[0016] The principle and beneficial effects of the technical solution are:

[0017] 1. The present invention provides a portable urine collection device for geriatrics. The urine receiver is used to collect urine discharged by elderly patients. The urinary catheter connects the urine receiver with the urine collection bag, so that the urine collection bag can effectively collect urine discharged by the elderly patients. A fixing part, an anti-odor component and an anti-backflow component are connected on a base plate. The fixing part fixes the urine collection bag on the patient's legs or bed frame, etc., so as to facilitate the use of the entire urine collection device and improve the convenience of the entire urine collection device. The anti-odor component mixes the deodorant liquid in the deodorant liquid bottle with urine to reduce the smell of urine. The anti-backflow component cleans the urine attached to the side wall of the urinary catheter into the urine collection bag to avoid urine backflow.

[0018] 2. The present invention provides a portable urine collecting device for geriatrics. The deodorant liquid bottle containing deodorant liquid is a press-discharge bottle body. The deodorant liquid in the bottle body is guided to the urine collecting bag through the liquid guide tube by pressing, so that the deodorant liquid is mixed with the urine in the urine collecting bag. The liquid outlet end of the liquid guide tube is arranged at the upper half of the urine collecting bag, which can effectively avoid the direct contact between the liquid guide tube and the urine, and the deodorant liquid flows into the urine collecting bag from top to bottom, which can improve the mixing effect between the deodorant liquid and the urine; the anti-backflow component includes an air bag, a spring and a pressing piece. The pressing plate is pressed downward. This process will overcome the force of the spring to squeeze the air bag, so that a part of the gas in the air bag enters the urine collecting bag through the first air guide tube, so that the deodorant liquid and urine in the urine collecting bag are pneumatically stirred under the action of the gas, thereby increasing the degree of mixing between the deodorant liquid and the urine, and improving The air bag has a high deodorizing effect. Another part of the gas in the air bag enters the urinary catheter through the second air duct to "blow" the side wall of the urinary catheter. The length or straightening state of the urinary catheter is adjusted and / or controlled to avoid urine being discharged from the urine receiver along the side wall of the urinary catheter during the "blowing" process. Instead, the urine enters the urine collecting bag along the side wall of the urinary catheter, thereby cleaning the urine attached to the side wall of the urinary catheter. When the pressing action on the pressing plate is cancelled, the air bag returns to its original state under the action of the spring and the air inlet valve to facilitate a second pressing operation. In the process of returning to its original state, the air bag also produces an "inhalation" action in the urinary catheter, so that the urine attached to the side wall of the urinary catheter is cleaned into the urine collecting bag under the action of atmospheric pressure, and the side wall of the urinary catheter is cleaned for a second time to avoid the backflow of attached urine.

[0019] 3. The present invention provides a portable urine collecting device for geriatrics, in which a blank portion is arranged in the middle of the airbag, and a spring is arranged inside the blank portion, and a guide column is arranged inside the spring to guide and limit the movement of the spring and / or the airbag, so that the movement process of the airbag is uniform and stable, so as to improve the functionality of pneumatic stirring and backflow prevention; the pressing piece is fixedly connected to the pressing part of the deodorant liquid bottle, and by pressing the pressing piece once, the deodorant liquid can be added to the urine collecting bag and the airbag can be pressed at the same time, so that the deodorization and backflow prevention operations are combined into one, further improving the convenience of operation; and the first air duct is arranged in the lower half of the urine collecting bag, so that the gas discharged from the first air duct can fully act on the urine and the deodorant liquid, further improving the pneumatic stirring effect on the mixed solution.

[0020] 4. The present invention provides a portable urine collection device for geriatrics. A first gas one-way valve is connected to the first air duct to control the one-way movement of gas from the air bag to the urine collection bag. This can not only ensure the functionality of pneumatic stirring, but also prevent the solution (deodorant and / or urine) in the urine collection bag from flowing back in the first air duct. A second gas one-way valve is connected to the second air duct to control the one-way movement of gas from the urinary catheter to the air bag. When the air bag is squeezed, the gas cannot enter the urinary catheter and all enters the urine collection bag for pneumatic stirring. During the recovery process of the air bag, the inner side of the urinary catheter has an "inhalation" effect, which reduces the air pressure in the urinary catheter. Under the action of atmospheric pressure, the urine attached to the side wall of the urinary catheter is cleaned into the urine collection bag, and the side wall of the urinary catheter is cleaned to prevent the attached urine from flowing back. The fixing part is a strap, which has a good fixing effect on the urine collection bag.

[0021] 5. The portable urine collection device for geriatrics provided by the present invention is connected to the first air duct to control the one-way movement of gas from the air bag to the urine collection bag, which can not only ensure the functionality of pneumatic stirring, but also prevent the solution (deodorant and / or urine) in the urine collection bag from flowing back in the first air duct; the second air duct is connected to the second air duct to control the one-way movement of gas from the air bag to the catheter. When the air bag is squeezed, the gas enters the catheter to "blow" its side wall. By adjusting and / or controlling the length or straightening state of the catheter, urine is prevented from being discharged from the urine receiver along the side wall of the catheter during the "blowing" process, so that it enters the urine collection bag along the side wall of the catheter, and the urine attached to the side wall of the catheter is cleaned. During the recovery process of the air bag, urine attached to the side wall of the catheter is prevented from entering the inner side of the air bag along the second air duct, so as to reduce the dispersion area of ​​urine and reduce odor. The fixing part is a hook, which is simple and quick to fix the urine collection bag.

[0022] 6. The present invention provides a portable urine collection device for geriatrics, in which the urine receiver is conical, and the end of the urine receiver connected to the guide tube is the small end. The urine receiver is also fixed with a handle, so that it can be suitable for male or female elderly patients, and the handle makes the use process more convenient; the urinary catheter is connected to a liquid one-way valve that controls the unidirectional movement of urine from the urine receiver to one side of the urine collection bag, so as to avoid backflow in the urinary catheter during pouring and / or moving.
