Abstract
Description
Patient bed with integrated X-ray detector
[0001] The present invention relates to a patient bed with an integrated X-ray detector, and more specifically, to a patient bed with an integrated X-ray detector configured to allow medical imaging examinations to be performed while the patient lies on the bed without separating the patient from the bed and moving them to a radiographic imaging device when taking radiographic images of emergency patients or patients with limited mobility.
[0002] Currently, all large hospitals are equipped with intensive care units for diseases requiring specialized treatment. The number of X-ray examinations, a basic patient test, is increasing, and in critical cases, the number of tests rises as the same patient must be examined every few hours. In particular, upon admission to the intensive care unit, examinations are performed daily using a mobile X-ray machine to continuously monitor the course of the disease.
[0003] During these X-ray examinations, patients are often examined while lying on a mattress; in this case, a medical professional lifts the patient's back to place an examination plate, such as an IP (Image Plate) or a digital X-ray detector, underneath to take an X-ray and obtain an image. Lifting the patient can be very dangerous for critically ill patients, and the task is physically demanding, exposing medical professionals to occupational diseases such as herniated discs.
[0004] In addition, since the above-mentioned test plate is positioned to come into direct contact with the patient's back, it can become a route of infection if used repeatedly on multiple patients.

[0037] FIG. 1 is an exploded perspective view illustrating an X-ray detector integrated patient bed according to one embodiment of the present invention.
[0038] Referring to FIG. 1, an X-ray detector integrated patient bed (100) according to one embodiment of the present invention includes a skeletal member (110), a mattress (120), an X-ray detecting part (130), and a shielding part (140).
[0039] The above-mentioned skeletal member (110) defines a frame forming a bed, including a frame-shaped bed frame (112) and a plurality of legs (114). Here, the bed frame (112) has a size corresponding to the specifications of the mattress (120). The bed frame (112) includes a lower panel (112a), an upper panel (112b), and a side panel (112c) connecting the lower panel (112a) and the upper panel (112b).
[0040] Specifically, the legs (114) are attached to the lower panel (112a).
[0041] The upper panel (112b) is composed of a main bar having a circular or square cross section having a length that encompasses at least the edge of the mattress (120), and an auxiliary bar attached across the main bar to support the mattress (120). That is, the main bars positioned at the edge of the mattress (120) can be formed into a frame shape (or frame shape) by welding or bolting the corner ends together.
[0042] The above side panel (112c) is connected to four sides of each of the lower panel (112a) and the upper panel (112b) to form a certain space between the lower panel (112a) and the upper panel (112b). Here, an X-ray detector is accommodated in the space formed between the lower panel (112a) and the upper panel (112b). To this end, the side panel (112c) positioned corresponding to three sides connecting the lower panel (112a) and the upper panel (112b) is configured to be completely sealed, and a first insertion hole (112c1), a second insertion hole (112c2), and a third insertion hole (112c3) are formed in the side panel (112c) positioned corresponding to one side to accommodate three X-ray detectors.
[0043] The leg (114) is positioned at the bottom of the bed frame (112) and supports it while spaced apart from the floor. In this embodiment, the leg (114) is connected to a transport frame (not given a reference numeral) having wheels (not given a reference numeral) positioned at the bottom. The leg (114) may be integrally welded to the connecting bracket of the connecting member, or it may be detachably attached by a bolt.
[0044] The above-mentioned skeletal member (110) is a wooden or resin board attached to the bed frame (112) to support and finish the mattress (120), and may further include a base plate (116) and a headboard (118). One or more base plates (116) are placed on the top of the bed frame (112) to support the mattress (120). The headboard (118) is placed on one side of the bed frame (112) in the longitudinal direction.
[0045] The above skeletal member (110) may further include a finishing plate (not shown) that is positioned on the other side and side of the bed frame (112) and wraps around a portion of the mattress (120).
