Abstract
Description
Technical Field
[0001] This invention relates to the field of peritoneal dialysis technology, and more specifically, to a wearable peritoneal dialysis training model. Background Technology
[0002] Peritoneal dialysis is one of the alternative treatments for end-stage renal disease, with patients primarily receiving home-based care. After peritoneal dialysis catheter placement, the management of the catheter and the procedure for changing the dialysis fluid require education and training from nurses to ensure that patients and their families understand the relevant knowledge to facilitate home-based treatment for peritoneal dialysis patients.
[0003] Currently, patient training begins post-operatively with fluid change training. Patients first watch instructional videos on the procedure to understand the process, followed by a detailed explanation of the requirements, steps, and precautions by a peritoneal dialysis nurse, who then demonstrates the procedure. However, after training, patients often perform these procedures directly on their own peritoneal dialysis catheters, which can easily lead to contamination at the external catheter connector. Furthermore, during hospitalization, nurses handle procedures such as changing dressings at the catheter exit point, securing the catheter, and protecting it during showers. Patients and their families learn solely through nurses' explanations without practical experience, leading to various problems and complications at home, severely impacting the effectiveness and quality of peritoneal dialysis. Clinical training for patients' families can only be provided after peritoneal dialysis catheter placement. However, with the current DRG (Diagnosis Related Groups) healthcare system allowing for greater control over hospital stays, the medical team hopes that patients and their families will quickly acquire the knowledge and skills required for home peritoneal dialysis.
[0004] In view of this, the present invention proposes a wearable peritoneal dialysis training model. Summary of the Invention
[0005] The purpose of this invention is to provide a wearable peritoneal dialysis training model that can better guide peritoneal dialysis patients in performing standardized fluid exchange, dressing changes, and catheter care, thereby reducing the incidence of contamination. In addition, training can be conducted in advance before surgery, thereby shortening the patient's hospital stay, saving medical expenses, and improving the satisfaction of medical staff and patients.
[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a wearable peritoneal dialysis training model, including a peritoneal bag and a peritoneal dialysis catheter, wherein the peritoneal bag is hollow inside, the peritoneal bag is detachably connected to an abdominal model, and the peritoneal dialysis catheter passes through one side of the abdominal model to the other side of the abdominal model and enters the peritoneal bag.
[0007] The present invention is further configured such that: a connecting nozzle is fixedly connected to one end of the abdominal cavity bag near the abdominal model, the connecting nozzle is threadedly connected to a connecting port, and the connecting port is fixedly connected to the abdominal model.
[0008] The present invention is further configured such that: the peritoneal dialysis catheter passes through one side of the abdominal model to the other side of the abdominal model, and enters the abdominal cavity bag through the connecting port and the connecting nozzle.
[0009] The present invention is further configured such that: a waist belt is fixedly connected to both sides of the abdominal model.
[0010] The invention is further configured such that a buckle is provided at the end of the waist belt away from the abdominal model.
[0011] The invention is further configured such that a magic sticker is provided at the end of the belt away from the abdominal model.
[0012] In summary, the present invention has the following beneficial effects:
[0013] 1. The model is strapped to the patient's abdomen and can realistically simulate the patient's peritoneal dialysis catheter placement, outlet position, external short tube connection method, peritoneal dialysis infusion, drainage process, etc., allowing the patient to have an intuitive understanding of their postoperative condition and the peritoneal dialysis treatment process.
[0014] 2. It makes it easier for nurses to demonstrate the procedures for changing IV fluids and dressings to patients.
[0015] 3. Patients can practice before or after surgery, which shortens the education and training time and the length of hospital stay.
[0016] 4. Patients and their families can also use the model to repeatedly practice the procedures for changing fluids and medications, improving training effectiveness, reducing peritoneal dialysis complications, and thus improving the quality of peritoneal dialysis. Attached Figure Description

[0021] Example:
[0022] A wearable peritoneal dialysis training model, such as Figure 1 , Figure 2 As shown, it includes an abdominal pouch 3 and a peritoneal dialysis catheter 4. The abdominal pouch 3 is hollow inside. The abdominal pouch 3 is detachably connected to an abdominal model 1. The peritoneal dialysis catheter 4 passes through one side of the abdominal model 1 to the other side of the abdominal model 1 and enters the interior of the abdominal pouch 3.
[0023] Among them, the abdominal model 1: realistically simulates the shape of the human abdomen, with the peritoneal dialysis catheter 4 passing through below the navel, simulating the actual position of the peritoneal dialysis catheter 4;
[0024] Abdominal cavity bag 3: It can hold 5L of liquid and is made of transparent plastic to realistically simulate the human abdominal cavity;
[0025] Peritoneal dialysis catheter 4: This is the peritoneal dialysis catheter 4 used in actual clinical practice. The end of the catheter is not at the bottom of the abdominal bag 3, which can realistically simulate the process of fluid inlet and outlet.
[0026] In this embodiment, a connecting nozzle 6 is fixedly connected to one end of the abdominal pouch 3 near the abdominal model 1. The connecting nozzle 6 is threadedly connected to a connecting port 5, which is fixedly connected to the abdominal model 1. The peritoneal dialysis catheter 4 passes through one side of the abdominal model 1 to the other side, and enters the interior of the abdominal pouch 3 through the connecting port 5 and the connecting nozzle 6.
