Description

Technical Field

[0001] The utility model relates to a medical electrical device, in particular to a modular medical electrical device with a magnetic interface. Background Art

[0002] The content of this part only provides background information related to the present disclosure, which may not constitute the prior art.

[0003] With the improvement of medical electrical devices, modular medical electrical devices are increasingly widely used due to their higher flexibility. Common modular medical electrical devices include modular patient monitors, ventilators, anesthesia machines, etc. Taking the kangaroo monitor as an example, the so-called "mother machine" and "sub-machine" in its daily application are the host and functional modules of the medical electrical device. In application, the selection of functional modules and parameters can be flexibly selected according to clinical needs. There are independent functional modules for each or each group of monitoring parameters. These functional modules can be connected to different interface positions of the monitor host to achieve power supply and signal transmission. The functional module can adopt an independent CPU unit. After the signal is processed by the CPU of the module itself, it is sent to the host bus. The host usually includes a main CPU, a shared bus, a display, a recorder, an audible and visual alarm, a keyboard controller, a memory, etc.

[0004] At present, the connection method between the module and the host of the modular medical electrical device mostly adopts a plug-and-slot connection. In actual use, this connection method often causes faults such as unstable power supply and data transmission interruption due to unstable engagement, and may also cause the module not to work or even be damaged due to reverse insertion of the interface. Especially in the case of first aid or a dim environment, the engagement difficulty and error rate are greatly increased.

[0005] Therefore, it is necessary to provide an improved connection scheme to overcome the above problems of the existing slot connection method, realize the quick connection and use of the functional module and the host in daily and extreme situations, and effectively avoid connection errors. Summary of the Utility Model

[0037] Detailed Embodiments

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. The same reference numerals are used in the various drawings to represent the same components, and thus the construction of the same components will not be described repeatedly.

[0040] Figure 1An existing modular medical electrical device 1 is shown, which mainly includes a main unit 10 and a plug-in functional module 20. Among them, the main unit 10 often includes a main unit housing and components such as a display unit, a main CPU control system, an input device, a memory, a communication device, and at least one independent module interface accommodated in the main unit housing; the functional module 20 can adopt an independent CPU unit, and the signals are processed by the CPU of the module itself and transmitted to the main CPU control system through electrical signals. Each functional module usually corresponds to a specific detection parameter, and according to the different detection objects, there can be various types of functional modules. Taking a kangaroo monitor as an example, its functional modules include, for example: an electrocardiogram module (ECG), a non-invasive blood pressure module (NIBP), a blood sample module (SPO2), a body temperature module (TEMP), an invasive blood pressure module (IBP), an anesthetic gas detection module (SAM), an end-tidal carbon dioxide module (ETCO2), etc. According to clinical needs, medical staff can flexibly select the corresponding functional modules to be connected to the main unit to achieve specific monitoring functions.

[0041] In the existing modular medical electrical device, a slot-type connection is used between the functional module and the main unit. As Figure 1 shown, a slot is provided on one side of the main unit housing. The user needs to manually place the functional module correctly into the slot, and the power supply and data interfaces need to be strictly aligned. Otherwise, it will cause a connection deviation. In the light case, the connection is not firm, resulting in power supply instability, data transmission interruption and other faults. In the serious case, the interface is inserted reversely, causing the module not to work or even be damaged. Especially in the case of first aid or a dim environment, this inconvenience may lead to the delay of the treatment opportunity.

[0042] Therefore, the inventor realized that if the connection interface between the functional module and the main unit can be further improved, the manual operation of people can be reduced, and the faster, more convenient and safer connection between the functional module and the main unit can be realized through the characteristics of the interface itself, thereby reducing the errors and damages during connection. This will greatly improve the performance of the modular medical electrical device and make it better meet the application requirements of various scenarios.

[0043] Based on the above principles and considerations, the inventor proposed a modular medical electrical device with a magnetic attraction interface to solve at least one of the above problems.

[0044] The following will refer to Figure 2 and Figure 3 to describe in detail the modular medical electrical device according to the first embodiment of the present invention.

