Technical Field
[0001] The utility model relates to the technical field of automatic peritoneal dialysis, in particular to an anti-clamping protection device for a consumable loading port of an automatic peritoneal dialysis machine. Background Art
[0002] Peritoneal dialysis is one of the important means of treating end-stage renal disease. Its principle is to infuse peritoneal dialysis fluid into the abdominal cavity, using the human peritoneum as a semipermeable membrane to remove excess water, metabolites and toxins from the body, thereby purifying the blood and replacing the kidney's detoxification function. Peritoneal dialysis is divided into artificial peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD). Automated peritoneal dialysis uses an automated peritoneal dialysis machine to automatically infuse and remove peritoneal dialysis fluid from the patient's abdominal cavity to complete the peritoneal dialysis operation. Patients who use automated peritoneal dialysis only need to receive treatment at night and can live a normal life during the day. It is an advanced treatment method that is beneficial to improving the patient's quality of life and allowing the patient to return to their family and society.
[0003] The automatic peritoneal dialysis machine needs to be used with disposable consumables during use, so the automatic peritoneal dialysis machine is usually equipped with a consumable loading port, which is usually open after the consumables are installed. During the use of the equipment, if a limb (such as a finger) is inserted into the automatic peritoneal dialysis machine through the consumable loading port, it may cause a certain degree of harm to the patient. Therefore, during the operation of the automatic peritoneal dialysis machine, the consumable loading port needs to be automatically closed or blocked to prevent the patient's fingers or other limbs from being pinched to ensure the safety of treatment.
