Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer tube technology, specifically to a body fluid specimen transfer tube. Background Technology
[0002] Pneumatic pipeline logistics transport systems are automated systems that utilize air pressure differences to rapidly transport goods through pipelines. In hospitals, this system connects key departments such as pharmacies, laboratories, operating rooms, and blood banks, accurately transporting medicines, blood samples, pathological specimens, and small medical instruments at a speed of 6-8 meters per second, thereby significantly improving the efficiency of medical resource turnover. In addition, the entire transport process is closed and traceable, effectively avoiding cross-contamination and human error that can occur with manual transport.
[0003] Currently, hospitals use pneumatic transport containers to transfer blood and body fluid (urine, feces, sputum, etc.) samples. During sample transfer, blood collection tubes are inserted into fixed holes in the sponge inside the transport container. However, because the size of body fluid containers does not match the sponge's holes, they must be placed in sealed bags inside the container and covered with sponge for cushioning. In actual transport, vibrations within the transport container can cause internal shaking, easily leading to loose sputum container lids and leakage, resulting in sample waste and requiring patients to re-sample, directly extending the time for test report processing.
[0004] Therefore, how to design a specimen transport container that can avoid sputum leakage and contamination and prevent delays in test reports is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0014] As a preferred embodiment, the main body tube also has at least one toilet tube placement cavity, the toilet tube placement cavity having a fourth top opening;
[0015] It also includes at least one toilet tube buffer sleeve, which is fixedly installed in the toilet tube placement cavity through the fourth top opening, and the toilet tube can be inserted into the toilet tube buffer sleeve; after the sleeve cover is connected to the main sleeve cover, the inner top wall of the sleeve cover abuts against the cap of the toilet tube.
[0016] As a preferred embodiment, the outer wall of the arc-shaped connecting piece is provided with external threads, the inner wall of the limiting cover is provided with internal threads, and the limiting cover is screwed to the arc-shaped connecting piece, thereby being detachably installed together with the arc-shaped connecting piece.

[0021] As a preferred embodiment, an elongated limiting block is provided on one inner side wall of the slot; the locking block is L-shaped, and after the locking block is inserted into the slot, the cylindrical cover is rotated circumferentially to turn the free end of the locking block to the underside of the elongated limiting block, and the free end of the locking block is limited by the elongated limiting block, thereby connecting the cylindrical cover with the main cylindrical cover.
[0022] As a preferred embodiment, a cushioning sponge sheet is also included, disposed on the inner top wall of the cylinder cover.

The tube cap can be connected to the main tube cap, and its inner top wall abuts against the limiting cap and the cap of the blood collection tube.
[0028] When transferring bodily fluid samples, a sputum container containing a sputum sample is placed inside the sputum container placement cavity. A limiting cap is then installed on the arc-shaped connecting piece to secure the sputum container. A blood collection tube containing a blood sample is placed inside a blood vessel buffer sleeve (made of polyethylene, which is lightweight, provides good cushioning, and is low in cost). The sleeve cap is then connected and fixed to the main body sleeve cap. The fixed transfer tube is placed into a sealed pipeline. A blower is activated to create an air pressure difference within the pipeline. The thrust or pull force generated by compressed air drives the transfer tube to move at high speed along a predetermined path within the pipeline. During the transfer, a steering device controls the direction of travel to ensure the correct route. When the transfer tube reaches the target station, the system adjusts the air pressure to decelerate the transfer tube and bring it to a precise stop. Finally, the pipeline port at the corresponding station is opened to complete the reception of the transfer tube. This utility model of a bodily fluid sample transfer tube places the sputum container inside the sputum container placement cavity and uses a limiting cap to secure the sputum container cap, preventing accidental opening and sputum leakage and contamination, thereby ensuring timely issuance of test reports.

[0038] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example
[0039] This embodiment provides a body fluid specimen transfer tube, such as Figure 1-3As shown, it includes: a main body cylinder 1, an arc-shaped connecting piece 2, a limiting cover 3, a vascular buffer sleeve 4, and a cylinder cover 5; wherein, the main body cylinder 1 has at least one sputum container placement cavity 11, the sputum container placement cavity 11 having a first top opening, through which a sputum container 12 can be placed; the main body cylinder 1 also has several vascular placement cavities 13, the vascular placement cavities 13 having a second top opening; there are two arc-shaped connecting pieces 2, disposed on the end face of the main body cylinder 1, located on both sides of the first top opening; limiting... The limiting cover 3 is detachably installed on the arc-shaped connecting piece 2. After the limiting cover 3 is installed on the arc-shaped connecting piece 2, the inner top wall of the limiting cover 3 abuts against the lid of the sputum container 12. Several blood vessel buffer sleeves 4 are fixedly installed in the blood vessel placement cavity 13 through the second top opening. The blood collection tube 41 can be inserted into the blood vessel buffer sleeve 4. The tube cover 5 can be connected to the main body tube 1. After the tube cover 5 is connected to the main body tube 1, the inner top wall of the tube cover 5 abuts against the limiting cover 3 and the cap of the blood collection tube 41.
[0040] When transferring bodily fluid samples, the sputum container 12 containing the sputum sample is placed in the sputum container placement cavity 11, and then the limiting cap 3 is installed on the arc-shaped connecting piece 2 to limit and fix the sputum container 12. The blood collection tube 41 containing the blood sample is placed in the blood vessel buffer sleeve 4 (the sleeve is made of polyethylene material, which has the characteristics of being lightweight, having good buffering effect, and being low in cost), and then the sleeve cap 5 is connected and fixed to the main body tube 1. The fixed transfer tube is placed into the sealed pipeline, and the blower is started to create an air pressure difference in the pipeline. The thrust or pull force generated by the compressed air drives the transfer tube to move at high speed along the predetermined path in the pipeline. During the transfer, the direction of travel is controlled by the steering device to ensure the correct route. When the transfer tube reaches the target station, the system adjusts the air pressure to decelerate the transfer tube and stop it precisely. Finally, the pipeline port of the corresponding station is opened to complete the reception of the transfer tube. In this embodiment, the body fluid specimen transfer tube places the sputum container 12 inside the sputum container placement cavity 11 and uses a limiting cover 3 to limit and fix the lid of the sputum container 12 to prevent accidental opening and sputum leakage and contamination, thereby ensuring that the test report is issued on time.

[0046] It also includes a cushioning sponge sheet 6, which is disposed on the inner top wall of the tube cover 5. After the tube cover 5 is closed to the main tube 1, the cushioning sponge sheet 6 abuts against the limiting cover 3, the cap of the blood collection tube 41, the cap of the urine tube 15, and the cap of the stool tube 17, which can further cushion the vibration.
[0047] It also includes several annular buffer strips 61, which are evenly distributed on the outer wall of the main body cylinder 1. The annular buffer strips 61 can absorb external impacts, reduce vibrations transmitted into the main body cylinder 1, and enhance the overall buffering effect.
[0048] The top of the cylinder cover 5 is provided with a carrying strap 62. The carrying strap 62 makes it convenient for users to lift the cylinder and improves ease of use.
[0049] A groove 63 is provided in the middle of the top surface of the cylinder cover 5, and the carrying strap 62 is provided in the groove 63 to facilitate the finger picking up the carrying strap 62.

The free end of the locking block 52 is limited by the long strip limiting block 53, thereby connecting the tube cover 5 and the main tube 1 together.
[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
