Detailed Description
The invention will be further described with reference to the following examples and the accompanying drawings, in which it is to be understood that the following examples are illustrative only and are not intended to limit the invention.
As shown in FIG. 1, a conventional CT apparatus generally includes a nuclear magnetic examination device 3, a CT examination bed 2, and a bed frame 1. The bed frame 1 is used for supporting the CT detection bed and is provided with a driving structure which can drive the CT detection bed 2 to move towards the nuclear magnetic detection device 3. In some cases the bed frame 1 is also movable towards the nuclear magnetic detection unit 3. The nuclear magnetic detection device 3 can rotate 360 degrees around the circumference, so that the affected part of the patient can be scanned by 360 degrees.
Referring to fig. 2, a schematic structural diagram of the CT examination bed of the present invention is specifically shown. The CT-examination bed 2 comprises a bed portion for supporting a patient. Bottom slideways 21 are respectively arranged on the two sides (namely the two sides in the width direction) of the bed body along the length direction (the height direction of a patient) of the bed body below the bed body. The two ends of the bottom slide 21 are fixed to the two ends of the bed respectively, for example, by means of screws or welding. The bottom slide 21 has a hollow slide 22 so that the lower slide 33 can move unrestrictedly in the hollow slide 22 from one end of the bed to the other.
Referring also to fig. 4, the mounting arrangement of the bottom slide 21 and the lower slide 33 is shown in detail. It can be seen that the lower slide 33 traverses two symmetrically arranged bottom runners 21. The two sliding rods 33 are respectively arranged at the front end and the rear end of the CT detection bed, and the two sliding rods 33 are symmetrically arranged. Only one of which is described below for simplicity.
Guardrails are respectively arranged on the two sides (namely the two sides in the width direction) of the bed body along the length direction (the height direction of a patient) of the bed body above the bed body, and each guardrail is provided with a hollow upper slideway 23. The two ends of the guardrail are respectively fixed to the two ends of the bed body, for example, by means of screw fixation or welding. The two ends of the guard rail are each arc-shaped so that the upper slide bar 43 can move unrestrictedly in the upper slide 23 from the bottom of the arc-shaped structure of the guard rail at one end of the bed towards the other end of the bed.
Referring also to fig. 3, the mounting arrangement of the upper run 23 and the upper slide bar 43 is shown in detail. The upper slide bar can be seen to traverse two symmetrically disposed upper runners 23. The two slide bars 43 are respectively arranged at the front end and the rear end of the CT detection bed, and the two slide bars 43 are symmetrically arranged. Only one of which is described below for simplicity.
The two ends of the CT detection bed 2 in the length direction are respectively provided with a protection mechanism, namely a front end protection mechanism and a rear end protection mechanism. The two protection mechanisms have the same structure and are symmetrically arranged. The structure of the front end protection mechanism of the CT examination bed 2 will be described below as an example. The protection mechanism comprises a lower protection cover roll 3 and an upper protection cover roll 4, wherein the lower protection cover roll 3 and the upper protection cover roll 4 are respectively fixed at the end parts of the bed body through support rods 32 and 42. The lower shield roll 3 and the upper shield roll 4 have the same structure. The upper protective roll 4 and the lower protective roll 3 are respectively provided with the radiation- proof cloth 41,31 which can be unfolded and folded, one end of the radiation- proof cloth 41,31 is respectively fixed on the reel of the upper protective roll 4 and the lower protective roll 3, and the other end is respectively fixed on the upper sliding rod 43 and the lower sliding rod 33, so that the radiation- proof cloth 41,31 can be unfolded or folded when the upper sliding rod 43 and the lower sliding rod 33 move. When the bed is installed, the upper sliding rod 43 is inserted from between the two upper slideways 23 to the outer side of the bed body, so that the upper sliding rod 43 can move freely between the two upper slideways 23. Similarly, the lower slide bar is inserted from between the two lower slides 21 to the outside of the bed body, so that the lower slide bar 33 can move freely between the two bottom slides 21.
