Abstract

An instrument for confirming the position of an indwelling gastrostomy catheter, and a method of confirming the indwelling position thereof, with which it is possible to reduce cleaning costs, and which does not cause any discomfort to a patient. An instrument for confirming the indwelling position of a gastrostomy catheter which is indwelling in a hole formed between the surface of the skin of the patient and the inner surface of the stomach wall comprising a fiberscope and a protective cover. Furthermore, the tip end of the protective cover comprises a light-transmissive window part and a wire that is linked to the outer periphery at the tip end of the protective cover.

Claims (4)

1. An instrument for confirming the position of an indwelling gastrostomy catheter which comprises a tubular part for running through a hole which is formed between the surface of the skin of a patient and the inner surface of the stomach wall, and extending from outside the patient's body to the inner surface of said stomach wall, and a stomach-internal fixed part which is capable of linking to a tip end of said tubular part and being arranged at the inner surface of said stomach wall, the fixed part having a through-hole adapted to receive the tubular part therethrough, said instrument for confirming the position of an indwelling gastrostomy catheter comprising a fiberscope, with which it is possible to observe the inner surface of the said stomach wall, adapted to run through the inside of said tubular part so that the tip end thereof projects from the through-hole of said stomach-internal fixed part, and a protective cover adapted to pass through said gastrostomy catheter together with said fiberscope, in a state in which said fiberscope is covered, the cover including a light-transmissive window part at a tip end thereof which allows observation of the inner surface of said stomach wall of said fiberscope.
2. An instrument for confirming the position of an indwelling gastrostomy catheter according to Claim 1, further comprising a linear member adapted to be linked to the outer periphery at the tip end of said protective cover, so that when the tip end of said protective cover is projecting from the through-hole of said stomach-internal fixed part, a tip end portion of said protective cover can be made to flex together with said fiberscope so that it is possible to change the observation direction of the fiberscope, by operation of a rear end portion of said linear member.
3. A method of confirming the position of an indwelling gastrostomy catheter which comprises a tubular part for running through a hole which is formed between the surface of the skin of a patient and the inner surface of the stomach wall, and extending from outside the patient's body to the inner surface of said stomach wall, and a stomach-internal fixed part capable of linking to a tip end of said tubular part and being arranged at the inner surface of said stomach wall, the fixed part having a through-hole adapted to receive the tubular part therethrough, said method of confirming the position of an indwelling gastrostomy catheter comprising:

making the gastrostomy catheter indwelling in said hole;
covering a fiberscope with a protective cover;
inserting said fiberscope covered by said protective cover inside said tubular part, with the tip end portion thereof projecting from the through-hole of said stomach-internal fixed part;

confirming the indwelling position, in which the inner surface of said stomach wall observed by means of said fiberscope is checked;

withdrawing the fiberscope covered by said protective cover from said gastrostomy catheter; and removing the protective cover from said fiberscope.
4. A method of confirming the position of an indwelling gastrostomy catheter according to Claim 3, in which a tip end of a linear member is linked to the outer periphery at the tip end of said protective cover, and in said step of confirming the indwelling position, the tip end portion of said protective cover can be made to flex together with said fiberscope so that it is possible to change the observation direction of the fiberscope, by operation of a rear end portion of said linear member.
