Catheter is designed for patients who can not normally urinate medical equipment, it is more complex to use, usually by professional health care personnel to operate, the specific use of the method of steps are as follows:
1, in the treatment room to open the catheterization kit with aseptic operation, ready to disinfect the goods.
2. Prepare the supplies, bring them to the patient, explain the purpose to obtain cooperation, and cover the patient appropriately.
3. Let the patient wash the vulva with soap and water. Those who can't take care of themselves will be assisted. Female patients wash the scope of the vestibule, labia major and minor and the surrounding skin; male patients, including the penis and foreskin, the foreskin should be turned over to remove the foreskin scale.
4, the health care personnel standing on the right side of the patient, the patient lying on his back, remove the pants and appropriate cover. The legs are bent at the knees and naturally adducted and separated, and the rubberized cloth and therapeutic towel are placed under the buttocks. The catheterization tray was placed between the knees, and the catheterization bag was opened.
5, with sterile tweezers clip disinfectant cotton balls, the first disinfection to the urethral opening as the center, from the outside to the inside, from the top to the bottom (the order of female patients is the pubic mound, vestibule, labia majora and minora, the urethral opening; male patients are the mound, scrotum, penis). The second disinfection was performed 1 time from the inside to the outside.
6, catheterization tray placed between the two knees, pouring disinfectant in a small medicine cup, with gloves, laying the hole towel, for intubation.
(1) female patients: with the left hand to separate and fix the labia minora, the right hand holding vascular clamp clamp disinfectant solution cotton balls and then disinfect the urethra once, and then clamp the catheter dipped in sterile liquid paraffin gently inserted into the urethra, the depth of insertion of about 4 to 6 cm or so, see the urine outflow, and then inserted into another 1 cm, the introduction of urine into the tray.
(2) male patients: a hand holding the penis, the other hand as described above disinfection will be inserted into the urethra catheter depth of about 20cm or so, see the urine outflow, and then inserted into the 2cm, with a curved tray to catch the urine. Tidy up the supplies and bed, record the amount and nature of urine.
Two, insert the catheter to pay attention to what matters
Catheter is into the body, the use of a number of matters to pay attention to, including:
1, the whole process requires strict aseptic operation to prevent urinary tract infection.
2, the insertion of the urinary catheter should be gentle, so as not to damage the mucosa of the urethra, if the insertion of a sense of obstruction can be replaced in the direction of the insertion of the urine outflow to see the insertion of 2cm, do not be too deep or too shallow, especially avoid repeated pumping of the urinary catheter.
3, choose the thickness of the catheter should be appropriate, for children or suspected urethral stenosis, the catheter should be thin.
4, the overfilled bladder, urination should be slow to avoid sudden decompression caused by bleeding or fainting.
5. When determining the residual urine, the patient should be instructed to urinate on his own and then catheterized. The amount of residual urine is usually 5-10 m. If it exceeds 100 ml, catheterization should be retained.
6, indwelling catheterization, should often check the urinary catheter fixation, whether there is no dislodgement, if necessary, with no Yin liquid to flush the bladder once a day; every 5-7 days to replace the urinary catheter, re-insertion should be allowed to let the urethra relax for a few hours, and then re-inserted.
Three, catheter is a single-use
Yes.
The catheter needs to be inserted into the human urethra, and for the sake of health, it is usually a single-use sterile catheter that will not be sterilized and then continue to be used, so as to avoid incomplete disinfection resulting in urinary tract infections and other related complications.