[0045] Referring to Figure 2 , which shows an embodiment of the magnetic attraction interface of the modular medical electrical device according to the present disclosure. Figure 1Similar to the device, this medical electrical device of the module also includes: a main unit 10, which at least includes a main unit housing and a control system accommodated in the main unit housing; and at least one functional module 20, which can be electrically connected to the main unit 10 to transmit electrical signals with the main unit. Different from the prior art, in this embodiment, the main unit 10 and the functional module 20 are electrically connected via a magnetic interface. To simplify the illustration, the main unit 10 and the functional module 20 are omitted in Figure 2 and can be specifically referred to Figure 1 .

[0046] This magnetic interface includes a first magnetic interface and a second magnetic interface. Among them, the first magnetic interface is provided on one side of the functional module 20, and the second magnetic interface is provided on one side of the main unit 10.

[0047] Specifically, refer to Figure 2 and Figure 3 . The first magnetic interface includes a first housing 21 and first magnetic units 22, 23 provided on the first joint surface 210 of the first housing 21. The first magnetic units 22, 23 and the second magnetic units 12, 13 have magnetism, and the two magnetic units are correspondingly arranged so that the first magnetic interface and the second magnetic interface can only be joined to each other in a predetermined orientation under the action of magnetism to achieve electrical connection.

[0048] The first housing 21 and the second housing 11 have matching shapes so that when the magnetic interface is in the joined state, at least a part of the first housing 21 can be stably held in the second housing 11. Figure 2An exemplary manner is shown. As depicted in the figure, the first housing 21 is directly provided by the outer shell of the functional module 20. The second housing 11 is generally in a groove structure, which is defined by a second engaging surface 110 and peripheral walls 112, 114 that extend perpendicular to the second engaging surface 110 at the outer periphery of the second engaging surface 110. When it is necessary to engage the first magnetic interface with the second magnetic interface, one only needs to determine the correct orientation of the functional module 20 according to the arrangement of the first magnetic units 22, 23 and the second magnetic units 12, 13, and then bring the functional module 20 close to the opening of the second housing 11 along this orientation. When the two are close to within a certain distance range, under the traction of the magnetic attraction force between the first magnetic units 22, 23 and the second magnetic units 12, 13, the first magnetic interface can easily and automatically align with the second magnetic interface, thereby guiding the operator to accurately and quickly assemble the functional module 20 into the groove structure. In particular, during the assembly process, the closer the first magnetic interface is to the second magnetic interface, the greater the magnetic attraction force between the first magnetic units 22, 23 and the second magnetic units 12, 13, and the higher the alignment accuracy. When the first magnetic units 22, 23 and the second magnetic units 12, 13 are attracted together, the correct engagement of the first magnetic interface and the second magnetic interface is achieved. Therefore, compared with the existing connection method of plugs and sockets, this magnetic interface can greatly reduce the requirements for manual alignment and the difficulty of engagement by means of automatic alignment and fine-tuning by magnetic force, and thus can achieve convenient, fast, and accurate electrical connection between the functional module and the host.

[0049] In particular, in an actual modular medical electrical device, a host can be connected to multiple different functional modules. Due to different functions and test mechanisms, the connection interfaces between different functional modules and the host are usually different. In view of this situation, the modular medical electrical device according to the embodiments of the present disclosure can also include multiple different magnetic interfaces. For different functional modules, a second magnetic interface capable of adapting to the first magnetic interface of different functional modules 20 can be provided on the host 10 side. The second magnetic interface can include multiple second housings 11, and these second housings 11 can have different structures to adapt to multiple first housings 21 with different structures.

[0050] In the present disclosure, the "structure" of the housing includes, but is not limited to, the size and shape of the housing itself, and the shape and size of the engaging surface defined thereby. For example, different first housings may have different sizes or shapes, and each second housing may respectively have a size or shape adapted to one of the first housings. Advantageously, in this way, the first magnetic attraction interface of a functional module 20 can only be engaged with one second magnetic attraction interface on the host 10 side, and cannot be combined with other second magnetic attraction interfaces. Such a design will be very advantageous. By making the magnetic attraction interfaces of different functional modules have different housing structures, it is possible to quickly determine the magnetic attraction interface matching a functional module, avoiding connecting the functional module to the host via the wrong interface. On the one hand, it shortens the time for finding the interface, which is beneficial to the quick engagement of the interface. On the other hand, it avoids equipment damage caused by wrong engagement, ensuring the accuracy of the connection and the use safety of the equipment.

