Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an emergency channel mechanical structure for a long-distance pneumatic transmission system. Background Technology

[0002] Hospitals need to draw blood from numerous patients daily for testing. Vacuum tubes are commonly used to draw blood. These tubes need to be transported to the laboratory's testing equipment as quickly as possible. For many emergency patients or those with severe conditions, their blood tubes are often the first to be tested and have a high priority. However, current tube transfer systems transport tubes one at a time. For higher-priority tubes, medical staff must manually operate the system or continue transporting them using the existing system, then manually select them for testing. This easily leads to situations where tubes that should be tested first are not prioritized, delaying the treatment process, slowing down the process, and reducing the efficiency of medical staff. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an emergency channel mechanical structure for a long-distance pneumatic transmission system. It features the advantages of inserting priority test tubes into the existing conveyor line for transport, simple structure and operation, and fast transport speed. It solves the problems of high-priority test tubes being easily missorted or transported without priority distinction during the testing process, thus delaying the test, and the slow speed and reduced work efficiency of medical staff transporting them by themselves.

[0005] (II) Technical Solution

[0006] To achieve the aforementioned goal of inserting priority test tube conveying into the existing conveyor line, with simple structure and operation and high conveying speed, this utility model provides the following technical solution: an emergency passage mechanical structure for a long-distance pneumatic transmission system, including a dial wheel base and a motor base, wherein a dispensing wheel is rotatably disposed between the dial wheel base and the motor base, and a motor is disposed on the motor base, wherein the motor and the dispensing wheel are mechanically connected by transmission.

[0007] The dial wheel is used to place the first test tube, and a pusher is also provided on one side of the dial wheel seat;

[0008] When the first test tube is placed on the dispensing wheel, if there is no second test tube at the bottom of the first test tube, the motor drives the dispensing wheel to rotate, and the first test tube falls and is conveyed; if there is a second test tube at the bottom of the first test tube, the pusher pushes the second test tube out, and the motor drives the dispensing wheel to rotate again, and the first test tube falls and is conveyed.

[0009] Preferably, the motor mount is provided with a through-beam sensor mount, the through-beam sensor mount is provided with a through-beam sensor, and the dial mount is also provided with a through-beam sensor, with the two through-beam sensors positioned opposite each other.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an emergency passage mechanical structure for a long-distance pneumatic transmission system, which has the following advantages:

[0018] The emergency passage mechanical structure of this long-distance pneumatic transport system utilizes the coordinated operation of its various components. In hospitals, blood samples collected from patients need to be transported from the equipment to other departments for testing. These samples have high priority and are urgent, so they must be transported first. First, the first test tube is placed into the sorting wheel through the slot in the test tube limiting plate; at this point, the orientation of the first test tube is not fixed. After placement, two through-beam sensors detect the first test tube sample, and it waits on the sorting wheel. If the second test tube is already present, a vision sensor detects this position. If the second test tube is detected, a pusher pushes it away according to the program settings. When the vision sensor detects no test tube at this position, the emergency passage activates. The motor drives the coupling, which in turn drives the sorting wheel to rotate 1 / 3 of a turn. Based on the slot on the photosensitive film, a photoelectric sensor detects the slot position and rotates the wheel. The first test tube on the sorting wheel will then fall into the original position of the second test tube, and the pusher will then push the first test tube into the transport path. If there is no second test tube, the motor will directly drive the dispensing wheel to rotate, causing the first test tube to fall and be pushed out. This method features a low failure rate, high speed, and simple structure. It achieves the effect of inserting priority test tube conveying into the existing conveyor line, with simple structure and operation, and high conveying speed. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 An emergency passage mechanical structure for a long-distance pneumatic transmission system includes a dial seat 9 and a motor seat 7. A dispensing wheel 13 is rotatably mounted between the dial seat 9 and the motor seat 7. A motor 6 is mounted on the motor seat 7 and drives the dispensing wheel 13 to rotate. The motor 6 and the dispensing wheel 13 are mechanically connected. The dial seat 9 provides support for the dispensing wheel 13, enabling it to rotate between the dial seat 9 and the motor seat 7, and together with the motor seat 7, forms the framework of the entire emergency transport passage structure.

[0026] The dispensing wheel 13 is used to place the first test tube 4. The cross-section of the dispensing wheel 13 is "Y" shaped, and the three wheels are spaced 120° apart. Each time the first test tube 4 is placed, the first test tube 4 will be clamped between the two sides.

[0027] A pusher 16 is also provided on one side of the dial seat 9. The pusher 16 is used to push the test tubes (including the second test tube 15 and the first test tube 4 falling from above) that are sensed by the vision sensor 11.

[0028] When the first test tube 4 is placed on the sorting wheel 13, if there is no second test tube 15 at the bottom of the first test tube 4, it means that there are no other test tubes in the conveying route. At this time, the first test tube 4 placed in the sorting wheel 13 is directly driven by the motor 6 to fall to the bottom and is pushed away by the push head 16. At this time, the first test tube 4 has the highest priority.

