Cross-shaped drainage pipe and mold and machining method for forming drainage pipe once

Abstract

The invention discloses a cross-shaped drainage pipe and a mold and machining method for forming the drainage pipe once. An open type cross-shaped groove type structural section is arranged on the tail section of the cross-shaped drainage pipe, so that the drainage pipe is not likely to be blocked by blood clots and blood buds, the extrusion resistance effect is achieved, and the drainage effect is good; when the drainage pipe is pulled out, the new blood bud tissue will be disengaged and drained along a channel, the drainage pipe can be easily pulled out, new muscle tissue damage is avoided, and no pain feeling is brought to patients. The middle closed type cross-shaped four-cavity structural section and the front circular pipe hollow structural section achieve the good drainage and liquid discharge effect. According to the mold for forming the drainage pipe once, the cross-shaped drainage pipe is formed once through difference combinations of a core rod, an outer loosing core and a cross-shaped inner loosing core. The machining processes are reduced, machining efficiency is improved and the cost is saved. The cross-shaped drainage pipe is applicable to the field of medical apparatuses and instruments.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cross drainage tube, a mold and a processing method for forming the drainage tube at one time. Background technique [0002] Drainage tube is a commonly used catheter in clinical practice. It is used to remove gas, digestive juice, peritoneal fluid, pus, incision exudate, etc. accumulated between human tissues or body cavities to the outside of the body in time to reduce pressure, eliminate dead space, and change infection. The microbiological environment of the site can inhibit the local bacterial reproduction, prevent the spread of infection, promote the resolution of inflammation, ensure the good healing of the wound site, and reduce the occurrence of complications. The drainage tube is generally made of silicone material, which is an elastic and soft material. When using the drainage tube, it is necessary to keep the drainage tube unobstructed and observe it at any time. It ...

AI Technical Summary

Problems solved by technology

[0003] At present, the structural drainage tubes with round holes and side holes are widely used, but the drainage effect is not good

The reason is that the general postoperative drainage time ranges from 2 to 15 days, and the round hole and side hole in the drainage tube are easily blocked by blood clots; Cover; the patient's wound is healing, new granulation will grow into the hole, causing drainage blockage; in the process of wound healing, it is easy to squeeze the traditional drainage tube, resulting in unsmooth drainage; after drainage, it grows into the hole The muscle tissue of the patient will hinder the extraction of the drainage tube. When the drainage tube is pulled out, it will cause new damage to the newly grown muscle tissue, and the patient will feel severe pain.
