[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0027] In current clinical practice, test samples are often stored in foam boards. Medical staff have found that samples that have been centrifuged and decapped are very easy to spill. After testing, samples are often sealed and transported in disposable plastic wrap or plastic bags. The lack of airtightness can also cause samples to spill during storage or transportation, affecting the testing and biosafety of the samples.
[0028] To resolve the above technical issues, please refer to Figures 1 to 4 This application provides a sample storage device 100, which may include a housing 110, a cover 130 and a sample tube 120, wherein the sample tube 120 is used to hold a sample 200, which is generally a tubular structure for holding blood, urine, etc.
[0029] Specifically, the housing 110 has a receiving cavity with an open opening, and the cover 130 is sealed to the open opening for opening or closing. The sample tube 120 is located in the receiving cavity and is fixed to the peripheral wall of the receiving cavity. The sample tube 120 includes a tube body 121 and a limiting block 122. The opening of the tube body 121 faces the open opening, and a limiting hole is provided on the peripheral wall of the tube body 121. The limiting block 122 is movably disposed in the limiting hole.
[0030] The limiting block 122 includes an active position (e.g. Figure 3 The position of the limit block shown) and the locking position (e.g.) Figure 4 (As shown in the diagram, the position of the limiting block 122) When the limiting block 122 is in the active position, the limiting block 122 is at least partially located outside the tube body 121 and spaced apart from the sample 200, so that the sample 200 can be placed into the tube body 121 without obstruction. When the limiting block 122 is in the locked position, the limiting block 122 is at least partially located inside the tube body 121 and abuts against the sample 200, so that the limiting block 122 can limit the sample 200 circumferentially and reduce the occurrence of sample 200 shaking.
[0031] In this way, when medical staff need to transfer sample 200, they can first open the cover 130 of the sample storage device, adjust the limiting block 122 to the movable position, then place sample 200 in sample tube 120, and then adjust the limiting block 122 to the locked position to limit the periphery of sample 200. Then, the cover 130 is closed and the sample storage device 100 is moved to realize the transfer of sample 200. In this process, by setting the limiting block 122 to limit the circumference of sample 200, the situation of sample 200 tipping over or spilling during storage and transportation can be avoided.
[0032] Meanwhile, the cooperation between the cover 130 and the box 110 provides a containment cavity for the sample 200 that is isolated from the outside world, ensuring biosafety.
[0033] In order to fix the sample tube 120, the sample storage device 100 also includes a sample placement plate 170. The sample placement plate 170 is located in the receiving cavity and fixed to the peripheral wall of the box 110. The sample tube 120 is placed on the sample placement plate 170.
[0034] Specifically, the cross-section of the sample placement plate 170 can be adapted to the cross-section of the receiving cavity, and the circumferential edge of the sample placement plate 170 can be bonded to the inner wall of the receiving cavity to achieve the fixation between the sample placement plate 170 and the inner wall of the receiving cavity.
[0035] It can be understood that in a specific medical process, the number of samples 200 is generally multiple. Therefore, in the specific implementation process, the number of sample tubes 120 can also be multiple, with multiple sample tubes 120 evenly arranged on the sample placement plate 170.
[0036] Furthermore, the number of sample tubes 120 can be 12, 16, 20, 24, 25, etc.
[0037] In the embodiments of this application, the sample placement plate 170 is provided with a plurality of sample placement holes, and the sample tube 120 is inserted into the sample placement holes, thereby fixing the sample tube 120 in the receiving cavity.
[0038] In the embodiments of this application, in the direction of the open opening toward the bottom wall of the housing 110, the limiting block 122 includes a first end 1221 and a second end 1222 opposite to each other. The first end 1221 is close to the bottom wall and is rotatably connected to the inner wall of the limiting hole. The second end 1222 can pass through the limiting hole.
[0039] Specifically, the limiting block 122 is rotatably connected to the limiting hole, and the second end 1222 can rotate about the first end 1221 as the central axis. Therefore, the second end 1222 can switch positions between inside and outside the sample tube 120, thereby achieving the separation and contact with the sample 200, and thus achieving the switching between the active position and the locked position.
[0040] Furthermore, the first end 1221 is provided with a rotating shaft, and the inner wall of the limiting hole is provided with a rotating hole. The rotating shaft rotates through the rotating hole, and a torsion spring is sleeved on the rotating shaft. The two pins of the torsion spring abut against the inner wall of the tube body 121. The torsion spring always provides the limiting block 122 with a force to rotate from the locked position to the active position.
[0041] Thus, by setting a rotating shaft and a rotating hole, the limiting block 122 and the tube body 121 are rotatably connected, and by setting a torsion spring, a thrust is provided for the rotation of the limiting block 122 toward the movable position.
[0042] Furthermore, during the process of the limiting block 122 moving from the locked position to the active position, in order to make the limiting block 122 stop when it moves to the active position, a limiting flange 1223 is provided on the side of the second end 1222 facing the tube body 121. The limiting flange 1223 is located inside the tube body 121. When the limiting block 122 is in the active position, the limiting flange 1223 abuts against the inner wall of the tube body 121.
[0043] In this way, on the one hand, the limit block 122 can be stopped when it moves to the active position, reducing the stroke of the limit block 122 during rotation and thus improving the stability of the limit block 122 during rotation; on the other hand, it can prevent the limit block 122 from detaching from the tube body 121.
[0044] In the embodiments of this application, please refer to Figures 2 to 5 The sample storage device 100 may further include a movable plate 140, which is disposed between the sample tube 120 and the bottom wall of the housing 110. The movable plate 140 can be positioned with its opening facing the bottom wall (e.g., Figure 2 The moving plate 140 moves back and forth in the up and down direction shown in the figure. It is provided with a locking hole 141, which is opposite to the sample tube 120. The opening of the locking hole 141 faces the sample tube 120.
