An exhaust temperature measuring tube for hyperthermic perfusion therapy in the abdominal cavity

Abstract

The invention relates to an air exhausting and temperature measuring pipe for hyperthemal perfusion treatment of an abdominal cavity. The air exhausting and temperature measuring pipe comprises an air exhausting pipe body and a temperature detecting unit. The air exhausting pipe body comprises an inner pipe section stretching in the abdominal cavity and an outer pipe section located outside the abdominal cavity all the time. The inner pipe section is provided with an inflation air bag which surrounds the outer wall of the inner end of the inner pipe section. A side hoe is formed in the side wall of the inner end of the inner pipe section, and an inflation connector is arranged on the outer pipe section. The inflation connector is connected with the inflation air bag through an air pipeline located on the inner side of the air exhausting pipe body. The temperature detecting unit comprises a temperature sensing probe fixed to the inner end of the inner pipe section, and a temperature detecting display unit located outside the abdominal cavity, and the temperature detecting display unit and the temperature detecting probe are in signal connection. The air exhausting and temperature measuring pipe is novel in structure, low in cost, capable of monitoring the temperature of perfusate at any time, exhausting excessive air in the body cavity and observing whether the body cavity is filled of the perfusate, capable of improving the precision of treatment operation and achieving safety and repeatability, and capable of being widely used for clinical body cavity perfusion treatment.

Description

technical field [0001] The invention relates to a medical device for heat perfusion therapy, in particular to an exhaust temperature measuring tube for abdominal cavity heat perfusion therapy. Background technique [0002] Peritoneal hyperthermic perfusion therapy is a method that can effectively reduce postoperative implantation and metastasis in patients. It has a unique therapeutic effect on the prevention and treatment of implantation and metastasis caused by abdominal malignant tumors and the elimination of postoperative subclinical lesions. The treatment mechanism of intraperitoneal hyperthermic perfusion therapy is to use the sensitivity of tumor cells to temperature. At a specific temperature, tumor cells will be killed by high-concentration chemotherapy drugs while normal tissues will be less damaged. In addition, the heat-sensitizing effect of chemotherapy drugs , The perfusate mechanically flushes the free cancer cells. The specific method of body cavity hyperthe...

Problems solved by technology

In the actual heat perfusion treatment process, due to the lack of professional equipment, it is impossible to detect whether the gas in the airtight body cavity is not exhausted and whether the liquid is full, so that there may be dead space, which affects the effect of liquid perfusion therapy; in addition, heat perfusion The treatment requires high temperature control of the perfusion fluid, and the ability to accurately control the temperature of the fluid in the thoracic and abdominal cavity in real time is also a major problem for this treatment method.
