Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, in particular to a sample storage device. Background Art

[0002] In medical tests, correct test results are of great significance to the diagnosis, treatment and prognosis of diseases, and correct test results are closely related to the collected samples. The method of sample collection is determined by the complexity of sample collection. Some samples are completed by clinical medical staff, such as bone marrow puncture collection by doctors, blood puncture collection by nurses, or ascites puncture fluid collection and cerebrospinal fluid collection, all of which are completed by professionals. Another part of the samples are collected with the cooperation of patients, such as urine collection, urine samples collected during routine urine tests. When doing routine stool tests, fecal samples are collected, and sputum samples for bacterial culture are collected. Patients are required to cooperate in collecting sputum samples deep in the throat according to requirements. In addition, according to the requirements of the patient's doctor, special sample collection is required, which requires the cooperation of clinical doctors and patients, such as puncture fluid collection and sterile body fluid collection, as well as 24-hour urine sample collection.

[0003] Most of the time, samples cannot be analyzed immediately after collection, or they need to be retested after analysis. Samples need to be preserved in time, and most samples need to be stored under low temperature conditions. Therefore, the collected samples should be stored immediately as required, labeled with appropriate labels, and the storage status and location of the samples should be recorded to ensure the quality of the samples. The existing sample refrigeration device opens the sample box as a whole when medical staff store and retrieve samples. The sample box exchanges heat with the air, resulting in a large temperature difference inside the sample box, which affects other samples in the sample box. Therefore, it is necessary to propose a new sample storage device. Utility Model Content

[0004] In order to solve the problem that when medical staff open the sample box as a whole to store samples, the sample box produces heat exchange with the air, resulting in a large temperature difference inside the sample box, which affects other samples in the sample box, the purpose of the utility model is to provide a sample storage device that reduces the temperature difference inside the sample box when the sample box is opened.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a sample storage device, comprising a storage box and a plurality of sample boxes, wherein the storage box is provided with a plurality of partition plates to divide the interior of the storage box into a plurality of partition chambers, the sample boxes are respectively located in the partition chambers, a slide groove is provided at the connection between the partition plates near the center of the storage box, a connecting rod is provided in the slide groove, an arrow for indicating the direction is fixedly connected above the connecting rod, the connecting rod extends to the bottom of the storage box and vertically slides with the slide groove, a fixing component for fixing the position of the connecting rod is provided in the connecting rod, a plurality of card blocks are provided at the lower part of the connecting rod, the direction of the card blocks is the same as the direction of the arrow, a plurality of slots for inserting sample test tubes are provided in the sample boxes, a plurality of grooves corresponding to the card blocks are provided at the lower part of the sample boxes, and a cooling component is provided in the sample boxes.

[0006] The principle of the basic solution is: the storage box is divided into several partition chambers with partitions, and each partition chamber is equipped with a sample box for placing samples. When medical staff need to store or retrieve samples, they rotate the connecting rod so that the arrow points to the chamber where the sample needs to be stored or retrieved. The card block is embedded in the groove of the sample box in the corresponding chamber, the cover of the corresponding chamber is opened, the connecting rod is lifted upward, and the sample box moves upward with the connecting rod until the connecting rod fixing block pops out, the connecting rod is released, and the fixing block fixes the connecting rod and the sample box on the partition. After storing or retrieving the sample, press the fixing block into the connecting rod to retract it into the fixing groove, press the connecting rod downward, and finally close the cover to start cooling.

[0007] The beneficial effects of the basic scheme are: 1. Compared with the prior art, the prior art opens the entire cover of the sample box when storing and accessing samples, causing a large temperature difference inside the sample box, which is likely to have an adverse effect on other samples. This example can open the chambers that need to be accessed in sections, reduce the overall temperature difference of the sample box, and reduce the adverse effects on other samples.

[0008] 2. When the connecting rod is lifted, the sample box rises together with the connecting rod. When storing and retrieving samples, medical staff do not need to put their hands into the storage box. The samples can be placed directly in the sample box, which is convenient for medical staff to perform storage and retrieval operations.

[0009] Furthermore, each of the partition chambers is provided with a cover plate, one side of the cover plate is hinged to the outer wall of the storage box, and a handle is fixedly connected to the cover plate.

[0010] The beneficial effects of the basic solution are: the handle can open the cover more conveniently, and a cover is separately provided on the partition cavity, so that when the storage box opening is opened, the cover can be opened separately, thereby reducing the opening area of ​​the storage box, reducing the area of ​​heat exchange between the cold air and the air at the opening of the storage box, and reducing the temperature change inside the storage box.

[0011] Furthermore, a heat-insulating layer is provided inside the storage box, and the cover plates are all transparent cover plates.

