Description

Technical Field

[0001] The present invention belongs to the technical field of EEG headbands, and particularly relates to a hand-injected paste type EEG headband. Background Art

[0002] The core function of an EEG headband is to non-invasively capture EEG signals such as theta waves and alpha waves in real time, convert them into quantitative indicators such as concentration and relaxation, support individualized baseline calibration, and then analyze emotional fluctuations (such as anxiety and stress) in combination with AI algorithms to provide instant feedback and intervention suggestions. Finally, gamified interactions (such as virtual racing acceleration and meditation guidance) are used to strengthen the brain's self-regulation ability, improve attention or relieve psychological stress.

[0003] In the prior art (patent application with publication number CN208677393U and patent name EEG detection device based on a wearable device), electrode paste in an electrode paste reservoir can be directly and evenly applied to each electrode sheet through a push rod, which has the advantages of simple structure, convenient use, high operation efficiency, and strong practicability. In the process of implementing this technical solution, it is found that at least the following problems exist in the prior art: During the rehabilitation care of a patient's head using an EEG headband, it is necessary to manually inject electrode paste onto several electrodes that are close to the scalp to ensure the contact stability between the electrodes and the scalp, and then collect the signals transmitted by the head. Since the electrode paste itself is relatively viscous and its fluidity is worse affected by external temperature, not only can it not ensure that the electrode paste effectively reaches several electrodes, but also the uniformity of the electrode paste after reaching several electrodes cannot be achieved, and poor contact still occurs. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems in the prior art that the electrode paste cannot be effectively and evenly injected onto several electrodes based on a driving method that can be switched between manual and electric, resulting in the electrode paste not being injected in place and poor contact occurring.

[0015] The hand-push paste injection type EEG headband of the present invention has the following advantages: 1. For this hand-pushed paste-injected EEG headband, when the battery is low, first pull out the pull head and drive the positioning rod on the ear seat to slide outward, and after stretching the limit spring, the handle drives the manual drive gear to move down through the rotating rod and get stuck in the meshing part of the driven gear. At this time, the electric drive gear on the drive motor is in an unlocked state, and then release the pull head to insert the positioning rod into the upper plug hole on the rotating rod that has moved down to the right position, and take manual drive measures. Conversely, pull up the rotating rod and drive the manual drive gear to disengage from the meshing part of the driven gear to the initial position, and then release the pull head to insert the positioning rod into the lower plug hole on the rotating rod that has moved up and reset, and release the manual drive measures; When the power is sufficient, the micro cylinder first drives the differential gear to move up to the meshing part of the electric drive gear and the driven gear, and then the drive motor drives the driven gear to rotate through the electric drive gear and the differential gear on the micro cylinder. Electric measures are taken, and the driven gear drives the long screw tube on the reciprocating screw to move back and forth horizontally.

This kind of hand-push paste injection type EEG head ring, then, first, the pressure force generated by the reciprocating work in the injection cylinder squeezes the electrode paste in the storage pot into the distribution head through the three-way valve, and then the electrode paste reaching the distribution head is supplied to several groups of main cache heads through several distribution tubes, and then the electrode paste is supplied to several groups of auxiliary cache heads through several three-way tubes. The electrode paste reaching several groups of main cache heads and auxiliary cache heads is then passed through several flat tubes through several groups of main electrode heads and auxiliary electrode heads to evenly and effectively reach the scalp area, thereby improving the contact stability between several groups of main electrode heads and auxiliary electrode heads and the patient's scalp to avoid poor contact.

[0017] 3. For this hand-push paste-type EEG headband, meanwhile, two groups of micro heaters first provide heat source supply to two groups of air blower frames, and the reciprocating lead screw drives the driven circular gears on both sides of the main circular gear to rotate. The two driven circular gears drive two groups of small impellers to rotate in the two air blower frames and supply the heat source reaching therein into two heat delivery heads. Then, it reaches two heating rods and heating tubes through the three-way connectors on two pressurizing tubes, heating and diluting the electrode paste added to the storage pot and the electrode paste reaching the cloth head respectively, so as to prevent the electrode paste from solidifying due to the influence of external low temperature, improve the fluidity of the electrode paste, facilitate the rapid pushing and uniform distribution of the electrode paste, and further improve the accuracy of the EEG headband receiving head signals.

