Description

Technical Field

[0001] The utility model relates to the technical field of smear preparation, in particular to a push knife cleaning and drying device. Background Art

[0002] Blood smear staining is a basic means of clinical examination. It plays an important role in the diagnosis of many blood diseases and blood-borne diseases, and can quickly and easily obtain diagnostic results. However, poor preparation and staining of blood smears often make it difficult to identify blood cells, and even lead to wrong diagnostic results. Whether high-quality blood smears can be prepared quickly will affect the subsequent work.

[0003] The push knife is an important tool in the sample preparation step of the blood smear staining method. After the push knife completes the push action, if it contacts the sample without being cleaned in time, it will carry impurities and bacteria to contaminate the blood smear and affect the coating quality of the blood smear, so it must be cleaned. The commonly used cleaning method is to blow dry with air after cleaning, while the traditional air drying method is to use point drying. When using the point drying method to blow dry the push knife, the air outlet needs to move left and right accordingly with the width of the push knife, which will take a certain amount of time and affect the efficiency of cleaning and drying; it is also necessary to install a motor in the mechanism to move the air outlet left and right, and the motor and belt and other structures will occupy a large space in the mechanism. This method also has the probability of not cleaning the pusher clean, or there may be defects such as residual cleaning liquid on the surface of the pusher. The push knife with residual cleaning liquid has an adverse effect on the subsequent coating quality of the blood smear. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] like Figures 1 to 3As shown in , the utility model discloses a push knife cleaning and drying device, which can be used to quickly clean and dry the push knife 900 of the automatic blood smear staining preparation instrument, and can also be applied to the cleaning and drying processes of other similar thin film structures. This push knife cleaning and drying device includes a cleaning module 100, a drying module 200 and a push knife installation module 300. The cleaning module 100 includes a cleaning pool 110 in which the push knife 900 can be immersed for cleaning; the drying module 200 is installed above the cleaning module 100, and two strip blowing outlets 211 are relatively arranged on the drying module 200, and the opening width of each strip blowing outlet 211 is specified to be not less than the width of the push knife 900, that is, each strip blowing outlet 211 can blow out a linear contact airflow, and the strip airflow can form an "air knife". According to actual conditions and different air pressure intensities, when the positions of the drying module 200 and the strip blowing outlets 211 are fixed, as the push knife 900 is gradually moved out of the cleaning pool 110, the linear contact airflows blown out by the two strip blowing outlets 211 can simultaneously blow and dry the opposite sides of the push knife 900, and can scrape and dry the residual liquid at one time, and can be adjusted and applied to different degrees of residual liquid hanging on the wall of the push knife 900.

[0036] In the present embodiment, the push knife 900 is installed on the push knife installation module 300, and the push knife installation module 300 can selectively reciprocate vertically, drive the push knife 900 to move out of the cleaning tank 110 and pass between the two strip-shaped air blowing ports 211, and provide a suitable movement path for the push knife 900; when the push knife 900 needs to be cleaned after a single sheet pushing work, the push knife installation module 300 is first controlled to move vertically downward, and the push knife 900 can pass through the drying module 200 until it is immersed in the cleaning tank 110 and starts cleaning; after cleaning, the push knife installation module 300 is controlled to move vertically upward, and the push knife 900 can be separated from the cleaning tank 110 and pass through the drying module 200 in the reverse direction. At the same time, the two opposite sides of the push knife 900 where the residual liquid is mainly hung pass through the two strip-shaped air blowing ports 211, and can be covered and dried at one time by the two linear contact air flows as the push knife 900 retreats. The push knife 900 can be fully dried stably and quickly, thereby improving the overall work efficiency. Compared with the traditional point drying method, there is no need to move the air outlet, and the structure and function of the drying module 200 are more stable; there is no need to install an additional motor and transmission structure, which saves space and volume, and reduces production costs and working costs; the push knife 900 can be dried in time after cleaning to avoid defects such as deposition and dirt caused by residual cleaning liquid on the surface of the push knife 900, thereby ensuring the coating quality of the blood smear.

[0037] As a preferred embodiment, the opening direction of the strip-shaped blowing port 211 is set at a preset angle to the horizontal plane, and the opening direction of the strip-shaped blowing port 211 is inclined downward. Figure 3As shown in , the blowing direction of the strip-shaped blowing port 211 is set at an angle to the side of the push knife 900, and is inclined in the opposite direction of the moving direction when the push knife 900 moves out of the cleaning pool 110, which can better blow a large amount of flowing residual liquid downward, avoid the residual liquid from repeatedly contaminating the clean and dry push knife part through unreasonable blowing angles, further improve the drying efficiency, and ensure the effect of completing the drying by blowing through the drying module at one time, while also effectively avoiding the instability of the residual liquid being splashed. Exemplarily, the drying module 200 can be provided with a guide plate under each strip-shaped blowing port 211, one end of the two guide plates are respectively connected to the bottom of the two strip-shaped blowing ports 211, and the other ends of the two guide plates are relatively inclined and respectively connected to the two ends of the cleaning pool 110, and the residual liquid blown and scraped from the push knife 900 can be recovered into the cleaning pool 110 along the guide plate, saving the cost of cleaning liquid, and the push knife cleaning and drying device is also neater and cleaner when in use.

[0038] Specifically, the drying module 200 includes a power device, which can supply air to the strip-shaped air outlet 211, and is used to control the strip-shaped air outlet 211 to selectively blow air, and can also adjust the air pressure strength of the air blow for drying, thereby expanding the application scope of the push knife cleaning and drying device; when the push knife installation module 300 moves vertically downward to send the push knife 900 to be cleaned, the power device can control the strip-shaped air outlet 211 to stop blowing air; when the push knife installation module 300 moves vertically upward to make the push knife 900 retreat and pass through the drying module 200, the power device can control the strip-shaped air outlet 211 to keep blowing air, reasonably control the start-up time of the power device, save electric energy, be more environmentally friendly, and extend the service life of the push knife cleaning and drying device. Exemplarily, the power device can be an air pump powered by electricity or manpower, which generates air pressure by continuously compressing air, and is safe and durable.

