Abstract
The utility model belongs to a medical device, particularly a device for extracting hydrops from the thoracic cavity of patients. The utility model comprises a needle head 7 and a guide tube 6; the end part of the liquid outlet of the guide tube 6 is connected in series with a liquid discharging one-way valve 4 and a liquid sucking one-way valve 5; a syringe joint 1 is arranged on the guide tube 6 between the liquid discharging one-way valve 4 and the liquid sucking one-way valve 5. The device has the advantages of reasonable structure and relatively convenient operation, providing an ideal medical instrument for medical staff.
Description
This utility model belongs to a kind of medical apparatus and instruments, specifically a kind of device that extracts hydrops from the patient thoracic cavity.
Owing to due to the disease, often be easy to generate hydrops in the patient's who has the thoracic cavity, if these hydrops are not discharged from the thoracic cavity in time, it will influence the function of organ pipe in the thoracic cavity and cause other disease, and What is more, and it will jeopardize patient's life.The method of discharging at present this hydrops from the patient thoracic cavity is: with the liquid sucking device of a syringe needle, conduit, syringe composition with the hydrops sucking-off in the thoracic cavity.During use, syringe needle is inserted into the hydrops position in thoracic cavity, with syringe the hydrops in the thoracic cavity is extracted out then, every extraction one syringe hydrops will separate syringe with conduit, the hydrops that extracts in syringe is drained, and then syringe and conduit connect, extract a syringe liquid from the thoracic cavity again, repeatable operation like this is up to the hydrops in the thoracic cavity is extracted out.So intermittently extract the method for hydrops in the thoracic cavity, though can from the thoracic cavity, hydrops be extracted out,, its operation is trouble very, and a people is difficult to finish, and also can bring unnecessary misery for the patient.
It is a kind of rational in infrastructure, easy to operate and do not need to take off repeatedly syringe in the hydrops process drain and extract the dual pathways thoracic-puncture needle of hydrops in extracting the thoracic cavity that the purpose of this utility model is to provide.
This utility model is to realize like this, its adopts traditional syringe needle and conduit, its technical essential is: be in series with an imbibition check valve and a discharge opeing check valve on the conduit between liquid outlet and the syringe needle, be provided with a syringe interface and form between these two check valves.During use, syringe is fixedlyed connected with syringe interface, syringe needle is inserted into the hydrops position in thoracic cavity, from the thoracic cavity, draw hydrops with syringe then, when syringe is drawn hydrops, the discharge opeing closed check valve, and the imbibition one-way valve opens, hydrops enters in the syringe.After the hydrops that extracts some in the syringe, the piston in the pushing syringe, in syringe under the pressure effect of liquid, imbibition closed check valve, and discharge opeing one-way valve opens, the hydrops of extraction is then discharged from liquid outlet.After getting rid of the hydrops in the syringe totally, extract hydrops again, repeat above-mentioned work process, till the hydrops in the thoracic cavity is discharged.
Because this utility model is on the basis of traditional thoracic-puncture needle, a leakage fluid dram and an imbibition check valve and a discharge opeing check valve have been installed, it can just can be extracted the hydrops in the thoracic cavity out so that syringe need not be installed and take off to this liquid sucking device repeatedly, it not only uses very convenient, and structure is also very reasonable.Use this thoracic-puncture needle, can also quicken from the thoracic cavity, to extract the speed of hydrops,, also can alleviate medical personnel's labor intensity simultaneously to alleviate patient's misery.
Fig. 1 is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing this utility model is described in detail.
