Urethral catheter with anesthesia function

Abstract

The invention discloses a catheter with an anesthesia function, and belongs to the technical field of medical instruments. The catheter with the anesthesia function comprises a containing box, and the containing box is used for containing a to-be-used catheter body; the equipment base is arranged in the placement box, and the equipment base can ascend and descend in the placement box under the action of the lifting drive; the placing seat is arranged on one side of the upper end of the equipment seat; the limiting assembly comprises supporting rods inserted into the containing base, and the pipe body is wound around the outer sides of the multiple supporting rods; the smearing frame is arranged on the equipment base and located on one side of the containing base; the smearing assembly comprises a rotating ring erected on the smearing frame, a sponge pad is arranged in the rotating ring, and by arranging the smearing assembly and the smearing frame, manual smearing with a cotton swab can be replaced, so that efficiency is greatly improved, anesthetic or anesthetic ointment can be evenly smeared on the outer wall of the catheter, and the anesthetic ointment can be evenly smeared on the outer wall of the catheter; and the situation that the anesthesia effect is affected due to uneven smearing caused by manual smearing is avoided.

Description

technical field [0001] The present invention relates to the technical field of medical appliances, and more particularly, to a urinary catheter with anesthesia function. Background technique [0002] Anesthesia is generally not required for catheterization. Usually there will be slight discomfort and pain when the catheter is inserted. Most people can tolerate it. For very few patients who are difficult to insert a catheter or are particularly sensitive to pain, some anesthetic ointments can be applied to the urinary catheter or surface anesthetics can be injected into the urethra in advance to relieve pain. General anesthesia or epidural anesthesia are not used in the process of intubation. If intubation is particularly difficult for patients, such as urethral strictures, they need to be under anesthesia, but such patients are rare. The existing urinary catheter has a simple structure and a single function. When performing anesthesia, it is necessary to apply anesthesia o...

AI Technical Summary

Problems solved by technology

The existing urinary catheter has a simple structure and a single function. During anesthesia, it is necessary to smear anesthesia ointment on the outside of the catheter wall, which is troublesome. Alcohol disinfection is more troublesome, and the application is not enough, resulting in poor disinfection effect. Therefore, in order to better disinfect the catheter and apply anesthetic ointment, an auxiliary structure can be provided. In view of this, we propose an anesthetic function catheter