[0039] Furthermore, the drying module 200 includes a plurality of pipe connectors 220, each strip-shaped blowing port 211 is connected to one end of a plurality of pipe connectors 220, and the plurality of pipe connectors 220 are evenly distributed at a preset distance along the extension direction of the strip-shaped blowing port 211, and the other ends of the pipe connectors 220 are connected to a power device, which can avoid the situation where only one air supply end is connected to the strip-shaped blowing port 211, which may cause insufficient air pressure and fail to fully achieve the strip-shaped blowing effect. Arranging a plurality of pipe connectors 220 makes it easier to form a uniform linear contact airflow, thereby ensuring a quick drying effect.

[0040] In this embodiment, the push knife cleaning and drying device is provided with a power device, and the drying module 200 includes a blowing fixture 210, the power device is sealed and connected to the blowing fixture 210, and a through groove is provided on the blowing fixture 210, and the through groove is arranged opposite to the cleaning tank 110, so that the push knife 900 can pass through the through groove when it moves out of the cleaning tank 110, and blowing channels are arranged on both sides of the through groove, and the blowing channels are connected to the through groove, one end of the blowing channel is sealed and connected to the power device, and the other end is connected to the through groove, forming a strip-shaped The blowing outlet 211, the two strip blowing outlets 211 are both arranged on the same blowing fixture 210, and the blowing fixture 210 is arranged in a "U" shape. The two strip blowing outlets 211 are respectively opened at relative positions of the two arms on the blowing fixture 210, and the push knife 900 passes through the opening inside the blowing fixture 210. Only one power device is used to complete the drying and blowing of the push knife 900, which can further save space and cost, and is suitable for cleaning the push knife 900 of smaller specifications and using the matching drying module 200.

[0041] In another specific implementation of the present embodiment, the push knife cleaning and drying device is provided with two power devices, and correspondingly, the drying module 200 also includes two air blowing fixtures 210, and the power devices are sealed and connected with the air blowing fixtures 210 in a one-to-one correspondence, so as to facilitate the control and replacement of the two air blowing fixtures 210 respectively; the two air blowing fixtures 210 are respectively arranged on opposite sides of the cleaning tank 110, and the push knife 900 passes between the two air blowing fixtures 210 when moving out of the cleaning tank 110; the two air blowing fixtures 210 are both provided with air blowing channels, and one end of the air blowing channel is connected to the power device 210. The force device is sealed and connected, and the other end is connected to the side of the blowing fixture 210 close to the other blowing fixture 210 to form a strip blowing outlet 211, that is, each blowing fixture 210 is provided with a strip blowing outlet 211, and the two blowing fixtures 210 are symmetrically arranged and the relative positions are adjustable, which can better adapt to push knives 900 of different sizes. For push knives 900 of different thicknesses and push knife installation modules 300, the relative positions of the two blowing fixtures 210 can be changed more conveniently by coordinating the settings, with a higher degree of freedom and avoiding interference with other structures.

[0042] Optionally, the drying module 200 further includes a receiving member 230, and the air blowing fixture 210 is welded to the receiving member 230, which can ensure the structural reliability of the push knife cleaning and drying device; or the air blowing fixture 210 is detachably arranged on the receiving member 230, and the drying module 200 is connected to the cleaning module 100 through the receiving member 230, which also avoids the air blowing fixture 210 being directly and repeatedly disassembled and assembled on the cleaning module 100, which affects the strength and function of the cleaning module 100. Specifically, a snap connection or a threaded connection structure is arranged on the air blowing fixture 210 and the receiving member 230, so as to facilitate maintenance and replacement by the staff. It is understandable that the receiving member 230 and the cleaning module 100 are also arranged to be a detachable structural connection, and the receiving member 230 is made of low-cost consumables and can be replaced in time, thereby reducing the use and maintenance costs of the push knife cleaning and drying device. Integrating the drying module 200 with the receiving part 230 makes it more convenient to control and adjust. For example, a slide rail can be set between the blowing fixing part 210 and the receiving part 230 to make it more convenient to adjust the relative positions of the two blowing fixing blocks. The extension direction of the slide rail can be set in a direction close to or away from the push knife 900, or it can be set in parallel with the push knife 900.

At the same time, the design of the cleaning tank 110 should take into account the circulation and distribution of the cleaning liquid to ensure that the ultrasonic wave can evenly act on the push knife 900 to be cleaned, so that the cleaned push knife 900 can be completely renewed. It can be understood that the cleaning module 100 also includes a protective member 130, which is connected to the cleaning tank 110, and the protective member 130 is covered on the ultrasonic transducer 120 to prevent the residual liquid that may be splashed from falling on the ultrasonic transducer 120, so as to prevent the ultrasonic transducer 120 from being corroded by the cleaning liquid or other electrical structures from being immersed in water, thereby causing safety hazards.

[0044] In this embodiment, in order to install the push blade 900 more flexibly and stably, the push blade installation module 300 includes a front installation member 310 and a rear installation member 320. The push blade 900 is detachably clamped between the front installation member 310 and the rear installation member 320, which can facilitate the replacement of different push blades 900, and further improve the adaptability of the push blade cleaning and drying device. Exemplarily, a push blade installation position is provided on the rear installation member 320, and a part of the push blade 900 can be embedded in the push blade installation position. A connecting portion is also provided on the remaining position of the rear installation member 320 avoiding the push blade 900.
