Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, and more specifically to a follow-up protective lead skirt for a CT examination bed. Background Technology

[0002] In medical imaging diagnosis, computed tomography (CT) is a widely used examination method. During a CT scan, the patient usually lies flat on the examination table and is moved into or remains within the aperture of the CT scanner to be scanned. Although modern CT equipment has high radiation protection performance, in order to further reduce the scattered radiation dose received by non-target areas, protective lead skirts made of lead or lead-containing materials are often used clinically to locally shield the patient.

[0003] In existing technologies, lead skirts require technicians to repeatedly move them and put them on patients, then remove and store them after examination, which increases workload; some protective lead skirts can only cover the front or sides of the patient, and cannot achieve 360-degree coverage, leaving some key areas (such as the abdomen and pelvis) exposed; moreover, protective lead skirts need to be stored separately, and technicians may forget to use them due to being busy, or they may be lost due to frequent handling.

[0004] In summary, how to solve the problems of repeated moving of protective lead skirts in existing technologies, which increases the workload, exposes some key parts, and may be forgotten to be used, has become an urgent problem to be solved in this field. Therefore, it is necessary to propose a follow-up protective lead skirt for CT examination tables. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a follow-up protective lead skirt for a CT examination bed. Through the adaptation design of the sliding connection mechanism at the bottom of the padding layer with the slide groove of the CT examination bed, the main body of the lead skirt can move synchronously with the examination bed, eliminating the need for medical staff to repeatedly manually move or adjust its position. By folding and locking, it achieves surround protection for the patient's critical parts. The folding and fixing operation of the side-flipping layer is intuitive and simple, reducing the possibility that technicians may miss protective procedures due to cumbersome operation steps.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a follow-up protective lead skirt for a CT examination bed, comprising a lead skirt body, the lead skirt body comprising a padding layer and side-turning layers connected to both sides of the padding layer.

[0007] The bottom of the padding layer is equipped with a sliding connection mechanism, which is used to match the sliding grooves on both sides of the CT examination table, so that the lead skirt body can move along the sliding grooves; a fixing mechanism is also provided between the side-flipping layer and the padding layer, which is used to fix the side-flipping layer after it is flipped up, forming a protective wrap around the patient.

[0008] The technical principles of the above solution are as follows:

[0009] The lead skirt body can move synchronously along the slide grooves on both sides of the CT examination table through the sliding connection mechanism at the bottom of the padding layer, realizing the adjustment function with the examination table. In use, the side flip-up layers on both sides of the padding layer are flipped up towards the patient, and the positioning is completed by the fixing mechanism between the side flip-up layers and the padding layer, so that the side flip-up layers and the padding layer together form a wrapping structure around the patient's key areas. When not in use, the lead skirt body naturally hangs over the edge of the examination table by relying on the sliding connection mechanism, and the whole is fixed by the sliding and flipping of the mechanical structure.

[0010] The above approach has the following beneficial effects:

[0011] 1. This invention utilizes a sliding connection mechanism at the bottom of the padding layer that adapts to the CT examination bed's slide groove. This allows the lead skirt body to move synchronously with the examination bed, eliminating the need for medical staff to repeatedly manually move or adjust its position. This structure simplifies the cumbersome process of manually resetting the protective device after adjusting a traditional lead skirt examination bed. Simultaneously, the adaptability of the sliding connection mechanism ensures the stability of the follow-up process, reduces equipment maintenance costs, and improves the continuity and efficiency of radiology examinations.

[0012] 2. This invention utilizes a fixing mechanism design to achieve comprehensive protection of critical patient areas through folding and locking. In use, the side-flipping layer folds up from both sides of the padding layer and forms a closed protective space through the fixing mechanism, together with the padding layer, constituting a 360° protective structure that covers radiation-sensitive areas such as the abdomen and pelvis. This physical structure reduces blind spots, and the locking state of the side-flipping layer ensures that protection will not fail due to changes in patient position or displacement of the lead skirt during examination, thus improving the reliability of radiation protection.

