Description

Technical Field

[0001] The present invention relates to the technical field of specimen storage boxes, and particularly relates to a multifunctional biological specimen storage box device for tuberculosis wards. Background Technique

[0002] Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis infection, which can invade many parts and organs of the body. Pulmonary tuberculosis infection is the most common, and it can also infect other parts outside the lungs. Therefore, the body fluid types of tuberculosis patients are diverse, including sputum, bronchoalveolar lavage fluid, blood, cerebrospinal fluid, pleural effusion, ascites, urine, feces, secretions, and puncture fluid from suspected infected sites. Mycobacterium tuberculosis may be found in these specimens, which have strong infectivity.

[0003] Currently, for the storage of specimens from tuberculosis patients in clinical practice, ordinary biological specimen storage boxes are usually used. However, ordinary storage boxes have many deficiencies. On the one hand, tuberculosis patients have particularities, including latent Mycobacterium tuberculosis carriers, active tuberculosis (smear-positive pulmonary tuberculosis, smear-negative pulmonary tuberculosis, culture-positive pulmonary tuberculosis, culture-negative pulmonary tuberculosis, molecular biology-positive pulmonary tuberculosis, pulmonary tuberculosis without sputum examination), etc. Specimens from different types of patients need to be placed in separate areas to avoid cross-infection. However, ordinary storage boxes lack a reasonable partition structure and cannot meet the classification storage requirements for specimens from different types of patients. On the other hand, it is not convenient to move the support frame for storing samples in ordinary storage boxes, which is not conducive to the storage and retrieval of samples.

[0004] Therefore, it is necessary to provide a multifunctional biological specimen storage box device for tuberculosis wards to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional biological specimen storage box device for tuberculosis wards to solve the problem in the above background technique that the existing storage boxes cannot partition and place specimens from different types of patients to avoid cross-infection.

[0006] Based on the above idea, the present invention provides the following technical solution: A multifunctional biological specimen storage box device for tuberculosis wards includes a box body and a plurality of partitions fixed inside the box body. A pull plate is arranged between adjacent two partitions. Multiple groups of support components for placing specimens are arranged inside the pull plate. A guide block is arranged on the outer wall of the pull plate, and a straight groove slidably matched with the guide block is opened on the inner wall of the box body. A recessed part is formed by the inward depression of the inner wall of the box body near the top. The bottom surface of the recessed part is a support platform. When the pull plate deflects to the horizontal state, the guide block can fall onto the support platform. A rotating shaft is rotatably connected inside the guiding block. One end of the rotating shaft away from the pulling plate is elastically connected with a clamping block. A clamping groove matching with the clamping block is arranged on the inner wall of the concave part. When the clamping block is clamped with the clamping groove, the pulling plate can rotate around the clamping block. When the pulling plate rotates to a horizontal state, the guiding block can be separated from the box body, so that the pulling plate can slide on the top of the box body.

[0007] As a further scheme of the present invention: both the clamping block and the clamping groove are of polygonal structures.

[0008] As a further scheme of the present invention: the guiding block is of a cuboid structure, the length of the guiding block is longer than the width of the straight groove, and a convex platform is fixedly arranged at a position on the outer wall of the pulling plate close to the top. When the pulling plate deflects to a horizontal state, both the convex platform and the guiding block can be on the supporting platform.

[0009] As a further scheme of the present invention: a connecting ring is fixedly sleeved on the outer side of the rotating shaft, a square rod is fixedly arranged at the end face of the clamping block close to the rotating shaft, a square groove slidably matched with the square rod is arranged at the end face of the rotating shaft, a magnetic block is slidably assembled on the outer peripheral wall of the connecting ring, a traction rope is fixedly arranged between the magnetic block and the square rod, a sleeve ring is sleeved on the outer side of the connecting ring, the sleeve ring is rotatably matched with the guiding block, and a plurality of magnetic plates are fixedly embedded on the inner wall of the sleeve ring, and the magnetic block is between two adjacent magnetic plates.

[0010] As a further scheme of the present invention: an arc-shaped groove is arranged on the inner wall of the box body on one side of the straight groove, and both ends of the arc-shaped groove are communicated with the straight groove and the concave part respectively. A protrusion is fixedly arranged at a position on the outer wall of the pulling plate below the guiding block. During the locking of the clamping block and the clamping groove and the rotation of the pulling plate, the protrusion can slide from the straight groove into the arc-shaped groove and finally enter the concave part.

[0011] As a further scheme of the present invention: a stop rod is arranged at the junction of the arc-shaped groove and the straight groove, the stop rod is elastically connected with the box body, and the part of the stop rod located outside the box body is of an arc surface structure.

