Description

Technical Field

[0001] The utility model relates to the technical field of arterial sheath tubes, in particular to a femoral artery sheath tube with a fixing patch. Background Art

[0002] The femoral artery sheath is an essential access route for any neurointerventional surgery via the femoral artery. Only through the femoral artery can the sheath be coaxially delivered or exchanged for neurointerventional instruments, ensuring the smooth progress of the entire surgical procedure. However, during neurointerventional surgery, the femoral artery sheath often falls out of the blood vessel due to reasons such as the patient's lack of cooperation and excessive resistance when withdrawing the instrument. This can lead to prolonged surgery time, affect subsequent surgical operations, and even lead to medical risks such as poor patient prognosis. Currently, in clinical work, in order to avoid the above problems, two people are often required to work together. One person manually holds the femoral artery sheath, and the other person withdraws the instrument to prevent the femoral artery sheath from falling out of the blood vessel. However, such an operation is time-consuming and labor-intensive, and increases the manpower burden and prolongs the operation time. Utility Model Content

[0003] In order to overcome the technical defects of the existing two-person cooperative control of the femoral artery sheath, which is time-consuming and labor-intensive and prolongs the operation time, the utility model provides a femoral artery sheath with a fixing patch.

[0004] The utility model provides a femoral artery sheath with a fixed patch, comprising a sheath body, a hemostatic sheath seat and a three-way valve, wherein the hemostatic sheath seat is fixedly sleeved to the end of the sheath body, and the hemostatic sheath seat is connected to the three-way valve through a connecting tube; the utility model also comprises a flexible fixed patch, wherein the middle part of the flexible fixed patch is fixedly connected with a hard special-shaped slot, and the hard special-shaped slot is adapted to the hemostatic sheath seat and the end of the sheath body connected to the hemostatic sheath seat and the end of the connecting tube; and a notch is provided on the flexible fixed patch, and after the hemostatic sheath seat is engaged with the hard special-shaped slot, the end of the hemostatic sheath seat corresponds to the position of the notch; the lower surface of the flexible fixed patch is provided with an adhesive layer for adhering to the skin, and a dust-proof coating is adhered to the adhesive layer, and a dust-proof coating is adhered to the adhesive layer.

[0005] In the present invention, the femoral artery sheath body is adapted to the flexible fixing patch. Before use, the two are two independent disposable components. When performing neurointerventional surgery via the femoral artery, the sheath body is first placed in the femoral artery. Then, the hard special-shaped slot of the flexible fixing patch is aligned and connected with the hemostatic sheath seat and the sheath body end and the connecting tube end connected to the hemostatic sheath seat. After that, the flexible fixing patch is affixed to the patient's skin. At this time, the femoral artery sheath body and the flexible fixing patch are integrated into one. The flexible part of the flexible fixing patch can better fit the skin, and the hard special-shaped slot can limit and fix the hemostatic sheath seat, the sheath body end, and the connecting tube end. The flexible fixing patches on both sides of the notch serve to enhance the reinforcement strength. When in use, tear off the dust-proof film on the adhesive layer, and the femoral artery sheath can be accurately fixed to the inguinal area centered on the femoral artery puncture point through the flexible fixing patch. Regardless of whether the left or right femoral artery puncture is adopted, the fixing patch can properly fix the femoral artery sheath to prevent it from falling out of the blood vessel, ensure the smooth access of the femoral artery neurointervention surgery, and thus ensure the safe and smooth progress of the operation.

[0006] Preferably, the flexible fixing patch is made of polyurethane or non-woven fabric, and the hard special-shaped card slot is made of polyethylene, polypropylene or thermoplastic polyurethane rubber.

[0007] Compared with the prior art, the technical solution provided by the utility model has the following technical effects: the femoral artery sheath with a fixing patch has a simple structure and is easy to use, which can ensure that the femoral artery sheath remains in a fixed position during the operation, avoid the femoral artery sheath from accidentally falling out of the blood vessel, ensure that the necessary passage for neurointerventional surgery via the femoral artery is smooth, reduce the waste of human resources in clinical work, greatly reduce the chance of femoral artery sheath falling out, and ensure the safe and smooth progress of neurointerventional surgery.
