Embodiment 1

[0044] Such as figure 1 Shown is the drainage tube and temperature measuring devices used in the prior art for thermal perfusion. The drainage tube 2 guides the chemotherapy liquid into and pumps out of the body cavity 3 , and the power is provided by the pump 4 . The temperature-measuring sensor 1 in the figure is set in the in-body pipe and the out-flow pipe to monitor the temperature before and after entering the body cavity respectively. Due to the temperature difference between the chemotherapy liquid and the external environment, it is inevitable that the measured temperature does not match the actual treatment temperature, and the temperature control device cannot be adjusted accurately, which affects the chemotherapy effect. Such as figure 2 As shown, the temperature measuring wire 2 in the temperature measuring sensor 1 is shown, which cannot monitor the temperature parameters in the treatment process in real time, accurately and effectively, and cannot achieve the ...

Embodiment 2

[0056] This embodiment provides another heat perfusion direct temperature measurement drainage tube set, such as image 3 As shown, a thermal perfusion direct temperature measurement drainage tube set includes a double-headed drainage tube 1 of unequal length and a fixing part 2, which is used to fix the device and ensure the stability of the treatment during use; the drainage channel 3 is used Used for circulation of therapeutic liquid, lumen wall sheath 4, temperature measuring wire 5 for installing temperature measuring sensor, joint 6, joint 7 which serve as connection structure with the heat perfusion machine.

[0057] In order to further ensure the therapeutic effect, a plurality of circular drainage holes are set on the side wall of the drainage channel 3 of the thermal perfusion direct temperature measurement drainage tube kit. The diameter of the drainage holes is 2mm, which can provide a circulation channel for the treatment liquid and prevent blockage and other poor ...

Embodiment 3

[0059] This embodiment provides another thermal perfusion direct temperature measurement drainage tube set. In order to further ensure the therapeutic effect, a plurality of oval drainage holes are set on the side wall of the drainage channel 3 of the thermal perfusion direct temperature measurement drainage tube set, which is as long as the drainage tube. The axes are parallel, the major axis of the ellipse is 3 mm, and the minor axis is 2 mm. The distribution of drainage holes occupies about 50mm of the end of the drainage tube set. It is set in an oval shape, which can make the treatment liquid flow smoothly, effectively solve the technical problem of poor circulation, and achieve a good treatment effect.

Abstract

The invention discloses a combined hyperthermic perfusion drainage tube set and belongs to the field of medical apparatuses and instruments. The hyperthermic perfusion drainage tube set is divided into a drainage tube set body and a temperature measurement set, wherein an outer set is directly fixed to the center of a heparin cap film by using a temperature measurement wire, a disposable sterile temperature measurement sensor is inserted into a drainage tube wall sheath during treatment, a heparin cap is fixed, an external connector is directly connected with a hyperthermic perfusion machine,and the set can be directly removed after treatment. The drainage tube set is provided with a special temperature measurement sensor drainage tube wall sheath channel, original in-vitro indirect temperature measurement is changed into in-vivo direct temperature measurement for hyperthermic perfusion of the body cavity, the precision of temperature measurement in the body cavity during treatment inthe body cavity is greatly improved, and especially the influence of outside environment temperature on temperature measurement is completely eradicated, so that medical workers accurately master temperature change of the body cavity. The combined hyperthermic perfusion drainage tube set is simple in whole structure, easy to manufacture, low in cost and convenient to popularize widely.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an accurate temperature-measuring drainage tube set for advanced malignant tumor body cavity effusion hyperthermia perfusion treatment. Background technique [0002] As we all know, advanced tumor metastasis to the pleura and peritoneum leads to malignant pleural effusion. Body cavity hyperthermic perfusion chemotherapy is the most important and main treatment method to control malignant effusion. The accuracy of temperature control often determines the treatment effect of patients and the risk of serious complications. Appear. If the temperature is too low, it can neither increase the concentration of chemotherapy drugs in tumor cells nor cause tumor cell apoptosis; if the temperature is too high, it will cause tissue burns in the patient's body cavity, short-term side effects will cause pain in patients, and long-term side effects will cause tissue fibrosis in the body ...
