In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0073] The monitoring equipment can monitor various physiological parameters of the patient. There are multiple functional modules inside the monitoring equipment. Different functional modules can detect various physiological parameters of the patient and perform data conversion and data recording. For example, the non-invasive blood pressure measurement module is used to measure the patient's non-invasive blood pressure, the CO2 module is used to detect the CO2 content in the patient's breath, the AC / DC (direct current / alternating current) module is used for voltage conversion and supplies power to various boards and electrical components in the monitoring equipment, and the printing module can print the data information monitored by the monitoring equipment and the processed image information; each functional module is installed at the corresponding position inside the monitoring equipment according to its own installation requirements.

[0074] For ease of understanding, the concepts in the present invention are first defined or explained:

[0075] The term "vertical" used in this article indicates that a component is generally arranged in a vertical direction, and a certain angle with the vertical direction is allowed. The term "horizontal" is used to indicate that a component is generally arranged in a horizontal direction, and a certain angle with the horizontal direction is allowed. "Vertical" and "horizontal" are not strictly limited to being completely horizontal or completely vertical. Considering the influence of the assembly process and the use environment, when describing a component as "vertical" or "horizontal", it is allowed to have a certain angle of deflection. "Front", "back", "left" and "right" are based on the use status of the monitoring device. When the human body faces the screen of the monitoring device, the side facing the human body is the front, the side facing away from the human body is the back, the side on the left side of the human body is the left, and the side on the right side of the human body is the right.

[0076] Reference Figures 1 to 3 The monitoring device provided in the embodiment of the present invention includes a front shell component 100 and a rear shell component 200. The front shell component 100 includes a front shell 110, a screen 140 fixed on the front shell 110, a main control board 120 and a main control board mounting member 130. The screen 140 can display physiological parameters and graphics detected by various functional modules in the monitoring device. The main control board mounting member 130 and the main control board 120 are both located inside the front shell 110. The main control board 120 is mounted on the main control board mounting member 130. The main control board 120 can be a circuit board 520 integrating a main control function, a parameter function or an extended interface function. The bottom of the main control board 120 is higher than the bottom of the main control board mounting member 130. The bottom of the main control board 120 forms an installation space for the components in the monitoring device to be installed. The maximum distance between the bottom of the main control board 120 and the bottom of the main control board mounting member 130 along the height direction of the screen 140 is H1. The corresponding components and functional modules with a height not greater than H1 can be installed below the main control board 120.

[0077] Throughout the present application, the height direction along the screen 140 is the height direction commonly understood by those skilled in the art, for example, it may refer to the direction perpendicular to the top and bottom edges of the screen 140, more specifically, it may refer to the direction perpendicular to the top and bottom edges of the display area of ​​the screen 140.

[0078] Reference Figure 2The rear housing assembly 200 includes a rear housing 210 and an AC / DC module mounting member 220. The rear housing 210 is connected to the rear side of the front housing 110. The AC / DC module mounting member 220 is located inside the rear housing 210. The rear housing assembly 200 also includes a receiving compartment 230. The AC / DC module mounting member 220 is located below the receiving compartment 230. An installation space is formed between the receiving compartment 230 and the AC / DC module mounting member 220 for installation of functional modules. The distance between the AC / DC module mounting member 220 and the bottom of the receiving compartment 230 in the height direction of the screen 140 is H2. An AC / DC module having a height not greater than H2 can be installed on the AC / DC module mounting member 220 and located below the receiving compartment 230. The distance H2 here may refer to the distance between the installation surface of the AC / DC module mounting member 220 and the bottom of the receiving compartment 230 in the height direction of the screen 140.

[0079] The monitoring device further includes an AC / DC module 300 , which can perform voltage conversion and power supply. The size of the AC / DC module 300 in the height direction of the screen 140 is H, and H1<H≤H2. Since the space below the main control board 120 in the front shell 110 is insufficient to install the AC / DC module 300, in this embodiment, the AC / DC module 300 is installed on the AC / DC module mounting part 220 and is located below the accommodating compartment 230 of the rear shell assembly 200, so as to utilize the existing space in the rear shell assembly 200. Each functional module can be fully arranged in the internal space of the monitoring device, and the space below the main control board 120 can be used for the functional modules in the front shell 110 to arrange their positions. In this way, by changing the installation position and installation posture of the original functional modules in the front shell 110, the overall height of the front shell assembly 100 can be compressed, the monitoring device can be miniaturized, and the installation requirements of the AC / DC module 300 can be met, and the layout of the functional modules in the monitoring device is more reasonable; in addition, the compactness of the arrangement of components and modules in the front shell 110 is improved, which is beneficial to the overall heat dissipation of the monitoring device.

