Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to an automatic blood collection tube dispensing device and a blood collection tube labeling device. Background Technology

[0002] Patent CN107150837B discloses a vacuum blood collection tube labeling machine. It uses a sliding chute to load vacuum blood collection tubes, either individually or in multiples using clamps. A robotic arm picks up the tubes and places them into a labeling printer for attaching patient labels. The advantage of this method is its large loading capacity, but the disadvantage is the cumbersome loading operation. Specifically, during loading, the tubes need to be manually placed row by row into the chute of the storage section, with all tubes facing upwards.

[0003] It is evident that while this labeling machine is highly efficient during operation, the pre-operation steps are relatively cumbersome and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic blood collection tube dispensing device and a blood collection tube labeling device, which has the advantages of simple operation, high work efficiency, and no need to consider the orientation of the blood collection tube.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic blood collection tube dispensing device, comprising:

[0006] A storage tank, the bottom of which is provided with a channel and inclined surfaces located on both sides of the channel and guiding towards the channel;

[0007] A loading block, wherein at least one side of the loading block is provided with at least two loading slots, the slot openings being located diagonally above the bottom of the slot; the loading block is movably installed in the storage tank and is capable of driving the loading slots to enter and exit the storage tank via the channel;

[0008] A first driving device drives the loading block to reciprocate in a vertical direction;

[0009] The second driving device drives the paddle to reciprocate along a horizontal straight line.

[0010] The connecting tube bucket has an outlet at its bottom that can only accommodate one blood collection tube.

[0011] When the loading block is in the first position, all the loading slots are located inside the storage tank; when the loading block is in the second position, the loading slots are partially located outside the storage tank and the bottom loading slot is aligned with the lever; when the loading block is in the third position, all the loading slots are located outside the storage tank.

[0012] Furthermore, the storage box is equipped with a baffle, which divides its interior into a receiving cavity for accommodating blood collection tubes. An opening for the blood collection tubes to pass through is formed between the bottom of the baffle and the channel. The loading block is provided with loading grooves on two opposite sides and two side plates on its top surface. When the loading block moves, the side plates always form a sliding seal with the corresponding baffles.

[0013] Furthermore, the loading slots on both sides of the loading block are staggered.

[0014] Furthermore, the first drive device includes a lead screw and a first motor. The lead screw is vertically installed and passes through the storage tank. The loading block is threadedly engaged with the lead screw. The main shaft of the first motor is connected to one end of the lead screw.

[0015] Furthermore, the second drive device includes a second motor, a synchronous belt mechanism, and a rotating shaft. The synchronous belt mechanism is horizontally mounted, with one end connected to the main shaft of the second motor and the other end connected to the rotating shaft. The paddle is mounted on the belt of the synchronous belt mechanism.

[0016] Furthermore, it also includes multiple position detectors that detect the movement positions of the loading block and the paddle, respectively.

[0017] Furthermore, a positioning detector is installed at the outlet of the pipe hopper.

[0018] Furthermore, the first drive device includes a third motor, a crank, and a connecting rod; the main shaft of the third motor is connected to one end of the crank, the other end of the crank is connected to one end of the connecting rod, and the other end of the connecting rod is connected to one side of the loading block.

[0019] The present invention also provides a blood collection tube labeling device, including a body and a tube outlet device disposed within the body, wherein the tube outlet device is an automatic blood collection tube outlet device as described above.

[0020] Compared with the prior art, the beneficial effects of this utility model are: this utility model does not require manual placement when loading blood collection tubes, but simply pours the blood collection tubes directly into the storage box. Automatic loading of blood collection tubes is achieved through a loading block with a lifting mechanism and a loading groove. After loading, the blood collection tubes are transferred to the connecting hopper by a lever, and then the blood collection tubes are output to the next station in a single tube and vertical manner through the guiding action of the outlet at the bottom. It has the advantages of simple operation, high efficiency and large loading capacity. Attached Figure Description

[0029] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1: As Figures 1 to 6 As shown, this utility model provides an automatic tube dispensing device for blood collection tubes, including a storage box 1, a loading block 2, a first driving device 3, a second driving device 4, and a tube hopper 5.

