Description

Auxiliary device for flushing double-cavity ureteral bladder and using method thereof

Technical Field

The invention relates to the technical field of medical instruments, in particular to an auxiliary device for flushing a double-cavity urinary catheter bladder and a using method thereof.

Background

In urinary surgery, some diseases of the urogenital system, patients after transurethral prostate plasmacytomy, transurethral bladder tumor electrostomy and patients with severe hematuria caused by various reasons need to keep a three-cavity urinary catheter for pressurizing and continuously flushing the bladder. The most common complications are blockage of a ureter caused by filling of a bladder blood clot, unsmooth flushing and drainage, abdominal pain caused by spasm of the bladder due to stimulation of the blood clot to shrink, and severe anxiety and pain of a patient, which seriously affect the recovery of the disease of the patient. Currently, the most clinical practice is to adopt open pulse type bladder irrigation as the first choice of bedside treatment.

In clinical practice, general anesthesia patients generally need to keep a urinary catheter, and patients in interventional therapy need to be given anticoagulant drugs in the operation, which may cause the patients to easily suffer from hematuria after the operation. For the patients, the doctor regularly washes the bladder, inserts the head of the catheter into the bladder of the patient during catheterization, and joints the tail of the catheter with the drainage part, so that the urine of the patient can flow into the drainage bag, and the urine of the patient can be led out. When the bladder of a patient needs to be flushed, the puncture needle at the tail part of the liquid medicine input tube is usually inserted into the side surface of the tail part of the catheter, flushing liquid medicine is injected into the bladder of the patient along the inner cavity of the catheter, and flushing liquid after the bladder is flushed can flow into the drainage bag, so that the bladder flushing operation is completed. Although the bladder irrigator is simple to operate, the tightness of the catheter is greatly reduced due to the puncture hole after the puncture needle penetrates the catheter for multiple times, so that the bladder irrigator cannot meet the requirement of sterility, infection is easily caused, and extra pain is brought to patients. The traditional drainage bag does not have a bladder washing interface, is used for directly pricking a catheter with a needle of an infusion apparatus for washing, and easily causes the puncture of the catheter if the operation is improper or causes the bad phenomenon that medical staff are injured by a needle. In addition, the catheter is not provided with a related fixing structure, so that the catheter cannot be fixed at a specified position, and urethral injury or ureter detachment is caused when a patient drags in the activity process.

In addition, open pulse bladder irrigation refers to irrigation through the original urinary catheter, which requires separation of the urinary catheter from the drainage end, and pulse suction with a syringe using physiological saline. This mode is relatively limited and has certain defect, because there is the syringe nipple and the ureter pipe diameter difference and leads to the mouth of pipe to connect inseparably, needs the manual fixed connection position of operator during the suction. In the operation process, urine leakage and even splashing occur at the connecting position due to improper operation methods or unstable fixation, so that the exposure rate of an operator is increased remarkably, and time and labor are wasted. In addition, repeated suction operation requires repeated separation of the three-cavity urinary catheter from the drainage part, the dredging component and the like, so that retrograde urinary infection of a patient is often caused. In order to solve the problems, the multifunctional bladder irrigation drainage pipeline is combined with clinical practice, the pipeline is not affected to be flushed when being unobstructed, the catheter can be dredged when being blocked by blood clots, the aseptic principle is followed, and the airtight flushing environment can be kept.

This prevent urine bag against current suitable for two-chamber and three-chamber ureter bladder washes, through setting up three chamber ureters, transfusion system connector and side tube mouth, urine bag connects and catheterization mouth sealing connection, transfusion system connector and the complete sealing connection of transfusion system bobbin, the transfusion system bobbin gets rid of the scalp acupuncture and twists on the transfusion system connector, can guarantee complete inclosed bladder promptly and wash or go up the medicine, reduce the risk of infecting, can effectively avoid infecting, effectively prevent that the patient from being wounded by the acupuncture, stopped the potential safety hazard. However, the patent cannot effectively dredge the blocked catheter, and the blocked catheter can be connected with an injector through a three-cavity catheter to conduct pulse type suction dredging. However, there may still be a difference in the diameter between the injector nipple and the ureter, which may cause the nozzle to be not tightly connected, and the operator is required to manually fix the connection position during suction. Often can lead to the hookup location to take place urine and reveal or splash because the improper of operation method or fix insecure in operation process to can show the exposure rate that increases the operator, waste time and energy in addition, in addition because repeated suction operation need with three chamber ureters and drainage portion, dredge repeated separation such as subassembly, often also lead to the patient to take place retrograde urinary system and infect.

