Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a remote sample delivery receiving device and its receiving method. Background Technology

[0002] In the field of in vitro diagnostics (IVD), the transfer of samples between different departments, floors, and even buildings is still mainly done manually. Manual transfer is not only time-consuming and labor-intensive, but also carries the potential risk of incorrect sample delivery due to sorting errors. To address this issue, automated remote sample delivery systems have been gradually implemented. In these systems, the core technical challenge lies in how to effectively decelerate, accurately identify, and reliably analyze samples arriving at high speeds at the receiving end. If improper deceleration occurs upon arrival at the receiving end, resulting in impact, it may cause air bubbles to form in the plasma or serum to mix with blood cells again, directly affecting the accuracy of subsequent test results. Furthermore, deviations in sample information verification could lead to serious medical accidents where test results do not match patient information.

[0003] In existing technologies, deceleration schemes for remote sample delivery receivers mainly fall into two categories: one is pneumatic reverse propulsion, which decelerates the sample through reverse airflow; the other is soft impact, which absorbs the sample's kinetic energy through elastic materials or structures. However, the pneumatic reverse propulsion scheme has inherent drawbacks: its reverse airflow must counteract the forward compressed air at the transmitting end, resulting in only one receiver within the same transmission pipe, a long single-sample transmission cycle, and low overall system throughput efficiency. Furthermore, this scheme requires an additional air source, increasing equipment purchase and operating costs, and generates significant noise during operation. While the soft impact scheme does not require an air source, its buffer material is prone to wear during repeated contact with the sample tube, and the impact itself still causes mechanical shock to the sample. Especially for samples that have already undergone centrifugation, the impact may cause the serum layer and blood cell layer to remix, making the sample unsuitable for direct testing. Summary of the Invention

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] See Figures 1-3 , Figure 1 This is one of the structural schematic diagrams of a remote sample delivery and receiving device in the embodiments of this application; Figure 2 This is a schematic diagram showing the connection between a remote sample receiving device and a transmitting device in an embodiment of this application; Figure 3This is a partial structural schematic diagram of a remote sample delivery and receiving device according to an embodiment of this application. As shown in the figure, the device includes: a main housing 100, which is internally divided into an upper cavity 110 and a lower cavity 120, which are connected by a discharge port 130. A transmission channel 140 is provided at the upper end of the main housing 100, which is connected to the upper cavity 110; and a receiving assembly disposed in the upper cavity 110. The receiving assembly includes a receiving seat 200 and a deceleration unit 300 and a detection unit 400 disposed on a connecting seat. The upper end of the receiving seat 200 is connected to the transmission channel 140. The transmitting tube 810 of the sample transmitting device 800 is connected to the receiving seat 200 through the transmission channel 140. The system is interconnected; the deceleration unit 300 is used to slow down the speed of the sample emitted through the emission tube 810; the detection unit 400 is used to detect the sample falling; the transmission component 500 is disposed at the lower end of the receiving seat 200, and a guide groove 220 is provided below the receiving seat 200, so that the sample after falling is guided from a vertical posture to a horizontal posture under the traction force of the guide groove 220 and the transmission component 500; the transmission component 500 is used to transmit the sample to the discharge port 130; the identification component 600 is disposed on the transmission path of the transmission component 500 and is used to read the barcode information on the sample; the controller 700 is electrically connected to the deceleration unit 300, the detection unit 400, the transmission component 500, the identification component 600 and the sample emission device 800 respectively. By dividing the main housing 100 into an upper cavity 110 and a lower cavity 120, and integrating a receiving component, a transmission component 500, and an identification component 600 within the upper cavity 110, the controller 700 enables centralized control of each component. The deceleration unit 300 slows down the incoming sample to prevent damage from high-speed descent; the detection unit 400 senses the sample's descent status in real time to ensure accurate triggering of subsequent actions; the transmission component 500, in conjunction with the guide groove 220, guides the sample from a vertical to a horizontal orientation, facilitating barcode reading by the identification component 600; the controller 700 is electrically connected to each component and the sample transmitting device 800, achieving fully automated closed-loop control from sample transmission to reception, identification, and descent, thus improving the reliability and efficiency of sample reception.

[0021] See Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of the structure of the receiving base 200 of a remote sample delivery receiving device in an embodiment of this application; Furthermore, in this embodiment, the receiving base 200 has a mounting groove 210 on its side, and the mounting groove 210 has an elongated hole 211 communicating with the inner cavity of the receiving base 200; the deceleration unit 300 has at least one set, and the deceleration unit 300 includes a deceleration motor 310 and a roller brush 320. The deceleration motor 310 is fixed to the opening of the mounting groove 210, and the roller brush 320 is installed at the power output end of the deceleration motor 310 and extends into the inner cavity of the receiving base 200 through the elongated hole 211. This allows a stable contact area to be formed between the roller brush 320 and the sample, which can apply uniform friction force to the high-speed falling sample, thereby achieving smooth deceleration; at the same time, the installation method of the roller brush 320 extending through the elongated hole 211 facilitates disassembly and maintenance, and multiple sets of roller brushes 320 can be set as needed to adapt to sample tubes of different weights or sizes, thus having good versatility.

