Handheld monitors are smaller in size and have fewer integrated functions, and can only detect one or two parameters. When more parameter detection and wireless communication functions are integrated on handheld monitors, on the one hand, the power consumption rate of the monitor increases. In order to ensure battery life, batteries with larger cell capacity and volume need to be configured, which will increase the size of the monitor housing. On the other hand, more communication modules and parameter measurement circuits need to be integrated on the parameter board, and the area of ​​the corresponding parameter board will also increase.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. The telemetry monitor provided by the present invention has a circuit board assembly composed of a main control board, a wireless communication board and a parameter board stacked in sequence arranged in a receiving cavity of the whole machine housing. The main control board, the wireless communication board and the parameter board can all be integrated with corresponding circuit modules. The wireless communication module for realizing the wireless communication function can be separately integrated on the wireless communication board, so that there is no need to integrate the wireless communication module and the corresponding antenna on the parameter board. The wiring space on the parameter board is larger, so more types of parameter measurement circuits can be integrated to realize the diversification of the integrated functions of the telemetry monitor. Moreover, the stacking arrangement of the three-layer circuit board has a high compact structure and does not increase the thickness requirement of the receiving cavity, thus realizing the flat design of the whole machine housing. In addition, since there are many signals transmitted between the main control board and the wireless communication board, and between the wireless communication board and the parameter board, an electrical connector with multiple pins is required for electrical connection. In conventional designs, the two sides of the wireless communication board are respectively connected to the main The control board and the parameter board are electrically connected, one of the electrical connectors needs to occupy the space between the main control board and the wireless communication board, and the other electrical connector needs to occupy the space between the main control board and the wireless communication board. Since the electrical connector itself has a certain height, this design method will cause the overall height of the main control board, the wireless communication board and the parameter board to be higher after being connected through the electrical connector, thereby affecting the thickness of the entire machine housing; in the present application scheme, the first flexible flat cable is electrically connected to one side of the parameter board, and the first flexible flat cable is electrically connected to the wireless communication board through the second electrical connector after being bent, so that the first electrical connector and the second electrical connector are both located in the space between the wireless communication board and the main control board, and the spacing between the wireless communication board and the parameter board can be designed to be smaller, thereby reducing the overall height of the main control board, the wireless communication board and the parameter board after being stacked, which is conducive to reducing the thickness of the entire machine housing, and on the basis of realizing the flat and miniaturized design of the telemetry monitor, the diversification of the integrated functions of the telemetry monitor can be realized.

[0024] 2. In the telemetry monitor provided by the present invention, the ECG interface is connected to a bendable second flexible flat cable, and the blood oxygen interface is connected to a bendable third flexible flat cable. Compared with the prior art method in which the ECG interface and the blood oxygen interface are fixed on an electric connector perpendicular to the parameter board, there is no need to additionally fix the electric connector perpendicular to the parameter board on the parameter board. On the one hand, the space occupied by the electric connector in the thickness direction of the telemetry monitor is reduced, which is conducive to the flat design of the entire machine casing. On the other hand, due to the bendable characteristics of the second and third flexible flat cables, it is more convenient to install the ECG interface and the blood oxygen interface on the side wall of the rear shell assembly. In addition, the soft cable can better control the impedance, thereby improving the reliability of the telemetry monitor.

[0025] 3. In the telemetry monitor provided by the present invention, the circuit module on the wireless communication board and the parameter measurement circuit on the parameter board are arranged back to back, which increases the creepage distance between the circuit module on the wireless communication board and the parameter measurement circuit on the parameter board. Under the premise of avoiding mutual interference between circuit signals on different boards, the distance between the parameter board and the wireless communication board can be shortened as much as possible, which is conducive to realizing the flat design of the telemetry monitor.

[0026] 4. In the telemetry monitor provided by the present invention, the main control board is fixed on the front shell assembly, and the wireless communication board and the parameter board are fixed on the rear shell assembly. When the front shell assembly and the rear shell assembly are assembled, as for the assembly part of the circuit board assembly, it is only necessary to connect the main control board and the wireless communication board through the first electrical connector, which greatly simplifies the assembly complexity, reduces the assembly time, and saves space.

