Embodiments of the present invention

[0096] it is to more fully understand the present invention, with reference to accompanying drawing, technical solution of the present invention is illustrated by embodiment, illustrate inch, same parts and described in each embodiment in embodiment before being formed in, afterwards by the default narration in embodiment, not the missing of technical characteristic, illustrates hereby.

[0097] embodiment one, as shown in Figure 1, the preventing humor safe cross set, the overcoat 1 closed provided with front end is glans penis accommodation space at the front end closing of overcoat 1, using inch glans penis overhead in glans penis accommodation space；Flexible inner sleeve 2 is provided with overcoat 1, inner sleeve 2 is roughly the same with the direction of overcoat 1, the cross section of inner sleeve 2 is in a ring, the equal Jian in the front-end and back-end of inner sleeve 2 is put, the point diameter of inner sleeve 2 is less than its rear end diameter, by front end, diameter is gradually increased the present embodiment inner sleeve 2 backward, and overall is in cone cylinder shape；Inner sleeve 2 is located at glans penis rear portion, the at least point diameter of inner sleeve 2 is less than the diameter of overcoat 1, the front end of inner sleeve 2 is by its own elastic force lock ring on the penis at glans penis rear portion, and lock ring position does not have gap between the front end of inner sleeve 2 and penis, and back segment gradually loosens the lock ring degree to penis；The rear end of inner sleeve 2 is connected with the inwall of overcoat 1, and the body fluid receiving space 3 that a front portion Jian is put is formed between inner sleeve 2 and overcoat 1, and body fluid receiving space 3 refers to the space for accommodating the body fluid that rear portion is flowed to along the inwall of overcoat 1.Inner sleeve 2 can be integrally formed with overcoat, can also split shaping be bonded combination again.

[0098] sheath structure packaging inch, is begun to roll, to glans penis accommodation space, inner sleeve 2 is flexible, as crimping action is begun by rear portion Jian, is partly or entirely involved in wherein by the Jian of 1 tail end crimping of overcoat 6, places into packaging bag encapsulation.When the part of inner sleeve 2 is involved in inch, do not roll the front end for still having inner sleeve 2, use inch, glans penis accommodation space is excluded glans penis is wrapped after air, body exhibition Jian is crossed after glans penis, slightly lifts body, because overcoat and glans penis are respectively provided with elasticity, even if being easy to the front end of inner sleeve 2 falls into coronary sulcus, loosen body and continue to open up Jian to radix penis part, you can use；This coiling method is relatively specific for the earlier body in the front end of inner sleeve 2.

[0099] when inch rearward is compared in the front end of inner sleeve 2, can all it be involved in, can attach sets drawstring 41 together to roll on the outside of overcoat, the front end of drawstring 41 forms one and pulls and supports end 42, overcoat can be all involved in by pulling and supporting end 42, as shown in figure 25, body is in drawstring not yet roll-up state in figure, and end 42 is pulled and supported after rolling and will be involved in body；Overcoat can not also be all involved in by pulling and supporting end 42, as shown in figure 26, and body is in drawstring roll-up state in figure, pulled and supported end 42 and be not involved in body；Pull and support end 42 to be involved in or non-involvement body, must meet and pull and support end 42 before inner sleeve 2, drawstring rear end is located at after the front end of inner sleeve 2；It can also be more than two that drawstring, which can be one, be one Inch can be strip, or tubular, and drawstring is more than two inch, and rear end can link together, and pull and support end 42 or multiple；Use inch, glans penis is wrapped after glans penis accommodation space is excluded into air, exhibition Jian crimping portions pull and support end 42 to exposing, and then pull back and pull and support end 42, and the body for driving curling by drawstring opens up Jian, the front end of inner sleeve 2 is set to plough under on the inside of overcoat, lock ring is on penis, and drawstring is opened up after Jian completely, removes drawstring, continue to open up Jian bodies to radix penis part, you can use.

[0100] when inch rearward is compared in the front end of inner sleeve 2, can all it be involved in, lacing wire 44 can be connected between the front end of inner sleeve 2 and overcoat 1, as shown in figure 31, use inch, glans penis is wrapped after glans penis accommodation space is excluded into air, open up Jian curling bodies, the upset under the drive of lacing wire 44 of the front end of inner sleeve 2 opens up Jian to penis, Jian bodies are opened up to radix penis part, it can be used, window 45 of the body fluid between lacing wire flows to body fluid receiving space 3 backward, this structure is simple compared with drawstring formula.

