Here a rea few project examples from seleon in the field of ventilation.CONTRAST MEDIUM INJECTOR FOR CT
The Contrast Medium Injector was developed by seleon for the intravenous injection of contrast media and isotonic saline solutions for computer tomography in the context of an examination with CT and CT-PET scanners.
seleon was in charge of development through all phases: from the concept to the functional models, prototypes (including approvals) to the transfer to series production. Both project management and the coordination of external project participants were handled by seleon.
With the complete development of the Contrast Medium Injector, the customer has access to seleon’s bundled know-how. The company has detailed documentation, both for matters related to development and for implementation and manufacturing. The customer obtains a high-performance, economically successful device with the best service.STENT COATING SYSTEM
Several steps can be completed in one with the device. The protective cap is removed from the stent with the operation of the lever, and at the same time, the drug is applied and dried with sterile oxygen.
On behalf of the customer, seleon realised the development, production and servicing of the Stent Coating Machine. Numerous technical challenges were associated with this task. For example, a solution was found for the sterile fixation of the stent in the coating machine. Another important requirement was to design the cartridge in which the stent is coated as a low-cost disposable plastic component. User ergonomics, reliability and easy cleaning were other essential considerations that had to be taken into account.
The handling of quality assurance and service by seleon and the international deployment show that development and production from one source promises success.A PHYSIOLOGICAL MEASURING MODULE FOR THE SYNCHRONISATION OF THE ECG DATA WITH THE CT SCAN
For a new generation of CT scanners, a Physiological Measurement Module (PMM) was developed and manufactured for the synchronization of CT imaging with the respiratory or heart rate of the patient.
During data acquisition with the CT scanner, the PMM has to record and analyse physiological data such as the ECG, pulse rate and a respiratory signal. A trigger signal has to be derived from the ECG data in real time, triggering the CT scan in a defined heart phase. The PMM has to be integrated into the foot of the scanner as a self-contained module.
hanks to its in-depth expertise in data analysis, seleon was able to develop a sophisticated ECG analysis procedure. Once the corresponding heart phase is identified based on the ECG data, the module sends a trigger signal to the CT scanner. This permits image capturing in the pause between two heartbeats, regardless of the heart rate or irregularities in the patient’s heartbeat.
Bundling all process steps from development to series production with one vendor and ongoing, transparent reporting to the customer led to the seamless integration of the module into the scanner. With an intelligent controller from the customer, adaptive dosage modulation controlled by the ECG was realised, minimising the radiation exposure in the fast heart movement phases.OXIMETER FOR THE LOCAL MEASUREMENT OF OXYGEN SATURATION IN THE BLOOD
The Oximeter is a measuring device to determine the local oxygen saturation in the blood. It is used at a heart catheter measuring station. It can be used flexibly through its Bluetooth connection to the cardiac catheter measuring station. During an examination using a catheter, it determines the local oxygen saturation in the patient’s heart ventricles without drawing additional blood.
seleon was responsible for the development of the Oximeter up to series readiness of the device. Device features include a compact, robust design, minimal power consumption, wireless operation and wireless data transfer. Various operating states have to be indicated by audible signals. The measuring device has to stand up to surface disinfection.
Usability is improved in particular by the wireless technology. Thanks to wireless transmission of the automatically determined blood oxygen saturation data to the PC, there are no restrictions of movement.THE HAEMO BASE RESEARCH PROJECT
The aim of the research project 'Haemo Base' was to develop an analysis unit to be used in a hemodynamic measurement station in the cardiac catheterization laboratory. The use of the analysis unit was planned for different scenarios:
- As part of a haemodynamic measuring station in the heart catheter laboratory
- As part of a combined hybrid solution with a haemodynamic and electrophysiological diagnostics measuring station
The development has been implemented up to prototypes being produced by seleon. All documents required to prepare for and support medical approval were created. Preparations for medical approval had to be made for the potential markets of Europe, the USA/Canada and other regions.
Thanks to the detailed concept and the associated estimate of the development costs as well as the estimate of the production costs, the customer was able to decided whether to develop the complete system or purchase parts of it.
