      The invention is related to providing a medicine injection device, and particularly, to providing a portable medicament jet-spraying and injection apparatus including a loading portion subject to receiving a predetermined gel typed semisolid or liquidized medicament and for douching the special regions of a human body such as vagina, anal region, etc. and injecting it thereinto in a jet-spraying manner, if necessary.  
      Prior Arts  
      A modern is being changed into a society of complex and busy everyday life and experiences to be continuingly kept. In order to be easily adapted to the modern life, there has been developed various tools or devices to consult the convenience of everyday life. Nevertheless, it is noted that it lacks of the development of a conveniently sized tool or device related to the hygiene and/or for the contraception of women or the insertion into a special region of a human body.  
      In other words, it is important to be careful of health elements such as the hygiene of the genital organ and vagina of women and the insertion of the contraceptive pill thereinto, the cleanliness maintaining of anal region, etc. in order to prevent diseases. But, a series of hygiene works in inserting the contraceptive pill into the human body or administrating an enema to a person have been done using hands, which is not easy and troublesome.  
      As it is already well known, the genital organ, vagina and anal region of human body are very sensitive and weak portions, so that their treatment or processing requires a larger carefulness. Particularly, it must be given a lot of attention to the insertion of lubricant or contraceptive pill for the sexual intercourse and medicament liquid for the treatment and prevention of the sexual disease into the genital organ or vagina and to the rectal injection of the enema.  
      Until now, there has been not known any device or tool that makes it convenient to douche a special region of human body such as genital organ, anal region, etc. and/or to inject a predetermined medicament thereinto. That is because the device has various limitations to ifs use including the portability that is easy to carry.  
      A typical technology is disclosed in Japanese Laid-Open Patent Publication No. 2001-187151, which is related to a lubricant injection device that is easy to use. The lubricant injection device comprises a plastic cylinder including an outlet port of lubricant formed at its front end and a push rod fitted into the cylinder with lubricant being charged in the front portion. The lubricant injection device enables lubricant to be applied to sexual organ or vagina in a shot time. It also removes impediments caused by a mechanical contact with corresponding sensitive regions and reduces metal burden on its safe use. And also, the lubricant injection device is easy to carry and convenient.  
      But, the lubricant injection device has no any countermeasure to the leakage of lubricant charged in the front portion of the cylinder, which means that it needs a lot of carefulness upon its usage. Furthermore, the lubricant injection device is disclosed as a syringe that can be inserted into a special region of human body, but it has a disadvantage in that due to its structural simplicity its use may be limited.  
      In light of these points, it is preferable if a medicine injection apparatus is easy to carry, safe to use and convenient to use a predetermined medical liquid or medicine in a quick time anywhere in order to douche a special region of human body and/or inject thereinto.  
      An object of the invention is to provide a portable medicament jet spraying and injection apparatus including a loader or container with a predetermined medicament being charged therein to douche a special region of human body and/or inject the medicament thereinto in a jet-spraying manner.  
      Another object of the invention is to provide a portable medicament jet spraying and injection apparatus including a loading portion or container of a gel typed capsule structure with a semisolid or liquidized medicament being charged therein to douche a special region of human body and/or inject the medicament thereinto in a jet-spraying manner.  
      Another object of the invention is to provide a portable medicament jet spraying and injection apparatus including a cap portion formed to secure a loading portion and prevent the leakage of liquidized medicament charged therein and a push rod separated therefrom to douche a special region of human body and/or inject the medicament thereinto in a jet-spraying manner.

     DETAILED DESCRIPTION OF THE INVENTION  
      According to one embodiment of the invention, as shown in  FIG. 1 , a portable medicament jet spraying and injection apparatus  10  comprises a cylinder  1  including an insertion  2  expanded in an oval or circular shape at its front portion, a dept portion extended in a straight line from the lower of the insertion  2  and a first expanding portion  8  expanded outside toward its lower end at a funnel shape. The cylinder  1  has a hollow formed in the same diameter through its all length portion, in which a loading portion is formed adjacent a front end to receive a gel typed gelatin capsule  4 .  
