Remaining needle anti-pressing nursing device

Abstract

The invention relates to the technical field of venous indwelling needles, in particular to an indwelling needle anti-pressing nursing device which comprises an indwelling needle body, a fixed anti-pressing cover is arranged on the indwelling needle body, a movable anti-pressing cover is arranged on the fixed anti-pressing cover, and a rotating assembly and a sliding assembly are installed on the movable anti-pressing cover. The positive pressure connector and the second three-way pipe are fixed to the lower portion of the movable anti-pressing cover through the rod sleeve and the short rod, when infusion is not needed, the connecting rod is inserted into the connecting sleeve through the control knob, and the movable anti-pressing cover and the fixed anti-pressing cover are fixed; the fixed anti-pressing cover and the movable anti-pressing cover can carry out anti-pressing nursing on the whole remaining needle, when infusion is needed, the connecting rod and the connecting sleeve are separated through the control knob, the movable anti-pressing cover is turned over to the position above the fixed anti-pressing cover, the first magnet block and the second magnet block are attracted, and the positive pressure connector and the second three-way pipe are completely exposed. Not only can the pressure-resistant nursing be carried out on the remaining needle, but also the infusion can be conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of intravenous indwelling needles, in particular to an anti-pressure nursing device for indwelling needles. Background technique [0002] The initial design intention of the indwelling needle is to reduce the pain caused by repeated venipuncture and the fear of injections in children, relieve the anxiety of parents, and facilitate clinical medication. Later, it is also used in patients who need long-term intravenous injection , can reduce the workload of medical staff, and can also avoid the need to puncture the patient's vein every time when performing intravenous infusion to the patient. [0003] When the indwelling needle is used, it is generally inserted into the patient's forearm vein with a metal puncture needle and a soft catheter. On the forearm, the extension tube is connected with a positive pressure joint, and the positive pressure joint is connected with a three-way pipe capable of communicating...

AI Technical Summary

Problems solved by technology

[0004] Because the three-way tube on the positive pressure connector needs to be connected with the infusion bottle every day, the extension tube and the positive pressure connector cannot be wrapped on the patient's forearm, but the extension tube and the positive pressure connector are glued to the patient's forearm by medical tape However, because the indwelling needle needs to be attached to the forearm for a long time, when the patient does not need infusion, the patient's voluntary activities or unconscious turning during rest may compress the indwelling needle, causing certain damage to the indwelling needle, and more likely The end cap on the tee tube connected to the infusion bottle falls off, which increases the risk of infection for the patient. Although there is a nursing device capable of preventing pressure on the entire indwelling needle in the prior art, it increases the risk of infection when infusion is required. The complexity of the connection between the three-way tube and the infusion bottle requires an anti-pressure care device for indwelling needles to solve the above problems
