Description

Technical Field

[0001] The present invention relates to the technology of medical devices, and particularly to a wireless intelligent dysphagia treatment instrument. Background Art

[0002] Tongue muscle pressure refers to the pressure generated by the contact between the tongue and the hard palate, which is crucial for the transportation of food. Tongue muscle pressure will be adjusted according to the size and shape of food, age, gender, and the change of eating posture. Currently, in the treatment of tongue pressure dysphagia, there is a traditional balloon dilation therapy, and another is the use of assistive devices. The Iowa Oral Performance Instrument (IOPI) widely used in the United States is also one of the most representative products. In 2002, Hayashi et al. invented a handheld tongue pressure measuring instrument, in which the pressure is transmitted to the pressure sensor through air flow by a balloon connected to the end of a syringe.

[0003] With the development of the medical field, the measurement and evaluation of tongue muscle pressure provide important safety reference indicators for the treatment of dysphagia. The traditional balloon dilation therapy requires nasal or laryngeal intubation of a balloon catheter, which has certain limitations in treatment and operation, is prone to bring more complications, and the treatment experience of patients is not good. The handheld tongue pressure measuring instrument invented by JMS can only perform single-site training for tongue muscle resistance at a time, focusing on the maximum isometric contraction force, target muscle strength, and endurance training of the tongue muscle, and cannot reflect the sequential changes of tongue pressure during swallowing. At the same time, the JMS product is prone to pressure leakage, resulting in errors in data measurement or zero drift. And currently, the detection accuracy of its existing treatment instruments is poor. Summary of the Invention

[0016] The present invention has the following advantages compared with the prior art:

[0017] 1. The tongue pressure handle in this wireless intelligent dysphagia treatment instrument is mainly composed of a control handset, a sensor assembly and an airbag assembly. Among them, the airbag, the connecting plate and the PCB board are connected together to form a sealed detection cavity.

Detailed Embodiments

[0035] The present invention will be further described below in conjunction with the drawings and embodiments.

[0036] As Figures 1 to 5The shown wireless intelligent dysphagia treatment instrument includes a tongue pressure handle, and the tongue pressure handle includes a control handle, a sensor assembly and an airbag assembly. One end of the control handle is provided with a flexible tongue pressure head, and the sensor assembly and the airbag assembly are assembled together and then embedded in the flexible tongue pressure head. The sensor assembly includes a PCB board and a sensor, the sensor is installed on the PCB board, the airbag assembly includes a connecting plate and an airbag, the connecting plate is connected to the PCB board, and the open end of the airbag is hermetically connected to the connecting plate. The airbag, the connecting plate and the PCB board are connected together to form a sealed detection cavity. The detection end of the sensor is located in the detection cavity, and an inert gas is injected into the detection cavity.

[0037] Specifically, the sensor assembly is mainly composed of a PCB board and a sensor. The sensor uses a MEMS pressure sensor, and multiple sensors are installed on the front of the PCB board in a matrix distribution manner. At the same time, electrodes are provided on the front of the PCB board, and the airbag assembly is provided with an assembly hole. The open end of the airbag is hermetically connected to the connecting plate, and the airbag covers the assembly hole. When the connecting plate is welded to the PCB board, the sensor passes through the assembly hole and extends into the airbag, and the airbag, the connecting plate and the PCB board are connected together to form a sealed detection cavity. To ensure that there is a certain air pressure in the detection cavity, an inflation hole is provided on the back of the PCB board, and this inflation hole communicates with the detection cavity. After the connecting plate is welded to the PCB board, an inert gas is injected into the detection cavity through the inflation hole, and then the inflation hole is sealed with a sealant, so that the detection cavity has a certain air pressure and forms a sealed cavity. Then the sensor located in the detection cavity stably and real-time detects the pressure changes generated by the deformation of the detection cavity squeezed in all directions and transmits data outward, ensuring the accuracy of the detection. At the same time, the detection cavity is composed of a flexible structure airbag, which can well contact the contact surface of the tongue completely in various irregular shapes and also reduces the foreign body sensation of the tongue in the oral cavity. Moreover, the detection cavity composed of the airbag structure conducts pressure detection, effectively increasing the matrix effect of the detection points. During the actual treatment evaluation process, the therapist can evaluate the changes in the tongue muscle strength at each point in real time. And a metal electrode seat is provided at the bottom of the assembly hole, and this metal electrode seat is connected to the main control circuit board in the control handle through a wire, and the metal electrode seat is connected to the electrode, so as to transmit current to the electrode.

