Embodiment 1, referring to fig. 1 to 4, an eye opening alarm device for general anesthesia operation patients comprises a monitoring unit 1 and an alarm unit 2 which are connected through a lead.

Among them, the monitoring unit 1 can be attached to the eyelids of the patient, and the eye opening and eye closing actions are performed simultaneously according to the general situation, so that, when the eyes of the patient are monitored, the eyes on one side of the patient can be monitored, and therefore, the monitoring unit 1 can be attached to the eyes on any side of the patient, more specifically, the upper eyelid and the lower eyelid of the eyes on any side of the patient.

Of course, there are some people who have open and close their eyes, and it is generally preferable to attach the monitoring unit 1 to both R and L eyelids of the patient to improve the monitoring accuracy in order to make the monitoring more accurate.

The monitoring unit 1 specifically comprises an eye patch and a magnetic switch 12 arranged on the eye patch, wherein the magnetic switch 12 specifically comprises a magnetic suction head 121 and a switch body 122 with a contact 122a and a contact arm 122b, the magnetic suction head 121 and the switch body 122 with the contact 122a and the contact arm 122b are separately arranged and have a matching relationship, and both require a carrier, so that the eye patch comprises an upper eyelid patch 111 and a lower eyelid patch 112, the magnetic suction head 121 and the switch body 122 can be respectively and correspondingly arranged on the upper eyelid patch 111 or the lower eyelid patch 112, the magnetic suction head 121 can be arranged on the lower eyelid patch 112, the switch body 122 is arranged on the upper eyelid patch 111, or the magnetic suction head 121 is arranged on the upper eyelid patch 111, and the switch body 122 is arranged on the lower eyelid patch 112.

However, it is obvious that the magnetic attraction head 121 is disposed on the lower eyelid adhesive film 112, and the switch body 122 is disposed on the upper eyelid adhesive film 111, so that the operation and feedback efficiency is higher, because the muscle action amplitude of the upper eyelid is larger and the monitoring is more sensitive compared to the lower eyelid when the eye is open.

Referring to fig. 2 to 3, the fitting relationship between the magnetic attraction head 121 and the switch body 122 is as follows: when the patient is in the eye-closing state, the magnetic attraction head 121 is closer to the switch body 122, and under the action of the magnetic attraction head 121, the contact arm 122b of the switch body 122 is attracted by the magnetic attraction head 121 and is disconnected from the contact 122a, accordingly, when the eye of the patient is opened, the contact arm 122b is pulled away from the magnetic attraction head 121 under the action of the eyelid separation force, and returns to touch the contact 122 a.
