Abstract
Description
Technical Field
[0001] This utility model relates to the field of tissue specimen collection, specifically a tissue specimen collection and low-temperature transport device. Background Technology
[0002] In medical scientific research, clinical specimen collection and sampling are crucial links in supporting experimental data. Especially during the process of transporting samples from hospitals to laboratories, it is worth considering how to improve collection efficiency and reduce tissue sample damage. Currently, the tissue sampling required by laboratories usually involves collecting tissue specimens removed from patients during surgery, or collecting samples after constructing experimental animal models. In laboratory samples involving tumor tissue, it is usually necessary to collect tumor tissue, adjacent tissue, and normal tissue, and even to sample based on specific distances.
[0003] Traditional sampling methods involve using forceps to grasp the sample and cutting with scissors or a blade. Repeated grasping and cutting can damage tissue samples, affecting the accuracy of experimental results, especially in some microscopic observational studies. Furthermore, repeated cutting and clamping of the original specimen can also affect pathological diagnosis. After collection, the traditional method involves placing the sample into a specimen tube or tissue bag and then transporting it in a transport box equipped with ice packs. These transport boxes often have inconsistent cooling effects, and placing multiple samples in one transport box and temporarily labeling them can lead to sample confusion.
[0004] Existing devices have multiple mounting slots and multiple blades that may increase the risk of injury to sampling personnel. Furthermore, after sampling, additional specimen bottles or bags are needed to separate the specimens, and the tissue may still need to be picked up with tweezers during separation, which may cause tissue damage. Therefore, a tissue specimen collection and cryogenic transport device needs to be designed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a tissue specimen collection and low-temperature transport device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a tissue specimen collection and low-temperature transport device, comprising a placement box and multiple collection tubes, wherein the placement box has multiple fixed cavities on its inner side for placing the collection tubes in a rectangular arrangement, and a collection component for collecting tissue specimens is screwed onto the inner side of the collection tubes; the placement box has an insulation cavity on its inner side for holding cryogenic fluid, and an insulation component for heat insulation is embedded in the inner side of the insulation cavity.
[0007] Preferably, the collecting component includes a collecting tube screwed to the inside of the collecting tube and near the top, a stress cap being fitted and screwed to the outside of the collecting tube, a booster being slidably connected through the top of the collecting tube, a piston block being fixedly connected to the bottom of the booster, and a fixedly installed cutting ring blade being embedded in the bottom of the collecting tube.
[0008] Preferably, the insulation component includes an insulation sleeve embedded in the inner wall of the insulation cavity, an insulation board is fixedly placed inside the insulation sleeve, an insulation cotton board is placed on one side of the insulation board, and the inner side of the insulation sleeve is filled with insulation material.
[0009] Preferably, the placement box has multiple evenly arranged card slots around its perimeter, which are used to place specimen information cards.
[0010] Preferably, the inner sidewall of the fixed cavity is fixedly connected with a plurality of fixed rings arranged in a rectangular pattern.
[0011] Preferably, a limiting ring is formed inside the collection tube and near the bottom.
[0012] Preferably, a pressure relief hole is provided on one side of the collection tube.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Multiple fixed cavities can accommodate multiple collection tubes. The collection element screwed to the top of the collection tube can be used to circumferentially extract tissue specimens, which are then collected and stored through the collection tubes. The cryoprotectant in the insulation cavity inside the placement box can preserve the specimen samples in the fixed cavities at low temperatures. The insulation element fixed inside the insulation cavity can isolate external heat, extending the duration of heat insulation and preservation of the samples. This allows the placement box to transfer the collected samples to other testing laboratories for use after collection.
[0015] 2. When collecting specimens, unscrew the specimen collection tube, and press down on the corresponding tissue using the cutting ring at the bottom of the tube to collect the specimen. The cutting ring at the bottom of the tube will cut the tissue. After collection, tighten the specimen collection tube. The collection tube and stress cap are screwed to the top and bottom of the collection tube respectively. Place the collection tube in the frozen specimen box. After the specimen arrives at the laboratory, unscrew the stress cap and specimen collection tube, and use the pusher to push the tissue out of the specimen collection device. This reduces tissue handling, minimizes tissue damage, ensures that the collected specimens are of similar size, improves research accuracy, and facilitates observation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please refer to Figure 1-5 As shown, this utility model provides a tissue specimen collection and low-temperature transport device, including a placement box 1 and multiple collection tubes 2. The placement box 1 has multiple fixed cavities 3 arranged in a rectangular pattern for placing the collection tubes 2. Collection components for tissue specimen collection are screwed onto the inside of the collection tubes 2. The placement box 1 has an insulation cavity 4 for holding cryogenic fluid. Insulation components for heat insulation are embedded in the inside of the insulation cavity 4. Multiple fixed rings 15 arranged in a rectangular pattern are fixedly connected to the inner wall of the fixed cavity 3.
