Description

Technical Field

[0001] This invention relates to the field of blood management technology, specifically to an intelligent unmanned blood dispensing device. Background Technology

[0002] A blood dispensing device disclosed in the prior art (CN220316319U) includes a first transmission track, a second transmission track, and at least one operating table unit. The first transmission track is used to transport blood baskets to be dispensed, each containing a blood bag. The second transmission track is used to transport empty baskets. The operating table unit is used to receive the blood baskets to be dispensed on the first transmission track and to transport the empty baskets to the second transmission track. By adding the first and second transmission tracks to the existing operating table, staff only need to dispense blood bags at the operating table unit, eliminating the need to move the blood baskets to be dispensed and the empty baskets, greatly improving the work efficiency of the staff. Multiple operating table units can be set, and the number of operating table units can be flexibly set according to work needs, further improving work efficiency.

[0003] However, the device still has some obvious defects in use: the blood baskets used to transport blood bags usually need to be manually disinfected to ensure that the blood baskets do not contaminate key parts such as tracks, blood collection devices and blood storage chambers during the process of traveling to and from the blood bank. However, the disinfection of blood baskets in the existing technology usually requires manual placement into the disinfection cabinet, and in actual operation, the disinfection steps may be neglected and not disinfected on time, which may cause contamination of the space inside the blood storage chamber. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent unmanned blood dispensing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An intelligent unmanned blood dispensing device includes a blood collection window, on which two sets of blood collection ports are provided; A conveying channel is provided at the blood collection port, and conveying lines are provided on both the inner and outer sides of the conveying channel. A closing baffle is provided on the inner side of the blood collection window in a lifting manner. The blood collection port is opened or closed by the lifting and lowering movement of the closing baffle. Disinfection boxes are installed on both sets of conveyor lines inside the blood collection window. Each disinfection box includes a disinfection box body and an inner lifting door. The disinfection box body is located at both ends of the conveyor line in the conveying direction. The opening of the disinfection box body near the blood collection port abuts against the closed baffle. The inner lifting door is lifted and positioned at the opening on the other side of the disinfection box body. The inner lifting door moves upward without external force, causing the opening of the disinfection box body to open. A linkage lifting drive mechanism is also installed on the disinfection box body. The linkage lifting drive mechanism is used to push the inner lifting door down during the rising of the closed baffle, thereby closing the opening of the disinfection box body on the same side. The inner lifting door is also provided with limit grooves on both sides. The limit grooves are movable and cooperate with the limit blocks that are telescopically set on both sides of the disinfection box. The limit blocks are used to limit and lock the inner lifting door when it moves down to the lowest point, so that the opening on the same side of the disinfection box remains closed. The disinfection chamber is also equipped with a release mechanism on both sides. The release mechanism uses the rotation of the conveyor roller of the conveyor line as power to push the limit block to disengage from the limit groove, thereby causing the inner lifting door to move upward and open the adjacent opening of the disinfection chamber.

[0006] Preferably, the upper part of the closed baffle is movably connected to the telescopic arm of the electric telescopic rod via a hinge, and the fixed end of the electric telescopic rod is fixedly installed on the blood collection window. The telescopic movement of the electric telescopic rod drives the closed baffle to move up and down.

[0007] Preferably, the linkage lifting drive mechanism includes a one-way active ratchet, an active pulley, a driven pulley, and a driven wheel, all rotatably mounted on a wheel frame. The wheel frame is fixedly mounted on the disinfection chamber. The outer ring of the one-way active ratchet meshes with a rack mounted on the inner side of the closed baffle. The inner ring of the one-way active ratchet is coaxially and fixedly connected to the active pulley. The active pulley and the driven pulley are connected by a belt. The driven pulley and the driven wheel are coaxially and fixedly connected. The driven wheel meshes with a toothed groove on the inner lifting door. During the rising of the closed baffle, the inner and outer rings of the one-way active ratchet move synchronously, ultimately driving the driven wheel to rotate. The rotation of the driven wheel pushes the inner lifting door to descend, ultimately causing the limit block to engage with the limit groove.

