Description

Self-circulation bladder irrigator

Technical Field

The invention relates to the technical field of medical instruments, in particular to a self-circulation bladder irrigator.

Background

For patients with various urinary system tumor related diseases such as bladder cancer, prostatic cancer, ureter tumor, etc., blood clots formed after the tumor is ulcerated and bleeded are difficult to be discharged out of the body when the volume is large. At present, the indwelling catheter is usually adopted for bladder irrigation clinically, the catheter is blocked often, the pain of a patient is aggravated, the bladder is excessively full due to the blockage, the intravesical hemorrhage can be further aggravated, the vicious circle is formed, and the blood clots in the bladder are difficult to be removed cleanly by a non-operative method. The method of cystoscope irrigation or surgical removal not only increases the pain and economic burden of the patient, but also causes secondary damage to the patient, has high requirements on the physique and tolerance of the patient, and also requires the patient to be moved to be in a special position, so that the mobility of the patient can be increased while the patient is moved, the bleeding volume of the urinary system is increased, and the vicious circle is formed again. For the elderly or the patients with poor constitution, only non-operative methods can be adopted, the curative effect is very little, and even the restraint is unforeseeable.

Detailed Description

The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings.

As shown in fig. 1: the utility model provides a self-loopa bladder flusher, including the flushing pipe, the flushing pipe comprises outer tube 1 and inner tube 2, link together through a plurality of cradling pieces 3 of axial evenly distributed between inner tube 2 and the outer tube 1, the lumen of inner tube 2 is flush fluid inlet channel, the annular chamber between inner tube 2 and the outer tube 1 is flush fluid drainage channel, the tail end of inner tube 2 is provided with the syringe connector, the tail end lateral wall of outer tube 1 is provided with the leakage fluid dram, flush fluid inlet channel through inner tube 2 lasts to injecting into the bladder flush fluid, the flush fluid stops the back in the bladder that rolls, can flow through the flush fluid drainage channel between inner tube 2 and the outer tube 1 and discharge, reach self-loopa effect. The inner tube 2 is internally provided with a linkage rod 4 along the axis thereof, the linkage rod 4 is supported by two bearings, the outer ring of the bearing is fixedly connected with the inner tube 2 by a support bar, the linkage rod 4 passes through the inner ring of the bearing and is fixedly connected with the inner ring, the linkage rod 4 can rotate in the inner tube 2 by the two bearings, the lower end of the linkage rod 4 is sleeved with an active twisted blade 5, the upper end of the linkage rod 4 extends out of the inner tube 2 and is sleeved with a silt scattering twisted blade 6, the twisting directions of the active twisted blade 5 and the silt scattering twisted blade 6 are opposite, the purpose of the arrangement is to ensure that the backflow flushing fluid generates rotary thrust on the silt scattering twisted blade 6 when flowing through the silt scattering twisted blade 6, so that the silt scattering twisted blade 6 has stronger rotary effect, and the active twisted blade 5 is used for driving the linkage rod 4 to rotate, when the flush fluid flows in the lumen of inner tube 2, can drive initiative distortion blade 5 and rotate, and then drive gangbar 4 and rotate, the effect that the distortion blade 6 was broken up to the extravasated blood is broken up the blood clot smugglutinated in with the flush fluid, the blood clot of being convenient for discharges from flush fluid drainage channel, can drive the extravasated blood when gangbar 4 rotates and break up distortion blade 6 and rotate, make the blood clot broken up when the flush fluid drainage channel mouth of flowing through, get into flush fluid drainage channel smoothly, the bladder of finally discharging.

As shown in fig. 2: in order to prevent the head end of the flushing pipe from damaging the inner wall of the urethra in the advancing process of the urethra, the head end of the outer pipe 1 is provided with a curled edge 7 which extends inwards, the curled edge 7 not only can avoid the loss of the urethra, but also can partially hide the twisted blades 6 which are scattered by extravasated blood.

As shown in fig. 3: in order to enable the active twisted blades 5 to generate a larger rotating force, 5 active twisted blades 5 are sleeved at the lower end of the linkage rod 4, the active twisted blades 5 are broad palm twisted blades with a larger area, the broad palm twisted blades mean that the shape of the blades is close to a circle or an ellipse, and the blades with the shape are beneficial to generating stronger rotation.

As shown in fig. 4: in order to enable the extravasated blood scattering twisted blades 6 to have a good breaking effect, the upper end of the linkage rod 4 is sleeved with 7 extravasated blood scattering twisted blades 6, each extravasated blood scattering twisted blade 6 is a slender willow leaf twisted blade, the outer edge of each extravasated blood scattering twisted blade 6 is provided with a cutting edge for cutting blood clots, and the slender willow leaf twisted blades 6 help to provide cutting frequency and can fully break the blood clots in the bladder.

The use method of the self-circulation bladder irrigator comprises the following steps:

before use, the bladder flusher is disinfected, then the end of the flushing pipe is inserted into the urethra from the urethral orifice of a patient and advances along the urethra, the end of the flushing pipe is judged to stop advancing when entering the bladder according to the length of the inserted flushing pipe, a syringe with flushing liquid is connected to the tail end of the inner pipe, a liquid discharge pipe is connected to a liquid discharge port of the outer pipe, a push rod of a piston rod is pushed forcibly, the flushing liquid in the syringe is injected into the inner pipe and flows into the bladder through the inner pipe, the flushing liquid drives the active twisted blades to rotate in the flowing process of the inner pipe and further drives the linkage rod to rotate, finally the extravasated blood is driven to be scattered and twisted blades to rotate, as the inner pipe continuously injects the flushing liquid into the bladder, the flushing liquid can flow out along the annular cavity between the inner pipe and the outer pipe after staying in the bladder (as shown in figure 5), and can be scattered and twisted blades to be broken by the rotating extravasated blood when, so as to smoothly discharge the liquid, when the liquid discharged from the liquid discharge pipe does not carry blood clots, the flushing work of the bladder is completed, and the flushing pipe is pulled out from the urethra.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
