Description

Technology Field

[0001] The present invention is a portable X-ray detector stand that can improve the accuracy of true lateral view X-ray imaging of a patient's knee without additional assistance from an examiner by simultaneously mounting the detector and the leg of a patient lying on a bed while being carried on a portable X-ray imaging device. Background Technology

[0002] For patients who have undergone knee joint surgery, such as knee joint replacement, artificial joint replacement, or ligament reconstruction, it is very important to accurately assess the condition of the knee after surgery.

[0003] To this end, X-ray imaging is an essential examination method for monitoring the progress of the surgery, allowing for the verification of the fusion status of the surgical site, the position of the artificial joint, and the presence of complications such as inflammation or infection.

[0004] However, since the patient has not fully woken up from anesthesia immediately after surgery, it is true that it is not easy to fully extend the patient's knee and place it against the detector in a lateral direction to take an X-ray of the true lateral side of the patient's knee.

[0005] Due to this, there is a problem in obtaining accurate images to determine the precise position of the patient's artificial joint or the status of bone fusion.

[0006] To solve this problem, the examiner must directly hold the patient's knee as shown in FIG. 1, fix it to the detector (10), and look at the monitor (not shown) while simultaneously operating the detector (10) and shooter (20) of the X-ray imaging equipment.

[0007] This series of imaging processes reduces the examiner's ease of X-ray imaging and lowers concentration on operating the imaging equipment, posing a problem that makes it difficult to improve the accuracy of true lateral views of the patient's knee.

[0008] In addition, during the imaging process as illustrated in Fig. 1, if the position of the patient's knee changes slightly, multiple re-imaging sessions are required to obtain a true lateral image, which raises concerns about radiation exposure for both the patient and the examiner due to the re-imaging. Prior art literature

[0010] Republic of Korea Registration No. 10-1930850 The problem to be solved

[0011] The objective of the present invention is to provide a portable X-ray detector stand that can stably support both the detector and the patient's knee simultaneously, thereby freeing the examiner's hand movements and improving the examiner's convenience in X-ray imaging and the accuracy of the true lateral examination of the knee.

[0012] Another objective of the present invention is to provide a portable X-ray detector stand that can minimize concerns regarding radiation exposure for both the examiner and the patient by increasing the accuracy of true-lateral X-ray imaging of a patient's knee and minimizing the need for X-ray re-imaging.

[0013] Another objective of the present invention is to provide a portable X-ray detector stand that can be used even in bed, with a compact size to enhance convenience for transport and portability. means of solving the problem

[0014] To achieve the objective of the present invention, the present invention provides a portable X-ray imaging detector stand comprising: a base plate; a support pad provided on the base plate and formed to allow a patient's leg to be placed thereon; a fixing band formed to fix the patient's leg to the support pad; and a holder formed on one side of the base plate and formed to allow an X-ray imaging device detector to be mounted upright.

[0015] At this time, the fixing band may be made of an elastic material connected between the holder and the support pad.

[0016] At this time, Velcro may be formed between the fixed band and the support pad.

[0017] Additionally, the holder may be composed of a first side wall in contact with the support pad and a second side wall spaced apart from the first side wall to form a slot corresponding to the thickness of the detector.

[0018] At this time, among the first sidewall and the second sidewall, at least the first sidewall may be formed of a radiation-transmitting material.

[0019] In addition, the second side wall may further form a buffer pad on the inner surface facing the detector.

[0020] Additionally, it may further include a support plate that prevents the base from tilting toward the opposite side of the support pad while extending the length of the base toward the opposite side of the support pad relative to the holder.

[0021] At this time, the base plate may be formed with a sliding groove on its upper surface that extends to the outside of the base plate through the bottom of the holder, and the support plate may be formed to extend the length of the base plate by sliding toward the outside of the base plate in the sliding groove.

