Description

A transanal intestinal obstruction catheter kit

technical field

The utility model relates to the technical field of medical devices, in particular to a transanal intestinal obstruction catheter kit.

Background technique

Intestinal Obstruction Catheter Kit is a medical device used to treat intestinal obstruction in surgical acute abdomen. There are many causes and types of intestinal obstruction. After the onset, it can not only cause local changes in the intestinal tract, but also cause systemic pathological changes. Therefore, for patients with intestinal obstruction, the site of intestinal obstruction must be decompressed and drained in time to reduce the pressure at the site of obstruction.

Although the nasally inserted intestinal obstruction catheter can solve most patients with intestinal obstruction, for the obstruction of the colon, especially the obstruction of the left colon, because the obstructive position is too deep, the insertion of the catheter through the nose will take a long time. Intestinal obstruction catheter can not achieve good decompression effect in time, which increases the risk of emergency surgery for patients. The transanal ileus catheter kit is inserted through the anus, which can reach the lower part of the colon obstruction more quickly, and with the guide wire and dilation tube, the catheter can pass through the obstruction part and reach the upper part, which can achieve a good decompression effect, so that the doctor can fully preoperative examination, turning emergency surgery into elective surgery. While reducing the pain of the patient, it also reduces the risk of surgery.

For example, a Chinese patent discloses a device for preventing blockage of a transanal intestinal obstruction catheter, patent number: CN202011620712.5. In this comparison document, the device for preventing blockage and dredging can realize the dredging of the catheter body without serious blockage, and can also Detect the blockage in the catheter body, and effectively judge whether the catheter body is unblocked. Compared with manual bending and squeezing of the catheter, the labor workload of personnel is greatly reduced, and the judgment of blockage removal is more accurate, which is convenient for personnel to use. To ensure the smooth progress of drug perfusion and drainage, the above-mentioned device is not equipped with a structure to penetrate and expand the contents of intestinal obstruction during use, and the diversion and flushing structure is difficult to reach the upper part of the obstruction site in a short time, which is not conducive to improving the treatment process. Operational efficiency.

To this end, we propose a transanal ileus catheter kit.
