According to the bracelet type anterior wall arterial puncture postoperative bandaging device with blood flow monitoring, provided by the embodiment of the utility model, the miniature ultrasonic blood flow detection module 401 is arranged on the lower surface of the sticking block 40, the sticking block 40 is used for being stuck to the hand of a patient tightly so as to detect the arterial blood flow at a wound through the miniature ultrasonic blood flow detection module 401, and the miniature ultrasonic blood flow detection module 401 is connected with the control circuit board 30 in a wired or wireless mode; be equipped with alarm module 301 on control circuit board 30, alarm module 301 with control module U1 connects, control module U1 passes through when miniature ultrasonic wave blood flow detection module 401 detects that the blood flow appears unusually, through alarm module 301 carries out the suggestion of reporting to the police. In this way, increased arterial blood flow may be detected when the hemostatic plate 20 is displaced from the wound. The patient is prompted by an alarm to move the hemostatic plate 20 right to seal the wound.
A resistor block 402 with a set area is fixed on the upper surface of the sticking block 40: in one embodiment of the present invention, the resistive patch 402 is a circular metal patch. The size of the circular metal block can be similar to or the same as the size of the hemostatic plate 20. The round metal block is arranged on the upper surface of the block 40. Since the patch 40 is attached to the wrist, the position of the circular metal patch is relatively fixed.
A first conductive pillar 305 and a second conductive pillar 306 are arranged on the control circuit board 30 at positions corresponding to the resistance block 402, and the first conductive pillar 305 and the second conductive pillar 306 are respectively connected with the control module U1; as shown in fig. 1 and 3, the first conductive pillar 305 and the second conductive pillar 306 are respectively located at the middle position of the circular metal block. In this way, when the bracelet housing 10 deviates, the hemostasis plate 20 and the first and second conductive pillars 305 and 306 are driven to deviate at the same time.
The control module U1 obtains the offset of the hemostasis plate 20 by the offset between the first conductive post 305 and the second conductive post 306 and the resistor block 402. When the ends of the first conductive pillar 305 and the second conductive pillar 306 are located on the upper surface of the circular metal block, the first conductive pillar 305 and the second conductive pillar 306 can be conducted with each other. The control module U1 detects that the first conductive pillar 305 and the second conductive pillar 306 are still in the conductive state, and thus the first conductive pillar 305 and the second conductive pillar 306 are not yet deviated from the circular metal block. At this point, it is illustrated that the hemostatic plate 20 is also not offset from the wound by the simultaneous offset of the first and second conductive posts 305, 306. When the first conductive pillar 305 and/or the second conductive pillar 306 are offset from the circular metal block, conduction between the first conductive pillar 305 and the second conductive pillar 306 may be disabled. When the control module U1 detects that conduction between the first conductive pillar 305 and the second conductive pillar 306 is not possible, it indicates that the first conductive pillar 305 and/or the second conductive pillar 306 have deviated from the circular metal block. Because the hemostasis board 20 moves synchronously under the action of the bracelet shell 10. This makes it possible to judge that the hemostatic plate 20 is also displaced by a corresponding distance. The corresponding distance of deviation of the hemostasis plate 20 can be obtained by the diameter size of the circular metal block. In other embodiments, the resistive patch 402 may take other shapes, such as a square back seat rectangle. In other embodiments, the resistive patch 402 includes, in addition to the first circular metal patch: a first annular metal block 4021 and a second annular metal block, wherein the first annular metal block 4021 is arranged outside the first circular metal block; the second annular metal block is arranged outside the first annular metal block 4021; the resistance values of the first circular metal block, the first annular metal block 4021 and the second annular metal block per unit length are different values. Through a plurality of metal block ring connection, each ring can be isolated through insulation, and mutual conduction is avoided. The size of the outer ring metal block can be the same as or similar to the size of the hemostatic plate 20, so that by further subdividing the metal block, a more accurate measurement of the offset distance of the first and second conductive posts 305, 306 can be achieved. Specifically, referring to fig. 5, the resistances of the metal blocks are different from each other, such as the resistance RX1, the resistance RX2, the resistance RX3, and the resistance RX4, and when the control module U1 detects different resistance values, the offset positions of the first conductive pillar 305 and the second conductive pillar 306 can be obtained. Therefore, the offset of the hemostasis plate 20 can be better quantified and displayed through a display device, and the adjustment of a patient or medical staff is facilitated. It should be noted that the circular metal block can be divided into a plurality of annular metal blocks according to actual needs, so as to measure the offset more accurately.
