Problems solved by technology

Postoperative wounds will not only cause symptoms such as bleeding, exudation, pain, itching, and burning, which will bring pain to patients; but also prone to problems such as wound granulation tissue hyperplasia, wound pseudo-healing, uneven healing surface, and scar hyperplasia
Conventional sitting pressure therapy such as cotton pad compression is generally used to solve the problems of overgrowth of granulation, hyperplasia of scars, uneven wound surface and other problems after surgery, but the effect is not ideal, resulting in many patients still need to undergo surgery again after recovery from surgery To solve the local overly prominent granulation or scar hyperplasia tissue

Embodiment 1

[0073] An anorectal postoperative recovery aid material, such as figure 1 As shown, the material is a cylinder with a round head at one end, and the material includes an inner core 1, a water-absorbing swelling layer 2 and a drug layer 3 from the inside to the outside, and the drug layer 3 is prepared from mupirocin ointment; the inner core The round end of the inner core 1 is connected to the water-absorbing swelling layer 2, and the unconnected part between the inner core 1 and the water-absorbing swelling layer 2 is also provided with a lubricating layer 9.

[0074] In this embodiment, the water-absorbing swelling layer 2 can be made of flexible polymer water-absorbing material. The polymer water-absorbing material with a water-absorbing swelling rate of 100-200% is preferred, and the effect is better when the thickness of the water-absorbing swelling layer 2 is designed to be 2-4mm.

Embodiment 2

[0076] A kind of anorectal disease postoperative recovery auxiliary material, different from embodiment 1, such as figure 2 As shown, the material also includes a bottom sticker 4, the bottom sticker 4 is connected to the non-round end of the inner core 1, and the upper surface of the bottom sticker 4 is sequentially provided with a lubricating layer 9, a water-absorbing swelling layer 2 and a drug layer 3; the material A through hole 5 along the central axis of the cylinder is arranged on the top, and the lower end of the through hole 5 penetrates the bottom sticker 4 .

[0077] In this embodiment, the bottom sticker 4 and the inner core 1 may be of an integral structure; or the bottom sticker 4 and the bottom end of the inner core 1 may be fixedly connected with an adhesive or the like.

Embodiment 3

[0079] A kind of anorectal disease postoperative recovery auxiliary material, different from embodiment 2, such as image 3 As shown, the side of the drug layer 3 away from the water-absorbing swelling layer 2 is also provided with a drug-permeable membrane 6, the drug-permeable membrane 6 is an elastic anti-adhesive film provided with several drug-permeable holes, and the lower surface of the bottom sticker 4 is sequentially provided with a self-adhesive layer 7 and release paper 8.

Abstract

The invention belongs to the field of medical materials, and in particular relates to an auxiliary material for postoperative recovery of anorectal diseases. The material is a cylinder with a round head at one end. The material includes an inner core, a water-absorbing swelling layer and a drug layer in sequence from the inside to the outside. One end of the round head of the inner core is connected to the water-absorbing swellable layer, and a lubricating layer is provided on the unconnected part between the inner core and the water-absorbent swellable layer. The postoperative recovery auxiliary material for anorectal disease provided by the present invention is used for the postoperative recovery treatment of patients with anorectal disease. After the recovery period, it can reduce the postoperative pain of patients; and it can also effectively avoid the problems of excessive growth of granulation and scar hyperplasia on the wound surface, so that the wound surface can remain smooth after recovery.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to an auxiliary material for postoperative recovery of anorectal diseases. Background technique [0002] Anorectal disease is a clinical frequently-occurring disease. According to relevant statistics, the incidence rate of hepatic portorectal disease exceeds 50%. The treatment method of anorectal disease mainly comprises medicine oral administration at present, medicine external application and surgical treatment. Among them, the curative effect of the medicine taken orally is slow, and it is easy to be polluted or damaged again during the recovery process, resulting in other diseases; the medicine used externally cannot fully play its role, the curative effect is minimal, and the frequency of dressing changes is relatively frequent, and the patient's compliance is low. And these two methods can only treat patients with milder conditions, and are difficult to have obvio...
