[0002] Currently, hospitals widely adopt medical logistics transport systems to automate the flow of supplies between departments and floors, significantly improving logistics efficiency and ensuring transport safety. For specimen tubes such as blood collection tubes, the requirement for timely transport is particularly stringent; therefore, pneumatic transport systems are often used. These systems use compressed air to drive the specimen tubes at high speed along pneumatic transport pipelines, greatly improving transport efficiency and fully meeting the need for rapid transport of specimen tubes.

[0003] During the transmission of specimen tubes through pneumatic transfer tubing, precise counting is required at both the sending and receiving ends to achieve accurate control of the transmission process. However, current technology lacks a dedicated counting device that can be efficiently integrated with pneumatic transfer tubing, is compact in structure, and provides accurate counting. Traditional counting devices often suffer from problems such as complex structure, large footprint, or susceptibility to interference leading to miscounting or omissions, making them unsuitable for the efficient and reliable counting needs of hospital logistics systems.

[0004] Therefore, there is an urgent need to develop a dedicated counter that can be seamlessly embedded in pneumatic transmission lines to achieve fast and accurate counting, so as to improve the level of automation control of the entire specimen tube transmission system. Utility Model Content

[0028] like Figures 1 to 6 As shown, the specimen tube counter of this embodiment includes a housing 9 and a support 1, an upper connector 21, a lower connector 22, a roller 3, a motor 4, a counting sensor 5, a reducer 6, and a controller 7 disposed within the housing 9.

[0029] The support body 1 is provided with a counting channel 11 that runs through the upper and lower parts. The inner side of the support body 1 is fitted with a cover plate 12, which covers the counting channel 11, making the counting channel 11 a hollow cavity.

[0030] The upper connector 21 is assembled at the upper end of the support body 1 and is connected to the upper end of the counting channel 11. The lower connector 22 is assembled at the lower end of the support body 1 and is connected to the lower end of the counting channel 11.

[0031] Both the upper connector 21 and the lower connector 22 are connected to the locking cap 23, which is used to connect the pneumatic transmission pipeline. The outer surfaces of the upper connector 21 and the lower connector 22 are provided with external threads, and the inner surface of the locking cap 23 is provided with a threaded hole. The upper connector 21 is threadedly connected to the locking cap 23, and the lower connector 22 is threadedly connected to the locking cap 23.

[0032] The roller 3 is rotatably connected to the support body 1, and part or all of the roller 3 is located within the counting channel 11. The roller 3 is mounted on the axle 31, and the axle 31 is connected to the cover plate 12 via the bearing 32.

[0033] Specifically, one side of the roller 3 protrudes from one side of the counting channel 11, and a space is left between one side of the roller 3 and the other side of the counting channel 11 to allow the specimen tube to pass through.

[0034] The roller 3 has several teeth 30 arranged at intervals along its circumference. The teeth 30 on the circumference of the roller 3 increase the friction with the surface of the specimen tube, ensuring a stable and reliable driving process. This is especially suitable for specimen tubes with smooth surfaces, enhancing the applicability and driving efficiency of the device.

[0035] The motor 4 is located on one side of the support body 1. The output shaft of the motor 4 is connected to the roller 3. The rotation of the output shaft of the motor 4 drives the roller 3 to rotate.

[0036] The motor 4 drives the roller 3 to rotate, which can actively guide and control the specimen tube to be transported in an orderly manner in the counting channel 11, effectively avoiding counting interference caused by multiple tubes running in parallel or congestion, thereby significantly improving the accuracy and reliability of counting.

[0037] Specifically, the reducer 6 is mounted on the cover plate 12, the output shaft of the motor 4 is connected to the input shaft of the reducer 6, and the output shaft of the reducer 6 is connected to the wheel axle 31.

[0038] By setting the reducer 6, the speed and torque output from the motor 4 to the roller 3 are optimized, making the lowering speed of the specimen tube controllable. This ensures both transmission efficiency and provides stable and reliable detection conditions for the counting sensor 5, further ensuring counting accuracy.

[0039] The counting sensor 5 is configured as a grating sensor and is located at the lower end of the counting channel 11. When the specimen tube moves to the lower end of the counting channel 11, the counting sensor 5 senses the specimen tube and counts it.

[0040] The counting sensor 5 performs detection at the lower end of the counting channel 11. Combined with the roller 3 to control the specimen tubes to be lowered one by one, it ensures that the specimen tubes pass through the sensing area of ​​the counting sensor 5 one by one, effectively preventing miscounting or omissions caused by specimen tubes overlapping, having too small a spacing, or passing through at high speed.

[0041] The controller 7 is connected to the counting sensor 5 via a signal cable, and the counting sensor 5 uploads the counting signal to the controller 7.

[0042] The controller 7 is also connected to the display 81 and the speaker 82 via signal cables. The display 81 is exposed from one side of the housing 9. The controller 7 displays the counting data through the display 81, or the controller 7 emits a voice signal of the counting data through the speaker 82.

[0043] By connecting the controller 7 with the display 81 and the speaker 82, the counting data can be displayed in real time and broadcast in voice, making it easier for on-site personnel to intuitively obtain the transmitted quantity information and improving the system's automation level and user interaction experience.

[0044] The specimen tube counter in this embodiment operates as follows: The specimen tubes enter the upper connector 21 from the pneumatic transfer line and continue to move along the counting channel 11. At the position of the roller 3, the rotating roller 3 actively guides the specimen tubes one by one to continue being transported to the lower connector 22. The number of specimen tubes transported to the lower connector 22 per unit time depends on the rotational speed of the roller 3. This ensures that the specimen tubes are placed in a queue and placed to the lower connector 22 one by one, ensuring that each specimen tube passes through the lower end of the counting channel 11. When the specimen tubes move to the lower end of the counting channel 11 and pass through the sensing area of ​​the counting sensor, the counting sensor 5 senses the specimen tubes and counts them, and the counting sensor 5 uploads the counting signal to the controller 7. The controller 7 displays the counting data on the display 81, or emits an audio signal through the speaker 82.

[0045] A specimen tube transport system is provided, wherein the specimen tube transport system is equipped with the specimen tube counter described above in this embodiment, and the upper connector 21 and lower connector 22 of the specimen tube counter are connected to the pneumatic transport pipeline of the specimen tube transport system.

[0046] The present embodiment has now been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the specimen tube counter of this utility model. Of course, the above description is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made under the inventive concept of this utility model using the content of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model and should be protected by this utility model.
