Abstract

The utility model discloses a drug-dissolving syringe, which comprises a syringe, a core rod and a rubber piston. Two protruding rods are arranged on the curled long side at the end of the syringe body, and the protruding rods are parallel to the core rod when drawn out. , the length of the protruding rod is longer than that of the core rod, and the ends of the two protruding rods are connected and fixed on the push handle of the same protruding rod. A protruding rod parallel to the core rod is added to the crimp of the drug-dissolving syringe. The operator only needs to hold the core rod with the middle finger and index finger of the right hand, and press the protruding rod firmly with the thumb to complete the liquid extraction. At the same time, the protruding rod structure can also prevent the hands from touching the core rod during operation and contaminating the medicinal liquid. The medicine dissolving syringe can be operated with one hand and has the characteristics of convenience, quickness and safety.

Description

A dissolving syringe

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a drug-dissolving syringe.

Background technique

When using a drug-dissolving syringe for dispensing, medical staff need to extract the solvent, inject it into the drug to be dissolved, mix and dissolve, and then extract the drug solution into an infusion bottle or other drug delivery device. During this process, medical staff need to draw the liquid medicine several times. When the existing drug-dissolving syringe extracts the liquid medicine, more than two fingers need to be used to pull the plunger of the syringe, and the other fingers must hold the syringe, which is very inconvenient to operate with one hand and easily pollutes the plunger.

Contents of the invention

The technical problem to be solved by the present invention is that it is inconvenient to operate with one hand when extracting the medicinal liquid by the drug-dissolving syringe, and the core rod is easy to be polluted.

The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: a drug-dissolving syringe, including a syringe, a core rod and a rubber piston, two protruding rods are arranged on the curled long side of the end of the syringe body, and the protruding The rod is parallel to the core rod when drawn out, the length of the protruding rod is longer than that of the core rod, and the ends of the two protruding rods are connected and fixed on the push handle of the same protruding rod.

In a preferred embodiment of the above drug-dissolving syringe, the length of the protruding rod is not less than 10 mm longer than the core rod.

In a preferred embodiment of the above drug-dissolving syringe, the push handle at the end of the core rod is elliptical, and its long axis direction is perpendicular to the long axis direction of the elliptical crimp of the syringe.

The beneficial effects of the present invention are: a protruding rod parallel to the core rod is added to the crimp of the drug-dissolving syringe, the operator only needs to hold the core rod with the middle finger and index finger of the right hand, and press the protruding rod firmly with the thumb to complete the liquid extraction . At the same time, the protruding rod structure can also prevent the hands from touching the core rod and contaminating the medicinal liquid during operation. The medicine dissolving syringe can be operated with one hand and has the characteristics of convenience, quickness and safety.

Among the figure, 1 syringe, 11 needle cylinder crimping, 12 protruding rods, 13 protruding rod push handles, 2 core rods, 21 core rod push handles, 3 rubber pistons.

Detailed ways

As shown in Figures 1-5, a drug-dissolving syringe includes a syringe 1, a core rod 2 and a rubber piston 3. Two protruding rods 12 are arranged on the long side of the crimp 11 at the end of the barrel of the syringe 1. The protruding rod 12 is parallel to the core rod 2 when drawn out, and the length of the protruding rod 12 is longer than that of the core rod 2 , and the ends of the two protruding rods 12 are connected and fixed to the same protruding rod push handle 13 . The push handle 21 at the end of the core rod 2 is elliptical, and the long axis direction is perpendicular to the long axis direction of the elliptical curling edge 11 of the syringe.

During the dispensing process, when the medical personnel draw the liquid medicine, hold the index finger and middle finger of the right hand on the front part of the core rod push handle 21, and at the same time press the thumb on the convex rod push handle 13 on the syringe, and press firmly to draw the liquid medicine into the syringe When injecting the medicinal liquid, rotate the syringe 90° in the hand, hold the index finger and middle finger on the front part of the oval bead 11 of the syringe, press the thumb on the push handle 21 of the core rod, and press firmly to complete the injection of the medicinal liquid.

Claims (3)

1. a molten syringe comprises syringe, core bar and rubber piston, it is characterized in that, the long limit of the crimping of described syringe barrel tip is provided with two nose bars, the core bar of nose bar when extracting out is parallel, and nose bar length is longer than core bar, and two nose bar ends are connected and fixed on same nose bar and push away handle.

2. molten syringe according to claim 1 is characterized in that, nose bar length is longer than core bar and is not less than 10mm.

3. molten syringe according to claim 1 is characterized in that, the core bar end pushes away handle and is ellipticity, and its long axis direction is vertical with the oval crimping long axis direction of syringe.
