Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pneumatic logistics transportation, and in particular to a sample tube carrier for a pneumatic logistics transportation system. BACKGROUND

[0002] Existing pneumatic logistics transportation systems have been widely used in hospitals, laboratories and other scenarios for the cross-building, cross-floor fast delivery of biological samples such as blood, urine and tissue. However, most existing carriers use rigid plastic cylinders or foam pad structures, and sample tubes are simply inserted and fixed by interference fit or additional fillers (such as sponge, rubber ring). This structure is prone to shaking, collision under high-speed airflow impact, sudden stop or turning, resulting in tube rupture, cap loosening or label wear, and in severe cases, sample leakage and cross-contamination.

[0003] Traditional sample tube carriers mainly use rigid cylinders (such as CN201626617U) or simple foam pad structures. Although this structure can provide basic accommodation space, there is still a large gap between the sample tube and the cylinder wall under high-speed airflow impact, sudden stop or turning conditions, which can cause tube shaking, collision, and is prone to rupture, cap loosening or label wear. In order to improve the buffering performance, CN201626617U further proposes to set several inflatable airbags on the inner surface of the rigid box, and inflate the airbags by an external inflation pump to cover the items, but it cannot be directly transplanted to the existing pneumatic logistics transportation scenarios that require efficient loading and unloading and quick inflation protection.

[0004] CN110758639A discloses a foldable airbag structure, but its original intention is to be used for buoyancy components of water-based equipment, and the airbag body adopts a step-by-step inflation / deflation method to realize folding and storage. This structure is difficult to be applied to the radial clamping of slender objects (such as sample tubes), and relies on manual operation for automatic inflation and deflation control, so it cannot be directly transplanted to the existing pneumatic logistics transportation scenarios that require efficient loading and unloading and quick inflation protection.

[0005] Therefore, based on the research and design of a sample tube carrier for a pneumatic logistics transportation system that can be efficiently loaded and unloaded and quickly inflated for protection. SUMMARY

[0020] Further, the air charging and discharging assembly comprises a gas pump, an electromagnetic valve connected with an output end of the gas pump, and the electromagnetic valve and the gas pump are in communication connection with the single-chip microcomputer respectively.

[0021] Further, the buckling assembly is a magnetic attraction buckle or a pressing buckle.

[0022] Further, the buckling assembly comprises a male buckle and a female buckle, and the first pressure sensor is arranged in a groove of the female buckle.

[0032] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. In the technical solution, components, material names, connection structures, circuit structures, control methods, algorithms, and other features that are not explicitly described are considered as common technical features disclosed in the prior art.

[0033] Embodiment 1

[0034] The present embodiment provides a sample tube carrier for a pneumatic logistics transportation system, as shown in Figures 1 to 4 , comprising a transparent outer shell 1 and a rolled carrier 2 arranged in the transparent outer shell 1, the rolled carrier 2 comprising an inflatable body 21 and a plurality of loading bags 22 arranged on the inflatable body 21; the sample tube carrier further comprises a gas charging and discharging assembly connected with the rolled carrier 2, a buckle assembly arranged on both sides of the rolled carrier 2, a first pressure sensor arranged on the buckle assembly, and a single-chip microcomputer 4 in communication connection with the first pressure sensor. The single-chip microcomputer 4 is in communication connection with the gas charging and discharging assembly.

[0035] The buckle assembly is a magnetic buckle or a press buckle. The buckle assembly comprises a male buckle 9 and a female buckle 10, and the first pressure sensor is arranged inside the groove of the female buckle.

[0036] The rolled carrier 2 can be connected end to end through the buckle assembly, and the single-chip microcomputer 4 can determine the state of the rolled carrier 2 based on the electrical signal output by the first pressure sensor: when the rolled carrier 2 is connected end to end, the single-chip microcomputer 4 instructs the gas charging and discharging assembly to inflate the rolled carrier 2, so that the sample tubes 3 in the loading bags 22 are fixed under pressure; when the rolled carrier 2 is separated end to end, the single-chip microcomputer 4 instructs the gas charging and discharging assembly to deflate the rolled carrier 2, so that the sample tubes 3 in the loading bags 22 are released from the pressure.

[0037] The gas charging and discharging assembly comprises a gas pump 6, an electromagnetic valve 7 connected with the output end of the gas pump 6, and the electromagnetic valve 7 and the gas pump 6 are in communication connection with the single-chip microcomputer 4, respectively.

