Description

Technical Field

[0001] The present invention relates to the technical field of urological surgical instruments, and particularly to a drug circulation flushing device for hollow cavity organs of the urinary system after surgery. Background Art

[0002] In urological surgeries, surgeries on hollow cavity organs account for a quite large proportion. After surgeries for diseases such as bladder stones, bladder tumors, and benign prostatic hyperplasia, in order to avoid blood clot blockage caused by postoperative bleeding, continuous flushing of the hollow cavity organs for 24 hours is required. Currently, the principle of the mainstream flushing device is generally: introducing saline into the hollow cavity for flushing through an infusion tube, and then leading it out of the body through a drainage tube, and the waste liquid can be filtered and disposed of.

[0003] For example, the Chinese patent with the publication number "CN203943949U" discloses "a circulating flushing device for hollow cavity organs of the urinary system after surgery", the main structure of which includes a base and a bladder fistula. There is an intermediate partition on the base. A liquid storage tank is provided at the bottom of the intermediate partition and above the base. The intermediate partition divides the liquid storage tank into two parts, a waste liquid storage cavity and a purified liquid storage cavity. The inlet and outlet of the filtering device are respectively communicated with the waste liquid storage cavity and the purified liquid storage cavity. A transparent glass cavity sphere is provided at the top of the intermediate partition. An outlet is provided on the transparent glass cavity sphere. A stainless steel pipe, a metal bellows, and a support pipe communicated with the bladder fistula tube are sequentially arranged at the outlet. This circulating flushing device for hollow cavity organs of the urinary system after surgery filters the flowing liquid through the provided filtering device, and then realizes the circulating flow of the liquid through a booster pump. However, a general filtering device needs to clean the internal filter screen regularly, and during operation, due to the gradual increase of debris, its filtering effect will seriously decline.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 and Figure 2 , a drug circulation irrigation device for postoperative hollow cavity organs of the urinary system, including a support base that plays a supporting role and a driving motor installed in the motor fixing housing. Start the driving motor and control the rotation direction of the rotor, so that the rotor drives the screw to rotate in a fixed direction, causing the medium around the screw to flow towards the open end of the horizontal filtering chamber.

[0022] In order to achieve the driving function of the liquid and the separation effect of impurities, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, a separate filtering mechanism needs to be set up. Inside it, there is a horizontal separation cylinder that is fixedly installed in the support base and has a hollow interior, a screw installed inside the horizontal separation cylinder that can cause the surrounding medium to move to one side when rotating, filtering holes provided at the bottom of the horizontal separation cylinder that can filter solids and liquids, a moving limit disk installed at the end of the horizontal separation cylinder for discharging solid waste, and a spiral spring installed at one end of the moving limit disk that provides an elastic damping effect when the moving limit disk moves under the action of the waste. First, connect the medium input channel to the liquid discharge port of the bladder fistula tube, and then connect the pipeline connection channel to the liquid inlet of the bladder fistula tube. When the flowing medium passes through the filtering holes, solid debris will flow towards the moving limit disk, and the filtered liquid will be discharged outward through the filtering holes, causing the solid debris to accumulate. When the pressure between the accumulated solid substances is greater than the elastic strength of the spiral spring, the moving limit disk will move away from the fixed limit disk structure, and the accumulated solid waste will be exposed. The staff can apply a downward pressing force to the solid waste, causing the solid waste to fall off. Under the elastic action of the spiral spring, the moving limit disk can be reset in a timely manner, thus realizing the driving function for the liquid and the separation effect for the impurities.

