INTRODUCTION TO THE INVENTION (j) Field of the Invention The present invention relates to sanitary devices, which are used by men during sexual intercourse to perform the functions of known contraceptive devices, but are more efficient The method further provides other functions and advantages, such as overcoming premature ejaculation and overcoming partial or complete impotence. BACKGROUND OF THE INVENTION Contraceptive devices used by men are visible on the one hand so as to prevent pregnancy and on the other hand to prevent diseases transmitted through sexual intercourse. This latter function is of particular importance because of the emergence of AIDS. However, known devices cannot always perform the set functions in a complete and efficient manner. On the one hand, the device suffers damage; on the other hand, the device is difficult to use with incomplete erections and without erections. Furthermore, the device cannot perform effective functions during early ejaculation. The present invention overcomes these disadvantages and provides a device used by men during sexual intercourse, which in various embodiments can prevent pregnancy, overcome the effects of premature ejaculation, and overcome problems due to impotence or inadequate sexual intercourse. Another object of the present invention is to provide such a device including a number of embodiments', each of which is used to obtain a special effect. Printed by the Central Panasonic Bureau Shellfish Consumer Cooperative ¾ • II (Read the precautions on the back before filling out this page} A further object of the present invention is to provide such a device with the same structure as the previous embodiment, so the manufacture can Standardization. Other objects and advantages of the present invention will appear in the description. SUMMARY OF THE INVENTION The sanitary device of the present invention is characterized in that it includes a substantially tubular body that can be easily deformed and has the ability to direct the body to air pressure so that the body is substantially expanded. Device and device for exhausting gas-the main body 'When this paper size is applicable to China National Standards (CNS) No. 8 (4) Taiwan () Printing by the Smoke Drop Department Central Standards Bureau Shellfisher Consumer Cooperative 518217 V. Description of the invention ( ,) Is guided to this expanded state and is not deformed by contact with any other body, and has a middle, substantially cylindrical outer surface and an axial channel surrounded by a semi-spiral end portion. The term "essentially tubular body" is used Here, because the body is defined by a) the outer surface of the cylinder, and b) the inner surface, it is the surface of the axial channel and the solid Also on the cylindrical outer surface coaxial. As is known to all, the term "annular circle" describes a solid or surface created by a circle rotating around an axis that does not intersect. The term "semi-spiral" means the body or surface of a half-circle that has been cut along a plane of symmetry. This essentially tubular body, hereinafter also referred to as a "sheath", is usually easily deformed in use for simplicity's sake, and will be described in detail hereinafter, particularly by contacting other bodies with the outside and, or inside, and more particularly the The tubular, axial space can be partially released, the semi-helical end portion can be deformed to approximate the frusto-conical portion or otherwise, and the deformation between the ends can be wrinkled or deformed, which deformation causes the protection The sleeve deviates from the shape defined by the previous noun. The above terms define the ideal shape of the body in the expanded state. Because of this structure, the sheath according to the present invention can be rolled along the catheter or delivery tube as the spiral end portion rolls over the catheter or delivery tube and also slides into the inner surface to a greater or lesser extent. In this movement, when all the shapes of the device remain essentially unchanged, the clear part of any sheath will continuously occupy different positions, that is, the segments that make up the semi-spiral end part can become the middle of a part, which is essentially cylindrical Part and vice versa. In the embodiment of the present invention, the axial passage is sealed at the proximal end, or at a short distance from the proximal end. With the term "proximal", it is not further explained that it means that the Chinese National Standards (CNS) Λ4 is now available (210X297) at