Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to an eye light perception monitoring device for after orbital surgery. Background Art

[0002] During orbital surgery and the postoperative recovery process, it is very important to promptly detect and handle intraorbital hemorrhage. Because hemorrhage can compress the optic nerve or blood vessels, resulting in vision loss or even blindness. If intraorbital hemorrhage can be promptly detected and handled, such complications can be avoided. However, the affected eye is usually bandaged after surgery, and it is generally impossible to check the vision with a vision chart. Therefore, clinically, vision light perception monitoring is generally performed to promptly obtain the vision changes of the patient, and then evaluate and promptly handle the intraorbital hemorrhage situation. When using a flashlight for monitoring in the past, sometimes false negatives occurred due to thick gauze or blood oozing from the gauze blocking, or due to the low battery power of the nurse's flashlight resulting in uncertain light perception. In addition, when measuring the light perception of the affected eye, the healthy eye needs to be covered. Sometimes, false positives occurred due to insufficient occlusion, resulting in light entering the healthy eye.

[0003] Taking the patent with the publication number CN209548227U and the patent name "Eye Light Perception Detection Bandaging Device for after Orbital Surgery" as an example. It discloses a light-sensitive device similar to an eye mask, and related structures such as a lithium battery, a switch, and LED lamp beads are arranged inside the light-sensitive device. However, such a structure, due to the integrated design, integrates all functional components into a structural whole, resulting in difficulty in disassembling during use, high overall production costs due to complex structure, and inconvenient disinfection after use. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a split-type eye light perception monitoring device for after orbital surgery, which makes the detection more convenient.

[0005] The technical solution adopted by the utility model to solve its technical problem is: an eye light perception monitoring device for after orbital surgery, including a transmitting end and a receiving end, and the transmitting end and the receiving end are independent structures from each other; the transmitting end includes a transmitting part and a holding part, the transmitting part includes a transmitting end resonance module and a power supply, and the transmitting end resonance module is connected to the power supply; the holding part includes a holding part housing, and the transmitting part is arranged inside the holding part housing; the receiving end includes a receiving end resonance module, and the receiving end resonance module includes an LED lamp; the transmitting end resonance module lights up the LED lamp of the receiving end resonance module through resonance excitation.

[0006] Furthermore, the receiving end includes a receiving housing, and the receiving end resonance module is arranged inside the receiving housing.

[0007] Furthermore, the bottom of the receiving housing is provided with a lower surface of the receiving housing that bends inwardly into the receiving housing, and the curved surface of the lower surface of the receiving housing is adapted to the outer contour of a human eye.

[0008] Furthermore, the radius of curvature of the receiving lower surface ranges from R20 to R30.

[0009] Furthermore, the thickness of the receiving housing of the receiving housing ranges from 4 to 10 mm.

[0010] Furthermore, the holding portion housing includes an upper shell and a lower shell, and the upper shell and the lower shell are detachably connected by a snap.

[0011] Furthermore, it includes a rectifying and filtering module disposed in the holding portion housing, and the transmitting end resonant module is connected to the power supply through the rectifying and filtering module.

[0012] Furthermore, the minimum distance between the transmitting end and the receiving end is less than or equal to 50 mm.

[0013] Furthermore, the receiving end resonant module includes a receiving end resonant capacitor and a receiving end resonant coil, and the LED lamp is connected to the receiving end resonant capacitor and the receiving end resonant coil.

[0014] The beneficial effects of the present utility model are as follows: In actual use, since the transmitting end and the receiving end are independent structures from each other, therefore, the receiving end can be disposed on the eye to be detected, while the transmitting end is at a certain distance from the receiving end and emits an excitation signal to the receiving end. After receiving the signal, the LED lamp lights up, thereby completing the visual light perception monitoring.

[0015] The independent structures from each other can allow the eye to be detected to be detected separately, while completely covering the healthy eye, thereby preventing the false positive situation caused by the light entering the healthy eye due to incomplete occlusion. At the same time, the LED lamp is close enough to the eye to be detected, so that the light generated by the LED lamp can fully enter the eye to be detected, preventing the false negative caused by the uncertain light perception.

[0016] The present utility model is particularly applicable to the ocular light perception monitoring after orbital surgery. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manners

[0024] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0025] As Figures 1 to 6 shown, it is a schematic diagram of an embodiment of an eye light perception monitoring device for after orbital surgery. The device mainly includes a transmitting end 26 and a receiving end 23. The transmitting end 26 and the receiving end 23 are independent structures from each other, thus realizing the independent use between the transmitting end 26 and the receiving end 23, greatly improving the flexibility of use of the device and making the monitoring process more convenient. During actual use, as Figure 1As shown, the eyeball 25 to be detected, that is, the eyeball to be detected after surgery, is generally bandaged with two layers of gauze, namely the lower layer of gauze 24 and the upper layer of gauze 22. Among them, when bandaging the above two layers of gauze, the receiving end 23 can be placed between the two layers of gauze, and the lower layer of gauze 24 and the upper layer of gauze 22 can fix the receiving end 23. Subsequently, when it is necessary to monitor the patient's vision, the transmitting end 26 is placed above the eyeball 25 to be detected, and the switch 14 on the transmitting end 26 is turned on. The transmitting end resonance module 16 of the transmitting end 26 lights up the LED lamp 7 of the receiving end resonance module 231 through resonance excitation. After the patient's affected eye, that is, the eyeball 25 to be detected, senses the light, the eyeball generates a reaction under the light stimulation, thereby realizing the monitoring of vision changes, as well as evaluating and promptly dealing with the situation of orbital hemorrhage. Since the receiving end 23 and the transmitting end 26 are independently set, the receiving end 23 can be independently set in front of the eyeball 25 to be detected, greatly reducing the corresponding installation difficulty and also reducing the pain of the patient during the detection process. In addition, the transmitting end 26 and the receiving end 23 are independent structures, and after one of the transmitting end 26 or the receiving end 23 is damaged, only the damaged part needs to be replaced separately, greatly reducing the replacement cost. Generally, as Figure 1 shown, the induction distance H2 between the transmitting end 26 and the receiving end 23 is limited to be less than or equal to 50 mm to ensure that the above resonance excitation can be carried out normally.

