Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a local injection aid for plantar warts. Background Technology

[0002] Plantar warts are a highly recurrent viral skin disease that occurs on the soles of the feet, often on the heels, the forefoot, or pressure points between the toes. Clinically, local injection therapy (such as bleomycin, fluorouracil, and interferon) is commonly used. Traditional injection methods often rely on the experience of healthcare professionals holding the syringe. Due to the thick stratum corneum of the sole and the indistinct borders of the warts, relying solely on manual injection can easily lead to needle placement errors. Existing universal injection positioning patches can effectively locate the warts and help healthcare professionals confirm the wart boundaries, thus effectively positioning the injection site. However, since local injections for plantar warts require injection into the dermis, injecting too shallowly will result in ineffective treatment, while injecting too deeply will damage tissue or cause pain. Universal injection positioning patches can only provide preliminary positioning and cannot adjust the injection depth, thus affecting injection efficiency and treatment effectiveness.

[0003] Therefore, the present invention provides a local injection aid for plantar warts to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a local injection aid for plantar warts. By setting an adjustment component, it can assist medical staff in adjusting the needle insertion depth of the syringe, which helps to ensure that the injection needle reaches the dermis layer, effectively improving the safety of the injection, increasing the injection efficiency and treatment effect. The above setting can solve the problem that the existing technology can only play a preliminary positioning role and cannot adjust the injection depth, thus affecting the injection efficiency and treatment effect.

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

[0006] A local injection aid for plantar warts includes an auxiliary frame, a connecting frame at the bottom of the auxiliary frame, a receiving ring at the bottom of the connecting frame, a plurality of abutment pieces circumferentially arranged at the bottom of the receiving ring, an adhesive ring at the bottom of the plurality of abutment pieces, a central block inside the auxiliary frame, a plurality of hinge frames circumferentially arranged between the inner wall of the auxiliary frame and the outer wall of the central block, and a plug-in tube snapped into each of the plurality of hinge frames; and an adjustment component for assisting medical personnel in adjusting the needle insertion depth of the syringe, the adjustment component being connected to the plug-in tube.

[0007] Optionally, the adjustment assembly includes a slider that slides on the inner wall of the plug-in cylinder, the slider having a placement groove, the inner wall of the placement groove having multiple limiting grooves circumferentially, the top of the slider having a limiting plate, the outer wall of the limiting plate having an adjustment block fixed thereon, the surface of the plug-in cylinder having multiple adjustment holes equidistantly arranged along the length direction, and the adjustment block engaging with one of the adjustment holes.

[0008] Optionally, the inner wall of the limiting plate is provided with a spring sheet, and the end of the spring sheet away from the slider is provided with a connecting part. The connecting part is made of a flexible material, and the end of the connecting part away from the spring sheet is connected to the inner wall of the limiting plate.

[0009] Optionally, the top of the limiting plate is provided with a hand-held part, and an arc-shaped part is provided between the limiting plate and the slider.

[0010] Optionally, the bottom of the slider is provided with a plurality of support brackets corresponding to the limiting groove, and a protective sleeve is provided at the bottom of the plurality of support brackets.

[0011] Optionally, the protective sleeve includes an abutment portion fixed to a plurality of the support brackets, and a plurality of protective portions and deformation portions are sequentially provided at the bottom of the abutment portion, wherein the cross section of the protective portion is tangent to the cross section of the steel needle of the syringe needle.

[0012] Optionally, a plurality of connecting shafts are provided circumferentially between the inner wall of the auxiliary frame and the outer wall of the central block, and each of the plurality of connecting shafts is fixed with a hinge seat, and the plurality of hinge seats are respectively hinged to the plurality of hinge frames.

[0013] Optionally, the hinge frame has a snap-fit ​​hole, and the surface of the plug tube has a snap-fit ​​block, with the snap-fit ​​hole engaging with the snap-fit ​​block.

[0014] Optionally, the auxiliary frame has a plug ring at the bottom and a slot at the top of the connecting frame, and the plug ring and the slot are plugged in and engaged.

[0015] Optionally, the connecting frame has a plurality of connecting blocks circumferentially arranged on its surface, and the auxiliary frame has connecting holes circumferentially arranged on its surface corresponding to the connecting blocks. The connecting blocks engage with the connecting holes to achieve detachable fixing of the auxiliary frame and the connecting frame.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting an adjustment component, medical staff can be assisted in adjusting the needle insertion depth of the syringe, which helps to ensure that the injection needle reaches the dermis. This avoids the situation where the treatment is ineffective due to injection that is too shallow, and also prevents the problem of tissue damage or pain caused by injection that is too deep. This effectively improves the safety of the injection, and increases the injection efficiency and treatment effect.

