Abstract

The utility model relates to a local chemotherapy pipe for esophagus cancer, which is an esophagus cancer local chemotherapy pipe with double gas bags and four cavities. The utility model is composed of a silica gel pipe with one sealed end and one opened end, and the silica gel pipe is provided with gas bags, an inflating pipes, a nutrition pipe and a medicine pushing pipe. The utility model used for local treatment can cause tumor tissue to be directly dipped in chemotherapy medicine and cause partial tumor tissue and oesophagus mucosae to absorb chemotherapy medicine, and the utility model can play a function that high concentration and high titer chemotherapy medicine kills cancer cells. Local medication has less side effect compared with whole body chemotherapy and can easily accepted by patients, the utility model doesn't impede the ingestion of nutrition at the same time, and the utility model can also match radiotherapy, thermotherapy and other treatment methods. The utility model has the advantages of simple operation, no contraindication and positive effect.

Description

Esophageal carcinoma local chemotherapy pipe

This utility model relates to a kind of medical pumping tool, specifically a kind of local chemotherapy pipe that is used for the treatment of esophageal carcinoma.

The treatment of esophageal carcinoma at present has operative treatment, systemic chemotherapy and radiotherapy, and after systemic chemotherapy is mainly used in operative treatment, this systemic chemotherapy is not suitable for the middle and advanced stage patient of operative treatment and cooperates radiocurable patient, also is not suitable for the treatment of recurrence after operation case, because the effect of paying of systemic chemotherapy is big, patient's general reaction and gastrointestinal reaction are big, patient is many can not to be accepted, and certainly, chemotherapeutics does not circulate by body effect, reach tumor by local, dose and concentration all do not cause tumor cell to be killed.

The purpose of this utility model is exactly the deficiency that exists in the prior art in order to overcome, solve the local chemotherapy problem of esophageal carcinoma, and provide a kind of simple to operate, make the chemotherapy effect of paying little, patient easily accepts, do not hinder the absorption of nutrition again, and can cooperate two air bags four chamber esophageal carcinoma local chemotherapy pipes of Therapeutic Method such as radiotherapy, thermotherapy.

This utility model is achieved in that it is to be made of the silica gel tube that an end seals an end opening, it is characterized in that, described silica gel tube is provided with two air bags, the respectively corresponding gas tube of each air bag, inlet end at gas tube is provided with seal valve, also be provided with between two gas tubes and push away pencil and nutritive canal, in local chemotherapy, inject focus by pushing away the medicinal liquid that pencil pushes by the hole that pushes away the pencil afterbody, the hyperalimentation diet that pushes by nutritive canal, hole nutritional solution by the nutritive canal afterbody enters gastric, can not influence the picked-up of nutrition because of local chemotherapy, and environment is unbalance in causing.

Esophageal carcinoma local chemotherapy pipe, when air bag is inflated 25ml by gas tube, the air bag diameter can reach 50mm.

Esophageal carcinoma local chemotherapy pipe is the injection section between two air bags, the injection section can be made 50mm, 70mm, three kinds of specifications of 100mm for selecting for use.

Be described in detail this utility model below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is a population structure sketch map of the present utility model;

Fig. 2 is the A-A cutaway view of this utility model Fig. 1;

Fig. 3 is the B-B cutaway view of this utility model Fig. 1;

Fig. 4 is the C-C cutaway view of this utility model Fig. 1;

Fig. 5 is that the D of this utility model Fig. 1 is to cutaway view;

Fig. 6 is a user mode sketch map of the present utility model.

As shown in Figure 1, two air bag four chamber esophageal carcinoma local chemotherapy pipes, be to constitute by the silica gel tube that an end seals an end opening, silica gel tube is provided with air bag 1 and air bag 2, air bag 1,2 respectively corresponding gas tubes 3, and the end of gas tube 3 is provided with sealing ring 4, between two gas tubes 3, be provided with and push away pencil 5 and nutritive canal 6, as Fig. 1, shown in Figure 3, medicinal liquid injects focus by the hole 7 that pushes away pencil 5 afterbodys, flows into gastric as Fig. 1, nutritional solution shown in Figure 4 by the hole 8 of nutritive canal 6 afterbodys.The application of esophageal carcinoma local chemotherapy pipe is identical with the method for slotting stomach tube, according to the magnitude range of focus and the treatment pipe of position selection different size, as pathological changes is 30mm, can select the esophageal carcinoma local chemotherapy pipe of 50mm; pathological changes is 50mm; can select the chemotherapy pipe of 70mm, pathological changes is 70-80mm, and focus can be selected the chemotherapy pipe of 100mm.It is suitable apart from the about 10mm of focus that the intubate rear gasbag places the upper and lower side of esophageal carcinoma diseased region, the degree of depth of determining to put pipe according to esophagoscope and the saturating lesion locations of barium, inflate behind the 10mm under when first air bag and (to inject in the also available contrast agent esophagus by lesions position, to help the location) with esophageall obstruetion, circulating with the normal blood fortune of not oppressing esophagus is purpose (each air bag is inflated 20m1 approximately), pushes away pencil certainly chemotherapeutics is pushed the esophagus that second airbag aeration blocks the focus epimere.The purpose of two balloon occlusion esophaguses is that the messenger drug liquid stream is not gone into gastric or the anti-oral cavity that flows into, tumor is immersed in the chemotherapeutics that high concentration, height tire, medicine by diseased region and mucosa absorption to reach the purpose of local chemotherapy, nutritive canal can be injected hyperalimentation diet, patient can not influence the picked-up of nutrition because of treatment in treatment, and environment is unbalance in causing.

This utility model is mainly used in the topical therapeutic of each phase of esophageal carcinoma, be used for the hemorrhage hemostasis by compression of breaking of esophageal carcinoma diseased region and esophageal varix, provisions etc. is blocked in the fistula compressing that also can be used for esophagus thoracic cavity fistula, adopt topical therapeutic of the present utility model directly to be immersed in tumor tissues in the chemotherapeutics, tumor tissues part and mucous membrane of esophagus are absorbed, to play high concentration, the effect of the chemotherapeutics kill cancer cell that height is tired, local application is little than the systemic chemotherapy effect of paying, patient easily accepts, do not hinder the absorption of nutrition again, also can cooperate radiotherapy, Therapeutic Method such as thermotherapy improve curative effect.Local chemotherapy also can make focus dwindle, and provides condition to operative treatment, and this utility model is simple to operate, no contraindication, and effect is sure, is worthy to be popularized.