[0027] 5. The telemetry monitor provided by the present invention utilizes the first single-chip microcomputer minimum system circuit on the main control board to control the power supply of each circuit in the main control board, and utilizes the second single-chip microcomputer minimum system circuit on the parameter board to control the power supply of each circuit on the parameter board and the wireless communication board. This can achieve separate control of different circuits, turn off the power supply when the corresponding functions of some circuits do not need to be turned on, or control the startup of the circuit of the response function according to the use needs. This makes the control of the power supply more precise, which is beneficial to reducing power consumption and improving the endurance of the telemetry monitor. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figure 1 A telemetry monitor shown in FIG. 5 includes a housing having a housing cavity 108 therein and a circuit board assembly housed in the housing cavity 108. The housing is formed by the cooperation of a rear housing assembly 100 and a front housing assembly 200. Specifically, after the front housing assembly 200 is covered on the rear housing assembly 100, the housing is assembled by screws to form the housing of the telemetry monitor.

[0040] like Figure 1 and Figure 2 As shown, the front shell assembly 200 includes a front shell 201, a screen assembly and a sheet metal bracket 208; the front shell 201 is a plastic part, and a sunken installation area is provided in the middle of the front shell 201, and the screen assembly is embedded and installed in the installation area in the middle of the front shell 201. The screen assembly includes a touch screen 202 and a display screen 203 bonded together by optical glue; the touch screen 202 is composed of a glass cover plate and a touch screen glass, the outer side is a glass cover plate, and the inner side is a touch screen glass. The glass cover plate and the touch screen glass are bonded together by hot melt adhesive. This three-layer fully bonded screen assembly can reduce the gap between each other, thereby reducing the thickness of the entire front shell assembly 200. There is an alarm light transparent area 204 and a display area 205 on the front of the glass cover plate. The sheet metal bracket 208 is installed on the inner side of the front shell 201 and contacts the back of the display screen 203 through a conductive foam 209 to achieve the purpose of grounding the display screen 203. The sheet metal bracket 208 can also reinforce the front shell 201 to prevent the front shell 201 from deforming. In some implementations, the sheet metal bracket 208 may be omitted, and the back of the display screen 203 directly contacts the metal sheet in the front housing 201 to achieve grounding.

[0041] like Figure 1 and Figure 3 As shown, the rear shell assembly 100 includes a rear shell 101, an ECG interface 102, a blood oxygen interface 103, a probe pressure plate 104, a battery 106 and a silicone button 107.

The front shell 201 is covered on the open top surface of the rear shell 101, and the front shell 201 is fixedly connected to the rear shell 101 by screws. The rear shell 101 is a rectangular parallelepiped as a whole, the length of the rear shell 101 is greater than the width of the rear shell 101, the width of the rear shell 101 is greater than the height of the rear shell 101, the length of the rear shell 101 is approximately twice the width of the rear shell 101, and the height of the rear shell 101 is not more than 4 cm. A battery compartment 105 is provided on one side of the interior of the rear shell 101, and a battery 106 is detachably installed in the battery compartment 105. The battery 106 is an integrated battery, and the cell capacity of the battery 106 is 4000mAh. The battery 106 is directly buckled into the battery compartment 105 and connected to the battery connector 111 to power the whole device. The volume of the space occupied by the battery compartment 105 inside the rear shell 101 is greater than half of the total volume of the interior space of the rear shell 101, and completely occupies the lower half of the interior space of the rear shell 101. The space of the rear shell 101 not occupied by the battery compartment 105 is the accommodating cavity 108, and the circuit board assembly, the ECG interface 102 and the blood oxygen interface 103 are all installed in the accommodating cavity 108. An ECG interface mounting hole and a blood oxygen interface mounting hole are provided on one side of the rear shell 101 away from the battery compartment 105. The ECG interface 102 is installed on the ECG interface mounting hole, and the blood oxygen interface 103 is installed on the blood oxygen interface mounting hole. The parts of the ECG interface 102 and the blood oxygen interface 103 located in the accommodating cavity 108 are pressed with a probe pressing plate 104, which is fixed to the rear shell 101 by screws to fix the position of the ECG interface 102 and the blood oxygen interface 103. A button mounting hole is provided on the other side of the rear shell 101 corresponding to the accommodating cavity 108, and a silicone button 107 is installed on the button mounting hole.

