Abstract
The utility model provides a disposable continuous liquid extractor, which comprises a drainage tube and a draft tube, wherein a liquid containing chamber is arranged between the drainage tube and the draft tube, the liquid containing chamber is connected with an inflating ball through a hose, the joints of the drainage tube as well as the draft tube and the liquid containing chamber are both provided with check valves, and when negative pressure is formed in the liquid containing chamber, the check valve at the drainage tube is opened, and the check valve at the draft tube is closed; when positive pressure is formed in the liquid containing chamber, the check valve of the drainage tube is closed, and the check valve of the draft tube is opened; and the purpose of continuous liquid extraction can be realized through repeatedly extruding air in the inflating ball. Compared with the prior art, the disposable continuous liquid extractor disclosed by the utility model has the characteristics of reasonable design and the like, is convenient to use, can be used for completely sucking hydrops in the thoracic cavity of a patient and ensures smooth treatment.
Description
Technical field
This utility model relates to the technical field of medical instruments of cardiothoracic surgery special use, a kind of specifically disposable continuous liquid extracting device.
Background technology
When doing cardiac thoracic surgery, have a lot of hydrops and blood in the patient thoracic cavity sometimes at present, be unfavorable for that the doctor performs an operation, existing liquid extracting device often is not a continuous sucking, can waste a lot of quality time, especially to some critical patients' operation, time is life, this liquid extracting device can disposablely be finished when liquid more after a little while, but when liquid more for a long time, need to extract repeatedly repeatedly, complex operation, lose time, medical personnel's labor intensity is big, and the intrathoracic hydrops suction of patient is not thorough etc.
The utility model content
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of disposable continuous liquid extracting device is provided.
The technical solution of the utility model realizes in the following manner: this disposable continuous liquid extracting device, its structure comprises drainage tube, mozzle, it is characterized in that, between drainage tube and mozzle, be provided with the Sheng sap cavity, containing ins succession on the sap cavity inflates ball, is provided with check valve in the junction of drainage tube, mozzle and Sheng sap cavity; Wherein check valve is a needle-valve.And the conducting when containing the sap cavity negative pressure of the check valve at drainage tube place, the conducting when containing the sap cavity malleation of the check valve at mozzle place.
The beneficial effect that this utility model is compared with prior art produced is: 1, disposable continuous liquid extracting device of the present utility model have simple in structure, easy to use, characteristics such as be skillfully constructed, the gun type design is easy to take and operate, can hold aspirator on the other hand, on the other hand ball is inflated in extruding, the disposable suction operation of finishing; 2, open simultaneously by check valve is non-, guaranteed the continued operation of liquid extracting device, guarantee carrying out smoothly of treatment.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Labelling in the accompanying drawing is represented respectively: 1, drainage tube, 2, check valve, 3, contain sap cavity, 4, flexible pipe, 5, inflate ball, 6, check valve, 7, mozzle, 8, catcher.
The specific embodiment
Below in conjunction with accompanying drawing disposable continuous liquid extracting device of the present utility model is done following detailed description the in detail.
As shown in Figure 1, disposable continuous liquid extracting device, its structure comprises drainage tube 1, mozzle 7, be provided with between drainage tube 1, the mozzle 7 and contain sap cavity 3, containing sap cavity 3 is connecting by flexible pipe 4 and is inflating ball 5, be provided with check valve 2 and check valve 6 at drainage tube 1, mozzle 7 with the junction of containing sap cavity 3, mozzle 7 is connecting catcher 8.During use, at first drainage tube 1 is placed on the hydrops place, will inflates the air crowded empty of ball 5 with hands, unclamp and inflate ball 5, will form negative pressure in containing sap cavity 3, at this moment, check valve 6 is closed, and check valve 2 is opened, and hydrops is sucked in the Sheng sap cavity 3; Press then and inflate ball 5, air in it is extruded, at this moment containing in the sap cavity 3 is malleation, and check valve 6 is opened, and check valve 2 is closed, and hydrops will flow in the catchers 8 through mozzle 7, so repeatedly extruding inflate ball 5 will the intrathoracic hydrops of continuous sucking.The disposable suction operation of finishing hydrops, time saving and energy saving.
Claims (2)
1. disposable continuous liquid extracting device, comprise drainage tube, mozzle, it is characterized in that, be provided with the Sheng sap cavity between described drainage tube and the mozzle, in succession by flexible pipe on this Sheng sap cavity and inflate ball, at drainage tube and contain between the sap cavity and be equipped with check valve between mozzle and the Sheng sap cavity.
