Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to a patient monitor and its functional module assembly structure. Background Technology
[0002] Patient monitors are widely used medical devices in clinical practice, used to monitor patients' vital signs and physiological parameters in real time, providing crucial information for medical diagnosis and treatment planning.
[0003] Existing monitors include a main body and functional modules. The main body comprises a rear shell and a front shell, with a cavity formed inside the rear shell. The front shell is fitted onto the rear shell and covers the opening of the cavity. The functional modules are assembled within the cavity of the rear shell. The functional modules adopt an integrated circuit board structure, integrating core functional units such as parameter processing units, main control units, and power management units. The functional modules are positioned close to the front shell and are roughly parallel to its surface. While this design effectively reduces the space required for the cavity, thus achieving miniaturization of the main body, it has the following drawbacks in practical applications: First, poor heat dissipation of the power management unit can easily lead to unstable voltage and abnormal operation, shorten the lifespan of hardware (such as accelerating the aging of components such as capacitors and resistors), and increase safety hazards (such as high temperature may cause the circuit board solder joints to desolder and the insulation layer to age, posing a potential risk of short circuit and electric shock). Secondly, it is not conducive to the reasonable design of various interfaces. Because the monitor needs to be equipped with multiple interfaces such as power interface, data transmission interface, and sensor connection interface to meet the usage requirements, the layout of the integrated functional module and the installation structure close to the front shell impose strong restrictions on the installation position and orientation of the interfaces, which makes it inconvenient to connect the monitor with various external measuring devices (such as electrode pads, pulse oxygen probes, blood pressure cuffs, body temperature probes, etc.). Third, the parameter processing unit and the main control unit are easily affected by radiation interference due to their close proximity, which can cause distortion of the original physiological signals and ultimately affect the measurement accuracy. Utility Model Content
[0004] To address the aforementioned issues, the primary objective of this invention is to provide a functional module assembly structure that improves heat dissipation and interface layout while reducing electromagnetic interference.
[0005] The second objective of this invention is to provide a monitor with the above-mentioned functional module assembly structure.
[0006] To achieve the first objective of this utility model, it provides a functional module assembly structure, comprising a main control board, a parameter processing board, and a power management board. The first body of the main control board has a first clearance position. The parameter processing board is electrically connected to the main control board. In the normal direction of the main control board, the projection of the second body of the parameter processing board lies within the projection of the first clearance position. The second body and the first body have a first projection distance in the normal direction, a second projection distance in a first direction, and a third projection distance in a second direction. The normal direction, the first direction, and the second direction are mutually perpendicular. The power management board is electrically connected to the main control board. In the normal direction, the projection of the third body of the power management board does not overlap with the projection of the second body, but overlaps with the projection of the first body. The third body and the first body have a fourth projection distance in the normal direction.
[0007] As can be seen from the above, by splitting the functional module into multiple independent functional boards, each functional board can perform its set functions. Furthermore, the structural and positional design of the functional boards ensures that the parameter processing board is protected from radiation interference from the main control board when acquiring various parameter signals, preventing distortion of the acquired raw physiological signals and guaranteeing measurement accuracy. This allows medical personnel to make more accurate diagnoses and formulate more precise treatment plans. In addition, it ensures effective heat dissipation for the components on the power management board, guaranteeing the normal and stable operation of the functional modules and helping to extend their lifespan. Moreover, it facilitates flexible design of the interface positions on the main control board and parameter processing board, improving the ease of connection and disconnection between the interfaces and external measuring devices.
[0008] A further option is that the functional module assembly structure also includes a heat sink, the mounting plate of the heat sink is provided with a second clearance position, the first plate is mounted on the mounting plate, and the first clearance position and the parameter processing plate are both located at the second clearance position; the mounting plate, the first plate, the second plate and the third plate of the heat sink are distributed in sequence in the normal direction.
[0009] As can be seen from the above, the heat sink provides reliable support for the main control board, ensuring its structural and connection strength. On the other hand, it also helps the main control board dissipate heat, ensuring its stability and reliability.
