Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
It is provided by Fig. 1-3, the utility model includes syringe 1, piston core pin 2 and steel needle 3, the piston end 2a of piston core pin 2 Syringe inner cavity is protruded into from the oral area of 1 rear end of syringe, and steel needle 3 is mounted in the front end of syringe 1, the inlet of steel needle 3 and piston core pin Syringe inner cavity between piston end constitutes suction type sliding stroke chamber 1a, and piston core pin is slided forwards, backwards along syringe inner cavity length, structure At compression injection structure, it is provided with the sliding sleeve 7 being connected with 1 front end of syringe on the outside of steel needle 3, is set on steel needle 3 along its length That slides forwards, backwards is slidingly sealed column 4, is provided with and is slidingly sealed the storage needle that column 4 is fixed together between sliding sleeve 7 and steel needle 3 Sliding sleeve 7 is stretched out in set 10, the front end of storage needle guard 10, is connected on 4 front end face of sealing column and is fixed together with storage 10 front end of needle guard And stretch out the casing 5 of storage needle guard front end, steel needle 3 protrudes into storage 10 inner cavity of needle guard, after sealing column 4 to preceding protruding into 5 inner cavity of casing, It stretches out on storage 10 outer wall of needle guard of 7 front end portion of sliding sleeve and is provided with the locating cover 6 extended radially, store up and set on 10 outer wall of needle guard It is equipped with elastic slice 8, location hole 9 corresponding with elastic slice 8 is provided on the outer wall of sliding sleeve 7, sliding sleeve is slid back and forth, works as sliding sleeve When 7 front ends are in contact with 6 rear end of locating cover, steel needle 3 stretches out the front end of casing 5, when elastic slice 8 is installed in location hole 9, steel needle 3 front end is in the casing between sealing column 4 and locating cover 6.
To guarantee using effect, the front end of the casing 5 is in shrink mouth shape.
The rear end of the piston core pin 2 is provided with handle 2b.
Scale is provided on the syringe 1.
The steel needle 3 is separated with 5 phase of casing, and steel needle 3 is separated with storage 10 phase of needle guard.
The section of the sliding sleeve 7, storage needle guard 10 and casing 5 is circular ring shape, and storage needle guard 10 is placed in sliding sleeve 7 Side, casing 5 are placed in 10 inside of storage needle guard.
The internal perisporium in the outside for being slidingly sealed column 4 and storage needle guard 10 is tightly connected.
The front end face of the locating cover 6 is flushed with the front end face of storage needle guard 10.
The locating cover 6 is connected through a screw thread with storage needle guard 10.
The elastic slice 8 is triangle or column elastic slice, can carry out control bullet by the elasticity of elastic slice itself, can also add Spring is compressed between sliding sleeve 7 and storage needle guard 10, when elastic slice slides into position of positioning hole, at itself when elastic slice does not pop up It is protruding under elastic force or spring force effect, it is stuck in positioning hole, slide both sliding sleeve 7 and storage needle guard 10 can not relatively It is dynamic, at this time in casing of the front end of steel needle 3 between sealing column 4 and locating cover 6, the injection of stable safety can be carried out.
When the utility model is used, piston core pin is pushed, the length of suction type sliding stroke chamber is compressed, by the feed liquor of steel needle Drug, outside pull piston core pin are protruded into end, and suction type sliding stroke cavity length is gradually increased, and under the action of negative pressure, draw medicine Object fills suction type sliding stroke chamber, and operator's right hand pen-holding type holds syringe 1, at this time 7 front end of sliding sleeve and 6 rear end phase of locating cover Contact, steel needle 3 stretch out the front end of casing 5, make an accurate selection of position straight thrust site of puncture, after inserting needle, stretch out storage 10 front end portion of needle guard Casing enters human body, and the outer diameter for storing up needle guard is greater than the outer diameter of casing, under the front end blocking for storing up needle guard, stops entering, left hand is pinned Locating cover 6 is allowed to be close to skin, and the right hand is held syringe 1 and pulled out outward, syringe drive steel needle 3 and sliding sleeve 7 relative to storage needle guard 10 to After slide, until storage 10 outer wall of needle guard on elastic slice 8 be installed in the location hole 9 on 7 side wall of sliding sleeve, at this time before steel needle 3 It holds in the casing between sealing column 4 and locating cover 6, i.e., steel needle is detached from body scale, and casing remains in infant body, right Medical fluid is pushed into infant body by hand by casing, is slidingly sealed column and is played the role of being slidingly sealed, prevents Drug leakage, is led to It crosses this mode to be injected, solves the problems, such as to carry out intramuscular injection, while steel needle after injection to baby, children in clinical position Needle point is in the protection of casing, and casing can be used the polyurethane material of commercially available venous detaining needle and be made, in this way due to staying Setting part is hose, even if infant is movable, the problem of needle point scratches muscle will not occurs, effectively prevent the hair that needle is stabbed It is raw, it is fixed after inserting needle by locating cover, prevents from shaking, then driven steel needle to be detached from human body by sliding sleeve and injected, it is anti-in this way Medical staff is stopped or family members, patient is wounded by stabbing, securely and reliably, easy to use, effect is good, is the innovation on syringe, has good Good social and economic benefit.
