Description

Urinary tube with anti-overflow operation channel

[0001] The present application relates to a medical device, in particular to a urinary tube with anti-overflow operation channel. BACKGROUND

[0002] Urinary tubes are very common medical devices in medical and nursing. In some cases, it is necessary to insert tools and instruments into the urinary tube for operation. However, the current urinary tubes do not have a dedicated instrument channel. Currently, the instrument is inserted through the urinary bag interface at the tail of the urinary tube, but this method cannot solve the problem of urine overflow. Because the insertion of rod-shaped instruments into the urinary tube requires the use of the water outlet, the water outlet is open, and the urine cannot be blocked. For example, some patients have difficulty inserting the urinary tube, so doctors may use a support rod to insert into the urinary tube through the urinary bag interface to increase the hardness of the urinary tube and assist in catheterization. However, when using the existing urinary tube, the urinary bag interface is occupied by the support rod and cannot be connected to the urinary bag. After the urinary tube is inserted into the bladder, urine will leak from the open urinary bag interface and contaminate clothing and bedding. Only after the support rod is removed and the urinary bag is connected to the urinary bag interface of the urinary tube, can the leakage of urine be eliminated. There is no urinary tube with an anti-overflow operation channel for placing instruments. TECHNICAL PROBLEM

[0003] The technical problem to be solved by the present application is that the current urinary tube does not have a dedicated operation channel for placing rod-shaped instruments with anti-overflow function. The current method of using the urinary bag interface for operation has the problem of uncontrollable spontaneous urine overflow after inserting the instrument. The present application provides a urinary tube with an anti-overflow operation channel. A instrument channel branch is provided at the center of the tail of the tube, and a dedicated leakage prevention structure is provided on the instrument channel branch. The leakage prevention structure allows the instrument to pass through while preventing urine from overflowing. The present application is a new medical device. TECHNICAL SOLUTION

[0004] The invention is a urinary catheter with an anti-overflow working channel. The urinary catheter has a tube head, a tube body and a tube tail from the head end to the tail end. The tube head has a drainage hole, and the tube tail has a urine bag interface. The working channel branch is in the middle of the tube tail and is in the same straight line direction as the tube body. In the initial straight state of the urinary catheter, the central axis of the working channel coincides with the central axis of the tube body. The tube tail has a urine bag interface branch on one side. The axis of the urine bag interface branch is not in the same straight line as the axis of the tube body. The urine bag interface branch is located on the side of the working channel in the tube tail. The working channel has a one-way valve and an elastic hole. The appropriate instrument tool can pass through the one-way valve and the elastic hole into the lumen of the working channel. The one-way valve and the elastic hole are used to prevent urine from overflowing when the instrument is inserted through the working channel branch into the urinary catheter. The one-way valve can have various structures and can be a detachable component or a non-detachable structure. The one-way valve can have one or more. The elastic hole can be provided on the detachable component of the urinary catheter or on the non-detachable structure of the urinary catheter. The elastic hole can also be combined with the one-way valve as one component. The elastic hole allows the rod-shaped instrument to pass through and tightly adhere to the instrument by elastic force to achieve the function of preventing overflow. The tube tail can also have other branches, including but not limited to a balloon water injection valve of a balloon urinary catheter and a perfusion interface for flushing water. The working channel can have a locking structure, including but not limited to a screw structure and a bayonet structure. The instrument placed in the urinary catheter can be fixed through the locking structure. Other components can also be installed on the outer opening of the working channel, including but not limited to a plugging cap, an adapter, a three-way switch, etc. The urinary catheter described in the invention can be various types of urinary catheters, including but not limited to a balloon urinary catheter, a flower-shaped urinary catheter, a disposable single-lumen urinary catheter, a double-lumen urinary catheter, a triple-lumen urinary catheter, a straight head urinary catheter and a curved head urinary catheter. Advantages

[0005] The invention has the advantages that the middle of the tube tail is provided with a special working channel, the working channel is in the same straight line as the tube body, and a straight rod-shaped instrument tool can be used. The working channel has a one-way valve and an elastic hole, which can prevent urine overflow and pollution. Because of the special working channel, the instrument tool does not occupy the urine bag interface and does not affect urine drainage. The instrument can be operated while the urine bag is connected to drain urine. There is no similar design to the invention, and the invention is an innovative application with practical significance. BRIEF DESCRIPTION OF DRAWINGS
