Description

Technical Field

[0001] This utility model relates to medical devices, and more particularly to an abdominal subcutaneous injection card. Background Technology

[0002] In the medical field, subcutaneous abdominal injection is a common method of drug administration, widely used in scenarios such as insulin injection for diabetic patients. However, traditional subcutaneous abdominal injections often present several challenges for patients. Firstly, due to the lack of precise positioning tools, the choice of injection site is largely random. Repeated injections at the same site over a long period can easily lead to local tissue lesions, such as fat hyperplasia and induration, severely affecting drug absorption efficiency and resulting in unstable blood sugar control.

[0003] On the other hand, the situation is even more challenging for patients with enterostomies and diabetes. Enterostomies alter a patient's normal physiological structure, requiring extra care to avoid the stoma area during subcutaneous injections in the abdomen to prevent serious complications such as infection. However, relying solely on the experience and judgment of medical staff or patients makes precise avoidance difficult, increasing medical risks. Furthermore, maintaining a stable injection site during daily activities is also a significant challenge for these patients.

[0004] Currently, there is a lack of a specialized abdominal subcutaneous injection aid that integrates multiple functions such as precise positioning, convenient fixation, and stoma protection, specifically designed for this particular need. This provides an urgent practical need and space for technological innovation in the development of this abdominal subcutaneous injection card. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide precise positioning and zoned injection, thereby improving injection safety and standardization; another purpose of this utility model is to provide a multifunctional design to meet the needs of special patients.

[0006] Technical solution: An abdominal subcutaneous injection card includes an arc-shaped card. The upper surface of the arc-shaped card has a rotating groove. A rotating rod is rotatably connected inside the rotating groove. The front end of the rotating rod extends through to the front surface of the arc-shaped card. A disc is fixedly connected to the outer wall of the rotating rod on the front surface of the arc-shaped card. A hollow groove is formed on the front surface of the disc. Multiple injection ports are formed on the upper surface of the arc-shaped card. A baffle is provided inside each injection port. A breakable wire is symmetrically fixedly connected to the outer wall of the baffle.

[0007] Furthermore, a limiting block is fixedly connected to the outer wall of the rotating rod inside the rotating groove. A spring groove is formed on the upper surface of the limiting block. A sliding plate is slidably connected inside the spring groove. An extension rod is fixedly connected to the upper surface of the sliding plate. A spring is fixedly connected between the lower surface of the sliding plate and the lower inner surface of the spring groove. A wedge-shaped locking block is fixedly connected to the top of the extension rod. A pair of locking slots are symmetrically formed on the inner side wall of the rotating groove. The wedge-shaped locking block is engaged with the inside of the locking slot.

[0008] Furthermore, the outer side wall of the arc-shaped card is symmetrically fixedly connected with a fixing block. The front surface of the fixing block is provided with a through-hole. The outer side wall of the left fixing block is engaged with a left waist belt, and the outer side wall of the right fixing block is engaged with a right waist belt. The front surfaces of the left and right waist belts are provided with circular grooves, and the grooves and the interiors of the adjacent circular holes are engaged with locking pins.

[0009] Furthermore, the lower left side of the right waist belt has a Velcro fastener, and the upper right side of the left waist belt has a backing layer, with the Velcro fastener and the backing layer being bonded together.

[0010] Furthermore, multiple writing boards are fixedly connected to the outer wall of the hollowed-out groove on the front surface of the disc, and soft pads are fixedly connected to the inner walls of the right waist belt and the left waist belt.

[0011] Furthermore, the outer wall of the rotating rod is symmetrically and fixedly connected with anti-slip blocks on the outer wall of the disc, and a groove is provided at the front end of the rotating rod, with a plug plate engaged inside the groove.

