The invention discloses a high imbibition dissoluble drug release external contraceptive membrane, which is prepared by the following raw materials of 0.06-1.2 parts of nonoxynol-9, 2-6 parts of super absorbent resin, 60-90 parts of polyvinyl alcohol, 6-10 parts of polypropylene glycol, 4-8 parts of vegetable oil and the like. The contraceptive membrane made by the use of the composition of materials has elasticity, toughness and crisp property, effectively obstructs the sperms in semen and quickly absorbs semen and kills sperms. After the contraceptive membrane made from the materials is putin vagina, sexual intercourse can start immediately without waiting; and the contraceptive membrane can remain the shape of a crisp septum for up to 4h when not encountering semen, thus avoiding the loss of sperm killing drugs as well as the disappearance of local acrimony. The vegetable oil and vagina mucosa used in the invention have good compatibility and can remove the stimulation effect of the nonoxynol-9 on skin mucosa. The product can absorb the residual liquid and secretions as well as bacteria, viruses and other causative organisms in the secretions after vaginal douche and the treatment of an ozone gynaecology therapeutic instrument, also has killing effect, prolongs sterilization time and improves treating effect.

The invention discloses a special-shaped anti-dropping seminiferous duct sterilization apparatus. The sterilization apparatus is made of a macromolecule polymer material with the thermosensitivity shape memory effect, wherein the shape memory temperature is in the range from 20 to 55 DEG C; and the sterilization apparatus is of a special-shaped structure which can not freely slide along a seminiferous duct after being implanted in a seminiferous duct. The sterilization apparatus is endowed with a shape memory function by fully using the memory property of the macromolecule polymer material with the thermosensitivity shape memory effect in the manufacturing process of the sterilization apparatus; the vitrification conversion temperature of the sterilization apparatus is set at a temperature range appropriate for a human body; before implanted in the human body, the diameter of the sterilization apparatus is maintained to be matched with the inner diameter of the seminiferous duct so that the sterilization apparatus is of a linear type; and after the sterilization apparatus is implanted in the human body, the thermosensitivity memory property of the shape memory polymer material is fully exerted so that the original special-shaped structure is restored, and the seminiferous duct can better adapt to the deformation of the sterilization apparatus and correspondingly changes in shape, thus the sterilization apparatus is stably implanted in the seminiferous duct and blocks the cavity of the seminiferous duct and good contraception effect is achieved.

The invention discloses a male comfortable contraceptive suppository, placed in a urethral canal of a male penis. The male comfortable contraceptive suppository comprises a suppository which is hollow at internal, wherein the side wall of the suppository contacting the urethral canal is provided with air intakes, the outer end of the suppository is connected with a vacuum suction microtube, the outer end of the vacuum suction microtube is connected with a vacuum suction device, and the vacuum suction microtube is further sleeved with a suction microtube fixing device for fixing the vacuum suction microtube on the penis; semen produced when men in ejaculating is blocked in the urethral canal by the suppository, so that the semen is avoided to be contacted with the female cunt so as to contracept effectively; according to the vacuum suction device, the side wall of the urethral canal is absorbed on the peripheral surface of the suppository, so that the suppository is sealed with the urethral canal wall, there is no distending pain and no semen leakage when in use, the contraceptive effect is greatly enhanced, and the sensual pleasure of both parties is improved.

The invention discloses an adjustable intrauterine device. The adjustable intrauterine device comprises an intrauterine device handle, wherein the intrauterine device handle comprises a sector-shaped part, a length regulating part and a connection part, a semicircular plate is arranged at the upper part of the sector part, sector clamping grooves are formed in the two sides of the semicircular plate, an inverted triangle support body is arranged at the upper part of the sector part, the length regulating part is arranged at the lower part of the sector part, and the connection part provided with an external screw thread is arranged at the lower part of the length regulating part. The adjustable intrauterine device disclosed by the invention is simple in structure, low in production and usage cost, different parameters can be regulated according to the actual situations of different individuals, the aims of customization for each individual is realized, application range and adaptation accuracy of the intrauterine device are greatly improved, effect is good, good contraception effect can be achieved, and the harm to a human body also can be reduced; therefore, the adjustable intrauterine device disclosed by the invention has good market potential.

The invention discloses a reducible fallopian contraceptive element, which is composed of 3-5 concentric circular cylinders on one shaft, wherein the upper surface of shaft and upper bottom of first cylinder is on the same surface, the nickel-cemented alloy filament net is set on the external surface of cylinder and external surface of shaft, the cylinder and shaft is made of polyester film or medical polyester fibre.

The invention relates to a Chinese medicinal contraception plaster and its preparing process, wherein the plaster is prepared from raw material cotton root, rhubarb horsetails, arborviate seed, pinellia tuber, asarum herb through the steps of extracting by ethanol backflow, merging the ethanol liquid, filtering, reclaiming ethanol, concentrating into pasty state.

The invention discloses a slow-soluble external contraceptive membrane. The contraceptive membrane is prepared from the raw materials such as 0.05 to 1.5 parts of nonoxinol-9, 0.3 to 2 parts of super carboxymethyl starch sodium, 0.3 to 3 parts of hydroxypropyl methyl cellulose, 0.1 to 0.3 part of polyacrylic resin film agent, 1 to 3 parts of polyethylene glycol, 2 to 10 parts of lubricating agentand the like. The contraceptive membrane prepared by using the material composition has slow solubility and high medicament dissolution, and has effects of absorbing seminal fluid and killing sperms.After the contraceptive membrane prepared from the materials is put into the vagina, sexual intercourse can be performed immediately, and waiting is not needed. The stiff and smooth membrane shape iskept for 3 hours when the contraceptive membrane is not contacted with the seminal fluid, and sperm killing medicaments are slowly released, so that loss of the sperm killing medicaments in short time can be avoided; and the release of the sperm killing medicaments is accelerated when the contraceptive membrane is contacted with the seminal fluid, and the performance ensures high efficiency of the sperm killing medicaments and can improve the contraceptive effect. The membrane material has good compatibility with vaginal mucosa, has irritability resistance, flexibility and comfort, and can eliminate the stimulation effect of the nonoxinol-9 on the skin mucosa.