[0031] The bottom of the storage box 1 is provided with a channel 6 and inclined surfaces 7 located on both sides of the channel 6 and guiding the blood collection tubes towards the channel 6. The function of the inclined surfaces 7 is to guide the blood collection tubes in the storage box 1 towards the channel 6, and the inclination angle of the inclined surfaces 7 relative to the horizontal plane is 30°-45°. As a preferred example, a baffle 8 is provided inside the storage box 1, thereby dividing its interior into a receiving cavity 9 for accommodating the blood collection tubes. An opening 10 for the blood collection tubes to pass through is formed between the bottom of the baffle 8 and the channel 6. The top surface of the loading block 2 is provided with two side plates 11. When the loading block 2 moves, the side plates 11 always form a sliding seal with the corresponding baffle 8. This can prevent the blood collection tubes from entering between the two baffles 8 after the loading block 2 descends.

[0032] At least one side of the loading block 2 is provided with at least two loading slots 12. To improve efficiency and loading capacity, two loading slots 12 are provided on each side of the loading block 2, and the opening of the loading slot 12 is located diagonally above the bottom of the slot, so that the blood collection tube can slide completely into the loading slot 12 and cannot slide out. As a preferred embodiment, the loading slots 12 on both sides of the loading block 2 are staggered.

[0033] The loading block 2 is movably mounted in the storage tank 1 via guide rod 13 and linear bearing 14, and can drive the loading slot 12 to enter and exit the storage tank 1 through the channel 6. Clearly, the guide rod 13 is vertically mounted and passes through the storage tank 1, and the loading block 2 is mounted on the guide rod 13 with the linear bearing 14, thus slidingly mounted on the guide rod 13. There are two guide rods 13, symmetrically distributed.

[0034] The first drive device 3 drives the loading block 2 to reciprocate vertically. In a preferred embodiment, the first drive device 3 includes a lead screw 15 and a first motor 16. The lead screw 15 is vertically mounted and passes through the storage tank 1, and the loading block 2 is threadedly engaged with the lead screw 15. The spindle of the first motor 16 is connected to one end of the lead screw 15. The lead screw 15 is located between two guide rods 13. The first motor 16 is mounted on the top of the storage tank 1 via a fixing seat 17. The loading block 2 is threaded or fitted with a nut, thus forming a threaded engagement with the lead screw 15. When the first motor 16 rotates, it can drive the loading block 2 to move up and down.

[0035] The second drive device 4 drives the paddle 18 to reciprocate along a horizontal linear direction. In a preferred embodiment, the second drive device 4 includes a second motor 19, a synchronous belt mechanism 20, and a rotating shaft 21. The synchronous belt mechanism 20 is horizontally mounted, with one end connected to the main shaft of the second motor 19 and the other end connected to the rotating shaft 21. The paddle 18 is mounted on the belt 22 of the synchronous belt mechanism 20. The rotating shaft 21 is fixedly mounted via a bearing seat 23.

[0036] The bottom of the connecting tube hopper 5 is equipped with an outlet 24 that can only accommodate one blood collection tube at a time. When the blood collection tube is pushed out by the pusher 18, it falls into the connecting tube hopper 5, and then the blood collection tube is transported from the outlet 24 to the next station, namely the labeling station. The outlet 24 is vertically set and only allows a single blood collection tube to pass through, thus realizing the individual output of the blood collection tube.

[0037] As a preferred embodiment, to accurately position the moving parts, the device further includes multiple position detectors that detect the movement positions of the loading block 2 and the lever 18, respectively. The position detectors can be limit switches or micro switches. Obviously, for the loading block 2, a limit switch is provided at each of its first, second, and third positions. For the lever 18, a micro switch is provided at each of its starting and ending positions. When a position detector is triggered, the corresponding moving part stops moving or resets.