[0018] By incorporating auxiliary frames, connecting frames, receiving rings, and circumferentially arranged abutment pieces and adhesive rings, the device can stably conform to the plantar wart site, providing a stable support platform for medical personnel during injection operations. This effectively avoids the instability caused by holding the syringe, significantly improves the accuracy of the needle insertion position, and ensures that the injection operation can precisely target the wart area, thereby improving injection efficiency.

[0019] By setting sliders, limit plates, adjustment holes, adjustment blocks, and springs, medical staff can be assisted in adjusting the needle insertion depth of the syringe, which helps ensure that the injection needle reaches the dermis. The syringe can also be effectively limited during injection, which helps ensure the stability of the injection.

[0020] By setting up a protective sleeve, the syringe needle can be further supported, and the steel needle part of the needle can be constrained from multiple angles to ensure that the needle always advances stably in the predetermined direction, thus improving the stability of needle insertion. The protective part and the deformation part in the protective sleeve together form a continuous protective area on the needle surface, dispersing the force concentrated on a certain point of the needle to a larger area and a longer length, extending the area and point of force on the needle, effectively balancing the force on the needle, thereby preventing the needle from breaking due to excessive bending and improving the safety of treatment.

[0039] like Figures 1 to 9 As shown, an embodiment of the present invention provides a local injection aid for plantar warts, including an auxiliary frame 1, a connecting frame 3 at the bottom of the auxiliary frame 1, a receiving ring 7 at the bottom of the connecting frame 3, a plurality of abutment pieces 8 circumferentially arranged at the bottom of the receiving ring 7, an adhesive ring 9 at the bottom of the plurality of abutment pieces 8, a central block 10 inside the auxiliary frame 1, a plurality of hinge frames 13 circumferentially arranged between the inner wall of the auxiliary frame 1 and the outer wall of the central block 10, and a plug-in tube 15 snapped into each of the plurality of hinge frames 13; and an adjustment component, which is used to assist medical personnel in adjusting the needle insertion depth of the syringe, and the adjustment component is connected to the plug-in tube 15.

[0040] Specifically, the adhesive ring 9 is made of medical pressure-sensitive adhesive, and the abutment piece 8 is made of elastic material to compensate for the deformation of the top of the adhesive ring 9 when it is in contact with the patient's foot, so that the receiving ring 7 and its top auxiliary frame 1 can remain stable. The auxiliary frame 1 has a central block 10 inside, which serves as a connector. Multiple hinge frames 13 are circumferentially arranged between the inner wall of the auxiliary frame 1 and the outer wall of the central block 10. Each of the multiple hinge frames 13 has a plug tube 15 snapped into it. The adjustment component is used to assist medical staff in adjusting the needle insertion depth of the syringe. The adjustment component is connected to the plug tube 15.

[0041] During use, medical staff initially locate the plantar warts on the patient's foot. The auxiliary frame 1 and its bottom adhesive ring 9 are then attached to the affected area on the patient's foot. The adhesive ring 9 conforms to the contour of the patient's foot. With the connecting and compensating action of the abutment piece 8, the support ring 7 and auxiliary frame 1 remain stable, thus providing a stable support platform for the injection operation. This effectively avoids the instability caused by holding the syringe, significantly improving the accuracy of the needle insertion point and ensuring precise application of the injection to the wart area, thereby increasing injection efficiency. Medical staff then adjust the dosage according to the patient's foot location... The medical staff selects the corresponding hinge frame 13, manually adjusts the adjustment component to determine the needle depth, and ensures that the injection needle reaches the dermis. This avoids the situation where the treatment is ineffective due to injection that is too shallow, and also prevents the problem of tissue damage or pain caused by injection that is too deep. This effectively improves the safety of the injection, increases the injection efficiency and treatment effect. The syringe barrel is inserted into the plug tube 15 on the corresponding hinge frame 13. The adjustment component can also limit the syringe barrel and needle, thereby ensuring the stability of the medical staff during injection. The medical staff can then push the syringe to inject the drug into the affected area on the sole of the patient's foot.

[0042] In the above solution, by setting an adjustment component, medical staff can be assisted in adjusting the needle insertion depth of the syringe, which helps to ensure that the injection needle reaches the dermis. This avoids the situation where the treatment is ineffective due to injection that is too shallow, and also prevents the problem of tissue damage or pain caused by injection that is too deep. This effectively improves the safety of the injection, and increases the injection efficiency and treatment effect.

