Embodiment 1

[0021] like figure 1 and figure 2 As shown, this embodiment discloses a medical painless chest drainage tube, which includes a drainage tube body 1, on which a drug bag 2 for diffusing anesthetics is provided, and one end of the drug bag 2 is connected to an infusion tube 4 at one end 4b. The medicine capsule is a structure 2a with micropores on the surface. Wherein, the proximal end of the drainage tube body 1 is the end A shown in the figure, and the distal end is the end B shown in the figure.

[0022] After the infusion tube passes through the side wall 1a of the drainage tube body and is drawn out from one end of the medicine bag, at least an extended part 4a is located inside the drainage tube body, and then passes through the side wall 1a of the drainage tube body. The inner wall of the drainage tube body is provided with a groove, and the part 4a of the infusion tube located inside the drainage tube body 1 is fixed in the groove, forming an integral structure with ...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is that the drug capsule is made of a semi-permeable membrane capable of permeating the anesthetic liquid or a polymer one-way conductive membrane. The outer wall of the drainage tube body is provided with a groove, and after the infusion tube is led out from one end of the medicine bag, it is partly fixed in the groove to form an integral structure with the drainage tube body.

[0026] All the other parts are identical with embodiment 1.

Abstract

The invention discloses a medical painless chest drainage pipe. The medical painless chest drainage pipe comprises a drainage pipe body, a membranous anther sac, an infusion tube and a connector thereof and a marker line, wherein the drainage pipe body is sleeved with the membranous anther sac of a special structure, and the infusion tube and the connector thereof are connected with the anther sac. In the practical application process of the drainage pipe, the anther sac structure is left in a muscle nerve tissue area under human skin, meanwhile, local anesthetic is injected to the anther sac through the infusion tube with a microsyringe, by means of the anther sac of the special structure, the local anesthetic is overflowed into soft tissue under skin, nerve endings are narcotized, and the effect of local analgesia is achieved. After a cardiac and thoracic surgery or an abdominal surgery is conducted, by means of the cooperation of the painless chest drainage pipe, the muscle nerve tissue of the drainage area is subjected to local anaesthesia, and the local pain on account of the drainage pipe of a patient can be reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a medical painless chest drainage tube. Background technique [0002] Fluid or gas accumulation after thoracic surgery is a common clinical condition, and body cavity drainage tubes for such diseases are widely used. For example, after thoracic surgery, it is often necessary to place a chest drainage tube to drain pleural effusion, pneumothorax, hemorrhage, etc. This kind of chest drainage tube often needs to be left in place for several days or even weeks depending on the condition. During this period, the pain at the contact point between the drainage tube and human tissue is unbearable for the patient, especially when the patient coughs or takes a deep breath, the pain is more severe. In order to delay the patient's pain, the commonly used method in clinical practice is to inject analgesics such as morphine and duridine, but these analgesics are only effective for a few hours a...
