Novel painless super-smooth antibacterial catheter

Abstract

The invention discloses a novel painless ultra-smooth antibacterial catheter which structurally comprises an air bag, a catheterization device, a catheter body, a sampling tube, a connecting tube, an inflation water injection tube and a urination catheter.When the novel painless ultra-smooth antibacterial catheter is used and when a doctor carries out intubation, a sleeving opening is matched with the catheter body and extends into the bladder through the urethra, normal saline is injected into the air bag through the inflation water injection tube, and the catheter body is inserted into the air bag through the urine injection tube; when catheterization is carried out, urine flows into the catheter body through the butt joint opening and makes contact with the flow slowing assembly, the flow slowing assembly plays a role in buffering and speed reduction on the urine, the urine can stably flow to the movable expansion piece in the catheter body under the action of the multiple inclined sliding plates, and therefore the catheter can be conveniently and rapidly guided. When the urine flows out, the movable expansion piece is opened downwards under the downward impact force of the urine, the urine flows to the guiding-out assembly along with the movable expansion piece, blood clots in the urine are treated through the guiding-out assembly, and the urine can be discharged outwards in time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel painless ultra-smooth antibacterial urinary catheter. Background technique [0002] A urinary catheter is a device that inserts a urinary catheter into the bladder through the urethra to drain urine. Therefore, urinary catheters are widely used in the medical field. After surgery, when the patient is inconvenient to urinate, urinary catheterization is required. It is to guide the urine in the bladder to the outside of the body to prevent the patient from holding back urine and the bladder is swollen. It needs to use a urinary catheter. When using a urinary catheter, the areas that need to be improved: [0003] When the existing urinary catheter is used to guide the patient, the end of the tube will be inserted into the patient's urethra and inserted into the bladder under normal conditions. Treatment, when catheterization is performed on urinary patients after su...

AI Technical Summary

Problems solved by technology

[0003] When the existing urinary catheter is performing catheterization on a patient, under normal circumstances, the end of the catheter will extend into the patient's urethra and be inserted into the bladder, and the connecting member is connected to the connecting tube to effectively catheterize the urinary patient after surgery. Treatment, when catheterizing urinary patients after surgery, because some urinary patients will experience bleeding after surgery, if the amount of bleeding is large, a large blood clot will form in the bladder in a short period of time, catheterization During the discharge of urine from the patient's bladder, the blood clot will also enter the catheter through the docking guide with the urine. Due to the large volume of the blood clot, it will be blocked when it is discharged, so that the urine in the bladder will be blocked. The urine cannot be discharged in time, causing the patient's bladder to store too much urine and causing certain damage to it.
