Description

Technical Field

[0001] The invention belongs to the technical field of electroencephalogram (EEG) headbands, and in particular relates to a hand-push paste-injection type EEG headband. Background Art

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

[0003] In the prior art (Patent Application No. CN208677393U, Patent Name: Patent Application for EEG Detection Device Based on Wearable Device), electrode paste from the electrode paste reservoir is evenly applied to each electrode pad using a push rod. This has the advantages of simple structure, ease of use, high operational efficiency, and strong practicality. In the process of implementing this technical solution, it was discovered that the prior art has at least the following problems:

[0004] During the EEG headband rehabilitation care for the patient's head, the electrode paste needs to be manually injected onto several electrodes 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 is affected by the external temperature, the fluidity is even worse. Not only can it not be guaranteed that the electrode paste can effectively reach several electrodes, but it can also not achieve uniformity after the electrode paste reaches several electrodes, and poor contact will still occur. Summary of the Invention

[0044] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0045] like Figures 1-18 As shown, a hand-push paste injection type EEG headband of the present invention comprises a headband frame 1, an outer side of the headband frame 1 is clamped with a headband outer cover 2, and an inner side of the headband frame 1 is clamped with a headband inner cover 3, the bottom of the headband frame 1 is fixedly connected with a top frame 4, one side of the top frame 4 is fixedly connected with a handle, and a push cylinder 5 is laterally fixed on the top of the handle, the headband frame 1, the headband outer cover 2 and the headband inner cover 3 are all made of silicone material to improve the contact comfort between the EEG headband and the patient's head, and the top frame 4, the push cylinder 5, the fixing frame 6 and the blowing frame 7 are all made of lightweight composite plastic material to reduce the overall weight of the EEG headband, one side of the bottom of the headband frame 1 is integrally formed with an edge 18, and a thin-film temperature sensor 19 is embedded on the inner side of the edge 18 to detect the body temperature of the patient's forehead, and a battery box 20 is embedded in the handle to facilitate battery replacement and power supply for electrical components;

[0046] The outer side of the injection barrel 5 is fixedly connected to a fixing frame 6, and both sides of the fixing frame 6 are fixedly connected to a blast frame 7. A manual assembly for manually injecting the electrode paste is provided on the top of the fixing frame 6, and the manual assembly includes a rotating rod 81 that rotates on the top of the fixing frame 6. The top of the rotating rod 81 is fixedly connected to a handle 82, and the bottom of the rotating rod 81 is rotatably connected to a manual drive gear 83. When the battery is low, the electrode paste is squeezed and injected in a manual drive manner;

[0047] An electric component for electric injection of electrode paste is provided in the fixing frame 6 and the injection cylinder 5, and the electric component includes a drive motor 91 fixed on the outside of the fixing frame 6, and the output shaft of the drive motor 91 is fixedly connected to the electric drive gear 92 used in conjunction with the manual drive gear 83, and a three-way valve 99 connected to one end of the injection cylinder 5. When the power is sufficient, the electrode paste is squeezed and injected by electric drive to achieve a rapid switching effect between manual and electric, and a paste injection component for squeezing and injecting electrode paste is provided outside the injection cylinder 5, and the paste injection component includes a material storage pot 101 threadedly connected to the top end of the three-way valve 99, and a cloth head 102 connected to the bottom end of the three-way valve 99 and fixed to the top frame 4, so that the electrode paste can reach the patient's scalp quickly, effectively and evenly, thereby improving the contact stability between the electrode head and the patient's scalp to avoid poor contact.

[0048] like Figure 5-Figure 14 The cam 86 is then released and the cam 87 is engaged with the upper and lower cams 84 and 85, and the cam 88 is then engaged with the lower cam 86 and the lower cam 87.

[0049] The upper and lower insertion holes 84 and 85 are arranged in a circular pattern along the longitudinal axis of the rotating rod 81, which facilitates the positioning of the rotating rod 81 at different positions. The handle 82 is also provided with anti-slip grooves around its periphery to increase the friction coefficient between the hand and the handle 82 and play an anti-slip role.

