[0021] The drawings in the present invention are not drawn strictly according to the actual scale, and the specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only schematic diagrams of the structures.

[0022] The disposable male portable urinal provided by the present invention is as follows Figure 1-Figure 2 , Figure 7-Figure 8 and Figure 12-13 The invention comprises a sealed liquid storage bag 1, which is flat so that the liquid storage bag 1 has two bag films, one above and one below. The two bag films on the liquid storage bag 1 are attached to each other. The disposable male portable urinal also comprises: a urinary catheter 2, one end of which is located inside the liquid storage bag 1 and the other end of which is located outside the liquid storage bag 1 and serves as an inlet for urine. The part of the urinary catheter 2 located inside the liquid storage bag 1 is connected to the two bag films; two adhesive parts 3, which are respectively connected to the two ends of the liquid storage bag 1, and the two adhesive parts 3 are respectively attached to the left and right thighs to confine the liquid storage bag 1 between the left and right thighs.

[0023] The bag body thickness of the liquid storage bag 1 is 0.5mm-1.5mm, the diameter of the catheter 2 is 3cm-5cm, the length of the adhesive part 3 is 20cm, the width is 3cm, the adhesive part 3 is Velcro, and the two adhesive parts 3 are used to be attached to the left and right thighs respectively, and are used to properly prop up the liquid storage bag 1, which is convenient for the patient to lie on the bed or sit or lie in the car. The liquid storage bag 1 is lowered away from the inlet end of the catheter 2, and the patient urinates toward the inside of the inlet end of the catheter 2. The urine flows into the liquid storage bag 1 along the catheter 2 for storage. The liquid storage bag 1 falls due to the gravity of the urine, and the user reduces the opening and closing degree of the legs by controlling to lower the height of the liquid storage bag 1 and place it for collection.

[0024] This disposable male portable urinal is suitable for men lying in bed or sitting in a car. It is easy to operate, hygienic and safe. It can be used without significantly changing the patient's lying posture or the passenger's sitting posture. It can also be used in a small space, which greatly facilitates patients and passengers and can solve the problem of men having nowhere to urinate or being inconvenient to urinate in an emergency.

[0025] In this embodiment, Figure 1 The urinary catheter 2 is provided with a plurality of channels 4 for urine to flow toward the two sides of the liquid storage bag 1 , and both sides of the liquid storage bag 1 are filled with granular materials for absorbing urine.

[0026] The urine in the catheter 2 enters the left and right sides of the liquid storage bag 1 through multiple channels 4. The catheter 2 here is preferably a hose, such as a rubber tube, for the purpose of better folding and storage, so that it occupies less space and is easy to carry and store. The particles are polymer absorbent resins. The urine in the liquid storage bag 1 contacts the particles. The particles expand after absorbing the urine. The expanded particles open the liquid storage bag 1, so that more particles can contact the urine and absorb more urine; at the same time, in the process of the expanded particles opening the liquid storage bag 1, the space in the liquid storage bag 1 increases to generate negative pressure, which is more conducive to the urine in the catheter 2 flowing into the liquid storage bag 1, and can prevent the urine from shaking and backflowing in the liquid storage bag 1. The particles are similar to the granular components in diapers that absorb urine and have similar effects.

[0027] In this embodiment, Figure 3-Figure 4 Each of the channels 4 includes: an arc-shaped pipe 5, which is fixedly connected to the outer periphery of the catheter 2, and the middle part of the arc-shaped pipe 5 is connected to the catheter 2 through a catheter hole 6; two hoses 7, which are respectively arranged at the two ends inside the liquid storage bag 1, one end of each hose 7 is connected to the end of the arc-shaped pipe 5, and the other end is used to guide urine toward the particles in the liquid storage bag 1.

[0028] The diameters of the arc-shaped pipe 5 and the hose 7 are both 0.5cm-1cm. The urine in the urinary catheter 2 flows into the arc-shaped pipe 5 through the urinary catheter hole 6, and then flows into the hose 7 through both ends of the arc-shaped pipe 5, and enters the liquid storage bag 1 through the hose 7.

[0029] In this embodiment, Figure 3-Figure 5 Both ends of the liquid storage bag 1 are provided with storage bags 7 for easy urine penetration, and the granular matter is filled in the storage bags 7. The end of each storage bag 7 away from the catheter 2 is connected with a tension rope 8, and the tension rope 8 passes through the perforation on the liquid storage bag 1 to connect to the adhesive part 3.

[0030] The storage bag 7 is made of a water-permeable non-woven fabric or a mesh bag, and particles are wrapped inside the storage bag 7 to prevent some particles from gathering in the corners of the liquid storage bag 1, resulting in the problem of insufficient absorption of urine. In the process of opening the legs, the tension rope 8 pulls the storage bag 7 to move in the direction away from the catheter 2, which can not only open the liquid storage bag 1, but also open the space inside the liquid storage bag 1, producing a better siphon effect, so that more urine passes through the storage bag 7 and is absorbed by the particles. The expansion of the particles after absorbing urine is also conducive to opening the space inside the liquid storage bag 1. The two promote each other and produce better beneficial effects.