[0043] By setting up an auxiliary frame 1, a connecting frame 3, a receiving ring 7, and circumferentially arranged abutment pieces 8 and adhesive rings 9, it can stably fit the plantar wart site on the sole of the foot, providing a stable support platform for medical staff to perform injection operations. This effectively avoids the instability caused by holding the syringe, effectively improves the accuracy of the needle insertion position, ensures that the injection operation can accurately act on the wart area, and helps to improve injection efficiency.

[0044] It should be noted that the connector tube 15 is compatible with 1mL syringes.

[0045] As one implementation method in this embodiment, such as Figures 5 to 8 As shown, the adjustment assembly includes a slider 18 that slides on the inner wall of the insertion tube 15. The slider 18 has a placement groove 27, and the inner wall of the placement groove 27 has multiple limiting grooves 28 circumferentially arranged. A limiting plate 19 is provided at the top of the slider 18, and an adjustment block 20 is fixed to the outer wall of the limiting plate 19. Multiple adjustment holes 17 are equidistantly arranged along the length of the surface of the insertion tube 15. The adjustment block 20 engages with one adjustment hole 17. A handle 23 is provided at the top of the limiting plate 19, and an arc-shaped portion 22 is provided between the limiting plate 19 and the slider 18. It can be understood that there are two limiting plates 19 to facilitate the adjustment of the syringe insertion depth by medical personnel. Two rows of adjustment holes 17 are also provided corresponding to the limiting plates 19. When the syringe insertion depth needs to be adjusted, the medical personnel pinch the handles 23 corresponding to the tops of the two limiting plates 19 inwards with their fingers. At this time, the arc-shaped portion 22 deforms, causing the two limiting plates 19 to move closer together until the adjustment block 20 disengages from its corresponding adjustment hole 17, thereby releasing the syringe insertion depth. In addition to limiting the slider 18, pulling the limiting plate 19 can adjust the position of the slider 18 within the insertion tube 15. After adjustment, the arc-shaped part 22 resets, causing the adjusting block 20 to engage with the corresponding adjusting hole 17 after adjustment, thus limiting the slider 18 again. The adjustment of the slider 18 corresponds to the adjustment of the syringe insertion depth. When the slider 18 is away from the patient's foot, the syringe insertion depth is relatively shallow; when the slider 18 is close to the patient's foot, the syringe insertion depth is relatively deep. The interval between two adjacent adjusting holes 17 is 1 mm. The adjustment depth of the slider 18 is judged by the experience of medical personnel. When medical personnel insert the syringe into the insertion tube 15, the outline of the syringe needle matches the outline of the placement groove 27 in the slider 18. The number and outline of the protrusions on the surface of the syringe needle correspond to the limiting grooves 28, thereby limiting the syringe needle. The two limiting plates 19 can limit the position of the syringe barrel, ensuring the stability of the medical personnel during injection.

[0046] By setting up slider 18, limit plate 19, adjustment hole 17, adjustment block 20 and spring piece 21, medical staff can be assisted in adjusting the needle insertion depth of the syringe, which helps to ensure that the injection needle reaches the dermis. The syringe can also be effectively limited during injection, which helps to ensure the stability of the injection.

[0047] In this embodiment, as Figures 6 to 8As shown, the inner wall of the limiting plate 19 is provided with a spring piece 21. The end of the spring piece 21 away from the slider 18 is provided with a connecting part 24. The connecting part 24 is made of a flexible material, such as flexible rubber. The end of the connecting part 24 away from the spring piece 21 is connected to the inner wall of the limiting plate 19. The limiting plate 19 limits the syringe barrel through the spring piece 21. When the syringe is inserted into the insert tube 15, the spring piece 21 deforms and fits tightly against the syringe barrel, ensuring the stability of the injection process for medical personnel. The flexible connecting part 24 can play a buffering and guiding role when the spring piece 21 deforms. It will not interfere with the normal deformation of the spring piece 21, ensuring that the spring piece 21 can swing freely in and out around the axis of the insert tube 15 to achieve the limiting function of the syringe barrel. When the syringe is not inserted into the insert tube 15, the connecting part 24 can play a traction role on the top end of the spring piece 21 to avoid excessive deformation of the spring piece 21 and affect the limiting effect of the syringe barrel.

[0048] In this embodiment, as Figures 5 to 8 As shown, the bottom of the slider 18 is provided with multiple support brackets 25 corresponding to the limiting grooves 28. Each support bracket 25 has a protective sleeve 26 at its bottom. As mentioned earlier, the support brackets 25 also correspond to the protrusions on the surface of the syringe needle. The limiting grooves 28, through their adaptation to the protrusions on the needle surface, initially limit the range of motion of the needle. The support brackets 25, on this basis, support the needle from the bottom. The two work together to comprehensively reduce instability factors during injection, thus improving injection stability. The support brackets 25 provide initial support for the needle, while the protective sleeve 26 provides further guidance and support. Together, they provide solid support for the needle, dispersing the force exerted on the needle when inserted into the patient's foot, preventing excessive local force that could cause the needle to bend, ensuring smooth injection, effectively preventing damage to the tissues around the patient's foot due to needle bending, and reducing patient pain and complications.

