Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a drug injection table for nuclear medicine. Background Technology

[0002] Nuclear medicine is an emerging discipline that uses nuclear technology for the diagnosis, treatment, and research of diseases. It can be divided into two categories: clinical nuclear medicine and basic nuclear medicine (also known as experimental nuclear medicine). There are currently many bedside injection procedures available in nuclear medicine, such as cardiac blood pool imaging, renal dynamic imaging, and bone triphasics. At present, nuclear medicine drug injection tables are widely used for bedside injections. While existing nuclear medicine drug injection tables have improved the efficiency and effectiveness of bedside injections to some extent, some shortcomings still exist.

[0003] For example, patent document CN202421266827.2 discloses a nuclear medicine drug injection table that can fix the patient's arm by setting a fixing clamp, thereby solving the problem that the patient may move around during injection and affect the injection safety. The patient's arm placement angle can be adjusted by the use of electric push rod, push block, round rod and connecting rod to better expose the vein and make it easier for medical staff to find the appropriate injection site. However, this injection table does not take into account the need to shield the medical staff from nuclear radiation when injecting nuclear drugs, nor does it take into account the problem of hemostasis after injection. Moreover, the setting of a single fixing clamp is not enough to fix the patient's arm well, and there may still be safety problems caused by the arm moving around.

[0004] While the nuclear medicine drug injection table proposed in patent application CN202121151937.0 takes into account the hemostasis problem after nuclear medicine drug injection and the safety issues caused by arm movement, its hemostatic plate cannot work well with the rotating plate that holds the patient's arm. As a result, the hemostatic plate is not very effective after the rotating plate rotates. Furthermore, the injection table does not take into account the protection of medical staff or the comfort of injection for patients of different heights.

[0005] In other words, although the existing nuclear medicine drug injection table can solve some of the shortcomings of the injection process to a certain extent, it cannot fully take into account the injection safety of medical staff, nor can it fully take into account the injection comfort and safety of patients. There are still some shortcomings that need to be improved. Utility Model Content

[0030] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0031] Please see Figure 1-5In a preferred embodiment of this utility model, a drug injection table for nuclear medicine includes a table body 1. The tabletop of the table body 1 includes an injection tabletop 5 and a placement tabletop 4. The injection tabletop 5 and the placement tabletop 4 are rotatably configured. The injection tabletop 5 is provided with a placement plate 7 for placing an arm and a protective cover 6 framed on the outside of the placement plate 7. The placement plate 7 is provided with two fixing straps 8 and a tourniquet 9. The two fixing straps 8 are respectively located at both ends of the placement plate 7 along its length. The tourniquet 9 is slidably mounted on the placement plate 7 by a sliding member. The sliding member includes a sliding plate 13 and a locking structure 14. The sliding plate 13 is slidably inserted into the placement plate 7, and the sliding direction is the length direction of the placement plate 7. The two ends of the sliding plate 13 are respectively located on opposite sides of the placement plate 7. The sliding plate 13 has one end connected to one end of the tourniquet 9 and the other end detachably connected to the other end of the tourniquet 9. The other end of the sliding plate 13 is also provided with a locking structure 14 to prevent the sliding plate 13 from sliding on the placement plate 7. The protective cover 6 includes a front baffle, two side baffles and a top baffle. The front baffle is located on the outer side of one end in the length direction of the placement plate 7. The end of the front baffle is rotatably connected to the injection table 5 and is located on opposite sides of the placement plate 7. The two side baffles are located on opposite sides of the front baffle and on opposite sides in the width direction of the placement plate 7, and are spaced apart from the placement plate 7. Each side baffle is provided with an operating port. The top baffle is installed on top of the front baffle and the two side baffles. It is located directly above the placement plate 7 and is made of transparent radiation-proof material.

