Description
Technical Field
The utility model relates to the field of medical equipment, in particular to a catheter connector and a urination device.
Background
At present, a large number of patients with urination disorders exist in China, such as trauma paraplegic patients, and a large number of paraplegic and hemiplegic patients caused by cerebrovascular and spinal vascular diseases. And a patient with dysuria will suffer 100% impairment of renal function if the intravesical pressure during the storage and micturition periods continues to exceed safe bladder pressure values, and this continues for more than one year. For example, after a spinal cord trauma period, if urinary tract monitoring, such as stress and infection, is neglected, the main cause of death in patients with spinal cord injury is renal failure uremia; conversely, if attention is paid to monitoring and processing of the urinary tract system, the occurrence of serious complications of the urinary system can be greatly reduced by controlling urine with low pressure and preventing and treating infection.
For patients with urination disorder, low-pressure control of urine, namely low-pressure urine storage and low-pressure urine discharge, is required, so that structural and functional changes (such as bladder contracture, formation of a trabecular diverticulum of a bladder, kinked and twisted ureter, hydronephrosis and the like) of the whole urinary tract system can be prevented or delayed, and the renal function is protected.
A variety of urination devices are currently used for the above patients.
At present, a common urination device can adopt an indwelling urethral catheter which mainly comprises a urethral catheter inserted into the urethra and a urine bag connected with the lower end of the urethral catheter. The urinary catheter with the structure can continuously guide out urine in the bladder, and side effects such as bladder contracture and the like can occur if the urinary catheter is used for a long time; in addition, the urine bag of the catheter can store urine for too long time, and is easy to generate bacterium breeding to cause retrograde infection.
To avoid urinary tract infections, the urinary catheter needs to be clamped closed, but it is difficult for both patients and medical staff to decide when to open the urinary catheter every day. The current common method is to open the urinary catheter at regular time, for example, once every 4-6 hours, but the urine volume is influenced by drinking water, food water content, weather, sweat, medicines and the like, so the mechanical timed open urinary catheter lacks strict scientificity, and cannot realize low-pressure urine storage and low-pressure urine excretion.
An automatic pressure-sensitive indwelling catheterization device is disclosed in the utility model patent application No. 200520027099.0, publication No. CN 2810609Y, as shown in fig. 1 and 2.
As shown in figure 1, the lower end of a catheter 1 of the urethral catheterization device is connected with a urine bag 4, a water stop clip 3 is further installed at the lower end of the catheter, a pressure relay 8 and an electromagnetic valve 11 are additionally installed on the catheter 1, and a power supply 9 and a time relay 10 are connected to the output end of the pressure relay 8 and the control end of the electromagnetic valve 11. Thus, when the urine reaches a certain pressure, the pressure relay 8 acts to conduct the power supply 9, the power supply 9 supplies power to the electromagnetic valve 11 through the time relay 10, so that the electromagnetic valve 11 acts to conduct the urine; when urine is discharged, the pressure relay 8 is reset, the time relay 10 is powered off after delaying for a period of time, the electromagnetic valve 11 is reset, and the catheter 1 is closed.
Therefore, the urinary catheter is additionally provided with the electromagnetic valve 11, so that the catheterization can be started when the urine reaches a certain pressure, the low-pressure urine storage and the low-pressure urine excretion are ensured to a certain extent, the function of the kidney is protected, and the infection is reduced. However, the urinary catheterization apparatus having the above-described structure has disadvantages in that:
the pressure relay 8 is a pressure switch, whether the bladder pressure reaches a preset value is detected by adopting the pressure relay 8, and the measurement precision is low, the accuracy is inaccurate and the reliability is low; the preset value is not given, and if the preset value is unreasonably set, the function of the urinary tract system and even the function of the kidney can be influenced;
when the pressure relay 8 detects that the pressure reaches a preset value, the electromagnetic valve 11 is opened, so that under some special conditions that the bladder pressure is increased instantaneously due to instantaneous increase of the abdominal pressure, even if the bladder pressure does not reach the preset value at the moment, the electromagnetic valve 11 is opened, and the condition of opening by mistake is caused;
in addition, the opening time of the electromagnetic valve 11 is controlled by the time relay 10, but the accuracy and reliability of the time relay 10 are low, and the urination time may be shorter than the preset time, so that residual urine may be retained in the bladder, and the bladder high-pressure urine storage and urinary tract infection may be caused after long-term use, thereby affecting the functions of the bladder and even the kidney.
Therefore, the above-mentioned catheterization device has low safety in practical use, cannot ensure low-pressure urine storage and low-pressure urination if used for a long time, and can affect the functions of the bladder and even the kidney.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
Implementation mode one
The utility model provides a catheter connector, as shown in fig. 2, this catheter connector includes the first interface 206 of making the leakage pipe with ureter or bladder and being connected, the second interface 207 of being connected with the drainage tube of drainage bag and the pipeline 208 between this first interface 206 and the second interface 207, and wherein, this catheter connector still includes:
a data acquisition unit 201 for acquiring the pressure in the bladder and transmitting the pressure signal;
the central processing unit 202 is connected with the data acquisition unit 201 and is used for receiving the pressure signal transmitted by the data acquisition unit 201, judging whether the pressure is equal to or greater than a preset pressure, if so, judging whether the pressure is effective, and if so, transmitting the signal;
and an alarm unit 203 connected to the central processing unit 202 for receiving the signal transmitted by the central processing unit 202 and giving an alarm according to the signal.
