Catheter with medicine device

Abstract

The invention discloses a catheter with a medicine device. The catheter comprises a catheter body and the medicine device, an arc insertion part is arranged at one end of the catheter, and a hose is inserted in the other end of the catheter body; a first through hole communicated with the interior of the catheter body is formed in the arc insertion part, a closed spherical airbag sleeves the portion, close to the arc insertion part, of the exterior of the catheter body, and a first channel communicated with the spherical airbag is formed in the catheter wall of the catheter body. The catheterhas a good fixing effect, the bladder part of a patient can also be cooled, and the scorching discomfort of the patient is eliminated; meanwhile, medicine liquid containing anesthetic medicine and anti-inflammation and anti-immunoreaction medicine is slowly conveyed to the bladder part and urethra part of the patient for a long time, the catheter helps the patient to relieve the pain feeling of the bladder part and urethra part, the medicine device can be conveniently disassembled and can be recycled, the treatment cost is effectively lowered, and the catheter is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a urinary catheter with a drug device. Background technique [0002] Catheterization, in medicine, is the insertion of a catheter through the urethra into the bladder to drain urine. Catheterization is divided into two types: indwelling catheterization and intermittent catheterization. The former urinary catheter remains in the patient's body all the time, and it is pulled out or replaced with a new tube regularly when the condition permits. The latter catheterizes every 4-6 hours, and the catheter is pulled out after the bladder is emptied. [0003] When medical personnel do catheterization for patients, because most patients will have weak inflammation in the bladder when using the catheter, in the case of inflammation, the bladder will heat up and cause the patient to feel burning discomfort. At the same time, the patient There will be pain in th...

Problems solved by technology

[0003] When medical personnel do catheterization for patients, because most patients will have weak inflammation in the bladder when using the catheter, in the case of inflammation, the bladder will heat up and cause the patient to feel burning discomfort. At the same time, the patient There will be pain in the bladder and urethra of the patient. Some patients are more sensitive to pain, which makes some patients unbearable. Medical staff generally use a local anesthetic to anesthetize the patient's bladder and urethra. The action time of anesthetic drugs is very short and cannot persist for a long time. Therefore, a urinary catheter with a drug device is proposed
