Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a needle cap for an infusion tube puncture device. Background Technology

[0002] Infusion tube puncture devices are commonly used to puncture vials when injecting medications such as saline. The puncture devices are mostly made of plastic, but the tip is sharp. After use, the puncture device must be separated from the infusion tube and disposed of as a sharps instrument, which is a cumbersome process and a heavy workload for medical staff. Summary of the Invention

[0003] To address the above problems, this utility model provides a needle cap for an infusion tube puncture device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a needle cap for an infusion tube puncture device, comprising a needle cap body, the needle cap body being a hollow cylinder without a top, the needle cap body being fitted onto the infusion tube, the infusion tube head being provided with a puncture device and an air inlet plug, the top of the needle cap body being close to the puncture device and the air inlet plug, the side wall of the needle cap body being provided with a groove near the bottom, the groove being connected to a sliding groove, the sliding groove extending to the top of the needle cap body, the width of the sliding groove being smaller than the width of the groove, the sliding groove being connected to the fixed end of a baffle near the groove, and the free end of the baffle being inclined downwards.

[0005] Preferably, one side wall of the sliding groove is tangentially connected to the same side wall of the card slot, and the other side wall of the sliding groove is connected to the top wall of the card slot.

[0006] Preferably, the bottom of the needle cap body is provided with a through hole, and the infusion tube extends into the needle cap body through the through hole, the diameter of the through hole being larger than the outer diameter of the infusion tube.

[0007] Preferably, the side wall of the needle cap body is provided with at least one set of slots and sliding grooves, and the length of the sliding groove is greater than the length of the puncture device.

[0008] Preferably, the diameter of the slot is equal to the outer diameter of the air inlet plug pipe, and the air inlet plug pipe is cross-connected with the infusion pipe.

[0009] Preferably, the outer wall of the needle cap body is provided with a plurality of anti-slip blocks, which are distributed to avoid the slots and sliding grooves.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the needle cap body shields the puncture device, the sliding groove guides the air inlet plug's pipe into the slot, the slot fixes the air inlet plug's pipe, and the baffle prevents the air inlet plug's pipe from falling off, allowing the puncture device and the needle cap body to be treated as infectious waste together, avoiding the need for medical staff to sort and process the puncture device, thus reducing workload; when handling waste, the needle cap can prevent waste handlers from being pricked by the puncture device and causing infection.

[0017] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0018] Please refer to the reference. Figure 1 , Figure 4 and Figure 5 An embodiment of the present invention provides a needle cap for an infusion tube puncture device, comprising a needle cap body 1, which is a hollow cylinder without a top. The needle cap body 1 is fitted onto an infusion tube 2. The infusion tube 2 has a puncture device 3 and an air inlet plug 4 at its head end. The top of the needle cap body 1 is close to the puncture device 3 and the air inlet plug 4. The side wall of the needle cap body 1 is provided with a groove 12 near the bottom. The groove 12 is connected to a sliding groove 13 above it. The sliding groove 13 extends to the top of the needle cap body 1. The width of the sliding groove 13 is smaller than the width of the groove 12. The sliding groove 13 is connected to the fixed end of a baffle 11 near the groove 12. The free end of the baffle 11 is inclined downward.

[0019] The sliding groove 13 is used to guide the pipe of the air inlet plug 4 into the slot 12. The slot 12 is used to fix the pipe of the air inlet plug 4. The width of the sliding groove 13 is smaller than the width of the slot 12 so that the pipe of the air inlet plug 4 will not easily fall out of the slot 12. The baffle 11 is preferably a plastic sheet with a certain elasticity. The baffle 11 blocks the outlet of the slot 12 to prevent the pipe of the air inlet plug 4 from falling out. When the pipe of the air inlet plug 4 is stuck in the slot 12, the needle cap body 1 covers the puncture device 3 to prevent it from being punctured by the puncture device 3.

[0020] In one embodiment, such as Figure 1 As shown, one side of the sliding groove 13 is tangentially connected to the same side of the slot 12, and the other side of the sliding groove 13 is connected to the top wall of the slot 12, so that the pipe of the air inlet plug 4 can smoothly enter the slot 12 from the sliding groove 13.

[0021] In one embodiment, such as Figure 3 and Figure 4 As shown, the bottom of the needle cap body 1 is provided with a through hole 15, and the infusion tube 2 extends into the needle cap body 1 through the through hole 15. The diameter of the through hole 15 is larger than the outer diameter of the infusion tube 2, so that the needle cap body 1 can move along the infusion tube 2.

[0022] In one embodiment, such as Figure 1 and Figure 5 As shown, the side wall of the needle cap body 1 is provided with at least one set of slots 12 and sliding grooves 13, which are suitable for infusion tubes 2 with other branches at the puncture device 3 and air inlet plug 4. The length of the sliding groove 13 is greater than the length of the puncture device 3, ensuring that the sharp part of the puncture device 3 will not be exposed and avoid being scratched.

[0023] In one embodiment, such as Figure 4 and Figure 5 As shown, the diameter of the slot 12 is equal to the outer diameter of the inlet plug 4 pipe, which can hold the inlet plug 4 pipe in place and play a fixing role. The inlet plug 4 pipe is cross-connected with the infusion pipe 2.

[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, the outer wall of the needle cap body 1 is provided with several anti-slip blocks 14. The anti-slip blocks 14 are distributed to avoid the slot 12 and the sliding groove 13, which facilitates operation by medical staff and prevents slippage.

[0025] Usage: Combine Figures 1-5 As shown, the used puncture device 3 is pulled out of the medicine bottle, the needle cap body 1 is rotated so that the air inlet plug 4 is aligned with the sliding groove 13, and the needle cap body 1 is pushed towards the puncture device 3. The air inlet plug 4 is pushed along the sliding groove 13 and enters the slot 12 through the baffle 11. The puncture device 3 is located inside the needle cap body 1, completing the re-sheathing protection of the puncture device 3.

[0026] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