[0080] It can be understood that H2 is the distance between the mounting surface of the AC / DC module mounting member 220 for mounting the AC / DC module 300 and the bottom of the receiving compartment 230 in the height direction of the screen 140. Exemplarily, when the bottom surface of the receiving compartment 230 is a plane, and the entire mounting surface of the AC / DC module mounting member 220 for mounting the AC / DC module 300 is a plane, H2 is the distance between the bottom surface of the receiving compartment 230 and the mounting surface of the AC / DC module mounting member 220 in the height direction of the screen 140; when the bottom surface of the receiving compartment 230 or the mounting surface of the AC / DC module 300 has a concave-convex shape in the height direction of the screen 140, which is sufficient to accommodate the AC / DC module 300 in the concave-convex part, H2 is the distance between the bottom of the receiving compartment 230 and the concave-convex part of the AC / DC module mounting member 220 in the height direction of the screen 140, and H2 is greater than the size of the AC / DC module 300 in the height direction of the screen 140 at this position. H1 is the distance between the bottom of the main control board 120 and the bottom of the main control board mounting member 130 in the height direction of the screen 140. H1 is smaller than the size of the AC / DC module 300 in the height direction of the screen 140. The space between the main control board 120 and the main control board mounting member 130 in the height direction of the screen 140 is insufficient to install the AC / DC module 300.

[0081] The main control board mounting member 130 can also provide a mounting position for the functional modules disposed inside the front housing 110. Each functional module can be directly mounted on the main control board mounting member 130 without the need to additionally provide a component for mounting the functional module inside the front housing 110. The main control board mounting member 130, the main control board 120 and the screen 140 are parallel. Each functional module, such as a pump and a valve, is mounted on the main control board mounting member 130 and is located below or on the side of the main control board 120. The distance between the pump and the valve and the main control board 120 is relatively short, which facilitates the connection of the pump and the valve to the main control board 120. The main control board mounting member 130 can be specifically set as a sheet metal member, on which ribs that can be connected to the inner wall of the front shell 110 are provided for assembly and fixation of the sheet metal member and the front shell 110; in addition, since the sheet metal member is a thin sheet structure, the functional modules in the front shell 110 are directly installed using the main control board mounting member 130. When too many functional modules are installed on the main control board mounting member 130, the main control board mounting member 130 is easily deformed due to assembly factors, affecting the assembly accuracy between the components installed on the main control board mounting member 130 and other components. Therefore, installing the AC / DC module 300 in the rear shell 210 can reduce the installation load of the main control board mounting member 130 and reduce the degree of deformation of the main control board mounting member 130.

[0082] In a monitoring device provided in another embodiment of the present invention, a front shell assembly 100 includes a front shell 110, a screen 140 fixed on the front shell 110, and a main control board 120 and a main control board mounting member 130 arranged inside the front shell 110, the main control board 120 is mounted on the main control board mounting member 130, and a rear shell assembly 200 includes a rear shell 210 connected to the front shell 110 and a accommodating bin 230 arranged on the rear shell 210, a bottom wall 211 is provided at the bottom of the rear shell 210, and the accommodating bin 230 is located above the bottom wall 211 of the rear shell 210; the monitoring device also includes an AC / DC module 300, the AC / DC module 300 is arranged between the bottom wall 211 of the rear shell 210 and the accommodating bin 230, and the top of the AC / DC module 300 is higher than the bottom of the main control board 120. In this way, since the AC / DC module 300 cannot be installed below the main control board 120, the space at the height of the front shell 110 is insufficient to install the AC / DC module 300. This embodiment directly utilizes the space at the height of the accommodating bin 230 and the bottom wall 211 of the rear shell 210 to install the AC / DC module 300 in the rear shell 210, thereby reducing the number of functional modules in the front shell 110 and increasing the space margin for position change of each functional module and component in the front shell 110, which can meet the requirement of height compression of the front shell assembly 100 and miniaturize the monitoring equipment.

[0083] In addition, since the AC / DC module 300 is installed in the rear shell 210, the space in the monitoring device is reasonably utilized, the installation space in the front shell 110 is increased, and the arrangement sparseness of the components and functional modules in the front shell 110 is increased, which is beneficial to the overall heat dissipation of the monitoring device; and the AC / DC module 300 does not need to be installed on the main control board mounting member 130 in the front shell 110, which reduces the installation load of the main control board mounting member 130 and the influence on the deformation of the main control board mounting member 130.

