[0022] 1. The telemetry monitor provided by the present invention has a circuit board assembly consisting of a main control board, a parameter board and an interface board arranged in the housing of the whole machine. The main control board, the parameter board and the interface board can all be integrated with corresponding circuit modules. The three-layer board is adopted. On the one hand, the structure is highly compact and the total area of ​​the board is large. Without increasing the volume of the overall housing, a larger number of functional circuit modules can be integrated on the circuit board assembly to achieve the diversification of the integrated functions of the telemetry monitor. On the other hand, by integrating the first single-chip microcomputer minimum system circuit on the main control board and the second single-chip microcomputer minimum system circuit on the parameter board, the power supply of each circuit in the main control board is controlled by the first single-chip microcomputer minimum system circuit, and the power supply of each circuit on the parameter board and the interface board is controlled by the second single-chip microcomputer minimum system circuit. Different circuits can be controlled separately. When the corresponding functions of some circuits do not need to be turned on, the power supply can be turned off, or the circuit startup of the response function can be controlled according to the use needs. The control of the power supply is more precise, which is conducive to reducing power consumption and improving the endurance of the telemetry monitor.

[0023] 2. The telemetry monitor provided by the present invention uses the first single-chip microcomputer minimum system circuit to independently control the touch screen control switch, display screen control switch, audio drive circuit, 4G communication module and UWB communication module on the main control board. This can achieve independent control of each circuit module on the main control board, and control the startup of the circuit of the response function according to usage needs, which is beneficial to reducing energy consumption and improving battery life.

[0024] 3. The telemetry monitor provided by the present invention uses the second single-chip computer minimum system circuit to independently control the opening and closing of the ECG measurement control switch, blood oxygen measurement control switch, body temperature measurement control switch, blood pressure measurement control switch, Sub-1G / WIFi wireless communication module control switch, and Bluetooth communication module control switch on the parameter board. The corresponding parameters can be measured and the corresponding communication mode can be selected as needed. Some circuits that do not need to be measured and communication modules that do not need to be turned on can be turned off, which is beneficial to reducing energy consumption and improving battery life.

[0025] 4. The telemetry monitor provided by the present invention uses a flexible flat cable to electrically connect the three layers of boards. Compared with the common method of connecting two adjacent layers of boards with an electrical connector, the space occupied by the electrical connector in the height direction can be reduced, and the overall height of the main control board, parameter board and interface board after stacking can be reduced, which is conducive to reducing the thickness of the whole machine housing and realizing the flat and miniaturized design of the telemetry monitor. In addition, when assembling the whole machine housing, for the assembly part of the circuit board assembly, only the main control board and the parameter board need to be connected with a second flexible flat cable, which greatly simplifies the assembly complexity, reduces the assembly time, and saves space.

[0033] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figure 1 A telemetry monitor shown in Figure 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 or buckles to form the housing of the telemetry monitor. The circuit board assembly includes a main control board 310, a parameter board 320 and an interface board 330 which are sequentially stacked in the housing cavity 108.

[0037] like Figure 1 and Figure 2 As shown, the front housing assembly 200 includes a front housing 201 and a screen assembly, and the main control board 310 is fixed to the front housing 201 by screws.

[0038] The front shell 201 is a plastic part, and a sunken installation area is provided in the middle of the front shell 201. 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, with the glass cover plate on the outside and the touch screen glass on the inside. The glass cover plate and the touch screen glass are bonded together by hot melt glue. This three-layer fully bonded screen assembly can reduce the gap between each other, thereby reducing the thickness of the entire front shell 200.

[0039] The front of the glass cover has an alarm light transmission area 204 and a display area 205. The front shell 201 is also provided with a front shell button hole 210, on which a front shell button 211 is installed, and the main control board 310 is provided with a blood pressure measurement button 318 corresponding to the position of the front shell button 211. By pressing the front shell button 211, blood pressure measurement can be triggered.

[0040] In some embodiments, the front shell assembly 200 also includes a sheet metal bracket, which is installed on the inner side of the front shell 201 and contacts the back of the display screen 203 through conductive foam to achieve the grounding purpose of the display screen 203. The sheet metal bracket can also reinforce the front shell 201 to prevent the front shell 201 from deformation.

[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 pressing plate 104, a battery 106, a silicone button 107 and a valve pump assembly.

[0042] The rear shell 101 is a shell structure with a solid bottom surface, surrounded by side surfaces and an open top surface. 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.

