The production of blood smears includes two steps: the production of glass slides and staining. However, poor preparation and staining of blood smears often make it difficult to identify cells and even lead to incorrect conclusions. Whether high-quality blood smears can be prepared quickly will affect the progress of subsequent work. Poor production of blood smears may even affect the identification of blood cells.
[0003] During the pushing process of the automatic blood smear preparation instrument, the glass slide after dripping blood needs to be transported to the pushing structure. The push knife of the pushing structure contacts the blood drop, and a blood film for observing cell morphology is formed on the blood-carrying glass slide. Then, the glass slide continues to be transported to the card unloading structure, and the blood-stained push knife needs to be cleaned to prevent contamination of the blood on the next glass slide and resulting in deviation of the test results.

[0033] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.
[0034] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements.

[0035] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them.

The first feature being "below", "below the", and "under the" second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the first feature has a lower horizontal height than the second feature.
[0036] In the description of this embodiment, the terms "above", "below", "right", etc., the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.
[0037] The present utility model discloses a push knife head mechanism and a knife head cleaning system. Specifically as Figure 1 and Figure 2As shown in the figure, the push knife head mechanism 100 includes a knife head seat 110, a downward pressing fixing member 120, an upward turning fixing member 130 and an elastic linkage member. Among them, the knife head seat 110 can reciprocate in the vertical direction; the downward pressing fixing member 120 is detachably installed with a push knife 101 and is rotatably connected to the knife head seat 110. The downward pressing fixing member 120 can control the push knife 101 to switch between the working state and the cleaning state. When the push knife 101 is in the cleaning state, the length extension direction of the push knife 101 is the vertical direction; the upward turning fixing member 130 is rotatably connected to the knife head seat 110, and the relative rotatable angle between the upward turning fixing member 130 and the knife head seat 110 is greater than a preset angle, and the push knife head mechanism 100 is provided with a large-angle movable structure; the upward turning fixing member 130 is provided with a support member 132, and the support member 132 can support and abut against the cleaning mechanism 200. When the push knife 101 needs to be cleaned, during the process of the knife head seat 110 moving vertically downward, the relative sliding of the support member 132 with respect to the cleaning mechanism 200 can cause the upward turning fixing member 130 to rotate a preset angle along the turning direction. At the same time, an elastic linkage member is added. One end of the elastic linkage member is connected to the upward turning fixing member 130, and the other end of the elastic linkage member is connected to the downward pressing fixing member 120. The elastic linkage member drives the downward pressing fixing member 120 to rotate in the opposite direction of the turning direction. The turning direction is as Figure 1 marked in the figure, which can control the push knife 101 to change its direction so that the push knife 101 can be switched from the working state to the cleaning state. The vertical setting of the push knife 101 can fully and efficiently penetrate for cleaning, and the operation steps are simple and stable; when the size of the assembled push knife 101 is too large and deeper cleaning is required, the knife head seat 110 continues to move vertically downward. Since the relative upward turning angle between the upward turning fixing member 130 and the knife head seat 110 is designed to be a large angle during design, the upward turning fixing member 130 can continue to rotate along the turning direction. The push knife 101 remains in the cleaning state and can move vertically downward together with the knife head seat 110. The push knife 101 can be cleaned more deeply and completely, further ensuring that the push knife 101 can enter the cleaning pool at different depths within a reasonable limit, so that the push knife head mechanism 100 can meet the cleaning requirements of different models of push knives 101 and has a wider application range. Exemplarily, the preset angle can be specifically set according to the actual matching structure between the upward turning fixing member 130 and the downward pressing fixing member 120. It is necessary to ensure that when the upward turning fixing member 130 rotates the preset angle, the push knife 101 installed on the downward pressing fixing member 120 can be in a vertical cleaning state.
[0038] Furthermore, a first limit piece 111 is provided on the cutter head seat 110, which is located directly above the downward pressing fixing piece 120. When the cutter head seat 110 moves vertically downward and the upward flipping fixing piece 130 begins to flip in the flipping direction, the elastic linkage piece will pull the downward pressing fixing piece 120, thereby causing the push knife 101 to perform a downward pressing action until the downward pressing fixing piece 120 abuts against the first limit piece 111. The downward pressing fixing piece 120 can stop rotating. When the upward flipping fixing piece 130 continues to rotate in the flipping direction, the push knife 101 can remain in a clean state and can enter the cleaning pool for cleaning. The push knife head mechanism 100 is more stable during cleaning.
