Description

Technical Field

[0001] This invention relates to the field of hemorrhagic shock monitoring, and more particularly to a microcirculation monitoring device and system for hemorrhagic shock. Background Technology

[0002] Traumatic hemorrhagic shock is a type of hypovolemic shock caused by severe trauma, and it is one of the main causes of death among the wounded at disaster sites, accident sites, battlefields, and during transport and evacuation. Traumatic blood loss includes acute massive hemorrhage and occult hemorrhage. Compared with acute massive hemorrhage, occult hemorrhage is not easy to observe, and therefore often endangers the life of the wounded due to delayed detection.

[0003] Early signs of hemorrhagic shock include microcirculatory dysfunction and insufficient peripheral microcirculatory perfusion, which is one of the most easily identifiable clinical manifestations. Therefore, diagnosis can be made based on capillary refill time (CRT). CRT refers to the time required for the distal capillary bed to regain its original color (i.e., refill) after being compressed. When peripheral microcirculatory dysfunction is present, CRT will be significantly prolonged. Therefore, monitoring the patient's CRT can help identify hemorrhagic shock early.

[0004] The traditional CRT monitoring method involves a clinician applying pressure to the patient's nail bed for several seconds, then visually observing the time it takes for the nail bed to regain its redness, and making a diagnosis based on this recovery time. This method is limited by human factors (such as the location and pressure applied to the capillary bed, and observer bias), which can lead to diagnostic errors.

[0005] Currently, there are also CRT devices that monitor the wounded by incorporating pressurization modules. These modules primarily come in three types: servo motors with mechanical transmission, air pumps, and motors with mechanical transmission. However, all three solutions are structurally complex and inconvenient to use in complex environments such as disasters, accidents, and battlefields. Furthermore, when the pressurization module in current monitoring devices releases pressure, its complex transmission structure prevents the instantaneous release of pressure applied to the fingers. This can affect the refilling of the fingers and thus interfere with CRT measurement results.

[0006] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0007] The main objective of this invention is to provide a microcirculation monitoring device and system for hemorrhagic shock, aiming to solve the problems of complex structure and low detection accuracy of mechanical transmission pressurization modules in existing monitoring devices.

[0008] To achieve the above objectives, the present invention provides a microcirculation monitoring device for hemorrhagic shock, comprising:

[0019] In this embodiment of the application, the spring-opening component is a first spring assembly, which is disposed between the upper finger clip and the lower finger clip. The upper and lower ends of the first spring assembly are respectively connected to the upper finger clip and the lower finger clip, and the first spring assembly is in a compressed state when the upper finger clip and the lower finger clip are clamped.

[0020] In this embodiment of the application, the first spring assembly includes two first springs, which are respectively sleeved on the two connecting posts.

[0021] In this embodiment of the application, a first bellows is sleeved on the outer side of each of the two first springs.

[0022] In this embodiment of the application, the monitoring device further includes a first cover, one end of which is hinged to the lower finger clip, and the other end of which is open to the lower finger clip.

[0024] In this embodiment of the application, the monitoring device further includes a second cover, one end of which is fixedly connected to the lower finger clip, and the other end of which is open to the lower finger clip. The upper finger clip and the electromagnetic pressure assembly are both located at the opening between the second cover and the lower finger clip.

[0025] The spring-opening assembly includes multiple second springs, with both ends of the multiple second springs connected to the upper surface of the upper finger clip and the second cover, respectively. When the upper finger clip and the lower finger clip are in the clamping state, the multiple second springs are all in the stretched state.

[0026] In this embodiment of the application, a second bellows is sleeved on the outer side of each of the plurality of second springs.

[0027] This application also proposes a microcirculation monitoring system for hemorrhagic shock, comprising the microcirculation monitoring device for hemorrhagic shock described in any of the above claims, wherein the monitoring system further comprises:

[0051] like Figure 1As shown, this exemplary embodiment proposes a microcirculation monitoring device 100 for hemorrhagic shock, comprising:

[0052] An upper finger clip 110 and a lower finger clip 120 are arranged opposite to each other. The lower surface of the upper finger clip 110 is provided with a first clamping area 111, and the first clamping area 111 is provided with a first signal transceiver device 112. The upper surface of the lower finger clip 120 is provided with a second clamping area 121 that matches the first clamping area 112, and the second clamping area 121 is provided with a second signal transceiver device 122. A pressure sensor 170 is provided on the first clamping area 111 and / or the second clamping area 121. The first signal transceiver device 112 and the second signal transceiver device 122 are used to monitor the refill time of the finger capillaries, and the pressure sensor 170 is used to monitor the clamping force of the upper finger clip 110 and the lower finger clip 120.

