Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a visual multifunctional internal hemorrhoid injection therapy device. Background Technology

[0002] Internal hemorrhoids are varicose veins that form above the dentate line at the end of the rectum. Sclerotherapy is a commonly used treatment for internal hemorrhoids. This treatment is simple, effective, and inexpensive, and does not require hospitalization. It is more in line with modern people's concepts of treating diseases and pursuing health, and has become one of the main methods for the clinical treatment of grade I to III internal hemorrhoids.

[0003] Internal hemorrhoids are the most common anorectal disease. They commonly occur at the 3, 7, and 11 o'clock positions in the lithotomy position, also known as the "mother hemorrhoid area," while those occurring in other areas are called "daughter hemorrhoids." The conventional treatment for internal hemorrhoids is syringe-based medication administration. However, current syringes for internal hemorrhoids are ineffective because the amount of medication injected into each hemorrhoid varies, making it difficult to accurately control the dosage and locate the pathological site for precise medication application. Therefore, we propose a visual, multifunctional internal hemorrhoid injection therapy device to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a visual multifunctional internal hemorrhoid injection therapy device to solve the problems mentioned in the background art, such as the difficulty in accurately controlling the dosage when injecting multiple hemorrhoids because the amount of medication injected at each point is different, and the inability to reasonably locate the pathological location for medication application, resulting in poor practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a visual multifunctional internal hemorrhoid injection treatment device, comprising an outer tube of a syringe, a base lug fixedly connected to the outer side of the outer tube of the syringe, a push rod movably connected inside the base lug, a pressing block fixedly connected to the upper end of the push rod, a drug delivery plug fixedly connected to the lower end of the push rod, an injection needle fixedly connected to the lower end of the outer tube of the syringe, a metering component provided at the top of the outer tube of the syringe, and an auxiliary component provided on the outer side of the outer tube of the syringe; The quantitative component includes a fixing plate, a first external thread, a guide plate, and a limiting ring. The top of the syringe outer tube is provided with two sets of fixing plates, and the outer surface of the fixing plate is provided with a first external thread. The outer side of the pressing block is provided with two sets of guide plates, and the outer side of the fixing plate is provided with a limiting ring.

[0006] Preferably, the auxiliary component includes a fixed ring, a movable ring, and a protective pad. The fixed ring is fixedly connected to the bottom outer side of the syringe outer tube. A miniature camera and an LED light are installed inside the fixed ring facing the injection needle. The movable ring is movably connected to the outer side of the syringe outer tube. A protective pad is provided between the fixed ring and the movable ring. The protective pad is movably fitted onto the surface of the syringe outer tube, and its upper and lower ends are connected to the fixed ring and the movable ring, respectively.

[0007] Preferably, the two sets of fixing plates are fixedly connected to the top of the syringe outer tube, the first external thread is formed on the outer surface of the two sets of fixing plates, the two sets of guide plates are respectively fixedly connected to both sides of the pressing block, the distance between the two sets of fixing plates is adapted to the guide plates, and the inner wall of the limiting ring is provided with a thread adapted to the first external thread.

[0008] Preferably, the auxiliary component further includes a second external thread and a positioning ring. The surface of the syringe outer tube is provided with a second external thread, and the outer thread of the second external thread is connected to a positioning ring, which is located above the movable ring.

[0009] Preferably, two sets of first sliders are fixedly connected to both sides of the pressing block, and a first groove is provided at the center of the inner wall of the fixing plate, the inner diameter of the first groove being adapted to the first slider.

[0010] Preferably, the inner wall of the movable ring is fixedly connected with two sets of second sliders, and the outer surface of the syringe outer tube is provided with two sets of second sliding grooves, the inner diameter of the second sliding grooves being adapted to the second sliders.

[0011] Preferably, the outer surface of the fixing plate is connected with scale lines, and the fixing plate is made of transparent plastic.

