A cesarean section incision waterproof wound care bathing briefs

Abstract

This invention provides a waterproof and protective bath panty for cesarean section incisions. Compared with existing technologies, this invention's waterproof and protective bath panty for cesarean section incisions is composed of an inner waterproof layer, a middle breathable insulating layer, and an outer skin-friendly adhesive layer, forming a tubular panty body. The waistband and leg openings are folded back to form an annular edge channel, with an elastic sealing ring inside the channel. The inner side of the channel has an inward-folding waterproof lip to form a circumferential seal. The edge channel has an inlet for assembling and sealing the sealing ring. The left and right sides of the panty body have tear-away edges, and a pull tab near the waistband allows for tearing from top to bottom. The sealing ring has a pre-fractured section aligned with the tear-away edge, so the sealing ring breaks simultaneously when torn. This structure effectively prevents shower water from entering the incision area, while maintaining breathability and comfort, supporting quick and easy removal, and reducing traction pain and the risk of infection.

Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to a waterproof protective bath underwear for cesarean section incisions. Background Technology

[0002] After a cesarean section, mothers often require a relatively long recovery period for their incision. During this time, they still need daily cleaning and bathing, but the cesarean section incision is located in the lower abdomen and is easily affected by shower water. If water repeatedly gets into the incision, it can easily lead to local dampness and seepage, causing discomfort to the mother and potentially delaying wound healing and increasing the risk of infection. Therefore, effectively preventing water from getting into the incision during bathing while ensuring breathability and comfort has become a practical need in the care of mothers who have undergone cesarean sections.

[0003] Currently, there are two main types of protective methods: one is to use disposable waterproof films to directly cover the cesarean section incision site to block moisture; the other is to use waterproof underwear or protective pants with elastic bands, zippers, or Velcro at the waist and leg openings to achieve waterproofing through tightness or localized sealing. These methods can reduce water ingress into the incision to some extent, but they generally have limitations such as discontinuous sealing, inconvenience in putting on and taking off, and poor breathability. Especially when the mother's body shape fluctuates or bending over is restricted, the effectiveness and comfort of use are often affected.

[0004] In order to solve the common problems in this field, such as the protective film being prone to peeling or falling off, the protective pants relying on dotted or linear seals which pose a risk of leakage, and the need to put them on and take them off from the feet, which increases the burden on the mother when bending over or lifting her legs, and can easily pull on the wound and cause pain, this utility model was made. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the current field by proposing a waterproof and protective bathing underwear for cesarean section incisions.

[0006] In order to overcome the shortcomings of the existing technology, the present invention adopts the following technical solution:

[0007] A waterproof and protective bath panty for cesarean section incisions, comprising a pant body, openings in the pant body, and sealing structures at each opening in the pant body.

[0008] The opening includes a waist opening and two leg openings;

[0009] The sealing structure includes three annular edge-sealing channels that are respectively formed around the waist opening and the two leg openings, and a telescopic sealing ring that is accommodated in each annular edge-sealing channel and fits in circumferentially with the human body.

[0010] The annular edge-sealing channel has an inwardly turned water-stopping lip on the side facing the human body, so that the telescopic sealing ring and the water-stopping lip cooperate to form a tight seal at the waist and leg openings.

[0011] Furthermore, the left and right sides of the pants body are respectively provided with tearable and removable edges. The tearable and removable edges include a row of through micro-holes with a micro-hole diameter of 0.3-0.8mm and a hole spacing of 1-3mm, and a pull tab that is pasted to the through micro-holes near the waist. The pull tab serves as the tearing part. When in use, the pull tab is grasped and torn from top to bottom along the tearable and removable edge to detach the side edge of the pants body.

[0012] Furthermore, the pants body has a three-layer functional composite structure, which includes a waterproof layer, a breathable insulating layer, and a skin-friendly adhesive layer from the inside out. The waterproof layer, the breathable insulating layer, and the skin-friendly adhesive layer are connected together as one unit by heat sealing, ultrasonic welding, or hot melt adhesive mesh.

[0013] The beneficial effects achieved by this utility model are:

[0014] 1. The annular edge-sealing channels at the waist and leg openings, combined with the water-stopping lip and the telescopic sealing ring, form a continuous circumferential seal, effectively preventing shower water from entering the cesarean section incision area and significantly reducing the risk of incision maceration and infection.

[0015] 2. The pants feature a three-layer functional composite structure: an inner waterproof layer, a middle breathable and insulating layer, and an outer skin-friendly and close-fitting layer. This ensures both excellent waterproof performance and breathability and skin-friendly comfort, enhancing the postpartum experience.

[0016] 3. Tearable and removable edges are provided on both sides of the pants, and pre-fractured sections are arranged on the annular binding channel and the telescopic sealing ring. With the waist pull tab, it can be quickly removed without feet after bathing, reducing the bending and leg lifting movements of postpartum women, reducing incision traction pain, and facilitating single use and disposal, thus improving hygiene and convenience.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be noted that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this invention. Other systems, methods, and / or features of this embodiment will become apparent to those skilled in the art after reviewing the following detailed description. Furthermore, the terminology used to describe positional relationships in the accompanying drawings is for illustrative purposes only and should not be construed as limiting the scope of this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0022] Example 1: Combined with Appendix Figure 1 and attached Figure 2 This embodiment constructs a waterproof and protective bathing panty for cesarean section incisions. The panty includes a panty body, openings in the panty body, and sealing structures at each opening.

[0023] The opening includes a waist opening and two leg openings;

[0024] The sealing structure includes three annular edge-sealing channels that are respectively formed around the waist opening and the two leg openings, and a telescopic sealing ring that is accommodated in each annular edge-sealing channel and fits in circumferentially with the human body.

