Embodiment Construction

[0042] like Figure 1-8 shown, see Figure 1~4 , the anesthesia injection device of the present invention comprises

[0043] The puncture needle 100 can be equipped with a catheter or a needle core inside;

[0044] The orifice plate 200 has a first through hole 201 in its middle, the puncture needle 100 faces the first through hole 201, and it is fixed at the place where the needle needs to be inserted by the patient through the fixing belt 202;

[0045] The connecting plate 300 is hinged at one end to the orifice plate 200, and hinged at the other end to the support frame 301, and the connection plate 300 and the support frame 301 are fixed by bayonet pins 302 to adjust the bending angle of the connecting plate 300 and needle insertion angle;

[0046] The needle insertion module 400 is configured on the connecting plate 300 , and uses the first guide cylinder 401 to guide the puncture needle 100 to be inserted directly against the first through hole 201 of the orifice plat...

Abstract

The invention discloses an anesthesia injection device. The anesthesia injection device comprises a puncture needle (100), a pore plate (200), a connecting plate (300) and a needle feeding module (400), wherein the needle feeding module (400) is arranged on the connecting plate (300), and is used for guiding the puncture needle (100) by a first guide cylinder (401) to be aligned with a first through hole (201) of the pore plate (200) for needle feeding. According to the device, the connecting plate (300) and a support frame (301) are fixed through a clamping pin, so that the needle feeding direction of the puncture needle (100) guided on the needle feeding module (400) is adjusted, and the puncture needle (100) is guided and supported; and the problems of local infection, deepened injury degree, increased pain of a patient and the like caused by shaking or too slow manual operation in the needle inserting process are avoided, so that the needle feeding quality of the puncture needle (100) can be ensured, the needle feeding difficulty is simplified, the surgical operation quality of the patient is improved, and the pain of the patient is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to an injection device for anesthesia. Background technique [0002] The most common surgical procedure in which anesthesia is injected is an epidural. [0003] Epidural anesthesia refers to epidural space block anesthesia, that is, local anesthetics are injected into the epidural space to block the spinal nerve root and temporarily paralyze the innervated area, which is called epidural space block anesthesia, or dura mater for short external block. According to the way of administration, it can be divided into single method and continuous method. According to the puncture site, it can be divided into high, middle, low and caudal block. [0004] Epidural puncture techniques include 17-gauge dural puncture needle, epidural catheter, non-resistance syringe, ordinary syringe, [0005] The steps of the above-mentioned epidural puncture technique are as follows: [0006] 1. The epidural puncture ...