      A piston portion  5  is positioned adjacent the loading portion as described below in detail. The piston portion  5  includes a plurality of grooves  6  formed surround the outer circumference thereof. Some or any one of the grooves  6  is coupled with a fixing portion formed in the cylinder  1  to determine the fixing position of the piston portion. The other grooves  6  comprise a seal member such as a rubber-inserted thereinto to seal a lower opening of the loading portion. A push rod  7  is separated from the piston portion  5  and includes a second expanding portion  9  formed at a lower end to couple with the first expanding portion  8 .  
      Referring to  FIGS. 2, 3  and  4  for the purpose of explaining the invention more in detail,  FIG. 2  is a whole cross-sectional view;  FIG. 3  is a partly enlarged cross-sectional view and  FIG. 4  is a cross-sectional view illustrating the operating of a portable medicament jet spraying and injection apparatus.  
      A cylinder  1  includes an insertion  2  expanded in a circular or a streamline form of an oval somewhat over a length portion  3 , so that it is easy to be inserted into a special region of human body. A jet-spraying nozzle  11  is formed to have a certain depth portion that is extended downward from the front. A cutter  12  is constituted as a blade integrated with the jet-spraying nozzle  11 . A hollow portion  13  is formed to surround the circumference of the jet-spraying nozzle  11  adjacent thereto, so that it facilitates the insertion of medicine liquid into a loading portion  15  as described in detail below.  
      The loading portion  11  is formed as a hollow space for receiving a gelatin capsule  4  of a semisolid type or medicament of a medicine liquid type. For example, the gel typed capsule  4  having a predetermined medicament is previously charged into the loading portion  15  in the cylinder  1  through the inner hollow space of the length portion  3  from the first expanding portion  8 . The loading portion  15  has a volume to be determined by the piston portion  5 .  
      The piston portion  5  is a disk plate of a predetermined thickness comprising a plurality of grooves  6 . For example, the grooves  6  includes upper groove into which a sealing member  16  such as elastic rubber is inserted and lower groove into which an annular projector  17  formed in part or all over around the inner circumference of the cylinder  1  is fitted.  
      The push rod  7  is fitted into the hollow space of the length portion  3  to be positioned at a predetermined position therein with being separated from the piston portion  5 . In other words, from around the inner circumference of the cylinder  1 , a stopper  9  is projected, the upper of which is formed as a rectangular step portion to its inner wall surface and the lower of which is formed as a slanting portion sloped from the step portion. The push rod  7  includes a rib  14  extended all over from the outer circumference thereof to engage with the step portion of the stopper  19 . As the push rod  7  is inserted into the length portion  3 , the rib  14  rides on and then passes over the stopper  19  to be supported at a predetermined position.  
      As shown in  FIGS. 3 and 4 , the portable medicament jet-spraying and injection apparatus  10  enables the gelatin capsule  4  to be positioned in the loading portion  15  in which the medicament is charged. As the push rod  7  is pushed inward contacting with the piston portion  5 . The cutter  12  breaks out the upper portion of the gelatin capsule  4 , so that the medicament therein is injected into or distributed over the special region of human body through the jet-spraying nozzle  11 . Herein, it is noted that the medicament may be douching material or lubricant.  
      On the other hand, another configuration of a piston portion  5  and a push rod  7  is shown in  FIG. 5 . The piston portion  5  includes a groove  5 ′ formed at the lower center thereof, and the push rod  7  includes a projection  7 ′ projected upward from the upper surface thereof to be fitted into the groove  5 ′. The projection  7 ′ serves as a handler to position the piston portion  5  at a certain position with being coupled with the groove  5 ′, so that the medicament of liquid or semisolid type is charged into the loading portion  15 . After the medicament is completely charged, the push rod  7  is forcedly distorted from the piston portion  5  to be separated from each other. Of course, the groove  5 ′ and the projection  7 ′ each includes a threaded portion formed on the inner and outer portions thereof to be coupled to each other.  
