Description

Technical Field

[0001] The invention belongs to the field of medical devices, relates to emergency rescue of comatose patients, and specifically relates to a pupil observation device for comatose patients. Background Art

[0002] The pupil refers to the opening in the middle of the iris, which is the gateway for light to enter the eye. It shrinks in bright light and dilates in dim light. The iris is composed of multiple smooth muscle units. The circular muscle layer around the pupil is controlled by the parasympathetic nerve fibers in the oculomotor nerve. When it contracts, it shrinks the pupil, so it is also called the pupillary sphincter. The peripheral part of the iris is the radial muscle fiber, which is controlled by the sympathetic nerve fibers ascending from the neck. When it contracts, it dilates the pupil, so it is also called the pupillary dilator. The size of the pupil can control the amount of light entering the eye. The diameter of the pupil of an average person can vary between 1.5-8.0mm. The human eye receives light stimulation under different brightness conditions by different photoreceptor cells in the retina. The rod cells that work in dim light are much more sensitive to light than the cone cells that work in bright light. Therefore, to see things in the dark, you only need to increase the amount of light entering the eye appropriately.

[0003] The characteristic of pupil light reflex is the bilateral effect, that is, if light is shone on one eye, in addition to the pupil shrinking in the shone eye, the pupil of the other side that is not shone also shrinks at the same time. The latter is the mutual inductive light reflex. Clinically, abnormal conditions such as disappearance of pupil light reflex, unequal pupils, and disappearance of mutual inductive pupil reflex can sometimes be seen. This is often the result of damage to a part of the reflex arc related to these reflexes.

[0004] During field first aid, it is often necessary to make a quick assessment of the patient by observing the patient's pupil's response to light. However, the actual situation is often that there are no professional medical staff on site, or during long-distance transportation by means of transportation, medical staff cannot accompany the patient in real time. In this case, medical staff cannot provide real-time first aid guidance to the on-site rescuers by observing the patient's pupil's response to light, thus wasting precious first aid time.

[0026] Specifically, the eye mask 1 is made of a flexible material, is foldable, and has a certain elasticity. The strap 2 is provided with a self-adhesive buckle 15 .

[0027] Specifically, the wetting liquid may be a known commonly used wetting liquid, such as a commonly used wetting liquid for contact lenses.

[0028] Specific embodiments of the present invention are given below. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of this application fall within the protection scope of the present invention.

[0029] Embodiment 1:

[0030] Following the above technical solution, Figures 1 to 3 As shown, this embodiment provides a pupil observation device for a comatose patient, comprising an eye mask 1 with a strap 2, wherein the eye mask 1 is provided with a pair of light reaction monitoring units 3 corresponding to the positions of the patient's eyes.

[0031] The light reaction monitoring unit 3 includes a base 4 fixed in the eye mask, one end of a support tube 5 is fixed on the base 4, the other end of the support tube 5 extends out of the inner surface of the eye mask 1, a transparent eyeball fitting membrane 6 is fixed on the other end of the support tube 5, a moistening sponge 7 is mounted on the support tube 5 between the base 4 and the eyeball fitting membrane 6, and a moistening liquid is adsorbed in the moistening sponge 7 to keep the eyeball fitting membrane 6 moistened;

[0032] A camera 8 is arranged on the base 4 in the support tube 5, and a light 9 which can be turned on and off at a fixed time is arranged on the base around the camera 8 in the support tube 5;

[0033] The base 4 is provided with a power source 10 , a wireless transmission module 11 and a timer 12 .

[0034] As a preferred solution of this embodiment, the light reaction monitoring unit 3 is sealed on the eye mask 1 by a plastic shell 13. A closed space is formed in the plastic shell 13. Due to the wetting liquid in the closed space, the entire space is wetted, ensuring the long-term wetting of the eyeball fitting membrane 6 when not in use. The plastic shell 13 has a certain strength, which can ensure that the light reaction monitoring unit 3 is not damaged during storage and transportation, especially the eyeball fitting membrane 6 therein. A traction strip is reserved on the plastic shell 13 to facilitate tearing off the entire plastic shell 13.

[0035] As a preferred solution of this embodiment, the height of the camera 8 is less than the height of the support tube 5. The specific height difference is designed according to actual needs to ensure that the camera 8 has enough field of view to fully capture the image of the eye area that the medical staff needs to observe.

[0036] As a preferred solution of this embodiment, an elastic band 14 is also provided in the middle of the eye mask 1 between the pair of light reaction monitoring units 3. This facilitates better adaptation to patients with different eye distances. A series of devices of different sizes can be provided according to patients of different body sizes. The distance difference between the eyes of people of the same body size is within a relatively small range, and this adjustment can be fully achieved through the elastic band 14.

[0037] Specifically, the power supply 10 is connected to the camera 8, the aiming light 9, the wireless transmission module 11 and the timer 12 for power supply; the wireless transmission module 11 is connected to the camera 8 for transmitting the image captured by the camera 8; the timer 12 is connected to the aiming light 9 for controlling the on and off time of the aiming light 9. The wireless transmission module 11 can also be a wireless transceiver module. The specific transmission and reception of wireless signals and the control of the on and off time of the aiming light 9 can all be done by known technical means.

[0038] As a preferred solution of this embodiment, there are multiple aiming lights 9, which are evenly arranged around the camera 8. The specific number and brightness of the aiming lights 9 are designed according to actual needs to ensure that the patient can be sufficiently stimulated to react to light.

[0039] As a preferred solution of this embodiment, the outer diameter of the eyeball fitting membrane 6 is greater than the outer diameter of the support tube 5, and the outer diameter of the eyeball fitting membrane 6 is less than or equal to the outer diameter of the moistening sponge 7. This ensures the moistening of the eyeball fitting membrane 6. The moistening sponge 7 is sleeved on the support tube 5 and can be compressed as needed, which is convenient and flexible and will not affect the installation of the eyeball fitting membrane 6.

[0040] When the present invention is used, the plastic shell 13 is first torn off from around the light reaction monitoring unit 3 by the traction strip 16 to release the seal of the light reaction monitoring unit 3, the eye mask 1 is held in one hand, and the eyelid of the comatose patient is pulled apart by the other hand, and the eyeball fitting membrane 6 is fitted on the eyeball of the comatose patient like wearing contact lenses. After the installation is completed in both eyes, the eye mask 1 is fixed by the strap 2. The eyeball fitting membrane 6 is located inside the eyelid, and the moistening sponge 7 is located outside the eyelid. During the monitoring process, it can continue to moisten the eyes of the comatose patient, avoiding damage to the eyes during a long monitoring process. The support tube 5 opens the upper eyelid and the lower eyelid of the critically ill patient by a certain distance. The light lamp 9 provides light stimulation to the pupil of the critically ill patient at a fixed time interval, and the pupil produces a corresponding light reaction under the light stimulation. The camera 8 collects the results of the light reaction in real time in the form of images or videos, and sends them to the remote monitoring center through the wireless transmission module 11. The medical staff of the monitoring center can observe the pupil position of the comatose patient and the results of the light reaction based on the images or videos, so as to monitor the condition of the comatose patient in real time, and can provide necessary first aid guidance to the on-site personnel in a timely manner when necessary or conditions permit.