[0012] Beneficial effects: When the disc rotates, the wedge-shaped locking block engages with the slot, ensuring accurate alignment of the perforated groove with the required injection site. This avoids the positional deviation problems that may occur in traditional injections. For patients requiring long-term subcutaneous abdominal injections, such as diabetic patients, standardized injection sites are crucial. Repeated injections at the same site may lead to complications such as local tissue induration and fat atrophy, affecting drug absorption. The multiple injection ports of this injection card allow for the classification of different injection sites. Medical staff or patients can use each injection port in a specific order, ensuring rotation of injection sites, effectively reducing the risk of complications, and improving the safety and effectiveness of injections.

[0013] This injection card boasts multiple practical functions, meeting the needs of special groups such as patients with enterostomies and diabetes. Firstly, the design of the left and right waistbands, Velcro, and adhesive layers securely fastens the curved card to the patient's abdomen, while the inner padding enhances comfort, facilitating injections during daily activities. Secondly, it innovatively designates one injection port as the stoma observation port, utilizing grooves and a sealing plate to protect the stoma and prevent unnecessary impact on the enterostomy area.

[0021] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figures 1-6As shown, an abdominal subcutaneous injection card is provided, including an arc-shaped card 1. A rotating groove 2 is provided on the upper surface of the arc-shaped card 1. A rotating rod 3 is rotatably connected inside the rotating groove 2. The front end of the rotating rod 3 extends through to the front surface of the arc-shaped card 1. A disc 4 is fixedly connected to the outer wall of the rotating rod 3 on the front surface of the arc-shaped card 1. A hollow groove 5 is provided on the front surface of the disc 4. Multiple injection ports 6 are provided on the upper surface of the arc-shaped card 1. A baffle 7 is provided inside each injection port 6. A breakable wire 8 is symmetrically fixedly connected to the outer wall of the baffle 7.

[0024] When using the abdominal subcutaneous injection card, first gently place the curved card 1 against the patient's abdominal skin; its unique curved design perfectly adapts to the abdominal curve. Next, rotate the disc 4. Because the disc 4 is fixedly connected to the rotating rod 3, and the rotating rod 3 can rotate flexibly within the rotating groove 2, rotating the disc 4 will cause the rotating rod 3 to rotate synchronously within the rotating groove 2. The core purpose of rotating the disc 4 is to precisely align the perforated groove 5 on the front surface of the disc 4 with the desired injection port 6. Once the perforated groove 5 is successfully aligned with the selected injection port 6, the injection port 6 is immediately operational, and medical personnel can then prepare to perform the subcutaneous injection. Because the injection port 6 has a retainer 7 inside, and the retainer 7 is connected to the injection port 6 by symmetrical breakable wires 8, the retainer 7 can be removed before the injection process. This will cause the breakable wires 8 to break, allowing the retainer 7 to be easily removed, thus creating favorable conditions for the syringe to perform the subcutaneous injection accurately. After the injection is completed, if it is necessary to change the injection position, rotate the disc 4 again to align the hollow groove 5 with the new injection port 6, and then repeat the above injection process to classify the different injection positions.

[0025] In this embodiment, the outer side wall of the rotating rod 3 is fixedly connected to the inner side wall of the rotating groove 2. The upper surface of the limiting block 9 is provided with a spring groove 10. The inner side wall of the spring groove 10 is slidably connected to the sliding plate 11. The upper surface of the sliding plate 11 is fixedly connected to the extension rod 12. The lower surface of the sliding plate 11 and the inner lower surface of the spring groove 10 are fixedly connected to the spring 13. The top end of the extension rod 12 is fixedly connected to the wedge-shaped locking block 26. The inner side wall of the rotating groove 2 is symmetrically provided with a pair of locking grooves 14. The wedge-shaped locking block 26 is engaged with the inner side wall of the locking groove 14.

