Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a blood collection tube holder. Background Technology

[0002] Thoracic surgeons collect patients' blood before and after surgery to check blood indicators such as coagulation, blood sugar, blood lipids, and electrolytes. Blood collection is a routine but important diagnostic and treatment method for checking the patient's physical condition.

[0003] The labels affixed to blood collection tubes are crucial for patient identification and sample tracking. These labels ensure that the patient's identity, the requested procedure, and the actual sample match correctly, preventing errors. Furthermore, modern hospital information systems scan the barcodes or QR codes on the labels, linking the entire process for efficient and accurate blood processing.

[0004] Blood collection tube racks typically have multiple partitions with holes for the blood collection tubes to pass through. After collecting blood, medical staff insert the blood collection tube into the hole in the partition. The holes in the upper and lower partitions keep the blood collection tube vertical. If the upper partition is too high, it will obstruct the label on the blood collection tube, making it difficult for medical staff to read the label information. If the upper partition is set too low to facilitate label reading, its restraining effect on the blood collection tube is reduced, and the blood collection tube may move upwards during transport, detach from the rack, and potentially become contaminated with the sample. Summary of the Invention

[0005] To facilitate medical staff in identifying label information and to ensure the upper partition restricts the blood collection tubes during transport, this application provides a blood collection tube rack.

[0006] A blood collection tube rack includes: a frame body, a top plate connected to the frame body, a control component, a working component, and a clamping component; the working component and the clamping component are disposed below the top plate; the top plate has a plurality of placement holes for blood collection tubes to pass through along the transverse direction of the frame body; the working component is fixedly connected to the frame body and has a first abutment portion corresponding to each placement hole; the clamping component has a second abutment portion corresponding to each placement hole, the second abutment portions being disposed opposite to the first abutment portions in the transverse direction of the frame body; the top plate is movable along the longitudinal direction of the frame body, and a driven portion is disposed below the top plate; the control component is movable along the transverse direction of the frame body to move between a first position and a second position, the control component having an active portion cooperating with the driven portion, the active portion and / or the driven portion being convex. The clamping member is arranged to move laterally along the frame, and the movement path is parallel to the movement path of the control member. When the control member moves from the first position to the second position, the top of the active part that abuts against the driven part gradually approaches the top of the driven part and pushes the top plate to a fixed position. The control member drives the second abutting part to approach the first abutting part that is set with the same placement hole. The first abutting part and the second abutting part clamp into the blood collection tube between them. When the control member moves from the second position to the first position, the top of the active part gradually approaches the root of the driven part. The top plate falls to the display position, and the distance between the first abutting part and the second abutting part can increase. The first abutting part and the second abutting part no longer clamp the blood collection tube.

[0007] In one embodiment of this application, the movement path of the control member further includes a transition position, which is located between the first position and the second position. When the control member is located between the first position and the transition position, the control member contacts the top plate. On the movement path of the control member, the control member and the clamping member are spaced apart and do not contact each other. When the control member is located between the transition position and the second position, the control member contacts the top plate and the clamping member.

[0008] In one embodiment of this application, the clamping member is movable between a clamping position and a releasing position. When the clamping member is in the clamping position, the second abutment and the first abutment can clamp the blood collection tube. When the clamping member is in the releasing position, the blood collection tube can move away from the second abutment and the first abutment. The clamping member is also connected to the frame through a spring, and the spring applies a force to the clamping member in the clamping position to move it toward the releasing position.

[0009] In one embodiment of this application, the frame is slidably connected with a positioning pin, which can move in a direction perpendicular to the movement path of the control component; the control component is provided with a pin hole for the positioning pin to enter and exit, and when the control component reaches the second position, the positioning pin can be inserted into the pin hole.

[0010] In one embodiment of this application, the frame is fixedly connected to a base plate that supports the bottom of the blood collection tube. The base plate is located below the clamping member and the working member. The clamping member and the working member are provided with through holes for the blood collection tube to pass through. The through hole of the clamping member is an elongated hole, and its length direction is parallel to the movement path of the clamping member. The first abutment part and the second abutment part are provided along the edge of the through hole.

[0011] In one embodiment of this application, the through hole provided in the working part is a round hole; the working part and the clamping part are spaced apart in the longitudinal direction of the frame, and the first abutting part and the second abutting part are provided between the working part and the clamping part.

