Description

The esophagus medicine is detained size applicator

This utility model relates to a kind of esophagus balling iron, particularly a kind of esophagus medicine is detained size applicator, (infiltration therapy) and medicine ion importing (electric conductance therapy) are soaked in the delay that is mainly used in after human body esophagus approach is offerd medicine, with the multiple disease at treatment esophagus and other position.It belongs to technical field of medical instruments.

Prior art has by the method for esophagus approach dispensing treatment esophagel disease: oral drugs, injectable drug and through three kinds of arteriae oesophageae intubate row drug infusions under the esophagoscope.Owing to can not stop in esophagus, medicine is difficult to the general action after performance local infiltration and the vein absorption behind the oral drugs.When esophagoscope was inserted, patient often was difficult to accept, and easily causes serious nausea and vomiting, can not use as conventional method.The arteriae oesophageae intubate drug-injection in treatment esophageal carcinoma, it is big to put the pipe operating difficulty, is difficult for successfully, and basic unit is difficult to promote.

The purpose of this utility model aims to provide a kind of simple, and eutherapeutic esophagus medicine is detained size applicator, to overcome weak point of the prior art.

Esophagus medicine by this purpose design is detained size applicator, comprise drug administration device and the injection catheter that is attached thereto, its architectural feature is to be penetrated with a draught line in the conduit, and the terminal intrinsic spongy body that is detained medicine of draught line, and spongy body is compressed inserts in the capsule for medicine that can swallow.Its operation principle is: to the treatment of the esophagus pathological changes such as the esophageal carcinoma, at first clarify a diagnosis through X line or esophagoscope, and definite lesion is apart from the degree of depth of front tooth.Regulate the degree of depth vernier on the injection catheter, patient's capsule for medicine of swallowing comes downwards to the vernier place, nibbles conduit with front tooth, and capsule dissolves in esophagus, and spongy body is opened, and expands and decreases the position in esophageal disease.The injection syringe needle connects the drug administration device install medicine, hangs on the crane that exceeds on patient's head, and the medicinal liquid injection catheter of just can flowing through slowly enters spongy body, soaks into pathological tissues.When during as the systemic disease beyond the dosing way treatment esophagus, spongy body being placed distal esophagus to esophagus, it is the abundantest therefore to locate venous plexus, and spongy body is detained medicine at this, soaks into absorption, and curative effect is better.

This utility model compared with prior art has following advantage:

1, volume is little, easily swallows, and vomiting reaction seldom takes place patient's no pain, and is easy and simple to handle.As long as know the degree of depth of lesion apart from front tooth, spongy body is placed lesion, medicine can soak into disease and decrease tissue, does not need to can be used as the conventional therapy means than high-tech and condition, and basic hospital all can use.

2, solve the problem that medicine can not be stagnated in esophagus, given full play to the effect of medicine topical therapeutic, especially better to esophageal wall pathological changes curative effect, can carry out the cancer therapy drug local infiltration as the esophageal carcinoma.The part medicine absorbs through esophageal veins and digestive tract, also can bring into play some general actions, because dosage is little, it is little that medicine is gone into blood volume, adds upper digestive tract and run off, so side effect is less.It has the function of esophagus balling iron, can treat multiple disease.

3, this product is a disposable product, and is simple in structure, makes easily, and the effect uniqueness has therapeutical effect local and whole body.

Accompanying drawing 1 is this utility model one example structure sketch map.

Fig. 2 is cylindrical cavernous structure sketch map.

Embodiment is described in further detail as follows in conjunction with the accompanying drawings:

One on No. 4 silk threads that are about 60cm are penetrated injection catheter 3, to form draught line 6, this line end is wrapped in the about 2cm of diameter, is about a cylindrical spongy body stage casing or the end of 3cm, can form cylindrical spongy body 1b, and the spongy body compression is placed capsule for medicine 2.As drug administration device, needle point inserts injection catheter 3, and with this fixed traction line 6, the top of injection tube is provided with suspension strap 8 with injection tube 7.Scale can be established in the surface of conduit 3, and with the big slightly sebific duct of a pipe nipple diameter as simple and easy degree of depth vernier 4.
