Description

Urethra positioner for female self-catheterization

Technical Field

The utility model belongs to the technical field of medical equipment, and particularly provides a urethra positioner for female self-catheterization.

Background

For patients with neurogenic bladder or other reasons that are unable to urinate autonomously, and for patients lying in bed for a long period of time, a urinary catheterization treatment may be required, in particular, by inserting a catheter into the bladder through the patient's urethra, leading out the urine in the bladder.

For patients who do not need hospitalization and need a catheter, besides long-term indwelling of the catheter (which is easy to induce various complications such as urinary system infection and vesical calculus), intermittent catheterization is the longest means for treating urination dysfunction diseases, and the catheter is generally inserted into the bladder by family members or by themselves, urine is discharged, and then the catheter is pulled out. Because the female urethral orifice and the vaginal orifice are relatively close, and the patient himself is not easy to find, it becomes very difficult for the female patient to find the urethral orifice and insert the self-catheter into the urethra when intubating himself. Particularly female patients who just begin to catheterize themselves, finding the urethral orifice is a very troublesome clinical problem. Therefore, an auxiliary device is needed to assist female patients to locate the urethral meatus, and then to smoothly self-catheterize.

The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.

In a first embodiment of the utility model:

as shown in fig. 1-3, a urinary tract locator for female self-catheterization includes a locator body 100 and two reflector assemblies 200. Wherein, the locator body 100 is used for realizing the positioning of the urethral orifice by the patient; the reflector assembly 200 is used to assist the patient in manipulating the positioner body 100 and to assist the patient in inserting the urinary catheter into the positioning aperture 120 in the positioner body 100.

Furthermore, one skilled in the art can also provide a urethral positioner having only one mirror assembly 200 as desired.

As shown in fig. 1 and 2, the locator body 100 includes a front portion 110, a locating hole 120, and a grip portion 130. The front portion 110, the positioning hole 120 and the holding portion 130 are sequentially distributed along the direction from the top to the tail of the positioner body 100.

As shown in fig. 1, the front portion 110 gradually contracts in a direction from the tail end to the top end of the locator body 100 such that the front portion 110 forms a locating point 111 at the head end of the locator body 100, the locating point 111 being for abutting the clitoris of the patient. Those skilled in the art will appreciate that the patient can clearly feel when the anchor point 111 collides against the clitoris because there are many nerve endings at the clitoris.

Further, the positioning hole 120 is provided as a circular hole, and the diameter of the positioning hole 120 ranges from 5 mm to 15 mm. For example, 5 mm, 8 mm, 10 mm, 12 mm, 13 mm, 15 mm, etc. The distance from the axis of the positioning hole 120 to the positioning point 111 ranges from 20 mm to 30 mm. For example, 20 mm, 22 mm, 25 mm, 28 mm, 30 mm, etc.

Preferably, the diameter of the positioning hole 120 is set to 10 mm, and the distance from the axis of the positioning hole 120 to the positioning point 111 is set to 25 mm.

Since the diameter of the existing urinary catheters used for females does not exceed 9 mm, and the average distance from the female clitoris to the urethral orifice is 25 mm; the distance from the axis of the positioning hole 120 to the positioning point 111 can be appropriately reduced or increased if the diameter of the positioning hole 120 is made larger.

As can be seen from fig. 1 and 2, both ends of the positioning hole 120 in the axial direction are provided with flaring structures 121 to prevent a distinct edge from occurring on the side of the positioning hole 120 that is attached to the patient, causing discomfort to the patient. At the same time, the flared structure 121 on the side of the positioning hole 120 remote from the patient's body also allows the catheter to be easily slid into the positioning hole 120.

Further, one skilled in the art may set only one end of the positioning hole 120 in the axial direction as the flaring structure 121 as needed.

As can also be seen in fig. 1 and 2, the grip 130 is small at the middle and large at the ends, which can facilitate the patient's grip on the positioner body 100.

As shown in fig. 2 and 3, the locator body 100 is provided in a flat plate-like structure and includes a first section 101 and a second section 102. The front portion 110 and the positioning hole 120 are both located on the first section 101, and the grip 130 is located on the second section 102. The first section 101 is inclined in a first direction toward a direction away from the second section 102, and the second section 102 is inclined in a second direction toward a direction away from the first section 101.

Wherein the first direction and the second direction are opposite, and both the first direction and the second direction are parallel to the axial direction of the positioning hole 120.

Further, the positioner body 100 is entirely made of a skin-friendly material such as rubber, silicone, or the like. Alternatively, the positioner body 100 can flex slightly as a whole when subjected to an external force, so that the positioner body 100 better conforms to the clitoris portion and the urethral meatus site.

As shown in fig. 1 to 3, the mirror assembly 200 includes a mirror 210 and a link arm 220, the link arm 220 being connected to the mirror 210 through one end thereof, and the link arm 220 being connected to the rear end of the positioner body 100 through the other end thereof. Preferably, the connection arm 220 is detachably connected to the rear end of the positioner body 100 through the other end thereof to facilitate the patient's removal of the mirror assembly 200 for cleaning and sterilizing the positioner body 100. Specifically, a slot is provided on one of the connection arm 220 and the positioner body 100, and a fixing post is provided on the other of the connection arm 220 and the positioner body 100, the fixing post is plugged together with the slot, and is interference fit.

