Technical Field

[0001] This invention relates to the field of VR device technology, specifically to a VR device and method for patient pain assessment. Background Technology

[0002] Virtual reality is a computer technology that uses head-mounted goggles with a screen in front of the wearer's eyes and optionally speakers or headphones to provide a realistic and interactive user experience, simulating the user's presence in a virtual environment. Tracking the movement of virtual reality (VR) headsets allows users to "look around" in a three-dimensional virtual world.

[0003] Virtual reality is currently being used to some extent in the medical field, primarily for simulation-based training of medical professionals. It is speculated that virtual reality may be able to assist with pain assessment for specific patients or be used in behavioral therapy treatments.

[0004] Existing VR devices for patient pain assessment are equipped with wearing brackets to facilitate patient wearing. However, the wearing brackets are usually fixedly connected to the VR device, which makes it difficult for some patients to wear the brackets properly to fit their heads, resulting in discomfort and making it inconvenient to conduct pain assessments for different patients. Summary of the Invention

[0016] Preferably, the adjusting housing has a spring groove, a spring block is slidably disposed in the spring groove, the adjusting teeth are rotatably disposed on the spring block, and a pop-out component is disposed in the adjusting housing for popping out the spring block.

[0017] Preferably, the pop-out component includes a top holding groove, a top holding spring, and a limiting member. The top holding groove is formed inside the adjusting housing. One end of the top holding spring is connected to the pop-out block, and the other end is limited by the top holding groove. The limiting member is used to limit the pop-out block.

[0018] Preferably, the limiting component includes an adjusting cavity, a limiting block, a through groove, a limiting rod, and a limiting slot. The adjusting cavity is opened inside the adjusting housing, the limiting block is slidably disposed inside the adjusting cavity, the through groove is opened inside the adjusting housing and connects the spring groove and the adjusting cavity, the limiting rod is disposed at the position of the spring corresponding to the through groove and can extend into the adjusting cavity, the limiting rod has an "L" shaped structure, the limiting slot is opened on the limiting block at the position of the limiting rod, and an adjusting spring is provided between the limiting block and the adjusting cavity.

[0019] The limiting groove includes a pressing area and a locking area. The pressing area has a right-angled trapezoidal structure, and the locking area has a rectangular structure. The pressing area is located close to the through groove. A limiting slide groove is opened in the adjusting cavity. A limiting slider is set at the corresponding position of the limiting slide groove of the limiting block.

The fourth bevel gear meshes with the first bevel gear. A third bevel gear is arranged at the end of the rotating rod extending out of the spring block, and a second bevel gear is arranged at the position corresponding to the third bevel gear on the rotating shaft. When the spring block extends out of the adjusting housing, the third bevel gear meshes with the second bevel gear.

[0022] A method for using a VR device for patient pain assessment includes the following steps:

[0023] Slow adjustment: By moving the adjustment pawl, the adjustment pawl drives the first transmission gear to rotate, the first transmission gear drives the shaft to rotate, which in turn drives the second transmission gear to rotate. The second transmission gear and the third transmission gear work together to drive the lead screw to rotate. Since the adjustment block is screwed to the lead screw and the guide groove guides and limits the adjustment block, the adjustment block is moved up or down, thereby adjusting the distance between the wearing bracket and the VR device body to fit the head of different patients.

[0024] Quick Adjustment: By pressing the adjustment button, the button moves the pressing rod. The pressing rod contacts the reset groove, causing the limiting block to move towards the adjusting spring and compressing the adjusting spring. At this time, the limiting rod moves from the locking area of ​​the limiting groove to the holding area until the limiting rod enters the holding area of ​​the limiting groove. The holding spring holds the spring block, causing the spring block to extend out of the adjustment housing, thereby causing the adjusting tooth and the first transmission gear to disengage. At this time, the adjusting tooth is fully extended outside the adjustment housing, making it easy to turn the adjusting tooth. The spring block extends and drives the rotating rod to move, thereby causing the third bevel gear and the second bevel gear to mesh. At this time, the adjusting tooth is rotated, and the adjusting tooth drives the first bevel gear to rotate through the connecting rod. The first bevel gear and the fourth bevel gear work together to drive the rotating rod to rotate, thereby driving the rotating shaft to rotate through the third bevel gear and the second bevel gear to rotate. The second transmission gear and the third transmission gear work together to drive the lead screw to rotate. The adjusting block is screwed to the lead screw, and the guide groove guides and limits the adjusting block, thereby causing the adjusting block to move up or down, realizing quick adjustment of the distance between the wearing bracket and the VR device body to adapt to the heads of different patients.

