Description

Technical Field

[0001] This utility model relates to medical devices, specifically to a portable blood collection tube holder. Background Technology

[0002] Blood collection racks are used to hold blood collection tubes. Currently, commonly used blood collection racks are similar to test tube racks, both consisting of a frame with multiple insertion holes for the blood collection tubes. In real life, sometimes many blood samples need to be collected. For example, nurses may need to enter a ward to draw blood from multiple patients, and sometimes multiple blood samples need to be drawn from a single patient. Alternatively, blood samples may need to be drawn from multiple people during a physical examination. In these cases, multiple blood collection racks are required. After the blood collection is completed, the multiple blood collection racks containing the blood collection tubes are transported to the designated testing center. Multiple blood collection racks occupy a large area and are inconvenient to transport. Chinese utility model patent CN215277459U discloses a portable blood collection rack that uses connecting rods and fixing mechanisms to achieve a double-layer stacked combination of blood collection racks for easy carrying. However, this portable blood collection rack requires operating multiple connecting rods or fixing mechanisms one by one when stacking the blood collection racks, resulting in inconvenience in use. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned technical problems by providing a portable blood collection tube holder, which can conveniently stack multiple blood collection tubes for easy transport.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A portable blood collection tube holder includes a frame, several pairs of guide rails, and several blood collection tubes. The frame forms a receiving space. The several pairs of guide rails are fixed to the frame at vertical intervals. Each pair of guide rails is arranged opposite to the other in a horizontal direction. The several blood collection tubes are respectively arranged on the several pairs of guide rails. The blood collection tubes can slide in a storage position and a pick-up position via the guide rails. When the blood collection tubes are in the storage position, the several blood collection tubes are stacked and stored in the receiving space. When the blood collection tubes are in the pick-up position, the blood collection tubes are located outside the receiving space.

[0006] Furthermore, each of the guide rails includes a fixed rail and a movable rail. The fixed rail is fixed to the frame, and the movable rail is slidably fitted onto the fixed rail. The blood collection frame is detachably placed on a corresponding pair of movable rails.

[0007] Furthermore, the movable track includes a sliding sleeve that is slidably fitted outside the fixed track and a protruding strip on the top surface of the sliding sleeve. Each blood collection frame has a plug-in fixed at its bottom corresponding to the corresponding guide rail. The plug-in has a slot recessed on the side facing the corresponding guide rail. The blood collection frame is inserted into the corresponding protruding strip through the corresponding slot.

[0008] Furthermore, the connector includes a base plate and two side plates. The base plate is fixed to the bottom surface of the blood collection frame, and the two side plates are fixed to the side of the base plate opposite to the blood collection frame. The two side plates and the base plate surround the slot.

[0009] Furthermore, the connector also includes two guide plates, which respectively fix the side of the two side plates away from the bottom plate, and expand outward from the corresponding side plate in a direction away from the other side plate to form a guide opening communicating with the slot between the two guide plates.

[0010] Furthermore, one end of the pair of movable tracks is fixedly connected by a first connecting rod, and the other end of the pair of movable tracks is fixedly connected by a second connecting rod, with the blood collection frame placed between the first connecting rod and the second connecting rod.

[0011] Furthermore, the fixed track is provided with a stop protrusion, and one end of the inner side of the movable track is provided with an extension limiting protrusion. The extension limiting protrusion can abut against the stop protrusion when the movable track slides out of the receiving space, thereby limiting the position of the movable track extending out of the receiving space.

[0012] Furthermore, a retraction limiting member is fixed at the end of the frame away from the stop protrusion. The retraction limiting member can abut against one end of the movable track when the movable track retracts into the receiving space, thereby limiting the position of the movable track retracted into the receiving space.

[0013] Furthermore, at least one of the guide rails is also provided with a locking element, which includes a spring, a locking pin, and a lever. One end of the spring is fixedly connected to the fixed rail, one end of the locking pin is connected to the other end of the spring, and the lever is fixedly connected to the locking pin. When the blood collection frame is in the storage position, the locking pin abuts against the end face of the movable rail to lock the movable rail. The lever is forced to move the locking pin downward and compress the spring, so that the locking pin disengages from the movable rail.

