Description

Technical Field

[0001] The utility model relates to the field of hospital supplies, in particular to an infusion connector protector. Background Art

[0002] Patients with indwelling intravascular infusion lines, such as PICCs and indwelling needles, often use an infusion set without a steel needle. The end of the infusion set tubing has an infusion set connector, which is threaded into the connector of the indwelling infusion line to achieve infusion. Some of these patients do not require continuous infusion; if an examination is required, the infusion can be paused for examination. Furthermore, patients undergoing surgeries such as joint replacements may need to temporarily perform functional exercises, and they can also pause the infusion to perform these exercises first.

[0003] To suspend the infusion in the above situation, simply disconnect the infusion set connector from the indwelling infusion line. After disconnecting the infusion set connector from the indwelling infusion line, the infusion set connector and indwelling line should be properly stored. Currently, a common method is to hang the infusion line on a hook on an infusion pole or infusion stand to prevent it from falling to the ground. Additionally, a protective cap is placed on the infusion set connector to prevent contamination.

[0004] This approach has several drawbacks. First, the infusion tube is simply hung on a hook, making it prone to slipping and falling to the ground. Second, the protective cap covering the infusion connector must be carried by the nurse and placed on the connector at all times, making it difficult to access anywhere and cumbersome.

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 6As shown, the infusion connector protector includes a protector shell 1, a protective sleeve 2, a partition 3, a push-out structure 5, a clip 4 and a connecting structure 7; the protector shell 1 includes a protective sleeve accommodating box 11 and a protective sleeve accommodating tube 12, the protective sleeve accommodating box 11 has a plurality of horizontally arranged protective sleeves 2, each protective sleeve 2 is stacked up and down, the front side wall of the protective sleeve accommodating box 11 has a through hole 111, the through hole 111 is opposite to the bottom protective sleeve 2, the protective sleeve accommodating tube 12 is connected to the front side wall of the protective sleeve accommodating box 11 and is coaxial with the through hole 111, and the protective sleeve 2 includes a flexible sleeve 22; the partition 3 is installed in the protective sleeve accommodating box 11. On the protective sleeve accommodating box 11, the partition 3 closes the through hole 111 and can be opened; the pushing structure 5 is connected to the rear side wall of the protective sleeve accommodating box 11 and is opposite to the bottom protective sleeve 2; when the partition 3 is opened, the pushing structure 5 can push the bottom protective sleeve 2 into the protective sleeve accommodating tube 12; the length of the protective sleeve 2 is greater than the length of the protective sleeve accommodating tube 12, so that when the protective sleeve 2 is pushed into the protective sleeve accommodating tube 12, the flexible sleeve 22 is exposed from the protective sleeve accommodating tube 12; the clip 4 is connected to the protective sleeve accommodating tube 12, and the clip 4 can clamp the exposed flexible sleeve 22; the connecting structure 7 is used to connect to the infusion pole 8 or the infusion stand.

[0026] like Figure 7 As shown, the utility model is installed on an infusion pole 8 or an infusion stand through a connecting structure 7. The connecting structure 7 can be as follows Figure 6 As shown, it is a clamp-type structure, which can clamp the infusion pole 8 or the infusion stand, thereby realizing the fixation of the utility model.

[0027] The protective cover accommodating box 11 should have an entrance for inserting the protective cover 2 and be covered with a lid. After the protective cover 2 is used up, a new protective cover 2 should be inserted. The width of the inner cavity of the protective cover accommodating box 11 should be appropriate, and in the width direction, it can just accommodate one protective cover 2.

[0028] When the patient pauses their infusion and removes the infusion set connector, they hang the infusion tube of the infusion set 9 on the infusion pole 8 or the hook of the infusion stand. The partition 3 is then operated to open the through hole 111. The ejection mechanism 5 is then operated to push the bottom protective sleeve 2 into the protective sleeve receiving tube 12, exposing the flexible sleeve 22 to the protective sleeve receiving tube 12. The partition 3 is then operated to close the through hole 111. The infusion set connector is then inserted into the protective sleeve 2, and the flexible sleeve 22 is clamped and deformed with the clamp 4. The clamp 4 also clamps the infusion tube, and the infusion set 9 is now completely stored. The ejection mechanism 5 pushes the bottom protective sleeve 2 into the protective sleeve receiving tube 12 and then retracts, causing the upper protective sleeve 2 to automatically fall down and become available for the next ejection. When the patient resumes the infusion, the clamp 4 is released, the infusion set connector is pulled out for use, and the protective sleeve 2 is then pulled out and discarded to prevent contamination of the infusion set connector by repeated use of the protective sleeve 2.