[0012] In one embodiment of this application, the frame is provided with a limiting block at the display position to prevent the top plate from falling further.

[0013] In one embodiment of this application, the frame is provided with a limiting block at a fixed position to prevent the top plate from moving upward.

[0014] In one embodiment of this application, the top plate is slidably connected to the frame.

[0015] In one embodiment of this application, the clamping component, the control component, and the frame are slidably connected.

[0016] The beneficial effects of this application are at least as follows: When the control unit is in the first position, the top plate is at a lower height, which fully exposes the blood collection tube labels placed on the tube rack, making it easier for medical staff to identify the label information.

[0017] When the control unit switches from the first position to the second position, the active part pushes the driven part upward, causing the height of the top plate to rise. The control unit also drives the second abutment of the clamping part to approach the first abutment of the working part. The second abutment and the first abutment clamp the blood collection tube between them to prevent the blood collection tube from falling off the tube rack, making it easier to transfer multiple blood collection tubes on the tube rack to other positions.

[0020] To provide a clearer understanding of the technical features, objectives, and effects of this application, specific embodiments of this application are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0021] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0022] To keep the drawings concise, only the parts relevant to this application are shown schematically in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0023] The "fixed connection" between the two components in this application is achieved through methods such as integral manufacturing, threaded connection, snap welding, and bonding, so that the relative position between the two components does not change or rotate relative to each other during use.

[0024] The movement of one component relative to another component in this application can be configured such that the two components slide relative to each other along a preset path, or that one component moves relative to another component by means of the rolling of a rolling element.

[0025] Please see Figures 1 to 10 Learn more about this application.

[0026] See Figure 1 , Figure 2 The blood collection tube frame includes: a frame body 101, a top plate 201 connected to the frame body 101, a control component 501, a working component 301, and a clamping component 401; the control component 501, the working component 301, and the clamping component 401 are located below the top plate 201.

[0027] See Figure 1 The top plate 201 has multiple placement holes 202 along the transverse direction of the frame 101 for the blood collection tubes 601 to pass through. The axial direction of the placement holes 202 is parallel to the longitudinal direction (height direction) of the frame 101, so that multiple placement holes 202 can accommodate multiple blood collection tubes 601. The top plate 201 is slidably connected to the top plate guide rail 102 provided on the frame 101, so that the top plate 201 can move up and down along the longitudinal direction (height direction) of the frame 101. When the top plate 201 is in the display position, it is located below the blood collection tubes 601. At this time, the label 602 of the blood collection tube 601 can be fully exposed, which facilitates medical staff to collect the information of the label 602 (see...). Figure 7 When the top plate 201 moves upward to the fixed position, the top plate 201 is located at the upper end of the blood collection tube 601, and the restriction effect of the placement hole 202 on the blood collection tube 601 is enhanced (see...). Figure 9 This reduces the possibility of blood collection tube 601 detaching from the tube rack and improves the stability of blood collection tube 601 placement during transportation.

[0028] See Figure 3The working part 301 is fixedly connected to the frame 101. The working part 301 is provided with multiple through holes for the blood collection tubes 601 to pass through. The through holes are circular, and the through holes provided in the working part 301 correspond one-to-one with the multiple placement holes 202 provided in the top plate 201 above. The edge of the through hole provided in the working part 301 is also provided with a first abutment part 302. The blood collection tubes 601 inserted into the placement holes 202 can move downward and be inserted into the through holes provided in the working part 301.

[0029] See Figure 4 , Figure 5 The clamping member 401 also has a through hole for the blood collection tube 601 to pass through. The through hole of the clamping member 401 is an elongated hole, and the through hole of the clamping member 401 is arranged one-to-one with the multiple placement holes 202 provided on the upper top plate 201. The blood collection tube 601 inserted into the placement hole 202 can move downward and be inserted into the through hole of the clamping member 401. The clamping member 401 can move laterally along the frame 101. See [reference needed]. Figure 1 The clamping member 401 is slidably connected to the clamping member guide rail 103 and can move along the length of the frame 101 (see [reference]). Figure 7 ,by Figure 7 The direction described in the text is that the clamping member 401 can move left and right), and the length direction of the through hole provided in the clamping member 401 is parallel to the movement path of the clamping member 401 (see [link]). Figure 5 ).