[0026] Regarding the above resonance excitation, the existing resonance excitation method can be adopted. Of course, the existing ultrasonic coupling wireless power transmission technology or electromagnetic induction coupling wireless power transmission technology can also be adopted, and then the electric energy is emitted from the transmitting end 26 and transmitted to the receiving end 23. Taking Figure 2 as shown, a power supply 13 can be selected to be set at the transmitting end 26. This power supply can be 220V alternating current for conventional civil use, and the alternating current is rectified and filtered by the rectification and filtering module 17 and then sent to the transmitting end resonance module 16 as direct current. Next, a resonance induction is generated between the transmitting end resonance module 16 and the receiving end resonance coil 5, and then the LED lamp 7 of the receiving end 23 is lit. Of course, the above power supply 13 can also be a 23A 12V battery, or a lithium polymer battery or a lithium-ion battery. The LED lamp 7 can be selected from high-power lamp beads, through-hole lamp beads or surface-mount lamp beads, and its power range is preferably 1 - 5W, and the color of the lamp beads can be white. In Figure 5 , the LED lamp 7 is a surface-mount lamp bead with a power of 3W.

[0027] Figure 3 and Figure 4As shown, it is a holding part housing formed by snapping together an upper shell 11 and a lower shell 18. The holding part housing mainly includes a rod-shaped handle part and an annular housing part for arranging a transmitting-end resonance module 16. A power supply 13 and a rectifying and filtering module 17 connected thereto are arranged inside the housing of the handle part. The transmitting-end resonance module 16 inside the annular housing part is also designed to be annular and is connected to the rectifying and filtering module 17. At a position on the upper shell 11 corresponding to the power supply 13, a detachable battery cover 12 can be arranged to facilitate the installation and removal of a lithium polymer battery or a lithium-ion battery. There is a linkage relationship between the indicator light 15 and the switch 14. When the switch 14 is closed, the indicator light 15 lights up, indicating that the transmitting-end resonance module 16 is working. Conversely, when the switch 14 is disconnected, the indicator light 15 goes out. Correspondingly, as Figure 5 and Figure 6 shown, after the receiving-end resonance capacitor 6 and the receiving-end resonance coil 5 of the receiving-end resonance module 231 of the receiving end 23 receive the above resonance excitation, the LED light 7 of the receiving-end resonance module 231 lights up. Among them, the switch 14 is generally a micro switch, which only plays the role of opening and closing the circuit. In order to more accurately monitor the change of the patient's vision, the switch 14 can be set as a multi-gear sliding switch. The multi-gear sliding switch has an internal resistor. At different gears, the transmitting end emits different powers, so that the brightness of the receiving-end LED is different, achieving the purpose of accurate monitoring.

[0028] As Figure 6 shown, it is a structural embodiment of the receiving end 23. Among them, in order to facilitate the better adaptation of the lower surface 21 of the receiving housing to the arc surface around the eye surface of the eye ball 25 to be detected, the lower surface 21 of the receiving housing can be selected as a curved surface that bends inward into the receiving housing 19. Preferably, the curvature radius range of the lower surface 21 of the receiver is preferably from R20 to R30. Figure 6 As shown, the preferred range of the overall thickness H1 of the receiving housing of the receiving end 23 is 4 - 10 mm, and the preferred range of the overall outer diameter D1 of the receiving housing of the receiving end 23 is 20 - 30 mm. The material of the receiving housing 19 is preferably medical-grade transparent ABS, PP, PC, and epoxy resin, etc., with a Shore hardness of 50A - 90A. The transparent material may cause the light source to be relatively dazzling, so the lower surface will be frosted or a light diffusing plate will be added to disperse the light source. In this embodiment, the receiving housing 19 of the receiving end 23 is made of medical-grade epoxy resin, with a Shore hardness of 90A, the outer diameter D1 of the receiving housing is 24.7 mm, and the thickness H1 of the receiving housing is 6.5 mm. The curvature radius R24 of the lower surface 21 of the receiver. The curvature radius R24 can make the lower surface 21 of the receiver fit better with the eye surface of the eye ball 25 to be detected. In order to increase the fitting strength, a function with an adhesion effect can also be designed on the lower surface 21 of the receiver, such as a transparent double-sided tape.
