Abstract
The utility model discloses a wave-shaped needle head type catheter used for continuous lumbar anesthesia, which belongs to the medical appliance and solves the technical problem that the catheter head and the catheter body of the traditional hard film medicine applying catheter are integrated and adopt a flat shape, thus the slippage is easily caused. The utility model adopts a structure that a thin needle head with number 5 or 6 is connected to the head part of the main body of a medicine applying catheter, the length a of the thin needle head is 1.5 cm to 3.5 cm, and the needle head adopts a wave shape. The utility model is used for performing anesthesia to the inner canalis vertebralis of a patient, a puncture needle is firstly pierced into the sclerosing liipogranuloma of the patient during use, and the wave-shaped needle head type catheter is inserted into the cavitas subarachnoidealis of the patient through the central hole of the puncture needle, thus the continuous lumbar anesthesia can be preformed. Because the wave-shaped needle head is arranged on the medicine applying catheter, the wave-shaped needle head type catheter is easy to be fixed at the cavitas subarachnoidealis and is not easy to slip, and the anesthesia is very convenient for implementation.
Description
Technical field
This utility model relates to medical apparatus and instruments, is the medical apparatus and instruments of continued narcosis in a kind of canalis spinalis specifically.
Background technology
Continuous spinal anesthesia is a kind of to implementing a new technique of anesthesia in patient's canalis spinalis.At first patient's subarachnoid space is punctured and indwelling during enforcement, import the dura mater delivery catheter by the puncture needle centre bore again, lead gradation injection in patient's canalis spinalis through the dura mater delivery catheter with puncture needle.The tube head of traditional dura mater delivery catheter and body are as a whole to be flat, causes slippage easily, need to insert in patient's spinal dura mater to fix, thus big to the spinal dura mater perforation, cause sequela such as patient's headache easily.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that solves prior art, prior art is improved the wave needle-based conduit that provides a kind of not eely continuous spinal anesthesia to use.
The purpose of this utility model is achieved in that it comprises the delivery catheter body, it is characterized in that, is connected with No. 5 or No. 6 fine needle heads at delivery catheter body head, and fine needle head length degree is a=1.5-3.5cm, and described syringe needle is wavy.
Good effect of the present utility model is: thrust patient's spinal dura mater with puncture needle earlier during use and by the puncture needle centre bore this utility model is inserted patient's subarachnoid space, can administration implement continuous spinal anesthesia.Owing to be with wavy syringe needle on the delivery tube, be easy to be fixed on subarachnoid space and be difficult for slippage, implement anesthesia easily.
Description of drawings
Fig. 1 is structure of the present utility model and user mode figure.
Marginal data: 1-delivery catheter body; 2-puncture needle; 3---the fine needle head.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
As shown in the figure, this utility model comprises delivery catheter body 1, is connected with No. 5 or No. 6 fine needle heads 3 at delivery catheter body 1 head, and fine needle head 3 length are a=1.5-3.5cm, and described fine needle head 3 is wavy.During use, earlier puncture needle 2 is penetrated the vertebra dura mater, again this utility model is imported patient's subarachnoid space.By the low dose of intermittent administration of conduit, realize continuous spinal anesthesia.
Claims (1)
1. wave needle-based conduit that continuous spinal anesthesia is used, it comprises the delivery catheter body, it is characterized in that, is connected with No. 5 or No. 6 fine needle heads at delivery catheter body head, and fine needle head length degree is a=1.5-3.5cm, and described syringe needle is wavy.