[0012] Preferably, both the limiting ring and the positioning ring are connected to rubber pads, and the surface of the rubber pads is provided with wavy anti-slip textures with a depth of two millimeters.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the setting of a quantitative component, rotates the limiting ring to a designated position, so that when the pressing block drives the guide plate to descend, it contacts the limiting ring, thereby restricting the descent position of the pressing block and achieving the effect of quantitative injection. Appropriate injection solution is injected according to different hemorrhoids, which greatly reduces the difficulty of injection, is simple to operate, convenient to use, and simplifies the operation process.

[0014] 2. This invention, through the setting of auxiliary components, moves the movable ring toward the fixed ring, compresses the protective pad, causes the protective pad to deform and unfold outward to contact the patient's skin, and positions the outer tube of the syringe. Using this position as a fulcrum, the direction of the injection needle is adjusted to find the internal hemorrhoid site for targeted drug delivery, which is beneficial for the drug to directly act on the wound site. At the same time, the unfolding of the protective pad has the function of preventing dirt from flowing down. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-6 An embodiment of the present invention provides a visual multifunctional internal hemorrhoid injection treatment device, including a syringe outer tube 1, a base lug 2 fixedly connected to the outside of the syringe outer tube 1, a push rod 3 movably connected inside the base lug 2, a pressing block 4 fixedly connected to the upper end of the push rod 3, a drug delivery plug 5 fixedly connected to the lower end of the push rod 3, an injection needle 6 fixedly connected to the lower end of the syringe outer tube 1, a metering component 7 provided at the top of the syringe outer tube 1, and an auxiliary component 8 provided on the outside of the syringe outer tube 1. The quantitative component 7 includes a fixing plate 701, a first external thread 702, a guide plate 703 and a limiting ring 704. Two sets of fixing plates 701 are provided on the top of the syringe outer tube 1. The outer surface of the fixing plate 701 is provided with the first external thread 702. Two sets of guide plates 703 are provided on the outer side of the pressing block 4. The limiting ring 704 is provided on the outer side of the fixing plate 701. This device, through the setting of quantitative component 7 and auxiliary component 8, solves the problem that when injecting multiple hemorrhoids, it is difficult to accurately control the amount of medication injected at each point of hemorrhoid, and it is also difficult to reasonably locate the pathological location for medication, resulting in poor practicality.

[0020] Furthermore, the auxiliary component 8 includes a fixed ring 801, a movable ring 802, and a protective pad 803. A fixed ring 801 is fixedly connected to the bottom outer side of the syringe outer tube 1. Depending on the usage, a miniature camera and LED light are installed inside the fixed ring 801 facing the injection needle 6 for easy observation of the internal situation. A connecting wire is set along the outer surface of the syringe outer tube 1 for connection to external devices. A movable ring 802 is movably connected to the outer side of the syringe outer tube 1. A protective pad 803 is provided between the fixed ring 801 and the movable ring 802. The protective pad 803 is made of transparent silicone to prevent damage when in contact with the patient's skin. The protective pad 803 is movably fitted onto the surface of the syringe outer tube 1, and its upper and lower ends are connected to the fixed ring 801 and the movable ring 802, respectively. Figure 3 As shown, this structure is used to move the protective pad 803 towards the fixed ring 801 by pushing the movable ring 802. Due to the characteristics of the protective pad 803, the protective pad 803 deforms and unfolds outward to contact the patient's skin, positioning the syringe outer tube 1. At the same time, it can stably adjust the orientation of the injection needle 6 to facilitate injection. During injection, the protective pad 803 can prevent tissue contaminants from flowing down.

[0021] Furthermore, two sets of fixing plates 701 are fixedly connected to the top of the syringe outer tube 1. A first external thread 702 is formed on the outer surface of the two sets of fixing plates 701. Two sets of guide plates 703 are respectively fixedly connected to both sides of the pressing block 4. The distance between the two sets of fixing plates 701 is adapted to the guide plates 703. The width between the two sets of fixing plates 701 can accommodate a thumb, and can also be adjusted according to actual use. The inner wall of the limiting ring 704 has a thread adapted to the first external thread 702. For example... Figure 2 As shown, this structure is used to reach a designated position by rotating the limiting ring 704, and then pressing the pressing block 4 to drive the guide plate 703 and the drug delivery plug 5 to move along the gap between the fixed plate 701, so that the guide plate 703 contacts the surface of the limiting ring 704 to limit the pressing block 4, thereby controlling the appropriate amount of medicine to be discharged from the injection needle 6, and injecting appropriate injection solution according to different hemorrhoids.

