Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smear staining devices, and more particularly to a microbial smear staining device for medical examination. Background Art
[0002] Medical examinations detect the submitted microbial samples. In order to facilitate the observation of microbial cells under an ordinary microbial microscope, it is necessary to stain the microbial samples so as to clearly observe the morphology and structure of the microbial cells. A microbial smear refers to a method of smearing a microbial culture on a glass slide and then observing it. This kind of smear is mainly used to observe dead microorganisms. When making a microbial smear, it is necessary to fix the microbial culture, usually by heating or chemical fixation methods, in order to better observe and identify the microorganisms.
[0003] Before observing a microbial smear, it needs to be stained. The purpose is to better observe and identify the microorganisms. By staining, the microorganisms have different colors or morphologies, making it easier to distinguish and identify them under the microscope. After staining the microbial smear, it is also necessary to rinse the microbial smear with clear water, and some staining methods require multiple stainings and rinsings of the microbial smear. Therefore, the operator needs to walk back and forth between the waste liquid tray and the rinsing sink on the operating table, causing trouble. Content of the Utility Model
[0004] In order to make up for the above deficiencies, the utility model provides a microbial smear staining device for medical examination.
[0005] The utility model is implemented as follows:
[0006] A microbial smear staining device for medical examination includes a fixing mechanism, a staining mechanism, and a cleaning mechanism. The fixing mechanism includes a waste water tank and a fixing seat, and the fixing seat is installed on the inner wall of the waste water tank. The staining mechanism includes a staining box filled with dye, and a first discharging mechanism is installed on one side of the staining box, and the first discharging mechanism extrudes the dye in the staining box. The staining box is installed on the top of the fixing seat. The cleaning mechanism includes a cleaning box filled with clear water, and a second discharging mechanism is installed on one side of the cleaning box, and the second discharging mechanism discharges the clear water in the cleaning box. The cleaning box is installed on the top of the staining box.
[0007] Further, the first discharging mechanism includes a first discharging pipe, which is installed outside the dyeing tank and near the top of the dyeing tank. One end of the first discharging pipe is close to the inner bottom of the dyeing tank, and a first one-way valve is installed at the other end of the first discharging pipe. The output end of the first one-way valve is connected to a second discharging pipe. The first discharging mechanism further includes a discharging cylinder, which is connected to the second discharging pipe. A second one-way valve is connected to the outlet of the discharging cylinder, and the output end of the second one-way valve is connected to a U-shaped pipe.
[0008] Further, a piston is slidably arranged inside the discharging cylinder. One side of the piston is connected to a piston rod, and a handle is installed at the free end of the piston rod.
[0009] Further, the connection between the discharging cylinder and the second discharging pipe is close to the outlet of the discharging cylinder.
[0010] The beneficial effect of adopting the above further scheme is that by holding and pulling the handle, the piston moves and the pressure in the discharging cylinder decreases, so that the dye in the dyeing tank flows into the discharging cylinder through the first discharging pipe and the second discharging pipe. By holding and pushing the handle, the piston moves and the pressure in the discharging cylinder increases, so that the dye in the discharging cylinder flows out through the U-shaped pipe. The user can perform the above operations with one hand, and hold the fixture clamping the smear with the other hand, and make the smear close to the outlet of the U-shaped pipe, so that the dye drops on the smear to complete the staining of the smear.
[0011] Further, the second discharging mechanism includes a third discharging pipe, which is installed outside the cleaning tank and near the bottom of the cleaning tank. A manual valve is installed at the free end of the third discharging pipe, and the output end of the manual valve is connected to a fourth discharging pipe.
[0012] The beneficial effect of adopting the above further scheme is that by opening the manual valve, the clear water in the cleaning tank will flow out through the fourth discharging pipe under the action of water pressure. The user can perform the above operations with one hand, and hold the fixture clamping the smear with the other hand, and make the smear tilt close to the bottom end of the fourth discharging pipe to clean the smear with the clear water.
[0013] Further, a partition is connected between the fixed seat and the inner wall of the waste water tank.
[0014] The beneficial effect of adopting the above further scheme is that the partition divides the space in the waste water tank into a waste water chamber and a waste liquid chamber. The outlet of the U-shaped pipe is located above the waste liquid chamber, and the outlet of the fourth discharging pipe is located above the waste water chamber to distinguish the flushed clear water and the dropped dye.
[0015] Further, a first feeding pipe and a second feeding pipe are respectively installed outside the dyeing tank and the cleaning tank.
[0016] The beneficial effect of adopting the above further solution is that the dye and clear water can be added into the dyeing tank and the cleaning tank by using the first feed pipe and the second feed pipe.
[0017] The beneficial effect of the present utility model is as follows: A microbial smear staining device for medical examination obtained by the above design of the present utility model uses the second discharging mechanism to rinse the smear with clear water, avoiding the user from reciprocating between the operating table and the rinsing sink, so as to facilitate the user to stain the smear.