[0012] As a further scheme of the present invention: the support assembly includes a test tube rack and a support plate arranged below the test tube rack. A support rod is arranged at the inner side position of the pulling plate, the top end of the support rod is rotatably connected with the pulling plate through a pin shaft, and both the test tube rack and the support plate are fixedly connected with the support rod.

[0013] As a further scheme of the present invention: a spring is fixedly arranged between the inner end face of the square groove and the square rod.

Detailed implementation manner

[0020] As Figures 1 - 10 shown, a multifunctional biological specimen storage box device for a tuberculosis ward area includes a box body 1 and a plurality of partition boards 102 fixed inside the box body 1. An area for placing specimens is formed between two adjacent partition boards 102. Through this structure, various specimens can be classified and stored. Furthermore, a pulling plate 2 with a U-shaped structure is arranged between two adjacent partition boards 102. Referring to Figure 3 shown, a plurality of support assemblies for placing test tubes are arranged inside the pulling plate 2, and the support assemblies can rotate relative to the pulling plate 2. Through this structure, during the process of the pulling plate 2 moving to the top position of the box body 1 and deflecting to a horizontal state, the support assemblies can remain stable without rotating. Referring to Figure 4 shown, Figure 4 in

[0021] Figures 2 - 5 Figure 2

[0022] the pulling plate 2 is pulled to the top of the box body 1 and deflected to a horizontal state. In this state, it is beneficial for medical staff to take and store the test tubes containing specimens.

[0022] A rotating shaft 12 is rotatably connected inside the guiding block 4, and the rotating shaft 12 is connected to the guiding block 4 through a torsion unit. With this structure, the stability of the rotating shaft 12 can be maintained in the initial state. One end of the rotating shaft 12 away from the pulling plate 2 is elastically connected with a clamping block 11. Combining Figure 2 , Figure 7 As shown, a clamping groove 106 matching with the clamping block 11 is formed on the inner wall of the recessed portion 103. When the clamping block 11 is inside the clamping groove 106, a gap is left between the outer wall of the clamping block 11 and the inner wall of the clamping groove 106. Both the clamping block 11 and the clamping groove 106 are of polygonal structures. Preferably, the clamping block 11 and the clamping groove 106 are of quadrilateral structures. When the guiding block 4 moves out of the straight groove 105 and enters the recessed portion 103, the clamping block 11 at the end of the guiding block 4 can be inserted into the clamping groove 106. With this structure, the position of the pulling plate 2 near the bottom end can be locked. At this time, the pulling plate 2 can rotate around the clamping block 11; Figure 5 Two states of the guiding block 4 are shown in . Specifically, during the process of pulling up the pulling plate 2, the guiding block 4 is in a vertical state and slides in the straight groove 105. When the guiding block 4 moves out of the straight groove 105 and enters the recessed portion 103, the guiding block 4 can deflect to a horizontal state along with the pulling plate 2. Specifically, the guiding block 4 is of a cuboid structure. The width of the guiding block 4 is equal to or slightly smaller than the width of the straight groove 105, while the length of the guiding block 4 is longer than the width of the straight groove 105. With this structure, when the guiding block 4 deflects to the horizontal state, it can be on the supporting platform 1031, and the guiding block 4 can slide along the supporting platform 1031 without being restricted by the straight groove 105; Figures 3 - 4 As shown in

[0023] On the outer wall of the pulling plate 2 and near the top end, a convex platform 3 with the same size as the guiding block 4 is fixedly arranged. When the pulling plate 2 deflects to the horizontal state, both the convex platform 3 and the guiding block 4 can be on the supporting platform 1031, which is beneficial for the pulling plate 2 to slide on the top of the supporting platform 1031. At this time, medical staff can take and store the test tubes on the supporting assembly. During actual use, the side edges of the convex platform 3 and the guiding block 4 are chamfered. Figure 7 When the pulling plate 2 needs to be unlocked from the box body 1 after deflecting from the vertical state to the horizontal state, for this purpose, a connecting ring 16 is fixedly sleeved outside the rotating shaft 12. Referring to Figure 9As shown, the magnetic block 20 can slide along the diameter direction of the connecting ring 16, and a traction rope 19 is fixedly arranged between the magnetic block 20 and the square rod 1101. The traction rope 19 can be made of steel wire. Figure 9 The direction of the magnet 20 passes through the rotating shaft 12 and the connecting ring 16 and slides with the two. Through this structure, when the magnetic block 20 moves outward relative to the connecting ring 16, the square rod 1101 can be pulled, so that the card block 11 is stored in the guide block 4; Combination Figures 9 - 11 As shown, a collar 15 is sleeved on the outer side of the connecting ring 16, and the collar 15 is rotatably matched with the guide block 4. A plurality of magnetic plates 1501 are fixedly embedded on the inner wall of the collar 15. Figure 11 The magnetic block 20 is arranged in a circular array as shown in FIG. 1 , and the magnetic block 20 is located between two adjacent magnetic plates 1501. Specifically, Figure 11 There are four sets of middle magnetic plates 1501 , so each time the collar 15 rotates 90°, the magnetic plates 1501 can be aligned with or staggered from the magnetic blocks 20 .

