Embodiment 1

[0024] Such as Figure 1-Figure 3 As shown, an anesthesia needle convenient for continuous injection includes a needle 1, a syringe 3, a push rod 4, and a piston 5. The syringe 3 is sleeved with a support sleeve 6 on the side close to the needle 1. The support sleeve 6 is a transparent cylindrical structure, the second end 62 of the support sleeve 6 is connected to the side wall of the syringe 3, and the support sleeve side wall 63 of the support sleeve 6 is a retractable rubber structure, so The first end surface 61 of the support sleeve 6 has a flat structure, and the first end surface 61 is also provided with a matching hole 64 for the needle 1 to pass through.

[0025] The first end surface 61 is also bonded with a silicone layer, which can protect the skin and adapt to the shape of the injection skin surface, so that the fit is closer. The second end surface 62 is detachably installed on the side wall of the syringe 3, and it can be determined whether to install the support...

Embodiment 2

[0027] The difference between this embodiment and embodiment 1 lies in that figure 1 As shown, the needle 1 is provided with a number of indicator belts 2, the colors of the indicator belts 2 are different, and all the indicator belts 2 are arranged at even intervals.

[0028] The doctor can determine the depth of the needle according to the position of the indicator belt, which reduces the subjectiveness of the doctor's injection, thereby assisting the doctor to better control the depth of the needle. The colors of the indicator belts are different, so that the doctor can make judgments based on the different colors of the indicator belts.

Abstract

The invention discloses an anesthetic needle that is convenient for continuous injection; the anesthetic needle comprises a needle head, a syringe, a push rod and a piston; one side, close to the needle head, of the syringe is sleeved with a support sleeve that is in a transparent cylindrical structure; a second end face of the support sleeve is connected on the side wall of the syringe; the support sleeve side wall is a telescopic rubber structure; a first end face of the support sleeve is a flat structure, and provided with a mating hole that allows the needle head to penetrate. When long time anesthetic injection is needed, the first end face of the support sleeve can be directed attached to the skin, so the mutual contact pressure between the support sleeve and the skin can improve theneedle head stability in injection, thus reducing high hand concentration in long time continuous injection of the doctor, assisting the doctor to position and stabilize the needle head, and realizing long time continuous injection; the support sleeve is designed in a visual transparent structure and telescopic structure, so the doctor can conveniently observe the injection status and control theneedle head insert depth.

Description

Technical field [0001] The invention relates to an anesthesia needle, in particular to an anesthesia needle convenient for continuous injection. Background technique [0002] In some anesthesia operations, it is often necessary for the doctor to continuously perform anesthesia injections for a long time. The doctor needs to rely on his own experience to judge whether the needle depth is appropriate, and once the needle is inserted to the designated position, he needs to keep his hands highly concentrated for a long time. Ensure the stability of the needle. When a long-term continuous injection, the doctor's hands and eyes need to be highly concentrated, and the operation is very difficult. Summary of the invention [0003] The purpose of the present invention is to overcome the disadvantages of insufficient needle stability and difficulty in operation when doctors continue to inject for a long time in the prior art, and provide an anesthesia needle that is convenient for continuo...