[0013] 3. When not in use, the lead skirt body of this invention can hang naturally over the edge of the examination table, reducing the risk of loss or damage caused by careless placement of traditional lead skirts. In use, the folding and fixing operation of the side-flipping layer is intuitive and simple, reducing the possibility that technicians may overlook protective procedures due to cumbersome operation steps; in addition, the mechanical locking characteristics of the fixing mechanism ensure the stability of the protective state, indirectly reducing the potential for medical disputes caused by oversights in protective measures.

[0014] Furthermore, the sliding connection mechanism includes slider assemblies symmetrically arranged at the bottom of the padding layer. Each slider assembly includes several slider bodies and sliding groove adapter blocks. The slider bodies are all symmetrically and fixedly connected to the bottom of the padding layer. The slider bodies are all fixedly connected to the sliding groove adapter blocks, and the sliding groove adapter blocks are all slidably engaged with the sliding grooves on both sides of the CT examination table.

[0016] Furthermore, the fixing mechanism consists of a male and a female hook and loop fastener that are detachably connected to each other; the male hook and loop fastener is fixedly connected to the side of the side-turning layer away from the padding part, and the female hook and loop fastener is fixedly connected to the outer wall of the edge of the padding layer.

[0017] Beneficial effects: The hook and loop fasteners allow for detachable connection, enabling quick and easy fastening and secure fixation after the side layer is folded up. The tight fit of the fasteners effectively maintains the protective wrap-around shape of the side layer and padding layer. Disassembly is simple, requiring only a light tear, enhancing ease of use and ensuring consistent protective performance.

[0018] Furthermore, the fixing mechanism consists of a buckle head and a buckle hole that are detachably connected to each other. The buckle head is fixedly connected to the side of the side-turning layer away from the matting part, and the buckle hole is located on the outer wall of the edge of the matting layer.

[0019] Beneficial effects: The snap-on head and snap-on hole are detachably connected. After the side layer is flipped up, the snap-on head can be inserted into the snap-on hole to lock quickly. The connection is strong and not easy to loosen, ensuring the stability of the protective form. Disassembly is simple and efficient, requiring only pressing the snap-on head. The structure is simple and durable, suitable for frequent opening and closing scenarios, ensuring both protective reliability and ease of use.

[0020] Furthermore, each side-tilting layer is equipped with an observation window made of transparent lead glass; the surface of the lead skirt body is marked with radiation protection warning signs; the lead skirt body is made of lead rubber material with a lead equivalent of ≥0.5mmPb; the width of the padding layer is 10-20cm wider than the CT examination table, and the width of the side-tilting layer is 30-50cm.

[0021] Beneficial effects: The transparent lead glass observation window allows for real-time observation of the patient's condition without the need to lift the lead skirt; radiation warning signs enhance safety reminders; the lead rubber material ensures effective radiation shielding; the widened padding layer and side-flipping layer design achieve full coverage of the examination bed and surrounding protection of key areas, improving safety and practicality.

[0022] Furthermore, a detachable connection mechanism is provided between the side-turning layer and the padding layer. This detachable connection mechanism is used to adjust the coverage of the side-turning layer according to the body shape of different patients. Each slider assembly is equipped with a locking device, which is used to lock the slider body after the lead skirt body moves to the target position.

[0023] Beneficial effects: The detachable connection mechanism allows for flexible adjustment of the side-flipping layer coverage to fit different patient body shapes and ensure a proper fit; the locking device locks the slider to prevent displacement, ensuring the lead skirt remains stable in the target position, improving the accuracy of protection and ease of operation, and balancing adaptability and reliability.

[0024] Furthermore, the detachable connection mechanism consists of several bases, pressure strips, and knob screws; the bases are all arranged and fixedly connected to both sides of the edge of the padding layer, the pressure strips are respectively fixedly connected to the side of the side-turning layer away from the fixing mechanism, and the knob screws all pass through the pressure strips and are threaded into the bases.

