Description

Technical Field

[0001] This invention relates to the field of injection connector technology, and more particularly to a nutrient injection connector. Background Technology

[0002] Currently, the materials in the nutrient bags are added using a syringe.

[0003] However, existing nutrient injection connectors have the following drawbacks:

[0004] (1) During the process of adding materials, the syringe has poor connection stability between the syringe connector and the nutrient bag, resulting in low efficiency of injecting materials.

[0005] (2) Existing syringes typically employ an interference fit between a convex ring formed on the outside of the piston and the inner wall of the syringe barrel. However, the interference between the convex ring and the barrel is often quite large, resulting in significant sliding resistance between the piston and the inner wall of the syringe barrel, making injection difficult. To counteract the sliding resistance caused by the large interference, some manufacturers tend to increase the amount of silicone oil used, which contaminates the nutrient solution. Utility Model Content

[0006] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a nutrient injection connector that can improve the connection stability between the connector on the injection assembly and the nutrient bag.

[0007] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution:

[0008] A nutrient injection connector includes a nutrient bag and a connecting tube connected to the nutrient bag. A connector assembly is connected to the connecting tube. The connector assembly includes a Z-shaped sleeve fitted into the top opening of the connecting tube. The top of the Z-shaped sleeve is provided with an insert tube that can be inserted into the connecting tube. The Z-shaped sleeve is threadedly connected to the connecting tube. The top of the insert tube is connected to an injection assembly. The injection assembly can inject nutrient solution into the nutrient bag through the insert tube and the connecting tube.

[0009] Furthermore, the outer wall of the insertion tube abuts against the inner wall of the connecting tube.

[0010] Furthermore, a connecting assembly is fixedly provided at the top of the cannula, and the injection assembly is connected to the cannula through the connecting assembly. The connecting assembly includes a connecting cylinder one fixedly sleeved on the top of the cannula, a connecting cylinder two fixedly sleeved on the top of the connecting cylinder one, and a connecting cylinder three fixedly sleeved on the top of the connecting cylinder two. The diameter of the connecting cylinder two is larger than that of the connecting cylinder one, and the diameter of the connecting cylinder three is larger than that of the connecting cylinder two.

[0011] Furthermore, the injection assembly includes an injection cylinder, an injection tube communicating with the bottom of the injection cylinder, a piston disposed inside the injection cylinder, and a push rod disposed through the top opening of the injection cylinder and connected to the piston.

[0012] Furthermore, three convex rings are uniformly fixedly sleeved on the piston, and the outer wall of the convex rings abuts against the inner wall of the injection cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) When in use, connect the injection component to the cannula, insert the cannula into the connecting tube, and screw the Z-shaped sleeve onto the connecting tube. This method can improve the connection stability between the connector on the injection component and the nutrient bag, and prevent the connector on the injection component from detaching from the nutrient bag when the injection component injects material into the nutrient bag. Thus, compared with the prior art, it solves the technical problem of low efficiency of injecting material by the syringe due to poor connection stability between the syringe connector and the nutrient bag.

An injection assembly 13 is connected to the top of the insert tube 3. The injection assembly 13 can inject nutrient solution into the nutrient bag 1 through the insert tube 3 and the connecting tube 2.

[0023] The nutrient injection connector includes a nutrient bag 1 and a connecting tube 2 connected to the nutrient bag 1. A connector assembly 14 is connected to the connecting tube 2. The connector assembly 14 includes a Z-shaped sleeve 4 fitted onto the top opening of the connecting tube 2. An insert tube 3 is inserted through the top of the Z-shaped sleeve 4 and can be inserted into the connecting tube 2, so that the Z-shaped sleeve 4 is threadedly connected to the connecting tube 2. An injection assembly 13 is connected to the top of the insert tube 3, so that the injection assembly 13 can inject nutrient solution into the nutrient bag 1 through the insert tube 3 and the connecting tube 2. In use, the injection assembly 13 is connected to the cannula 3, the cannula 3 is inserted into the connecting tube 2, and the Z-shaped sleeve 4 is screwed onto the connecting tube 2. This method can improve the connection stability between the connector on the injection assembly 13 and the nutrient bag 1, and prevent the connector on the injection assembly 13 from detaching from the nutrient bag 1 when injecting materials into the nutrient bag 1. Thus, compared with the prior art, it solves the technical problem of low efficiency of injecting materials by the syringe due to poor connection stability between the syringe connector and the nutrient bag 1.

[0024] Furthermore, the outer wall of the insertion tube 3 abuts against the inner wall of the connecting tube 2, which improves the sealing of the connection.

[0025] Furthermore, a connecting component 15 is fixedly provided at the top of the cannula 3. The injection component 13 is connected to the cannula 3 through the connecting component 15. The connecting component 15 includes a connecting cylinder 12 fixedly sleeved on the top of the cannula 3, a connecting cylinder 2 11 fixedly sleeved on the top of the connecting cylinder 12, and a connecting cylinder 3 5 fixedly sleeved on the top of the connecting cylinder 2 11. The diameter of the connecting cylinder 2 11 is larger than that of the connecting cylinder 12, and the diameter of the connecting cylinder 3 5 is larger than that of the connecting cylinder 2 11.

[0026] A connecting component 15 is fixedly provided at the top of the cannula 3. The injection component 13 is connected to the cannula 3 through the connecting component 15. The connecting component 15 includes a connecting sleeve 12 fixedly sleeved on the top of the cannula 3, a connecting sleeve 2 11 fixedly sleeved on the top of the connecting sleeve 12, and a connecting sleeve 3 5 fixedly sleeved on the top of the connecting sleeve 2 11. The diameter of the connecting sleeve 2 11 is larger than that of the connecting sleeve 12, and the diameter of the connecting sleeve 3 5 is larger than that of the connecting sleeve 2 11. In use, the connecting sleeve 12 is inserted into the cannula 3, and different connecting sleeves can be selected for adaptation according to the diameter of the injection component 13 outlet, thus improving the applicability.

[0027] Furthermore, the injection assembly 13 includes an injection cylinder 6, an injection tube 7 connected to the bottom of the injection cylinder 6, a piston 8 disposed inside the injection cylinder 6, and a push rod 10 that passes through the top opening of the injection cylinder 6 and is connected to the piston 8. Three protruding rings 9 are uniformly fixedly sleeved on the piston 8, and the outer wall of the protruding rings 9 abuts against the inner wall of the injection cylinder 6.

[0028] The injection assembly 13 includes an injection cylinder 6, an injection tube 7 connected to the bottom of the injection cylinder 6, a piston 8 inside the injection cylinder 6, and a push rod 10 connected to the piston 8 passing through the top opening of the injection cylinder 6. Three convex rings 9 are evenly fixedly fitted on the piston 8, so that the outer wall of the convex rings 9 abuts against the inner wall of the injection cylinder 6. In this way, a seal is formed between the three convex rings 9 and the inner wall of the injection cylinder 6, and the contact area is reduced compared to the piston 8. This helps to reduce the sliding resistance between the piston 8 and the inner wall of the injection cylinder 6, avoiding the use of silicone oil to reduce resistance. Thus, compared with the prior art, it solves the technical problem that some manufacturers often increase the amount of silicone oil used to counteract the sliding resistance caused by the large interference fit, which will contaminate the nutrient solution.
