Description

Technical Field

[0001] This utility model relates to the field of human daily necessities, and more particularly to medical devices, especially a leg hemodialysis catheter fixation device. Background Technology

[0002] Currently, in clinical practice, the establishment and implementation of blood flow access for patients undergoing bedside CRRT (Continuous Renal Replacement Therapy) in the ICU takes a long time. Therefore, securing the tubing is a crucial aspect of nursing care. For femoral vein catheter dialysis, the most common methods used in clinical practice are either hemostatic forceps or adhesive tape fixation. With these methods, a considerable length of the blood flow tubing is usually exposed and scattered around the patient's bedside. When the patient is uncooperative or has impaired consciousness, accidental traction can easily lead to tubing slippage, disrupting the continuous bedside hemodialysis treatment, threatening patient safety, and potentially causing adverse events. Utility Model Content

[0003] The purpose of this invention is to provide a leg hemodialysis catheter fixation device, which aims to solve the technical problem of poor fixation effect of femoral vein hemodialysis tubing in the prior art.

[0004] This utility model discloses a leg hemodialysis catheter fixation device, which includes a fixation sleeve and a waist support. The outer side of the fixation sleeve is provided with multiple Velcro fixing strips. One side of the fixation sleeve is connected to an outer fixing layer. The other side of the fixation sleeve and the side of the outer fixing layer away from the fixation sleeve are provided with a first connecting component. The upper end of the fixation sleeve is connected to an annular elastic bandage. The upper side of the elastic bandage is connected to a fixing strap. The upper end of the fixing strap is connected to the waist support.

[0005] Furthermore, the first connecting component is a male / female snap or Velcro.

[0006] Furthermore, the lumbar support is a strip structure, and a second connecting component is provided at both ends of the lumbar support. The second connecting component is Velcro.

[0007] Furthermore, a third connecting component is provided on the outer side of the lumbar support and the upper end of the fixing strip. The third connecting component is a male and female buckle or Velcro.

[0008] Furthermore, the lumbar support has an opening in the middle, and the fixing strap passes through the opening from the lower inner side of the lumbar support. The fixing strap is connected to the upper outer side of the opening of the lumbar support through a third connecting component.

[0009] Furthermore, the multiple Velcro fasteners are arranged in two columns, with three Velcro fasteners in each column.

[0010] Furthermore, a heating pocket is provided on one side of the outer fixing layer.

[0011] Furthermore, the fixing sleeve is an expandable bandage cloth, and the two ends of the bandage cloth are provided with a fourth connecting component, which is a Velcro.

[0012] Compared with existing technologies, the advantages of this invention are positive and significant. This invention, through a dual-fixation structure at the waist and legs, uses a Velcro fastener to secure the catheter while simultaneously providing an outer fixation layer covering the outside of the Velcro fastener. This ensures effective catheter fixation during routine pressure injury prevention and turning of critically ill patients, as well as during periods of agitation in critically ill patients, preventing catheter dislodgement and guaranteeing continuous bedside renal treatment.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention. Example

[0018] like Figure 1As shown, this utility model discloses a leg hemodialysis catheter fixation device, comprising a fixation sleeve 2 and a lumbar support 6. Multiple Velcro fastening strips 21 are provided on the outer side of the fixation sleeve 2. An outer fixation layer 3 is connected to one side of the fixation sleeve 2. A first connecting component 4 is provided on the other side of the fixation sleeve 2 and the side of the outer fixation layer 3 away from the fixation sleeve 2. An annular elastic bandage 1 is connected to the upper end of the fixation sleeve 2. A fixing strap 5 is connected to the upper side of the elastic bandage 1, and the lumbar support 6 is connected to the upper end of the fixing strap 5. The elastic bandage 1 and the fixation sleeve 2 are fitted onto the outer side of the patient's leg for fixation. The Velcro fastening strips 21 are used to fix the catheter 10. The outer fixation layer 3 covers the outer side of the Velcro fastening strips 21 after the catheter 10 is fixed, and is fixed by the first connecting component 4, further protecting the fixed position of the catheter 10. The lumbar support 6 is fixed to the patient's waist. The elastic bandage 1 is connected to the lumbar support 6 through the fixing strap 5, which can prevent the fixation sleeve 2 from moving downwards, keeping the fixation sleeve 2 in a fixed position.