[0025] Beneficial effects: The multi-base arrangement provides multiple adjustment levels, and the knob screw can be manually tightened without tools. The side-flipping layer coverage can be adjusted by disassembling and installing it on different bases to adapt to different patient body shapes. The threaded locking structure ensures a stable connection, prevents displacement, improves the fit of the protective layer and the ease of operation, and balances adjustment flexibility with fixation reliability.

[0026] Furthermore, the detachable connection mechanism consists of several detachable arc-shaped rings and hooks; the arc-shaped rings are all arranged and fixedly connected to both sides of the padding layer, and the hooks are respectively fixedly connected to the side of the side-turning layer away from the fixing mechanism; each hook is hinged with a baffle, and a torsion spring is sleeved on the outside of the hinge axis of the baffle and the hook.

[0027] Beneficial effects: The multi-position arrangement of the arc-shaped rings adapts to different body shapes. After the hook is attached to the arc-shaped rings, the torsion spring drives the baffle to automatically lock and prevent it from falling off. The side-flipping layer coverage can be manually adjusted without tools. The structure is simple and easy to operate. The connection is stable and not easy to shift, effectively improving the protective fit and adjustment efficiency.

[0028] Furthermore, the detachable connection mechanism consists of several detachable main zippers and secondary zippers; the main zippers are all arranged and fixedly connected to both sides of the edge of the padding layer, and the secondary zippers are all fixedly connected to the side of the side-turning layer away from the fixing mechanism.

[0029] Beneficial effects: The main zipper is arranged on the padding layer, and the secondary zipper corresponds to the side flip layer. The zipper engagement enables quick disassembly and connection. The coverage of the side flip layer can be manually adjusted without tools, and multiple positions can be used to adapt to different patient body shapes. The zipper connection is tight and does not easily shift, making operation convenient and efficient, improving the fit of the protective clothing and the flexibility of use.

[0030] Furthermore, the detachable connection mechanism consists of several permanent magnets and adsorption strips that are magnetically coupled to each other; the permanent magnets are fixedly connected to the bottom of the side-turning layer on the side away from the fixing mechanism, and the adsorption strips are arranged and fixedly connected to both sides of the edge of the padding layer.

[0031] Beneficial effects: Through the magnetic cooperation between the permanent magnet and the adsorption strip, adsorption and separation can be achieved without tools. The adsorption strip has multiple positions to adjust the coverage of the side-flipping layer, adapting to different patient body shapes. The magnetic connection is stable and prevents displacement. The operation is convenient and efficient, improving the fit and adjustment efficiency of the protective layer.

[0032] Furthermore, the locking device consists of a spring and a locking pin; the locking pin slides in conjunction with the slider body, one end of the spring is fixedly connected to the locking pin, and the other end of the spring is fixedly connected to the inner wall of the slider body; the bottom end of the locking pin is a hemispherical structure, which contacts the groove.

[0033] Beneficial effects: The spring-driven locking pin automatically resets, ensuring smooth movement of the lead skirt body; once in position, the spring pushes the locking pin to lock the slide groove, allowing for manual locking without tools, making operation convenient; the simple and reliable structure effectively prevents lead skirt displacement and ensures accurate and stable protection position.

[0034] Furthermore, the locking device consists of an operating wrench and an eccentric cam; the operating wrench is fixedly connected to the outer wall of the eccentric cam, and a rotating shaft is fixedly connected to the outer wall of the slider body; the eccentric cam and the rotating shaft rotate eccentrically in cooperation, and the outer wall of the eccentric cam contacts the slide groove.

[0035] Beneficial effects: The eccentric cam is driven to rotate eccentrically around the shaft by operating the wrench, and the locking and unlocking are achieved by changing the eccentricity. It is convenient to operate manually without tools; the outer wall of the cam is in close contact with the slide groove, and the eccentric structure has strong locking ability, which effectively prevents the lead skirt from shifting, ensures the accurate and stable protective position, and improves operating efficiency.

[0036] Furthermore, the locking device consists of a pre-tightening knob and a screw; the pre-tightening knob and the screw are coaxially fixedly connected, the screw is threaded onto the slider body, and a rubber sleeve is fixedly connected to the bottom end of the screw, with the rubber sleeve in contact with the slide groove.