[0051] In addition, when the magnetic attraction engagement is in the engaged state, on the one hand, the magnetic attraction force between the first magnetic attraction units 22, 23 and the second magnetic attraction units 12, 13 always urges the first magnetic attraction interface and the second magnetic attraction interface to be correctly engaged together. On the other hand, each first housing 21 and the corresponding second housing 11 have a specific structure (including but not limited to shape and size) that matches each other, which further ensures that the first housing 21 is firmly held in the groove structure of the second housing 11. Therefore, through such magnetic engagement, it is not easy for the two magnetic attraction interfaces to become loose and fall off, which advantageously ensures the reliability and stability of the electrical connection between the functional module and the host, and further improves the use safety of the medical electrical equipment.

[0052] In this example, window portions 15 are provided on the peripheral walls 112 and 114 of the second housing 11. The window portions 15 can be formed by a partially disconnected or recessed peripheral wall. The setting of the window portions 15 is beneficial in that, on the one hand, during the process of bringing the first magnetic attraction interface and the second magnetic attraction interface close to each other to achieve engagement, it is convenient for the operator to observe the alignment of the two interfaces. On the other hand, it is convenient for the operator to apply a pulling force sufficient to overcome the magnetic attraction force to the first housing 21 when disconnecting the engagement.

[0053] When the magnetic attraction interface is in the engaged state, the first engaging surface 210 and the second engaging surface 110 are in an opposing engaged state. In this embodiment, the first magnetic attraction units 22, 23 include two first magnets 22A, 23A provided on the first engaging surface 210; the second engaging surface 110 includes second magnetic attraction units 12, 13, and the second magnetic attraction units 12, 13 include two second magnets 12A, 13A provided on the second engaging surface 110. It can be Figure 2 seen that the first magnetic attraction units 22, 23 and the second magnetic attraction units 12, 13 have corresponding structures.

[0054] Preferably, the first magnetic attraction units 22, 23 are arranged non - centrally on the first joint surface 210. Correspondingly, the second magnetic attraction units 12, 13 are arranged non - centrally on the second joint surface 110. As an example, as Figure 2 and Figure 3 shown, the first magnetic attraction units 22, 23 and the second magnetic attraction units 12, 13 are both arranged at an upper - biased position on the first joint surface 210 and the second joint surface 110, rather than at the central height. This non - central arrangement of the first magnetic attraction units 22, 23 and the second magnetic attraction units 12, 13 is beneficial during the joining process of the two interfaces. Especially when there are specific requirements for the installation orientation of the functional module, or when there are other elements to be joined on the magnetic attraction interface (such as power supply or signal contacts), according to the positions of the first magnetic attraction units 22, 23 and the second magnetic attraction units 12, 13, the correct orientation of the first magnetic attraction interface when docking to the second magnetic attraction interface can be easily determined, preventing the functional module from being connected to the host in the wrong orientation.

[0055] The magnetic attraction of the first magnetic attraction units 22, 23 and the second magnetic attraction units 12, 13 is provided by two first magnets 22A, 23A and two second magnets 12A, 13A. Each of the first magnets 22A, 23A and its corresponding second magnet 12A, 13A have opposite polarities at the ends facing each other. Refer to Figure 2 and Figure 3 , the first magnetic attraction units 22, 23 further include two recesses 22B and 23B formed by indenting inward from the first joint surface 210, and the first magnet 22A and the first magnet 23A are respectively firmly embedded in the two recesses 22B and 23B. The second magnetic attraction units 12, 13 further include two bosses 12B and 13B protruding from the second joint surface 110, and the second magnet 12A and the second magnet 13A are respectively firmly embedded in the bosses 12B and 13B. The bosses 12B, 13B and the recesses 22B, 23B have a matching structure, that is, they have matching positions, dimensions and shapes, so that when the magnetic attraction interface is in the joined state, the bosses 12B, 13B are respectively stably held in the recesses 22B, 23B. Through the cooperation of the bosses 12B, 13B and the recesses 22B, 23B, the reliability and stability of the magnetic attraction interface are further enhanced, and the use safety of the medical electrical equipment is improved.

