Description

Technical Field

[0001] This utility model relates to the field of blood collection tube storage technology, and in particular to a blood collection tube storage device. Background Technology

[0002] Blood collection tubes are essential medical devices used in clinical medicine for collecting, preserving, and transporting blood samples. They are typically composed of transparent or semi-transparent plastic tubing, rubber stoppers, and additives. Modern blood collection tubes utilize a vacuum negative pressure design for quantitative blood collection, and their purpose can be distinguished by the color of the cap, facilitating clinical operation. Their materials must meet requirements for biocompatibility, pressure resistance, and sealing to ensure the integrity of samples during storage and transportation. Blood collection tubes are widely used in medical testing fields such as biochemical analysis, complete blood count, and immunoassay, and are one of the fundamental tools for laboratory diagnostics. In the field of small-scale storage devices, to ensure sufficient storage capacity, multiple layers of tube racks are usually installed in the storage container (e.g., storage box) for stacking blood collection tubes. However, this method has a drawback: accessing the lower layer of tube rack requires removing the upper layer first, which is cumbersome. Therefore, there is an urgent need for a storage device that can store blood collection tubes in layers to ensure sufficient storage capacity while facilitating easy access. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a blood collection tube storage device that can store blood collection tubes in layers and facilitates convenient storage and retrieval.

[0004] The blood collection tube storage device according to an embodiment of the present invention includes:

[0005] A base, wherein the base is provided with a vertically extending mounting shaft;

[0006] Multiple storage sections are arranged vertically at intervals and abutting each other in sequence. Each storage section includes a rotating cylinder and two storage boxes. The rotating cylinder is coaxially sleeved on the mounting shaft. The two storage boxes are respectively connected to opposite sides of the rotating cylinder in the radial direction. The top of each storage box is open.

[0007] In each pair of adjacent storage sections, one of them can rotate circumferentially relative to the other along the mounting axis, such that the two adjacent storage sections are vertically aligned, or that the storage boxes of the two adjacent storage sections are offset circumferentially along the rotating cylinder.

[0008] The blood collection tube storage device according to the embodiments of this utility model has at least the following beneficial effects:

[0009] This embodiment can store blood collection tubes in multiple storage sections. When storing or retrieving blood collection tubes in any storage section other than the topmost one, one of these sections and the one above it can be rotated circumferentially relative to the other along the mounting axis. This causes the storage boxes of the two sections to be offset radially along the rotating cylinder, thus exposing the opening at the top of the storage box of the section. The operator can then store or retrieve blood collection tubes from the storage box of the section without having to remove the other storage sections above it, making the storage and retrieval operation very convenient. In addition, since each storage section has two storage boxes, which are respectively connected to opposite sides of the rotating cylinder radially, the offset of the center of gravity of the storage section relative to the central axis of the mounting shaft can be reduced during the rotation of the storage section, preventing the device from tipping over and ensuring high structural stability.

[0020] According to some embodiments of the present invention, the mounting part is defined with a mounting cavity, the mounting cavity is opened on the side near the locking hole, and when the limiting part abuts against the end of the mounting part away from the locking hole, the boss and the compression spring are both located in the mounting cavity.

[0021] According to some embodiments of the present invention, a first positioning structure is provided on the base. The first positioning structure is used to cooperate with the lowermost storage part to restrict the rotation of the lowermost storage part relative to the mounting shaft.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0041] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0042] Reference Figure 1 , Figure 2 and Figure 4 As shown, a blood collection tube storage device according to an embodiment of the present invention includes a base 100 and a storage part 200.

[0043] The base 100 is provided with a vertically extending mounting shaft 110.

[0044] Multiple storage sections 200 are provided, arranged vertically at intervals and abutting each other in sequence. Each storage section 200 includes a rotating cylinder 210 and two storage boxes 220. The rotating cylinder 210 is coaxially sleeved on the mounting shaft 110. The inner hole of the rotating cylinder 210 is a cylindrical hole, that is, when there is no circumferential limit, the storage section 200 can rotate relative to the mounting shaft 110 around the central axis of the mounting shaft 110 through the rotating cylinder 210. The two storage boxes 220 are respectively connected to opposite sides of the rotating cylinder 210 in the radial direction. The top of the storage box 220 is open. The storage box 220 is used to store blood collection tubes. It should be noted that when the blood collection tubes are stored in the storage box 220, the top of the blood collection tubes is lower than the top of the storage box 220.

[0045] In each pair of adjacent storage sections 200, one can rotate circumferentially relative to the other along the mounting shaft 110, either vertically aligning the two adjacent storage sections 200 or offsetting the storage boxes 220 of the two adjacent storage sections 200 circumferentially along the rotating cylinder 210. Clearly, when the two adjacent storage sections 200 are vertically aligned, the storage box 220 of the lower storage section 200 is closed by the upper storage section 200. When the storage boxes 220 of the two adjacent storage sections 200 are offset circumferentially along the rotating cylinder 210, the opening at the top of the storage box 220 of the lower storage section 200 is exposed, allowing the operator to access and store blood collection tubes. Furthermore, it is conceivable that a cover structure can be provided above the uppermost storage section 200, used to open or close the storage box 220 of the uppermost storage section 200.

