Description

Technical Field

[0001] This utility model belongs to the field of safety protection technology, and in particular refers to an X-ray safety protection device for the human body, specifically a wearable mobile radiation protection cabin that can be used in fields such as medical research. Background Technology

[0002] Interventional radiology originated in the 1960s and developed rapidly in China after the 1980s. Interventional minimally invasive treatment has developed into another major system after internal medicine and surgery. The core of interventional treatment is to perform puncture and catheterization to the lesion requiring treatment under the precise guidance of modern imaging equipment in order to achieve the purpose of diagnosis and treatment.

[0003] Interventional surgery, characterized by minimal invasiveness, rapid healing, and precise interventional site selection, is increasingly widely used in cardiology, oncology, obstetrics and gynecology, neurosurgery, and orthopedics. However, all interventional surgeries come at the cost of the surgeon's health, as exposure to X-ray radiation can be harmful. During interventional procedures, to prevent radiation damage, surgeons must wear very heavy lead aprons, lead neck protectors, lead caps, and lead goggles. A 2014 occupational health survey conducted by the American College of Cardiovascular Angiography and Interventional Medicine (ACAI) found that among those with an average of 16 years of experience in cardiac interventional work, half suffered from orthopedic-related diseases due to years of heavy lifting, with lumbar spine injuries being the most common (24.7%), followed by bone and joint injuries (19.6%).

[0004] Currently, the number of interventional surgeries worldwide is increasing dramatically, but the burden on doctors' shoulders has not lessened. Many interventional surgeons stand for 6-8 hours a day. Under this workload, the damage caused to their bodies by heavy lead aprons and other protective equipment is no less than the damage caused by scattered radiation. Although some new protective cabins and other devices can provide more comprehensive protection for staff in radiation environments, their large size significantly hinders doctors' operations in the operating room and cannot completely and effectively solve the practical protection problem for interventional surgeons during procedures. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a wearable mobile radiation protection cabin. This cabin is compact, fits well, is comfortable, easy to use, weightless, and flexible in movement without affecting operation. It can effectively prevent X-rays from harming interventional doctors or researchers.

[0006] The objective of this utility model is achieved through the following technical solution: A wearable mobile radiation protection cabin is characterized in that: the cabin includes a protective half-cabin for accommodating the user and a flexible protective upper garment worn on the user's upper body. The protective half-cabin includes a protective cabin body and three support legs for supporting the protective cabin body. One support leg is located in front of the user and between the user's two legs, and the other two support legs are located to the user's left rear and right rear, respectively.

[0007] The supporting legs are outwardly flared relative to the protective cabin, and casters are installed at the bottom of the supporting legs.

[0008] The height of the support leg is adjustable.

[0009] The bottom of the support leg located in front of the user bends inward to form a mounting platform, and a pair of casters are installed at the bottom of the mounting platform.

[0010] The support legs located to the left rear and right rear of the user have only one caster at the bottom; or the support legs located to the left rear and right rear of the user have their bottoms bent inwards to form a mounting platform, with a pair of casters installed at the bottom of the mounting platform.

[0011] The bottom of the support legs located to the left rear and right rear of the user are bent inward to form a mounting platform. A pair of casters are installed at the bottom of the mounting platform, while the bottom of the support leg located in front of the user is equipped with only one caster.

[0012] The protective cabin located at the user's waist and abdomen has an upward-tightening structure that is smaller at the top and larger at the bottom. A door is arranged at the rear or side of the protective cabin, and the door is installed at the opening end of the protective cabin via a damping hinge. The door is located between the user's left rear support leg and right rear support leg, or between the user's left rear support leg and front support leg, or between the user's right rear support leg and front support leg.

[0013] The protective enclosure includes an upper open ring, a connector, and a lower open ring. The lower open ring is larger than the upper open ring and is located in front of the user. The lower open ring has the largest increase in size relative to the upper open ring. The upper and lower open rings are connected by a single connector or multiple connectors, and the connector is inclined outward relative to the upper open ring.

[0014] The components of the protective cabin are integrally formed, that is, the upper and lower open rings are connected by multiple connectors to form an integral structure; or because the connectors used are integral structures, the protective cabin as a whole presents a C-shaped structure.

