Background

The monitor is a conventional medical device, and is widely applied to monitoring vital sign parameters of patients, such as electrocardio, blood pressure, respiration and other parameters, so as to provide timely and accurate feedback of physiological states of patients for medical staff. When the parameters are abnormal, the monitor can send alarm information to remind medical personnel to carry out timely treatment and rescue. Wherein, the alarm lamp integrated on the monitor is a conventional alarm mode.

Referring to fig. 1 and 2, a front perspective view and a rear perspective view of a monitor 100 in some embodiments of the utility model are shown, respectively. The housing of the monitor 100 includes a plurality of walls including a front wall 110 and a rear wall 120. The walls enclose a cavity structure. The cavity structure can be used to house various electrical components of the monitor 100. Any of the walls may be any shape, such as square, rectangular, or other shape, so as to generally surround the monitor 100 in a desired configuration. In some embodiments, the plurality of walls may include upper and lower sidewalls and left and right sidewalls in addition to the front sidewall 110 and the rear sidewall 120, which are not described herein again.

Monitors are typically provided with visualization means for the user to visually observe the parameters acquired by the monitor. The monitor 100 shown in fig. 1 further includes a display screen 111, and the display screen 111 is disposed on the front wall 110. The middle portion of the front sidewall 110 may be notched to allow the rear surface of the display 111 to be electrically connected to the above-mentioned electrical components, such as a processor.

In addition, the monitor 100 may also include a functional area 114. The functional area 114 may incorporate buttons (e.g., a power switch) for user operation and/or an indicator light to indicate whether the monitor 100 is powered on.

The alarm lamp is an alarm module widely applied to the monitor, and in the utility model, the alarm lamp is hidden in the cavity surrounded by the walls, and the specific arrangement mode is described in detail below.

In order to allow the optical warning signal of the warning lamp to be emitted from the cavity for easy observation by the user. The utility model is provided with an opening structure. Referring to fig. 1 and 2, the openings may include a first opening 112 and a second opening 122. The first opening 112 opens into one of the walls and the second opening 122 opens into another of the walls. This can facilitate the passage of an optical alarm signal through the first opening 112 and the second opening 122 for viewing. For example, the first opening 112 opens at the front sidewall 110. The first opening 112 is positioned such that the optical warning signal is visible to the user at most angles in the front direction. To further increase the visual range of the optical warning signal, the opening also comprises a second opening 122. Accordingly, the second opening is opened on another wall than the front sidewall 110, thereby providing a different viewing angle from the first opening 112. In this way, the optical warning signal can pass through the first opening 112 and the second opening 122 to be viewed. The arrangement of the plurality of openings enables the optical warning signal to thereby provide a larger viewing angle of the optical warning signal.

The position of the second opening may be arbitrary. In some embodiments, a second opening 122 may be opened in the rear sidewall 120 as shown in FIG. 2. Such an arrangement may ensure that the optical alarm signal is viewed by the user through the second opening 122 at most angles in the rear direction.

The optical alarm signal is generated by a light emitting component. The specific structure of the light emitting assembly 300 can be as shown in fig. 3. Fig. 3 illustrates a first view of the monitor 100 with the top wall removed in some embodiments of the utility model. The light emitting device 300 is disposed in the cavity, and includes a circuit board 301 and a plurality of light emitting elements 302 disposed on the circuit board 301. The light emitting elements 302 are capable of emitting an optical alarm signal for viewing through the first opening 112 and the second opening (e.g., the second opening 122 disposed in the rear sidewall) as described above. The light emitting elements 302 may be light emitting diodes. As shown in fig. 3, the number of the light emitting diodes may be multiple, and multiple light emitting diodes (light emitting elements 302) may be uniformly distributed on the circuit board 301 according to a certain rule, and the light emitting principle, the power supply mode, and the control mode may be any in the art, and are not described herein again.

As can be seen from fig. 1 to 3, the light emitting device 300 is hidden in the cavity inside the housing, so that the isolation between the light emitting device 300 and the external environment is improved, and the light emitting device 300 is prevented from being damaged. Furthermore, more importantly, because of the arrangement in the internal cavity of the housing, the light emitting assembly 300 can have a larger size and, accordingly, a wider viewing range than the prior art warning lamp embedded in the housing. Inlay the alarm lamp of establishing on the casing among the prior art because including the great component of size such as lamp plate, often need great opening, consequently can't select the longer alarm lamp in the size, avoid the too big reduction that leads to the firm degree of monitor casing of opening. The light emitting component is arranged in the cavity of the shell but not on the wall of the shell, and the size is not limited by the condition. As can be seen from fig. 1-3, the light assembly 300 of the present invention has a longer size and thus can emit a more striking optical warning signal. Because the opening only needs to enable the optical alarm signal to penetrate through, the area of the opening does not need to be too large, and even if the opening is long in length, the firmness of the whole monitor is not reduced. In addition, the light emitting assembly 300 of the present invention only includes a complete circuit board 301, and the visualization of the optical alarm signal at multiple angles can be realized through the plurality of openings, so that a plurality of light emitting assemblies are not required, which also reduces the device cost and the installation complexity.

