[0028] Example:

[0029] See also Figures 1 to 5 In the first aspect of the present embodiment, a magnetic electrical connection device 200 is disclosed, comprising: a male connector 210 having magnetism, a female connector 220 magnetically connected to the male connector 210, and a cable 230 connected to the female connector 220;

[0030] The male connector 210 includes a male shell 211 for fixedly connected to the shell 110 of the medical device, a plurality of magnetic parts 213 fixed to the side of the male shell 211 facing away from the female connector 220, and a plurality of electrical connectors fixed to the side of the male shell 211 facing away from the female connector 220, each electrical connector partially protruding from the surface of the male shell 211 on the side facing the female connector 220 and electrically connected to the female connector 220, and each electrical connector is also used to electrically connect to the electronic components of the medical device.

[0031] like Figures 3-5 As shown, in this embodiment, on the one hand, the magnetic component 213 and the electrical connector of the magnetic attraction electrical connection device 200 are fixedly arranged on the side of the male shell 211 away from the female connector 220. During assembly, the electrical connector is assembled on the male shell 211 so that one end of the electrical connector protrudes from the male shell 211, and the other end is electrically connected to the electronic components of the medical device through cables such as wires. Then, the magnetic component 213 and the electrical connector are fixedly connected to the male shell 211 at the same time to complete the assembly of the male connector 210, so that the magnetic male connector 210 can be quickly assembled on the defibrillator monitor 100 or other medical devices.

[0032] On the other hand, since a magnetic part 213 is provided on the male connector 210 of the magnetic electrical connection device 200, the male connector 210 and the female connector 220 can be magnetically connected, so that the electrical connection device 200 can be blindly plugged in and used, which simplifies the steps for medical staff to operate medical equipment and reduces the pressure on medical staff at work.

[0033] As an example, the magnetic part 213 in the male connector 210 can be a magnetic part 213 that has a magnetic moment and can generate a magnetic field, such as a magnet. The female connector 220 can be installed with a component that can be magnetically attracted to the magnetic part 213 in the male connector 210. The component has the same properties as the magnetic part 213. The component can be a magnet that can generate a magnetic field. The female connector 220 can also only be installed with materials with ferromagnetic properties, such as iron blocks, which can also be attracted to the magnetic part 213 in the male connector 210. However, to ensure that the magnetic attraction force between the male connector 210 and the female connector 220 is large enough, a sufficiently large pulling force must be applied to separate the male connector 210 and the female connector 220.

[0034] The magnetic member 213 and the electrical connector can be fixed to the male connector housing 211 by various fixing connection methods such as gluing, snap connection, etc. The electrical connector can be electrically connected to the electronic components of the medical device by various methods, such as the electronic components of the medical device can be electrically connected to the electrical connector by wires, or the electronic components of the medical device can be coupled to the connection between the housing 110 of the medical device and the male connector 210 and a conductive area is provided so that the electrical connector abuts against the conductive area.

[0035] The magnetic electrical connection device 200 of the present invention is used for electrical connection of a defibrillator monitor 100 or other medical equipment in emergency or portable situations, and is preferably used for an ambulance's on-board defibrillator monitor 100 and other on-board medical equipment.

[0036] Furthermore, if Figures 3-5 A first clamping portion 2111 is provided on one side of the male housing 211 facing the female connector 220, and the female connector 220 is provided with a second clamping portion 221 matching the clamping portion. The first clamping portion 2111 has an asymmetric shape along a cross section perpendicular to the length extension direction.

[0037] In the related art, the male connector 210 of the medical device is symmetrically arranged on the surface. When the female connector 220 for power supply is plugged into the male connector 210 in the medical device, the plugging direction may be reversed. On the one hand, if the male connector 210 and the female connector 220 are plugged in reverse, the user needs to try to plug in repeatedly, especially if the male connector 210 and the female connector 220 also have the function of transmitting data. The user needs to run the relevant functions of the medical device before confirming whether it is plugged in reverse, which greatly affects the work efficiency. On the other hand, the spring pins 212 in the male connector 210 and the female connector 220 correspond to different electrodes. If the male connector 210 and the female connector 220 are plugged in reverse, it will cause the positive and negative electrodes to be incorrectly connected, thereby causing damage to the electronic components inside the medical device. In this embodiment, the asymmetric shape of the first clamping portion 2111 along the cross section perpendicular to the length extension direction is a fool-proof design, which can effectively prevent the male connector 210 and the female connector 220 from being plugged in reverse.

[0038] As an example, the first clamping portion 2111 can be protruding or recessed, or partially protruding or recessed, from the side of the male head shell 211 toward the female connector 220, and the second clamping portion 221 can also be protruding or recessed, or partially protruding or recessed, from the side of the female connector 220 toward the male connector 210.

[0039] Furthermore, if Figure 4 As shown, each electrical connector at least passes through a portion of the first clamping portion 2111 .

[0040] Specifically, the electrical connector is a spring pin 212, and the first clamping portion 2111 can be provided on the male housing 211 in an area with a protruding electrical connector, and / or in an area without a protruding electrical connector. In this embodiment, the first clamping portion 2111 is provided on the male housing 211 in an area with a protruding electrical connector.

[0041] Further, as shown in Figures 4 and 5, the first clamping portion 2111 includes a plurality of connector protrusions 2111a, each electrical connector 2111a is a spring pin group having at least one spring pin 212, and the spring pin group is inserted into each corresponding connector protrusion.

