Description

[0001] NON-MAGNETIC SUBSTANCE BED FOR PATIENT [0002]

The present invention relates to a non-magnetic bed for a patient, and more particularly to a non-magnetic bed for a patient which is formed of a carbon composite material and is not affected by strong magnetism of the MRI apparatus when the patient is moved to the MRI apparatus.

MRI equipment generates high frequencies in a large device that generates a magnetic field to resonate hydrogen nuclei in the body part. By resonating hydrogen nuclei, the distribution of atomic nuclei and the unique physical and chemical properties of various tissues containing nuclei can be imaged using a computer.

These MRI devices are very magnetically robust. Therefore, there should be no magnetic objects or metal objects attached to the magnet around the MRI equipment. If a metal object is carried around the MRI device, the metal object is sucked into the MRI device due to the strong magnetism of the MRI device. At this time, a metal object that is flying may cause injury to a nearby medical staff or patient. In addition, expensive MRI equipment can be damaged by metal objects. In addition, the MRI equipment must undergo a quenching process to remove the strong magnetic field and remove metal objects from the equipment. The quenching process is the removal of liquid helium from the inside of an MRI machine, which requires a lot of 2000 to 4000 liters of liquid helium to be replenished and re-filled.

Therefore, when moving a patient to an MRI device, a non-magnetic bed made of titanium or stainless steel is utilized. However, these beds are so expensive that it is difficult to have a sufficient number of non-magnetic beds in the hospital. Also, it is very heavy, and it takes a great deal of effort to carry the patient. In addition, since the patient is frequently moved from bed to bed, methods for easily moving the patient are being studied.

An invention such as Korean Patent Registration No. 10-1471624 (entitled "Functional Bed for Patient Transfer") has been proposed as a conventional technique for a patient transfer bed. However, the above-mentioned invention still has a great deal of effort for easily moving the patient, since the height of the bed is controlled or the upper body of the patient is caused.

A problem to be solved by the present invention is to use a carbon fiber material to overcome the above-mentioned problems, to manufacture a relatively inexpensive and lightweight bed, to stretch the bed from the top of the bed so that the patient can easily move when moving from bed to bed Thereby providing a separated patient bed.

In order to solve the above problems, the present invention provides a non-magnetic bed for a patient formed of a carbon composite material or aluminum, comprising: a bed part formed so that a patient can lie; A bed frame which is formed in a square shape around a side surface of the bed part and supports the bed part; An underframe formed at a lower end of the bed frame and formed to be smaller than the bed frame; A connecting part connecting the bed frame and the underframe; At least one of which is formed on a long side of the bed frame, the bed frame being formed to be adjustable in height; A wheel coupled to a lower end of the underframe and formed at an edge of the underframe; A brake unit formed at one side of the underframe and braking the wheel; And a stretcher detached from the top of the bed frame.

The connecting portion includes: a first connecting frame formed in a ladder shape; A second connection frame formed to be hingedly connected to the first connection frame; An actuator coupled to the underframe and a lower portion of the bed frame; And an actuator pedal for driving the actuator to adjust the height of the bed frame.

The bed frame includes: a stretcher fastening groove formed concavely at the upper end of the long side of the bed frame to accommodate the stretcher; And a fixing protrusion protruding in a T shape on the stretcher locking groove and having at least one protrusion.

The stretcher being configured to correspond to the shape of the stretcher locking groove to be seated in the stretcher locking groove, the stretcher frame including a hollow portion; And a stretcher body formed at an upper end of the bed portion and connected to both ends of the stretcher frame to lift the patient.

The stretcher frame includes a body frame formed in a long bar shape; A frame through hole formed in the lower end surface of the body frame and configured to allow the fixing protrusion to pass therethrough; First and second knobs formed at both ends of the body frame and bent downward; First and second switches formed on a curved inner circumferential surface of the first and second knobs; First and second fixing bars formed to overlap with lower ends of the hollow portion of the body frame and connected to the first and second switches; The first and second fixing bars are formed on the first and second fixing bars so as to be offset from the frame through holes. When the first and second switches are pressed, And two fixing holes, wherein when the first and second knobs are simultaneously pressed, the frame through-hole, the first and second fixing holes coincide with each other, and can be formed to exit the fixing protrusion.

