Description

External urinary catheter for men

Technical Field

The utility model belongs to the field of medical appliances, and particularly relates to an external urinary catheter for men.

Background

At present, many patients can not urinate spontaneously for a period of time due to general anesthesia operation or other reasons, at this time, a catheter needs to be placed on the patient, the traditional catheter is a pipeline which is inserted into the urinary bladder by urethra so as to drain urine, and is generally made of natural rubber, silicon rubber or polyvinyl chloride (PVC), the catheter can be inserted into the urinary bladder by urethra so as to drain urine, after the catheter is inserted into the urinary bladder, an air bag is arranged near the head end of the catheter to fix the catheter and is left in the urinary bladder, and the catheter is connected with a urine bag to collect urine; the catheter with the structure can be inserted into the urethra to enter the bladder when placed, so that a series of problems such as urethral injury or infection are easily caused, and more inconvenience is brought to nursing and rehabilitation of patients.

In the prior art, a device for realizing the urethral catheterization function in an external mode also appears, and CN105287084A discloses an external male urethral catheter and a preparation method thereof, wherein a sleeve body is adopted to cover the penis and an air bag is adopted to fix the penis, and the urethral catheter with the structure needs to ensure that the air bag is inflated to fix the penis, so that the condition of inflation of the air bag needs to be checked at any time, and the use is more complicated; the CN218391387U adopts the same technical scheme as the above technology, and adopts an air bag to inflate and fix the penis, so the same problem exists. CN113663144a discloses an external catheterization device for bedridden patients, which can be used only by wearing special wearing trousers for patients, and has high use cost and is difficult to widely popularize and use.

Therefore, whether to provide an external urinary catheterization device suitable for men is one of the problems to be solved in the art.

Disclosure of Invention

Aiming at a plurality of defects existing in the prior art, the utility model provides an external urinary catheter for men, which comprises a urinary catheter main body and a matched contrast card, wherein the urinary catheter main body is formed by combining an upper cover and a lower cover, both are made of silicone rubber materials, and the inner surfaces of the upper cover and the lower cover are preferably provided with antibacterial coatings.

The specific technical scheme adopted by the utility model is as follows:

the male external urinary catheter comprises a urinary catheter main body and a matched contrast card, wherein the urinary catheter main body is formed by combining an upper cover and a lower cover, both are made of silicone rubber materials, and antibacterial coatings are arranged on the inner surfaces of the upper cover and the lower cover.

The outer diameter of the upper cover is larger than that of the lower cover, a ring groove matched with the shape of the upper cover is arranged in the upper cover, and the ring groove can be tightly matched with the outer diameter of the lower cover, so that the upper cover and the lower cover are integrated;

in addition, the upper cover and the lower cover can be connected in a matched manner by adopting a mode of arranging a buckle, so that the upper cover and the lower cover are combined into a whole, and the upper cover and the lower cover can be specifically configured according to requirements.

In order to facilitate the separation of the upper cover and the lower cover, the upper cover is also provided with a lifting cover which is convenient to lift for nursing, cleaning and sterilizing; in addition, the upper cover is also provided with a ventilation port, in particular to a plug hole type design, which is convenient to open and close.

The bottom of the lower cover is provided with a lantern ring which is of a multistage and unequal-diameter structure, and the diameter of the bottommost lantern ring is gradually reduced to the diameter of the topmost lantern ring; as the penis is positioned at the horizontal position when lying in bed, the penis can be sleeved in the lower cover through the lantern ring when in use, and thus the upper half part of the penis can be completely arranged in the lower cover, thereby being convenient for collecting urine; the lantern ring cooperation contrast card of this application uses, is provided with not unidimensional draw-in groove on the contrast card that provides, and the size of draw-in groove corresponds with multistage unequal diameter structure on the lantern ring, at first through contrast card measurement determination patient penis size before the use, later selects suitable size part on the lantern ring, tailors and ensures not having the edges and corners and can overlap and use on patient penis after the surplus part. Due to the combination of the lantern ring and the contrast card, the catheter provided by the application can be suitable for various male patients, and various defects caused by the adoption of the air bag in the prior art are avoided; the further lantern ring is prepared from soft silica gel, and the thickness of the lantern ring is smaller than the wall thickness of the lower cover, so that the pressing of the penis can be greatly reduced, and the pressing injury is avoided;

a urine outlet is arranged on one side of the lower cover, which is far away from the lantern ring, and the urine outlet is connected with the urethral catheterization pipeline through an adapter; the collar with proper diameter just covers the penis in normal use, and the whole device is in an inclined state towards the urination port in use, so that the patient cannot leak from the collar after urination; the fixed orifices are arranged on two sides of the lower cover, and the fixed orifices can be used for threading when in use, so that the catheter is fixed on the body of a user, and the displacement of the catheter caused by turning over of a patient and the like is reduced.

This application is more convenient because having adopted upper cover and lower cover disconnect-type design, and when needs nursing the patient lower part of the body, need not get rid of the catheter, only need directly get rid of the upper cover, can carry out operations such as cleaning and disinfecting in the lower cover, because the patient is supine the time whole device down inclines just, cleaning and disinfecting liquid can directly be discharged through the catheterization pipeline and avoided leaking this moment, only need clean upper cover and lower cover inboard after washing and disinfecting to with the inseparable lock of two can, greatly reduced the degree of difficulty of nursing, improved patient's use experience.

As the antibacterial coatings are arranged on the inner surfaces of the upper cover and the lower cover, the possibility of infection can be reduced in the use process, and the recovery of patients is facilitated.

Compared with the prior art, the external urethral catheterization method is adopted, the external urethral catheterization device can be suitable for the needs of different male patients, nursing staff can conveniently wash and eliminate the penis through the split design of the upper cover and the lower cover, the operation difficulty is reduced, the risk of infection is reduced due to the fact that urethra injury is not caused, the use cost is greatly reduced due to the fact that patients do not need to wear special underpants, and the external urethral catheterization device can be widely popularized and applied.
