CN203227151U - Syringe core bar with six guide blades - Google Patents

Abstract

The utility model belongs to the field of medical appliances , and in particular relates to a six - piece guide piece syringe core rod . The front end of the core rod is processed with a core rod head, a piston is installed on the top of the core rod head, a core rod push handle is processed at the end of the six core rods, and six guide pieces are processed in the middle of the six core rods . Said, because the utility model is processed with guide plate 5 on the top of six core rods 4 , the cross section of six core rods 4 can be processed into very little like this, can save raw material greatly like this, because the effect of guide plate 5 is arranged, It can ensure that the six core rods 4 work stably and reliably in the syringe 1 .

Description

A syringe plunger with six guide pieces

technical field

The utility model belongs to the field of medical appliances, in particular to a syringe core rod with six guide pieces.

Background technique

At present, the core rods of clinically used syringes generally have a structural design that wastes raw materials. Because clinically used syringes are disposable, the waste is quite amazing. When medical staff suck medicine and inject, the syringe core rods are pushed and pulled. It is also more laborious, and the hands are easy to slip off from the edge of the coat, resulting in medical accidents.

Utility model content

The purpose of this utility model is just to overcome above-mentioned shortcoming, and a kind of syringe mandrel of five or six guide pieces is provided.

The utility model is realized in the following way: a syringe mandrel with six guide pieces, which is characterized in that a mandrel head is processed on the front end of the six mandrels, a piston is installed on the mandrel head, and a six-piece mandrel A core rod push handle is processed at the end of the rod, and six guide pieces are processed at the middle of the six core rods.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is the main sectional view of the utility model.

FIG. 2 is a cross-sectional view of “A-A” in FIG. 1 .

Fig. 3 is a cross-sectional view along "B-B" of Fig. 1 .

Fig. 4 is a "C-C" sectional view of Fig. 1 .

The labels in the figure are explained as follows:

1. Syringe, 2. Piston, 3. Core rod head, 4. Six core rods, 5. Guide plate, 6. Syringe flange, 7. Core rod push handle.

Detailed ways

The syringe 1 of the utility model adopts PP polypropylene material to be processed and formed in the mold at one time. The function of the syringe 1 is to store the liquid medicine and make the piston 2 slide in the syringe 1. Processing and molding, the function of the piston 2 is to inject the medicinal solution stored in the syringe 1 through the needle through the needle through the thrust of the core rod push handle 7, or inject the medicinal solution stored in the syringe 1 through the needle for other operations etc., the core rod head 3 is made of PP polypropylene material and processed in the mold at one time, and its function is to fix the piston 2. The upper piston 2 works stably and reliably. The guide plate 5 is made of PP polypropylene material and processed in the mold at one time. Its function is to ensure that the six-piece core rod 4 works stably and reliably in the syringe 1. The syringe flanging 6 is made of PP polypropylene. The material is processed and formed in the mold at one time, and its function is that the operation is convenient, stable and reliable during injection. The core rod push handle 7 is made of PP polypropylene material and processed in one time in the mold. Its function is to ensure that the six-piece core rod 4 works stably and reliably during work. .

In summary, the utility model can process the cross-section of the six core rods 4 into a very small size due to the fact that the guide plates 5 are processed on the six core rods 4, so that raw materials can be greatly saved. The role of the six-piece core rod 4 can be guaranteed to work stably and reliably in the syringe 1.

Claims (1)

1. the syringe core rod of six prerotation vanes, it is characterized in that: the front end at six core bars is processed with pin head, piston is installed on pin head, is processed with core bar at the end of six core bars and pushes away handle, be processed with six prerotation vanes at the medium position of six core bars.
