Medical needle aid

Abstract

The invention belongs to the technical field of medical devices, and in particular to a medical needle aid. The medical needle aid comprises a base, a needle base mounted on the base and a needle mounted under the needle base; the top of the base is fixedly connected with an outer cylinder; the interior of the outer cylinder is provided with a pull rod; and the bottom of the pull rod is fixedly connected with a push rod. According to the invention, a suction disc can be well adhered to a skin after the suction disc is adhered to a specified place, then an index finger and a middle finger of ahand pull the pull rod by a motion similar to a process of pulling a nail by a nail hammer, and then the needle quickly pierces a skin under action of an elastic part, so that a needle aiding effect is realized. In a process that the push rod pulls an elastic film up, the volume of gas in an empty slot becomes larger, and a negative pressure effect is produced; the negative pressure effect strengthens the negative pressure effect of the suction disc, so that the adhering effect of the suction disc on the skin is better; and finally, a part of the suction disc is lifted, the suction disc is separated from the skin, and the base is quickly removed from the skin, so that convenience of use is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a medical needle aid. Background technique [0002] A kind of dynamic blood sugar monitoring system appears on the market now. The continuous blood glucose monitoring system (RGMS) is a new type of continuous continuous blood glucose monitoring system put into clinical use in recent years. It is connected with a probe similar to a needle, and the probe is gently inserted into the subcutaneous tissue of the abdomen. The diameter of the probe head is very small, and the patient has no obvious pain and discomfort when it is inserted. The instrument receives an electrical signal reflecting the change of blood sugar from the detection head at a certain time interval, and converts the average value of the electrical signal collected multiple times into a blood sugar value and stores it. Hundreds of blood glucose values ​​can be recorded every day. The continuous blood glucos...

Problems solved by technology

[0003] Since the existing needle aids are used to prevent the user from falling from the arm due to stress, the needle aid needs to be tied to the arm, and when it needs to be unloaded, it needs to be Other personnel assist, otherwise one hand cannot be disassembled, which reduces the convenience of use. In view of this, the present invention provides a medical needle aid, which can quickly and independently remove the needle aid from the arm, improving the use convenience
