[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1-4 The figure shows the post-feeding system for integrated treatment of medical waste liquid of this utility model, including a waste liquid collection bag (not shown in the figure), a top cover 1 covering the upper end of the waste liquid collection bag, a material release through hole 11 on the top cover 1, a sleeve 2 screwed to the inner wall of the material release through hole 11, a feeding chamber pipe 3 screwed to the inner wall of the sleeve 2, and a sealing cap 4 at the bottom of the feeding chamber pipe 3, which is elastically engaged with the feeding chamber pipe 3.

[0030] like Figure 4 As shown, the waste liquid collection bag is used to collect medical waste liquid. The upper end of the waste liquid collection bag is covered with a top cover 1. The inner wall of the material release through-hole 11 on the top cover 1 has at least one first spiral guide protrusion 12 protruding circumferentially. Preferably, in this embodiment, two first spiral guide protrusions 12 are provided, and the two first spiral guide protrusions 12 are evenly distributed circumferentially along the inner wall of the material release through-hole 11. The top cover 1 is also provided with a liquid inlet 13 and a negative pressure connection port 14. The negative pressure connection port 14 is used to connect to a negative pressure suction device for absorbing negative pressure.

[0031] like Figure 4As shown, the lower part of the outer wall of the sleeve 2 is provided with a first spiral guide groove 21, which is matched with a first spiral guide protrusion 12 for spiral connection between the sleeve 2 and the top cover 1. The inner wall of the sleeve 2 is provided with at least one second spiral guide protrusion 22 along its circumference; preferably, in this embodiment, two second spiral guide protrusions 22 are provided. A first stop plate 23 is provided radially outward at the middle of the outer wall of the sleeve 2, and the bottom of the first stop plate 23 abuts against the top of the top cover 1. The upper part of the outer wall of the sleeve 2 is also provided with multiple reinforcing ribs 24, which are evenly distributed along the circumference of the sleeve 2. The bottom of the reinforcing ribs 24 is fixedly connected to the top of the first stop plate 23, and the side of the reinforcing ribs 24 is fixedly connected to the outer wall of the sleeve 2. The reinforcing ribs 24 are provided to improve the strength and rigidity of the sleeve 2.

[0032] like Figure 5 and Figure 6 As shown, the feeding hopper pipe 3 is a pipe structure with an open bottom. A second spiral guide groove 31 is provided on the lower part of the outer wall of the feeding hopper pipe 3. The second spiral guide groove 31 is configured to cooperate with a second spiral guide protrusion 22, and the spiral direction of the second spiral guide groove 31 is opposite to that of the first spiral guide groove 21. An end plate 32 is provided at the lowest end of the second spiral guide groove 31 to close the end of the second spiral guide groove 31. Notches 33 are provided on the second spiral guide groove 31, located near the end plate 32, and the number of notches 33 is consistent with the number of second spiral guide protrusions 22. A first snap-fit ​​portion 34 protrudes radially outward from the outer wall of the feeding hopper pipe 3, located below the second spiral guide groove 31. An annular sealing groove 35 is also provided on the outer wall of the feeding hopper pipe 3, located above the second spiral guide groove 31. A sealing ring 5 is provided between the feeding hopper pipe 3 and the sleeve 2. The sealing ring 5 is located in the sealing groove 35 and is used to seal the feeding hopper pipe 3 and the sleeve 2. A second stop plate 36 is also provided on the outer wall of the feeding hopper pipe 3. The second stop plate 36 protrudes outward along its radial direction and is located above the sealing groove 35.

[0033] like Figure 3 and Figure 4As shown, the bottom of the feeding hopper pipe 3 is provided with a cap 4, which is elastically engaged with the feeding hopper pipe 3. In this embodiment, both the cap 4 and the feeding hopper pipe 3 are made of materials capable of elastic deformation. Preferably, PP or PE plastic materials with elastic deformation can be used. The top of the cap 4 is provided with an annular groove 41, and the lower part of the feeding hopper pipe 3 is inserted into the annular groove 41. Multiple second engaging parts 42 are protruding on the side wall of the annular groove 41, and the multiple second engaging parts 42 are evenly distributed along the circumference of the annular groove 41. The multiple second engaging parts 42 engage or disengage with the first engaging parts 34. When the cap 4 is pushed, the first engaging part 34 of the feeding hopper pipe 3 pushes the second engaging parts 42 of the cap 4, squeezing and deforming them outward. After further pushing and squeezing deformation, the second engaging parts 42 abut against the first engaging part 34 and are located above the first engaging part 34, and the two are engaged and fixed. When it is necessary to remove the cover 4 from the feeding hopper pipe 3, push the cover 4 in the opposite direction to make it elastically deform again. After the second locking part 42 abuts against the first locking part 34, it moves downward to below it, and the two separate.

[0034] In use, the post-feeding system for integrated treatment of medical waste liquid of this utility model first installs the sealing ring 5 in the sealing groove 35 of the feeding hopper pipe 3. Then, the feeding hopper pipe 3 is aligned with the sleeve 2, and the feeding hopper pipe 3 is rotated so that the two rotate under the cooperation of the second spiral guide groove 31 and the second spiral guide protrusion 22 until the bottom of the second stop plate 36 abuts against the top of the sleeve 2. Next, the coagulant is loaded into the feeding hopper pipe 3, and the cap 4 is pushed up so that the cap 4, after elastic deformation, is snapped and fixed with the feeding hopper pipe 3 through the cooperation of the first snap-fit ​​part 34 and the second snap-fit ​​part 42. At this time, the sleeve, the feeding hopper pipe 3 and the cap 4 are all connected. Next, the sleeve is aligned with the material release through hole 11 of the top cover 1, and the sleeve 2 is rotated so that the two rotate under the cooperation of the first spiral guide groove 21 and the first spiral guide protrusion 12 until the bottom of the first stop plate 23 of the sleeve 2 abuts against the top of the top cover 1.

[0035] When the waste liquid in the waste liquid collection bag needs to be solidified, the feeding tube 3 is rotated counterclockwise. Since the second spiral guide groove 31 and the first spiral guide groove 21 rotate in opposite directions, the sleeve 2 remains stationary when the feeding tube 3 moves upward. As the feeding tube 3 moves the cap 4 upward, when the top of the cap 4 abuts against the bottom of the sleeve 2, the sleeve 2 pushes the cap 4 as the feeding tube 3 continues to move upward, causing the cap 4 to detach from the feeding tube 3. At the same time, the coagulant in the cap 4 and the feeding tube 3 falls freely into the waste liquid collection bag without obstruction. This cap detachment structure does not hinder the flow of coagulant at all, effectively avoiding the problem of incomplete solidification.

[0036] While this utility model discloses preferred embodiments to achieve the above objectives, it is not intended to limit the structural features of this utility model. Anyone skilled in the art should know that any easily conceivable variations or modifications are possible under the technical spirit of this utility model and are covered by the patent claims of this utility model.