[0014] Furthermore, the fixed track is provided with a locking groove and a sliding opening. The locking groove extends vertically and penetrates the top surface of the fixed track to form an inlet and outlet. The sliding opening is opened on the side of the fixed track and communicates with the locking groove. The sliding opening extends vertically. One end of the spring is fixedly connected to the bottom of the locking groove. One end of the locking pin is located in the locking groove and connected to the other end of the spring. The other end of the locking pin protrudes out of the locking groove through the inlet and outlet. The lever passes through the sliding opening and one end is fixedly connected to the locking pin.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] 1. The aforementioned portable blood collection tube holder has several pairs of guide rails arranged vertically at intervals along the frame. Multiple blood collection tubes are respectively set on several pairs of guide rails. The guide rails allow the blood collection tubes to slide in a storage position and a pick-up and drop position. When the blood collection tubes are in the storage position, they are stacked and stored in the storage space for easy transport. When the blood collection tubes are in the pick-up and drop position, they are located outside the storage space for easy removal and placement of blood collection tubes from the blood collection tubes.

[0017] 2. The aforementioned portable blood collection tube holder includes a fixed track and a movable track that is slidably mounted on the fixed track. During the process of removing the blood collection holder, the movable track is always supported at the bottom of the blood collection holder, making the movement of the blood collection holder stable and preventing the blood collection tubes from falling off. The blood collection holder can be detachably placed on the corresponding pair of movable tracks. When using it, if the number of blood collection tubes is small, the blood collection holder can be directly removed from the movable track and carried to the blood collection point for use, making it more flexible to use.

[0018] 3. The aforementioned portable blood collection tube holder, when placed on the corresponding pair of movable tracks, prevents the blood collection tube from moving arbitrarily in a direction perpendicular to the movable track by the insertion and engagement of the slot on the blood collection tube with the protrusion of the movable track. The cooperation between the first connecting rod and the second connecting rod also prevents the blood collection tube from moving arbitrarily along the movable track, thereby making the movement of the blood collection tube along the movable track more stable.

[0033] Please see Figure 1 A preferred embodiment of the present invention provides a portable blood collection tube holder 100, comprising a frame 10, several pairs of guide rails 20 and several blood collection frames 30. The several pairs of guide rails 20 are fixed vertically at intervals on the frame 10, and the several blood collection frames 30 are respectively disposed on the several pairs of guide rails 20.

[0034] Please see also Figure 2 and Figure 3 In this embodiment, the frame 10 encloses a receiving space 12 with a side opening 11. A handle 13 is also fixedly connected to the top surface of the frame 10 for easier transport of the portable blood collection tube holder 100. A retraction limiting member 14 is fixed to the side of the frame 10 away from the side opening 11; the retraction limiting member 14 can be a plate, rod, or other structure. Each pair of guide rails 20 is arranged opposite each other in the horizontal direction; please refer to [reference needed]. Figure 6 Each guide rail 20 includes a fixed rail 21 and a movable rail 23. The fixed rail 21 is fixed to the frame 10 and located within the receiving space 12. The movable rail 23 is slidably fitted onto the fixed rail 21. The movable rail 23 can move relative to the fixed rail 21 under force and slide out of the receiving space 12 through the side opening 11. In this embodiment, the movable rail 23 includes a sliding sleeve 231 slidably fitted onto the fixed rail 21 and a protruding strip 232 protruding from the top surface of the sliding sleeve 231. The protruding strip 232 extends along the length direction of the sliding sleeve 231. Please refer to [further details omitted]. Figure 3 and Figure 4In this embodiment, one end of a pair of movable tracks 23 is fixedly connected together by a first connecting rod 24, and the other end of a pair of movable tracks 23 is fixedly connected together by a second connecting rod 25. Specifically, the first connecting rod 24 is perpendicular to the movable track 23, and the opposite ends of the first connecting rod 24 are respectively fixedly connected to one end of the two protrusions 232 near the side opening 11. The second connecting rod 25 is perpendicular to the movable track 23, and the opposite ends of the second connecting rod 25 are respectively fixedly connected to the other end of the two protrusions 232.

[0035] Please see also Figure 7 and Figure 8 The fixed track 21 has a stop protrusion 211. In this embodiment, the stop protrusion 211 is fixed to one end of the fixed track 21 near the side opening 11. The inner end of the movable track 23 has an extension limiting protrusion 234.

The extension limiting protrusion 234 can abut against the stop protrusion 211 when the movable track 23 slides out of the receiving space 12, thereby limiting the position of the movable track 23 extending out of the receiving space 12 and preventing the movable track 23 from detaching from the fixed track 21. When the movable track 23 retracts into the receiving space 12, the end of the movable track 23 away from the side opening 11 can abut against the retraction limiting member 14, thereby limiting the position of the movable track 23 retracted into the receiving space 12 and preventing the movable track 23 from detaching from the fixed track 21.