[0030] See Figure 6 The frame 101 is fixedly connected to a base plate 108 located below the clamping member 401 and the working member 301, supporting the bottom of the blood collection tube 601. The bottom of the blood collection tube 601 can be placed on the upper surface of the base plate 108 through the placement hole 202, the through hole provided in the working member 301 and the clamping member 401. Since the placement hole 202 is arranged longitudinally along the frame 101 and coaxially with the through hole of the working member 301, the blood collection tube 601 can remain vertically positioned after being inserted into the placement hole 202 and the through hole of the working member 301. Alternatively, the base plate 108 can be omitted. (See reference...) Figure 6When the clamping member 401 is located below the working member 301, the hole provided by the clamping member 401 for the blood collection tube 601 to enter is no longer a through hole, but a blind hole, so that the clamping member 401 can support the blood collection tube 601. Of course, the clamping member 401 may also not have a hole, and the blood collection tube 601 is placed directly on the upper surface of the clamping member 401. When the clamping member 401 moves, it slides relative to the upper surface of the clamping member 401. Alternatively, when the clamping member 401 is located above the working member 301, the hole provided by the working member 301 for the blood collection tube 601 to enter is no longer a through hole, but a blind hole, so that the working member 301 can support the blood collection tube 601. Those skilled in the art to which this application pertains can set the setting position of the clamping member 401 and the working member 301 as needed, and set the through hole according to the specific situation.

[0031] See Figure 1 , Figure 6 In one embodiment of this application, the working piece 301 and the clamping piece 401 are spaced apart in the longitudinal direction of the frame 101, and the first abutting part 302 and the second abutting part 402 are disposed between the working piece 301 and the clamping piece 401.

[0032] The clamping member 401 is provided with multiple second abutment portions 402 corresponding to each placement hole 202. The second abutment portions 402 are arranged opposite to the first abutment portions 302 in the transverse direction of the frame 101. A space for the blood collection tube 601 to enter is formed between the first abutment portions 302 and the second abutment portions 402 provided for the same placement hole 202. Since the through hole provided by the clamping member 401 is an elongated hole and the length direction of the through hole provided by the clamping member 401 is parallel to the movement path of the clamping member 401, the blood collection tube 601 in the through hole of the clamping member 401 will not hinder the movement of the clamping member 401 relative to the working piece 301.

[0033] When the second abutment portion 402 of the clamping member 401 moves toward the first abutment portion 302 and the distance between them decreases, the first abutment portion 302 and the second abutment portion 402 can clamp the blood collection tube 601 between them; when the second abutment portion 402 of the clamping member 401 moves away from the first abutment portion 302 and the distance between them increases, the first abutment portion 302 and the second abutment portion 402 no longer clamp the blood collection tube 601 between them, and the blood collection tube 601 can be pulled out from the tube rack, or the blood collection tube 601 can be put into the tube rack and placed between the first abutment portion 302 and the second abutment portion 402.

[0034] When the workpiece 301 is positioned above the clamping member 401, and the second abutment 402 passes through the through hole of the workpiece 301 and is located above the first abutment 302, or when the workpiece 301 is positioned below the clamping member 401 and the second abutment 402 passes through the through hole of the workpiece 301 and is located below the first abutment 302, the second abutment 402 will move relative to the through hole of the workpiece 301. Therefore, the shape of the through hole of the workpiece 301 needs to be set to match the movement trajectory of the second abutment 402, which increases the processing difficulty of the through hole of the workpiece 301. By positioning the first abutment 302 and the second abutment 402 between the workpiece 301 and the clamping member 401, the processing difficulty of the first abutment 302 and the second abutment 402 is much simpler.

[0035] See Figure 1 , Figure 2 The control component 501 is slidably connected to the control component guide rail 104 of the frame 101, and the control component 501 can move in the length direction of the frame 101 to move between a first position and a second position.

[0036] See Figure 1 The top plate 201 is provided with a driven part (protrusion 203) below it. The protrusion 203 protrudes downward. The control member 501 is provided with an active part 502 that cooperates with the driven part. The active part 502 includes a bracket and a rotating roller located on the top of the bracket. The inclined surface of the protrusion 203 gradually slopes towards the second position from its root to its top.

