[0042] Embodiment

[0043] This embodiment provides a blood analysis device, as Figures 1 to 3 shown, including a receiving housing 1, a driving structure 2, a transmission structure 3, and a chord wire 4. The receiving housing 1 is a three-dimensional rectangle. An upwardly open receiving cavity 11 is provided inside the receiving housing 1, and a medium for simulating blood, such as water, can be placed in the receiving cavity 11. A plate-shaped mounting portion 12 is provided at the top of one width side of the receiving housing 1. The driving structure 2 includes a driving member 21 and a driving wheel 22. The driving member 21 is a rotating motor. The driving member 21 is fixed outside the mounting portion 12. The output end of the driving member 21 passes through the mounting portion 12 and extends horizontally toward the receiving cavity 11. The driving wheel 22 is fixed to the output end of the driving member 21, and the central axis of the driving wheel 22 coincides with the central axis of the output end of the driving wheel 22.

[0044] As Figures 1 to 3As shown in the figure, the transmission structure 3 includes a reversing bracket 31, a reversing wheel 33, a tensioning bracket 34 and a tensioning wheel 35. Grooves are provided in the middle of the driving wheel 22, the reversing wheel 33 and the tensioning wheel 35, and the string 4 is tightly attached to the bottom surface of the groove. The bottom surface of the groove is the working surface of each wheel. The annular bracket is in a "C" shape, and its two side edges are of a double-layer structure with an installation groove 32 formed therebetween. There are two reversing wheels 33, and each reversing wheel 33 is rotatably connected in an installation groove 32. The central axis of the reversing wheel 33 is perpendicular to the central axis of the driving wheel 22, and the tangent line of the working surface of the driving wheel 22 near one end of the installation groove 32 coincides with the tangent line of the working surface of the corresponding reversing wheel 33 near the driving motor. Taking the same side as an example, the corresponding tangent line at the left end of the working surface of the driving wheel 22 is a vertical line, and the tangent line of the working surface of the corresponding left reversing wheel 33 near the driving motor is also a vertical line. The two vertical lines coincide to ensure that the string 4 between the driving wheel 22 and the reversing wheel 33 is a vertical line, avoiding the string 4 at this position from shifting on the driving wheel 22 and the reversing wheel 33 or even falling off the driving wheel 22 or the reversing wheel 33.

[0045] A triangular support portion 13 is provided at the bottom of the accommodating cavity 11. The support portion 13 has an inclined support surface. The tensioning bracket 34 is plate-shaped, and the middle part of the tensioning bracket 34 is laid flat on the support surface corresponding to the support portion 13. Two tensioning wheels 35 are provided on one side of the top surface of the tensioning bracket 34 close to the reversing wheel 33. The two tensioning wheels 35 are arranged on both sides of the top surface of the tensioning bracket 34, and the two tensioning wheels 35 are arranged corresponding to the two reversing wheels 33. The tangent line of one end of the working surface of any tensioning wheel 35 away from the other tensioning wheel 35 intersects the axis of symmetry of the corresponding installation groove 32. Taking the same side as an example, the tangent line of one end of the working surface of the left tensioning wheel 35 away from the right tensioning wheel 35 is inclined upward. This tangent line is tangent to the working surface of the corresponding reversing wheel 33, and this tangent line is parallel to the top surface of the tensioning bracket 34, ensuring that the string 4 between the tensioning wheel 35 and the reversing wheel 33 is in a straight state, avoiding the string 4 at this position from shifting on the reversing wheel 33 and the tensioning wheel 35 or even falling off the reversing wheel 33 or the tensioning wheel 35.

[0046] As Figures 1 to 3 shown, the string 4 forms a closed string 4 along the outer surface of the driving wheel 22, the side of the left reversing wheel 33 close to the driving member 21, the outside of the left tensioning wheel 35, the outside of the right tensioning wheel 35 and the side of the right reversing wheel 33 close to the driving member 21, and then returns to the driving wheel 22.

[0047] When it is necessary to drive the flow of the simulated medium in the accommodation cavity 11, start the driving member 21, adjust the rotation speed of the driving member 21 according to the blood flow velocity to be simulated. The driving member 21 drives the driving wheel 22 to rotate. The driving member 21 drives the string 4 to circulate and move among the driving member 21, the reversing wheel 33 and the tensioning wheel 35 by means of friction. The driving wheel 22 winds up the string 4 to drive the water flow. The string 4 moves in the water, so that the water flow moves to simulate the blood flow. The external sensor is inserted into the water and is not allowed to touch the string 4. The external test equipment detects and records data. By controlling the rotation speed of the driving member 21, this application can simulate the blood flow conditions in different situations and has great adaptability.

[0048] The structure in this application is simple, easy to maintain, and has high applicability and practicability. In this application, the reversing bracket 31 is fixed to the accommodation housing 1 by bolts, and the tensioning bracket 34 is fixed to the support portion 13 by bolts, which is convenient for disassembly. When a component fails or is damaged, it is convenient to replace.

[0049] Such as Figures 1 to 3 As shown, the reversing wheel 33 not only plays a reversing role, but also squeezes the string 4 towards the side wall. It can make a larger part of the string 4 be under the simulated medium without the driving wheel 22 contacting the simulated medium, making it easier for the string 4 to drive the simulated medium to flow.

[0050] In this embodiment, as Figures 1 to 3 As shown, the blood analysis device further includes a shielding member 5. The shielding member 5 is U-shaped and is connected to the accommodation housing 1. There is a shielding space inside the shielding member 5. The shielding member 5 has an opening facing downwards, and the driving wheel 22 and the reversing wheel 33 are located in the shielding space. Thus, the string 4 between the driving wheel 22 and the reversing wheel 33 can also be covered in the shielding space. When the rotation speed of the driving wheel 22 is too fast, it can effectively prevent the simulated medium from splashing outwards when the string 4 flows out of the water, avoiding contamination of the desktop.

[0051] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of this utility model creation.