[0024] In actual operation, in order to facilitate the rotation of the collar 15, a bevel gear ring 14 is fixedly mounted on the outer side of the collar 15, and a bevel gear 17 is meshed on the outer side of the bevel gear ring 14. A connecting shaft 18 is arranged on the side of the bevel gear 17 away from the collar 15. The connecting shaft 18 passes through the guide block 4 and rotates with it through a bearing. In the initial state, the support assembly is Figure 6 The state shown is placed in the pull plate 2, and the pull plate 2 is inserted between two adjacent partitions 102 and in contact with them. Through this structure, a variety of specimens can be classified and stored; When it is necessary to take or store the specimen, the pull plate 2 can be pulled upwards. During this process, the guide block 4 can slide upwards along the straight groove 105. When the guide block 4 moves out of the straight groove 105 and enters the recessed portion 103, the block 11 can be aligned with the slot 106, so that the block 11 can pop out and be inserted into the slot 106. Since the block 11 and the slot 106 are both polygonal structures, the block 11 is restricted and cannot rotate. When the top end of the pull plate 2 is driven to deflect, the entire pull plate 2 will rotate with the block 11 as the center, and the guide block 4 will rotate synchronously with the pull plate 2. According to the above description and in combination Figure 5 It can be seen that when the pull plate 2 rotates 90°, it can be in a horizontal state, and the guide block 4 rotates 90° and falls on the top of the support platform 1031. At this time, through the cooperation of the boss 3 and the guide block 4, the pull plate 2 can be stably located at the top of the box body 1; The cooperation between the block 11 and the slot 106 can prevent the rotating shaft 12 from rotating. Therefore, when the pull plate 2 deflects 90°, the magnetic plate 1501 on the ring 15 can be aligned with the magnetic block 20 on the rotating shaft 12, and the opposite side of the magnetic block 20 and the magnetic plate 1501 has different magnetic poles. Therefore, the suction force between the two enables the magnetic block 20 to pull the traction rope 19, and then the traction rope 19 pulls the block 11. When the block 11 moves out of the slot 106 and enters the guide block 4, the guide block 4 is disengaged from the box 1, so that the pull plate 2 can slide left and right at the top of the box 1, which is convenient for medical staff to take or place test tubes. Since the support assembly cooperates with the pull plate 2 in rotation, the support assembly always remains in a vertical state during the rotation of the pull plate 2 to a horizontal state, so that the test tubes on the support assembly can be fully exposed, thereby providing convenience for taking or storing specimens.

[0025] When the pull plate 2 needs to be reinserted between the two adjacent partitions 102, the pull plate 2 can be moved to the side of the two empty partitions 102 first. Then, the medical staff rotates the connecting shaft 18, and the meshing of the bevel gear 17 and the bevel gear ring 14 drives the collar 15 to rotate 90° (in actual use, by controlling the gear ratio of the bevel gear 17 and the bevel gear ring 14, the connecting shaft 18 rotates one circle or N circles to drive the collar 15 to rotate 90°), so that the magnetic plate 1501 on the collar 15 is offset from the magnetic block 20, so that the block 11 can be ejected again. When the pull plate 2 is pushed to slide in the horizontal direction again so that the block 11 is aligned with the slot 106, the block 11 can pop out and be inserted into the slot 106, which is convenient for medical staff to rotate the pull plate 2 to a vertical state. According to the above description, since the block 11 is restricted by the slot 106, when the pull plate 2 is rotated to a vertical state, the ring 15 can rotate relative to the connecting ring 16, so that the magnetic plate 1501 and the magnetic block 20 can be realigned. When the block 11 is out of the slot 106, the pull plate 2 can be re-inserted downward between the two partitions 102.

[0026] To sum up, in the process of pulling out the pull plate 2 of this device, the position of the pull plate 2 near the bottom can be automatically locked with the box body 1, which is conducive to rotating the pull plate 2 to a horizontal state, so that the specimens on the supporting assembly can be fully exposed, which is conducive to taking or storing the specimens, and the pull plate 2 can slide on the top of the box body 1, so that multiple medical staff can take or store the specimens on the pull plate 2 at different positions. In addition, the expansion and contraction of the block 11 can be controlled by the cooperation of the bevel gear ring 14 and the bevel gear 17, which is conducive to rotating the horizontal pull plate 2 back to a vertical state and inserting it between two adjacent partitions 102.

