Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap that functions as an external opening / closing valve for medical devices (eg, urethral catheter) placed in the human body.

[0002]

2. Description of the Related Art Conventionally, the following are examples of the use of medical devices for indwelling in human body.

Urinary incontinence and dysuria in women are often difficult to manage due to anatomical reasons of the external genitalia. For urinary disorders, drug therapy (ubretide, α blocker, etc.) and intermittent self-catheterization are currently widely used. For patients with urinary incontinence, drug therapy (anticholinergic drug, imipramine, ephedrine hydrochloride, α agonist, etc.), Balun catheter implantation method, pelvic floor muscle training method, intermittent self-catheterization method, urine collector, various diaper urination Laws, etc. have been devised and have achieved some results.

On the other hand, in patients with cerebrovascular accidents and spinal cord injuries, there are cases in which the reaction of the drug is insufficient or the hand is inadequate, so that the operation of the catheter or the like cannot be performed sufficiently and the patient is out of the indication. Many. In particular, for females with moderate to hemiplegic and upper spinal cord injury (damage to the 7th cervical vertebrae and above), the only available urinary management methods are bladder fistula and diaper urination.

Further, when using a urethral catheter, urine adheres to the cap and leaves fine crystals when dried. When crystals are attached to the contact surface of the cap, irregularities are formed and urine leaks between them.

[0006]

The problem to be solved by the present invention is, for example, in a woman who has difficulty in urinating with residual urine, or in urinary incontinence who is urinating a bladder fistula or diaper. To provide a cap for an indwelling medical device that is easy to operate, such as excretion of urine and accumulation of urine even in a poorly sophisticated case, and does not easily cause urine leakage even if irregularities are formed by crystals of urine. .

[0007]

The magnetic cap for a medical instrument to be placed on a human body according to the present invention is a cap for a medical instrument to be placed on a human body in which a hinge portion is connected to a connection plug body to connect a lid body to the body. The above-mentioned problem is obtained by integrally molding the number part and the lid from the same synthetic resin material, attaching an engaging member made of a flexible material to the center of the inner surface of the lid, and attaching a drawstring to one end of the lid. Has been resolved.

An annular magnet is fixed on the upper surface of the connection plug body, and the annular magnet is fixed by surrounding the engaging member on the inner surface of the lid. The diameter of both magnets is 5 to 15 mm and the thickness is 0.
Set to 5 to 5 mm and set the magnetic flux density to 100 to 2000
It may be set to Gauss and the magnetic poles of the contact surfaces of both magnets may be installed opposite to each other.

One of the two annular magnets is made of a ferromagnetic material (for example, iron, samarium, nickel,
It can be replaced with an annular ferromagnet made of cobalt, ferrite, etc.). In this case, the diameter of the ring magnet is 5 to
It is preferable that the thickness is set to 15 mm and the thickness is set to 0.5 to 5 mm, the magnetic flux density is set to 100 to 2000 Gauss, and the diameter of the annular ferromagnetic body is set to 5 to 15 mm and the thickness is set to 0.1 to 10 mm. .

[0010]

With the cap for a medical instrument for indwelling of the human body of the present invention, even when a patient with a poor hand skill is used, when the pulling string is hooked on the finger or palm of the hand and the pulling string is pulled toward the connecting plug body, The lid body covers the connection plug body by the elastic restoring force of the numbered portion, and the engagement member airtightly engages with the peripheral edge of the outlet of the connection plug body. At this time, even if the lid body bends to some extent and moves, the engagement member on the inner surface of the lid body is guided to the outlet of the connection plug body to engage the lid body at the regular position. Therefore, the lid securely engages with the connection plug body, and even if a gap is formed between the contact surfaces of the two, the engaging member engages with the discharge port in an airtight manner, so that leakage can be prevented.

When the lid is opened, if the pulling string is pulled in the opposite direction to the above, the lid is pulled open against the elastic resistance of the hinge portion, and when the predetermined angle is exceeded, the hinge is pulled. The back ring of the turn keeps the lid completely open.

When magnets are attached to the connection plug body and the lid body, if both magnets are brought close to each other, the magnets attract each other accurately at a predetermined position by the attraction action.

Even when a magnet is attached to either the connection plug body or the lid and a ferromagnetic material is attached to the other, the same effect as above can be obtained. Since the annular ferromagnetic body can be made thin, the weight of the entire cap can be reduced.

The magnetic flux density of one or both magnets is 100 to 2
Since it is set to 000 gauss, the mutual attraction force of one or both magnets is considerably strong and does not come off naturally while wearing the cap. However, when the patient wants to open the cap, it can be easily opened by hooking the drawstring on the finger or palm as in the cap closing operation.

Since the connection plug and the entrance / exit of the medical instrument for indwelling the human body can be detachably connected, it can be widely used for instruments of the same type or different types.

The magnet has a diameter of 5 to 15 mm and a thickness of 0.5 to
The diameter is set to 5.0 mm, and the diameter of the annular ferromagnet is 5 to 1
Since the thickness is set to 5 mm and the thickness is 0.1 to 10 mm, the size is relatively small and the cap itself does not feel foreign matter when worn.
