Detailed Description
Referring to fig. 1-4, the invention discloses an internal medicine examining bed, which comprises a bed body 1, a protective cushion 14 and a film uncovering and recycling assembly; the bed body 1 consists of a bed board and a plurality of bed legs for supporting the bed board, and the bed body can also be directly selected from the existing internal medicine examining bed; the protective cushion 14 is laid above the bed board for a patient to directly lie down, and is formed by sequentially laminating and compacting multiple layers of isolation films 15 with the same shape, and the isolation films 15 adjacent to each other up and down can be tightly attached due to the fact that air does not exist between the isolation films 15, so that the protective cushion 14 is relatively stable as a whole, and in the clinical use process, the isolation films 15 in the protective cushion 14 are not easy to move relatively, and the isolation film 15 on the uppermost layer cannot be separated automatically; the film uncovering recovery assembly comprises a recovery box 13 and a film uncovering mechanism, wherein the upper end of the recovery box 13 is provided with a box opening 8, and the film uncovering mechanism comprises a supporting seat 11, a spiral arm 5, a sucker 4, a resetting device 10 and a vent valve 9; the support seat 11 can be supported by the bed body 1, the recovery box 13 or a special support device, and is fixed relative to the bed body 1; one side of the front end of the spiral arm 5 is fixedly connected with the sucking disc 4, and the tail end of the spiral arm 5 is hinged and supported by the supporting seat 11, so that the spiral arm 5 has a rotary stroke; the rotary arm 5 rotates towards the stroke terminal direction, so that the sucker 4 falls on the upper side of one corner of the protective pad 14 and presses out air in the sucker 4, namely the sucker 4 firmly adsorbs the isolating membrane 15 on the uppermost layer of the protective pad 14; when the rotary arm 5 is positioned at the initial end of the stroke, the sucking disc 4 is positioned right above the box opening 8 of the recovery box 13; the reset device 10 acts on the tail end of the radial arm 5 and can drive the radial arm 5 to rotate towards the stroke starting end to reset and keep the stroke starting end; the vent valve 9 has two states of on-off, the internal gas path of the vent valve is connected between the inner cavity of the sucker 4 and the outside, the on-off state of the vent valve is influenced by the position of the spiral arm 5, and the inner cavity of the sucker 4 is communicated with the outside only when the spiral arm 5 is positioned at the initial end of the stroke; based on the above structure, when the external force drives the swing arm 5 to rotate towards the stroke terminal direction, the suction cup 4 can adsorb and fix the isolation film 15 on the uppermost layer of the protection pad 14, after the external force is removed, the reset device 10 will drive the swing arm 5 to rotate towards the stroke starting end direction, at this time, one corner of the isolation film 15 adsorbing the uppermost layer is gradually lifted by the suction cup 4, so that the isolation film 15 is gradually uncovered and finally uncovered, when the swing arm 5 is reset to the stroke starting end, the isolation film 15 is positioned right above the box opening 8 of the recycling box 13, the vent valve 9 communicates the inner cavity of the suction cup 4 with the outside, the adsorption effect of the suction cup 4 is gradually weakened along with the entering of air, and the finally uncovered isolation film 15 falls into the recycling box 13.
The working principle of the internal medicine examining table is as follows:
as shown in fig. 1, 3 and 4, after the patient is examined, an external force is applied to drive the swing arm 5 to rotate towards the stroke terminal direction until the suction cup 4 is tightly pressed on the upper side of one corner of the protection pad 14, and because the air in the suction cup 4 is squeezed and exhausted and the vent valve 9 is in a disconnected state, the suction cup 4 and the isolation film 15 on the uppermost layer of the protection pad 14 are sucked together; after the external force is removed, the rotating arm 5 is driven by the reset device 10 to rotate towards the direction of the initial stroke, although the isolation film 15 at the uppermost layer is tightly attached to the main body of the protection pad 14 at the lower side, however, the corner of the isolation film 15 is very easily separated from the main body of the protection pad 14 by the upward force, and the initial period of the upward movement of the suction cup 4, the force applied to the isolation film 15 by the suction cup 4 is vertical and uniform, so that the suction force generated by the suction cup 4 can open a corner of the isolation film 15 at the uppermost layer, then, with the lifting of the radial arm 5, the suction cup 4 pulls a corner of the isolation film 15 to move obliquely upwards, although the force is applied to the lower side of the portion 3 of the separation film 15 to be sucked, the direction of the force tends to overlap the end surface of the suction pad 4, so that the separation film 15 does not separate from the suction pad 4, the separating film 15 can thus be gradually peeled off until it is removed, i.e. the separating film 15 is completely separated from the protective pad 14; after the swing arm 5 is reset and rotates to the initial end of the stroke, the inner cavity of the sucker 4 is communicated with the outside through the vent valve 9, air enters the sucker 4, the adsorption effect on the isolating membrane 15 is gradually reduced, the isolating membrane 15 is separated from the sucker 4 and falls into the recovery box 13 below the sucker, and the recovery of the used isolating membrane 15 is realized; finally, the top layer of the protective pad 14 is a clean and sanitary new isolation film 15 for the next patient, and the rotating arm 5 is maintained at the beginning of the stroke under the action of the resetting device 10, so that no obstacle is caused to the examination operation.