[0050] The electric assembly also includes a micro cylinder 93 that rotates at the bottom of the fixed frame 6, and the top of the micro cylinder 93 is fixedly connected to a differential gear 94 that switches with the manual drive gear 83. The inner side of the fixed frame 6 is rotatably connected to a driven gear 95. The micro cylinder 93 drives the differential gear 94 to move up and is stuck to the meshing portion of the electric drive gear 92 and the driven gear 95. The drive motor 91 drives the driven gear 95 to rotate in succession through the electric drive gear 92 and the differential gear 94 on the micro cylinder 93. Electric measures are taken, and the driven gear 95 is fixedly connected inside. There is a reciprocating screw 96, on which a screw cylinder 97 is threadedly connected, and a piston head 98 that slides with the injection cylinder 5 is fixed on the inner side of the screw cylinder 97 through a bearing. A metering sensor 12 is embedded in 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 manually or electrically to drive the screw cylinder 97 on the reciprocating screw 96 to move back and forth horizontally. The back-and-forth displacement of the screw cylinder 97 drives the piston head 98 to reciprocate in the injection cylinder 5 to provide extrusion force for subsequent injection of the electrode paste.

[0051] The paste injection assembly also includes a distribution tube 103 connected to the four sides of the distribution head 102 and embedded in the top frame 4, and the bottom end of the distribution tube 103 is connected to the main cache head 104 embedded in the head ring frame 1, and the pressure force generated by the reciprocating work in the injection cylinder 5 squeezes the electrode paste in the storage pot 101 into the distribution head 102 through the three-way valve 99, and then the electrode paste reaching the distribution head 102 is supplied to several groups of main cache heads 104 through several distribution tubes 103, the outer end of the main cache head 104 is connected to a three-way pipe 105, and the upper and lower ends of the three-way pipe 105 are connected to the auxiliary cache heads 106 embedded in the head ring frame 1, the main cache head 104 and the auxiliary cache head 10 The inner end of the headband 6 is connected to a flat tube 107 embedded with the headband frame 1 and the headband inner cover 3, and the ends of the flat tube 107 away from the main buffer head 104 and the auxiliary buffer head 106 are respectively provided with a main electrode head 108 and an auxiliary electrode head 109. Then, the electrode paste is supplied to the plurality of groups of auxiliary buffer heads 106 through a plurality of tee tubes 105. The electrode paste in the plurality of groups of main buffer heads 104 and auxiliary buffer heads 106 is then uniformly and effectively delivered to the scalp area through the plurality of flat tubes 107 through the plurality of groups of main electrode heads 108 and auxiliary electrode heads 109, thereby improving the contact stability between the plurality of groups of main electrode heads 108 and auxiliary electrode heads 109 and the patient's scalp to avoid poor contact.

[0052] The main buffer head 104 and the auxiliary buffer head 106 are arranged in a staggered manner along the longitudinal axis of the head ring frame 1, and the patient's head is fully coated with electrode paste and electrode detection is performed. The inner cavity of the flat tube 107 is respectively embedded with a flow-equalizing net 13 and a guide plate 14, and the mesh states of the flow-equalizing net 13 and the guide plate 14 are different. The electrode paste passing through the flat tube 107 is subjected to flow-equalizing and flow-guiding treatment to avoid uneven coating of the electrode paste. The inner end arrays of the main electrode head 108 and the auxiliary electrode head 109 are opened. There are paste injection holes 15 that are connected to the flow-equalizing network 13 and the guide plate 14, so that the electrode paste can be evenly and effectively coated on the scalp, improving the contact stability between the main electrode head 108 and the auxiliary electrode head 109 and the patient's scalp. The inner cavity of the head ring frame 1 is provided with an elastic ring 16 to improve the wearing stability and restraint between the head ring frame 1 and the patient's head, and the elastic ring 16 is provided with reserved openings 17 around the four sides for penetrating and cooperating with the flat tube 107, which plays a role in penetrating and connecting the flat tube 107.