[0053] The electromagnetic pressure assembly 160 is connected to the upper finger clip 110 and the lower finger clip 120 respectively. The electromagnetic pressure assembly 160 is used to clamp the upper finger clip 110 and the lower finger clip 120 by attraction or repulsion.

[0054] A pop-up assembly for popping the upper finger clip 110 and the lower finger clip 120 apart.

[0055] like Figure 1 As shown, the upper finger clip 110 and the lower finger clip 120 are configured with an opening. One end of the opening can clamp the finger of the person being monitored between the upper finger clip 110 and the lower finger clip 120. When the upper finger clip 110 and the lower finger clip 120 clamp inward, one end of the opening comes closer to each other and clamps the finger of the person being monitored in the middle.

[0056] like Figure 2 As shown, Figure 2 The image shows a cross-sectional view of the opening end of the upper finger clip 110 and the lower finger clip 120. The first clamping area 111 on the lower surface of the upper finger clip 110 and the second clamping area 121 on the upper surface of the lower finger clip 120 are both roughly curved surfaces. The clamping areas of the two curved surfaces are roughly contoured to the outer contour of the fingers, thus making it convenient to insert and clamp the fingers.

[0057] Continue to refer to Figure 2 A first signal transceiver 112 and a second signal transceiver 122 are respectively provided on the first clamping area 111 and the second clamping area 121. For example, a signal transmitter is provided on the first clamping area 111 and a signal receiver is provided on the second clamping area 121; or, a signal receiver is provided on the first clamping area 111 and a signal transmitter is provided on the second clamping area 121. The signal transceiver can be an infrared transmitter and an infrared receiver. The infrared transmitter can emit infrared rays, which can be received by the infrared receiver after passing through the finger.

[0058] Continue to refer to Figure 2 The first clamping area 111 or the second clamping area 121 is also equipped with a pressure sensor 170. When the upper finger clip 110 and the lower finger clip 120 clamp together, the pressure sensor 170 can detect the amount of pressure applied to the finger by the upper finger clip 110 and the lower finger clip 120. The pressure sensor 170 can be a thin-film pressure sensor 170. Using a thin-film pressure sensor 170 facilitates installation in the first clamping area 111 or the second clamping area 121. Moreover, after the thin-film pressure sensor 170 is attached to the first clamping area 111 or the second clamping area 121, it can fit tightly to the shape of the finger, and will not interfere with the detection when pressure is applied.

[0059] Continue to refer to Figure 2 In this embodiment, the lower finger clip 120 has a first mounting cavity 123 inside. The electromagnetic pressure assembly 160 includes a first magnet 161, a second magnet 162, and a connecting post 130. The first magnet 161 and the second magnet 162 are both located in the first mounting cavity 123. The upper wall of the lower finger clip 120 has a first through hole 126 that communicates with the first mounting cavity 123. The first through hole 126 is used for the connecting post 130 to pass through, so that one end of the connecting post 130 is located in the first mounting cavity 123 and connected to the first magnet 161, and the other end is located outside the first mounting cavity 123 and connected to the upper finger clip 110.

[0060] In this embodiment, the electromagnetic pressure assembly 160 can control the first magnet 161 and the second magnet 162 to generate attractive or repulsive forces, thereby clamping the upper finger clip 110 and the lower finger clip 120. The specific attractive and repulsive force methods are as follows:

[0061] Suction method: such as Figure 3 As shown, the first magnet 161 is a permanent magnet, and the second magnet 162 is an electromagnet. The second magnet 162 is located below the first magnet 161 and is fixedly connected to the lower finger clip 120. When the second magnet 162 is energized, it generates a magnetism opposite to that of the first magnet 161, so the first magnet 161 and the second magnet 162 attract each other. The first magnet 161 drives the upper finger clip 110 downward through the connecting post 130, and the second magnet 162 drives the lower finger clip 120 upward, so that the upper finger clip 110 and the lower finger clip 120 move closer to the middle and clamp together.

