The working principle of the medical examination bed is as follows:
as shown in fig. 1, 3 and 4, after the patient is inspected, an external force is applied to drive the radial arm 5 to rotate towards the stroke end direction until the sucker 4 is tightly pressed on the upper side of one corner of the protection pad 14, and as the air in the sucker 4 is extruded and discharged and the ventilation valve 9 is in a disconnected state, the sucker 4 and the isolation film 15 on the uppermost layer of the protection pad 14 are adsorbed together; after external force is removed, the radial arm 5 rotates towards the beginning end of stroke under the drive of the reset device 10, although the isolation film 15 at the uppermost layer is tightly attached to the main body of the protective pad 14 at the lower side of the isolation film 15, the corner of the isolation film 15 is extremely easy to separate from the main body of the protective pad 14 under the upward acting force, and in addition, the acting force exerted by the sucker 4 on the isolation film 15 is vertical and uniformly distributed in the initial period of upward movement of the sucker 4, so that the suction force generated by the sucker 4 can lift one corner of the isolation film 15 at the uppermost layer, and then the sucker 4 pulls one corner of the isolation film 15 to move upwards along with the lifting of the radial arm 5, and the acting force of the isolation film 15 tends to overlap with the end face of the sucker 4 even though the lower side of the isolation film 15 at the position of the suction part 3 is stressed greatly, so that the isolation film 15 is not separated from the sucker 4, and the isolation film 15 can be gradually uncovered until the isolation film 15 is lifted off, namely the isolation film 15 is completely separated from the protective pad 14; after the radial arm 5 is reset and rotated to the beginning of the stroke, the ventilation valve 9 communicates the inner cavity of the sucker 4 with the outside, air enters the sucker 4 and the adsorption effect on the isolation film 15 is gradually reduced, and the isolation film 15 is separated from the sucker 4 and falls into the recovery box 13 below the suction box, so that the recovery of the used isolation film 15 is realized; finally, the uppermost layer of the protective pad 14 is a clean and sanitary brand new isolating film 15 for the next patient, and the radial arm 5 is maintained at the stroke starting end under the action of the resetting device 10, so that the examination operation is not hindered.
In clinical application, each patient can use one deck barrier film 15 alone, because barrier film 15 closely laminates and is difficult to shift, can guarantee that barrier film 15 is sanitary aseptic before using, will internal medicine inspection bed cause cross infection's probability to minimum.
Referring to fig. 2, in the present medical examination bed, the protection pad 14 is generally prepared by a professional manufacturer, the protection pad 14 is formed by laminating a plurality of layers of isolation films 15, and can be prefabricated by adopting the prior art, specifically, a film made of medical plastic is selected as a blank of the isolation film 15, and the blanks are sequentially laminated and placed, so that air trapped between adjacent layers is reduced to the greatest extent; compacting by using a die, discharging the clamped air on one hand, enabling the bonding between the blanks to be tighter, and shaping the blanks stacked together on the other hand to be flat; in the compacting process, the corners of the protective pad 14 to be adsorbed by the sucker 4 are not easy to be extruded by excessive pressure, so that the sucker 4 can smoothly lift the isolating membrane 15 from the corners; finally, the edge profile is cut by a cutting tool, and the prefabrication of the protective pad 14 is completed. Because the isolation films 15 are very light and thin, the number of the isolation films 15 contained in one protection pad 14 is huge, so that the protection pad 14 can meet the requirement of long-time clinical work after being installed without frequent replacement.
As shown in fig. 1 and 3, in the present medical examination bed, a recovery box 13 is used for recovering a used isolation film 15, and a side door 12 is provided on one side of the recovery box 13 in order to facilitate removal of the waste isolator inside.
As shown in fig. 2, in clinical medical examination, a patient's relaxed state is generally required to ensure objectivity of examination result, so that comfort of a medical examination table is also extremely important; since the protective pad 14 itself has a soft characteristic, it gives a certain comfort to the patient in lying; in order to further improve the comfort level of the medical examination bed, the bed body 1 is provided with an upwardly protruding headrest portion 6, and the protection pad 14 is prefabricated with an upwardly bent portion 7 for being attached to the headrest portion 6.
As shown in fig. 2, when a patient is clinically examined by using a medical examination table, the body of the patient is contacted with the outer side of the table body 1 in the process of getting on/off the table, and in order to improve the omnibearing protection effect of the medical examination table, the invention has the following improvement: the outside of the protective pad 14 is prefabricated with a downward bent part 2 which is used for covering the outside of the bed edge, and the rotating arm 5 rotates towards the stroke end direction to enable the sucker 4 to fall on the upper side of one corner part of the protective pad 14, and the corner part is positioned on the inside of the protective pad 14; the outer side refers to the side of the medical examination bed which is close to the patient in use, and the opposite side is the inner side.
Referring to fig. 1, 3 and 4, in the present medical examination bed, the swing arm 5 drives the suction cup 4 to lift by rotation, one corner of the isolation film 15 is lifted, and then the isolation film 15 is gradually lifted until being lifted, in the above process, the motion track of the suction cup 4 has a substantial influence on the smoothness and the required strength of the lifting of the isolation film 15; in the invention, the rotation of the radial arm 5 towards the stroke end direction can lead the suction cup 4 to fall on the upper side of one corner of the protection pad 14, the suction cup 4 is biased to lean against the upper side of the other corner of the protection pad 14 when the radial arm 5 is positioned at the stroke beginning end, and the two corners are opposite corners, namely, the vertical plane of the motion track of the suction cup 4 is close to and tends to be parallel with a diagonal line of the protection pad 14; based on the structure, in the lifting process of the radial arm 5, the sucker 4 firstly lifts one corner of the isolation film 15, then pulls the corner of the isolation film 15 to move upwards and towards the opposite corner, so that the lifting process of the isolation film 15 is smoother and more labor-saving, and the stress of the isolation film 15, the sucker 4 and the radial arm 5 is smaller and more stable.
As shown in fig. 1, in the present medical examination bed, the suction cup 4 can generate enough adsorption force on the isolation film 15, which is a necessary condition for realizing the expected film uncovering effect, in order to ensure that the suction cup 4 can generate enough adsorption force on the isolation film 15, a thickened and hardened adsorption part 3 is arranged at the corner of the isolation film 15, and when the adsorption part 3 is adsorbed by the suction cup 4, excessive deformation is not generated, so that the suction cup 4 can generate stable and enough adsorption force on the isolation film 15; in addition, the sucker 4 is properly improved or the porous vacuum sucker 4 is selected by adopting the prior art, so that the isolation film 15 and the sucker 4 can be ensured to be in stable and tight contact, and the adsorption effect of the sucker 4 on the isolation film 15 can be improved.