[0045] The movable plate 140 includes a first position and a second position. When the movable plate 140 is in the first position, the sample tube 120 extends into the locking hole 141, and the side wall of the locking hole 141 abuts against the limiting block 122, squeezing the limiting block 122 to the locked position. When the movable plate 140 is in the second position, the side wall of the locking hole 141 is spaced apart from the limiting block 122.
[0046] It should be noted that the first position of the moving plate 140 is on the side of the moving plate 140 facing the cover 130 in the second position. During the process of the moving plate 140 moving from the second position to the first position, that is, during the process of the moving plate 140 moving towards the cover 130, the sample tube 120 will extend into the locking hole 141 and then abut against the limiting block 122, squeezing the limiting block 122 so that part of the limiting block 122 extends into the tube body 121 until the limiting block 122 moves to the locking position.
[0047] As the moving plate 140 moves from the first position to the second position, the sample tube 120 gradually disengages from the locking hole 141, the squeezing force on the limiting block 122 is removed, and under the action of the torsion spring, the limiting block 122 returns to the active position.
[0048] Thus, by setting the movable plate 140, the limit block 122 can be switched between the active position and the locked position.
[0049] When the limiting block 122 is in the active position, in the direction of the open opening towards the bottom wall, the side surface of the limiting block 122 away from the tube body 121 extends obliquely toward the central axis of the tube body 121.
[0050] Therefore, during the process of the sample tube 120 extending into the limiting hole, the surface of the limiting block 122 on the side opposite to the tube body 121 plays a guiding role, converting the pushing force of the moving plate 140 on the limiting block 122 in the vertical direction into the force of the limiting block 122 moving radially in the sample tube 120, thereby realizing the rotation of the limiting block 122 from the active position to the locked position.
[0051] Please refer to some embodiments of this application. Figure 2 The sample storage device 100 may also include a first magnetic element 151, a second magnetic element 152, an elastic element 153, and a power supply element 180.
[0052] The first magnetic element 151 is disposed on the side surface of the movable plate 140 facing the bottom wall of the housing 110, and the second magnetic element 152 is disposed on the side surface of the bottom wall of the housing 110 facing the movable plate 140. The second magnetic element 152 is an electromagnet. One end of the elastic element 153 abuts against the first magnetic element 151 and the other end abuts against the second magnetic element 152. The power supply element 180 is electrically connected to the second magnetic element 152. The elastic element 153 can be a spring.
[0053] It is understandable that the elastic element 153 always applies a pushing force to the first magnetic element 151. The first magnetic element 151 can be a permanent magnet. When the second magnetic element 152 is not energized, there is an attractive force between the first magnetic element 151 and the electromagnet. The attractive force compresses the elastic element 153, causing the moving plate 140 to move towards the bottom wall. When the second magnetic element 152 is energized, there is a repulsive force between the second magnetic element 152 and the first magnetic element 151. Under the action of the repulsive force and the elastic force of the elastic element 153, the moving plate 140 is moved towards the cover 130.
[0054] Thus, by setting the first magnetic element 151, the second magnetic element 152 and the elastic element 153, the movable plate 140 can move between the first position and the second position.
[0055] The cross-section of the movable plate 140 can be matched with the cross-section of the receiving cavity, which can reduce the occurrence of left and right swaying of the movable plate 140 during movement.
[0056] In the embodiments of this application, the tube body 121 may be provided with two limiting holes, and the number of limiting blocks 122 may be two. The two limiting blocks 122 are symmetrically arranged about the central axis of the tube body 121. In this way, the sample tube 120 can be subjected to uniform force in the circumferential direction, and the occurrence of sample 200 skewing can be further reduced.
[0057] Please refer to the embodiments in this application. Figure 2 The sample storage device 100 may also include a third magnetic element 161 and a magnetic element, the third magnetic element 161 being disposed at the edge of the opening; and a fourth magnetic element 162 being disposed on the side surface of the cover 130 facing the opening, the fourth magnetic element 162 being disposed opposite to the third magnetic element 161.
[0058] The fourth magnetic component 162 can be a permanent magnet.
[0059] In this way, by setting the third magnetic component 161 and the fourth magnetic component 162, the sealing and stability of the cover 130 and the box 110 can be guaranteed.
[0060] Furthermore, the third magnetic component 161 is an electromagnet.
[0061] It should be noted that when the cover 130 needs to be placed over the open opening of the box 110, the third magnetic component 161 is not energized. The attraction between the third magnetic component 161 and the fourth magnetic component 162 ensures the stability of the connection between the cover 130 and the box 110. When the cover 130 needs to be opened, the third magnetic component 161 is energized, and a repulsive force is generated between the third magnetic component 161 and the fourth magnetic component 162, thereby reducing the resistance that medical staff need to overcome when opening the cover 130.
[0062] The third magnetic component 161 is electrically connected to the power supply component 180.
[0063] In the embodiments of this application, the cover 130 is provided with a handle 131 to provide a handhold for medical personnel.
[0064] In the embodiments of this application, the outer surface of the box 110 may also be provided with an identification groove 111, which can be used to identify information of the sample 200.
[0065] In the embodiments of this application, the housing 110 may also be provided with a first switch 112 and a second switch. The first switch 112 is used to control the disconnection and connection of the power supply between the power supply component 180 and the second magnetic component 152, and the second switch is used to control the disconnection and connection of the power supply between the power supply component 180 and the third magnetic component 161.
[0066] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
