The embodiments herein are generally related to the field of hospital beds adapted for nursing. The embodiments herein are particularly related to hospital beds for use in the care and treatment of invalidated individuals confined to bed. The embodiments herein are more particularly related to a patient friendly hospital bed with integrated wash and toilet facility to enables the incapacitated and invalidated patients to perform bodily functions without leaving the bed.
A prime concern for hospital/nursing home staff or a caretaker/caregiver faced during the nursing of immobile and/or bedridden patients is in helping the patients in performing their day to day bodily functions at ease. In most of the cases, bedpans are used for this purpose. The use of bedpans requires movement of the patient which results in providing a discomfort to the patient and similar inconvenience to the caretaker.
Additionally, the patient has to completely depend on the caretaker to attend to their individual personal needs. Moreover, the patient such as patients with heavy weight, sometimes get injured during the process, especially when the patients are of heavy weight. This causes both physical as well as psychological trauma to the patients. This also creates immense pressure on the caretaker or nursing personnel in charge of the patient during a long durations of stay with the patient.
Moreover, the existing hospital beds mostly do not provide either the ability to perform the bodily functions or clean the patient afterward. In some hospitals, the beds are provided with a sectional opening for performing the bodily functions but a facility for subsequent removal and packaging of waste products is not provided.
Hence, there is a need for a patient friendly hospital bed with integrated toilet facility to enable the patients to perform bodily functions without leaving the bed. There is also a need for a patient friendly hospital bed to enable the patients to perform their bodily functions without any assistance from the caretakers/nursing professionals. Further, there is a need for a patient friendly hospital bed to offer a patient cleaning and waste disposal mechanism along with the facility for performing bodily functions.
