“Petit CTG – Melody i” Mobile wireless fetal monitor, made in Japan

You can use it anywhere, at any time.


The Petit CTG – Melody i – is a small and smart, mobile fetal monitoring device, able to assist doctor’s tough situations swiftly.
The system comprises of a fetal heart monitor, a uterine contraction monitor, and a tablet. It has a built-in speaker in the transducer, so it can also be used as a fetal doppler. Thus, the process of fetal monitoring can be streamlined.
“Petit CTG – Melody i” is one of a kind instruments in the world with its wireless monitors, internet connection, and tablet display. Maternal and fetal conditions can be checked via the internet even at distant locations.

Innovative Technologies

 

While maintaining satisfactory measuring ability, Petit CTG – Melody i is packed with innovative technologies that are incomparable to conventional devices and beyond the medical field’s standard.

It has high quality and multifunction, packed in a small body. It can use various medical situations.
It enables straight forward usability and versatility like never before.

1. Small

Small, Light-weight, and wireless – decreasing expectant mother’s stress

Transducer’s weight is close to that of common smartphones (166g / 137g). When compared to other conventional devices, Petit CTG’s volume and mass are less than 1/20. It only consists of two transducers and tablet for displaying results, getting rid of burdensome big machines and printers that are carried by a cart.
It is completely wireless, and once a tablet is connected to Wi-Fi or 3G/LTE network, an expectant mother can move around freely. Measurement can be done both inside and outside of hospital facilities. During hospital’s busy times, expectant mothers can receive NST exam while they wait, decreasing a stress of waiting for long time, and allowing doctors to better manage and use their time efficiently. Because it is wireless, there is no worry of cable deterioration.

  • One full charging ( about 1 hours) will allow up to 6 hours of measurement. A quick recharging will allow medical personnel to feel safe and secure in busy time.

2. Smart

Easy to find a fetal heart rate – a heart sound can be heard from transducer

Heart shaped transducer emits a fetal heart sound, allowing users to find fetal heart location intuitively. Even an untrained person can detect it easily, making this device an optimum choice for education purpose as well.

Tablet and paperless display – Easy to check and reduces expense

A conventional tablet is used to display CTG graph. It operates on IOS, Android, and Windows devices, and all you have to do is to pair the tablet with transducers via Bluetooth. Measured data can be checked by scrolling a screen, assisting doctors’ quick decision making. Data are securely stored in a server (within a hospital or cloud), providing sense of safety. There are no burden of storing graph papers and managing paper expenses.

Sending data via internet – doctors can analyze data anywhere

After measurement is done, data is transmitted via internet to doctors’ smartphone, tablet and/or PC, and can be simply checked on any internet browser. This convenience will allow doctors to utilize their time productively in midst of their demanding schedule.

Even if no one is able to analyze at the place of measurement, it can be analyzed from a distant location. Expectant mothers who had to travel to secondary or tertiary hospital equipped with conventional CTG device to receive NST exam can now receive a same quality exam at primary care hospitals using Petit CTG and allow specialized doctor at distant hospital to analyze and diagnose the result. Expectant mothers will be free from a burden of having to travel long distance.

3. Simple

Only two buttons on transducers – straight forward usages

Once the pairing of devices with a tablet is done, measuring can be started. On fetal heart rate monitor, there are only two buttons, which are power and volume button. On uterine contraction monitor, there are also only two buttons, which are power and zero-set button. Volume change and zero-set can be controlled from the tablet as well. Such simplicity allows smooth utilization of a device even for a beginner.
With its water drop proof rating of IPX2, transducer can be cleaned with no trouble.

4. Safe

Having passed a strict medical device approval, Petit CTG is a trustworthy device that is being used in well known hospitals in Japan. It is suitable for frequent and long monitoring of high-risk pregnancy such as late child bearing and premature labor. Expectant mothers with risk factors can be monitored at home by wearing this device, while the doctors analyze the result from elsewhere. By screening closely, a quick intervention will become possible, decreasing a risk for unexpected emergency delivery as a result.

Loading Petit CTG on the emergency vehicles (i.e. ambulance, helicopter) will enable data to be sent to doctors and to monitor the condition while being transferred. Hearing heartbeat of a fetus will ease the stress of a mother on board, reducing a chance of experiencing a panic attack. Additionally, by receiving data in an advance, accepting hospital can prepare a treatment plan before arrival, increasing a likelihood of saving a life.

6. Success

“Petit CTG” is also used in Chiang Mai, Thailand, and it has been successful. Cooperation between a hospital with specialized doctors and hospitals without such personnel was made possible by introducing Petit CTG to increase the antenatal checkup rate in order to find mothers with high risk pregnancy earlier and transfer them, contributing to higher chance of survival for expectant mother and fetus.
In reflection to such contribution, Chiang Mai University, who was the main partner in collaborating project, has been awarded a Thailand Best Public Service Award 2017 from the Office of the Public Sector Development Commission. Currently, this project is broadening to cover entire provincial hospitals of Chiang Mai.

Background history

In 1974, Our company’s advisers, Professor Kazuhiro Hara and Professor Yasuhito Takeuchi developed a fetal monitor based on “a theory of real time autocorrelation”. Their technological breakthrough #1 became a world standard, making this principle to be implemented in virtually all the fetal monitor in the world since then.
Melody International Ltd. developed Petit CTG, which is a smallest fetal monitor in the world that uses a principle of “a real time autocorrelation”. Despite its size, Petit CTG has exact same functions as conventional machines. It has been approved by PMDA – Pharmaceuticals and Medical Devices Agency of Japan (Approval Number 230AFBZX00024000). Up until now, such devices were available only inside the hospital, but Petit CTG’s portability allows it to be used at any location.
It is also designed in a manner that even non-medical personnel can use it easily.
