[0019] The utility model will be described in further detail below in connection with the drawings and examples.
[0020] As Figures 1-6 shown, an intelligent analysis equipment for blood clot test and blood clot inhibition test, comprising a main body 1, wherein, the main body 1 is cuboid structure, the lower part of the main body 1 is provided with an opening, the size of the opening is matched with the size of the blood clot plate 4, the top of the main body 1 is provided with a protective cover 3, the lower surface of the protective cover 3 is provided with a groove 301, the middle part of the groove 301 is in convex form, the groove 301 uses the principle of gravity, so that the contaminated sample splashed to the lower surface of the protective cover 3 can smoothly slide along the arc-shaped groove 301, avoiding the accumulation or splashing of the sample at the top.
[0021] The inside of the main body 1 is provided with a fixed part 2, the inside of the main body 1 is connected with the fixed part 2, the outer wall lower end of the fixed part 2 and the inner wall lower end of the main body 1 are enclosed to form a collection groove 101, the collection groove 101 is in a surrounding shape, the contaminated sample falling from the groove 301 can directly fall into the collection groove 101, avoiding the sample spreading everywhere in the main body 1, the collection groove 101 plays a role in concentrating the contaminated sample, which is convenient for subsequent processing and cleaning. At the same time, it also reduces the risk of sample pollution to other parts of the main body 1, improves the overall cleanliness and safety. Through the shielding of the protective cover 3 and the guidance of the groove 301, the contaminated sample splashed to the top can smoothly slide and fall into the collection groove 101, thereby avoiding the accumulation and diffusion of the sample.
[0022] The inner wall of the fixed part 2 is attached to the outer wall of the blood clot plate 4, the inner wall of the fixed part 2 is tightly attached to the outer wall of the blood clot plate 4, ensuring the stability and firmness of the blood clot plate 4 in the fixed part 2, the fixed part 2 prevents the sample from splashing or being contaminated due to shaking or displacement of the blood clot plate 4 during the experiment to some extent, and the tight attachment also reduces the risk of sample diffusion to the surrounding environment. When blood or other potentially dangerous samples are involved, preventing the diffusion of the sample is crucial, which helps to reduce the interruption of the experiment and the error of the experimental results.
[0023] The side wall upper end of the fixed part 2 is provided with a flow guide round corner 201, which is a continuous and smooth arc surface structure. The flow guide round corner 201 extends from the outer side wall edge of the fixed part 2 and forms a round corner fit with the upper end edge of the blood clotting plate 4. The design of the flow guide round corner 201 enhances the connection strength between the fixed part 2 and the blood clotting plate 4, and also provides a smooth transition surface. At the same time, the flow guide round corner 201 guides the sample liquid splashed from the edge of the blood clotting plate 4 along the flow guide round corner 201 to the collection groove 101, further reducing the risk of sample contamination, reducing the risk of infection or injury of the experimenter, and improving the safety of the overall experimental environment. The fit design of the fixed part 2 and the blood clotting plate 4 and the setting of the flow guide round corner 201 reduce the diffusion of the sample to the surrounding environment, avoid interruption of the experiment, ensure the accuracy of the experimental results, and improve the safety of the experimental environment.
[0024] The angle between the flow direction of the flow guide round corner 201 and the direction of gravity is a, and 10°<a<45°. The main function of the flow guide round corner 201 is to guide the sample liquid that may be splashed from the edge of the blood clotting plate 4. The angle a determines the direction and speed of liquid flow. When the angle a is small (close to 10°), the liquid flow is closer to the horizontal direction, and the flow guide effect is not obvious, which may increase the risk of contaminated sample diffusing back to the blood clotting plate 4. When the angle a is large (close to 45°), the liquid flow direction is more vertical, which may increase the risk of liquid splashing. The value range of 10°<a<45° provides a reasonable selection space, which can adjust the size of the angle a according to the specific experimental requirements. By adjusting the size of the angle a, the performance of the flow guide round corner 201 in different scenarios can be optimized to ensure the smooth progress of the experiment and the accuracy of the results, which helps to reduce the risk of sample contamination and diffusion, and also improves the safety and accuracy of the experiment.
[0025] The inside of the collection groove 101 is provided with a pressure sensor, which is electrically connected to the control system. The electrical signal output by the pressure sensor is transmitted to the control system, which can determine whether the pressure change of the sample in the collection groove meets the expectations. When the pressure value detected by the pressure sensor exceeds the preset pressure threshold range, it may mean that there is a lot of waste of the sample, such as sample leakage. In this case, the experimental conditions can be adjusted in time or the sample can be collected again to ensure the accuracy and reliability of the experiment.
[0026] In the embodiment, the three balancing pads 102 are evenly distributed at the bottom of the side wall of the main body 1. The balancing pads 102 are evenly distributed at the bottom of the side wall, and no matter in which direction the main body 1 is subjected to external force, the three balancing pads 102 can reach a plane to effectively disperse and resist the force. The material of the balancing pads 102 has high anti-skid performance, which helps to prevent the main body 1 from sliding on the horizontal plane and provides certain buffering effect when subjected to slight impact, improves the overall stability of the protective cover 3 and the blood clotting plate 4, and indirectly reduces the sample splashing caused by shaking.
[0027] In the embodiment, one end of the protective cover 3 is hinged to one end of the top of the main body 1 through a hinge shaft, the other end of the protective cover 3 is clamped to the main body 1, the other end of the top of the main body 1 is provided with a clamping groove 103, and the side end of the protective cover 3 is provided with an opening device 302. The other end of the protective cover 3 is connected to the main body 1 through clamping, which ensures the stability and sealing performance of the protective cover 3 when closed. The clamping groove 103 and the corresponding clamping structure enable the protective cover 3 to be tightly attached to the main body 1, effectively preventing external contaminants from entering the inside of the main body 1. The side end of the protective cover 3 is provided with an opening device 302. The hinge and clamping design and the presence of the opening device 302 enable the experimental personnel to conveniently add samples or reagents during the experiment without interrupting the entire experimental process. Similarly, this design also facilitates the cleaning work after the experiment, and the experimental personnel can easily open the protective cover 3 to clean and disinfect the inside of the main body 1.
[0028] The above is only one of the preferred embodiments of the present application, and does not limit the form of the present application. It should be understood that for ordinary skilled persons in the art, the embodiments can be made in other forms of equivalent replacement, and within the scope of the characteristics defined by the claims, all should be included in the protection scope of the present application.
