Description

Technical Field

[0001] The utility model belongs to the technical field of medical detection, and in particular relates to an air-blowing and liquid-discarding device for immunohistochemical preparation. Background Art

[0002] Before immunohistochemical staining, slides must be rinsed or moistened with PBS buffer. However, if excess buffer (referred to as waste solution) is not removed from the slides, it can easily lead to false positives or negatives, or affect the accuracy of experimental results due to edge effects. Currently, waste solution on slides is mainly removed by hand. However, when processing large sample volumes, manually removing waste solution from each slide is not only labor-intensive and time-consuming, but also inefficient. Utility Model Content

[0003] The utility model aims to provide an immunohistochemical slide preparation wind-blowing liquid discarding device to solve the technical problems of heavy workload, long time consumption and low working efficiency caused by the existing manual throwing of glass slides.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A device for blowing away liquid for immunohistochemistry preparation comprises: a box body, the top of which is an open structure; a partition arranged in the box body; the partition comprises a first partition and a second partition, the first partition and the second partition are arranged parallel to each other and a distance is provided between them; a blowing assembly comprises a mounting plate, a base, and a blowing device; the mounting plate is arranged on the outside of the box body, the base is arranged on the mounting plate, and the blowing device is provided on the base; the blowing device faces the partition; the height of the blowing device is higher than the height of the first partition and the second partition.

[0006] Furthermore, the blowing assembly also includes a telescopic device, which is arranged on the mounting plate, and the base is provided at the end of the telescopic rod of the telescopic device; the telescopic rod and the partition are arranged parallel to each other.

[0007] Furthermore, a connecting rod is provided on the base, and a blowing device is provided on the connecting rod; the connecting rod is rotatably connected to the blowing device so that the blowing direction of the blowing device can be adjusted by rotating up and down.

[0008] Furthermore, a clamping plate is provided on the first partition; the clamping plate is provided on the top of the first partition on the side close to the blowing device.

[0009] Furthermore, a support plate is hingedly connected to the top of the second partition so that one side of the support plate can rotate relative to the second partition; a support rod is rotatably connected to the bottom of the support plate so that the support rod can rotate relative to the support plate; a hole is provided at the end of the support rod corresponding to the top of the second partition for clamping the support rod so that the support plate can be stably set at an angle.

[0010] Furthermore, the support plate can rotate relative to the horizontal plane at an angle of 0-20°.

[0011] Furthermore, the box body is movably connected to the first partition plate and the second partition plate; the box body is movably connected to the mounting plate.

[0012] Working principle: This new type of box will place the glass slides washed or moistened with PBS buffer on the first and second partitions, and the excess liquid will be blown away by the air blown out by the blowing device when it is running; the moving speed of the blowing device is controlled by the set telescopic device, so that the glass slides placed at different positions along the length direction of the box body can be blown away by air, thereby blowing away the waste liquid on the glass slides; the extension speed of the telescopic rod of the telescopic device is coordinated with the blowing device to avoid the single glass slide from drying out due to excessive blowing time and excessive blowing volume, which will affect subsequent sample testing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The partitions are used to place glass slides so that the excess liquid on the slides can be blown away by the blowing device, avoiding the need to shake the slides by hand, reducing physical labor and greatly improving work efficiency. Moreover, since the amount of waste liquid on the slides is small, the use of air blowing can shorten the processing time.

[0015] 2. The card plate arranged on the first partition is convenient for stably placing the glass slides to be blown away; the support plate arranged can be rotated to an inclined state relative to the second partition, and the support rod is inserted into the hole of the second partition so that the support plate can be stably tilted, which is convenient for placing the glass slides in an inclined state and convenient for blowing away the waste liquid; since the support plate and the second partition, and the support rods and the support rods are all rotatably connected, it is convenient to turn the support plate to a horizontal state again after the waste liquid is blown away, so as to facilitate operations such as adding reagents and incubating the samples on the glass slides, thereby improving the convenience of operation.

