Example 2

The limb artery presser with early warning function of this embodiment is shown in Fig. 7, Fig. 8 and Fig. 9, 1-fixing device 1, first clamping device 5, second clamping device 6, torsion spring 7, rivet The structure of 8 and handle 9 is the same as that of embodiment 1, the only difference is:

The specific structure of the alarm device is as follows:

The alarm housing 11 is a transparent plastic cylindrical structure with a pressure scale. The scale can display the corresponding pressure according to the degree of spring deformation. There is an opening at the top for the alarm telescopic rod 14 to pass through, and the lower part is connected to the alarm base 12 through the annular bearing 13 .

The alarm base 12, this part is combined with the first fixing clip to form a whole, that is, it forms an integrated structure with the first fixing clip, so that the alarm is fixed on the first fixing clip.

Ring bearing 13: The connection between the alarm device and the alarm device base 12 is realized through the annular bearing 13, and this part is a ring bearing structure. The alarm housing 11 can be rotated by means of this structure to adjust the height of the alarm telescopic rod 14 .

The alarm telescopic rod 14, which is a long rod with threads, passes through the pressure scale 17, the rubber ring 16 and the alarm pressure adjustment sheet 15 which are arranged laterally in the alarm housing 11 in sequence. When the alarm housing 11 is rotated, the alarm telescopic rod 14 can cooperate with the alarm pressure adjusting sheet 15, the rubber ring 16 and the pressure scale 17 to achieve the purpose of lifting and lowering.

The alarm pressure regulating sheet 15 includes a circular plastic sheet, the left and right sides of the circular plastic sheet have symmetrical protrusions, which can be clamped on a pair of opposite grooves 18 on the inner wall of the alarm housing 11 . There is a hole in the center of the plastic sheet, and the hole is threaded. When the alarm housing 11 is rotated, since the protrusions on the left and right sides of the plastic sheet will be stuck with the groove 18, the alarm housing 11 and the alarm pressure adjusting sheet 15 will be locked. At the same time, it rotates, thereby driving the alarm telescopic rod 14 to move downward.

Rubber ring 16: It is a rubber ring that can be wrapped around the groove of the side wall of the alarm pressure regulating sheet 15. This rubber ring is tightly fitted with the inner wall of 1 to stabilize the alarm pressure regulating sheet.