[0038] The flexible tongue pressure head is made of silica gel, and it is mainly composed of a connecting part and a pressing part. The connecting part and the pressing part are integrally formed. One end of the connecting part is connected to the handle part, and the pressing part is provided with a slot, and the assembled sensor assembly and airbag assembly are embedded in the slot. The flexible tongue pressure head is made of silica gel so that the flexible tongue pressure head has a certain elasticity, thereby improving the comfort of the tongue pressure head during detection in the oral cavity. At the same time, the flexible tongue pressure head and the control handle made of plastic can be connected together by die casting or molding, making the waterproof performance of the combined part of plastic and silica gel more reliable.

[0039] The sensor includes a calibration output unit and a plurality of MEMS barometric pressure sensors. The plurality of MEMS barometric pressure sensors are all connected to a control handle through the calibration output unit, and the plurality of MEMS barometric pressure sensors are distributed in a matrix on the front side of the PCB board. Specifically, as Figure 6 shown, the interface GND on the MEMS barometric pressure sensor is connected and conducted to the ground, and ADD is connected to an external power supply to ensure the effective energy supply in the module; at the same time, the SCL and SDA interfaces are connected to the I / O interfaces on the micro control unit MCU, and the SCL and SDA interfaces on the MEMS barometric pressure sensor are connected to the I / O interfaces on the micro control unit MCU.

[0040] In this embodiment, the number of MEMS is 9. These 9 MEMS barometric pressure sensors are distributed in a matrix on the front side of the PCB board. At the same time, 4 electrodes are also provided on the front side of the PCB board, and the 4 electrodes all pass through the bottom plate and the protective film in sequence. If 9 MEMS barometric pressure sensors are used, the number of air bags is also 9. These 9 air bags are distributed in a 9-point matrix on the front side of the connecting plate, so that it is easier to detect the sequential change of the tongue muscle pressure. The calibration output unit is connected to the main control circuit board of the control handle through a connecting band, and the electrodes are connected to the main control circuit board through wires. A guiding groove is provided at the connecting part of the flexible tongue pressure head, and the wires and the connecting band are arranged along the guiding groove, so as to avoid the problem of route entanglement. At the same time, the MEMS barometric pressure sensor can provide a good treatment basis for the stimulating function of the electrodes, thus facilitating the treatment of the therapist. The calibration output unit is a micro control unit MCU. Combined with the external air pressure calibration and compensation of the air bag, the micro control unit MCU can ensure that the data detected by the MEMS barometric pressure sensor is transmitted to the single chip microcomputer in the logic processing module with high precision. Compared with the existing thin film contact type pressure sensor, the sensor of the present invention can avoid the situation of data drift or the defect of inability to return to zero calibration caused by the self-deformation of the thin film sensor material.

[0041] The described wireless intelligent dysphagia treatment instrument further includes a silica gel protective cover. The silica gel protective cover includes a cover body and a protective film, and the cover body and the protective film are integrally formed; the cover body covers the flexible tongue pressure head, the sensor assembly and the air bag assembly, and the inner wall of the protective film is closely attached to the outer wall of the air bag. The silica gel protective cover in this embodiment can be a disposable silica gel protective cover, which can play a role in protecting components such as the air bag, and at the same time further improves the waterproof effect.

