Description

Technical Field

[0001] This utility model relates to the field of radiation protection equipment technology, and in particular to a radiation drug administration protection device. Background Technology

[0002] With the popularization of nuclear medicine technology, radiopharmaceuticals are increasingly used in disease diagnosis and treatment. These procedures involve radiation, requiring strict protection for medical personnel. Currently, commonly used protective devices are mostly fixed or movable protective screens with lead glass observation windows and operating ports. For example, Chinese patent CN216754860U discloses a protective device for administering nuclear medicine radiopharmaceuticals, which uses a protective panel with an operating chamber for protection, allowing medical personnel to administer the medication through an operating window on the side of the chamber.

[0003] However, the drug administration protective device described in the aforementioned patent documents has significant drawbacks: its operating chamber is an open or semi-open channel, allowing both medical personnel and patients to simultaneously insert their hands into the chamber from both ends. During drug administration, especially when the patient's arm moves due to tension or poor cooperation, direct contact with the medical personnel's hands is highly likely, posing risks of radiation and cross-infection. More seriously, if the medical personnel's gloves are contaminated with trace amounts of radioactive drug, direct contact could lead to radioactive contamination of the patient's non-target skin. Utility Model Content

[0004] This invention provides a protective device for administering radiopharmaceuticals, and the technical problem to be solved is to avoid direct contact between medical personnel and patients during drug administration.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A radiopharmaceutical administration protective device includes a support frame, a protective plate, and an operating chamber. The support frame is equipped with casters at its lower end. The protective plate is slidably mounted on the support frame. The operating chamber includes a chamber body, a baffle, and a cover. The chamber body is fixedly mounted on the protective plate, and has drug delivery slots penetrating both sides of the protective plate at its upper ends. The baffle is located at the front end of the chamber body, with one end hinged to the chamber body, and can close or flip open the front opening of the drug delivery slot. The cover is slidably mounted on the chamber body and can close or slide open the rear end of the drug delivery slot. The baffle is positioned precisely on the sliding path of the cover, and when the baffle flips open, it blocks the sliding path of the cover, thereby restricting the sliding of the cover.

[0007] As a further improvement to the above technical solution:

[0008] In at least one embodiment, a rotating shaft is provided at one end of the baffle, which can only slide relative to the baffle. A rotating seat is provided at the front end of the compartment. The baffle is rotatably connected to the rotating seat via the rotating shaft. A regular polygonal block is provided at one end of the rotating shaft, and a boss and a spring are provided at the other end. The spring is sleeved on the rotating shaft, and its two ends abut against the boss and the rotating seat respectively. A regular polygonal groove matching the regular polygonal block is also provided at the end of the rotating seat adjacent to the regular polygonal block. Under the action of the spring, the regular polygonal block can be inserted into the regular polygonal groove, which can keep the baffle in the open state and can limit and fix the baffle to prevent the patient from pushing the cover forcefully, causing the baffle to flip and close.

[0009] Furthermore, in at least one embodiment, at least one plane is provided on the outer side wall of the rotating shaft, and a connecting groove with the same cross-sectional shape as the rotating shaft is provided at one end of the baffle. The rotating shaft is slidably disposed in the connecting groove and slidably connected with the baffle, so that the rotating shaft can slide freely along its axial direction in the connecting groove, but cannot rotate relative to the baffle around its own axis, thereby realizing the sliding connection and synchronous rotation between the rotating shaft and the baffle.

[0010] Furthermore, in at least one embodiment, the lower end face of the chamber is a downwardly convex arc-shaped surface, which facilitates the medication placed in the administration slot to slide down to the bottom of the administration slot, making it easier for the patient to take the medication and also making it easier to clean the administration slot.

[0011] Furthermore, in at least one embodiment, the protective panel is also provided with an observation window, which is located above the operating compartment, to facilitate medical staff to observe the patient's medication dispensing process.

[0012] Furthermore, in at least one embodiment, the support frame has columns at both ends on its upper side, and horizontal connecting rods are provided on the columns. The protective plate has sliding sleeves at both ends on its inner side. These sliding sleeves are slidably fitted onto the columns at both ends of the support frame, and limit bolts are threaded onto the sliding sleeves. The columns have several limit holes spaced apart along their height direction, and the limit bolts can be engaged into these limit holes to fix the protective plate relative to the support frame. This allows for adjustment of the height of the operating compartment on the protective plate, adapting to different medical personnel.