[0084] The front shell 110 and the rear shell 210 are interlocked and form a sealed cavity therebetween to protect the functional modules and components inside the monitoring device. The storage chamber 230 can be integrally formed with the rear shell 210 to form a part of the rear shell 210, or it can be assembled on the rear shell 210. The interior of the storage chamber 230 can accommodate functional modules and provide installation for the functional modules, such as battery modules, parameter measurement accessories, IBP measurement modules, CO2 blocks, etc. The front side of the storage chamber 230 can be connected to the sealed cavity, so that the functional modules located inside the storage chamber 230 can be connected to the main control board 120.

[0085] Alternatively, the storage compartment 230 is connected to the external environment of the monitoring device, and can be used to store parameter measurement function expansion modules, medical object storage boxes, physiological parameter monitoring accessories or third-party equipment adapter modules in the monitoring device.

[0086] In one embodiment, referring to Figure 4The storage compartment 230 includes a first storage portion 231, a portion of which protrudes from the rear shell 210 toward the front shell 110, and the rear shell 210 includes a bottom wall 211. The AC / DC module 300 is arranged between the first storage portion 231 and the bottom wall 211 of the rear shell 210. The first storage portion 231 is arranged to protrude toward the front shell 110, so that the space between the front shell 110 and the rear shell 210 can be fully utilized, the storage volume of the storage compartment 230 can be increased, and the arrangement of the components in the monitoring device in the front and rear directions can be more compact, which is conducive to the miniaturization of the monitoring device; and the AC / DC module 300 located below the first storage portion 231 is closer to the front shell 110, shortening the distance between the AC / DC module 300 and the main control board 120, facilitating the connection between the AC / DC module 300 and the functional modules or components in the first storage portion 231 and the main control board 120, facilitating the wiring and reducing the mutual interference between the wires.

[0087] The first accommodating portion 231 is used to accommodate batteries, which can supply power to various functional modules in the monitoring device to ensure that the monitoring device can still operate normally when the external power supply is cut off or fails; in addition, the battery located in the first accommodating portion 231 is accommodated in the rear shell 210 and is close to the front shell 110, and can be conveniently connected to the functional modules, main control board 120, etc. set in the front shell 110 and the rear shell 210, and can take into account the power supply requirements of the functional modules in the front shell 110 and the rear shell 210 at the same time.

[0088] Reference Figure 4 and Figure 5 The storage compartment 230 further includes a second storage portion 232, which is located at the rear side of the first storage portion 231. The second storage portion 232 forms a storage cavity 233, and has a storage port 234 on the top that is connected to the storage cavity 233. The storage cavity 233 is located at the rear of the rear shell 210, and physiological parameter monitoring accessories, equipment adapter modules, etc., such as pipes and cuffs for non-invasive blood pressure measurement, and wires and connectors for power connection, etc., can be placed in the storage cavity 233 through the storage port 234. The first storage portion 231 and the second storage portion 232 are arranged in a front-to-back direction, which can make full use of the space in the front-to-back direction of the monitoring device and improve the compactness of each module and component of the monitoring device in the front-to-back direction.

[0089] In this embodiment, before the front shell 110 and the rear shell 210 are assembled, the front side of the rear shell 210 is in an open state, and the first receiving portion 231 enters the interior of the rear shell 210 from the front side of the rear shell 210, and is fixed to the front side of the second receiving portion 232 by means of threaded connection, clamping, etc. The internal cavities of the first receiving portion 231 and the second receiving portion 232 can be connected to each other, so that the battery can be replaced and repaired through the storage cavity 233. Specifically, the front side of the second receiving portion 232 is provided with an opening 235, and the first receiving portion 231 is installed on the front side of the second receiving portion 232 and connected to the opening 235, so that the storage port 234 is connected to the opening 235 through the storage cavity 233, and the user's hand can enter the storage cavity 233 from the storage port 234, and disassemble and repair the battery of the first receiving portion 231 from the rear side of the opening 235, without disassembling the monitoring device, making the later maintenance of the monitoring device more convenient.

[0090] Of course, the first accommodation portion 231 and the second accommodation portion 232 may also be integrally formed.

[0091] Furthermore, the storage compartment 230 also includes a compartment cover 236, which covers the opening 235 to shield the opening 235 and protect the battery in the first storage part 231 from being bumped or damaged due to the battery being exposed. The compartment cover 236 is installed on the side wall of the rear side of the first storage compartment 230 in a detachable manner, and the detachable manner is not limited to threaded connection, snap connection, etc. When the monitoring device is in normal operation, the compartment cover 236 covers the opening 235, and the second storage part 232 is not connected to the internal cavity of the first storage part 231. When the battery needs to be maintained, the compartment cover 236 is removed through the storage port 234 and the storage compartment to expose the battery, and the battery is in an operable state, so that the battery can be disassembled and maintained.

