Abstract

The utility model relates to a urinary catheter with a lantern head, which is used for clinically treating patients. The utility model is composed of a catheter, the notch of an end head and a pull thread fixed on one end of the notch with sealing and passing through the other end along the catheter. The utility model has simple structure, convenient use and safety and is helpful for the patients and cares. The popularization and application are popular among the patients and the medical persons.

Description

Urinary catheter

This utility model relates to a kind of invalid lantern head catheter for the treatment of clinically.

Urethral catheterization is that treatment urine difficulty and urine stop up requisite a kind of method; urethral catheterization at present generally is catheter and the Foley catheter that adopts rubber to make; its version is to open a catheterizing port in catheter one end; during use; catheter is inserted intravesical; blended rubber cloth is fixed on the human body; because inserting intravesical, catheter is straight tube-like; thereby drop out in use regular meeting; cause urethral catheterization failure or reappose, cause suffering, also cause trouble to the medical personnel to patient; use inconvenient; and with adhesive plaster catheter is fixed on the human body, there is a few patients can produce allergic phenomena, be as good as the misery that has increased patient; therefore, the straight pipe type catheter remains further to be reformed and innovation.

The purpose of this utility model is exactly to provide a kind of new lantern head catheter at the deficiency of straight pipe type catheter.

The purpose of this utility model is achieved like this, the rubber tube that the system catheter is used is opened otch along the pipe symmetry on termination 0.5cm place tube wall, and along adorning a backguy in inherent termination, during use, backguy in the pulling pipe after inserting bladder, insert intravesical part and just be the lantern shape through otch, the urine outlet that urine just forms with otch automatically flows out external through conduit, reaches the purpose of urethral catheterization.

This utility model is simple in structure, and is easy to use, and safe, firm, urethral catheterization is effective, welcome by patient and medical worker.

Below in conjunction with accompanying drawing structure of the present utility model and operating position are elaborated.

Fig. 1 is a backguy tension structure chart of the present utility model.

Fig. 2 is backguy relaxed configuration figure of the present utility model.

By shown in Figure 1, this utility model is to have long otch 3 at an end 0.5-1.00cm place of conduit 1, it is long that otch is generally 1.5cm, it between two otch lantern muscle 4, termination sealing by otch 3, otch has symmetric two at least, preferably symmetry is cut the long joint-cutting of 4 1.5cm, adorns a fixedly backguy 2 along conduit 1 on a termination of sealing, and No. 10 surgical threads are adopted in backguy, and be longer than conduit, promptly in managing, pass, during use, for ease of fixedly backguy, have backguy perforation 5 on the tube wall of conduit other end, backguy is passed in the hole, when backguy 2 tensions, inserts intravesical head notch portion and is the lantern shape, incision becomes catheterizing port, so claim lantern head catheter.

Using method of the present utility model is as common (such as straight pipe type) catheter, just in use, when catheter inserts bladder and have urine to flow out, again catheter is inwardly inserted 2-3cm, and about 0.5cm is pulled out in backguy, make cutting part be the lantern shape, be pulled outwardly catheter more gently, when feeling resistance is arranged, backguy 5 passed upwards warpage through boring a hole, be fixed on the tube wall with adhesive plaster 6, when urethral catheterization finishes, unclamp backguy, the lantern shape that conduit expands recovers present situation automatically by the elasticity of conduit self, catheter is straight tube-like, as shown in Figure 2, just conduit can be extracted, if reuse, available tap water is rinsed well, is immersed in the sterilization stand-by.

By above situation as can be seen, being the lantern head owing to the intravesical conduit in the urethral catheterization process, thus can not deviate from automatically, even the unconscious tractive of patient, can not deviate from yet, and conduit expand the place closely contact with internal urethral orifice, be not prone to the leakage of urine phenomenon, do not need the reuse immobilization with adhesive tape on people's skin yet, convenient nursing, be beneficial to patient, fine through clinical trial result, welcome by patient and medical personnel.

Claims

1, a kind of lantern head catheter that constitutes by conduit and otch, an end that it is characterized in that conduit (1) has long otch (3), it between two otch lantern muscle (4), termination sealing by otch (3), pass in managing along conduit (1) fixedly backguy of dress (2) on a termination of sealing, during backguy (2) tension, notch portion is the lantern shape.

2, lantern head catheter according to claim 1 is characterized in that the end 0.5-1.0cm place of said long otch (3) at conduit (1), and long is 1.5cm.

3, lantern head catheter according to claim 1 and 2 is characterized in that said otch (3) is that symmetry is cut the long joint-cutting of 4 1.5cm.

4, lantern head catheter according to claim 1 is characterized in that having on the tube wall of conduit (1) backguy perforation (5).
