Description

Technical Field

[0001] This utility model relates to the field of pneumatic fluid transport technology, and in particular to a sample tube carrier for a pneumatic fluid transport system. Background Technology

[0002] Existing pneumatic transport systems are widely used in hospitals, laboratories, and other settings for the rapid delivery of biological samples such as blood, urine, and tissues across buildings and floors. However, most existing carriers use rigid plastic cylinders or foam-lined structures, with sample tubes simply inserted and secured by interference fits or additional fillers (such as sponges or rubber rings). This structure is prone to shaking and collisions when subjected to high-speed airflow impacts, sudden stops, or turns, leading to tube breakage, loosening of caps, or label wear, and in severe cases, sample leakage and cross-contamination.

[0003] Traditional sample tube carriers primarily employ rigid cylindrical bodies (such as CN201626617U) or simple foam-lined structures. While these structures provide basic containment space, significant gaps remain between the sample tube and the cylinder wall under high-speed airflow impact, sudden stops, or turns, leading to tube swaying, collisions, and a high risk of breakage, cap detachment, or label wear. To improve cushioning performance, CN201626617U further proposes inflatable air bladders on the inner surface of the rigid housing, which are inflated by an external pump to cover the sample. However, this approach cannot be directly applied to existing pneumatic logistics transport scenarios requiring efficient loading and unloading and rapid inflation protection.

[0004] While CN110758639A discloses a foldable airbag structure, its original design was intended for buoyancy components in aquatic equipment. The airbag body uses a step-by-step inflation / deflation method with mother and daughter air chambers to achieve folding and storage. This structure is difficult to apply to radial clamping of slender items (such as sample tubes), and automatic inflation / deflation control relies on manual operation. Therefore, it cannot be directly transplanted to existing pneumatic logistics transport scenarios that require efficient loading and unloading and rapid inflation protection.

[0005] Therefore, we need to develop and design a sample tube carrier for pneumatic fluid transport systems that can be efficiently loaded and unloaded and quickly inflated for protection. Utility Model Content

[0006] The purpose of this invention is to overcome the defects of the prior art and provide a sample tube carrier for a pneumatic fluid transport system. Through the integrated design of snap-fit-sensing-closed-loop inflation, the sample tube is automatically and securely clamped and quickly released in the pneumatic fluid carrier, taking into account both high-speed and safe transport and convenient loading and unloading.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] This utility model provides a sample tube carrier for a pneumatic fluid transport system, including a transparent outer shell and a winding carrier disposed in the transparent outer shell. The winding carrier includes an inflatable main body and a plurality of loading bags disposed on the inflatable main body.

[0009] The sample tube carrier also includes an inflation / deflation assembly connected to the winding carrier, a fastening assembly located on both sides of the winding carrier, a first pressure sensor located on the fastening assembly, and a microcontroller communicatively connected to the first pressure sensor.

[0010] The microcontroller is communicatively connected to the inflation / deflation assembly.

[0011] The winding carrier can be connected end to end by a fastening assembly, and the microcontroller can determine the state of the winding carrier based on the electrical signal output by the first pressure sensor.

[0012] When the winding carrier is connected end to end, the microcontroller instructs the inflation / deflation assembly to inflate the winding carrier, so that the sample tube in the loading bag is pressed and fixed.

[0013] When the winding carrier separates from its end, the microcontroller instructs the inflation / deflation assembly to deflate the winding carrier, thereby relieving the pressure on the sample tube in the loading bag.

[0014] Furthermore, the inflatable body includes a plate-shaped flexible main air bladder cavity and a plurality of strip-shaped air bladder cavities disposed on one side of the plate-shaped flexible main air bladder cavity, and each of the strip-shaped air bladder cavities is connected to the plate-shaped flexible main air bladder cavity.

[0015] Furthermore, the loading bag is located on the side of the plate-shaped flexible main airbag cavity that does not have a strip-shaped airbag cavity.

[0016] Furthermore, the loading bag includes a flexible material with three sides attached to the plate-shaped flexible main air bladder cavity, and the loading bag and one side outer wall of the plate-shaped flexible main air bladder cavity form a bag structure capable of loading sample tubes.

[0017] Furthermore, the loading bag includes a thin air bladder cavity with three sides connected to the plate-shaped flexible main air bladder cavity, and the loading bag and one side outer wall of the plate-shaped flexible main air bladder cavity form a bag structure capable of loading sample tubes.

