Abstract
The utility model relates to a medical instrument for taking medium out of a human body, in particular to a thoracic puncture drainage device, comprising a needle body and a negative pressure device. The thoracic puncture drainage device is characterized in that the front end of the needle body is provided with an arc-shaped needle point, and the rear end thereof is provided with an operating handle; the needle body is internally provided with a retaining pipe which is connected with the negative pressure device by a catheter with a control valve; the needle body is provided with metering scales and threads; a positioning disc is connected with the needle body by the threads; and when in use, firstly the position of a fixed disc on the needle body is adjusted according to different puncture parts and different patients, then the needle body is punctured into the body of the patient, then the needle body is pulled out to lead the retaining pipe in the needle body to be retained in the human body and to be positioned and fixed, and then the retaining pipe is connected with the negative pressure device by the catheter which is provided with a control valve. The medical instrument has the advantages of convenient use, simple operation, little wound of the patient, no damage to the blood vessel, nerves and lung tissue among the ribs of the patient, little pain for the patient and good treating effect and the like.
Description
Technical field
This utility model relates to the medical apparatus and instruments that takes out medium in the human body, the thoracic drainage and thoracentesis device that specifically a kind of result of use is good.
Background technology
As everyone knows, thoracentesis device commonly used is that a usefulness rustless steel is made long, thicker needle body, needle body is a hollow, the one end is provided with needle point, the other end is provided with the interface that is connected with syringe or negtive-pressure implement, during use, point of puncture to the patient carries out local anesthesia earlier, needle point with needle body vertically thrusts in patient's the thoracic cavity again, connect syringe or negtive-pressure implement through interface then, intrathoracic gas or liquid are aspirated its weak point: the one, needle point is sharp-pointed, easy damaged patient's intercostal blood vessel, nerve and lung tissue; The 2nd, not easy to operate, depth of needle is wayward, thrusts the back puncture needle and is difficult for fixing, and causes more misery to the patient; The 3rd, this puncture needle can not carry out catheter drainage, must repeated localised puncture aspirate intravital gas of patient or liquid, easily causes the pachynsis pleurae adhesion.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of easy to operate, patient's wound is little, can put and guarantee the thoracic drainage and thoracentesis device that stays.
This utility model can reach by following measure:
A kind of thoracic drainage and thoracentesis device comprises needle body, negtive-pressure implement, it is characterized in that the needle body front end is provided with arcual needle point, and needle rear end is provided with operating grip, is provided with in the needle body to put to stay pipe, puts and stays pipe to be connected with negtive-pressure implement through the conduit of band control valve.
This utility model can be provided with metering scale and screw thread on needle body, positioning disk is connected with needle body through screw thread, can regulate the relative position of positioning disk on needle body by the rotation positioning disk, to regulate the position of fixed disk on needle body with different patients, make more convenient operation according to different sites of puncture.
When this utility model uses, at first regulate the position of fixed disk on needle body with different patients according to different sites of puncture, needle body is thrust in patient's body then, and extract needle body out and make intravital the putting of pin stay pipe to put to stay in the human body and carry out positioning and fixing, to put again and stay pipe to be connected with negtive-pressure implement through conduit, conduit is provided with control valve, the utlity model has easy to use, simple to operate, advantage such as patient's wound is little, blood vessel, nerve and lung tissue, the patient's pain of not damaging patient's intercostal are little, therapeutic effect is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
As shown in drawings, a kind of thoracic drainage and thoracentesis device, comprise needle body 1, negtive-pressure implement 2, needle body 1 is hollow needle body, negtive-pressure implement 2 can adopt syringe to replace, needle body 1 front end that is characterised in that of the present utility model is provided with arcual needle point, needle body 1 rear end is provided with operating grip 3, be provided with in the needle body 1 to put and stay pipe 4, put and stay pipe 4 to be connected with negtive-pressure implement 2 through the conduit 5 of band control valve, in addition, this utility model can be provided with metering scale and screw thread on needle body 1, positioning disk 6 is connected with needle body 1 through screw thread, can regulate the relative position of positioning disk 6 on needle body 1 by rotation positioning disk 6, to regulate the position of fixed disk on needle body with different patients according to different sites of puncture, make more convenient operation, during use, at first regulate the position of fixed disk on needle body with different patients according to different sites of puncture, needle body is thrust in patient's body then, and extract needle body out and make intravital the putting of pin stay pipe to put to stay in the human body and carry out positioning and fixing, to put again and stay pipe to be connected with negtive-pressure implement through conduit, conduit is provided with control valve, the utlity model has easy to use, simple to operate, patient's wound is little, do not damage the blood vessel of patient's intercostal, nerve and lung tissue, patient's pain is little, advantages such as therapeutic effect is good.
