In this internal medicine treatment bed, because the isolation pad 5 comprises the range upon range of multilayer barrier film 12, in clinical application, every patient can use one deck barrier film 12 alone, because barrier film 12 closely laminates and is difficult to the aversion, can guarantee that barrier film 12 health is aseptic, reduces internal medicine treatment bed initiation cross infection's probability to minimum.

Referring to fig. 2, in the medical treatment bed, the isolation pad 5 is generally prepared by a professional manufacturer, the isolation pad 5 is formed by stacking a plurality of isolation films 12, and the isolation pad can be prefabricated by adopting the prior art, specifically, a film made of medical plastics is selected as a blank of the isolation films 12, and the blanks are sequentially stacked and arranged to reduce air trapped between adjacent layers to the maximum extent; compacting by using a die, on one hand, discharging the air which is clamped so as to enable the blanks to be attached more tightly, and on the other hand, shaping the stacked blanks so as to enable the blanks to be flat; in the compacting process, the corner of the isolation pad 5 to be adsorbed by the sucker 801 is not suitable to be squeezed by excessive pressure, so that the sucker 801 can smoothly lift the isolation film 12 from the corner; finally, the edge contour is cut by a cutting tool, and the prefabrication of the isolation pad 5 is completed. Because the isolating membranes 12 are very light and thin, the isolating membranes 12 contained in one isolating pad 5 are huge in number, so that the isolating pad 5 can meet the requirement of long-time clinical work after being installed, and does not need to be replaced frequently.

Referring to fig. 5 and 6, because the corners of the prefabricated isolation pad 5 are relatively regular, and the adjacent isolation films 12 are tightly attached, a worker cannot easily separate one corner of the isolation film 12 at the uppermost layer from the isolation pad 5, but when the isolation pad 5 is adsorbed by the suction cup 801 and pulled upwards, the traction force is only applied to the isolation film 12 at the uppermost layer of the isolation pad 5, and the attaching force between the isolation films 12 at the corners is relatively weak, so that the corners of the isolation films 12 can be separated from the isolation pad 5 in the upward moving process of the suction cup 801; then, the corner of the separated isolating membrane 12 is manually held, so that the isolating membrane 12 can be easily and quickly torn off; compared with the prior modes of sterilizing on site or replacing a disposable bed sheet and the like, the mode adopted by the internal medicine treatment bed can be operated more conveniently and rapidly, and the medical efficiency cannot be obviously adversely affected.

As shown in fig. 3 and 6, in the internal medicine treatment bed, the crank device 8 has two functions, namely, the crank device can be used for adjusting the inclination angle of the movable bed plate 3 to meet the treatment requirement, and can be used for separating the isolating membrane 12 from the isolating pad 5 after simple position adjustment, so that two purposes are achieved, and the utilization rate of the crank device 8 is greatly improved; in the initial state, most of the long arm 806 is accommodated in the lumen of the input shaft 9, and the crank device 8 is very small and does not significantly increase the volume of the medical treatment couch.

As shown in fig. 1 and 2, it is very important to keep the patient in a relaxed and comfortable state during the clinical treatment; the isolation cushion 5 has soft characteristic, so that a certain comfortable feeling can be brought to the lying of a patient; in order to further improve the comfort of the medical treatment bed, the movable bed plate 3 is provided with a headrest part 11 protruding upwards, the fixed bed plate 1 is provided with an oval breathing counter bore 13, and the isolation pad 5 is pre-provided with a bulge part 4 matched with the headrest part 11 and a hole 6 matched with the hole 6; the head rest portion 11 provides support for the head of the patient when the patient is lying on his back, and the face of the patient is placed in the breathing counter bore 13 when the patient is lying on his stomach.

As shown in fig. 3 and 5, in the medical treatment bed, a clamping seat 14 is provided at the front end of the bed body 10, and a U-shaped groove 141 is provided on the clamping seat 14; when the long arm 806 is rotated upwards to the notch 901, the long arm 806 is perpendicular to the input shaft 9, and the long arm 806 is located in the vertical direction, the long arm 806 is just clamped in the U-shaped groove 141 of the clamping seat 14; in the process of manually driving the handle 804 to move down to enable the suction cup 801 to suck the isolation pad 5, the clamping seat 14 can prevent the crank arm from swinging around the input shaft 9, so as to ensure that the suction cup 801 can firmly suck the isolation pad 5.