Therefore, the urinary catheter joint can detect the pressure in the bladder in real time, accurately judge whether urination is needed or not and give an alarm in time, and is small in size, light in weight and convenient to use; the long-term application can greatly reduce the damage of the structure and the function of the upper urinary tract system, such as the tortuosity, the torsion, the folding, the obstruction, the expansion, the hydronephrosis and the like of the ureter, and achieve the purpose of protecting the renal function.
The automatic alarm through the alarm unit 203 can accurately and timely remind patients or medical staff to open the clamped drainage tube in time and discharge urine in the bladder, so that the pressure in the bladder is reduced, and the condition that the hydronephrosis vesicoureteral reflux is prevented by controlling urine at low pressure is achieved.
In this embodiment, the central processing unit 202 may include: a receiving unit and a processing unit (not shown); the receiving unit is used for receiving the pressure signal transmitted by the data acquisition unit 201; the processing unit is connected with the receiving unit and used for judging whether the pressure is equal to or greater than the preset pressure, if so, judging whether the pressure is effective, and if so, transmitting the signal.
In this embodiment, the preset pressure may be a bladder safe pressure, which is currently indicated by clinical urodynamic studies in the urological branch to be 40cmH 2O. If the intravesical pressure in the urine storage period of any patient with urination disorder continuously exceeds 40cmH2O, the urination period continuously exceeds 60cmH2O, and 100 percent of renal functions lasting more than one year can be damaged, for example, after a spinal cord injury patient safely passes a spinal cord trauma period, if monitoring of the urinary tract system (mainly pressure and infection) is neglected, the main death cause of the patient is renal failure uremia.
Therefore, the urination time can be accurately judged according to the safe pressure through the urine pipe joint, low-pressure urine storage and low-pressure urination are really realized, the occurrence of serious complications of the urinary system is greatly reduced, the structural and functional changes (such as bladder contracture, formation of trabecular diverticular chambers of the bladder, tortuosity and breakage of ureters, hydronephrosis and the like) of the whole urinary tract system are prevented or delayed, and the renal function is protected.
In this embodiment, the data acquisition unit 201 may employ a digital pressure sensor. For ease of use, the catheter adapter may be maintained at the pubic symphysis level during application, such that the transducer transition point is located in the conduit 208 through which the urine flows, thereby providing both ease of use and assurance that the sensed pressure is a true reflection of the pressure within the bladder. But is not limited to such. Therefore, the pressure in the bladder can be monitored in real time, the pressure signal can be converted into a data signal to be transmitted to the central processing unit 202, and the sensor has low power consumption and high measurement precision, and can reach plus or minus 1cmH2O, which is not reached by pressure relays and the like.
The central processing unit 202 may employ a low power embedded central processing unit.
The alarm unit 203 can remind the patient or the medical staff that the pressure in the bladder of the patient reaches or exceeds a safe pressure value through sound or vibration and the like, the patient needs to empty the bladder in time, and at the moment, the patient or the medical staff can open the clamped drainage tube to empty the urine in the bladder.
In the present embodiment, when the processing unit determines that the detected pressure is equal to or greater than the safe pressure value, it is further determined whether the pressure is effective, that is, whether the pressure is continuously increased in the bladder due to the bladder overfilling, which aims to avoid the occurrence of false alarm in some special cases that may cause the abdominal pressure to be increased instantaneously, such as the false increase of the bladder pressure due to posture change, external factors or other factors, even if the bladder pressure does not reach the preset pressure at this time. This is because the bladder pressure is abdominal pressure + detrusor pressure, and the factors that cause the abdominal pressure to increase in the twinkling of an eye in daily life are more, and this kind is because the increase in the twinkling of an eye of external abdominal pressure, but the increase in pressure of bladder detrusor origin causes the increase in bladder pressure should be ignored, so the utility model discloses a catheter connector can discern and ignore this kind of abdominal pressure rise in the twinkling of an eye or for a short time cause the bladder pressure to increase pseudo-image (say this kind of discernment and neglect the process and the ability of pseudo-image are delay), thereby solved the problem that exists in the relevant art.
In this embodiment, whether the pressure is effective can be determined as follows: judging whether the duration time of the pressure exceeds a first preset time, if so, judging that the pressure is effective, namely the pressure is the continuous increase of the pressure in the bladder caused by the over-filling of the bladder; if the first preset time is not exceeded, the pressure is judged to be invalid, namely the pressure is possibly a false instantaneous pressure change caused by instantaneous intermediate body position change. However, this determination is only a specific embodiment, and is not limited thereto, and other determination methods may be adopted.
