Description

Central venous catheter fixing device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a central venous catheter fixing device.

Background technique

Central venous catheter is a kind of intravascular catheter, which is placed in the large vein to measure the central venous pressure, which is used to evaluate the physiological parameters of circulation and estimate the amount of body fluid. Because of the purpose of measuring central venous pressure, some hospitals often use central venous pressure as a misnomer for CVC. Large-scale and rapid intravenous infusion often occurs in surgeries with large blood loss or emergency treatment to maintain blood pressure, long-term parenteral nutrition, long-term antibiotic injection, and long-term analgesic injection. For drugs that are more irritating to peripheral veins (small veins), such as amiodarone, they are injected through central venous catheters instead. Hemodialysis pipelines, such as plasma exchange or dialysis, chemotherapy for tumors, prevent the occurrence of chemical phlebitis, prevent drug extravasation, establish a good infusion channel for patients with repeated infusions, avoid the pain of repeated punctures, and establish an infusion channel for critically ill patients.

However, the central venous catheter in the prior art is generally fixed to the human body by ordinary medical tape when in use. The tape is easy to fall off after long-term use, so multiple operations are required to ensure the stability of fixation; and the tape is not breathable, which is easy to cause tube infection due to stuffiness, and it is easy to leave tape marks on the patient's skin, which is easy to cause damage to the patient's skin; at the same time, the lower part of the central venous catheter is uneven, and fixing it with tape is easy to cause the protruding part to imprint the patient's skin, making the patient less comfortable when using it; therefore, we propose a central venous catheter fixing device to solve the above problems.

Utility Model Content

The utility model aims to solve the shortcomings of the background technology and proposes a central venous catheter fixing device.

To achieve the above purpose, the technical solution adopted by the utility model is: a central venous catheter fixing device, comprising: a fixing belt, a first elastic belt, a first Velcro hook surface, a first Velcro fleece surface, a drawstring bag, a drawstring, a drawstring rope, a second elastic belt, a second Velcro hook surface, a second Velcro fleece surface, and a central venous catheter; a plurality of first elastic belts are arranged on both sides of the fixing belt; the first elastic belt on the left side is arranged with a first Velcro hook surface; the first elastic belt on the right side is arranged with a first Velcro fleece surface; a drawstring bag is arranged on one side of the bottom of the fixing belt; a drawstring is arranged on one side of the front side of the drawstring bag; drawstring ropes are arranged on both sides of the drawstring; second elastic belts are arranged on both sides of the outer wall of the drawstring bag; the second elastic belt on the left side is arranged with a second Velcro hook surface; the second elastic belt on the right side is arranged with a second Velcro fleece surface; a central venous catheter is arranged between the fixing belts.

Furthermore, six first elastic bands are provided, and the six elastic bands are arranged in pairs symmetrically, and the elastic bands on both sides correspond to the first Velcro hook surface and the first Velcro fleece surface respectively.

Furthermore, the fixing belt is arranged in a mesh structure.

Furthermore, the two cuff ropes are arranged in a symmetrical structure.
