Embodiment 1

[0040] see Figure 1 to Figure 5 , a hemodialysis venous catheter fixing belt, including a fixing belt 2 and a set of limiting belts 3 for winding and fixing the main catheter 11 of the venous catheter, the tail of the main catheter 1 is bifurcated into an arterial catheter 12 and a venous catheter 13; A group of limiting bands 3 are symmetrically arranged on both sides of the main catheter 11, and one end of the limiting band 3 is connected to the outer surface of the fixing band 2; one of the limiting bands 3 can be selectively connected to the arterial catheter 12, and the other The limiting band 3 can be selectively connected to the venous catheter 13 . It should be noted that the limiting member 3 can also adopt other structural forms, such as chains, etc., and these structural forms are also within the protection scope of the present invention.

[0041] The outer surface of the fixing belt 2 is provided with an elastic mechanism 4 for adjusting the tension degree of the...

Embodiment 2

[0048] This embodiment only describes the content different from the foregoing embodiments, and the same content will not be repeated.

[0049] see Figure 6 ~ Figure 8 , a hemodialysis intravenous catheter fixing belt, the holding mechanism 5 is a sponge block 53, the sponge block 53 penetrates and protrudes from the inner and outer sides of the fixing belt 2, when the slider 41 slides and presses against the sponge block 53 , the part of the sponge block 53 located inside the fixing belt 2 can hold the main catheter 1 tightly.

[0050] The fixing belt 2 is an inner and outer double-layer mechanism, the inner side is a moisture-absorbing layer 21, and the outer layer is a heat-dissipating layer 22; in this embodiment, further improvement, the material of the moisture-absorbing layer 21 is sponge, and the material of the heat-dissipating layer 22 is carbon fiber mesh .

[0051] When this embodiment is in use, when the venous catheter is pulled and displaced due to the insert...

Abstract

The invention discloses a hemodialysis venous catheter fixing belt, which belongs to the technical field of venous catheter fixing equipment. The present invention comprises a fixing band and at least one set of limiters, one end of the limiter is connected to the outer surface of the fixation band; one of the set of limiters can be selectively connected to the arterial catheter, and the other can be selectively connected to the IV catheter. The fixing belt is provided with a tightening mechanism and an elastic mechanism, and the tightening mechanism is located on both sides of the main pipe; the elastic mechanism includes a slider that is slidably connected to the outer surface of the fixing belt, and the slider is sleeved on the limit piece. When tightening, the limit piece will pull the slider to slide and press against the clamping mechanism, so that the clamping mechanism presses and clamps the main guide tube. The beneficial effect of the present invention is that it can convert the pulling effect of the venous catheter into the holding force for the main catheter, which greatly limits the activity of the venous catheter, avoids its unplanned detachment from the blood vessel, and optimizes the The safety of the hemodialysis fixing belt reduces the pain of the patient.

Description

technical field [0001] The invention relates to the technical field of venous catheter fixing equipment, in particular to a hemodialysis venous catheter fixing belt. Background technique [0002] Hemodialysis is the main method to treat acute and chronic renal failure, stable, reliable and safe vascular access is the basic guarantee for the smooth progress of hemodialysis. The usual way to establish such vascular access in the prior art is to indwell a hemodialysis venous catheter in the patient's neck blood vessel, the end of the venous catheter protrudes from the patient's body, and the tail of the venous catheter has a "Y"-shaped bifurcation , are the arterial and venous ports, respectively. At present, the traditional fixation method for hemodialysis jugular venous catheter is to wrap the outside of the catheter with two pieces of sterile gauze and fix it on the patient's ear with adhesive tape to keep it sterile. The length of the exposed part of the catheter after wra...
