The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of hot perfusion chemotherapeutic apparatus is provided, it can realize perfusion solution closed circulation between human abdominal cavity and device, the heat that loses in the perfusion can constantly obtain to replenish, and the temperature of perfusion solution can accurately be controlled at required treatment temperature (42～43 ℃).
This utility model adopts following technical scheme: it comprises casing, storage liquid container, medicinal liquid carrier pipe, heat-exchange device, adjustable extruding charge pump; Described storage liquid container bottom is provided with the outflow interface, the top is provided with lid; Described adjustable extruding charge pump is serially connected with on the medicinal liquid carrier pipe of setting up heat-exchange device and with the storage liquid container and is connected; Described heat-exchange device comprises heat exchange tank, heat-exchange tube, heater and pump, heater is provided with water inlet pipe and the outlet pipe that constitutes water-flow circuit with the heat exchange tank jointly, pump is serially connected with on the outlet pipe, and heat-exchange tube coiling dipping bath is in the heat exchange tank; Described storage liquid container is provided with circulation medicinal liquid reflux inlet and drainage screen; Described medicinal liquid carrier pipe is provided with attemperator, comprise the medicinal liquid exterior coating of pipe line pipe of being located at the outer outfan of casing and the insulation water jacket that is positioned at two ligaments, described trocar sheath two ends are provided with insulation water inlet and outlet, described inlet divides support interface to be connected by a set trident of the pipeline and the outlet pipe of heater, and described outlet is connected with the heat exchange tank with pipeline.
As improvement of the present utility model, described drainage screen aperture is 40～75 microns.
As further improvement of the utility model, the medicinal liquid carrier pipe proximal end of the outer outfan of casing is provided with the temperature pressure sensing probe.
This utility model has following advantage:
One, owing to infusion liquid closed circulation between abdominal cavity and heat-exchange device, the heat that loses in the perfusion can constantly obtain to replenish, and the temperature of perfusion solution can accurately be controlled at required treatment temperature (42～43 ℃);
Two, can under the situation that does not reduce the infusion liquid temperature, guarantee enough infusion times (60～120 minutes);
Three, infusion liquid recycles, and does not increase its use amount because of infusion time prolongs, and has saved medical expense;
Four, infusion liquid recycles, and can guarantee the enough medicinal liquid amounts of pouring into of intraperitoneal (2500～3000 milliliters), avoids intraperitoneal to have heat perfusion " dead space ", thereby can obtain ideal curative effect;
Five, the perfusion solution of closed circulation is difficult for contaminatedly, is difficult for causing the abdominal cavity secondary infection, and in addition, the medicinal liquid carrier pipe (containing heat-exchange tube) of setting up attemperator can be made into disposable special product, can cross infection between the different patients;
Six, by placing the intraperitoneal perfusion pipeline in the art, postoperative can repeatedly be implemented hyperthermic perfusion chemotherapy to the abdominal cavity, and curative effect is better;
Seven, this device also has characteristics such as safe and reliable, that precision is high, automaticity is high, and is easy and simple to handle.
Below in conjunction with embodiment this utility model is described in further detail.
