Description

Limb fixing device for hemodialysis

The technical field is as follows:

the utility model relates to a fixing device, in particular to a hemodialysis limb fixing device.

Background art:

the arteriovenous internal fistula is used as a 'life line' of a maintenance hemodialysis patient, and is the basic guarantee for the smooth dialysis treatment of the patient. However, in dialysis treatment, the puncture needle is often separated or the blood vessel wall is punctured due to posture change or involuntary limb movement of a patient, so that complications such as bleeding, subcutaneous hematoma and the like occur, blood loss is caused, certain pain is brought to the patient, and unnecessary work burden of medical staff is increased; the treatment is delayed seriously, and even the life safety of the patient is endangered, and the result is unthinkable.

At present, the traditional conventional dialysis side limb restraint strap used by dialysis patients has obvious defects. 1. The wrist of a dialysis patient is the part where the arteriovenous internal fistula is located, the part cannot be pressed in the dialysis process, and once the part is pressed, the internal fistula blood vessel is blocked; however, the traditional restraint strap realizes restraint fixation by fixing the wrist and the bed body of the patient. 2. The traditional restraint strap only fixes the wrist of a patient, the elbow joint of the patient is not fixed, a dialysis blood loop is just positioned at the elbow joint of the patient for hemodialysis treatment, and a puncture needle is easy to drop out or puncture the blood vessel wall when the elbow joint of the patient moves. 3. When a patient carries out dialysis treatment at present, a hemodialysis pipeline is fixed on a sickbed sheet by using vascular clamps or adhesive tapes, when limbs of the patient move, the pipeline cannot be finely adjusted along with the movement of the limbs, but an accident caused by traction can be formed, and meanwhile, the pipeline is fixed on the sheet and is easy to be involved under the body of the patient or under bedding to cause the accident; and once the puncture needle is separated or the blood vessel wall is punctured, medical staff need to quickly establish a new puncture point and need to emergently treat bleeding or subcutaneous hematoma which already appears, so that the damage to a patient is reduced to the minimum, and the workload of the medical staff is increased. 4. In the dialysis treatment process of more than four hours, the dialysis side arm of a patient is required to be exposed for convenient observation and avoiding unnecessary traction of a hemodialysis pipeline, but when the temperature is low, the blood vessel of the dialysis side arm of the patient is easy to shrink, the lumen of the blood vessel is narrow, the arm of the patient is easy to feel painful, sour and swollen and uncomfortable, and even the patient can finish the treatment in advance.

The utility model has the following contents:

an object of the utility model is to provide a hemodialysis limbs fixing device that rational in infrastructure, use comfortable, alleviate medical staff's work burden, effectively avoid the pjncture needle to deviate from the emergence.

The utility model discloses by following technical scheme implement: the hemodialysis limb fixing device comprises a fixing base plate and a protective cover with a vent hole, wherein the fixing base plate comprises a fixing plate and a cloth cover sleeved outside the fixing plate, the fixing plate comprises a rectangular plate, a pair of short edges of the rectangular plate are respectively provided with a semi-elliptical plate, and a pair of fixing grooves are symmetrically arranged on the side edge of the rectangular plate close to one end of the semi-elliptical plate; a palm fixing band is arranged between the pair of fixing grooves, and a pair of fixing bands are arranged at the front end of the cloth cover close to one end of the fixing groove; two elastic bands are symmetrically arranged on two sides of the cloth cover far away from the other end of the fixing groove respectively, and two pipeline buckles are arranged on the elastic bands far away from one side of the fixing base plate; the fixed backing plate is fixed on the protective cover through a fixed structure.

Furthermore, fixed knot constructs including setting up a pair of backing plate fixed ring and the corresponding setting of fixed backing plate one side are in the solid fixed ring of a pair of cover body at protection casing base edge, the solid fixed ring of backing plate the solid fixed ring of the cover body is fixed through L shape bolt.

Further, the protection casing is transparent U-shaped cover.

Further, a soft cushion with the same shape and size as the fixed plate is arranged above the fixed plate; the soft pad is arranged in the cloth cover.

Furthermore, the distance between the fixed groove and one end of the fixed backing plate is 10cm, and the fixed groove is a semicircular groove with the radius of 3.5 cm.

The utility model has the advantages that: during application, the arm of a patient is placed in a fixed space formed by the fixed base plate and the protective cover, and the whole fixing device is fixed on a patient bed, so that the wrist of the patient is prevented from being directly fixed, and the internal fistula is prevented from being blocked; the utility model can fix and protect the wrist, elbow joint and upper arm of the patient, effectively protect the blood vessel of the dialysis blood loop at the elbow joint, and avoid the falling off of the puncture needle or the puncture of the blood vessel wall caused by the elbow joint movement of the patient; because the fixed protection of patient's arm forms independent portable fixing device in the protection casing, fixes hemodialysis pipeline together in fixing device with patient's arm simultaneously, avoids the accident that the patient acted the action to involve hemodialysis pipeline formation by accident, consequently more makes things convenient for medical staff's nursing and patient's adjustment in the use, makes things convenient for medical staff's work promptly, can alleviate patient's uncomfortable sense again.
