[0002] When studying and diagnosing bone tissue changes and bone diseases, it is often necessary to make bone tissue specimens into sections for microscopic diagnosis or providing diagnostic basis. Bone contains about 50% water, 30 - 40% organic matter, and the rest are inorganic salts. The inorganic salts contain 85% calcium phosphate, a small amount of calcium carbonate and other substances. Since bone and other calcified tissues are hard and not conducive to sectioning, before making bone tissue sections, the inorganic salts must be dissolved, leaving only the organic salts. The bone still maintains its original shape and internal structure, but becomes soft and bendable, which is conducive to sectioning.

[0003] Currently, the method commonly used by medical institutions to remove calcium from bone specimens is to fully fix the bone tissue with a fixing solution, then rinse the specimen with running tap water to remove some metal ions and chloride ions that interfere with staining in the tissue. Then, place the bone specimen in a glass bottle or other acid-resistant container containing decalcifying solution, and regularly check and replace the decalcifying agent. Depending on the size of the bone tissue block and the type of bone, the decalcification time is from dozens of minutes to several days at room temperature. After decalcification is completed, thoroughly rinse the specimen with running tap water.

[0004] In the prior art, due to the limited number of flushing nozzles, when multiple bone specimens need to be examined, the tissue blocks of multiple bone specimens can only be placed in one container for flushing, which may lead to cross-contamination between different bone specimens and affect the accuracy of subsequent diagnosis.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0032] In the prior art, due to the limited number of flushing nozzles, when multiple bone specimens need to be inspected, the tissue blocks of multiple bone specimens can only be placed in one container for flushing, which may lead to cross-contamination between different bone specimens and affect the accuracy of subsequent diagnosis.

[0033] Based on the above problems in the prior art, the present utility model provides a decalcification flushing box for preventing cross-contamination, as Figure 1 and Figure 3 shown. The decalcification flushing box for preventing cross-contamination includes: a box body 100, in which several baffles 110 are arranged inside the box body 100. The several baffles 110 divide the interior of the box body 100 into multiple placement cavities 101. A filter screen 120 is arranged circumferentially on the outer side of the box body 100, and the height of the filter screen 120 corresponds to that of the baffles 110; a cover body 200, in which multiple diversion holes 210 are arranged inside the cover body 200. One ends of the multiple diversion holes 210 are arranged corresponding to the multiple placement cavities 101, and the other ends of the multiple diversion holes 210 are in a through-through setting with a conduit 220 arranged on the other side of the cover body 200; a connecting pipe 300, which is tightly sleeved and connected with the conduit 220.

[0034] The present utility model divides the water flow into multiple strands by arranging multiple placement cavities 101 inside the box body 100, isolating the placement cavities 101 with baffles 110, draining water through the filter screen 120 on the outside, and arranging multiple diversion holes 210 corresponding to the placement cavities 101 on the cover body 200. The diversion holes 210 are connected to the flushing nozzle through the connecting pipe 300, so as to achieve the effect of simultaneously flushing multiple bone specimens in isolation and effectively avoid cross-contamination between bone specimens.

[0035] In the above embodiment, as Figure 1As shown, the main body of the decalcification flushing box for preventing mutual contamination of the utility model is composed of a box body 100, a cover body 200 and a connecting pipe 300, wherein the box body 100 is used to hold bone specimens, and is made of water-tight plastic or metal material. A plurality of baffles 110 are arranged inside the box body 100, and the baffles 110 are also made of water-tight plastic or metal material. When actually arranged, the box body 100 is arranged in a rectangular shape, and the baffles 110 are arranged along the length direction and the width direction of the box body 100, and are tightly fixedly connected, so as to seal the box body 100. The interior is divided into a plurality of placement cavities 101, and the placement cavities 101 are used to place bone specimens. Since a plurality of placement cavities 101 are provided, a plurality of bone specimens can be placed therein, and adjacent placement cavities 101 are separated by baffles 110 to avoid mutual contamination. Correspondingly, a leakage net is provided on the outside of the box body 100, and the leakage net is arranged around the outside of the box body 100, and the height of the leakage net corresponds to the height of the baffle 110. The leakage net is convenient for the discharge of water during the flushing process, and can prevent the bone specimen from leaving the placement cavity 101, thereby ensuring continuous stability during the flushing process.

