When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of methods and systems consistent with some aspects of the utility model as detailed in the attached claims.

[0026] The utility model proposes a corneal sensory meter, such as Figure 1 As shown, the corneal sensory measuring machine comprises a measuring pen assembly 1 and a measuring wire assembly 2 arranged in the cavity of the measuring pen assembly 1. The measuring pen assembly 1 has a pen-like appearance, and the measuring wire assembly 2 is a replacement assembly. Figure 1 This is a schematic diagram showing that the measuring piece assembly has not yet been placed into the measuring pen assembly.

[0027] In the embodiment of the present utility model, Figure 2 As shown, the measuring pen assembly 1 includes an appearance part and a sliding part, and the measuring line assembly 2 includes a line ear 22 and a measuring line 23; the line ear 22 and the measuring line 23 are integrated, and the user will replace them according to the use of the measuring line 23. The integrated design is more beneficial to the user and makes the operation of the measuring line 23 easier. In other words, by setting the measuring line assembly 2 as a replaceable assembly, it can be used to easily replace the measuring line 23 when it is damaged or needs to be replaced.

[0028] The exterior parts include a nozzle assembly 3, a rod 4, an end cover 5 and a rubber ring 6, and the sliding parts include an inner sleeve assembly 7, a nut 8, a push handle 9, an elastic pin 10 for fixing the push handle 9, and a spring 11.

[0029] Among them, the rod 4 is used to connect the mouth 31 and the end cover 5 in the mouth assembly 3, the nut 8 is connected to the double screw ferrule 73 in the inner sleeve assembly 7, the measuring line assembly 2 is arranged in the cavity of the inner sleeve assembly 7, the wire ear is fixed between the double screw ferrule 73 and the nut 8, the rubber ring 6 is arranged on the outside of the rod 4 and the side of the push handle 9 close to the mouth 31, and the push handle 9 is arranged in the groove in the measuring pen assembly 1.

[0030] It should be noted that, by fixing the wire ear between the double screw ferrule 73 and the nut 8 , the measuring line assembly 2 is fixed in the inner sleeve assembly 7 by the appearance shape of the wire ear 22 in the measuring line assembly 2 .

[0031] In the embodiment of the utility model, the inner sleeve assembly 7 includes a sleeve 71, an inner tube 72 disposed in the sleeve 71, and a double screw ferrule 73, and the double screw ferrule 73 includes a first ferrule and a second ferrule. That is, by providing the double screw ferrule 73, i.e., a connector with double threads, it is used to fix or support the pipeline (sleeve) and other components (measuring line assembly)

[0032] Correspondingly, in an embodiment of the utility model, the nozzle assembly 3 includes an outer tube 32, the outer tube 32 and the inner tube 72 serve as guides, the sleeve 71 is connected to the first ferrule, and the nut 8 is connected to the second ferrule, wherein the wire ear 22 in the measuring line assembly 2 is installed and fixed in the groove in the second ferrule in the double screw ferrule.

[0033] The outer tube 32 is arranged in the mouth hole of the mouth part 31 , and glue is added in the hole to connect and fix the outer tube 32 and the mouth part 31 .

[0034] In the embodiment of the present utility model, the spring 11 is arranged between the rod 4 and the inner sleeve assembly 7. It should be noted that if the spring 11 is not arranged, the sliding member will be displaced due to the influence of horizontal gravity.

[0035] In the embodiment of the utility model, the elastic pin 10 connects the push handle 9 and the sleeve 71. The sleeve 71 is provided with a spring groove, and the spring 11 is arranged in the spring groove.

[0036] In an embodiment of the present utility model, the length of the measuring line 23 is adjustable, and the length of the measuring line is adjusted by pushing the push handle. The measuring line 23 is made of flexible material, and the diameter of the measuring line 23 is 0.13 mm.

[0037] In the embodiment of the utility model, the measuring pen assembly 1 is provided with scale marks, and the scale marks are uniform scale marks. In other words, the scale marks are uniform scales, which can make the measuring pen provide more accurate and consistent readings when used. This design helps to improve the accuracy of measurement.

[0038] That is to say, the sliding part is assembled in the rod part 4, and can slide axially within a certain range in the rod part 4. By pushing the push handle 9 rigidly connected and fixed on the sliding part sleeve by the elastic pin 10 in the sliding part, the measuring line 23 installed and fixed in the sliding part (double screw sleeve and nut) by the wire ear 22 is driven to slide, and the indicating scale of the elongation of the measuring line 23 on the outer surface of the push handle 9 and the rod part 4 is observed. The inner tube 72 and the outer tube 32 guide the measuring line 23, thereby controlling the elongation of the measuring line 23. The rubber ring 6 is outside the rod part 4, used to fix the push handle 9 to prevent the unexpected axial sliding of the sliding part. When the push handle 9 is pushed, the pushed part is a groove, and the push of the push handle 9 can be achieved based on the groove.