[0025] The annular edge-sealing channel has an inwardly turned water-stopping lip on the side facing the human body, so that the telescopic sealing ring and the water-stopping lip cooperate to form a tight seal at the waist and leg openings.

[0026] The annular edge banding channel is formed by folding the edge of the trouser body inward in a circumferential direction. The overlapping section of the folded part of the trouser body and the trouser body body is continuously sealed by heat sealing / hot pressing / ultrasonic welding to form a circumferentially closed channel with an effective width of 8–20 mm. A narrow non-woven tape is laid at the edge banding on the side facing the human body and welded synchronously with the edge banding, so that the non-woven tape forms an inwardly turned water-stopping lip.

[0027] An inlet with the same width as the channel is reserved on the annular edge-sealing channel. The telescopic sealing ring is pre-cut to a predetermined length by a continuous long elastic strip / elastic rope. Then, the continuous long elastic strip is fed in from one side of the inlet and pulled around the annular edge-sealing channel, so that both ends of the elastic strip are pulled out from the inlet at the same time. Then, the two ends of the elastic strip are aligned at the inlet according to the predetermined overlap length, and the two ends are fused into a closed loop by hot melt welding, ultrasonic welding or resistance hot welding to form a telescopic sealing ring.

[0028] The trousers are provided with tearable edges on both the left and right sides. The tearable edges include a row of through microholes with a diameter of 0.3–0.8 mm and a spacing of 1–3 mm, and a pull tab attached to the through microholes near the waist. The pull tab serves as the starting point for tearing. When in use, the pull tab is grasped and torn from top to bottom along the tearable edges to detach the edge of the trousers on that side.

[0029] The through-hole array with tearable and detachable edges is preferably formed by laser drilling. Under the guidance of a fixture, the through-hole array is formed by pulse ablation point by point along the side generatrix. Alternatively, the through-hole array can be obtained by continuous punching with a micro-punching roller (needle roller) under the constraint of a pressure roller and a side guide rail. The bonding pull sheet is fixed to the through-hole array by hot pressing.

[0030] Furthermore, a pre-fracture section is provided on both the annular edge-sealing channel and the telescopic sealing ring at a position aligned with the tearable edge. The pre-fracture section is formed by any of the following methods: locally thinning / necking the telescopic sealing ring at the aligned position, reducing its thickness by 30% to 50% and its length by 8 to 15 mm; or applying a laser shallow groove / roller scratch / micro-hole array (hole diameter 0.2 to 0.5 mm, hole spacing 1 to 2 mm) to the telescopic sealing ring at this position, but not penetrating the annular edge-sealing channel; at the same time, locally thinning or narrow sealing is used at the corresponding position of the annular edge-sealing channel (such as reducing the width of the sealing weld or reducing the welding energy to form a weakening zone), or only pressing a shallow groove / discontinuous indentation on the inward-turned water-stopping lip, so that when the tearing force is transmitted through the sealing layer of the annular edge-sealing channel, it preferentially acts on the aforementioned weakening zone, thereby causing the telescopic sealing ring to break first at the pre-fracture section and open synchronously with the opening at the annular edge-sealing channel.

[0031] The pants have a three-layer functional composite structure, which includes a waterproof layer, a breathable insulating layer, and a skin-friendly adhesive layer from the inside out. The waterproof layer, the breathable insulating layer, and the skin-friendly adhesive layer are connected together by heat sealing, ultrasonic welding, or hot melt adhesive mesh. The annular binding channels at the waist and leg openings are formed into a seamless seal by continuous hot pressing or ultrasonic welding.

[0032] The inner waterproof membrane is a TPU film or a medical-grade PE / PEVA waterproof membrane, the middle breathable isolation layer is a microporous breathable membrane or a non-woven fabric coated with a breathable coating, and the outer skin-friendly soft layer is one or a combination of cotton / spandex or nylon / spandex knitted fabric.

[0033] Wear these waterproof cesarean section incision dressing underwear directly over regular underwear, ensuring the waistband and leg openings fit snugly against the corresponding areas of the body. A circumferential seal is established through the elastic sealing ring within the elastic ring and the inward-folding waterproof lip on the inner side of the ring. After showering, grasp the pull tab near the waistband and tear it continuously from top to bottom along the tear-off edge. The tearing force is transferred through the sealing layer of the elastic ring to the pre-break section of the elastic sealing ring at the point aligned with the tear-off edge. The elastic sealing ring breaks first at the pre-break section, opening simultaneously with the opening at the elastic ring, allowing the sides of the underwear to quickly detach. Then, unfold the underwear from one side of the body and remove it; there is no need to remove it from the feet. Dispose of as a disposable hygiene product after use.

[0034] This utility model offers a solution to the pain points of postpartum women undergoing cesarean section bathing scenarios, such as easy water ingress into the incision, delayed healing due to maceration, pain from traction during dressing and doffing, unstable sealing, and inconvenience in hygiene. It utilizes a ring-shaped edge channel at the waist and leg openings, combined with an inward-folding waterproof lip and a telescopic sealing ring, to form a continuous circumferential seal, significantly reducing the risk of shower water entering the incision area. A three-layer functional composite (waterproof inner layer, breathable and insulating middle layer, and skin-friendly outer layer) not only blocks water but also allows for moisture wicking and ventilation, reducing the risk of dampness and infection at the incision. The tear-off edges and waist opening pull tab allow for quick, footless removal from top to bottom after washing, reducing the pain and traction on the wound from bending over and lifting the legs. The disposable structure facilitates replacement, reduces cleaning burden and the risk of cross-contamination, while the elasticity of the telescopic sealing ring adapts to changes in postpartum abdominal circumference, improving overall comfort and safety.