[0029] Protective sheath 2 covers the infusion set connector, while clip 4 clamps and flattens flexible sheath 22, creating a substantially enclosed space within protective sheath 2. This effectively protects the infusion set connector and prevents contamination. While flexible sheath 22 is deformed by the clamping, clip 4 also grips the infusion tube, securing it and preventing it from slipping off the hook on the infusion pole or IV stand.

[0030] The specific structure of the protective cover 2 is preferably as follows Figure 3 As shown, the protective cover 2 includes a hard cover 21, which is coaxially arranged with a flexible cover 22. The rear end of the hard cover 21 is closed, and the front end of the hard cover 21 is connected to the flexible cover 22. As mentioned above, the flexible cover 22 can be clamped to substantially close the protective cover 2. The hard cover 21 is used to prevent the protective cover 2 from being crushed when in use.

[0031] Furthermore, the infusion connector protector preferably includes an elastic ring 6, which is connected to the front end of the protective sleeve accommodating tube 12 and is coaxial with the protective sleeve accommodating tube 12. The elastic ring 6 is conical in shape with the small end facing forward; the outer diameter of the hard sleeve 21 is larger than the outer diameter of the flexible sleeve 22; the inner diameter of the front end of the elastic ring 6 is larger than the outer diameter of the flexible sleeve 22 and smaller than the outer diameter of the hard sleeve 21.

[0032] The elastic ring 6 prevents the protective cover 2 from falling out of the protective cover receiving tube 12 when it is pushed out. This effect is achieved because the inner diameter of the front end of the elastic ring 6 is smaller than the outer diameter of the hard cover 21. The clip 4 also prevents the protective cover 2 from falling out during use. After use, the protective cover 2 is removed. During removal, the hard cover 21 expands the elastic ring 6, allowing the protective cover 2 to be removed. The elastic ring 6 can be made of an elastic material such as rubber or silicone.

[0033] The specific structure of the clip 4 is preferably as follows: the clip 4 includes a hinge shaft 41, a splint 43, a torsion spring 42 and a flexible ring 44. The hinge shaft 41 is connected to the top of the protective sleeve accommodating tube 12. There are two splints 43. The upper ends of the two splints 43 are hinged to the hinge shaft 41. The torsion spring 42 separates the two splints 43. The flexible ring 44 is connected to the lower end of any one of the splints 43. When the two splints 43 are close together, the flexible ring 44 can be put on the lower end of the other splint 43, thereby preventing the two splints 43 from separating.

[0034] The torsion spring 42 separates the two clamping plates 43 so that the clip 4 is in a normally open state. When clamping the protective cover 2, the two clamping plates 43 are pinched together with two fingers, and then the flexible collar 44 is enclosed on the lower end of the other clamping plate 43 to prevent the clip 4 from opening.

[0035] The specific arrangement of the partition 3 is as follows Figure 2As shown, the protective cover receiving box 11 has a partition groove 112 , and the partition 3 is inserted into the partition groove 112 . Pushing and pulling the partition 3 can control the partition 3 to close or open the through hole 111 .

[0036] The ejection mechanism 5 preferably has the following specific structure: a rear sidewall of the protective cover container 11 defines an ejection rod hole 113; the ejection mechanism 5 includes an ejection sleeve 51 and an ejection rod 52. The ejection sleeve 51 is connected to the protective cover container 11 and faces the ejection rod hole 113. The ejection rod 52 is inserted into the ejection sleeve 51 and can pass through the ejection rod hole 113 to eject the protective cover 2. Furthermore, the ejection mechanism 5 preferably includes a spring 53, which pushes against the ejection rod 52.

[0037] By pushing and pulling the ejection rod 52, the ejection rod 52 slides back and forth, and the protective cover receiving box 11 can be entered and exited from the ejection rod hole 113. If the spring 53 is not provided, the ejection rod 52 needs to be manually pulled back after ejection. If the spring 53 is provided, the ejection rod 52 can automatically return to its original position after exit.
