Abstract

The utility model relates to a device for utilizing biofeedback to treat bruxism, wherein a host module is connected with a detection module wirelessly to avoid wired connection; the output of a sensor in the detection module is connected with a signal filtration amplifier circuit whose output is connected with a single chip; the single chip is connected with a wireless transmission circuit; the single chip of the host module is respectively connected with a wireless receiver, a sound drive circuit and a vibration drive circuit. The utility model resolves the defects of prior art such as that the electrodes are contacted with masticatory muscles on face to affect sleeping, and the muscular and electric signals have strong interference to cause overmedication. The device adopts biofeedback therapy, utilizes an occlude plate, and embeds a sensor at the tooth part of the occlude plate to collect bruxism information to be transmitted to the host via wireless transmission, thereby starting the sound or vibration module to prompt patient about stopping bruxism.

Description

Biofeedback therapy odontorisis device

Technical field

This utility model relates to a kind of therapy equipment, particularly a kind of device that utilizes the biofeedback therapy odontorisis.

Background technology

Odontorisis is meant that the tooth mill of sounding when non-physiological function is moved is moving or stings tight phenomenon.Bruxism can cause tooth wear, aches, responsive, can not chew, severe patient can cause that head, pain neck shoulder are ached, the lower jaw destruction of joint, influences patient health.

Before the present utility model, the present monitor therapy equipment of grinding one's teeth in sleep only is to adopt EMG feedback therapy, they all are the electromyographic signals of gathering masticatory muscles by electrode, connecting LCD display shows, stimulate masticatory muscles by output electric pulse again, reach and loosen masticatory muscles, slow down the outbreak of odontorisis.There is following shortcoming in it: the one, and electrode is affixed on facial masticatory muscles, influences patient's sleep; The 2nd, the interference of electromyographic signal is strong, occurs the over-drastic problem of treatment easily.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned defective, the device of design, a kind of biofeedback therapy odontorisis of development.

The technical solution of the utility model is:

Biofeedback therapy odontorisis device, its major technique are characterised in that host module and detection module wireless connections, have avoided direct lead-in wire to connect; Pick off output connects the signal filtering amplifying circuit in the detection module, and the output of signal filtering amplifying circuit connects single-chip microcomputer, and single-chip microcomputer connects wireless transmission circuit; Single-chip microcomputer connects wireless receiving, voice drive circuit, vibratory drive circuit respectively in the host module.

Advantage of the present utility model and effect are to adopt biofeedback therapy, in conjunction with mouth guard, and the intensive treatment effect.Pick off is embedded in mouth guard canine tooth part, adopts the medical single-chip microcomputer MSP430 of low-power consumption to gather the information of grinding one's teeth in sleep, and utilizes less radio-frequency that information is sent to main frame, judge through main frame, think the symptom of grinding one's teeth in sleep, can start sound or vibration module, remind the patient to stop to grind one's teeth in sleep.

Other advantages of the present utility model and effect will continue to describe below.

The specific embodiment

Principle summary of the present utility model:

Utilize microminiaturized detection module, be embedded in the mouth guard commonly used clinically, combine together with mouth guard.After detection module detects the information of grinding one's teeth in sleep, by wireless mode information is sent in the host module, host module is responsible for receiving the information of grinding one's teeth in sleep and the storage from detection module, utilize USB interface to be connected with computer, judge the state of an illness of using the patient for the doctor, host module can be worn on the user arm, host module detect grind one's teeth in sleep after, then start sound or vibration, remind the patient to stop to grind one's teeth in sleep.

Be of the present utility model specifying below.

As shown in Figure 1:

This device mainly comprises host module, detection module two parts.Wherein, host module mainly comprises single-chip microcomputer 1, wireless receiving circuit 2, LCD demonstration 3, data storage 4, voice drive circuit 5, vibratory drive circuit 6 and USB interface 7 parts; Single-chip microcomputer 1 connects wireless receiving circuit 2, LCD demonstration 3, data storage 4, voice drive circuit 5, vibratory drive circuit 6 respectively in the host module.

As shown in Figure 2:

Detection module mainly comprises pick off 8, signal filtering amplifying circuit 9, single-chip microcomputer 10 and wireless transmission circuit 11 parts composition; Pick off 8 outputs connect signal filtering amplifying circuit 9 in the detection module, and 9 outputs of signal filtering amplifying circuit connect single-chip microcomputer 10, and single-chip microcomputer 10 connects wireless transmission circuit 11.

As shown in Figure 3:

Detection module and mouth guard 13 combine, and pick off 8 is embedded in mouth guard 13 canine tooth parts, and 12 on battery is embedded in a rear flank tooth part of mouth guard; Signal filtering amplifying circuit 9, single-

chip microcomputer

10 and 11 of wireless transmission circuit are formed the opposite side backteeth part that a micro-circuit board 14 is embedded in mouth guard 13.

Concrete use:

The signals collecting of grinding one's teeth in sleep:

By being attached to the pick off 8 at mouth guard eyetooth position, the collection dynamics signal of grinding one's teeth in sleep, the signal that collects carries out filtering by signal filtering amplifying circuit 9 and amplifies, 16 A/D converters that become by chip integration convert digital signal to then, single-chip microcomputer 10 is responsible for data are received, and data are sent by wireless sending module 11, receive for host module.

Sound and vibrational feedback:

When the dynamics of grinding one's teeth in sleep reaches certain threshold value (threshold value is adjustable between 0～9), (being consecutively detected the information of grinding one's teeth in sleep more than the 10hz) when the frequency of perhaps grinding one's teeth in sleep is too high and must giving patient suitably stimulates.Adopt two kinds of biofeedback modes to stimulate patient.First kind is sound, sounds when needs and will send signal by main frame when patient waken up, starts sound module 5 work.Second kind is vibration signal, because instrument and equipment is small and exquisite, can be fixed on patient's arm as mobile phone, under the situation of needs, produces the vibratory stimulation patient, reaches and eliminates the purpose of grinding one's teeth in sleep.

Wireless data transmission:

This utility model has been equipped with wireless data transmission function, makes this device be divided into two partly, has avoided the connection lead-in wire between detection module and the host module, connects the sleep that lead-in wire can influence user.Detection module starts wireless transmission circuit 11 after detecting the signal of grinding one's teeth in sleep, and the information of grinding one's teeth in sleep is sent on the single-chip microcomputer of host module.

Data storage and utilization:

This utility model be equipped with data storage function, can with computer interface.The information of grinding one's teeth in sleep that user is all is stored in the data storage 4, and the doctor can be connected with computer by USB interface 7 when needed, accesses the information of depositing on computers, is convenient to the doctor and understands the state of an illness.