[0053] like Figure 15-18 As shown, since the electrode paste itself is relatively viscous, the fluidity of the electrode paste is even worse under the influence of external low temperature, and the heating and dilution effect cannot be achieved during the addition and injection of the electrode paste. This not only increases the difficulty of manual or electric injection of 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 blower frame 7, and the dilution component includes a micro heater 111 connected to the blower frame 7. Two groups of micro heaters 111 provide heat source supply to the two groups of blower frames 7, and the reciprocating screw 96 is close to the driven gear. One side of 95 is fixedly connected to a main circular gear 112, and both sides of the main circular gear 112 are meshed with slave circular gears 113 that rotate with the blast rack 7. The inner side of the slave circular gear 113 is fixedly connected to a small impeller 114 used in conjunction with the blast rack 7 through a fan shaft, and the inner side of the blast rack 7 is connected to a heat supply head 115. The reciprocating screw 96 drives the slave circular gears 113 on both sides of the main circular gear 112 to rotate. The two groups of slave circular gears 113 drive the two groups of small impellers 114 to rotate in the two groups of blast racks 7 and supply the heat source reaching therein to the two heat supply heads 115.

[0054] The inner end of the heat delivery head 115 is connected to a booster tube 116, and the end of the booster tube 116 is connected to a three-way head 117. The upper and lower ends of the three-way head 117 are respectively connected to a heating rod 118 that penetrates and cooperates with the storage pot 101, and a heating tube 119 that is connected and cooperates with the cloth head 102. The heat source is passed through the three-way heads 117 on the two booster tubes 116 to reach the two heating rods 118 and the heating tube 119 in turn, and the electrode paste added to the storage pot 101 and the electrode paste reaching the cloth head 102 are heated and diluted respectively to prevent the electrode paste from solidifying due to the influence of external low temperature, thereby improving the fluidity of the electrode paste, facilitating the rapid injection and uniform distribution of the electrode paste, and further improving the accuracy of the EEG headband in receiving head signals.

[0055] The working principle of a hand-push paste-injected EEG headband: with the elastic binding of the elastic ring 16, the headband frame 1 and its entirety are worn on the patient's head, so that the several main electrode heads 108 and the secondary electrode heads 109 in the inner cover 3 of the headband are tightly attached to the scalp, and the top frame 4 covers the top of the patient's head. The thin-film temperature sensor 19 at the upper edge 18 of the headband frame 1 is in contact with the patient's forehead for body temperature monitoring. When the power is insufficient and manual drive is required, first pull the lifting head 88 outward to pull the sliding positioning rod 87 on the ear seat 86 out of the lower socket 85 on the rotating rod 81, and after stretching the limit spring 89, hold the handle 82 tightly to drive the manual drive gear 83 on the rotating rod 81 to move down and get stuck in the electric drive gear 92 and the driven gear 95. After the engagement portion, the lifting head 88 is immediately released, and the positioning rod 87 is forced to slide into the upper socket 84 on the rotating rod 81 by the rapidly contracting limit spring 89, and the manual drive gear 83 on the rotating rod 81 after it is in place is limited. At this time, the driving motor 91 is in the unlocked state, and the electric drive gear 92 provides lateral stable rotation support for the manual drive gear 83 that is engaged in place. Then, the grip 82 is tightened to drive the driven gear 95 to rotate manually through the manual drive gear 83 engaged in place on the rotating rod 81. The driven gear 95 drives the reciprocating screw 96 to rotate accordingly. The reciprocating screw 96 drives the screw long tube 97 to move back and forth horizontally, and the screw long tube 97 drives the piston head 98 to perform manual reciprocating work in the injection cylinder 5;