[0062] Repulsive force methods: such as Figure 2As shown, the first magnet 161 is a permanent magnet, and the second magnet 162 is an electromagnet. The second magnet 162 is located above the first magnet 161 and is fixedly connected to the lower finger clip 120. When the second magnet 162 is energized, it generates the same magnetism as the first magnet 161, so the first magnet 161 and the second magnet 162 repel each other. The first magnet 161 drives the upper finger clip 110 downward through the connecting post 130, and the second magnet 162 drives the lower finger clip 120 upward, so that the upper finger clip 110 and the lower finger clip 120 move closer to the middle and clamp together.

[0063] Both the attraction and repulsion methods described above can control the clamping force between the upper finger clamp 110 and the lower finger clamp 120 by controlling the magnitude of the magnetic force generated by the second magnet 162.

[0064] In addition, one or more connecting posts 130 and first through holes 126 can be provided, for example... Figure 2 , Figure 3 As shown, two first through holes 126 and two connecting posts 130 can be respectively provided. The two first through holes 126 are located on both sides of the second clamping area 121. The two connecting posts 130 pass through the two first through holes 126 respectively. Thus, one end of the two connecting posts 130 is located outside the first mounting cavity 123 and connected to the upper finger clip 110, and the other end is located inside the first mounting cavity 123 and connected to the first magnet 161. The two connecting posts 130 apply force to the upper finger clip 110 from both sides of the first clamping area 111 and the second clamping area 121, so that the upper finger clip 110 is subjected to relatively uniform force.

[0065] Reference Figure 2 and Figure 3 In this embodiment of the application, the pop-out component is used to pop out the upper finger clip 110 and the lower finger clip 120.

[0066] For example, the spring-opening component is a first spring group, which is located between the upper finger clip 110 and the lower finger clip 120. The upper and lower ends of the first spring group are connected to the upper finger clip 110 and the lower finger clip 120 respectively. When the upper finger clip 110 and the lower finger clip 120 are clamped, the first spring group is in a compressed state. Thus, when the upper finger clip 110 and the lower finger clip 120 lose driving force, the first spring group can quickly spring the upper finger clip 110 and the lower finger clip 120 open.

[0067] Specifically, such as Figure 2 , Figure 3As shown in this embodiment, the first spring assembly includes two first springs 140, which are respectively sleeved on the two connecting posts 130. When the second magnet 162 is energized, regardless of whether the first magnet 161 and the second magnet 162 clamp the upper finger clip 110 and the lower finger clip 120 by attraction or repulsion, the two first springs 140 located on both sides of the first clamping area 111 and the second clamping area 121 are compressed. When the second magnet 162 is de-energized, the attraction or repulsion between the first magnet 161 and the second magnet 162 disappears instantly, and the two first springs 140 quickly rebound, causing the upper finger clip 110 and the lower finger clip 120 to spring open.

[0068] In this application, by controlling the magnitude of the current within the coil wound around the second magnet 162, the magnitude of the magnetic force generated by the second magnet 162 can be changed, thereby obtaining different clamping forces. The pressure sensor 170 can detect the clamping forces generated by the upper finger clamp 110 and the lower finger clamp 120. Therefore, different clamping forces can be preset and selected during use. Furthermore, the pressure sensor 170 can continuously monitor the clamping force between the upper finger clamp 110 and the lower finger clamp 120. When the detected clamping force is too large or too small, the magnitude of the current within the coil wound around the second magnet 162 can be increased or decreased to achieve a suitable clamping force. Compared to current manual finger pressure, this method is more controllable and standardized, avoiding errors caused by human factors.

[0069] When the upper finger clip 110 and lower finger clip 120 reach the appropriate clamping force, the infrared emitter emits infrared rays, which are received by the infrared receiver. At this time, due to the pressure applied to the finger, the capillaries in the finger are squeezed. There is no blood in the capillaries in the area of ​​the finger that is squeezed, and the color changes. If the same clamping force is continuously applied, the color of the finger remains unchanged. Assuming that the signal received by the infrared receiver at this time is the first signal, when the battery in the coil wound with the second magnet 162 is disconnected, the second magnet 162 instantly loses its magnetism. The pop-out component can quickly pop the upper finger clip 110 and lower finger clip 120 away. During the pop-out process, the pressure applied to the finger by the upper finger clip 110 and lower finger clip 120 gradually decreases to zero, and the blood in the capillaries of the finger is refilled, and the color gradually returns. Finally, after the refilling is completed, the color of the finger no longer changes. During this retraction process, the color of the finger changes continuously as it refills, and the signal received by the infrared receiver also changes continuously. When the finger refills, the signal received by the infrared receiver tends to stabilize. Assuming that the stabilized signal is the second signal, the time interval between the first signal and the second signal is the time for the capillaries in the finger to refill. By monitoring this interval, it is possible to determine whether the person being monitored is in hemorrhagic shock.

