Problems solved by technology

Generally, after the drug is infused into the bladder through the catheter, due to gravity or the liquid outflow of the drug, on the one hand, the contact area between the drug and the bladder wall is limited, and the patient needs to change the body position so that the drug can contact the bladder mucosa more to achieve the therapeutic effect; on the other hand, The drug liquid cannot adhere to the bladder wall well and uniformly for a long time. With the continuous bladder activity and urination cycle, the drug is almost lost. It needs long-term repeated infusion for a certain period of time, which is time-consuming and laborious, and greatly increases the drug expenditure and the patient's burden.

Abstract

An auxiliary bladder perfusion device comprises a slender catheter body made of soft and elastic materials; one end of the catheter body can be placed into the bladder, the other end of the catheter body can be used for injecting liquid or gas, and the catheter body comprises a water injection cavity, an air inflation cavity and a medicine injection pipe; and the water injection cavity and the air inflation cavity can be placed into the bladder along with the catheter body, a water injection opening and an air inflation opening are formed in the outer portion of the catheter body and can inject water into the water injection cavity and inflate the air inflation cavity, and the medicine injection pipe can inject in-vitro liquid medicine into the bladder.

Description

technical field [0001] The invention relates to a device for assisting bladder perfusion. Background technique [0002] Bladder infusion is a common treatment operation in urology, mainly used in bladder diseases, such as bladder infusion of chemotherapy drugs after bladder cancer surgery, drug infusion therapy of interstitial cystitis, etc. Generally, after the drug is infused into the bladder through the catheter, due to gravity or the liquid outflow of the drug, on the one hand, the contact area between the drug and the bladder wall is limited, and the patient needs to change the body position so that the drug can contact the bladder mucosa more to achieve the therapeutic effect; on the other hand, The drug liquid cannot adhere to the bladder wall well and uniformly for a long time. With the continuous bladder activity and urination cycle, the drug is almost lost. It needs long-term repeated infusion for a certain period of time, which is time-consuming and laborious, and...
