Abstract
The apparatus comprises a T-shaped member adapted to be inserted into the mouth of a patient and feeding oxygen thereto. The T-shaped member is divided into front and rear portions by an apertured wall into which a catheter assembly is to be inserted for insertion into a patient. The aperture in the wall is controlled by a rotary rod or valve having a through-hole which can be aligned with the aperture in the wall in one position and which is out of alignment with the wall in another position.
Claims10
Medical apparatus comprising a closed system for providing oxygen and suction to a patient including
- a tubular member having a front patient portion and a rear portion, said rear portion having a front end and a rear end,
- a first wall disposed between said front patient portion and said front end of said rear portion, said first wall having a front surface and a rear surface,
- a hole in said first wall,
- a second wall at said rear end of said rear portion closing off said rear portion of said tubular member, said second wall having means for permitting a catheter to enter and leave said tubular member,
- an auxiliary tubular member coupled to said front patient portion for providing treatment means to a patient,
- a valve member comprising a rod having a through-hole rotatably mounted in said rear portion of said tubular member closely adjacent to said rear surface of said first wall and in fluid tight engagement therewith,
- a through-hole in said valve member, said through-hole being aligned with said hole in said first wall in one position of said valve member to permit a catheter to pass through and said through-hole being out of alignment with said hole in said first wall in another position of said valve member, said valve member providing a leakproof block of said hole in said wall when said valve member is in said another position,
- means coupled to said second wall of said rear portion of said tubular member for inserting a catheter therein and into said tubular member and for removing a catheter after it has been withdrawn from a patient through said front portion of said tubular member, and
- means coupled to said rear portion of said tubular member for admitting a washing fluid into said rear portion and for washing a catheter after it has been withdrawn from a patient,
- said first wall and said valve member and said second wall forming a relatively fluid tight washing chamber for said tubular member.
A closed system for treating a patient with suction and oxygen and other medication comprising
- a T-shaped tubular member having a front patient portion and a rear portion for supplying oxygen and suction and medication to a patient,
- a wall having an aperture separating said front patient portion from said rear portion of said tubular member,
- means providing a generally leak-proof washing chamber in said rear end of said tubular member in leak-proof contact with said apertured wall,
- said means including a rotatable valve comprising a rod having a through-hole which, in one position of said valve is in alignment with said hole in said wall and permits communication between said front patient portion and said rear portion of said tubular member, and in another position of said valve, is out of alignment with said hole in said wall whereby said front patient portion is blocked from said rear portion and
- means coupled to said rear portion of said tubular member providing a controlled supply of oxygen, suction and medication to said T-shaped member and a patient.