[0070] In this embodiment, the electromagnetic pressure component 160 and pressure sensor 170 can precisely control the magnitude of the clamping force applied to the finger, ensuring accuracy and controllability. The release component can quickly release the upper finger clamp 110 and lower finger clamp 120, allowing the finger to immediately refill, avoiding detection errors caused by slow release. The signal receiving and transmitting devices can also accurately detect the finger refill time. Compared to conventional finger pressing and visual estimation of refill time, this application is more controllable, more precise, and more standardized, and is not affected by human factors, resulting in more accurate detection results. Furthermore, since this application uses the electromagnetic pressure component 160, no other mechanical components are needed, making it lightweight and portable. The electromagnetic pressure component 160 is also more suitable for harsh environments such as disasters, accidents, and battlefields compared to mechanical pressure components.

[0071] like Figure 2 As shown, in this embodiment of the application, under the repulsive force mode, the inner top wall of the lower finger clip 120 is provided with a first accommodating cavity 124, and the second magnet 162 is disposed in the first accommodating cavity 124; as Figure 3 As shown, in the suction mode, the inner bottom wall of the lower finger clip 120 is provided with a second receiving cavity 125, and the second magnet 162 is located in the second receiving cavity 125. That is, regardless of whether the suction mode or the repulsion mode is used, the second magnet 162 is located in the receiving cavity inside the wall of the lower finger clip 120. The second magnet 162 is an electromagnet, and the coil wound around it is also located in the first receiving cavity 124 or the second receiving cavity 125, and the wire runs from the inside of the wall of the lower finger clip 120, so that it can be waterproof and dustproof, and can be used normally in harsh environments such as disaster accident sites, battlefields or the process of transferring and evacuating the wounded, thus having a wider range of applications.

[0072] like Figure 2 , Figure 3 As shown in the embodiment of this application, a first corrugated tube 150 can also be sleeved on the outside of the first spring 140, so that the first spring 140 and the connecting post 130 are isolated inside by the first corrugated tube 150, which has a better waterproof and dustproof effect, and can also prevent the first spring 140 from pinching the hand.

[0073] like Figure 4 , Figure 5 As shown in the embodiment of this application, the monitoring device 100 further includes a first cover 180. One end of the first cover 180 is hinged to the lower finger clip 120, and the other end is open to the lower finger clip 120. The upper finger clip 110, the electromagnetic pressure component 160, and the spring-opening component are all located at the opening position of the first cover 180 and the lower finger clip 120.

[0074] in, Figure 4 To use a repulsive force, Figure 5The system employs a suction method. The first cover 180 is roughly cover-shaped and fastens onto the lower finger clip 120. One end of the first cover 180 and the lower finger clip 120 are hinged together, and the other end is open, thus providing a certain amount of accommodating space. The upper finger clip 110, the electromagnetic pressure component 160, and the spring-loaded component can be placed at the open end. Because the first cover 180 is roughly cover-shaped, it can cover all the components being monitored, effectively isolating external natural light during detection and preventing interference from natural light to the signal transceiver.

[0075] like Figure 6 , Figure 7 As shown in the embodiment of this application, the first cover 180 is provided with a second mounting cavity 181 inside, the upper finger clip 110 is provided in the second mounting cavity 181, the bottom wall of the first cover 180 is provided with an opening at the position corresponding to the first clamping area 111, and the bottom wall of the first cover 180 is also provided with a second through hole 113 for the connecting post 130 to pass through.

