Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an arm bracket for PICC disinfection and catheter placement. Background Art

[0002] PICC catheterization technology is suitable for patients who need long-term infusion or chemotherapy. It mainly connects the catheter through the vein in the arm to the large blood vessels close to the heart to avoid direct contact between chemotherapy drugs and the arm vein. It has the advantages of less trauma and fewer complications. It has been widely used in clinical treatment. PICC catheterization is usually performed in one of the basilic vein, median cubital vein, and cephalic vein in the patient's antecubital fossa, and the catheter is directly inserted into the superior vena cava.

[0003] At present, before PICC puncture, the patient's arm on the puncture side is required to be fully abducted. Most patients cannot persist until the disinfection and catheterization are completed. One medical staff member is required to support and fix the patient's arm, and then another medical staff member performs disinfection and other operations. Human support of the arm cannot ensure that the arm is fixed in position, and it is difficult to effectively maintain the puncture position, which affects the efficiency and effect of PICC puncture.

DETAILED DESCRIPTION

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Example

[0019] like Figure 1-3 As shown, an arm bracket for PICC disinfection and catheterization disclosed by the utility model includes a fixing seat 1, a support rod 2 and a limiting seat 3. The fixing seat 1 is fixedly installed on the top of the support rod 2, and the limiting seat 3 is installed on the bottom of the support rod 2. A plurality of fixing belts 4 are fixed in sequence on both sides of the top of the fixing seat 1 along the arm abduction shape. The fixing belts 4 on both sides are fixedly connected with Velcro that can be bonded together. The position of the fixing belt 4 does not affect the disinfection puncture. The limiting seat 3 is provided with a groove 5 near the bed side, and the limiting seat 3 at the top of the groove 5 is provided with a limiting bolt 6.

[0020] The fixing seat 1 is tilted at the top of the support rod 2, and an arc groove 101 is opened at the top of the fixing seat 1. The arc groove 101 is opened along the shape of the arm abduction. The fixing belt 4 is sequentially arranged on both sides of the arc groove 101. The tilt angle of the fixing seat 1 fits the abduction angle of the patient's arm.

[0021] The limiting bolt 6 includes a limiting bolt 601 and a limiting pressure plate 602. The limiting bolt 601 is arranged on the top of the limiting seat 3, and the limiting pressure plate 602 is arranged in the groove 5. The bottom of the limiting bolt 601 passes through the limiting seat 3 and is fixedly connected to the limiting pressure plate 602. The limiting bolt 601 is threadedly connected to the limiting seat 3.