[0018] Furthermore, each inflatable main body position corresponding to each loading bag is provided with a second pressure sensor, and each second pressure sensor is communicatively connected to the microcontroller.

[0019] Furthermore, the sample tube carrier also includes an indicator light on the inflatable main body. The indicator light is connected to a microcontroller and is used to indicate whether there are still sample tubes loaded on the winding carrier.

[0020] Furthermore, the inflation / deflation assembly includes an air pump, a solenoid valve connected to the output end of the air pump, and the solenoid valve and the air pump are respectively communicatively connected to the microcontroller.

[0021] Furthermore, the fastening component is a magnetic snap or a push-button snap.

[0022] Furthermore, the fastening assembly includes a male buckle and a female buckle, and the first pressure sensor is disposed inside the groove of the female buckle.

[0023] The technical principle of this utility model is as follows:

[0024] This invention utilizes a three-in-one technical principle of flexible airbag, electronic sensing, and closed-loop control. Multiple sample tubes are inserted into independent loading bags on a winding carrier, and then magnetically locked at both ends by fastening components on both sides. This action triggers the first pressure sensor in the female buckle groove, which immediately outputs an electrical signal to the microcontroller. After determining the locking state, the microcontroller instructs the air pump-solenoid valve assembly to inflate the inflatable main body, applying radial pressure to the sample tubes in each loading bag. This ensures stable and collision-free fixation even under high-speed airflow, sudden stops, or turns. Upon reaching the destination, the operator simply opens the transparent outer shell, releases the fastening of the winding carrier, and the microcontroller immediately instructs the solenoid valve to deflate, causing the inflatable main body to retract and the loading bags to release pressure.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] This utility model's sample tube carrier is compatible with existing pneumatic logistics systems and is easy to use. When the winding carrier is locked at both ends by the male and female buckles, the first pressure sensor immediately senses and transmits a signal to the microcontroller. The microcontroller then instructs the inflation / deflation assembly to automatically inflate the inflatable main body. The inflated main body generates radial pressure on all sample tubes in the loading bag, achieving stable clamping without shaking or collision, effectively preventing tube breakage or label detachment caused by high-speed airflow impact. Upon reaching the transport destination, simply release the buckles; the first pressure sensor signal is interrupted, and the microcontroller immediately controls deflation. The main body retracts, the loading bag contacts the locking force, and the sample tubes can be quickly removed. The entire clamping and release process is controlled in a closed loop by the microcontroller, eliminating the need for manual air pressure adjustment, reducing operational intensity, and providing reliable protection for high-speed sample transport in scenarios such as hospitals.

Detailed Implementation

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Component models, material names, connection structures, circuit structures, control methods, algorithms, and other features not explicitly described in this technical solution are considered common technical features disclosed in the prior art.

[0033] Example 1

[0034] This embodiment provides a sample tube carrier for a pneumatic fluid transport system. See [link to documentation]. Figures 1 to 4 The device includes a transparent outer shell 1 and a winding carrier 2 disposed within the transparent outer shell 1. The winding carrier 2 includes an inflatable main body 21 and multiple loading bags 22 disposed on the inflatable main body 21. The sample tube carrier also includes an inflation / deflation assembly connected to the winding carrier 2, fastening assemblies disposed on both sides of the winding carrier 2, a first pressure sensor disposed on the fastening assembly, and a microcontroller 4 communicatively connected to the first pressure sensor. The microcontroller 4 is communicatively connected to the inflation / deflation assembly.

[0035] The fastening assembly is a magnetic snap or a push-button snap. The fastening assembly includes a male snap 9 and a female snap 10, and the first pressure sensor is located inside the groove of the female snap.

[0036] The winding carrier 2 can be connected end to end by the fastening assembly. The microcontroller 4 can determine the state of the winding carrier 2 based on the electrical signal output by the first pressure sensor: when the winding carrier 2 is connected end to end, the microcontroller 4 instructs the inflation / deflation assembly to inflate the winding carrier 2, so that the sample tube 3 in the loading bag 22 is pressed and fixed; when the winding carrier 2 is separated end to end, the microcontroller 4 instructs the inflation / deflation assembly to deflate the winding carrier 2, so that the sample tube 3 in the loading bag 22 is released from pressure.

[0037] The inflation / deflation assembly includes an air pump 6, a solenoid valve 7 connected to the output end of the air pump 6, and the solenoid valve 7 and the air pump 6 are respectively connected to the microcontroller 4 for communication.