[0046] The shielding part (140) is positioned on the bed frame (112) and attached to an area excluding the part corresponding to the X-ray detector to shield X-rays.
[0047] FIG. 2 is a cross-sectional view for explaining the shielding part (140) shown in FIG. 1.
[0048] Referring to FIGS. 1 and 2, the shielding part (140) is positioned in the upper and lower regions of the bed frame (112) to shield the X-ray sensor part, electronic part, etc. installed inside the X-ray detector from being deformed or damaged by X-rays. That is, X-rays can be directed only to the scintillator part of the X-ray sensor part to be irradiated, and X-rays can be blocked from the area excluding that part.
[0049] The shielding part (140) may include a lead plate (142) and a metal plate (144). The lead plate (142) is formed in a plate shape and installed to be in contact with the inner front of the X-ray detector, thereby blocking X-rays irradiated from the front side. The metal plate (144) is formed in a plate shape and attached to the rear of the lead plate (142) to fix the lead plate (142). This is because the lead plate (142) is physically soft, making it difficult to fix it to the bed frame (112) on its own, so the metal plate (144) is bonded to the lead plate (142) to fix it.
[0050] Referring again to FIG. 1, the mattress (120) is placed on the skeletal member (110). Although FIG. 1 shows the mattress (120) as being configured as a three-fold structure, it may be configured as a two-fold structure or may be configured as a non-foldable foam mattress (120).
[0051] The above mattress (120) must be made of a material that allows X-rays to pass through so that X-rays can reach the X-ray detecting unit (130) positioned at the bottom.
[0052] At this time, the material of the mattress (120) can be any material that allows X-rays to pass through, but it is preferable that it be made of TPU (Thermoplastic Polyurethane) material, which is suitable as a mattress for critically ill patients due to its high elasticity, non-toxicity, and odorless properties.
[0053] For example, the mattress (120) may include an air mattress filled with air for cushioning. Although not shown in the drawing, when using an air mattress, the mattress is divided into several sections so that air can be supplied to each section. Accordingly, the body of a critically ill patient who is unable to move can be moved little by little, which has the effect of preventing bedsores in the critically ill patient.
[0054] The air supply described above can automatically vary the air concentration in each compartment, and for the compartment located near the chest of a critically ill patient, it is desirable to supply air in a way that maintains the chest area's flatness.
[0055] As another example, the mattress (120) may include a spring made of a plastic having high strength and hardness. The plastic having high strength and hardness may include polyacetal (POM).
[0056] As another example, the mattress (120) may include a spring made of any one of copper, aluminum, carbon steel, and stainless steel. In this case, it is preferable that the copper, aluminum, carbon steel, and stainless steel be made of a thickness through which X-rays can pass.
[0057] The above X-ray detecting unit (130) includes a first X-ray detector (132), a second X-ray detector (134), and a third X-ray detector (136), and is placed under the mattress (120) to detect X-rays passing sequentially through a patient lying on the mattress (120) and the mattress (120) to acquire an image. At this time, the X-ray detecting unit (130) is shown as including the first, second, and third detectors, but the number of X-ray detectors is not limited.
[0058] FIG. 3 is a front view showing the first X-ray detector illustrated in FIG. 1. In this embodiment, the first X-ray detector is illustrated, but the second X-ray detector and the third X-ray detector may also have the same configuration.
[0059] Referring to FIGS. 1 and FIGS. 3, the first X-ray detector (132) may include a body (310), a pixel array panel (320), and a control unit (330). For example, the body (310) may be a box-shaped structure having sufficient strength and durability to support the pixel array panel (320).
[0060] The pixel array panel (320) is installed on the front of the body (310). Additionally, a handle (340) may be installed on the body (310) so that the user can hold it with their hand and use it as a portable device. However, the body (310) is not necessarily limited to the drawing, and a wide variety of structural forms may be applied to make it convenient for the user to use.