Each protection mechanism further comprises two side protection cover rolls 5 which are respectively arranged at two sides of the guardrail and positioned at the end part of the CT detection bed. Namely, the two side protective cover rolls 5 of the front protective mechanism are positioned at the front end of the CT detection bed, and the two side protective cover rolls 5 of the rear protective mechanism are positioned at the rear end of the CT detection bed. The side shield roll 5 includes a reel, a radiation protective cloth 51, and a side slide 53. Wherein the side sliding rods 53 can move back and forth along the outer sides of the upper slide 23 and the bottom slide 21, thereby driving the radiation protection cloth 51 on the side shield roll 5 to be unfolded or retracted.
The lower shield roll 3 and the upper shield roll 4 and the side shield roll 5 are provided with coil spring mechanisms at their reels. The radiation- proof cloth 31,41,51 is stretched by the pulling of the external force, and when the external force disappears, the coil spring mechanism can recover the radiation- proof cloth 31,41, 51. The spring coiling mechanism adopts a conventional spring coiling mechanism, such as the spring coiling mechanism of a tape measure, as long as the radiation-proof cloth can be recovered.
Referring to fig. 7, the upper slider 43 moves back and forth in the upper slide, and a rope 431 is provided on the upper slider 43, and rope outlets 29,281 are provided on the top in the back and forth direction of the upper slide, respectively. That is, the rope 431 of the upper slide bar 43 of the front guard mechanism extends from the rope outlet 282 at the rear top of the upper run, and the rope 431 of the upper slide bar 43 of the rear guard mechanism extends from the rope outlet 29 at the front top of the upper run. The rope exit 29,281 is located at the top of the upper run so that the rope itself does not impede the movement of the upper slide bar. If placed on the side of and below the upper run, it is apparent that there is an obstruction to the movement of the slide bar.
Referring to fig. 8, the lower slide bar 33 moves back and forth in the bottom slide way, a pull rope 331 is provided on the lower slide bar, and rope outlet holes 25,27 are provided on the front and rear end surfaces of the bottom slide way 21, respectively, wherein the pull rope 331 of the lower slide bar 33 of the front end protection mechanism extends from the rope outlet hole 27 of the rear end surface of the bottom slide way 21, and the pull rope of the lower slide bar 33 of the rear end protection mechanism extends from the rope outlet hole 25 of the front end surface of the bottom slide way 21. Rope holes 25,27 are provided at the ends of the bottom runner so that the rope itself does not hinder the movement of the lower runner.
Under the pulling of the pull rope, the upper sliding rod and the lower sliding rod move back and forth, so that the radiation- proof cloth 31 and 41 of the lower protective cover roll 3 and the upper protective cover roll 4 are unfolded, and after the pulling force disappears, the radiation- proof cloth 31 and 41 is retracted under the acting force of the coil spring.
With further reference to fig. 4-5, a plurality of motors 71-78 and an electronic control unit ECU are respectively disposed on the lateral sides of the bed body of the CT examination bed, and only one of the motors is used, and all the motors are connected to the electronic control unit ECU.
Referring to fig. 10, each motor has a winding. Fig. 10 illustrates one of the motors 71, which includes the motor 71, a coil 711 for receiving the pull rope 331 of the lower slider bar 31.
In one embodiment, both ends (both ends in the width direction) of the lower slide bar 31 of the front end guard mechanism are provided with pulling ropes 331, which respectively extend from the rope outlet holes 27 in the rear end surface of the bottom slide rail 21 and are respectively wound around the windings of one motor. In the reset state, the lower slide bar 31 is located at the front end of the CT examination bed, and is not acted by the pull rope or the coil spring of the lower shield roll 3, so that it will be in the "rest state". When the motor rotates, the pulling rope 331 is wound on the winding 711, so that the pulling rope 331 is tightened, and the lower sliding rod 31 moves along the bottom slideway 22 under the action of the pulling rope, so as to drive the radiation-proof cloth to move, and finally cover the lower part of the CT detection bed.
Similarly, under the driving of the motor, the upper slide bar 43 will move along the upper slide way 23 to drive the radiation-proof cloth 41 to cover the top of the CT detection bed.