[0092] In another embodiment, referring to Figure 6 and Figure 7 The second accommodating portion 232 is located at the front side of the first accommodating portion 231. The second accommodating portion 232 is used to accommodate the battery. The second accommodating portion 232 is closer to the front shell 110 than the first accommodating portion 231, and can make full use of the space between the first accommodating portion 231 and the front shell 110, which is beneficial to compressing the size of the monitoring device in the front and rear directions. The battery is closer to the front shell 110, which is convenient for the battery to power the module in the front shell 110.

[0093] The specifications and dimensions of the battery are reasonably set according to the power requirements of the battery, and the inner wall of the second receiving portion 232 contacts the battery and supports and fixes the battery. The top of the second receiving portion 232 is not higher than the top of the first receiving portion 231, and the projection area formed by the first receiving portion 231 toward the plane where the screen 140 is located is larger than the projection area formed by the second receiving portion 232 toward the plane where the screen 140 is located. In this way, the bottom of the second receiving portion 232 is higher than the bottom of the first receiving portion 231, and / or the wall surface of the first receiving portion 231 in the left-right direction is protruding relative to the wall surface of the second receiving portion 232 in the left-right direction, and the space below or on the side of the second receiving portion 232 can be further used for the installation of other modules or components, thereby further improving the compactness of the arrangement of the rear shell assembly 200.

[0094] Furthermore, in the above situation, the first accommodating portion 231 is located behind the second accommodating portion 232, the first accommodating portion 231 forms a storage cavity 233, and the top has a storage port 234 connected to the storage cavity 233, and the user can insert physiological parameter monitoring accessories, device adapter modules, etc. into the storage cavity 233 through the storage port 234. It should be noted that since the second accommodating portion 232 is located at the front side of the first accommodating portion 231, it does not occupy the space at the rear side of the second accommodating portion 232, so that the second accommodating portion 232 has a larger space to set the storage cavity 233, which can improve the storage capacity of the storage cavity 233.

[0095] In this embodiment, before the front shell 110 and the rear shell 210 are assembled, the front side of the rear shell 210 is in an open state, and the second receiving portion 232 enters the interior of the rear shell 210 from the front side of the rear shell 210, and is fixed to the front side of the first receiving portion 231 by means of threaded connection, clamping, etc. The internal cavities of the first receiving portion 231 and the second receiving portion 232 can be connected to each other, so that the battery can be replaced and repaired through the storage cavity 233. Specifically, the front side of the first receiving portion 231 is provided with an opening 235, and the second receiving portion 232 is installed on the front side of the first receiving portion 231 and connected to the opening 235, so that the storage port 234 is connected to the opening 235 through the storage cavity 233, and the user's hand can enter the storage cavity 233 from the storage port 234, and disassemble and repair the battery of the second receiving portion 232 from the rear side of the opening 235, without disassembling the monitoring device, making the later maintenance of the monitoring device more convenient.

[0096] Of course, the first accommodation portion 231 and the second accommodation portion 232 may also be integrally formed.

[0097] Furthermore, the storage compartment 230 also includes a compartment cover 236, which covers the opening 235 to shield the opening 235 and protect the battery in the second storage part 232 to avoid bumping and damage due to the exposed battery. The compartment cover 236 is installed on the side wall of the front side of the first storage compartment 230 in a detachable manner, and the detachable manner is not limited to threaded connection, snap connection, etc. When the monitoring device is in normal operation, the compartment cover 236 covers the opening 235, and the second storage part 232 is not connected to the internal cavity of the first storage part 231. When the battery needs to be maintained, the compartment cover 236 is removed through the storage port 234 and the storage compartment to expose the battery, and the battery is in an operable state, so that the battery can be disassembled and maintained.

[0098] When the storage chamber 233 is provided in the storage compartment 230, the storage opening 234 at the top thereof is tilted backwards and forms an acute angle with the plane where the screen 140 is located, so that the top of the inner wall at the rear side of the storage chamber 233 is higher than the top of the inner wall at the front side of the storage chamber 233. On the one hand, when the battery is installed at the front side of the storage chamber 233, the inner wall at the front side of the first receiving portion 231 can provide a larger space for the second receiving portion 232 in the height direction, thereby increasing the space below the second receiving portion 232 for the installation of various functional modules; on the other hand, a larger support surface is provided for the accessories stored in the storage chamber 233, so that the storage of the accessories is more stable.