[0061] The pixel array panel (320) is installed on the body (310) and may be a type of panel element structure capable of forming an X-ray image by receiving X-rays generated from an X-ray generating device (not shown) with a plurality of pixel-shaped image sensors so as to acquire an X-ray image in DR (digital radiography) mode. The pixel array panel (320) may have an array of semiconductor elements, such as TFTs, that react to X-rays.
[0062] The above X-ray detector (132) outputs an electrical signal generated in response to X-rays from semiconductor elements within the pixel array panel (320) to the outside, transmits an X-ray image data signal to a PC, etc., and may have a power and data cable formed integrally to supply power to the X-ray detector (132).
[0063] Accordingly, the user can use the pixel array panel (320) to receive X-rays generated from an X-ray generating device into a plurality of pixel-shaped image sensors and acquire an X-ray image in DR (digital radiography) mode.
[0064] FIG. 4 is an exemplary diagram showing an X-ray inspection device equipped with an X-ray detecting unit as illustrated in FIG. 1.
[0065] As illustrated in FIGS. 1 and 4, the X-ray detecting unit (130) is a component of an X-ray inspection device, and can detect the X-ray and obtain an X-ray image as the X-ray generated from the X-ray generator (G) penetrates and irradiates the subject (S). At this time, the X-ray detecting unit (130) is formed integrally with the patient bed so that when taking a radiation image of an emergency patient or a patient with limited mobility, the patient is not separated from the bed and moved by a radiation imaging device, and the imaging examination can be performed while the patient is lying on the bed.
[0066] FIG. 5 is a block diagram illustrating an X-ray imaging device using a patient bed with an integrated X-ray detector shown in FIG. 1.
[0067] Referring to FIGS. 1 and FIGS. 5, the X-ray imaging device (400) includes a diagnostic computer (410), an interface box (420), a first X-ray detector (432), a second X-ray detector (434), a third X-ray detector (436), a first X-ray detector (132), a second X-ray detector (134), a third X-ray detector (136), a first connector (452), a second connector (454), a third connector (456), and an X-ray generator (460).
[0068] The above diagnostic computer (410) enables a doctor to perform a diagnosis by displaying and controlling an X-ray image on a screen.
[0069] The interface box (200) above provides a communication interface for transmitting images from a plurality of X-ray detectors (400) to a designated diagnostic computer (410).
[0070] Each of the first to third X-ray detectors (432, 434, 436) is equipped with the first to third X-ray detectors (132, 134, 136).
[0071] The first to third X-ray detectors (132, 134, 136) are mounted on the first to third X-ray detectors (432, 434, 436) and output an electrical signal according to the intensity of the X-ray for each semiconductor device.
[0072] Each of the first to third connectors (452, 454, 456) is composed of a detector connector and a detector connector formed respectively on the first to third X-ray detectors (432, 434, 436) and the first to third X-ray detectors (132, 134, 136) so that the first to third X-ray detectors (132, 134, 136) can be detachably mounted on the first to third X-ray detectors (432, 434, 436) for X-ray imaging.
[0073] The X-ray generator (460) generates X-rays. The generated X-rays pass through the patient's body and the mattress (120) to reach the X-ray detectors (132, 134, 136).
[0074] Although not shown in the drawing, the skeletal member (110) includes an electrocardiogram device integrally, so that when moving the patient for X-ray imaging, only the patient bed of the present invention can be moved to check the patient's condition.
[0075] As described above, according to one embodiment of the present invention, by arranging a plurality of X-ray detectors in a planar manner under an air mattress or a mattress containing springs made of plastic, it is possible to partially image a patient's body or perform maintenance more easily.
[0076]
[0077] FIG. 6 is an exploded perspective view illustrating an X-ray detector integrated patient bed according to another embodiment of the present invention.