[0021] The following is a specific introduction of the present invention in combination with the accompanying drawings and specific embodiments: As Figures 1 - 18As shown in the figure, a hand-push paste type electroencephalogram headband of the present invention includes a headband skeleton 1. An outer cover 2 of the headband is clamped on the outer side of the headband skeleton 1, and an inner cover 3 of the headband is clamped on the inner side of the headband skeleton 1. A top frame 4 is fixedly connected to the bottom of the headband skeleton 1. A handle is fixedly connected to one side of the top frame 4, and a syringe 5 is horizontally fixed to the top of the handle. The headband skeleton 1, the outer cover 2 of the headband, and the inner cover 3 of the headband are all made of silica gel material to improve the contact comfort between the electroencephalogram headband and the patient's head. Moreover, the top frame 4, the syringe 5, the fixing frame 6, and the air blowing frame 7 are all made of lightweight composite plastic material to reduce the overall weight of the electroencephalogram headband. An edge 18 is integrally formed on one side of the bottom of the headband skeleton 1, and a thin-film type temperature sensor 19 is embedded inside the edge 18 to detect the body temperature of the patient's forehead. Moreover, a battery box 20 is embedded in the handle to facilitate battery replacement and supply power to the electrical components; A fixing frame 6 is fixedly connected to the outer side of the syringe 5, and air blowing frames 7 are fixedly connected to both sides of the fixing frame 6. A manual component for manually injecting electrode paste is arranged on the top of the fixing frame 6. The manual component includes a rotating rod 81 rotating on the top of the fixing frame 6. A handle 82 is fixedly connected to the top of the rotating rod 81, and a manual driving gear 83 is rotatably connected to the bottom of the rotating rod 81. When the power is insufficient, the electrode paste is extruded and injected in a manual driving manner; An electric component for electrically injecting electrode paste is arranged in the fixing frame 6 and the syringe 5. The electric component includes a driving motor 91 fixed to the outer side of the fixing frame 6. An output shaft of the driving motor 91 is fixedly connected to an electric driving gear 92 used in cooperation with the manual driving gear 83, and a three-way valve 99 communicated with one end of the syringe 5. When the power is sufficient, the electrode paste is extruded and injected in an electric driving manner to achieve a quick switching effect between manual and electric. Moreover, an injection paste component for extruding and injecting electrode paste is arranged outside the syringe 5. The injection paste component includes a storage pot 101 threadedly communicated with the top end of the three-way valve 99, and a cloth head 102 communicated with the bottom end of the three-way valve 99 and fixed to the top frame 4, so that the electrode paste can quickly, effectively and evenly reach the patient's scalp, improving the contact stability between the electrode head and the patient's scalp to avoid contact failure.