[0025] In addition, multiple fixing cavities 3 can accommodate multiple collection tubes 2. Multiple fixing rings 15 inside the fixing cavities 3 limit and fix the collection tubes 2 to prevent them from shifting or shaking. The collection element screwed to the top of the collection tube 2 can be used to circumferentially cut and extract the tissue specimen, which is then collected and stored through the collection tube 2. The cryoprotectant in the insulation cavity 4 inside the placement box 1 can preserve the specimen sample in the fixing cavity 3 at low temperature. The insulation element fixed inside the insulation cavity 4 can isolate external heat and extend the time that the insulation element can keep the sample warm, so that the placement box 1 can transfer the sample to other testing laboratories after collection through the collection tube 2.
[0026] Specifically, the collection component includes a collection tube 5 screwed to the inside of the collection tube 2 near the top, a stress cap 6 fitted and screwed to the outside of the collection tube 5, a booster 8 slidably connected through the top of the collection tube 5, a piston block 9 fixedly connected to the bottom of the booster 8, a fixedly installed cutting ring blade 10 embedded in the bottom of the collection tube 5, a limit ring 16 integrally formed on the inside of the collection tube 5 near the bottom, and a pressure relief hole 17 opened on one side of the collection tube 5.
[0027] During specimen collection, the specimen collection tube 2 is unscrewed, and the cutting ring 10 at the bottom of the collection tube 5 is used to press down on the corresponding tissue for collection. The cutting ring 10 at the bottom of the collection tube 5 cuts the tissue. After collection, the specimen collection tube 2 is tightened. The collection tube 2 and the stress cap 6 are screwed to the upper and lower sides of the collection tube 5 respectively. The collection tube 2 is placed in the frozen specimen placement box 1. After the specimen arrives at the laboratory, the stress cap 6 and the specimen collection tube 2 are unscrewed, and the tissue is pushed out of the specimen collection device with the help of the pusher 8. This can reduce tissue clamping, reduce tissue damage, and ensure that the collected specimens are of similar size, thereby improving the accuracy of research and facilitating observation.
[0028] Furthermore, the pressure relief hole 17 facilitates gas discharge and allows the booster 8 to move upward within the collection tube 5. After the cutting ring blade 10 cuts the tissue, the limiting ring 16 can squeeze the tissue to prevent the sample tissue from moving downward and falling off.
[0029] More specifically, the insulation component includes an insulation sleeve 11 embedded in the inner wall of the insulation cavity 4, an insulation board 12 fixedly placed inside the insulation sleeve 11, an insulation cotton board 13 placed on one side of the insulation board 12, and insulation material filling the inner side of the insulation sleeve 11.
[0030] It should be added that the insulation sleeve 11 is a rectangular ring shape, and the insulation sleeve 11 wraps around the outside of multiple fixed cavities 3. The heat insulation plate 12 inside the insulation sleeve 11 can insulate against external heat, and the heat insulation cotton board 13 can insulate against the coolant, thereby improving the heat preservation effect of the insulation sleeve 11 and the coolant on the sample.
[0031] Furthermore, the placement box 1 has multiple evenly arranged card slots 14 around its four sides. The card slots 14 are used to place specimen information cards. There are specimen information marking card slots 14 on the front, back, left and right walls, where cards can be inserted to mark specimen information.
[0032] Working principle: First, when collecting a specimen, rotate the collection tube 2 and stress cap 6 to separate them from the collection tube 5. Using the cutting ring 10 at the bottom of the collection tube 5, press one side of it against the corresponding tissue to collect the specimen. The limiting ring 16 squeezes the tissue to prevent the sample from moving downward. After collection, tighten the specimen collection tube 2 and stress cap 6, and place the specimen collection tube 5 and collection tube 2 into the box 1. Multiple fixing rings 15 in the fixing cavity 3 limit and fix the collection tube 2 and stress cap 6. After the specimen arrives at the laboratory, unscrew the stress cap 6 and specimen collection tube 2, and use the pusher 8 to push the tissue out of the specimen collection device.
