Abstract
Description
Technical Field
[0001] This invention relates to the field of pneumatic logistics technology, specifically a pneumatic logistics transport system for medical institutions. Background Technology
[0002] In hospitals, a large number of items are transported between different departments and buildings every day, including prescriptions, test reports, medicines, laboratory samples, and diagnostic equipment. These items are mostly small and lightweight, but numerous. Traditional transportation relies on manual transport, which has significant drawbacks: manual transport increases patient flow, making hospitals more crowded; it consumes elevator resources, increasing patient waiting times; it takes a long time, increasing patient waiting times; and it requires hiring dedicated personnel, increasing hospital human resource costs. These drawbacks of traditional hospital logistics are severely hindering hospital development. Pneumatic pipeline logistics transport systems offer a good solution to these problems. When sending items, simply place them at the receiving station, enter the address, and press a button. The items will then travel through a dedicated pipeline to their destination within seconds, with transport time measured in seconds. This significantly improves the efficiency of internal hospital logistics.
[0003] However, when using existing pneumatic tube transport devices, the transport bottle falls directly into the collection box after being transported to the target workstation. Due to the height difference between the collection box and the workstation, and the lack of a buffer protection device inside the collection box, the transport bottle is easily damaged when it falls from the workstation into the collection box. If the transport bottle contains the patient's blood or urine samples, the blood or urine samples can easily leak out of the test tube, contaminating the samples and rendering them unusable. Doctors then need to resample the patient, causing significant inconvenience to both medical staff and patients.
[0004] To address the aforementioned issues, this application proposes a pneumatic transport system for medical institutions. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a pneumatic tube transport system for medical institutions, thereby solving at least one of the problems raised in the background art and making the use of pneumatic tube devices more convenient.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a pneumatic transport system for medical institutions, comprising a workstation, a pipe fixedly connected to the top of the workstation, a pipe fixedly connected to one side of the bottom of the workstation, and a discharge pipe fixedly connected to the other side.

[0008] Preferably, the limiting assembly includes a mounting shell fixedly connected to the bottom of the track. The mounting shell matches the collection box. A sliding cavity is provided on the top of one side of the collection box. A limiting block is slidably connected inside the sliding cavity. Multiple telescopic rods are fixedly connected to the inner wall of the sliding cavity. The other end of the telescopic rod is fixedly connected to the limiting block. A second spring is sleeved on the outer wall of the telescopic rod. One end of the second spring is fixedly connected to the inner wall of the sliding cavity, and the other end is fixedly connected to the limiting block. A limiting groove matching the limiting block is provided on the inner wall of the mounting shell. A push block is slidably connected inside the limiting groove. One side of the push block abuts against the limiting block, and a threaded rod is rotatably connected to the center of the other side. The other end of the threaded rod passes through the mounting shell and is threadedly connected to the mounting shell.

[0009] Preferably, casters are fixedly connected to the four corners at the bottom of the collection box.
[0010] Preferably, an inclined plate is fixedly connected to the bottom of the inner wall of the collection box, and a sponge pad is fixedly connected to the top of the inclined plate.

[0016] In this pneumatic logistics system for medical institutions, after the transport bottle is transported to the target workstation, it falls into the discharge pipe and slides to the discharge chute. The bottle then slides out of the pipe through the chute. A buffer component inside the discharge pipe provides good cushioning protection. After exiting the pipe, the bottle rolls on a track. When it reaches the bottom of a rotating plate, the plate rotates downwards under the bottle's gravity, causing it to fall into a collection box. This allows for the collection of multiple bottles. When medical staff are busy, the bottles can be stored in the collection box for centralized processing, effectively improving the practicality of the pneumatic logistics device.

[0028] 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.
[0029] Please see Figure 1-10 A pneumatic transport system for medical institutions includes a workstation 1. A pipe 2 is fixedly connected to the top of the workstation 1. The pipe 2 is fixedly connected to one side of the bottom of the workstation 1, and a discharge pipe 3 is fixedly connected to the other side. A discharge trough 4 is opened on the outer wall of the discharge pipe 3. A buffer assembly is slidably connected to the inside of the discharge pipe 3 on one side of the discharge trough 4. A track 5 is fixedly connected to the bottom of the discharge trough 4. A hinge 29 is fixedly connected to the lower end of the track 5. A rotating plate 6 is fixedly connected to the other end of the hinge 29. A torsion spring 23 is fixedly installed inside the hinge 29. An arc plate 7 is fixedly connected to the end of the rotating plate 6 away from the hinge 29. A collection box 8 is connected to the bottom of the track 5. A limit assembly is fixedly connected to the bottom of the track 5.