[0022] See Figure 4 Preferably, the deceleration unit 300 is provided in two sets, one set is located at the upper part of the elongated hole 211, and the other set is located at the lower part of the elongated hole 211. The roller brushes 320 of the two sets of deceleration units 300 are arranged opposite each other in the vertical direction, forming a deceleration gap between them for the sample to pass through. This arrangement enables the two roller brushes 320 to apply symmetrical frictional force from both sides of the sample simultaneously, making the sample's falling trajectory stable and decelerating evenly, effectively avoiding skewing or collision caused by deceleration on one side.

[0023] See Figure 3 Furthermore, in this embodiment, the detection unit 400 includes at least one drop detection element, which is fixed to the side wall of the receiving seat 200, with its detection end extending into the inner cavity of the receiving seat 200. This allows for real-time and accurate sensing of whether the sample has fallen into place, providing a precise trigger signal to the controller 700. This ensures that the transmission component 500 and the identification component 600 start at the correct time, avoiding idling due to premature start-up or sample jamming due to delayed start-up, thus improving the system's response speed and operational stability.

[0024] Preferably, the fall detection device can be a photoelectric switch, a photoelectric sensor, or an inductive proximity switch.

[0025] See Figure 5 and Figure 6 , Figure 5 This is a second partial structural schematic diagram of a remote sample delivery and receiving device according to an embodiment of this application; Figure 6 This is a schematic diagram of the structure of the transmission component 500 of a remote sample delivery receiving device according to an embodiment of this application; Furthermore, in this embodiment, the transmission component 500 includes: a mounting base 510, fixed within the upper cavity 110 and located below the receiving seat 200; at least two transmission rollers 520, rotatably disposed within the mounting base 510, for radially transmitting samples along the transmission rollers 520; a drive motor 530, fixed to the lower end of the mounting base 510, the power output end of the drive motor 530 being connected to the two transmission rollers 520 via a transmission belt; and the drive motor 530 being electrically connected to the controller 700. This achieves stable radial transmission of the samples; the mounting base 510 is separately disposed from the receiving seat 200, facilitating modular disassembly and maintenance; and the drive motor 530 is independently controlled by the controller 700, facilitating timing linkage with other components.

[0026] Preferably, the transmission roller 520 is a spiral idler roller, which has a radially arranged spiral drive part, which is in the shape of a spiral groove. When the sample falls between the two spiral idlers, the spiral drive part generates an axial thrust on the sample, guiding it to rotate in attitude while conveying the sample. This structure achieves the attitude conversion of the sample from vertical to horizontal in a simple mechanical form, without the need for additional direction-changing mechanisms or complex controls, and is compact and inexpensive.

[0027] See Figure 5 Furthermore, in this embodiment, the identification component 600 includes: a mounting plate 610 connected to the receiving base 200, the mounting plate 610 being located above the transmission component 500 and arranged along the transmission direction of the transmission component 500; two barcode scanners 620 arranged at intervals along the transmission path of the transmission component 500; and the barcode scanners 620 being connected to the controller 700. Successful reading by either barcode scanner 620 constitutes successful identification. This redundant identification setup effectively overcomes the problem of reading failure caused by a single barcode scanner 620 due to factors such as angle deviation, lens damage, and changes in light, significantly improving the success rate of barcode identification, ensuring that sample information can be accurately obtained, and providing a reliable data foundation for subsequent information verification.

[0028] See Figure 5Furthermore, in this embodiment, the guide groove 220 is provided with a guide slope 221, which slopes from the starting end to the ending end of the transmission component 500. The guide slope 221 has an opening, and the guide groove 220 also includes a guide plate 230, which is slidably engaged within the opening to guide the sample into the lower cavity 120. The guide slope 221, which slopes from the starting end to the ending end, is provided within the guide groove 220 so that as the sample moves forward under the drive of the spiral roller, the tube gradually conforms to the slope, achieving a smooth posture transition and avoiding impacts caused by sudden posture changes. The opening on the guide slope 221 and the slidably engaged guide plate 230 allow the guide width to be adjusted according to the diameter of the sample tube, thereby adapting to sample tubes of different specifications and improving the versatility and flexibility of the device.