[0015] The upper open ring has a C-shaped structure, and the lower open ring has a C-shaped structure.

[0016] The protective cabin is an open ring structure, with the inner diameter of the upper opening being smaller than the inner diameter of the lower opening, forming a hollow, irregularly shaped frustum-shaped structure with an opening at the rear or side.

[0017] Flexible buffers are arranged on the inner walls of the upper and lower open rings; or flexible buffers are arranged on the inner and outer walls of the upper and lower open rings and the connecting parts.

[0018] The protective semi-cabin includes a protective enclosure, which is hung on the protective cabin body, and the lower edge of the protective enclosure outside the protective cabin body is located at the casters of the supporting legs.

[0019] The protective enclosure includes an outer protective enclosure and an inner protective enclosure. The upper edges of the outer protective enclosure and the upper edges of the inner protective enclosure are connected to form an integral structure. The outer protective enclosure is made of a single piece of flexible protective material, and the inner protective enclosure is composed of multiple pieces of flexible protective material with overlapping at the joints of adjacent pieces. The purpose of using multiple pieces of flexible protective material for the inner protective enclosure is to avoid restricting the user's legs when walking.

[0020] The inner top of the protective enclosure inside the protective cabin is provided with a flexible waist-linkage connector that can be bent. The lower part of the flexible waist-linkage connector can be bent upward to form a U-shaped or inverted J-shaped groove structure. This groove structure is used to accommodate the lower part of the flexible protective upper garment to support part of the weight of the flexible protective upper garment, and the overlapping part of the flexible protective upper garment and the flexible waist-linkage connector can enhance the protection.

[0021] The inner side of the groove structure is equipped with a waist belt to bind the bent part of the waist linkage flexible connector to the user's waist, so that the protective half-cabin can change synchronously with the user's body movement.

[0022] The protective cabin also includes a waist and abdomen protective wing, which is fixed to the upper edge of the protective enclosure outside the protective cabin. The waist and abdomen protective wing extends upward to strengthen the protection of the user's waist and abdomen, and the two ends of the waist and abdomen protective wing extend to the cabin door of the protective cabin, so that the waist and abdomen protective wing can open with the cabin door and close with the cabin door.

[0023] The protective materials installed on this protective cabin include: a flexible protective superstructure, protective barriers, a waist-level flexible connector, and waist- and abdomen-level protective wings. The flexible protective superstructure and protective barriers are essential basic protective materials. The waist-level flexible connector is a better option for supporting the flexible protective superstructure to distribute weight and enhance protection. The waist- and abdomen-level protective wings are an even better option based on the waist-level flexible connector. In actual use, the protective barriers are divided into outer and inner protective barriers. The lower edge of the essential outer protective barrier must reach the casters to provide overall protection below the waist and abdomen. The inner protective barrier, which enhances protective performance, can be positioned between the waist and abdomen and the knees (reducing the overall weight of the equipment while enhancing protective performance).

[0024] The protective materials installed on the protective cabin are all made of flexible protective materials with a lead equivalent of not less than 0.25 mmPb.

[0025] Compared with the prior art, the present invention has the following advantages: 1. Significantly reduce the user's physical load: The entire weight of the protective semi-cabin is supported by the support legs, and the user does not need to bear any weight of the protective semi-cabin; the flexible protective upper garment can be made shorter than the traditional lead apron upper garment, and most of its weight is borne by the U-shaped or inverted J-shaped groove structure, so the user's body only needs to bear a part of the weight, thereby significantly reducing the user's physical load.

[0026] 2. Significantly improves radiation protection effectiveness: Since the majority of the weight of the protective material is borne by the cabin itself, protective materials with a higher lead equivalent can be used, resulting in a radiation protection effect that is significantly higher than that of traditional lead aprons.

