Description

Diagnosis bed for anorectal department Technical Field The invention relates to the field of examination beds, in particular to an examination bed for anorectal departments. Background In the anorectal examination, patients usually need to adopt a lateral position, a knee chest position or a lithotomy position. Wherein, the lateral position is the most commonly used body position for finger examination, anoscopy and partial minimally invasive treatment. In the prior art, conventional diagnostic beds or specialized anorectal beds often only provide planar support. When a patient adopts a lateral position, the legs above the patient are required to be suspended or overlapped in a crossing way by lacking support, which is very easy to cause leg ache, unstable body gravity center and swing of the body position of the patient, so that the examination precision and operation safety of doctors are affected, and in order to stabilize the lateral position, a special leg bearing device (such as a simple bracket or a concave supporting table) is additionally arranged on a diagnosis bed in part of the prior art for bearing one limb of the patient above. Considering sanitation and safety, a disposable pad sheet or a protective film is generally paved on a bed surface clinically, a fixed-length rolling mode is generally adopted by a traditional automatic rolling mechanism, however, in practical clinical application, because limb sizes (such as leg thicknesses) of different patients are obviously different, the inflation degree required by an air bag is also different for realizing stable clamping, and as a result, when the legs of the patients are thinner, the air bag needs to be greatly inflated to reduce the clamping space, and at the moment, the protective film covered on the surface of the air bag can be deeply pressed into a U-shaped groove, so that the space occupation path of the protective film is obviously increased; Under the working condition of dynamic change, the traditional fixed-length winding mechanism has the defect that if the uniform winding length is adopted, the winding amount is insufficient for completely withdrawing the old film which is stretched and deformed under the working condition of the air bag after the air bag is greatly expanded, so that the old film remains in an inspection area, the risk of cross infection is generated, and the actual film consumption caused by the deformation of the air bag each time is difficult to accurately confirm. Disclosure of Invention The invention aims to provide a diagnosis bed for anorectal department, which solves the problems, and the specific technical scheme is as follows: a diagnostic bed for anorectal surgery comprising: a bed body main frame; the bed surface unit is arranged on the bed body main frame; The clamping mechanism is arranged on one side of the bed surface unit and used for supporting and fixing a single-side leg of a patient during lateral position examination; The sanitary protection assembly comprises a roll feeding mechanism and a rolling mechanism which are respectively arranged in two sides of the clamping mechanism, a disposable protection film is wound on the roll feeding mechanism, and the disposable protection film spans the surface of the buffer air bag and extends to the rolling mechanism; And the control system is connected with an air outlet quantity detection mechanism at the air outlet end of the buffer air bag, calculates the tensile deformation quantity of the buffer air bag on the disposable protective film in an expansion state according to the air outlet quantity data fed back by the air outlet quantity detection mechanism, and corrects the stepping length of the single-time recovery protective film of the winding mechanism based on the deformation quantity. As one of the improvement of the technical scheme, the air cushion air bag further comprises an air inflation power source arranged in the U-shaped groove base, and the air inflation power source is connected with the air cushion air bag through an air passage pipeline. As one of the improvements of the above technical scheme, the device further comprises a control panel arranged at the top of the clamping mechanism, wherein the control panel is electrically connected with the control system and is used for inputting body type parameters of a patient or manually adjusting the inflation pressure of the buffer air bag. As one of the improvements of the above technical scheme, the control panel is provided with a one-key film-changing key, so that after the one-key film-changing key is started, the control system controls the buffer air bag to perform the air exhaust action first, and after the air output detection mechanism completes detection, the winding mechanism is driven to perform the winding action with length compensation. As one of the improvements of the above technical solutions, the control panel is further integrated with a display screen for displaying