[0049] By setting the protective sleeve 26, the syringe needle can be further supported, and the steel needle part of the needle can be constrained from multiple angles to ensure that the needle always moves stably in the predetermined direction, thus improving the stability of needle insertion. The protective part 31 and the deformation part 30 in the protective sleeve 26 together form a continuous protective area on the needle surface, dispersing the force concentrated on a certain point of the needle to a larger area and a longer length, extending the area and point of force on the needle, effectively balancing the force on the needle, thereby preventing the needle from breaking due to excessive bending and improving the safety of treatment.

[0050] It should be noted that the limiting plate 19, spring 21, slider 18, support bracket 25 and protective cover 26 are for single use only and need to be replaced after use, which effectively avoids the risk of cross-infection between different patients due to sharing parts.

[0051] In this embodiment, as Figures 5 to 9 As shown, the protective sleeve 26 includes an abutment portion 29 fixed to multiple support brackets 25. Multiple protective portions 31 and deformation portions 30 are sequentially arranged at the bottom of the abutment portion 29. The cross-section of the protective portion 31 is tangent to the cross-section of the steel needle of the syringe needle. The abutment portion 29 abuts against the surface of the needle, providing further support for the needle. The cross-section of the protective portion 31 is tangent to the cross-section of the steel needle, constraining the steel needle from multiple angles to ensure the needle always advances stably along a predetermined direction, improving the stability of needle insertion. The multiple protective portions 31 and deformation portions 30 together form a protective layer on the needle surface. The continuous protective area disperses the force concentrated on a single point of the needle onto a larger area and a longer length when the needle is inserted into the patient's sole due to the thick stratum corneum. This extends the area and point of force application on the needle. When the needle is subjected to excessive pressure and tends to bend, the deformation part 30 absorbs and disperses some of the external force through its own elastic deformation, reducing the stress on the steel needle and effectively balancing the force on the needle. This effectively prevents the needle from breaking due to excessive bending, thereby improving the safety of the treatment.

[0052] In this embodiment, as Figures 2 to 4 As shown, multiple connecting shafts 11 are circumferentially rotatable between the inner wall of the auxiliary frame 1 and the outer wall of the central block 10. Each connecting shaft 11 is fixed with a hinge seat 12. The multiple hinge seats 12 are respectively hinged to multiple hinge frames 13. It can be understood that the hinge seat 12 and the hinge frame 13 are ball joints. The connecting shaft 11 rotates circumferentially between the auxiliary frame 1 and the central block 10, allowing the syringe inserted into the insertion tube 15 to swing along the axis of the connecting shaft 11, so that the syringe can swing in the horizontal direction. The ball joint between the hinge seat 12 and the hinge frame 13 allows the syringe to rotate at multiple angles in three-dimensional space, which makes it easier for medical staff to flexibly adjust the angle of needle insertion, improving the flexibility and convenience of injection.

[0053] In this embodiment, as Figure 3 and Figure 4 As shown, the hinge frame 13 has a snap-fit ​​hole 14 inside, and the plug tube 15 has a snap-fit ​​block 16 on its surface. The snap-fit ​​hole 14 and the snap-fit ​​block 16 engage with each other. The hinge frame 13 and the plug tube 15 are connected through the snap-fit ​​engagement of the snap-fit ​​hole 14 and the snap-fit ​​block 16, so that the plug tube 15 can be flexibly disassembled. It can be used with the hinge frame 13 in different positions and applied to different foot acupoints, which improves the flexibility of the plug tube 15. At the same time, after use, it is easy to disassemble the plug tube 15 for thorough disinfection, which facilitates subsequent recycling and also facilitates the replacement and maintenance of the plug tube 15.