[0022] As Figures 5 - 14As shown in the figure, the manual component further includes an upper jack 84 and a lower jack 85 opened at the upper and lower positions of the rotating rod 81. One side of the top of the fixing frame 6 is fixedly connected with an ear seat 86. A positioning rod 87 that is inserted and matched with the upper jack 84 and the lower jack 85 is slidably connected in the ear seat 86. A lifting head 88 is fixedly connected to the outer side of the positioning rod 87. A limiting spring 89 that is fixedly matched with the ear seat 86 and the lifting head 88 is sleeved on the positioning rod 87. When the power is insufficient, first pull out the lifting head 88 outward to drive the positioning rod 87 on the ear seat 86 to slide outward. After stretching the limiting spring 89, then drive the manual drive gear 83 to move downward by the handle 82 through the rotating rod 81 and clamp it to the meshing part of the driven gear 95. At this time, the electric drive gear 92 on the drive motor 91 is in an unlocked state. Then release the lifting head 88 and correspondingly insert the positioning rod 87 into the upper jack 84 on the rotating rod 81 after moving downward in place, and take manual drive measures; The upper jack 84 and the lower jack 85 are distributed in a circumferential shape up and down along the longitudinal axis of the rotating rod 81, which is beneficial to the positioning work of the rotating rod 81 at different positions. Anti-slip lines are provided on the periphery of the handle 82 to increase the friction coefficient between the hand and the handle 82 and play an anti-slip role; The electric component further includes a micro cylinder 93 rotating at the bottom of the fixing frame 6. The top of the micro cylinder 93 is fixedly connected with a differential gear 94 that is switched and matched with the manual drive gear 83. A driven gear 95 is rotatably connected to the inner side of the fixing frame 6. The differential gear 94 is driven by the micro cylinder 93 to move upward and clamp it to the meshing part of the electric drive gear 92 and the driven gear 95. The driven gear 95 is successively driven to rotate by the drive motor 91 through the electric drive gear 92 and the differential gear 94 on the micro cylinder 93, and take electric measures. A reciprocating lead screw 96 is fixedly connected inside the driven gear 95. A lead screw barrel 97 is threadedly connected to the reciprocating lead screw 96. A piston head 98 that is slidably matched with the injection cylinder 5 is fixed inside the lead screw barrel 97 through a bearing. A metering sensor 12 is embedded at the outer end of the three-way valve 99 to quantitatively monitor the electrode paste passing through the three-way valve 99. The driven gear 95 is driven in a manual or electric drive mode to drive the lead screw barrel 97 on the reciprocating lead screw 96 to horizontally reciprocate accordingly. The reciprocating lead screw barrel 97 drives the piston head 98 to reciprocate in the injection cylinder 5 to provide an extrusion force for the subsequent injection of the electrode paste.

[0023] The paste injection assembly further includes a cloth tube 103 connected around the cloth head 102 and embedded with the top frame 4, and the bottom end of the cloth tube 103 is connected with a main buffer head 104 embedded and matched with the head ring skeleton 1. The pressure generated by the reciprocating work in the injection cylinder 5 squeezes and injects the electrode paste in the material storage pot 101 into the cloth head 102 through the three-way valve 99, and then supplies the electrode paste reaching the cloth head 102 into several groups of main buffer heads 104 through several cloth tubes 103. The outer end of the main buffer head 104 is connected with a three-way pipe 105, and both the upper and lower ends of the three-way pipe 105 are connected with auxiliary buffer heads 106 embedded and matched with the head ring skeleton 1. The inner ends of the main buffer head 104 and the auxiliary buffer head 106 are connected with flat tubes 107 embedded and matched with the head ring skeleton 1 and the inner head ring cover 3. The ends of the flat tubes 107 far from the main buffer head 104 and the auxiliary buffer head 106 are respectively provided with main electrode heads 108 and auxiliary electrode heads 109. Then, the electrode paste is supplied into several groups of auxiliary buffer heads 106 through several three-way pipes 105. The electrode paste reaching several groups of main buffer heads 104 and auxiliary buffer heads 106 then reaches the scalp area evenly and effectively through several flat tubes 107 and several groups of main electrode heads 108 and auxiliary electrode heads 109, improving the contact stability between several groups of main electrode heads 108 and auxiliary electrode heads 109 and the patient's scalp, so as to avoid the phenomenon of poor contact. Moreover, the main buffer head 104 and the auxiliary buffer head 106 are distributed in a circumferential staggered manner along the longitudinal axis of the head ring skeleton 1 to comprehensively coat the electrode paste and perform electrode detection on the patient's head. Flow equalizing meshes 13 and flow guiding plates 14 are respectively embedded in the inner cavities of the flat tubes 107, and the mesh states of the flow equalizing meshes 13 and the flow guiding plates 14 are different to perform flow equalizing and flow guiding treatments on the electrode paste passing through the flat tubes 107, so as to prevent the electrode paste from being sprayed unevenly during coating. Injection paste dense holes 15 communicating and matching with the flow equalizing meshes 13 and the flow guiding plates 14 are arrayed and opened at the inner ends of the main electrode heads 108 and the auxiliary electrode heads 109, so that the electrode paste is evenly and effectively coated on the scalp, improving the contact stability between the main electrode heads 108 and the auxiliary electrode heads 109 and the patient's scalp. A elastic ring 16 is sleeved in the inner cavity of the head ring skeleton 1 to improve the wearing stability and binding property between the head ring skeleton 1 and the patient's head. And reserved openings 17 penetrating and matching with the flat tubes 107 are opened around the elastic ring 16 to play a role in penetrating and connecting the flat tubes 107.