[0078] Referring to FIG. 6, an X-ray detector integrated patient bed (200) according to another embodiment of the present invention includes a skeletal member (210), a mattress (120), an X-ray detector (230), and a shielding part (140). Since the mattress (120) and the shielding part (140) shown in FIG. 6 are identical to the mattress (120) and the shielding part (140) shown in FIG. 1, the same reference numerals are used and a detailed description is omitted.
[0079] The above-mentioned skeletal member (210) defines a frame forming a bed, comprising a frame-shaped bed frame (212) and a plurality of legs (214). Here, the bed frame (212) has a size corresponding to the specifications of the mattress (120). The bed frame (212) includes a lower panel (212a), an upper panel (212b), and a side panel (212c) connecting the lower panel (212a) and the upper panel (212b).
[0080] Specifically, the legs (214) are attached to the lower panel (212a).
[0081] The upper panel (212b) is composed of a main bar having a circular or square cross section having a length that encompasses at least the edge of the mattress (120), and an auxiliary bar attached across the main bar to support the mattress (120). That is, the main bars placed at the edge of the mattress (120) can be formed into a frame shape (or frame shape) by welding or bolting the corner ends together.
[0082] The side panel (212c) is connected to four sides of each of the lower panel (212a) and the upper panel (212b) to form a certain space between the lower panel (212a) and the upper panel (212b). Here, an X-ray detector is accommodated in the space formed between the lower panel (212a) and the upper panel (212b). To this end, the side panel (212c) positioned corresponding to three sides connecting the lower panel (212a) and the upper panel (212b) is configured to be completely sealed, and an insertion hole (212c1) is formed in the side panel (212c) positioned corresponding to one side to accommodate an X-ray detector. The length of the insertion hole (212c1) may be the same as the length of the X-ray detector (230).
[0083] Since the above-mentioned bridge (114) is identical to the bridge (114) shown in FIG. 1, the same reference numeral is used and a detailed description is omitted.
[0084] The above-mentioned skeletal member (210) is a wooden or resin board attached to the bed frame (212) to support and finish the mattress (120), and may further include a base plate (216) and a headboard (218). One or more base plates (216) are placed on the top of the bed frame (212) to support the mattress (120). The headboard (218) is placed on one side of the bed frame (212) in the longitudinal direction.
[0085] The above skeletal member (210) may further include a finishing plate (not shown) that is positioned on the other side and side of the bed frame (212) and wraps around a portion of the mattress (120).
[0086] The X-ray detector (230) is placed under the mattress (120) and detects X-rays passing sequentially through the patient lying on the mattress (120) and the mattress (120) to acquire an image.
[0087] In the above embodiments, an X-ray detecting unit is positioned between the upper panel and the lower panel of a bed frame supporting a mattress, and X-rays reach the X-ray detecting unit via the mattress and the upper panel.
[0088]
[0089] Meanwhile, as another embodiment of the present invention, an X-ray detecting unit may be positioned between a bed frame supporting the mattress and the mattress, that is, under the mattress so as to be in direct contact with the mattress, so that the X-ray reaches the X-ray detecting unit by passing only through the mattress.
[0090] At this time, another embodiment of the present invention is identical to the embodiment of the present invention and the other embodiment of the present invention except for the configuration of the upper panel (112b, 212b), so further detailed description is omitted.
[0091] Similar to what is shown in FIG. 1, the X-ray detecting unit may consist of three X-ray detectors and be placed between the bed frame and the mattress. When only two of the three X-ray detectors are used, an air mattress may be placed in the area where the X-ray detectors are not placed. Accordingly, a flat mattress can be provided to the patient without sagging.
[0092] Also, similar to what is shown in Fig. 6, the X-ray detecting unit may consist of one X-ray detector and be placed between the bed frame and the mattress.
[0093] As described above, according to the present invention, an X-ray detector is integrally combined with a patient bed, thereby eliminating the need to move the patient during imaging examinations of critically ill patients, making it easier to take radiation images for emergency patients or patients with limited mobility.
[0094] Although the invention has been described above with reference to embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as described in the following claims.