[0056] According to actual requirements, for example, considering that functional modules may have different volumes, shapes, and weights, different numbers of magnets can be set for the magnetic attraction units of different functional modules. For example, each magnetic attraction unit can include only one magnet, or can include three, four, or more magnets. In addition, the shape of the magnet is not limited to circular, and can also be strip-shaped, square, oval, etc. In addition, the positions of the concave seats and the convex platforms can be swapped, that is, two concave seats can be arranged on the second joint surface, and two convex platforms can be arranged on the first joint surface. Even for the sake of manufacturing simplicity, the convex platforms and the concave seats can be omitted, and the magnets can be directly mounted on the joint surface.

[0057] In an embodiment according to the present disclosure, the magnet can be any type of magnetic material or magnetic device selected according to actual needs, and at the same time, the magnetic force of the magnet can also be set according to actual needs. For example, the magnet can be a common type of permanent magnet, or can be an electromagnet with adjustable magnetism. In some cases, for example, when the application environment of the medical electrical equipment is relatively harsh, it may be beneficial to use an electromagnet with adjustable magnetism. For example, when used in an earthquake-prone area, the magnetic force can be appropriately increased to enhance the stability of the interface connection between the functional module and the host, so as to prevent the interface from loosening or even disconnecting during vibration.

[0058] See Figure 2 and Figure 3 , the magnetic attraction interface according to the first embodiment of the present disclosure further includes a power supply and signal contacts for realizing the transmission of electrical signals between the functional module 20 and the host 10. Among them, the first magnetic attraction interface includes the first power supply and signal contacts 24, the second magnetic attraction interface includes the second power supply and signal contacts 14, and the first power supply and signal contacts 24 and the second power supply and signal contacts 14 are correspondingly arranged such that when the first magnetic attraction interface is joined to the second magnetic attraction interface, the first power supply and signal contacts 24 and the second power supply and signal contacts 14 are in contact and achieve electrical connection. Although in this embodiment, the first power supply and signal contacts 24 and the second power supply and signal contacts 14 are respectively arranged on the first joint surface 210 and the second joint surface 110, however, the arrangement method is not limited thereto. Optionally, the first and second power supply and signal contacts can also be arranged on the first magnetic attraction units 22, 23 and the second magnetic attraction units 12, 13, for example, correspondingly arranged on the concave seats and the convex platforms.

[0059] In addition, the magnetic attraction interface can further include a connection feedback device, which can be configured to make different responses according to different joining results of the magnetic attraction interface. It can be a common device such as an indicator light or a prompt sound, and issue corresponding prompts or alarms for situations such as successful connection, connection error, or incomplete connection. For example, when the magnetic attraction interface is connected incorrectly, the connection feedback device issues an alarm indication signal, and when the magnetic attraction interface is connected successfully, the connection feedback device issues a success indication signal.

[0060] Compared with existing plug - socket interfaces, the magnetic interface as described in this disclosure will greatly reduce the maintenance difficulty and cost. When the magnetic interface fails or is damaged, only the independent housing of the magnetic interface or the independent components on the housing need to be replaced, rather than replacing the relatively expensive circuit board. And through the magnetic interface connection, the functional module can be easily separated from and assembled to the host, facilitating the movement of the functional module for carrying and expanding the application scenarios and scope. In addition, by using the magnetic interface, the characteristics of mutual attraction or repulsion between magnetic poles can be utilized to automatically align and fine - tune the two interfaces for correct engagement, enabling faster, more convenient, and safer connection compared with existing interfaces, reducing errors and damage during connection, and can simplify the appearance design of the host and the functional module, reduce the manufacturing difficulty and cost, and avoid interface connection problems caused by manufacturing errors of mating components (such as the guide rails on the slots).