[0037] Beneficial effects: The drive screw can be manually rotated using the pre-tightening knob, which can be operated without tools, making it convenient and efficient; the threaded fit allows for precise adjustment, and the rubber sleeve increases the friction with the slide, locking it securely and preventing displacement; the simple and reliable structure ensures that the lead skirt is stable in the target position, improving the accuracy of protection and operational efficiency.

[0050] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be described in further detail below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the embodiments.

[0052] Example 1, as shown in the attached document Figure 1 As shown: A follow-up protective lead skirt for a CT examination table includes a lead skirt body, which includes a padding layer 1 and a side-turning layer 2 connected to both sides of the padding layer 1.

[0053] The bottom of the padding layer 1 is provided with a sliding connection mechanism, which is used to match the sliding grooves on both sides of the CT examination table, so that the lead skirt body can move along the sliding grooves; a fixing mechanism is also provided between the side-flipping layer 2 and the padding layer 1, which is used to fix the side-flipping layer 2 after it is flipped up, forming a protective wrap around the patient.

[0054] The sliding connection mechanism includes slider assemblies symmetrically arranged at the bottom of the padding layer 1. The slider assembly includes several slider bodies 3 and sliding groove adapter blocks. The slider bodies 3 are all symmetrically fixed to the bottom of the padding layer 1 with screws 19. The slider bodies 3 are all integrally formed with the sliding groove adapter blocks, and the sliding groove adapter blocks are all slidably engaged with the sliding grooves on both sides of the CT examination table.

[0055] Combination Figure 2 As shown, the fixing mechanism consists of a male hook and loop fastener 4 and a female hook and loop fastener 5 that are detachably connected to each other; the male hook and loop fastener 4 is fixedly sewn to the side of the side-turned layer 2 away from the padding part, and the female hook and loop fastener 5 is fixedly sewn to the outer wall of the edge of the padding layer 1.

[0056] Each side-tilting layer 2 is equipped with an observation window made of transparent lead glass; the surface of the lead skirt body is marked with radiation protection warning signs; the lead skirt body is made of lead rubber material with a lead equivalent of ≥0.5mmPb; the width of the padding layer 1 is 10-20cm wider than the CT examination bed, and the width of the side-tilting layer 2 is 30-50cm.

[0057] The specific implementation process is as follows:

[0058] First, fix the slider body 3 and the slide groove adapter block to the bottom of the padding layer 1, so that the slide groove adapter block slides and engages with the slide grooves on both sides of the CT examination bed to complete the installation. When not in use, the lead skirt body hangs naturally on the side of the bed. Before use, push the lead skirt body along the slide groove to the corresponding position of the patient's examination area; when in use, flip up the two side flipping layers 2 towards the patient, and quickly attach and fix them to the male and female sides of the Velcro on the edge of the side flipping layer 2 and the padding layer 1 to form a protective structure that wraps around the patient's key areas.

[0059] The transparent lead glass observation window allows for real-time monitoring of the patient's condition, facilitating technicians to observe the patient's breathing and posture without needing to open it. Radiation protection warning signs reinforce safety reminders. The lead rubber skirt body, combined with the widened padding layer 1 and side-flipping layer 2, achieves full coverage of the examination bed and radiation shielding of key areas. After use, the side-flipping layer 2 can be easily separated by gently tearing the Velcro, and the lead skirt body will naturally fall back to its original position. The entire process requires no tools and integrates follow-up, protection, and storage.

[0060] Example 2, as shown in the attached document Figure 3 As shown, the difference from the above embodiments is that in some embodiments, the fixing mechanism is fixed by Velcro, which may result in insufficient fixing force. The fixing mechanism in this embodiment is a buckle head 6 and a buckle hole that are detachably connected to each other. The buckle head 6 is fixedly connected to the side of the side flipping layer 2 away from the padding part, and the buckle hole is set on the outer wall of the edge of the padding layer 1.

