Nausea and vomiting control device using low frequency stimulation {APPARATUS FOR NAUSEA AND EMESIS CONTROL USING LOW FREQUENCY STIMULUS}

The present invention relates to a nausea and vomiting control device using a low frequency stimulation, and in particular, by separating the unit band worn on the wrist and the main body for generating and controlling the low frequency electrical stimulation signal can prevent the risk of misuse and overuse in advance. The present invention relates to a nausea and vomiting control device using low frequency stimulation that can reduce production costs and prevent unnecessary resource waste by removing unnecessary devices in the consumable unit band.

Many patients complain of recurring nausea or vomiting due to pregnancy or post-operative sequelae or side effects from chemotherapy. Some patients complain of headache, nausea and vomiting due to hangover after drinking.

For example, morning sickness refers to nausea, vomiting, and nausea experienced by pregnant women early in pregnancy, usually complaining at 5-14 weeks of pregnancy. Although the cause of morning sickness has not been scientifically proven, an increase in the human chromosome hormone (Human Chronic Gonadotropin) is known as a primary factor, and psychological and social factors are known to influence. Symptoms associated with morning sickness can include headache, loss of appetite, sleep disorders, fatigue, anxiety, and dizziness.As a result of nutritional imbalances, health problems such as dehydration and weakness can occur. It can also affect your health.

Currently, as a method of suppressing nausea and vomiting, a method of using a chemical composition, that is, a drug, or using acupuncture, acupressure, other radiation devices, and the like is used as a temporary measure.

Among the aforementioned methods, when the chemical agent is used, there is a problem as a general nausea and vomiting treatment method because there is a risk of causing an allergic reaction for certain people.

Acupuncture and acupressure are traditional therapies that produce biological effects by stimulating specific nerves and nerve junctions by poking the skin with fine needles. In this case, however, the skin may be artificially and repetitively wounded, and most of all, the procedure must be performed by a professional practitioner at the place where the treatment tool is provided. Therefore, whenever nausea or vomiting occurs, it is very difficult to immediately and easily treat the problem. have.

On the other hand, although not a dedicated device for the treatment of nausea or vomiting, US Patent No. 4,398,545 discloses a device designed to block the pain shock resulting from injury, US Patent No. 2,223,447 to treat a specific disease Radiotherapy has been disclosed that is not portable.

On the other hand, in each case, when the detection result received from the body temperature sensor 240 or the pulse sensor 250 exceeds the set allowable range, the controller 30 notifies the outside using an alarm unit (not shown). You can do that.

The transmitter 300 transmits the low frequency electrical stimulation signal generated by the main body 100 to the pair of electrodes 220. The transmission unit 300 may connect the main body 100 and the unit band 200 by either a wired or wireless method.

For example, as illustrated in FIGS. 1 and 4, the transmission unit 300 may be provided as a cable that is detachably provided at both ends or one end of the main body 100 or the unit band 200, respectively.

Hereinafter, an operation process of the vomiting control electrical stimulation signal generator 1 according to an embodiment of the present invention having the above-described structure will be described in detail.

First, the main body 100 is operated by selecting the on / off switch 41 of the input unit 40 provided in the main body 100. The display unit 50 displays the remaining charge of the power supply unit 60 and whether or not normal operation. If necessary, for example, when the main body 100 is to be operated at night, the display unit 50 may be viewed by operating the backlight of the display unit 50 using the backlight key 54.

Next, the unit band 200 is connected to the main body 100 using a transmission unit 300, for example, a cable. When the unit band 200 is connected to the main body 100, the controller 30 checks whether the unit band 200 connected through the operation detection sensor 270 provided in the unit band 200 is normally operated. For example, whether or not the check signal is transmitted to the electrode 220 of the unit band 200 by operating the signal generator 20 in the controller 30 and then the test signal in the operation sensor 270 is detected. If it is received normally it can be detected by the control unit 30 to determine the normal operation.

Meanwhile, the controller 30 extracts the operation time counted by the timer 230 of the unit band 200 at the same time as checking the normal operation and compares it with the set usage time. Through this, if the operation time exceeds the usage time, even if the operation operation is input through the input unit 40 to cut off the power supply to the signal generator 20 so that the operation is not made. Here, the controller 30 may be externally recognized through the display unit 50 when the operation time of the timer 230 exceeds the used time.

On the other hand, if the operation time is less than the usage time, the controller 30 waits for the operation input through the input unit 40. The controller 30 may extract the operation time of the timer 230 and display the operation time on the display unit 50 as shown in FIG. 3.

Thereafter, the user or the operator wears the unit band 200 on the user's wrist, and selects an appropriate strength while changing the strength of the unit band 200 through the input unit 40 of the main body 100. The selected intensity may be displayed on the display unit 50 by the controller 30. Alternatively, an auxiliary input unit 260 corresponding to the on / off switch 41 and the intensity control key 42 of the main body 100 may be provided in the unit band 200 so that the user can directly operate the unit band 200. Of course you can.

On the other hand, when the user wants to set the use time of the unit band 200 in advance may be provided with a timer for counting the stimulation time inside the main body 100. In this case, when the time counted by the timer exceeds the set stimulus time, the controller 30 may automatically cut off the power supply to the signal generator 20.

Meanwhile, the unit band 200 may further include a body temperature sensor 240 or a pulse sensor 250. The unit band 200 may measure a user's body temperature or pulse as needed during use and display the same on the display unit 50. .
