Cleanable and sterilizable electrical connector for medical devices
Systems and methods are provided for cleanable and sterilizable electrical connector for medical devices. A sterilizable connector may include a first shell and a second shell configured to engage one another, a nose housing that includes a mating area of the connector for engaging a corresponding mating area in a component of a medical device, and an overmolding that overmolds a combination of the first shell, the second shell, and the nose housing. Each of the first shell, the second shell, and the nose housing includes a first material that is compatible with cleaning and sterilization (C&S) treatment. The overmolding includes a second material that provides sealing of the combination of the first shell, the second shell, and the nose housing during the cleaning and sterilization (C&S) treatment. The connector is configured to enable applying at least sterilization without requiring closing or covering of the mating area of the connector.
1. A connector assembly configured for use in a medical device to connect a first component of the medical device to a second component of the medical device, the connector assembly comprising:
a connector that comprises:
a first shell and a second shell, wherein the first shell and the second are configured to engage one another;
a nose housing that comprises a mating area of the connector for engaging a corresponding mating area in one of the first component and the second component; and
an overmolding that overmolds a combination of the first shell, the second shell, and the nose housing;
wherein:
each of the first shell, the second shell, and the nose housing comprises a first material that is compatible with cleaning and sterilization (C&S) treatment of medical equipment; and
the overmolding comprises a second material that provides sealing of the combination of the first shell, the second shell, and the nose housing during the cleaning and sterilization (C&S) treatment; and
a lid configured for engaging the connector, wherein the lid is configured to seal the mating area of the connector during the cleaning and sterilization (C&S) treatment.
2. The connector assembly of claim 1 , wherein the connector is configured to enable applying at least sterilization without requiring closing or covering of the mating area of the connector.
3. The connector assembly of claim 1 , wherein the first material comprises a polymer.
4. The connector assembly of claim 3 , wherein the polymer comprises at least one of polypropylene and polycarbonate.
5. The connector assembly of claim 1 , wherein the second material comprises a thermoplastic polymer.
6. The connector assembly of claim 5 , wherein the thermoplastic polymer comprises thermoplastic vulcanizate (TPV).
7. The connector assembly of claim 1 , wherein the connector further comprises one or more shielding shells configured to provide shielding of electrical components and/or circuitry of the connector disposed within the connector.
8. The connector assembly of claim 7 , wherein each of the one or more shielding shells comprises stamped metal foil.
9. The connector assembly of claim 1 , wherein the lid engages and seals the connector without use of locking mechanism or components.
10. The connector assembly of claim 1 , wherein the lid is configured to enable applying cleaning processing that is compliant with one or more liquid ingress protection ratings.
11. The connector assembly of claim 10 , wherein the one or more liquid ingress protection ratings comprise at least one of Ingress Protection Code IPX6 and Ingress Protection Code IPX7.
12. The connector assembly of claim 1 , wherein the lid comprises at least a lid casing and a sealing component that seals contact between the lid and at least a portion of the connector.
13. The connector assembly of claim 12 , wherein the lid casing comprises same material as the second material used in the overmolding.
14. The connector assembly of claim 1 , wherein the medical device comprises a medical imaging device.
15. The connector assembly of claim 14 , wherein one of the first component and the second component comprises a medical imaging probe.
16. The connector assembly of claim 1 , wherein one or both of the first material and the second material are selected based on selection criteria that comprise being resistant to material or chamicals used in the cleaning and sterilization (C&S) treatment.