[0010] A further proposed solution is that the first projection distance is greater than or equal to 2 mm; the second projection distance is greater than or equal to 6 mm; the third projection distance is greater than or equal to 2 mm; and the fourth projection distance is greater than or equal to 12 mm.
[0011] As can be seen from the above, by designing the first to the third projection distance, the main control board can be effectively prevented from affecting the acquisition of the original physiological signals of the parameter processing board, thus avoiding distortion of the original physiological signals acquired by the parameter processing board. Furthermore, by designing the fourth projection distance, the circuit management board can be effectively cooled, while also preventing the heat emitted by the circuit management board from affecting the main control board and the parameter processing board.
[0012] A further proposed solution is that the first plate and the mounting plate have a fifth projection distance in the normal direction, the fifth projection distance being greater than or equal to 6 mm; and / or the second plate and the mounting plate have a sixth projection distance in the normal direction, the sixth projection distance being greater than or equal to 10 mm.
[0013] As can be seen from the above, the design of the fifth projection distance can ensure that the main control board is effectively cooled, thus guaranteeing its stability and reliability. Since the heat sink is generally made of metal, the design of the sixth projection distance can also prevent the metal plate from affecting the original physiological signal of the parameter processing board, thus ensuring measurement accuracy.
[0014] A further proposed solution is that the main control board is equipped with a first interface group, and the parameter processing board is equipped with a second interface group, with the first interface group and the second interface group located on different sides of the functional module assembly structure.
[0015] As can be seen from the above, by designing the relative positions of the first interface group and the second interface group, the first interface group and the second interface group can contain more different types of interfaces, and the interface position design is more flexible and more reliable.
[0016] A further proposed solution is that the first interface group includes at least one of the following: an HDMI interface, a USB interface, a network interface, and a DC power socket.
[0017] As can be seen from the above, by setting up the various interfaces mentioned above, the functional module enables the monitor equipped with the functional module to meet different usage requirements such as video output, data transmission, and power supply.
[0018] A further proposed solution is that the second interface group includes at least one of the following: ECG interface, TEMP interface, SpO2 interface, NIBP interface, IBP interface, CO2 interface, and extended interface.
[0019] As can be seen from the above, by setting up the various interfaces mentioned above, the functional module enables the monitor equipped with the functional module to collect various physiological parameters, assisting medical staff in making accurate medical diagnoses and formulating treatment plans.
[0020] To achieve the second objective of this utility model, this utility model provides a monitor, including a body, which includes a rear shell and a front shell. The rear shell has a receiving cavity, and the front shell is mounted on the rear shell and covers the opening of the receiving cavity. The monitor also includes the aforementioned functional module assembly structure, which is disposed within the receiving cavity.
[0021] As can be seen from the above, by setting up the above-mentioned functional module assembly structure, the patient monitor can monitor various physiological parameters and provide early warning of abnormal conditions more accurately and reliably, providing more accurate data support for clinical diagnosis, treatment and nursing; at the same time, it also helps to extend the service life of the patient monitor.
[0022] A further design involves the first, second, and third plates being parallel to each other, and all three plates being perpendicular to the front shell; the rear shell is provided with multiple sets of heat dissipation holes, which are connected to the receiving cavity.
[0023] As can be seen from the above, this design can ensure the heat dissipation of the main control board, parameter processing board and power management board, and make the overall assembly structure of the functional modules more compact, reducing the space required and contributing to the miniaturization design of the monitor.
[0024] A further improvement is that the monitor also includes a display screen and an operation module, both of which are mounted on the front cover and electrically connected to the main control board.
[0025] As can be seen from the above, the design of the display screen and operation module helps medical staff to quickly browse and view the various physiological parameters and historical parameter data collected by the function modules, and also allows the monitor to re-detect the patient's various physiological parameters.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0035] Patient monitor examples Reference Figures 1 to 3 The monitor 100 includes a body 1, a display screen 2, an operation module 3, and a functional module assembly structure 4.
