Description

Technical Field

[0001] This utility model relates to the field of radiation protection, and in particular to a radiation protection cabin. Background Technology

[0002] DSA (Digital Subtraction Angiography) is a technique that digitally processes angiography images, removing unwanted tissue images and retaining only vascular images. It is suitable for the examination and treatment of systemic vascular diseases and tumors. The radiation source for the equipment during normal operation comes from X-rays emitted by the X-ray tube source assembly. During interventional procedures, staff operate under X-ray fluoroscopy, standing less than 0.5 meters from the patient's irradiation area. Therefore, radiation workers need auxiliary protective equipment such as protective curtains and bedside curtains, and must wear protective gear such as lead aprons and goggles. Because the operator must first wear a short-sleeved surgical gown, then a lead apron, and finally a sterile surgical gown, the lead apron is quite thick and heavy.

[0003] Lead aprons, due to their weight, restrict the wearer's mobility and pose certain health risks. Furthermore, lead aprons offer insufficient effective radiation protection, leaving the head, face, limbs, and especially the arms exposed to ionizing radiation. The damage caused by radiation to the body increases with the dose of radiation. High doses of radiation can cause tissue damage and lead to cancer. Even low doses, especially prolonged exposure to low doses, can induce cancer in irradiated organs and tissues, and cause genetic defects in irradiated germ cells. Cardiologists are at high risk of developing thyroid, lung, gastrointestinal, and hematologic malignancies; radiation-induced cataracts and retinopathy are also common; and lumbar disc herniation is frequently observed.

[0004] In addition, during special surgeries, doctors need to stand at the X-ray tube, where there is a lack of lead plates or bedside protective curtains. Or, when the patient's condition changes and the nurse needs to administer medication, the nurse needs to operate from the left side of the DSA X-ray tube. Although protective equipment is worn, there is a lack of auxiliary protective facilities, and some areas of the body are not protected, resulting in an increase in the overall radiation dose.

[0005] CN201410510036.4 discloses a movable radiation protection chamber, which includes a front fixed lead glass and a left fixed lead glass with an operating port. Below these are metal lead plates, including a vertical metal lead plate and an inclined metal lead plate. A base frame and casters are connected to the metal lead plates. The front fixed lead glass has an outer fixed lead glass and an inner sliding lead glass. The lower part of the outer fixed lead glass has a large round hole and a right-hand operating port, while the inner sliding lead glass has a small round hole corresponding to the outer fixed lead glass. The front and left fixed lead glass are inclined outwards at an angle of 10° to 20° with respect to the vertical direction. The inclined metal lead plate is directly connected to the base frame and is inclined inwards at an angle of 40° to 50° with respect to the base frame. Using this movable radiation protection chamber, surgeons can be freed from heavy lead aprons during surgery, eliminating the need for heavy-duty work, reducing fatigue damage without affecting surgical operations, and minimizing radiation harm to the surgeon.

[0006] The device structure used in the prior art has low structural flexibility and is difficult to adapt to reasonable height requirements. Furthermore, the enclosure surface of the prior art is only bidirectional, failing to address the issue of insufficient protection for certain body parts of staff during special surgical procedures. Moreover, conventional adjustable vertical protective panels often use a unidirectional pressure bar structure to unfold the panel. This means that when the entire panel is subjected to compressive forces from other directions, the unidirectional pressure bar often cannot achieve a locking structure similar to a jack. Using a jack, however, requires not only an explosion-proof overall structure but also rapid vertical adjustment, which is often difficult to achieve with a jack.

[0007] Based on the above problems, a radiation protection chamber is needed to solve them. Summary of the Invention

[0008] This invention addresses the problems of lead aprons, which are heavy and restrict the wearer's mobility, posing health risks. Furthermore, lead aprons offer insufficient radiation protection, leaving the head, face, limbs, and especially the arms exposed and vulnerable to ionizing radiation. The invention provides a radiation protection cabin with an adjustable semi-enclosed structure that solves these problems.