[0024] Such as Figures 15 - 18As shown, since the electrode paste is relatively viscous, under the influence of low external temperature, the fluidity of the electrode paste becomes even worse. During the addition and injection of the electrode paste, it is impossible to achieve the heating and dilution effect, which not only increases the difficulty of manually or electrically injecting the electrode paste, but also makes it difficult to ensure that the electrode paste is evenly distributed between the electrode and the scalp, resulting in poor contact. A dilution component is provided on the air blowing frame 7, and the dilution component includes a micro heater 111 connected to the air blowing frame 7. The two groups of micro heaters 111 provide heat source supply to the two groups of air blowing frames 7. One side of the reciprocating lead screw 96 close to the driven gear 95 is fixedly connected with a main circular gear 112, and both sides of the main circular gear 112 are engaged with a secondary circular gear 113 rotatably matched with the air blowing frame 7. The inner side of the secondary circular gear 113 is fixedly connected with a small impeller 114 used in conjunction with the air blowing frame 7 through a fan shaft, and the inner side of the air blowing frame 7 is communicated with a heat delivery head 115. The reciprocating lead screw 96 drives the secondary circular gears 113 on both sides of the main circular gear 112 to rotate. The two groups of secondary circular gears 113 drive the two groups of small impellers 114 to rotate in the two groups of air blowing frames 7 and supply the heat source reaching therein into the two heat delivery heads 115; The inner end of the heat delivery head 115 is communicated with a pressure increasing pipe 116, and the end of the pressure increasing pipe 116 is communicated with a three-way head 117. The upper and lower ends of the three-way head 117 are respectively communicated with a heating rod 118 penetrating and cooperating with the storage pot 101, and a heating pipe 119 communicated and cooperating with the cloth head 102. The heat source is sequentially passed through the three-way heads 117 on the two pressure increasing pipes 116 and reaches the two heating rods 118 and the heating pipe 119, respectively heating and diluting the electrode paste added to the storage pot 101 and the electrode paste reaching the cloth head 102, so as to prevent the electrode paste from solidifying due to the influence of low external temperature, improve the fluidity of the electrode paste, facilitate the rapid injection and uniform distribution of the electrode paste, and further improve the accuracy of the brain electro head ring receiving the head signal.

