Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 1 and 2, the present application provides a novel syringe, including injection tube 1 and the syringe needle 2 that sets up on injection tube 1 tip, be provided with sliding tray 3 and liquid medicine chamber 4 on injection tube 1, the distance of sliding tray 3 and syringe needle 2 is less than the distance of liquid medicine chamber 4 and syringe needle 2, be provided with in the sliding tray 3 can follow the gliding sliding block 5 of the extending direction of sliding tray 3, sliding block 5 can couple to liquid medicine chamber 4 through coupling assembling 6, wherein, under the gliding condition of sliding block 5, the volume in liquid medicine chamber 4 can increase or reduce. After inserting syringe needle 2 into the medicine bottle, promote sliding block 5 and can inhale the liquid medicine in the liquid medicine chamber after making the volume in liquid medicine chamber 4 reduce. After inserting the syringe needle 2 into the human body, promote slider 5 and make the volume increase in liquid medicine chamber 4 back can be with liquid medicine injection liquid medicine chamber. In the prior art, the liquid medicine cavity is positioned at a position close to the needle head, the piston push rod is positioned at a position far away from the needle head, and after the needle head is penetrated into a human body, the piston push rod can be pressed by fingers so as to inject the liquid medicine into the human body. In the process, (1) when the needle head is penetrated into a human body, a medical worker is required to hold the lower part of the needle cylinder (the closer the distance to the needle head is, the better) so as to ensure the stability of the needle head in the penetrating process. (2) After the needle head penetrates into a human body, a medical worker needs to hold the needle cylinder by one hand and move the other hand to the position above the needle cylinder so as to push the piston push rod through fingers. Therefore, the prior art can not realize the one-hand operation of medical staff when in use. This application is when using, and medical personnel singlehanded catches the sliding tray position of injection tube (being the position that is close to the lower part of injection tube), and the distance of grabbing position and syringe needle is nearer to can guarantee that the syringe needle pierces the stability of process, simultaneously, the syringe needle pierces the back, and the hand position need not to remove, only needs to promote sliding block 5 through the finger and can pour into the liquid medicine human body, and then realizes medical personnel's one-hand operation.

Preferably, the connecting assembly 6 comprises a connecting rod 6a and a piston 6b, the piston 6b is disposed in the liquid medicine chamber 4, one end of the connecting rod 6a is connected to the sliding block 5, the other end of the connecting rod 6a is connected to the piston 6b, and the volume of the liquid medicine chamber 4 can be reduced under the condition that the sliding block 5 slides away from the needle 2. By the connection of the connection assembly 6, the synchronous movement of the piston 6b and the sliding block 5 can be realized.

Preferably, the syringe 1 includes a first cylinder 1a and a second cylinder 1b, and the first cylinder 1a and the second cylinder 1b are screw-coupled to each other. The liquid medicine cavity 4 is arranged in the first cylinder 1a, and the second cylinder 1b is provided with a placing cavity 7 for placing the piston 6 b. The first cylinder and the second cylinder can be detached and separated, so that the injection amount of the liquid medicine can be conveniently adjusted. For example, the liquid medicine chamber 4 can be provided with various different capacity specifications such as 2ml, 3ml, 5ml, and the like. Among the prior art, set up the scale on the injection tube usually, need medical personnel or patient oneself to absorb quantitative liquid medicine according to actual need and inject, but when the emergence needs urgent injection (for example patient breaks a disease suddenly, when the insulin of urgent need injection), patient oneself or medical personnel easy misoperation result in absorbing too much liquid medicine and inject. When the syringe is used, firstly, medical staff or patients can select a first cylinder with proper volume according to the requirement of injection amount in advance, and the first cylinder and the second cylinder are connected and assembled in advance for standby. When needing to inject, medical personnel or patient oneself can be directly inhale the liquid medicine with the liquid medicine chamber and fill up the liquid medicine to inject the liquid medicine into the human body and can accomplish the injection operation fast, can avoid appearing injecting excessive problem.

Preferably, the first cylinder 1a is provided with a first drainage channel 8, and the second cylinder 1b is provided with a second drainage channel 9. The first liquid discharge channel 8 is communicated with the liquid medicine cavity 4, and the second liquid discharge channel 9 is communicated with the needle head 2. When first barrel 1a and second barrel 1b are connected, first drainage channel and second drainage channel can align, and then make the liquid medicine in liquid medicine chamber 4 can inject into the patient internal through the syringe needle.

The working principle of this application does: when the syringe is used, firstly, medical staff or patients can select the first barrel with proper volume according to the injection quantity requirement in advance, and the first barrel and the second barrel are connected in advance and assembled for standby. When needing to inject, medical personnel or patient oneself can be directly inhale the liquid medicine with the liquid medicine chamber and fill up the liquid medicine to inject the liquid medicine into the human body and can accomplish the injection operation fast, can avoid appearing injecting excessive problem. During the injection, medical personnel singlehanded the sliding groove position of grasping the injection tube (being the position that is close to the lower part of injection tube), the syringe needle pierces the back, and the hand position need not to remove, only needs to promote sliding block 5 through the finger and can inject the liquid medicine into the human body.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof.
