As a further optimization of the utility model, the axis of the front joint coincides with the axis of the housing, and the axis of the rear joint is parallel to the axis of the front joint.
As a further optimized scheme of the utility model, a second baffle is arranged at a position in the second cavity, which is communicated with the rear joint, a plurality of second through holes are distributed on the second baffle, the second top plate is conical, and the top of the second top plate is arranged at one side close to the front joint.
As a further optimization scheme of the utility model, a limiting cylinder is arranged in the second cavity, a spring is arranged in the limiting cylinder, the spring is fixedly connected with the floating ball, the inner diameter of the limiting cylinder is larger than the diameter of the floating ball, and the pressure of the body fluid on the floating ball is larger than the pressure of the spring on the floating ball.
The utility model has the beneficial effects that:
1) the utility model has small volume and convenient carrying, and can effectively prevent the reverse flow of drainage fluid and avoid complications such as postoperative infection of patients;
2) the interface external diameter is standard size, can be with the seamless butt joint of standard drainage tube, avoids the liquid seepage.
Drawings
FIG. 1 is a schematic structural view of embodiment 1 of the present invention;
FIG. 2 is a schematic sectional view of embodiment 2 of the present invention;
in the figure: 1. a housing; 11. a front joint; 12. a rear joint; 13. a first cavity; 14. a second cavity; 2. a first baffle plate; 21. a first through hole; 22. an arc-shaped portion; 3. a floating ball; 4. a second baffle; 41. A second through hole; 5. a limiting cylinder; 6. a spring.
Detailed Description
The present application will now be described in further detail with reference to the drawings, it being noted that the following detailed description is given by way of illustration only, and should not be construed as limiting the scope of the present application, since numerous insubstantial modifications and adaptations of the present application will become apparent to those skilled in the art based upon the foregoing description.
Example 1
As shown in fig. 1, the anti-reflux drainage connector is made of medical plastic materials, and comprises a shell 1, a front connector 11 arranged on one side of the shell 1 and a rear connector 12 arranged on the other side of the shell 1, wherein the front connector 11 and the rear connector 12 are of standard sizes of medical connectors, so that the anti-reflux drainage connector can be in seamless butt joint with a standard drainage tube to avoid liquid leakage;
meanwhile, a first baffle 2 is arranged in the shell 1, the first baffle 2 divides the shell 1 into a first cavity 13 close to the front joint 11 and a second cavity 14 close to the rear joint 12, a floating ball 3 is arranged in the second cavity 14, a first through hole 21 is arranged in the middle of the first baffle 2, the inner diameter of the first through hole 21 is smaller than the diameter of the floating ball 3, and an arc-shaped part 22 is arranged on the surface of the first baffle 2, which is in contact with the floating ball 3;
when the drainage device is used, the connector is arranged behind the drainage end of a patient, a drainage bag pipeline is connected downwards, and when drainage liquid enters the first cavity from the front connector, the drainage liquid can smoothly enter the second cavity through the shell and then flows out through the rear connector; when the height of the drainage bag is equal to or higher than the drainage plane of the patient, the floating ball in the shell is just blocked by the baffle plate to block the first through hole, at the moment, the liquid can not flow back, and the joint plays a role of a one-way valve;
furthermore, the axis of the front joint 11 is overlapped with the axis of the shell 1, but the axis of the rear joint 12 is parallel to the axis of the front joint 11, namely the axis of the rear joint is not on the same axis as the axis of the front joint, so that the influence of the floating ball blocking the rear joint on liquid discharge is avoided;
further, in order to better avoid the influence of the floating ball on the liquid outlet of the rear joint, a second baffle 4 is arranged in the second cavity 14 and communicated with the rear joint 12, a plurality of second through holes 41 are distributed on the second baffle 4, the second baffle 4 is conical, and the top of the second baffle 4 is arranged on one side close to the front joint 11; no matter what position the joint is, once the floating ball is close to the rear joint, the second baffle plate can block the reliability of the robbing structure.
Example 2
As shown in fig. 2, although the floating ball is matched with the first baffle in embodiment 1 to play a certain role in preventing backflow, when the height of the drainage bag is equal to or higher than the drainage plane of a patient, the floating ball in the housing floats in the housing, which easily causes that the baffle cannot block the first through hole, therefore, a limiting cylinder 5 is arranged in the second cavity 14, a spring 6 is arranged in the limiting cylinder 5, the spring 6 is fixedly connected with the floating ball 3, the inner diameter of the limiting cylinder 5 is larger than the diameter of the floating ball 3, and the pressure of the spring 6 on the floating ball 3 is smaller than the pressure of body fluid on the floating ball 3; therefore, the reliability of the structure can be effectively improved through the limiting effect of the spring and the limiting cylinder on the floating ball.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
