Description

Urgent need formula syringe

Technical field

This utility model relates to a kind of syringe, and more particularly it is a kind of a kind of urgently needed formula syringe that drug packaging and function of injection can be integrated.

Background technology

At present, the used injection drug of medical department all adopts cillin bottle or ampoule packing, during use, be earlier with syringe (or earlier solvent is injected in the cillin bottle, dissolve medicated powder after) medicinal liquid is sucked needle tubing, does intramuscular injection or dosing in infusion bottle to patient again.This mode of operation had both been wasted packaging material, had increased the weight of nurse's labor intensity simultaneously, and the program complexity wastes time and energy, and also had because of misoperation or syringe use repeatedly, caused problems such as infection.

In recent years, developed some prefilled syringes, Syringes with reservoir, Syringe with medicine in it etc., this class syringe is complex structure mostly, and a piston catch bar is mostly arranged, so its sealing property can not get guaranteeing, and its operating process is also complicated.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned existing disadvantages of background technology part, and a kind of urgently needed formula syringe is provided.It is a kind ofly medicine can be preserved the syringe that unite two into one with function of injection, and instant packed, transportation and using.

The purpose of this utility model reaches by following measure: urgently needed formula syringe, it comprises the cillin bottle 1 that has seal cover 1-1, it also comprises plastic sheath 2-1 and following plastic sheath 2-2, upper end in the last plastic sheath 2-1 pivot bush unit infra plastic sheath 2-2, last plastic sheath 2-1 inner bottom part is fixed with double needle 3, cillin bottle 1 is the pressurization cillin bottle, and the cervical region of described cillin bottle 1 is fixed in down the bottom of plastic sheath 2-2.

In technique scheme, be fixed with spring 4 on the bottom of described upward plastic sheath 2-1 or the double needle 3, the cavity of plastic sheath 2-2 and the top of cillin bottle 1 under described spring 4 is positioned at.

In technique scheme, have L type groove 2-21 on the described following plastic sheath 2-2, described going up on the plastic sheath 2-1 has projection 2-11, and described projection 2-11 is positioned at L type groove 2-21.

In technique scheme, described plastic sheath 2-2 down is that the upper end is big, the little interior empty column construction in lower end, and the width of the described lower end of plastic sheath 2-2 down is wide less than the bottle of pressurization cillin bottle 1.

In technique scheme, there is projection 2-12 described centre of going up the bottom of plastic sheath 2-1, and described double needle 3 is fixed on the middle part of projection 2-12.

In technique scheme, rubber sleeve 5 on the described double needle of going up in the plastic sheath 2-1 3.

In technique scheme, two end syringe needles of described double needle 3 are 10-45 °.

In technique scheme, on the described rubber sleeve 5 plastic sheath 6 is arranged.

This utility model urgent need formula instrument used for injection has following advantage: 1. convenient and practical, reduced the operating procedure of injecting, and can reduce the incidence rate that the meaning place infects greatly; 2. a large amount of drug packing materials be can save and transportation and storage are convenient to; Urgent rescue when 3. being particularly suitable for battlefield or first aid; 4. simple in structure, easy to use.

Description of drawings

Fig. 1 is the STRUCTURE DECOMPOSITION figure of this utility model urgent need formula syringe;

Fig. 2 is the connection diagram that goes up plastic sheath and following plastic sheath in this utility model urgent need formula syringe.

The specific embodiment

Below in conjunction with the performance of accompanying drawing detailed description this utility model urgent need formula syringe, it is clear and easy to understand that advantage of the present utility model like this will become.

1 is that cillin bottle, 1-1 are that seal cover, 2-1 are that last plastic sheath, 2-11 are that projection, 2-12 are that projection, 2-2 are for plastic sheath, 2-21 are that L type groove, 3 is that double needle, 4 is that spring, 5 is that rubber sleeve, 6 is plastic sheath down among the figure.

This utility model urgent need formula syringe, it comprises the cillin bottle 1 that has seal cover 1-1, upper end in last plastic sheath 2-1 and the following plastic sheath 2-2, last plastic sheath 2-1 pivot bush unit infra plastic sheath 2-2, last plastic sheath 2-1 inner bottom part is fixed with double needle 3, and two end syringe needles of double needle 3 are 10-45 °.Use double needle to be used for injection by an end, the other end is used to wear out the seal cover 1-1 on the cillin bottle 1.Cillin bottle 1 is the pressurization cillin bottle, and the cervical region of described pressurization cillin bottle 1 is fixed in down the bottom of plastic sheath 2-2.

Be fixed with spring 4 on the bottom of last plastic sheath 2-1 or the double needle 3, the upper end of the cavity of plastic sheath 2-2 and pressurization cillin bottle 1 under spring 4 is positioned at.Have L type groove 2-21 on the following plastic sheath 2-2, on the last plastic sheath 2-1 projection 2-11 is arranged, projection 2-11 is positioned at L type groove 2-21, when pressing plastic sheath 2-1 instantly, downforce acts on the spring 4, make spring 4 compressions, at this moment going up projection 2-11 on the plastic sheath 2-1 moves down earlier in L type groove 2-21 and rotates the location, back, the seal cover 1-1 that makes the fixed double needle 3 of plastic sheath 2-1 inner bottom part wear out cillin bottle 1 simultaneously enters in the pressurization cillin bottle 1, thereby the medicinal liquid in the pressurization cillin bottle 1 is flowed out automatically, finish injection process.

Following plastic sheath 2-2 is that the upper end is big, the little interior empty column construction in lower end, and the width of the lower end of following plastic sheath 2-2 is wide less than the bottle of pressurization cillin bottle 1, and when this structure pressed down plastic sheath 2-1, it was more accurate to locate.The height of L type groove 2-21 also is to go up the location height that plastic sheath 2-1 presses down simultaneously.

There is projection 2-12 the centre of the bottom of last plastic sheath 2-1, and double needle 3 is fixed on the middle part of projection 2-12.Projection 2-12 has strengthened the fixedly contact area of double needle 3 of last plastic sheath 2-1, makes the fixing more firm of double needle 3.

Rubber sleeve 5 on the double needle 3 in the last plastic sheath 2-1, on the rubber sleeve 5 plastic sheath 6 is arranged simultaneously, this structure helps more preventing that double needle 3 from avoiding polluting, and only needs during use rubber sleeve 5, plastic sheath 6 are taken off and get final product.

Need to prove: to those of ordinary skill in the art, can also make some changes or distortion to this utility model under the prerequisite that does not change this utility model principle, this belongs to protection domain of the present utility model equally.
