• a conventional catheter 32 has its balloon- equipped anterior end 34 telescoped forwardly through the aperture 22 and the body 12 and the interior of the body 12 includes peripherally spaced inclined fingers 36 which project forwardly. and inwardly from the body 12 and closely embrace the catheter 32 at their inner ends.
• the body 12 also includes an apertured interior partition 38 spaced forward of the end wall 20 and defining a lubrication reservoir ' 40 between the end wall 22 and the partition 38.
• a flexible transparent tubular envelope 42 is provided and includes a forward end sealingly secured about and to the periphery of the plate 24 and a rear end 44 which is transversely sealed closed as at 46.
• the envelope 42 comprises a pair of flat strips superimposed upon each other and secured together along adjacent marginal edges in order to form the envelope. The rear ends of the strips are sealed together and illustrated as at 48 and 50 in Figure 1 and may be pulled apart in order to separate the envelope 42 from about the catheter 32.
• the shield 26 may be separated by engaging the two shield halves disposed on opposite sides of the slots 28 and 30 by the lugs 52 provided thereon and pulling the two shield halves apart.
• the two strips 48 and 50 of the envelope 42 may also be pulled apart inasmuch as each of the strips 48 and 50 is anchored relative to a correspond ⁇ ing shield half.
• the lower peripheral portion of the forward end of one of the shield halves includes a finger-engageable grip 54 projecting forwardly therefrom and including a pair of depending finger- engageable members 56 by which the shield 26 may be more readily handled, see Figure 1.

Then, when the reservoir 62 is compressed between the fingers in order to break the seal 66 and express the lubricant 68 from the reservoir 62 and out through the outlet neck 64 the catheter 32 will not be projected rearwardly from the body 12. The forward end of the catheter 32 is fully lubricated and excess lubricant passes around the fingers and through the partition 38 and into the chamber 40. The lubricant within the chamber 40 serves to lubricate the catheter 32 disposed posteriorly of the shield 26 as the catheter 32 is inserted into the penis 74.
• the clamp 76 engaged with the outlet neck 78 of a pressurized liquid reservoir 80 is released and the liquid 82 within the reservoir 80 is allowed to flow from the reservoir 80 along the catheter in order to inflate the balloon portion 84 thereon.
• the clamp 76 is engaged with the outlet neck 78 through the envelope 42.
• the catheter 32 after the lubricant has been expressed from the reservoir 62, may be readily inserted into the penis 17 in a sanitary manner by guiding the catheter 32, through the envelope 42, forwardly through the body 12. If it is desired, a modified form of -8-
• catheter 33 may be used, see Figure 5, and the pressurized reservoir 80 of the catheter 32 may be replaced by a syringe 63 engageable through a plug 65 after the envelope 42 has been removed.
• a modified form of catheter construction referred to in general by the reference numeral 10" and which is similar in many respects to the catheter 10 and therefore has the components thereof utilized on the catheter 10 referred to by prime reference numerals corresponding to the numerals used in conjunction with those similar components of the catheter construction 10.
• the catheter construction 10' differs from the catheter construction- 10 in that a shield referred to in general by the reference numeral 11 and incorporating rearwardly divergent opposite side panels 13 and 15 as well as rearwardly divergent upper and lower panels 17 an 19 is provided.