[0036] Several blood collection racks 30 are respectively set on several pairs of guide rails 20. The blood collection racks 30 can slide in a storage position and a pick-up and put-down position through the guide rails 20: when the blood collection rack 30 is in the storage position, the blood collection rack 30 is stored in the storage space 12; when the blood collection rack 30 is in the pick-up and put-down position, the blood collection rack 30 is outside the storage space 12.

[0037] Please see also Figure 5In this embodiment, the blood collection frame 30 is detachably placed on a pair of corresponding movable rails 23 and located between the first connecting rod 24 and the second connecting rod 25. The structure of the blood collection frame 30 is prior art. For example, a blood collection frame for testing can be found in Chinese Utility Model Patent No. ZL200820224913.1. The main difference is that in this embodiment, a connector 31 is fixed to the bottom of the blood collection frame 30 corresponding to the corresponding guide rail 20. A slot 310 is recessed on the side of the connector 31 facing the corresponding guide rail 20, and the blood collection frame 30 is inserted into the corresponding protrusion 232 through the corresponding slot 310. In this embodiment, the connector 31 includes a base plate 311 and two side plates 312. The base plate 311 is fixed to the bottom surface of the blood collection frame 30, and the two side plates 312 are fixed to the side of the base plate 311 facing away from the blood collection frame 30. The two side plates 312 and the base plate 311 surround to form the slot 310. The connector 31 also includes two guide plates 313. The two guide plates 313 fix the side of the two side plates 312 away from the bottom plate 311 respectively, and expand outward from the corresponding side plate 312 in the direction away from the other side plate 312, thereby forming a guide opening 314 between the two guide plates 313 that communicates with the slot 310.

[0038] Please see also Figure 9 and Figure 10 In this embodiment, a locking element 50 is also provided on one of the pair of guide rails 20. The locking element 50 is used to lock the movable rail 23 when the blood collection frame 30 is in the storage position to prevent the movable rail 23 from accidentally extending out of the receiving space 12. The locking element 50 includes a spring 51, a locking pin 52, and a lever 53. One end of the spring 51 is fixedly connected to the fixed rail 21. Specifically, the fixed rail 21 is provided with a locking groove 212 and a sliding opening 213. The locking groove 212 extends vertically and penetrates the top surface of the fixed rail 21 to form an inlet and outlet 214. The sliding opening 213 is opened on the side of the fixed rail 21 and communicates with the locking groove 212. The sliding opening 213 extends vertically. The spring 51 is housed in the locking groove 212, and one end of the spring 51 is fixedly connected to the bottom of the locking groove 212. One end of the locking pin 52 is connected to the other end of the spring 51. In this embodiment, one end of the locking pin 52 is located in the locking groove 212 and connected to the other end of the spring 51, while the other end of the locking pin 52 protrudes out of the locking groove 212 via the inlet / outlet 214. The lever 53 is fixedly connected to the locking pin 52. In this embodiment, the lever 53 passes through the sliding opening 213 and one end is fixedly connected to the locking pin 52. When the blood collection frame 30 is in the storage position, the locking pin 52 abuts against the end face of the movable track 23 to lock the movable track 23. The lever 53 is forced to move the locking pin 52 downward and compress the spring 51, so that the locking pin 52 disengages from the movable track 23, thereby allowing the movable track 23 to move relative to the fixed track 21 and extend out of the receiving space 12.

[0039] When using the portable blood collection tube holder 100, if multiple blood collection holders 30 need to be carried, firstly, with one hand, push the lever 53 downwards to move the locking pin 52 downwards, causing the locking pin 52 to disengage from the movable track 23 to unlock it. The spring 51 is in a compressed state. With the other hand, apply force to the first connecting rod 24 to move the movable track 23 until the extended limiting protrusion 234 abuts against the stop protrusion 211. At this time, the movable track 23 slides out of the receiving space 12, and the locking pin 52 is pressed by the movable track 23, keeping the spring 51 in a compressed state. Then, place the blood collection holder 30 on the movable track 23, so that the protrusion 232 of the movable track 23 moves along the guide opening 31. 4. Insert the blood collection frame 30 into the slot 310 at the bottom; finally, push the movable track 23 in the direction close to the retraction limit member 14 until one end of the movable track 23 abuts against the retraction limit member 14 on the frame 10. At this time, the blood collection frame 30 moves together with the movable track 23 into the receiving space 12; in addition, the movable track 23 moves to the inside of the locking pin 52 to separate from the locking pin 52. The locking pin 52 is no longer under the pressure of the movable track 23. The elastic restoring force of the spring 51 causes the locking pin 52 to move upward and stop outside the end face of the movable track 23 away from the retraction limit member 14, thereby preventing the movable track 23 and the blood collection frame 30 from accidentally sliding out of the receiving space 12. Repeat the above steps to stack multiple blood collection frames 30 in the receiving space 12 of the bracket for easy carrying.

