Abstract

The invention discloses a kind of syringes, including a syringe, a syringe needle and two pistons；One end of syringe is set there are two chamber is slided, and is equipped with partition between this two sliding chambers；The other end of syringe is equipped with boss, and boss is set there are two fluid hole, and each fluid hole is connected to a corresponding sliding chamber；Syringe needle is set on boss；Each piston is plugged in corresponding one sliding chamber.Present invention has the advantage that need to only penetrate can once inject at least two medical fluids, sufferer pain is effectively reduced.

Description

Syringe

Technical field

A kind of medication injections structure-design technique of the present invention field, and in particular to syringe.

Background technique

When patient needs intramuscular injection a variety of liquid medicine, user can generally be mixed use, but for some special feelings For condition, injecting program has successively, such as in order to mitigate patient suffering, first injects anaesthetic, then inject healing potion, it is necessary to make User is injected respectively with multiple syringes, needs to prick out multiple pin holes.

Summary of the invention

The object of the present invention is to provide a kind of syringes for only pricking two kinds of medicaments of a pin hole, that is, injectable.

Realizing the technical solution of the object of the invention is: a kind of syringe, including a syringe, a syringe needle and two work Plug；One end of syringe is set there are two chamber is slided, and is equipped with partition between this two sliding chambers；The other end of syringe is equipped with boss, and boss is set There are two fluid hole, each fluid hole is connected to a corresponding sliding chamber；Syringe needle is set on boss；Each piston is plugged in a corresponding cunning In chamber.

Further, each piston includes a pull rod and a seal cap being adapted to sliding chamber.

Further, partition is a plate, and the shape of each sliding chamber is semicircle or arch.

Further, the pull rod of a piston is equipped with the bullet being adapted to partition end and hooks and for accommodating bullet hook Notch.

Further, the pull rod of another piston is equipped with for bullet to be hooked to the sliding pressure platform for being pressed into notch.

Further, sliding pressure platform is located at the outside of partition end.

Present invention has the advantage that need to only penetrate can once inject at least two medical fluids, sufferer pain is effectively reduced.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of the invention；

Fig. 2 is a kind of structural schematic diagram of the syringe when bullet catches on partition end shown in Fig. 1；

Fig. 3 is a kind of structural schematic diagram of the syringe shown in Fig. 1 when bullet hook is pressed into notch by sliding pressure platform.

Appended drawing reference are as follows: syringe 1, sliding chamber 11, partition 12, partition end 121, needle holder 13, fluid hole 14, syringe needle 2 are living Plug 3, pull rod 31, seal cap 32, bullet hook 41, notch 42, sliding pressure platform 43.

Specific embodiment

(embodiment 1)

The present embodiment is a kind of syringe, as shown in Figure 1, including 1, syringe needle 2 of a syringe and two pistons 3；Syringe One end is set there are two chamber 11 is slided, and is equipped with partition 12 between this two sliding chambers；The other end of syringe is equipped with needle holder 13, and needle holder is set There are two fluid hole 14, each fluid hole is connected to a corresponding sliding chamber；Syringe needle is set in needle holder；Each piston is plugged in corresponding one In a sliding chamber.Each piston includes a pull rod 31 and a seal cap 32 being adapted to sliding chamber.Partition is a plate, each sliding chamber Shape be semicircle or arch.

In the present embodiment, only one duct of syringe needle, the duct is connected to simultaneously with two fluid holes.

In use, at least two medical fluids (each sliding chamber Chinese medicine liquid can be mixed liquor) are taken out respectively first with two pistons Into in each sliding chamber, when injection, according to predesigned order medical fluid through needle injection into muscle.

The present embodiment, which has an advantage in that only penetrate, can once inject at least two medical fluids, effectively reduce sufferer pain.

Treatment medical fluid is injected in order to meet some special injection requirements, such as after first injecting anaesthetic, to mitigate sufferer pain, The present embodiment is also equipped with the bullet being adapted to partition end 121 on the pull rod of first piston (piston on the right in Fig. 1) Hook 41 and the notch 42 for accommodating bullet hook；As shown in Figure 2, when the piston pull out to make bullet hook be located at partition end When holding outer, bullet hook is popped up from notch；The piston can be continued to pull out at this time, but when inwardly filling in, bullet hook will hook every On plate end, further filling in for the piston is hindered.

The pull rod of second piston (piston on the left side in Fig. 1) is equipped with for bullet to be hooked to the sliding pressure platform for being pressed into notch 43, sliding pressure platform is located at the outside of partition end；As shown in Figure 3, when the piston is pushed into the position for having injected medical fluid, sliding pressure platform The bullet hook of first piston is pressed into notch, so that first piston can be moved towards close to the direction of syringe needle.

The advantages of this structure, is: after two pistons are pumped into medical fluid, being made by the way that first piston to be pulled to It is when its bullet is hooked in partition end, i.e., certifiable first to inject second piston, first piston is injected afterwards, it is ensured that it injects secondary Sequence, to meet some special injection requirements.