The first and second switches may have a lower end surface bent so as to correspond to a finger shape to be gripped.

The stretcher body may include an air pocket at a location of the patient's head.

The non-magnetic bed for the patient according to the embodiment of the present invention can easily move the patient with the MRI equipment by separating the stretcher from the upper part of the bed, and is made of carbon fiber, so that the material cost is lower than that of the non- And the weight is reduced, so that the physical burden of moving the bed can be reduced.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4 attached hereto.

FIG. 1 is a perspective view of a non-magnetic bed for a patient according to an embodiment of the present invention, and FIG. 2 is a side view of a non-magnetic bed for a patient according to an embodiment of the present invention.

1 and 2, a non-magnetic bed for a patient according to an embodiment of the present invention includes a bed part 100, a bed frame 200, an underframe 300, a connection part 400, a rail part 500, A wheel 600, a brake unit 700, and a stretcher 800.

Specifically, the bed part 100 can be formed into a rectangular parallelepiped having a size such that the patient can sufficiently lie. The bed part 100 can be seated inside the bed frame 200. The bed part 100 is preferably formed of a non-magnetic material that is formed of a material such as carbon fiber and plastic or does not include a metal such as an air mattress.

The bed frame 200 is formed in a rectangular shape surrounding the side edge of the bed part 100. In addition, the bed frame 200 may include a lower pedestal (not shown) to support the bed part 100.

The underframe 300 is formed in a rectangular shape at a lower portion of the bed frame 200 and may be formed to be smaller than the bed frame 200. A wheel 600 may be formed on the lower edge of the underframe 300. It is preferable that the wheels 600 are formed in each corner, and the wheels 600 are formed in total, but the present invention is not limited thereto.

The wheels 600 may be screw-coupled to the underframe 300 so as to be removable. In addition, a spare wheel and a driver may be provided on one side of the underframe 300 so that repair can be instantly performed when the wheel 600 can not be transported due to a failure of the wheel during transportation of the patient.

The connection part 400 can connect the bed frame 200 and the underframe 300. The connection part 400 may be formed as an 'X' character by hinging the first connection frame 410 and the second connection frame 420 in a hinged manner.

The connection unit 400 may include an actuator 430 connecting the lower portion of the bed frame 200 to the underframe 300. The actuator 430 is preferably driven manually, not electrically. The actuator 430 includes an actuator pedal 440, and the height of the actuator 430 can be adjusted by driving the actuator pedal 440.

That is, when the actuator pedal 440 is depressed and released, as soon as the air flows into the cylinder, the oil passage is closed and the piston is pushed up. As a result, the height of the bed can be raised. On the other hand, if the actuator pedal 440 is kept depressed, air is introduced into the cylinder, and the flow path is maintained in an open state. Accordingly, the piston is lowered, and as a result, the height of the bed is lowered. Since this configuration corresponds to the conventional technology, it is judged that it is possible to configure the configuration so that it is not difficult for the ordinary technician.

At least one of the leg portions 500 may be formed on the long side of the bed frame 200 to prevent the patient from falling down to the side of the bed to prevent an accident. Therefore, it is preferable that the railway 500 is formed on both sides of the long side of the bed frame 200.

The ruler 500 may include a railing frame 510, a railing support 520, and a railing fixation lever 530.

The railing frame 510 may have a rectangular frame with a circular cross section. Also, at least one frame vertically connected to the middle of the rectangular frame may be formed.

The railing support 520 may be formed on the side surface of the long side of the bed frame 200. The railing support 520 includes a hole so that the railing frame 510 can be inserted into the hole.