[0025] Wearing assessment: By pressing the spring block, the spring block moves the limiting rod towards the limiting groove until the limiting rod contacts the pressing area of ​​the limiting groove, which in turn moves the limiting block towards the adjusting spring until the limiting rod enters the locking area of ​​the limiting groove. At this time, the adjusting spring holds the limiting block back to its original position, thereby limiting the limiting rod and the spring block, so that the spring block is retracted into the adjusting housing. The adjusting teeth mesh with the first transmission gear. Then, the wearing bracket is worn on the head for easy assessment.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] This invention uses an adjusting component to move the adjusting block up or down, which in turn moves the wearing bracket up or down, adjusting the distance between the wearing bracket and the VR device body. This allows it to fit the heads of different patients, ensuring that patients do not experience discomfort when wearing the device during assessment, thus facilitating the assessment process.

[0028] By adjusting the adjustment teeth, the adjustment teeth drive the first transmission gear to rotate, the first transmission gear drives the rotating shaft to rotate, which in turn drives the second transmission gear to rotate. The second transmission gear and the third transmission gear work together to drive the lead screw to rotate. Since the adjustment block is screwed to the lead screw and the guide groove guides and limits the adjustment block, the adjustment block is moved up or down, thereby adjusting the distance between the wearing bracket and the VR device body to fit the head of different patients.

[0029] By pressing the adjustment button, the button moves the pressing rod. The pressing rod contacts the reset groove, causing the limiting block to move towards the adjusting spring and compress the adjusting spring. At this time, the limiting rod moves from the locking area of ​​the limiting groove to the holding area until the limiting rod enters the holding area of ​​the limiting groove. The holding spring holds the spring block, causing the spring block to extend out of the adjustment housing, thereby causing the adjusting tooth and the first transmission gear to disengage. At this time, the adjusting tooth is fully extended outside the adjustment housing, making it easy to turn the adjusting tooth. The spring block extends and drives the rotating rod to move, thereby causing the third bevel gear and the second bevel gear to mesh. At this time, the adjusting tooth is rotated, and the adjusting tooth drives the first bevel gear to rotate through the connecting rod. The first bevel gear and the fourth bevel gear work together to drive the rotating rod to rotate, thereby driving the rotating shaft to rotate through the third bevel gear and the second bevel gear to rotate. The second transmission gear and the third transmission gear work together to drive the lead screw to rotate. The adjusting block is screwed to the lead screw, and the guide groove guides and limits the adjusting block, thereby causing the adjusting block to move up or down, realizing the quick adjustment of the distance between the wearing bracket and the VR device body to adapt to the heads of different patients.

[0030] By pressing the spring block, the spring block moves the limiting rod toward the limiting groove until the limiting rod contacts the pressing area of ​​the limiting groove, which in turn moves the limiting block toward the adjusting spring until the limiting rod enters the locking area of ​​the limiting groove. At this time, the adjusting spring holds the limiting block back to its original position, thereby limiting the limiting rod and the spring block, so that the spring block is retracted into the adjusting housing. The adjusting teeth mesh with the first transmission gear, and then the wearing bracket is worn on the head for easy evaluation. Attached Figure Description

This allows it to fit the heads of different patients, ensuring that patients do not experience discomfort when wearing it during the assessment, thus facilitating the assessment. Example

[0046] like Figure 2-7 As shown, the VR device and method for patient pain assessment disclosed in Embodiment 2 of the present invention have a structure that is basically the same as that in Embodiment 1. The difference is that it is easier to adjust the position of the wearing bracket 2. The adjustment component includes a movable cavity 9, a guide groove 10, a lead screw 8, a driving component, and a transmission component. The movable cavity 9 is opened in the adjustment housing 3.