[0008] Preferably, a pair of spring seats are fixedly installed on the upper part of the inner lifting door, and a traction spring is fixedly installed on the spring seats. The end of the traction spring away from the spring seat is connected to a spring traction frame fixedly installed on the disinfection box. The upward traction of the traction spring causes the inner lifting door to move upward without external force, thereby opening the opening of the disinfection box.

[0009] Preferably, a damping slide bar is also fixedly installed on the spring traction frame, and the telescopic arm end of the damping slide bar is fixedly connected to the spring seat. The setting of the damping slide bar reduces the reset impact of the inner lifting door.

[0010] Preferably, the limiting block is slidably mounted on a pair of auxiliary slide rods, and the limiting block is also connected to the disinfection box body by a locking spring. The locking spring is used to pull the limiting block closer to the limiting groove without external force.

[0011] Preferably, the release mechanism includes a main drive wheel, a reduction transition wheel, and a convex turntable. The main drive wheel is coaxially and fixedly connected to the conveyor roller of the conveyor line. The main drive wheel is connected to the convex turntable through the reduction transition wheel. After the main drive wheel rotates a preset number of times, the protrusions on the convex turntable contact the limit block, thereby pushing it to move away from the limit groove until the limit block disengages from the limit groove. At this time, the inner lifting door is reset under the traction of the traction spring.

[0012] Preferably, the inner lifting door is also equipped with a micro switch inside the disinfection box. When the blood collection box is conveyed inward through the conveyor line, the blood collection box contacts the micro switch and triggers the disinfection mechanism inside the disinfection box to work, thereby disinfecting the blood collection box.

[0013] Preferably, the blood collection window is part of the blood bank's blood storage tank, which is also equipped with a blood storage chamber and an automated blood collection robotic arm, and uses a blood collection box to remove blood bags containing whole blood or blood components.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention features a disinfection mechanism on the conveyor line inside the blood collection port. The inner lifting door of this disinfection mechanism is linked to the closed baffle that is raised and lowered at the blood collection port. The opening process of the inner lifting door is a purely mechanical structure, and it is unlocked during the rotation of the conveyor rollers on the conveyor line. Through the above configuration, the blood collection box can be forcibly disinfected each time it enters the blood collection window. Furthermore, the linkage of the mechanical structure ensures that the disinfection step cannot be skipped, thereby ensuring that the blood collection box is fully disinfected before entering the blood storage bank, guaranteeing that the blood storage bank and the retrieved blood bags are not contaminated.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-7 The present invention provides a technical solution:

[0019] Example 1:

[0020] An intelligent unmanned blood dispensing device includes a blood collection window 1, on which two sets of blood collection ports 2 are provided; A conveying channel is provided at the blood collection port 2. Conveyor lines 3 are provided on both the inner and outer sides of the conveying channel. A sealing baffle 4 is provided on the inner side of the blood collection window 1 in a lifting manner. The blood collection port 2 is opened or closed by the lifting movement of the sealing baffle 4. Disinfection boxes are installed on both sets of conveyor lines 3 inside the blood collection window 1. The disinfection box includes a disinfection box body 5 and an inner lifting door 6. The disinfection box body 5 is located at both ends of the conveyor line 3 in the conveying direction. The opening of the disinfection box body 5 near the blood collection port 2 is against the sealing baffle 4. The inner lifting door 6 is lifted and positioned at the opening on the other side of the disinfection box body 5. The inner lifting door 6 moves upward without external force, causing the opening of the disinfection box body 5 to open. The disinfection box body 5 is also equipped with a linkage lifting drive mechanism. The linkage lifting drive mechanism is used to push the inner lifting door 6 down during the rising of the sealing baffle 4, thereby closing the opening of the disinfection box body 5 on the same side. Limiting grooves are also provided on both sides of the inner lifting door 6. The limiting grooves are in active cooperation with the limiting blocks 7 that are telescopically set on both sides of the disinfection box 5. The limiting blocks 7 are used to limit and lock the inner lifting door 6 when it moves down to the lowest point, so that the opening on the same side of the disinfection box 5 remains closed. The disinfection chamber 5 is also equipped with a release mechanism on both sides. The release mechanism uses the rotation of the conveyor roller 8 of the conveyor line 3 as power to push the limit block 7 to disengage from the limit groove, thereby causing the inner lifting door 6 to move upward and open the adjacent opening of the disinfection chamber 5.