[0099] like Figure 2 The projection of the AC / DC module 300 on the plane perpendicular to the screen 140 at least partially overlaps with the projection of the first accommodating portion 231 on the plane perpendicular to the screen 140, so that at least a portion of the AC / DC module 300 is located directly below the first accommodating portion 231, and a portion of the AC / DC module 300 may also be located between the first accommodating portion 231 and the bottom wall 211, and exceed the front side, or the rear side, or the left side or the right side of the first accommodating portion 231. In this way, the AC / DC module 300 can make full use of the space in the front-to-back direction and the left-to-right direction in the rear shell 210.

[0100] Furthermore, the monitoring device further includes an optional module 400, which is located on one side of the AC / DC module 300 and below the storage bin 230, so that the optional module 400 and the AC / DC module 300 jointly utilize the space below the storage bin 230 to reduce space waste; the optional module 400 can be arranged on the front side, rear side, left side or right side of the AC / DC module 300, so that each module is arranged more compactly in a direction perpendicular to the screen 140, so as to effectively compress the size of the rear shell 210 and meet the miniaturization design requirements of the monitoring device. The optional module 400 can be a CO / BP expansion module, a CO / IBP expansion module, a CO2 module, etc.

[0101] The optional module 400 may also be located between one side of the storage bin 230 and the rear shell 210, and the bottom of the optional module 400 may exceed the bottom of the storage bin 230. Alternatively, the optional module 400 may be fixed to the bottom wall 211 of the rear shell 210 and located between one side of the storage bin 230 and the rear shell 210.

[0102] The rear shell assembly 200 also includes a power interface 240 installed on the rear shell 210. The power interface 240 is electrically connected to the AC / DC module 300. The external power supply can be connected to the AC / DC module 300 through the power interface 240, and the voltage is converted through AC / DC to ensure the normal operation of the monitoring device. The power interface 240 is arranged on the rear side of the rear shell 210. Preferably, the power interface 240 and the AC / DC module 300 are opposite to each other in the front-to-back direction. The AC / DC module 300 is directly connected to the power interface 240 located behind it, and the connection between the AC / DC module 300 and the power interface 240 is more convenient.

[0103] It can be understood that the AC / DC module mounting member 220 is disposed on the bottom wall 211 or the side wall of the rear shell 210, and the AC / DC module 300 can be fixed to the AC / DC module mounting member 220 by means of threaded fastening, clamping, or bonding, so that the AC / DC module 300 is firmly fixed below the accommodating compartment 230. Part of the bottom wall 211 of the AC / DC module mounting member 220 forms the AC / DC module mounting member 220, so the AC / DC module 300 can be directly mounted on the bottom wall 211 of the rear shell 210 without any other components being arranged therebetween. The accommodating compartment 230 and the AC / DC module mounting member 220 have a large space in the height direction, which can increase the installation margin of the AC / DC module 300. Alternatively, as Figure 6 The rear shell 210 includes a protrusion 213, which protrudes upward relative to the bottom wall 211 of the rear shell 210. The protrusion 213 forms an AC / DC module mounting member 220. The AC / DC module 300 is connected to the protrusion 213 by threaded connection and clamping. The bottom wall 211 supports the AC / DC module 300, and the installation of the AC / DC module 300 is more stable.

[0104] Reference Figure 8The monitoring device also includes an alarm light module 500, which can emit light. Medical staff can take rescue measures in time according to the alarm light emitted by the alarm light module 500. For example, a non-invasive blood pressure overpressure alarm, a heart rate monitoring alarm, etc. are set. When the blood pressure value measured by the non-invasive blood pressure measurement module is higher or lower than the set value, the alarm light module 500 is triggered, and the alarm light module 500 emits an alarm light. It can be understood that a speaker module 600 is also provided in the monitoring device, and the front shell 110 or the rear shell 210 has a speaker playback port. When the physiological parameters monitored by the corresponding functional modules in the monitoring device are abnormal, the speaker module 600 plays an alarm sound to alert the medical staff.

[0105] The alarm light module 500 is installed in the front shell 110, and the front shell 110 is less likely to be blocked by other facilities in the use environment, so that the light emitted by the alarm light module 500 can be dispersed in different directions, allowing medical staff to quickly locate the monitoring equipment. Fig. 9 The front shell 110 includes a front shell top wall 111 and a front shell side wall 112 connected to the front shell top wall 111. The front shell 110 also includes a light-transmitting portion 113 extending from the front shell top wall 111 to the front shell side wall 112. The light emitted by the alarm light module 500 can be emitted from the light-transmitting portion 113. In this way, the light-transmitting portion 113 is located at the corner position of the top and the side of the front shell 110. The light emitted through the light-transmitting portion 113 can be irradiated toward the top and the side of the monitoring device at the same time, expanding the visible range of the alarm light emitted by the alarm light module 500, making it convenient for medical staff to quickly find the monitoring device that emits the alarm light, and reducing the difficulty and workload of the medical staff.

