Description

Technical Field

[0001] The present invention relates to the technical field of neck circumference measurement, and particularly to a medical in-bed neck circumference measurement device. Background Art

[0002] A medical in-bed neck circumference measurement device is a medical device specifically designed to measure the neck circumference of bedridden patients. It combines the advantages of ergonomics and medical technology, ensuring the accuracy of measurement and the comfort of patients. The principle of laser neck circumference measurement is mainly based on laser ranging technology. A laser beam is emitted by a laser rangefinder (usually composed of a laser emitter and a camera) to the neck surface of the person being measured, and the camera receives the reflected light of the laser beam. When the laser rangefinder and the neck of the person being measured move synchronously, the coordinate values of several points at the same height on the neck can be calculated through computer algorithms based on information such as the light-receiving position, time interval, and optical axis angle, thereby obtaining the data of the neck surface and further calculating the neck circumference. Currently, during the use of laser neck circumference measurement devices by doctors, accurate measurement results can only be obtained when the human body remains relatively stationary. For people who have difficulty remaining stationary for a long time, such as patients, laser measurement may be difficult, resulting in inaccurate measurement and errors during laser measurement. Summary of the Invention

[0003] The purpose of the present invention is to provide a medical in-bed neck circumference measurement device. By driving the pillowcase assembly to move through the measurement component, the moving plate pushes the pillow on one side, causing the pillow on one side to be compressed, the two pillows to separate, leaving a gap, and the back of the neck to be exposed, which does not interfere with laser neck circumference measurement. Then, by moving the threaded rod of the clamping component inside the threaded sleeve, the two second clamping plates on both sides are driven to approach each other, fixing the patient's head to prevent the patient, who has difficulty remaining stationary for a long time, from moving their head, which may cause difficulties in laser measurement.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A medical in-bed neck circumference measurement device, including a pillowcase assembly, one side of the pillowcase assembly is fixedly connected to a measurement component, and clamping components are fixedly installed on both sides of the measurement component.

[0016] The present invention provides a medical in-bed neck circumference measuring device, including a pillowcase assembly 2, which assists doctors in measuring the neck circumference of patients. A measuring assembly 3 is fixedly connected to one side of the pillowcase assembly 2, and the measuring assembly 3 measures the neck circumference of patients. Clamping assemblies 4 are fixedly installed on both sides of the measuring assembly 3 to assist doctors in measuring the neck circumference of patients. Refer to Figures 1 to 4 As shown, the pillowcase assembly 2 includes a pillow 201, which assists patients in measuring the neck circumference. A fixed frame 202 is fixedly installed at the lower end of the pillow 201, and the fixed frame 202 is used to fixedly support the operation of the internal device. A first rotating rod 203 is installed inside the fixed frame 202, and the first rotating rod 203 rotates to transmit power. A gearbox 211 is fixedly connected to one side of the first rotating rod 203, and the gearbox 211 is used to transmit and drive the first rotating rod 203 to rotate. A first moving sleeve 204 is movably installed on the first rotating rod 203, and the first rotating rod 203 drives the first moving sleeve 204 to move. A moving plate 205 is fixedly installed on the first moving sleeve 204, and the moving plate 205 follows the first moving sleeve 204 to move. The moving plate 205 is used to push one side of the pillow 201, causing one side of the pillow 201 to be compressed, the two sides of the pillow 201 to separate, leaving a gap, and the back of the neck to be exposed, without interfering with the laser measurement of the neck circumference. Telescopic rods 207 are fixedly installed on both sides of the fixed frame 202. The telescopic rods 207 contract when pressed by the doctor. Fixed sleeves 208 are fixedly installed on one side of each telescopic rod 207 to support the operation of the internal device and move downward following the telescopic rods 207. First moving rods 209 are fixedly installed inside each fixed sleeve 208, and the first moving rods 209 move inside the fixed sleeves 208. First clamping plates 210 are fixedly installed on one side of each first moving rod 209, and the first clamping plates 210 follow the first moving rods 209 to move. When the gearbox 211 drives the first rotating rod 203 to rotate, the moving plate 205 moves on the first rotating rod 203 through the first moving sleeve 204, and the moving plate 205 pushes one side of the pillow 201, causing one side of the pillow 201 to be compressed, the two sides of the pillow 201 to separate, leaving a gap, and the back of the neck to be exposed, without interfering with the laser measurement of the neck circumference. At the same time, the doctor pushes the first moving rods 209 on both sides, and the first moving rods 209 move inside the fixed sleeves, causing the first clamping plates 210 on both sides to clamp the patient's hair. Then, the first moving rods 209 are pressed downward, causing the telescopic rods 207 to be contracted through the fixed sleeves 208, and the telescopic rods 207 contract to move the patient's hair away from the neck, preventing long-haired patients from having their neck circumference measured because the hair interferes with the laser measurement and it is difficult to obtain accurate measurement results.