[0046] The blood collection tube storage device with the above-described structure can store blood collection tubes in layers through multiple storage sections 200. When storing or retrieving blood collection tubes from any storage section 200 other than the uppermost one, one of these sections, along with the one above it, can be rotated circumferentially relative to the other along the mounting shaft 110. This causes the storage boxes 220 of the two storage sections 200 to be radially offset along the rotating cylinder 210, thus exposing the openings at the top of the storage boxes 220 of the two sections. Then, the operation... Personnel can then access blood collection tubes in the storage box 220 of the storage section 200 without removing other storage sections 200 located on top of the storage section 200, making access very convenient. In addition, since each storage section 200 has two storage boxes 220, which are respectively connected to opposite sides of the radial direction of the rotating drum 210, the offset of the center of gravity of the storage section 200 relative to the central axis of the mounting shaft 110 can be reduced during the rotation of the storage section 200, preventing the device from tipping over and ensuring high structural stability.

[0047] It is understandable that, in order to allow the storage boxes 220 of two adjacent storage sections 200 to be staggered along the circumference of the rotating cylinder 210, in some specific embodiments, the outer contour of the cross-section of the storage box 220 is fan-shaped, and the central angle is less than or equal to ninety degrees.

[0048] Understandably, in order to minimize the offset of the center of gravity of the storage section 200 when it rotates relative to the mounting shaft 110, in some specific embodiments, the two storage boxes 220 of the storage section 200 are arranged symmetrically about the central axis of the rotating cylinder 210.

[0049] Reference Figure 4 As shown, in some embodiments of this utility model, a tube rack 221 is provided inside the storage box 220, and multiple slots 222 are horizontally spaced on the tube rack 221 for insertion of blood collection tubes. It should be noted that one storage section 200 only stores one layer of blood collection tubes.

[0050] Reference Figures 1 to 3As shown, in some embodiments of this utility model, the blood collection tube storage device further includes a locking mechanism 300, which includes a mounting portion 310 and a locking portion 320. The locking portion 320 is vertically adjustable relative to the mounting portion 310. One of each pair of adjacent storage portions 200 is equipped with the locking mechanism 300, and the other is provided with a locking hole 201. The locking hole 201 is used to allow the locking portion 320 to be inserted when the two adjacent storage portions 200 are vertically aligned, thereby locking the two adjacent storage portions 200 relative to each other and preventing relative rotation between the two adjacent storage portions 200. This prevents the opening at the top of the storage box 220 of the lower storage portion 200 from being exposed when blood collection tubes are not needed, thus preventing accidental opening of the storage box 220 and subsequent water or dust ingress.

[0051] It is evident that the locking part 320 can be vertically adjusted to disengage from the locking hole 201 so that two adjacent storage parts 200 can rotate relative to each other.

[0052] Reference Figure 3 As shown, in some embodiments of this utility model, the locking part 320 is vertically slidably mounted on the mounting part 310. The locking mechanism 300 also includes an elastic part 330, which is disposed between the mounting part 310 and the locking part 320. The elastic part 330 is used to apply an elastic force vertically toward the locking hole 201 to the locking part 320. Thus, when two adjacent storage parts 200 are vertically aligned, the elastic force of the elastic part 330 can be used to insert the locking part 320 into the locking hole 201 and maintain it in this state. When it is necessary to disengage the locking part 320, only a reaction force greater than the elastic force of the elastic part 330 needs to be applied to the locking part 320, which is very convenient to operate.

[0053] Reference Figure 1 and Figure 3 As shown, in some embodiments of this utility model, in order to improve the locking stability of the locking mechanism 300, the locking mechanism 300 between two adjacent storage portions 200 is provided on the upper storage portion 200, while the corresponding locking hole 201 is provided on the lower storage portion 200, and the elastic portion 330 can apply a downward elastic force to the locking portion 320, so that the locking portion 320 is subjected to two downward forces: the elastic force and its own weight.

[0054] It is understood that the locking mechanism 300 can be installed on the outer periphery of the storage box 220, and in some embodiments, refer to Figure 3 and Figure 6As shown, the outer peripheral wall of the storage box 220 is provided with a mounting plate 223. Several vertically extending studs 224 are provided on the mounting plate 223. The mounting part 310 is supported on the mounting plate 223. A mounting hole 313 is provided at the bottom of the mounting part 310. The studs 224 pass through the mounting hole 313 and are threaded with a locking nut 225 on the upper side of the mounting hole 313, so that the mounting part 310 can be detachably mounted on the mounting plate 223. Clearly, the mounting plate 223 has clearance holes for the locking part 320 to pass through.

