Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of negative pressure drainage device, relates in particular to a kind of negative pressure drainage device for thoracic drainage and thoracentesis.
Background technology
A large amount of hydrothorax or pneumatosis, liquid is extracted in puncture out or gas can alleviate it to the compressing of lung or trunk, breathes or circulatory disturbance to improve.Extract pus during the thoracic cavity empyema out, can alleviate poisoningly, prevent further developing of empyema, and can carry out antibacterial culturing or drug sensitivity test with guiding treatment to pus.Simultaneously, extract hydrothorax out and chemically examine, help clear and definite its character to assist diagnosis and Differential Diagnosis.
Need the assistant to coordinate in the puncture procedure process, to keep constantly the negative pressure in puncture needle.Yet two people's compounding practices and the frequent operating apparatus of changing easily pollute, and have the risk of damage intercostal blood vessel and lung tissue in piercing process.If thoracocentesis device and negative pressure drainage device are used in conjunction with, can greatly reduce operation risk.
Hydrothorax or pneumatosis patient for the spontaneous hydrothorax of part or pneumatosis patient and thoracic injury, operation cause usually need patient's row closed drainage of thoracic cavity operation.For reaching preferably the closed drainage effect and alleviating medical personnel's burden, also need clinically thoracocentesis device and negative pressure drainage device are used in conjunction with.
But, need two medical personnel's compounding practices just can complete when existing negative pressure drainage device and thoracocentesis device are used in conjunction with.For continuing to provide negative pressure, existing negative pressure drainage device also needs medical personnel to observe at any time and adjust in good time the pressure of this device, and this has greatly increased the weight of medical personnel's burden.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of negative pressure drainage device that can greatly alleviate medical personnel's work load is provided.When this negative pressure drainage device coordinated thoracocentesis device to use, the cooperation that need not two medical care personnel just can be completed operation technique easily.
For achieving the above object, technical solution adopted in the utility model is as follows.
A kind of negative pressure drainage device comprises drainage bottle, flexible pipe and syringe, and described drainage bottle top is provided with bottle cap, and described bottle cap is provided with two openings, and two described openings are connected with syringe with flexible pipe respectively, also are provided with air relief valve on described bottle cap.
Further, the opening that is connected with described syringe is provided with flap valve.At opening part, the flap valve structure being set can bleed for the syringe insertion on demand, and when not needing to bleed, this flap valve closes to keep the negative pressure in drainage bottle.
Further, being provided with scale at described flexible pipe indicates.
Further, described syringe comprises syringe needle, syringe, seal rubber plug, push rod and needle handle, and wherein, described syringe needle is arranged at the front end of described syringe and is connected with one of them described opening; Described push rod is positioned at described syringe, and the front end of described push rod is provided with seal rubber plug, and the rear end of described push rod is provided with needle handle; Described seal rubber plug and needle handle are respectively equipped with steam vent, are provided with respectively check valve at the steam vent place of the junction of described syringe needle and described syringe and described seal rubber plug.Described check valve is preferably the flapper-type check valve.
Further, the capacity of syringe is 50-100ml.
The beneficial effects of the utility model are:
Do not need coordinating of two medical personnel when the first, negative pressure drainage device of the present utility model is used in conjunction with thoracocentesis device, just can complete operation technique.
The second, for continuing to provide negative pressure, this negative pressure drainage device does not need medical personnel to observe at any time adjustment, has greatly alleviated medical personnel's burden.
Three, use negative pressure drainage device of the present utility model, do not need syringe from opening bottle cap on extracted after bleeding at every turn, thus can continuous air extraction, be very easy to operation.