[0106] The two ends of the light-transmitting portion 113 extend to the front shell top wall 111 and the front shell side wall 112, respectively. The light-transmitting portion 113 is arranged between the front shell side wall 112 and the front shell top wall 111, and the light emitted by the light-transmitting portion 113 can be emitted from the top, side and obliquely upward of the monitoring device, which can increase the angle range of the alarm light module 500. In a specific embodiment, the light-transmitting portion 113 is arranged at the upper right corner of the front shell 110, and one end of the light-transmitting portion 113 extends to the right end of the front shell top wall 111, and the other end extends to the top of the front shell side wall 112 on the right side.

[0107] The projection formed by the light-transmitting portion 113 onto a plane parallel to the screen 140 may be an arc, a fold line or a curve. Exemplarily, the light-transmitting portion 113 is set as a through hole, which connects the inner cavity of the front shell 110 with the external space, and the light emitted by the alarm light module 500 can be directly emitted through the through hole; or, the light-transmitting portion 113 may be a thin-walled structure connected between the top wall 111 of the front shell and the side wall 112 of the front shell, and the thin-walled structure can transmit light, so that the light emitted by the alarm light module 500 can be emitted; or, the light-transmitting portion 113 is set as a lens, and the light emitted by the alarm light module 500 is diverged through the lens, widening the optical path of the light, and further increasing the visible range of the alarm light.

[0108] The warning light module 500 includes a lampshade 510. The connection between the front shell top wall 111 and the front shell side wall 112 is an arc-shaped transition connection. The shape of the lampshade 510 corresponds to the arc-shaped transition connection. The arc-shaped transition between the front shell top wall 111 and the front shell side wall 112 can make the shape of the front shell 110 smoother and more regular, and reduce the degree of damage to the front shell 110 when the transition area between the two is bumped; because the shape of the lampshade 510 corresponds to the arc-shaped transition connection, the shape of the lampshade 510 is more in line with the shape of the front shell 110, and the lampshade 510 can be attached to the arc-shaped transition connection, the front shell top wall 111 and the front shell side wall 112 to a greater extent, so that the connection between the lampshade 510 and the front shell 110 is more compact, and the space occupied by the lampshade 510 in the front shell 110 can be reduced.

[0109] It should be noted that the shape of the lampshade 510 corresponds to the arc-shaped transition connection, which means that the two have approximately the same extension or bending tendency and present a generally consistent configuration; specifically, the projections of the lampshade 510 and the arc-shaped transition connection onto a plane parallel to the screen 140 are both arcs, and the arc angles are approximately the same, or, the projections of the lampshade 510 and the arc-shaped transition connection onto a plane parallel to the screen 140 are both curves, and the curvature and bending direction of the curves are approximately the same.

[0110] Reference Figure 1 The inner wall of the front shell 110 has a protruding limiting rib 114, which is located on the inner side of the front shell side wall 112 and the inner side of the front shell top wall 111. The end of the lampshade 510 abuts or is clamped on the limiting rib 114, so that the lampshade 510 is limited by the limiting rib 114 and is stably installed on the front shell 110. The limiting rib 114 surrounds the outer periphery of the lampshade 510, or a plurality of limiting ribs 114 are provided, and a plurality of limiting ribs 114 are arranged at intervals on the outer periphery of the lampshade 510. The limiting rib 114 can limit the lampshade 510 in the up-down and left-right directions at the same time, so that the installation of the lampshade 510 is more stable.

[0111] In addition, by setting the shape of the lampshade 510 to correspond to the arc-shaped transition connection, the lampshade 510 can be supported by the arc-shaped transition connection. In this way, under the joint limiting action of the arc-shaped transition connection and the limiting rib 114, the lampshade 510 is installed more stably in the front shell 110.