[0056] When the power is sufficient and the electric drive mode is required, on the contrary, the lifting head 88 is first pulled outward to pull the positioning rod 87 sliding on the ear seat 86 out of the upper socket 84 on the rotating rod 81, and after stretching the limit spring 89, the handle 82 is tightened to drive the manual drive gear 83 on the rotating rod 81 to move up and disengage the meshing portion between the electric drive gear 92 and the driven gear 95. After that, the lifting head 88 is immediately released, and the positioning rod 87 is forced to slide inward again into the lower socket 85 on the rotating rod 81 by the rapidly contracted limit spring 89, and the manual drive gear 83 on the reset rotating rod 81 is limited. The micro cylinder 93 is first controlled to open and drive the differential gear 94 to move up and be stuck to the electric drive gear After the meshing portion of the wheel 92 and the driven gear 95 is engaged, the drive motor 91 is controlled to be turned on and the differential gear 94 meshed in place on the micro cylinder 93 is driven to rotate through the electric drive gear 92. The differential gear 94 then drives the reciprocating screw 96 to rotate electrically through the meshed driven gear 95. The reciprocating screw 96 drives the screw long tube 97 to move back and forth horizontally. The screw long tube 97 drives the piston head 98 to perform electric reciprocating work in the injection cylinder 5. When the electric drive mode needs to be released, the drive motor 91 is first controlled to be turned off, and then the micro cylinder 93 is controlled to be turned off and the differential gear 94 is driven to move downward to disengage the meshing portion of the electric drive gear 92 and the driven gear 95 to the initial position.

[0057] The metering sensor 12 quantitatively monitors the electrode paste flowing through the three-way valve 99. The pressure force generated by the piston head 98 that is manually or electrically reciprocating in the injection cylinder 5 is used to supply the material storage pot 101 into the distribution head 102 through the three-way valve 99, and then to several groups of main buffer heads 104 through several distribution pipes 103. Then, it is supplied to several groups of staggered auxiliary buffer heads 106 through several three-way pipes 105. At this point, the electrode paste in several groups of main buffer heads 104 and auxiliary buffer heads 106 passes through the flow-sharing network 13 and the guide pipes in several flat tubes 107. After the flow plate 14 evenly guides the flow, the paste is evenly applied to the multiple detection positions of the patient's head by the EEG headband through the paste injection holes 15 on the multiple main electrode heads 108 and the secondary electrode heads 109 that are close to the scalp. With the cooperation of the electrode paste that evenly and effectively reaches the multiple main electrode heads 108 and the secondary electrode heads 109 and the patient's scalp, the multiple main electrode heads 108 and the secondary electrode heads 109 are in stable contact with the patient's scalp. The EEG headband then monitors and collects information from the multiple detection positions of the patient's head through the multiple main electrode heads 108 and the secondary electrode heads 109 with stable contact;

[0058] During this period, the two groups of micro-heaters 111 are controlled to turn on in advance and the generated heat source is supplied to the two groups of blowing frames 7, and the reciprocating screw 96 driven manually or electrically drives the main circular gear 112 to rotate synchronously. The main circular gear 112 drives the two groups of small impellers 114 on the circular gears 113 to rotate in the two groups of blowing frames 7, and the heat source supplied thereto is blown into the booster pipe 116 on the two groups of heat supply heads 115, and then the two heat sources are passed through two three-way heads 117 to reach the two heating rods 118 and the heating tubes 119. The two heating rods 118 respectively pre-heat and dilute the electrode paste added to the storage pot 101, and the two heating tubes 119 re-heat and dilute the electrode paste supplied to the distribution head 102 to improve its fluidity, so that the electrode paste can be quickly and evenly injected and distributed between several main electrode heads 108 and auxiliary electrode heads 109 and the patient's scalp.

[0059] It should be noted that the specific models and specifications of the drive motor 91, micro cylinder 93 and micro heater 111 need to be selected and determined based on the actual specifications of the device.