The mirror 210 includes a frame (not shown) and a mirror body, so that the mirror 210 is fixedly connected to the connection arm 220 through the frame. Preferably, both sides of the mirror body can reflect light, so that a user can use the corresponding side according to actual needs.

Further, although not shown in the drawings, the connection arm 220 includes a wire deformable by force and a flexible case wrapped outside the wire so that the connection arm 220 can be arbitrarily bent by the wire and maintained in a posture after bending to facilitate the use of the scope by a patient. The flexible housing serves to optimize the appearance of the connecting arm 220.

The method of using the urethral locator in the first embodiment of the utility model will be described with reference to fig. 1.

The patient first holds the grip 130 with one hand and then places the urinary tract locator behind the clitoris and moves forward to separate the labia by the anterior portion 110 to prevent the labia from occluding the meatus. When the urinary tract locator is moved to a position where the anchor point 111 abuts the clitoris, the movement is stopped. The locator body 100 is then aligned so that the locating holes 120 are aligned with the urethral meatus. At this time, the user may appropriately adjust the mirror assembly 200 so that the positioning hole 120 is observed through the mirror 210. To this end, the patient inserts the catheter into the positioning hole 120 and inserts the catheter into the urethra.

After the catheter is inserted in place, the patient can slide the urinary tract locator out of the tail end of the catheter.

Further, to promote patient comfort, the patient may apply a dose of lubricant to the surface of the first section 101 of the positioner body 100 prior to use.

Based on the foregoing, one skilled in the art will appreciate that the urinary tract locator of the present utility model can assist the patient in inserting the urinary catheter into the urethra and bladder by himself, facilitating the catheterization of the patient.

In a second embodiment of the utility model:

as shown in fig. 4, compared with the first embodiment, the side-slip channel 140 is further provided on the positioner body 100 in this embodiment. The side sliding passage 140 penetrates the retainer body 100 in the axial direction of the positioning hole 120. Meanwhile, the sideslip passage 140 extends from the positioning hole 120 to the left or right side of the positioner body 100 in the radial direction of the positioning hole 120, so that the sideslip passage 140 also penetrates the positioner body 100 in the radial direction of the positioning hole 120.

The side-slip channel 140 can allow the urinary catheter to slide out of the positioning hole 120 in a radial direction of the positioning hole 120. Thus, the urinary tract locator of the present embodiment is capable of allowing a larger tail catheter (particularly a two-lumen catheter and a three-lumen catheter) to slide out of the locating hole 120 from the side-slip channel 140 after insertion into the urethra, relative to the first embodiment. In other words, the urinary tract locator of the present embodiment can be separated from the urinary catheter in the locating hole 120 by the sideslip passage 140.

Preferably, the width of the sideslip channel 140 is slightly less than the diameter of the pilot hole 120, e.g., the width of the sideslip channel 140 is 1 millimeter, 1.5 millimeters, 2 millimeters, etc., less than the diameter of the pilot hole 120 by any feasible value. To avoid accidental slipping of the catheter out of the side-slip channel 140 during insertion into the urethra. Since the catheter has a certain elasticity, after the patient inserts the catheter into the urethra, the catheter can be collapsed by squeezing the catheter, thereby allowing the collapsed catheter to slide out of the side-slip channel 140.

In a third embodiment of the utility model:

as shown in fig. 5, the positioner body 100 in this embodiment further has a light-transmitting region 103, as compared with any of the foregoing embodiments. The positioning hole 120 is formed on the light-transmitting region 103, in other words, the positioning hole 120 is surrounded by the light-transmitting region 103.

Further, although not shown, in a third embodiment of the present utility model, the urethral locator further comprises an LED lamp, a power supply and a switch electrically connected together, the switch being used for controlling the conduction or non-conduction of the LED lamp and the power supply. In other words, when the switch is turned on, the power supply supplies power to the LED lamp and causes current to flow through the LED lamp, thereby causing the LED lamp to be lighted.

Preferably, the LED lamp, the power source and the switch are all provided inside the fixture body 100, and the switch is a push switch so that the switch can be turned on or off when an outer surface of the fixture body 100 corresponding to the switch is pushed.

It is further preferred that the LED lamp is arranged at the light-transmitting area 103 such that the light emitted by the LED lamp is able to illuminate the positioning hole 120 through the light-transmitting area 103, thereby assisting the patient in finding the urethral meatus and assisting the patient in inserting the urinary catheter into the positioning hole 120 and the urethra.

Still further preferably, the power source is a rechargeable battery. Alternatively, the power supply may be provided as a battery fixing structure capable of accommodating the dry battery, as required by those skilled in the art.

In addition, in other embodiments of the present utility model, one skilled in the art can omit the mirror assembly 200 of the urethral positioner of any of the previous embodiments as desired. It will be appreciated by those skilled in the art that if the mirror assembly 200 on the urethral positioner is omitted, the patient is required to determine the location of the positioning aperture 120 by means of another mirror.

Thus far, the technical solution of the present utility model has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present utility model is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present utility model, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present utility model will fall within the protection scope of the present utility model.
