Abstract
Description
Title of the invention: Device to aid injection into the penis.
[0001] The present invention relates to the medical field and specifically concerns a medical device to assist with injection into the penis. The typical example is the injection of vasodilator solution for the treatment of erectile dysfunction (ED). Currently, syringes adapted for this treatment are available on the medical market and are used manually by patients who lack any assistance in positioning the injection, especially if they are overweight and have limited vision. This device is designed to assist in the correct positioning of the syringe and also to reduce the stress of self-injection in a sensitive area.
[0002] The first injection must always be administered by a doctor in their office to determine the specific dose appropriate for the patient and to teach the injection technique, which can then be performed independently. It should be noted that the dose of product to be injected varies considerably from person to person and must be gradually adjusted by a specialist physician. The product is injected using a very fine needle into a relatively insensitive area of the penis, on the side, at a suitable location to avoid contact with the urethra or neurovascular structures.
[0003] The invention relates to a device for assisting injection into the penis which consists of five parts: A box, a lid, a spacer, a slide and a thickness shim.
[0004] A parallelepiped box (A) comprising
[0005] 1) a longitudinal hollow half-cylinder (2) along its entire length,
[0006] 2) two housings (3) on the side of the hollow half-cylinder (2)
[0007] 3) two coaxial lateral cylindrical holes (4), perpendicular to the axis of the hollow half-cylinder (2), not passing through the two housings (3), ending in the hollow half-cylinder (2).
[0008] A lid (B) for the box comprising:
[0009] 1) a rectangle fitting to the top face of the box (B)
[0010] 2) a thin mirror glued under the lid over its entire dimension.
[0011] 3) two hinges allowing the lid to be opened longitudinally, the axis of rotation being perpendicular to the axis of the hollow half-cylinder (2), at the rear of the device.
[0012] A spacer (C) dimensioned to fit snugly but also to be freely inserted into the cylindrical holes (4), pierced along its length with a cylinder whose inner diameter allows it to receive commercially available medical syringes intended for penile injections. The inner end of the spacer is
[0013] equipped with a shoulder in the bore intended to stop the syringe which will be used, and thus to define its correct positioning.
[0014] A slide (D) comprising;
[0015] 1) A cylindrical half-tube (8) dimensioned so as to be able to slide in the hollow half-cylinder (2) This half-tube is hollowed laterally at the place (7) where the needle of the syringe (F) can pass.
[0016] 2) A rectangular front face perpendicular to the axis of the cylindrical half-tube (8), open identically to the inner cylinder of the latter.
[0017] Spacers (E). A spacer is a cylindrical half-tube that fits inside the slide (D) to reduce its diameter. Several spacers of varying thicknesses will be available. These spacers are hollowed out laterally at the point (8) where the syringe needle (F) can pass.
[0018] According to the invention, the medical device is intended to be fixedly placed on a flat surface (table, desk, bathroom cabinet, etc.) at hip height. It has the shape of a box that opens, characterized in that it comprises several parts ([Fig. 3]):
[0019] A rectangular lid (B) with a mirror (1) on its inner part, the orientation of which changes depending on the degree to which the lid is opened. Its function is to allow the patient to always see the action in progress, even in the case of overweight.
[0020] A rigid container (A) containing a central longitudinal hollow half-cylinder (2) for the penis and, laterally, two perpendicular transverse cylinders (4), into one of which the pre-prepared injection syringe is inserted via a spacer (C). The patient can thus choose to inject from the right or left side. The common axis of these two cylinders is perpendicular to the axis of the longitudinal hollow half-cylinder. Two lateral reservoirs (4) allow for discreet storage of a syringe. The device remains fixed by means of four adhesive pads (5) located on the four corners of the underside of the container.
[0021] According to one embodiment, the device is characterized in that ([Fig. 2]), a sliding semi-cylinder-tube (D) is inserted into the hollow half-cylinder (2) of the box (A), the purpose of which is to adapt the device to the length of the user's penis. This semi-cylinder-tube terminates, on the user's side, in a rectangular plate (9) which is placed against the user's scrotum, allowing the device to be adjusted to the appropriate size. Graduations at the bottom of the hollow half-cylinder allow the sliding semi-cylinder-tube to always be repositioned in the correct position.
[0022] Thickness shims (E), also in the shape of a half-cylinder-tube, can be easily fixed in the sliding half-cylinder-tube, in order to adapt the device to the
[0023] width of the user's penis. Laterally, two transverse parallelepiped-shaped housings (3) into which the previously prepared injection syringes can be slid if necessary.
[0024] Two lateral transverse cylindrical holes allow the user to choose the side from which the syringes (4) are inserted. To do this, the patient inserts a spacer (C) into one of the two holes to allow the syringe to be inserted and removed without jamming. This spacer also serves another purpose: to allow the device to be adapted to syringes of different diameters. While currently there are two suppliers of pre-filled syringes for penile injections (ED treatment), both with the same diameter of 14 mm, new products and / or new syringe sizes can be expected in the future.
[0025] Figure 1 schematically represents the penis and a syringe positioned in the device. Note that the syringe (F) is not part of the device and is shown in the drawing for illustrative purposes only.
