Improved multipurpose abdominocentesis device for hepatopathy department

Abstract

The invention discloses an improved multipurpose abdominocentesis device which is novel in structural design, convenient to use, and easy to operate and is used for the hepatopathy department. The improved multipurpose abdominocentesis device comprises a puncture needle, an abdominal fluid suction pipe and an abdominal pressure decompression pipe, wherein the abdominal fluid suction pipe and the abdominal pressure decompression pipe are connected with the tail end of the puncture needle, a negative pressure adsorbing mechanism is connected to the front end of the abdominal pressure decompression pipe, and the tail end of the abdominal pressure decompression pipe and the tail end of the abdominal fluid suction pipe are communicated with the puncture needle through a connector; the connectorcomprises a pipe fitting of which the tail end is connected with the puncture needle, a first channel and a second channel are formed in the upper middle portion inside the pipe fitting, the lower end of the first channel is communicated with the lower end of the second channel through an inner cavity of the pipe fitting, the upper end of the first channel is communicated with the abdominal fluidsuction pipe, and the upper end of the second channel is communicated with the abdominal pressure decompression pipe; a penetrating hole which penetrates through the pipe fitting and the first channel and the second channel inside the pipe fitting is formed in the upper middle portion of the pipe fitting, a pushing pillar is movably inserted into the penetrating hole, and a communicating hole isformed in the end close to the middle of the pushing pillar; the negative pressure adsorbing mechanism comprises a flexible gasbag which is communicated with the tail end of the abdominal pressure decompression pipe.

Description

technical field [0001] The invention relates to a medical device, in particular to an improved multi-purpose abdominal puncture device for liver disease departments. Background technique [0002] Paracentesis is a method used to clarify the nature of peritoneal effusion, find out the pathogen, and assist in diagnosis. During paracentesis, a puncture needle is needed for treatment. At present, when there is pressure in the abdominal cavity and there is a lot of fluid, the puncture needle When the skin of the abdomen is broken, the pressure in the abdominal cavity will flow out or spray out through the puncture in a short period of time. At this time, the fluid in the abdominal cavity will also flow out or spray out. Pay attention to, or take adequate protective measures, it is very easy to pollute the working environment and bring infection risks to medical staff; secondly, when the existing puncture needles are in use, doctors usually hold smooth puncture needles The outer ...

[0002] Paracentesis is a method used to clarify the nature of peritoneal effusion, find out the pathogen, and assist in diagnosis. During paracentesis, a puncture needle is needed for treatment. At present, when there is pressure in the abdominal cavity and there is a lot of fluid, the puncture needle When the skin of the abdomen is broken, the pressure in the abdominal cavity will flow out or spray out through the puncture in a short period of time. At this time, the fluid in the abdominal cavity will also flow out or spray out. Pay attention to, or take adequate protective measures, it is very easy to pollute the working environment and bring infection risks to medical staff; secondly, when the existing puncture needles are in use, doctors usually hold smooth puncture needles The outer wall, at this time, is inconvenient for the operation of taking the puncture needle; moreover, when the existing puncture needle uses the syringe to absorb the intraperitoneal fluid after puncturing the skin, it is necessary to hold the puncture needle with one hand to keep the position temporarily out of place. In this case, it not only takes up one of the doctor's hands, but also brings troubles to the doctor's operation, which is one of the reasons why two people are required to cooperate in puncture.
