Syringe pressure generating and pressure displaying device

Abstract

The syringe pressure generating and pressure displaying device of the present invention is constituted in such a way that an auxiliary device is detachably joined to a cylinder flange while a rod bar is provided in the auxiliary device so as to pass therethough, and hand pressure on a lever that is hinge connected to the auxiliary device so as to be disposed horizontally in line with the syringe creates a rotational motion acting due to leverage, whereupon said rotational motion is converted to a linear motion via a motion-converting means, and the rod bar and a piston are moved with increased force.

Description

technical field [0001] The present invention relates to a pressure generation and pressure display device for a syringe, and more specifically relates to an injection operation for extracting human body tissue or injecting fat and medicine through a syringe, which can easily realize pressure generation through a single-handed grip, and A syringe pressure generator and pressure display device that can easily check the syringe pressure. Background technique [0002] A syringe refers to an appliance used to inject medicinal liquid into the tissue of a living body. Its structure includes: a front end combined with a needle; a cylinder (cylinder), which has an interference fit with the front end and has a space; , combined with the above-mentioned space, the pressure of the space is raised in conjunction with the pulling or pushing of the core rod, and the generated positive or negative pressure is used to inject medicine or extract human tissue through the needle.

Problems solved by technology

[0006] At this time, the injection action of the syringe with one hand is to advance or retreat the plunger while holding the flanges of the barrel and the plunger with fingers, but this injection action will increase the inconvenience and may cause Problems that lead to incorrect injection operations

[0007] In addition, when injecting a large amount of medicine into the human body using a large-capacity syringe or injecting a viscous medicine, if a large positive pressure occurs in the space of the syringe, there is a problem that the front end of the interference fit with the barrel will be separated.

[0008] On the contrary, in the case of fat grafting operation for correcting the shape of the body, when extracting viscous human body fat, if a large negative pressure occurs in the syringe space, there is a problem that it is difficult to perform the pulling operation of the core rod with one hand. The problem

[0009] At the same time, after the needle is inserted into the human body during liposuction, the plunger with the piston is pulled out to the rear of the syringe to generate negative pressure inside the syringe, and the fat is sucked into the space of the syringe through the needle. If the end of the needle is exposed to the air due to the operator's mistake, the negative pressure inside the syringe will disappear, making it impossible to continue sucking fat.

[0010] On the contrary, in the process of injecting medicine into the human body, the operator needs to apply a certain force according to the different viscosities of the medicine to generate positive pressure and inject the medicine, but if the positive pressure becomes too large accidentally, There is a problem that the injection of the human body constitutes damage to the surrounding tissue

[0011] To sum up, the syringe can stably generate positive pressure or negative pressure, which depends entirely on the physical resistance sensed by the operator with his hands. Therefore, it is difficult to accurately extract fat and inject drugs. The problem
