Description

Visual Intermittent Catheter with Lighting Function

technical field

The invention relates to the technical field of urinary catheters, in particular to a visual intermittent urinary catheter with lighting function.

Background technique

Neurogenic bladder (neurogenic bladder) refers to the damage of the central and peripheral nerves related to urination, which causes a common but difficult to treat urinary dysfunction disease. Dysuria, urinary retention and urinary incontinence are the most common clinical symptoms. If not treated in time, it often causes vesicoureteral reflux, hydronephrosis and urinary tract infection, which can easily lead to upper urinary tract damage and renal failure and death. At present, no effective treatment method has been found. Conservative treatment is the most important treatment method at present, that is, to avoid excessive bladder filling and expansion through intermittent catheterization, to regularly discharge residual urine, to increase bladder compliance, and to restore the low-pressure urine storage function of the bladder. Protect the upper urinary tract. It is easy to operate, economical, feasible, and has few complications. It has been recommended by the International Continence Association as the first choice for emptying the bladder, and it has been widely used clinically. However, for female patients, due to the particularity of the congenital anatomy of the external opening of the urethra, when the existing catheter is used for self-catheterization, the opening of the urethra cannot be found quickly and accurately, and it is easy to have difficulty in insertion.

Contents of the invention

The invention provides a visible intermittent urinary catheter with lighting function, aiming to solve the problem that the existing urinary catheter is not conducive to self-catheterization of female patients.

To achieve the above object, the present invention can take the following technical solutions:

The visible intermittent urinary catheter with lighting function of the present invention includes a catheter, one end of the catheter is a spherical head structure, a catheter side wall near the end of the spherical head is provided with a catheter side wall, and the other end of the catheter is A urine bag connector is provided, and a connecting plate is arranged on the urine bag connecting head, and a fixed plate perpendicular to the conduit is movable on the connecting plate, and an LED light is arranged on the side of the fixed plate facing the spherical head , the LED lamp is surrounded by a guide lampshade that directs the light to the spherical head, and the fixed plate is also provided with a convex mirror located above the LED lamp for reflecting objects at the spherical head into the patient's eyes.

The LED lamp is electrically connected with the battery arranged in the fixed board and the power switch arranged on the fixed board through wires.

Both the LED lamp and the convex mirror are slidably connected to the vertical chute provided on the fixing plate through the bottom slider.

Both the LED light and the convex mirror are connected to the bottom slider through universal joints.

The fixing plate is inserted into the installation groove opened on the top of the connecting plate and locked by a buckle.

There are two catheter holes.

The visual intermittent urinary catheter with lighting function provided by the present invention has a simple structure, is easy to manufacture and use, has low cost and strong practicability, and can help female patients find the urethra quickly and accurately through the combined use of light sources and reflectors mouth, which greatly facilitates self-catheterization and meets clinical needs.

Detailed ways

As shown in Figure 1, the visible intermittent urinary catheter with lighting function according to the present invention includes a catheter 1 made of natural rubber, silicone tube or polyvinyl chloride material, and one end of the catheter 1 is a spherical head structure, On the side wall of the catheter close to one end of the spherical head, there are two catheterization holes 2 which are not arranged axially, and the other end of the catheter 1 is provided with a urine bag connector 3 . During normal use, the urine bag connector 3 is connected to the urine bag, and urine can enter the catheter 1 through the catheter hole 2 and be collected by the urine bag.

In order to facilitate self-catheterization of female patients, a connecting plate 4 of hard plastic material as shown in Figure 2 is fixedly sleeved at the end of the above-mentioned urine bag connecting head 3, and the top of the connecting plate 4 is connected with a fixed plate 5 perpendicular to the catheter 1. An LED lamp 6 with a guide lampshade 7 and a convex mirror 8 above the LED lamp 6 are installed on the front panel of the fixing plate 5 (ie, the side facing the spherical head). The above-mentioned LED lamp 6 is electrically connected with the battery 9 arranged in the fixed plate 5 and the power switch 10 arranged on the back of the fixed plate 5 through wires to form a closed circuit. When inserting the urinary catheter, the patient can turn on the LED light 6 to let the light shine directly on the spherical head of the catheter, and observe the position of the urethral orifice through the convex mirror 8 with magnifying and reflecting functions, and accurately insert the catheter 1 from the urethra into the bladder Inside.

Because the patient's height and weight are different, the catheterization operation position is different, therefore, as shown in Fig. The slot 11 is slidably connected; further, the LED lamp 6 and the convex mirror 8 can be connected to the bottom slider through a universal joint. When in use, the position and angle of the LED lamp 6 and the convex mirror 8 can be adjusted according to the actual situation to ensure that the light of the LED lamp 6 directly hits the spherical head, and at the same time, the objects at the spherical head are clearly reflected into the eyes of the patient. It is convenient for patients to self-catheterize.

The above-mentioned catheter 1 and urine bag connector 3 can be disposable products, while the fixed plate 5 and the connecting plate 4 adopt a flexible connection mode, so that the fixed plate 5 and the lighting circuit on it and the convex mirror 8 can be reused, thereby achieving The purpose of cost saving. Specifically, an installation slot 12 with buckles is provided on the top of the connecting plate 4, so that the fixing plate 5 and the connecting plate 4 are plugged and connected, and locked by the buckles. In addition, the fixed plate 5 and the connecting plate 4 can also adopt other common flexible connection methods.
