Description

Technical Field

[0001] This utility model relates to the field of biochemical testing technology, and in particular to a biochemical testing sampling device. Background Technology

[0002] A biochemical sampling device is a specialized instrument for extracting samples in biochemical experiments. It typically consists of a sampling needle, a sampling tube, a transport system, and a control unit. This device can accurately and quickly obtain a certain amount of blood, tissue fluid, cells, and other samples from organisms or experimental materials, ensuring that the samples are not contaminated during collection and remain in their original state, providing a reliable basis for subsequent biochemical analysis. Using this device can improve experimental efficiency and sample quality, and it is widely used in clinical diagnosis, disease research, drug development, and other fields.

[0003] Traditional biochemical testing sampling devices may lack effective fixing and support structures, which can cause errors in the sampling needle due to vibration or movement during the sampling process. In addition, traditional biochemical testing sampling devices usually have complicated installation procedures, making them inconvenient to install and disassemble, resulting in high maintenance costs and inconvenience.

[0004] Therefore, those skilled in the art have provided a biochemical testing sampling device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biochemical testing sampling device. Through the design of a fixing groove, clamping components, telescopic plate, and return spring, the device ensures the stability of the sampling needle during the sampling process, effectively reducing sampling errors caused by vibration or movement. Simultaneously, the design of the connecting plate simplifies the installation and replacement of the sampling needle, greatly reducing the workload of operators. Furthermore, the sample container, pressure pump, diversion tube, and connecting tube enable automated sample transfer, reducing manual operation steps. The design of multiple sampling needles and connecting tubes allows for simultaneous or continuous sampling of multiple samples, further improving sampling efficiency and automation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A biochemical testing sampling device includes a base plate, a workbench, and multiple sampling needles. Each of the four corners of the upper surface of the workbench has a fixing groove. Clamping components are provided at the middle of the front and rear ends of each fixing groove. A telescopic plate is fixedly connected to the middle of the outer wall of the clamping component near the center of the workbench. The telescopic plate is fixedly connected to the inner wall of the fixing groove near the center of the workbench on the side near the center of the workbench. Return springs are fixedly connected to both sides of the outer wall of the front and rear ends of the clamping component.

[0008] The above technical solution, through the design of the fixing groove, clamping parts, telescopic plate and return spring, ensures the stability of the sampling needle during the sampling process and reduces sampling errors caused by vibration or movement. In addition, the design of the connecting plate makes the installation and replacement of the sampling needle easier, reduces the labor intensity of operators and improves work efficiency.

[0011] Furthermore, a PLC control panel is fixedly connected to the middle of the outer wall at the front end of the workbench;

[0012] The above technical solution uses a PLC control panel to control the automated operation of the entire sampling device.

[0013] Furthermore, pull rings are fixedly connected to the side of the connecting plate away from the center of the workbench;

[0014] The above technical solution, through the pull ring design, makes the installation and replacement of the sampling needle easier.

[0015] Furthermore, the outer wall of the lower end of the sampling needle is covered with a protective sleeve;

[0016] The above technical solution uses a protective sleeve to cover the sampling needle, preventing external contaminants such as dust, bacteria, or chemicals from entering, thereby keeping the sampling needle clean and ensuring that the sample is not contaminated. In addition, it can prevent operators from directly contacting the sharp part of the sampling needle, reducing the risk of puncture wounds or other injuries.

[0017] Furthermore, limiters are fixedly connected to the upper surface of each fixing rod;
