Description

Technical Field

[0001] The invention relates to the field of ear, nose and throat examination instruments, in particular to an ear, nose and throat multifunctional examination mirror. Background Art

[0002] When performing an ENT examination, a commonly used examination instrument is a forehead mirror, which is worn on the forehead via a headband, and then the position of the forehead mirror is adjusted via a double ball joint. The headband has poor air permeability and is uncomfortable to use. After long-term use, the double ball joint is prone to loosening, and the double ball joint is troublesome and inconvenient to adjust the position. In addition, traditional forehead mirrors for ENT examinations usually use concave mirrors with a fixed focal length. Doctors need to replace forehead mirrors of different specifications according to the examination site (ear canal or throat), which is cumbersome and inefficient. In the existing technology, some improvement schemes optimize the user experience by adding auxiliary light sources or adjusting the bracket, but none of them solve the core problem of immutable focal length.

[0031] like Figures 1-4 The multifunctional ENT inspection mirror 5 shown includes: a headband 1, a deformable inspection mirror 5 component and a position adjustment component.

[0032] like Figure 1 and Figure 2 As shown, a first connector 2 is provided at one end of the headband 1, and a second connector 3 is provided at the other end. The first connector 2 and the second connector 3 are detachably connected, and a breathable spacer 4 is provided on the inner side of the headband 1. The first connector 2 and the second connector 3 can be Velcro, and the breathable spacer 4 is a flexible airbag. In this way, when the headband 1 is worn, it can be kept a certain distance from the head to ensure breathability and wearing comfort.

[0033] like Figure 3As shown in the figure, the otoscope 5 assembly comprises the otoscope 5 and the mirror rod 6, the mirror surface of the otoscope 5 is a surface-plated reflective film memory alloy sheet, the memory alloy sheet is a low-curvature annular surface at normal temperature and a high-curvature concave surface when heated to a critical temperature, the otoscope 5 is internally provided with an electric heating element for heating the memory alloy sheet, the otoscope 5 is provided with a switch 7 connected with the electric heating element, and the back surface of the otoscope 5 is provided with the vertical mirror rod 6.

[0034] Specifically, the memory alloy sheet is a nickel-titanium memory alloy sheet, and the surface is plated with a high-reflective silver film. It is a low-curvature annular surface at normal temperature, suitable for close-range ear examination, which is an otoscope mode at this time. When the critical temperature (such as 40℃) is reached, it deforms into a high-curvature concave surface, suitable for deep throat illumination, which is a laryngoscope mode at this time.

[0035] The electric heating element is an electric heating wire, and the otoscope 5 is internally provided with a rechargeable battery connected with the electric heating wire. After pressing the switch 7, the battery supplies power to the electric heating wire, thereby rapidly heating the memory alloy sheet.

[0036] As shown in the figures, Figure 3 and Figure 4 The position adjustment assembly comprises a base 8, a driving element, a left clamping plate 9 and a right clamping plate 10. The back surface of the base 8 is connected with the headband 1, the front side of the base 8 is provided with the left clamping plate 9 and the right clamping plate 10, the mirror rod 6 is inserted between the left clamping plate 9 and the right clamping plate 10, the base 8 is provided with the driving element connected with the left clamping plate 9 and the right clamping plate 10, and the driving element is used to drive the two clamping plates to move towards each other to clamp and fix the mirror rod 6 or move away from each other to loosen the mirror rod 6.

[0037] Specifically, when loosening the mirror rod 6, the two clamping plates have a certain interval, at this time the mirror rod 6 can move up and down, forward and backward, horizontally rotate or tilt within the interval, so the mirror rod 6 has a high degree of freedom in position adjustment, and after adjustment, the two clamping plates clamp the mirror rod 6, so that the otoscope 5 can be fixed.

[0038] As shown in the figures, Figure 3 and Figure 4 The driving element comprises a screw rod 11 and a handle 12, the screw rod 11 is rotationally connected with the base 8, one end of the screw rod 11 is provided with the handle 12, the left rod segment of the screw rod 11 is provided with a first thread, and the right rod segment is provided with a second thread, the rotation directions of the first thread and the second thread are opposite; the left clamping plate 9 is provided with a first screw hole 13, the right clamping plate 10 is provided with a second screw hole 14, the first screw hole 13 is threadedly matched with the left rod segment, and the second screw hole 14 is threadedly matched with the right rod segment. The front side of the base 8 is provided with a horizontal anti-falling groove 15, and the left clamping plate 9 and the right clamping plate 10 are respectively provided with sliding blocks 16 matched with the anti-falling groove 15. Thus, by rotating the handle 12, the two clamping plates can be driven to move.

[0039] Furthermore, anti-slip pads 17 are respectively provided on the left clamping plate 9 and the right clamping plate 10 to improve the clamping and anti-slip effects.

[0040] Furthermore, a detachment prevention cover 18 is provided at the top of the left mirror lever 6. The length of the detachment prevention cover 18 in the left-right direction is greater than the maximum distance between the left and right clamping plates. A first baffle 19 extending rightward is provided at the right front end of the left clamping plate 9, while a second baffle 20 extending leftward is provided at the left front end of the right clamping plate 10. A first clearance hole 21 for the second baffle 20 to pass through is also provided at the right front end of the left clamping plate 9, while a second clearance hole 22 for the first baffle 19 to pass through is also provided at the left front end of the right clamping plate 10. This prevents the mirror lever 6 from dislodging from the distance between the two clamping plates when the mirror lever 6 is released.

[0041] In summary, this device achieves rapid focal length switching, multi-degree-of-freedom position adjustment of the inspection mirror 5, and long-term comfortable wearing through the memory alloy variable-focus inspection mirror 5, the clamping position adjustment structure, and the breathable headband 1 structure. It can be widely used in ENT examinations in outpatient clinics, emergency departments, and primary medical institutions.
