Description

Technical Field

[0001] The invention belongs to the technical field of anus clinical dressing changing equipment, and specifically refers to a clinical dressing changing device for medical nursing. Background Art

[0002] Hemorrhoids are the most common anorectal disease. Due to the congestion or congestion and swelling of the venous plexus at the lower end of the anal canal or rectum, symptoms such as bleeding and pain during defecation, anal itching, and prolapse of hemorrhoids (commonly known as "flesh warts") are prone to occur. Hemorrhoids can be divided into external hemorrhoids, internal hemorrhoids, and mixed moles. After hemorrhoid removal, the wound cannot be sutured. The wound needs to be left open and allowed to heal slowly. This is mainly because feces are discharged from the anus every day, and the feces contain various bacteria, so it is difficult to thoroughly disinfect the wound. If the bacteria are sutured in the wound, it is easy to cause incision infection. However, the secretions from the wound will cause anal adhesion. Every time the medicine is applied, the anus shrinks, and the wound is difficult to expose. At the same time, feces will adhere to the dressing equipment when changing the dressing. Summary of the invention

[0029] The straight plate clamp 8 and the arc plate 9 are made of rubber material.

[0030] When in use, the disposable antibacterial sleeve 1 needs to be sleeved on the spray angle adjustment device 4 first, the straight plate clamp 8 is passed through the expanded straight plate 17 and clamped, and the curved plate 9 is close to the expanded curved plate 18. In order to be able to insert the support plate sleeve assembly 6 with a narrow upper and wide lower structure on the expanded straight plate 17, the curved plate 9 can be deformed appropriately, and then the spray pipe sleeve 13 is vertically inserted along the embedded clamping strip 40 on the surface of the spray pipe 35, so that the straight plate clamp 8, the curved plate 9 and the spray pipe sleeve 13 are fixed relative to the rocker expander 3; then the perfusion ball 43 is screwed and installed on the bottom wall of the shell 42, and the ball 46 is squeezed by the contact pressure bracket 39 during installation, thereby Open the liquid outlet 45 of the perfusion ball 43; after the equipment is assembled, let the patient lie prone, and insert the front end of the equipment from the site of hemorrhoid onset of the patient. In order to avoid adhesion of the wound, it is necessary to use a pulling method to tear the adhesion site open again. To this end, in order to avoid the collision of the handle 29 with the shell 42, it is necessary to adjust the sliding distance of the handle 29 in the handle vertical slot 30, pinch the handle 29, turn the rotating rocker 26, so that the rotating rocker 26 drives the small gear 22 to rotate, and the small gear 22 is engaged with the gear plate 23, thereby driving the gear plate 23 to rotate.