[0101] when inch rearward is compared in the front end of inner sleeve 2, the stacking of axial direction can also be set on the anterior overcoat body of overcoat 1 and the junction of inner sleeve 2, such as Figure 32, shown in 33, at Figure 32 stackings 46 are stacked for turnover type, at Figure 33 stackings 47 are stacked for wave, as long as concrete mode can make the axial extensible Jian of overcoat shortening, as can be also stacked using nature fold, spiraling manner, make the front end of inner sleeve 2 close to the glans penis accommodation space of the front end of overcoat 1, both can fit together in the case that shape is coincide, with overcoat 1 at stacking, inner sleeve 2 is rolled, packaging is put into after rolling.Use inch, glans penis is wrapped after glans penis accommodation space is excluded into air, body exhibition Jian, which is crossed after stacked position, stops exhibition Jian, lifting body is not opened up and Jian is axially opened up at Jian turned up portion, the stacking of overcoat 1 backward, and the exhibition Jian parts of inner sleeve 2 are moved by after drawing entirety, because the front end of inner sleeve 2 and glans penis are respectively provided with elasticity, the coronary sulcus for making the front end of inner sleeve 2 fall into glans penis rear portion is easy for, exhibition Jian bodies turned up portion is then proceeded to radix penis part, you can use；The method is succinct compared with drawstring mode.In order to judge stacked position well, it can also be indicated on inner sleeve further on the outer set at stacking or at correspondence stacking with the pattern of other colors.

[0102] inch is used, the front end lock ring of inner sleeve 2 is on the penis at glans penis rear portion, the body fluid and seminal fluid of wearer's secretion are during pulling and pushing, caudad flowed along the inner side of overcoat 1, liquid flows to the front end inch of inner sleeve 2, because the front end lock ring of inner sleeve 2 is on penis, the lock ring position very close to each other is in high-impedance state to liquid, and its rear is in low resistive state, under the guiding of inner sleeve and outer inner room low impedance path, liquid flow posteriorly closing space, it is stored in body fluid receiving space 3, it will not be leaked by overcoat tail end, prevent wearer's body fluid and seminal fluid from contacting other side, the effect of contraception and anti-disease propagation can effectively be improved. [0103] same to inch, this structure is effectively improved the receiving space of seminal fluid and body fluid, is not limited in the front end of overcoat 1, volume space is around first half spatial distribution in overcoat, with stronger dispersiveness, effectively prevent liquid accumulation in front portion extruding rupture.

[0104] also have, the position that penis is wrapped up by the overcoat 1 of inner sleeve 2, the rear portion of inner sleeve 2 will not touch the body fluid of wearer, be not easily susceptible to the lubrication of body fluid using inch and come off, it is clean comfortable after taking off.

[0105] because the front end of inner sleeve 2 is strapped on penis by elastic force, by the binding force, larger frictional resistance is formed between the front end of inner sleeve 2 and penis, influenceed by the frictional resistance, the tail end of overcoat 1 is pulled to take off inch, inner sleeve 2 is driven to turn up, inner sleeve 2 is last from Jian penises under frictional resistance delay effect, inner sleeve 2 turns over the body fluid of the non-sticky both sides in position, other side's body fluid so on the outer surface of overcoat 1 is just not easy to be stained with the glans penis position of wearer, can further prevent humoral cross；And existing condom, not only wearer's body fluid easily have in tail end with other side's body fluid and intersect, condom tail end contamination other side's body fluid after, also can be infected with glans penis position easily taking off inch, this technology can be efficiently reduced or avoided in these problems.

[0106] the elastic binding force of the inner front end of sleeve pipe 2, in wearer inch is extracted out of other side body, starting stage is not dominated by hand, also it is unlikely to overall to come off in other side's body, but the process that inner sleeve 2 gradually turns up, the front end of inner sleeve 2 moves on to coronary sulcus, front end edge is embedded in coronary sulcus, under stopping at the edge that glans penis is protruded, the obvious increasing of delay effect to the front end of inner sleeve 2 has ensured the finally disengaging of inner sleeve 2.

[0107] sexual life inch, feel to mostly come from glans penis with impulsion, inner sleeve 2 can't cover glans penis, therefore it does not interfere with the stimulation that friction is brought to glans penis, keep glans penis to stimulate the pleasant sensation brought, but inner sleeve 2 wraps secondary sensation and the part penis at the source glans penis rear portion of impulsion, overcoat 1 constitutes double-decker with it, and can isolate decrease friction stimulates, and can suppress penis pleasant sensation, reach that some prolong inch effect, reached a climax between the more inch of other side.

[0108] on inner sleeve tube shape, inner sleeve 2 is to be gradually increased by front end to rear end diameter change in example, overall is in cone cylinder shape, implement inch except this linear change, the other shapes of nonlinear change can also be used, such as curvilinear motion, stepped change, and it is not limited to become always before big and inner sleeve diametrically minimum, inner sleeve leading portion as shown in Figure 2 is in outer gibbosity, inner sleeve leading portion shown in Fig. 3 is in inner concavity, inner sleeve leading portion shown in Fig. 4 is stepped, inner sleeve leading portion shown in Fig. 5 is in wavy, the non-minimum diameter of inner sleeve forward position shown in Fig. 6, inner sleeve point diameter need to only be met less than its rear end diameter, inner sleeve front end size is suitable to the penis at lock ring glans penis rear portion, inner sleeve rear end size is suitable to be connected with overcoat, it is not limited thereto several forms；Inner sleeve is axially longer Inch can be divided axially into two parts, and back segment is cylinder 201, and leading portion is reducing cylinder 202, as shown in Fig. 2 to 5, so can both keep forward end seal, can reduce pressure of the back segment to penis again, also with larger body fluid receiving space 3;Back and forth change can also be such that reducing cylinder 202 is preferably positioned on penis to diameter, hoop more firmly, sealing is more preferable.
