Description

Technical Field

[0001] The utility model relates to the field of test paper smearing, in particular to a test paper smearing device. Background Art

[0002] When the laboratory conducts test comparisons, it is sometimes necessary to evenly apply the reagent on the test paper. However, this is usually done manually by using a dropper to drop the reagent on the test paper and then applying it evenly. This may cause the area where the reagent is first dropped to have a high concentration, and the area where it is applied to have a low concentration, resulting in uneven application.

[0003] According to the public patent 202020207035.3, a test paper smearing device for a laboratory is known to include a U-shaped base, the middle part of the upper side of the crossbar of the U-shaped base is fixedly connected to a symmetrical cylinder, the upper ends of the symmetrical cylinders are respectively fixedly connected to the two ends of the lower side of the fixed block, one side of the fixed block is fixedly connected to a cylindrical cover, the upper side of the cylindrical cover is fixedly connected to the lower end of the liquid cylinder through a circular tube, one side of the cylindrical cover is centrally hinged to the central axis of the rotating wheel, a group of grooves evenly arranged in a circle are provided on the arc surface of the rotating wheel, the lower side of the cylindrical cover is fixedly connected to one end of a hose, and the other end of the hose is fixedly connected to a smearing mechanism. The utility model relates to the field of test paper smearing devices, specifically, to a test paper smearing device for a laboratory. This device can apply drugs to the test paper of the laboratory. In the process of realizing this utility model, the inventor found that there are at least the following problems in the prior art that have not been solved. Although the smearing shaft can evenly apply the reagent on the test paper by smearing the test paper, it solves the problem that the reagent is usually dropped on the test paper by a dropper and then evenly applied. This may cause the concentration of the part where the reagent is first dropped to be high, and the concentration of the part where it is applied is low, resulting in uneven application. However, during use, the traditional test paper smearing equipment uses a nozzle to spray the reagent onto the surface of the roller for application. This method of spraying the reagent makes it easy for the reagent to splash onto different positions on the surface of the test paper, resulting in poor uniformity of the reagent at different positions on the surface of the test paper. Moreover, it is still necessary to push the handle back and forth manually for manual application, which is not very convenient. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a test paper smearing device to solve the current traditional test paper smearing device, which uses a nozzle to spray the reagent onto the surface of the roller for smearing. This method of spraying the reagent makes it easy for the reagent to splash onto different positions on the surface of the test paper, resulting in poor uniformity of the reagent at different positions on the surface of the test paper. Moreover, it is still necessary to push the handle back and forth manually for smearing, which is not a very convenient technical problem.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a test paper smearing device, including a concave plate body, and also including:

[0006] The reagent liquid tank is installed on one side of the concave plate body;

[0007] A coating mechanism is connected to one side of the reagent liquid tank, the coating mechanism includes a micro liquid pump, the micro liquid pump is connected to one side of the reagent liquid tank, the end of the micro liquid pump away from the reagent liquid tank passes through the concave plate body and is connected to a first connecting pipe, and the end of the first connecting pipe away from the micro liquid pump is fixedly connected to a rotary joint;

[0008] One end of the rotary joint away from the first connecting pipe is rotatably connected to the second connecting pipe, and one end of the second connecting pipe away from the rotary joint is connected to the rotating cylinder, and a plurality of liquid outlet holes are opened on the outer wall of the rotating cylinder.

[0009] Preferably, a rotating rod is fixed to one end of the rotating cylinder away from the second connecting tube, and one end of the rotating rod away from the rotating cylinder is rotatably connected to a bearing, and a concave plate is installed on one side of the bearing.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model combines a rotating cylinder, a rotating joint and a micro-liquid pump. The micro-liquid pump can draw the reagent liquid in the reagent liquid tank into the rotating cylinder, and the reagent liquid flows out through a plurality of liquid outlet holes on the surface of the rotating cylinder. Moreover, the rotating cylinder can rotate through the rotating joint, so that the reagent liquid can flow out of the liquid outlet holes on the surface of the rotating cylinder in a rotational manner, so that the reagent liquid is evenly applied to the surface of the test paper. Moreover, since an electric slide rail and an electric slider are provided, the electric slide rail and the electric slider can be used to drive the rotating cylinder to move back and forth horizontally for application, eliminating the need for manual pushing by staff, and solving the problem of traditional test paper application equipment that uses a nozzle to spray the reagent onto the surface of the drum for application. This method of spraying the reagent makes it easy for the reagent to splash onto different positions on the surface of the test paper, resulting in poor uniformity of the reagent at different positions on the surface of the test paper. Moreover, it is still necessary to push the handle back and forth manually for application, which is not a very convenient technical problem.

[0016] 2. The utility model combines a fixed cylinder, a spring and a pressure plate, and can utilize the elastic force of the spring in the first fixed cylinder to drive the second fixed cylinder and the pressure plate to move downward.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example 1: A test paper smearing device, see Figures 1 to 3, including a concave plate body 203, and also including: a reagent liquid tank 204, which is installed on one side of the concave plate body 203; a smearing mechanism, which is connected to one side of the reagent liquid tank 204, and the smearing mechanism includes a micro-liquid pump 207, and the micro-liquid pump 207 is connected to one side of the reagent liquid tank 204.

During the rotation of the rotating cylinder 211, the micro liquid pump 207 is turned on, and the reagent liquid in the reagent liquid tank 204 is pumped into the rotating cylinder 211 through the micro liquid pump 207, so that the reagent liquid is caused to flow out of the liquid outlet 214 on the surface of the rotating cylinder 211 in a rotational manner, so that the reagent liquid is evenly applied to the surface of the test paper, which solves the problem of traditional test paper smearing equipment, which uses a nozzle to spray the reagent onto the surface of the drum for smearing. In this way of spraying the reagent, the reagent is easily splashed to different positions on the surface of the test paper, resulting in poor uniformity of the reagent at different positions on the surface of the test paper. Moreover, it is still necessary to push the handle 101 back and forth manually for smearing, which is not a very convenient technical problem.

[0023] For details, see Figure 2 A rotating rod 212 is fixed to one end of the rotating cylinder 211 away from the second connecting tube 210 , and a bearing 213 is rotatably connected to one end of the rotating rod 212 away from the rotating cylinder 211 , and a concave plate 203 is installed on one side of the bearing 213 .

[0028] When using a test paper smearing device, first move the rotating cylinder 211 downward to make the rotating cylinder 211 stick to the top surface of the test paper, then open the electric slide rail 2, the electric slide rail 2 drives the electric slider 201, the electric slider 201 drives the fixed rod 202, the fixed rod 202 drives the concave plate 203 to move back and forth horizontally, the concave plate 203 drives the rotating cylinder 211, the rotating cylinder 211 drives the second connecting tube 210 to rotate through the rotating joint 209, and during the rotation of the rotating cylinder 211, the micro liquid pump 207 is turned on, and the micro liquid pump 207 drives the second connecting tube 210 to rotate through the rotating joint 209. 07 The reagent liquid in the reagent liquid box 204 is drawn into the rotating cylinder 211, so that the reagent liquid rotates and flows out of the liquid outlet 214 on the surface of the rotating cylinder 211, so that the reagent liquid is evenly applied to the surface of the test paper. When the staff holds the device for application, the device moves down and drives the pressure plate 302 to limit and fix the two ends of the test paper, avoiding the test paper from shifting during the application process. Through the elastic force of the spring 303, the second fixed cylinder 301 and the pressure plate 302 will move upward, causing the rotating cylinder 211 to move down and fit closely to the surface of the test paper.
