Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bladder training aid device. Background Technology

[0002] The urinary catheter currently in use requires the flow-stopping clamp on the external drainage tube to be closed periodically to stop the flow and train the function of the bladder detrusor muscle. If the flow-stopping clamp is not closed, urine will continue to flow out, and the bladder will not experience the process of urine filling, so the function of the bladder detrusor muscle may not be maintained normally.

[0003] While traditional catheters with stop-flow clips can help train the bladder detrusor muscle, when the bladder volume is too high and the pressure reaches the discharge threshold, the stop-flow clip still needs to be manually opened. This requires medical staff or caregivers to regularly observe whether the urine volume has reached the discharge threshold, increasing the complexity and workload of nursing care. Furthermore, the over-reliance on manual intervention often leads to caregivers forgetting to observe or discharge urine, which can easily cause urinary tract infections in patients. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive bladder training aid that effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A bladder training aid includes a urinary catheter with a rectangular box connected to its tail end. A partition is fixed inside the rectangular box, and a bottom cavity is located below the partition. The partition has a vertically penetrating flow port. Two symmetrically arranged arc-shaped sealing plates, both extending downward into the bottom cavity, are hinged to the flow port. The protrusions of the two arc-shaped sealing plates abut against each other to achieve a seal. Mounting seats are provided on the inner walls of the rectangular box below the partition. Mounting rods are fixed on the surfaces of the two mounting seats that are close to each other. Miniature springs are horizontally mounted on the two mounting rods, and the two miniature springs are connected to the back of the arc-shaped sealing plates one by one.

[0007] Therefore, when the urine in the bladder reaches a certain amount, and the pressure of the urine in the bladder and urethra is greater than the combined force of the two miniature springs, the two arc-shaped sealing plates can be pushed open and the miniature springs can be compressed. At this time, the protruding parts of the two arc-shaped sealing plates will separate, and the urine can pass through and be discharged between the two arc-shaped sealing plates, realizing the adaptive discharge of urine. Even when unattended, it can automatically discharge when there is an excess of urine in the bladder, avoiding causing urinary tract infections in patients.

[0008] Furthermore, both arc-shaped sealing plates have a flat portion at their contact points, and a sealing gasket is fixed to the surface of each flat portion, with the two sealing gaskets abutting and adhering to each other.

[0009] Furthermore, both sides of the rectangular box are provided with horizontally penetrating sliding holes, and guide rods are slidably inserted into both sliding holes. The outer wall of the guide rod and the inner wall of the sliding hole are slidably sealed together. Two mounting seats are fixed one-to-one on the ends of the guide rods located in the bottom cavity. An adjustment mechanism is provided on the outer surface of the rectangular box. The adjustment mechanism is used to drive the two guide rods to move closer or further apart.

[0010] Furthermore, the adjustment mechanism includes a bracket fixed to the outer surface of the rectangular box, a bidirectional threaded rod rotatably mounted on the bracket, two nut seats threadedly fitted onto the bidirectional threaded rod on both sides, and connecting arms fixed to the nut seats respectively. The ends of the two connecting arms are fixedly connected to the outer ends of the two guide rods one by one, and a handle is installed at one end of the bidirectional threaded rod.

[0011] Furthermore, the rectangular box contains a monitoring chamber located above the partition. A pressure sensor is fixed on the side wall of the rectangular box, and the detection end of the pressure sensor extends into the monitoring chamber. A wireless signal transmitting module that is connected and matched with the wireless receiver signal on the monitor is fixed on the outer surface of the urine catheter. The wireless signal transmitting module is electrically connected to the pressure sensor.

[0012] Furthermore, an air bladder is provided on the outer wall of the urinary catheter near its head, and an interface that can be matched and connected to a urine drainage bag is provided at the tail end of the urinary catheter.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This invention utilizes the elastic support of two miniature springs to push the protruding parts of two arc-shaped sealing plates to abut against each other, thereby achieving a seal and preventing the indiscriminate discharge of urine from the patient's bladder. This achieves the effect of training the bladder detrusor muscle. When the urine in the bladder reaches a certain amount, and the urine pressure in the bladder and ureter exceeds the combined force of the two miniature springs, the two arc-shaped sealing plates can be pushed open, and the miniature springs can be compressed. At this time, the protruding parts of the two arc-shaped sealing plates will separate, and urine can pass through and be discharged between the two arc-shaped sealing plates, achieving adaptive discharge of urine. Even when unattended, it can automatically discharge urine when there is an excess in the bladder, avoiding urinary tract infections in patients.

[0015] 2. The two arc-shaped sealing plates in this utility model can increase the contact area when the two arc-shaped sealing plates are closed by plane contact at the flat part, so as to ensure the sealing effect. In addition, sealing gaskets are fixed on the surface of the two flat parts. The two sealing gaskets abut against each other and are attached to each other. The sealing effect of the two arc-shaped sealing plates is further increased by the abutment of the two sealing gaskets, so as to avoid the leakage of urine and thus improve the training effect of the bladder detrusor muscle.