[0061] The specific implementation process is as follows: A detachable connection is used between the buckle head 6 and the buckle hole. After the side-flipping layer 2 is flipped up, the buckle head 6 can be quickly locked by inserting it into the buckle hole. The connection strength is high and it is not easy to loosen, ensuring the stability of the protective form. Disassembly is achieved by pressing the buckle head 6, making the operation convenient and efficient. The structure is simple and durable, suitable for frequent opening and closing scenarios, ensuring both protective reliability and ease of use.

[0062] Example 3 differs from the above examples in that a detachable connection mechanism is provided between the side-turning layer 2 and the padding layer 1. The detachable connection mechanism is used to adjust the coverage of the side-turning layer 2 according to the body shape of different patients. The slider assembly is equipped with a locking device, which is used to lock the slider body 3 after the lead skirt body moves to the target position.

[0063] Combination Figure 4 As shown, the detachable connection mechanism consists of several bases 7, pressure strips 20, and knob screws 21; the bases 7 are all arranged and fixedly bonded to both sides of the edge of the padding layer 1, the pressure strips 20 are respectively fixedly bonded to the side of the side-turning layer 2 away from the fixing mechanism, and the knob screws 21 all pass through the pressure strips 20 and are threadedly engaged with the bases 7.

[0064] Combination Figure 8 As shown, the locking device consists of a spring 14 and a locking pin 15; the locking pin 15 is slidably engaged with the slider body 3, one end of the spring 14 is fixedly bonded to the locking pin 15, and the other end of the spring 14 is fixedly bonded to the inner wall of the slider body 3; the bottom end of the locking pin 15 is a hemispherical structure, and the hemispherical structure contacts the groove.

[0065] The specific implementation process is as follows: By manually rotating the knob screw 21 on the pressure strip 20 of the side-flipping layer 2, the threaded engagement between it and the base 7 on both sides of the padding layer 1 is loosened. After the side-flipping layer 2 is slid laterally to the target coverage area, the knob screw 21 is tightened in the opposite direction to complete the locking, adapting to the patient's body shape. When pushing the lead skirt body, the locking pin 15 is pulled to disengage it from the slide groove, allowing the slider body 3 to slide smoothly. After moving to the target position, the spring 14 returns to its original position and pushes the locking pin 15 to lock the slide groove, completing the locking.

[0066] During protection, the folded side-flipping layer 2 is attached to the padding layer 1 through the fixing mechanism to form a surrounding protection. After use, the fixing mechanism is released to allow the side-flipping layer 2 to hang down. When the coverage area needs to be adjusted, the knob screw 21 is loosened again. When moving the lead skirt body, the locking pin 15 is used to compress the spring 14 to release the lock and push it to reset. The mechanical linkage of coverage area adjustment, follow-up movement, position locking and state switching is completed by manually turning, pushing and pressing. The adjustment operation can be achieved without the assistance of tools.

[0067] Example 4, as shown in the appendix Figure 5 As shown, the difference from the above embodiments is that in some embodiments, the detachable connection mechanism adopts a threaded connection, which may make the installation operation of the side-flipping layer 2 more complicated and thus increase the operation time. The detachable connection mechanism of this embodiment is a number of detachable arc-shaped rings 8 and hooks 9; the arc-shaped rings 8 are all arranged and fixedly sleeved on both sides of the padding layer 1, and the hooks 9 are respectively fixedly sleeved on the side of the side-flipping layer 2 away from the fixing mechanism; each hook 9 is hinged with a baffle, and a torsion spring is sleeved on the outside of the hinge axis of the baffle and the hook 9.

[0068] The specific implementation process is as follows: The arc-shaped ring 8 is arranged in multiple positions to adapt to different body shapes. After the hook 9 is attached to the arc-shaped ring 8, the torsion spring drives the baffle to automatically lock and prevent it from falling off. The coverage area of ​​the side flip layer 2 can be manually adjusted without tools. The structure is simple and easy to operate. The connection is stable and not easy to move, effectively improving the protective fit and adjustment efficiency.