[0038] Each loading bag 22 is used to accommodate a sample tube 3. The air cavity inside the inflatable body 21 is communicated with the inflation and deflation assembly through the air guide pipe. The air pump 6, the electromagnetic valve 7 and the single-chip microcomputer 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 into the corresponding loading bags 22 one by one, and then overlaps the winding carrier 2 at the head and tail, so that the male buckle 9 is aligned with the female buckle 10 and buckled. At this time, the first pressure sensor in the female buckle 10 groove senses the buckling pressure and immediately outputs an electrical signal to the single-chip microcomputer 4. The single-chip microcomputer 4 determines that the winding carrier 2 has been in the winding state, and then instructs the air pump 6 to start and the electromagnetic valve 7 to open, so that the air pump 6 inflates the inflatable body 21. When the single-chip microcomputer 4 calculates the predetermined inflation time, the single-chip microcomputer 4 instructs the air pump 6 to stop and the electromagnetic valve 7 to close. The inflated inflatable body 21 radially extrudes the loading bag 22, so that the sample tube 3 in the bag is uniformly pressed and fixed, which not only prevents shaking during transportation, but also avoids collision damage. On the contrary, when arriving at the destination and needing to be unloaded, the operator disconnects the male buckle 9 from the female buckle 10, the first pressure sensor loses the pressure signal, and the single-chip microcomputer 4 controls the electromagnetic valve 7 to reverse, so that the gas in the inflatable body 21 is discharged in the reverse direction through the air pump 6. The inflatable body 21 is retracted, the loading bag 22 is relaxed, and the sample tube 3 is released from the pressure and can be easily taken out. The magnetic or pressing type buckling structure ensures reliable closure and convenient opening. The closed-loop system composed of the single-chip microcomputer 4, the air pump 6, the electromagnetic valve 7 and the first pressure sensor realizes the automation of the inflation-deflation-locking-releasing action.

[0039] The transparent outer shell 1 can adopt a middle buckling type opening or a two-end cover type opening. Since the structure of the transparent outer shell 1 is a prior art, any existing pneumatic pipeline type transportation mode can be used, and details are not repeated here.

[0040] The power supply of the electric equipment and components in each embodiment of the application can be provided by a storage battery. The selection of the storage battery and the design of the power supply circuit are prior arts, and details are not repeated here.

[0041] Embodiment 2

[0042] In this embodiment, each loading bag 22 is provided with a second pressure sensor 5 at the position corresponding to the inflatable body 21. Each second pressure sensor 5 is in communication connection with the single-chip microcomputer 4.

[0043] The sample tube carrier further comprises an indicator lamp 8 arranged on the inflatable body 21. The indicator lamp 8 is in communication connection with the single-chip microcomputer 4. The indicator lamp 8 is used to indicate whether the winding carrier 2 is still loaded with the sample tube 3.

[0044] In specific implementation, the single-chip microcomputer 4 judges whether there is sample tube 3 in the loading bag 22 based on the electrical signal fed back by each second pressure sensor 5. When the single-chip microcomputer 4 judges that there is sample tube 3 in the loading bag 22, the single-chip microcomputer 4 instructs the indicator lamp 8 to emit light. When the single-chip microcomputer 4 judges that all sample tubes 3 have been taken out of the loading bag 22 based on the pressure electrical signal fed back by the second pressure sensor 5, the single-chip microcomputer 4 instructs the indicator lamp 8 to be turned off.

[0045] In specific implementation, the second pressure sensor 5 is additionally arranged at a corresponding position of each loading bag 22 of the inflatable main body 21, and the indicator lamp 8 in communication with the single-chip microcomputer 4 is arranged on the outer surface of the main body 21. When the sample tube 3 is inserted into the loading bag 22, the sidewall of the sample tube 3 continuously presses the second pressure sensor 5, the single-chip microcomputer 4 judges that the bag still carries the sample tube 3 based on the electrical signal of the second pressure sensor 5, and then the indicator lamp 8 is turned on to light to indicate to the operator that there is still tube body not taken out. When all sample tubes 3 are taken out in sequence, the single-chip microcomputer 4 collects all channel signals and confirms that there is no load, and then the indicator lamp 8 is turned off to realize real-time visual feedback of the loading state, thereby avoiding the omission of sample tubes 3.