[0043] The overall shape of the rear shell 101 is a rectangular parallelepiped, 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 greater 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 reaches 4000 mAh. The battery 106 is directly buckled into the battery compartment 105 and connected to the battery connector 111 to power the entire 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 parameter board 320, the interface board 330, the ECG interface 102, the blood oxygen interface 103, and the valve pump assembly are all installed in the accommodating cavity 108. The parameter board 320 and the interface board 330 are respectively fixed to the rear shell 101 by screws, and the parameter board 320 is located above the interface board 330, and there is a gap between the parameter board 320 and the interface board 330.

[0044] An ECG interface mounting hole, a blood oxygen interface mounting hole and a gas nozzle mounting hole are provided on a side of the rear shell 101 away from the battery compartment 105. The ECG interface 102 is mounted on the ECG interface mounting hole, and the blood oxygen interface 103 is mounted on the blood oxygen interface mounting hole. A third flexible flat cable 3212 and a fourth flexible flat cable 3213 are connected to one side of the parameter board 320 close to the ECG interface mounting hole and the blood oxygen interface mounting hole. The ECG interface 102 is welded and fixed on a side of the third flexible flat cable 3212 facing away from the interface board 330, and the blood oxygen interface 103 is welded and fixed on a side of the fourth flexible flat cable 3213 facing away from the interface board 330. After the third flexible flat cable 3212 and the fourth flexible flat cable 3213 are bent 90 degrees toward the direction of the interface board 330, 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 320, such a configuration eliminates the need to additionally fix an electrical connector perpendicular to the parameter board 320 on the parameter board 320. 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 third flexible flat cable 3212 and the fourth flexible flat cable 3213, 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.

[0045] The valve pump assembly includes an air pump 112, two air valves 113, an air nozzle 114 and a five-way hose 115; the five-way hose 115 includes two axial openings and three side openings, the two axial openings are located at the axial ends of the five-way hose 115, and the three side openings are located on the same side of the five-way hose 115. The air pump 112 and the two air valves 113 are respectively connected to the three side openings of the five-way hose 115, and the two air valves 113 are located on the side of the air pump 112 close to the battery compartment 105. The air nozzle 114 is connected to an axial opening of the five-way hose 115 and the air nozzle 114 is stuck on the air nozzle mounting hole. Furthermore, the two air valves 113 can be partially located in the gap between the parameter plate 320 and the interface plate to make full use of the space in the accommodating cavity 108 and realize the compact design of the overall structure.

[0046] A plastic pressing plate 116 is also provided inside the rear shell 100 and is pressed on the air pump 112. The plastic pressing plate 116 can fill the gap around the air pump 112 to prevent the air pump 112 from moving up and down during operation. The ECG interface 102, the blood oxygen interface 103 and the air nozzle 114 are provided with a probe pressing plate 104 in the accommodating cavity 108. The probe pressing plate 104 is fixed to the rear shell 101 by screws, and the ECG interface 102, the blood oxygen interface 103 and the air nozzle 114 can be fixed in position.

[0047] A button mounting hole is provided on the other side of the rear shell 101 corresponding to the accommodating cavity 108, and the silicone button 107 is installed on the button mounting hole. The circuit board assembly also includes a button board 340, which is electrically connected to the interface board 330 through a third electrical connector 337. A button board bracket 117 for fixing the button circuit board 340 is also provided in the rear shell 100.

[0048] like Figure 1 As shown in FIG. 3 , the main control board 310, the parameter board 320 and the interface board 330 are all hard PCB boards, and the main control board 310, the parameter board 320 and the interface board 330 are stacked in sequence in the direction from the front shell 201 to the rear shell 101 in the accommodating cavity 108. A first flexible flat cable 336 is connected to one side of the interface board 330, and the first flexible flat cable 336 is bent toward the side of the parameter board 320 facing away from the interface board 330 and then electrically connected to the wireless parameter board 320 through the first electrical connector 350. A first flexible flat cable interface (not shown) is welded and fixed to the main control board 310, and a second flexible flat cable interface 362 is welded and fixed to the parameter board 320, and a second flexible flat cable 360 ​​is electrically connected between the first flexible flat cable interface and the second flexible flat cable interface 362.

[0049] The first electrical connector 350 includes a first electrical connector socket 351 welded and fixed to the side of the parameter board 320 facing the main control board 310, and a first electrical connector pin 352 welded and fixed to the side of the first flexible flat cable 336 facing the parameter board 320. The first flexible flat cable 336 is bent to the side of the parameter board 320 facing away from the interface board 330 so that 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. The first flexible flat cable 336 can also be connected to the interface board 330 and the parameter board 320 in a manner similar to the second flexible flat cable 360, and the second flexible flat cable 360 ​​can also be connected to the parameter board 320 and the main control board 310 in the manner of the first flexible flat cable 336.