[0037] The control element 501 moves from the first position to the second position (to) Figure 7 When the control member 501 moves to the left, the roller begins to abut against the root of the protrusion 203. The roller gradually approaches the top of the driven part, so that the control member 501 pushes the top plate 201 upward through the roller provided in the active part 502, and finally pushes the top plate 201 to a fixed position.

[0038] The movement path along the control element 501 also includes a transition position, which is located between the first position and the second position; Figure 7 This is a schematic diagram of the control element 501 in the first position in this application. Figure 8 This is a schematic diagram of the control element 501 in this application when it is in the transition position, at which time there is a large gap between the second abutment part 402 and the first abutment part 302.

[0039] When the control member 501 moves from the first position to the second position, and is between the first position and the transition position, the driving part 502 of the control member 501 contacts the driven part of the top plate 201. Along the movement path of the control member 501, the force-applying part 504 of the control member 501 is spaced apart from the force-receiving part 403 of the clamping member 401, and does not contact the force-receiving part 403 of the clamping member 401. At this time, the control member 501 cannot apply force to the clamping member 401 to drive it to move. Figure 7 The direction described in the middle cannot make the second abutment 402 move to the left and approach the first abutment 302. At this time, the first abutment 302 and the second abutment 402 do not clamp the blood collection tube 601.

[0040] When the control member 501 reaches the transition position, the force-applying part 504 of the control member 501 begins to contact the force-receiving part 403, and as the control member 501 continues to move towards the second position (towards... Figure 8 In the direction of the center, the control member 501 moves to the left. The control member 501, through the force-applying part 504 and the force-receiving part 403, drives the clamping member 401 to move to the second position, thereby causing the second abutment part 402 to move closer to the first abutment part 302, until the control member 501 reaches the second position. See Figure 9 The reduced distance between the second abutment 402 and the first abutment 302 allows for radial clamping of the sidewall of the blood collection tube 601. Furthermore, the inner walls of the first abutment 302 and the second abutment 402 can be provided with a silicone or rubber layer to increase friction with the blood collection tube 601 while preventing damage to the tube wall.

[0041] During the transition from the transition position to the second position, the top plate 201 can continue to rise. When the control member 501 reaches the second position, the top plate 201 simultaneously reaches the fixed position. Figure 8 , Figure 9 As shown, the top of the protrusion 203 has a plane parallel to the length direction of the frame 101 and connected to the inclined surface. When the control member 501 reaches the transition position, the top plate 201 can reach the fixed position. At this time, the roller reaches the plane at the top of the protrusion 203, and the control member 501 continues to move to the second position. The roller rolls on the plane and no longer pushes the top plate 201 upward, finally realizing that the top plate 201 is in the fixed position. The control member 501 drives the clamping member 401 to the second position, realizing that the first abutment part 302 and the second abutment part 402 clamp the blood collection tube 601. When the top plate 201 is in the fixed position and the clamping member 401 is in the second position, compared with the way the roller is in the inclined surface of the protrusion 203, the way the roller is in the top plane of the protrusion 203 can make the top plate 201 stably maintain the fixed position during the transfer of the blood collection tube 601.

[0042] See Figure 1 , Figure 9 In one embodiment of this application, a positioning pin 105 is slidably connected to the frame 101. The positioning pin 105 can move in a direction perpendicular to the movement path of the control member 501. The control member 501 is provided with a pin hole 503 for the positioning pin 105 to enter and exit. When the control member 501 reaches the second position, the positioning pin 105 can be inserted into the pin hole 503, thereby keeping the control member 501 in the second position. The clamping member 401 is kept in the second position by the control member 501, and the top plate 201 is kept in a fixed position. When the control member 501 needs to move, the positioning pin 105 is pulled out from the pin hole 503, so that the control member 501 can move relative to the frame 101.

[0043] In one embodiment of this application, the frame 101 is provided with a limiting block 107 at a fixed position to prevent the top plate 201 from moving upward. The limiting block 107 and the control component 501 work together to prevent the top plate 201 from moving up and down during the transfer of the blood collection tube 601. Thus, the top plate 201, located at a fixed position, restricts the blood collection tube 601 by using the placement hole 202 and cooperating with the first abutment part 302 and the second abutment part 402 to clamp the blood collection tube 601, thereby preventing the blood collection tube 601 from detaching from the tube rack during the transfer of the blood collection tube 601.