According to the measured value of the hydraulic pressure in the catheter 1 by the second pressure sensor 722, the judgment of the pressure in the bladder and the filling amount of the flushing fluid of the patient by medical staff can be facilitated, and in the flushing process, when the pressure value of the second pressure sensor 722 exceeds the preset critical pressure value, the control unit 727 can make an early warning and close the electromagnetic valve switches corresponding to the first electromagnet and the second electromagnet. When the drainage operation is carried out, the catheter 1 is communicated with the pipeline of the drainage part 3. And the electromagnetic valve switch corresponding to the first electromagnet is closed, and the electromagnetic valve switches corresponding to the second electromagnet and the third electromagnet are opened. The flushing fluid or urine in the bladder flows out of the human body, flows through the catheter 1 and then flows into the drainage bottle of the drainage part 3. If the pipeline is blocked in the drainage process, the control unit 727 can judge whether the blocked pipeline is the catheter 1 or the drainage part 3 according to the difference of the pressure values collected by the second pressure sensor 722 and the third pressure sensor 723. When the catheter 1 is blocked, the section of the tube provided with the sensor is closed on one side and naturally runs through on the other side. According to the pipeline hydraulic theory, the liquid environments of the second pressure sensor 722 and the third pressure sensor 723 are in a stable state, and no pressure change exists. When there is an occlusion in the conduit of the drainage part 3, the bladder will expand and contract, providing a certain drive to the interior of the conduit of the catheter 1, wherein the pressure value measured by the second pressure sensor 722 will fluctuate and the measurement value of the second pressure sensor 722 will be higher than the measurement value of the third pressure sensor 723. The control unit 727 changes the opening and closing of the solenoid valve switch according to the determination result of the clogged pipe line obtained by the analysis processing. For example, when the catheter 1 is blocked, the electromagnetic valve switch corresponding to the third electromagnet is closed, the electromagnetic valve switches corresponding to the first electromagnet and the second electromagnet are opened at the same time, and the pulse-type liquid flow is filled into the pipeline of the catheter by using the dredging component 4 communicated with the pipeline of the washing part 2, so that the blocked part of the pipeline is dredged. When the pipeline of the drainage part 3 is blocked, the electromagnetic valve switch corresponding to the second electromagnet is closed, and the electromagnetic valve switches corresponding to the first electromagnet and the third electromagnet are opened simultaneously, so that pulse liquid flow is filled into the pipeline of the drainage part 3, and the blocked part of the pipeline is dredged.

Preferably, the dredging component 4 can charge dredging liquid flow with different pulse equivalent into the pipeline according to the actual monitored blockage condition. The shell 71 of the three-way regulating part 7 is provided with a prompting unit, and the control unit 727 judges the position of a blocked pipeline according to the collected pressure data collected by the pressure sensor and judges the blocking condition according to the pressure value when the pipeline is blocked. The processing module in the control unit can divide the jam condition into flocculent precipitate jam and blood clot jam according to the pressure data of collecting to make the early warning through the suggestion unit, and provide the jam degree reference. For example, a mild occlusion is a yellow light and a severe occlusion is a red light. When the blocked pipeline is slightly blocked due to the blockage of flocculent precipitates, medical personnel can dredge the pipeline by dredging liquid flow with smaller pulse equivalent; when the blocked pipeline is severely blocked due to the blockage of blood clots, medical personnel can dredge the pipeline by dredging liquid flow with larger pulse equivalent.

The port on the housing 71 is provided with an outer sleeve 711 capable of wrapping around the catheter and an inner embedded tube 712 inserted into the catheter. The inner tube 712 is disposed inside the outer tube 711 coaxially with the outer tube 711, and the tube body of the outer tube 711 extends outside the housing 71 so that the port of the outer tube 711 can be fitted with the closing plug 713 provided to be capable of closing the port. Preferably, the housing 71 of the three-way regulating part 7 is provided with a positioning adhesive tape 73. The positioning adhesive tape 73 can position and adhere the urinary catheter 1 on the surface of the human body.

Example 3

A method of using a dual lumen urinary catheter bladder irrigation aid comprising the steps of:

the catheter 1, the irrigation part 2 and the drainage part 3 are connected with each other by a three-way regulation part 7. The three-way regulating part 7 can selectively communicate two pipelines in the catheter 1, the flushing liquid input pipe 21 of the flushing part 2 and the drainage output pipe 31 of the drainage part 3 according to different functional requirements of flushing, drainage or blockage dredging and the like. The connection port of the three-way regulation portion 7 is provided with an outer tube 711 and an inner tube 712 capable of limiting the connected catheter port.

The irrigation part 2 is provided with a dredging assembly 4 capable of delivering a pulsed liquid flow to the blocked catheter 1 and/or drainage part 3.

The dredging component 4 at least comprises a driving part 5 which can drive the pulse liquid flow to enter the catheter 1 and/or the drainage part 3, and the driving part 5 has the functions of adjusting the flow velocity of the liquid flow to form the pulse liquid flow and controlling the pulse liquid flow to flow directionally, so that the blocked pipeline of the catheter 1 and/or the drainage part 3 in the blocked state can be dredged in a pulse mode through the pulse liquid flow in the closed channel.

In the specific dredging operation, the dredging operation is carried out,

when the pneumatic vacuum valve is used for the first time, the driving cavity bag 51 is squeezed by hands, the one-way liquid inlet assembly 61 can be automatically closed under pneumatic pressure, air in the driving cavity bag 51 is discharged through the one-way liquid outlet assembly 62 through the exhaust valve arranged on the output end 53, and then the exhaust valve is closed to enable the driving cavity bag 51 to form a vacuum state. Then the driving cavity 51 is released, the negative pressure generated in the driving cavity 51 opens the one-way liquid inlet assembly 61, and the liquid is automatically sucked into the cavity of the driving cavity 51 from the liquid storage bottle through the input end 52. When the driving cavity bag 51 stored with the flushing liquid is squeezed again, the one-way liquid outlet assembly 62 can be flushed by the liquid in the driving cavity bag 51 and discharged through the output end 53, so that the blocked pipeline is flushed, and after the external force on the driving cavity bag 51 is removed, the one-way liquid inlet assembly 61 is communicated with the cavity of the driving cavity bag 51 again, so that the flushing liquid is supplemented to the cavity of the driving cavity bag. In addition, the magnitude of the pressing force applied during the pressing operation can be artificially controlled, so that the discharged flushing liquid flow can form a pulse type dredging liquid flow with variable flow speed.

It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of the present disclosure, may devise various arrangements that are within the scope of the present disclosure and that fall within the scope of the invention. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims.