[0039] Preferably, the push knife tool head mechanism 100 also includes an elastic reset member, one end of the elastic reset member is connected to the upward flipping fixing member 130, and the other end of the elastic reset member is connected to the tool head seat 110. When the upward flipping fixing member 130 flips along the flipping direction, the tool head seat 110 maintains the movement trajectory along the vertical downward direction unchanged, the relative rotation angle between the upward flipping fixing member 130 and the tool head seat 110 becomes larger, and the elastic reset member is stretched and has elastic potential energy; after the push knife 101 is cleaned, the upward flipping fixing member 130 no longer needs to continue to increase the rotation angle, and the tool head seat 110 starts to move vertically upward. Under the action of the elastic reset member, the relative rotation angle between the upward flipping fixing member 130 and the tool head seat 110 becomes smaller, and the upward flipping fixing member 130 can be automatically reset by the elastic reset member.
[0040] In this embodiment, the upward-flipping fixing member 130 is provided with a second limiting member 131, and the second limiting member 131 is arranged parallel to and staggered with the rotating axis of the upward-flipping fixing member 130. When the tool head seat 110 moves vertically upward and the upward-flipping fixing member 130 begins to rotate in the opposite direction of the flipping direction to reset, the second limiting member 131 abuts against the opening of the tool head seat 110. At this time, the elastic linkage member is not subjected to tension and is exactly at its original length. The push knife 101 is in a working state, which further stabilizes the push knife tool head mechanism 100 and limits the upward-flipping fixing member 130.
[0041] Optionally, the pressing fixing member 120 specifically includes a mounting portion, a rotating portion 121 and a linkage portion. The rotating portion 121 is rotatably connected to the cutter head seat 110. The mounting portion and the linkage portion are respectively arranged at both ends of the rotating portion 121. In order to install the push knife 101 more flexibly and stably, the mounting portion includes a lower cover plate portion 122 and an upper cover plate portion 123. The push knife 101 is detachably clamped between the upper cover plate portion 123 and the lower cover plate portion 122. The upper cover plate portion 123 presses the push knife 101 onto the lower cover plate portion 122. Exemplarily, the upper cover plate portion 123 and the lower cover plate portion 122 are fixed by a cross screw, which can pass through the upper cover plate portion 123 and the push knife 101 in sequence and be screwed to the lower cover plate portion 122, so that the staff can conveniently disassemble and replace.
[0042] For better cleaning effect, when installing the push knife 101, set the width extension direction of the push knife 101 to the horizontal direction. At the same time, the axial extension direction of the pressing shaft member 114 is parallel to the width extension direction of the push knife 101. When the push knife 101 rotates, its width extension also remains flush with the horizontal direction, thereby ensuring a better cleaning effect.
[0043] Specifically, the tool head seat 110 includes a base 112, an upward-turning shaft member 113, and a downward-pressing shaft member 114. The upward-turning shaft member 113 and the downward-pressing shaft member 114 are respectively inserted into the base 112. The upward-turning fixing member 130 is rotatably sleeved on the upward-turning shaft member 113. Similarly, the downward-pressing fixing member 120 is rotatably sleeved on the downward-pressing shaft member 114. In this embodiment, the tool head seat 110 further includes a first locking member 115 and a second locking member 116. The upward-turning shaft member 113 can be axially locked with the base 112 through the first locking member 115, and the downward-pressing shaft member 114 can be axially locked with the base 112 through the second locking member 116, further ensuring the insertion stability of the base 112 with the upward-turning shaft member 113 and the downward-pressing shaft member 114, and preventing the upward-turning shaft member 113 and the downward-pressing shaft member 114 from falling out or sliding out. Exemplarily, the cross-section of the base 112 is in a "C" shape. The two ends of the upward-turning shaft member 113 are respectively inserted into both sides of the opening of the base 112, and the downward-pressing shaft member 114 is also arranged in the same way. The two first locking members 115 arranged at the two ends of the upward-turning shaft member 113 and the two second locking members 116 arranged at the two ends of the downward-pressing shaft member 114 are both snap rings. A snap ring is a type of shaft retaining ring, which is pressed into the groove by means of its elasticity and the pulling-type opening, and is axially positioned, locked or stopped with the side surface of the snap ring passing through the end surface of the hole.
