Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to medical equipment technical field especially, relate to a kind of monitor with nurse calling function. BACKGROUND
[0002] Some patient monitor, vital signs monitor and other medical equipment have nurse calling function.When the data monitored reaches the alarm limit value set by user, the monitor can output signal to the nurse calling system of hospital through the cable connected to the nurse calling function interface of monitor, and call the nurse.
[0003] At present, most monitors use BNC interface or D-Sub interface to realize nurse calling function.In order to realize nurse calling function, communication interface and internal connection line in the equipment need to be added, which increases the complexity of manufacturing process and the cost of whole machine. UTILITY MODEL CONTENT
[0004] In order to solve the problems in the prior art, the present application provides a monitor with nurse calling function, so as to not need to add additional communication interface.
[0005] In order to achieve the above purpose, the present application provides a monitor with nurse calling function, which comprises a monitor body, a 5V power supply pin of a USB interface for software upgrade function in the monitor body is connected with an output pin of a control switch, an input pin of the control switch is connected with a power supply in the monitor body, and the power supply is used to output 5V power to the control switch; a control pin of the control switch is connected with a control system in the monitor body, and the control system is used to control the opening or closing of the control switch; the remaining related pins of the USB interface except the 5V power supply pin are connected with the control system, and the USB interface is used to connect USB memory or cable of nurse calling system; when the monitor is in software upgrade state, the USB interface is used to externally connect USB memory; when the monitor is in normal working state, the USB interface is connected with the cable of nurse calling system.
[0006] The monitor with nurse calling function has the advantages that the USB interface for software upgrade function commonly provided on the monitor is reused as nurse calling function interface, compared with the existing mode, no additional communication interface and corresponding internal connection line are needed, the improvement of manufacturing process complexity is avoided, the shell form does not need to be changed, and the realization is convenient. DRAWING EXPLANATION
[0007] Figure 1 The principle schematic diagram of the monitor with nurse calling function in the embodiment is shown.
[0008] Attached label: 1-USB interface, 2-control switch, 3-power supply, 4-control system. Detailed Implementation
[0009] The specific embodiments of this application will be further described below with reference to the accompanying drawings.
[0010] In the description of this application, it should be understood that the terms "first," "second," etc., are used to distinguish similar objects, rather than to describe or indicate a specific order or sequence. The terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0011] like Figure 1 As shown, the monitor with nurse call function involved in this application includes a monitor body, which is the monitor in the prior art. The 5V power supply pin of the USB interface 1 in the monitor body, which is used for software upgrade function, is connected to the output pin of the control switch 2. The input pin of the control switch 2 is connected to the power supply 3 in the monitor body. The power supply 3 is used to output 5V power to the control switch 2. The control pin of the control switch 2 is connected to the control system 4 in the monitor body, and the control system 4 controls the opening or closing of the control switch 2. The other related pins of the USB interface 1, except for its 5V power supply pin, are connected to the control system 4. The specific connection relationship is the same as the connection relationship between the USB interface 1 and the control system 4 in the prior art monitor.
[0012] When the monitor is in a software upgrade state, the USB interface 1 is used to connect an external USB memory. The control switch 2 is controlled by the control system 4 to remain in the off state. The power supply 3 supplies power to the USB interface 1, so that its 5V power supply pin continuously outputs 5V power to provide 5V power to the external USB memory, realize the normal USB interface function, and thus enable software upgrade.
[0013] When the monitor is in normal working state, the USB interface 1 is connected with the cable of the nurse call system. When the monitor opens the nurse call function, the control system 4 controls the control switch 2 according to whether there is an alarm signal, thereby controlling the output signal of the 5V power supply pin of the USB interface 1: when there is no alarm signal, the control system 4 controls the control switch 2 to be opened, and there is no 5V output on the 5V power supply pin of the USB interface 1, so the nurse call system is not triggered; when the alarm signal is activated, the control system 4 controls the control switch 2 to continuously switch between opening and closing, so that the 5V power supply pin of the USB interface 1 outputs a pulse signal with high level of 5V and low level of 0, i.e. the nurse call signal, so the nurse call system is triggered. In this way, the nurse call function is realized.
[0014] In the embodiment, the power supply 3 is a TPS62130, and outputs 5V. The control system 4 is an STM32F405, and outputs control signals. The control switch 2 is a TPS2051. The USB interface is a USB-231-BRW.
[0015] The monitor with the nurse call function disclosed in the application reuses the USB interface commonly provided on the monitor for software upgrade function as the interface for the nurse call function. Because the software upgrade function and the nurse call function cannot be used at the same time, the same USB interface can be used to realize different functions. In the application, the USB interface is reused as the nurse call interface, and the hardware foundation is built, so that the software upgrade function and the nurse call function of the monitor can be realized. Compared with the prior art, the application does not need to increase additional communication interfaces and corresponding internal connection lines, avoids the increase of manufacturing process complexity, does not need to change the shell form, and is convenient to realize.
[0016] The above is only the preferred specific embodiment of the application, but the protection scope of the application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the application within the technical range disclosed in the application, which should be covered in the protection scope of the application.
