Description

Technical Field

[0001] The present invention relates to the technical field of specimen storage, and in particular to a tumor specimen storage device and a use method thereof. Background Art

[0002] A tumor refers to a new growth formed by the proliferation of local tissue cells under the action of various tumorigenic factors. Because this new growth is mostly space-occupying, block-like protrusions, it is also called a neoplasm. The Department of Oncology will make specimens of different tumors, soak the specimens in specimen bottles filled with formalin solution for storage, in order to facilitate subsequent research and observation.

[0003] The existing method of storing tumor specimens is usually to classify specimen bottles and place them on different placement racks in a storage box. When the specimen bottles need to be taken or stored, the placement rack is pulled out, and then the specimen bottles are taken and placed. The above storage device still has some shortcomings: the placement rack is not provided with a limiting structure for limiting the specimen bottles. When the placement rack is pulled outward, the specimen bottles may not remain stable, so that the specimen bottles are easily displaced or fall from the placement rack, causing damage to the tumor specimens. However, after the limiting structure is set, the limiting structure will block the specimen bottles, making it inconvenient to take and place. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a tumor specimen storage device in view of the above-mentioned defects, which can not only limit the specimen bottle through a limiting structure during the movement of the placement rack to prevent it from displacement or falling, but also the limiting structure will not cause obstruction when taking and placing the specimen bottle, so the taking and placing is more flexible.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: a tumor specimen storage device is provided, comprising a storage box, one side of the storage box is rotatably connected with a sealing door, a plurality of placement racks slidably matched with the storage box are arranged at intervals in the horizontal direction in the storage box, a plurality of support plates for placing specimen bottles are arranged at intervals in the vertical direction on each placement rack, and a limiting component is arranged above each support plate, the limiting component comprises a first limiting part and a second limiting part located on both sides of the placement rack and used to limit the upper part of the specimen bottle, the first limiting part is fixedly connected to the placement rack, the second limiting part is slidably matched with the placement rack in the vertical direction, a guide part with a trajectory from high to low is arranged on the outer side of the first limiting part, a connecting part for slidably matching with the guide part located on the outer side of the first limiting part on the adjacent placement rack is arranged on the outer side of the second limiting part, and when a placement rack is moved outward, the second limiting part located thereon moves down along the trajectory of the guide part to contact with the lower part of the specimen bottle.

[0006] Compared with the prior art, the advantages of this solution are as follows: in the initial state, the bottom of the specimen bottle is located on the support plate, and the upper part of the specimen bottle is limited by the first limiting part and the second limiting part. When a tumor specimen needs to be taken or stored, the placement rack is moved outward. Since the second limiting part is provided with a connecting part for slidingly cooperating with the guide part, and the trajectory of the guide part is from high to low, the second limiting part will gradually move downward in the process of moving the placement rack outward. When the placement rack is moved into place, the second limiting part also moves downward to contact with the lower part of the specimen bottle, which not only exposes one side of the upper part of the specimen bottle and is no longer blocked by the second limiting part, making the operation of taking and storing the specimen bottle more convenient and flexible, but also the specimen bottle is limited by the second limiting part during the whole process to prevent the specimen bottle from being displaced or falling during the movement, causing unnecessary damage to the specimen.

[0007] As a preferred embodiment of the present invention, the first limiting portion includes a first limiting plate and a first clamping block located on the inner side of the first limiting plate, a plurality of first clamping blocks are evenly spaced, and each first clamping block is connected to the first limiting plate by a spring, and the second limiting portion includes a second limiting plate and a second clamping block located on the inner side of the second limiting plate, a plurality of second clamping blocks are evenly spaced, and each second clamping block is connected to the second limiting plate by a spring.

[0008] The benefit of this solution is that multiple specimen bottles are clamped and fixed by the first clamping block and the second clamping block to prevent the specimen bottles from being displaced during the movement of the placement rack. Multiple first clamping blocks and the first limiting plates as well as multiple second clamping blocks and the second limiting plates are all connected by springs, so that the device can adapt to specimen bottles of different sizes and has good adaptability.

[0009] As a preferred embodiment of the present invention, the guide portion includes a first slide groove and a second slide groove which are parallel to and staggered in the length direction of the first limit plate on the outside of the first limit plate, the second slide groove is located below the first slide groove, and a connecting groove for connecting the first slide groove and the second slide groove is also provided on the outside of the first limit plate, the connecting portion includes a slider which is arranged on the outside of the second limit plate and is used to slide with the first slide groove and the second slide groove, and the slider is located on the side of the second limit plate away from the sealing door.

