Description

Auxiliary bladder perfusion device

Technical Field

The invention relates to a device for assisting bladder perfusion.

Background

Bladder perfusion is a common treatment operation in urology surgery and is mainly applied to bladder diseases, such as bladder perfusion of chemotherapy drugs after bladder cancer surgery, drug perfusion treatment of interstitial cystitis and the like. Generally, after the medicine is infused into the bladder through a catheter, due to the gravity or the liquid outflow effect of the medicine, on one hand, the contact area of the medicine and the bladder wall is limited, and the patient needs to change the body position to enable the medicine to contact more bladder mucosa, so that the treatment effect is achieved; on the other hand, the liquid medicine can not be well adhered to the bladder wall in a uniform way for a long time, the medicine is almost lost along with continuous bladder activity and urination period, the medicine needs to be repeatedly infused for a long time in a certain time, time and labor are wasted, and the medicine expenditure and the burden of a patient are greatly increased.

Aiming at the defects, how to realize uniform bladder wall inner covering and long-term adhesion on the bladder mucosa during perfusion does not need to repeatedly change the body position of a patient after perfusion, and the medicine can uniformly reach and be kept at each corner in the bladder wall as soon as possible, so that the medicine is fully and efficiently utilized, the medicine waste is reduced, the pain of the patient in repeated perfusion and the unnecessary course of treatment and treatment cost are reduced, and the burden of medical workers and the exposure, contact and inhalation risks of the medicine are also reduced.

Disclosure of Invention

In view of the above prior art, it is an object of the present invention to provide a device for assisting the perfusion of the bladder.

The technical scheme of the invention is realized as follows: the utility model provides a supplementary device that bladder was perfused, includes that the soft elastic material that is rich in makes long and thin pipe body, and the injectable liquid of other end or gas in the bladder can be put into to pipe body one end, and the pipe body includes water injection chamber, aerifys chamber and injection pipe, and water injection chamber and aerify chamber can follow the pipe body and put into the bladder and the pipe body outside is equipped with water filling port and inflation port and can be respectively toward water injection chamber water injection to aerify the chamber, and the injection pipe can be with external liquid medicine injection bladder in.

The beneficial effect of design like this is: the device and the treatment method are rapid, simple, convenient, safe and minimally invasive, and can be used for outpatient treatment. Under the operation of medical workers, the perfusion medicine can be fully contacted with the bladder wall under the guidance of B ultrasonic, thereby improving the perfusion treatment effect, reducing the medicine waste, lightening the medicine charge burden of patients, reducing the medicine exposure of the medical workers and the like. The medicine filled in the bladder can be conveniently and quickly adhered to the bladder wall by inflating, so that the effect of filling treatment is effectively enhanced and the time of medicine treatment is prolonged.

Furthermore, the water injection cavity is positioned in the inflatable cavity, so that the water injection cavity can inject water to expand the inflatable cavity, the fixation is convenient, and the position of the inflatable cavity in the bladder can be controlled by adjusting the volume of air and water, so that the liquid medicine in the bladder can fully flow and uniformly contact with the bladder.

Meanwhile, the hydrogel mixed with the hydrogel medicine can be effectively and uniformly adhered to the mucous membrane of the urinary bladder for a long time, and the medicine hydrogel in each grid has certain flexibility and can effectively resist the medicine desquamation caused by the change of the filling and contraction of the urinary bladder.

Further, be equipped with four water injection chambeies and four gas filling chamber and water injection chamber interval arrangement at least, water injection chamber and gas filling chamber all are equipped with independent water filling port or inflation inlet, and the rotation that can control how much the realization water injection chamber of water yield like this stirs the mixture and makes the medicine more even to the medicine.

Furthermore, the water injection port is provided with a water pump, and the inflation port is provided with an inflation pump, so that automatic control can be realized.

Furthermore, the water injection pump and the inflator pump are controlled by a circuit board to realize full automation of water injection, water pumping, air inflation and air suction, a start button, a pause button and a stop button are arranged on the circuit board, overflow valves are connected outside the water injection pump and the inflator pump to enable water injection pressure and air inflation pressure to be stabilized in a safe range, the start button can be used for simultaneously injecting water and inflating after being pressed down, the circuit board stops working after reaching certain pressure, the circuit board enters a rolling mode after certain time, water injection is started in a left lower water injection cavity and a left upper water injection cavity, water pumping is started in a right lower water injection cavity and a right upper water injection cavity, air exhaust is started in the left lower air injection cavity and the left upper air injection cavity, air inflation is started in the right lower air injection cavity and the right upper air injection cavity, the left gravity is larger than that of a right catheter body to start anticlockwise rotation, water pumping is started in the left lower water injection cavity and the left upper water injection cavity after rotating, aerify the chamber and the upper right in the right and aerify the chamber and begin to exhaust for the gravity on the left side is less than and begins clockwise rotation in the pipe body on the right, rotates half a circle back and rotates anticlockwise again, stop work again so circulation certain time, the water injection chamber with aerify the chamber and begin to exhaust or draw water and take out water to the greatest extent and take out futilely and stop the action again, design like this can be realized by the circuit that full automatic control has improved the convenience greatly and has better drug therapy effect, it is very practical to old person and the crowd of weak many diseases.

Furthermore, the water injection cavity and the air inflation cavity are independently manufactured and can be placed into the bladder together with the catheter body, but can be taken out one by one, and the air exhaust and the water pumping can have residues, so that the synchronous taking out is difficult, but the single taking out is easy.

Furthermore, the water injection cavity and the inflation cavity are provided with electromagnetic switching valves so that any water injection cavity and any inflation cavity can be switched between inflation and water injection modes, the rolling speed can be greatly increased and the number of the inflation pumps and the water injection pumps can be reduced by the design, namely, all the water injection cavities and the inflation cavities use the same inflation pump and the water injection pump and only need to use the valves for switching.

A medicine for assisting bladder perfusion is prepared by adding hydrogel material into perfused medicine, and mixing. The injected medicine is uniformly mixed with hydrogel substances, so that the medicine can be effectively and uniformly adhered to the mucous membrane of the urinary bladder for a long time, and the medicine hydrogel in each area has certain flexibility and can effectively resist the falling of the medicine caused by the change of the filling and contraction of the urinary bladder.
