Description
Technical Field
The utility model relates to human living goods, in particular to medical equipment, and in particular relates to a device for fixing and adjusting hemodialysis catheters.
Background
Hemodialysis is one of the main kidney replacement treatment methods for patients with renal failure, and establishing an effective vascular access is a precondition that hemodialysis is carried out smoothly, and the vascular access is called a "life line" of uremic patients, and some international and domestic research analyses indicate that currently, more than 60% of hemodialysis patients adopt an access type of CVC for the first dialysis, and is also called a "temporary catheter". In the prior art, in the hemodialysis process, a dialysis pipeline is divided into an artery and vein two catheters outside a patient, and the two catheters are parallel and close in the patient, and as the patient often needs to change the body position, the catheters are pulled, the position of the end part of the catheter in the body is changed, so that insufficient blood flow of the catheters is easily caused, and the dialysis treatment is interrupted. If the caregivers frequently manually adjust the external catheter position to adjust the internal catheter position, the incidence of catheter-related infections is easily increased.
Disclosure of Invention
The utility model aims to provide a device for fixing and adjusting a hemodialysis catheter, which aims to solve the technical problems that the hemodialysis catheter is inconvenient to fix and adjust in the prior art.
The utility model relates to a device for fixing and adjusting a hemodialysis catheter, which comprises a first semicircular body and a second semicircular body, wherein the first semicircular body and the second semicircular body are connected through a buckle to form a circular ring, at least two first clamping blocks are arranged on the inner circumferential surface of the first semicircular body along the circumferential direction, at least two second clamping blocks are arranged on the inner circumferential surface of the second semicircular body along the circumferential direction, and a clamping groove is formed between any two adjacent first clamping blocks or between any two second clamping blocks.
Further, the number of the first clamping blocks and the second clamping blocks is three.
Compared with the prior art, the utility model has positive and obvious effects. The device for fixing and adjusting the hemodialysis catheter is convenient to operate, and can directly rotate and adjust the catheter and fix the catheter at any angle, so that a proper angle is searched, the blood flow required during dialysis is met, the blood flow is optimal, the dialysis sufficiency of a patient is improved, the catheter can be quickly adjusted after the body position of the patient is changed, the forced fixing of the patient caused by meeting the blood flow is reduced, and the comfort level of the patient is improved. By adjusting the device to adjust the catheter, the direct contact of the hand of the caregiver with the dialysis catheter can be avoided, thereby reducing blood flow infections associated with the catheter.
Drawings
Fig. 1 is a schematic view of an apparatus for securing and adjusting hemodialysis catheters of the present utility model.
Description of the embodiments
The present utility model is further described below with reference to the drawings and examples, but the present utility model is not limited to the examples, and all the similar structures and similar variations using the present utility model should be included in the protection scope of the present utility model. The use of the directions of up, down, front, back, left, right, etc. in the present utility model is only for convenience of description, and is not a limitation of the technical scheme of the present utility model.
As shown in fig. 1, the device for fixing and adjusting a hemodialysis catheter according to the present utility model includes a first semicircular body 1 and a second semicircular body 2, wherein the first semicircular body 1 and the second semicircular body 2 are connected by a buckle to form a ring, at least two first clamping blocks 3 are circumferentially disposed on an inner circumferential surface of the first semicircular body 1, at least two second clamping blocks 4 are circumferentially disposed on an inner circumferential surface of the second semicircular body, and a clamping groove 5 is formed between any two adjacent first clamping blocks 3 or between any two second clamping blocks 4.
Further, the number of the first clamping blocks 3 and the second clamping blocks 4 is three.
Specifically, the first semicircular body 1, the second semicircular body 2, the buckle, the ring, the first clamping block 3, the second clamping block 4, the clamping groove 5 and the like in this embodiment all adopt the known schemes in the prior art, and those skilled in the art will understand that the description is omitted herein.
The working procedure of this embodiment is:
before hemodialysis treatment, place aseptic dressing on patient's skin, unpack apart first semicircle ring body 1 and second semicircle ring body 2, place dialysis catheter artery and vein pipeline two parts respectively in two draw-in grooves 5, buckle, first semicircle ring body 1 and second semicircle ring body 2 are connected as a whole, rotate this device, look for suitable angle, make external artery and vein way rotate, thereby drive internal catheter angle adjustment, make dialysis catheter blood flow optimum, utilize aseptic dressing to wrap up this device after the adjustment, and paste aseptic auxiliary material and fix on patient's skin with the sticky tape, make this device fix, maintain this angle. When the patient is subjected to actions such as posture change and the like and the blood flow of the dialysis catheter is insufficient during dialysis treatment, the adhesive tape is torn, the device is rotated, the angle of the proper dialysis catheter is adjusted again, the blood flow of the dialysis catheter is increased, and the device is fixed by wrapping the dialysis catheter with sterile dressing and sticking the adhesive tape on the skin.
The device has the diameter of 6cm and the height of 5cm, is made of resin, can be repeatedly used after being disinfected, and prevents cross infection.
The device for fixing and adjusting the hemodialysis catheter is convenient to operate, and can directly rotate and adjust the catheter and fix the catheter at any angle, so that a proper angle is searched, the blood flow required during dialysis is met, the blood flow is optimal, the dialysis sufficiency of a patient is improved, the catheter can be quickly adjusted after the body position of the patient is changed, the forced fixing of the patient caused by meeting the blood flow is reduced, and the comfort level of the patient is improved. By adjusting the device to adjust the catheter, the direct contact of the hand of the caregiver with the dialysis catheter can be avoided, thereby reducing blood flow infections associated with the catheter.
