Description

Technical Field

[0001] This utility model relates to the field of gastrostomy simulation model technology, specifically a percutaneous endoscopic gastrostomy simulation model. Background Technology

[0002] Percutaneous endoscopic gastrostomy (PEG) is a technique that involves percutaneously inserting a gastrostomy tube into the stomach under endoscopic guidance to provide enteral nutrition. PEG has advantages such as minimal invasiveness, low cost, the ability to be administered under local anesthesia, and long-term use, providing a relatively safe and effective minimally invasive surgical approach for establishing long-term enteral nutrition support. Compared with nasogastric tubes, PEG offers better compliance, higher quality of life, and reduces the incidence of reflux and aspiration pneumonia, making it the preferred method for individuals with head and neck malignancies, esophageal cancer, neurological disorders, Crohn's disease, and other conditions requiring long-term home enteral nutrition. Patients with catheters often have short hospital stays after placement and lack effective access to relevant knowledge and skills. After discharge, they rely solely on themselves or their caregivers for home care, which can easily lead to complications such as peristomal skin infection, peristomal leakage, peristomal granulation tissue hyperplasia, embedding syndrome, catheter blockage, and catheter breakage due to improper care. Therefore, it is necessary to provide professional health education to patients and their caregivers so that they can master the skills of daily catheter maintenance and ensure the smooth implementation of enteral nutrition at home.

[0003] Currently, clinical findings indicate several challenges in providing professional health education to PEG patients and their caregivers, as well as ensuring healthcare workers' understanding of PEG-related knowledge and maintenance skills: 1. Traditional health education methods are ineffective. PEG patients and their caregivers need to master certain catheter maintenance skills, including peristomal skin cleaning and disinfection, flushing, catheter insertion and transfer, catheter fixation, and identification and prevention of related complications—all of which are abstract, complex, and difficult to understand. 2. PEG patients and their caregivers experience significant psychological burden during initial catheter maintenance. Due to a lack of medical knowledge and experience in maintaining feeding tubing, caregivers often experience tension, anxiety, and reluctance when guided by healthcare workers during the initial stages of PEG catheter maintenance, making effective health education difficult. 3. PEG-related knowledge and maintenance skills are not yet widespread among healthcare workers at all levels of medical institutions. Currently, PEG maintenance education is not included in higher education nursing curricula. Consequently, some nurses have not fully mastered PEG tubing maintenance knowledge and skills, and this lack of knowledge among some healthcare workers hinders the implementation and promotion of PEG.

[0005] This utility model provides the following technical solution: a percutaneous endoscopic gastrostomy simulation model, including a simulated abdominal wall, a simulated stomach, and a gastrostomy tube; the two ends of the gastrostomy tube are a feeding input end and a feeding output end, respectively.

[0019] Please see Figure 1-5 :

[0020] Example 1: A percutaneous endoscopic gastrostomy simulation model, comprising a simulated abdominal wall 1, a simulated stomach 2, and a gastrostomy tube 3;

[0021] The simulated abdominal wall skin is made of addition-cured liquid silicone, which highly replicates the texture and thickness of abdominal skin and highlights the anatomical positions of the left ribs and umbilicus. Furthermore, the addition-cured liquid silicone abdominal skin allows patients and their caregivers to repeatedly simulate percutaneous skin disinfection; the disinfectant is easily wiped clean, facilitating multiple simulations by multiple people.

[0022] Simulated stomach: It restores the shape, structure and wall thickness of the stomach, realistically reflecting its anatomical structure and location, making it easier to understand the key points of catheter placement and maintenance more intuitively and deeply during training and simulation exercises.

[0023] (1) Location: Restore the position of the human stomach on the body surface.

[0024] (2) Shape: Reproduce the real shape and thickness of the human stomach, select the cross section of the stomach and fix it in the corresponding position on the abdominal wall.

[0025] (3) Structure: ① Reconstruct the anatomical structure of the cardia, lesser curvature, greater curvature, and pylorus of the stomach;

[0026] ②Restore the four layers of gastric wall tissue: serosa, muscularis, submucosa, and mucosa;

[0027] ③Restore the folds of the stomach lining;

[0028] Gastrostomy tube: Two common PEG tube types are available: pad type and balloon type, which can be used interchangeably for training and simulation practice, while replicating the material and components of the PEG tube.

[0029] (1) Gasket type PEG tube

[0030] ①Catheter: made of polyurethane, with a silicone gastric fixation disc, with centimeter markings starting from the gastric fixation disc up to 12cm;

[0031] ② Abdominal wall external fixation pad: made of silicone;

[0032] ③ Feeding connector: made of polyurethane.

[0033] (2) Balloon-type PEG tube

[0034] ① The catheter is made of silicone rubber and has a water-filled silicone rubber balloon (equivalent to an internal fixation disc) at the end. There are centimeter markings starting from the balloon up to 6cm.

[0035] ②Abdominal wall external fixation pad: made of silicone rubber;

[0036] ③ Feeding connector: made of silicone rubber

[0037] The device includes a simulated abdominal wall 1, a simulated stomach 2, and a gastrostomy tube 3. The two ends of the gastrostomy tube 3 are a feeding input end and a feeding output end 11, respectively. The feeding input end is detachably equipped with a feeding infusion port 5, and the feeding output end 11 is provided with an internal fixation plate 4. The feeding output end 11 is fixed to the inner surface of the simulated stomach, i.e., the gastric mucosa, by the internal fixation plate 4 at its end. The gastrostomy tube 3 located outside the simulated abdominal wall is detachably equipped with an external abdominal wall fixation pad 6, which is used to fix the gastrostomy tube 3 to the outside of the simulated abdominal wall 1.

[0038] The simulated abdominal wall 1 has a supporting component on its outer side.

[0039] The outer surface of the gastrostomy tube 3 is provided with a quick-release clip 7 for clamping the gastrostomy tube 3.

[0040] The feeding inlet is equipped with a protective cover, which is integrated with the feeding inlet.

[0041] The supporting components are two adhesive elastic waistbands 8, which are fixedly installed on both sides of the simulated abdominal wall 1.

[0042] Waist belts are attached to both sides of the simulated abdominal wall, allowing the model to be fixed to the abdomen of a patient or mannequin for catheter maintenance practice. The waist belts use self-adhesive Velcro, and the tightness can be adjusted according to waist size.

[0043] The gastrostomy is located on the upper left abdomen, near the navel.

[0044] Example 2: The difference between this example and Example 1 is that the supporting components are a support frame 9 and a connecting block 10. The support frame 9 and the connecting block 10 are movably connected, and the connecting block 10 is fixedly connected to the simulated abdominal wall 1.

[0045] A collapsible model support is installed below the stomach on the back of the simulated abdominal wall 1. When using the model for training, the support can be used to place the model on a table for support, facilitating intuitive demonstration. The support is made of stainless steel, and the thickness of the stainless steel needs to be adjusted according to the size of the model. The support must ensure that the model is stably supported on the table.

[0046] In summary, this percutaneous endoscopic gastrostomy simulation model addresses the shortcomings of traditional health education methods, the significant psychological burden faced by PEG patients and their caregivers during catheter maintenance in the early stages of catheter placement, and the lack of widespread dissemination of PEG-related knowledge and maintenance skills among healthcare professionals at all levels. It can be used for training professionals at all levels of healthcare institutions and for conducting health education for PEG patients and their caregivers. This model overcomes the drawbacks of traditional health education, meets the simulation needs of PEG patients and their caregivers, and aims to improve the effectiveness of health education on catheter maintenance skills for PEG patients and their caregivers, thereby ensuring the smooth long-term home enteral nutrition of PEG patients.
