Description

Technical Field

[0001] The present application relates to the field of drainage devices, and in particular to a drainage device with a bladder detrusor muscle training function. Background Art

[0002] A urinary catheter is a tube that is inserted from the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) that can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from coming out. The drainage tube is connected to a urine bag to collect urine. Since the catheter is inserted into the bladder for a long time, urine can flow directly out of the catheter without the need to exert force on the detrusor muscle. Such a long time will cause the detrusor muscle to relax and lose its normal function. After the catheter is pulled out, urination becomes difficult or even incontinence occurs.

[0003] At present, in clinical practice, a common method is to block the urinary catheter with a flow clamp, so that the bladder is filled, and after a period of filling, urine retention occurs, allowing the detrusor muscle to function normally; however, the flow clamp can only completely close and open the urinary catheter; thus, after the bladder is filled, opening the flow clamp will cause rapid urination, and the bladder will lose pressure in a short period of time, resulting in secondary injury to the bladder after surgery;

[0004] There is no drainage device capable of regulating the urination flow rate and exercising the bladder detrusor muscle function. Summary of the invention

[0008] The deformable membrane is installed on the inner wall of the communication cavity and has a deformable cavity communicated with the communication cavity;

[0009] Two sliding rods are arranged on the connecting piece opposite to each other and inserted into the connecting cavity;

[0010] A limit block, movably arranged on the connecting piece;

[0011] The connecting piece is fixedly arranged at one end of the urinary catheter away from the bladder beside the human body; the outer wall of the connecting piece forms a guide groove for guiding the two slide bars to approach / move away from the deformation membrane along the diameter direction of the connecting piece; the side wall of the slide bar forms a limiting portion that abuts against the limiting block; the limiting block is arranged on the inner wall of the guide groove and moves along the diameter direction of the guide groove to give the slide bar an upper limit in the guiding direction of the guide groove, so as to adjust the distance between the two slide bars;

[0012] During use, the two slide bars resist each other against the deformable membrane, so that the bladder cannot urinate through the connecting cavity, thereby simulating the effect of normal people holding urine; at this time, the detrusor muscle is in an expanded state; when urination is needed, the movement of the slide bar is limited by the limit rod to adjust the flow of urine through the connecting cavity; at this time, the detrusor muscle begins to contract when urination begins; since the urination flow rate is controlled, the detrusor muscle is always in a state of exertion; in this way, normal people's urination can be simulated, which is beneficial for patients to simulate normal urination when they are unable to urinate normally so as to exercise the recovery of detrusor muscle function.

[0013] In some embodiments, one end of the two sliding rods close to the deformable membrane forms an interference portion that interferes with the deformation of the deformable membrane to adjust the flow of the medium flowing through the deformation cavity.

[0014] In some embodiments, the drainage device with bladder detrusor training function further comprises:

[0015] A first electromagnet is mounted on the connecting piece;

[0016] A first magnetic member is fixedly disposed on the slide bar relative to the first electromagnet;

[0026] An adjusting rod is movably arranged in the hydraulic cavity and is threadably connected to the knob;

[0027] A perforation is arranged in the hydraulic cavity to guide the adjusting rod away from or close to the valve.

[0028] In some embodiments, the inner wall of the guide groove forms a slide groove that guides the limit block to approach / move away from the slide bar;

[0029] The limiting block is connected to the inner wall of the sliding groove through the second elastic member, and the second elastic member gives the limiting block an elastic force to always keep it away from the sliding rod.

[0030] In some embodiments, the drainage device with bladder detrusor training function further comprises:

[0031] A second electromagnet is disposed on the connecting member and is corresponding to the guide groove;

[0032] A second magnetic member is disposed on the limiting block;

[0033] A limiting rod is movably arranged on the connecting piece along the extending direction of the guide groove;

[0034] The flow detector is arranged on the connecting piece.

[0035] In some embodiments, a rubber tube is also provided on the inner wall of the communication cavity;

[0036] The inner wall of the hose and the inner wall of the deformation membrane are arranged coplanarly;

[0037] The inner wall of the rubber hose forms a through hole communicating with the hydraulic chamber.

[0038] In some embodiments, a central processor is installed in the connector, and the central processor is electrically connected to the flow detector;

[0039] The central processing unit is electrically connected to the first electromagnet / the second electromagnet.

