Abstract
Abstract A medical instrument for positioning an elongated sac or catheter in a pathient''s urethra for urinary drainage or bacterial sampling. The elongated sac fits in a bore of a flexible insertion tube. One end of the sac extends from a front end of this tube and is secured to a rigid tubular guide sleeve encircling a portion of the flexible introducer tube. As the flexible insertion tube is pushed forward, the insertion tube extends out of the guide sleeve into the urethra and the sac rolls out over a front end of the insertion tube into contact with the urethra.

A medical instrument for everting an elongated sac and inserting it into a body orifice, said instrument comprising: a flexible insertion tube having a forward and rearward end; an elongated tubular sac within a bore of the insertion tube, one end portion of the sac being removably disposed in the bore and extending over the forward end of the inserting tube; an elongated, rigid guide sleeve substantially longer than the insertion tube diameter and reciprocably embracing a forward section of the insertion tube adjacent the insertion tube''s forward end, said guide sleeve including abutment means at the forward distal end for preventing the guide sleeve from entering a body opening, said tubular guide sleeve keeping the forward section of the insertion tube from laterally bending before and as it enters a body orifice, said sac''s other end portion being reversibly secured to rearwardly of the forward distal end of the tubular guide sleeve, the insertion tube being of such a character than when longitudinal force is applied thereon rearward of the forward distal end of the rigid guide sleeve, the insertion tube is urgeD longitudinally along the bore of the tubular guide sleeve and pushes the forward end of the insertion tube out of the tubular guide sleeve beyond the distal end thereof, thereafter pulling the sac out of the insertion tube''s bore, turning the sac inside out on the outer surface of the insertion tube and laying it down along an inside surface of the body orifice.
Claim 2
Dependent Claim
248 words
A medical instrument for everting an elongated sac and inserting it into a body orifice, said instrument comprising: a flexible insertion tube having a forward and rearward end; an elongated tubular sac within a bore of the insertion tube, one end portion of the sac being removably disposed in the bore and extending over the forward end of the inserting tube; an elongated, rigid guide sleeve substantially longer than the insertion tube diameter and reciprocably embracing a forward section of the insertion tube adjacent the insertion tube''s forward end, said guide sleeve including abutment means at the forward distal end for preventing the guide sleeve from entering a body opening, said tubular guide sleeve keeping the forward section of the insertion tube from laterally bending before and as it enters a body orifice, said sac''s other end portion being reversibly secured to rearwardly of the forward distal end of the tubular guide sleeve, the insertion tube being of such a character than when longitudinal force is applied thereon rearward of the forward distal end of the rigid guide sleeve, the insertion tube is urgeD longitudinally along the bore of the tubular guide sleeve and pushes the forward end of the insertion tube out of the tubular guide sleeve beyond the distal end thereof, thereafter pulling the sac out of the insertion tube''s bore, turning the sac inside out on the outer surface of the insertion tube and laying it down along an inside surface of the body orifice.
Claim 3
Dependent Claim
27 words
A medical instrument as set forth in claim 1 wherein the instrument has means connected to the insertion tube for urging it longitudinally along the guide sleeve.
Claim 4
Dependent Claim
223 words
A medical instrument for everting an elongated sac and inserting it into a body orifice, said instrument comprising: a flexible insertion tube having a forward and rearward end; an elongated tubular sac within a bore of the insertion tube, an end portion of the sac extending from the forward end of the insertion tube; an elongated, rigid tubular guide sleeve encircling a section of the insertion tube adjacent the insertion tube''s forward end, which tubular guide sleeve keeps this section of the insertion tube from laterally bending before entering a body orifice, said sac''s end portion being secured to this tubular guide sleeve, whereby the insertion tube can be urged longitudinally along an inside of the tubular guide sleeve to push the forward end of the insertion tube out of the tubular guide sleeve, thus pulling the sac out of the insertion tube''s bore, turning the sac inside out on an outer surface of the insertion tube and laying it down along an inside surface of a body orifice, the instrument having means connected to the insertion tube for urging it longitudinally along the guide sleeve, the guide sleeve having at least one longitudinal slot and the means for urging the insertion tube along the guide sleeve is a rigid handle attached to the insertion tube and extending outwardly through the longitudinal slot.
Claim 5
Dependent Claim
223 words
A medical instrument for everting an elongated sac and inserting it into a body orifice, said instrument comprising: a flexible insertion tube having a forward and rearward end; an elongated tubular sac within a bore of the insertion tube, an end portion of the sac extending from the forward end of the insertion tube; an elongated, rigid tubular guide sleeve encircling a section of the insertion tube adjacent the insertion tube''s forward end, which tubular guide sleeve keeps this section of the insertion tube from laterally bending before entering a body orifice, said sac''s end portion being secured to this tubular guide sleeve, whereby the insertion tube can be urged longitudinally along an inside of the tubular guide sleeve to push the forward end of the insertion tube out of the tubular guide sleeve, thus pulling the sac out of the insertion tube''s bore, turning the sac inside out on an outer surface of the insertion tube and laying it down along an inside surface of a body orifice, the instrument having means connected to the insertion tube for urging it longitudinally along the guide sleeve, the guide sleeve having at least one longitudinal slot and the means for urging the insertion tube along the guide sleeve is a rigid handle attached to the insertion tube and extending outwardly through the longitudinal slot.
Claim 6
Dependent Claim
23 words
A medical instrument as set forth in claim 3 wherein the handle includes a rigid C-shaped tube segment fitting over the insertion tube.
Claim 7
Dependent Claim
59 words
A medical instrument as set forth in claim 1 wherein the guide sleeve has a pair of diametrically opposed longitudinal slots and the instrument has a handle with a rigid C-shaped tube segment fitting over the insertion tube, said handle also having a pair of integrally attached diametrically opposed thumb pads which extend outwardly through the two elongated slots.
Claim 8
Dependent Claim