[0010] The benefits of this solution are: (1) When the placement rack is located in the storage box, the slider is located in the first slide groove. When the specimen bottle needs to be taken or stored, the placement rack is moved outward. During this process, the slider first slides along the first slide groove and then gradually moves to the second slide groove located below the first slide groove. When the slider moves from the first slide groove to the second slide groove, the second limit plate also moves downward along the placement rack until the second clamping block contacts the lower part of the specimen bottle. Then the placement rack continues to be moved outward, and the slider slides in the second slide groove until the slider abuts against the side wall of the second slide groove. The second limit part is driven downward by the cooperation of the slider with the first slide groove and the second slide groove, exposing the upper part of the specimen bottle, so that the specimen bottle can be quickly taken out after the placement rack is moved out. (2) The second slide groove is used to limit the movement of the placement rack to prevent the placement rack from being completely moved out of the storage box, thereby avoiding the need for additional manpower and time to install the placement rack back into the storage box.

[0011] As a preferred embodiment of the present invention, the size of the connecting groove is larger than that of the sliding block, the lower part of the connecting groove connected to the first sliding groove is inclined upward, and the lower part of the sliding block away from the sealing door is inclined upward, and the two are inclined to match.

[0012] The benefits of this solution are: (1) The size of the connecting groove is larger than that of the slider, so that the slider can move smoothly from the first slide groove to the second slide groove, thereby driving the second limit portion to move downward, exposing the upper part of the specimen bottle for easy removal; (2) The lower part of the side where the connecting groove is connected to the first slide groove is inclined upward and the slider is inclined to cooperate with the inclined part, so as to ensure that when the specimen bottle is taken out and the placement rack is moved back into the storage box, the slider can slide along the inclined part and move from the second slide groove to the first slide groove, thereby driving the second limiting part to move upward, so that the second limiting part limits the upper part of the specimen bottle.

[0013] As a preferred embodiment of the present invention, the placement rack is provided with a first limiting plate on one side of the front end of which is provided with a groove aligned with and connected to the second sliding groove.

[0014] The benefit of this solution is that when the placement rack moves to its front side and is aligned with the front side wall of the second slide groove, it can still continue to move outward along the groove until the specimen bottle located at the innermost side of the placement rack is exposed, making it easy to take the specimen bottle located at the innermost side of the placement rack. The movement of the placement rack is limited by the abutment between the front side of the placement rack and the side wall of the groove, avoiding the placement rack from being completely moved out when moving outward.

[0015] As a preferred embodiment of the present invention, the placement rack is provided with a through groove at the rear end of one side of the first limiting plate, which is aligned with and connected to the first sliding groove.

[0016] The benefit of this solution is that: when the placement rack is moved outward, the slider on the adjacent placement rack on one side slides in cooperation with the guide portion on the placement rack, and the slider on the placement rack slides in cooperation with the guide portion on the adjacent placement rack on the other side, and a through groove aligned with and connected to the first slide groove is provided at the rear end of one side of the placement rack provided with the first limit plate, so that when a certain placement rack is moved outward, the placement rack connected to the guide portion on the placement rack through the slider is prevented from moving outward together, thereby avoiding unnecessary movement.

[0017] As a preferred embodiment of the present invention, a plurality of through holes are arranged at intervals on the second limiting plate along its length direction, a pull rod is fixedly connected to the outer side of each second clamping block, the pull rod passes through the through hole, and the spring is sleeved on the pull rod.

[0018] The benefits of this solution are: (1) After the placement rack moves outward and into position and the second limit portion is located at the bottom of the specimen bottle, the pull rod is pulled. At this time, the spring is compressed, and the inner side of the second clamping block no longer contacts the specimen bottle, so the specimen bottle can be removed relatively easily. After removing the specimen bottle, release your hand, and the pull rod returns to its initial position driven by the spring, so that the movement of the placement rack will not be blocked when the placement rack is moved back to the storage box; (2) The pull rod is separately arranged on the outside of each second clamping block. When a specimen bottle needs to be taken, it is pulled open, and the limit on the specimen bottle is cancelled and the specimen bottle is taken away. Other specimen bottles that do not need to be taken are still limited by the second clamping block. The operation is simple and targeted.

