Portable urethral catheterization structureTechnical field
The invention belongs to medical apparatus and instruments processing technique field, particularly portable urethral catheterization structure.
Background technology
Current catheter top layer is not provided with lubricating layer, so existing catheter is entering urethra or not very convenient when sliding in storing bag.A kind of catheter is disclosed in the open file of publication number CN102029005B, the head of described catheter body is provided with into urine hole, afterbody is provided with mouth of urinating, this catheter also comprises nose sleeve, one end of described nose sleeve is provided with otch or aperture, the other end opens wide and is provided with defining flange, and nose sleeve energy pivot bush unit is originally external in catheter.This catheter surface is not provided with lubricating layer, makes catheter not be very smooth and easy when entering urethra, and the antibacterial in air cannot be prevented by catheter absorption and enter inside of human body thus.
Summary of the invention
The object of the invention is to arrange one deck lubricating layer on catheter, making catheter expedite slip of energy in urethra and storing bag.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: portable urethral catheterization structure, comprise urethral catheterization structural body, described urethral catheterization structural body comprises storing bag, described storing bag is provided with opening supports portion, the catheter covered by described storing bag is mounted with in described opening supports portion, described catheter surfaces externally and internally scribbles lubricant and forms lubricating layer, and described lubricating layer makes described catheter slide in described opening supports portion or in described storing bag or in described opening supports portion He in described storing bag.Lubricating layer is directly coated on catheter and catheter can be helped to enter urethra smoothly, and avoids the secondary pollution of catheter.Catheter smoothness when slip is without hindrance.
As preferably; described opening supports portion comprises pedestal; described pedestal offers and runs through described pedestal and the passage holding described catheter, described passage comprises the internal channel that fitted tightly by described storing bag and is arranged on storing bag 1 outer and protect the outer tunnel of described catheter.The catheter that can move freely is provided with in passage.Storing bag surrounding passes through hot sealing, so storing bag and described passage are also by fitting tightly after hot pressing.Pedestal is arranged to rhombus, can ensure the service life of storing bag.
As preferably, described outer tunnel is provided with operator guards; Described operator guards comprises and is socketed in soft protection pedestal on described outer tunnel and is arranged on described soft protection pedestal and the hard protective cap that can be separated with it.Soft protection pedestal fits tightly with catheter, and also fits tightly with outer tunnel, can also fit tightly with hard protective cap.Hard protective cap is provided with draw ring.
As preferably, described internal channel offers symmetrically arranged two through holes, described through hole cooperatively interacts and runs through described internal channel diametrically.Two through holes coordinate the thumb of human body and the shape of forefinger, storing bag can fix catheter by thumb and forefinger, then make catheter stretch out outer tunnel by slip storing bag.
As preferably, described catheter is close to by described storing bag, and lubricating layer seals between described passage and described catheter.In storing bag through sterile production out after do not have secondary pollution.Containing a small amount of air in storing bag, can by atmospheric pressure to being placed on being fixed in storing bag.Lubricating layer on catheter makes catheter mobile smooth and easy in storing bag.
As preferably, described catheter comprises the blind end be placed in described outer tunnel, on the horn-like export mouth be placed in described storing bag, the catheter body connecting described blind end and described blind end and export mouth and the described catheter body being opened near described blind end on be provided with catheterizing port.Blind end is provided with the arcwall face that conveniently can enter urethra.
As preferably, the internal diameter of described catheter increases from described blind end gradually to described export mouth.Catheter inside is hollow, the side thickness of the Thickness Ratio catheter of aforesaid arcwall face, and catheter can not be flattened by urethra active force when entering inside urethra.
Hold a portable urethral catheterization bag for described portable urethral catheterization structure, comprise packaging bag, in described packaging bag, be placed with described urethral catheterization structural body, a pair sterile gloves, at least one toilet paper and a bag sterilized cotton ball.
As preferably, described packaging bag sterile sealing is arranged.
In sum, the present invention realizes fast catheter inserting being carried out human body, and total is aseptic molding; whole catheter is enclosed in aseptic space; time directly take off hard protective cap, stretch out catheter and directly enter urethra, can not germ contamination be produced.Catheter outer surface arranges lubricating layer and makes the slip that catheter is unimpeded in opening supports portion or storing bag, and catheter inner surface arranges the outflow that lubricating layer makes urine smoothness; Storing bag is the plastic sheeting that two panels combines through hot pressing, then on a side of storing bag, is provided with mouthful support portion and coordinates lubricating layer that catheter in process of production can be made to enter storing bag smoothly.Soft protection pedestal fits tightly with catheter, plays position-limiting action, and play the effect of sealing with catheter outer wall close contact to catheter; Soft protection pedestal fits tightly with outer tunnel, prevents the gap between outer tunnel and catheter from the situation of side leakage can occur, and due to soft protection pedestal be made up of rubber, can also conveniently arrest; Soft protection pedestal fits tightly with hard protective cap, sealing catheter, and hard protective cap can be made to take off easily.Arranging of two through holes can facilitate stretching out of catheter.Storing bag is close to described catheter and is made do not have large quantity of air in storing bag; ensure to fit tightly out generation side leakage at soft protection pedestal with outer tunnel when urethral catheterization; and fixing effect is played to whole catheter, prevents in whole catheter indentation storing bag.The interior radial guiding outlet of blind end increases gradually, coordinates on catheter sidewall and is provided with catheterizing port, when urethral catheterization time, urine can produce an eddy current when entering catheter, the interior radial guiding outlet of blind end increases gradually, the eddy current that can make flows down fast, prevent the blocking of catheter, because the internal diameter of export mouth increases gradually, the flow of urine and flow velocity become very large, described ought urine now when flowing out from horn-like export mouth, a stronger support force can be provided to the sidewall of horn-like export mouth, this support force makes horn-like export mouth and internal channel fit closely, prevent urine from refluxing from internal channel, and the landing because urine storage is too many of storing bag can be prevented.The design of portable urethral catheterization bag meets individual and operates easily.