[0022] Furthermore, the auxiliary component 8 also includes a second external thread 804 and a positioning ring 805. The surface of the syringe outer tube 1 is provided with the second external thread 804, and the outer thread of the second external thread 804 is threaded with the positioning ring 805, which is located above the movable ring 802. Figure 3 As shown, this structure is used to rotate the positioning ring 805 by means of a thread on the inner wall of the positioning ring 805 that is compatible with the second external thread 804, thereby driving the movable ring 802 to move and positioning the movable ring 802.

[0023] Furthermore, two sets of first sliders 9 are fixedly connected to both sides of the pressing block 4, and a first groove 10 is provided at the center of the inner wall of the fixing plate 701. The inner diameter of the first groove 10 is adapted to the first slider 9. Figure 5 As shown, this structure is used to drive the first slider 9 to move along the first slide groove 10 when the pressing block 4 is pressed down, so that the pressing block 4 moves stably within the fixed plate 701.

[0024] Furthermore, two sets of second sliders 11 are fixedly connected to the inner wall of the movable ring 802, and two sets of second sliding grooves 12 are formed on the outer surface of the syringe outer tube 1, the inner diameter of the second sliding grooves 12 being adapted to the second sliders 11. Figure 6 As shown, this structure is used to move along the second slide groove 12 with the help of the second slider 11 when the movable ring 802 moves downward, thereby improving the stability of the movable ring 802.

[0025] Furthermore, the outer surface of the fixing plate 701 is connected to scale lines 705, and the fixing plate 701 is made of transparent plastic. For example... Figure 2 As shown, this structure is used to accurately inject medication by locating the position of the limiting ring 704 according to the dosage through the scale line 705 on the surface of the fixing plate 701.

[0026] Furthermore, both the limiting ring 704 and the positioning ring 805 are fitted with rubber pads, and the surfaces of the rubber pads are provided with wavy anti-slip textures with a depth of two millimeters to prevent the limiting ring 704 and the positioning ring 805 from slipping off the hand during rotation. Figure 4 As shown, this structure utilizes the cushioning and anti-slip properties of rubber. Its anti-slip texture enhances its anti-slip effect, and the two-millimeter depth ensures that the anti-slip texture still provides an anti-slip effect even after a certain degree of wear.

[0027] Working principle: Before use, such as Figure 1 and Figure 2 As shown, first pull the pressing block 4 to drive the push rod 3 and the drug delivery plug 5 to the top of the syringe outer tube 1, so that the drug is drawn into the syringe outer tube 1. Then, rotate the limiting ring 704 to the designated position along the first external thread 702 according to the scale line 705 on the surface of the fixing plate 701. Then, slowly insert the front end of the syringe outer tube 1 into the intestinal lumen, leaving the other end outside the body. Figure 3 and Figure 6 As shown, rotating the positioning ring 805 moves it along the second external thread 804 on the surface of the syringe outer tube 1 towards the fixed ring 801. With the aid of the second slider 11, it moves along the second slide groove 12, pushing the movable ring 802 to move the protective pad 803 towards the fixed ring 801. Due to the characteristics of the protective pad 803, it deforms and unfolds outwards to contact the patient's skin, positioning the syringe outer tube 1. Simultaneously, it can stably adjust the orientation of the injection needle 6, facilitating injection. During injection, if... Figure 4 As shown, the protective gasket 803 can prevent tissue contamination from flowing downwards, such as... Figure 2 and Figure 5 As shown, pressing the pressing block 4 drives the guide plate 703 and the drug delivery plug 5. The guide plate 703 moves along the gap between the fixed plates 701, and at the same time drives the first slider 9 to move along the first slide groove 10, so that the guide plate 703 contacts the surface of the limiting ring 704, limiting the pressing block 4, thereby controlling the appropriate amount of medicine to be discharged from the injection needle 6. According to different hemorrhoids, appropriate injection solution is injected. The above is the entire working principle of the present invention.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