      Another embodiment of the invention is shown in  FIGS. 6 and 7 . According to this embodiment, a portable medicament jet-spraying and injection apparatus  10  is the same as the first embodiment except a configuration that a cutter  12  is not provided on a jet-spraying nozzle  11 . Therefore, further detailed explanation may be deleted to avoid the overlap. Only, it is noted that a piston portion  5  having a position previously fixed to have a predetermined volume defines a loading portion  15 . The charging of medicament into the loading portion  15  is to form a certain space using the piston portion  5  and the push rod  7 , properly, in order to insert an amount of medicament with the jet-spraying nozzle  11  being not sealed at the upper end. Otherwise, an amount of medicament may be charged into the loading portion  15  using a needle passed through a hollow portion  13 .  
      As described above, the loading portion  15  is constituted as an independent chamber by the piston portion  5  with being completely sealed. As the pushing rod  7  is pushed against the piston portion  5 , the medicament charged into the loading portion  15  is injected into or distributed over a special region of human body through the jet-spraying nozzle  11  for establishing a predetermined purpose. The circular or oval insertion  2  is safe for human body. Also, the cylinder  1  having the medicament is safe and easy to carry.  
      Another embodiment of the invention is shown in  FIGS. 8, 9 ,  10  and  11 , in which the  FIG. 8  is a view of a quadrilateral cap portion,  FIG. 9  is a view of a semicircular cap portion,  FIG. 10  is a view of a triangular cap portion and  FIG. 10  is a view of a trapezoidal cap portion.  
      According to this embodiment, a potable medicament jet-spraying and injection apparatus  10  comprises a cylinder  1  and a cap portion  20 , in which the cylinder  1  includes a length portion  3  and its inner structure such as a stopper and a piston portion  5  same as the first embodiment. Therefore, the detailed description to the same elements or parts referenced by same numbers may be deleted.  
      Part unlike the first embodiment is that the cylinder  1  is coupled with a cap portion  20  instead of an insertion  2 . The cap portion  20  includes a male engagement  18  forming a plurality of threads around the upper circumference thereof.  
      The cap portion  20  includes a jet-spraying nozzle  21  extended downward in a predetermined depth from the upper end thereof and a loading portion  22  having a hollow space for receiving medicament of a semisolid or liquid type. Also, the cap portion  20  includes a membrane member  23  for sealing the lower opening thereof and a female engagement  24  extended downward from the lower portion thereof, on the inner circumference of which a threaded portion is formed to couple with the male engagement  18 . Therefore, the cap portion  20  has medicament in the loading portion  15  with the upper end of the jet-spraying nozzle  11  being sealed by an adhesive tape, etc and the lower opening being closed by the membrane member  23 .  
      Next, the cylinder  1  is assembled so that the piston portion  5  is positioned adjacent the upper portion thereof by coupling an annular projector  17  formed on the inner portion of the cylinder  1  with the groove  6  thereof, and the push rod  7  is positioned in the hollow space thereof in a manner to engage a stopper  19  formed on the inner portion of the cylinder  1  with a rib  14  of the push rod  7 .  
      Such like cap portion  20  can be constructed as various shapes to charge medicaments including douching agents or lubricants thereinto for the purpose of many uses. Therefore, as the pushing rod  7  is pushed against the piston portion  5  to break the membrane member  23 , these cap portions  20  fixed on the upper male engagement  24  injects the medicament charged in the loading portion  22  into or distributes over a special region of human body through the jet-spraying nozzle  21  like the above embodiments.  
      As described above, the invention enables the effective charging of medicament of a semisolid or liquid type into an independent hollow space thereof and the rapid injection and distribution of medicaments thanks to their use convenience. Furthermore, the invention enables a special region of human body such as genital organ, vagina, anal region, etc. to be douched for the cleaning purpose or to be injected into a special region of human body in a jet-spraying manner for the purpose of the contraception or the protection of venereal disease, effectively.