[0027] like Figures 1 - 10As shown, in order to facilitate the rotation of the connecting shaft 18, a spur gear 10 is fixedly arranged at the top of the connecting shaft 18 in this solution. A mark such as a scale line can be set on the top surface of the spur gear 10 to facilitate medical staff to confirm how many turns the spur gear 10 has rotated. Figures 6 - 7 As shown, a rack 9 meshing with a spur gear 10 is fixedly provided at the bottom end of the interior of the box body 1. When the pull plate 2 is inserted between the two partitions 102, the spur gear 10 can mesh with the rack 9. Specifically, the connecting shaft 18 cooperates with the spur gear 10 through a one-way bearing, so that only when the pull plate 2 moves downward can the bevel gear 17 be driven to rotate through the meshing of the spur gear 10 and the rack 9. In the process of pulling the pull plate 2 to move upward, the bevel gear 17 can remain stable. In specific use, when the pull plate 2 is inserted between the two partitions 102, the meshing of the rack 9 and the spur gear 10 can drive the bevel gear 17 to rotate, thereby driving the ring 15 to rotate, so that the magnetic plate 1501 is staggered with the magnetic block 20. When the pull plate 2 is pulled out for the next time, the pull plate 2 can still be automatically locked with the box body 1.

[0028] Reference Figures 1 - 2 As shown, a cover plate 101 is hinged on the top of the box body 1, and a handle is fixedly provided on the top surface of the pull plate 2. Figures 2 - 3 , Figure 6 As shown, an arc groove 104 is provided on the inner wall of the box body 1 at one side of the straight groove 105, and the two ends of the arc groove 104 are respectively connected with the straight groove 105 and the recessed portion 103, and a protrusion 5 is fixedly provided on the outer wall of the pull plate 2 at a position below the guide block 4. When the clamping block 11 is locked with the clamping groove 106 and the pull plate 2 rotates, the protrusion 5 can slide from the straight groove 105 to the arc groove 104 and finally enter the recessed portion 103, and the protrusion 5, the boss 3 and the guide block 4 are arranged in a colinear manner; Further, refer to Figure 4 As shown, with the center of the box body 1 as the boundary, the deflection directions of the arc grooves 104 on the left and right sides can be set oppositely. In this way, the pull plate 2 on the left side of the box body 1 can be deflected clockwise downward, while the pull plate 2 on the right side of the box body 1 can be deflected counterclockwise downward. Figure 10 As shown, a baffle 21 can be provided at the junction of the arc groove 104 and the straight groove 105. Specifically, a strip groove slidably matched with the baffle 21 can be provided on the inner wall of the box body 1, so that the baffle 21 is elastically connected to the strip groove through a spring, and the portion of the baffle 21 located on the outside of the box body 1 is an arc surface structure. Through this structure, when the clamping block 11 cooperates with the clamping groove 106 and drives the pull plate 2 to rotate to a vertical state, the protrusion 5 can return to the straight groove 105 along the arc groove 104, and the protrusion 5 can be limited by the baffle 21, so that the protrusion 5 is stably placed in the straight groove 105, which is conducive to stably inserting the pull plate 2 between the two partitions 102.

[0029] Refer to Figure 3 、 Figure 6 and Figure 8 As shown, the support assembly includes a test tube rack 6 and a support plate 7 arranged below the test tube rack 6. A plurality of holes are formed on the surface of the test tube rack 6. A support rod 8 is arranged at the inner side position of the pull plate 2. The top end of the support rod 8 is rotationally connected to the pull plate 2 through a pin shaft, and both the test tube rack 6 and the support plate 7 are fixedly connected to the support rod 8.

[0030] Refer to Figure 6 As shown, when the pull plate 2 is inserted between the two partition plates 102, the connecting shaft 18 is located at the side position of the guide block 4, which is beneficial for cooperation with the rack 9. When the pull plate 2 is in a horizontal state, the connecting shaft 18 is arranged upward, which is beneficial for operation.

[0031] Refer to Figures 7 - 9 As shown, a receiving groove for cooperating with the block 11 is formed at the end face position of the guide block 4. A spring is fixedly arranged between the inner end face of the square groove and the square rod 1101. An annular groove for accommodating structures such as the collar 15, the bevel gear ring 14, and the bevel gear 17 is formed in the guide block 4. Both the collar 15 and the connecting ring 16 rotate in the annular groove. During actual use, an annular plate 13 can be fixedly sleeved outside the collar 15, and a rubber ring can be embedded on the outer peripheral wall of the annular plate 13. The friction between the rubber ring and the inner wall of the annular groove can keep the collar 15 stable. An installation groove 401 is also formed at the end position of the guide block 4 where the tail end of the rotating shaft 12 is located, and the above-mentioned torsion unit is located in this installation groove 401. Specifically, the torsion unit can be a torsion spring or a coil spring, and both ends of the torsion unit are respectively connected to the rotating shaft 12 and the inner wall of the installation groove 401.
