Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the implementation of the utility model will be further described in detail below with reference to the examples and drawings.

As shown in Figure 1-7, the simple and convenient new negative pressure drainage bottle provided by the utility model includes a bottle body 1, a top cover 4 and an external connection tube 5, and a negative pressure rubber plug 2 is fixedly connected to one side of the top of the bottle body 1 , the middle position of the top of the bottle body 1 is fixedly connected with a threaded interface 3, the outer wall of the threaded interface 3 is threadedly connected with a top cover 4, the top of the outer wall of the top cover 4 is equipped with an external connecting pipe 5, and one side of the top cover 4 is fixedly connected There is an auxiliary structure 7, the auxiliary structure 7 includes a valve interface 701, a threaded cap 702 and a sealing plug 703, the valve interface 701 is arranged on one side of the top cover 4, and one side of the valve interface 701 outer wall is threadedly connected with a threaded cap 702, the threaded cap One side of the inside of 702 is fixedly connected with a sealing plug 703 , the valve interface 701 and the inside of the top cover 4 are perpendicular to each other, and the valve interface 701 and the inside of the sealing plug 703 are in a mosaic structure.

The working principle of the simple and convenient new negative pressure drainage bottle is that compared with the traditional negative pressure drainage bottle, the utility model has a top cover 4 threaded on the outer wall of the threaded interface 3, and is used under the cooperation of the threaded cap 702 and the anti-backflow structure 6. The flow direction of the negative pressure drainage bottle in the bottle body 1 can be adjusted inside the top cover 4. When the external connecting pipe 5 is blocked in the extrusion groove 602, the threaded cap 702 is unscrewed to make the valve interface 701 pass through, and then the internal volume of the bottle body 1 The liquid can be dumped and cleaned outwards. When the threaded cap 702 is tightened, the sealing plug 703 blocks the inside of the valve interface 701 to cause blockage, and the external connecting pipe 5 is moved to the inside of the diversion groove 603, so that the negative pressure drainage bottle can pass through the external The connecting tube 5 attracts hemostatic cotton, subcutaneous tissue and blood clots in the upper drainage tube, so that the negative pressure drainage bottle is more convenient during operation and minimizes contact with the outside world.

The outer wall of the outer connecting pipe 5 is penetrated with an anti-backflow structure 6. The anti-backflow structure 6 includes a clamping plate 601, an extrusion groove 602, a diversion groove 603 and an anti-skid bump 604. The clamping plate 601 runs through the outer wall of the outer connecting pipe 5. One side of the clamping plate 601 is provided with an extrusion groove 602, and the other side of the clamping plate 601 is provided with a diversion groove 603, and one side of the two ends of the extrusion groove 602 is fixedly connected with an anti-slip protrusion 604, and the anti-slip protrusion The blocks 604 are distributed symmetrically with respect to the horizontal centerline of the extrusion groove 602 , and there is a sliding structure between the diversion groove 603 and the inside of the external connecting pipe 5 .

When the negative pressure drainage bottle is in use, in order to prevent backflow of the fluid inside the bottle body 1, some anti-backflow parts will be installed in the traditional negative pressure drainage bottle. Squeeze to cause blockage, and then prevent the negative pressure drainage bottle from effusion backflow phenomenon. When the external connection tube 5 is moved to the diversion groove 603, the external connection tube 5 will be opened so that the external connection tube 5 can be smoothly diverted, and in order to prevent the external connection tube When the 5 is in the extrusion groove 602, there is an accidental sliding and detachment. Therefore, anti-skid bumps 604 are provided on both ends of the extrusion groove 602, so that the anti-skid bumps 604 can limit the position of the external tube 5, so as to prevent the extrusion groove 602 from Slippage occurs when the external connecting pipe 5 is squeezed and blocked.

The inside of the bottom of the top cover 4 is fixedly connected with an airtight structure 8. The airtight structure 8 includes a sealing ring 801, a support ring 802 and an alcohol cotton pad 803. The bottom of the sealing ring 801 is fixedly connected to the inner bottom of the top cover 4. The outer wall is provided with a support ring 802, the top of the support ring 802 is fixedly connected with an alcohol cotton pad 803, the sealing ring 801 is in the same vertical plane as the threaded interface 3, and the cross-sectional area of the inner diameter of the support ring 802 is greater than the cross-section of the outer diameter of the threaded interface 3 area.

When the negative pressure drainage bottle is installed, in order to prevent leakage between the threaded interface 3 and the top cover 4, a sealing ring 801 is arranged inside the bottom of the top cover 4, so that when the threaded interface 3 and the top cover 4 are installed The sealing ring 801 is in close contact with the top of the threaded interface 3, so that the gap between the threaded interface 3 and the top cover 4 is blocked, so as to improve the airtightness of the negative pressure drainage bottle. The end will squeeze the alcohol cotton pad 803, because the alcohol inside the alcohol cotton pad 803 has a certain bactericidal effect, so that the external bacteria will not be mixed into the negative pressure drainage bottle through the connection between the threaded interface 3 and the top cover 4 to cause infection. In this way, the use airtightness of the negative pressure drainage bottle is greatly improved.

Although the embodiments disclosed in the present utility model are as above, the content described is only an embodiment adopted for the convenience of understanding the present utility model, and is not intended to limit the present utility model. Anyone skilled in the technical field to which the utility model belongs can make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in the utility model, but the patent of the utility model The scope of protection must still be based on the scope defined in the appended claims.