the 4 paper scale ~ (The first read the notes on the back and fill out this Tio- Binding and ordering 518217 Printed by the Central Bureau of Labor Standards and Consumer Cooperatives in China Ⅴ. Description of the Invention (3) The sexual behavior is approaching the end of the male user. After that, the channel seal will approach as the cover rolls over. The other end of the sheath. With the term "end", there is no further explanation to mean the end away from the male user at the beginning of sexual activity. The terms "real near end" and "real end" will respectively indicate the orgasm of sexual activity It is closer and farther away from the end of the male user. In another form of the invention, the sheath is additionally complemented by a removable, rigid, or at least sturdy sleeve that is placed around the base of the male sexual organ to assist The guiding organ enters the sheath when the sheath is in the folded state and is removed after being guided. The sheath itself is as previously defined and the deformation has two embodiments, as long as the axial channel can be opened Or close. The sanitary device of the present invention is used to guide the penis into the proximal end of the axial channel of the device, and allows gas, usually air, to enter the sheath under normal pressure, thus expanding the sheath. After sexual orgasm The gas can be expelled, at least partially helping to expel it. The sheath of the invention can be prepared by providing a thin, flexible plastic tube, folding the tube so that one segment is placed in another segment It can also be referred to as "internal segmentation" and side by side and combining the two ends of the tube. In the embodiment of the present invention, the tube has a restricted cross section at the point where this type of tube will be positioned completely sheathed away from the gas inlet The present invention also provides a method for overcoming impotence or insufficiency, comprising: a- providing a sheath of an essentially tubular body, the sheath being easily deformable and having a means for guiding to air pressure The device that becomes a substantially expanded state and is used to discharge the gas-sheathing device, when it becomes a substantially expanded state and is not deformed by contacting any other body, has an intermediate, substantial (read first read Read the notes on the back and fill out this page) • Install · ， 1Τ #

Description of the invention (() The first of the invention The device of the embodiment is shown in Fig. 1 in the dilated shape, before use. The sheath is usually labeled 10, and can be observed | only part of the outer surface of the cylinder and it has a distal end and a proximal end, respectively; ^ Stomach ^ Semi-spiral surface. The device has an axial channel 14, which is opened at ~ 7 (Figure 1A) and in another variation closed by a seal 22 (B) at the proximal end. A gas channel 16 is attached to the sheath 17 near the distal end. The gas used is preferably air. At the input port, the tube 16 is attached to the gas source, which is labeled as 18 briefly. It can be conveniently a manual pump. It can be a single & container. If the ball has an input valve 19, it has an output.阀 20。 Valve 20. When the reference is to be reached, hereafter referred to as "pump", it should be understood that this is not a limitation ^ and any convenient air pressure source should be used, ie a small container with air pressure, if it has an output valve. The other valve 21 is installed near the inlet 17 of the tube 16. The input tube 17 is placed in the operation position of the device, and will be inserted later. The sheath 10 is guided to the expanded state by initially placing an input tube 16 connected to a pressure source 18. If the source 18 is a manual pump, the valves 19 and 20 are automatically opened and closed during operation; in other forms of pressure source, they should be operated by the user of the device. When a sufficient amount of air is introduced into the sheath, the sheath becomes the expanded state of FIG. 1. Figure 2 shows the device when the user starts to use it. The element symbol 25 is designated as a male sexual organ, the tip of which is introduced into the sheath forming the socket 15. Subsequently, as shown in Fig. 3, the organ 25 is advanced into the device 10 and at the same time, the device is guided to the vagina and the surface is designated 26. This caused the device to roll so that the input port 17 of the catheter 16 was originally closer to the end of the device and moved to the real end.