[0025] Working principle of a hand-pushing paste-type EEG headband: Under the elastic restraint of the elastic ring 16, the headband skeleton 1 and its entirety are worn on the patient's head, so that several main electrode heads 108 and sub-electrode heads 109 in the inner headband 3 are closely attached to the scalp, and the top frame 4 covers the patient's head. The thin-film temperature sensor 19 at the upper edge 18 of the headband skeleton 1 is in contact with the patient's forehead for body temperature monitoring. When the power is insufficient and manual driving is required, first pull the lifting head 88 outwards to pull out the positioning rod 87 sliding on the ear seat 86 from the lower jack 85 on the rotating rod 81, and stretch the limiting spring 89. Then, hold the handle 82 tightly and drive the manual driving gear 83 on the rotating rod 81 to move downward and engage with the meshing part of the electric driving gear 92 and the driven gear 95. Immediately release the lifting head 88, and the quickly contracting limiting spring 89 forces the positioning rod 87 to slide inwards and engage with the upper jack 84 on the rotating rod 81 to limit the manual driving gear 83 on the rotating rod 81 in place. At this time, the driving motor 91 is in the unlocked state, and the electric driving gear 92 provides a lateral stable rotation support for the manually driven gear 83 in place. Then, hold the handle 82 tightly and drive the driven gear 95 to rotate manually through the manually driven gear 83 engaged on the rotating rod 81. The driven gear 95 drives the reciprocating lead screw 96 to rotate accordingly. The reciprocating lead screw 96 drives the lead screw cylinder 97 to move horizontally back and forth. The lead screw cylinder 97 drives the piston head 98 to perform manual reciprocating work in the injection cylinder 5; When the power is sufficient and electric driving is required, on the contrary, first pull the lifting head 88 outwards to pull out the positioning rod 87 sliding on the ear seat 86 from the upper jack 84 on the rotating rod 81, and stretch the limiting spring 89. Then, hold the handle 82 tightly and drive the manual driving gear 83 on the rotating rod 81 to move upwards to disengage from the meshing part of the electric driving gear 92 and the driven gear 95. Immediately release the lifting head 88, and the quickly contracting limiting spring 89 forces the positioning rod 87 to slide inwards again and engage with the lower jack 85 on the rotating rod 81 to limit the manually driven gear 83 on the rotating rod 81 after resetting. First, control the micro-cylinder 93 to open and drive the differential gear 94 to move upwards and engage with the meshing part of the electric driving gear 92 and the driven gear 95. Then, control the driving motor 91 to open and drive the differential gear 94 engaged on the micro-cylinder 93 to rotate through the electric driving gear 92. The differential gear 94 then drives the reciprocating lead screw 96 to rotate electrically through the engaged driven gear 95. The reciprocating lead screw 96 drives the lead screw cylinder 97 to move horizontally back and forth. The lead screw cylinder 97 drives the piston head 98 to perform electric reciprocating work in the injection cylinder 5. When it is necessary to cancel the electric driving mode, first control the driving motor 91 to turn off, and then control the micro-cylinder 93 to turn off and drive the differential gear 94 to move downwards to disengage from the meshing part of the electric driving gear 92 and the driven gear 95 to the initial position; Under the quantitative monitoring of the metering sensor 12 for the electrode paste flowing through the three-way valve 99, the pressure generated by the piston head 98 that reciprocates manually or electrically in the injection cylinder 5 passes through the three-way valve 99 to supply the storage pot 101 into the cloth head 102, and then through a number of cloth pipes 103 into a number of main buffer heads 104. After that, it is supplied into a number of staggered secondary buffer heads 106 through a number of three-way pipes 105. Thus, the electrode paste reaching the main buffer heads 104 and the secondary buffer heads 106 is evenly guided by the flow equalizing net 13 and the deflector 14 in a number of flat pipes 107, and finally evenly coated onto a number of detection positions on the patient's head by the paste injection holes 15 on a number of main electrode heads 108 and secondary electrode heads 109 that are close to the scalp. With the cooperation of the electrode paste that evenly and effectively reaches between a number of main electrode heads 108 and secondary electrode heads 109 and the patient's scalp, stable contact is achieved between a number of main electrode heads 108 and secondary electrode heads 109 and the patient's scalp. The electroencephalogram head ring then monitors and collects the information of a number of detection positions on the patient's head through a number of main electrode heads 108 and secondary electrode heads 109 with stable contact; During this period, two groups of micro heaters 111 are controlled to start in advance and the generated heat source is supplied into the two groups of air blowing frames 7. And the reciprocating lead screw 96 driven manually or electrically drives the main circular gear 112 to rotate synchronously. The main circular gear 112 drives the small impellers 114 on the two groups of secondary circular gears 113 to rotate in the two groups of air blowing frames 7, and blows the supplied heat source into the pressure increasing pipes 116 on the two groups of heat supply heads 115. Then, the two-way heat source reaches two heating rods 118 and heating pipes 119 through two three-way heads 117. The two heating rods 118 are used to preheat and dilute the electrode paste added into the storage pot 101 respectively, and the two heating pipes 119 are used to reheat and dilute the electrode paste supplied into the cloth head 102, improving its fluidity, so that the electrode paste is quickly and evenly pushed and distributed between a number of main electrode heads 108 and secondary electrode heads 109 and the patient's scalp.
