Abstract

The utility model relates to a surgical apparatus, particularly a casing catheter of an indwelling urinary catheter, which comprises a catheter and the connecting part of the catheter, wherein the arc-shaped connecting part is connected to the part of catheter wall at the front end of the catheter, a hole at the front end of the catheter is exposed from the connecting point and a concave longitudinal channel is arranged on the connecting part. The diameter of the longitudinal channel is gradually reduced in the process of extending to the utmost front end of the connecting part, when the longitudinal channel arrives at the utmost front end, the longitudinal channel becomes into an obtuse smooth circular head. The utility model has the advantages of simple structure, safe and convenient operation, low using cost, etc., a thin and soft urinary catheter can be conveniently inserted into a bladder, the urinary catheter is retained in the bladder to reserve the urethral catheterization, and patients' pain is greatly reduced.

Description

The indwelling catheter pipe-in-pipe

This utility model relates to a kind of surgical instruments, relates in particular to the sleeve pipe of indwelling catheter.

Prostatic hyperplasia or other diseases are caused the long-term urokinase road-blockage, the renal function obvious damage, serious urinary tract infection or the patient that acute urinary retention takes place, to remove blocking of urinary tract with the method for indwelling catheter earlier, but part patient's urethral catheterization is difficulty quite, the method that solves is to adopt bladder stoma, and this method can increase patient's misery; Do not having the hospital of bladder stoma, can only adopt acupuncture suction urine temporarily to solve patient's misery, giving treatment to a patient in this way and might accidentally injure blood vessel and cause complication such as hematoma behind the pubis, infection; Some patient promptly enables to insert catheter, and is also thick hard uncomfortable or stimulate urethra to cause urethritis because of catheter, though and metal urethral catheter can insert urethra, do not have the function of indwelling catheter, if use repeatedly, can cause injury of urethra and urinary tract infection; Weak or merge the prostatic hyperplasia patient of vitals pathological changes such as the heart, lung, kidney for those advanced ages, obviously the excision prostate of should not having an operation, more need during urine retention to make long-term retention catheterization, but thin and soft catheter can't directly insert bladder with thin and soft catheter.

The purpose of this utility model is a kind of sleeve pipe that can indwelling catheter of design, for those dysuria and the patient that urethral catheterization is failed, it can insert bladder to thin and soft catheter easily, and with urinary catheter at intravesical, retention catheterization greatly alleviates patient's misery.

The technical solution of the utility model is, a kind of indwelling catheter pipe-in-pipe, the linking part that comprises pipe and pipe, it is characterized in that: the telescopic pipe of indwelling catheter is a hollow pipe, arcual linking part is engaged on the part tube wall of pipe front end, expose at joining place in the hole of pipe front end, become a slotted eye, the arcual part that is connected goes up the stringer raceway groove that design has a spill, the diameter of stringer raceway groove reduces in extending to the process foremost that is connected part gradually, becomes the smooth round end of blunt shape to foremost the time.

The utility model has the advantages that 1, simple in structure, easy-to-operate, use cost be low; 2, because sleeve-shaped, length, the radian of indwelling catheter is consistent with divulsor, and sleeve pipe can insert bladder easily, at intravesical, and can not damage urethra to urinary catheter in, alleviate patient's misery.

Below in conjunction with accompanying drawing this utility model is described in further detail.

Fig. 1 is the telescopic structural representation of this utility model indwelling catheter.

Fig. 2 is the left view of Fig. 1.

As seen from the figure, this utility model indwelling catheter pipe-in-pipe comprises pipe 1, the arc that is connected mutually with the part tube wall 4 of pipe 1 front end is connected part 2.Pipe 1 is a hollow pipe, in pipe 1, can insert catheter, expose at joining place in the hole 3 of pipe 1 front end, become an oval-shaped hole, be connected part 2 and be designed to arc, the stringer raceway groove 5 that a depression is arranged on the arcual linking part 2, stringer raceway groove 5 mainly is the insertion that makes things convenient for catheter, the diameter of stringer raceway groove 5 diminishes in extending to the process foremost that is connected part 2 gradually, to be connected part 2 foremost the time then form the smooth rounded nose 6 of a blunt shape, this slick rounded nose 6 helps sleeve pipe and successfully inserts intravesical, and can not damage urethra.

When using this utility model indwelling catheter pipe-in-pipe to give patient's urethral catheterization, carry out disinfection with the indwelling catheter pipe-in-pipe and than the smaller catheter of the telescopic internal diameter of indwelling catheter earlier, lubricated again, then the indwelling catheter pipe-in-pipe is inserted intravesical by the urethral dilatation method, just can see that urine flows out from the telescopic tail end of indwelling catheter, catheter after will lubricating again all inserts in the indwelling catheter pipe-in-pipe from the telescopic tail end of indwelling catheter, urine just flows out in catheter, at this moment can extract the indwelling catheter pipe-in-pipe, according to catheter high scale labelling catheter is fixed, and be retained in intravesical, retention catheterization.Through clinical trial, use this utility model indwelling catheter pipe-in-pipe to give patient's urethral catheterization, can insert bladder to thin and soft catheter easily, retention catheterization greatly alleviates patient's misery.

This utility model indwelling catheter pipe-in-pipe adopts compo pipe, copper pipe, stainless steel tube or plastic tube.

This utility model indwelling catheter pipe-in-pipe also can be retained in intravesical with the pigtail silica gel tube, retention catheterization.

Claims

1, a kind of indwelling catheter pipe-in-pipe comprises the linking part of pipe and pipe, and it is characterized in that: pipe is a hollow pipe, is connected part and is engaged on the part tube wall of pipe front end.

2, indwelling catheter pipe-in-pipe according to claim 1, it is characterized in that: expose at joining place in the hole of pipe front end, becomes a slotted eye.

3, indwelling catheter pipe-in-pipe according to claim 1, it is characterized in that: be connected the partial design camber, at the arcual stringer raceway groove that a spill is arranged on the part that is connected, the stringer raceway groove reduces in extending to the process foremost that is connected part gradually, to be connected partly foremost the time become the rounded nose of blunt shape.
