The specific embodiment

Below in conjunction with accompanying drawing this utility model is further described:

Shown in accompanying

drawing

1,2,3,4,5:

A kind of novel disposable syringe, it comprises paper syringe 1, paper push rod 2, syringe needle rubber holder 3, piston rubber sleeve 4, the standard needle of being made up of inner core and urceolus 5; The inner core of the middle paper card 6 that is arranged on paper syringe 1 inner underside and the following cardboard 7 that is arranged on paper syringe 1 bottom and paper syringe 1 is by bonding naturally formation one confined space of high temperature; Syringe needle rubber holder 3 fixed covers are inserted and are connected in the described confined space, all offer the through hole that can supply liquid medicine to free in and out in the centre of middle paper card 6 and syringe needle rubber holder 3, and the lower end of syringe needle rubber holder 3 is then connecting standard needle 5; Paper push rod 2 parts are plugged in the paper syringe 1, last paperboard 9 and the following paperboard 10 that be arranged on its bottom open space that form a placement piston rubber sleeve 4 of paper push rod 2 by being arranged on the outside, its lower end, have circular hole 11 in the described centre of paperboard 10 down, 11 places are bonded with thin paper sheet 12 at circular hole, and the top of paper push rod 2 is provided with the push rod cardboard 14 that has through hole 13; The last cardboard 15 that the centre has circular hole is bonded in the top of paper syringe 1 and forms plug-type little matched in clearance with paper push rod 2, prevents to play pendulum in the paper push rod 2 push-and-pull processes.In use, be provided with the viewing window of being made by transparent material 16 in paper syringe 1 side, described viewing window 16 is at least one, and it is used to observe the water-soluble amount of paper syringe giving drugs into nose.Form 16 is close to paper syringe 1 inner core whole periphery circle parcel by layer of transparent paper and is formed.Cellophane is by high temperature and the complete natural adhesive seal of paper syringe 1 inner core, and cellophane indicates the Rong Shengke degree at viewing window 16 places, and injection in the paper syringe 1 what are convenient to observe.Because the easy decomposition of thin paper sheet water breakthrough is broken crisp, and the through hole 13 on the push rod cardboard 14 communicates with following paperboard 10 intermediary circular holes 11, whole syringe can't form seal cavity, thereby scraps, and can't reuse in the use of reality.

Be provided with the grab 17 that is connected with standard needle 5 in the lower end of syringe needle rubber holder 3, the pulling force when increasing drawn needle prevents that standard needle 5 from pulling out easily from syringe needle rubber holder 3, uses safer.

All offer recessed draw-in groove at described paper syringe 1 and syringe needle rubber holder 3, recessed draw-in groove 18 of paper syringe and the recessed draw-in groove 19 of syringe needle rubber holder are connected, recessed draw-in groove 18 of described paper syringe and the recessed draw-in groove 19 of syringe needle rubber holder all have at least one, this is another fit system of paper syringe 1 and syringe needle rubber holder 3, and it can well be placed restrictions on syringe needle rubber holder 3 and move up and down.

This utility model is by natural paper material and natural rubber material, and no glue is bonded; Natural paper and natural rubber easily decompose back to nature with the recyclable processing in back, can not bring residue and pollution to environment; Really accomplish pure environmental protection, utilize paper water breakthrough easily dissolving and broken fragility, reach disposable use, can not recycle.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit this utility model practical range, so all equivalences of doing according to the described structure of this utility model claim, feature and principle change or modify, and are included in this utility model claim.
