Abstract

The utility model relates to an airway dilation balloon catheter under a bronchoscope. The airway dilation balloon catheter under the bronchoscope comprises a guide wire tube, an inner catheter, an outer airway tube and a balloon, wherein the inner catheter is arranged outside the guide wire tube; the outer airway tube is arranged outside the inner catheter; the balloon is communicated with the outer airway tube; a plurality of flexible supporting soft strips are connected between the guide wire tube and the inner catheter; lattices convex strips are arranged on the outer surface of the balloon; the lattices convex strips and the balloon adopt an integrated structure. According to the airway dilation balloon catheter under the bronchoscope, the lattices convex strips are arranged on the outer surface of the balloon, and the balloon and a lesion part form certain friction during balloon dilation, so that a malposition phenomenon of the balloon and the lesion part is avoided; the balloon is made from a fluorine-containing antibacterial material, so an infection phenomenon is avoided when the balloon contacts with the lesion part.

Description

Expansion air flue foley's tube under a kind of bronchoscope

Technical field

This utility model relates to the field of medical apparatus and instruments, expansion air flue foley's tube under especially a kind of bronchoscope.

Background technology

Airway constriction is the common complication of endobronchial tuberculosis, and limitation of activity, tachypnea, dyspnea can appear in the patient clinically, causes labour force's forfeiture, also can cause narrow far-end recurrent pulmonary infection.Bronchial lumen intervenien therapy airway constriction is a new technique of in recent years carrying out, and makes many some air flue intracavity lesions that need operative treatment or can't treat in addition, can obtain satisfactory effect by interventional therapy under bronchoscope.Through bronchus mediation balloon expandable, control the airway constriction that the optimum air flue intracavity disease of art treatment causes and can improve patient's ventilatory function obstacle.

The air flue foley's tube outer surface used at present is coated with hydrophilic coating, this hydrophilic coating can improve trafficability characteristic and the passing through property of pathological changes of foley's tube, but because this hydrophilic coating possesses superslide, in the process of balloon expandable, easily cause the dislocation of sacculus, thereby cause the inaccuracy of balloon expandable and do not possess antibiotic purpose.

Summary of the invention

The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide under a kind of bronchoscope expansion air flue foley's tube, its project organization rationally, can avoid misplacing and reaching antibiotic purpose.

The technical scheme that its technical problem that solves this utility model adopts is: expansion air flue foley's tube under a kind of bronchoscope, comprise wire leading pipe, be located at the inner catheter of wire leading pipe outside and be located at the outer airway of inner catheter outside and the sacculus be connected with outer airway, between described wire leading pipe and inner catheter, be connected with soft of some flexible support, described sacculus outer surface is provided with latticed raised line, and latticed raised line and sacculus are integral structures.

In order to realize antibiotic purpose, to avoid producing and infect phenomenon, the material of described sacculus is that fluorine-containing anti-biotic material is made.

For can be easily manufactured, to realize one-body moldedly, described outer airway and sacculus are integral structures.

The beneficial effects of the utility model are: expansion air flue foley's tube under described a kind of bronchoscope, adopt latticed raised line to be located on the sacculus outer surface, when utilizing air bag expansion, certain friction be can make between sacculus and lesion to reach, thereby sacculus and lesion generation inconsistent phenomenon avoided; Adopt the principle of fluorine-containing antimicrobial form material as sacculus, phenomenon occurs to infect in the time of can avoiding sacculus contact lesion.

The accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Fig. 1 is the overall structure schematic diagram of expansion air flue foley's tube under a kind of bronchoscope described in the utility model;

Fig. 2 is wire leading pipe and transverse cross-sectional view after inner catheter is connected in Fig. 1.

Accompanying drawing acceptance of the bid score state as follows: 1, wire leading pipe, 2, inner catheter, 3, outer airway, 4, sacculus, 5, soft of flexible support, 6, latticed raised line.

The specific embodiment

By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with this utility model.

Expansion air flue foley's tube under a kind of bronchoscope as shown in Figure 1, comprise wire leading pipe 1, in wire leading pipe 1 outside, be provided with inner catheter 2, in inner catheter 2 outsides, be provided with outer airway 3, outer airway 3 is connected with sacculus 4, and outer airway 3 and sacculus 4 are structure as a whole, and on sacculus 4 outer surfaces, is provided with latticed raised line 6, latticed raised line 6 is structure as a whole with sacculus 4, and the material of sacculus 4 is fluorine-containing anti-biotic material.

Under a kind of bronchoscope as shown in Figure 2, expansion air flue foley's tube, be connected with soft 5 of some flexible support between wire leading pipe 1 and inner catheter 2.

Expansion air flue foley's tube under a kind of bronchoscope of the present utility model, when using this air flue foley's tube to keep bronchus unobstructed, in conjunction with bronchoscope, sacculus 4 extends lesion, the outwards interior inflation of airway 3, thereby make sacculus 4 expansions, utilize sacculus 4 extranets trellis raised lines 6 to increase the frictional force between sacculus 4 lesion, now can not produce superslide, just can not misplace with lesion, the antimicrobial form sacculus 4 of fluorine-containing anti-biotic material, has anti-infectious function, in operation process, can reduce the incidence rate of infective inflammation, reduce the painful and uncomfortable of patient, promoted dramatically safety coefficient.

The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to the claim scope.