[0042] like Figure 1 and Figure 4As shown, the circuit board assembly includes a main control board 310, a wireless communication board 320 and a parameter board 330 which are stacked in sequence from the front shell 201 to the rear shell 101 in the accommodating cavity 108. The main control board 310 is integrated with a first single-chip microcomputer minimum system circuit 311, which is used to control and drive other peripheral circuits to realize human-machine interaction functions. The power supply of each circuit in the main control board 310 can be controlled on and off by the first single-chip microcomputer minimum system circuit 311; the wireless communication board 320 is integrated with multiple wireless communication modules, which are used to realize remote communication; the parameter board 330 is integrated with multiple parameter measurement circuits, which are used to realize parameter measurement functions; and a first flexible flat cable 335 is electrically connected to one side of the parameter board 330. The main control board 310 is electrically connected to the wireless communication board 320 via the first electrical connector 350 , and the first flexible flat cable 335 is bent toward the side of the wireless communication board 320 facing away from the parameter board 330 and then electrically connected to the wireless communication board 320 via the second electrical connector 360 .

[0043] Specifically, the main control board 310, the wireless communication board 320 and the parameter board 330 are all hard PCB boards, and the first flexible flat cable 335 is a flexible circuit board with a circuit inside and can be bent. The first electrical connector 350 includes a first electrical connector socket 351 welded and fixed on the side of the wireless communication board 320 facing the main control board 310, and a first electrical connector pin 352 welded and fixed on the side of the main control board 310 facing the wireless communication board 320, and the first electrical connector pin 352 is plugged and matched with the first electrical connector socket 351.

It can be understood here that the positions of the electrical connector pin and the electrical connector socket can be interchangeably set. In an alternative embodiment, the wireless communication board 320 or the main control board 310 can also be electrically connected via a bendable flexible cable, one end of the flexible cable is electrically connected to the electrical connector socket / electrical connector pin on the wireless communication board 320, and the other end of the flexible cable is electrically connected to the electrical connector socket / electrical connector pin on the main control board 310.

[0044] This telemetry monitor has a circuit board assembly consisting of a main control board 310, a wireless communication board 320 and a parameter board 330 stacked in sequence arranged in the housing cavity 108 of the entire housing. The main control board 310, the wireless communication board 320 and the parameter board 330 can all be integrated with corresponding circuit modules. The wireless communication module for realizing the wireless communication function can be separately integrated on the wireless communication board 320, so that there is no need to integrate the wireless communication module and the corresponding antenna on the parameter board 330. The wiring space on the parameter board 330 is larger, so more types of parameter measurement circuits can be integrated to realize the diversification of the integrated functions of the telemetry monitor. Moreover, the stacking arrangement of the three-layer circuit board has a high compact structure and does not increase the volume requirement for the housing cavity 108, thereby realizing a miniaturized design of the entire housing. In addition, since there are many signals transmitted between the main control board 310 and the wireless communication board 320, and between the wireless communication board 320 and the parameter board 330, an electrical connector with multiple pins is required for electrical connection. In conventional design, the two sides of the wireless communication board 320 are electrically connected to the main control board 310 and the parameter board 330 through electrical connectors, respectively. One of the electrical connectors occupies the space between the main control board 310 and the wireless communication board 320, and the other electrical connector occupies the space between the main control board 310 and the wireless communication board 320. Since the electrical connector itself has a certain height, this design method will result in a higher overall height of the main control board 310, the wireless communication board 320 and the parameter board 330 after being connected through the two electrical connectors. Thereby affecting the thickness of the whole machine housing; in the present application scheme, the first flexible flat cable 335 is electrically connected to one side of the parameter board 330, and the first flexible flat cable 335 is bent and electrically connected to the wireless communication board 320 through the second electrical connector 360, so that the first electrical connector 350 and the second electrical connector 360 are both located in the space between the wireless communication board 320 and the main control board 310, and the spacing between the wireless communication board 320 and the parameter board 330 can be designed to be smaller, thereby reducing the overall height of the main control board 310, the wireless communication board 320 and the parameter board 330 after being stacked, which is conducive to reducing the thickness of the whole machine housing, and on the basis of realizing the flat and miniaturized design of the telemetry monitor, the diversification of the integrated functions of the telemetry monitor can be realized.

