Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to multi-functional internal fistula safety cover.
Background
Hemodialysis is the most commonly used blood purification therapy at present, and is used for removing in vivo metabolites and harmful substances and maintaining electrolyte and acid-base balance by draining blood in a patient body into a dialyzer outside the body and utilizing solute concentration difference on two sides of a semipermeable membrane through dispersion, ultrafiltration, adsorption and convection; and simultaneously, the excessive water in the body is removed.
The vascular access of long-term hemodialysis patients mostly takes an arteriovenous internal fistula as a main access. When carrying out hemodialysis for patient, the arm of puncture side all generally is not fixed, and the patient can not independently move in disorder in the dialysis process, leads to internal fistula hematoma and the slippage of pjncture needle to and the cover and the heavy load of quilt, can not in time observe the oozing blood of pjncture needle department, lead to patient's oozing blood too much. Aiming at the situation, the clinically adopted solution is to add a wrist restraint strap to bind the wrist to limit the movement of the arm, and after the wrist is restrained, the wrist is too loose to play a restraining role; or the pressure is too tight, the internal fistula is pressed, and partial blood flow is blocked, so that the treatment and the service life of the internal fistula are influenced; moreover, if the patient with hemodialysis is restrained for a long time, the arms of the patient will be numb and soreness and distension, and the process is very painful.
Therefore, it is necessary to design a fistula protecting cover to assist hemodialysis patients to successfully perform hemodialysis treatment.
Disclosure of Invention
In order to solve the problems, the utility model discloses a multifunctional internal fistula protecting cover which has simple structure and convenient use, and a clamping groove is arranged in the cover, so that the bending and the disordering of the arm of a patient can be prevented; the transparent material is convenient for medical personnel to observe in real time.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides a multi-functional internal fistula safety cover, includes arm unable adjustment base, adjustment flap, arm guard shield, the arm guard shield is the dome structure, and the arm guard shield is made for transparent plastic, and arm guard shield inner wall is equipped with the draw-in groove, and arm guard shield lower extreme both sides are equipped with the spliced pole, arm unable adjustment base's up end is equipped with the arc recess along its length direction, the quantity of adjustment flap is 0-4 layer, the adjustment flap sets up in the arc recess, arm unable adjustment base's upper end both sides are equipped with the connecting hole that matches with the spliced pole, the setting that the arm guard shield can open and shut is on arm unable adjustment base.
As an improvement of the utility model, the lower end face of the clamping groove is arc-shaped.
As an improvement of the utility model, the number of the clamping grooves is 1-3.
As an improvement of the utility model, the two sides of the arm shield are provided with handles.
