[0041] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0042] Example:

[0043] See Figures 1-3 An auxiliary device for detecting nailfold microcirculation includes a base 1, a fingertip plate 2, a first side plate 3, a second side plate 4, and a linkage assembly. The base 1 has a square structure, and its interior is hollow.

[0044] A first sliding groove 5, a second sliding groove 6, and a third sliding groove 7 are provided on the base 1, wherein the second sliding groove 6 and the third sliding groove 7 are arranged on the same straight line and there is a gap between the second sliding groove 6 and the third sliding groove 7. The first sliding groove 5 is perpendicular to the second sliding groove 6, and one end of the first sliding groove 5 is located between the second sliding groove 6 and the third sliding groove 7.

[0045] The lengths of the second slide 6 and the third slide 7 are equal, while the length of the first slide 5 is greater than the length of the second slide 6.

[0046] The fingertip plate 2 is slidably disposed in the first slide groove 5, the first side plate 3 is slidably disposed in the second slide groove 6, and the second side plate 4 is slidably disposed in the third slide groove 7, and the first side plate 3 and the second side plate 4 are symmetrically disposed.

[0047] The linkage component is located inside the base 1, and the linkage component is poweredly connected to the fingertip plate 2, the first side plate 3, and the second side plate 4. When the fingertip plate 2 moves away from the second slide groove 6, the bracket can drive the second side plate 4 and the third side plate to move closer to each other. Furthermore, the movement speeds of the second side plate 4 and the third side plate are equal.

[0048] In addition, when the fingertip plate 2 is located at one end of the first slide groove 5 near the second slide groove 6, the distance between the second side plate 4 and the third side plate is at its maximum, that is, the second side plate 4 and the third side plate are located at the ends of the second slide groove and the third slide groove 7 that are far apart from each other.

[0049] During use, the patient presses the fingertip plate 2 with the tip of their ring finger, thereby driving the first side plate 3 and the second side plate 4 to move closer to their ring finger. Under continuous pressure, the first side plate 3 and the second side plate 4 clamp the patient's ring finger, thus achieving fixation.

[0050] This technical solution allows patients to adjust the pressure according to their own feelings, thereby fixing the fingers without causing excessive pressure and thus avoiding venous blood reflux.

[0051] In one specific embodiment:

[0052] The fingertip plate 2 has a crescent-shaped structure, and one concave side of the fingertip plate 2 faces the gap between the second slide groove 6 and the third slide groove 7. The first side plate 3 and the second side plate 4 have the same structure, and the middle part of the first side plate 3 has an arc-shaped surface structure that bulges out to both sides.

[0053] In this technical solution, the crescent-shaped fingertip plate 2 matches the end of the fingertip, and the protruding structure in the middle of the first side plate 3 and the second side plate 4 matches the two sides of the finger.

[0054] In another specific embodiment:

[0055] The base 1 has two guide grooves 8, which are respectively located on the sides of the second slide groove 6 and the third slide groove 7. The first side plate 3 passes through one end of the second slide groove 6 and is slidably disposed in one of the guide grooves 8, and the second side plate 4 passes through one end of the third slide groove 7 and is slidably disposed in the other guide groove 8.

[0056] In this embodiment, by setting two guide grooves 8, the movement trajectory of the first side plate 3 and the second side plate 4 is restricted, while avoiding the problem of them getting stuck in the second slide groove 6 and the third slide groove 7.

[0057] In another specific embodiment:

[0059] One end of the second rack 10 is fixedly disposed on the end of the first side plate 3 that passes through the second slide groove 6, and the second rack 10 is parallel to the second slide groove 6; one end of the third rack 11 is fixedly disposed on the end of the second side plate 4 that passes through the third slide groove 7, and the third rack 11 is parallel to the third slide groove 7.

[0060] The gear 12 is rotatably disposed inside the base 1, and the rotation axis of the gear 12 is perpendicular to both the first rack 9 and the second rack 10.

[0061] The second rack 10 and the third rack 11 are respectively meshed on two opposite sides of the gear 12, and the first rack 9 is meshed on the other side of the gear 12, so that the first rack 9, the second rack 10 and the third rack 11 are respectively meshed in three directions of the gear 12.

[0062] In this embodiment, when the patient's fingertip presses against the fingertip plate 2 and slides within the first groove 5, the first rack 9 drives the gear 12 to rotate, and the gear 12 drives the second rack 10 and the third rack 11 to move. Since the second rack 10 and the third rack 11 are respectively meshed on both sides of the gear 12, the second rack 10 and the third rack 11 move in opposite directions, thereby driving the first side plate 3 and the second side plate 4 to move in opposite directions.

[0063] If we take Figure 3 In the direction shown, when the first rack 9 is engaged on the left side of the gear 12, the second rack 10 is engaged on the top of the gear 12, and the third rack 11 is engaged on the bottom of the gear 12.

The support plate 17 is located inside the base 1, the pressure plate 18 is located on the end of the first rack 9 near the fingertip plate 2, and the two ends of the spring 16 are connected to the support plate 17 and the pressure plate 18, respectively.

[0070] Preferably, springs 16, support plates 17 and pressure plates 18 are symmetrically provided on both sides of the first rack 9.

[0071] After the patient's finger is removed from between the first side plate 3 and the second side plate 4, the fingertip plate 2, the first side plate 3 and the second side plate 4 can be directly driven to reset by the spring 16.

[0072] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