The shape of the opening may be specially designed in order to allow as much of the optical warning signal emitted by the light assembly 300 to be transmitted outward as possible. For example, the first opening 112 and the second opening 122 may be configured as elongated openings in a direction substantially parallel to the circuit board 301. Such an arrangement ensures that the light emitted by the plurality of light-emitting elements 302 on the circuit board 301 can be observed as much as possible by the user, improving the intelligibility of the optical alarm signal. It should be noted that the shape of the opening of the elongated opening may be any shape, such as a straight line, a wavy line, or other easily recognizable shape. By substantially parallel is meant that the direction of the elongated opening is as parallel as possible to the plane of the circuit board and is allowed to deviate within a certain range, which will not be described in detail herein.

In the use process of the monitor, different situations needing alarming are usually faced. These situations are sometimes more urgent and may be reprocessed later. In addition, the same situation requiring an alarm may also face different degrees of severity. In some embodiments of the present invention, the monitor 100 may be configured to distinguish between the different situations described above. Referring to fig. 4, a second view of the monitor 100 is shown with the top wall removed in some embodiments of the utility model. As shown in this figure, the circuit board may include a first region 401 and a second region 402. The first region 401 and the second region 402 may be two portions of regions independent of each other. For example, as shown in fig. 4, the first region 401 is located on the left side of the circuit board and the second region 402 is located on the right side of the circuit board. The light emitting elements on the first area 401 emit an optical warning signal of a first color, for example blue. The light emitting elements on the second area 402 emit an optical warning signal of a second color, for example red. Thus, the electrical components in the monitor, such as the processor, can control the light emitting elements in the first area 401 to emit light in the face of some event that requires an alarm; the light emitting elements on the second area 402 are controlled to emit light in the face of other events requiring an alarm. Because the colors of the light emitted by the light-emitting elements on the first area and the second area are different, a user can easily judge the type of the alarm event according to the colors. In some embodiments, some of the above-mentioned events requiring an alarm may be relatively mild events, in which case an optical alarm signal of blue color may be emitted by the light-emitting elements on the first area 401; other events requiring an alarm may be relatively urgent events, where a red optical alarm signal may be emitted by the light emitting elements in the second area 402. In addition, when various events needing alarming occur, the light-emitting elements on the first area and the second area can be controlled to emit light simultaneously. In other embodiments, the types of alarm events corresponding to the light-emitting elements on the first and second areas emitting light can be set by the user. The user can configure the corresponding alarm type according to the use habit of the user.

The first and second regions may be partitioned by a partition 403 disposed at an upper portion of the circuit board, so that interference caused by light of different colors crossing each other in the first and second regions can be prevented. The partition 403 may be disposed in any manner, for example, it may be fixedly connected to the circuit board, or may be fixed in the cavity of the monitor, which is not described herein again. Accordingly, the openings on the walls of the monitor can be divided into a first portion and a second portion, the first portion corresponds to the first area 401, and the second portion corresponds to the second area 402. This ensures that the optical warning signal from the first zone 401 and the optical warning signal from the second zone 402 are more clearly distinguished when viewed from the outside by the user. For example, as shown in fig. 4, the first opening provided in the front side wall is partitioned into a first portion 411 provided as the first opening and a second portion 412 provided as the first opening; the second opening provided at the rear sidewall is partitioned into a first portion 421 provided as the second opening and a second portion 422 of the second opening. The manner of the partition arrangement may be various. For example, the partition plate 403 may be inserted into an opening to perform partitioning. The first part and the second part can be directly separated in the processing process. And will not be described in detail herein.

With continued reference to fig. 4, the present invention may further include a light sensor 404, wherein the light sensor 404 is disposed on the circuit board. Specifically, the light sensor 404 may be disposed at one end of the circuit board. This arrangement improves the integration of light sensor 404 with the light emitting assembly. The light sensor 404 may be used to sense the brightness of the external environment, and then send a signal to the processor inside the monitor to control the brightness of the display, so that the brightness of the display is easy for the user to observe. The specific structure of the light sensor 404 can be any one of the prior art, and will not be described herein.

In order to enable the light sensor 404 to receive the light from the external environment, a light inlet channel may be correspondingly provided. The light inlet channel is used to enable light from the external environment to irradiate the light sensor 404, and the position of the light inlet channel can be any. For example, referring back to fig. 1, it may be a light entrance channel 113 disposed at the front sidewall 110. The light inlet channel 113 corresponds to the light sensor 404. The light sensor 404 receives light from the environment through the light inlet channel 113. The sensed light intensity can be used for adjusting the brightness of the display.

The specific structure of the optical alarm device in some embodiments of the present invention is described in more detail below. Referring to fig. 5, a cross-sectional view of fig. 1 along line a-a is shown.