[0023] For the specific structure of the said separate filtering mechanism, please refer to Figure 3 and Figure 4, including a horizontal separation cylinder fixedly installed in a support base and a movable limit disk. The interior of the horizontal separation cylinder is provided with a horizontal filter cavity with one end open. The horizontal separation cylinder is provided with a fixed limit disk structure integrally formed with it around the open end of the horizontal filter cavity. One end of the horizontal separation cylinder is provided with a mounting plate structure integrally formed with it. The mounting plate structure is fixedly connected to the end of the motor fixed housing. The interior of the mounting plate structure is provided with a shaft body mounting hole communicating with the external space and the horizontal filter cavity. The horizontal separation cylinder is provided with a medium input channel integrally formed with it and communicating with the side of the medium reserve cavity on the outer circumferential surface near the shaft body mounting hole. The horizontal separation cylinder is provided with filter holes communicating with the side of the horizontal filter cavity and the external space and used for the filtering effect on the outer circumferential surface in the middle area of the horizontal filter cavity. A horizontal rotating shaft is installed in the shaft body mounting hole of the horizontal separation cylinder through a bearing. One end of the horizontal rotating shaft in the external space is provided with a rotor fixing groove. The rotor end of the driving motor is fixedly installed inside the rotor fixing groove. A rotatable screw is placed inside the horizontal filter cavity. One end of the screw is provided with a shaft body fixing groove for fixedly installing the end shaft body of the horizontal rotating shaft. Three annularly arrayed first rod holes are provided in the plate body of the movable limit disk. Three horizontal limit rods passing through the first rod holes are fixedly installed at the end of the fixed limit disk structure. A limit plate structure is fixedly installed at the end of each horizontal limit rod. A compression spring is placed on the rod body of each horizontal limit rod. One end of the compression spring is fixedly installed at the end of the limit plate structure, and the other end is fixedly installed at the end of the movable limit disk.

[0024] In order to further adsorb and separate tiny impurities in the liquid, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , an activated carbon adsorption mechanism needs to be set up. Inside it, there is an annular fixed housing fixedly installed around the horizontal separation cylinder and capable of draining the liquid from the direction of the filter holes, a middle liquid flow housing fixedly installed below the annular fixed housing and with activated carbon particles placed inside, and a pipe docking channel fixedly installed at the bottom of the middle liquid flow housing and capable of discharging the purified liquid. Open each middle liquid flow housing, lay activated carbon particles on the upper surface of each filter plate, and then assemble the whole middle liquid flow housing. When the preliminarily filtered liquid enters the inside of the middle liquid flow housing, the tiny impurities and odors in the flowing liquid will be adsorbed by the activated carbon, thereby further adsorbing and separating the tiny impurities in the liquid.

[0025] Regarding the specific structure of the activated carbon adsorption mechanism, please refer to Figure 5 and Figure 6, including an annular fixed outer shell sleeved around the periphery of the horizontal separation cylinder. An annular liquid flow chamber communicating with filter holes is arranged inside the annular fixed outer shell. A sealing ring capable of preventing liquid leakage is fixed at the installation area of the annular fixed outer shell and the horizontal separation cylinder. A top liquid flow channel with an internal structure communicating with the annular liquid flow chamber is arranged in the bottom area of the annular fixed outer shell. A middle liquid flow outer shell with a hollow internal structure is fixedly installed at the bottom of the top liquid flow channel. A filter plate is fixedly installed in the middle area of the middle liquid flow outer shell. A bottom liquid discharge channel is fixedly installed at the bottom end of the filter plate at the bottom layer. A pipe docking channel with an integral structure is arranged at the bottom end of the bottom liquid discharge channel.

[0026] During use, first, dock the medium input channel with the liquid discharge port of the vesicostomy tube, then dock the pipe docking channel with the liquid inlet of the vesicostomy tube, start the drive motor, and control the rotation direction of the rotor, so that the rotor drives the screw to rotate directionally, making the medium around the screw flow towards the open end of the horizontal filtration chamber. When the flowing medium passes through the filter holes, solid debris will flow towards the movable limit disc, and the filtered liquid will be discharged out through the filter holes, thus causing the solid debris to accumulate. When the pressure between the accumulated solid substances is greater than the elastic strength of the spiral spring, the movable limit disc will move away from the fixed limit disc structure, and the accumulated solid waste will be exposed. The staff can apply a downward pressing force to the solid waste, so that the solid waste falls off, and the movable limit disc can be reset in time under the elastic action of the spiral spring, thus realizing the driving function of the liquid and the separation effect of impurities. When the preliminarily filtered liquid enters the middle liquid flow outer shell, the tiny impurities and peculiar smell in the flowing liquid will be adsorbed by the activated carbon, further adsorbing and separating the tiny debris in the liquid.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
