Description

Technical Field

[0001] The invention relates to the technical field of test tube boxes, and in particular to a freezing tube storage and access detection device. Background Art

[0002] In many fields such as biomedical research, clinical testing, and cell therapy, cryotubes are needed to freeze biological samples at low temperatures to maintain the activity and biological properties of the samples. Multiple cryotubes are stored in a test tube box.

[0003] With the continuous expansion of the scale of biological sample banks and the increasing number of experimental samples, the orderly management and precise positioning of test tubes in test tube boxes have become important issues that need to be urgently addressed. At present, conventional test tube boxes lack effective positioning devices during use, and can only rely on label identification to record the information of test tubes. Sampling requires repeated picking, which is time-consuming, and the labels are easily damaged or contaminated, making them difficult to identify, increasing the difficulty of quickly picking up the corresponding cryopreserved tubes. Some complex experiments or clinical applications require rapid screening and extraction of specific batches or types of samples. For example, in emergency cell therapy applications, quickly locating the required cell sample tubes is crucial to the treatment of patients, and traditional test tube boxes are difficult to achieve this.

[0004] In summary, we consider designing a device that can detect and locate the storage position of each cryotube on a test tube box so that the corresponding cryotube sample can be accurately and effectively selected; in view of this, we propose a cryotube storage and retrieval detection device. Summary of the invention

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0047] See also Figure 1-Figure 13 The present invention describes the above technical solution in detail through the following embodiments:

[0048] The cryotube access detection device of this embodiment includes: Figure 2 The barcode scanner 5 shown in the figure, after using the cryotube 1 to take samples, a label will be attached to the tube body, and the label records the sample information, and the barcode scanner 5 quickly scans and enters the cryotube 1 information into the background system. This part belongs to the existing mature application technology, so it will not be explained in detail; it also includes:

[0049] Test tube box 2, such as Figure 4-Figure 10As shown in the structure, the test tube box 2 of this embodiment includes a box body 21 with a 6×10 specification plug hole 201, and a packaging bottom plate 22 installed at the bottom of the box body 21; the packaging bottom plate 22 is provided with a top hole 221 coaxially arranged corresponding to the plug hole 201, and the packaging bottom plate 22 is provided with side protrusions 222 at both ends of the packaging installation cavity 202, and a shaft 23 is installed between the side protrusions 222 at both ends; It should be noted that in order to accurately and effectively detect whether the cryopreservation tube 1 is effectively inserted into the plug hole 201 or is lifted up in the plug hole 201, the present embodiment is as follows Figure 8-Figure 10 In the structure shown, a mounting cavity 202 is provided between the box body 21 and the packaging bottom plate 22 , and a lever unit 24 corresponding to the position of the plug hole 201 is installed in the mounting cavity 202 .

[0050] Specifically, Fig. 9 As shown in the structure, in this embodiment, the lever unit 24 includes a baffle 241 and a connecting plate 242 connected by a rotating seat 243, and the rotating seat 243 is coaxially rotatably mounted on the shaft 23, as shown in FIG. Figure 8 and Fig. 9 In the structure shown, a hammer head 244 is installed at the outer end of the connecting plate 242, and an obtuse angle with the opening facing upward is formed between the baffle 241 and the connecting plate 242; that is, when the freezing tube 1 is not effectively inserted into the socket 201 at the corresponding position, the lever unit 24 will rotate along the shaft 23 as a whole due to the deadweight of the hammer head 244, and keep the baffle 241 in the state of tilting upward at the socket 201; conversely, when the freezing tube 1 is accurately and effectively inserted into the socket 201, the freezing tube 1 will press down the baffle 241, so that the lever unit 24 as a whole overcomes the deadweight of the hammer head 244, so that the hammer head 244 rotates along the shaft 23 and tilts up.

[0051] It should be explained that the lever unit 24 is provided to effectively monitor whether the cryopreservation tube 1 is effectively inserted or ejected; therefore, a signal corresponding to the action needs to be detected, and a signal source needs to be provided. In this embodiment, a conductive metal sheet is provided on the bottom surface of the baffle 241. Figure 8 and Fig. 9 In the horizontal compression state shown, a circuit-breaking electrode sheet corresponding to the conductive metal sheet is provided on the packaging bottom plate 22. The circuit-breaking electrode sheet is two disconnected conductive electrode sheets. When the conductive metal sheet and the two disconnected conductive electrode sheets are in contact, an electrically connected closed loop can be formed. In order to effectively detect the insertion information of the cryogenic tubes 1 at various positions, the structure of the multiple lever units 24 connected to the closed loop in this embodiment adopts parallel electrical connection, so that the information of whether each cryogenic tube 1 is inserted or lifted can be output independently.