[0036] The main body 1 includes a front shell 11 and a rear shell 12. The rear shell 12 has a receiving cavity 121 for accommodating the functional module assembly structure 4. The front shell 11 is mounted on the rear shell 12 and covers the opening of the receiving cavity 121. The display screen 2 is mounted on the front shell 11 and can be used to display various physiological parameter data collected by the functional module assembly structure 4, so that medical staff can quickly and intuitively understand the patient's various physiological parameters. The operation module 3 is mounted on the front shell 11 and is used to cooperate with the display screen 2 so that medical staff can quickly browse and view the various physiological parameters and historical parameter data collected by the functional module through the operation module 3. At the same time, it can also control the various measuring devices connected to the monitoring (such as electrode pads, temperature probes, blood oxygen sensors, inflatable blood pressure cuffs, airway sensors, etc.) to re-detect the patient's various physiological parameters.
[0037] Combination Figure 4 The functional module assembly structure 4 includes a main control board 41, a parameter processing board 42, a power management board 43, and a heat sink 44. The main control board 41 is electrically connected to the parameter processing board 42, the power management board 43, the display screen 2, and the operation module 3, enabling it to process the parameters collected by the parameter processing board 42 and display them on the display screen 2. Furthermore, the main control board 41 can receive control commands from the operation module 3 and execute related operations (such as browsing and reviewing various physiological parameters and historical parameter data, or controlling related measuring devices to re-collect the patient's corresponding physiological parameters). Moreover, the main control board 41 also receives electrical energy output from the power management board 43 and supplies power to related devices, ensuring that each device operates under a safe and stable power supply voltage.
[0038] Combination Figures 5 to 7The main control board 41 includes a first board body 411 and a first interface assembly 412, which is mounted on the first board body 411. A first clearance position 4111 is provided on the first board body 411, which penetrates the first board body 411 along its normal Z direction (i.e., the normal Z direction of the main control board 41). The first interface assembly 412 includes at least one of an HDMI interface 4121, a USB interface 4122, a network interface 4123, and a DC power socket 4124. In this embodiment, the first interface assembly 412 includes one of these three interfaces.
[0039] The HDMI interface 4121 can be connected to devices such as monitors and projectors to display parameter waveforms, numerical reports and other content on the display screen 2 in high-definition quality, adapting to scenarios such as multi-screen monitoring and remote consultation.
[0040] The USB interface 4122 enables data transfer and expands connectivity with external devices. For example, medical staff can connect storage devices such as USB flash drives and external hard drives via the USB interface 4122 to export monitoring data for archiving or analysis. It can also be connected to a printer to directly print monitoring records. The network interface 4123 (such as an RJ45 interface) is used to realize network connection and data network transmission, so that the monitor 100 can be connected to the hospital's local area network, realize data synchronization with the central monitoring system and electronic medical record system, and facilitate medical staff to remotely view the monitoring data of multiple patients at the nurse station.
[0041] DC power socket 4124 enables the monitor 100 to supply power to external devices and / or to a certain module within the monitor 100, thereby enhancing the functionality of the monitor 100.
[0042] Along the normal Z direction, the parameter processing board 42 is located on one side of the main control board 41. The parameter processing board 42 includes a second board body 421 and a second interface group 422. The second interface group 422 is connected to the first board body 411 to transmit the parameter signals received by the second interface group 422 to the first board body 411 for preliminary processing, and finally to the main control board 41 for final processing.
[0043] In the normal direction Z, the projection of the second plate 421 lies within the projection of the first clearance position 4111, and the second plate 421 and the first plate 411 have a first projection distance L1 in the normal direction Z; furthermore, the second plate 421 and the first plate 411 have a second projection distance L2 in the first direction X, and a third projection distance L3 in the second direction Y. The normal direction Z, the first direction X, and the second direction Y are all perpendicular to each other. This design provides a certain safety gap between the parameter processing board 42 and the main control board 41 to avoid interference from radiation from the main control board 41 when the parameter processing board 42 collects various parameter signals, thereby preventing distortion of the collected raw physiological signals, ensuring measurement accuracy, and ensuring that medical personnel can make correct diagnoses and formulate precise treatment plans.
