Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described, and the protection scope of the utility model is not limited to the following:

As shown in Figures 1 and 2, the present application provides a new type of syringe, which includes a syringe 1 and a needle 2 arranged on the end of the syringe 1. The syringe 1 is provided with a sliding groove 3 and a liquid medicine chamber 4, which slide The distance between the groove 3 and the needle 2 is smaller than the distance between the liquid medicine cavity 4 and the needle 2, and the sliding groove 3 is provided with a sliding block 5 that can slide along the extending direction of the sliding groove 3, and the sliding block 5 can be coupled to the liquid medicine through the connecting assembly 6 chamber 4, wherein, when the slider 5 slides, the volume of the liquid medicine chamber 4 can increase or decrease. After the needle 2 is inserted into the medicine bottle, the sliding block 5 is pushed to reduce the volume of the medicine solution chamber 4, and then the medicine solution can be sucked into the medicine solution chamber. After the needle 2 is inserted into the human body, the sliding block 5 is pushed to increase the volume of the liquid medicine cavity 4, and then the liquid medicine can be injected into the liquid medicine cavity. In the prior art, the liquid medicine cavity is located close to the needle, and the piston push rod is located away from the needle. After the needle penetrates the human body, the liquid medicine can be injected into the human body by pressing the piston push rod with a finger. In the above process, (1) when the needle is inserted into the human body, it is necessary for the medical staff to hold the bottom of the syringe (the closer the distance to the needle, the better), to ensure the stability of the needle during insertion. (2) After the needle is inserted into the human body, the medical personnel need to hold the syringe with one hand, and move the other hand to the top of the syringe so as to push the piston push rod with fingers. Therefore, when the prior art is in use, the single-handed operation of the medical personnel cannot be realized. When the application is in use, the medical personnel grasp the sliding groove position of the syringe with one hand (that is, the position near the lower part of the syringe), and the distance between the grasping position and the needle is relatively close, thereby ensuring the stability of the needle insertion process. At the same time, after the needle is pierced, the position of the hand does not need to be moved, and the medicinal liquid can be injected into the human body by simply pushing the sliding block 5 with the fingers, thereby realizing the one-handed operation of the medical staff.

Preferably, the connecting assembly 6 includes a connecting rod 6a and a piston 6b, the piston 6b is arranged in the liquid medicine chamber 4, one end of the connecting rod 6a is connected to the sliding block 5, and the other end of the connecting rod 6a is connected to the piston 6b, and the connecting rod 6a is connected to the piston 6b. In the case of sliding away from the needle 2, the volume of the liquid medicine cavity 4 can be reduced.