[0052] In order to realize the automatic ejection of the specific cryopreservation tube 1, the present embodiment is provided with a storage stand 3, such as Figure 11-Figure 12The structure shown includes a carrying bin 31 for carrying a test tube box 2, a support plate 32 is installed in the carrying bin 31, and the carrying bin 31 is located on the upper and lower sides of the support plate 32, respectively, and a support cavity 301 and a drive cavity 302 are provided, and the test tube box 2 is inserted in the support cavity 301; a through hole 321 corresponding to the position of the top hole 221 is provided on the support plate 32, and a plurality of cylinders 35 are installed in the drive cavity 302. After the output shaft of the cylinder 35 is ejected, it will pass through the through hole 321 to eject the cryogenic tube 1 upward. At this time, the lever unit 24 will be reset under the action of the hammer head 244, and the local electrical connection will be disconnected. The corresponding cryogenic tube 1 is effectively ejected to detect and judge. To accurately eject the specific cryogenic tube 1, it is necessary to record the process of inserting the specific position after the barcode scanning gun 5 enters the information during sampling, so that it can be accurately ejected when the corresponding sample needs to be taken out.

[0053] In this embodiment, a vertical support plate 33 is installed on the carrier bin 31. The vertical support plate 33 is detachably installed with a detection top plate 4 through a connecting block 34. A proximity switch corresponding to the position of the jack 201 is installed at the bottom of the detection top plate 4. The proximity switch can sense whether there is a cryogenic tube 1 at the corresponding position, which is a judgment condition for the withdrawal of the output shaft of the cylinder 35. The distance signal changes after the cryogenic tube 1 is placed, lifted or removed, which can be used as a verification structure to judge whether the cryogenic tube 1 is effectively placed, ejected or removed, thereby providing accuracy guarantee. In this embodiment, the cylinder 35 adopts a MAL16×25 mini cylinder, and the proximity switch adopts a LJ18A3-8-Z / BX inductive proximity switch, which has low cost and compact structure.

[0054] The cryopreservation tube access detection device has the following working principle: first, according to the needs of batch sample preparation, an information label is attached to the cryopreservation tube 1 during sampling, and the information is entered through the barcode scanner 5 before being placed in the test tube box 2, and the device is inserted into the jack 201; after insertion, the lever unit 24 at the corresponding position is pressed down to form a closed loop to release an electrical signal to the background, and the position information of the cryopreservation tube 1 with the signal label is recorded and obtained at this time, and the above steps are repeated to complete the sample preparation and storage process;

[0055] During use, when it is necessary to take out a single cryogenic tube 1 sample, the background system starts the mini cylinder at the corresponding position to push out the cryogenic tube 1 in sequence according to the required sample. At this time, the lever unit 24 is disconnected, and the electrical signal is lost to verify whether the ejection action is effective; at this time, the inductive proximity switch detects that the cryogenic tube 1 is lifted up but not taken out. After it is taken out, the inductive proximity switch signal is lost and returns to normal; when it is necessary to take out multiple cryogenic tubes 1 samples in batches, multiple cryogenic tubes 1 can be lifted up at one time. In this embodiment, a signal light is installed at the socket 201 of the test tube box 2. When it is needed When taking out the corresponding cryogenic tube 1, the corresponding signal light flashes, and the bottom lever unit 24 is disconnected after the cryogenic tube 1 is taken out, and the inductive proximity switch is used to verify whether the corresponding cryogenic tube 1 is taken out correctly; when multiple cryogenic tubes 1 are taken out and used, they need to be reset and put into the corresponding socket 201 again, and the barcode scanning gun 5 reads the corresponding position information after scanning the code. At this time, the signal light at the corresponding position socket 201 flashes, which is convenient for quickly inserting the corresponding cryogenic tube 1 for storage. Other embodiments can be equipped with a voice broadcast to quickly broadcast whether the corresponding position is accurately placed;

[0056] Repeating the above steps can efficiently complete the storage and retrieval of cryogenic tubes, and can detect the storage and access information of cryogenic tubes in real time without the need to manually search for corresponding cryogenic tubes. It has high accuracy and efficiency, and is of great significance for the combination of batch detection and information equipment. The above system control part belongs to the application of existing control programs, so no further explanation will be given.

If the specific posture changes, the directional indication will also change accordingly.