[0036] The cover is used to buckle on the baffle 110 and the filter 120 above the box body 100 to further ensure that the bone specimen will not fall out of the box body 100. Since the number of nozzles (faucets) used for flushing in medical institutions is limited, and the water flow of conventional nozzles (faucets) is columnar and the flushing range is limited, therefore, Figure 3 As shown, in this embodiment, a plurality of guide holes 210 are arranged inside the cover body 200, one end of the plurality of guide holes 210 is arranged corresponding to the plurality of placement cavities 101 inside the box body 100, and the other end of the guide hole 210 is arranged to intersect with the conduit 220 arranged on the other side of the cover body 200. In addition, the conduit 220 is tightly connected through the connecting pipe 300, and then connected to the nozzle (faucet) in the prior art through the connecting pipe 300, so that water can enter the plurality of guide holes 210 inside the cover body 200 along the connecting pipe 300 and the conduit 220, and flow into the plurality of placement cavities 101 respectively along the plurality of guide holes 210, so as to form a corresponding flushing effect on the bone specimens in the plurality of placement cavities 101.

[0037] The utility model divides a limited flushing water flow into multiple streams, and flushes the bone specimens in the corresponding placement cavities 101 of the multiple box bodies 100, effectively solving the problem of limited flushing nozzles (faucets) in medical institutions in the prior art. At the same time, due to the arrangement of the baffle 110 and the filter screen 120 on the box body 100, the multiple placement cavities 101 are not interconnected, which not only keeps the flushing process continuous but also avoids mutual contamination between the multiple bone specimens, thereby ensuring the accuracy of subsequent diagnosis.

[0038] It should be noted that when the box body 100 is partitioned by the baffle 110, one baffle 110 should be arranged along the center line of the box body 100 in the length direction, and the remaining baffles 110 can be arranged vertically on both sides of this baffle 110, so that each placement cavity 101 corresponds to a baffle 110 and a filter screen 120.

[0039] Furthermore, in the above embodiment, as Figure 1 and Figure 2 shown, a surrounding plate 150 is also circumferentially arranged on the outer side of the above box body 100. The surrounding plate 150 is a watertight plate member, made of plastic or metal material. The surrounding plate 150 is hermetically connected to the box body 100, and the surrounding plate 150 is arranged at a predetermined distance higher than the bottom plate 130 of the box body 100. At the same time, the side of the above baffle 110 is hermetically connected to the surrounding plate 150, and the above filter screen 120 is fixedly arranged above the surrounding plate 150. That is, after the above settings, the surrounding plate 150, the baffle 110 corresponding to the placement cavity 101, and the bottom plate 130 of the box body 100 together form a cup-shaped structure, which can hold a certain amount of liquid. When actually flushing water, the bone specimen in the placement cavity 101 can be immersed in the liquid held by the corresponding surrounding plate 150 and baffle 110, so as to achieve the effect of both immersion and flushing water, and improve the flushing efficiency.

[0040] Based on the above embodiment, in another feasible implementation manner of the present utility model, as Figure 1 shown, in the prior art when making bone specimens, it includes an impregnation operation, that is, the clearing agent in the tissue is replaced by impregnation with wax. After the paraffin penetrates into the tissue, the tissue becomes hard as a wax block after freezing, which is conducive to cutting into thin slices. In this step, the medical device used to hold the wax block is called a tissue wax block box 400, that is Figure 1 the style in Figure 2 and Figure 4 shown. When flushing water for the bone specimen in the tissue wax block box 400, the bone specimen in the tissue wax block box 400 needs to face the water flow. Therefore, in this embodiment, as

[0041] shown, on the bottom plate 130 of the above box body 100, at the positions corresponding to multiple placement cavities 101, a tenon group is respectively arranged. The tenon group specifically includes two protruding tenons 140 arranged at a predetermined distance. By clamping the relative two sides of the tissue wax block box 400 with the two protruding tenons 140, the effect of fixing the tissue wax block box 400 can be achieved, so that the tissue wax block box 400 is fixed in position in the placement cavity 101, and the bone specimen is kept facing the water flow.

