A double lumen anesthesia catheter

Abstract

The invention discloses a double-chamber anesthesia catheter, which discloses an anesthesia catheter that can flexibly adjust the drug delivery position by changing the position of the guide rod to change the drug outflow position through the guide rod to open the elastic sheet. On one end of the conduit, two branch pipes are placed on the sealing cap, and two guide grooves are axially opened on the inner wall of the conduit, and the two guide grooves are symmetrical, the dividing plate is placed in the conduit, and the branch The two sides of the partition are respectively clamped in two guide grooves, the semicircular bottom plate is placed on the bottom end of the partition plate, the arc edge of the semicircular bottom plate fits with the inner wall of the conduit, and the partition plate cooperates with the semicircular bottom plate The inside of the catheter is divided into two cavities, and the two branch pipes communicate with the two cavities respectively. A release groove is axially formed on the wall of the catheter, and the release groove communicates with one of the cavities. The other of the catheter is There is a drug outlet hole in the middle of one end.

Description

technical field [0001] The invention relates to a double-lumen anesthesia catheter, which relates to an anesthesia catheter capable of performing double-lumen anesthesia, and belongs to the field of medical equipment. In particular, it relates to an anesthesia catheter that can flexibly adjust the position of the medicine out by changing the position of the guide rod to change the outflow position of the medicine by pushing the elastic sheet apart through the guide rod to make the medicine flow out. Background technique [0002] Anesthesia refers to the use of drugs or non-drug methods to temporarily lose sensation in the body or a part of the body in order to achieve painlessness. It is mostly used for surgery or the treatment of certain diseases. When performing local anesthesia, it is necessary to use an anesthesia catheter to deliver the anesthetic to the area that needs anesthesia. In the prior art, a catheter with a double-cavity structure is used, and multiple drug ou...

Problems solved by technology

[0002] Anesthesia refers to the use of drugs or non-drug methods to temporarily lose sensation in the body or a part of the body in order to achieve painlessness. It is mostly used for surgery or the treatment of certain diseases. When performing local anesthesia, it is necessary to use an anesthesia catheter to deliver the anesthetic to the area that needs anesthesia. In the prior art, a catheter with a double-cavity structure is used, and multiple drug outlet holes are provided, but because the position of the drug outlet hole is fixed, the position of the drug outlet hole cannot be adjusted after the catheter is inserted, and the drug outlet position cannot be flexibly adjusted during use. , during anesthesia, it may not be possible to anesthetize the point that needs anesthesia

[0003] The notification number CN2242104 discloses a double-cavity epidural anesthesia catheter, including a catheter and a drug outlet. The drug outlet of the device is set at different positions of the double chamber, and the position is fixed and cannot be adjusted. There are requirements for some anesthesia points , cannot be flexibly adjusted to meet anesthesia requirements