[0016] 3. The connecting rod and the blowing device are rotatably connected, which makes it easy to rotate the blowing device in the up and down directions as needed during use, so as to adjust the wind direction to meet actual use needs.

[0017] 4. Since the amount of waste liquid on the glass slide is not large, the blowing device only needs to blow air on each glass slide for a few seconds. To avoid drying the glass slide, the extension speed of the telescopic rod of the telescopic device can be set so that the extension speed matches the blowing volume of the blowing device, thereby ensuring that the waste liquid is blown away without drying the glass slide.

[0018] 5. The first partition and the second partition are movably connected to the box body. The first partition and the second partition can be removed for easy cleaning and storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate the present invention in conjunction with the accompanying drawings. These examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.

[0028] Example 1

[0029] An immunohistochemical preparation air blowing liquid discarding device, such as Figure 1-Figure 4As shown, it includes: a box body 1, the top of the box body 1 is an open structure; a partition 2, arranged in the box body 1; the partition 2 includes a first partition 21 and a second partition 22, the first partition 21 and the second partition 22 are arranged parallel to each other and there is a distance between them; a blowing assembly 3, including a mounting plate 31, a base 32, and a blowing device 33; the mounting plate 31 is arranged on the outside of the box body 1, the base 32 is arranged on the mounting plate 31, and the base 32 is provided with a blowing device 33; the blowing device 34 faces the partition 2; the height of the blowing device 33 is higher than the height of the first partition 21 and the second partition 22.

[0030] The distance between the first partition and the second partition is smaller than the length of the glass slide. The glass slide has a certain length. When the waste liquid needs to be blown away, the two ends of the glass slide are placed on the first partition and the second partition respectively to prevent the glass slide from falling due to unstable placement, which affects the normal progress of the experiment.

[0031] The partitions can be provided in several groups, so that a plurality of first partitions and second partitions can be provided in the box body, thereby making full use of the space of the box body and processing more slides at one time, thereby improving efficiency.

[0032] The blowing device can be a fan, a blower, etc., and can be powered by mains electricity or a battery.

[0033] A controller can be provided on the side of the box body, and the controller is connected to the blowing device to control the start and stop, direction angle, wind speed, etc. of the blowing device.

[0034] Instructions for use: Place the two ends of the glass slide on the first partition and the second partition respectively, leaving a certain distance between adjacent glass slides; after placement, start the blowing device to blow air towards the glass slide, and when the waste liquid on the glass slide is blown away, the glass slide can be taken away; after all processing is completed, turn off the blowing device.

[0035] The waste liquid on the slide can be blown away, but it cannot be blown dry to avoid affecting the accuracy of subsequent experimental results. Therefore, the operator needs to observe the operation of the blowing device and remove the slide immediately after the waste liquid is blown away, or blow the slide regularly.

[0036] Example 2

[0037] like Figure 1 、 Figure 2-Figure 3 As shown, the blowing assembly 3 further includes a telescopic device 34 , which is arranged on the mounting plate 31 , and a base 32 is provided at the end of a telescopic rod 35 of the telescopic device 34 ; the telescopic rod 35 and the partition 2 are arranged parallel to each other.

[0038] like Figure 1 、 Figure 2-Figure 3 As shown, a connecting rod 36 is provided on the base 32, and a blowing device 33 is provided on the connecting rod 36; the connecting rod 36 is rotatably connected to the blowing device 33 so that the blowing direction of the blowing device 33 can be adjusted by rotating up and down.

[0039] The telescopic device can be equipped with a small low-speed cylinder, an electric push rod, etc., and can be powered by mains electricity or batteries.