[0009] This utility model provides a radiation protection chamber, including a first protective panel, a second protective panel, a moving device, and a lifting mechanism. The first protective panel is a plate consisting of a single piece of lead glass and several lead screens connected vertically. The lead screens are installed under the lead glass using soft bags. The second protective panel is a vertically arranged lead plate. The transverse cross-sections of both the first and second protective panels are symmetrical structures composed of arcs and several line segments, forming smooth polylines. The first and second protective panels have the same shape and cross-sectional size. The top height of the first protective panel is greater than that of the second protective panel. The lifting mechanism is located between the first and second protective panels. The top surface of the first protective panel has a lifting beam protruding inward from the panel surface. The bottom end of the lifting mechanism connects the top surface of the second protective panel and the bottom surface of the lifting beam of the first protective panel. The lifting mechanism is a triangular lifting rod device with variable angle and length, symmetrically arranged about the symmetry line of the first protective panel as the axis of symmetry. One corner of the lifting mechanism is a fixed right angle. The moving device is located at the bottom of the second protective panel and consists of casters with locking mechanisms.

[0010] In a preferred embodiment of the radiation protection cabin described in this utility model, a horizontally arranged top plate is provided on the top surface of the first protective panel, and the top plate is a radiation protection structure.

[0011] In a preferred embodiment of the radiation protection cabin described in this utility model, the lifting mechanism includes a plurality of inclined lifting rods and a plurality of vertical lifting rods. The number of inclined lifting rods and vertical lifting rods is the same, and the inclined lifting rods and vertical lifting rods are arranged in a one-to-one correspondence to form a stable group. The number of both inclined lifting rods and vertical lifting rods is even. Both the inclined lifting rods and vertical lifting rods are symmetrically arranged with respect to the middle of the first protective panel. One end of each inclined lifting rod is hinged to the bottom surface of the lifting beam of the first protective panel and the top surface of the second protective panel, respectively. The two ends of each vertical lifting rod are fixedly installed on the bottom surface of the lifting beam of the first protective panel and the top surface of the second protective panel, respectively. One hinge point of the inclined lifting rod and the fixed point of the group of vertical lifting rods at the same height are set at the same point.

[0012] In a preferred embodiment of the radiation protection cabin described in this utility model, the inclined lifting rod and the vertical lifting rod are hydraulic rods or pneumatic rods.

[0013] In a preferred embodiment of the radiation protection chamber described in this utility model, the transverse cross-section of the first protective panel and the transverse cross-section of the second protective panel are two line segments circumscribed by a semi-circular arc, with the two endpoints of the semi-circular arc being tangent to the two line segments, and the line segments being of equal length and parallel.

[0014] In a preferred embodiment of the radiation protection cabin described in this utility model, the number of casters on the moving device is odd, and the casters are symmetrically arranged along the center line of the second protective panel.

[0015] In a preferred embodiment of the radiation protection cabin described in this utility model, the mounting points at both ends of the inclined lifting rod and the mounting points at both ends of the vertical lifting rod are both located at corresponding positions on the two line segments of the first and second protective panels.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) The height of this device is adjustable, which provides greater flexibility compared to existing products;

[0018] (2) This device adopts a triangular support mode for jacking, which is different from the existing unidirectional jacking. Conventional jacking rods are prone to relative displacement when subjected to non-vertical forces. The triangular structure effectively avoids the influence of non-vertical forces, making the protective cabin more stable and less susceptible to interference during operation.

[0019] (3) This device adopts an overlapping structure, which effectively enhances the radiation resistance of the middle part and is beneficial to the protection of internal organs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] like Figure 1As shown, a radiation protection chamber includes a first protective panel 1, a second protective panel 2, a moving device 3, and a lifting mechanism 4. The first protective panel 1 is a single piece of lead glass and several lead screens connected vertically. The lead screens are installed under the lead glass using soft bags. The second protective panel 2 is a vertically arranged lead plate. The transverse cross-sections of both the first and second protective panels are symmetrical structures composed of arcs and several line segments, forming smooth polylines. The first and second protective panels 1 and 2 have the same shape and cross-sectional size. The top height of the first protective panel 1 is greater than the top height of the second protective panel 2. The second protective panel 2 is provided with an operating port. The protective panel 1 has a vertical strip opening at the vertical position corresponding to the operating port. The width of the strip opening is greater than or equal to the width of the operating port. The lifting mechanism 4 is located between the first protective panel 1 and the second protective panel 2. The top surface of the first protective panel 1 has a lifting beam that protrudes inward from the panel surface. The bottom end of the lifting mechanism 4 is connected to the top surface of the second protective panel 2 and the bottom surface of the lifting beam of the first protective panel 1. The lifting mechanism 4 is a triangular lifting rod device with variable angle and length that is symmetrically arranged with the symmetry line of the first protective panel 1 as the axis of symmetry. One corner of the lifting mechanism 4 is a fixed right angle. The moving device 3 is located at the bottom of the second protective panel 2. The moving device 3 is a universal wheel with a locking mechanism.

