Technical field
This utility model is related to a kind of medical apparatus and instruments, particularly a kind of intraperitoneal administration apparatus.
Background technology
Intraperitoneal administration is one kind of the common dosage regimen of intraperitoneal malignant tumor, and its principle is adopted infusion of medicine people
Or after the cavity beyond the gastrointestinal serosa of animal, within peritoneum, make medicine directly interact with Intraabdominal malignant tumor.
Compared with systemic administration scheme, intraperitoneal local makes the Drug exposure time of Intraabdominal tumor cell and high concentration using medicine
It is longer, absorb very fast, it is possible to increase the killing degree of drug on tumor cell, therapeutic effect are more preferable.
Two kinds of intraperitoneal administration modes of tube method and hard pin puncture method are put in prior art.Put tube method administration and easily cause abdominal cavity
Infection, hard pin puncture method can be avoided infection, but the status requirement to being administered is higher, need, when stomach wall is just passed through, to carry out
Injection.If not penetrating stomach wall just to be injected, medicine cannot be acted on and tumor cell, affect therapeutic effect；If paracentesis depth
It is too deep, then inferior epigastric artery, bladder, kidney or other internal organs are easily stabbed or damage, such as medicine once injects entrance
After the digestive system such as the intestines and stomach, it is impossible to the Intraabdominal malignant tumor of directly contact and produce corresponding curative effect, while can also aggravate to disappear
Change road toxicity, produce adverse consequencess.
In piercing process, hard pin is subject to resistance to hard pin puncture method always, and the position when resistance is reduced suddenly is as just worn
The administering position in saturating abdominal cavity, the position is optimal administering position, is come so that the sense that falls through is experienced in piercing process in actual therapeutic
Stomach wall is worn out in judgement, and this feel for relying primarily on doctor judges paracentesis depth and administering position, due to everyone sensation not
Together, therefore only feel to judge with human subjective, it is difficult to be accurately positioned optimal administering position, easily cause puncture muff
And intracorporeal organ is damaged, it is unstable to also result in therapeutic effect, and cure rate is reduced.
Utility model content
