Description

Technical Field

[0001] The utility model relates to a bedside warning sign for patients with thrombosis, belonging to the field of medical auxiliary marking. Background Art

[0002] Currently in the healthcare field, thrombosis is a common but serious health problem that may lead to serious complications. Patients with thrombosis, especially those who need bed rest after treatment or surgery, need special care and attention, especially during ICU transitional care, to prevent recurrence of thrombosis or the development of complications.

[0003] However, in a hospital environment, medical staff and visitors may not understand the patient's special health conditions, leading to inappropriate nursing behavior or possible risks. For example, massaging a patient's legs may increase the risk of thrombosis, and medical staff or visitors may take such actions without knowing it. The existing solution is to set up a sign at the patient's bedside, such as CN210429077U-a thrombus position sign, which displays the patient's thrombus position through the sign, and controls the coloring of the sign through the injection needle, so as to avoid the problem of unclear explanation of the thrombus position. However, the inventor of this application found in the research of scientific research projects and clinical practice that the existing sign has the problem of insufficient warning when used. The existing sign can only mark the thrombus position, and cannot mark the type of thrombus. Therefore, the sign can only serve as a warning to medical staff. For accompanying personnel and visitors, due to the lack of necessary nursing knowledge, it is impossible to serve as a warning only by the coloring of the sign. Moreover, in the practice of the ICU transitional nursing plan, problems such as display position offset caused by accidental touch by accompanying personnel and visitors also occur frequently.

When the S pole of the magnet 6 is close to the sensing surface of the bipolar Hall sensor, the voltage at the output end will rise to 4.2V, and when the N pole of the magnet 6 is close to the sensing surface of the bipolar Hall sensor, the voltage at the output end will drop to 0.8V. The present application determines the comparison circuit according to the characteristics of the bipolar Hall sensor.

[0019] like Figure 3 As shown, the comparison circuit is composed of an operational amplifier 1, an operational amplifier 2, an operational amplifier 3, an XOR gate chip and an AND gate chip, wherein the in-phase input terminals of the operational amplifier 1 and the operational amplifier 2 are connected to the output terminal of the bipolar Hall sensor, the in-phase input terminal of the operational amplifier 3 is connected to the comparison power supply 1, the out-of-phase input terminal of the operational amplifier 1 is connected to the comparison power supply 2, the out-of-phase input terminal of the operational amplifier 2 is connected to the comparison power supply 3, and the out-of-phase input terminal of the operational amplifier 3 is connected to the ground, the operational amplifier 1 and the operational amplifier 2 are respectively connected to the two input terminals of the XOR gate chip, the output terminal of the XOR gate chip and the output terminal of the operational amplifier 3 are connected to the two input terminals of the AND gate chip, and the output terminal of the AND gate chip is connected to the buzzer; the buzzer is located inside the display board 1, one end of the buzzer is connected to the output end of the comparison circuit, and the other end is grounded.