[0026] First, place the arc-shaped card 1 against the patient's abdominal skin. Rotate the disc 4, and the rotating rod 3 will rotate accordingly within the rotating groove 2. The limiting block 9 on the outer wall of the rotating rod 3 within the rotating groove 2 plays a crucial role. During rotation, the wedge-shaped card 26 is driven by the rotation of the disc. When the wedge-shaped card 26 disengages from the slot 14, the sliding plate 11 moves upward within the spring groove 10 under the action of the spring 13, and the extension rod 12 moves upward synchronously with the wedge-shaped card 26. As the disc 4 continues to rotate, when the wedge-shaped card 26 encounters the next slot 14, due to the elastic force of the spring 13, the wedge-shaped card 26 is embedded in the slot 14, achieving positioning and ensuring that the rotation angle of the disc 4 is accurate, so that the hollow groove 5 is accurately aligned with the injection port 6. When the hollow groove 5 is aligned with the selected injection port 6, the syringe pressure during injection causes the baffle 7 to disengage from the injection port 6 through the easily broken wire 8 for injection. If you need to change the injection position, rotate the disc 4 again and repeat the above rotation process including limiting and positioning to ensure accurate switching of injection position each time.

[0027] In this embodiment, the outer side wall of the arc-shaped card 1 is symmetrically fixedly connected with a fixing block 15. The front surface of the fixing block 15 is provided with a through-hole circular hole 16. The outer side wall of the left fixing block 15 is engaged with a left waist belt 17, and the outer side wall of the right fixing block 15 is engaged with a right waist belt 18. The front surfaces of the left waist belt 17 and the right waist belt 18 are provided with circular grooves 19. The circular grooves 19 and the interior of the adjacent circular holes 16 are engaged with pins 20. The lower surface of the right waist belt 18 is provided with a Velcro 21 on the left side, and the upper surface of the left waist belt 17 is provided with a sticker 22 on the right side. The Velcro 21 and the sticker 22 are bonded together. On the front surface of the disc 4, the outer side wall of the hollow groove 5 is fixedly connected with multiple writing boards 23. The inner side walls of the right waist belt 18 and the left waist belt 17 are both fixedly connected with soft pads 24.

[0028] First, place the arc-shaped card 1 in a suitable position on the patient's abdomen. Secure the left waist belt 17 to the outer wall of the left fixing block 15, and the right waist belt 18 to the outer wall of the right fixing block 15. Align the circular grooves 19 on the left and right waist belts 17 and 18 with the circular holes 16 on the fixing blocks 15, and insert the locking pins 20 to complete the initial fixation of the belts to the fixing blocks. Next, wrap the right waist belt 18 around the patient's body and connect it to the left waist belt 17. Adhere the Velcro 21 on the lower left side of the right waist belt 18 to the adhesive layer 22 on the upper right side of the left waist belt 17. This securely fixes the arc-shaped card 1 to the abdomen, and the inner padding 24 enhances wearing comfort. Then, rotate the disc 4, using the limiting block 9, wedge-shaped locking block 26, and locking groove 14 to position the cutout groove 5 aligned with the desired injection port 6. Before injection, relevant information, such as injection time and drug name, can be recorded on the writing board 23 on the disc 4. Finally, the injection is performed. The syringe pressure causes the baffle 7 to detach from the injection port 6 via the breakable wire 8, completing the subcutaneous injection. If it is necessary to change the injection site, repeat the positioning steps by rotating the disc 4.

[0029] In this embodiment, the outer side wall of the rotating rod 3 is symmetrically and fixedly connected with anti-slip blocks 25 on the outer side wall of the disc 4, and the front end of the rotating rod 3 is provided with a groove 26, and a plug 27 is engaged inside the groove 26.

[0030] After the arc-shaped card 1 is secured to the patient's abdomen with a belt, when the disc 4 needs to be rotated to align the slot 5 with the injection port 6, the anti-slip block 25 increases the friction between the hand and the rotating rod 3, making the rotation operation more stable and precise. During rotation, the limiting block 9, wedge-shaped card block 26, and card slot 14 work together for positioning. The design takes special care to avoid the enterostomy area to prevent unnecessary risks and discomfort to the patient. This design aims to provide a safe and convenient injection management tool for patients with enterostomy and diabetes. When removing the retainer 7, one of the injection ports 6 can be marked as the stoma observation port. The plug 27 originally inserted in the groove 26 can be pulled out to seal the observation port, achieving stoma protection.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