[0019] Furthermore, the first connecting component 4 is a male / female snap or Velcro. Using male / female snaps and Velcro allows for quick connection and disassembly, facilitating reuse.

[0020] Furthermore, the lumbar support 6 is a strip structure, and a second connecting component 7 is provided at both ends of the lumbar support 6. The second connecting component 7 is Velcro.

[0021] Furthermore, a third connecting component 8 is provided on the outer side of the lumbar support 6 and the upper end of the fixing strap 5. The third connecting component 8 is a male and female buckle or Velcro. The detachable structure between the lumbar support 6 and the fixing strap 5 ensures that the lumbar support 6 and the elastic bandage 1 do not interfere with each other when worn or slipped onto the patient's limb. They are then connected by the third connecting component 8. The male and female buckle and Velcro can be quickly connected and disconnected.

[0022] Furthermore, the lumbar support 6 has an opening 61 in the middle, and the fixing strap 5 passes through the opening 61 from the lower inner side of the lumbar support 6. The fixing strap 5 is connected to the upper outer side of the opening 61 of the lumbar support 6 through the third connecting component 8. When the fixing strap 5 passes through the opening 61 and connects to the lumbar support 6, the lower side of the lumbar support 6 presses against the outer side of the fixing strap 5 to prevent the fixing strap 5 from falling off.

[0023] Furthermore, the multiple Velcro fastening strips 21 are arranged in two columns, with three Velcro fastening strips 21 in each column. During hemodialysis, it is generally necessary to secure two catheters 10. The two columns of Velcro fastening strips, with three strips in each column, facilitate the secure fixing of the two catheters 10.

[0024] Furthermore, a heated pocket 31 is provided on one side of the outer fixing layer 3. Specifically, the heated pocket 31 can be placed on the inner side when the outer fixing layer 3 covers the Velcro fixing strip 21. A heating pack can be placed in the heated pocket as needed to keep the patient warm and improve patient comfort. At the same time, it can reduce the use of blankets and facilitate observation by medical staff during hemodialysis.

[0025] In this embodiment, the elastic bandage 1 and the fixation sleeve 2 are first put onto the patient's limb, and the outer fixation layer 3 is unfolded. Then, the catheter 10 is fixed with the Velcro fastening strip 21. A heating pack can be placed in the heating pocket 31 to keep the patient warm, depending on their needs. Then, the patient is put on the lumbar support 6, and the fixation strap 5 is passed through the opening 61 from the inside of the lumbar support 6. The fixation strap 5 is connected to the outside of the lumbar support 6 through the third connecting component 8. Example

[0026] like Figures 2-3 As shown, the difference between this embodiment and embodiment 1 is that the fixing sleeve 2 is an unfoldable bandage cloth, and the two ends of the bandage cloth are provided with a fourth connecting component 9, which is a Velcro.

[0027] In this embodiment, the fixation sleeve 2 and the outer fixation layer 3 are first unfolded, and the elastic bandage 1 is placed over the patient's limb. Then, the fixation sleeve 2 is rolled up and wrapped around the outside of the limb. The two ends of the fixation sleeve 2 are connected and fixed using the fourth connecting component 9. Then, the catheter 10 is fixed with the Velcro fastening strip 21. The subsequent steps are the same as in Embodiment 1. In this embodiment, the fixation sleeve 2 can be unfolded, and only the elastic bandage 1 needs to be placed over the patient's limb, which is convenient for nursing staff to operate.