[0055] Reference Figure 3 and Figure 6 As shown, in some embodiments of this utility model, the mounting part 310 is provided with a vertically extending sliding hole 311, the locking part 320 is provided with a rod-shaped structure, the locking part 320 slides vertically through the sliding hole 311, the locking part 320 is provided with a boss 321 on the side of the sliding hole 311 near the locking hole 201, and a limiting part 340 is detachably connected to the side of the sliding hole 311 away from the locking hole 201, the elastic part 330 is provided with a compression spring, the compression spring is sleeved on the locking part 320, and its two ends abut against the mounting part 310 and the boss 321 respectively, thereby applying an elastic force toward the locking hole 201 to the locking part 320. The structure is simple and stable.

[0056] Obviously, the boss 321 is located in the middle of the length direction of the locking part 320.

[0057] Reference Figure 3 and Figure 6 As shown, in some embodiments of this utility model, the limiting part 340 includes a threaded cylinder 341 and a pull plate 342. The threaded cylinder 341 is threadedly connected to the locking part 320. The threaded cylinder 341 is used to abut against the end of the mounting part 310 away from the locking hole 201 to limit the locking part 320 from disengaging from the mounting part 310. The pull plate 342 is fixed to the end of the threaded cylinder 341 away from the mounting part 310, and the pull plate 342 protrudes radially from the threaded cylinder 341. In this way, the pull plate 342 can provide the operator with a better position to apply force and pull the locking part 320, thereby disengaging the locking part 320 from the locking hole 201.

[0058] Reference Figure 3 and Figure 6 As shown, in some embodiments of this utility model, the mounting part 310 defines a mounting cavity 312. The mounting cavity 312 is opened on the side near the locking hole 201. When the limiting part 340 abuts against the end of the mounting part 310 away from the locking hole 201, the boss 321 and the compression spring are both located in the mounting cavity 312. In this way, the compression spring can be built into the mounting part 310, reducing the contact between the compression spring and the external environment, and preventing it from being corroded or stuck by foreign objects.

[0059] Obviously, the sliding hole 311 is located on the side of the mounting cavity 312 away from the locking hole 201.

[0060] Reference Figure 1 and Figure 4 As shown, in some embodiments of this utility model, a first positioning structure is provided on the base 100. The first positioning structure is used to cooperate with the lowermost storage part 200 to restrict the rotation of the lowermost storage part 200 relative to the mounting shaft 110. In this way, when all storage parts 200 are locked to each other by the cooperation of the locking mechanism 300 and the locking hole 201, the rotation of all storage parts 200 relative to the mounting shaft 110 can be restricted by the first positioning structure, thus preventing the storage parts 200 from rotating arbitrarily.

[0061] In some specific embodiments, such as Figure 1 and Figure 4 As shown, the first positioning structure includes two first positioning pins 101, which are vertically distributed and along the circumference of the rotating cylinder 210. The two first positioning pins 101 respectively abut against the adjacent side walls of the two storage boxes 220 of the lowermost storage part 200.

[0062] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the blood collection tube storage device further includes a cover plate 400. The cover plate 400 is adjustablely disposed above the uppermost storage box 220. The cover plate 400 is used to open or close the uppermost storage box 220. The cover plate 400 is the closing structure described in the above embodiments. When it is necessary to store or retrieve blood collection tubes in the uppermost storage section 200, the cover plate 400 is adjusted to open the storage box 220 of the storage section 200. It should be noted that in this embodiment, opening the storage box 220 means fully exposing the opening at the top of the storage box 220.

[0063] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the cover plate 400 is provided with a sleeve hole 410 and is sleeved on the mounting shaft 110 through the sleeve hole 410. The lower surface of the cover plate 400 is provided with a second positioning structure. The cover plate 400 can slide vertically relative to the mounting shaft 110 to allow the second positioning structure to be inserted into or removed from the uppermost storage box 220. When the second positioning structure is inserted into the uppermost storage box 220, it can restrict the relative rotation between the cover plate 400 and the uppermost storage box 220, and the cover plate 400 closes the uppermost storage box 220. When the second positioning structure is removed from the uppermost storage box 220, the cover plate 400 can rotate around the central axis of the mounting shaft 110 to open the uppermost storage box 220, that is, to fully expose the opening at the top of the uppermost storage box 220.

[0064] Reference Figure 5 As shown, in some embodiments of this utility model, the second positioning structure includes two second positioning pins 420. When the second positioning structure is embedded in the storage box 220, the two second positioning pins 420 respectively abut against the two inner walls of the storage box 220 that are opposite each other in the circumferential direction along the rotating cylinder 210.

[0065] Reference Figure 4 As shown, in some embodiments of this utility model, a pull rod 430 is provided on the upper surface of the cover plate 400 to facilitate the operator to lift the cover plate 400 so that it slides or rotates relative to the mounting shaft 110.

[0066] Reference Figure 1 and Figure 4 As shown, in some embodiments of this utility model, a support seat 120 is provided at the bottom end of the mounting shaft 110 of the base 100. The support seat 120 is used to support the storage part 200. A handle part 130 is detachably connected to the upper side of the cover plate 400 of the mounting shaft 110 to provide a position for the operator to apply force and lift the entire blood collection tube storage device.

[0067] Reference Figure 1 and Figure 4 As shown, in some embodiments of this utility model, the handle portion 130 is provided with an installation cylinder 131 and a lifting handle 132.
