[0033] See Figure 1 、 Figure 2 and Figure 3 One embodiment of the present application provides a detection device 10 for detecting body fluids. The detection device 10 includes a first drive mechanism 100, a second drive mechanism 200, a third drive mechanism 300, a base 400, and a locking mechanism 500. The first drive mechanism 100 is disposed on the base 400, the second drive mechanism 200 is disposed on the first drive mechanism 100, the third drive mechanism 300 is disposed on the second drive mechanism 200, and the locking mechanism 500 is disposed on the second drive mechanism 200 or the base 400.

[0034] See Figure 1 、 Figure 2 and Figure 3In some embodiments, the first driving mechanism 100 includes a first driving assembly 110 and a first sliding member 120. The first driving assembly 110 and the first sliding member 120 are connected to each other, and the first sliding member 120 is slidably connected to the base 400 along the first direction (X-axis direction), so that the first sliding member 120 can slide back and forth relative to the base 400 along the first direction. Figure 1 The thick dotted arrow extending along the X-axis direction represents the motion trajectory of the first sliding member 120. For example, a slide groove may be provided on the first sliding member 120, and a slide rail may be provided on the base 400. The slide groove and the slide rail extend along the first direction and slide with each other. Therefore, through the sliding cooperation of the slide groove and the slide rail, the sliding connection relationship between the first sliding member 120 and the base 400 can be realized. The first driving assembly 110 includes a first motor 111 and a first screw rod 112. The first motor 111 is provided on the base 400. The first screw rod 112 extends along the first direction. The first screw rod 112 can be threadedly connected to the first sliding member 120 through a nut. For example, the nut can be fixed on the first sliding member 120, and the first screw rod 112 is threadedly connected to the nut. The first motor 111 is connected to one end of the first screw rod 112 so that the first motor 111 can drive the first screw rod 112 to rotate around the rotating shaft extending in the first direction. When the first screw rod 112 rotates, the rotational motion of the first screw rod 112 is converted into linear motion of the nut and the first sliding member 120 along the first direction. That is, the first screw rod 112 drives the first sliding member 120 to slide back and forth in the first direction relative to the base 400. The first screw rod 112 is a non-self-locking screw rod, which allows the first screw rod 112 to have a reasonable rotational speed, thereby reasonably increasing the sliding speed of the first sliding member 120 relative to the base 400 along the first direction.

[0035] See Figure 1 、 Figure 2 and Figure 3 In some embodiments, the second driving mechanism 200 includes a second driving assembly 210 and a second sliding member 220. The second driving assembly 210 and the second sliding member 220 are connected to each other, and the second sliding member 220 is slidably connected to the first sliding member 120 along the second direction (Y-axis direction), so that the second sliding member 220 can reciprocate relative to the first sliding member 120 along the second direction. The second direction and the first direction may be perpendicular to each other. Figure 1The thick dotted arrow extending along the Y-axis direction represents the motion trajectory of the second sliding member 220. For example, a slide groove may be provided on the second sliding member 220, and a slide rail may be provided on the first sliding member 120. The slide groove and the slide rail extend along the second direction and slide in conjunction with each other. Therefore, through the sliding conjunction of the slide groove and the slide rail, a sliding connection relationship between the second sliding member 220 and the first sliding member 120 can be achieved. The second drive assembly 210 includes a second motor 211 and a second screw rod 212. The second motor 211 is provided on the first sliding member 120. The second screw rod 212 extends along the second direction. The second screw rod 212 can be threadedly connected to the second sliding member 220 through a nut. For example, the nut can be fixed on the second sliding member 220, and the second screw rod 212 is threadedly connected to the nut. The second motor 211 is connected to one end of the second screw rod 212 so that the second motor 211 can drive the second screw rod 212 to rotate around the rotating shaft extending in the second direction. When the second screw rod 212 rotates, the rotational motion of the second screw rod 212 is converted into linear motion of the nut and the second sliding member 220 along the second direction. That is, the second screw rod 212 drives the second sliding member 220 to slide back and forth in the second direction relative to the first sliding member 120. The second screw rod 212 is a non-self-locking screw rod, which allows the second screw rod 212 to have a reasonable rotational speed, thereby reasonably increasing the sliding speed of the second sliding member 220 relative to the first sliding member 120 along the second direction.

