The specific embodiment
As shown in Figure 1, be the structural representation of this utility model vagina and cervix uteri administration injector first embodiment, provided a kind of vagina and cervix uteri administration injector 10 among the figure, it comprises urceolus 50, protecting cover 20, spring spool 30, push rod 60 and stopping means 40.
Please in conjunction with shown in Figure 2, protecting cover 20 is cup-like structure, the diameter of these protecting cover 20 inwalls is greater than the diameter of urceolus 50 first openings 51 outer walls, and these protecting cover 20 dismountable this urceolus 50 first openings 51 that envelope, be used for preventing that when not using the medicine that is stored in vagina and the cervix uteri administration injector 10 from spilling, as long as in use this protecting cover 20 is pulled down.
Please in conjunction with shown in Figure 5, urceolus 50 is hollow tubular structure, be respectively first opening 51 and second opening 53 at the two ends of this urceolus 50, and the first opening inner diameter is less than the second opening inner diameter, the outer wall of its first opening 51 is smooth, can not injure bodily tissue in use, not have sensation of pricking and do not have foreign body sensation, its length meets women's physiological structure, can guarantee that medicine can accurately send to the position of cervix uteri.Its second opening 53 has half ring cylindrical groove 531, and the both sides of groove are provided with groove 5311, and there is a groove 533 groove 531 middle parts perpendicular to this groove 531, and groove 531 and 533 is used for the orbit of restriction push rod 60 and the fixing position of push rod 60.The outer wall of second opening 53 of this urceolus 50 is provided with external screw thread 535, and the inwall of spring spool 30 openings 31 is provided with female thread 311, and rotation urceolus 50 and spring spool 30 can be fastenedly connected.
Please in conjunction with shown in Figure 3, spring spool 30 is a band round bottom seat 33, the cylindrical structural of hollow, and the inwall of opening 31 is provided with female thread 311, and bottom 35 is stainless steel spring 351 1 ends fixedly.During use, promote pusher button 61, have that stainless steel spring 351 provides power in the spring spool 30, promote push rod 60 medicine is directly launched out urceolus 50 first openings 51.
Please in conjunction with shown in Figure 4, stopping means 40 is the semi-ring column construction, and there is the card article 411 of protrusion its both sides 41, and card article 411 can be chimeric mutually with the groove 5311 of urceolus 50 second open-ended slot 531 both sides.Stopping means 40 pushes from groove 531 1 ends, stopping means 40 and urceolus 50 are firmly coincide, be used for preventing in transportation, this vagina and cervix uteri administration injector 10 are jolted, are shaken and collided, make push rod 60 rotations after pusher button 61 is stressed, and then prolong groove 531 and promote, make that the medicines in the host cavity 55 spill in this urceolus 50.Stopping means 40 1 ends are for pushing away handle 43, and this pushes away handle is a cuboid projection, can make things convenient for push-and-pull during use.
Please in conjunction with shown in Figure 6,60 fens four parts of push rod, pusher button 61, push rod push away medicine end 63, push rod bottom 65, push rod mid portion 67.Pusher button 61 is the protrusion cylindrical structural, play the screens effect, push rod 60 is shifted spring spool 30 bottoms onto can make the spring compression to groove 533 little rotations, the anti-pusher button 61 that pushes away during use, push rod bottom 65 is subjected to stainless steel spring 351 restoring forces can make push rod 60 produce thrust, and then medicine is directly released urceolus 50 first openings 51.Push rod pushes away medicine end 63 external diameters and equals urceolus 50 first openings 51 internal diameters, can make in the urceolus 50 that medicine is unlikely in the host cavity 55 spills.Push rod bottom 65 external diameters are less than urceolus 50 second openings 53 internal diameters.Push rod mid portion 67 external diameters equal half of urceolus 50 first openings 51 internal diameters, so both can reduce the friction of push rod 60 and urceolus 50 inwalls, can reduce the material use amount again, and attractive in appearance.
During assembling, at first the pusher button 61 of push rod 60 is aimed at the groove 531 of urceolus 50 second openings 53; Then push rod being pushed away medicine end 63 passes these urceolus 50 second openings 53 and is pushed into first opening, 51 places; Subsequently, spring spool 30 openings 31 are aimed at urceolus 50 second openings 53, rotating spring sleeve 30 is fastenedly connected it; Then pusher button 61 is pushed into 533 places through groove 531, takes then to push away handle 43, make stopping means alignment slot 531, push urceolus second opening 53 to by urceolus 50 first openings 51, stop when arriving spring spool 30 openings 31 promoting, this moment, push rod 60 was fixing; Again medicine is put into the host cavity 55 of urceolus 50; At last, protecting cover 20 is enveloped first opening 51 of urceolus 50.
During use, take off protecting cover 20, pull out stopping means 40, to one group gently in groove 531 directions, push rod 60 is subjected to spring 351 elastic force the direct bullet of medicine can be delivered to cervix uteri oral area position with the pusher button 61 of push rod 60.
This vagina and cervix uteri administration injector 10 are applicable to tablet, powder, capsule, suppository or granules medicine.
The utlity model has following advantage:
Use stopping means 40, can prevent in transportation, when this vagina and cervix uteri administration injector were jolted, shaken and collide, the medicine in push rod 60 stressed these urceolus 50 of back extruding in the host cavity caused it and spills.During use, take off protecting cover 20, pull out stopping means 40, gently dial pusher button 61, use spring 351 restoring forces as thrust, push rod 60 can eject medicine, and stepless action is in vagina and cervix uteri patient part, accurate positioning.Simultaneously, the hommization of administrator height makes things convenient for self-administration; Disposable use, cross infection is avoided in safety and sanitation.
