Description

Technical Field

[0001] This utility model relates to the field of flushing needle technology, and in particular to an expansion flushing needle. Background Technology

[0002] For cleaning abscesses in the skin of large animals such as elephants, the traditional syringes currently used have significant limitations. The small diameter of the discharge port on a conventional syringe, while capable of injecting medication, fails to create sufficient flow velocity to effectively remove necrotic tissue during flushing. Furthermore, the non-adjustable outlet structure of traditional syringes prevents flushed necrotic tissue from easily entering the syringe for extraction, resulting in low cleaning efficiency and a risk of secondary contamination.

[0003] Due to the unique structure of elephant skin, its abscesses are deep and the necrotic tissue inside is difficult to remove. The cleaning process can easily cause repeated infections or wound deterioration. Therefore, it is particularly important to develop a special instrument that can efficiently flush the abscesses and smoothly extract the necrotic tissue. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an expandable flushing syringe to solve the problem that the outlet size of traditional syringes is fixed and cannot be flexibly adjusted.

[0005] To achieve the above objectives, this utility model provides an expanding flushing needle, including a discharge port. Multiple fixing rods are fixedly installed on the inner wall of the discharge port. Multiple limiting shafts are fixedly installed on the fixing rods. A first transmission rod is rotatably connected to the limiting shaft. The other end of the first transmission rod is rotatably connected to a fixing block via the limiting shaft. The fixing block has a receiving groove that cooperates with the first transmission rod. A movable rod is fixedly sleeved in the middle of the fixing block. A second transmission rod is rotatably connected to the fixed block at a position away from the discharge port on the movable rod. The other end of the second transmission rod is rotatably connected to the fixing rod via the limiting shaft.

[0006] Preferably, a housing is fixedly connected to one side of the discharge port, and a rubber plug is slidably disposed inside the housing. The side of the rubber plug near the discharge port is fixed to the movable rod.

[0007] Preferably, a push-pull rod is fixedly connected to the side of the rubber stopper away from the discharge port, and a push-pull plate is fixedly connected to the other end of the push-pull rod. A baffle is fixedly provided on the outer wall of the outer shell near the push-pull plate.

[0008] Preferably, the diameter of the rubber stopper is the same as the inner wall diameter of the outer shell.

[0009] Preferably, the push-pull plate is provided with multiple grooves of the same depth.

[0010] Preferably, the length of the second transmission rod is longer than the length of the first transmission rod.

[0011] Preferably, the discharge port is made of a rubber material with excellent deformation properties.

[0012] Preferably, the push-pull rod is a part with two discs near the rubber stopper and a cross-shaped main body.

[0013] The beneficial effects of this utility model are:

[0014] 1. This dilatation flushing syringe has a discharge port made of rubber with excellent deformation properties. It can contract when pushing the liquid medicine to increase the flow rate and enhance the flushing effect; it can also expand when aspirating necrotic tissue to facilitate the smooth entry of tissue into the syringe, thus meeting the cleaning needs of abscess cavities and significantly improving cleaning efficiency.

[0015] 2. This dilating flushing needle, through the combined design of a fixed rod, a limiting shaft, a first transmission rod, and a second transmission rod, forms a multi-point support structure, which effectively disperses the force during operation and prevents the device from failing due to uneven force during expansion or contraction. Combined with the precise design of the receiving groove and the transmission rod, it ensures the smoothness and controllability of the expansion and contraction actions, thereby improving the reliability of the equipment and the stability of operation.