[0045] In this embodiment, the other side of the parameter board 330 is electrically connected to the second flexible flat cable 336 and the third flexible flat cable 337, the ECG interface 102 is welded and fixed on the side of the second flexible flat cable 336 facing away from the wireless communication board 320, and the blood oxygen interface 103 is welded and fixed on the side of the third flexible flat cable 337 facing away from the wireless communication board 320; after the second flexible flat cable 336 and the third flexible flat cable 337 are bent 90 degrees toward the direction of the wireless communication board 320, the ECG interface 102 and the blood oxygen interface 103 are exposed from the side wall of the rear shell 101. Compared with the prior art method in which the ECG interface 102 and the blood oxygen interface 103 are fixed on an electrical connector perpendicular to the parameter board 330, such a configuration eliminates the need to additionally fix an electrical connector perpendicular to the parameter board 330 on the parameter board 330. On the one hand, the space occupied by the electrical connector in the thickness direction of the entire machine casing is reduced, which is conducive to achieving a flat design of the entire machine casing; on the other hand, due to the bendable characteristics of the second flexible flat cable 336 and the third flexible flat cable 337, it is more convenient to install the ECG interface 102 and the blood oxygen interface 103 on the side wall of the rear shell 101; in addition, the impedance can be better controlled by the flexible flat cable, thereby improving the reliability of the telemetry monitor.

[0046] In this embodiment, the circuit module on the wireless communication board 320 is arranged on the side of the wireless communication board 320 facing away from the parameter board 330, and the parameter measurement circuit is arranged on the side of the parameter board 330 facing away from the wireless communication board 320. In this way, the creepage distance between the circuit module on the wireless communication board 320 and the parameter measurement circuit on the parameter board 330 is increased, and the distance between the parameter board 330 and the wireless communication board 320 can be reduced as much as possible under the premise of avoiding mutual interference between circuit signals on different boards, which is conducive to realizing the flat design of the whole machine housing.

[0047] In this embodiment, the main control board 310 is screwed to the front shell 201, and there are two alarm lights 317 on the main control board 310. The alarm lights 317 guide the light through the light-transmitting area 204 of the alarm lights 317 to the outside of the whole machine housing through the light-guiding silicone 206. The wireless communication board 320 and the parameter board 330 are fixed to the rear shell 101 by screws. When the front shell 200 and the rear shell assembly 100 are assembled, the assembly part of the circuit board assembly only needs to be connected to the main control board 310 and the wireless communication board 320 through the first electrical connector 350, which greatly simplifies the assembly complexity, reduces the assembly time, and saves space.

[0048] In this embodiment, the main control board 310 also integrates a touch screen driving circuit 314, a display screen display driving circuit 312, and a display screen backlight driving circuit 313 which are electrically connected to the first single-chip microcomputer minimum system circuit 311; the touch screen driving circuit 314 is electrically connected to the touch screen 202, and the display screen display driving circuit 312 and the display screen backlight driving circuit 313 are electrically connected to the display screen 203; the first single-chip microcomputer minimum system circuit 311 controls the interface touch response of the touch screen 202 through the touch screen driving circuit 314, and the first single-chip microcomputer minimum system circuit 311 controls the display content of the display screen 203 through the display screen display driving circuit 312 and the display screen backlight driving circuit 313.

[0049] The rear shell 101 is provided with a mounting groove 110, in which a speaker 109 is installed. The speaker 109 has its own spring contact pin.

[0054] In this embodiment, the parameter measurement circuit includes an ECG measurement circuit 332, a blood oxygen measurement circuit 333, and a body temperature measurement circuit 334, which are electrically connected to the second single-chip minimum system circuit 331 respectively; the ECG measurement circuit 332 is electrically connected to the external ECG lead wire 500 through the ECG interface 102, the blood oxygen measurement circuit 333 is electrically connected to the external blood oxygen probe 600 through the blood oxygen interface 103, and the body temperature measurement circuit 334 is electrically connected to the external body temperature probe 700 through the blood oxygen interface 103.

[0056] like Figure 5As shown, boost, Buck-boost, and buck are switching power supply modules for large current power supply, LDO is a small current linear regulator power supply module, and the arrow (Ctrl) represents the power control pin, which can be controlled by the first single-chip minimum system circuit 311 or the second single-chip minimum system circuit 331.

In addition, the board integration is high, the number of boards is small, the number of connecting wires is small, the assembly time is greatly reduced, and it is convenient for maintenance;

[0061] 2.
