Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an arterial sheath fixation device. Background Technology

[0002] Transcatheter hepatic artery infusion chemotherapy is a common treatment for patients with unresectable or palliative liver cancer. The catheter is typically advanced via the femoral artery to a designated location, and chemotherapy drugs are then continuously infused through an arterial sheath. To reduce chemotherapy-related adverse reactions, maintenance infusion is routinely performed using an infusion pump, with continuous treatment lasting 48-72 hours. The arterial sheath is removed only after treatment is completed.

[0003] Due to high arterial pressure, complete immobilization of the patient's lower limbs is difficult. Combined with adverse reactions from chemotherapy drugs, significant bleeding occurs at the arterial sheath. Because of concerns that managing bleeding and changing dressings might affect the sheath's position, dressing changes and bleeding management require returning the patient to the interventional radiology room. This frequently results in delayed bleeding management, posing a significant risk of catheter displacement and causing considerable inconvenience to the patient. Currently, there is no suitable arterial sheath fixation device; only transparent dressings are used for fixation. However, the fixation effectiveness is greatly reduced when there is bleeding within the transparent dressing.

[0004] Therefore, how to provide a fixation device specifically for arterial sheaths to improve the fixation effect between the arterial sheath and human skin, prevent the displacement of the arterial sheath, increase the local pressure effect, and reduce the risk of bleeding is a technical problem that urgently needs to be solved by those skilled in the art.

The sheath core 13 is connected to the other end of the arterial sheath 12. In use, both the arterial sheath 12 and the sheath core 13 are punctured into the patient's artery. The third end 113 is provided with a protruding structure. The hemostatic fixation component 2 is a disc-shaped structure with an internal groove. By setting the hemostatic fixation component 2 as a disc-shaped structure, the sheath connection portion 11 and the arterial sheath 12 connected to it are fixed in place. The arterial sheath 12 and extension tube 15 are covered and protected. The hemostatic fixing component 2 is designed with a groove inside according to the shape of the sheath connection part 11 and the arterial sheath 12 and extension tube 15 connected to it. The hemostatic fixing component 2 is covered on the sheath connection part 11 to ensure that the arterial sheath 1 cannot move within the fixing device. In this way, a fixing device specifically for the arterial sheath 1 is constructed, which improves the fixing effect between the arterial sheath 1 and the human skin, avoids the displacement of the arterial sheath 1, reduces the risk and amount of bleeding caused by catheter displacement, and can also compress and stop bleeding by covering and pressing the hemostatic fixing component 2 on the arterial sheath 1, increasing the local pressure effect, and absorbing a certain amount of bleeding to improve the hemostatic effect.

[0049] In some possible embodiments, the hemostatic fixing member 2 includes a housing 21 and a hemostatic layer 22.

[0055] Specifically, since both the arterial sheath 12 and the sheath core 13 are punctured into the patient's artery during use, the connection between the arterial sheath 12 and the first end 111 is partially exposed, and the connection between the arterial sheath 12 and the first end 111 is the main bleeding point, the shallow opening 25 is used to cover the exposed part of the arterial sheath 12 to avoid excessive compression, and at the same time, it can absorb blood.

[0056] In some possible implementations, the hemostatic layer 22 is made of medical absorbent dressing.

[0057] Specifically, the hemostatic layer 22 is made of a soft medical dressing with good water absorption. On the one hand, it can help absorb blood seepage, and on the other hand, it serves as an auxiliary tool for applying local pressure to prevent blood seepage at the puncture site.

[0058] In some possible implementations, the hemostatic fixation member 2 also includes a plurality of fixation stickers, one end of which is bonded to the outer shell 21 and the other end of which is bonded to human skin.

[0059] Specifically, by setting several fixing stickers, the hemostatic fixing component 2 is fixed to the human skin as a whole. As one possible method, four fixing stickers can be set and the four fixing stickers are respectively attached to the top of the outer shell 21, forming a cross-shaped fixing structure.

[0060] In some possible implementations, the hemostatic fixation member 2 may also include an adhesive pad 26 integrally formed with the housing 21, the adhesive pad 26 being arranged around the bottom of the outer side of the housing 21.

[0061] Specifically, the adhesive plate 26 facilitates the bonding of the hemostatic fixation piece 2 to the human skin when no fixation tape is available.

The curvature of the second half-ring 262 is greater than that of the first half-ring 261. A connecting groove is provided at the junction of the second half-ring 262 and the shallow opening 25, and the connecting groove is connected to the shallow opening 25.

[0063] Specifically, such as Figure 4 As shown, the adhesive disc 26 includes a first half-ring 261 and a second half-ring 262, and the first half-ring 261 and the second half-ring 262 are staggered from the first through channel 23 and the second through channel 24 to avoid pressing on the arterial sheath (12) and the protruding structure; at the same time, a connecting groove connected to the shallow opening 25 is also provided, so as to further fix the exposed part of the arterial sheath 12 through the connecting groove.

[0064] In some possible implementations, a plurality of ventilation holes 263 are uniformly provided through the first half-ring 261 and the second half-ring 262, and a non-woven adhesive layer 264 is provided on the inner side of the first half-ring 261 and the second half-ring 262, and is bonded to human skin through the non-woven adhesive layer 264.
