An adjustable continuous sampling device

Abstract

The purpose of this invention is to provide an adjustable continuous sample dispensing device, relating to the field of medical device technology. Several samplers are arranged linearly and connected by a connecting part. Rotating the screw of the connecting part controls the extension and retraction of the telescopic rod, which in turn rotates the connecting rod to adjust the spacing between two samplers, adapting to the spacing of different sample tubes on different test tube racks. The amount of sample dispensed at one time can be adjusted using the plus and minus buttons on the handle. The number of rotations of the motor is controlled via the control panel, thereby controlling the distance the piston head advances, achieving quantitative sample dispensing. A trigger button on the handle allows simultaneous control of the motor rotation of several samplers via the control panel, enabling simultaneous dispensing of multiple test tubes. A single-control button on the push-pull housing disconnects the motor from the power supply, allowing selection of the number of samples to be dispensed simultaneously based on the number of sample tubes. This significantly improves dispensing efficiency, reduces the number of back-and-forth sampling operations, and reduces workload.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable continuous sample dispensing device. Background Technology

[0002] In the daily work of a medical testing laboratory, sample addition is a crucial and frequent operation. Its accuracy and efficiency directly affect the reliability of test results and the overall efficiency of the testing work.

[0003] Traditional sample addition methods mainly rely on manual application of single-channel pipettes to add samples one by one. This method can meet basic needs when dealing with a small number of samples, but with the continuous development of medical testing technology, the volume of clinical test samples is increasing day by day, especially when carrying out large-scale screening and batch sample testing, the drawbacks of traditional manual single-channel sample addition are becoming increasingly apparent.

[0004] On the one hand, the operation steps are cumbersome and highly repetitive. Each time a sample is added, the operator needs to repeatedly perform the actions of aspirating and discharging liquid, and each sample requires a complete operation. When dealing with hundreds or thousands of samples, this repetitive operation not only consumes a lot of time, but also greatly increases the workload of the operators, resulting in low work efficiency and making it difficult to meet the time requirements of large-scale sample testing.

[0005] On the other hand, prolonged, monotonous, and repetitive sampling and sample addition operations can easily lead to hand muscle fatigue in operators. Continuous hand movements and exertion can cause discomfort such as hand soreness and numbness, and even occupational strain, seriously affecting the operator's health. Furthermore, hand fatigue further increases the risk of operational errors, such as inaccurate liquid volume aspiration or deviation in sample placement, thereby reducing the accuracy of test results and posing potential risks to clinical diagnosis and treatment. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides the following technical solution:

[0007] An adjustable continuous sampling device includes a handle and a sampling assembly. The sampling assembly includes several connecting parts and several samplers, which are arranged linearly and connected to each other via connecting parts. Each connecting part includes a telescopic rod, two upper connecting rods, and two lower connecting rods. One end of each of the two upper connecting rods is rotatably connected to the two sides of the extended end of the telescopic rod, and the other end of each of the two upper connecting rods is rotatably connected to two samplers. One end of each of the two lower connecting rods is rotatably connected to the two sides of the non-extended end of the telescopic rod, and the other end of each of the two lower connecting rods is rotatably connected to two samplers. The distance between the two samplers is adjusted by extending or retracting the telescopic rod.

[0008] Furthermore, the connecting part also includes a screw rod, which is rotatably mounted on the non-extended end of the telescopic rod. The extended end of the telescopic rod is threaded onto the screw rod, and the extension and retraction of the telescopic rod is controlled by rotating the screw rod.

[0009] Furthermore, the sample dispenser includes a push-pull part, a sample dispensing cylinder, and a push-pull part, which are detachably mounted on both ends of the sample dispensing cylinder. The push-pull part includes a housing, a piston head, a lead screw, and a sliding sleeve. A cover is fixedly provided at the front end of the housing and detachably connected to the sample dispensing cylinder. The upper connecting rod and the lower connecting rod are rotatably mounted on the housing, and the front end of the handle is fixedly connected to the housing of one of the push-pull parts.

[0010] Furthermore, the lead screw is rotatably installed inside the housing, the piston head is located inside the sample filling cylinder, one end of the sliding sleeve is fixedly connected to the piston head, and the other end is slidably inserted into the housing and threaded onto the lead screw; and a motor is installed inside the housing to drive the lead screw to rotate, thereby causing the sliding sleeve to slide and moving the piston head inside the sample filling cylinder.

[0011] Furthermore, a power supply and motor connection are provided inside the housing, and a single control button is provided at the rear of the housing to control the connection status of the motor and the power supply.

[0012] Furthermore, the handle is equipped with a control panel, and a trigger button and plus / minus buttons are provided on the handle.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This invention arranges several pipettes linearly, connected by a connecting part. Rotating the screw in the connecting part controls the extension and retraction of the telescopic rod, which in turn rotates the connecting rod to adjust the spacing between two pipettes, adapting to the spacing of different test tubes on different test tube racks. The amount of sample added at one time can be adjusted using the plus / minus buttons on the handle, and the number of motor rotations can be controlled via the control panel, thereby controlling the distance the piston head advances, achieving quantitative sample addition. The trigger button on the handle allows for simultaneous control of the motor rotations of several pipettes via the control panel, enabling simultaneous addition of samples to multiple test tubes. A single-control button on the push-pull housing can disconnect the motor from the power supply, allowing selection of the number of samples to be added simultaneously based on the number of test tubes. This significantly improves sample addition efficiency, reduces the number of back-and-forth sample additions and extractions, and reduces workload. Attached Figure Description