[0047] The transmission components include a rotating shaft 29, a second transmission gear 30, and a third transmission gear 31. The rotating shaft 29 is rotatably disposed within the adjusting housing 3 and passes through the first transmission gear 28. The second transmission gear 30 is disposed at the bottom of the rotating shaft 29, and the third transmission gear 31 is disposed at the position of the lead screw 8 corresponding to the second transmission gear 30, and the second transmission gear 30 and the third transmission gear 31 mesh. A spring groove 12 is provided on the adjusting housing 3, and a spring block 6 is slidably disposed within the spring groove 12. An adjusting paddle 5 is rotatably disposed on the spring block 6.

The pop-out component includes a top holding groove 15, a top holding spring 16, and a limiting component. The top holding groove 15 is provided within the adjusting housing 3. One end of the top holding spring 16 is connected to the spring block 6, and the other end is limited by the top holding groove 15. The limiting component is used to limit the spring block 6.

[0048] The limiting component includes an adjusting cavity 17, a limiting block 20, a through groove 22, a limiting rod 21, and a limiting slot 27. The adjusting cavity 17 is located within the adjusting housing 3. The limiting block 20 is slidably disposed within the adjusting cavity 17. The through groove 22 is located within the adjusting housing 3 and connects the spring groove 12 and the adjusting cavity 17. The limiting rod 21 is positioned at the corresponding position of the through groove 22 on the spring block 6 and can extend into the adjusting cavity 17. The limiting rod 21 has an "L"-shaped structure. The limiting slot 27 is located on the limiting block 20 at the corresponding position of the limiting rod 21. The limiting block 20 and the adjusting cavity 17... An adjusting spring 25 is provided between the two, with one end of the adjusting spring 25 connected to the adjusting cavity 17 and the other end connected to the limiting block 20. The limiting groove 27 includes a pressing area and a locking area. The pressing area has a right-angled trapezoidal structure, and the locking area has a rectangular structure. The pressing area is located close to the through groove 22. A limiting slide groove 18 is opened in the adjusting cavity 17. A limiting slider 19 is provided at the corresponding position of the limiting slide groove 18 on the limiting block 20. The limiting slider 19 is slidably disposed in the limiting slide groove 18, and the longitudinal section of the limiting slide groove 18 and the limiting slider 19 has a "T" shaped structure.

[0049] An adjustment housing 3 has a pressing groove 7, and an adjustment button 4 is slidably disposed within the pressing groove 7. A pressing spring 24 is disposed between the adjustment button 4 and the pressing groove 7, used to push one end of the adjustment button 4 out of the adjustment housing 3. A pressing rod 23 is connected to the side of the adjustment button 4 near the pressing spring 24. One end of the pressing rod 23 extends into the adjustment cavity 17. The pressing rod 23 has an "L"-shaped structure. A reset groove 26 is provided at the position of the limiting block 20 corresponding to the pressing rod 23. The reset groove 26 has a right-angled trapezoidal shape, and the depth of the reset groove 26 is equal to the depth of the limiting groove 27. A spring block 6 is rotatably disposed within the spring block 6. The top of the connecting rod 13 is connected to the adjusting tooth 5, and the bottom of the connecting rod 13 is connected to the first bevel gear 14. A rotating rod 33 is rotatably installed inside the spring block 6. One end of the rotating rod 33 extends out of the spring block 6, and a fourth bevel gear 35 is installed at the position of the rotating rod 33 corresponding to the position of the first bevel gear 14. The fourth bevel gear 35 meshes with the first bevel gear 14. A third bevel gear 34 is installed at the end of the rotating rod 33 extending out of the spring block 6, and a second bevel gear 32 is installed at the position of the rotating shaft 29 corresponding to the position of the third bevel gear 34. When the spring block 6 extends out of the adjusting housing 3, the third bevel gear 34 meshes with the second bevel gear 32.

[0050] By adjusting the adjustment tooth 5, the adjustment tooth 5 drives the first transmission gear 28 to rotate, the first transmission gear 28 drives the rotating shaft 29 to rotate, and then drives the second transmission gear 30 to rotate. The second transmission gear 30 and the third transmission gear 31 cooperate to drive the lead screw 8 to rotate. Since the adjustment block 11 is screwed to the lead screw 8 and the guide groove 10 guides and limits the adjustment block 11, the adjustment block 11 is driven to move up or down, thereby adjusting the distance between the wearing bracket 2 and the VR device body 1 to fit the head of different patients.