The railing fixing lever 530 may be formed on the railing frame 510 passing through the railing support 520. When the handrail fixing lever 530 is locked, the handrail fixing lever 530 is fixed to the handrail frame 510, so that the handrail frame 510 can be caught and fixed to the handrail support base 520. When the railing fixing lever 530 is rotated, the railing frame 510 is freed and the height of the railing can be adjusted. When the position of the railing is changed and then the railing fixing lever 530 is locked again, the height is fixed and the user can adjust the railing with a desired height.

The brake unit 700 may apply a friction force to the wheel 600 to brak the bed 600 while moving the bed 600, or may fix the bed 600 in place. The brake portion 700 may include a brake pedal 710, a brake guide hole 720, and a brake pad 730.

The brake pedal 710 is formed on one side of the underframe 300 so that the bed can be operated by stepping on the foot of the carrier.

The brake guide hole 720 serves as a guiding line for moving the brake pedal 710 when the brake pedal 710 is depressed. The brake guide hole 720 is formed in an 'a' shape so that when the brake pedal 710 is stepped on the brake pedal 710, the brake pedal 710 can be maintained in a depressed state even if the brake pedal 710 is not depressed .

The brake pad 730 is formed at the lower end of the brake pedal and can be connected to the two wheels 600 so as to stop. Accordingly, when the brake pedal 710 is depressed, the brake pads 730 are lowered to frictionally contact the two wheels 600, thereby stably preventing movement of the bed.

The stretcher 800 may be formed to be detachable from the upper end of the bed frame 200. The stretcher 800 may include a stretcher frame 820 and a stretcher body 810. The stretcher 800 will be described in detail with reference to FIGS. 3 and 4. FIG.

FIG. 3 is a combined state view showing a stretcher mounting structure of a non-magnetic body bed for a patient according to an embodiment of the present invention, and FIG. 4 is a sectional view showing a detachment structure of a stretcher frame and a fixing protrusion according to an embodiment of the present invention.

3 and 4, a non-magnetic bed for a patient according to an embodiment of the present invention may include a bed part 100, a bed frame 200, and a stretcher 800. [

Since the bed part 100 is the same as that described in FIG. 1 and FIG. 2, a further explanation will be omitted.

The bed frame 200 may include a stretcher locking groove 210, a fixing protrusion 220, and a knob guide groove 230.

The stretcher fastening groove 210 may be formed concavely on both ends of the long side of the bed frame 200. The stretcher fastening groove 210 may have a rectangular cross section. Or a trapezoidal shape in which the cross section of the lower stretched light is easily inserted or removed.

The fixing protrusions 220 protrude from the lower end surface of the stretcher locking groove 210 and may be formed in a T shape. The fixing protrusions 220 are formed to be inclined from the upper surface to both sides so that when the stretcher frame 820 is engaged, the fixing protrusions 220 are slid along the inclined surface to facilitate the coupling.

The handle guide groove 230 may be formed in the side surface of the short side of the bed frame 200. The knob guide groove 230 can guide the curved handle end of the stretcher 800 along the knob guide groove 230 to be seated on the bed frame 200.

The stretcher 800 can be detached from the upper end of the bed frame 200 to easily move the patient. The stretcher 800 may be formed of a stretcher frame 820 and a stretcher body 810.

The stretcher frame 820 may be seated on both sides of the long side of the bed frame 200. The stretcher frame 820 includes a body frame 821, a frame through hole 822, first and second handles 823 and 824, first and second switches 825 and 826, First fixing holes 827 and 828, and first and second fixing holes 829 and 830.

The body frame 821 may have a rectangular cross section and may have a long bar shape with a hollow portion.

The frame through hole 822 may be formed on the lower end surface of the body frame 821. The frame through hole 822 may be formed at a corresponding position so that the fixing protrusion 220 can pass through.