[0112] It can be understood that the arc-shaped transition connection, the front shell side wall 112 and the front shell top wall 111 can be connected as one piece, or the arc-shaped transition connection is assembled between the front shell side wall 112 and the front shell top wall 111, and the light-transmitting portion 113 is arranged at the arc-shaped transition connection, and the light-transmitting portion 113 can be a part of the arc-shaped transition connection, or assembled at the arc-shaped transition connection. Specifically, when the light-transmitting portion 113 is arranged as a through hole on the front shell 110, the lampshade 510 is embedded in the through hole facing a part of the front shell 110. On the one hand, the through hole is blocked to isolate the internal space of the front shell 110 from the outside and protect the internal components of the front shell 110. On the other hand, the lampshade 510 transitions in a circular ring with the arc-shaped transition connection, the front shell side wall 112 and the front shell top wall 111, so that the appearance of the front shell 110 is smoother.

[0113] Reference Fig. 9 The warning light module 500 also includes a circuit board 520 and a light source 530 electrically connected to the circuit board 520. The light source 530 is used to emit warning light. The light source 530 is arranged toward the light-transmitting portion 113. The light emitted by the light source 530 can be directly directed toward the light-transmitting portion 113, which can shorten the optical path from the light source 530 to the light-transmitting portion 113 and reduce light loss. The circuit board 520 is integrated with a light source control circuit, which can change the working state or working mode of the light source 530, such as controlling the light source 530 to emit light or stop emitting light, switching the light color of the light source 530, etc. The light source 530 can be set as an LED lamp, and the circuit board 520 is electrically connected to the main control board 120 through an electrical interface, wires, etc. According to the urgency of the alarm of the current monitoring equipment, the light source 530 can emit alarm lights of different colors under the control of the circuit board 520, so that medical staff can quickly judge and take corresponding rescue measures; multiple light sources 530 can be set and arranged at intervals. Through multi-point arrangement, the alarm light module 500 can emit light toward different positions of the light-transmitting portion 113, and the light emitted through the light-transmitting portion 113 is more uniform.

[0114] The circuit board 520 is tilted relative to the top wall 111 of the front shell and the side wall 112 of the front shell, so that the light source 530 electrically connected to the circuit board 520 is just facing the light-transmitting portion 113 located between the top wall 111 of the front shell and the side wall 112 of the front shell, and the alarm light emitted by the light source 530 can be emitted through the light-transmitting portion 113 without being blocked by the top wall 111 of the front shell and the side wall 112 of the front shell, thereby reducing light loss, and the light emitted by the light source 530 can simultaneously take into account the top and side light output of the monitoring equipment, so that the light source 530 concentrated at the corner position of the front shell 110 can emit light over a large range. On the premise of ensuring that the alarm light has a large visible range, the space occupied by the light source 530 is reduced.

[0115] It can be understood that according to the relative positions between the light-transmitting portion 113 and the front shell top wall 111 and between the light-transmitting portion 113 and the front shell side wall 112, the inclination angle of the circuit board 520 relative to the front shell top wall 111 or the circuit board 520 relative to the front shell side wall 112 can be appropriately changed so that the illumination range of the light source 530 can take into account the entire light-transmitting portion 113 and reduce the obstruction of light to the front shell top wall 111 and the front shell side wall 112.

[0116] Reference Fig.10 A recessed portion 511 recessed away from the light source 530 is provided on the side of the lampshade 510 facing the light source 530. The lampshade 510 forms an annular thin-walled structure at the recessed portion 511. The recessed portion 511 is thinner and has a good light transmission effect. The light emitted by the light source 530 first irradiates the recessed portion 511 and then radiates outward through the recessed portion 511, with high light transmittance. In addition, the light first irradiates the inner walls of different areas of the recessed portion 511 and then emits outward, which increases the divergence angle of the light irradiated outward, so that the alarm light emitted by the alarm light module 500 has a larger visible range.

[0117] The side of the lampshade 510 facing away from the light source 530 is convex and forms a convex portion 513, the concave portion 511 corresponds to the position of the convex portion 513, the light-transmitting portion 113 can be a mounting hole provided on the front shell 110, the convex portion 513 corresponds to the position of the mounting hole, and can be assembled with the mounting hole. Specifically, the convex portion 513 can be inserted into the mounting hole and can be used for the light emitted by the light source 530 to emit.

[0118] Furthermore, the light source 530 and the circuit board 520 are combined to form a light-emitting module, and are integrally assembled on the lampshade 510 to form the warning light module 500. When the warning light module 500 is assembled to the front shell 110, the light source 530 and the circuit board 520 are assembled to the lampshade 510 in advance, and the lampshade 510 cooperates with the limiting ribs 114 on the inner side of the front shell 110, so that the warning light module 500 is installed in the front shell 110. Fig. 9The lampshade 510 is provided with a circuit board fixing portion 512 for installing and fixing the circuit board 520. The circuit board fixing portion 512 is provided at both ends of the lampshade 510. The two ends of the circuit board 520 are fixed in the corresponding circuit board fixing portions 512, so that the circuit board 520 is assembled to the lampshade 510.

