The terms "connected" and "communicating" as used herein, when used in this application, include both direct and indirect connections (or communications), unless expressly stated otherwise.

As shown in fig. 1, the present embodiment provides a negative pressure drainage device, which includes a casing, the casing is communicated with a drainage tube and a drainage tube; wherein, the shell is made of plastic material which can generate deformation; a valve for controlling the opening and closing of the drainage tube is arranged on the drainage tube; the cooperation is installed in the flowing back pipe and is avoided the check valve of flowing back in-process hydrops refluence, can effectively avoid draining the hydrops of drainage in the casing and flow backward. In this embodiment, the export cooperation of fluid-discharge tube is installed and is sealed the stopper, seals the stopper and passes through connecting wire and fluid-discharge tube outer wall connection, and the medical personnel of being convenient for operate from this, still need place alone when avoiding taking off to seal the stopper, and avoids sealing the stopper and easily drops and contaminated and lost problem. In this embodiment, be provided with the clamping part on the casing, be convenient for medical personnel from this with the casing centre gripping on bedside or sick health, avoid the casing to drop and cause the drainage tube to drop.

The drainage tube is the bellows convenient to stretch out and draw back, and the design of bellows makes the drainage tube can set up the length of drainage tube by oneself according to different body parts drainage and different patient health, avoids the drainage tube too short and needs the connection unstability and the nursing degree of difficulty that external connection pipe caused to increase, avoids drainage difficulty and the pipeline winding that the drainage tube overlength caused simultaneously. In this embodiment, the internal cavity of drainage tube is the spiral, has further effectively avoided the hydrops to flow back to the patient in vivo from this.

The shell is provided with at least one supporting surface, and the supporting surface is a part of the outer surface of the shell; the arrangement of the supporting surface ensures that the liquid in the whole shell can not roll randomly when the patient lies in bed or turns over; since the support surface of the housing is not fixed, the support surface can be disposed at any angle of the housing, thereby facilitating the housing to be placed in any orientation. In the embodiment, the number of the supporting surfaces is 2, and the 2 supporting surfaces are vertical to each other, so that when any supporting surface is positioned at a horizontal position, the amount of accumulated liquid can be observed through the graduated scale of the other supporting surface; as shown in fig. 2, the area of the support surface is not greater than the area of the spherical center surface of the housing, making the support surface more flexible in use.

The shell is a sphere, so that the shell has supporting points when a patient turns over or moves, and the shell is prevented from toppling. In this embodiment, the clamping portion, the drainage tube, the drain tube and the exhaust hole are all located on a non-supporting surface of the shell, so that an unstable situation is avoided when the supporting surface is used as a supporting function, and the non-supporting surface is a surface of the outer surface of the shell except the supporting surface.

Be provided with 1 at least scale on the casing, the volume of hydrops is in time looked over to the medical personnel of being convenient for of scale, and then the medical personnel of being convenient for can in time make aassessment and processing to the condition of disease. In this embodiment, be provided with the scale on every holding surface respectively, make medical personnel can the volume of direct observation hydrops after picking up the casing from this, improved the convenient degree of use.

In the embodiment, the shell is provided with the exhaust hole for enabling the shell to be in a negative pressure state, so that the current situation that the shell can be extruded only by opening the outlet of the liquid discharge pipe or the inlet of the drainage pipe is avoided, and the operation is more convenient and faster; the exhaust holes are all matched with and provided with one-way valves, so that the influence of air intake on normal use in a non-exhaust state is avoided. As one of the preferred embodiment, the outside cooperation of exhaust hole is installed and is sealed the lid, and when needs produced the negative pressure, medical personnel manually opened sealed lid, has avoided causing the hydrops in the casing to flow out from the exhaust hole because of the extrusion when daily use from this.

The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