[0040] The beneficial effects of the present application are as follows: 1. Under the action of the two slide bars resisting each other against the deformable membrane, the bladder cannot urinate through the connecting cavity, thus achieving the effect of simulating a normal person holding urine; the movement of the slide bar is limited by the limit rod to adjust the flow rate of urine flowing through the connecting cavity; at this time, the detrusor muscle begins to contract when urination begins; since the urination flow rate is controlled, the detrusor muscle is always in a state of exertion; in this way, normal urination can be simulated, which is beneficial for patients to simulate normal urination when they are unable to urinate normally to exercise the detrusor muscle function recovery;

[0041] Second, by providing the first electromagnet and the first magnetic member, the sliding rod can be automatically driven to move, thereby automatically urinating and holding urine without human intervention;

[0042] 3. The pressure detector can be set to enable the first electromagnet to automatically urinate according to the pressure in the bladder;

[0043] 4. By setting up a flow detector, the flow rate of each urination can be controlled and adjusted according to the rehabilitation needs of different patients; it can also accurately detect urine volume. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] More specifically, the connector 4 is provided with a pressure detection assembly 18 for detecting the hydraulic pressure in the bladder. The pressure detection assembly 18 includes a sensor 23 electrically connected to the first electromagnet 15. When the sensor 23 senses that the pressure in the bladder reaches a set value, the first electromagnet 15 is powered off, and urination begins.

[0072] In an optional solution, the inner wall of the guide groove 10 forms a slide groove that guides the limit block to approach / move away from the slide rod 8. The limit block is connected to the inner wall of the slide groove through a second elastic member. The second elastic member gives the limit block an elastic force to always keep it away from the slide rod 8. Therefore, in the initial state, the two slide rods 8 can completely block the deformation cavity 7 without any limit block.

[0073] In a more specific optional embodiment, the drainage device 100 with bladder detrusor training function further includes: a second electromagnet 31, a second magnetic member 32, and a flow detector 34; wherein the second electromagnet 31 is disposed on the connecting member 4 and is disposed corresponding to the guide groove 10; the first to third limit blocks are all provided with a second magnetic member 32 corresponding to the second electromagnet 31, and the second magnetic member 32 is a permanent magnet, and the second electromagnet 31 can drive the permanent magnet to move toward the slide bar 8 after being energized; specifically, a flow detector 34 for detecting the flow of the urinary tube 2 is disposed on the connecting member 4, and the flow detector 34 is located on the inner wall of the connecting cavity 5 between the urinary tube 2 and the slide bar 8;

[0075] In another typical embodiment, the urine flow rate of patients with urinary retention shall not exceed 500 ml each time, and the program can be input into the central processing unit; when the flow detector 34 detects that the urine flow rate has reached 500 ml, the electrical signal is transmitted to the actuator, and the actuator controls the first electromagnet 15 to be energized to stop urination.

[0076] In another typical embodiment, the second electromagnet 31 corresponding to the first limit block 12, the second limit block 13 and the third limit block 14 is connected in parallel with the actuator, and the actuator can drive the first limit block 12, the second limit block 13 and the third limit block 14 to move respectively; when the patient performs bladder detrusor exercise, the second electromagnet 31 is energized so that the three limit blocks all protrude from the inner wall of the guide groove 10; when the pressure in the bladder reaches the rated value, the actuator drives the first electromagnet 15 to cut off the power and the slide bar 8 is reset; at this time, the limit portion 11 first conflicts with the first limit block 12; then the actuator controls the first limit block 12, the second limit block 13 and the third limit block 14 to reset in sequence; in this way, the urination flow rate is increased from slow to fast. After the slide bar 8 is completely reset, the three limit blocks move into the guide groove 10 again; similarly, if urination needs to be stopped during urination, the actuator energizes the first electromagnet 15 to drive the slide bar 8 to contact the deformation membrane 6; at this time, the third limit block 14 first contacts the limit portion 11, and then the actuator controls the third limit block 14, the second limit block 13 and the first limit block 12 to reset in sequence, thereby achieving the goal that the urination flow rate before urination will be gradually reduced until it is closed; urinating in the above manner can keep the bladder detrusor in a state of exertion at all times, and can effectively restore the detrusor function; in addition, urinating in the above manner can avoid secondary injury to the wound caused by rapid decompression inside the bladder after surgery, thereby improving the rationality of urination.