Furthermore, referring to fig. 9, the side shield rolls 5 are fixed to the sides of both ends of the CT examination bed by supports, i.e., one CT examination bed 2 has four side shield rolls 5. One end of the side slide bar 53 of the side shield roll 5 is fitted into the end surface groove of the lower slide bar 33 and fixed by the screw 6, but may be fixed by another method. The side of the upper end of the side slide 53 has an arc-shaped slot adapted to the upper slide 43. When the motors rotate, the upper sliding rod 43 and the lower sliding rod 33 are driven to move. Because the upper slide bar 43 is located in front of the side slide bar 53, the upper slide bar will abut against the upper arc-shaped groove of the side slide bar 53 when moving, and the side slide bar 53 is driven to move. When the operation is finished, the locking force of the motor disappears, for example, a stepping motor is adopted. At this point the upper slide 43, the lower slide 33 will be returned under the force of the coil spring, so that the upper slide 43 will return to the curved bottom of the guard rail since the guard rail has curved ends and since there is an articulation between the upper slide 43 and the side slide 53. This does not cause the radiation-shielding cloth 41 to cover the end of the CT table. The person to be examined can freely get on and off the bed from both ends of the CT examining table. This is a significant improvement over the prior art which necessitates "drilling" into the CT table from the end.
Meanwhile, the CT examination bed can be covered in 360 degrees in all directions due to the adoption of the protection mechanism, so that the defect that only the upper part of the CT examination bed can be protected in the prior art is overcome, and when the CT detection device rotates to the lower part and the side part of the CT examination bed, the lower part and the side surface of a person to be examined can also be protected.
The invention also provides an operation method of the self-adaptive CT equipment, which comprises the following steps:
step S1: the ECU controls the motor to rotate, so that an upper sliding rod and a lower sliding rod of the front end protection mechanism are driven to move towards one end of the CT examining table;
before this step, the installation of the front-end guard mechanism and the rear-end guard mechanism needs to be completed first. Namely, the upper protective cover roll, the lower protective cover roll and the side protective cover of the front end protective mechanism and the rear end protective mechanism are respectively fixed at the corresponding positions of the CT examining table. And then, respectively extending the upper sliding rod and the lower sliding rod from the middle of the CT examining table to the upper slideway and the lower slideway at the two sides to finish the installation of the upper sliding rod and the lower sliding rod. And finally, fixing the side sliding rods in the fixing grooves on the end faces of the lower sliding rods. Thus, the installation of the front and rear end guard mechanisms is completed.
Step S2: the ECU controls the motor to rotate, so that an upper sliding rod and a lower sliding rod of the rear end protection mechanism are driven to move towards the other end of the CT examining table;
the front and rear end guard mechanisms in steps S1 and S2 may be operated simultaneously, and the motors may share one ECU or may use separate ECUs. The ECU has a remote control function, for example, a medical staff member can individually remotely control the ECU. The ECU may also be connected to a control system of the CT apparatus.
Step S3: the ECU controls the motor to stop rotating and controls the motor to be in an electromagnetic locking state or a physical locking state, for example, a physical locking mechanism is adopted;
step S4: the CT examining table extends to the CT detecting device to carry out CT examination to the person to be examined.
In steps S3 and S4, the medical staff can position the location where the person to be examined needs to be examined as needed, and then the front and rear protection mechanisms are respectively operated, so that the radiation-proof cloth covers the location where the person to be examined does not need to be examined. For example, when the heart of a person to be examined is examined, the front protection mechanism needs to be moved to the upper part of the heart, and the rear protection mechanism needs to be moved to the lower part of the heart, so that all the ring surfaces of other parts of the human body except the ring surface of the heart are covered by the radiation-proof cloth, and thus the person is not damaged by additional radiation.
Step S5: after the CT examination is finished, the CT examination bed is withdrawn from the CT detection device;
step S6: the ECU controls the motor to release the locking state, and the upper slide bar, the lower slide bar and the side slide bar are retracted under the action of the protective cover rolls respectively.
The upper slide bar will be retracted to the bottom of the arc-shaped guardrail of the guardrail, at which time the person to be examined can easily get on and off the bed without having to drill out of the protective cover.
The protection mechanism of the invention can not obstruct the action of the person to be checked. And the structure is simple and easy, easy operation can carry out 360 degrees protections to the personnel of being examined, and low cost can carry out very simple transformation to current CT bed and can accomplish.
Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that the present invention is not limited to the specific embodiments, but rather, various modifications, alterations, and substitutions can be made without departing from the spirit and scope of the present application.