[0031] In this embodiment, Figure 3-Figure 5The storage bag 7 is fixedly connected to the outside of the catheter 2 away from the fixing plate 9, the length direction of the fixing plate 9 is parallel to the length direction of the catheter 2, the fixing plate 9 is connected to the tension rope 8, the number of the tension ropes 8 is multiple (the number of tension ropes 8 on each side is preferably three), and the multiple tension ropes 8 are arranged parallel to each other.

[0032] The length of the fixing plate 9 is 10 cm, the thickness is 3 mm, and the width is 7 mm. The purpose is to enable the storage bag 7 to translate as a whole, so that the storage bag 7 is evenly subjected to tension. Under the condition of pulling at the same speed and with the same force, it can create a larger expansion space, thereby producing a better siphon effect and improving the absorption efficiency of urine.

[0033] In this embodiment, Figure 5 The side of the storage bag 7 close to the urinary catheter 2 is provided with a plurality of through holes 10 for allowing urine to enter the storage bag 7 .

[0034] The purpose is that urine can enter the storage bag 7 through the through hole 10 and fully contact with the urine without generating a siphon effect.

The transparent film is embedded in the side wall of the bag body of the liquid storage bag 1, and the test strip is pasted on the inner surface of the transparent film.

[0036] When urine enters the liquid storage bag 1, the urine contacts the test strip and changes color. The amount of urine in the liquid storage bag 1 can be judged by the length of the color change on the color strip 11, which is convenient for the user to observe and replace it in time after absorbing enough urine.

[0037] In this embodiment, Figure 1 , Figure 6 and Fig. 9 A trumpet-shaped urine inlet 12 is provided at the inlet end of the urinary catheter 2 , and a shielding layer 13 for protecting privacy is connected to the liquid storage bag 1 near the urine inlet 12 .

[0038] The urine inlet 12 has a large end and a small end. The diameter of the large end of the urine inlet 12 is 8cm-10cm. The small end is connected to the inner wall of the end of the catheter 2 through a thread, and the large end serves as the entrance end of new urine. The shielding layer 13 is an opaque soft sheet material, such as a plastic layer. When in use, the shielding layer 13 is used to shield private parts, which can better protect the privacy of the user.

[0039] In this embodiment, Figure 1 , Figure 6 and Fig. 9 The shielding layer 13 is provided with a slide rail, and the outer wall of the urine inlet 12 is provided with a slider, and the slider is slidably matched with the slide rail. The urine inlet 12 is connected to the urinary catheter 2 via a telescopic tube 14 .

[0040] The large end of the urine inlet 12 has a flat side wall, on which there is a slider for sliding with the slide rail. Both ends of the telescopic tube 14 are connected to the urine inlet 12 and the catheter 2 by threads, wherein the outer periphery of the urine inlet 12 has a handle, and the user pulls the handle to move the urine inlet 12 along the slide rail to a suitable position, and during the process, the telescopic tube 14 is adaptively telescoped.

[0041] In this embodiment, Figure 9-11 The shielding layer 13 , the liquid storage bag 1 and the adhesive portion 3 can all be rolled up on the outside of the urinary catheter 2 at the same time to form a roll 15 that is easy to store. A roll cover 14 is provided on the end of the roll 15 close to the urine inlet 12 .

[0042] The diameter of the roll cover 14 is 9.5cm-11.5cm. The roll cover 14 has a receiving groove for receiving the handle on the urine inlet 12. The roll cover 14 is covered on the roll 15 to prevent the liquid storage bag 1 from spreading. At the same time, the receiving groove can also prevent the roll cover 14 and the cylindrical liquid storage bag 1 from twisting. The roll cover 14 also has the function of preventing odor from wafting.

[0043] The method of using the disposable male portable urinal includes the following steps: S100, the user selects a suitable lying position or sitting position, and sticks the two adhesive parts 3 on the left and right thighs respectively, so as to properly prop up the liquid storage bag 1 and lower the liquid storage bag 1 away from the inlet end of the urinary catheter 2; S200, the patient urinates toward the inside of the entrance end of the urinary catheter 2, the urine enters the urinary catheter 2, and enters the left and right sides of the liquid storage bag 1 through the multiple channels 4, the urine in the liquid storage bag 1 passes through the storage bag 7, and contacts with the particles in the storage bag 7, the particles absorb the urine and expand to open the liquid storage bag 1, and a siphon effect is generated, so that more urine in the liquid storage bag 1 contacts with the particles; S300, the legs are opened, driving the tension ropes 8 on both sides to move away from each other, and the tension ropes 8 pull the storage bag 7 to move away from the urinary catheter 2, which can open up the space in the liquid storage bag 1 and enhance the siphon effect; S400, after finishing urinating, take off the tension rope 8 on the leg and remove the liquid storage bag 1.

[0044] During the process of opening the legs, the tension rope 8 pulls the storage bag 7 to move in the direction away from the catheter 2, which can not only open the liquid storage bag 1, but also open the space inside the liquid storage bag 1, producing a better siphon effect, so that more urine passes through the storage bag 7 and is absorbed by the particles. The expansion of the particles after absorbing urine is also conducive to opening the space inside the liquid storage bag 1. The two promote each other and produce better beneficial effects.
