Description

Technical Field

[0001] This utility model relates to the field of transmission tube technology, specifically to a blood specimen transmission 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 tubes as the transport medium for blood samples, with sponges inside to secure and cushion them. However, the following problems exist in actual transport: the size of the sponges is not well-suited; if they are too long, the inserted blood sample is difficult to remove; if they are too short, they cannot effectively cushion the sample, causing the container lid to loosen and spill during transport. Furthermore, the continuous vibration of the blood samples can cause hemolysis, requiring the laboratory to frequently determine whether the hemolysis is caused by improper blood collection or transport, objectively increasing the risk of medical disputes. Additionally, the lids of the pneumatic tubes are snap-on, making them prone to accidental opening due to changes in air pressure or mechanical vibration during transport.

[0004] Therefore, how to design a specimen transfer tube that can prevent specimen spillage and hemolysis when transferring blood specimens is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects in the prior art where the size of the buffer sponge is not suitable. If it is too long, the specimen will be difficult to pull out, and if it is too short, the buffer will be insufficient, resulting in blood specimen spillage and hemolysis during transportation. Thus, a blood specimen transport tube that can avoid blood specimen spillage and hemolysis during specimen transport is provided.

[0006] Therefore, this utility model provides a blood sample transfer tube, comprising:

[0007] The main body has several receiving cavities, each receiving cavity having a top opening;

[0008] The first buffer sleeve, consisting of several, is fixedly installed in the receiving cavity through the top opening, and the blood collection tube can be inserted into the first buffer sleeve.

[0009] The tube cap can be connected to the main tube cap via a snap-fit ​​structure. After the tube cap is connected to the main tube cap, the inner top wall of the tube cap abuts against the cap of the blood collection tube.

[0010] As a preferred embodiment, the snap-fit ​​structure includes:

[0011] There are four slots, which are evenly distributed around the end face of the main body cylinder;

[0012] Four locking blocks are evenly arranged circumferentially on the cylinder cover; the locking blocks can match and engage with the locking slots, thereby locking the cylinder cover onto the main cylinder.

[0013] As a preferred embodiment, the card slot includes an insertion portion and a limiting portion communicating with the insertion portion, wherein a limiting strip is formed on the inner wall of the limiting portion;

[0014] The locking block includes a connecting part and a locking part formed at the free end of the connecting part. The axis of the locking part forms a 90° angle with the axis of the connecting part. When the cylinder cover is locked to the main body cylinder, after the locking part is inserted into the insertion part, the cylinder cover is rotated circumferentially to turn the locking part into the limiting part and is limited by the limiting strip, thereby locking the cylinder cover and the main body cylinder together.

[0015] As a preferred embodiment, a circular cushioning sponge sheet is provided on the inner top wall of the cylinder cover; after the cylinder cover is connected to the main cylinder cover, the cap of the blood collection tube abuts against the cushioning sponge sheet.

[0016] As a preferred embodiment, a second buffer sleeve is also included, which is fitted onto the outer wall of the main cylinder.

[0017] As a preferred embodiment, the device also includes a lid carrying strap, which is mounted on top of the lid via a mounting structure.

[0018] As a preferred embodiment, the mounting structure includes:

[0019] The mounting slots are two in number and are spaced apart on the top of the cylinder cover;

[0020] Four elastic clips are formed on both sides of the two ends of the cap carrying strap. When the cap carrying strap is installed on the cap, an external force is applied to push the two ends of the cap carrying strap, causing the elastic clips to deform under the pressure of the inner wall of the mounting strip hole and enter the mounting strip hole, thereby installing the cap carrying strap on the cap.

[0021] As a preferred embodiment, a groove is formed in the middle of the top surface of the cylinder cover, and the cylinder cover lifting strap is installed in the groove.

[0022] The technical solution provided by this utility model has the following advantages:

[0023] The blood sample transfer tube of this utility model includes a main tube, a first buffer sleeve, and a tube cap; wherein, the main tube has several receiving cavities, and each receiving cavity has a top opening; several first buffer sleeves are fixedly installed in the receiving cavities through the top openings, and blood collection tubes can be inserted into the first buffer sleeves; the tube cap can be connected to the main tube cap through a snap-fit ​​structure, and after the tube cap is connected to the main tube cap, the inner top wall of the tube cap abuts against the cap of the blood collection tube.

