Novel nursing device for hematodialysis puncturing

Abstract

The invention discloses a novel nursing device for hematodialysis puncturing. The device comprises a base, a first fixing piece and a second fixing piece; the base comprises a base plate, a left sideplate and a right side plate, the left side plate and the right side plate are arranged on the base plate, a first groove suitable for accommodating the arm is formed in the upper surface of the baseplate, and a locking piece is arranged at the lower surface of the base plate; the first fixing piece comprises a sliding plate and a first constrained plate, the left and right ends of the sliding plate are respectively slidably connected with the left side plate and the right side plate, the first constrained plate is arranged on the sliding plate and can move up and down along the sliding plate, and a first constrained groove is formed in the lower surface of the first constrained plate; the second fixing piece comprises two guiding rods and a second constrained plate, the two guiding rodsare oppositely arranged at the lower surface of the sliding plate at left and right, the second constrained plate is slidably arranged between the two guiding rods, a second constrained groove is formed in the lower surface of the second constrained plate, and an inflatable air bag is arranged on the groove ball of the second constrained groove. The device has the advantages that a better arm constraining effect is achieved, multiple functions are achieved, the practicability is high, and higher popularization value is achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a novel nursing device for hemodialysis puncture. Background technique [0002] Hemodialysis is one of the most common forms of renal replacement therapy. Dialysis is the movement of solutes from a solution of high concentration to a solution of low concentration through a semipermeable membrane. Hemodialysis includes the movement of solutes and water, that is, the blood and dialysate exchange substances in the dialyzer (artificial kidney) through semi-permeable membrane contact and concentration gradients, so that metabolic waste and excess electrolytes in the blood are transferred to the dialysate. Move, the calcium ions and bases in the dialysate move to the blood. If the mixture of albumin and urea is put into the dialyzer and the outside of the tube is soaked in water, the urea in the dialyzer tube will move to the water outside the tube through the pores of the artificial k...

Problems solved by technology

During dialysis, due to the establishment of extracorporeal blood circulation, the blood temperature is easily affected by the room temperature. Especially in winter, the patient needs to keep warm. In addition, the dialysis treatment usually takes 4-5 hours. Time usually enters the sleep state. However, the patient may touch the puncture needle or needle tube due to the movement of the arm or the slipping of the bedding during the unconscious physical activities of the patient during the dialysis process or when the bedding is covered, which will bring unnecessary accidental risks to the patient ( Touching the needle or the needle tube may cause the patient's puncture needle to fall off, resulting in massive bleeding, shock, and even death. Aiming at the problems existing in the current hemodialysis process, a fixed puncture protection device for hemodialysis internal fistula limbs is designed. It is necessary to ensure the smooth progress of the dialysis process