[0069] Example 5, as shown in the appendix Figure 6 As shown, the difference from the above embodiments is that in some embodiments, a hook 9 ring design is used. Although this can reduce the number of operation steps by operating the knob screw 21, it also makes the operation steps more numerous by operating the hook 9. The detachable connection mechanism of this embodiment consists of several detachable main zippers 10 and secondary zippers 11. The main zippers 10 are all arranged and fixedly sewn to both sides of the edge of the padding layer 1, and the secondary zippers 11 are all fixedly sewn to the side of the side flipping layer 2 away from the fixing mechanism.

[0070] The specific implementation process is as follows: the main zipper 10 is arranged on the padding layer 1, and the secondary zipper 11 corresponds to the side flip layer 2. The zipper engagement enables quick disassembly and connection. The coverage of the side flip layer 2 can be manually adjusted without tools, and multiple positions can be used to adapt to different patient body shapes. The zipper connection is tight and not easy to shift, making the operation convenient and efficient, improving the protective fit and flexibility of use.

[0071] Example 6, as shown in the appendix Figure 7As shown, the difference from the above embodiments is that although the zipper design in some embodiments can reduce the operation steps of the side flipping layer 2, its adjustment range is limited and needs to correspond to the zipper position. In this embodiment, the detachable connection mechanism consists of several permanent magnets 12 and adsorption strips 13 that are magnetically coupled to each other; the permanent magnets 12 are respectively fixedly bonded to the bottom of the side flipping layer 2 on the side away from the fixing mechanism, and the adsorption strips 13 are arranged and fixedly bonded to both sides of the edge of the padding layer 1.

[0072] The specific implementation process is as follows: Through the magnetic cooperation between the permanent magnet 12 and the adsorption strip 13, adsorption and separation can be achieved without tools. The adsorption strip 13 is arranged in multiple positions to adjust the coverage of the side-flipping layer 2, with a wider adjustment range to suit different patient body shapes. The magnetic connection is stable and prevents displacement, making the operation convenient and efficient, and improving the protective fit and adjustment efficiency.

[0073] Example 7, as shown in the appendix Figure 9 As shown, the difference from the above embodiments is that in some embodiments, the locking device is fixed by the preload of the spring 14, which may result in insufficient fixing. In this embodiment, the locking device is an operating wrench 16 and an eccentric cam 17. The operating wrench 16 is integrally formed on the outer wall of the eccentric cam 17. The outer wall of the slider body 3 is fixedly bonded with a rotating shaft. The eccentric cam 17 and the rotating shaft are eccentrically rotated and engaged. The outer wall of the eccentric cam 17 contacts the slide groove.

[0074] The specific implementation process is as follows: The eccentric cam 17 is driven to rotate eccentrically around the shaft by the operating wrench 16. The locking and unlocking are achieved by changing the eccentricity. The manual operation is convenient without the need for tools. The outer wall of the cam is in close contact with the slide groove. The eccentric structure has strong locking ability, effectively preventing the lead skirt from shifting, ensuring the accurate and stable protection position, and improving the operating efficiency.

[0075] Example 8, as shown in the appendix Figure 10 As shown, the difference from the above embodiments is that in some embodiments, the locking device adopts an eccentric fixing design, which may lead to a decrease in fixing force under long-term use. The locking device in this embodiment is a pre-tightening knob 18 and a screw 19; the pre-tightening knob 18 and the screw 19 are coaxially fixed and bonded, the screw 19 is threadedly fitted on the slider body 3, and a rubber sleeve is fixedly bonded to the bottom end of the screw 19, and the rubber sleeve is in contact with the slide groove.

[0076] The specific implementation process is as follows: The drive screw 19 is manually rotated using the pre-tightening knob 18, which can be operated without tools, making it convenient and efficient; the threaded fit enables precise adjustment, and the rubber sleeve increases the friction with the slide groove, locking it securely and preventing displacement; the structure is simple and reliable, ensuring the lead skirt is stable in the target position, improving the accuracy of protection and operational efficiency.

[0077] The above specific embodiments are merely explanations of the present invention and are not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