[0022] At this time, the support plate further includes a stopper protruding upward from the sliding groove, and the support plate forms a guide hole in which the stopper is placed, and when the support plate slides, the end of the guide hole interferes with the stopper, thereby limiting the movement distance of the support plate.

[0023] Additionally, the support pad may include a weight, a cushion provided on the upper part of the weight, and a cover covering the weight and the cushion.

[0024] At this time, the above cover may be formed of artificial leather or natural leather. Effects of the invention

[0025] The effects of the present invention obtained through the above-described solution are as follows.

[0026] First, the present invention allows the detector and the patient's leg to be stably mounted simultaneously, thereby freeing the examiner's hand movements and increasing the examiner's convenience in X-ray imaging. This enables the examiner to focus more on operating the X-ray imaging equipment, which has the effect of increasing the accuracy of the true lateral examination of the patient's knee.

[0027] Second, the present invention has the effect of minimizing the risk of radiation exposure to both the examiner and the patient by increasing the accuracy of X-ray imaging for the true lateral view of a patient's knee, thereby eliminating the need for re-imaging to obtain accurate examination results.

[0028] Furthermore, the present invention can significantly contribute to enhancing safety in medical settings.

[0029] Third, due to its compact size, the present invention has the effect of being easily carried and moved on portable X-ray imaging equipment.

[0030] Accordingly, the present invention can increase usability in various environments and has the effect of improving the work flexibility of medical staff.

[0031] Fourth, since the present invention can stably fix the patient's foot using a fixing band, it has the effect of stably capturing the true side of the knee even when an unconscious patient is lying in bed.

[0032] Fifth, the present invention has the effect of stably mounting the detector by configuring a support plate capable of supporting the detector from one side, thereby preventing the detector from tipping to one side.

[0033] In addition, the present invention forms the support plate with a sliding structure, thereby reducing the overall volume of the stand when not in use, which has the effect of increasing transportation and storage space efficiency. Brief explanation of the drawing

Specific details for implementing the invention

[0035] Hereinafter, a portable X-ray detector stand will be described in more detail with reference to the drawings.

[0036] In describing the embodiments disclosed in this specification, if it is determined that a detailed description of related prior art could obscure the essence of the embodiments disclosed in this specification, such detailed description is omitted.

[0037] The attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that all modifications, equivalents, and substitutions included within the concept and technical scope of the present invention are included.

[0038] In the following description, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0039] In this application, terms such as “comprising” or “having” are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0040] Hereinafter, a portable X-ray imaging detector stand (hereinafter referred to as the "detector stand") according to a preferred embodiment of the present invention will be described with reference to the attached FIGS. 1 to 5.

[0041] The detector stand allows the detector and the patient's knee to be mounted simultaneously for true lateral X-ray imaging of the patient's knee, thereby freeing the examiner's hands during X-ray imaging.

[0042] Accordingly, the present invention allows the examiner to focus more on operating the X-ray imaging equipment, thereby increasing the examiner's convenience in X-ray imaging operations and the accuracy of the true side view examination.

[0043] In addition, the present invention provides a structure that can fix the patient's knee and place it in close contact with a detector while the patient, who has not fully recovered after joint surgery, is lying on a bed. As a result, the present invention can complete a true lateral view in a single shot, thereby reducing the risk of radiation exposure associated with re-shooting.

[0044] In particular, this method can reduce the burden on patients and create a safe imaging environment by preventing situations where patients have to take multiple shots in uncomfortable positions.

[0045] As shown in FIG. 2, the detector stand may include a base plate (100), a support pad (200), a fixing band (300), a holder (400), and a support plate (500).

[0046] The base plate (100) forms the lower part of the detector stand and is formed to be supported on the bed on which the patient is lying.

[0047] The base plate (100) can be made of a square plate for stable support.

[0048] At this time, the base plate (100) may be rectangular in shape, and the length of the base plate (100) is not limited. However, for the compact size of the detector stand, the length of the base plate (100) should be sufficient to accommodate the diameter of an adult male's leg.

