Description

Technical Field

[0001] The utility model relates to the technical field of infusion ports, in particular to an infusion needle structure used for an infusion port. Background Art

[0002] An infusion port is a closed infusion device that is completely implanted in the human body. When used in conjunction with an infusion needle, it can effectively reduce the pain of long-term or repeated venous and arterial punctures for medication, and improve the therapeutic effect. In the prior art, the infusion needle of an infusion port is generally a butterfly-wing needle, the needle head of which is arranged perpendicular to the needle seat. After the needle head is inserted into the port body, the whole is fixed by covering it with a film.

[0003] In actual treatment, in order to prevent pressure sores, gauze is usually placed under the butterfly wing of the butterfly wing needle, and then fixed with a film. However, the operation of padding with gauze is generally troublesome, and the thickness of the pad is difficult to determine, and it usually depends on the experience of medical staff, resulting in low patient comfort. At the same time, after covering with a film, if the patient feels uncomfortable, the gauze cannot be adjusted unless the film is removed.

[0004] Therefore, we propose an infusion needle structure for an infusion port. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example:

[0030] See also Figure 1 -

[0031] Figure 4 , an infusion needle structure for an infusion port, comprising a needle seat 1 connected to the end of a hose 3, butterfly wings 4 are provided on both sides of the needle seat 1, and a needle body 2 is arranged perpendicular to the needle seat 1;

[0032] like Figure 1 As shown, a decompression pad 6 is fixedly provided at the bottom of the butterfly wing 4 for decompression. The decompression pad 6 under the butterfly wing 4 can effectively prevent pressure sores caused by long-term treatment. At the same time, it has high comfort, does not require manual padding of gauze, and is simple and convenient to operate.

[0033] In this embodiment, the pressure relief pad 6 is composed of an airbag pad 601 and a skin-friendly pad 602 from top to bottom. The amount of gas in the airbag pad 601 can be increased or decreased. The comfort of the pressure relief pad 6 can be ensured by the skin-friendly pad 602. The thickness of the entire pressure relief pad 6 can be adjusted by the inflatable and deflated airbag pad 601. After the film is covered, the stability of the butterfly wing 4 can be maintained by filling the airbag pad 601 with gas, or the pressure of the butterfly wing 4 can be reduced by releasing the gas in the airbag pad 601, so that the butterfly wing 4 can still be adjusted after the film is covered, without having to peel off the film and re-operate.

[0034] In actual treatment, the butterfly wing 4 needs to be fixed on the skin for a long time. If a fixed pressure is maintained for a long time, the patient will feel discomfort at the puncture site. In this embodiment, by adjusting the bulging degree of the airbag cushion 601, the "flexibility" of the butterfly wing 4 can be significantly improved, and the pressure can be increased or decreased according to the patient's needs to achieve an adjustable pressure effect. Under the premise of ensuring the stability of the infusion needle structure, the patient's comfort during infusion is improved. At the same time, the disturbance to the original infusion needle structure is small, and the improvement cost is low.

[0035] like Figure 1 As shown, the airbag cushion 601 is connected to a regulator 604 through an air pipe 603. The regulator 604 is used to control the amount of gas in the airbag cushion 601. The regulator 604 can be directly set as a valve to inflate the airbag cushion 601 through a pump or other equipment;

[0036] In order to further understand the state of the airbag cushion 601, a small pressure gauge may be provided on the air pipe 603, and the specific bulging degree of the airbag cushion 601 may be intuitively understood through the reading of the pressure gauge.

[0037] This embodiment also provides a regulator 604, whose specific structure is as follows: Figure 4 As shown: the regulator 604 includes an air cylinder 7 and a piston 8. The air cylinder 7 is connected to the airbag cushion 601 through an air pipe 603. The air cylinder 7 is a hollow cylinder. The piston 8 is movably arranged in the air cylinder 7. A screw rod 9 is rotatably mounted on the piston 8. The end of the screw rod 9 extends to the outside of the air cylinder 7 and is fixedly connected to a knob 10. The screw rod 9 is threadedly connected in a nut 11, and the nut 11 is fixedly mounted on the air cylinder 7.

[0038] The screw rod 9 can be rotated by turning the knob 10. The screw rod 9 rotates and moves left and right under the action of the nut 11. The left and right movement of the screw rod 9 drives the piston 8 to move left and right. When the piston 8 moves to the right, the gas in the cylinder 7 can be filled into the airbag cushion 601 through the air pipe 603, so that the airbag cushion 601 swells; on the contrary, when the piston 8 moves to the left, part of the gas in the airbag cushion 601 will be distributed to the cylinder 7, so that the airbag cushion 601 is deflated.

[0039] Thus, by turning the knob 10 to adjust the position of the piston 8, the inflation or deflation of the airbag cushion 601 can be controlled, and the operation is more convenient;

[0040] Of course, for those skilled in the art, other forms of regulator 604 may also be provided according to actual needs, and this embodiment only exemplifies two of them.

[0041] In this embodiment, the air tube 603 is arranged closely to the needle seat 1 and the hose 3 in an integrated state, which has a more beautiful appearance, a simple structure, and no clutter in the pipeline.

[0042] like Figure 1 and Figure 3 As shown, the needle body 2 is sleeved with a protective sleeve 5, which includes a cylinder 501, and the inner wall of the cylinder 501 is evenly provided with a plurality of soft convex balls 502 in an annular shape for clamping the needle body 2;

[0043] In this embodiment, three soft convex balls 502 are provided, and the needle body 2 is located between the three soft convex balls 502. The three soft convex balls 502 are pressed on the needle body 2 to complete the positioning of the needle body 2.

[0044] By sleeve-mounting the protective tube 5 on the needle body 2, it is possible to prevent the needle body 2 from being stabbed and also prevent the needle body 2 from being contaminated by the outside.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
