Description

Technical Field

[0001] This utility model relates to the field of medical and nursing equipment, and in particular to a PICC insertion point compression device. Background Technology

[0002] Peripherally inserted central venous catheterization, also known as PICC, involves inserting a catheter through a vein in the arm to reach a large vein near the heart. This avoids direct contact between chemotherapy drugs and the arm veins. Furthermore, the rapid blood flow in the large vein quickly dilutes the chemotherapy drugs, thus significantly reducing their irritation to the blood vessels. This effectively protects the veins of the upper limb, reduces the incidence of phlebitis, and alleviates patient pain.

[0003] Currently, after PICC insertion, the puncture site needs to be pressed with the hand for more than 20 minutes to prevent bleeding. Since the puncture site needs to be pressed with the hand, it is inconvenient to keep the hands free. In addition, the hand needs to be pressed for a long time, which can easily lead to arm muscle fatigue and arm soreness. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical problems and provide a PICC insertion puncture point pressing device.

[0005] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a PICC insertion puncture point pressing device, comprising a pressing component and a wearing device, characterized in that: the pressing component includes a pressing pad, a heat-applied patch is disposed inside the pressing pad, a control panel is provided on the upper end face of the pressing pad, a pressing groove is provided on the lower end face, and an isolation layer is detachably connected to the pressing groove; the wearing device includes a first winding strip and a second winding strip symmetrically disposed on both sides of the pressing pad, a pressure mechanism is movably sleeved on the first winding strip, a hook and loop fastener is provided on the lower surface of the first winding strip, and a hook and loop fastener is provided on the upper surface of the second winding strip.

[0006] Preferably, the heat patch is equipped with a temperature sensor; the temperature sensor is connected to the control panel.

[0012] The beneficial effects of this utility model are:

[0013] This invention effectively eliminates bruising through a hot compress, and the temperature of the hot compress can be adjusted according to the patient's needs. The pressure groove inside the pressure pad prevents the insertion tube from falling off. The isolation layer, which is detachably connected to the pressure pad, protects the puncture site and avoids the risk of bacterial infection from repeated use, ensuring the user's hygiene and safety while allowing for repeated use. The inflatable pad, which is movably connected to the first wrapping belt, is inflated through an inflation and deflation mechanism. The inflated pad can adjust the pressure applied to the puncture point, enhancing the coverage and pressing efficiency. The timer can be set to press for a specific time, and a buzzer will sound an alert when the time is up, solving the problems of insufficient or excessive pressing time. The Velcro at the ends of the first and second wrapping belts can be adjusted according to the circumference of the puncture arm, making it suitable for different patients.