[0049] Meanwhile, the base plate (100) can form a sliding groove (110) as shown in FIGS. 2 to 3b.

[0050] The sliding groove (110) forms a sliding space of the support plate (500) described later, and may be a groove that is opened from one side of the base plate (100) toward the outside of the base plate (100).

[0051] Specifically, the sliding groove (110) is formed from the middle point of the base plate (100) to the end of the base plate (100), and the end of the sliding groove (110) can be opened.

[0052] At this time, a stopper (120) may be formed in the sliding groove (110).

[0053] The stopper (120) can restrict excessive movement of the support plate (500) when the support plate (500) moves in a straight line through sliding.

[0054] The stopper (120) can be positioned considering the travel distance of the support plate (500) and can be formed at an intermediate point of the sliding groove (110) as shown in FIG. 2.

[0055] In this way, the distance between the stopper (120) and the point where the sliding groove (110) starts can be the travel distance of the support plate (500).

[0056] Next, the support pad (200) is configured to support the patient's leg and can be placed on the base plate (100).

[0057] The support pad (200) may be formed in a rectangular shape corresponding to the base plate (100) and may include a cushion so that the patient can comfortably rest their leg on it.

[0058] Specifically, the support pad (200) may include a weight (210), a cushion (220), and a cover (230), as shown in FIG. 2.

[0059] The heavy object (210) is configured to prevent the base plate (100) from tipping over toward the detector (10) due to the weight of the detector (10) when the detector (10) is mounted on the holder (400) described later.

[0060] The heavy object (210) constitutes the lower part of the support pad (200), and it may be configured to have a weight that prevents the base plate (100) from tipping over due to the detector (10).

[0061] At this time, the weight (210) may be formed in a rectangular shape corresponding to the base plate (100), and the height of the weight may form the total height of the support pad (200) together with the height of the cushion (220).

[0062] At this time, the height ratio of the weight (210) and the cushion (220) is not limited and can be formed in various ratios.

[0063] For convenience of explanation, the height of the weight (210) in this specification is shown to be greater than the height of the cushion (220).

[0064] The cushion (220) is formed on the weight (210) to allow the patient's foot to be placed comfortably on the support pad (200).

[0065] The cushion (220) may be made of a soft material and may be in a shape corresponding to the shape of the heavy object (210).

[0066] The cover (230) serves to wrap around and protect the heavy object (210) and the cushion (220), and may be made of a material that provides a smooth surface.

[0067] That is, the cover (230) may be made of a leather material that can be wiped clean or disinfected, and it is preferable that it be made of durable natural leather.

[0068] A support pad (200) configured in this way can be placed on a base plate (100) and used as shown in FIG. 4.

[0069] Next, the fixing band (300) serves to fix the patient's leg placed on the support pad (200).

[0070] The fixing band (300) is configured to prevent the patient's leg from moving on the support pad (200) in order to accurately photograph the true side of the patient's knee.

[0071] In particular, since patients who have not fully recovered from knee joint surgery have difficulty controlling knee movement on their own, using a fixing band (300) to fix the patient's leg onto the support pad (200) can help to accurately obtain an X-ray image of the patient's knee.

[0072] At this time, the fixing band (300) may be made of a material having elasticity, and one end of the fixing band (300) may be fixed to one side of the support pad (200) described later.

[0073] Meanwhile, a Velcro (310) may be provided as a means to secure the other end of the fixing band (300) to the support pad (200).

[0074] As shown in FIG. 2, Velcro (310) is formed on the cover (230) of the support pad (200) and on the other end of the fixing band (300), respectively, so that the other end of the fixing band (300) can be easily attached to and detached from the support pad (200).

[0075] As a means of attaching and detaching the fixing band (300) to the support pad (200), Velcro (310) must not necessarily be provided, and a configuration equivalent to Velcro (310) may be provided.

