Detailed Description

The metering drainage box provided by the invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the metering drainage box provided by the present invention comprises a drainage tube 1 and a drainage box body in a transparent box body shape, wherein the internal space of the drainage box body is divided into a metering cavity 2 and a liquid collecting cavity 3 which are respectively arranged at the left and right sides by a longitudinally arranged partition plate, the metering cavity 2 and the liquid collecting cavity 3 are communicated with each other through a first one-way valve 5 arranged on the partition plate, the liquid inlet direction of the first one-way valve 5 is from the metering cavity 2 to the liquid collecting cavity 3, an exhaust cavity 4 is further arranged above the metering cavity 2, the bottom of the exhaust cavity 4 is communicated with the top of the metering cavity 2, the exhaust cavity 4 is communicated with the liquid outlet end of the drainage tube 1 through a second one-way valve 6, the liquid inlet direction of the second one-way valve 6 is from the drainage tube 1 to the exhaust cavity 4, a negative pressure connecting hole 7 is further arranged on the exhaust cavity 4, the liquid collecting cavity 3 is provided with, the metering cavity 2 is provided with scales for displaying the volume of liquid gathered in the metering cavity at a position below the position where the metering cavity is communicated with the first one-way valve 5, the metering cavity further comprises a flushing pipe 9 with a liquid inlet end capable of being selectively opened or closed, and the liquid outlet end of the flushing pipe 9 is communicated between the liquid inlet end and the liquid outlet end of the drainage pipe 1.

When the metering drainage box is used, the liquid inlet end of the drainage tube 1 is used for communicating with the parts of the drainage tubes such as a urinary catheter, a stomach tube, an abdominal cavity tube, a suction head and the like, and the negative pressure connecting hole 7 is used for connecting the suction end of the negative pressure drainage device, so that the exhaust cavity 4 and the drainage tube 1 are in a negative pressure state, and seepage and blood of a patient are adsorbed and collected. The seepage liquid and the blood enter from the liquid inlet end of the drainage tube 1 together with air, enter the exhaust cavity 4 through the second one-way valve 6 to be separated from the gas phase, and the seepage liquid or the blood entering the exhaust cavity 4 enters the metering cavity 2 through the bottom of the exhaust cavity 4, the top of the metering cavity 2 and are collected together. At this time, the medical staff can read the volume of the exudate or blood and the scale display engraved on the measuring cavity 2 by observing the exudate or blood and perform control. In addition, medical staff can calculate the rate of seepage and blood entering the measuring cavity 2 through timing reading, and the measuring cavity is particularly suitable for controlling the bleeding rate of a patient in a surgical operation. When the seepage or blood in the metering cavity 2 reaches a certain amount, medical staff quickly inclines the drainage box body, so that the seepage or blood in the metering cavity 2 enters the liquid collecting cavity 3 through the first one-way valve 5, then the whole drainage box body is reset, the liquid discharge valve 12 is opened, the seepage and the blood are discharged, and the metering collection of the metering cavity 2 is not influenced by the liquid discharge valve 12. In addition, when the liquid in the metering cavity 2 overflows the position communicated with the first one-way valve 5, the liquid can automatically overflow from the first one-way valve 5. When the wound of a patient needs to be cleaned, medical staff can open the liquid inlet end of the flushing pipe 9 and inject water flow from the liquid inlet end of the flushing pipe 9, and the liquid outlet end of the drainage pipe 1 is communicated with the exhaust cavity 4 through the second one-way valve 6, so that the water flow can be sprayed out from the liquid inlet end of the drainage pipe 1, and the wound of the patient can be conveniently cleaned by the medical staff. The drainage box body can be directly placed or can be hooked, in the embodiment, the hook 13 is arranged on the drainage box body, the drainage box body can be suitable for the condition that the drainage box body needs to be hooked, and the switch 14 is arranged between the communication position of the drainage tube 1 and the flushing tube 9 and the liquid outlet end of the drainage tube and used for disconnecting or connecting the two ends of the drainage tube 1.

In the orthopedic surgery, a large amount of fine bone fragments enter the drainage tube 1 along with blood, and the bone fragments are always in a moving state along with the blood in the drainage tube 1; so that the fine bone fragments do not block the drainage tube 1 in normal times. However, in the above embodiment, it is found that, as blood collects in the metering chamber 2, these fine bone fragments will also collect in the metering chamber 2, and due to their own weight, these bone fragments are not easy to enter the liquid collecting chamber 3 along with the inclination of the drainage box body, and when these bone fragments collect to a certain amount, they are easy to cause the blockage of the first one-way valve 5, which affects the normal operation of the metering drainage box. Therefore, in the preferred embodiment, a strainer 8 is disposed at a communication position between the measuring chamber 2 and the exhaust chamber 4 to filter debris such as bone fragments.

In the above embodiment, the liquid inlet end of the flushing pipe 9 is selectively opened or closed, and more specifically, in the present embodiment, the flushing device further includes a screw cap 10 provided with an external thread, an internal thread matching the external thread of the screw cap 10 is provided on an inner wall of the liquid inlet end of the flushing pipe 9, and the screw cap 10 can be screwed into the liquid inlet end of the flushing pipe 9 through the external thread thereof, so as to close the liquid inlet end of the flushing pipe 9. Wherein the screw cap 10 is connected to the flushing pipe 9 by a flexible cord to prevent the screw cap 10 from being lost.

In the above embodiment, the liquid inlet end of the drainage tube 1 is used for communicating with the end portions of the urinary catheter, the stomach tube, the abdominal cavity tube and the suction head, and in order to make the drainage tube 1 suitable for parts with different pore sizes, as a preferred embodiment, the drainage tube further comprises a connector 11 in the shape of a truncated cone, wherein a through hole extending from the smaller end to the larger end of the connector 11 is arranged in the connector, and the through hole is communicated with the liquid inlet end of the drainage tube 1 at the larger end. The drainage tube 1 can be communicated with the end parts of a urinary catheter, a stomach tube, an abdominal cavity tube and a suction head through the connector 11, and the connector 11 in the shape of a cone frustum can be plugged into pipelines with different pore sizes, so that the applicability is improved.

In addition, in the embodiment, the drainage box body is a transparent hard box body made of plastics, and compared with the bag body, the structure can enable medical staff to read the volume of liquid in the metering cavity 2 more accurately. Meanwhile, in order to improve the effect of discharging the permeated liquid or blood entering the liquid collecting chamber 3, in the present embodiment, the drain valve 12 is provided at the bottom of the liquid collecting chamber 3.
