Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a temporary femoral vein catheter fixation device. Background Technology

[0002] Hemodialysis is one of the main renal replacement therapies for patients with kidney failure. Establishing an effective vascular access is crucial for ensuring the smooth progress of hemodialysis. Clinically, femoral vein catheterization is currently widely used as the vascular access method. However, during femoral vein catheterization (which may last for 4 weeks or even longer), patients may need to frequently travel to the hospital. During this process, pulling on the femoral vein catheter may cause sutures to dislodge or the catheter to slip out, and improper gauze fixation at the lower end of the catheter may lead to catheter exposure. In some patients, due to edema, the small clips on the temporary catheter may compress the edematous area, causing skin damage or indentation, or the adhesive tape may cause allergic skin reactions. All of these situations may increase the patient's risk of infection.

[0003] Because the femoral vein double-lumen indwelling catheter is placed close to the patient's thigh, its fixation is difficult, easily leading to catheter slippage and infection. In clinical practice, various simple catheter clamps and fixation straps are often used for temporary fixation of the femoral vein catheter. However, there is currently a lack of femoral vein temporary catheter fixation straps specifically designed for dialysis patients. This leads to many challenges for patients using temporary femoral vein catheters, such as skin allergies and pressure marks near the catheter puncture site, all of which can increase the risk of infection. In addition, cases of catheter protrusion at the lower end and catheter slippage due to suture dislodgement, resulting in the need for re-insertion, are also common.

[0004] CN211751707U discloses a femoral vein catheter fixator, which uses a plastic body and a C-shaped catheter buckle, combined with a self-adhesive elastic bandage leg fixation strap. The catheter is fixed by the C-shaped catheter buckle, avoiding direct contact with the patient's skin and reducing the risk of skin damage and pressure sores. However, this femoral vein catheter fixator is only fixed by an open C-shaped catheter buckle, and its stability still needs to be improved. Furthermore, the exposed femoral vein catheter still poses a risk of slippage and infection.

[0005] Therefore, there is an urgent need to develop a new femoral vein temporary catheter fixation device specifically designed for dialysis patients. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies, such as insecure fixation, easy detachment, and easy exposure of the lower end of the catheter, and to provide a temporary femoral vein catheter fixation device.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A temporary femoral vein catheter fixation device is used to fix a double-lumen femoral vein catheter to a patient's leg. The temporary femoral vein catheter fixation device includes a protective sleeve body and fixation straps connected to both sides of the protective sleeve body. The back of the protective sleeve body is provided with a fixation dressing for adhering to the skin of the leg.

[0009] The top of the protective case body is an open structure, and a sealing element is provided at the opening; the bottom of the protective case body is a sealed structure, and an adhesive element is provided at the bottom edge for sticking to the outer surface of the protective case body.

[0010] The protective sleeve body has a partition plate inside the cavity for separating the two branches of the femoral vein double-lumen indwelling catheter.

[0011] Furthermore, the protective sleeve body has long grooves for fixing straps on both sides of its edge.

[0012] Furthermore, both ends of the fixing strap can pass through the long groove of the fixing strap and be fixed by the fixing member at the end of the fixing strap.

[0013] Furthermore, the fastener is a hook and loop fastener, and the fastening strap has a loop fastener surface that can be attached and fixed to the hook and loop fastener.

[0014] Furthermore, the fixing band is an elastic band with tensile elasticity.

[0015] Furthermore, the width of the fixing strap is 4-6 cm.

[0016] Furthermore, the sealing elements are arranged horizontally and symmetrically, with a non-sealed portion between the sealing elements for the insertion of a femoral vein double-lumen indwelling catheter.

[0017] Furthermore, the seal is either disposable adhesive or Velcro.

[0018] Furthermore, the bottom of the protective case body is a foldable structure, and the bottom edge after folding upwards is fixed to the outer surface of the protective case body by an adhesive.

[0019] Furthermore, the adhesive is either disposable adhesive or Velcro.

[0020] Furthermore, the partition plate is arranged perpendicular to the inner walls of both sides of the protective sleeve body.

[0021] Furthermore, the partition plate has a structure that is wider at the top and narrower at the bottom.

[0022] Furthermore, a gap is left between the top of the partition plate and the main tube and bifurcation of the femoral vein double-lumen indwelling catheter, and a gap is left between the bottom of the partition plate and the bottom of the protective sleeve body.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The temporary femoral vein catheter fixation device of this utility model can firmly attach the protective sleeve body to the patient's leg by using a combination of fixation dressing and fixation strap. The sealing element, adhesive element and partition plate on the protective sleeve body can effectively fix the femoral vein double lumen indwelling tube and reduce the risk of contamination caused by exposure.

[0025] (2) The present invention can enhance the stability of fixation by using fixation dressing and fixation belt together. Patients do not need to worry about the catheter slipping due to pulling the catheter during walking, which would cause secondary catheter placement. Problems such as allergies, skin damage, and aggravated infection caused by repeated tearing of the adhesive tape near the skin puncture site can also be avoided.

