Problems solved by technology

Existing urethral dilators are mainly metal urethral dilators and filamentary dilators, both of which need to use metal rods to penetrate into the deep urethra. The patient is more painful when dilating, and sometimes it may cause infection, urethral injury, and false tract. Formation, leading to recurrence of urethral stricture and even perforation of the rectum

Embodiment Construction

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0022] As shown in the figure, the non-invasive air positive pressure urethral dilator of the present invention includes a hollow urethral orifice blocking tube 1 for inflating the urethra and a fastening device, and the fastening device is used to move along the axis of the urethral orifice blocking tube 1. Fasten the urethral orifice blocking tube 1 to the urethral orifice; insert one end of the urethral orifice blocking tube 1 into the urethra, connect the other end to the digital automatic control inflatable device, and connect the fastening device at the same time, and urethral orifice blocking tube 1 It is fastened to the urethral orifice to prevent the urethral orifice from being blocked. The tube 1 is ejected by the air pressure, and the urethra can be inflated to expand.

[0023] In this embodiment, the end of the urethral orifi...

Abstract

The invention discloses a non-invasive air positive pressure urethral dilator, which comprises a hollow urethral orifice blockage tube used for inflating the urethra, and a fastening device used for fastening the urethral orifice blockage tube to the urethral orifice along the axial direction of the urethral orifice blockage tube. The urethral orifice blockage tube can be connected with a digital automatic control inflating device, and the urethra is dilated through inflation, so the non-invasive air positive pressure urethral dilator has the advantages of safety without wounds, no complication, and relief of the pain of the patient; besides, the non-invasive air positive pressure urethral dilator is simple and convenient to operate, and common patients can independently dilate the urethra at home under the guidance of doctors, so the convenience is brought and the burden of visiting the doctor for multiple times is reduced simultaneously.

Description

technical field [0001] The invention relates to a urethral dilator, in particular to a non-invasive air positive pressure urethral dilator. Background technique [0002] Scars formed in the urethra due to trauma, inflammation, surgery and other reasons can lead to urethral strictures, and urethral dilation after urethral incision is a common method for the treatment of urethral strictures. , to dilate the stenosis. Existing urethral dilators are mainly metal urethral dilators and filamentary dilators, both of which need to use metal rods to penetrate into the deep urethra. The patient is more painful when dilating, and sometimes it may cause infection, urethral injury, and false tract. Formation, leading to recurrence of urethral stricture, and even perforation of the rectum. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a non-invasive positive air pressure urethral dilator to reduce the complications caused by dil...