In clinical application, each patient can use one layer of isolating membrane 15 alone, because isolating membrane 15 is closely attached and is difficult to shift, can guarantee that isolating membrane 15 is sanitary aseptic before using, reduces the possibility that internal medicine inspection bed causes cross infection to minimum.
Referring to fig. 2, in the medical examination bed, the protective pad 14 is generally prepared by a professional manufacturer, the protective pad 14 is formed by laminating a plurality of isolation films 15, and the protective 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 15, and the blanks are sequentially laminated 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 protective pad 14 to be adsorbed by the sucker 4 is not suitable to be squeezed by excessive pressure, so that the sucker 4 can smoothly lift the isolation film 15 from the corner; finally, the edge contour 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 large, so that the protection pad 14 can meet the requirement of long-time clinical work after being installed, and the protection pad does not need to be frequently replaced.
As shown in fig. 1 and 3, in the medical examination bed, a recovery box 13 is used for recovering a used separator 15, and a side door 12 is provided on one side of the recovery box 13 in order to facilitate removal of a waste separator therein.
As shown in FIG. 2, in clinical medical examination, the relaxation state of the patient is generally required to ensure the objectivity of the examination result, so the comfort of the medical examination bed is also extremely important; because the protective cushion 14 has soft characteristics, certain comfort is brought to the patient when the patient lies; for the comfort level of this internal medicine examination bed of further improvement, bed body 1 on be equipped with an upwards convex headrest portion 6, protection pad 14 prefabricated have be used for with the upper bend portion 7 of headrest portion 6 laminating.
As shown in fig. 2, when a patient is clinically examined by using the medical examination bed, the body of the patient can be in contact with the outer side of the bed body 1 in the process of getting on and off the bed, and in order to improve the omnibearing protection effect of the medical examination bed, the invention has the following improvements: a downward bending part 2 which is bent downwards and is used for covering the outer side of the bed edge is prefabricated on the outer side of the protective cushion 14, the rotary arm 5 rotates towards the stroke terminal direction to enable the suction cup 4 to fall on the upper side of a corner part of the protective cushion 14, and the corner part is positioned on the inner side of the protective cushion 14; the outer side refers to the side of the medical examining table close to the patient during the use process, and the opposite side is the inner side.
Referring to fig. 1, 3 and 4, in the medical examination bed, the rotary arm 5 rotates to drive the suction cup 4 to lift up, so as to lift the isolation film 15 at one corner, and then gradually uncover the isolation film 15 until uncovering, in the process, the motion track of the suction cup 4 has a substantial influence on the smoothness and the required force for uncovering the isolation film 15; in the invention, the rotary arm 5 rotates towards the stroke terminal direction to enable the sucker 4 to fall on the upper side of one corner of the protective pad 14, when the rotary arm 5 is positioned at the stroke starting end, the sucker 4 leans against the upper side of the other corner of the protective pad 14, the two corners are opposite corners, namely, a vertical plane where the motion track of the sucker 4 is positioned is close to and tends to be parallel to a diagonal line of the protective pad 14; based on the structure, in the lifting process of the spiral arm 5, one corner of the isolation film 15 is firstly lifted by the sucker 4, then the corner of the isolation film 15 is pulled 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 mutual stress of the isolation film 15, the sucker 4 and the spiral arm 5 is smaller and more stable.
As shown in fig. 1, in the medical examination bed, the suction cup 4 can generate sufficient suction force to 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 sufficient suction force to the isolation film 15, the region of the corner of the isolation film 15, which is sucked by the suction cup 4, is provided with a thickened and hardened sucking part 3, and when the sucking part 3 is sucked by the suction cup 4, excessive deformation is not generated, so that the suction cup 4 can generate stable and sufficient suction force to 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 stable and tight contact between the isolation film 15 and the sucker 4 can be ensured, and the adsorption effect of the sucker 4 on the isolation film 15 is improved.
Referring to fig. 1, 3 and 4, in the above medical examination, the vent valve 9 has two states of on-off, which is in an off state during the film uncovering process, so that the inner cavity of the suction cup 4 is in a sealed state, thereby stably adsorbing the isolation film 15, and when the swing arm 5 is located at the beginning of the stroke, the vent valve 9 is in an on state, so that the inner cavity of the suction cup 4 enters air and gradually loses the adsorption effect on the isolation film 15; for the above purpose of setting the vent valve 9, the prior art has various embodiments, but in order to make the structure of the vent valve 9 simpler and more stable in operation, it is preferable to adopt the following structure:
