Abstract
The utility model provides a medical catheter, belonging to the medical apparatus technical field, comprising a nonmetal tube (1) and a tube core (2), the front end of the nonmetal tube (1) is round smoothly enclosed, the tube wall at the back of the enclosed end is arranged with a urine guide hole (3), the nonmetal tube (1) is provided with an internal solid tube core (2) that the inner diameter is smaller than the nonmetal tube (1), the front end of the tube core (2) reaches the sealed bottom of the nonmetal tube (1), the rear end is outside the nonmetal tube (1) and connected with a handle (4). The utility model has the advantages that the urine problem of the patient that the urine channel is narrow, the tube has part of intensity of the metal catheter and the suppleness of the rubber catheter, the damage of the urine channel is decreased, the tube could be left in the bladder after the tube core is pulled out, the front end is arranged with scale, the inserted urine channel length could be accurately confirmed, and the operation is easy.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of medical catheter.
Background technology
Prostatic hyperplasia is elderly men patient's a commonly encountered diseases, and this disease often causes dysuria, and lower urinary tract obstruction causes acute urinary hesitancy, needs urgent urethral catheterization, and this kind patient is because prostatic urethra is narrow, swelling, general catheter commonly used are difficult to insert.And the catheter that uses clinically at present mainly contains two kinds: a kind of is the soft catheter that elastomeric material is made, because himself softer very difficult insertion bladder, sometimes even can't insert; Another kind is rigid metal urethral catheter, and is bigger to injury of urethra when metal urethral catheter inserts, and can only be used for interim urethral catheterization, and can not in urethra, place for a long time, very inconvenient to patient like this, and generally be to have rustless steel to be made, cost height, not easy cleaning and sterilization.And how long these two kinds of catheters insert urethra on earth when clinical manipulation, needs the doctor to lean on working experience for many years to estimate, so not only lost time but also bring unnecessary trouble to the operator.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and integrated cost is low, sterilization and processing ease, and convenient the insertion and delay can accurately determine to insert the medical catheter of length
The purpose of this utility model is achieved in that this medical catheter is made up of nonmetal conduit and tube core, the front end of nonmetal conduit is slick and sly sealing, be provided with the urethral catheterization hole on the tube wall of position after a while at blind end, be provided with the solid tube core thinner slightly than nonmetal catheter diameter in the inside of nonmetal conduit, the front end of tube core reaches the sealed bottom of nonmetal conduit, and end is the outside of nonmetal conduit and be connected with handle.On nonmetal catheter proximal end outer wall, be provided with scale mark, be convenient to grasp easily the insertion length of control catheter.
When specifically using this utility model, can be according to actual needs, tube core is suitably crooked, the conduit that will have tube core again inserts by the metal intubation, can enter bladder by urethral stricture portion smoothly, behind fixing nonmetal conduit, withdraw from its tube core, then nonmetal urinary catheter in is in bladder.
Advantage of the present utility model: solved urethral stricture patient's a urethral catheterization difficult problem, the part intensity of metal urethral catheter is promptly arranged, the flexibility of rubber urinary catheter is arranged again, promptly be easy to insert, can reduce damage again, can keep somewhere bladder again after extracting tube core simultaneously out to urethra.Because front end is provided with scale mark, can accurately determine to insert urethral length simultaneously, easy to operate.Conduit is disposable use, safety and sanitation, because tube core is solid, so be easy to clean and sterilization, tube core can repeatedly use.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
The specific embodiment
Make this utility model with reference to accompanying drawing: this medical catheter is made up of nonmetal conduit 1 and tube core 2, the front end of nonmetal conduit 1 is slick and sly sealing, be provided with urethral catheterization hole 3 on the tube wall of position after a while at blind end, be provided with than the thin slightly solid tube core 2 of nonmetal conduit 1 internal diameter in the inside of nonmetal conduit 1, the front end of tube core 2 reaches the sealed bottom of nonmetal conduit 1, and end is the outside of nonmetal conduit 1 and be connected with handle 4.On nonmetal conduit 1 front end outer wall, be provided with scale mark 5, be convenient to grasp easily the insertion length of control catheter.Nonmetal conduit 1 material can select for use rubber, silica gel, flexible plastic etc. to make, and tube core 2 available metals or alloy and other hard material are made.
Claims (2)
1. medical catheter, form by nonmetal conduit (1) and tube core (2), the front end that it is characterized in that nonmetal conduit (1) is slick and sly sealing, be provided with urethral catheterization hole (3) on the tube wall of position after a while at blind end, be provided with the solid tube core (2) thinner slightly than nonmetal conduit (1) internal diameter in the inside of nonmetal conduit (1), the front end of tube core (2) reaches the sealed bottom of nonmetal conduit (1), and end is the outside of nonmetal conduit (1) and be connected with handle (4).