[0042] The control handle includes a handle part and a main control circuit board. The main control circuit board is installed inside the handle part and is connected to the electrodes in the sensor assembly. The main control circuit board is provided with a signal acquisition circuit and a logic processing module. The input end of the signal acquisition circuit is connected to the calibration output unit, and the output end of the signal acquisition circuit is connected to the logic processing module through a Σ-Δ A / D converter. The logic processing module includes a single-chip microcomputer and a power-on reset circuit. The single-chip microcomputer is connected to the signal acquisition circuit through a Σ-Δ A / D converter, and the power-on reset circuit is connected to the single-chip microcomputer. As shown in Figure 7, the signal acquisition circuit is mainly composed of a resistor R1, a resistor R2, a resistor R3, a capacitor C1, a capacitor C2, and an integrated operational amplifier U1B. Among them, the resistor R1 is connected to the sensor, and one ends of the resistor R2 and the capacitor C1 are both connected to the inverting input end of the integrated operational amplifier U1B, and the other ends are both grounded. One end of the capacitor C2 and one end of the resistor R3 are both connected to the single-chip microcomputer through a Σ-Δ A / D converter, and the other end of the capacitor C2 is grounded, and the other end of the resistor R3 is connected to the output end of the integrated operational amplifier U1B.

[0043] The logic processing module includes a single-chip microcomputer and a power-on reset circuit. The single-chip microcomputer is connected to the signal acquisition circuit through a Σ-Δ A / D converter, the power-on reset circuit is connected to the single-chip microcomputer, and the single-chip microcomputer is connected to the calibration output module. As Figure 8 shown, the power-on reset circuit is mainly composed of a resistor R4, a resistor R5, a resistor R6, a capacitor C8, a capacitor C3, a zener diode D1, and an integrated operational amplifier U2B. Among them, one end of the capacitor C3 is connected to the inverting input end of U2B and is connected to the zener diode D1 and then connected to the VDD terminal, and the other end is grounded. The resistor R5 and the resistor R7 are connected in series and then connected to the power supply VDD and are connected to the inverting input end of the integrated operational amplifier U2B, and the other end is grounded. The output end of the integrated operational amplifier U2B is connected to the single-chip microcomputer. Using this power-on reset circuit can effectively solve the following problems: 1) When the interval of the secondary switch of the power supply is too short, the reset is unreliable; 2) When there is a surge phenomenon in the power supply voltage, a reset pulse may not be generated after the surge disappears. Thus, it ensures that the single-chip microcomputer processes the data transmitted by the signal acquisition circuit with high precision. At the same time, in the initial compensation of the calibration output unit, the Σ-Δ A / D converter and the single-chip microcomputer jointly ensure that the sensor signal obtains sufficient compensated temperature and accurate pressure signal output, thereby ensuring that the data detected by the MEMS barometric pressure sensor is accurately transmitted, providing a reliable basis for subsequent treatment.

[0044] The control handle further includes a main controller chip, and the main control circuit board is connected to the main controller chip. The main control circuit board transmits the data detected by the MEMS barometric pressure sensor to the main controller chip, and this main controller chip processes the data and determines a treatment plan based on the data to control the main control circuit board to excite and output current to the electrodes, so as to perform electrical stimulation on the patient's tongue muscles to achieve rehabilitation treatment.

[0045] The handle portion is provided with a control lamp and a control button, and both the control lamp and the control button are connected to the main control circuit board. This structure is simple and convenient for medical staff to operate the tongue pressure handle.

[0046] The wireless intelligent dysphagia treatment device further includes a portable control machine, which includes a control main board and a display screen. The control main board is connected to the display screen, and the control main board is connected to the tongue pressure handle through a wireless communication module. Specifically, the control main board is connected to the main control circuit board of the tongue pressure handle through a wireless communication module, and the wireless communication module can adopt Bluetooth or WIFI. In this embodiment, the wireless communication module adopts a Bluetooth communication module, specifically Bluetooth 4.2. Since the portable control machine and the tongue pressure handle are wirelessly connected, the portable control machine can implement, in addition to the standard "one-to-one" hospital and home use modes where one portable control machine monitors one tongue pressure treatment handle, the "one machine with multiple heads" mode of the present invention. That is, in a hospital or clinic scenario, a set of portable control machines can intelligently manage and monitor the data exchange and monitoring functions of two or more tongue pressure handles, greatly improving the work efficiency of therapists, shortening the waiting queue time for patients, and saving a large amount of medical resource allocation.

[0047] The above specific implementation manners are the preferred embodiments of the present invention and cannot limit the present invention. Any other changes or other equivalent replacement methods made without departing from the technical solutions of the present invention are included in the protection scope of the present invention.