[0017] Refer to Figures 4 to 6As shown in the figure, the measuring assembly 3 includes a motor 301. The motor 301 is the power source of the device, providing power output for the device. On one side of the motor 301, a second rotating rod 302 is fixedly installed. The motor 301 drives the second rotating rod 302 to rotate. One side of the second rotating rod 302 is connected to the gearbox 211. The power is output to the pillowcase assembly 2 through the gearbox 211 to provide power for the pillowcase assembly 2. A second moving sleeve 309 is movably installed on the second rotating rod 302. The second rotating rod 302 drives the second moving sleeve 309 to move. L-shaped moving rods 303 are fixedly installed on both sides of the second moving sleeve 309. The two L-shaped moving rods 303 move along with the second moving sleeve 309. U-shaped moving rods 304 are fixedly installed on both of the two L-shaped moving rods 303. Thus, the L-shaped moving rods 303 drive the U-shaped moving rods 304 to move. Second fixing blocks 305 are fixedly connected to one side of each U-shaped moving rod 304. The second fixing blocks 305 move along with the U-shaped moving rods 304 and fix the internal device. A laser instrument 306 is fixedly installed inside the second fixing blocks 305. The laser instrument 306 moves along with the U-shaped moving rods 304 through the second fixing blocks 305. When it moves to the patient's neck, the neck circumference is measured. When the motor 301 is started, the motor 301 drives the second rotating rod 302 to rotate. One side of the second rotating rod 302 is connected to the gearbox 211. The power is output to the pillowcase assembly 2 through the gearbox 211 to provide power for the pillowcase assembly 2. At the same time, the second rotating rod 302 drives the second moving sleeve 309 to move. The two L-shaped moving rods 303 move along with the second moving sleeve 309. Thus, the L-shaped moving rods 303 drive the U-shaped moving rods 304 to move. The laser instrument 306 moves along with the U-shaped moving rods 304 through the second fixing blocks 305. When it moves to the patient's neck, the neck circumference is measured; Refer to Figures 6 to 7 As shown in the figure, both clamping assemblies 4 on both sides include threaded sleeves 401, which are used to fix and provide a moving place for the internal device. Threaded rods 402 are installed inside the threaded sleeves 401. The threaded rods 402 move inside the threaded sleeves 401. Bearings 403 are fixedly installed on one side of each threaded rod 402. The bearings 403 ensure that when the external device operates, the internal device is stable and not affected. Second clamping plates 404 are installed on one side of each bearing 403. The second clamping plates 404 move along with the 402 to fix the patient's head. When the two clamping assemblies 4 move along with the measuring assembly 3, when the measuring assembly 3 moves to the patient's neck position, and the clamping assemblies 4 just move to the patient's head position, by the doctor rotating the threaded rods 402, the threaded rods 402 move inside the threaded sleeves 401, driving the two second clamping plates 404 to move closer to each other to fix the patient's head, preventing the patient who has difficulty remaining stationary for a long time from moving their head, resulting in difficulties in laser measurement.

[0018] In an alternative embodiment, a fixing frame is fixedly installed on the motor 301, and both sides of the fixing frame are fixedly installed on the bed legs. The fixing frame is used to fix the motor 301 and support the operation of the motor 301.

[0019] In an alternative embodiment, a first fixing block 206 is fixedly installed on one side of each of the two telescopic rods 207. One side of each first fixing block 206 is fixedly installed on both sides of the fixing frame 202. The first fixing block 206 is used for the telescopic rod 207 and to support the operation of the telescopic rod 207.

[0020] In an alternative embodiment, the gearbox 211 includes a first bevel gear 2111. A second bevel gear 2112 is rotatably connected to one side of the first bevel gear 2111. A connecting rod 2113 is fixedly installed on the second bevel gear 2112. When the motor 301 is started, the motor 301 drives the second rotating rod 302 to rotate. One side of the second rotating rod 302 drives the first bevel gear 2111 to rotate. The first bevel gear 2111 meshes with the second bevel gear 2112. The first bevel gear 2111 drives the second bevel gear 2112 to rotate. The second bevel gear 2112 transmits power through the connecting rod 2113.