[0042] In another feasible embodiment of the present utility model, since the flushing nozzles (faucets) in the prior art are often arranged corresponding to the sink, the demineralized flushing box for preventing cross-contamination of the present utility model should be placed in the sink during use to facilitate the treatment of the water flow after flushing. At the same time, in order to avoid the box body 100 blocking the flow of the water in the sink, in this embodiment, a plurality of feet 151 are further provided at the bottom of the box body 100, and the bottom plate 130 of the box body 100 is arranged above the plurality of feet 151, so that a hollow structure is formed below the box body 100, which can facilitate the water flow after flushing to flow along the sink and prevent the situation that the water accumulates due to the blockage of the sink by the box body 100.

[0043] In another feasible embodiment of the present utility model, as Figure 1 and Figure 3 shown, when flushing multiple bone specimens, the number of bone specimens may not correspond to the number of the placement cavities 101, which may lead to the ineffective use of the water flow shunted by the cover body 200. To avoid the occurrence of the above problems, in this embodiment, a plurality of switches 230 are further provided on the cover body 200, and the plurality of switches 230 are arranged in one-to-one correspondence with the plurality of diversion holes 210. By operating the switches 230, the opening or closing of the diversion holes 210 can be realized, so that the water flow received by the conduit 220 is shunted into the effective diversion holes 210 to improve the flushing efficiency.

[0044] Specifically, as Figure 1 and Figure 3 shown, in a specific embodiment, the switch 230 is composed of a handle 231 and a ball valve 232. Among them, the handle 231 is rotatably fitted on one side of the cover body 200, specifically on the side corresponding to the conduit 220, so as to facilitate the operation of medical staff, and the rotation range of the handle 231 is 90 degrees; correspondingly, the ball valve 232 is fixedly connected with the handle 231 and can rotate by a corresponding angle following the rotation of the handle 231. The ball valve 232 is fitted in the diversion hole 210, and a valve hole 233 is penetrated through the ball valve 232, and the valve hole 233 is arranged parallel to the corresponding position of the diversion hole 210; as Figure 3 shown, when the switch 230 is opened, as Figure 3 the two ball valves 232 on the upper side, the valve hole 233 is parallel to the diversion hole 210, and at this time, the water flow can continuously flow in the diversion hole 210 along the valve hole 233; when the switch 230 is closed, as Figure 3 the two ball valves 232 on the lower side, the valve hole 233 rotates 90 degrees to be perpendicular to the diversion hole 210, and at this time, the ball valve 232 blocks the diversion hole 210, so that the diversion hole 210 is closed. Through the operation of the above switch 230, the flushing process of a specific placement cavity 101 can be opened or closed to ensure the effectiveness of the water flow use and avoid wasting water resources.

[0045] In the above embodiment, the side of the baffle 110 facing away from the box body 100 is snap-fitted with the inner cavity of the cover body 200, that is, the cover body 200 can be snap-fitted and fixed with the baffle 110 to form a combination with the box body 100 to form an integral body. At the same time, since the installation height of the filter screen 120 corresponds to that of the baffle 110, when the baffle 110 is snap-fitted with the inner cavity of the cover plate, the filter screen 120 is correspondingly sleeved in the inner cavity of the cover body 200, thereby forming a closure above the placement cavity 101. When flushing is performed, it can effectively prevent the bone specimen from being washed out of the placement cavity 101 due to the surging of the water flow.

