Abstract
The utility model relates to a medical appliance and in particular to a negative pressure absorbing water sealing bottle which is suitable for the enclosed type water spreading treatment for the patient needing closed drainage in spontaneous pneumothorax or traumatic pneumothorax or for the patient needing the closed drainage in the end of thoracic operation. The medical appliance comprises a liquid collecting cavity and a pressure regulating cavity; wherein the liquid collecting cavity is respectively connected with a chest cavity and the pressure regulating cavity through a pipeline; the pressure regulating cavity is connected with a negative pressure generator through the pipeline; the utility model is characterized in that the pressure regulating cavity is provided with a through pipe communicated with the atmosphere and the inner cavity; the through pipe is provided with a pressure regulating valve. The utility model mainly solves the technical problem that the prior device can regulate negative pressure only under the conditions that a through hole is provided on the pressure regulating cavity and the negative pressure regulating generator is cooperatively regulated; the utility model not only has simple operation but also is in favor of improving the accuracy of the regulation.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, the vacuum suction water-sealed drainage bottle that the patient that particularly being applicable to needs closed drainage behind spontaneous pneumothorax, traumatic pneumothorax and the thoracic surgery is used.
Background technology:
The present vacuum suction water-sealed drainage bottle that uses, mostly being greatly of employing comprise that diversion chamber (fluid collection chamber), negative pressure chamber (water seal chamber) and negative pressure adjust the structure of chamber (pressure regulating cavity) composition.A kind of enclosed vacuum suction water-sealed drainage bottle that is used for the splanchnocoel drain is disclosed as Chinese utility model patent description (CN2294059Y).It comprises hydrops bottle and water seal adjust blood pressure bottle and bottle cap thereof, drainage tube, communicating pipe, there is a drain to connect post on the hydrops bottle cap and connection connects post, have on the water seal adjust blood pressure bottle cap that water sealing (sealing water) pipe connects post, liquid feeding connects post and adjust blood pressure connects post, the water sealing (sealing water) pipe and the adjustable pipe that connect the post lower end all need be inserted into a bottle bottom seal, and adjust blood pressure connects and is connected to a negative pressure ball on the post.Negative pressure value in this negative pressure ball scalable negative pressure chamber, and be not subjected to the restriction of regional condition.It overcome existing three Room water-sealed drainage bottle volumes excessive, make complicatedly, and the patient can not regulate the drawback of negative pressure value when using water-sealed drainage bottle in moving process, is specially adapted to basic hospital.
But, the adjust blood pressure of above-mentioned water-sealed drainage bottle mainly is to establish a through hole of opening a bit in advance by connecing on pressure regulating cavity, and default certain pressure P b, after connecting negative pressure generator, behind the generation Pa pressure, will in the thoracic cavity, produce negative pressure Pc, the value of this Pc is exactly the pressure differential of Pa and Pb, because at this moment, the pressure of Pb is a fixed value, therefore, the adjusting of negative pressure can only realize by the pressure Pa of regulating the negative pressure generator generation, is unfavorable for so very much small pressure adjusting.And by opening the mode of through hole, the precision that also can't keep-up pressure and regulate.
The utility model content:
The purpose of this utility model is to provide the adjustable thoracic cavity of a kind of negative pressure closed drain water-sealed drainage bottle, mainly solve existing apparatus and could regulate the technical problem of negative pressure by on pressure regulating cavity, opening some through holes and fit adjustment negative pressure generator, not single operation is simple, and helps improving the precision of adjusting.
For solving the problems of the technologies described above, this utility model is achieved in that
The closed drain water-sealed drainage bottle in the thoracic cavity that a kind of negative pressure is adjustable, comprise fluid collection chamber, pressure regulating cavity, this fluid collection chamber connects thoracic cavity and pressure regulating cavity respectively by pipeline, this pressure regulating cavity connects negative pressure generator by pipeline, it is characterized in that: this pressure regulating cavity has a siphunculus that is communicated with atmosphere and intracavity, and this siphunculus is provided with a pressure-regulating valve.
The closed drain water-sealed drainage bottle in the thoracic cavity that described negative pressure is adjustable is characterized in that: this water-sealed drainage bottle also has a U-shaped pipe and measures the chamber.
By said structure, the utlity model has following advantage:
Pressure regulating cavity of the present utility model has a siphunculus that is communicated with atmosphere and intracavity, and this siphunculus is provided with a pressure-regulating valve, by said structure, can cooperate negative pressure generator to regulate negative pressure jointly, helps the accurate adjusting of device.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure:
The 1-fluid collection chamber;
The 2-pressure regulating cavity;
The 3-negative pressure generator;
The 4-siphunculus;
The 5-pressure-regulating valve.
The specific embodiment:
See also Fig. 1, it is the structural representation of the adjustable closed drain water-sealed drainage bottle in thoracic cavity of a kind of negative pressure of this utility model.As shown in the figure: it comprises fluid collection chamber 1, pressure regulating cavity 2, this fluid collection chamber 1 connects thoracic cavity and pressure regulating cavity 2 respectively by pipeline, this pressure regulating cavity 2 connects negative pressure generator 3 by pipeline, it is characterized in that: this pressure regulating cavity 2 has a siphunculus 4 that is communicated with atmosphere and intracavity, and this siphunculus 4 is provided with a pressure-regulating valve 5.This water-sealed drainage bottle also has a U-shaped pipe and measures the chamber, can be used for accurately measuring negative pressure.
During use, utilize control valve 5 to cooperate negative pressure generator 3 to regulate negative pressure jointly, so just help to increase degree of regulation.
When control valve cuts out fully, Pc=Pa;
When control valve was opened, Pc was the pressure differential between Pa and the Pb.
Above-described is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present utility model.
