Abstract
A naso-gastric tube stabilizer device having a base part, a harness for releasably holding the device on a patient's head, and a spring member secured for releasably securing to the device an exposed section of a naso-gastric tube extending out of the patient's nostril.
Claims10
In a naso-gastric tube stabilizer device for engaging an exposed section of a naso-gastric tube extending out of a patient's nostril, the device including:
- a base adapted to lie against the upper lip of a patient and having a central part with a bearing surface thereon,
- spring means secured on said base for releasably urging said tube section against said bearing surface, and
- connection means coupled to said base for releasably engaging said base to the patient's head and for holding said base such that the spring means and the bearing surface are oriented to secure said tube section in substantial alignment with the nostril of a patient, the improvement wherein said base comprises a support section which includes thereon said bearing surface, and said spring means comprises a body part secured to said base, and an arm part extending from said body part and overlying said bearing surface, said body and arm parts of the spring configured to sandwich between them said support section of the base, whereby resilient force of the arm part applied to said bearing surface or said section of the tube adjacent said bearing surface causes compression of said support section between said arm and body parts without stressing or distorting the remainder of said base.
In a naso-gastric tube stabilizer device for engaging an exposed section of a naso-gastric tube extending out of a patient's nostril, the device including:
- a base adapted to lie against the upper lip of a patient and having a central part with a pair of bearing surfaces thereon,
- spring means on said base for releasably urging said tube section against one of said bearing surfaces, and
- connection means coupled to said base for releasably engaging said base to the patient's head and for holding said base such that the spring means and the bearing surfaces are oriented to secure said tube section in substantial alignment with the nostril of a patient, the improvement wherein said central part of the base has rear and front portions with said bearing surfaces being generally on said front portions, and wherein said spring means comprises a pair of similar spring members, each having an anchor with an arm extending from said anchor, said spring members positioned with their anchors adjacent and engaging each other, their arms each adjacent one of said bearing surfaces, and their anchors extending in the direction from rear to front in and secured to said central part, each of said arms resiliently movable between a first position closely adjacent one of said bearing surfaces and a second position spaced apart therefrom, said spring members being configured such that movement of the arms of a first of said spring members between its first and second positions induces a couple or pivoting force in said first spring member which is resisted by said second spring member due to the bearing contact of their anchors.