[0032] The injection table of this utility model is divided into an injection area and an item placement area by setting up an injection table board 5 and an item placement table board 4, which makes it convenient for medical staff to place items and administer nuclear medicine drugs to patients. The injection table 5 in the injection area can cover the patient's arm to be injected through a protective shield 6, avoiding nuclear radiation to medical staff. The protective shield 6 provides all-round protection for the patient by surrounding the patient on three sides and shielding the top. Medical staff can insert their hands through the operating port to perform the operation, which can greatly reduce the risk of nuclear radiation and improve the safety of medical staff during injection. Secondly, the injection table 5 uses a placement plate 7 to place the patient's arm to be injected. Two fixing straps 8 on the placement plate 7 can fix the patient's arm at two points. The two-point fixation method can effectively fix the patient's arm and greatly improve the stability of the arm fixation. Furthermore, a tourniquet 9 is also set on the placement plate 7. The tourniquet 9 can be used to compress and stop bleeding, which can avoid nuclear radiation to others caused by manual hemostasis, reduce manual workload, and greatly improve the convenience of injection. In addition, the position of the tourniquet 9 can be adjusted by sliding to match the injection position of different patients and achieve effective hemostasis. Therefore, the injection table of this invention can improve the efficiency of bedside injection in nuclear medicine, the comfort and safety of patients during injection, and the safety of medical staff. It has good performance and strong practicality.

[0033] Specifically, in this embodiment, the support legs 2 of the table body 1 are mounted on the table board via the connecting plate 3. The injection table board 5 and the placement table board 4 are both mounted on the connecting plate 3. One end of the injection table board 5 is rotatably connected to the placement table board 4. This end and the front baffle are located on opposite sides of the placement plate 7 along its length. That is, the injection table board 5 is supported and fixed by the connecting plate 3, and its tilt angle is changed by rotation. In this embodiment, a rotation drive 15 is installed on the connecting plate 3 to drive the injection table 5 to rotate relative to the placement table 4. The rotation drive 15 includes a drive screw 15.1, a drive slider 15.2, and a drive connecting rod 15.3. The drive screw 15.1 is rotatably mounted on the connecting plate 3, with its rotation axis parallel to the length direction of the placement plate 7. One end of the drive screw 15.1 is located on the outside of the connecting plate 3, and this end is on the same side as the side where the front baffle is located. The drive slider 15.2 is threaded onto the shaft of the drive screw 15.1. The drive slider 15.2 is also slidably connected to the connecting plate 3. One end of the drive connecting rod 15.3 is connected to the drive slider 15.2, and the other end is hinged to the injection table 5. In other words, the injection table 5 in this embodiment achieves tilt angle adjustment and maintains a certain tilt angle under the action of the rotation drive 15. The rotation drive 15 utilizes the rotation of the drive screw 15.1 to drive the drive slider 15.2 to slide linearly on the connecting plate 3, thereby causing one end of the drive connecting rod 15.3 to slide. This results in different tilt angles of the drive connecting rod 15.3, which in turn changes the tilt angle of the injection table 5 supported by the drive connecting rod 15.3, achieving the purpose of adjusting the tilt angle of the injection table 5. Preferably, an operating handle 15.4 is provided at the end of the drive screw 15.1 located outside the connecting plate 3 to facilitate turning the drive screw 15.1. To avoid the operating handle 15.4 affecting medical personnel, the operating handle 15.4 can also be slidably sleeved on the drive screw 15.1, shortening its length on the outside by sliding to the part directly below the connecting plate 3. The operating handle 15.4 can be pulled out when the drive screw 15.1 needs to be rotated. In addition, to facilitate the use of the injection table by patients of different heights, the support leg 2 is preferably a telescopic structure, so as to adjust the height of the table by telescopic means to meet the usage requirements of patients of different heights and improve the comfort of patients during injection.

[0034] In this invention, the patient's arm is placed on a placement plate 7 and secured by two fixing straps 8 on the placement plate 7. In this embodiment, one end of each fixing strap 8 is connected to one end of the placement plate 7 in the width direction, and the other end is detachably connected to the other end of the placement plate 7 in the width direction, so as to facilitate the fixing and loosening of the patient's arm. Preferably, the placement plate 7 is provided with a connecting ring, and the other end of the fixing strap 8 is movably threaded through the connecting ring. This other end is detachably connected by fastening the fixing strap 8 with Velcro, so as to facilitate fastening and fixing by Velcro, and to bind and fix the patient's arm of different thicknesses, adapting to different patients.