[0013] Furthermore, in at least one embodiment, both ends of the protective plate are provided with extensions that bend towards the front end, thereby increasing the protective area and wrapping and protecting the medical staff's body.

[0014] Furthermore, in at least one embodiment, the lower end of the protective plate is provided with an extension plate that matches the shape of the protective plate. The outer side of the protective plate is provided with a limiting ring that fits against the outer side of the extension plate. One end of the extension plate is inserted into the limiting ring and slidably connected to the protective plate, and the other end is provided with a hook. The extension plate can be suspended and fixed on the horizontal connecting rod through the hook. The gap between the protective plate and the ground can be protected through the extension plate.

[0015] Furthermore, in at least one embodiment, handles are provided on the inner sides of both the protective plate and the extension plate to facilitate adjustment and movement of the protective plate and the extension plate.

[0016] Compared with the prior art, the present invention achieves at least the following beneficial effects: The radiopharmaceutical administration protective device of the present invention interlocks the baffles and covers at both ends of the operating chamber, so that when medical staff put out the medicine and when the patient takes out the medicine, the hands of medical staff and the patient are always physically isolated and cannot be put into the administration tank at the same time, thus avoiding direct contact.

However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0024] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.

[0025] To address the drawback of existing technologies that involve direct hand contact between patients and medical staff during drug administration, the inventors, after careful analysis, discovered that the main reason for this problem in existing protective devices is that their operating chamber is an open or semi-open passage, allowing both medical staff and patients to simultaneously enter the chamber from either end. Based on this analysis, the inventors have made structural improvements to the radiopharmaceutical administration protective device.

[0026] like Figure 1-4 As shown, a radiopharmaceutical administration protective device of the present invention includes a support frame 1, a protective plate 2, and an operating chamber 3.

[0027] The support frame 1 serves as the installation base for the device. Four casters 11 with brakes are installed at the bottom of the support frame 1 to facilitate the movement and fixation of the protective device. Two columns 12 are vertically fixed on both sides of the upper part of the support frame 1. The top of the columns 12 is connected and reinforced by a horizontal connecting rod 13. Multiple limiting holes 121 are spaced apart on the columns 12 along the vertical direction.

[0028] The protective plate 2 is a radiation shielding plate with lead lining. A sliding sleeve 22 is fixedly installed on each side of its front end (medical side). The sliding sleeve 22 is fitted onto the corresponding column 12, so that the protective plate 2 can slide up and down along the column 12. A limit bolt 23 is screwed on the sliding sleeve 22. When the protective plate 2 is adjusted to a suitable height, the limit bolt 23 is tightened so that its end is inserted into the limit hole 121 of the current height, and the protective plate 2 can be locked and fixed.

[0029] The protective plate 2 has two ends bent forward (towards the medical staff) to form extensions 24 for side protection. A lead glass observation window 21 is installed on the upper part of the protective plate 2. An extension plate 25 is slidably connected to the lower part of the protective plate 2 via a limiting ring 26. The extension plate 25 can slide downwards to cover the gap between the protective plate 2 and the ground. When not in use, it can be pulled upwards to detach from the ground and hung on a horizontal connecting rod 13 via a hook 251 at its top. Both the protective plate 2 and the extension plate 25 are equipped with handles 252 for easy manipulation to change their position.

[0030] Preferably, the limiting ring 26 is a C-shaped steel ring fixed to the back of the protective plate 2, and its inner wall is in clearance fit with the outer side of the extension plate 25, which allows the extension plate 25 to slide up and down, and provides sufficient guidance and support.

[0031] The operating chamber 3 includes a chamber body 31, a baffle 32, and a cover 33. The chamber body 31 is fixed to the protective plate 2 and has through-hole drug delivery channels 311 at both ends of its upper side. The front end (medical side) of the chamber body 31 is hinged to the baffle 32, and the rear end (patient side) is fitted with a sliding cover 33 that can slide back and forth via a groove. The rotation path of the baffle 32 and the sliding path of the cover 33 overlap spatially. When the baffle 32 is closed, its upper surface is flush with the lower surface of the cover 33. Therefore, when the baffle 32 is flipped outward to 90°, it can vertically block the front end of the cover 33, preventing the cover 33 from sliding open. Conversely, when the baffle 32 is closed, the cover 33 can open and close freely. Preferably, the upper edge of the drug delivery channel 311 is provided with a flexible radiation-proof curtain to further reduce radiation scattering.

