TM-FLOW/CHRONIC CARE SYSTEM (CCS) CLOUD PLATFORM
VASCULAR FUNCTION AND AUTONOMIC NERVOUS SYSTEM DATA MANAGEMENT
The TM-Flow system is a Medical Device Data System (MDDS).
The New version 7 of the TM-Flow system integrates the CCS Cloud to invite specialist MDs to interpret the exam results and expert billing system companies to improve the reimbursement process of the different devices managed by the TM Flow software.
The TM Flow system comprises:
Part 1: Three Devices
The TBL-ABI is:
- A medical device indicated for use on adult subjects at risk of having or developing peripheral arterial disease (PAD)
- Is intended for the rapid measurement of ankle-brachial pressure index (ABPI), or ankle-brachial index (ABI), and pulse volume recording (PVR)/ volume plethysmography in adults.`

The Sweat C is:
- A medical device indicated for use as a galvanic skin response technology related to the sweat gland function. It is used to test the sudomotor function.
- Sudomotor testing using this method “may be the most sensitive means to detect peripheral small fiber neuropathy (Low, et al.,2006).

The Oxi_W is
- A medical device indicated for use:
- 1. To spot check SpO2% and pulse rate
- 2.To analyze the pulse waveform (Photoplethysmography or PPG/PTG) to the assess the microvascular condition
- 3. To analyze heart rate variability to assess the autonomic nervous system function.

Part 2: A dedicated software
Software features
- Manages the 3 devices measurements.
- Sends the data to a dedicated cloud.
- Register the physician and its partners through a web site (www.ldteckcloud.com).
CCS Cloud data management
- Provides access to the patient report and sharing with:
- An Interpreting physician.
- A Billing department
- Displays a final patient report, with a full interpretation, that is available to the ordering physician. It can be printed or sent to an EMR.
Why TM-FLOW/ CCS Cloud Platform?
The 3 medical devices (TBL ABI, OXI W, SweatC) are used by physicians to assess patients who have suffered from complications of chronic diseases.
The devices allow for the early detection of chronic disease complications.
If there is no early diagnostic then there is no timely treatment, and time is of the essence when considering treatment for chronic disease complications.
Peer reviews and clinical studies demonstrate that chronic diseases, as well as their treatments, affect both vascular (endothelial function and Lower extremity artery) and autonomic nervous system (ANS) function (sudomotor and cardiac autonomic function).
How are the data managed with CCS Cloud?
- By using a dedicated secure CDCS Cloud Software.
After each device is used and the measurements are recorded, the software then sends the data to the CCS cloud. The online and secure cloud software allows the invited qualified physicians (neurologist, cardiologist, or vascular specialist), and also billing experts, to provide an interpretation and guidance regarding the device test results related to vascular or ANS functions and billing.
What is the Vision of the TM-Flow/CCS Cloud Platform.
Collaborating as a team to improve patient care.
Effective teamwork between the performing physician and qualified interpreting physician (e.g., specialists) is a must in today’s healthcare environment due to increasing patient comorbidities and the complexity of specialization care required.
The CCS cloud data management platform enables the formation of effective teamwork by helping align primary and specialty care physicians to deliver better patient care.

Oxi_W clinical studies:
- PTG Spectral Analysis Markers return a high specificity and sensitivity to detect:
The ROC curves showed that the most relevant cutoff to the whole study group was a PTG-TP > 406.2. This cut-off had a sensitivity = 95.7%, specificity = 84,4% and the area under the ROC curve (AUC) = 0.929 for identifying insulin resistance. All AUC ROC curve analysis were significant (p < 0.0001).
the PTG CVD score had a sensitivity of 82.5% and specificity of 96.8%, at a cutoff of 2, when used to detect CAD (P=0.0001; area under the receiver operating characteristic curve =0.967). The PTG spectral analysis markers were well-correlated to other autonomic nervous system and endothelial function markers. CAD diabetic patients (n=27) had a lower PTGi value compared with the CAD non-diabetic patients (n=38): and patients that underwent CABG (n=18) had a higher PTGi value compared with the CAD without CABG surgery patients (n=47).
Comparisons between the healthy subjects and type 2 diabetes mellitus patients
The PTGi had a sensitivity of 92% and specificity of 80% (cut-off score > 35.5) with the area under the curve = 0.92 (SE = 0.04; 95% CI = 0.84, 1.0) and an asymptotic significance < 0.001. The PTGVLFi had a sensitivity of 92% and specificity of 87% (cut-off score > 25.5) with the area under the curve = 0.91 (SE = 0.05; 95% CI = 0.81, 1.0) and an asymptotic significance < 0.001.
