Description
Technical field
This utility model relates to a kind of local chemotherapy device for esophageal cancer, belongs to technical field of medical instruments.
Background technology
The traditional remedies of esophageal carcinoma is intravenous chemotherapy, and adopting the method is to make medicine bring into play curative effect in the cyclic process of blood.Its weak point is that side effect is large, in addition because medicine does not directly contact with lesions position, therefore curative effect is undesirable.
Chinese patent Granted publication CN2834605Y, it discloses a kind of local chemotherpay tube for esophagus cancer, and it comprises medicine-pouring pipe, skeleton conduit and with upper sacculus and the lower sacculus of breather, the body of skeleton conduit passes from upper and lower sacculus; Medicine-pouring pipe is through upper sacculus, and its port of export is between upper sacculus and lower sacculus.Its objective is that providing a kind of directly implements the device of chemotherapy to esophageal carcinoma affected area for medicinal liquid, its weak point is that this chemotherapeutic instrument adopts room temperature medicinal liquid filling, does not take measure that medicinal liquid is heated, to improve curative effect.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of local chemotherapy device for esophageal cancer of taking medicinal liquid to heat measure is provided.
For achieving the above object, this utility model adopts following technical proposals:
A local chemotherapy device for esophageal cancer, it comprises medicine-pouring pipe, skeleton conduit and with upper sacculus and the lower sacculus of breather, the body of skeleton conduit passes from upper and lower sacculus; Medicine-pouring pipe is through upper sacculus, and its port of export is between upper sacculus and lower sacculus, and it also comprises that end is provided with the thermometric pipeline of temperature element, and this thermometric pipeline is through upper sacculus, and its temperature element is between upper sacculus and lower sacculus; In described skeleton conduit, be provided with heating; The outside of described skeleton conduit is also provided with controller, and described temperature element is all connected with this controller with heating.
Described heating is Electric radiant Heating Film or the heating wire investing on skeleton pipe inner wall.
Described temperature element is electroheat pair.
Skeleton conduit is for making by material bending and that have certain degree of hardness.
Described controller can mainly be comprised of single-chip microcomputer, existing in prior art, principle can be: by thermocouple (being temperature element), platinum resistance equitemperature sensing device, temperature signal is transformed into the signal of telecommunication, by circuit control relays such as single-chip microcomputer, PLC, makes heating (or refrigeration) equipment work (or stopping).
Local chemotherapy device for esophageal cancer provided by the utility model is to improve and form on the basis of former local chemotherpay tube for esophagus cancer, owing to setting up heating in skeleton conduit, can when chemotherapy, to the medicinal liquid being poured between upper and lower two sacculus, heat; And temperature element can be measured the temperature of medicinal liquid by wire, feed back the controller in skeleton conduit outside, if at the bottom of measured temperature in the lower limit of the scope of preset temperature, heating heating, similarly, if measured temperature is higher than the upper limit of the scope of preset temperature, heating stops heating, maintains the temperature of perfusion solution in certain limit.
Normal tissue cell can tolerate 47 ℃ of lasting 1h under hot conditions, and malignant cell only can tolerate 43 ℃ of lasting 1h, therefore according to the principle of hyperthermic perfusion chemotherapy, its temperature of device of the present utility model can be set in 45-47 ℃, can guarantee that the temperature of medicinal liquid maintains between 43-47 ℃.Meanwhile, in clinical, this device also can coordinate radio-frequency (RF) thermotherapeutic machine to treat suffering from the patient of esophageal carcinoma, and unique kind of method not.
This utility model is reasonable in design, and features simple structure can effectively improve the kill rate of chemotherapy to esophageal carcinoma, can make again thermotherapy and chemotherapy treat esophageal carcinoma simultaneously, and with respect to original single therapy, effect is more obvious.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
1. medicine-pouring pipes wherein, 2. skeleton conduit, 3. breather, 4. goes up sacculus, 5. descends sacculus, 6. thermometric pipeline, 7. temperature element, 8. heating.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further illustrated.
A local chemotherapy device for esophageal cancer, please refer to Fig. 1, and it comprises medicine-pouring pipe 1, skeleton conduit 2 and with upper sacculus 4 and the lower sacculus 5 of breather 3, the body of skeleton conduit 2 passes from upper and lower sacculus; Medicine-pouring pipe 1 is through upper sacculus 4, and its port of export is between upper sacculus 4 and lower sacculus 5, and it also comprises that end is provided with the thermometric pipeline 6 of temperature element 7, and this thermometric pipeline 6 is through upper sacculus 4, and its temperature element 7 is between upper sacculus 4 and lower sacculus 5; In described skeleton conduit 2, be provided with heating 8; Described temperature element 7 is all connected with the controller of skeleton conduit 2 outsides with heating 8, and controller is connected with power supply.
In present embodiment, described heating is Electric radiant Heating Film or the heating wire investing on skeleton pipe inner wall, and described temperature element is electroheat pair.Consider that heating and temperature element are for the relevant routine techniques that relates to industrial circles such as " temperature controls ", will not be in detail in this description and embodiment, in Practical manufacturing application process, as long as play electrical heating and thermometric effect, all can realize the goal of the invention of this patent.
During chemotherapy, first skeleton conduit 2 is inserted by mouth or nasal cavity, enter intraesophageal appropriate location, it should be noted that this skeleton conduit 2 is for making by material bending and that have certain degree of hardness.Then, injecting gas or liquid make sacculus 4 and lower sacculus 5 make it to expand, and make it to be fixed on the upper and lower side of tumor focus, and are close in esophageal wall.Afterwards, by medicine-pouring pipe 1, to lesions position, supply medicinal liquid.Turn on the power switch, the controller of having established in advance temperature range is connected with heating 8 and temperature element 7, and controls the temperature of medicinal liquid.This device can effectively improve the kill rate of chemotherapy to esophageal carcinoma, can make again thermotherapy and chemotherapy treat esophageal carcinoma simultaneously, and therapeutic effect is better.