[0019] As a preferred embodiment of the present invention, along the length direction of the storage box, one side inside the storage box is provided with multiple groups of third slide grooves and fourth slide grooves in the vertical direction corresponding to the positions of the first slide groove and the second slide groove respectively, the third slide groove and the fourth slide groove are connected by a connecting groove, and the lower part of the side where the connecting groove is connected to the third slide groove is inclined upward.

[0020] The benefit of this solution lies in that a first limit plate and a second limit plate are respectively provided on both sides of the placement rack at the end position, the guide portion on the first limit plate is used to slidably cooperate with the connecting portion on the adjacent placement rack, the second limit plate is close to the side wall of the storage box, and the slider on the second limit plate slidably cooperates with the third slide groove and the fourth slide groove located on the side wall of the storage box. When the placement rack is moved outward, the second limit portion is driven downward by the cooperation of the slider, the third slide groove and the fourth slide groove, exposing the upper part of the specimen bottle, which is convenient for taking the specimen bottle on the placement rack at the end position.

[0021] As a preferred embodiment of the present invention, the first clamping block and the second clamping block are both arc-shaped, and the inner sides of the first clamping block and the second clamping block are both provided with soft material.

[0022] The benefit of this solution is that the first clamping block and the second clamping block are designed to be arc-shaped, which can match the outer edge of the specimen bottle, clamping the specimen bottle more stably and closely, and the inner sides thereof are provided with soft material, making the specimen bottle safer during the clamping and fixing process.

[0023] As a preferred embodiment of the present invention, Step 1: Open the sealed door on one side of the storage box and move the rack where the specimen bottle to be taken or placed is located outward; Step 2: After the placement rack moves to the front side of the slider and abuts against the front side wall of the groove on the adjacent placement rack, pull the pull rod at the specific position where the specimen bottle to be taken or placed is located, take out or put in the specimen bottle, and then release the pull rod; Step 3: Move the shelf back into the storage box and close the sealed door.

[0041] The method of using the tumor specimen storage device of the present invention is as follows: Step 1: Open the sealed door 10 on one side of the storage box 1, and move the placement rack 2 where the specimen bottle to be taken or placed is located outward; Step 2: After the placement rack 2 moves to the front side of the slider 7 and abuts against the front side wall of the groove 203 on the adjacent placement rack 2, pull the pull rod 8 at the specific position where the specimen bottle to be taken or placed is located, take out or put in the specimen bottle, and then release the pull rod 8; Step 3: Move the placement rack 2 back into the storage box 1 and close the sealing door 10.

[0042] Specific use process: In the initial state, the bottom of the specimen bottle is located on the support plate 201, and the upper part of the specimen bottle is limited by the first limiting part and the second limiting part. When the specimen bottle needs to be taken or stored, the sealed door 10 on one side of the storage box 1 is opened, and the handle 11 on the front side of the placement rack 2 is held, and the placement rack 2 where the specimen bottle to be taken or stored is located is pulled out along the fifth slide groove 101. In the process of moving the placement rack 2 outward, the slider 7 located on the outside of the second limiting plate 5 first slides along the first slide groove 301, and then moves through the connecting groove 303 to the second slide groove 302 located below the first slide groove 301. When the slider 7 moves from the first slide groove 301 to the second slide groove 302, the second limiting plate 5 also Move downward along the placement rack 2 so that the second clamping block 6 contacts the lower part of the specimen bottle, and then continue to move the placement rack 2 outward, the slider 7 slides along the second slide groove 302, and transitions from the second slide groove 302 to the groove 203 on the placement rack 2 aligned with the second slide groove 302, until the slider 7 abuts against the side wall of the groove 203, at this time, the rear side of the limiting strip 102 located in the middle of the front side of the fifth slide groove 101 abuts against the rear side wall of the limiting groove 202 located at the top of the placement rack 2, and the cooperation of the slider 7 with the first slide groove 301 and the second slide groove 302 drives the second limiting plate 5 and the second clamping block 6 to move down to contact the lower part of the specimen bottle, exposing the upper part of the specimen bottle, so as to facilitate the taking and placing of the specimen bottle.

[0043] After the placement rack 2 moves outward into position and the second limiting plate 5 and the second clamping block 6 are located at the lower part of the specimen bottle, the pull rod 8 is pulled in the direction away from the first clamping block 4. At this time, the spring 9 is compressed, and the inner side of the second clamping block 6 no longer contacts the specimen bottle.