The first and second knobs 823 and 824 may extend from both ends of the body frame 821 and may be curved downward. This has the effect of allowing the user holding the stretcher 800 to grasp stably.

The first switch 825 may be formed on the curved inner circumferential surface of the first handle 823. It is preferable to form the connecting portion between the body frame 821 and the first handle 823, which is a position at which the hand can be generally positioned when the user holds the handle. The second switch 826 is formed in the second handle 824 and may be formed at a position symmetrical to the first switch 825.

The first and second fixing bars 827 and 828 may be formed to overlap the lower end of the hollow portion of the body frame 821. The first fixing bar 827 is connected to the first switch 825 so that the first fixing bar 827 can move toward the first switch 825 when the first switch 825 is pressed. When the first switch 825 is released, the first fixing bar 827 can return to its original position by the action of the return spring. The second fixing bar 828 is operated by the second switch 826, and the principle thereof is the same as that of the first fixing bar 827. [

In addition, the first and second fixing bars 827 and 828 may include first and second fixing holes.

The first fixing hole 829 may be formed to have the same size as the frame through hole 822 and may be offset from the frame through hole 822 in a direction opposite to the direction of the first switch 825. When the first switch 825 is pressed to move the first fixing bar 827 toward the first switch 825, the first fixing hole 829 is also moved toward the first switch 825 so that the frame through hole 822 ). ≪ / RTI > That is, before the first switch 825 is pressed, the frame through hole 822 and the first fixing hole 829 are displaced and can not pass through the fixing protrusion 220. However, when the first switch 825 is pressed, The through hole 822 and the first fixing hole 829 can coincide with each other and can exit the fixing protrusion 220.

The second fixing hole 830 may be formed to have the same size as the frame through hole 822 and may be offset from the frame through hole 822 in a direction opposite to the direction of the second switch 826. The second fixing hole 830 is also moved toward the second switch 826 when the second switch 826 is pressed and the second fixing bar 828 is moved in the direction of the second switch 826 so that the frame through hole 822 ). ≪ / RTI > That is, before the second switch 826 is pressed, the frame through hole 822 and the second fixing hole 830 are displaced from each other and can not pass through the fixing protrusion 220. However, when the second switch 826 is pressed, The through hole 822 and the second fixing hole 830 can coincide with each other and can exit the fixing protrusion 220.

Therefore, since both the first and second fixing holes 829 and 830 are offset from the frame through hole 822, they can not be caught by the fixing protrusion 220. If only one of the first and second switches 825 and 826 is operated, there is still a fixing hole deviated from the fixing protrusion 220 due to the unactuated switch, so that the stretcher frame 820 is fixed to the fixing protrusion 220 It does not fall out. Accordingly, the stretcher frame 820 can be separated from the bed frame 200 when the first and second switches 825 and 826 are pressed at the same time. If the two persons on both sides simultaneously press the switch to lift the stretcher frame 820, the stretcher 800 will not be pulled out, thereby preventing the stretcher 800 from being separated unintentionally.

The guard portion 831 can support the upper side of the second fixing bar 828 so that the first and second fixing bars 827 and 828 do not move up and down.

The body of the stretcher 810 may be formed at the top of the bed part 100. Further, when the stretcher frame 820 is connected to both ends of the stretcher frame 820, the stretcher body 810 can support the patient and easily lift the patient.

An air pocket 811 may be provided on the upper surface of the body of the stretcher 810 where the patient's head is located. Therefore, by adjusting the amount of air introduced into the air pocket 811, the patient can lean his head comfortably. In addition, when the patient is moved to the stretcher 800, it is possible to prevent the patient's head from being impacted.

The bed frame 200, the underframe 300, the connection part 400, the rail part 500, the brake part 700, and the stretcher frame 820 of the patient according to the embodiment of the present invention may have a visa It may be formed of aluminum because it is formed of a carbon composite material which is an adult and is not affected by the strong magnetism of the MRI apparatus when the patient is moved to the MRI equipment. However, .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. .