[0012] The beneficial effects of the basic solution are: the insulation layer can ensure that the temperature inside the storage box will not be lost, and the transparent cover can facilitate observation of the information on the top of the sample, making it convenient for medical staff to confirm the location of the sample and accurately find the sample area when taking the sample.

[0013] Furthermore, a plurality of first elastic members are fixedly connected to the bottom end of the sample box, and the other ends of the plurality of first elastic members are fixedly connected to the storage box.

[0014] The beneficial effect of the basic solution is that the first elastic member can play a buffering role when the sample box moves downward to the bottom of the storage box, and can also play a shock-absorbing and protective role for the sample box when the storage box is moved, thereby reducing the possibility of sample damage.

[0015] Furthermore, the fixing assembly includes a second elastic member, a fixing block and a fixing groove formed on the connecting rod, one end of the second elastic member is fixedly connected to the fixing groove, and the other end of the second elastic member is fixedly connected to the fixing block.

[0016] The beneficial effect of the basic solution is that when the connecting rod rises to a certain position, the fixed block pops out so that the fixed block can be stuck on the partition. At this time, the sample box can be fixed in a position close to the upper end of the partition, making it convenient for medical staff to store and retrieve samples.

[0017] Furthermore, the cooling assembly includes a cooler, a hose and a plurality of cooling pipes. The cooler is connected to the hose. The hose is laid at the bottom of the storage box and extends into the sample box. The cooling pipes are evenly and horizontally arranged in the sample box and connected to the hose. The cooling pipes can contact the sample test tubes.

[0018] The beneficial effect of the basic scheme is that the uniformly arranged cooling tubes can simultaneously start to reduce the temperature of the upper and lower ends of the sample tubes when cooling, reducing the upper and lower temperature difference of the sample when cooling, thereby reducing the adverse effects on the sample.

[0019] Furthermore, one side of the storage box is connected to a liquid valve, and the liquid valve is connected to a hose.

[0020] The beneficial effect of the basic solution is that the cooler is arranged outside the storage box, the space is relatively open, and the difficulty of repairing the cooler when a failure occurs is reduced.

[0021] Furthermore, a sponge layer is fixedly connected to the bottom end of the slot.

[0022] The beneficial effect of the basic solution is that the sponge layer can reduce the squeezing force between the bottom end of the sample test tube and the slot when the sample test tube is inserted into the slot, thereby reducing the possibility of damage to the sample test tube.

The second elastic member 503 is welded to one end of the fixing groove, and the other end of the second elastic member 503 is welded to the fixing block 502.

[0030] The sample box 2 is provided with a plurality of slots 6 for inserting sample test tubes. The bottom of the slots 6 is fixedly connected with a sponge layer. The sponge layer can reduce the squeezing force between the bottom of the sample test tube and the slots 6 when the sample test tube is inserted into the slots 6, thereby reducing the possibility of damage to the sample test tube. The lower part of the sample box 2 is provided with a plurality of grooves corresponding to the card blocks 501. When the connecting rod 5 rotates and the pointer points to the sample box 2, the card blocks 501 are embedded in the grooves, so that the sample box 2 can slide up and down with the connecting rod 5. The sample box 2 is provided with a cooling assembly, which includes a cooler, a hose 11 and a plurality of cooling tubes 10. The cooler and The hose 11 is connected, and the hose 11 is laid at the bottom of the storage box 1 and extends into the sample box 2. The cooling tube 10 is evenly and horizontally arranged in the sample box 2 and is connected to the hose 11. The cooling tube 10 is in contact with the sample test tube. The evenly arranged cooling tube 10 can start to reduce the temperature of the upper and lower ends of the sample test tube at the same time when cooling, reducing the temperature difference between the upper and lower ends of the sample when cooling, thereby reducing the adverse effects on the sample. A liquid valve 12 is connected to one side of the storage box 1, and the liquid valve is connected to the hose 11. The cooler is arranged outside the storage box 1, and the space is relatively open, which reduces the difficulty of repairing the cooler when a failure occurs.

[0031] The utility model uses a method of using a partition plate 3 to divide a storage box 1 into several partition chambers 4, and each partition chamber 4 is provided with a sample box 2 for placing samples. When the medical staff needs to store the sample, the connecting rod 5 is rotated to make the arrow point to the chamber where the sample needs to be stored, and the card block 501 and the groove of the sample box 2 of the corresponding chamber are embedded together, so that the sample box 2 can slide up and down with the connecting rod 5, and the handle 701 of the corresponding chamber is pulled to open the cover 7, and the connecting rod 5 is lifted upward to make the sample box 2 move upward with the connecting rod 5 until the second elastic component 503 stretches and pushes the fixing block 502, and the fixing block 502 pops out. At this time, the connecting rod 5 can be loosened, and the fixing block 502 can fix the connecting rod 5 and the sample box 2 on the partition plate 3.
