Description

An openable and closable bladder treatment lavage device

technical field

The utility model relates to the technical field of medical devices, in particular to an openable and closable bladder treatment lavage device.

Background technique

As we all know, urinary system diseases, such as urinary calculi, bladder, urethral injury, renal pelvis and ureter obstruction, prostatic hyperplasia, renal abscess, acute and chronic cystitis and hydronephrosis, often require bladder lavage, catheter lavage therapy is One of the common treatments for bladder disease, by unclogging the catheter, removes accumulated secretions and the chemicals they produce, thereby eliminating lumps and pains and preventing them from becoming cancerous.

Clinically, many patients need bladder lavage liquid treatment, such as bladder lavage and chemotherapy after bladder cancer patients, but there is no unified and applicable lavage catheter. Many clinicians use urinary catheters for bladder lavage. , in the existing bladder lavage device, the latex head cannot directly flush the medicine, and it needs to be connected with a joint and a needle. During the process of filling the medicine, the nurse is prone to leakage of chemotherapy drugs due to the poor connection, causing personal injury to the nurse. After washing, only the catheter that can be used for more than 1 month can only be discarded as a disposable material, which not only costs a lot and is prone to waste of medical resources, but also is prone to reflux and spillage of the medicinal solution during the perfusion process. It will increase the difficulty of operation, loss of medicinal solution, and even affect the effect of bladder lavage due to the reduction of the dose and concentration of medicinal solution in the bladder. In addition, after the drug solution is infused, the catheter needs to be pulled out, and the drug solution needs to stay in the bladder for as long as possible. Patients often experience frequent urination, urgency, and early urination, which affects the efficacy of the drug solution. Because chemotherapy drugs are expensive, Premature urination is a loss to the patient, so an openable and closable bladder therapy irrigation device needs to be designed to solve the above problem.

Chinese patent application: CN201220032131.4, discloses a disposable single-lumen bladder lavage catheter, the front end of the catheter is a pointed blind end, the front end of the catheter has a side hole, the end of the catheter is enlarged into a cylindrical shape, and a one-way valve is filled, The center of the one-way valve is provided with a needle-like small hole, and the one-way valve is surrounded by a valve sleeve. The catheter is not only low in cost, but also easy to use. The injected liquid will not overflow and reflux, which greatly reduces the difficulty of bladder lavage operation and can ensure that all the required liquid is injected into the bladder to the greatest extent. Sterilization treatment meets the requirements of aseptic operation of bladder lavage, and is more suitable for elderly male patients who have difficulty urinating and who are difficult to place ordinary double-lumen urinary catheters. However, there is no disclosure about a lavage device that can avoid the extravasation of the medicinal solution, keep the medicinal solution in the bladder for a long time, and can extract the medicinal solution when urination is required, and then refill it after urination.

To sum up, there is an urgent need for a lavage device that can avoid the extravasation of the medicinal solution, keep the medicinal solution in the bladder for a long time, and can extract the medicinal solution when urinating and refill it after urination. Not reported.
