DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Next, the working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0021] refer to Figure 1 A wearable intraocular pressure measurement device includes a tonometer 1, a fixed frame 2, a connecting strap 3, and an elastic strap 4. The fixed frame 2 is provided with a through hole 5. The two fixed frames 2 are connected at their ends without the through hole 5 by the connecting strap 3. The surface of the fixed frame 2 provided with the through hole 5 is configured as a circular arc surface. The circular arc surface can better conform to the patient's face and provide better patient comfort. The other end of the fixed frame 2 is rotatably connected to one end of the elastic strap 4. A locking unit is installed on the flat surface of the fixed frame 2 away from the circular arc surface. The tonometer 1 is mounted on the fixed frame 2 via the locking unit. Before use, the tonometer 1 is fixed to the corresponding fixed frame 2 of the eye to be measured via the locking unit. The fixed frame 2 is fixed to the patient's head via the elastic strap 4. The fixed frame 2 is adjusted to align with the patient's eye. At this point, the tonometer 1 and the eye are in a reasonable measurement position. In addition, the above mechanism replaces the method of the patient holding the tonometer 1 with the hand for measurement, ensuring the relative stability of the tonometer 1 and the eye during the test process, thereby making the measurement data more accurate.

[0022] refer to Figures 2 to 4 The locking unit includes a movable groove 6, a pressing plate 7, a spring 8, a positioning block 9, a support rod 10, a telescopic rod 11, a T-shaped slide groove 12 and a positioning groove 13. The mounting surface of the tonometer 1 in contact with the fixed frame 2 is symmetrically provided with an embedding groove 14 about the center of the plane. A plurality of movable grooves 6 are arranged in an array in the embedding groove 14. The telescopic rod 11 is slidably installed in the movable groove 6. The spring 8 is installed in the movable groove 6, and the two ends of the spring 8 are elastically supported by the telescopic rod 11 and the inner bottom wall of the movable groove 6 respectively. The embedding groove 14 The end of the telescopic rod 11 inside is connected to the pressing plate 7 corresponding to the embedding groove 14, and the support rod 10 is symmetrically installed on the mounting surface where the tonometer 1 contacts the fixed frame 2. The end of the support rod 10 away from the tonometer 1 is installed with a positioning block 9. A T-shaped slide groove 12 in the shape of the positioning block 9 and the support rod 10 is symmetrically provided with respect to the through hole 5 on the plane where the fixed frame 2 contacts the tonometer 1. An entry hole 16 is provided at one end of the T-shaped slide groove 12, and a positioning groove 13 is provided at the other end of the T-shaped slide groove 12.

[0023] When the tonometer 1 needs to be installed on the fixed frame 2, align the positioning block 9 with the entry hole 16, and then push the positioning block 9 into the bottom of the T-shaped slot 12. During this process, the pressing plate 7 will contact the fixed frame 2 and squeeze each other, and the telescopic rod 11 will squeeze the spring 8 to move closer to the spring 8, and the pressing plate 7 will be embedded in the embedding slot 14. Rotate the tonometer 1 or the fixed frame 2 so that the two produce relative rotation. At this time, the support rod 10 and the positioning block 9 move along the T-shaped slot 12. When the positioning block 9 slides to the end of the T-shaped slot 12 away from the entry hole 16, it stops. At this time, the positioning block 9 is aligned with the positioning slot 13. Release the pressure of the hand on the tonometer 1. The telescopic rod 11 will move in the direction away from the spring 8 under the action of the spring 8, thereby driving the pressing plate 7 to push the tonometer 1 in the direction away from the fixed frame 2 until the positioning block 9 is embedded in the positioning slot 13, forming the installation of the tonometer 1 on the fixed frame 2. When the tonometer 1 needs to be installed on another fixed frame 2, it is necessary to press the tonometer 1 so that the positioning block 9 disengages from the positioning groove 13, and then rotate it in the opposite direction so that the positioning block 9 disengages from the T-shaped slide groove 12, and then repeat the same action to install the tonometer 1 on another fixed frame 2.

[0024] An adjuster 15 for adjusting the length of the elastic band 4 is rotatably installed at one end of the fixed frame 2 away from the connecting band 3. One end of the elastic band 4 passes through the adjuster 15. The adjuster 15 can adjust the effective length of the elastic band 4 to adapt to different patients, thereby ensuring the stability of the fixed frame 2 while improving practicality.

[0025] The tonometer 1 is equipped with a Bluetooth device that can upload test data to a terminal, making it convenient for patients to view and store the data. Elastic pads are installed around the through-holes 5 on the curved surface of the fixed frame 2. These pads increase the contact area and reduce pressure, preventing the tension of the elastic band 4 from causing discomfort by squeezing the fixed frame 2 against the patient's eyes.

[0026] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of illustration and description. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials or characteristics described can be combined in an appropriate manner in any one or more embodiments or examples. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can make modifications, substitutions, variations and various different choices and changes to the embodiments without creative contribution as needed after reading this specification without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