[0054] In this embodiment, as Figure 2 and Figure 3 As shown, the auxiliary frame 1 has a plug ring 2 at its bottom, and the connecting frame 3 has a slot 4 at its top. The plug ring 2 and the slot 4 are plugged in and engaged. Multiple connecting blocks 5 are circumferentially arranged on the surface of the connecting frame 3, and connecting holes 6 corresponding to the connecting blocks 5 are circumferentially arranged on the surface of the auxiliary frame 1. The connecting blocks 5 and the connecting holes 6 are snapped together, enabling the auxiliary frame 1 and the connecting frame 3 to be detachably fixed. The setting and method of the snap-fit ​​engagement of the connecting blocks 5 and the connecting holes 6 are disclosed in the prior art and will not be elaborated further here. The connecting frame 3, the receiving ring 7, the abutment piece 8, and the adhesive ring 9 mentioned above are all disposable parts and need to be replaced after each use, which can effectively avoid the sharing of parts between different patients. The insertion of the connector ring 2 and the slot 4 provides a quick and easy way to initially connect the connecting frame 3 and the auxiliary frame 1, thus reducing the risk of cross-infection. Medical staff only need to align the connector ring 2 at the bottom of the auxiliary frame 1 with the slot 4 at the top of the connecting frame 3 to complete the initial positioning and connection without complicated operations or the use of additional tools. The snap-fit ​​between the connecting block 5 and the connecting hole 6 further secures the connection between the auxiliary frame 1 and the connecting frame 3. When it is necessary to replace the disposable connecting frame 3, simply pry open the connecting block 5 to cancel the snap-fit ​​with the connecting hole 6 to remove the connecting frame 3 from the auxiliary frame 1, saving installation and disassembly time and improving work efficiency.

[0055] The working principle of the technical solution provided by this invention is as follows:

[0056] During use, medical staff initially confirm the location of the plantar warts on the patient's foot. They then attach the auxiliary frame 1 and its bottom adhesive ring 9 to the affected area on the patient's foot, ensuring the adhesive ring 9 conforms to the contour of the patient's foot. With the connecting and compensating action of the abutment piece 8, the receiving ring 7 and the auxiliary frame 1 remain stable, providing a stable support platform for the medical staff's injection operation. Based on the location of the affected area on the patient's foot, the medical staff selects the corresponding hinge frame 13. By pinching the corresponding hand-held part 23 at the top of the two limiting plates 19 inwards with their fingers, the curved part 22 deforms, causing the two limiting plates 19 to move closer together until the adjusting block 20 disengages from its corresponding adjusting hole 17, thereby releasing the limiting position of the slider 18. Pulling the limiting plate 19 adjusts the position of the slider 18 within the insertion tube 15. Based on the medical staff's experience, they judge the distance between the slider 18 and the patient's foot to assist in controlling the depth of needle insertion. After adjustment, the curved part 22 returns to its original position, allowing the adjusting block 20 to... The 0 engages with the corresponding adjustment hole 17 after adjustment, further limiting the slider 18 and completing the adjustment of the needle insertion depth to ensure that the injection needle reaches the dermis. Medical staff can adjust the needle insertion angle by swinging the insertion tube 15. After confirming the needle insertion position, the medical staff inserts the syringe containing the therapeutic drug into the insertion tube 15 on the corresponding hinge frame 13. The outline of the syringe needle matches the outline of the placement groove 27 in the slider 18. The number and outline of the protrusions on the surface of the syringe needle correspond to the limiting grooves 28, thereby limiting the syringe needle. The limiting grooves 28 initially limit the range of motion of the needle by matching the protrusions on the surface of the needle. The support frame 25 supports the needle from the bottom on this basis. The two work together to ensure the stability of the needle during the injection process. The support frame 25 provides initial support for the needle, and the protective sleeve 26 provides further guidance and support for the needle. The two work together to provide solid support for the needle.When the needle is inserted into the patient's sole, the thick stratum corneum of the sole results in high local pressure upon needle insertion. Multiple protective parts 31 and deformable parts 30 together form a continuous protective area on the needle surface, dispersing the force concentrated at a single point on the needle over a larger area and longer length. This extends the area and point of force application on the needle, effectively balancing the force on the needle and thus preventing breakage due to excessive bending. After treatment, medical personnel first withdraw the syringe, then pinch the corresponding handle 23 at the top of the two limiting plates 19 inwards with their fingers. The arc-shaped part 22 deforms, causing... The two limiting plates 19 are brought closer together until the adjusting block 20 disengages from the corresponding adjusting hole 17, thereby releasing the limiting position of the slider 18. The limiting plates 19, spring 21, slider 18, support frame 25 and protective sleeve 26 are removed. Then, the adhesive ring 9 is peeled off from the patient's foot and the connecting block 5 is pried to cancel the snap-fit ​​with the connecting hole 6. The connecting frame 3 is removed from the auxiliary frame 1. The parts that come into direct contact with the syringe and the patient's foot are discarded as required. Then, the insertion tube 15 is removed from the hinge frame 13 and disinfected together with the auxiliary frame 1 for subsequent reuse.