[0076] Next, the holder (400) is configured to mount the detector (10) and is formed on one side of the base plate (100) as shown in FIG. 2.

[0077] As shown in FIGS. 4 and 5, the holder (400) is configured to stand a square-shaped detector (10) upright and can form a slot into which the detector (10) can be inserted.

[0078] Specifically, the holder (400) is composed of two side walls spaced apart from each other, and may consist of a first side wall (410) that contacts the side of the support pad (200) and a second side wall (420) that is spaced apart from the first side wall (410) and forms a slot.

[0079] The first side wall (410) has a width corresponding to the width of the base plate (100), and the height of the first side wall (410) corresponds to the height of the support pad (200).

[0080] At this time, among the bottom surfaces of the first side wall (410) and the second side wall (420), the section corresponding to the width of the sliding groove (110) may be formed in the shape of a groove facing the opposite side of the sliding groove (110) so as not to cause interference when the support plate (500) slides.

[0081] Additionally, the upper part of the first side wall (410) may further form a band connection hole (411) that penetrates both sides.

[0082] The band connection hole (411) is configured to allow one end of a fixing band (300) fixed to one side of the support pad to pass through, and after passing through the band connection hole (411), the one end of the fixing band (300) is attached to the Velcro (310) of the support pad (200). It can be requested.

[0083] The second side wall (420) is spaced apart from the first side wall (410) and forms a slot with the first side wall (410), and the slot may correspond to the thickness of the detector (10).

[0084] At this time, the second side wall (420) may further form a cushioning pad (421) on the inner side.

[0085] The cushioning pad (421) is configured to prevent damage to the detector (10) by preventing friction with the second side wall (420) when the detector (10) is inserted into the slot between the first side wall (410) and the second side wall (420) and mounted.

[0086] The material of the cushioning pad (421) is not limited and must be capable of preventing damage caused by friction with the detector (10).

[0087] At this time, multiple cushioning pads (421) may be provided in the height direction of the second side wall (420).

[0088] Meanwhile, among the first side wall (410) and the second side wall (420), at least the first side wall (410) may be made of a material with high radiation transparency.

[0089] The first side wall (410) faces the X-ray camera and blocks part of the light-receiving surface of the detector (10), which can affect the amount of radiation transmitted from the X-ray camera and degrade the image quality.

[0090] Therefore, in order to obtain accurate knee true side data, the material of the first side wall (410) must be selected to have high radiotransparency.

[0091] At this time, acrylic with excellent radiation transparency can be used as the material of the first side wall (410).

[0092] Of course, it is possible to make both the first side wall (410) and the second side wall (420) out of a material with high radiation transparency, but the holder (400) requires a certain level of rigidity to stably mount the detector (10).

[0093] To this end, it is preferable to select a material other than acrylic for the second side wall (420) that can maintain rigidity, such as metal, rather than using acrylic material.

[0094] That is, it is important to manufacture at least the first side wall (410) among the first side wall (410) and the second side wall (420) with a material that is highly radiotransmissive, so that the X-ray imaging quality can be improved while maintaining the function of the holder (400).

[0095] Next, the support plate (500) serves to prevent the base plate (100) from tipping toward the holder (400) due to the weight of the detector (10) when the detector (10) is inserted into the holder (400) and mounted.

[0096] Looking at the structure of the detector stand of the present invention, the patient's leg is placed on the support pad (200) with respect to the holder (400), and the detector (10) is mounted on the holder (400).

[0097] In this structure, the weight of the patient's leg and the detector (10) are balanced, so the center of gravity of the detector stand is maintained, and thus, tipping does not occur.

[0098] However, a problem may occur when only the detector (10) is mounted on the holder (400) before the patient's leg is placed on the support pad (200).

[0099] In other words, this is because there is a risk that the base plate (100) will tilt to the opposite side of the support pad (200) and tip over due to the weight of the detector (10).