[0119] The circuit board fixing portion 512 may be, but is not limited to, a slot, a clamping structure, etc., provided on the lampshade 510. Exemplarily, the circuit board fixing portion 512 is provided as a groove on the lampshade 510, and the circuit board fixing portion 512 is provided at both ends of the lampshade 510, the notches of the two circuit board fixing portions 512 are arranged facing each other, the two ends of the circuit board 520 are respectively inserted into the circuit board fixing portions 512, and the circuit board 520 is clamped between the two circuit board fixing portions 512 to complete the assembly with the lampshade 510. In addition, the groove at least penetrates to the front side or the rear side of the lampshade 510, so that the circuit board 520 can be inserted into the groove in the front-to-back direction, which facilitates the assembly of the circuit board 520 to the lampshade 510.

[0120] It can be understood that since the lampshade 510 has a configuration similar to the arc-shaped transition connection, the arc-shaped transition connection protrudes away from the circuit board 520 and is constructed into an arch. After the circuit board 520 is installed between the two circuit board fixing portions 512, it is located in the internal space of the lampshade 510, and the light source 530 is located between the lampshade 510 and the circuit board 520. On the one hand, the lampshade 510 is arranged around the outside of the light source 530 to avoid light leakage. On the other hand, the circuit board 520 is installed in the internal space of the lampshade 510, so that the connection between the lampshade 510, the light source 530 and the circuit board 520 is more compact, which can reduce the volume of the alarm light module 500 and the space occupied.

[0121] Furthermore, a front wall 115 is provided on the front side of the front shell 110, and a protruding plug-in portion 214 is provided on the front side of the rear shell 210. Part of the plug-in portion 214 is inserted into the front shell 110, and the lampshade 510 is clamped between the front wall 115 and the plug-in portion 214. The alarm light module 500 is limited in the front and rear directions and is stably installed in the monitoring device. The alarm light module 500 also includes a gasket 540, which has a certain flexibility. The gasket 540 is located between the lampshade 510 and the plug-in part 214. The gasket 540 has a buffering effect to avoid hard contact between the plug-in part 214 and the lampshade 510 and the circuit board 520, and to prevent the circuit board 520 and the light source 530 from being damaged due to the squeezing of the lampshade 510 and the mounting plate by the plug-in part 214. The gasket 540 can produce a certain deformation and be in close contact with the lampshade 510 and the circuit board 520. The lampshade 510 and the circuit board 520 can be pressed between the front wall 115 and the plug-in part 214, and the installation of the alarm light module 500 is more stable. In addition, the lampshade 510 has a plug-in post 550 extending in the front-to-back direction, and the plug-in post 550 is plugged into the gasket 540 to facilitate the mutual positioning and assembly of the gasket 540 and the lampshade 510. The plug-in post 550 limits the movement of the gasket 540 relative to the lampshade 510 and the plug-in part 214, so that the gasket 540 is stably clamped between the lampshade 510 and the plug-in part 214.

[0122] In some embodiments, reference Figure 3 The front shell assembly 100 also includes a control unit 150 disposed on one side of the screen 140, and a rotary encoder 700 located below the side of the screen 140. The control unit 150 is integrated with at least one operation key 151. By operating the corresponding operation key 151, the corresponding function of the monitoring device is triggered, such as setting the home screen key, freeze key, alarm mute key, record start / pause key, cuff inflation key, etc.; the rotary encoder 700 can select the operation menu, operation parameters, etc. by rotating. The screen 140, the control unit 150 and the rotary encoder 700 can be connected to the functional module and the main control board 120 inside the monitoring device through electrical connectors such as cables and interfaces. In the scenario where the monitoring device is used to be placed on a support plane such as a desktop, the control unit 150 and the rotary encoder 700 are arranged on the side of the screen 140, which is more conducive to control.

[0123] The screen 140 is installed on the front wall 115, and the front wall 115 forms a blank area 116 below the screen 140. The size of the blank area 116 in the height direction is not less than the rotation radius of the rotary encoder 700. After the monitoring equipment is placed on the supporting plane, the distance between the screen 140 and the supporting plane can be increased, and the height of the screen 140 can be increased, so that the screen 140 is raised, which is convenient for medical staff to observe the images, videos, and data displayed on the screen 140.

[0124] The front wall 115 has a cavity that runs through the front and back, and the blank area 116 is located below the cavity. The cavity is connected to the internal space of the front shell 110. The screen 140 is embedded in the cavity.
