Abstract
The utility model discloses a urethral catheter with a bent guide head. The urethral catheter comprises the guide head and a drainage tube; the guide head is arranged at one end of the drainage tube; an included angle is arranged between the center line of the guide head and the center line of the drainage tube; and the range of the included angle is between 120 DEG and 170 DEG. According to the urethral catheter with the bent guide head, the guide head and the drainage tube are not located at the same straight line, i.e. the included angle is formed between the guide head and the drainage tube, the urethral catheter is of a bent shape and accords with the urethra and bladder structure of a human body, when the urethral catheter is used, the guide head can be more easily inserted into a bladder through pushing and suitably rotating, and then, the pain for a patient is reduced.
Description
Technical field
This utility model relates to technical field of medical instruments, is meant the catheter that a kind of top guide is crooked especially.
Background technology
Catheter is a kind of common medical device; It generally is the pipe of doing with rubber, silica gel or plastic cement; Can be through per urethram inserting bladder so that drainage of urine comes out, after catheter inserts bladder, near the catheter head end have an air bag fixedly catheter stay intravesical; And be difficult for deviating from, and drainage tube connects urinal collection urine.Catheter commonly used generally comprises top guide, drainage tube and urine collecting bag, and top guide is arranged on an end of drainage tube, directly drainage tube is brought together during making, forms the round end of gradual change.During use, top guide inserts urethra, is inserted under the force urges outside in the bladder, because top guide is designed to the round end shape, can not cause the twinge of urethra.But top guide is general and mozzle is on the same straight line, and promptly top guide is designed to straight peen, and there are crooked situation in human body urethra and bladder structure, and the top guide of straight peen is difficult for importing, and has increased the difficulty of urethral catheterization operation, has also increased patient's when top guide inserts urethra pain.
Summary of the invention
The purpose of this utility model is to provide a kind of catheter of elbow, meets human body urethra and bladder structure, makes top guide insert bladder more easily, reduces patient's pain, and is simple in structure, easy to use.
For realizing the purpose of this utility model, intend adopting following technical scheme:
The catheter that a kind of top guide is crooked, it is characterized in that: comprise top guide and drainage tube, top guide is arranged on an end of drainage tube, is provided with angle between described top guide centrage and the drainage tube centrage, and the scope of its angle is 120 ° to 170 °.
As further specifying, described angle is 145 °.
Compared with prior art, top guide of this utility model and drainage tube are not on the same straight line, and promptly top guide and drainage tube are provided with angle; Be bending; Meet human body urethra and bladder structure, during use, thrust adds suitable rotation; More easily top guide is inserted in the bladder, reduced patient's pain.
Description of drawings
Fig. 1 is the structure chart of this utility model embodiment.
Label among the figure is: 1, top guide; 2, drainage tube; 21, urethral catheterization hole; 22, interface.
The specific embodiment
Further specify the technical scheme of this utility model below in conjunction with accompanying drawing and embodiment.
In conjunction with Fig. 1, the catheter of this utility model embodiment comprises top guide 1 and drainage tube 2, and an end of drainage tube 2 is provided with top guide 1, in the manufacturing process, when bringing drainage tube 2 together, suitably will bring partial rotation together, then forms the top guide 1 of natural torsion.Between the centrage of the centrage of top guide 1 and drainage tube 2, have angle, the scope of its α is 120 °≤α≤170 °.Through repeatedly clinical trial, best angle is 145 °, and this moment, top guide 1 was inserted in the bladder more easily.Position near top guide 1 on drainage tube 2 is provided with urethral catheterization hole 21, and after top guide 1 was inserted into bladder, urine entered into drainage tube 2 through urethral catheterization hole 21.The other end at drainage tube 2 is provided with interface 22, is communicated with the drainage tube of urine collecting bag or urine collecting bag.
Claims (2)