[0036] See Figure 1 、 Figure 2 and Figure 3 In some embodiments, the locking mechanism 500 includes a locking rod 520 that extends along a third direction and can be retracted or extended in the third direction. The locking mechanism 500 is fixedly mounted on one of the second slider 220 and the base 400, and the other is provided with a locking hole 410. The locking rod 520 can be extended or retracted from the locking hole 410. For example, the locking mechanism 500 further includes a magnetic head 510. The locking rod 520 is connected to the magnetic head 510, which is fixedly disposed on the second slider 220. The magnetic head 510 drives the locking rod 520 to retract or extend through magnetic attraction. When the magnetic head 510 drives the locking rod 520 to extend, the locking rod 520 can extend into the locking hole 410 and engage with the locking hole 410. When the magnetic head 510 drives the locking rod 520 to retract, the locking rod 520 can be retracted from the locking hole 410, releasing the engagement with the locking hole 410. In other embodiments, the locking rod 520 may also be driven by a driver such as a pneumatic cylinder or a hydraulic cylinder to be extended and retracted.

[0037] Given that the magnetic head 510 is fixedly mounted on the second slider 220, when the magnetic head 510 drives the locking rod 520 to extend into the locking hole 410, the locking hole 410 effectively limits the locking rod 520 and the second slider 220, effectively preventing the second slider 220 from sliding back and forth in the second direction relative to the first slider 120, thereby securing the second slider 220 in the set position. Furthermore, the limiting effect of the second slider 220 on the first slider 120 effectively prevents the first slider 120 from sliding back and forth in the first direction relative to the base 400, thereby securing the first slider 120 in the set position.

[0038] Therefore, during the transportation of the detection device 10, the locking rod 520 can be engaged with the locking hole 410, thereby effectively limiting the first sliding member 120 and the second sliding member 220, preventing the first sliding member 120 from sliding relative to the base 400 under external impact, thereby preventing damage to the first drive assembly 110, and ultimately improving the reliability of the detection device 10. The second sliding member 220 can also be prevented from sliding relative to the first sliding member 120 under external impact, thereby preventing damage to the second drive assembly 210, further improving the reliability of the detection device 10; therefore, the locking mechanism 500 can effectively position the detection device 10 during transportation and provide effective protection. At the same time, the simple structure of the locking rod 520 and the locking hole 410 also allows the locking rod 520 and the locking hole 410 to cooperate to simultaneously limit the first slider 120 and the second slider 220, avoiding the first slider 120 and the second slider 220 being limited by different locking mechanisms 500. Instead, the first slider 120 and the second slider 220 can be limited by a common locking mechanism 500. This can reduce the number of locking mechanisms 500 used and ultimately simplify the structure of the detection device 10. It can also simplify the operation process of the locking mechanism 500, reduce the difficulty of operating the locking mechanism 500, and eliminate the need for professional personnel to operate the locking mechanism 500, thereby improving the convenience of use of the detection device 10.

[0039] See Figure 1 In some embodiments, the locking rod 520 includes a locking portion 521. The locking portion 521 can be positioned within the locking hole 410 and cooperate with the locking hole 410. The cross-sectional dimensions of the locking portion 521 gradually decrease from the end of the locking portion 521 closer to the magnetic head 510 to the end of the locking portion 521 farther from the magnetic head 510. This allows the locking portion 521 to be roughly tapered. For example, the locking portion 521 can be conical or pyramidal. By providing a tapered locking portion 521, the locking portion 521 can be more easily inserted into the locking hole 410, thereby improving the efficiency of the cooperation between the locking rod 520 and the locking hole 410, and further improving the convenience of use of the detection device 10.

