[0001] The utility model belongs to the technical field of grass carp breeding management, and particularly relates to a subcutaneous implantable drug delivery device for grass carp. Background Technique
[0002] Grass carp, belonging to the Cyprinidae family, is the main object of freshwater fish farming in China and is distributed in major water systems in China. It has delicious meat. In the breeding of grass carp, grass carp may suffer from erythroderma during a certain period. In severe cases, the fish skin will fester and necrosis, and even death may occur.
[0003] In order to treat the fish skin, it is necessary to inject the liquid medicine into the fish skin by using a subcutaneous implanting syringe. When the existing implanting syringe is in use, due to technical problems of farmers, it is inconvenient to control the amount of medicine injected, and the amount of liquid medicine may be too much or too little, thus increasing the inconvenience of injection. For this reason, we propose a subcutaneous implantable drug delivery device for grass carp to solve the above-mentioned deficiencies. Content of the Utility Model
[0004] The purpose of the utility model is to provide a subcutaneous implantable drug delivery device for grass carp, which has the purpose of facilitating the control of the amount and thus improving the convenience of injection, so as to solve the above-mentioned background technical problems.
[0005] The technical solution for the utility model to solve the above technical problems is as follows: A subcutaneous implantable drug delivery device for grass carp includes a tube body. One end of the tube body is integrally communicated with a connecting tube, and the other end of the tube body is integrally communicated with a tube plate. The inner surface of the tube plate is integrally and fixedly connected with a threaded sleeve, and the inner surface of the threaded sleeve is threadedly connected with a threaded cylinder. Chutes are respectively arranged on the inner surface of the threaded cylinder at positions symmetrical to the axis point of the threaded cylinder. A push rod is slidably arranged through the inner surface of the threaded cylinder. A slider is fixedly connected to the outer surface of the push rod, and the surface of the slider is slidably adapted to the inner surface of the chute. The end of the push rod passing through the tube body is rotatably connected with a connecting plate through a bearing seat. A rubber ring is bonded to the surface of the connecting plate, and the outer surface of the rubber ring is slidably attached to the inner surface of the tube body. The end surface of the connecting tube away from the tube body is detachably connected with a syringe. A limit bolt is threadedly connected to the top surface of the threaded cylinder. The limit bolt penetrates through the inside of the threaded cylinder and is located at the left end of the initial position of the upper slider and is in mutual contact.
[0006] Preferably, the port of the connecting tube away from the tube body is threadedly connected with the syringe. A liquid injection tube can be communicated with the top of the syringe, and a valve is movably connected to the port of the liquid injection tube.
[0007] Preferably, a handle body for rotating the push rod is fixedly connected to the end surface of the push rod outside the tube body, and the surface of the handle body is designed with anti-slip lines.
[0008] Preferably, the left end of the sliding groove penetrates through the left end face of the threaded cylinder.
[0009] Preferably, the tube body is designed to be transparent, and scale lines are provided on the surface of the tube body.
[0010] 1. The beneficial effects of the present utility model are as follows: When using the present utility model, one hand holds the tube body, and the other hand rotates the push rod. The rotation of the push rod drives the rotation of the slider through the rotation of the bearing seat. Since the slider is on the inner surface of the sliding groove, the sliding groove plays a role in limiting the position, thereby driving the threaded cylinder to rotate in a threaded manner on the inner surface of the threaded sleeve. Then, the threaded cylinder is pushed into the tube body. Then, according to the needs, observe the scale lines on the surface of the threaded cylinder. Due to the limitation of the limit bolt, the initial position of the slider always remains unchanged, so that the position of the rubber ring corresponds to the required scale line, thereby limiting the amount of liquid sucked into the syringe needle tube, facilitating the control of the amount, and further improving the convenience of liquid injection.
[0011] 2. By providing a threaded connection between the connecting tube and the syringe needle tube in the present utility model, it is convenient to replace the type of syringe needle tube. At the same time, through the liquid injection tube, external conduits can be connected according to needs, and the opening or closing is achieved through the valve, and the flow rate is controlled simultaneously.
[0012] 3. By providing that the left end of the sliding groove penetrates through the left end face of the threaded cylinder in the present utility model, the rubber ring is pushed to the leftmost end of the tube body.
[0013] 4. By providing that the tube body is designed to be transparent and scale lines are provided on the surface of the tube body in the present utility model, it is convenient for the user to observe and rotate the push rod at any time to change the position where the threaded cylinder is pushed.

[0020] In the following, embodiments of the grass carp subcutaneous implantable drug delivery device of the present utility model will be described with reference to the accompanying drawings.