[0026] (3) The temporary femoral vein catheter fixation device of this utility model can be flexibly adjusted according to the patient's leg circumference and the exposed length of the femoral vein catheter, and has good adjustability.

[0027] (4) The operation method of the temporary femoral vein catheter fixation device of this utility model is simple, and elderly dialysis patients can also use it directly, which has good practicality. Attached Figure Description

[0057] Each of the above embodiments can be implemented individually, or in any combination of two or more. The following detailed description of specific examples will further illustrate these embodiments.

[0058] Example 1:

[0059] This embodiment provides a temporary femoral vein catheter fixation device for fixing a double-lumen femoral vein indwelling catheter 1 to the patient's leg.

[0060] The temporary femoral vein catheter fixation device of this embodiment includes a protective sleeve body 2 and fixation straps 3 connected to both sides of the protective sleeve body 2. The back of the protective sleeve body 2 is provided with a fixation dressing 4 for adhesion to the skin of the leg. The protective sleeve body 2 is firmly adhered and fixed to the patient's leg by the combined use of the fixation dressing 4 and the fixation straps 3.

[0061] The top of the protective sleeve body 2 in this embodiment has an open structure, and a sealing element 5 is provided at the opening to seal the top opening as much as possible after the femoral vein double-lumen indwelling tube 1 is inserted into the protective sleeve body 2, so as to reduce contamination. The bottom of the protective sleeve body 2 has a sealed structure, so that the bottom of the femoral vein double-lumen indwelling tube 1 is placed in the protective cavity inside the protective sleeve body 2, preventing infection caused by the femoral vein double-lumen indwelling tube 1 being exposed. An adhesive element 6 is provided at the bottom edge of the protective sleeve body 2, which can be pasted onto the outer surface of the protective sleeve body 2 to facilitate adjustment according to the exposed length of the femoral vein double-lumen indwelling tube 1. A partition plate 7 is provided in the internal cavity of the protective sleeve body 2 to separate the two branches of the femoral vein double-lumen indwelling tube 1, so as to minimize the impact between the two branches.

[0062] The temporary femoral vein catheter fixation device in this embodiment can firmly attach the protective sleeve body 2 to the patient's leg by using the fixation dressing 4 and the fixation strap 3 together. The sealing element 5, the adhesive element 6 and the partition plate 7 on the protective sleeve body 2 can effectively fix the femoral vein double-lumen indwelling catheter 1 and reduce the risk of contamination caused by exposure.

[0063] Example 2:

[0064] This embodiment provides a temporary femoral vein catheter fixation device for fixing a double-lumen femoral vein indwelling catheter 1 to the patient's leg.

[0065] The difference from Embodiment 1 is that, in this embodiment, the protective sleeve body 2 has long grooves 21 for fixing straps on both sides. Both ends of the fixing strap 3 can pass through the long grooves 21 and be fixed by the fixing members 31 at the ends of the fixing strap 3. In this embodiment, the fixing member 31 can be a conventional hook and loop fastener, and the fixing strap 3 has a hook and loop fastener surface that can be attached and fixed to the hook and loop fastener surface.

[0066] In this embodiment, the fixation strap 3 is an elastic band with tensile elasticity, which can be adjusted according to the patient's leg circumference. The width of the fixation strap 3 is 4-6cm to prevent discomfort caused by the fixation strap 3 being too narrow.

[0067] Example 3:

[0068] This embodiment provides a temporary femoral vein catheter fixation device for fixing a double-lumen femoral vein indwelling catheter 1 to the patient's leg.

[0069] The difference from Embodiment 1 is that the sealing elements 5 in this embodiment are arranged horizontally and symmetrically, and there is a non-sealed part between the sealing elements 5 for the femoral vein double-lumen indwelling tube 1 to pass through. That is, the femoral vein double-lumen indwelling tube 1 extends from the center position of the top opening and is sealed and fastened by the sealing elements 5 on both sides respectively.

[0070] In this embodiment, the sealing element 5 is made of conventional disposable adhesive or Velcro to achieve an effective seal at the top opening of the protective cover body 2.

[0071] Example 4:

[0072] This embodiment provides a temporary femoral vein catheter fixation device for fixing a double-lumen femoral vein indwelling catheter 1 to the patient's leg.

[0073] The difference from Embodiment 1 is that the bottom of the protective sleeve body 2 in this embodiment is a foldable structure, and the bottom edge after folding upwards is fixed to the outer surface of the protective sleeve body 2 by adhesive 6. Since the exposed length specifications of the femoral vein double-lumen indwelling catheter 1 for hemodialysis produced by different manufacturers are not uniform, the lower edge of the protective sleeve body 2 adopts an upward foldable structure and is fixed by adhesive 6 to accommodate different temporary catheters.