[0076] in, Figure 6 To use a repulsive force, Figure 7 The suction method is employed. The first cover 180 has a second mounting cavity 181 inside the end that forms an opening with the lower finger clip 120, allowing the upper finger clip 110 to be placed within the second mounting cavity 181. Since the lower surface of the upper finger clip 110 has a first clamping area 111, an opening of similar size to the first clamping area 111 needs to be provided on the bottom wall of the first cover 180 to allow the first clamping area 111 to apply clamping force to the finger. Furthermore, the upper finger clip 110 is connected to the connecting post 130; therefore, the bottom wall of the first cover 180 also has a second through hole 113 for the connecting post 130 to pass through. The position and number of the second through holes 113 should be consistent with the position and number of the connecting post 130. The upper finger clip 110 is located behind the second mounting cavity 181 and can be fixedly connected to the first cover 180. The other end of the first cover 180 is hinged to the lower finger clip 120. Therefore, when the upper finger clip 110 clamps or opens, the first cover 180 can clamp or open along with the upper finger clip 110. Thus, whether in the clamped or open state, the first cover 180 can effectively block external light. In addition, since the upper finger clip 110 is located in the second mounting cavity 181, it can also provide protection for the upper finger clip 110 and the signal transceiver device on the upper finger clip 110 to a certain extent.

[0077] like Figure 8 , Figure 9As shown in the embodiment of this application, the monitoring device 100 further includes a second cover 190. One end of the second cover 190 is fixedly connected to the lower finger clip 120, and the other end is open to the lower finger clip 120. The upper finger clip 110 and the electromagnetic pressure assembly 160 are both located at the opening positions of the second cover 190 and the lower finger clip 120. The spring-opening assembly includes a plurality of second springs 141. The two ends of the plurality of second springs 141 are respectively connected to the upper surface of the upper finger clip 110 and the second cover 190. When the upper finger clip 110 and the lower finger clip 120 are in the clamping state, the plurality of second springs 141 are in the stretched state.

[0078] Specifically, one end of the second cover 190 is fixedly connected to the lower finger clip 120, and the other end is open to the lower finger clip 120. That is, the distance between the openings of the second cover 190 and the lower finger clip 120 is fixed. The arrangement of the electromagnetic pressure assembly 160, the upper finger clip 110, the lower finger clip 120 connecting post 130, and the first bellows 150 is the same as... Figure 4 , Figure 5 Maintain consistency, including the suction method used (e.g.) Figure 9 Or should we use a repulsive force method (such as...) Figure 8 The difference lies in the installation location of the pop-up component. For example... Figure 8 , Figure 9 As shown in this embodiment, the spring-opening component is located above the upper finger clip 110. Specifically, the spring-opening component may include two second springs 141, which are located on either side of the first clamping area 111. One end of each second spring 141 is connected to the upper finger clip 110, and the other end is connected to the second cover 190. When the upper finger clip 110 and the lower finger clip 120 are clamped, the two second springs 141 are stretched. When the upper finger clip 110 and the lower finger clip 120 lose their attractive or repulsive force, the two second springs 141 instantly contract, thereby causing the upper finger clip 110 and the lower finger clip 120 to spring open rapidly. This type of spring-opening component also has the effect of quickly springing open the upper finger clip 110 and the lower finger clip 120. Furthermore, it should be noted that in this configuration, the number of second springs 141 is not specifically limited, and a second corrugated tube 151 can be sleeved on the outside of the second springs 141 to prevent the second springs 141 from being directly exposed.

[0079] like Figure 1 As shown in the embodiments of this application, a microcirculation monitoring system for hemorrhagic shock is also proposed, including the microcirculation monitoring device 100 for hemorrhagic shock described in any of the above embodiments. The monitoring system further includes:

[0080] A wearable monitoring device 200 is provided, which is equipped with an onboard power supply 260. The wearable monitoring device 200 is electrically connected to the hemorrhagic shock microcirculation monitoring device 100. The wearable monitoring device 200 is used to supply power to the hemorrhagic shock microcirculation monitoring device 100 and control the hemorrhagic shock microcirculation monitoring device 100 to perform monitoring.

[0081] like Figure 1 As shown in this embodiment, the wearable monitoring device 200 is a wristband, which is electrically connected to the monitoring device 100. The wristband is equipped with an onboard power supply 260, which can power the monitoring device 100, such as the electromagnetic pressurization component 160, the pressure sensor 170, the first signal transceiver 112, and the second signal transceiver 122.