[0027] 3. Improve user comfort: The protective materials of the flexible protective top and the protective half-cabin do not need to be in close contact with the user's body, making them more comfortable to wear compared to traditional lead aprons; 4. Enhanced user mobility and versatility: One support leg for the protective cabin is positioned in front of the user and between their legs, while the other two support legs are located to the user's left and right rear, respectively. This design maximizes the space for the user to move forward, backward, left, and right, minimizing the risk of bumping into the user's feet while walking and making movement more flexible. Furthermore, the overall weight of the protective cabin is between 10 kg and 25 kg, allowing users to easily lift it over thresholds when moving between the operating room and the monitoring room, thus improving mobility and versatility.

[0028] 5. Significantly reduce the overall volume of the protective cabin: Interventional operating rooms have many devices and people, and many surgeries require two doctors to stand side by side to operate. The structure of the support legs being slightly extended outward relative to the protective cabin body and the bottom of the support legs being bent inward to form a mounting platform for installing casters can significantly reduce the overall volume of the protective cabin to 50% to 80% of the volume of other protective cabins on the market, making this protective cabin applicable to various complex surgical scenarios.

The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0032] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0033] like Figure 1-8 As shown: A wearable mobile radiation protection cabin, the cabin includes a protective half-cabin 1 for accommodating the user and a flexible protective upper garment 2 worn on the user's upper body. The protective half-cabin 1 includes a protective cabin body 10, three support legs 11 for supporting the protective cabin body 10, a cabin door 12, a protective enclosure 13, a waist linkage flexible connector 14, and a waist belt.

[0034] like Figure 3-6 As shown: The protective cabin 10 located at the user's waist and abdomen has an upwardly tapering structure that is smaller at the top and larger at the bottom. A door 12 is arranged at the rear or side of the protective cabin 10. The door 12 is installed at the opening end of the protective cabin 10 via a damping hinge. The protective cabin 10 includes an integrally formed upper opening ring 100, a connecting piece 101, and a lower opening ring 102. The lower opening ring 102 is larger than the upper opening ring 100 and is located in front of the user. The lower opening ring 102 has the largest increase in size relative to the upper opening ring 100. The upper opening ring 100 and the lower opening ring 102 are connected by a single piece. One or more connectors 101 are connected together, and the connectors 101 are inclined outward relative to the upper opening ring 100; the protective enclosure 13 is hung on the protective cabin 10, and the lower edge of the protective enclosure 13 outside the protective cabin 10 is located at the caster 110 of the support leg 11. Furthermore, the protective enclosure 13 can be divided into an outer protective enclosure and an inner protective enclosure. The lower edge of the necessary outer protective enclosure should fall at the caster 110 to provide overall protection below the waist and abdomen. The inner protective enclosure, which enhances the protective performance, can be arranged between the waist and abdomen and the knee.

[0035] A special feature of the protective semi-cabin 1 provided by this utility model is that a flexible waist-linking connector 14 is arranged on the top inner side of the protective enclosure 13 inside the protective cabin 10. The lower part of the flexible waist-linking connector 14 can be bent upward to form a U-shaped or inverted J-shaped groove structure 140. The groove structure 140 is used to accommodate the lower hem of the flexible protective upper garment 2 to support part of the weight of the flexible protective upper garment 2, and the overlapping part of the flexible protective upper garment 2 and the flexible waist-linking connector 14 can enhance protection. In use, a waist belt 15 is used on the inner side of the groove structure 140 to bind the bent part of the flexible waist-linking connector 14 to the user's body, so that the protective semi-cabin 1 can change synchronously with the user's body movements.

[0036] In the above structure, the two ends of the opening of the waist linkage flexible connector 14 are connected by connectors. After the connectors are connected, the two ends of the opening of the waist linkage flexible connector 14 are closed, so that the waist linkage flexible connector 14 forms a ring. The connectors can be Velcro, hooks, buckles and other structures that are easy to connect.

