion to facilitate the user's grasping.

[0010] Further, the rod body 1 is made of a material with a certain elasticity to facilitate the operation during inoculation and smearing.

[0011] Further, a plurality of connecting rods 4 are arranged to improve the connection stability between the smear plate 2 and the inoculation loop 5.

[0012] Furthermore, the connecting rod 4 has a certain length to avoid the inoculation loop 5 contaminating the flocked smear 3 during inoculation.

[0013] Further, the rod body 1, the smear plate 2, the connecting rod 4 and the inoculation loop 5 are integrally formed.

[0014] Compared with the prior art, the technical advantages of the disposable sterile inoculation and smear device provided by the utility model are as follows:

[0015] The disposable sterile inoculation and smear device provided by the utility model can perform two operations of inoculation and smearing without replacing tools, which is convenient for the operator to use and saves the operator's time; by setting the flocked smear 3 as the smearing tool for the sample, there will be no material debris left on the glass slide to interfere with the examiner's judgment of microorganisms, and viscous specimens such as sputum can be smeared evenly with a controllable smearing thickness.

[0016] Other features and advantages of the utility model will be described in detail in the subsequent specific implementation part. BRIEF DESCRIPTION OF THE DRAWINGS
