Urinary catheter
A urinary catheter and container are described. The urinary catheter may have a catheter shaft attached to a handle, and a coating disposed on an outer surface of the catheter shaft. The coating may include a hydrogel, water and/or glycerin, and a polyethylene glycol (PEG). The PEG may have a molecular weight equal to or less than 600, for example one or more of polyethylene glycol (PEG) 300 and PEG 400. The coating may be applied in a wet state and remain wet for an extended period of time in the container, thereby obviating the need for a lubricant, such as a water sachet or gel package, to accompany the catheter in the container. The container may include a gas impermeable foil material. The container may include an adhesive tab covering a perforated section, the adhesive tab including a pull loop.
1. A urinary catheter, comprising:
a handle including:
a plurality of ridges designed for gripping the handle; and
one or more loops integral with the handle designed for manipulating the urinary catheter; and
a catheter shaft attached to the handle, the catheter shaft including:
a catheter tip;
a lumen; and
a plurality of eyelets proximate the catheter tip, the plurality of eyelets in fluid communication with an opening in a proximal end of the handle by way of the lumen.
2. The urinary catheter according to claim 1 , wherein a first plane including a transverse cross-section of the handle is orthogonal to a second plane including at least one opening of the one or more loops.
3. The urinary catheter according to claim 1 , wherein the handle is configured to rest in a hand of a patient or a caregiver while the one or more loops respectively receive one or more fingers of the patient or the caregiver.
4. The urinary catheter according to claim 1 , wherein the one or more loops are respectively one or more rings, each attached to the handle by a tab extension of the handle.
5. The urinary catheter according to claim 1 , wherein the plurality of eyelets include at least two pairs of staggered eyelets staggered along a length of the catheter shaft and offset by about 90 degrees around the catheter shaft in a non-overlapping configuration.
6. The urinary catheter according to claim 1 , further comprising:
a hydrophilic base coating over the catheter shaft, a base coating of polyacrylic acid (PAA) in a range of 0.2 wt % to 3 wt %, glycerin in a range of 15 wt % to 25 wt %, water in a range of 20 wt % to 30 wt %, and polyethylene glycol (PEG) 400 in a range of 40 wt % to 60 wt %.
7. The urinary catheter according to claim 1 , further comprising:
a hydrophilic base coating over the catheter shaft, a base coating of polyacrylic acid (PAA) in a range of 0.1 wt % to 2.5 wt %, water in a range of 10 wt % to 45 wt %, and polyethylene glycol (PEG) in a range of 20 wt % to 65 wt %.
8. The urinary catheter according to claim 1 , further comprising:
a hygroscopic outer coating over the catheter shaft, an outer coating of a hydrogel in a range of 20 wt % to 30 wt %, glycerin in a range of 20 wt % to 30 wt %, and polyethylene glycol (PEG) 400 in a range of 40 wt % to 60 wt %.
9. The urinary catheter according to claim 1 , further comprising:
a hygroscopic outer coating over the catheter shaft, an outer coating of a hydrogel in a range of 20 wt % to 30 wt %, glycerin in a range of 40 wt % to 60 wt %, and polyethylene glycol (PEG) 300 in a range of 20 wt % to 30 wt %.
10. The urinary catheter according to claim 1 , further comprising:
a hygroscopic outer coating over the catheter shaft, an outer coating of a hydrogel in a range of 10 wt % to 35 wt %, glycerin in a range of 25 wt % to 75 wt %, polyethylene glycol (PEG) 300 in a range of 25 wt % to 65 wt %, and PEG 400 in a range of 25 wt % to 50 wt %.
11. The urinary catheter according to claim 1 , further comprising:
a hygroscopic outer coating over the catheter shaft, an outer coating of a hydrogel in a range of 15 wt % to 35 wt %, water in a range of 10 wt % to 45 wt %, and polyethylene glycol (PEG) 400 in a range of 20 wt % to 75 wt %.
12. The urinary catheter according to claim 1 , further comprising:
a hygroscopic outer coating over the catheter shaft, an outer coating of a hydrogel in a range of 22 wt % to 26 wt %, water at approximately 25 wt %, and polyethylene glycol (PEG) 400 is in a range of 49 wt % to 53 wt %.
