Gas Supply System

Abstract

A gas supply system is disclosed. The gas supply system includes a housing, a spool, a gas tube, at least one opening, a retract mechanism and a holding member. The spool is configured within the housing. The gas tube is retractably wound on the spool and includes a first end portion and a second end portion capable of being connected to a gas supply and a nasal cannula respectively. The at least one opening is configured on the housing for enabling at least one of the first end portion and the second end portion of the gas tube to extend out of the housing. The retract mechanism is configured in the housing and is capable of retracting a portion of the gas tube extended out of the housing. The holding member extends from the housing and enables the gas supply system to be removably mounted on a supporting member.

1 . A gas supply system for delivery of gas from a gas supply to a nasal cannula and capable of being removably mounted on a supporting member, the gas supply system comprising:
 a housing;   a spool configured within the housing and rotatably coupled to the housing;   a gas tube retractably wound on the spool, the gas tube having a first end portion and a second end portion, the first end portion of the gas tube capable of being connected to the gas supply, and the second end portion of the gas tube capable of being connected to the nasal cannula;   at least one opening configured on the housing for enabling at least one of the first end portion and the second end portion of the gas tube to extend out of the housing;   a retract mechanism configured in the housing and operatively coupled to the spool, the retract mechanism capable of retracting a portion of the gas tube extended out of the housing; and   a holding member extending from the housing, the holding member enabling the gas supply system to be removably mounted on the supporting member.   
     
     
         2 . The gas supply system of  claim 1 , wherein the housing comprises:
 a first wall;   a second wall substantially parallel to the first wall; and   at least one peripheral wall extending between the first wall, and the second wall forming a cavity therebetween.   
     
     
         3 . The gas supply system of  claim 2 , wherein the at least one peripheral wall is at least partially openable for enabling an access to the cavity of the housing. 
     
     
         4 . The gas supply system of  claim 1 , wherein the housing is made of a transparent material. 
     
     
         5 . The gas supply system of  claim 1 , wherein the housing is made of a plastic material. 
     
     
         6 . The gas supply system of  claim 1 , wherein the spool is removably coupled to the housing. 
     
     
         7 . The gas supply system of  claim 1 , wherein the gas tube is made of a plastic material. 
     
     
         8 . The gas supply system of  claim 1 , further comprising a swivel mechanism operably coupled to an end of the holding member, the swivel mechanism capable of enabling the gas supply system to rotatably move upon being mounted on the supporting member. 
     
     
         9 . The gas supply system of  claim 1 , further comprising a retaining mechanism slidably engaged with the portion of the gas tube extended out of the housing, the retaining mechanism capable of retaining the extended portion of the gas tube outside the housing.
