Embodiment Construction

[0014] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0015] figure 1 A structural schematic diagram of a urinary catheter for dilating the urethra is shown, which is characterized in that it includes a urinary catheter 1, an expansion device 3 and a positioning device 2, and the positioning device 2 is arranged at the head end of the urinary catheter 1; The expansion device 3 is arranged on the urinary catheter 1; the tube wall of the urinary catheter 1 is provided with a interlayer space, and the interlayer space is provided with an axial partition 11, so that the upper part of the interlayer space forms an upper pipeline with an independent space 12. Make the lower part of the interlayer space form a lower pipe 13 with an independent space. The head end of the urinary catheter 1 is provided with a hemispherical protruding sealing part, and the middle position of th...

Abstract

The invention discloses a catheter for urethra dilation and a production method for the same and belongs to the technical field of medical appliances. The method comprises the steps of (1) preparation of the catheter, (2) preparation of a positioning device and (3) preparation of a dilation device. The invention also discloses the catheter for the urethra dilation. The method provided by the invention is simple, can be implemented easily and is low in cost. The product provided by the invention has clever design and a rational structure. When the catheter is inserted into a urethra, the positioning device and the dilation device are shrunk and can thus be closely adhered to the outer wall of the catheter, so that an outer diameter of the catheter is effectively reduced and a patient's pain can be relieved; by the positioning device, the catheter can be effectively positioned in a bladder, so that the dilation device can easily carry out positioning and dilation actions to parts in need of dilation; during the dilation, intermittent gas inflation or liquid filling is adopted, so that the urethra dilation and a urethral stricture treatment can be implemented; safety and effectiveness of operations are greatly enhanced; and extensive generation and application can be implemented.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a urinary catheter for dilating the urethra and a production method thereof. Background technique [0002] Urethral stricture is a difficult and common disease in urology, and urethral dilatation is an important means of examination and treatment. For this reason, design a kind of treatment equipment that can not only catheterize, but also can treat urethral stricture simultaneously more conveniently treat. At present, the catheters used in hospitals are usually made of latex or silicone tubes. Since the outer diameter of the catheter cannot be changed, if the design is too small, a gap will be formed between the outer wall of the tube and the urethra, resulting in urine leakage; The size is equivalent to the inner wall of the urethra, and it causes pain for the patient during insertion, especially for patients with urethral stricture or obstruction, and it is also dif...