[0061] Although in the first embodiment according to the present disclosure, the first housing 21 is directly provided by the housing of the functional module 20, the present disclosure is not limited thereto. The first housing of the first magnetic interface can be an independent housing assembled to the housing of the functional module, or the first housing can also be electrically connected to the functional module via a data transmission line. Similarly, the second housing of the second magnetic interface can be integrally formed on the host housing, for example, provided by a groove portion on the host housing, or can be an independent housing assembled to the host housing, or the second housing can also be electrically connected to the host via a data transmission line.

[0062] Hereinafter, reference will be made to Figure 4 Describe in detail the medical electrical equipment according to the second embodiment of the present utility model. Only the parts different from the first embodiment will be described below, and the same parts will not be repeated.

[0063] In an embodiment according to the present disclosure, the second magnetic interface is in the form of an integrated docking station 40, wherein the second housing 41 of the second magnetic interface is electrically connected to the host via a data transmission line 50, specifically, connected to the display 30 of the host. In particular, the second housing 41 of the second magnetic interface includes a second engagement surface 410 and a plurality of second magnetic units 42, 43 and second power and signal contacts arranged side by side on the second engagement surface 410.

[0064] The integrated magnetic adsorption interface according to the second embodiment of the present disclosure will have all the advantages of the magnetic adsorption interface of the foregoing first embodiment, and further has at least the following advantages: First, by using a data transmission line to connect the second magnetic adsorption interface to the host, compared with setting the second magnetic adsorption interface on the host housing, the volume of the host is greatly reduced, and the manufacturing cost of the device is reduced; Second, the maintenance difficulty and cost are further reduced. When the magnetic adsorption interface fails, the magnetic adsorption interface can be directly repaired or replaced without a large amount of disassembly and assembly work and replacing a relatively expensive circuit board; Third, by setting an integrated second magnetic adsorption interface, the host can easily achieve electrical connection with multiple functional modules in a cost-saving and space-saving manner.

[0065] Although the multiple second magnetic adsorption units 42, 43 shown in the figure have the same structure, each of the second magnetic adsorption units 42, 43 includes two second magnets 42A, 43A and bosses 42B, 43B that support the second magnets 42A, 43A. However, preferably, according to the actual structure of the first magnetic adsorption unit to be adapted, the multiple second magnetic adsorption units, as well as the second power supply and signal contacts, can have different structures to adapt to multiple first magnetic adsorption units with different structures. In the present disclosure, the "structure" of the magnetic adsorption unit includes but is not limited to: the shape, size, number, arrangement of the magnets, the shape, size, number, position of the recesses and bosses, and the form, position, etc. of the power supply and signal contacts. For example, corresponding to different first magnetic adsorption units, each second magnetic adsorption unit can have a different arrangement position. Especially when the first and second magnetic adsorption units each include multiple magnets, the multiple first magnets can be arranged non-equidistantly and / or asymmetrically on the first joint surface. Correspondingly, the multiple second magnets are arranged non-equidistantly and / or asymmetrically in the area of the second joint surface that docks with the first joint surface; and / or, the polarities of the multiple first magnets exposed on the first joint surface can be different, and corresponding to the polarities of the multiple first magnets, the polarities of the multiple second magnets exposed on the second joint surface are also different; and / or, the shape of the magnets, the shape of the recesses and bosses, etc. in each magnetic adsorption unit can be different.

[0066] Each magnetic attraction unit has a different arrangement, such that only the first magnetic attraction unit and the second magnetic attraction unit with the same arrangement can be mated and engaged. Moreover, due to the special arrangement of the magnets in the engagement surface, each pair of matching first and second magnetic attraction units can be successfully engaged only in a predetermined orientation. This design is also very advantageous. On the one hand, it greatly improves the accuracy of interface connection, avoids connecting the functional module to the host via the wrong interface, and avoids equipment damage caused by wrong engagement, ensuring the safe use of the equipment. On the other hand, since each magnetic attraction unit has a specific configuration that is easy to identify, the corresponding first and second magnetic interfaces can be easily matched, shortening the time to find the interface, facilitating the quick engagement of the interface, and improving the equipment usage efficiency.

[0067] In this example, the second housing 41 also includes a window portion 45.