[0082] like Figure 10 As shown in this embodiment, the wristband can also be equipped with a first MCU module 230. The first MCU module 230 is connected to the electromagnetic pressurizing component 160, the pressure sensor 170, the first signal transceiver 112, and the second signal transceiver 122 via an AD conversion module 240. Thus, the first MCU module 230 can control the monitoring device 100 to monitor the subject. For example, the first MCU module 230 can control the electromagnetic pressurizing component 160 to perform a clamping action, control the clamping force of the electromagnetic pressurizing component 160, control the first signal transceiver 112 to send signals, receive signals received by the second signal transceiver 122, calculate the refill time, and receive the clamping force detected by the pressure sensor 170.

[0083] Continue to refer to Figure 10 In this embodiment, the wearable monitoring device 200 also includes a first display screen 210, which is connected to the first MCU module 230. The first display screen 210 can display relevant information about the monitoring device 100 and the wearable monitoring device 200. For example, it can display the current battery level of the onboard power supply 260, the clamping force detected by the pressure sensor 170, and the recharge time calculated by the first MCU module 230. By setting up the first display screen 210, various information can be displayed intuitively, making it convenient to use.

[0084] like Figure 1 As shown in the embodiment of this application, the monitoring system further includes a device management box 300, which is communicatively connected to multiple wearable monitoring devices 200; the device management box 300 is also provided with a second display screen 310, which is used to receive and display the monitoring data of the monitoring device 100 corresponding to each wearable monitoring device 200.

[0085] Specifically, such as Figure 10 As shown, the wearable monitoring device 200 is equipped with a first communication module 220, and the device management box 300 is equipped with an onboard power supply 350, a second MCU module 320, and a second communication module 330. The onboard power supply 350 can supply power to the device management box 300, and the first communication module 220 and the second communication module 330 can communicate wirelessly. For example, both the first communication module 220 and the second communication module 330 can be Zigbee communication modules. By setting up a host computer communication module (such as a 458 communication module), the first communication module 220, the second communication module 330, and the host computer can be networked to form a large-scale wireless communication network for network communication between the first communication module 220 and the second communication module 330.

[0086] Continue to refer to Figure 10 In this embodiment, the wearable monitoring device 200 is further provided with a first charging and discharging module 250, the device management box 300 is provided with multiple charging compartments 380, each charging compartment 380 is provided with a second charging and discharging module 340, and the device management box 300 is provided with an on-board power supply 350. The on-board power supply 350 has a larger capacity than the onboard power supply 260. Therefore, when the wearable monitoring device 200 is placed in the charging compartment 380 of the device management box 300, the wearable monitoring device 200 can be charged through the first charging and discharging module 250 and the second charging and discharging module 340.

[0087] Continue to refer to Figure 10 In this embodiment, the device management box 300 further includes a second display screen 310, which is connected to the second MCU module 320. The second display screen 310 can display relevant information about the device management box 300. For example, it can display the remaining power of the onboard power supply 350, network communication status, and the usage status of each charging compartment 380. The second display screen 310 can also display information about each wearable monitoring device 200 that is communicatively connected to the device management box 300. For example, each wearable monitoring device 200 is connected to a first display screen 210, and the content displayed on the first display screen 210 can be sent to the device management box 300 through the first communication module 220. After receiving the information from each wearable monitoring device 200, the device management box 300 displays it on the second display screen 310.

[0088] By setting up an equipment management box 300 and establishing communication connections with multiple wearable monitoring devices 200, the information monitored by each monitoring device 100 can be managed uniformly. This is particularly useful in complex on-site environments such as natural disasters, accident scenes, and battlefields, facilitating the monitoring of the injured and improving management. Furthermore, the equipment management box 300 is equipped with an onboard power supply 350, which can charge each wearable monitoring device 200, enabling convenient use in on-site environments without power.

[0089] Continue to refer to Figure 10 In this embodiment, the device management box 300 is also equipped with an alarm, such as a sound alarm or a light alarm, or a sound and light integrated alarm. The alarm is connected to the second MCU module 320. When the second MCU module 320 detects that a monitoring device 100 has abnormal monitoring information, it issues an alarm to remind the staff to check.

[0090] like Figure 1 As shown, the device management box 300 is roughly a flip-top structure. Each charging compartment 380 is set on one side of the flip-top, and a second display screen 310 is set on the other side of the flip-top. The second display screen 310 can rotate to close each charging compartment 380, so that each wearable monitoring device 200 and monitoring device 100 can be placed in each charging compartment 380 during transportation and storage, and the second display screen 310 can be used to close the compartment, which facilitates storage and transportation.