[0024] During blood sample transfer, the blood collection tube containing the blood sample is placed inside the first buffer sleeve (made of polyethylene, which is lightweight, provides good cushioning, and is low in cost). The sleeve cap is then attached to the main sleeve cap to secure the blood collection tube. The secured transfer tube is placed into a sealed pipeline. A blower is activated to create a 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 transfer, a steering device controls the direction of travel to ensure correct route accuracy. When the transfer tube reaches the target station, the system adjusts the air pressure to decelerate the 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 invention provides a blood sample transfer tube that effectively prevents sample spillage and hemolysis during transport. Specifically, the blood collection tube is placed inside a first buffer sleeve, which reduces the impact of transport vibrations on the blood collection tube and enhances the stability of the tube, thereby preventing hemolysis. In addition, the snap-fit ​​structure reliably fixes the cap to the main tube, and the pre-tightening pressure applied to the cap by the inner wall of the cap prevents the cap from loosening and avoids spillage.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0034] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0035] This embodiment provides a blood sample transfer tube, such as Figure 1-2 As shown, it includes: a main body cylinder 1, a first buffer sleeve 2, and a cap 4; wherein, the main body cylinder 1 has a plurality of receiving cavities 11, each receiving cavity 11 having a top opening; there are a plurality of first buffer sleeves 2, which are fixedly installed in the receiving cavities 11 through the top openings, and blood collection tubes 3 can be inserted into the first buffer sleeves 2; the cap 4 can be connected to the main body cylinder 1 through a snap-fit ​​structure, and after the cap 4 is connected to the main body cylinder 1, the inner top wall of the cap 4 abuts against the cap of the blood collection tube 3.

[0036] When transferring blood samples, the blood collection tube 3 containing the blood sample is placed inside the first buffer sleeve 2 (the sleeve is made of polyethylene, which is lightweight, has good cushioning effect, and is low in cost). Then, the sleeve cap 4 is attached to the main body tube 1 to fix the blood collection tube 3. 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 a 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 blood sample transfer tube can effectively avoid sample spillage and hemolysis during the transfer process. Specifically, the blood collection tube 3 is placed inside the first buffer sleeve 2. The buffering effect of the sleeve reduces the impact of transport vibration on the blood collection tube 3, enhances the stability of the tube body, and thus prevents hemolysis. In addition, the cap 4 is reliably fixed to the main tube 1 through the snap-fit ​​structure, and the pre-tightening pressure applied to the cap of the blood collection tube 3 by the inner wall of the cap 4 can prevent the cap from loosening and avoid spillage.

[0037] like Figure 2-3 As shown, the snap-fit ​​structure includes a snap-fit ​​groove 5 and a snap-fit ​​block 51; wherein, there are four snap-fit ​​grooves 5, which are evenly distributed circumferentially on the end face of the main body cylinder 1; there are four snap-fit ​​blocks 51, which are evenly distributed circumferentially on the cylinder cover 4; the snap-fit ​​blocks 51 can match and snap-fit ​​with the snap-fit ​​grooves 5, thereby snapping the cylinder cover 4 onto the main body cylinder 1.

[0038] like Figure 3As shown, the slot 5 includes an insertion part 52 and a limiting part 53 communicating with the insertion part 52. A limiting strip 54 is formed on the inner wall of the limiting part 53. The locking block 51 includes a connecting part 55 and a locking part 56 formed at the free end of the connecting part 55. The axis of the locking part 56 forms a 90° angle with the axis of the connecting part 55. When the cylinder cover 4 is locked with the main body cylinder 1, after the locking part 56 is inserted into the insertion part 52, the cylinder cover 4 is rotated circumferentially to rotate the locking part 56 into the limiting part 53 and is limited by the limiting strip 54, thereby locking the cylinder cover 4 and the main body cylinder 1 together.

[0039] A circular buffer sponge sheet 41 is provided on the inner top wall of the cylinder cover 4; after the cylinder cover 4 is connected to the main cylinder 1, the cap of the blood collection tube 3 abuts against the buffer sponge sheet 41. The buffer sponge sheet 41 can further buffer the vibration of the blood collection tube 3, thereby reducing the vibration of the blood collection tube 3 and preventing hemolysis.

[0040] It also includes a second buffer sleeve 6, which is fitted onto the outer wall of the main body cylinder 1. The second buffer sleeve 6 can absorb external impacts, reduce the transmission of vibration to the blood collection tube 3, and enhance the overall buffering effect.

[0041] like Figure 2 , 4 As shown, it also includes a lid carrying strap 7, which is installed on the top of the lid 4 via an installation structure. The lid carrying strap 7 facilitates user extraction and improves ease of use.

[0042] like Figure 4 As shown, the mounting structure includes mounting slots 71 and elastic retaining strips 72; wherein, there are two mounting slots 71, which are opened at a certain distance on the top of the cylinder cover 4; there are four elastic retaining strips 72, which are respectively formed on both sides of the cylinder cover lifting strap 7; when the cylinder cover lifting strap 7 is installed on the cylinder cover 4, by applying an external force to push the two ends of the cylinder cover lifting strap 7, the elastic retaining strips 72 are deformed by the compression of the inner wall of the mounting slots 71 and enter into the mounting slots 71, thereby installing the cylinder cover lifting strap 7 on the cylinder cover 4.

[0043] A groove 42 is formed in the middle of the top surface of the cylinder cap 4, and the cylinder cap carrying strap 7 is installed in the groove 42. The groove 42 is designed to facilitate the use of fingers to pick up the cylinder cap carrying strap 7.

[0044] 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.