In Figure 4, the device 10 with male sex organ 25 is partially retracted and its shape is between that of Figures 2 and 3. To fully release the male sex organ from the sheath of the present invention, valve 21 It is open and the gas is discharged from the inside of the sheath, and this is folded and can be easily extracted. When all the elements shown in the diagram have a circular cross-sectional area, (only the pressure source 18 does not have such a cross-section) there is no cross-sectional diagram. The device needs to be shown. In the embodiment of FIGS. 5 to 8 which is used to overcome complete impotence, the sheath 30 is set the same as the above device and is set to open the inner channel as shown in FIG. 1A or have a sealed inner channel as shown in FIG. 1A. 1B. The sheath is provided as shown in the previous embodiment, and has an input pipe 31 and a pressure source 32 provided with valves 33, 34, and the input pipe 31 is provided with a valve 35. As seen in FIG. 8, during the descending state and sexual activity, The sheath 30 has an inner channel 36, as opposed to the channel 14 of the embodiment of Figs. 1 to 4. The sheath 30 is made of at least a rigid sleeve 40, made of an adhesive tape, which is only long enough to accommodate the sheath 30 in The folded state is shown in Figs. 5 and 6. In Fig. 5, the air pressure source or pump 32 series is placed in the sleeve 40, for convenience of packaging, but this part is not functionally related. As shown in Fig. 6 With the sheath 30 supported externally in a folded and bent state, the sleeve 40 is slid into the male organ 38, which is not sufficiently erected. Subsequently, the strap of the sleeve 40 is slid out and the sheath 30 is still in the male organ 38 Close to the base, as shown in Figure 7. At this point, the sheath 30 is applied to the Chinese National Standards (CNS) eight-four gauge (210χϋ ラ Γ — ~ · '(ti71 by reading the back and the Note 4 fill out this S) equipment, 1T # by the Central Standards Bureau of the Ministry of Liberal Consumer Cooperatives System 518217 A7 1Π _------ — ______________________ ______ One One_ One Five. Description of the Invention (1) Source or pump 18 expands, and the whole has a configuration similar to that in Figure 3, so that sexual behavior can be Implemented. Figures 9 to 11 show how the device of Figures 5 to 8 can be manufactured. However, the manufacturing process can usually be used to make the device of Figure 1. The tube designated 40 is folded, as seen in Figure 9. The tube Is provided with a reduced section 45. As shown in Fig. 10, the end portion 43 of the section 41 is then folded over the end portion 44 of the section 42, and finally as seen in Fig. 11, the two ends are connected, i.e. by Welding or by an adhesive or by any convenient method. The input pipe 46 is provided with an output valve 47 and is connected to the air pressure source 48 and has an input valve 49 and an input valve 50. The pipe is connected to the outer portion of the sheath at 51, close to the end, and far enough away from the portion 45. It should be noted that in all embodiments, the surface of the sheath need not be smooth and can be provided with irregularities, protrusions, waves, etc. to control the degree of friction during use. These details can be easily set by a skilled person and need not be displayed. The device rolls into a catheter of any diameter without substantial resistance. Figures 12 and 13 show another embodiment of the device which is fitted with a cover (element symbol 60) covering the head of the penis during different stages of sexual activity. The component symbols 16, 18, 25, and 26 have the same meanings as described above. In various embodiments, the device achieves effects not possible with existing contraceptive devices. With existing contraceptives, it is completely effective in preventing infections and preventing pregnancy when the axial channel such as 14 is sealed. However, it always helps to guide the male sex organ to the female sex organ. In fact, during the guiding process, the sheath can be expanded to reduce the diameter slightly and the diameter can be increased. By 9 paper sizes, the Chinese National Standard (CNS) Λ4 Regulation (210x? 97 > >); ^) 丨 ^ Binding (诮 Read the precautions before filling in this page) 518217 V. Description of the invention (Y) Increase the air pressure in the sheath. When the axial channel 14 is opened, it enters the seat 15. When the axial channel 14 is opened into the socket 15, pregnancy is not avoided but still has a degree of resistance to the disease because the axial channel is extremely narrow and the ends will be filled with semen. In the case of early ejaculation, the sheath essentially maintains its shape and size and allows filling to complete sexual activity. Obviously all the embodiments are different from each other, with regard to the basic structure so that the manufacturing stage of the device is essentially the same and the cost of the device can be reduced. A suitable plastic tube for manufacturing the sheath may have a thickness from 5 to 100 and include a suitable plastic material, such as polyurethane or natural or synthetic rubber. When the embodiment of the present invention has been described by way of illustration, it is obvious that the present invention can be implemented with many changes, improvements, and applications without departing from or exceeding the scope of the appended patent application.
