Description

Sucker type L-shaped nerve block indwelling needle

Technical Field

The utility model relates to the technical field of medical equipment, more specifically say so and relate to a sucking disc formula L type nerve block indwelling needle.

Background

The continuous nerve block technology is that a catheter is precisely kept near a target nerve, and local anesthetic is injected near the target nerve through a catheter opening to achieve the purposes of anesthesia and pain treatment. The medical devices used in the continuous nerve block technology face two contradictory problems of safety and accuracy. The safety mainly means that the puncture needle can be carelessly punctured into the target nerve to cause nerve injury in the operation process, and the accuracy requires that the opening of the catheter is as close as possible to even contact the target nerve, so that the medicine can be favorably and accurately flowed onto the target nerve to play the medicine effect. The nerve block needle is a medical instrument designed by using the principle of continuous nerve block technology. The existing nerve block needle has single function and no retention condition, is generally used for one-time puncture, increases the pain of patient puncture for patients needing repeated puncture block in clinic and is easy to have clinical complications.

Therefore, how to provide a suction disc type L-shaped nerve block retention needle is one of the technical problems to be solved urgently in the field.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a sucking disc formula L type nerve block indwelling needle. The purpose is to solve the above-mentioned deficiency and offer.

In order to solve the technical problem, the utility model discloses following technical scheme has been taken:

a suction cup type L-shaped nerve block indwelling needle comprising: an indwelling cannula and a puncture needle body; a liquid medicine channel is arranged in the indwelling cannula; the puncture needle body is inserted into the liquid medicine channel, and the bottom end of the puncture needle body extends out of the bottom end of the indwelling cannula; a sucker and a medicine injection pipe are arranged on the periphery of the middle upper end of the indwelling sleeve; the medicine injection pipe is arranged above the sucker and is communicated with the liquid medicine channel; the top end of the indwelling sleeve is provided with a sealing plug for sealing the top end of the indwelling sleeve.

Preferably, the sealing plug is connected to the outer side wall of the top end of the indwelling cannula through a connecting band.

Preferably, the bottom end of the puncture needle body is provided with a needle head, and the top end of the puncture needle body is provided with a needle seat.

Preferably, the outer diameter of the puncture needle body is smaller than the inner diameter of the liquid medicine passage.

The utility model discloses for prior art gain following technological effect: the utility model discloses a sleeve pipe is kept somewhere in the setting, the liquid medicine passageway, injection pipe and pjncture needle body, after accomplishing the neural puncture, can be when extracting the pjncture needle body from the liquid medicine passageway, will keep somewhere the sleeve pipe and be kept somewhere the patient by blocking nerve next door, thereby can last to being blocked nerve department injection anesthetic through the injection pipe, and then can make the painful complications that minimize and avoid puncturing repeatedly and bring of puncture of patient's puncture, can fix the sleeve pipe through the sucking disc and on one's body the patient, prevent to keep somewhere the sleeve pipe and take place the skew and influence anesthesia effect.

Drawings

Fig. 1 is a schematic structural view of a suction cup type L-shaped nerve block indwelling needle of the present invention;

in the figure: 1. an indwelling cannula; 2. a puncture needle body; 21. a needle head; 22. a needle seat; 3. a suction cup; 4. a medicine injection tube; 5. a sealing plug; 6. a pipe plug; 7. a connecting belt.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1, the utility model discloses a sucking disc formula L type nerve block indwelling needle, include: an indwelling cannula 1 and a puncture needle body 2; a liquid medicine channel is arranged inside the indwelling cannula 1; the puncture needle body 2 is inserted in the liquid medicine channel, and the bottom end of the puncture needle body extends out of the bottom end of the indwelling cannula 1; a sucker 3 and a medicine injection pipe 4 are arranged on the periphery of the middle upper end of the indwelling cannula 1; the medicine injection tube 4 is arranged above the sucker 3 and is communicated with the medicine liquid channel; the sucking disc 3 is adsorbed on the skin surface of a patient, so that an indwelling needle can be fixed, and the indwelling cannula 1 can be fixed in the body of the patient, thereby facilitating the injection of liquid medicine and avoiding the pain of the patient caused by continuous puncture; keep somewhere sleeve pipe 1's top and be provided with the sealing plug 5 that is used for keeping somewhere sleeve pipe 1 top and sealing, after taking out pjncture needle body 2, use sealing plug 5 will keep somewhere sleeve pipe 1 top and seal to can avoid entering such as dust to keep somewhere the inside and prevent the liquid medicine outflow when injecting the liquid medicine of sleeve pipe.
