Abstract

The utility model relates to an aerocyst urethral catheter, which comprises a urethral catheter wall. A liquid drainage cavity is arranged on the inner side of the urethral catheter wall, an aerocyst inflating cavity and a liquid replenishing cavity are further disposed on a wall section of the outer side of the liquid drainage cavity, and the liquid drainage cavity on an axial section of the urethral catheter is oval. The aerocyst urethral catheter is simple in structure, effectively utilizes limited space of the section of the urethral catheter without increasing the diameter of the catheter, greatly increases liquid drainage sectional area of a urethra, and leads urination to be smoother.

Description

A kind of Foley catheter

Technical field

This utility model relates to a kind of medical treatment device, relates in particular to a kind of Foley catheter.

Background technology

Foley catheter claims sacculus urinary catheter or Foley ' s pipe again, and the branch in two-chamber and three chambeies is arranged, and as the succedaneum of ordinary urethral catheter, has been widely used in clinical at present.It has simple to operate, and the tube wall softness is little to mucosa irritation, and internal fixation is stable, need not immobilization with adhesive tape, inserts the back in advantages such as the urinary catheter closed intensity are big.But conditions of patients changes suddenly, during situations such as appearance hematuria, the narrow situation of efferent tract then can appear in urinary catheter, the cross section of catheter is circle at present, urinary catheter is provided with the pipeline of two or three circular cross-sections, do not effectively utilize limited space, exist and arrange irrationality greatly.

The utility model content

The purpose of this utility model is to address the above problem and provide a kind of simple in structure, and is easy to operate, can maximum using pipeline section space, and rationally distributed Foley catheter.

This utility model solves the problems of the technologies described above the technical scheme that is adopted:

It comprises the urethral catheterization tube wall, and urethral catheterization tube wall inboard is an exhaust chamber, also is provided with air bag on the tube wall cross section in the exhaust chamber outside and fills up chamber and fluid infusion chamber, and described exhaust chamber is at the ellipse that is shaped as of catheter axial cross section.

Compared with prior art, this utility model has been obtained following technique effect:

1, this utility model is simple in structure, is not increasing on the pipe diameter basis, and it has effectively utilized the limited space of urethral catheterization pipeline section, has increased the discharge opeing sectional area of urethra greatly, make urinate more smooth and easy.

Description of drawings

Fig. 1 is a double lumen catheter schematic cross-section in the prior art;

Fig. 2 is a three-cavity catheter schematic cross-section in the prior art;

Fig. 3 is this utility model schematic cross-section.

Wherein: the 1-air bag fills up chamber, 2-exhaust chamber, 3-urethral catheterization tube wall, 4-fluid infusion chamber.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Embodiment 1

Referring to Fig. 1, a kind of Foley catheter, it comprises urethral catheterization tube wall 3, and urethral catheterization tube wall inboard is an exhaust chamber 2, also is provided with air bag on the tube wall cross section in the exhaust chamber outside and fills up chamber 1 and fluid infusion chamber 4, and described exhaust chamber is at the ellipse that is shaped as of catheter axial cross section.

Referring to Fig. 1-3, this catheter is compared with traditional two-chamber or three-cavity catheter, and wherein urethral catheterization lumen is that exhaust chamber changes ellipse into, under identical caliber, increase the cross-sectional area of urethral catheterization lumen greatly, greatly improved the smoothness when using, avoided the narrow defective of conventional cross-section pipeline.

Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model this utility model.If these changes and distortion belong in the scope of this utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.

Claims

1. Foley catheter, it comprises urethral catheterization tube wall (3), urethral catheterization tube wall inboard is exhaust chamber (2), also is provided with air bag on the tube wall cross section in the exhaust chamber outside and fills up chamber (1) and fluid infusion chamber (4), and it is characterized in that: described exhaust chamber is at the ellipse that is shaped as of catheter axial cross section.