[0044] Those skilled in the art to which this application pertains will understand that the configuration of the driven part is not limited to the aforementioned protrusion 203 and the driving part 502 including a roller. Alternatively, the driven part may include a roller and a bracket connected to the roller, with the driving part 502 being a protrusion 203. Or, both the driving part 502 and the driven part may be protrusions 203. The inclined surface of the driving part 502 gradually slopes towards a first position from its root to its top, and the inclined surface of the driven part gradually slopes towards a second position from its root to its top. Further details will not be elaborated here.

[0045] When the control unit 501 moves from the second position to the first position, the top of the active part 502 gradually approaches the root of the driven part along the inclined surface of the protrusion 203. Under its own weight, or by means of a top plate spring connected to the frame 101, the top plate 201 in the fixed position causes the top plate spring to undergo elastic deformation. Under the elastic force of the top plate spring, the top plate 201 gradually falls to the display position as the active part 502 and the driven part move along the inclined surface of the protrusion 203, exposing the label 602 of the blood collection tube 601.

[0046] In one embodiment of this application, the frame 101 is provided with a limiting block 107 at the display position to prevent the top plate 201 from continuing to fall. This prevents the top plate 201 from impacting the structure located below the top plate 201.

[0047] The squeezing effect of the force-applying part 504 of the control member 501 moving away from the second position on the force-receiving part 403 towards the second position is weakened, so that the second abutment part 402 can move away from the first abutment part 302. The first abutment part 302 and the second abutment part 402 no longer clamp the blood collection tube 601. At this time, the blood collection tube 601 can be pulled out from the tube rack, or the blood collection tube 601 can be put into the tube rack and placed between the first abutment part 302 and the second abutment part 402.

[0048] Furthermore, the clamping member 401 is also connected to the frame 101 via a spring 106, see [reference needed]. Figure 10 Spring 106 is a tension spring. When the clamping member 401 moves from the transition position to the second position, the tension spring undergoes elastic deformation, generating a force that causes the clamping member 401 to return to the transition position. When the control member 501 returns from the second position to the transition position, the tension spring causes the clamping member 401 to return to the transition position. At this time, spring 106 may not undergo elastic deformation. Of course, spring 106 may also undergo elastic deformation. The clamping member guide rail 103 restricts spring 106 from moving the clamping member 401 towards the first position. Under the combined action of spring 106 and clamping member guide rail 103, the clamping member 401 remains in the transition position. Of course, spring 106 can also be a compression spring, which can push the clamping member 401 towards the first position, but this will not be elaborated further.

[0049] Those skilled in the art to which this application pertains will understand that the clamping member 401 and the control member 501 in this application are not limited to moving along the length direction of the frame 101 as described above, but can also move along the width direction of the frame 101, which will not be elaborated here.

[0050] Those skilled in the art to which this application pertains will understand that the clamping member 401 in this application can also be fixedly connected to the control member 501 and can move with the control member 501 between a first position and a second position. When the clamping member 401 reaches the second position, the second abutting part 402 of the clamping member 401 clamps the blood collection tube 601 with the first abutting part 302 of the working member 301. When the clamping member 401 moves to the first position, the second abutting part 402 gradually moves away from the first abutting part 302, and the blood collection tube 601 can freely enter and exit between the first abutting part 302 and the second abutting part 402. When the clamping member 401 is in the first position, the distance between the second abutting part 402 and the first abutting part 302 is the largest.

[0051] When the clamping member 401 is fixedly connected to the control member 501, the clamping member 401 needs to move from the first position to the second position along with the control member 501. This connection method requires that the two adjacent through holes of the working member 301 be far apart to prevent the second abutment part 402 from moving from one through hole of the working member 301 to the other through hole, thus avoiding motion interference. By setting the control member 501 to have a transition position, and the force-applying part 504 only contacts the force-receiving part 403 of the clamping member 401 when the control member 501 is in the transition position, the movement path of the clamping member 401 is shortened. The clamping member 401 only needs to move between the transition position and the second position, so that the placement holes 202 and the through holes corresponding to each placement hole 202 of the working member 301 can be arranged more densely, and the tube rack can hold more blood collection tubes 601.

[0052] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