[0044] Specifically, the support member 132 is set as a roller, and the roller can roll relative to the cleaning mechanism 200, which improves the freedom degree of relative sliding between the support member 132 and the cleaning mechanism 200, avoids the contact position between the two from being rough and worn due to frictional resistance, and extends the service life of the push knife tool head mechanism 100. In this embodiment, the axle of the roller is installed on the upward-turning fixing member 130, and the rim of the roller is also axially locked and positioned with the axle by using a snap ring.
[0045] Specifically, such as Figure 2The working process of the push knife 101 extending into the cleaning tank 221 shown in the figure is as follows. The present utility model also provides a tool head cleaning system for cleaning the push knife tool head mechanism 100 in any of the above-mentioned solutions. The tool head cleaning system includes a cleaning mechanism 200. Among them, a support member 132 is provided on the upward-flipping fixing member 130 of the push knife tool head mechanism 100; and the cleaning mechanism 200 includes two cleaning blocking members 210 and a cleaning module 220. The two cleaning blocking members 210 are symmetrically connected to both sides of the cleaning module 220. Each cleaning blocking member 210 is provided with a support surface 211. The two ends of the support member 132 are respectively supported on the two support surfaces 211 in a one-to-one correspondence. The support member 132 is in sliding contact with the cleaning blocking member 210. The structure is simple and ensures that the push knife 101 does not tilt during the cleaning process, ensuring a good cleaning effect; the cleaning module 220 is provided with a cleaning tank 221. When the push knife 101 is in the cleaning state, the push knife 101 can extend into the cleaning tank 221 and move along the depth direction of the cleaning tank 221. It can not only stably clean the push knife 101, but also flexibly adjust the cleaning depth, improving the perfection and adaptability of cleaning different push knives 101. In this embodiment, two support members 132 are respectively provided at both ends of the upward-flipping fixing member 130, corresponding to the two cleaning blocking members 210 respectively. When the push knife 101 needs to be cleaned, the tool head seat 110 moves vertically downward. When both support members 132 come into contact with the cleaning blocking members 210, since the tool head seat 110 still continues to move vertically downward, the elastic reset member starts to work and elongates, and the upward-flipping fixing member 130 starts to flip upward, thereby driving the elastic linkage member to start working, the downward-pressing fixing member 120 rotates, and the push knife 101 starts to be pressed down to the cleaning state, and then vertically enters the cleaning tank 221; because the two support members 132 are respectively located on both sides of the upward-flipping fixing seat and are fixed, when both support members 132 keep contacting the cleaning blocking members 210, the push knife tool head mechanism 100 will not tilt, and naturally the push knife 101 will not tilt when extending into the cleaning pool, thus solving the problem of the tilt of the push knife 101.
[0046] It can be understood that if the tool head seat 110 continues to move downward at this time, since the upward-flipping rotation angle of the upward-flipping fixing member 130 is designed to be a large angle exceeding the preset angle during design, the push knife 101 can still continue to penetrate deep into the cleaning tank 221 at this time, so as to achieve the effect of flexibly adjusting the depth of the push knife 101 extending into the cleaning tank 221, and can adaptively clean push knives 101 with different length specifications.
[0047] Preferably, another function of the second limiting member 131 is to prevent the pulling force generated when the elastic reset member restores deformation from causing the upward-flipping fixing member 130 to quickly rotate back to its original position, resulting in a collision between the roller and the tool head seat 110, damaging the roller and affecting the subsequent rolling effect; a silica gel anti-collision pad can also be added to the second limiting member 131 to further protect the service life of the tool head cleaning system.
[0048] Further, the cleaning mechanism 200 further includes a drying module 230. The drying module 230 is disposed above the cleaning module 220 and is used for drying the push knife 101. In this embodiment, the drying module 230 is provided with a drying tank which is laterally grooved. The push knife 101 can be selectively placed in the drying tank. After the push knife 101 is cleaned in the cleaning tank 221, the tool head seat 110 starts to move vertically upward. Under the action of the elastic reset member, the upward-flipping fixing member 130 gradually resets, and the push knife 101 starts to move upward. When the push knife 101 rises to the height of the drying tank, it can be dried, so that the tool head cleaning system achieves the effect of integrating cleaning and drying.
[0049] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