[0074] In this embodiment, the adhesive 6 is made of conventional disposable adhesive or Velcro to effectively and temporarily fix the bottom edge after folding upwards.

[0075] Example 5:

[0076] This embodiment provides a temporary femoral vein catheter fixation device for fixing a double-lumen femoral vein indwelling catheter 1 to the patient's leg.

[0077] The difference from Embodiment 1 is that in this embodiment, the partition plate 7 is set perpendicular to the inner walls of both sides of the protective sleeve body 2, simply dividing the protective cavity inside the protective sleeve body 2 into two spaces. The partition plate 7 in this embodiment has a structure that is wider at the top and narrower at the bottom, with the bottom width narrowing to facilitate the folding and fixing of the bottom of the protective sleeve body 2. A certain distance is left between the top of the partition plate 7 and the main tube and bifurcation of the femoral vein double-lumen indwelling catheter 1 to prevent excessive height from restricting the insertion of the femoral vein double-lumen indwelling catheter 1; a distance is also left between the bottom of the partition plate 7 and the bottom of the protective sleeve body 2 to allow space for the folding and fixing of the bottom of the protective sleeve body 2.

[0078] Example 6:

[0079] This embodiment provides a disposable temporary femoral vein catheter fixation device for fixing a double-lumen femoral vein indwelling catheter 1 to the patient's leg.

[0080] The temporary femoral vein catheter fixation device of this embodiment includes a protective sleeve body 2 and fixation straps 3 connected to both sides of the protective sleeve body 2. Long grooves 21 for the fixation straps are provided on both sides of the protective sleeve body 2. Both ends of the fixation straps 3 can pass through the long grooves 21 and be fixed by fasteners 31 at the ends of the fixation straps 3. The fasteners 31 are hook and loop fasteners, and the fixation straps 3 have hook and loop fasteners that can be attached to the hook and loop fasteners. The fixation straps 3 are elastic bands with tensile elasticity, and the width of the fixation straps 3 is 5cm.

[0081] The protective sleeve body 2 of this embodiment has a fixing patch 4 on the back for adhering to the skin of the leg, which is a conventional medical sterile transparent film.

[0082] In this embodiment, the top of the protective sleeve body 2 is an open structure, and a sealing element 5 is provided at the opening for sealing. The sealing elements 5 are arranged horizontally and symmetrically, and a non-sealed part is left between the sealing elements 5 for the femoral vein double-lumen indwelling tube 1 to pass through. The sealing elements 5 are made of disposable adhesive, i.e., double-sided adhesive tape.

[0083] In this embodiment, the bottom of the protective case body 2 is a sealed structure, and an adhesive piece 6 is provided at the bottom edge for attaching to the outer surface of the protective case body 2. The bottom of the protective case body 2 is a foldable structure, and the bottom edge after folding upwards is attached and fixed to the outer surface of the protective case body 2 by the adhesive piece 6. In this embodiment, the adhesive piece 6 is a disposable adhesive.

[0084] In this embodiment, the internal cavity of the sheath body 2 is provided with a partition plate 7 for separating the two branches of the femoral vein double-lumen indwelling catheter 1. In this embodiment, the partition plate 7 is set perpendicular to the inner walls of both sides of the sheath body 2, and the partition plate 7 has a structure that is wider at the top and narrower at the bottom. A gap is left between the top of the partition plate 7 and the main tube and bifurcation of the femoral vein double-lumen indwelling catheter 1, and a gap is left between the bottom of the partition plate 7 and the bottom of the sheath body 2.

[0085] Example 7:

[0086] This embodiment provides a reusable temporary femoral vein catheter fixation device for securing a double-lumen femoral vein catheter 1 to a patient's leg. The difference from Embodiment 6 is that both the sealing element 5 and the adhesive element 6 in this embodiment are made of Velcro, facilitating repeated fastening. The opening and the outer surface of the protective sleeve body 2 are respectively provided with Velcro hooks that can mate with the hook side for adhesion.

[0087] The method of using the temporary femoral vein catheter fixation device in this embodiment is as follows:

[0088] Place the protective sleeve body 2 close to the patient's leg and insert the femoral vein double-lumen indwelling catheter 1. Insert the femoral vein double-lumen indwelling catheter 1 into the cavity of the protective sleeve body 2 and temporarily separate the two tubes using the partition plate 7. After adjusting to a suitable position, peel off the release paper of the fixation dressing 4 and attach it to the patient's leg. Then, wrap the fixation strap 3 around the patient's leg, adjust its position, and connect and fix both ends of the fixation strap 3 to the sides of the protective sleeve body 2. Once the protective sleeve body 2 is securely fixed, seal the top opening of the protective sleeve body 2 using the sealing element 5. Fold the bottom of the protective sleeve body 2 according to the length of the femoral vein double-lumen indwelling catheter 1 and attach it to the outer surface of the protective sleeve body 2 using the adhesive element 6. This completes the temporary fixation of the femoral vein double-lumen indwelling catheter 1.
