Description

Technical Field

[0001] The invention belongs to the technical field of pneumatic transmission, and in particular relates to a pneumatic transmission system. Background Art

[0002] The hospital pneumatic pipeline logistics transmission system integrates advanced modern communication technology and optomechanical integration technology. It connects various departments of the hospital, such as outpatient department, medicine, operating room, laboratory, blood bank, medical technology, inpatient nurse stations, and central supply room, closely together through a dedicated pipeline, comprehensively solving the problem of automatic distribution of hospital logistics.

[0003] The existing pneumatic pipeline logistics transmission system is composed of air compressors, pipelines, pipeline reversers, etc. Its basic purpose is to transport goods. The working principle is that the air compressor extracts and compresses air as power. However, the existing air compressor not only occupies a large area, but also has strong noise. Long-term work in a noisy environment will cause hearing loss and mental anxiety for medical staff. Therefore, a separate room is required for storage, and it cannot be placed directly in places such as nurses' stations. When medical staff need to transport test tubes, they still need to move the test tubes to the pneumatic transmission system near the air compressor. Summary of the invention

DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] Embodiment 1: Figure 1-Figure 6 , Figure 8-Figure 13 As shown, the pneumatic transmission system includes a shell 1 and a fan 2. The shell 1 is provided with a first pipe inlet 3 for the test tube to enter and a first pipe outlet 4 for the test tube to leave. At least one launching device 5 for launching the test tube is provided in the shell 1. The fan 2 is connected to the launching device 5 through an air pipe, and the launching device 5 is connected to a conveying pipeline 7 for conveying the test tube.

[0033] To elaborate further, the fan 2 is arranged in the shell 1, and the fan 2 is provided with a soundproof cover 50 for sound insulation. The soundproof cover 50 performs the first noise reduction on the fan 2, and then reduces the noise through the shell 1. The double noise reduction can reduce the impact of the fan 2 noise on medical staff, ensuring that the fan 2 noise in rooms such as the nurse station and the blood drawing room is at a lower decibel.

[0034] In further detail, the housing 1 is provided with a transfer device 6 for moving the test tube entering from the first pipe inlet 3 to the launching device 5, the transfer device 6 includes a rubbing machine 8, a moving device 9 and a turntable distribution device 10, the rubbing machine 8 is connected to the first pipe inlet 3, the two ends of the moving device 9 are respectively connected to the rubbing machine 8 and the turntable distribution device 10, the turntable distribution device 10 is connected to the launching device 5, the rubbing machine 8 is used to move the test tube from the first pipe inlet 3 to the moving device 9, the moving device 9 is used to move the test tube to the turntable distribution device 10, the turntable distribution device 10 distributes the test tube to different launching devices 5, the rubbing machine 8 includes a shell 11 and a plurality of lifting plates 12 arranged inside the shell 11, and the shell 11 is provided with a guide slope 1 for guiding the test tube 3. Multiple lifting plates 12 are arranged in a stepped shape. The lifting plates 12 can reciprocate in the vertical direction of the shell 11 to lift the test tube on the lower lifting plate 12 to the end surface of the upper lifting plate 12. A limiting inclined surface 14 is arranged above the lifting plate 12. When the test tube enters the rubbing machine 8 from the first pipe inlet 3, it first moves to the lowest end through the guide inclined surface 13, and then the lifting plate 12 at the bottom rises to drive the test tube to move to the adjacent lifting plate 12. This step is repeated until the test tube moves to the highest lifting plate 12 and enters the moving device 9. The limiting inclined surface 14 is arranged to cooperate with the adjacent lifting plate 12 to form a limiting groove for limiting the test tube, which can ensure that the test tube will not move in the horizontal direction when it rises, causing the test tube to fall.

[0035] To further explain, the mobile device 9 includes a support rail 15, an electric telescopic rod 16 arranged on the rubbing machine 8, and a push plate 17 arranged on the electric telescopic rod 16.

[0041] Embodiment 2: Figure 7 As shown, the difference between this embodiment and the first embodiment lies in the position of the fan 2. The fan 2 is arranged outside the shell 1. The fan 2 is provided with a soundproof cover 50 for sound insulation. The shell 1 is provided with a makeshift hole 49 for the air supply pipe to enter. The fan 2 is arranged outside the shell 1 to facilitate subsequent maintenance.