[0040] See Figure 1 、 Figure 2 and Figure 3 In some embodiments, the third driving mechanism 300 includes a third driving assembly 310 and a third sliding member 320. The third driving assembly 310 and the third sliding member 320 are connected to each other, and the third sliding member 320 is slidably connected to the second sliding member 220 along the third direction (Z-axis direction), so that the third sliding member 320 can slide back and forth relative to the second sliding member 220 along the third direction. The third direction can be perpendicular to the first direction and the second direction at the same time, so the first direction, the second direction and the third direction are perpendicular to each other. Figure 1 The thick dotted arrow extending along the Z-axis direction represents the motion trajectory of the third sliding member 320. For example, a slide groove can be provided on the third sliding member 320, and a slide rail can be provided on the second sliding member 220. The slide groove and the slide rail extend along the third direction and slide with each other. Therefore, through the sliding cooperation of the slide groove and the slide rail, a sliding connection relationship between the third sliding member 320 and the second sliding member 220 can be achieved. The third driving assembly 310 includes a third motor 311 and a third screw rod 312. The third motor 311 is provided on the second sliding member 220. The third screw rod 312 extends along the third direction. The third screw rod 312 can be threadedly connected to the third sliding member 320 through a nut. For example, the nut can be fixed on the third sliding member 320, and the third screw rod 312 is threadedly connected to the nut. The third motor 311 is connected to one end of the third screw rod 312, so that the third motor 311 can drive the third screw rod 312 to rotate around the rotating shaft extending in the third direction. When the third screw rod 312 rotates, the rotational motion of the third screw rod 312 can be converted into linear motion of the nut and the third sliding member 320 along the third direction, that is, the third screw rod 312 drives the third sliding member 320 to slide back and forth relative to the second sliding member 220 along the third direction.

[0041] The third screw rod 312 can be a self-locking screw rod. In this way, when the third sliding member 320 stops moving, the self-locking effect of the third screw rod 312 and the nut can effectively prevent the third sliding member 320 from sliding relative to the second sliding member 220. Therefore, during the transportation of the detection device 10, the self-locking effect of the third screw rod 312 and the nut can effectively prevent the third sliding member 320 from sliding relative to the second sliding member 220 under the influence of external forces, thereby preventing damage to the third drive assembly 310 and ultimately improving the reliability of the detection device 10. It can also avoid the use of limiting components other than the third screw rod 312 to limit the third sliding member 320, that is, reduce the number of limiting components used, thereby simplifying the structure of the detection device 10.

[0042] See Figure 2 、 Figure 3 and Figure 4In some embodiments, the detection device 10 further includes an infusion tube 600 and a flexible sleeve 710. The infusion tube 600 is disposed on the third slider 320. Given that the second slider 220 is disposed on the first slider 120 and the third slider 320 is disposed on the second slider 220, when the first slider 120 slides relative to the base 400 in a first direction, the infusion tube 600, the third slider 320, and the second slider 220 will slide synchronously with the first slider 120 in the first direction. When the second slider 220 slides relative to the first slider 120 in a second direction, the infusion tube 600 and the third slider 320 will slide synchronously with the second slider 220 in the second direction. When the third slider 320 slides relative to the second slider 220 in a third direction, the infusion tube 600 will slide synchronously with the third slider 320 in the third direction. Therefore, the infusion tube 600 can have three degrees of freedom of linear motion in the first, second, and third directions. The infusion tube 600 can be accurately moved to a desired position by the movement of the first sliding member 120, the second sliding member 220, and the third sliding member 320. The infusion tube 600 extends along the third direction, and the flexible sleeve 710 can be fixed to the base 400. The flexible sleeve 710 is provided with a socket 711. When the third sliding member 320 moves closer to the flexible sleeve 710, the infusion tube 600 can be inserted into the socket 711.