[0042] In this embodiment, the first clamping portion 2111 includes three connector protrusions 2111a arranged at intervals, and the cross-sectional shapes of the three connector protrusions 2111a along the direction perpendicular to the length extension are all different. The multiple electrical connectors include three groups of spring pin groups, each spring pin group has a spring pin 212, and the connector protrusions 2111a are provided with corresponding assembly holes for each spring pin 212 to pass through.

[0043] It should be known that the multiple spring pins 212 in the same spring pin group can be of the same model or of different models. For example, in the present embodiment, one spring pin group has multiple spring pins 212 of two models, and the other two spring pin groups each have one spring pin 212.

[0044] Furthermore, if Figure 4 and 5 As shown, the cross-sectional shape of each joint protrusion 2111a along the direction perpendicular to the length extension direction is a closed figure composed of arcs and / or line segments.

[0045] It should be known that, perpendicular to the length extension direction, the cross-section of the first clamping portion 2111 is an asymmetric shape, and the cross-sections of multiple joint protrusions 2111a can be set to have different shapes to achieve an asymmetric state. The cross-section of a single joint protrusion 2111a can be set to be an asymmetric polygon. The asymmetric state can also be achieved by unevenly distributing the joint protrusions 2111a, so that the first clamping portion 2111 forms a fool-proof design, which effectively prevents the male connector 210 and the female connector 220 from being inserted reversely.

[0046] Furthermore, if Figure 3 As shown, a plurality of assembly channels 2114 are formed on the side of the male housing 211 away from the female connector 220, and each assembly channel 2114 matches each electrical connector and each magnetic component 213 one by one, and each electrical connector and each magnetic component 213 is passed through the corresponding assembly channel 2114. The assembly channel 2114 is used to preliminarily fix each electrical connector and each magnetic component 213.

[0047] Furthermore, if Figure 2 As shown, the male shell 211 has a receiving space, which is connected to the opening of the male shell 211 at the end away from the female connector 220. Each magnetic component 213 and each electrical connector are received in the receiving space. The end of the electrical connector close to the opening of the male shell 211 is used for welding to the connecting wire of the medical device. The receiving space is filled with resin and at least covers the welding point between the electrical connector and the connecting wire.

[0048] The assembly method of the male connector 210 is to assemble each electrical connector on the male connector shell 211 through the assembly channel 2114, weld the electrical connector to the connecting line of the medical device, assemble each magnetic component 213 on the male connector shell 211, fill the receiving space with resin so that each electrical connector and each magnetic component 213 are fixed on the male connector shell 211, and the resin covers the welding point between the electrical connector and the connecting line.

[0049] Since the resin covers the solder joints between the electrical connector and the connecting wire, the coupling between the electrical connector and the connecting wire is more secure, and the magnetic component 213 and the electrical connector can be fixed to the male shell 211 at the same time, reducing the steps of fixing each magnetic component 213 and each electrical connector to the male shell 211 one by one, making the assembly process simpler and smoother.

[0050] Furthermore, if Figure 2 As shown, a plurality of mounting ears 2113 are provided at one end of the male housing 211 away from the female connector 220 , and the mounting ears 2113 are used for being screwed to the housing 110 of the medical device.

[0051] Furthermore, if Figure 1 and 4 As shown, in the direction from the male connector 210 to the female connector 220, the cross section of the end of the female connector 220 away from the male connector 210 is a convex curved surface. The curved surface design reduces the edges and corners of the female connector 220, making it more comfortable to hold during use.

[0052] See also Figures 1 to 4 The second aspect of this embodiment discloses a defibrillator monitor 100, including the above-mentioned magnetic electrical connection device 200, a shell 110 and electronic components accommodated in the shell 110, the male connector 210 of the magnetic electrical connection device 200 is fixedly connected to the shell 110 on the side away from the female connector 220, and the electrical connector of the male connector 210 is electrically connected to the electronic components of the medical device.

[0053] Furthermore, if Figure 2 As shown, an assembly groove 120 for accommodating the magnetic electrical connection device 200 is provided on the shell 110, and the male connector 210 is fixed in the assembly groove 120. Preferably, the depth of the assembly groove 120 is greater than the thickness of the male connector 210, and the electrical connector is completely accommodated in the assembly groove 120, thereby avoiding the exposure of the magnetic component 213 and the conductive area of ​​the electrical connector to the outside of the shell 110, preventing the male connector 210 from absorbing small iron sheets or other ferromagnetic objects during use, thereby reducing the risk of leakage and short circuit.

[0054] Preferably, the length extension direction of the assembly slot 120 is parallel to the horizontal direction, and one end of the cable 230 is connected to both ends of the female connector 220 in the length extension direction of the assembly slot 120. This arrangement facilitates the insertion of the cable 230 of the female connector 220 into the male connector 210. If the assembly slot 120 and the corresponding male connector 210 are at the near-ground end of the defibrillator monitor 100, when in use, the cable 230 extends in length in the horizontal direction, thereby avoiding the situation where the near-ground end of the defibrillator monitor 100 is too narrow to fit the male connector 210 and the female connector 220.

[0055] Furthermore, if Figure 4 and Figure 6As shown, one end of the male shell 211 close to the female connector 220 is recessed along the edge to form a snap-in groove 2112. The housing 110 also includes a detachably connected snap-in shell 111. The snap-in shell 111 is provided with a snap-in opening, and the groove surface provided with the snap-in groove 2112 abuts against the edge of the snap-in opening.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