[0029] See Figure 1 Furthermore, in this embodiment, the controller 700 is a tablet computer, and a front panel is installed on the front of the main housing 100, with the tablet computer embedded in the front panel. The outer shell of the main housing 100 is provided with a communication interface 710 and a power interface 720, both of which are connected to the controller 700. Using a tablet computer as the controller 700, embedded in the front panel, integrates control and interactive functions, allowing operators to directly view sample information, alarm prompts, and statistical results without the need for external display devices. The communication interface 710 on the outer shell is used for data exchange with external systems, and the power interface 720 is used to connect to an external power supply. The interfaces are centrally located on the side of the outer shell, facilitating wiring and layout, and improving the ease of use of the device.

[0030] See Figure 1 and Figure 3 Furthermore, in this embodiment, the lower cavity 120 is a sample recovery chamber, and an inclined feeding plate 121 is provided inside the lower cavity 120. The feeding plate 121 is located at the lower end of the feeding port 130. A side-flipping door 150 is provided on the lower cavity 120. This allows the sample to slide down the inclined surface after falling from the feeding port 130, avoiding secondary impact caused by vertical free fall and protecting the integrity of the sample. The side-flipping door 150 on the lower cavity 120 allows operators to easily open the side-flipping door 150 to retrieve the recovered sample. The side-flipping door 150 has a large opening angle and sufficient space for retrieval, improving the ease of sample recovery operations.

[0031] Preferably, the upper edge of the side-opening door 150 is hinged to the main housing 100 via a hinge, allowing the side-opening door 150 to flip inward around the hinge axis. A magnetic latch is provided between the side-opening door 150 and the main housing 100. When the side-opening door 150 is closed, the magnetic latches engage, holding the side-opening door 150 in a closed state; when an operator pushes the side-opening door 150 inward, the magnetic attraction is overcome, and the side-opening door 150 can be opened.

[0032] See Figure 7 , Figure 7 This is a second schematic diagram of the structure of a remote sample delivery and receiving device in the embodiments of this application; Furthermore, in this embodiment, a material inlet 111 is provided on any side wall of the upper cavity 110, and the material inlet 111 is connected to the interior of the upper cavity 110. Operators can easily observe the real-time status of the sample during the receiving, deceleration, transmission, and identification processes, and promptly detect any abnormalities. When the information identified by the barcode scanner 620 is inconsistent with the sample information received by the transmitting device, the system issues an alarm, the transmission component 500 stops or maintains low-speed operation, and the operator can directly remove the abnormal sample from the upper cavity 110 through the material inlet 111.

[0033] This embodiment provides a receiving method for a remote sample delivery receiving device, including the following steps: S1: Receive sample information sent by sample transmitter 800 through controller 700 and control deceleration unit 300 to start; Specifically, before the remote delivery of the sample begins, the sample transmitting device 800 first sends the barcode information, patient information, and testing items of the sample to be sent to the controller 700 of the receiving device via network communication. The controller 700 is a tablet computer embedded in the front panel of the main housing 100, which receives the aforementioned sample information through the communication interface 710 and temporarily stores it in its internal memory. After receiving the sample information, the controller 700 immediately outputs a start signal to the deceleration unit 300. This ensures that when the sample tube arrives, the roller brush 320 of the deceleration unit 300 is already in working order, capable of applying uniform friction force to the high-speed falling sample immediately, achieving a "pre-deceleration" response.

[0034] S2: The sample launching device 800 emits a sample, which enters the receiving seat 200 through the transmission channel 140, and the deceleration unit 300 decelerates the sample uniformly. Specifically, after receiving a confirmation signal, the sample ejector 800 ejects the sample tube at high speed along the ejector tube 810. The sample tube enters the receiving assembly through the transmission channel 140 at the upper end of the main housing 100. When the sample tube falls through the deceleration gap between the two sets of roller brushes 320, the two opposing roller brushes 320 simultaneously apply opposite frictional forces from both sides of the sample tube, with the roller brushes 320 rotating in the opposite direction to the sample's falling direction. Due to the flexible material and stable rotation speed of the roller brushes 320, the sample tube experiences symmetrical and constant resistance, and its falling speed is uniformly reduced from high speed (typically 5m / s~10m / s) to low speed (approximately 0.5m / s~1m / s). This process prevents the sample tube from impacting the structure below at high speed, effectively protecting the integrity of the plasma or serum inside the sample tube and preventing the formation of air bubbles or remixing of blood cells.

[0035] S3: The falling detection device detects the sample falling and sends a trigger signal to the controller 700; Specifically, after deceleration, the sample tube continues to fall. When it passes through the detection area inside the receiving seat 200, the falling detection element fixed to the side wall of the receiving seat 200 immediately responds. The detection end of the detection element extends into the inner cavity of the receiving seat 200 to sense the passage of the sample tube. The falling detection element sends this trigger signal to the controller 700 in real time. This signal indicates that the sample tube has left the deceleration area and is about to enter the transmission component 500, providing a precise timing reference for subsequent transmission and identification actions.

