Urethral catheter with anesthesia function

Abstract

The invention provides a catheter with an anesthesia function, belongs to the technical field of medical instruments, and solves the technical problems that an existing catheter is poor in catheterization effect, painful in the disassembly and assembly process and the like. Comprising a multi-way connector, the multi-way connector is connected with three flow guide pipes, a main pipeline and a flow limiting valve, the flow limiting valve is connected with a first quick release connector through a pipeline, the first quick release connector is connected with a urine collecting bag, two flow guide pipes are connected with a flow limiting three-way valve, the flow limiting three-way valve is connected with a gas and liquid injection pump, and the other flow guide pipe is connected with an anesthetic liquid injector. The main pipeline is sequentially provided with a catheter, a first air bag tube, an anesthetic liquid tube and a second air bag tube from inside to outside, and the end parts of the catheter, the first air bag tube, the anesthetic liquid tube and the second air bag tube are respectively provided with a catheterization hole, an excretion air bag, a plurality of rows of anesthetic holes and anesthetic air bags, urine catheterization and urine collection are convenient, the urine collection bag is easy to replace, anesthesia can be rapidly carried out on the urethra, and the insertion pain of the catheter is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and relates to a urinary catheter, in particular to a urinary catheter with anesthesia function. Background technique [0002] For patients with bladder inability to urinate or difficulty urinating, a catheter is needed to assist urination. After a period of catheterization, it can help the bladder return to normal function (normal urination), and now the catheter is used to pass the tube through the urethra. Inserted into the bladder, during use, the urethra will cause pain due to contact with the tube, so now the catheter needs to be improved. The tube is located in the urethra to discharge anesthetic fluid, and the urethra is anesthetized through the anesthetic fluid to relieve pain. [0003] After searching, for example, Chinese patent documents disclose a urinary catheter with an inflatable valve [application number: CN202023138916.3; publication number: CN214860428U]. This cathe...

AI Technical Summary

Problems solved by technology

This urinary catheter with an inflatable valve includes a catheter body, the catheter body includes an external inflation tube and an internal catheter, the exterior of the catheter body is provided with an external inflation tube, and the external inflation tube The inside of the tube is equipped with an internal catheter, and the right end of the catheter body is equipped with a drainage joint. Both sides of the outer wall of the catheter body and the left side of the drainage joint are symmetrically provided with small drainage holes. The outer wall of the catheter body and the left side of the small drainage hole are equipped with a catheter balloon, the left side of the catheter balloon is equipped with an inflatable valve, and the left end of the catheter body is installed with a Catheter connector, the upper side of the catheter body and the right side of the catheter connector is equipped with an air bag inflation tube, although the overall equipment structure is simple, easy to use, not easy to fall off during use, and stable and practical Higher, however, does not have anesthesia function and cannot relieve the patient's pain when inserting a urinary catheter