[0029] If there is a second test tube 15 at the bottom of the first test tube 4, the first test tube 4 has a higher priority and needs to replace the position of the second test tube 15. The pusher 16 pushes out the second test tube 15, and the motor 6 drives the dial wheel 13 to rotate. The first test tube 4 falls down, and at this time the first test tube 4 replaces the position of the second test tube 15. The priority of the first test tube 4 increases, and it is then sent away for inspection by the pusher 16.

[0030] A through-beam sensor mount 10 is mounted on the motor mount 7, and a through-beam sensor 5 is mounted on the through-beam sensor mount 10. A through-beam sensor 5 is also mounted on the dial mount 9. The two through-beam sensors 5 are positioned opposite each other. The two through-beam sensors 5 work together, with one being the transmitter and the other the receiver. When an object, such as the first test tube 4, enters between the two through-beam sensors 5, it will block the signal, thereby triggering the sensor's sensing mechanism to detect whether the first test tube 4 has reached the designated position. This provides a position feedback signal to the entire transportation system, so that the control system can determine subsequent operations based on the detection results, such as whether to rotate the dial wheel 13 or to transport the first test tube 4.

[0031] A vision sensor 11 is installed on the lower side of the first test tube 4. The vision sensor 11 is used to detect the presence of the second test tube 15. The vision sensor 11 uses optical imaging and image processing technology to visually monitor the area below the first test tube 4. By analyzing the acquired image information, it determines whether the second test tube 15 exists in the area and converts the detection result into an electrical or digital signal output. This allows the system to decide whether to allow the first test tube 4 to fall and be transported directly, or to push the second test tube 15 aside first and then allow the first test tube 4 to fall and be transported, based on the presence of the second test tube 15. This enables accurate handling of different situations, ensures the correct execution of the priority transport process for the first test tube 4, and improves the intelligence and accuracy of the entire transportation system.

[0032] In this patent, the mechanical transmission connection between the motor 6 and the shift wheel 13 is a coupling 12. However, this mechanical transmission connection also includes other alternative connection methods that those skilled in the art can conceive of, such as gears or drive belts, which are not shown in this embodiment. The motor 6 is equipped with a coupling 12, and the motor 6 is fixedly connected to one end of the shift wheel 13 via the coupling 12. The other end of the shift wheel 13 is equipped with a bearing 14, and the shift wheel 13 is rotatably mounted on the shift wheel seat 9 via the bearing 14. The motor shaft of the motor 6 is connected to the shift wheel 13 via the coupling 12, thereby driving the shift wheel 13 to rotate. The other end of the shift wheel 13 rotates and is supported on the shift wheel seat 9 via the bearing 14.

[0033] A photosensitive film 2 is mounted on one end of the shift wheel 13 extending from the shift wheel seat 9. The photosensitive film 2 has three evenly distributed slits. When the shift wheel 13 rotates the photosensitive film 2, the slits pass sequentially through the photoelectric sensor 1. Light emitted by the photoelectric sensor 1 can pass through the slits, while other parts of the photosensitive film 2 block the light, thus creating a change in light transmission. The three slits on the photosensitive film 2 correspond to the "Y"-shaped structure of the shift wheel 13, converting the rotational motion of the shift wheel 13 into detectable and recognizable light signal changes. This provides the system with information on the rotational position and angle of the shift wheel 13, ensuring that the shift wheel 13 rotates only 120° at a time. At this point, the first test tube 4 located on the shift wheel 13 falls into the lower conveyor channel, awaiting ejection by the pusher head 16.

[0034] A test tube limiting plate 3 is fitted between the dial seat 9 and the motor seat 7 to protect and limit the first test tube 4, preventing it from deviating from its position in the dial wheel 13 during placement. The test tube limiting plate 3 is provided with a slot 17, through which the first test tube 4 can be placed on the dial wheel 13.

[0035] Working Principle: After blood collection from patients in the hospital, samples need to be transported from the equipment to other departments for testing. These samples have high priority and are urgent, so they need to be transported first. First, the first test tube 4 is placed into the dispensing wheel 13 through the slot in the test tube limiting plate 3. At this point, the orientation of the first test tube 4 is uncertain. After placement, two through-beam sensors 5 sense the sample in the first test tube 4, which waits on the dispensing wheel 13. If the second test tube 15 is already present, the vision sensor 11 detects this position. If the second test tube 15 is detected, the pusher 16 pushes it away according to the program settings. When the vision sensor 11 detects no test tube at this position, the emergency channel above activates. The motor 6 drives the coupling 12, which in turn drives the dispensing wheel 13 to rotate 1 / 3 of a turn. The photosensitive sensor 1 senses the position of the slot 17 on the photosensitive film 2 and rotates it accordingly. The first test tube 4, located on the dispensing wheel 13, will then fall into the position previously occupied by the second test tube 15. The pusher head 16 will then push the first test tube 4 into the conveyor. If there is no second test tube 15, the motor 6 will directly drive the dispensing wheel 13 to rotate, causing the first test tube 4 to fall and be pushed out. This method features a low failure rate, high speed, and simple structure. It achieves the effect of inserting priority test tube conveying into the existing conveyor line, with simple structure and operation, and high conveying speed.