As shown in FIG. 5, the first opening 112 of the monitor opens at the front sidewall 110. In order to ensure the sealing performance of the first opening 112, a front light-transmitting layer 501 is further disposed on the front sidewall 110. As shown in fig. 5, the front transparent layer 501 covers both the display panel 111 and the first opening 112. In particular, the front light-transmitting layer 501 may be made of a single piece of light-transmitting material, for example, a glass panel or a transparent plastic. On the one hand, the front light-transmitting layer 501 serves as a protective cover for the display screen 111, and on the other hand, the front light-transmitting layer 501 completely covers the first opening 112, so as to prevent liquid, dust and the like from entering the monitor. Medical instruments are often sterilized during use. Existing monitor alarm lights are typically not planar with the monitor's outer surface contour, e.g., the alarm light may be raised or at least have a seam with the monitor's outer surface. The front light-transmitting layer 501 is arranged, so that the front outer surface of the whole monitor is seamless. Therefore, the disinfection efficiency of the monitor in the daily use process is greatly improved. On one hand, the disinfectant is not easy to enter the inside of the monitor, and on the other hand, the front surface of the monitor is not easy to stain due to no seam.

With continued reference to fig. 5, a second opening 122 opens into the rear sidewall 120. A second light transmitting layer 502 is also disposed on the rear sidewall 120. The second transparent layer 502 is made of a transparent material or a semitransparent material, such as a transparent plastic or a glass material. The second light transmitting layer 502 fills the second opening 122 and is substantially flush with the outer surface of the rear sidewall 120. The filling method may be any method, for example, as shown in fig. 5, the second transparent layer 502 includes a bent structure for hooking the inner surface of the rear sidewall 120. The flush arrangement ensures that the seams between the various components, such as the second opening 122, the rear sidewall 120, and the second light-transmitting layer 502 are tight, thereby improving the sealing of the instrument while facilitating the sterilization process by the user.

The second opening 122 may also be specially designed in order to further increase the visibility of the optical alarm signal. For example, as shown in fig. 5, the rear sidewall 120 may not be a planar structure, but may include a projection 520. The second opening 122 may be configured to open along the protrusion 520. Thus, the second opening 122 is positioned to protrude from the surrounding plane, and thus is more conspicuous. When the light emitting element emits light through the second light-transmitting layer 502 of the second opening 122, it will be more easily observed.

The inventors have found that the position of the light emitting element arranged on the circuit board 301 has a significant influence on the propagation angle of the optical warning signal. In order to further increase the visual range of the optical warning signal, in some embodiments, the position of the light emitting element may be specially designed. For example, as shown in fig. 5, the light emitting elements may be arranged in a regular pattern. It may comprise two rows of light emitting elements extending in the direction of the long sides of the circuit board 301, a first row of light emitting elements 311 and a second row of light emitting elements 312. Wherein the first row of light emitting elements 311 is arranged close to the first opening 112; a second row of light-emitting elements 312 is disposed proximate to the second opening 122. At the same time, the first row of light emitting elements 311 is configured to emit the optical alarm signal generally towards the second opening 122, and the second row of light emitting elements 312 is configured to emit the optical alarm signal generally towards said first opening 112. The direction of the optical alarm signal emitted by the first and second rows of light-emitting elements can be controlled by the orientation of the light-emitting element bases, for example, the first row 311 of light-emitting elements bases is arranged to face the second opening 122, and the second row 312 of light-emitting elements bases is arranged to face the first opening 112.

This arrangement ensures that the optical warning signal emitted by the light-emitting element is observed over a larger angular range after passing through the first and second openings. The reason may be that the above-described configuration of the present invention can ensure that the light of the light emitting elements is emitted from the openings after being diverged by a certain distance (e.g., the distance between the first row of light emitting elements 311 and the second opening 122), compared to the manner in which the light emitting elements directly emit light outward close to their corresponding openings, which can make the angle of scattering of the optical alarm signal larger, and thus the optical alarm signal is more conspicuous.

In order to improve the efficiency of the light emitting element for emitting the optical alarm signal to the outside of the monitor, some embodiments of the present invention further provide a light guide. The light guide member may be disposed at least partially between the light emitting element and the opening, so as to guide the optical alarm signal emitted by the light emitting element to be emitted outside the monitor as much as possible for observation by the user. For example, as shown in fig. 5, the light guide may include a first light guide portion 503 disposed between the light emitting element and the first opening 112, and a second light guide portion 504 disposed between the light emitting element and the second opening 122. The first light guide part 503 and the second light guide part 504 may be fixedly connected at the bottom as shown in fig. 5, i.e. integrally formed, or may be separately disposed. The material of the light guide member may be a conventional light guide material in the art, such as polymethyl methacrylate (PMMA), Polycarbonate (PC), etc., and will not be described herein again. The integrally formed light guide may at least partially surround the circuit board 301, providing support and protection for the circuit board. The integrally formed light guide piece can also greatly reduce the difficulty of assembling each part and is easy to align between the light emitting element and the light guide piece.

The patentable scope of the utility model is defined by the claims, and may include other examples that occur to those skilled in the art.