[0100] To prevent this, the support plate (500) extends the length of the base plate (100) to the opposite side of the support pad (200), thereby preventing the base plate (100) from tipping over.

[0101] By doing this, the stability of the detector stand is further ensured, and the situation in which the base plate (100) tip over due to the weight of the detector (10) can be prevented even before the patient's leg is placed on the support pad (200).

[0102] The support plate (500) is formed to be slidable in the sliding groove (110) of the base plate (100) and has a size corresponding to the size of the sliding groove (110).

[0103] At this time, the support plate (500) forms a guide hole (510).

[0104] The guide hole (510) corresponds to the position of the stopper (120), and the support plate (500) can prevent excessive movement by interfering with the end of the guide hole (510) on the stopper (120).

[0105] That is, as can be seen through FIGS. 3a and 3b, the support plate (500) moves from the sliding groove (110) to the opposite side (right side in the drawing) of the support pad (200) to extend the length of the base plate (100) and maintain stable support of the detector stand. In this process, the end of the guide hole (510) is caught on the stopper (120), preventing excessive movement of the support plate (500) and thus preventing the support plate (500) from detaching from the base plate (100).

[0106] Below, we will examine the process of photographing the true lateral side of a patient's knee using a detector stand configured as described above, with further reference to the attached Fig. 5.

[0107] The examiner moves the imaging equipment and detector stand for the patient's knee X-ray to the patient's room.

[0108] At this time, the compact detector stand can be stored in one of the spaces of the portable X-ray imaging equipment and transported.

[0109] For example, when a patient is lying in bed in an unconscious state after knee joint surgery and has not fully recovered, the examiner places the patient's leg on a support pad (200) on a base plate (100). At this time, specifically, the patient's calf area is placed on the support pad (200).

[0110] Afterward, the inspector inserts the detector (10) into the slot of the holder (400) and mounts it upright.

[0111] At this time, the light-receiving surface of the detector (10) is directed toward the patient's knee and the X-ray machine, so the patient's knee is placed between the detector (10) and the X-ray machine.

[0112] Afterward, the examiner moves the leg of the unconscious patient lying on the bed to bring the knee into contact with the light-receiving surface of the detector (10), and then uses a fixing band (300) to fix the patient's leg onto the support pad (200).

[0113] At this time, the examiner passes the fixing band (300) through the band connection hole (411) and pulls it to attach it to the Velcro (310) on the side of the support pad (200), thereby stably fixing the patient's knee in close contact with the light receiving surface of the detector (10).

[0114] Once preparations for X-raying the true side of the patient's knee are complete, the examiner's hands are free.

[0115] Afterward, the examiner directly operates the X-ray imaging equipment and emits X-rays through the knee to the light-receiving surface of the detector (10).

[0116] During this process, the side of the patient's knee is positioned accurately between the detector (10) and the X-ray machine without additional assistance from the examiner.

[0117] Therefore, the examiner can focus solely on operating the X-ray equipment, enabling more accurate imaging of the true lateral aspect of the patient's knee.

[0118] Through this process, the examiner can perform efficient and accurate true lateral knee radiography, while simultaneously ensuring patient safety and convenience.

[0119] As explained above, the portable X-ray detector stand of the present invention has a structure capable of simultaneously supporting the subject's legs and the detector.

[0120] Thanks to this structure, the present invention enables the patient's knee to be accurately aligned with the detector without additional assistance from the examiner.

[0121] In particular, when imaging the true lateral view of the knee of an unconscious patient who has undergone surgery, utilizing the detector stand of the present invention can significantly improve the convenience of the examiner and allow the patient to undergo imaging in a more stable state, thereby creating a safe imaging environment.

[0122] Accordingly, the present invention can improve the accuracy of true-lateral X-ray imaging of a patient's knee, and since improved imaging accuracy minimizes the need for re-imaging, it can reduce the risk of unnecessary radiation exposure for both the examiner and the patient.