[0044] Preferably, the first plate 411 and the second plate 421 are substantially parallel, and the first plate 411 and the second plate 421 are substantially perpendicular to the front shell 11 (i.e., perpendicular to the display screen 2), making the functional module assembly structure 4 more compact overall, reducing the space it occupies, and contributing to the miniaturization design of the monitor 100. Furthermore, the first projection distance L1 is preferably greater than or equal to 2 mm; the second projection distance L2 is preferably greater than or equal to 6 mm; and the third projection distance L3 is preferably greater than or equal to 2 mm. By designing the first projection distance L1, the second projection distance L2, and the third projection distance L3, it can be ensured that the main control board 41 does not affect the acquisition of the original physiological signals by the parameter processing board 42, avoiding distortion of the original physiological signals acquired by the parameter processing board 42; at the same time, it also helps to arrange the functional module assembly structure 4 within a reasonable space, thereby reducing the space occupied by the functional module assembly structure 4.
[0045] The first interface group 412 and the second interface group 422 are preferably located on different sides of the functional module assembly structure 4. In this embodiment, the first interface group 412 is preferably located on the opposite side of the display screen 2 (i.e., the back side of the rear shell 12). Since the devices connected to the first interface group 412 are not frequently plugged in or unplugged, and the back side of the rear shell 12 may be close to a wall or in a difficult-to-operate location when the monitor 100 is in use, placing the first interface group 412 on the back side of the rear shell 12 ensures it does not obstruct the plugging and unplugging connection between the second interface group 422 and the relevant measuring devices. The second interface group 422 is preferably located close to the adjacent side of the display screen 2, making it easier to add, remove, replace, and assemble / disassemble the measuring devices with the second interface group 422. Thus, through the relative positional design of the first interface group 412 and the second interface group 422, on the one hand, the first interface group 412 and the second interface group 422 can contain more different types of interfaces; on the other hand, it improves the flexibility of interface position settings and enhances interface reliability, while also facilitating the disassembly, assembly, and replacement of measuring devices by medical personnel.
[0046] The second interface group 422 includes at least one of the following: ECG interface, TEMP interface, SpO2 interface, NIBP interface, IBP interface, CO2 interface, and expansion interface. By setting the above-mentioned interfaces, the functional module enables the monitor 100 equipped with the functional module to collect various physiological parameters, assisting medical staff in making accurate medical diagnoses and formulating treatment plans.
[0047] The ECG interface is used to connect to the electrode pads. The electrode pads are attached to the patient's chest, limbs and other parts to collect the weak electrical activity signals generated when the heart beats. The signals are then transmitted to the parameter processing board 42 and the main control board 41 to be converted into standard electrocardiogram waveforms. At the same time, the heart rate is calculated to help determine cardiac abnormalities such as arrhythmia.
[0048] The TEMP interface is used to connect surface or internal temperature probes to collect patients' body temperature data. Since body temperature signals are low-precision analog signals, the signals transmitted by this interface can be converted into intuitive temperature values and directly displayed on the monitor after simple processing, so that medical staff can quickly determine whether the patient has a fever or hypothermia.
[0049] The SpO2 interface is used to connect to finger clip, earlobe, and other blood oxygenation sensors. It can detect the proportion of oxyhemoglobin in the blood through the red and infrared light emitted by the sensor, and can also collect pulse rate signals simultaneously. After processing, the light signals transmitted by the interface can output the percentage of blood oxygen saturation and pulse rate values, which can be directly displayed on the monitor for medical staff to assess the body's oxygenation function.
[0050] The NIBP interface is used to connect an inflatable blood pressure cuff. During the inflation and deflation process of the cuff, the oscillation wave signal of the arterial blood vessels is collected. After the signal is transmitted to the parameter processing board 42 and the main control board 41, the systolic blood pressure, diastolic blood pressure and mean arterial pressure are calculated by the algorithm and directly displayed on the monitor for medical staff to view and diagnose.