[0040] Once the portable blood collection tube holder 100 reaches the designated position, during blood collection, the blood collection rack 30 without a blood collection tube can be pulled out of the receiving space 12. The method for pulling out the blood collection rack 30 is the same as described above and will not be repeated here for brevity. After blood collection, place the blood collection tube containing blood into one of the insertion holes of the blood collection rack 30. After the blood collection rack 30 is fitted with a blood collection tube, push the first connecting rod 24 or the blood collection rack 30 towards the retraction limit member 14, causing the blood collection rack 30 to retract into the receiving space 12 of the support 10. The steps for retracting the blood collection rack 30 into the receiving space 12 of the support 10 are the same as described above and will not be repeated here for brevity. After blood collection is completed, the portable blood collection tube holder 100 can be lifted by the handle 13 to transport it to the testing center.

[0041] The aforementioned portable blood collection tube holder 100 has several pairs of guide rails 20 arranged vertically at intervals along the frame body 10. Multiple blood collection racks 30 are respectively arranged on the several pairs of guide rails 20. The guide rails 20 allow the blood collection racks 30 to slide in a storage position and a pick-up and put-down position. When the blood collection racks 30 are in the storage position, they are stacked and stored in the storage space 12 for easy transportation. When the blood collection racks 30 are in the pick-up and put-down position, they are located outside the storage space 12 for easy removal and put-down of blood collection tubes from the blood collection racks 30.

[0042] The aforementioned portable blood collection tube holder 100 includes a guide rail 20 comprising a fixed rail 21 and a movable rail 23 slidably mounted on the fixed rail 21. During the process of removing the blood collection holder 30, the movable rail 23 always supports the bottom of the blood collection holder 30, making the movement of the blood collection holder 30 stable and preventing the blood collection tubes from falling off. The blood collection holder 30 can be detachably placed on the corresponding pair of movable rails 23. When in use, if the number of blood collection tubes is small, the blood collection holder 30 can be directly removed from the movable rail 23 for individual transport to the blood collection site, making it more flexible to use.

[0043] The aforementioned portable blood collection tube holder 100, when the blood collection holder 30 is placed on the corresponding pair of movable tracks 23, can prevent the blood collection holder 30 from moving arbitrarily in a direction perpendicular to the movable track 23 by the insertion and engagement of the slot 310 on the blood collection holder 30 with the protrusion 232 of the movable track 23. The cooperation of the first connecting rod 24 and the second connecting rod 25 can also prevent the blood collection holder 30 from moving arbitrarily along the movable track 23, thereby making the blood collection holder 30 move more smoothly with the movement of the movable track 23.

[0044] The aforementioned portable blood collection tube holder 100 also has a guide port 314 on its connector 31. When the blood collection holder 30 is placed on the corresponding movable track 23, the guide port 314 makes it easier for the slot 310 of the blood collection holder 30 to align with the protrusion 232 on the movable track 23, thus making the connection between the two more convenient.

[0045] The portable blood collection tube holder 100 also includes a locking element 50. When the blood collection holder 30 is in the stored position, the locking pin 52 abuts against the end face of the movable track 23 to lock the movable track 23, preventing the movable track 23 from moving relative to the fixed track 21, thus ensuring that the blood collection holder 30 will not accidentally slide out of the receiving space 12 during transportation. When it is necessary to place a blood collection tube, one hand can push the lever 53 downward to move the locking pin 52 downward, causing the locking pin 52 to disengage from the movable track 23 to unlock it. The other hand can apply force to the blood collection holder 30 or the first connecting rod 24 to move the movable track 23, thereby sliding the blood collection holder 30 out of the receiving space 12 for easy access to and from the blood collection tube. In addition, when the blood collection holder 30 is in the stored position, the pressure applied to the locking pin 52 by the movable track 23 disappears, and the elastic restoring force of the spring 51 can cause the locking pin 52 to move upward to reset and automatically lock the movable track 23. No manual locking is required, making it more convenient to use and preventing the situation where the movable track 23 is forgotten to be locked.

[0046] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