[0032] Optionally, the rear end of the drug delivery tank 311 is provided with two horizontally parallel guide rails, and the cover plate 33 is provided with sliders that match the guide rails on both sides. The sliders can be slidably inserted into the guide rails, so that the cover plate 33 can slide back and forth along the guide rails.

[0033] A connecting groove 321 is provided at one end of the baffle 32 that is hinged to the chamber 31. A pivot 34 for hinge is provided in the connecting groove 321. At least one plane 344 is provided on the outer side wall of the pivot 34. In this embodiment, the cross-section of the pivot 34 is "D" shaped, and the shape of the connecting groove 321 matches it, so that the pivot 34 can slide freely along its axial direction in the connecting groove 321, but cannot rotate relative to the baffle 32 around its own axis, thereby realizing the sliding connection and synchronous rotation between the pivot 34 and the baffle 32.

[0034] A rotating seat 312 is fixed at the front end of the chamber 31. One end of the rotating shaft 34 is formed with a regular polygon block 341, and the other end is provided with a boss 342 and a spring 343. The rotating shaft 34 passes through the rotating seat 312, and the spring 343 is compressed between the boss 342 and the rotating seat 312, thereby always applying a preload force towards the boss 342 end to the rotating shaft 34. The inner end face of the rotating seat 312 has a regular polygon groove 313 that matches the shape of the regular polygon block 341. Under the push of the spring 343, when the regular polygon block 341 is aligned with the regular polygon groove 313, the regular polygon block 341 will be locked into the regular polygon groove 313 to achieve limit fixation and prevent the patient from pushing the cover 33 too hard, causing the baffle 32 to be forced to close.

[0035] When it is necessary to rotate the baffle 32, only a slight force is needed to overcome the force of the spring 343, causing the regular polygonal block 341 to disengage from the regular polygonal slot 313, thus allowing the baffle 32 to rotate. Furthermore, the axial length of the connecting slot 321 is designed to be greater than or equal to the sum of the insertion depth of the regular polygonal block 341 and the compression stroke of the spring 343, to ensure reliable limiting and fixing.

[0036] In addition, the bottom of the compartment 31 is designed as a downward-convex arc surface 314, which allows the medicine to slide to the lowest point and is easy to clean.

[0037] When in use, medical staff adjust the protective plate 2 to a suitable height according to their own height and lock it. After sliding the extension plate 25 upward off the ground, it is fixed to the horizontal connecting rod 13 by the hook 251. Then, the device is pushed to the side of the bed so that the operating chamber 3 faces the patient. Then the extension plate 25 is lowered to protect the gap between the protective plate 2 and the ground.

[0038] Medical staff first push the cover 33 back to close the rear end of the medication delivery slot 311, then press the pivot 34 towards the end of the regular polygon block 341 to disengage the regular polygon block 341 from the regular polygon slot 313. Next, the baffle 32 is flipped open to a 90° position. After releasing the pivot 34, the regular polygon block 341 is re-engaged into the regular polygon slot 313 under the action of the spring 343, thus limiting and fixing the baffle 32. Medical staff then place the medication into the medication delivery slot 311 through the front opening. Under the action of the arc-shaped surface 314 at the bottom of the chamber 31, the medication automatically slides to the bottom. At this point, the cover 33 is locked and cannot be opened because its sliding path is blocked. After the medication is placed, the medical staff flips the baffle 32 to close it. Only then can the patient slide the cover 33 to open the rear end of the medication delivery slot 311, allowing the patient to insert their arm into the operating chamber 3 to retrieve the medication.

[0039] Medical staff are positioned behind the protective panel 2 and observe the patient taking medication through the observation window 21. Since the cover 33 cannot be opened when the baffle 32 is opened, the baffle and the cover are interlocked. Therefore, when medical staff are dispensing medication and when patients are taking medication, the hands of medical staff and patients are always physically isolated and cannot be simultaneously inserted into the medication dispenser 311, thus avoiding direct contact.

[0040] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
