CN203107863U - Puncture syringe - Google Patents

Abstract

The utility model discloses a puncture syringe which comprises a syringe tube, wherein a piston is arranged inside the syringe tube and is connected with a piston push rod. The puncture syringe is mainly characterized in that finger rings are respectively arranged on two sides of the rear part of the syringe tube and the tail end of the piston push rod. In the use process of the puncture syringe by medical staff, thumbs, index fingers and middle fingers are inserted into ferrules for sucking. The application of the puncture syringe is especially suitable for positioning puncture guided by imaging; and meanwhile, single-hand operation can be realized, the complexity of operation is reduced and the working efficiency is increased.

Description

a puncture syringe

technical field

The utility model relates to a medical device, in particular to a puncture syringe.

Background technique

In modern medicine, injection is an extremely important link in the medical operation process. Therefore, the rationality of the injection technology or the use of injection equipment has an extremely important relationship with the quality of the final operation. Looking at the syringes currently used, the two sides of the end of the injection tube and the end of the piston push rod are simply attached with a sheet-like structure. Although this structure can complete the injection operation, it lacks stability and is generally not suitable for One-handed operation, so when the medical staff injects the patient, they need to operate with both hands at the same time. This process not only has a certain inconvenience in operation, but also greatly reduces the work efficiency of the medical staff, and also increases the work of the medical staff. Difficulty, so that it also has a certain impact on the quality of the work completed.

Utility model content

The purpose of the utility model is to provide a puncture syringe which is simple in structure, convenient in operation and can be operated by one hand. In order to achieve the above purpose, the utility model adopts the following technical solutions: a puncture syringe, including a syringe, the interior of the syringe has a piston, the piston is connected with the piston push rod, and it is characterized in that: the two sides of the rear part of the syringe are connected to the piston. The ends of the push rods are respectively provided with finger rings.

The radius of the ring is 0.7cm.

The utility model does not have too complicated changes in the structure, and in the operation process, the needle tube can be fixed on the three fingers through the annular collar, so as to realize the activity of operating the syringe with one hand, and at the same time, it can easily improve the efficiency of the injection process. Accuracy, such as applied to positioning puncture under imaging guidance.

Description of drawings

Figure 1 is a schematic structural view of the utility model.

Among the figure: 1 is the injection tube, 2 is the first finger ring, 3 is the second finger ring, 4 is the piston push rod, and 5 is the piston.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in Figure 1, a kind of puncture syringe, the first finger ring 2 is positioned at the both sides of the end of syringe 1 and is connected with syringe 1 , and the second finger ring 3 is positioned at the end of piston push rod 4 and is connected with piston push rod 4, and piston 5 The head end of the piston push rod 4 is connected to each other. During the process of pushing and pulling the push rod, the piston operator inserts the index finger and middle finger into the two rings respectively to control the direction of the injection tube 1; inserts the thumb into the second ring 3 , to realize the control of the piston 5, stretch the thumb outward to realize the drug intake and other similar operations, and compress the thumb inward to realize the drug injection and other similar operations, thereby completing the injection process. The whole process is simple to operate and only needs one Control the injection operation with only one hand.

Wherein the radius of finger ring is 0.7cm, also can be other radius certainly, as 0.5cm, 0.8cm, 1cm, 1.1cm etc., can adopt different radius according to different needs, and this is all possible.

Claims (1)

1. A puncture syringe, comprising an injection tube, the inside of the injection tube has a piston, and the piston is connected to the piston push rod, and it is characterized in that: both sides of the rear portion of the injection tube and the end of the piston push rod are respectively provided with finger rings; The radius of the ring is 0.7cm.
