Visual device special for bladder water sac expansion

Abstract

The invention discloses a visual device special for bladder water sac expansion, and the device comprises a rod body and an external power source; a connecting cylinder is arranged in the rod body, an arc-shaped end is arranged at the end of the rod body, a bag outlet is formed in the arc-shaped end, the bag outlet is communicated with the interior of the rod body, a sliding rod is arranged in the connecting cylinder in a sliding mode, the end of the sliding rod is fixedly sleeved with a bag, an observation mirror is installed on the outer wall of the end of the connecting cylinder, an electromagnet arranged in an arc shape is fixedly embedded in the end of the connecting cylinder, and the electromagnet is connected with an external power source through a wire. An electromagnet block arranged at the end of the sliding rod and a magnet plate in the bag are attracted in the moving process, the bag can be conveniently pulled into a bag outlet for storage, urethral injury caused by contact between the bag and the urethra in the outward moving process of the rod body is avoided, a certain expansion degree of the bag is guaranteed by arranging a trigger mechanism, and the bladder injury caused by overlarge expansion degree is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a special device for visual bladder water bladder expansion. Background technique [0002] Cystitis is an inflammation of the bladder, mainly caused by specific and non-specific bacterial infections, and there are other special types of cystitis, the common one is interstitial cystitis, which is a special chronic cystitis. The main symptoms are severe frequent urination, urgency, lower abdominal pain, dysuria, hematuria and so on. More common in female patients. Generally, a decrease in bladder capacity and submucosal hemorrhage in the bladder wall are found during cystoscopy. Immediately after the diagnosis of interstitial cystitis is confirmed, therapeutic water expansion is performed to reduce pain, increase bladder capacity, and prolong the storage period of the bladder. Increases urine output and bladder capacity. [0003] Authorized notification number CN20352512...

AI Technical Summary

Problems solved by technology

[0003] Authorized notification number CN203525125U discloses a special device for visual bladder water bag expansion, which includes a tube sheath with a movable tube core inside, and a transparent cylindrical expansion air bag is sealed at the outlet end of the tube sheath; the cylindrical expansion air bag The opening end is sealed and connected with the outlet end of the sheath; the length of the movable tube core is greater than the sum of the lengths of the sheath and the cylindrical expansion balloon; a hole is opened on the wall of the sheath near the inlet end, and an inlet is connected to the hole. There is a water control valve on the water inlet pipe; there is a hole on the outer wall of the sheath near the inlet end, and the hole is connected with a pressure gauge by a pressure measuring tube; it can be better adhered to by the support of the movable tube core. Attached to the surface of the tube core, so that the outer surface of the expansion bag is smooth and wrinkle-free, and the damage to the urethral mucosa is small when entering and leaving the urethra, but in the actual use process, the water bag will still appear during the shrinkage of the vacuum bag The surface is wrinkled due to rapid contraction or shrinkage deformation after stretching, so it will still cause damage to the urethra
