DETAILED DESCRIPTION
[0039] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.
[0040] Example 1
[0041] See also Figure 1 and Figure 13-14 As shown, this embodiment provides a head-mounted mental patient detection device, including a base, a support column 18 installed on the base, and a mounting ring 1. The mounting ring 1 is installed on the support column 18 by bolts, and the two are connected by bolts. The mounting ring 1 can be removed from the support column 18, which is convenient for replacing or cleaning and disinfecting the mounting ring.
[0042] Preferably, Figure 8 As shown, a connecting ring 20 is fixedly installed on the side of the mounting ring 1, a rotating ring 19 is rotatably installed on the end of the support column 18, a stud is fixedly installed on the bottom of the rotating ring 19, and the stud is connected to the connecting ring 20 through a thread. By rotating the rotating ring 19, the stud and the connecting ring 20 can be connected together, which is convenient for the installation of the mounting ring 1.
[0043] A retaining ring 181 is fixedly mounted on the end of the support column 18 to support the rotating ring 19 and prevent the rotating ring 19 from falling off the support column 18 .
[0044] Of course, a connecting plate 4 can be fixedly installed on one side of the bottom of the mounting ring 1. The connecting plate 4 has bolt holes. The connecting plate 4 can be fixed to the seat by bolts, and the head can also be tested. The mounting ring can also be fixed on the bed. Since the mounting ring is provided with a groove 2, even if the mounting ring 1 is placed at 90 degrees, the mounting part will still be placed in the groove 2 and will not fall off or tilt. The mounting ring 1 has various mounting methods, which increases the installation function.
[0045] An annular groove 2 is formed at the upper end of the mounting ring 1 , and a support plate 22 is installed inside the groove 2 . The support plate 22 slides up and down inside the groove 2 , so as to adjust the depth of the groove 2 .
[0046] A through hole is provided on the outside of the groove 2, and a fixing block 3 is fixedly installed at the upper and lower parts of the through hole. A bolt 31 is rotatably installed between the two fixing blocks 3. The fixing block 3 serves as the mounting part of the bolt 31. The bottom and top of the bolt 31 are connected to the fixing block 3, and the fixing block 3 extends from the top of the bolt 31, which is convenient for rotating the bolt 31. A convex plate 21 extending from a through hole is fixedly installed on the outside of the support plate 22. The bolt 31 penetrates the convex plate 21 and is connected to the convex plate 21 by a thread. A mounting part is placed on the upper part of the groove 2. The bolt 31 is rotated, and the support plate 22 can slide up and down under the action of the thread, thereby changing the depth of the groove 2, and the mounting part can be slid up and down with it, so as to adjust the height of the mounting part and change the distance between the detection device and the head.
[0047] In this embodiment, the mounting portion is configured as a hollow hemisphere 7. When testing the human brain, the hemisphere 7 can be placed on the upper part of the brain and in contact with the brain. A plurality of mounting holes 9 are provided on the hemisphere 7. The mounting holes 9 are plugged with detection heads. The inside of the mounting holes 9 does not need to be plugged with detection heads. The required detection heads can be inserted into the mounting holes 9 according to the use requirements.
[0048] When plugging in the detection head, in order to facilitate the replacement and fixation of the detection head, such as Figure 1As shown, a contact ring 10 is inserted into the mounting hole 9. The contact ring 10 is a C-shaped structure and is made of sponge or rubber material. The contact ring 10 can be relatively easily compressed and deformed, and can be conveniently inserted into the mounting hole 9. Moreover, when installing the detection head, the detection head can be placed into the contact ring 10 from one side of the contact ring 10, and then the contact ring 10 and the detection head are inserted into the mounting hole 9 together. Since the contact ring 10 can be compressed, it can be relatively conveniently inserted into the mounting hole 9, and the contact ring 10 is squeezed to fix the detection head.
[0049] In this embodiment, in order to facilitate the removal of the contact ring 10 from the mounting hole 9, the height of the contact ring 10 is greater than the depth of the mounting hole 9. When the contact ring 10 is inserted into the mounting hole 9, the upper part of the contact ring 10 extends out from the mounting hole 9, and the contact ring 10 can be removed more conveniently.
[0050] In addition, when the detection head is not installed in the mounting hole 9, the contact ring 10 is inserted into the mounting hole 9, so that the mounting hole 9 can be in a closed state, which has a dust-proof effect.
[0051] A support bar 8 is fixedly installed on the outer side of the hemisphere 7. The support bar 8 serves as the skeleton of the hemisphere and supports the hemisphere 7. Figure 5-6 As shown, the inner wall of the hemisphere 7 is installed with a sponge pad 6 through a Velcro 5. The sponge pad 6 is located between the brain and the hemisphere 7. The sponge pad 6 is relatively soft and can improve the comfort of the user. The use of the Velcro 5 also facilitates the replacement of the sponge pad 6.
[0052] In this embodiment, the sponge pad 6 can be a block structure, placed on the top of the Velcro 5 and the bottom edge of the Velcro 5.
[0053] The sponge pad 6 can also be a strip structure, directly attached to the entire Velcro 5.
[0054] The Velcro 5 is arranged in a cross shape. In this embodiment, the fur surface hemispheres 7 of the Velcro 5 are bonded together, and the hook surface of the Velcro 5 is sewn or bonded to the sponge pad 6. Since the fur surface is relatively smooth, it will not affect the user when used.
[0055] Moreover, by replacing the sponge pad 6 with different thicknesses, the contact distance between the sponge pad 6 and the brain can be changed, and it can be suitable for heads of different sizes, thereby preventing the hemisphere 7 from shaking with the brain during use, and improving the accuracy of detection.
