Description

Hemodialysis catheter fixing and recovering box

Technical Field

The utility model relates to a medical appliance structure, in particular to a hemodialysis catheter fixing and recovering box.

Background

During hemodialysis, two internal fistula needles are respectively inserted into an artery and a vein of an internal fistula of a patient, and a circulating system is formed by a hemodialysis pipeline, the internal fistula needles and a dialyzer. The traditional hemodialysis and blood returning operation process has the following defects: 1. the dialysis tubing is inconvenient to fix: the pipeline is fixed on a bed sheet or patient clothes by a plastic vessel clamp or a large-size long-tail ticket clamp under the common conditions, the head part of the plastic vessel clamp is easy to damage and scrap, the patient feels heavy when the ticket clamp is fixed on the clothes, and the patient feels cold when the clothes is thin during dialysis, and the ticket clamp is seriously corroded after being soaked and disinfected by a chlorine-containing disinfectant; 2. the internal fistula puncture needle is inconvenient to treat: the internal fistula puncture needles are disposable, and generally need to be separated by bare hands and thrown into a special sharp instrument box for centralized treatment after use, the height of the sharp instrument box is shorter than the length of the internal fistula needles, the internal fistula needles are not easy to enter the sharp instrument box and are easy to have needle stick injuries, and blood exposure risks and medical waste weight are increased because blood in a tube cavity cannot be discharged when the internal fistula needles are thrown into the sharp instrument box; 3. the waste liquid is inconvenient to discharge: when the waste liquid is discharged, the pipeline needs to be separated from the internal fistula needle by hands, the waste liquid is discharged after being connected by the arteriovenous connector, and blood drips out easily at the interface when the pipeline is separated from the internal fistula needle by hands and is connected with the arteriovenous connector, so that the blood exposure risk exists.

The hemodialysis catheter fixing and recovering box comprises a box body and a box cover, wherein one side edge of an upper opening of the box body is connected with one side edge of the box cover; the upper edges of the two ends of the rear wall of the box body are respectively provided with a notch, the width of the notch is equal to the outer diameter of the hemodialysis catheter, and the depth of the notch is greater than the outer diameter of the hemodialysis catheter; the back wall of the box body is provided with a handle extending backwards, a U-shaped pipe is fixed in the box body, two pipe orifices of the U-shaped pipe face the front wall of the box body, the opposite positions of the two pipe orifices of the U-shaped pipe on the front wall of the box body are respectively provided with an opening, two pipe orifices of the U-shaped pipe are provided with threads, and two pipe orifices are respectively screwed with a heparin cap.

When hemodialysis is carried out, two hemodialysis catheters can be respectively embedded into notches at the upper edges of the two ends of the front wall and the rear wall of the box body, the box cover is covered, the hemodialysis catheters can be hung on the clothes button by utilizing the handles on the box body, the effect of fixing the hemodialysis catheters is achieved, and a patient can move freely; the adhesive plaster can also be adhered to any nearby objects. After the dialysis, can inject the syringe needle respectively into the heparin cap on two mouths of pipe of U-shaped pipe after the internal fistula needle is extracted, carry out closed waste liquid through the U-shaped pipe and discharge, can prevent that the acupuncture from hindering and blood exposes.

fig. 3 is a schematic view of a second application of the hemodialysis catheter fixing and recovering box.

Detailed Description

As shown in fig. 1, the hemodialysis catheter fixing and recovering cassette includes a cassette body 1 and a cassette cover 10. One side edge of the upper opening of the box body is connected with one side edge of the box cover, the upper edges of the two ends of the front wall 3 of the box body are respectively provided with a notch 2 and a notch 8, the width of the notch is equal to the outer diameter of the hemodialysis catheter, and the depth of the notch is larger than the outer diameter of the hemodialysis catheter. The upper edges of the two ends of the back wall 16 of the cassette each have a

recess

14, 18, the width of which is equal to the outer diameter of the hemodialysis catheter and the depth of which is greater than the outer diameter of the hemodialysis catheter. The rear wall 16 of the box body is provided with a handle 15 extending backwards, a U-shaped pipe 17 is fixed in the box body, two pipe orifices 9 and 19 of the U-shaped pipe face the front wall 3 of the box body, the positions of the front wall 3 of the box body, which are opposite to the two pipe orifices of the U-shaped pipe, are respectively provided with an opening 4 and an opening 6, the two pipe orifices of the U-shaped pipe are provided with threads, and the two pipe orifices are respectively screwed with a heparin cap 5 and a heparin cap 7. Fig. 1 shows 11 and 12, which are small hooks on the box cover 10 for fastening with the box body 1.

As shown in fig. 2, in hemodialysis, two

hemodialysis catheters

20 and 21 are respectively inserted into the notches of the upper edges of the two ends of the front wall and the rear wall of the box body, in the figure, the catheter 20 is inserted into the