[0036] S4: After receiving the trigger signal, the controller 700 starts the control transmission component 500 and the identification component 600; Specifically, the controller 700 outputs a start command to the drive motor 530 of the transmission component 500. The drive motor 530 drives two transmission rollers 520 to rotate synchronously via a transmission belt. Simultaneously, the controller 700 sends start commands to the two barcode scanners 620 of the identification component 600, causing the scanners 620 to enter either a read-reading state or a continuous scanning mode. The transmission component 500 and the guide groove 220 work together to guide the sample from a vertical orientation to a horizontal orientation and transport it forward, while the identification component 600 reads the barcode information on the sample.

[0037] This step achieves synchronous triggering of transmission and recognition, avoiding idle operation of the transmission component 500 or premature power consumption of the barcode scanner 620, and also preventing sample tube jamming or missed readings due to startup delay. The entire response time is typically in the millisecond range, ensuring that the drive roller 520 has already started operating when the sample tube just falls into it.

[0038] S5: The transmission component 500 and the guide groove 220 work together to guide the sample from a vertical orientation to a horizontal orientation and transport it forward, while the identification component 600 reads the barcode information on the sample. Specifically, the sample tube falls vertically between two drive rollers 520 under the influence of gravity. As the drive rollers 520 rotate, the helical drive unit generates an axial (i.e., transmission direction) thrust on the bottom of the sample tube. The lower end of the sample tube enters the helical drive unit first and moves forward as the drive rollers 520 rotate; the upper middle part of the sample tube initially remains vertical, but gradually comes into contact with the guide ramp 221 during movement. As the sample tube continues to move forward, the guide ramp 221 supports the tube body from one side, forcing the sample tube to gradually tilt around its lower end. When the sample tube moves to the middle and rear section of the guide groove 220, its axis has completely turned horizontal, and the entire tube body lies flat between the two helical rollers. At this time, the helical groove continues to push the sample tube to roll or slide forward in the horizontal direction.

[0039] Throughout the process of the sample tube changing from vertical to horizontal and moving forward, two barcode scanners 620 mounted above the transmission assembly 500 continuously scan the barcode on the surface of the sample tube. Once either scanner 620 successfully acquires the barcode information, it immediately sends the data to the controller 700.

[0040] S6: The controller 700 will check the barcode information read with the pre-received sample information. If they match, the controller 700 will control the transmission component 500 to send the sample into the lower cavity 120. Otherwise, the controller 700 will issue an alarm.

[0041] Specifically, the built-in software of the controller 700 compares the barcode information read in step five with the sample information received from the transmitting device in step one. The comparison includes key fields such as the sample's unique identifier (e.g., barcode number), patient ID, and test items.

[0042] If the information matches: Controller 700 determines that the remote delivery was accurate and maintains the current operating state of transmission component 500. The sample tube is continued to be pushed forward by drive roller 520, and finally leaves the upper cavity 110 through discharge port 130 and falls into the lower cavity 120. The operator can later open the side door 150 to retrieve the sample tube for subsequent testing. At the same time, controller 700 records the sample reception time, barcode information, and verification results on the tablet computer, forming a log.

[0043] If the information is inconsistent, the controller 700 immediately determines it to be abnormal. A prominent alarm prompt pops up on the tablet screen, accompanied by an audible alarm. Simultaneously, the controller 700 can choose to stop the transmission component 500 or maintain low-speed operation, awaiting manual intervention. The operator retrieves the abnormal sample tube through the material handling port 111 for manual verification and processing. The alarm event is also recorded in the controller 700 for easy traceability.

[0044] As described above, the remote sample receiving device of this invention divides the main housing into an upper cavity and a lower cavity, and integrates a receiving component, a transmission component, and an identification component in the upper cavity, with a controller to achieve centralized control of each component. The deceleration unit slows down the incoming sample to prevent damage from high-speed descent; the detection unit senses the sample's descent status in real time to ensure accurate triggering of subsequent actions; the transmission component, in conjunction with the guide groove, guides the sample from a vertical to a horizontal orientation, facilitating barcode reading by the identification component; the controller is electrically connected to each component and the sample transmitting device, realizing fully automated closed-loop control from sample transmission to reception, identification, and descent, improving the reliability and efficiency of sample reception.

[0045] This invention discloses a receiving method for a remote sample delivery receiving device. The controller pre-receives sample information and activates a deceleration unit. After the sample enters, it sequentially undergoes deceleration, detection, triggered transmission and identification, coordinated direction changing and barcode scanning, information verification, and diversion processing, forming a complete automated receiving process. This method ensures that the sample's speed is controlled, its posture is stable, and its information is traceable throughout the entire process from entering the device to falling into the recovery chamber. Furthermore, it automatically alarms when information verification is inconsistent, effectively preventing sample confusion or erroneous reception, and achieving intelligent and automated remote sample delivery reception.

[0046] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
