For some patients in hospital and patients who are inconvenient to recuperate and move at home, the nursing staff is required to place a bedpan on the bed for the patients to solve the problem of defecation because the patients cannot get up to go to the toilet to relieve the bowels under the physical condition. In the prior art, the most common bedpan used in the hospital bed is a low and open bedpan, which has a simple structure, but the height of the bedpan in the vertical direction is higher than that of the bed surface when the bedpan is placed on the bed, and the patient needs to arch the waist to support the buttocks on the bedpan for defecation when using the bedpan. Although the medical bedpan with the traditional structure has simple structure, the medical bedpan has the following defects when in use:

1) the defecation of the patient is difficult because the waist of the patient is not supported or is difficult to carry out by the weak patient because the actions of arching the waist and lifting the buttocks are required to be carried out with enough supporting force. Therefore, it is a research focus to develop a medical bedpan which can relieve the bowels in both the lying posture and the sitting posture in a natural state;

2) even if a patient can freely sit on the bed to relieve the bowels, the height of the bed pan is too low, so that the feet of the patient are seriously bent after sitting on the bed, the patient feels extremely uncomfortable, and particularly, the feet of the patient become numb when the bed pan is used for a long time, and the use comfort is poor;

3) above-mentioned traditional medical bedpan does not have from washing function, function singleness, and patient still needs oneself or nursing staff to clean the work after finishing defecating, and patient if weak then cleans the work and can't accomplish alone and need nursing staff's help, has the awkwardness when nursing staff and patient are the opposite sex mutually.

To the defect that traditional medical bedpan exists, bedpan of various structures has appeared in the existing market, for example the chinese utility model patent that the publication number is CN201943165U discloses a sit and crouch dual-purpose bedpan, and it includes the bedpan support, establishes a defecation passageway on this bedpan support, and this bedpan support bottom corresponds the defecation passageway and is equipped with the bedpan body that sets up with bedpan support separation, and this bedpan body is equipped with lid and plug-type urine and holds in the palm the front end and be an arc body, and various electrical apparatus establish about to and in the cavity of back. The bedpan can realize dual purposes of sitting and lying and improves the use comfort level, and meanwhile, the bedpan can also make a nurse invisible from end to end, so that the bedpan is more humanized. But when it is placed and uses in the bed, height in vertical direction still is higher than the bed surface, still has the defect of above-mentioned traditional medical bedpan, and this kind of bedpan is independent separately for using alone, each other with the sick bed simultaneously, not only occupation space and lose easily.
