Abstract
The invention discloses an examination couch with a protective device, which comprises a horizontal part and a vertical lift part, wherein a bottom cover is arranged under the horizontal part, the edge of the upper part of the bottom cover is provided with touch sensors, each touch sensor is connected with a drive motor of the vertical lift part so as to control the rotation of the motor, and the touch sensors are microswitches. The examination couch with the protective device, which is provided by the invention, is provided with the touch sensors at the edge of the upper part of the mobile bottom cover. The bottom cover can be lifted so as to trigger the touch sensors when the design resistance of the touch sensor overcomes the gravity of the bottom cover, and the touch sensors immediately send blackout signals to the vertical motor to stop the rotation of the motor so as to stop the vertical motion of examination couch, so that the examination couch as well as devices and maintenance staffs capable of being pressed by the examination couch can be protected to the maximum extent. Moreover, the examination couch with the protective device has the advantages of lower design cost, simplicity and reliability in function, and easiness in maintenance.
Description
Technical field
The present invention relates to a kind of examinating couch, relate in particular to a kind of examinating couch with protector.
Background technology
Armarium, comprises MR CT, PET-CT, and linear acceleratoies etc. all need examinating couch to carry out supporting patient, and need to realize the motion of each degree of freedom of examinating couch.In sick bed horizontal component bottom, having space is greatly that sick bed institute is unwanted, in process of clinical application, probably have other equipment, such as wheelchair or small auxiliary equipment, the equipment such as removable respirator can be pushed sick bed horizontal component bottom accidentally, even in maintenance process, also having maintainer may be in sick bed horizontal component bottom, if at this moment operator carry out downward the moving both vertically of sick bed, cause possibly the damage of sick bed itself and oppressed equipment, also may cause oppressed maintainer to be hurt.Therefore for bed motion in vertical direction, wish that sick bed, doing while moving vertically downward, if while running into unexpected resistance, needs timely stop motion, to protect sick bed not to be damaged, also can protect the object or person person who is oppressed by sick bed to preserve from simultaneously.
The existing sick bed for CT or MR examinating couch protection design mainly realizes the bed board defencive function that moves both vertically by motor current-limiting, when sick bed is done downward moving both vertically, surprisingly run into other equipment or maintainer still when sick bed bottom, by Electric Machine Control, responding to electric current that sick bed additional movements resistance causes increases to trigger current-limiting protection function and makes sick bed stop motion, this design has needs the even thousands of newton's of the resistance of trigger protection function several hectonewtons of excessive common needs resistance ability trigger protection function, existing easily makes this province of sick bed equipment damaged and that accidentally oppressed by sick bed damaged, or the risk that maintainer is injured.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of examinating couch with protector; very little to encountering the requirement of blockage resistance; as long as can overcome just energy trigger protection function of bottom gravity; equipment and the maintainer protecting to greatest extent sick bed and may be oppressed by sick bed; and simple in structure; design cost is also lower, easily maintenance test.
The present invention solves the problems of the technologies described above the technical scheme adopting to be to provide a kind of examinating couch with protector; comprise horizontal part and vertical lift portion; wherein; described horizontal part below is provided with bottom; described bottom top edge is provided with touch sensor, and the drive motors of described touch sensor and vertical lift portion is connected and controls its stall.
Further, described vertical lift portion comprises expansion bracket, screw mandrel and the drive motors that is double shear knife structure, described expansion bracket is fixed between horizontal part and base, on described expansion bracket, be provided with leading screw, one end of described leading screw is connected with drive motors by gear-box, the other end is provided with the screw thread matching with the nut that is fixed on the overlapping place of expansion bracket, and cover is connected in described nut.
Further, described expansion bracket comprises two fixing feet and two movable legs that are arranged on the same side, and one of them fixing feet is fixed on horizontal part, and another fixing feet is fixed on base, a slip foot is fixed on horizontal part by guide rail, and another slip foot is fixed on base by guide rail.
Further, described touch sensor is microswitch.
Further, the edge, two long limits of described bottom is step-like, the lower edge of described horizontal part shell bends inwards and forms the kink together with offseting with bottom step, and described touch sensor is arranged on the kink of horizontal part shell, and operating spring is close to the top edge of bottom.
Further, described touch sensor number is four, divides four corners that are laid in bottom.
Further, described touch sensor number is two, divides the centre that is laid in two long limits of bottom.
Further, described touch sensor number is two, divides and is laid in place, two diagonal angles of bottom.
Further, described touch sensor number is three, two two ends of being located at a long limit of bottom, and another is located at the centre on another long limit of bottom.
Further, when touch sensor change of state, described drive motors carries out reverse drive until microswitch reverts to original state.
The present invention contrasts prior art following beneficial effect: the examinating couch with protector provided by the invention, by touch sensor being set in mobilizable bottom top edge, as long as the design resistance of touch sensor overcomes bottom gravity, thereby all can being popped up, bottom triggers touch sensor, touch sensor is issued motor vertical power-off signal immediately and is caused motor stall immediately, thereby make sick bed stop moving both vertically, equipment and the maintainer having protected to greatest extent sick bed and may have been oppressed by sick bed, this design cost is also lower simultaneously, function is simple and reliable, and easily maintenance test.
