Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-4 The utility model provides the following technical solutions: an anorectal endoscope tube fixing device, including an outer sleeve 1 and a PVC drainage tube 2, and also including: a hard tube 11 and a liquid collecting cover 12.

[0036] Further, by Figure 1 and Figure 2As shown, in this embodiment, the hard tube 11 is located in the outer sleeve 1, one end of the PVC drainage tube 2 is fixedly connected to the hard tube 11 by using a fixing hoop 3, and the liquid collecting cover 12 is fixed to the inner wall of the outer sleeve 1. The end of the hard tube 11 away from the PVC drainage tube 2 is fixedly connected to the liquid collecting cover 12 and communicates with the internal space of the liquid collecting cover 12. A drainage port 13 communicating with the liquid collecting cover 12 is also processed on the outer sleeve 1. After adopting the above scheme, when in use, one end of the PVC drainage tube 2 is fixedly connected to the hard tube 11 by using a fixing hoop 3. The hard tube 11 is fixedly connected and the other end is connected to the negative pressure device. The outer sleeve 1 is inserted into the inside of the patient's anus. The negative pressure device produces negative pressure. The residual liquid is sucked into the hard tube 11 through the drainage port 13 and the liquid collecting cover 12, and finally drawn out from the PVC drainage tube 2. The utility model uses the hard tube 11 and the fixing hoop 3 to fix the PVC drainage tube 2. The fixation is convenient and stable, and the structural form of the outer sleeve 1 can ensure that the residual liquid can reliably enter the PVC drainage tube 2, avoiding the situation where the residual liquid accidentally enters the outer sleeve 1.

[0037] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer sleeve 1, the hard tube 11 and the liquid collecting cover 12 are an integral component formed by injection molding, and have high structural strength.

[0038] It should be noted that the above scheme is only an exemplary scheme of the present invention and is not used to limit the present invention. In actual use, the outer sleeve 1, the hard tube 11 and the liquid collecting cover 12 can also be made of stainless steel and can be reused after disinfection. When the outer sleeve 1, the hard tube 11 and the liquid collecting cover 12 are made of stainless steel, in order to ensure the convenience of production, the outer sleeve 1, the hard tube 11 and the liquid collecting cover 12 are separately processed accessories and fixed and assembled by welding.

[0039] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer sleeve 1 is a hollow frustum-shaped component, and one end of the hard tube 11 extends out of the outer sleeve 1 from the wider end. After adopting the above design, the outer sleeve 1 can be more conveniently inserted into the inside of the patient's anus.

[0040] Optionally, by Figure 1-Figure 3As shown, in this embodiment, the fixing hoop 3 includes: a stainless steel ring 31, a threaded rod 34 and a butterfly nut 35. The two stainless steel rings 31 are distributed at intervals, and a No. 1 fixing block 32 and a No. 2 fixing block 33 are fixed at both ends of the stainless steel ring 31 respectively. One end of the threaded rod 34 is hinged to the No. 2 fixing block 33, and the other end passes through the No. 1 fixing block 32. The butterfly nut 35 is installed on the protruding end of the threaded rod 34 by threaded engagement. After adopting the above scheme, when installing the PVC drainage tube 2, one end of the PVC drainage tube 2 is sleeved on the hard tube 11, and then the stainless steel ring 31 is sleeved at the connection node between the PVC drainage tube 2 and the hard tube 11. Finally, tighten the butterfly nut 35 to make the stainless steel ring 31 tighten the PVC drainage tube 2, so that the stable installation of the PVC drainage tube 2 can be achieved, and the operation is convenient.

[0041] Optionally, by Figure 1-Figure 3 As shown, in this embodiment, the fixing hoop 3 also includes: a perforated mounting ear 331, a fixing block 341 and a mounting shaft 36. The two perforated mounting ears 331 are symmetrically fixed on the second fixing block 33. The fixing block 341 is fixed to the end of the threaded rod 34. The fixing block 341 is rotatably installed on the inner side of the two perforated mounting ears 331 using the mounting shaft 36. After adopting the above scheme, the hinged installation of the threaded rod 34 is realized.

[0042] Preferably, by Figures 1-4 As shown, this embodiment also includes: a positioning ring 112, the positioning ring 112 is fixed to the outer wall of the hard tube 11, and the end face of the positioning ring 112 is a bevel. After adopting the above scheme, the positioning ring 112 is used to limit the stainless steel ring 31, and because the end face of the positioning ring 112 is a bevel, the stainless steel ring 31 squeezes the bevel to generate a component force, further pulling the PVC drainage tube 2, thereby further improving the stability of the installation of the PVC drainage tube 2.

[0043] Preferably, by Figures 1-4 As shown, this embodiment also includes: a necked tube 111, which is fixed to the end of the hard tube 11. After adopting the above solution, when in use, the setting of the necked tube 111 is suitable for PVC drainage tubes 2 of different sizes.

[0044] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer sleeve 1, the hard tube 11 and the liquid collecting cover 12 are all transparent plastic components. After adopting the above solution, the degree of visualization is higher, which is conducive to medical staff to observe the internal situation of the outer sleeve 1.

[0045] Components not described in detail herein are prior art.

[0046] Working principle and use process of the utility model: When using the fixing device of the utility model, one end of the PVC drainage tube 2 is fixedly connected to the hard tube 11 by using the fixing hoop 3, and the other end is connected to the negative pressure device. The outer sleeve 1 is inserted into the inside of the patient's anus. The negative pressure device produces negative pressure, and the residual liquid is sucked into the hard tube 11 through the drainage port 13 and the liquid collection cover 12, and finally drawn out from the PVC drainage tube 2;

[0047] The utility model utilizes the hard tube 11 and the fixing hoop 3 to fix the PVC drainage tube 2, which is convenient and stable. In addition, the structural form of the outer sleeve 1 can ensure that the residual liquid can reliably enter the PVC drainage tube 2, thereby avoiding the situation where the residual liquid accidentally enters the outer sleeve 1 and improving safety.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