[0030] Specific working principle and implementation method: According to existing technology, when the pneumatic tube transport device is in use, after the transport bottle is transported to the target workstation 1, it falls directly into the collection box 8. Because there is a certain height difference between the collection box 8 and the workstation 1, and because there is no cushioning protection device inside the collection box 8, the transport bottle is easily damaged when it falls from the workstation 1 into the collection box 8. If the transport bottle contains patient blood or urine samples, these samples can easily leak out, contaminating the samples and rendering them unusable. Doctors then need to resample the patient, causing significant inconvenience to both medical staff and patients. Therefore, the technical problem mentioned in the background art exists. The above-designed solution can solve the above problems. After the transfer bottle is transported to the target workstation 1 through the pneumatic tube transport system of the medical institution, the transfer bottle will fall into the discharge pipe 3. The transfer bottle will slide inside the discharge pipe 3 to the discharge trough 4 and slide out of the discharge pipe 3 through the discharge trough 4. The buffer component set inside the discharge pipe 3 can provide good cushioning protection for the transfer bottle. After the transfer bottle slides out of the discharge pipe 3, it will roll on the track 5. When it rolls to the lower end of the turntable 6, the turntable 6 will rotate downward under the gravity of the transfer bottle, so that the transfer bottle falls into the collection box 8, thereby realizing the collection of the transfer bottle. Moreover, the collection box 8 can hold multiple transfer bottles. When medical staff are busy, the transfer bottles can be stored in the collection box 8, so that medical staff can handle the transfer bottles in the collection box 8 at the same time, thereby effectively improving the practicality of the pneumatic tube transport device.
[0031] like Figure 4 As shown, the buffer assembly includes a buffer plate 9. The discharge pipe 3 is slidably connected to the buffer plate 9 on one side of the discharge trough 4. A damping rod 10 is fixedly connected to one end of the inner wall of the discharge pipe 3, and the other end of the damping rod 10 is fixedly connected to the buffer plate 9. A first spring 11 is sleeved on the outer wall of the damping rod 10. One end of the first spring 11 is fixedly connected to one end of the inner wall of the discharge pipe 3, and the other end is fixedly connected to the buffer plate 9. A rubber pad 27 is fixedly connected to the side of the buffer plate 9 near the discharge trough 4. When the transfer bottle falls from inside the workstation 1 to the discharge trough 4... After entering the material pipe 3, the transfer bottle will slide inside the discharge pipe 3. When the transfer bottle slides to the discharge chute 4, the transfer bottle will squeeze the buffer plate 9, thereby causing the damping rod 10 and the first spring 11 to contract, thus achieving the deceleration effect on the transfer bottle. When the speed of the transfer bottle inside the discharge pipe 3 drops to zero, the transfer bottle will slide onto the track 5 through the discharge chute 4. In summary, the device plays a good role in buffering and protecting the transfer bottle. The rubber pad 27 set on one side of the buffer plate 9 can further protect the transfer bottle.
[0032] like Figure 2 and Figure 6As shown, the limiting assembly includes a mounting shell 12 fixedly connected to the bottom of the track 5. The mounting shell 12 matches the collection box 8. A sliding cavity 13 is provided on the top of one side of the collection box 8. A limiting block 14 is slidably connected inside the sliding cavity 13. Multiple telescopic rods 15 are fixedly connected to the inner wall of the sliding cavity 13. The other end of the telescopic rod 15 is fixedly connected to the limiting block 14. A second spring 16 is sleeved on the outer wall of the telescopic rod 15. One end of the second spring 16 is fixedly connected to the inner wall of the sliding cavity 13, and the other end is fixedly connected to the limiting block 14. A limiting groove 17 matching the limiting block 14 is provided on the inner wall of the mounting shell 12. A push block 18 is slidably connected inside the limiting groove 17. One side of the push block 18 abuts against the limiting block 14, and a threaded rod 19 is rotatably connected to the center of the other side. The other end of the threaded rod 19 passes through the mounting shell 12 and is threadedly connected to the mounting shell 12. A screw rod is fixedly connected to the end of the threaded rod 19 extending out of the mounting shell 12. Button 20: When the transfer bottle rolls from the track 5 into the collection box 8 and the collection box 8 is full, turning the knob 20 will rotate the threaded rod 19. The rotation of the threaded rod 19 will push the push block 18 towards the collection box 8, thereby pushing the limiting block 14 into the sliding cavity 13. When the limiting block 14 disengages from the limiting groove 17, the collection box 8 can be removed from below the track 5, making it more convenient for medical staff to centrally process the transfer bottles inside the collection box 8. When medical staff need to install the collection box 8, they insert one side of the top of the collection box 8 into the installation shell 12. During the insertion process, the inner wall of the installation shell 12 will squeeze the limiting block 14 to move it into the sliding cavity 13. When it is inserted to a certain extent, the limiting block 14 will pop out under the action of the telescopic rod 15 and the second spring 16 and engage with the limiting groove 17. The device can then be used normally and has higher stability during use.