[0051] The IBP interface is used to connect to pressure catheters implanted in patients' arteries, central veins, and other blood vessels. It can directly collect real-time pressure signals from within the blood vessels. The transmitted signals are highly accurate and can present continuous blood pressure waveforms directly on the monitor. It can be used in scenarios that require precise blood pressure monitoring and can provide timely feedback on instantaneous fluctuations in blood pressure.
[0052] The CO2 interface is used to connect airway sensors to collect carbon dioxide concentration signals in the patient's exhaled air, especially focusing on the concentration peak at the end of expiration. After the transmitted signal is processed, it generates a carbon dioxide concentration value and a characteristic square wave, which are directly displayed on the monitor. This allows medical staff to confirm whether the endotracheal tube is in the correct position and to assess the patient's lung ventilation and metabolic status.
[0053] The expansion interface can be used to connect other measurement devices and expansion function boards to enable more physiological parameter detection functions.
[0054] In the Z-direction, the projection of the third plate 431 of the power management board 43 does not overlap with the projection of the second plate 421, but the projection of the third plate 431 overlaps with the projection of the first plate 411. Furthermore, the power management board 43 and the parameter processing board 42 are preferably distributed along the first direction X. The third plate 431 and the first plate 411 have a fourth projection distance L4 in the Z-direction to ensure effective heat dissipation of the components on the power management board 43, ensuring the normal and stable operation of the functional modules and helping to extend their service life. Preferably, the fourth projection distance L4 is greater than or equal to 12 mm, allowing the circuit management board to achieve effective heat dissipation while also preventing the heat dissipated by the circuit management board from affecting the main control board 41 and the parameter processing board 42. Moreover, the third plate 431 is substantially parallel to the first plate 411 and is also perpendicular to the front shell 11.
[0055] Combination Figure 8 The mounting plate 441 of the heat sink 44 is provided with a second clearance position 4411, which penetrates the mounting plate 411 in the normal direction Z. The first plate 411 is mounted on the mounting plate 411, and both the first clearance position 4111 and the parameter processing plate 42 are located at the second clearance position 4411. The mounting plate 441, the first plate 411, the second plate 421, and the third plate 431 are distributed sequentially in the normal direction Z. The heat sink 44 is preferably made of a metal material (such as aluminum alloy or iron), so that it can reliably support the main control board 41, ensuring the structural and connection strength of the main control board 41, and also assist the main control board 41 in heat dissipation, ensuring the stability and reliability of the main control board 41's operation.
[0056] Furthermore, the first plate 411 and the mounting plate 441 have a fifth projection distance L5 in the normal Z direction, which is preferably greater than or equal to 6 mm. This design ensures effective heat dissipation for the main control board 41, guaranteeing its operational stability and reliability. Moreover, the second plate 421 and the mounting plate 441 have a sixth projection distance L6 in the normal Z direction, which is preferably greater than or equal to 10 mm. This avoids the metal heat sink 44 affecting the original physiological signals of the parameter processing board 42, ensuring measurement accuracy.
[0057] Furthermore, the rear housing 12 is provided with multiple sets of heat dissipation holes 122, which communicate with the receiving cavity 121, and the multiple sets of heat dissipation holes 122 are distributed on different parts of the rear housing 12. The arrangement of the heat dissipation holes 122 can enhance the air convection inside and outside the receiving cavity 121, improve the heat dissipation effect on the main control board 41, parameter processing board 42, and power management board 43, so as to ensure the reliability and stability of the monitor 100 and help extend the service life of the monitor 100.
[0058] In summary, by splitting the functional module into multiple independent functional boards, each functional board can perform its set functions, and the heat dissipation of the functional module can be improved. This avoids interference from the main control board 41 when the parameter processing board 42 collects various parameter signals, prevents distortion of the collected raw physiological signals, and ensures measurement accuracy. Through the design of this functional module assembly structure 4, the monitor 100 can monitor various physiological parameters of patients and provide early warning of abnormal conditions more accurately and reliably, providing more accurate data support for clinical diagnosis, treatment, and nursing. At the same time, it also helps to extend the service life of the monitor 100.
[0059] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