[0021] In this embodiment, the blood collection window 1 is used to isolate the inner and outer parts of the blood bank. The blood collection window 1 is part of the blood bank's blood bank. The blood bank's blood bank is also equipped with a blood storage chamber and an automated blood collection robotic arm. Blood bags containing whole blood or blood components are taken out through blood collection boxes. A blood collection port 2 is opened on the blood collection window 1, through which blood collection boxes are transported in and out. Two conveying channels are opened on the blood collection port 2, and each of the conveying channels is equipped with a conveyor line 3 for transporting blood collection boxes. In order to isolate the inner and outer sides, a closing baffle 4 is raised and lowered on the blood collection window 1 inside the blood collection port 2. The closing baffle 4 is movably connected to the telescopic arm of the electric telescopic rod 9 through a hinge. Thus, the telescopic movement of the electric telescopic rod 9 drives the closing baffle 4 to move up and down synchronously. The above structure is a common structure in the prior art and will not be described in detail here. Unlike existing technologies, this application installs disinfection boxes on both sets of conveyor lines 3, as shown in the attached instruction manual. Figure 1 and 2 To demonstrate the structure of conveyor line 3, only one disinfection box is shown. This disinfection box includes a disinfection box body 5 and an inner lifting door 6. The openings at both ends of the disinfection box body 5 are opened or closed via the lifting inner lifting door 6 and the closing baffle 4, respectively. A linkage lifting drive mechanism is provided on the disinfection box body 5. This mechanism pushes the inner lifting door 6 downwards during the rising of the closing baffle 4, thereby closing the opening of the disinfection box body 5 on the same side, thus maintaining the linkage between their movements. Specifically, the linkage lifting drive mechanism includes a one-way driving ratchet 11, a driving pulley 12, a driven pulley 13, and a driven wheel 14, all rotatably mounted on the wheel frame 10. (Refer to the attached instruction manual.) Figure 6When the sealing baffle 4 is in the closed state, the inner lifting door 6, which is raised and lowered on the other side of the disinfection box 5, is in the open state. During the opening process of the sealing baffle 4, the rack 15 on the sealing baffle 4 pushes the outer ring of the one-way active ratchet 11 to rotate. The rising of the sealing baffle 4 drives the one-way active ratchet 11 to rotate. The rotation of the one-way active ratchet 11 drives the active pulley 12 to rotate. The rotation of the active pulley 12 drives the driven pulley 13 to rotate, which in turn drives the driven wheel 14 to rotate. The driven wheel 14 meshes with the toothed groove 17 of the inner lifting door 6, so it can push the inner lifting door 6 to move downward. The one-way active ratchet 11 only rotates in one direction during the rising process of the sealing baffle 4. After the sealing baffle 4 closes the blood collection port 2, the rack 15 disengages from the outer ring of the one-way active ratchet 11, thereby ensuring that the inner lifting door 6 can move upward smoothly to reset during the subsequent release of the limit.

[0022] Example 2:

[0023] A pair of spring seats 18 are fixedly installed on the upper part of the inner lifting door 6. A traction spring 19 is fixedly installed on the spring seat 18. The end of the traction spring 19 away from the spring seat 18 is connected to the spring traction frame 20 fixedly installed on the disinfection box 5. The upward traction of the traction spring 19 causes the inner lifting door 6 to move upward without the action of external force, thereby opening the opening of the disinfection box 5.

[0024] A damping slide bar 21 is also fixedly installed on the spring traction frame 20. The telescopic arm end of the damping slide bar 21 is fixedly connected to the spring seat 18. The damping slide bar 21 reduces the reset impact of the inner lifting door 6.

[0025] In this embodiment, the connection structure of the inner lifting door 6 is further disclosed. An upward traction force is applied to it by the traction spring 19, so that the inner lifting door 6 moves upward without the action of external force, thereby opening the opening of the disinfection box 5. When the driven wheel 14 rotates and pushes the inner lifting door 6 downward, the inner lifting door 6 does work against the elastic force of the traction spring 19 and stores energy in the traction spring 19, so that the inner lifting door 6 can be pulled back to its original position when the limit is released. At the same time, in order to reduce the impact generated during the resetting process of the inner lifting door 6, a damping slide rod 21 is also fixedly installed on the spring traction frame 20. The setting of the damping slide rod 21 makes the rising process of the inner lifting door 6 stable and slow, thereby ensuring the stability of the device during operation.

