The opposite end of end head closed end is seal-connected with said bag body, said bag body is seal-connected with said connecting tube, the refluxing tube is positioned in the interior of cavity body formed after the end head, bag body and connecting tube are connected, its one end close to end head and bag body has at least one refluxing hole, the cooling liquor can be flowed into the described cavity body from opening end of connecting tube and can be flowed out from opening end of refluxing tube positioned in same end of opening end of said connecting tube. Said medical cooler can be mainly used for raising availability of radio frequency melting therapy.
Description
Technical field
The present invention relates to medical apparatus and instruments, be specifically related to a kind of medical cooler.
Background technology
Atrial fibrillation is a kind of common cardiac arrhythmia, as the term suggests be exactly atrial fibrillation, be chronic cardiac patient's a important complication at present, if atrial fibrillation is corrected in untimely treatment, blood is retarded by silt in the atrium, just easily form thrombosis, thrombosis comes off and flows to brain just to cause cerebral infarction easily be apoplexy.The treatment of atrial fibrillation is a global problem, and medication effect difference and side effect are many, and the surgical intervention wound is bigger, and what think tool prospect at present is intervention property radiofrequency ablation therapy.The principle of intervention property radiofrequency ablation therapy is to place electrode catheter to the chambers of the heart through femoral artery or femoral venous puncture, measure the position, place of the focus of cardiac arrhythmia by the X-ray subscript, reboot electrode catheter arrival focus it is carried out the radiofrequency ablation blocking-up, reach the ARR purpose of radical cure.Because during radiofrequency ablation therapy, can cause focus (treatment target spot) environment temperature sharply to raise, cause the heart thermal burn of human body on every side easily, according to statistics when coronary sinus vein is implemented the catheter ablation treatment, there is 75% operation can make esophagus produce thermal burn near the atrial walls place, also do not overcome the effective means of this defective of radiofrequency ablation therapy in the prior art, often can only take to shorten the radio-frequency (RF) therapy time method and avoid thermal burn, this just makes therapeutic effect have a greatly reduced quality.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of medical cooler, overcomes prior art causes the esophagus thermal burn at close atrial walls place easily when coronary sinus vein is implemented radiofrequency ablation therapy shortcoming.
The present invention adopts following technical scheme:
A kind of medical cooler, comprise the termination of end sealing, utricule, connecting tube, return duct and the liquid coolant of both ends open, the opposite end and the utricule of termination blind end are tightly connected, utricule and connecting tube are tightly connected, return duct is positioned at the inside that termination, utricule and connecting tube are connected the cavity of back formation, its end ring near termination and utricule is distributed with at least one return port around tube wall, liquid coolant flows into described cavity from the opening of connecting tube, flows out from the opening of the return duct of the same end of opening that is positioned at connecting tube.
The further optimization of described medical cooler is: the blind end of termination is made as the curved surface of rule.
The further optimization of described medical cooler is: bladder walls is made by soft material, after the injection liquid coolant, and bladder walls applying esophagus inwall.
The further optimization of described medical cooler is: the opposite end of termination blind end is provided with the protruding block that is used for fixing return duct, and it is from the outside or the inboard fixedly return duct of backflow tube wall.
The further optimization of described medical cooler is: the opening of connecting tube connects the logical diverter of the Y that comprises first isocon and second isocon, and return duct stretches out from second isocon.
The further optimization of described medical cooler is: first isocon connects the pump housing that is used to inject liquid coolant.
The further optimization of described medical cooler is: second isocon connects the adapter that is used for fixing return duct.
The further optimization of described medical cooler is: adapter connects the pump housing that is used to extract liquid coolant.
The further optimization of described medical cooler is: described soft material is made as high molecular polymer.
The further optimization of described medical cooler is: described liquid coolant is made as normal saline.
Technical scheme of the present invention produces to burn to the esophagus near the atrial walls place when avoiding carrying out radiofrequency ablation therapy provides effective chiller, therefore can prolong the time of radiofrequency ablation therapy greatly, reduce patient's misery, prevent to produce complication, thereby improved the effectiveness of radiofrequency ablation therapy.
Description of drawings
The present invention includes following accompanying drawing:
Fig. 1 is a medical cooler sketch map of the present invention;
Fig. 2 is a medical cooler cutaway view of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail:
As depicted in figs. 1 and 2, medical cooler of the present invention comprises the termination 1 of end sealing, the utricule 2 of both ends open, connecting tube 3, return duct 4 and liquid coolant, the opposite end and the utricule 2 of termination 1 blind end are tightly connected, utricule 2 is tightly connected with connecting tube 3, return duct 4 is positioned at termination 1, utricule 2 is connected the inside of the cavity of back formation with connecting tube 3, its end ring near termination 1 and utricule 2 is distributed with at least one return port 7 around tube wall, liquid coolant flows into described cavity from the opening of connecting tube 3, flows out from the opening of the return duct 4 of the same end of opening that is positioned at connecting tube 3.
Termination 1 blind end can be made as the curved surface of rule through further optimal design, and the sphere effect is better.The inside of termination 1 can be hollow or solid, and the opposite end of termination 1 blind end is provided with the protruding block that is used for fixing return duct 4, and it is from the outside or the inboard fixedly return duct 4 of backflow tube wall.
Bladder walls is made by soft material, after the injection liquid coolant, and bladder walls applying esophagus inwall.Utricule 2 is through further optimal design, and soft material can be made as high molecular polymer.
The opening of connecting tube 3 connects the logical diverter 5 of Y, return duct 4 stretches out from one of them isocon of the logical diverter 5 of Y, be provided for the fixedly adapter 6 of return duct 4 on this isocon, adapter 6 can further connect a pump housing that is used to extract liquid coolant.Another isocon of the logical diverter 5 of Y can insert the pump housing that is used to inject liquid coolant.
In actual applications, can use normal saline as liquid coolant.
Though pass through with reference to the preferred embodiments of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
