Description

Technical Field

[0001] This invention relates to the field of medical laboratory equipment technology, and in particular to a vacuum blood collection tube signing device and equipment. Background Technology

[0002] In medical clinical testing, using vacuum blood collection tubes to collect blood samples is the most common method. After collecting blood using vacuum blood collection tubes, the information on the tubes must be verified and acknowledged to ensure that the collected blood matches the identity information of the person whose blood was drawn, thus avoiding human error. Current technology involves manually scanning the QR code on the vacuum blood collection tubes with a barcode scanner, and manually removing any erroneous tubes. This method is inefficient and prone to errors. Summary of the Invention

[0003] This invention provides a vacuum blood collection tube signing device and equipment, which realizes automated scanning of vacuum blood collection tube information, improves work efficiency, and reduces error rate.

[0004] This invention provides a vacuum blood collection tube signing device, which includes a conveyor belt driven by a belt motor for conveying vacuum blood collection tubes. The device is characterized by a viewing window baffle positioned above one end of the conveyor belt in the conveying direction. The vacuum blood collection tube and a barcode scanner are located on opposite sides of the viewing window baffle, with the rotating conveyor belt and the viewing window baffle forming an angle, and the vacuum blood collection tube rotating within this angle. The barcode scanner scans and reads barcode information in various directions around the circumference of the rotating vacuum blood collection tube through the viewing window baffle.

[0005] In this solution, when the motor drives the conveyor belt to rotate, the rotating belt and the fixed window form an angle due to the obstruction of the viewing window baffle. Driven by the friction of the belt and blocked by the smooth viewing window baffle, the vacuum blood collection tube rotates within this angle. The barcode scanner reads the markings on the vacuum blood collection tube through the viewing window and provides the information to the corresponding computer management system, which then determines whether it meets the set requirements. This achieves automated scanning of vacuum blood collection tube information, improving work efficiency and reducing the error rate.

[0006] As an improvement to the above solution, a flap driven by a flap motor is installed below the other end of the conveyor belt. If the barcode information meets the requirements, the end of the flap is close to the conveyor belt, and the conveyor belt rotating in the opposite direction transports the vacuum blood collection tube over the flap to enter the next process. If the barcode information does not meet the requirements, the end of the flap is away from the conveyor belt, forming a gap, and the conveyor belt rotating in the opposite direction transports the vacuum blood collection tube into the gap for interception. In this solution, the conveyor belt can rotate in both directions. One direction of rotation is used to scan and identify the barcode on the vacuum blood collection tube, and the other direction is used to transport and output the vacuum blood collection tube. The barcode identified by the computer system provides a control signal to determine whether the current vacuum blood collection tube enters the next process or is intercepted.

[0007] Another aspect of the present invention provides a vacuum blood collection tube signing device, which includes a frame and a support frame disposed inside the frame. The frame and the support frame are rotatably connected by a support pivot mechanism. The vacuum blood collection tube signing device is placed on the support frame. The barcode scanner is fixedly installed on the support frame by a connector. The bottom surface of the base plate of the support frame drives the support frame to rotate and swing around the support pivot mechanism through a crank swing mechanism.

[0008] In this solution, the vacuum blood collection tube signing device and the shaking mechanism are integrated into one unit. When the crank-swinging mechanism drives the vacuum blood collection tube signing device to swing, the blood and additives inside the vacuum blood collection tube are simultaneously mixed and shaken, further improving work efficiency. The barcode scanner is fixedly mounted on the support frame via a connector, ensuring that the scanner can always maintain a relatively stable scanning position with the window baffle and the vacuum blood collection tubes on the conveyor belt. Even under the swinging motion, it can still accurately scan and identify the barcode information on the vacuum blood collection tubes. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0014] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0015] Example 1

[0016] The vacuum blood collection tube receiving device 10 includes a conveyor belt 11 driven by a belt motor, a viewing window 12, and a barcode scanner 13. A viewing window 12 is positioned above one end of the conveyor belt in its conveying direction, and a flip-plate 14 driven by a flip-plate motor is positioned below the other end. When the vacuum blood collection tube 20 is placed on the conveyor belt, the vacuum blood collection tube and the barcode scanner are located on opposite sides of the viewing window 12; the vacuum blood collection tube is perpendicular to the conveyor belt's conveying direction. When the conveyor belt rotates in the opposite direction, the vacuum blood collection tube rotates against the viewing window 12, and the barcode scanner scans and reads the barcode information affixed to the vacuum blood collection tube through the viewing window 12. This information is transmitted to a host computer for interpretation, determining whether it meets the requirements, and issuing a signal to release or intercept the tube. If it is a release signal, the conveyor belt rotates in the forward direction, and the vacuum blood collection tube is conveyed out and slides down the flap to be conveyed to the next process. If it is an interception signal, the flap motor 15 drives the flap to rotate and open, so that a gap is created between the flap and the conveyor belt. The conveyor belt rotates in the forward direction, and the vacuum blood collection tube is conveyed and falls into the gap and is intercepted, falling into the collection box 16 under the support frame to prevent it from flowing into subsequent processes.

[0017] The reverse rotation of the conveyor belt can be achieved by scanning and reading the barcode information of the blood collection tube, after which the host computer will give a signal to control the motor to drive the conveyor belt to rotate in the forward direction.

[0018] The flap has a folding plate at its end, which extends close to the conveyor belt. It can connect and guide the vacuum blood collection tube into the next process, or block the guide tube from entering the collection box when the flap is open and the vacuum blood collection tube enters the gap; it has a dual guiding function.

[0019] The viewing window baffle is made of transparent material or has a see-through slit.

[0020] Example 2

[0021] This embodiment is based on Embodiment 1, and the difference between it and Embodiment 1 is as follows:

[0022] The vacuum blood collection tube signing device 30 also includes a frame 31 and a support frame 32 set inside the frame. A crossbar 33 is fixedly connected between the two opposite side walls of the frame. A groove or through groove 34 is provided in the middle of the crossbar for placing a bearing 35.

[0023] The support frame 32 includes a base plate 321 and side walls 322 disposed on opposite sides of the base plate. A shaft is disposed on the end face of the base plate on the side without side walls, which is rotatably connected to a bearing 35 on a crossbar, so that the support frame 32 can swing left and right relative to the frame 31 on both side walls 322.

[0024] A vacuum blood collection tube signing device 10 is supported on the base plate 321. The conveyor belt moves in a direction parallel to the side wall 322 of the support frame. The two ends of the viewing window baffle are fixed to the side walls of the support frame. A support plate 323 is fixedly connected to the top of the side walls of the support frame, and a barcode scanner 13 is fixedly connected to the bottom surface of the support plate. The barcode scanner is located on the side of the viewing window baffle away from the conveyor belt.

[0025] A connector 324 is fixedly connected to the bottom surface of the base plate near the side wall of the support frame. A crank-connecting rod 37 driven by a motor 36 is installed below the base plate. The output shaft of the motor is connected to a turntable 38, and one end of the crank-connecting rod is rotatably connected at a radius away from the center of the turntable. The other end of the crank-connecting rod is rotatably connected via connector 324. When the motor rotates, it drives the crank-connecting rod to rotate the base plate around the bearing, causing the support frame to oscillate repeatedly between the two side walls. The support frame then causes the vacuum blood collection tubes on the conveyor belt to oscillate, thus mixing the blood and additives within the vacuum blood collection tubes.

[0026] This device provides a post-collection monitoring and verification device and a device for mixing and shaking blood and additives for blood collection using vacuum blood collection tubes. This function can be used simultaneously or separately to meet the requirements of different operating procedures.

[0027] 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.