[0025] like Figures 1 to 4As shown, an expanding flushing needle includes an outlet 2. Multiple fixing rods 8 are fixedly installed on the inner wall of the outlet 2. Multiple limiting shafts 6 are fixedly installed on the fixing rods 8. A first transmission rod 11 is rotatably connected to the limiting shafts 6. The other end of the first transmission rod 11 is rotatably connected to a fixing block 9 via the limiting shafts 6. The fixing block 9 has a receiving groove 12 that cooperates with the first transmission rod 11. A movable rod 10 is fixedly sleeved in the middle of the fixing block 9. A second transmission rod 13 is rotatably connected to the fixed block 9 on the movable rod 10 away from the outlet of the outlet 2. The other end of the second transmission rod 13 is rotatably connected to the fixing rod 8 via the limiting shafts 6. The length of the second transmission rod 13 is longer than the length of the first transmission rod 11. The outlet 2 is made of a rubber material with excellent deformation properties. The use of a rubber material with excellent deformation properties allows the outlet 2 to expand or contract according to needs, improving adaptability and facilitating adjustment of the outlet size during flushing to adapt to different operational requirements. When flushing is required, the outlet 2 expands or contracts as needed. The discharge port 2 contracts, increasing the flow rate of the medicine to flush the pus cavities inside the elephant's skin. When withdrawing, the diameter of discharge port 2 expands, allowing necrotic tissue to be extracted from the pus cavities. A stable multi-point support and transmission structure is formed by the combination of the fixed rod 8, the limiting shaft 6, the first transmission rod 11, and the second transmission rod 13. The design effectively disperses the force applied during operation, improving the stability of the equipment. The difference in length between the first transmission rod 11 and the second transmission rod 13, in conjunction with the movable rod 10, realizes the expansion and contraction of discharge port 2. The flushing range can be adjusted according to actual needs to improve flushing efficiency. At the same time, the slightly longer second transmission rod 13 ensures that the entire expansion structure will not overturn excessively when pushing the medicine, thus affecting the expansion and contraction functions. The receiving groove 12 on the fixed block 9 works in conjunction with the transmission rod to ensure the stability and accuracy of the transmission structure, making the expansion and contraction actions smoother and more controllable.

[0026] Furthermore, such as Figure 1 as well as Figure 2As shown, a housing 1 is fixedly connected to one side of the discharge port 2. A rubber plug 7 is slidably installed inside the housing 1. The side of the rubber plug 7 near the discharge port 2 is fixed to the movable rod 10. The diameter of the rubber plug 7 is the same as the inner wall diameter of the housing 1. A push-pull rod 4 is fixedly connected to the side of the rubber plug 7 away from the discharge port 2. A push-pull plate 5 is fixedly connected to the other end of the push-pull rod 4. A baffle 3 is fixedly installed on the outer wall of the housing 1 near the push-pull plate 5. The push-pull rod 4 is a part with two discs near the rubber plug 7 and a cross-shaped main body. Multiple grooves of the same depth are fixedly opened on the push-pull plate 5. The rubber plug 7 has the same diameter as the inner wall diameter of the housing 1, ensuring sealing during sliding, preventing flushing fluid leakage, and improving the use of the equipment. For efficiency and reliability, the push-pull rod 4 is fixedly connected to the rubber plug 7 and the push-pull plate 5. The movement of the rubber plug 7 can be flexibly controlled by manually pushing and pulling the plate 5. The operation is simple, intuitive and easy to use. The cross-shaped main body increases the stability of the push-pull rod 4 and effectively prevents deviation during sliding. At the same time, the two discs near the side of the rubber plug 7 further enhance the uniformity and accuracy of the push-pull force transmission. A baffle 3 is fixedly installed on the outer wall of the outer shell 1 near the push-pull plate 5 to prevent the push-pull plate 5 from excessive displacement during operation, protect the integrity of the internal structure, and improve the overall stability and durability of the equipment. The rubber plug 7 is fixedly connected to the movable rod 10 to ensure that the movement of the rubber plug 7 is consistent with the movement of the movable rod 10, so as to achieve smooth and efficient operation.

[0027] Workflow:

[0028] When it is necessary to flush the abscess cavity of an elephant's skin, firstly, an appropriate amount of medicine is drawn into the syringe and contained inside the outer shell 1. Then, the syringe is aligned with the abscess cavity opening, and the outlet 2 is inserted into the abscess cavity. The push-pull plate 5 drives the push-pull rod 4 to inject the medicine into the abscess cavity through the outlet 2. During the process of pushing the medicine, the rubber stopper 7 drives the movable rod 10 to move towards the outlet, thereby causing the fixed block 9 to move. Then, the first transmission rod 11 drives the fixed rod 8 to contract inward, thereby reducing the diameter of the outlet 2. Under the same force, the flow rate will increase at the smaller diameter position, so that the medicine can obtain a greater flow rate to flush the inside of the abscess cavity, causing the necrotic tissue to fall off. After all the medicine has been pushed, the push-pull plate 5 is pulled in the opposite direction, causing the rubber stopper 7 to drive the movable rod 10 to move backward. Then, the fixed block 9 drives the first transmission rod 11 to drive the fixed rod 8 to expand outward, thereby increasing the diameter of the outlet 2, making it easier for the flushed necrotic tissue to enter the syringe.