[0028] The lead screen is placed inside a fabric bag, and the upper opening of the fabric bag is secured to the lower edge of the lead glass with fasteners to achieve closure.

[0029] like Figure 2 As shown, the lifting mechanism 4 includes a pair of inclined lifting rods 41 and a pair of vertical lifting rods 42. Both the inclined lifting rods 41 and the vertical lifting rods 42 are symmetrically arranged with respect to the middle of the first protective panel 1. One end of each inclined lifting rod 41 is hinged to the bottom surface of the lifting beam of the first protective panel 1 and the top surface of the second protective panel 2, respectively. Both ends of the vertical lifting rods 42 are fixedly installed on the bottom surface of the lifting beam of the first protective panel 1 and the top surface of the second protective panel 2, respectively. One hinge point of the inclined lifting rod 41 and a fixed point at the same height of the group of vertical lifting rods 42 are located at the same point. (See attached diagram) Figure 2 Distinguished from the appendix Figure 1 A bottom hinge option is available, but both top and bottom hinges are acceptable in practical applications. Under normal circumstances, the bottom hinge is preferred for a wider field of vision.

[0030] like Figure 3 As shown, in this embodiment, the transverse cross-section of the first protective panel 1 and the transverse cross-section of the second protective panel 2 are two line segments circumscribed by a semicircular arc. The two endpoints of the semicircular arc are tangent to the two line segments, and the line segments are of equal length and parallel.

[0031] Optionally, the inclined lifting rod 41 and the vertical lifting rod 42 are hydraulic rods or pneumatic rods.

[0032] Optionally, the top surface of the first protective panel 1 is provided with a horizontally arranged top plate, which is a radiation protection structure.

[0033] In this embodiment, there are three outward-facing wheels, and the casters are symmetrically arranged along the center line of the second protective panel 2. An odd number of casters is used because, since this device is made of glass and has a large weight, any asymmetrical structure or non-vertical support method could cause the entire structure to tip over in one direction. Therefore, a symmetrical even number of wheels is used.

[0034] When using this device, the surface of the device needs to be covered with a sterile sleeve or sterile towel. The specific structure and height of the sterile sleeve used during use are adjusted according to the actual outer surface structure of the device after production, so as to achieve the effect of wrapping and sealing the outer surface of the device by using the sterile sleeve and sterile towel together, so as to meet the aseptic operation principle of the operating room.

[0035] Example 2

[0036] Based on Embodiment 1, in order to achieve the effect of not obstructing, in this embodiment, the mounting points at both ends of the inclined lifting rod 41 and the mounting points at both ends of the vertical lifting rod 42 are set at the corresponding positions of the two line segments of the first protective panel 1 and the second protective panel 2.

[0037] Example 3

[0038] Unlike Embodiment 1, in this embodiment, the transverse cross-section of the first protective panel 1 and the transverse cross-section of the second protective panel 2 are composed of four lines and connecting arcs, wherein the middle two lines are at an angle of 40 to 50 degrees, and the remaining two lines are set at the free ends of the two lines at the angle, and are transitioned to be parallel to each other by the arc.

[0039] Example 4

[0040] The optional second protective panel adopts a vertical two-section structure, which makes the distance between the ground and the operating port adjustable. The vertical adjustment of the two-section structure can be achieved by using the same solution as the adjustment mechanism in this technical solution or by using a structure that lifts the entire structure vertically.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