[0039] In one embodiment of the utility model, a measurement method of a corneal sensory meter is also provided, the method comprising the following steps: determining that the patient meets the measurement conditions; making the measuring line touch the cornea vertically until the measuring line bends to a preset curvature; starting the test with a measuring line of a preset length, and if the patient has no feeling, gradually shortening the length of the measuring line for testing; repeating the above steps until the patient has a blinking response.

[0040] For example, ask the patient to sit and look straight ahead, or turn the eyeball slightly in the direction to be examined, and touch the cornea vertically with the measuring line until the measuring line is bent to a barely noticeable curvature (about 4% deflection). First use the longest measuring line of 60 mm for the test. If there is no feeling, shorten the measuring line by 5 mm and test again, and so on, until the patient has a blinking response.

[0041] That is, initially start the measurement with the fully extended measuring wire (the scale reading is 6 at this time). Touch the end of the measuring wire vertically to the corneal surface and apply slight pressure until the measuring wire is deformed to about 4% curvature (that is, the first observable curvature). Repeat the above operation, gradually reducing the length of the measuring wire until the patient has a blink reaction. For example, the conversion table of the length and pressure of the measuring wire can be referred to Table 1, where the average diameter of the measuring wire is 0.13mm.

[0042] It should be noted that the measuring principle of the corneal sensory meter is that when the material and size of the measuring wire are determined, the tip of the measuring wire reaches the same deformation state. The longer the wire is, the smaller the pressure on the cornea; the shorter the wire is, the greater the pressure on the cornea.

[0043] Among them, the corneal perception meter is suitable for testing the corneal perception sensitivity of patients with eye diseases, patients undergoing eye surgery and those wearing contact lenses.

[0044] Since the measuring line assembly is a replacement assembly, in the embodiment of the utility model, a step for replacing the measuring line assembly is also proposed. Specifically, the step for replacing the measuring line assembly includes: 1) Push the push handle to the zero scale position to remove the nut. 2) Unscrew the end cap and the nut in turn. 3) Take out the measuring line assembly that needs to be replaced. 4) Install the new measuring line in the measuring pen assembly. During installation, the measuring line should be rotated, and then the nut and the end cap should be tightened appropriately. It should be noted that in order to make the measuring line slide correctly in the tube, it is necessary to ensure that the measuring line is completely dry before installing the measuring line assembly. In order for the measuring line to extend normally, it is necessary to check whether the pipe mouth in the nozzle assembly is damaged to affect the extension of the measuring line before installing the measuring line. If there is damage that affects the extension of the measuring line, the nozzle assembly needs to be replaced. 5) Push the push handle forward and backward to check whether the measuring line moves freely in the inner tube. 6) Place the nozzle assembly on a flat surface (such as hardwood), push the push handle to align with the zero scale, ensure that the measuring line is fixed at the gray arrow, and cut the measuring line with a sharp blade. It should be noted that in order to ensure the stability of the measurement line, the corneal sensory meter needs to be left to stand for 1 hour before cutting the line; after the measurement line is cut, in order to avoid any risk of damaging the patient's eyeball, it is necessary to check whether the cutting surface of the measurement line is cut flat and clean. 7) Move the push handle back and forth to check whether the corneal sensory meter is working properly. For example, when the push handle is in the front limit position, the measurement line part outside the measurement pen is extended; when the push handle is in the front limit position, the measurement line part inside the measurement pen is still retained.

[0045] According to the corneal perception meter of the embodiment of the utility model, it includes a measuring pen assembly and a measuring wire assembly arranged in the cavity of the measuring pen assembly; wherein the measuring pen assembly has a pen-like appearance, including an appearance part and a sliding part, the measuring wire assembly includes a wire ear and a measuring wire, and the measuring wire assembly is a replacement assembly; the appearance part includes a mouth assembly, a rod, an end cover and an rubber ring, the sliding part includes an inner sleeve assembly, a nut, a push handle, an elastic pin for fixing the push handle, and a spring, the rod is used to connect the mouth and the end cover in the mouth assembly, the nut is connected to the double screw ferrule in the inner sleeve assembly, the measuring wire assembly is arranged in the cavity of the inner sleeve assembly, the wire ear is fixed between the double screw ferrule and the nut, the rubber ring is arranged on the outside of the rod and on the side of the push handle close to the mouth, and the push handle is arranged in a groove in the measuring pen assembly. The corneal sensory meter is provided with a replaceable measuring line component, so that when the measuring line is damaged or needs to be replaced, it can be easily replaced, thereby improving the maintainability and service life of the corneal sensory meter; by providing scale marks on the measuring pen component, the measurement results can be conveniently read and recorded, thereby improving the accuracy and convenience of measurement; by providing a spring and an elastic pin, the push handle can be automatically reset, thereby improving the operability and use experience of the corneal sensory meter; by providing an inner sleeve component and a double-screw ferrule, a stable connection between the measuring line component and the measuring pen component can be achieved, thereby improving the stability and reliability of the corneal sensory meter.
