A test tube transport device

Abstract

This invention discloses a test tube transport device, relating to the field of medical device technology. The device includes a drive mechanism, a test tube clamping arm assembly, and a guiding mechanism. The device achieves the vertical sliding of the transport housing through the slide rails and guide blocks of the guiding unit. A servo motor and synchronous belt of the drive unit drive the transport housing to rise and fall, thereby completing the transport of the test tubes. In the test tube clamping arm assembly, the transport housing is fixed to the synchronous belt by a positioning plate and a locking plate. The spring-connected test tube clamp body is tilted for convenient and stable placement of the test tubes. In the guiding mechanism, limiting posts on the top frame and sub-frame limit the test tube clamp body. A pressing plate depresses, causing the test tube clamp body to rotate, and the top plate pushes the test tube out, which is then transported to the designated position via a test tube guide frame. This invention has a compact structure, is simple to operate, and can stably transport test tubes and achieve precise automatic positioning.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a test tube transport device. Background Technology

[0002] Currently, all specimens (including blood, urine, and body fluids) in the hospital's laboratory are automatically scanned with barcodes to record information, which facilitates the management of blood collection tubes later. Therefore, when patients have their blood collected, they need to print their name, barcode, and test items on a label in advance through the hospital's laboratory information management system. Then, medical staff will affix the label to the blood collection tube for the purpose of managing the blood collection tube information later.

[0003] Currently, the transportation of blood collection tubes has often become a bottleneck in practical operations. Traditional methods of transporting test tubes mainly rely on manual handling or the use of simple conveyor belts. This approach is not only inefficient but also prone to sample confusion or damage due to human factors, thus affecting the accuracy of test results. Furthermore, with the increasing workload of hospital laboratories, higher demands are being placed on the efficiency and accuracy of test tube transportation.

[0004] Combining the above issues, we find that existing devices on the market are difficult to avoid all of these problems simultaneously during use. Even if they can be solved, they require external tools, thus failing to achieve the desired effect. Therefore, we propose a test tube transport device. Summary of the Invention

[0005] The purpose of this invention is to provide a test tube transport device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a test tube transport device, comprising a drive mechanism, wherein the drive mechanism includes a guide unit and a drive unit, and the drive unit is disposed on the side of the guide unit;

[0007] The front of the drive mechanism is provided with a test tube clamp arm assembly, which includes a transport housing. A positioning plate is fixedly connected to the side of the transport housing. A locking plate is provided on the outside of the positioning plate. A spring is snapped into the upper end of the transport housing. A test tube clamp body is fixedly connected to the lower end of the spring. One end of the test tube clamp body is rotatably connected to the inside of the lower end of the transport housing.

[0008] The drive mechanism is provided with a guide mechanism on the upper front. The guide mechanism includes a positioning top frame, a sub-frame on the side of the positioning top frame, limit posts on the inner sides of the positioning top frame and the sub-frame, a top pressure plate fixedly connected to the upper front end of the positioning top frame, and a test tube guide frame below the top pressure plate.

[0009] Preferably, the guide unit includes a slide rail, the front of the slide rail is provided with a groove, a guide block is slidably connected inside the groove, and the positioning top frame is disposed on the upper front of the slide rail.

[0010] Preferably, a mounting plate is engaged and fixed inside the guide block, and the mounting plate has two mounting holes inside, with a lead screw inside the mounting holes.

[0011] Preferably, the guide unit includes a motor support base, a servo motor is fixedly connected inside the motor support base, a synchronous pulley is fixedly connected to the drive shaft of the servo motor, and a synchronous belt is externally connected to the synchronous pulley.

[0012] Preferably, a first track idler wheel and a second track idler wheel are provided on the left side of the first synchronous pulley. The first track idler wheel is driven to the inside of the upper end of the synchronous belt, and the second track idler wheel is driven to the bottom of the upper end of the synchronous belt.

[0013] Preferably, an upper bearing plate is installed on one side of the first and second track idlers, the synchronous belt is parallel to one side of the slide rail, the lower end of the synchronous belt is connected to a second synchronous pulley, and a lower bearing plate is installed on the outside of the second synchronous pulley.

[0014] Preferably, a mounting and positioning box is provided on the right side of the transport housing. The mounting and positioning box has two threaded holes inside, and the two lead screws pass through the threaded holes of the mounting and positioning box and are threadedly connected to the mounting holes of the mounting plate.

[0015] Preferably, the upper end of the transport housing is provided with a slot, the upper end of the spring is engaged inside the slot, the lower end of the transport housing is provided with a V-shaped rotating groove, and a top plate is fixedly connected to the bottom of the transport housing, the top plate being located below the test tube clamp body.

[0016] Preferably, the test tube clamp body has a U-shaped groove inside, the upper edge of the U-shaped groove is chamfered, and the end of the test tube clamp body has a shaft hole, which is rotatably connected to the inside of the V-shaped rotating groove through a shaft.

[0017] Preferably, the positioning plate and the locking plate are fixed together by bolts, the timing belt passes between the positioning plate and the locking plate, and the positioning plate and the locking plate are fixed to the outside of the timing belt.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, the clamping arm is tilted upwards. When the test tube falls onto the clamping arm of the test tube clamping arm assembly, it tilts upwards. Then, the servo motor drives the synchronous wheel to rotate, which in turn drives the synchronous belt to rotate. This causes the transport housing outside the synchronous belt to move upwards with the rotation of the synchronous belt, thereby driving the test tube clamp body to move upwards. The transport housing is limited by the connection between the slide rail and the slider, so that the synchronous belt drives the test tube on the test tube clamp body to move forward together. When the test tube clamp body encounters the top pressure plate, the servo motor continues to rotate, causing the test tube clamp body to slowly tilt downwards under the action of the spring. After tilting to a certain angle, the clamping arm stops moving through the positioning of the set sensor. Then the test tube can smoothly slide down and fall into the designated position. After the test tube falls, the test tube clamp body moves downwards back to the starting position of the blood collection tube, and the tube is reconnected, achieving the effect of facilitating the transport of test tubes.

[0020] 2. This invention can stably transport test tubes. Through the cooperation of the drive mechanism and the guide mechanism, it ensures the stability and accuracy of the test tubes during transportation, making it convenient to place and remove the test tubes. The inclined test tube clamp body and U-shaped groove design make it easier to place and fix the test tubes. At the same time, the chamfer setting makes the test tubes fit better and the placement more stable, realizing automatic transportation and positioning. The device can automatically transport the test tubes to the designated position, improving work efficiency. Attached Figure Description