[0016] 3. This utility model adjusts the elongation of the two miniature springs by moving the two guide rods closer or further apart through the operating adjustment mechanism. This, in turn, adjusts the urine pressure required to open the two arc-shaped sealing plates, so as to exercise the patient's bladder detrusor muscle to different degrees, meet the actual use needs, and has high versatility.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a bladder training aid device, including a urinary catheter 1. An air bladder 11 is provided on the outer wall of the urinary catheter 1 near its head. An interface 12 that can be matched and connected to a urine drainage bag is connected to the tail end of the urinary catheter 1. When in use, the head and air bladder 11 of the urinary catheter 1 are placed in the patient's bladder, and the tail end of the urinary catheter 1 is led out of the patient's body. The air bladder 11 is used to ensure that the head of the urinary catheter 1 will not fall out of the bladder when the patient's body position changes. The interface 12 is used to connect the urinary catheter 1 to the urine drainage bag, so that the urine in the patient's bladder can be drained into the urine drainage bag through the urinary catheter 1, so as to realize the patient's urine discharge.

[0024] A rectangular box 2 is connected to the end of the urinary catheter 1. A partition 3 is fixed inside the rectangular box 2. Below the partition 3 is a bottom cavity 32 within the rectangular box 2. The partition 3 has a vertically penetrating flow port 31. Two symmetrically arranged arc-shaped sealing plates 4, both extending downwards into the bottom cavity 32, are hinged within the flow port 31. The protrusions of the two arc-shaped sealing plates 4 abut against each other. Mounting seats 5 are located on the inner walls of the rectangular box 2 below the partition 3. Mounting rods 51 are fixed to the surfaces of the two mounting seats 5 that are close to each other. Miniature springs 52 are horizontally mounted on each of the two mounting rods 51. The two miniature springs 52 are connected to the back of the arc-shaped sealing plates 4 one-to-one. The elastic support of the two miniature springs 52 can push the protrusions of the two arc-shaped sealing plates 4 to abut against each other, thereby achieving a seal and preventing the urine in the patient's bladder from being discharged at will. This achieves the effect of training the bladder detrusor muscle. When the urine in the bladder is stored to a certain amount, and the urine pressure in the bladder and ureter 1 is greater than the resultant force of the two miniature springs 52, the two arc-shaped sealing plates 4 can be pushed open and the miniature springs 52 can be compressed. At this time, the protrusions of the two arc-shaped sealing plates 4 will separate, and the urine can pass through and be discharged between the two arc-shaped sealing plates 4, realizing the adaptive discharge of urine. Even when unattended, it can automatically discharge when there is an excess of urine in the bladder, avoiding causing urinary tract infection in the patient.

[0025] Specifically, each of the two arc-shaped sealing plates 4 has a flat portion 41 at the point where they abut against each other. The two arc-shaped sealing plates 4 make contact through the flat portion 41, which increases the contact area when the two arc-shaped sealing plates 4 are closed, ensuring the sealing effect. In addition, a sealing gasket 42 is fixed on the surface of each of the two flat portions 41. The two sealing gaskets 42 abut against each other and adhere to each other. The abutment of the two sealing gaskets 42 further increases the sealing effect of the two arc-shaped sealing plates 4, preventing urine leakage and thus improving the training effect of the bladder detrusor muscle.

[0026] Specifically, both sides of the rectangular box 2 are provided with horizontally penetrating sliding holes 501. Guide rods 502 are slidably inserted into both sliding holes 501. The outer wall of the guide rod 502 and the inner wall of the sliding hole 501 are slidably sealed together. Two mounting seats 5 are fixed one-to-one on the ends of the guide rods 502 located in the bottom cavity 32. An adjustment mechanism 6 is provided on the outer surface of the rectangular box 2. The adjustment mechanism 6 is used to drive the two guide rods 502 to move closer or further apart. By operating the adjustment mechanism 6 to drive the two guide rods 502 to move closer or further apart, the extension of the two micro springs 52 can be adjusted, thereby adjusting the urine pressure required to open the two arc-shaped sealing plates 4, so as to exercise the patient's bladder detrusor muscle to different degrees, meet the actual use needs, and have high versatility.

[0027] In addition, when the operating adjustment mechanism 6 drives the two guide rods 502 to move away from each other to their extreme positions, the two arc-shaped sealing plates 4 can be separated from each other under the connecting action of the micro spring 52, ensuring that the entire discharge path is in a passable state, which facilitates the emptying of urine from the patient's bladder.

[0028] Specifically, the adjustment mechanism 6 includes a bracket 61 fixed to the outer surface of the rectangular box 2, a bidirectional threaded rod 62 rotatably mounted on the bracket 61, two nut seats 63 threadedly fitted onto the bidirectional threaded rod 62 on both sides, and connecting arms 64 respectively fixed on the nut seats 63. The ends of the two connecting arms 64 are fixedly connected to the outer ends of the two guide rods 502 one by one. A handle 621 is installed at one end of the bidirectional threaded rod 62. By squeezing the handle 621, the bidirectional threaded rod 62 can be screwed and adjusted. The rotating bidirectional threaded rod 62 can drive the two nut seats 63 to move closer or further apart. Under the connection of the connecting arms 64, the guide rods 502 move synchronously, providing a drive for the position adjustment of the two sliding holes 501.

[0029] Specifically, the rectangular box 2 contains a monitoring chamber 33 located above the partition 3. A pressure sensor 7 is fixed on the side wall of the rectangular box 2, and the detection end of the pressure sensor 7 extends into the monitoring chamber 33. A wireless signal transmission module 71, which is connected and matched with the wireless receiver signal on the monitor, is fixed on the outer surface of the urinary catheter 1. The wireless signal transmission module 71 is electrically connected to the pressure sensor 7. The pressure sensor 7 can be used to monitor the urine pressure, and the monitoring data is transmitted to the monitor via the wireless signal transmission module 71. In case of abnormality, the monitor can automatically alarm, thus realizing the function of monitoring the amount of urine in the patient's bladder.

[0030] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