[0040] When the telescopic device is in operation, the telescopic rod extends, which drives the base to move, and finally causes the blowing device on the connecting rod to move together; the blowing device blows air toward the glass slide during the movement to blow away the waste liquid on the glass slide; since the amount of waste liquid is not large, the waste liquid can be blown away by controlling the extension speed of the telescopic rod of the telescopic device appropriately in combination with a suitable wind speed; the blowing device can move with the telescopic rod, so that the range of blowing can be controlled, which can ensure that the glass slides placed on different partitions can be blown by the wind, thereby improving work efficiency.

[0041] Example 3

[0042] like Figure 1 、 Figure 4-Figure 6 As shown, a clamping plate 23 is provided on the first partition plate 21 ; the clamping plate 23 is provided on the top of the first partition plate 23 on the side close to the blowing device 33 .

[0043] like Figure 1 、 Figure 4-Figure 6 As shown, the top of the second partition 22 is hinged with a support plate 24, so that one side of the support plate 24 can rotate relative to the second partition 22; the bottom of the support plate 24 is rotatably connected to a support rod 25, so that the support rod 25 can rotate relative to the support plate 24; the end of the support rod 25 is provided with a hole corresponding to the top of the second partition 22 for clamping the support rod 25, so that the support plate 24 can be stably set at an angle.

[0044] like Figure 5 As shown, the support plate 24 can rotate relative to the horizontal plane by an angle of 0-20°.

[0045] A clamping plate is provided on the first partition plate to facilitate clamping the glass slides placed on the first partition plate and the second partition plate, playing a certain limiting role and preventing the glass slides from sliding off.

[0046] A support plate is hingedly provided on the top of the second partition, so that the support plate can rotate relative to the second partition, thereby making the support plate in an inclined state, and the provided support rod can be rotated to fit into the hole on the top of the second partition, thereby making the support plate in a stable inclined state; at this time, the glass slides placed on the first partition and the second partition are in an inclined state, which facilitates the wind blown out by the blowing device to blow away the waste liquid on the glass slides; the support rod is rotatably connected to the support plate, so that the support rod can rotate up and down relative to the support plate; a storage groove can be provided at the bottom of the support plate, so that the support rod can be rotated and placed in the storage groove when the support plate does not need to be tilted.

[0047] When in use, first adjust the support plate to an inclined state and support it firmly with a support rod, then place the glass slide, and then start the blowing component to blow away the waste liquid; because after the waste liquid is blown away, reagents need to be added to the glass slide and incubated, and the glass slide needs to be placed horizontally at this time; therefore, after the waste liquid is blown away, the support plate can be taken out and put away from the hole on the top of the second partition, and the support plate can be adjusted from an inclined state to a horizontal state, so that the glass slide is placed in a horizontal state, which is convenient for subsequent operation and processing.

[0048] Multiple groups of first partitions and second partitions can be set in the box body to place more glass slides for waste liquid blowing away. When there are multiple groups, the order of placing the first partitions and the second partitions should be appropriate so that the glass slides placed in each group are in the same direction. The glass slides in each group can be staggered and placed, all obliquely toward the side where the blowing component is installed, so that a large number of glass slides can be processed in a shorter time, reducing the waste liquid processing time and improving work efficiency.

[0049] Example 4

[0050] like Figure 1 、 Figure 4 As shown, the box body 1 is movably connected to the first partition plate 21 and the second partition plate 22; the box body 1 is movably connected to the mounting plate 31.

[0051] The first partition and the second partition are both movably connected to the box body. The specific connection method can be that slots are provided at the positions of the two ends of the first partition and the second partition corresponding to the inner side of the box body, and the movable connection is achieved by plugging; the movable connection method can facilitate the selection of the number of the first partition and the second partition according to actual needs; at the same time, it is also convenient to remove the first partition and the second partition for cleaning and storage.

[0052] The mounting plate and the box body can be connected by screws, so that they can be quickly removed when the telescopic device and the blowing device need to be repaired or replaced.

[0053] In the present utility model, the specific models of the controller, blowing device, telescopic device, etc. are not the improvements created by the present invention and will not be described in detail here.