[0026] Example 3:

[0027] The limiting block 7 is slidably mounted on a pair of auxiliary slide rods 22. The limiting block 7 is also connected to the disinfection box 5 by a locking spring 23. The locking spring 23 is used to pull the limiting block 7 towards the side closer to the limiting groove without external force.

[0028] The release mechanism includes a main drive wheel 24, a reduction transition wheel 25, and a convex turntable 26. The main drive wheel 24 is coaxially and fixedly connected to the conveyor roller 8 of the conveyor line 3. The main drive wheel 24 is connected to the convex turntable 26 through the reduction transition wheel 25. After the main drive wheel 24 rotates a preset number of times, the protrusions on the convex turntable 26 contact the limit block 7, thereby pushing it to move away from the limit groove until the limit block 7 disengages from the limit groove. At this time, the inner lifting door 6 is reset under the traction of the traction spring 19.

[0029] In this embodiment, a mechanism for limiting and unlocking the inner lifting door 6 is further disclosed. Limiting grooves are provided on both sides of the inner lifting door 6. During the descent of the inner lifting door 6, the locking spring 23 pushes the limiting block 7 into the limiting groove, thereby locking and limiting the inner lifting door 6. At this time, as the sealing baffle 4 on the other side of the disinfection box 5 descends, a space isolated from the external environment is formed inside the disinfection box 5. Blood collection boxes entering this space can undergo forced disinfection through the built-in disinfection device. After disinfection, the limiting block 7 is driven out of the limiting groove by the unlocking mechanism. The specific operation process is as follows: the main drive wheel 24 is coaxially and fixedly connected to the conveying roller 8 of the conveyor line 3. Therefore, the rotation of the conveying roller 8 will drive the main drive wheel 24 to rotate. The rotation of the main drive wheel 24 drives the speed reduction transition wheel 25 and the cam turntable 26 to rotate via the belt 16. The speed reduction transition wheel 25 reduces the rotational speed of the cam turntable 26. Therefore, the speed reduction transition wheel 25 is similar to the structure of a common timer in daily life. Its internal gears reduce the output speed. Since this structure is widely used in timed electric fans, washing machines and timers in the prior art, it will not be described in detail here. After the main drive wheel 24 rotates a certain number of times, the cam turntable 26 can push the limit block 7 out of the limit groove. This process takes about more than 1 minute. Since the operation of the limit release mechanism is driven by the conveyor roller 8 of the conveyor line 3, this process cannot be skipped and plays a role in forced disinfection.

[0030] Example 4:

[0031] The inner lifting door 6 is located inside the disinfection chamber 5 and is also equipped with a micro switch 27. When the blood collection box is transported inward through the conveyor line 3, the blood collection box contacts the micro switch 27 and triggers the disinfection mechanism inside the disinfection chamber 5 to work, thereby disinfecting the blood collection box.

[0032] In this embodiment, a micro switch 27 is installed inside the inner lifting door 6 located inside the disinfection chamber 5. When the blood collection box enters it, the conveyor line 3 needs to keep running and rotating to provide power for opening the inner lifting door 6. During this process, the conveyor roller 8 on the conveyor line 3 will push the blood collection box to move forward, but at the same time, the inner lifting door 6 will obstruct the blood collection box from moving forward. During this process, the blood collection box touches the micro switch 27 installed inside the inner lifting door 6. The micro switch 27 is used as a control switch for the disinfection mechanism to automatically perform disinfection and stop disinfection operations. In this embodiment, vaporized hydrogen peroxide spray is used as a disinfectant. Therefore, multiple vaporization nozzles are set at various positions in the disinfection chamber 5 to ensure sufficient disinfection of various positions inside and outside the blood collection box. The micro switch 27 is used as a control switch to control the nozzles to spray vaporized hydrogen peroxide. It should be noted that the electric mechanism used in this embodiment and the above embodiments is powered by an external power supply.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