[0033] like Figure 2 As shown, casters 26 are fixedly connected to the four corners of the bottom of the collection box 8. With the casters 26 at the bottom of the collection box 8, when the transfer bottle inside the collection box 8 is full, the knob 20 is turned to make the limiting block 14 disengage from the limiting groove 17, and the collection box 8 can be moved by pulling. The advantage of this setting is that it is easier and more convenient for medical staff to transfer the collection box 8, thus making the device more practical.
[0034] like Figure 2As shown, a ramp 24 is fixedly connected to the bottom of the inner wall of the collection box 8, and a sponge pad 25 is fixedly connected to the top of the ramp 24. After the transfer bottle falls from the turntable 6 into the collection box 8 through the ramp 24 at the bottom of the inner wall of the collection box 8, the transfer bottle will roll to the bottom of the collection box 8 through the ramp 24 at the bottom of the collection box 8. The advantage of this design is that when multiple transfer bottles fall into the collection box 8, the transfer bottles will be arranged in an orderly manner inside the collection box 8. This not only effectively prevents the transfer bottles from colliding and causing damage, but also makes it more convenient for medical staff to sort the transfer bottles inside the collection box 8 later. The sponge pad 25 at the top of the ramp 24, due to the soft texture of the sponge material, can further protect the transfer bottle.
[0035] like Figure 7 As shown, guide blocks 21 are fixedly connected to both sides of the push block 18, and guide grooves 22 matching the guide blocks 21 are opened on the inner wall of the limiting groove 17. When the push block 18 slides inside the limiting groove 17, the guide blocks 21 on both sides of the push block 18 and the guide grooves 22 opened on the inner wall of the limiting groove 17 can play a good role in limiting and guiding the push block 18 when it slides inside the limiting groove 17, thereby making the push block 18 more stable when it slides inside the limiting groove 17, and effectively preventing the push block 18 from sliding out of the limiting groove 17, thus effectively ensuring the normal operation of the device.
[0036] like Figure 2 As shown, the highest point of the two side plates of the collection box 8 is not higher than the lowest point of the rotating plate 6. When the transfer bottles inside the collection box 8 are full, the collection box 8 needs to be pulled out from the bottom of the track 5, so that people can easily sort out the transfer bottles inside the collection box 8. By setting the highest point of the two side plates of the collection box 8 to be no higher than the lowest point of the rotating plate 6, it is more convenient for medical staff to pull the collection box 8 outward, and the rotating plate 6 and the track 5 will not affect the pulling out of the collection box 8, thus making the use of the device more convenient.
[0037] like Figure 6 As shown, the knob 20 has an irregular shape, and the outer wall of the knob 20 is covered with a protective sleeve. When people turn the knob 20, the threaded rod 19 rotates. By making the knob 20 irregularly shaped, it is easier for people to turn the knob 20. The anti-slip sleeve on the outer wall of the knob 20 can effectively increase the friction between medical staff and the outer wall of the knob 20, preventing people from slipping when turning the knob 20. This not only makes it more convenient and easier for people to turn the knob 20, but also makes their hands more comfortable.
[0038] like Figure 1As shown, a handle 28 is fixedly connected to one side of the collection box 8, and the outer wall of the handle 28 is covered with an anti-slip sleeve. When the transfer bottles inside the collection box 8 are full, medical staff need to pull the collection box 8 out from the bottom of the track 5 to facilitate the handling of the transfer bottles inside the collection box 8. Through the handle 28 on one side of the collection box 8, medical staff can more easily transfer the collection box 8 by pulling the handle 28. The anti-slip sleeve on the outer wall of the handle 28 can effectively increase the friction between people's hands and the handle 28, prevent people from slipping when pulling the collection box 8, and make people's hands more comfortable when holding the handle 28.
[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