[0051] By pressing the adjustment button 4, the adjustment button 4 drives the pressing rod 23 to move. The pressing rod 23 contacts the reset groove 26, causing the limiting block 20 to move toward the adjusting spring 25 and compress the adjusting spring 25. At this time, the limiting rod 21 moves from the locking area of ​​the limiting groove 27 to the holding area until the limiting rod 21 enters the holding area of ​​the limiting groove 27. The holding spring 16 holds the spring block 6, causing the spring block 6 to extend out of the adjustment housing 3, thereby causing the adjusting tooth 5 and the first transmission gear 28 to disengage. At this time, the adjusting tooth 5 extends completely out of the adjustment housing 3, making it easy to turn the adjusting tooth 5. The spring block 6 extends and drives the rotating rod 33 to move, thereby causing the third bevel gear 34 and the second bevel gear to move. When wheel 32 is engaged, the adjusting tooth 5 is rotated. The adjusting tooth 5 drives the first bevel gear 14 to rotate through the connecting rod 13. The first bevel gear 14 and the fourth bevel gear 35 cooperate to drive the rotating rod 33 to rotate. Then, through the cooperation of the third bevel gear 34 and the second bevel gear 32, the rotating shaft 29 is driven to rotate, which drives the second transmission gear 30 to rotate. The second transmission gear 30 and the third transmission gear 31 cooperate to drive the lead screw 8 to rotate. The adjusting block 11 is screwed to the lead screw 8, and the guide groove 10 guides and limits the adjusting block 11, thereby driving the adjusting block 11 to move up or down, so as to quickly adjust the distance between the wearing bracket 2 and the VR device body 1 to fit the head of different patients.

[0052] By pressing the spring block 6, the spring block 6 causes the limiting rod 21 to move toward the limiting groove 27 until the limiting rod 21 contacts the pressing area of ​​the limiting groove 27, thereby causing the limiting block 20 to move toward the adjusting spring 25 until the limiting rod 21 enters the locking area of ​​the limiting groove 27. At this time, the adjusting spring 25 pushes the limiting block 20 back to its original position, thereby limiting the limiting rod 21 and the spring block 6, so that the spring block 6 is retracted into the adjusting housing 3, the adjusting tooth 5 meshes with the first transmission gear 28, and then the wearing bracket 2 is worn on the head for easy evaluation.

[0053] Specifically, this solution is as follows: by adjusting the adjustment tooth 5, the adjustment tooth 5 drives the first transmission gear 28 to rotate, the first transmission gear 28 drives the rotating shaft 29 to rotate, and then drives the second transmission gear 30 to rotate. The second transmission gear 30 and the third transmission gear 31 cooperate to drive the lead screw 8 to rotate. Since the adjustment block 11 is screwed to the lead screw 8, and the guide groove 10 guides and limits the adjustment block 11, the adjustment block 11 is driven to move up or down, thereby adjusting the distance between the wearing bracket 2 and the VR device body 1 to fit the heads of different patients.

[0054] By pressing the adjustment button 4, the adjustment button 4 drives the pressing rod 23 to move. The pressing rod 23 contacts the reset groove 26, causing the limiting block 20 to move toward the adjusting spring 25 and compress the adjusting spring 25. At this time, the limiting rod 21 moves from the locking area of ​​the limiting groove 27 to the holding area until the limiting rod 21 enters the holding area of ​​the limiting groove 27. The holding spring 16 holds the spring block 6, causing the spring block 6 to extend out of the adjustment housing 3, thereby causing the adjusting tooth 5 and the first transmission gear 28 to disengage. At this time, the adjusting tooth 5 extends completely out of the adjustment housing 3, making it easy to turn the adjusting tooth 5. The spring block 6 extends and drives the rotating rod 33 to move, thereby causing the third bevel gear 34 and the second bevel gear to move. When wheel 32 is engaged, the adjusting tooth 5 is rotated. The adjusting tooth 5 drives the first bevel gear 14 to rotate through the connecting rod 13. The first bevel gear 14 and the fourth bevel gear 35 cooperate to drive the rotating rod 33 to rotate. Then, through the cooperation of the third bevel gear 34 and the second bevel gear 32, the rotating shaft 29 is driven to rotate, which drives the second transmission gear 30 to rotate. The second transmission gear 30 and the third transmission gear 31 cooperate to drive the lead screw 8 to rotate. The adjusting block 11 is screwed to the lead screw 8, and the guide groove 10 guides and limits the adjusting block 11, thereby driving the adjusting block 11 to move up or down, so as to quickly adjust the distance between the wearing bracket 2 and the VR device body 1 to fit the head of different patients.