[0037] like Figure 3-6 As shown: Three support legs 11 are arranged in a triangular pattern at the bottom of the protective cabin 10. One support leg 11 is located in front of the user and between the user's two legs, and the other two support legs 11 are located to the left rear and right rear of the user, respectively. The height-adjustable support legs 11 have an outward expansion structure relative to the protective cabin 10, and casters 110 are installed at the bottom of the support legs 11. The upper vertical part of the support legs 11 can be adjusted in height, and the lower part has an outward expansion structure. There are several possible installation structures for the casters 110. For example, one structure involves the bottom of the support leg 11 located in front of the user bending inwards to form a mounting platform 111, with a pair of casters 110 mounted on the bottom of the mounting platform 111. The support legs 11 located to the user's left rear and right rear have only one caster 110 mounted on their bottoms. Alternatively, the bottoms of the support legs 11 located to the user's left rear and right rear are both bent inwards to form mounting platforms 111, with a pair of casters 110 mounted on their bottoms. Another structure involves the bottoms of the support legs 11 located to the user's left rear and right rear are both bent inwards to form mounting platforms 111, with a pair of casters 110 mounted on their bottoms, and the support leg 11 located in front of the user has only one caster 110 mounted on its bottom. These three examples are for reference only, and the installation method of the casters 110 provided by this utility model is not limited to these three structures.

[0038] In the above Figures 1-8 In the structure shown: the hatch 12 is located between the support leg 11 on the left rear of the user and the support leg 11 on the right rear of the user; however, in actual use, the hatch 12 can also be located between the support leg 11 on the left rear of the user and the support leg 11 in front of the user, or between the support leg 11 on the right rear of the user and the support leg 11 in front of the user, as needed.

[0039] In addition, to prevent wear between the protective cabin 10 and the protective enclosure 13, flexible buffers are arranged on the inner walls of the upper opening ring 100 and the lower opening ring 102; or flexible buffers are arranged on both the inner and outer walls of the upper opening ring 100 and the lower opening ring 102.

[0040] like Figure 1-2As shown, in order to improve the protection performance of the human waist and abdomen, the protective cabin also includes a waist and abdomen protective wing 3. The waist and abdomen protective wing 3 is fixed to the upper edge of the protective enclosure 13 outside the protective cabin body 10. The waist and abdomen protective wing 3 extends upward to strengthen the protection of the user's waist and abdomen, and the two ends of the waist and abdomen protective wing 3 extend to the cabin door 12 of the protective cabin body 10 respectively.

[0041] The method of using the wearable mobile radiation protection cabin provided by this utility model is as follows: Before surgery, open the door 12 of the protective semi-chamber 1, enter the protective semi-chamber 1, close the door 12, stand on tiptoe, and manually pull up the bottom of the waist linkage flexible connector 14. Connect the two ends of the opening of the waist linkage flexible connector 14 with connectors, and then tie on the waist belt 15. After stepping down, the waist linkage flexible connector 14 forms a groove structure 140. Put on the flexible protective upper garment 2, with the hem of the flexible protective upper garment 2 falling into the groove structure 140. Disinfect hands and put on a sterile isolation gown. After the surgery is completed, the user removes the sterile isolation gown, then stands on tiptoe to remove the waist belt 15, opens the door 12 to leave the protective semi-chamber 1, and removes the flexible protective upper garment 2.

[0042] It should be noted that some surgeries require frequent crossing of thresholds. During the surgery, the user can easily cross the threshold by holding the upper opening ring 100 or the lower opening ring 102 of the protective cabin 10.

[0043] The door 12 of the wearable mobile radiation protection cabin provided by this utility model is arranged at the rear of the protective cabin body 10. In fact, it can also be arranged on the side.

[0044] The entire weight of the protective semi-cabin 1 provided by this utility model is supported by the supporting legs 11, so the user does not need to bear any weight of the protective semi-cabin 1. The flexible protective upper garment 2 can be made shorter than the traditional lead apron upper garment, and most of its weight is borne by the U-shaped or inverted J-shaped groove structure 140, so the user's body only needs to bear a part of the weight, thereby greatly reducing the user's physical load. One supporting leg 11 for supporting the protective cabin 10 is located in front of the user and between the user's two legs, and the other two supporting legs 11 are located to the left rear and right rear of the user, respectively. This design structure maximizes the space for the user to move forward, backward, left and right, and the user's feet will hardly be bumped when walking, and the movement is more flexible. In addition, the overall weight of the protective cabin is between 10 kg and 25 kg, which allows the user to easily lift it over the threshold when moving between the operating room and the monitoring room, improving the flexibility of movement and the universality of use.