[0038] Similarly, to determine whether the blood collection tube has been unloaded, a positioning detector is installed at the outlet 24 of the connecting tube 5. The detector can be a photoelectric switch. When a blood collection tube passes through the outlet 24, it will trigger the signal to determine that the current blood collection tube has been unloaded.

[0039] The working process and principle of this utility model

[0040] First, the nurse at the blood collection window places the blood collection tubes into the storage box 1. Then, the device is activated, and the loading block 2 moves up and down several times under the drive of the first drive device 3 to complete initialization. The purpose of initialization is to make the blood collection tubes as parallel as possible after being vibrated during the movement of the loading block 2, thus facilitating subsequent loading. After the loading block 2 is initialized, it returns to its initial position, that is, the first position. At this time, the loading slots 12 are all located in the storage box 1, and the blood collection tubes slide into the loading slots 12.

[0041] Next, the first drive device 3 lowers the loading block 2 to the second position and stops. At this point, the loading slot 12 is partially located outside the storage tank 1, and the bottom loading slot 12 is aligned with the lever 18. The second drive device 4 drives the lever 18 forward. After the lever 18 contacts the blood collection tube, it pushes it towards the connecting tube hopper 5. When the blood collection tube is completely pushed out of the loading slot 12, it falls into the connecting tube hopper 5 in front. Then the blood collection tube is output from the outlet 24 to the next station.

[0042] After the bottom loading slot 12 is unloaded, the lever 18 resets, and the first drive device 3 continues to drive the loading block 2 to descend to the third position. At this time, all loading slots 12 are located outside the storage box 1. The second loading slot 12 is aligned with the lever 18, and then the second drive device 4 drives the lever 18 to complete the unloading operation of the blood collection tubes in the second loading slot 12.

[0043] After all loading slots 12 have been unloaded, loading block 2 is reset under the drive of the first drive device 3 and loads the blood collection tubes again. The above process is repeated until all blood collection tubes have been output.

[0044] Example 2: As Figure 7 As shown, this embodiment differs from Embodiment 1 in that the first driving device 3 in this embodiment includes a third motor, a crank 25, and a connecting rod 26. The main shaft of the third motor is connected to one end of the crank 25, the other end of the crank 25 is connected to one end of the connecting rod 26, and the other end of the connecting rod 26 is connected to one side of the loading block 2. Obviously, the crank 25, the connecting rod 26, and the loading block 2 constitute a crank 25 slider mechanism.

[0045] In this embodiment, the side of the storage tank 1 is provided with a vertical groove 27 extending to the channel 6. Mounting seats 28 are provided on both sides of the loading block 2 for mounting linear bearings 14. The mounting seats 28 are located outside the storage tank 1 and can move within the vertical groove 27. Similarly, the crank 25, connecting rod 26, and guide rod 13 are also provided outside the storage tank 1, with the guide rod 13 slidably connected to the linear bearing 14. When the third motor operates, it can drive the crank 25 and connecting rod 26 to move, thereby driving the loading block 2 to move up and down. The advantage of this driving method is lower cost and easier installation.

[0046] Based on the same inventive concept, the present invention also provides a blood collection tube labeling device, including a main body and a tube outlet device disposed within the main body, wherein the tube outlet device is the automatic blood collection tube outlet device in Embodiment 1 or Embodiment 2.

[0047] Obviously, components requiring fixed installation, such as the storage tank 1, the first drive device 3, the second drive device 4, the guide rod 13, and the connecting pipe hopper 5, are all installed in their corresponding positions on the main body. Furthermore, the electrical components are all controlled by a controller and powered by an external power grid connected via a power supply line. This is a standard procedure and will not be elaborated upon.

[0048] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0049] It should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