[0056] In this embodiment, the hemisphere 7 can also be removed from the groove 2 and worn directly on the human head, so a fixing belt for wearing is provided at the lower part of the hemisphere 7. When the hemisphere 7 is worn on the head, the fixing belt can be placed at the chin to fix the hemisphere 7 to the head. This wearing method is more flexible and is not restricted by the support column 18. People can wear it while lying on the bed, whether lying flat or lying at an angle, sitting or standing. They can even walk around in a small local area in the room while wearing it to detect the condition of the brain in motion.
[0057] In this embodiment, if Fig.10 As shown, in order to better protect the hemisphere 7 and the circuit of the detection head, a shell 11 is further provided on the outside of the hemisphere 7, and the shell directly covers the outside of the hemisphere 7, placing the outside of the detection head and the circuit of the detection head between the shell 11 and the hemisphere 7, thereby playing a protective role. In this state, the support bar 8 supports the shell 11, so that there is enough gap between the shell 11 and the hemisphere 7, so as to avoid the situation where the shell 11 directly contacts the hemisphere 7 and causes the detection head and the circuit to be squeezed.
[0058] A limit block protruding upward is provided at the top intersection of the support bars 8, and a limit groove matching the limit block is provided at the top of the shell 11. The limit block and the limit groove limit and fix the shell 11 to prevent the shell 11 from rotating above the hemisphere 7, and a bolt hole is provided in the middle of the limit block. The shell 11 and the hemisphere 7 are installed by bolts 12. The nut diameter of the bolt is larger than the width of the limit block. When the shell 11 and the hemisphere 7 are connected together, the bolt is located at the upper part of the shell 11, pressing the shell and the hemisphere 7 tightly, thereby fixing the two.
[0059] The limiting block and the limiting groove may be in a straight or cross shape, or in other shapes, as long as the housing 11 and the hemisphere 7 can be fixed.
[0060] In a further embodiment, Figure 2-4 As shown, the mounting portion further comprises at least two support rings 15, between which a column 16 is fixedly mounted; a cylindrical frame structure is formed between the support rings 15 and the column 16. The hemisphere 7 can be directly mounted in the cylindrical frame.
[0061] There are four columns 16 and support bars 8, which are arranged in a circular row, with adjacent structures arranged at 90 degrees. A slide groove 163 matching the support bar 8 is provided on the inner side of the bottom of the column 16. The hemisphere 7 is placed into it from the bottom of the cylindrical frame, and when placed, the support bar 8 slides in the slide groove 163. The clamping connection between the slide groove 163 and the support bar 8 connects and positions the hemisphere and the cylindrical frame, preventing the hemisphere from shaking in the cylindrical frame.
[0062] The upper side wall of the column 16 is provided with a snap-fitting groove 162, and a rotating plate 161 is rotatably mounted at the bottom of the snap-fitting groove 162. Bolt holes are provided on the rotating plate 161, the slide groove 163 and the support bar 8. When the hemisphere 7 is installed inside the cylindrical frame, the rotating plate 161 rotates toward the support bar 8, so that the two fit together, and the rotating plate 161 and the support bar are installed together by bolts. Similarly, the slide groove 163 is connected to the support bar 8 by bolts, and the hemisphere 7 and the cylindrical frame can be installed.
[0063] The cylindrical frame supports the hemisphere 7 , and the upright column 16 and the support ring 15 are located outside the hemisphere 7 , which protect the hemisphere 7 and the detection head installed on the hemisphere 7 .
[0064] A connecting ring 20 is fixedly mounted on the side of the cylindrical frame, and the connecting ring can be directly connected to the support column 18. A connecting ring 20 can also be provided on one side of the hemisphere 7 or the housing 11, such as Figure 7-9 shown.
[0065] Example 2
[0066] See also Figure 11-12 and 15, the mounting portion includes at least two support rings 15, between which a column 16 is fixedly mounted, the support rings 15 and the column 16 form a cylindrical frame structure, which is used as a mounting frame for mounting a detection device, which is some slightly larger equipment;
[0067] A bearing seat is installed at the upper end of the mounting portion by bolts, and the bearing seat includes a fixing plate 13 and an extension seat 14. The extension seat 14 is a cavity structure with an opening at the top, and the detection device can be directly placed in the cavity. An opening is also provided at the bottom of the extension seat 14. The diameter of the opening is smaller than the diameter of the cavity to prevent the detection device from falling from the cavity. In addition, the opening can make the working part of the detection device directly face the head to reduce obstruction.
[0068] In a further embodiment, a sliding groove is opened on the side wall of the extension seat 14, and a clamping strip 17 is installed inside the sliding groove. The clamping strip 17 can slide up and down inside the sliding groove. A spring 182 is installed between the bottom of the clamping strip 17 and the bottom of the sliding groove. The spring 182 always provides elastic force to the clamping strip 17. When the detection device is installed in the cavity, the clamping strip 17 is located at the upper part of the detection device and presses the detection device to prevent the detection device from shaking during use.
[0069] When installing the detection device, it is only necessary to slide the pressing strip 17 upwards so that the pressing strip 17 moves upwards and extends out of the cavity. A certain space will be left between the cavity and the pressing strip 17, and the detection device can be directly placed therein.
[0070] In this embodiment, in order to facilitate the installation and placement of the detection device, the pressing strip 17 is an L-shaped structure, and one end of the pressing strip 17 extends into the interior of the extension seat 14. The maximum length of the extended end of the pressing strip 17 is half the diameter of the cavity of the extension seat 14. On the one hand, the pressing strip has a pressing effect on the detection device. On the other hand, since the pressing strip 17 does not extend long in the cavity, when installing the detection device, it is only necessary to move the pressing strip 17 upwards a short distance, and the upper part of the cavity can be placed in the detection device, making the placement of the detection device more convenient.
[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