[0046] In the above embodiment, the connecting pipe 300 further includes a plurality of telescopic portions 310. The arrangement of the telescopic portions 310 is similar to the telescopic structure of a straw in the prior art. During actual use, the length of the connecting pipe 300 can be adjusted through the plurality of telescopic portions 310 to ensure the combination correspondence with the flushing nozzle (water faucet). In addition, the relative angle between the two ends of the connecting pipe 300 can also be adjusted through the telescopic portions 310, further facilitating the combination effect of the connecting pipe 300 and the flushing nozzle (water faucet) by the medical staff.

[0047] Based on the above embodiment, the actual use process of the decalcification flushing box of the present utility model for preventing cross-contamination is as follows:

[0048] First, the medical staff places the box body 100 at a predetermined position in the sink, and places bone specimens (or snap-fits the tissue wax block box 400) in the placement cavity 101 of the box body 100 respectively. Then, the cover body 200 is buckled on the box body 100. One end of the connecting pipe 300 is connected to the conduit 220 on the cover body 200, and the other end is connected to the flushing nozzle (water faucet). Then, a plurality of switches 230 on the cover body 200 are turned on, and finally the flushing nozzle (water faucet) is turned on to flush the bone specimens.

[0049] During the flushing process, the water flow enters the box body 100 and accumulates at the position corresponding to the surrounding plate 150 to submerge the bone specimens. Under the continuous water flow, while flushing the bone specimens, the excess water flows out along the filter screen 120 and flows away along the hollowed-out part of the support feet 151 at the bottom of the box body 100.

[0050] During the process, the water flows after flushing each placement cavity 101 will not intersect in the box body 100, which not only avoids cross-contamination between bone specimens but also improves the flushing efficiency of bone specimens.

[0051] Based on the above embodiments, the present utility model further provides a sample processing instrument, which includes the anti-cross-contamination decalcification flushing box in the above embodiments. The anti-cross-contamination decalcification flushing box includes: a box body, wherein several baffles are arranged inside the box body, and the several baffles divide the inside of the box body into multiple placement cavities; a filter screen is arranged circumferentially on the outer side of the box body, and the height of the filter screen corresponds to that of the baffles; a cover body, wherein multiple diversion holes are arranged inside the cover body, one ends of the multiple diversion holes are arranged corresponding to the multiple placement cavities, and the other ends of the multiple diversion holes are arranged in a penetrating manner with a conduit arranged on the other side of the cover body; a connecting pipe, which is hermetically sleeved and connected with the conduit. By arranging multiple placement cavities inside the box body, isolating the placement cavities through baffles, draining water through the filter screen on the outside, and arranging multiple diversion holes corresponding to the placement cavities on the cover body, and connecting the diversion holes with a flushing nozzle through the connecting pipe, the water flow is divided into multiple strands, so as to achieve the effect of isolating and flushing multiple bone specimens simultaneously, and effectively avoid cross-contamination between bone specimens.

[0052] In summary, the present utility model provides an anti-cross-contamination decalcification flushing box and a sample processing instrument. Among them, the anti-cross-contamination decalcification flushing box includes: a box body, wherein several baffles are arranged inside the box body, and the several baffles divide the inside of the box body into multiple placement cavities; a filter screen is arranged circumferentially on the outer side of the box body, and the height of the filter screen corresponds to that of the baffles; a cover body, wherein multiple diversion holes are arranged inside the cover body, one ends of the multiple diversion holes are arranged corresponding to the multiple placement cavities, and the other ends of the multiple diversion holes are arranged in a penetrating manner with a conduit arranged on the other side of the cover body; a connecting pipe, which is hermetically sleeved and connected with the conduit. By arranging multiple placement cavities inside the box body, isolating the placement cavities through baffles, draining water through the filter screen on the outside, and arranging multiple diversion holes corresponding to the placement cavities on the cover body, and connecting the diversion holes with a flushing nozzle through the connecting pipe, the water flow is divided into multiple strands, so as to achieve the effect of isolating and flushing multiple bone specimens simultaneously, and effectively avoid cross-contamination between bone specimens.

[0053] It should be understood that the application of the present utility model is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description. All such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