[0043] During transportation of the detection device 10, when the locking rod 520 engages with the locking hole 410, the infusion tube 600 can be inserted into the insertion hole 711 of the flexible sleeve 710. On the one hand, the flexible sleeve 710 can limit one end of the infusion tube 600, preventing the infusion tube 600 from deflecting and bending under the influence of external impact, ensuring that the end of the infusion tube 600 can transport liquid at the designated position, thereby improving the reliability of the detection device 10. On the other hand, it can seal and protect the end opening of the infusion tube 600, thereby preventing foreign dust and other impurities from entering the infusion tube 600 through the end opening of the infusion tube 600 and causing blockage, ensuring that the infusion tube 600 can smoothly transport liquid during the next use, thereby further improving the reliability of the detection device 10. On the other hand, the insertion hole 711 can also collect residual liquid that may be discharged from the infusion tube 600, that is, it collects the residual liquid, preventing the residual liquid from contaminating and corroding other components of the detection device 10, and also improving the reliability of the detection device 10.

[0044] See Figure 4 and Figure 5In some embodiments, the flexible sleeve 710 can be made of a flexible silicone material and include a raised ring 712. The raised ring 712 is radially projecting from the inner wall of the insertion hole 711, extending a certain height relative to the inner wall of the insertion hole 711. The raised ring 712 can be positioned over the infusion tube 600. The diameter of the insertion hole 711 can be slightly larger than the outer diameter of the infusion tube 600. The provision of the raised ring 712 allows the raised ring 712 to be positioned over the infusion tube 600, exerting a certain tightening force on the infusion tube 600 and improving the positioning accuracy of the infusion tube 600. Furthermore, the raised ring 712 prevents the infusion tube 600 from contacting the inner wall of the insertion hole 711, allowing the infusion tube 600 to contact only the end of the raised ring 712. This reduces friction between the infusion tube 600 and the flexible sleeve 710. On the other hand, the space enclosed by the convex ring 712 can form an interference fit with the infusion tube 600, thereby effectively sealing the tube opening of the infusion tube 600. The thickness of the convex ring 712 gradually decreases from the end of the convex ring 712 close to the inner wall to the end of the convex ring 712 away from the inner wall. This also makes the convex ring 712 roughly conical, so that the convex ring 712 has a good guiding effect, which can reduce the resistance of the infusion tube 600 during the insertion and withdrawal of the socket 711, and improve the convenience of use of the detection device 10. The number of convex rings 712 can be multiple, and the multiple convex rings 712 are arranged at intervals along the axial direction of the socket 711. For example, the number of convex rings 712 can be two, etc. By providing multiple convex rings 712, the positioning ability of the convex rings 712 on the infusion tube 600 can be reasonably improved. An inner chamfer 7111 is formed at one end of the insertion hole 711 facing the third sliding member 320 . The guiding effect of the inner chamfer 7111 facilitates smooth insertion of the input tube into the insertion hole 711 , thereby improving the convenience of use of the detection device 10 .

[0045] See Figure 6In some embodiments, the detection device 10 further includes a guide post 720. The guide post 720 is fixedly connected to one of the base 400 and the third sliding member 320, and the other defines a guide hole 321. The guide post 720 can mate with the guide hole 321 and extend along the third direction. For example, one end of the guide post 720 can be fixed to the base 400, while the other end is free. The guide hole 321 is provided on the third sliding member 320. As the third slider 320 slides closer to the flexible sleeve 710, the guide post 720 can be first inserted into the guide hole 321. The guiding effect of the guide post 720 improves the movement accuracy of the third slider 320 in the third direction. This allows the infusion tube 600 to be accurately aligned with the insertion hole 711 and smoothly inserted into the insertion hole 711, avoiding the infusion tube 600 from being unable to be inserted into the insertion hole 711 and preventing the infusion tube 600 from being damaged by a hard collision with the base 400, thereby further improving the reliability of the detection device 10. Of course, to make it easier for the guide post 720 to mate with the guide hole 321, the end of the guide post 720 can be provided with an outer chamfer, so that the end of the guide post 720 is tapered and easier to insert into the guide hole 321.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