[0021] Embodiment 1:
[0022] Figures 1-3 A grass carp subcutaneous implantable drug delivery device showing an embodiment of the present utility model includes a tube body 1. The tube body 1 is designed to be transparent, and scale lines are provided on the surface of the tube body 1. By setting the tube body 1 to be transparent and having scale lines on its surface, it is convenient for users to observe and rotate the push rod 8 at any time to change the position where the threaded cylinder 5 advances. One end of the tube body 1 is integrally connected to a connecting tube 2, and the other end of the tube body 1 is integrally connected to a tube plate 3. An inner surface of the tube plate 3 is integrally and fixedly connected to a threaded sleeve 4. The inner surface of the threaded sleeve 4 is threadedly connected to a threaded cylinder 5. Chute grooves 6 are provided at positions on the inner surface of the threaded cylinder 5 that are symmetric with respect to the axis point of the threaded cylinder 5. The left end of the chute groove 6 penetrates through the left end face of the threaded cylinder 5. By setting the left end of the chute groove 6 to penetrate through the left end face of the threaded cylinder 5, the rubber ring 11 is pushed to the leftmost end of the tube body 1. A push rod 8 is slidably arranged through the inner surface of the threaded cylinder 5. An end face of the push rod 8 penetrating outside the tube body 1 is fixedly connected to a handle body 15 for rotating the push rod 8. The surface of the handle body 15 is designed with anti-slip lines. An outer surface of the push rod 8 is fixedly connected to a slider 7. The surface of the slider 7 is slidably adapted to the inner surface of the chute groove 6. The end of the push rod 8 penetrating through the tube body 1 is rotatably connected to a connecting plate 10 through a bearing seat 9. A rubber ring 11 is bonded to the surface of the connecting plate 10. The outer surface of the rubber ring 11 is in sliding fit with the inner surface of the tube body 1. The end face of the connecting tube 2 away from the tube body 1 is detachably connected to a syringe needle 12. A limit bolt 16 is threadedly connected to the top surface of the threaded cylinder 5. The limit bolt 16 penetrates through the inside of the threaded cylinder 5 and is located at the left end of the initial position of the upper slider 7 and is in mutual contact. The user holds the tube body 1 with one hand and rotates the push rod 8 with the other hand, so that the push rod 8 rotates through the rotation of the bearing seat 9, thereby driving the slider 7 to rotate. Since the slider 7 is on the inner surface of the chute groove 6, the chute groove 6 plays a role in limiting, thereby driving the threaded cylinder 5 to rotate threadedly on the inner surface of the threaded sleeve 4, and further advancing the threaded cylinder 5 into the tube body 1. Then, observe the scale lines on the surface of the threaded cylinder 5 according to the needs. Since the limit of the limit bolt 16 always keeps the initial position of the slider 7 unchanged, the position of the rubber ring 11 can be corresponding to the required scale line, so as to limit the amount of liquid inhaled into the tube, thereby facilitating the control of the amount and further improving the convenience of liquid injection.
[0023] Embodiment 2:
[0024] Figures 1-3The subcutaneous implantable drug delivery device for grass carp showing an embodiment of the present utility model includes a tube body 1. One end of the tube body 1 is integrally connected with a connecting tube 2, and the other end of the tube body 1 is integrally connected with a tube plate 3. An inner surface of the tube plate 3 is integrally and fixedly connected with a threaded sleeve 4. An inner surface of the threaded sleeve 4 is threadedly connected with a threaded cylinder 5. Chutes 6 are provided at positions on the inner surface of the threaded cylinder 5 that are symmetric with respect to the axis point of the threaded cylinder 5. A push rod 8 is slidably disposed through the inner surface of the threaded cylinder 5. An outer surface of the push rod 8 is fixedly connected with a slider 7. A surface of the slider 7 is slidably engaged with an inner surface of the chute 6. The push rod 8 passes through the end of the tube body 1 and is rotatably connected with a connecting plate 10 through a bearing seat 9. A rubber ring 11 is bonded to a surface of the connecting plate 10. An outer surface of the rubber ring 11 is slidably fitted with an inner surface of the tube body 1. A syringe 12 is detachably connected to an end face of the connecting tube 2 away from the tube body 1. A threaded connection is provided between a port of the connecting tube 2 away from the tube body 1 and the syringe 12. A liquid injection tube 13 can be connected to a top of the syringe 12. A valve 14 is movably connected to a port of the liquid injection tube 13. By providing a threaded connection between the connecting tube 2 and the syringe 12, it is convenient to replace the type of the syringe 12. At the same time, through the liquid injection tube 13, an external catheter can be connected as needed, and the opening or closing is achieved through the valve 14, and the flow rate is controlled at the same time. A limit bolt 16 is threadedly connected to a top surface of the threaded cylinder 5. The limit bolt 16 passes through the inside of the threaded cylinder 5 and is located at the left end of the initial position of the upper slider 7 and is in mutual contact.
[0025] When this embodiment needs to be used, only the position of the tube body 1 needs to be tilted, and other required liquid medicines are injected into the fish skin through the liquid injection tube 13.
[0026] Working principle: When the present utility model is in use, a user or a breeder holds the tube body 1 with one hand and rotates the push rod 8 with the other hand, so that the push rod 8 drives the slider 7 to rotate through the rotation of the bearing seat 9. Since the slider 7 is on the inner surface of the chute 6, the chute 6 plays a role in limiting, thereby driving the threaded cylinder 5 to rotate threadedly on the inner surface of the threaded sleeve 4, and then pushing the threaded cylinder 5 into the tube body 1. Then, according to the need, observe the scale line on the surface of the threaded cylinder 5. Since the limit of the limit bolt 16 always keeps the initial position of the slider 7 unchanged, the position of the rubber ring 11 can be corresponding to the required scale line, so as to control the amount by limiting the amount of liquid sucked into the tube. After controlling the suction liquid capacity, the limit bolt 16 can be loosened, so that the push rod 8 slides on the inner surface of the chute 6 through the slider 7, thereby driving the rubber ring 11 to be pushed to the leftmost end of the inner cavity of the tube body 1. Finally, the liquid medicine is sucked through the syringe 12, and only the push rod 8 needs to be pulled to the position where it cannot be pulled anymore.
[0027] Finally, it is directly injected into the fish skin through the syringe 12, which facilitates the control of the amount, thereby improving the injection convenience and avoiding the situation of too much or too little injection amount.