[0055] By pressing the spring block 6, the spring block 6 causes the limiting rod 21 to move toward the limiting groove 27 until the limiting rod 21 contacts the pressing area of ​​the limiting groove 27, thereby causing the limiting block 20 to move toward the adjusting spring 25 until the limiting rod 21 enters the locking area of ​​the limiting groove 27. At this time, the adjusting spring 25 pushes the limiting block 20 back to its original position, thereby limiting the limiting rod 21 and the spring block 6, so that the spring block 6 is retracted into the adjusting housing 3, the adjusting tooth 5 meshes with the first transmission gear 28, and then the wearing bracket 2 is worn on the head for easy evaluation.

6. The VR device for patient pain assessment according to claim 5, characterized in that, A connecting rod is rotatably mounted inside the spring block. The top of the connecting rod is connected to the adjusting gear, and the bottom of the connecting rod is connected to the first bevel gear. A rotating rod is rotatably mounted inside the spring block. One end of the rotating rod extends out of the spring block, and a fourth bevel gear is mounted at the position corresponding to the first bevel gear. The fourth bevel gear meshes with the first bevel gear. A third bevel gear is mounted at the end of the rotating rod extending out of the spring block, and a second bevel gear is mounted at the position corresponding to the third bevel gear on the rotating shaft. When the spring block extends out of the adjusting housing, the third bevel gear meshes with the second bevel gear.

7. A method of using a VR device for patient pain assessment, comprising the VR device for patient pain assessment as described in any one of claims 1-6, the method comprising the following steps: Slow adjustment: By moving the adjustment pawl, the adjustment pawl drives the first transmission gear to rotate, the first transmission gear drives the shaft to rotate, which in turn drives the second transmission gear to rotate. The second transmission gear and the third transmission gear work together to drive the lead screw to rotate. Since the adjustment block is screwed to the lead screw and the guide groove guides and limits the adjustment block, the adjustment block is moved up or down, thereby adjusting the distance between the wearing bracket and the VR device body to fit the head of different patients. Quick Adjustment: By pressing the adjustment button, the button moves the pressing rod. The pressing rod contacts the reset groove, causing the limiting block to move towards the adjusting spring and compressing the adjusting spring. At this time, the limiting rod moves from the locking area of ​​the limiting groove to the holding area until the limiting rod enters the holding area of ​​the limiting groove. The holding spring holds the spring block, causing the spring block to extend out of the adjustment housing, thereby causing the adjusting tooth and the first transmission gear to disengage. At this time, the adjusting tooth is fully extended outside the adjustment housing, making it easy to turn the adjusting tooth. The spring block extends and drives the rotating rod to move, thereby causing the third bevel gear and the second bevel gear to mesh. At this time, the adjusting tooth is rotated, and the adjusting tooth drives the first bevel gear to rotate through the connecting rod. The first bevel gear and the fourth bevel gear work together to drive the rotating rod to rotate, thereby driving the rotating shaft to rotate through the third bevel gear and the second bevel gear to rotate. The second transmission gear and the third transmission gear work together to drive the lead screw to rotate. The adjusting block is screwed to the lead screw, and the guide groove guides and limits the adjusting block, thereby causing the adjusting block to move up or down, realizing quick adjustment of the distance between the wearing bracket and the VR device body to adapt to the heads of different patients. Wearing assessment: By pressing the spring block, the spring block moves the limiting rod towards the limiting groove until the limiting rod contacts the pressing area of ​​the limiting groove, which in turn moves the limiting block towards the adjusting spring until the limiting rod enters the locking area of ​​the limiting groove. At this time, the adjusting spring holds the limiting block back to its original position, thereby limiting the limiting rod and the spring block, so that the spring block is retracted into the adjusting housing. The adjusting teeth mesh with the first transmission gear. Then, the wearing bracket is worn on the head for easy assessment.
