A bin door 6 is movably connected below the collection bin 3.

[0027] The collection bin 3 is set to receive specimens and collect blood sample specimens. When the specimens enter the collection bin 3 through the receiving joint 2, they first come into contact with the deceleration curtain assembly. The deceleration curtain assembly blocks the specimen test tubes entering the collection cavity 4, plays a buffering role for the specimens, and can effectively reduce the impact of the specimen test tubes. The specimen test tubes will drive the deceleration curtain assembly to move together and slide along the deceleration curtain assembly and fall to the bottom of the collection bin 3, and then the deceleration curtain assembly resets; the counting component 5 on the receiving joint 2 is set to detect and count, so as to realize real-time counting of the specimen test tubes during receiving and ensure the accuracy and reliability of the transmitted quantity.

[0028] Specifically, a connection hole is arranged on the outer shell 1 for connecting the pneumatic transmission pipeline and the receiving joint 2. The bin door 6 seals the collection bin 3 to ensure airtightness and ensure that the collection bin 3 reaches a negative pressure state in the closed state to receive specimens. The counting component 5 can adopt common counting devices in the prior art, such as counting sensors.

[0029] This application is mainly used for sample reception and counting in a negative pressure blood sample transmission system, and unloads the received samples; the application scope of this application includes but is not limited to blood sample test tube reception, and can also be used for the reception of other sample test tubes.

[0030] In the specimen pneumatic transmission and reception device of this embodiment, a collection box 7 is arranged inside the housing 1. The collection box 7 is located below the collection bin 3, and a guiding channel is provided between the collection box 7 and the bin door 6.

[0031] The guiding channel and the collection box 7 are provided to collect the specimens received by the collection bin 3, preventing insufficient space in the collection chamber 4; the guiding channel is provided to ensure that the specimen test tube can guide the specimens dropped from the bin door 6 during unloading by the receiving mechanism into the collection box 7, avoiding specimen loss.

[0032] In the specimen pneumatic transmission and reception device of this embodiment, two guiding plates 8 are symmetrically installed on the inner wall of the housing 1. The two guiding plates 8 are inclined to form the guiding channel. When the bin door 6 is opened, the sample slides out of the collection bin 3 and falls into the collection box 7 through the guiding of the guiding plates 8.

[0033] Preferably, a buffer layer is provided on the surface of the guiding plate 8. The size of the buffer layer is larger than that of the guiding plate 8, and the end of the buffer layer away from the inner wall of the collection bin 3 is located inside the collection box 7, that is, extends into the interior of the collection box 7.

[0034] The buffer layer is provided to buffer and shock-absorb the specimens unloaded from the receiving mechanism, avoiding direct contact and collision between the specimens and the guiding plate 8. The size of the buffer layer is larger than that of the guiding plate 8, ensuring that the buffer layer covers the guiding plate 8, guaranteeing the buffer effect, and improving the stability of specimen reception and collection.

[0035] Preferably, the buffer layer is made of shock-absorbing and sound-absorbing materials to reduce the vibration of the specimen test tube during sliding.

[0036] In the specimen pneumatic transmission and reception device of this embodiment, the deceleration curtain assembly includes a deceleration curtain 9 and a fixing plate. The deceleration curtain 9 is connected to the collection bin 3 through the fixing plate. The deceleration curtain 9 is located at the top of the collection bin 3 and corresponds to the receiving joint 2.

[0037] The deceleration curtain 9 is provided to block the specimen test tube, avoiding collision between the specimen and the inner wall of the collection bin 3, and realizing stable reception of the specimen test tube. The length of the deceleration curtain 9 and the distance between the deceleration curtain 9 and the receiving joint 2 are set according to the length of the specimen test tube to ensure that when the specimen test tube enters the collection chamber 4 through the receiving joint 2, it can contact the deceleration curtain 9 to achieve the deceleration and buffer effect.

The sealing piece 10 is provided. When the collection bin 3 is in the closed state, the bin door 6 compresses the sealing piece 10, thereby further ensuring the airtightness.

[0042] Preferably, the material of the sealing piece 10 can be rubber, which can ensure the sealing effect and further buffer and shock-absorb the specimen test tube falling along the deceleration curtain 9.

[0043] In the specimen pneumatic transmission and reception device of this embodiment, the two sides of the bin door 6 are respectively connected to the output ends of the push rod motors 11.

[0046] The baffles 12 are provided to block the two sides of the bin door 6 and separate the push rod motors 11 from the collection bin 3. When the bin door 6 is opened, it avoids the specimen test tube getting stuck between the push rod and the bin door 6. The position sensor 13 is set to detect the position of the baffle 12 and indirectly detect whether the bin door 6 is reset, so as to ensure the airtightness of the collection bin 3.

[0047] In the specimen pneumatic transmission and receiving device of this embodiment, a front door 14 is detachably installed on the outer shell 1, a touch screen 15 is arranged on the front door 14, and the touch screen 15 is respectively in signal connection with the counting component 5, the push rod motor 11 and the position sensor 13.