[0035] In this invention, the tourniquet 9 on the placement plate 7 can achieve pressure hemostasis, thus eliminating the need for manual pressure hemostasis by the patient or others. Considering the reusability of this invention, the hemostatic cotton 10 of the tourniquet 9 in this embodiment is detachably connected to the tourniquet body. This allows for the application of fresh hemostatic cotton 10 to different patients for pressure hemostasis. Preferably, the detachable connection between the hemostatic cotton 10 and the tourniquet body can be achieved through Velcro fastening, buckles, or other detachable connection methods. Furthermore, the hemostatic cotton 10 can cover only one side of the tourniquet 9, or it can cover the entire tourniquet 9 body through a connecting piece or other structure, thus providing comprehensive protection against contamination.

[0036] Furthermore, the tourniquet 9 of this invention is not fixedly installed on the placement plate 7. Its position can be adjusted on the placement plate 7 to meet the hemostatic compression requirements of different injection sites. In this invention, the tourniquet 9 achieves position adjustment and fixation after adjustment through a sliding member. Specifically, by unlocking the locking structure 14, the sliding plate 13 can slide on the placement plate 7, thereby driving the tourniquet 9 to slide. After sliding to the appropriate position, the locking structure 14 locks the sliding plate 13 relative to the placement plate 7, fixing the tourniquet 9 in its current position. Regarding the locking structure 14, in this embodiment, the locking structure 14 is located outside the placement plate 7 but framed within the protective cover 6. It includes a locking screw 14.1, a locking nut 14.2, a locking connecting plate 14.3, and an abutment rod 14.4. The locking screw 14.1 is located at one end of the sliding plate 13 and is arranged along the width direction of the placement plate 7. The locking screw 14.1... A locking nut 14.2 and a locking connecting plate 14.3 are fitted onto the rod. The locking nut 14.2 is threadedly connected to a locking screw 14.1, and the locking connecting plate 14.3 is movably connected to the locking screw 14.1. It is positioned between the locking nut 14.2 and the sliding plate 13. The locking connecting plate 14.3 is also rotatably connected to the locking nut 14.2 and is connected to one end of the abutment rod 14.4. The abutment rod 14.4 is slidably connected to the sliding plate 13, and the sliding direction is the width of the placement plate 7. The other end of the abutment rod 14.4 faces the side wall of the placement plate 7. Under the action of the locking nut 14.2, it abuts against the side wall of the placement plate 7 or moves away from the placement plate 7. That is, the locking structure 14 in this embodiment achieves unlocking and locking by rotating the locking nut 14.2 relative to the locking screw 14.1, causing the locking connecting plate 14.3 to slide relative to the sliding plate 13, thereby causing the abutment rod 14.4 on the locking connecting plate 14.3 to move away from or abut against the placement plate 7.

[0037] For the tourniquet 9, one end is detachably connected to the sliding plate 13, which allows the tourniquet 9 to be opened and connected when hemostasis is needed, thereby applying pressure to the patient's injection point for hemostasis. In this embodiment, the sliding plate 13 is provided with a U-shaped slot 12 for the tourniquet 9 to be inserted into. The other end of the tourniquet 9 is provided with a limiting block 11. When the tourniquet 9 is inserted into the U-shaped slot 12, the limiting block 11 abuts against the U-shaped slot 12 of the sliding plate 13. That is, the limiting block 11 is restricted by the locking position of the sliding plate 13 and cannot allow the tourniquet 9 to move towards the other end of the sliding plate 13. The tourniquet 9 then spans the placement plate 7 and can apply pressure to the patient's arm on the placement plate 7 for hemostasis.

[0038] Furthermore, in another embodiment of this utility model, the top surface of the placement plate 7 is an arc-shaped placement groove, on which a warm water pad is laid. Warm water is supplied to keep the patient's arm warm, preventing it from becoming too cold and improving the patient's comfort. Preferably, the warm water pad is detachably laid on the placement plate 7 and can be installed when needed.

[0039] Finally, it should be noted that casters can be installed on the support legs 2 for easy movement of the injection table; of course, they can also be omitted.

[0040] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
