The isolation column 126 may be made of a non-metal non-conductive material, and is used for isolating and installing the filter circuit 122 from the shielding box 121, so that the filter circuit 122 is insulated and not grounded when performing defibrillation rescue.

With continued reference to fig. 6 to 8, the grounding connection member 13 is disposed through the shielding box 121, and an end portion (a left end as shown in fig. 8) of the grounding connection member 13 disposed in the shielding box 121 is connected to the filter circuit 122, so as to realize whether the filter circuit 122 is grounded, so that the filter circuit 122 is grounded when the life value is monitored, and the filter circuit 122 is disconnected from ground when defibrillation is performed. Specifically, the grounding connectors 13 are disposed on the side plate of the shielding box 121 in a one-to-one correspondence manner, for example, may be disposed on the side plate (the right side plate shown in fig. 4) facing the sliding shielding compartment 2, one end (the left end shown in fig. 8) of the grounding connector 13 is connected to the corresponding filtering circuit 122, may be connected to the filtering circuit 122 by welding, may use elastic sheets or conductive elastic sheets for grounding the filtering circuit 122, and the other end (the right end shown in fig. 8) is used for selectively grounding, that is, by closing or opening the shielding compartment front cover 22, the connection or disconnection between the other end of the grounding connector 13 and the shielding compartment front cover 22 is achieved, and then the grounding or disconnection of the corresponding filtering circuit 122 is achieved, so that the grounding connector 13 is grounded when the lead wire body 11 is subjected to electrocardiographic monitoring.

For example, when the shielding cabin front cover 22 is closed, the grounding connector 13 contacts with the shielding cabin front cover 22 to conduct electricity so as to enable the filter circuit 122 to be grounded, thereby realizing the effect of filtering external interference; when the object 4 to be detected needs to be defibrillated for rescuing, the shielding cabin front cover 22 is pulled open, and the filter circuit 122 is disconnected to the ground, so that the defibrillation current can be passed through the filtering circuit.

The grounding connection piece 13 may be further disposed at an interval between the right side wall of the filter circuit 122 and the right side plate of the shielding box 121, so that a gap is formed between the right side wall of the filter circuit 122 and the right side plate of the shielding box 121, that is, the left side and the right side of the filter circuit 122 are limited by the isolation post 126 and the grounding connection piece 13 respectively, so as to realize isolation with the shielding box 121.

In the present embodiment, an insulating pad 127 is provided between the ground connector 13 and the shield case 121 for insulating isolation between the shield case 121 and the ground connector 13. Specifically, the insulating pad 127 may isolate the ground connector 13 from the always grounded shielding box 121, thereby ensuring that the ground connector 13 is disconnected from the ground, and preventing the filter circuit 122 from being grounded during defibrillation.

In this embodiment, the electrocardiograph filter is mounted on the front fixed interface of the shielding cabin of the magnetic resonance system, so that the shielding box 121 contacts with the front fixed interface of the shielding cabin well.

The life monitoring equipment 5 outside the sliding shielding cabin 2 is connected to the butt joint snap fastener structure of the filter 12 through the self-contained monitoring lead wire 51, one end of the lead wire body 11 in the sliding shielding cabin 2 is connected to an electrode plate on the body of the object 4 to be monitored, and the other end is inserted into the filter 12. The life monitoring device 5 outside the sliding-type shielding compartment 2 is thus connected to the object 4 to be monitored inside the sliding-type shielding compartment 2 via the filter 12. After the shielding cabin front cover 22 is closed when the object 4 to be monitored is scanned, the grounding connection piece 13 on the electrocardio filter is contacted with the shielding cabin front cover 22 to realize grounding conduction of the filter circuit 122, and electrocardiosignals of the object 4 to be monitored are transmitted to the life monitoring equipment 5 for electrocardiographic monitoring display after being filtered by interference of the electrocardiosignals of the electrocardio filter. When the object 4 to be monitored is in vibration and needs to be rescued, the shielding cabin front cover 22 is pulled open, the grounding connecting piece 13 on the electrocardio filter is separated from the shielding cabin front cover 2, the filter circuit 122 is disconnected to the ground, and the life monitoring equipment 5 can be operated to defibrillate and rescue the object 4 to be monitored.

In summary, the defibrillation type lead wire and the magnetic resonance system provided in this embodiment can realize the monitoring of the life value of the object 4 to be monitored through the arrangement of the lead wire body 11, and can realize the grounding and disconnection of the filter 12 through the arrangement of the grounding connector 13, so that when the life value is monitored, the grounding connector 13 is grounded, the grounding of the filter 12 is realized, the external electromagnetic interference signal brought on the monitoring lead wire 51 can be filtered through the filter 12 to prevent the external electromagnetic interference signal from interfering with the magnetic resonance scanning in the sliding type shielding cabin 2, the sliding type shielding cabin 2 can provide a good shielding environment for the magnetic resonance to ensure that the magnetic resonance obtains excellent imaging, and a reliable basis is provided for treatment, so that the problem that the magnetic resonance scanning is inaccurate when the external interference is introduced into the shielding cabin of the magnetic resonance system through the lead wire by the existing monitor is solved, and the filter 12 can also filter the acquired monitoring signal to improve the accuracy of the monitoring signal; and when defibrillation is carried out, the grounding connecting piece 13 is disconnected, the disconnection and the grounding of the filter 12 are realized, defibrillation current is transmitted to the object 4 to be monitored through the lead wire body 11 and the filter 12, so that defibrillation rescuing of the object 4 to be monitored is carried out, the problem that when a patient needs defibrillation in the existing magnetic resonance examination scanning process, the patient needs to pull out from the magnetic resonance system and then carry out relevant rescuing so as to delay the rescuing time of the patient is solved, and the detection of the life value of the object to be monitored can be carried out continuously or intermittently in a short time while the magnetic resonance scanning is realized, and even the defibrillation of the patient can be carried out. The defibrillation lead wire and the magnetic resonance system have the following advantages: first, can be compatible with the ordinary monitor; secondly, the electrocardiograph monitoring is realized by a compatible magnetic resonance system; thirdly, the device has a defibrillation function and is easy to operate; fourth, the lead wire body 11 is easy to replace, and can be used as a special line for special people to prevent cross infection; fifth, the cost of use is greatly reduced, so that the cost of the defibrillation lead wire and the magnetic resonance system is low and easy to popularize.
