Membrane Keypads & Keyboards for Medical & Healthcare Devices

As we are advancing into technology every day, the medical devices employing Membrane Keypads or Keyboards are appearing to be more and more futuristic. Linepro is leader in designing and manufacturing membrane keypads, switches and keyboards for medical equipment since 30 years. The devices which were just a concept on paper a decade ago seem to have arrived at a destination today, owing to our understanding of healthcare industry. The medical and healthcare industry is surely a leading innovator of human-machine interfacing (HMI) technology. HMI devices like Membrane Keypads, switches and keyboards are also being innovated upon due to advancement in medical and healthcare industry.

Linepro feels awarded and appreciated with growing trust of medical and healthcare equipment manufacturers. We have a dedicated Research & Development Center to try and test new technology, after successful experimentation we integrate innovations into our newly developed membrane keypads.

Membrane Switches and Keypads

Our reputation with medical equipment manufacturers is due to the fact that we provide customized solutions for membrane keypads and keyboards. We consult and guide on the selection of circuit substrate, backlighting, overlay material and its graphics.

Membrane Keypad for IV pumps

Linepro’s considerations for designing Medical & Healthcare Membrane Keypads & Keyboards

•Best sealing in segment to prevent liquid ingress. This helps to prevent any form of microbial and chemical contamination
•We have partnered with suppliers providing anti-microbial films to be applied on keypad surface which inhibits bacterial growth
•Our one-piece low profile graphic overlay avoids any sharp edge and component gaps, thereby restricting any contaminant accumulation
•We carefully encapsulate every connector and metal domes behind low profile graphic overlay, which shields the device
•Higher Key Pitch helps in avoiding any accidental press
•We have developed membrane keypads with better tactile feedback experience. This helps for a better response from the switch buttons to the user for the reinsurance that a function has been selected. This is very important for medical and healthcare staff as they need higher level of tactile feedback reinsurance as they always have their hand gloves on
Backlight illumination helps in increased and precise visibility of control parameters of the membrane keypad.

Medical & Healthcare Devices employing Membrane Keypads, Keyboards & Switches and their applications

Membrane Keypads for IV Pumps
membrane keypads and switches for IV pumps

Features: IV pumps incorporate full alphanumeric membrane keyboards to control parameters like infusion rate and volume.

Membrane Keypads for Oxygen Concentrators
membrane keypads and switches for medical oxygen concentrators

Features: Oxygen concentrators are utilized for patients with condition of hypoxia. Membrane keypads for concentrators are used for mode selection and flow control. They also have prominent backlight illumination for better control visibility.

Membrane Keypads for Vital Sign Monitors
membrane keypads and switches for vital sign monitors

Features: Vital Sign Monitors display patient's vital bodily functions in real-time. Membrane Keypads for such monitors have parameters to record, print or menu control.

Membrane Keypads for Hospital Beds

Features: Membrane switches are used in hospital beds to make adjustments to the bed position and patient posture, allowing medical personnel to quickly attend to their patients’ needs.

Membrane Keypads for Defibrillators
membrane keypads and switches for medical defibrillators

Features: These medical devices rescue patients in cardiac arrest by delivering an electric pulse or shock to the heart. Defibrillators must be able to operate in diverse conditions, so membrane switch keypads should be designed with durability in mind. Typical defibrillator membrane keypad functions include energy level selection, energy level charging, and shock administration.

In order to offer you the exact product as per your specs, it is recommended that you provide the following information to us Keyboard can be made with different specs depending on your application. Mainly we need three kinds of information to start a job:

Here you are requested to give dimensions of Keyboard, Display & LED locations, stud size & its location, switch size & its location, connector location and tail length and its location etc.

Here you are advised to provide a detailed circuit diagram (logic Diagram) of electronic components with component specifications including pin numbers of connector. However we recommend to provide us the freedom to select connector pin numbers so that we can minimize the cross connections and reduce the complexity and improve the reliability of the Keyboard. In case of flexible membrane Keyboard, cost of the product will reduce as well.

It is important to select proper overlay material depending upon the application. The most common and economical material is Polycarbonate. We use special grade polyester which is very suitable for embossing and gives good chemical and scratch resistance. In order to make a impressive and attractive overlay, it is important to choose proper color, shade, font size, font shape etc.

Application of the product (consumer, industrial, medical) etc.
Enclosure color
Functional characteristics of LED & Switch

You can choose a combination of matt and glossy finishes on the overlays. We can provide background illumination on selective areas of the Keyboard (Electro-Luminescent Technology).
The aesthetic look of the Keyboard can be further enhanced by embossing the switch and LED areas.
