The drainage guide device according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, a drainage apparatus according to an embodiment of the present invention includes a drainage bottle 10, a sealing cap 20, a drainage tube 30, and a drainage valve 40.

Specifically, the upper end of the drainage bottle 10 is provided with a negative pressure port 102 and a drainage port 101, the sealing cover 20 covers the drainage port 101, and preferably, the sealing cover 20 is in threaded connection with the drainage port 101, so that the drainage bottle is convenient to detach and reliable in sealing. The negative pressure interface 102 can be connected to a source of negative pressure to create negative pressure within the drainage bottle 10. One end of the drainage tube 30 is inserted into the sealing cover and extends into the drainage port 101, and the other end of the drainage tube 30 is inserted into the drainage position of the body of the patient. The drain valve 40 is disposed at the lower end of the drainage bottle 10 for draining the liquid in the drainage bottle 10.

In a specific use, the other end of the drainage tube 30 can be inserted into a drainage position on the body of a patient, for example, the drainage position is the stomach of the patient, the other end of the drainage tube 30 can be connected to a gastric tube, and is communicated to the stomach of the patient through the gastric tube, while the negative pressure port 102 of the drainage bottle 10 is connected to a negative pressure source, and the liquid at the tail can be drained into the drainage bottle 10 through the drainage tube 30 by the negative pressure in the drainage bottle 10. When the drainage bottle 10 is filled with liquid, the drainage bottle 10 does not need to be detached, the liquid discharge valve 40 at the lower end of the drainage bottle 10 is directly opened, the liquid in the drainage bottle 10 is discharged into a predetermined container, and the drainage bottle 10 after hole discharge can continue drainage.

According to the drainage device provided by the embodiment of the utility model, the drainage valve 40 is arranged on the drainage bottle 10, when the liquid in the drainage bottle 10 is full, the drainage valve 40 can be opened to discharge the liquid in the drainage bottle to a preset container, and the liquid is drained again after the drainage valve 40 is closed, so that the operation is simpler and more convenient, and the burden on a patient is avoided.

In one embodiment of the utility model, the upper end of the drainage bottle 10 is further provided with a negative pressure compensation port 103 and an exhaust interface 104, the drainage device further comprises a spring bottle 50 and a one-way valve 60, the lower end of the spring bottle 50 is provided with a bottle mouth, and the bottle mouth is hermetically connected with the negative pressure compensation port 103; the one-way valve 60 is disposed in the air outlet port 104, and allows air in the drainage bottle 10 to be discharged out of the drainage bottle 10 through the one-way valve 60.

That is, the upper end of the drainage bottle 10 is provided with a negative pressure compensation port 103 and an exhaust port, the spring bottle 50 is connected to the negative pressure compensation port 103, and the exhaust port is provided with a check valve 60. In some cases, the drainage bottle 10 may not have negative pressure or the negative pressure is relatively small, in this case, the spring bottle 50 may be pressed, the gas in the spring bottle 50 is forced to be discharged to the outside through the check valve 60 of the exhaust interface, because the check valve 60 can only allow the gas in the drainage bottle 10 to flow out in a single direction, and the outside gas cannot enter the drainage bottle 10 through the check valve 60, so, after the spring bottle 50 is loosened, the spring bottle 50 recovers to form a suction effect on the drainage bottle 10 in the deformation process, so that a negative pressure is formed in the drainage bottle 10, so that the spring bottle 50 can be utilized to perform negative pressure compensation on the drainage bottle 10, so that when the negative pressure in the drainage bottle 10 is insufficient or does not have negative pressure, the negative pressure compensation can be performed, the negative pressure drainage of the drainage bottle 10 is maintained to be continuous, and the drainage reliability is improved.

Advantageously, the check valve 60 is connected in a pluggable manner in the exhaust interface, so that on one hand, the installation of the check valve 60 is facilitated, and on the other hand, when liquid in the drainage bottle 10 needs to be discharged, the check valve 60 can be pulled out from the exhaust interface to destroy the negative pressure in the drainage bottle 10, so that the liquid in the drainage bottle 10 can be discharged more quickly and smoothly.

In some embodiments of the present invention, the one-way valve 60 comprises a valve housing 601 and an elastic diaphragm 602, wherein the valve housing 601 is connected in a pluggable manner to the air outlet port 104, and the valve housing 601 has an air outlet hole H60 for communicating the drainage bottle 10 with the external atmosphere.

The elastic diaphragm 602 is disposed on the valve housing 601 and closes the vent hole H60, and when the spring bottle 50 is compressed to increase the pressure in the drainage bottle 10, the elastic diaphragm 602 deforms to the side of the external atmosphere to open the vent hole H60.

That is to say, under the condition that does not extrude the elasticity bottle, elasticity diaphragm 602 keeps laminating on valve casing 601 for exhaust hole H60 on valve casing 601 keeps the closed condition, and when compressing the elasticity bottle, the pressure increase in drainage bottle 10 forces elasticity diaphragm 602 to outside atmosphere one side deformation, and then makes exhaust hole H60 open, and the gas in drainage bottle 10 passes through the outside that exhaust hole H60 discharged, so, realized one-way exhaust effect, its simple structure, one-way exhaust effect is reliable and stable.

In one embodiment of the present invention, the valve housing 601 includes a cylindrical portion 601a and a partition portion 601b, the cylindrical portion 601a is connected in the exhaust interface 104 in a pluggable manner; a partition plate 601b is provided in the cylindrical portion 601a to close the cylindrical portion 601a, and the exhaust hole H60 is provided in the partition plate 601 b.

That is to say, the partition 601b is provided with the exhaust hole H60, the elastic diaphragm 602 can be attached to the partition 601b, and further the exhaust hole H60 on the partition 601b is sealed, the structure is simple, the cylindrical portion 601a facilitates the plug-in connection with the exhaust interface 104, and the partition 601b facilitates the arrangement of the exhaust hole H60 and realizes the unidirectional exhaust by matching with the elastic diaphragm 602.

More specifically, the partition 601b is further provided with a central hole, the exhaust hole H60 is multiple, and the exhaust holes H60 are circumferentially arranged at intervals outside the central hole.

The elastic diaphragm 602 includes a sealing cap 602a and a connecting rod, the sealing cap 602a abuts against the outer side surface of the partition 601b and seals the vent hole H60, the upper end of the rod 602b is connected to the center of the sealing cap 602a, the lower end of the rod 602b passes through the central hole and extends downward to form a stopper 602c, and the stopper 602c is stopped at the inner side surface of the partition 601 b.

In this embodiment, the connection rod is inserted into the center hole of the partition 601b to facilitate the installation of the elastic diaphragm 602, and the sealing cap 602a is attached to the partition 601b to achieve a good sealing effect, and when the spring bottle 50 is compressed, the sealing cap 602a can deform to the atmosphere side to reliably open the vent hole H60.

Advantageously, a soft rubber sealing sleeve 61 is sleeved outside the cylindrical portion 601a to seal a gap between the outer surface of the cylindrical portion 601a and the inner surface of the exhaust port 104, so that when the check valve 60 is inserted into the exhaust port 104, the soft rubber sealing sleeve 61 can seal the gap between the outer surface of the cylindrical portion 601a and the inner surface of the exhaust port 104, so that the sealing performance between the check valve 60 and the exhaust port 104 is better.
