Abstract

The utility model discloses a compound catheter, which comprises an outer catheter 1, an inner catheter 2 and/or a liquid reservoir 3. The utility model is characterized in that the outer catheter 1 is a flexible hollow pipe whose front end is provided with a front end head 7 which is solid and a liquid guiding hole 4 is arranged on the portion a little closer to the back end. The inner catheter 2 is a rigid hollow pipe whose front end is provided with an inner catheter arc 6 and the back end is the section 5 which is provided with a plurality of small holes of an inner guiding hole. The tail portion of the inner catheter 2 is provided with an alary handle 9. The utility model has the advantage that the inner catheter and the outer catheter are matched for use. Not only the defect that a rubber flexible pipe is uneasy to be inserted is solved but also the shortages that a metal catheter forms a false passage and has uneasy reservation are overcome.

Description

A kind of combined type catheter

This utility model relates to medical apparatus and instruments, particularly catheter.

The catheter of prior art roughly is divided into two kinds, and one is flexible, as the catheter of rubber hose formula; Another kind is inflexible, for example metal catheter.Rubber catheter is too soft, is difficult to insert; And metal catheter form easily via and be difficult for keeping.Because the deficiency that two kinds of above catheters exist has proposed the purpose of this utility model.

The purpose of this utility model is a kind of combined type catheter of design.

The purpose of this utility model is to realize according to following structure.Comprise an outer catheter, an inner catheter and/or a liquid reservoir.Outer catheter is the hollow pipe of a flexibility, and its front end has one section solid front end, and a delivery hole is arranged after slightly leaning on.Inner catheter is an inflexible hollow pipe, and front end has one section inner catheter arc, is thereafter an interior guide hole section with a plurality of apertures, at the afterbody of inner catheter, a wing handle is arranged.The bell-mouthed segment of likeness in form that has a port slightly to enlarge at the end of outer catheter links with the tube head of liquid reservoir front end.Outage, steam vent and hanging hole are arranged on liquid reservoir, use to be fit to various patient, convenient and practical.

Outer catheter is used in the utility model has the advantages that, has both solved the rubber flexible catheter and has been difficult for the shortcoming inserted, overcome again metal catheter form via with the deficiency that is difficult for keeping.

The following drawings explanation, Fig. 1 is the sketch map of outer catheter, and Fig. 2 is the sketch map of inner catheter, and Fig. 3 is the sketch map of liquid reservoir, and Fig. 4 is that A among Fig. 2 is to view.Each sequence number in the accompanying drawings is: 1 outer catheter, 2 inner catheters, 3 liquid reservoirs, 4 delivery holes, 5 interior guide holes, 6 inner catheter arcs, 7 front ends, 8 hanging holes, 9 handles, 10 outages, 11 steam vents.

Describe in detail below in conjunction with the embodiment in the accompanying drawing, with reference to accompanying drawing, outer catheter 1 is the hollow pipe of a flexibility, and front end 7 is one solid section, is thereafter a delivery hole 4, and end is a slightly horn opening of expansion.Inner catheter 2 is one and has inflexible hollow pipe, its front end has a curved inner catheter arc 6, guide hole 5 in one section is arranged in the arc crook, this section cooperates with delivery hole 4 on the outer catheter, its end has the handle 9 of a flat, and liquid reservoir 3 front ends have one section conduit, can use with the tip engages of outer catheter, the end of the liquid-collection bag of liquid reservoir 3 has an outage 10, and a steam vent 11 and a hanging hole 8 are arranged at the top of its bag.Outer catheter can use rubber or plastic material to make, and inner catheter can use rustless steel, marmem or hard plastics to make, and liquid reservoir can use materials such as softer plastics such as polyethylene to make.Inner catheter is generally slightly long than outer catheter, during use, inner catheter is inserted in the inside of outer catheter and uses, when intubate puts in place, the urine of retention is after the end outflow of inner catheter, inner catheter can be extracted out in outer catheter, and, can normally be used the catheter proximal end of liquid reservoir and the terminal firm plug of outer catheter.

Claims

1, a kind of combined type catheter, comprise outer catheter 1, inner catheter 2 and/or liquid reservoir 3, it is characterized in that outer catheter 1 is the hollow pipe of a flexibility, its front end has one section solid front end 7, and it is that its front end of inflexible hollow pipe has one section inner catheter arc 6 that a delivery hole 4, inner catheter 2 are arranged after slightly leaning on, be an interior guide hole section 5, a wing handle 9 arranged at the afterbody of inner catheter 2 with a plurality of apertures thereafter.