[0038] Each loading bag 22 is used to hold one sample tube 3. The air chamber inside the inflatable main body 21 is connected to the inflation / deflation assembly via an air guide tube. The air pump 6, solenoid valve 7, and microcontroller 4 form a closed-loop control through signal lines. When the system is in the loading stage, the operator flattens the winding carrier 2, inserts the sample tubes 3 one by one into the corresponding loading bag 22, and then aligns the ends of the winding carrier 2 so that the male buckle 9 is aligned with the female buckle 10 and fastened. At this time, the first pressure sensor in the groove of the female buckle 10 senses the fastening pressure and immediately outputs an electrical signal to the microcontroller 4. Based on this, the microcontroller 4 determines that the winding carrier 2 is in the winding state, and then instructs the air pump 6 to start and the solenoid valve 7 to open, inflating the inflatable body 21 with gas. When the timer in the microcontroller 4 calculates that the predetermined inflation time has been reached, the microcontroller 4 instructs the air pump 6 to stop and the solenoid valve 7 to close. The inflated inflatable body 21 radially compresses the loading bag 22, so that the sample tube 3 inside the bag is evenly compressed and fixed, which not only prevents shaking during transportation, but also avoids collision damage. Conversely, when unloading is required upon arrival at the destination, the operator disconnects the male buckle 9 from the female buckle 10. The first pressure sensor loses the pressure signal, and the microcontroller 4 controls the solenoid valve 7 to switch, so that the gas in the inflatable body 21 is discharged in the reverse direction through the air pump 6. The inflatable body 21 retracts, the loading bag 22 loosens, the sample tube 3 is relieved of pressure, and can be easily taken out. The magnetic or press-type fastening structure ensures reliable closure and convenient opening; the closed-loop system composed of the microcontroller 4, air pump 6, solenoid valve 7 and the first pressure sensor realizes the automation of the inflation-deflation-locking-release action.

[0039] The transparent outer shell 1 can adopt a central snap-fit ​​opening or a two-end cap-fit ​​opening. Since the structure of the transparent outer shell 1 is existing technology, it can be used as long as it is suitable for the existing pneumatic pipeline transportation mode, which will not be elaborated here.

[0040] In all embodiments of this utility model, the electrical equipment and components can be powered by storage batteries. The selection of storage batteries and the design of power supply circuits are existing technologies and will not be described in detail here.

[0041] Example 2

[0042] In this embodiment, each inflatable body 21 corresponding to each loading bag 22 is provided with a second pressure sensor 5, and each second pressure sensor 5 is communicatively connected to the microcontroller 4.

[0043] The sample tube carrier also includes an indicator light 8 on the inflatable main body 21. The indicator light 8 is connected to the microcontroller 4 and is used to indicate whether there is still a sample tube 3 loaded on the winding carrier 2.

[0044] In practice, the microcontroller 4 determines whether there are still sample tubes 3 in the loading bag 22 based on the electrical signals fed back by each of the second pressure sensors 5. When the microcontroller 4 determines that there are still sample tubes 3 in the loading bag 22, the microcontroller 4 command indicator 8 lights up. When the microcontroller 4 determines that all sample tubes 3 have been removed from the loading bag 22 based on the pressure electrical signals fed back by the second pressure sensors 5, the microcontroller 4 command indicator 8 turns off.

[0045] In specific implementation, a second pressure sensor 5 is added to each loading bag 22 of the inflatable main body 21 at a corresponding position, and an indicator light 8 communicating with the microcontroller 4 is arranged on the outer surface of the main body 21. When the sample tube 3 is inserted into the loading bag 22, its side wall generates continuous pressure on the second pressure sensor 5. The microcontroller 4 determines that the bag still contains the sample tube 3 based on the electrical signal of the second pressure sensor 5, and then lights up the indicator light 8 to indicate to the operator that there are still tubes that have not been removed. When all the sample tubes 3 are pulled out in sequence, the microcontroller 4 summarizes all channel signals and confirms that there is no load, and then turns off the indicator light 8 to realize real-time visual feedback of the loading status, thereby avoiding the omission of sample tubes 3.

[0046] In specific implementation, the microcontroller, the first pressure sensor, the second pressure sensor 5, and the solenoid valve 7 in each embodiment of this utility model can all be selected from commonly used models known to those skilled in the art, and the air pump 6 can be selected from a corresponding model of small or micro air pump. The specific selection process will not be described in detail.
