Technical Field

[0001] The utility model relates to the technical field of medical auxiliary devices, in particular to an epidural catheter fixing device used for painless delivery. Background Art

[0002] In clinical practice, one of the commonly used painless delivery techniques is spinal blockade, which involves inserting an epidural catheter into the epidural space at the waist of the parturient and using it in conjunction with an analgesic pump to relieve the pain of the pregnant woman. In this case, a fixation device is needed to fix the epidural catheter to the patient's skin to prevent it from falling off.

[0003] After searching, the utility model discloses an anti-falling epidural catheter fixer for painless delivery with announcement number CN211724342U, comprising a flexible base, an upper surface wall of which is fixed a first fixing block and a second fixing block, the second fixing block being located on one side of the first fixing block, the upper surface wall of the first fixing block being provided with a first tube clamping groove, and the upper surface wall of the second fixing block being provided with second tube clamping grooves at equal intervals. The utility model can pass the epidural catheter through the second tube clamping groove in sequence through the cooperation of the first fixing block, the first tube clamping groove, the second fixing block and the second tube clamping groove, and then pass the epidural catheter near the waist of the pregnant woman through the first tube clamping groove, which can effectively improve the orderliness and stability of the fixation of the epidural catheter and effectively avoid the bending of the epidural catheter. In addition, the stability of the fixed epidural catheter can be further improved through the cooperation of the insertion rod, the slot and the baffle.

[0004] Based on the above patent, through the cooperation of the first fixing block, the first tube clamping groove, the second fixing block and the second tube clamping groove, the epidural catheter can be passed through the second tube clamping groove in sequence, and then the epidural catheter close to the waist of the pregnant woman can be passed through the first tube clamping groove, which can effectively improve the orderliness and stability of the fixation of the epidural catheter and effectively avoid the bending of the epidural catheter. In addition, through the cooperation of the insertion rod, the slot and the baffle, the stability of the fixed external catheter can be further improved.
