Hanging hole one and hanging hole two are elliptical holes, and hanging hole three is a straight slot set at an angle.

[0006] Furthermore, the lubricating mechanism includes an annular sponge located in the packaging bag and sleeved on the urinary catheter, and the annular sponge is soaked with lubricant.

[0007] Furthermore, the root of the urinary catheter extends into the liquid storage cavity, and the root of the urinary catheter is connected to an anti-backflow bag.

[0008] Furthermore, the anti-backflow bag is formed by compounding two pieces of PE films, the three sides of the anti-backflow bag are heat-sealed, and the side of the anti-backflow bag close to the outlet of the urinary catheter is open.

[0009] Furthermore, the end of the urinary catheter away from the bag body is provided with a round head, and the side wall of the end of the urinary catheter is provided with a urinary catheter hole.

[0010] Furthermore, the diameter and length specifications of the catheter are adjusted according to the patient's gender. The nominal outer diameter D of the catheter satisfies 2.0mm≤D≤6.7mm, the outer diameter tolerance is ±0.33mm, and the total length L of the catheter satisfies 250mm≤L≤500mm, with an upper and lower tolerance of ±20mm.

[0011] Furthermore, a tearing opening is provided on one side of the bag body close to the urinary catheter and the hanging hole three.

[0012] Beneficial effects of the present utility model compared with the prior art: The present utility model discloses a urine drainage bag. During the process of medical staff removing the urinary catheter, the sponge with lubricant in the packaging bag lubricates the part of the urinary catheter that extends out.

SPECIFIC EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] An embodiment of the present utility model is as Figure 1 shown. A liquid storage cavity 2 is provided in the bag body 1. As a preferred embodiment of the present application, the composite film of the bag body adopts a composite material with an outer layer of PET and an inner layer of PE, which ensures the structural strength of the bag body 1 and is convenient for medical staff to tear open the tear opening of the urine drainage bag later. A urinary catheter 7 is connected to one side of the bag body 1 near the first hanging hole 4 and the third hanging hole 6. A packaging bag 8 heat-sealed to the bag body 1 is provided outside the urinary catheter 7, and a lubricating mechanism located in the packaging bag 8 is provided on the side of the urinary catheter 7 away from the bag body 1.

[0019] The surface of the bag body 1 at the position of the liquid storage chamber 2 is provided with a scale mark 3, which is convenient for medical staff to observe the liquid capacity in the catheterization bag. The bag body 1 on one side of the liquid storage chamber 2 is symmetrically provided with a hanging hole 4 and a hanging hole 2 5, and the bag body 1 on the other side is provided with a hanging hole 3 6. The hanging hole 1 4 and the hanging hole 2 5 are elliptical holes, and the hanging hole 3 6 is an inclined straight slot. The above-mentioned hanging holes are all half-cut and not pierced, which ensures the structural integrity of the product and is convenient for hanging the catheterization bag.

[0020] like Figure 2 As shown, the lubricating mechanism includes an annular sponge 10 located in a packaging bag 8 and sleeved on the urinary catheter 7. The annular sponge 10 is soaked with lubricant. Before removing the urinary catheter 7, the medical staff first tears open the end of the packaging bag 8 and grasps the annular sponge 10 in the packaging bag 8 with one hand so that the lubricant in the sponge can be smoothly applied to the surface of the urinary catheter 7, making it easier for the urinary catheter 7 to enter the patient's urethra and relieve pain.

[0021] The root of the urinary catheter 7 extends into the liquid storage chamber 2, and the root of the urinary catheter 7 is connected to an anti-backflow bag 9, which is composed of two pieces of PE film. The anti-backflow bag 9 is heat-sealed on three sides, and the side of the anti-backflow bag 9 close to the outlet of the urinary catheter 7 is conductive. During the catheterization process, urine first enters the anti-backflow bag 9 from the urinary catheter 7, and then flows into the liquid storage chamber 2 from the anti-backflow bag 9. Since the anti-backflow bag 9 is a single-sided conductive structure composed of two pieces of PE film, it can effectively prevent the urine in the liquid storage chamber 2 from flowing back.

[0022] The end of the catheter 7 away from the bag body 1 is provided with a round head, and the side wall of the end of the catheter 7 is provided with a catheter hole 12 to facilitate the smooth catheterization work. The round head structure can further reduce the pain caused by the patient's catheterization process and facilitate the catheter to enter the urethra.

[0023] The diameter and length specifications of the catheter 7 are adjusted according to the patient's gender. The nominal outer diameter D of the catheter 7 meets 2.0mm≤D≤6.7mm, the outer diameter tolerance is ±0.33mm, and the total length L of the catheter 7 meets 250mm≤L≤500mm, with an upper and lower tolerance of ±20mm. The length of the ordinary catheter 7 is 500±20mm and is used for male patients. The length of the female catheter 7 is 250±20mm. Catheters 7 of different lengths and thicknesses are selected according to actual conditions.

[0024] A tearing opening 11 is provided on one side of the bag body 1 close to the catheter 7 and the hanging hole 3 6, so that urine can be taken out for testing by tearing the tearing opening 11 after the catheterization is completed.

[0025] The following points need to be noted: First, in the description of this application, it should be noted that unless otherwise specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense, which can be a mechanical connection or an electrical connection, or the communication inside two components, and can be directly connected.