[0021] In an alternative embodiment, a second bevel gear 2112 is also fixedly installed on one side of the connecting rod 2113. A third bevel gear 2114 is rotatably connected to one side of the second bevel gear 2112. When the motor 301 is started, the motor 301 drives the second rotating rod 302 to rotate. One side of the second rotating rod 302 drives the first bevel gear 2111 to rotate. The first bevel gear 2111 meshes with the second bevel gear 2112. The first bevel gear 2111 drives the second bevel gear 2112 to rotate. The second bevel gear 2112 transmits power through the connecting rod 2113. The power is transmitted to the second bevel gear 2112 which is also fixedly installed on one side of the connecting rod 2113. The second bevel gear 2112 rotates. The second bevel gear 2112 meshes with the third bevel gear 2114. The second bevel gear 2112 drives the third bevel gear 2114 to rotate. The third bevel gear 2114 drives the first rotating rod 203 to rotate.

[0022] In an alternative embodiment, sliding grooves 307 are slidably installed inside both U-shaped moving rods 304. Sliders 308 are slidably installed inside the sliding grooves 307. When the sliders 308 slide, they drive the sliding grooves 307 to slide together. When the two sliding grooves 307 slide to both sides of the second fixing block 305, they squeeze the second fixing block 305, so that the second fixing block 305 clamps the laser instrument 306, assisting in fixing the second fixing block 305 to fix the laser instrument 306. When the two sliding grooves 307 slide to both sides of the second fixing block 305, the two sliding grooves 307 stop moving, and the sliders 308 will slide alone inside the sliding grooves 307.

[0023] In an alternative embodiment, fixing blocks are provided on one side of each of the two side sliders 308, and the clamping assemblies 4 are fixedly mounted on the fixing blocks. Since the head sizes and heights of each patient are different, the doctor can push the clamping assemblies 4 upward to drive the sliders 308 to slide together in the sliding grooves 307. The sliding grooves 307 also slide along with the sliders 308. When the two side sliding grooves 307 slide to both sides of the second fixing block 305, they squeeze the second fixing block 305, so that the second fixing block 305 clamps the laser instrument 306, assisting in fixing the laser instrument 306 by the second fixing block 305. When the two side sliding grooves 307 slide to both sides of the second fixing block 305, the two side sliding grooves 307 stop moving, and the sliders 308 will slide alone in the sliding grooves 307, so as not to affect the upward movement of the clamping assemblies 4.

[0024] In an alternative embodiment, handles are provided on the other sides of the two side threaded rods 402, and handles are also provided on the other sides of the two first moving rods 209. The handles facilitate the doctor to operate the threaded rods 402 and the first moving rods 209.

[0025] Working principle: When the motor 301 is started, the motor 301 drives the second rotating rod 302 to rotate. One side of the second rotating rod 302 is connected to the gearbox 211, and power is output to the pillow assembly 2 through the gearbox 211 to provide power for the pillow assembly 2. The moving plate 205 moves on the first rotating rod 203 through the first moving sleeve 204. The moving plate 205 pushes the pillow 201 on one side, causing the pillow 201 on one side to be compressed, separating the two side pillows 201 and leaving a gap, exposing the back of the neck, which does not prevent laser measurement of the neck circumference. At the same time, the doctor pushes the two first moving rods 209. The first moving rods 209 move inside the fixed sleeves, so as to drive the two first clamping plates 210 to clamp the patient's hair. Then, the first moving rods 209 are pressed downward, so as to be transmitted to the telescopic rods 207 through the fixed sleeves 208, and the telescopic rods 207 contract, moving the patient's hair away from the neck, preventing long-haired patients from measuring the neck circumference, which may be hindered by the hair and difficult to obtain accurate measurement results; Meanwhile, the second rotating rod 302 drives the second moving sleeve 309 to move, and the two L-shaped moving rods 303 follow the second moving sleeve 309 to move. Thus, the L-shaped moving rods 303 drive the U-shaped moving rod 304 to move, and the laser instrument 306 moves along with the U-shaped moving rod 304 through the second fixing block 305. When it moves to the patient's neck, the neck circumference is measured. When the two clamping assemblies 4 follow the measuring assembly 3 to move, and the measuring assembly 3 moves to the patient's neck position while the clamping assemblies 4 just move to the patient's head position, by the doctor rotating the threaded rod 402, the threaded rod 402 moves inside the threaded sleeve 401, driving the two second clamping plates 404 to approach each other to fix the patient's head, preventing the patient who has difficulty in remaining stationary for a long time from moving their head, which may cause difficulties in laser measurement. Since the head sizes and heights of each patient are different, the doctor can push the clamping assembly 4 upward to drive the slider 308 to slide in the chute 307 together through the fixing block, and the chute 307 also slides along with the slider 308. When the two chutes 307 slide to both sides of the second fixing block 305 and squeeze the second fixing block 305, the second fixing block 305 clamps the laser instrument 306 to assist in fixing the laser instrument 306 by the second fixing block 305. When the two chutes 307 slide to both sides of the second fixing block 305, the two chutes 307 stop moving, and the slider 308 will slide alone in the chute 307, thus not affecting the upward movement of the clamping assembly 4.
