Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a cervical blocking device after uterine cavity perfusion surgery. Background Art

[0002] In recent years, many uterine cavity diseases, such as uterine cavity adhesions, chronic endometritis, and unexplained endometrial thinness, require intrauterine infusion of drugs for treatment. Usually, after we use a double-lumen tube for drug infusion, in order to prevent the drug from flowing out of the external cervical os, we often have to clamp the patient's cervix with a cervical clamp or let the patient take a head-down position. However, this method only lasts for half an hour at most, which shortens the time the drug stays in the uterine cavity, affects the efficacy of the drug, and causes the patient to need multiple intrauterine infusions, which brings many inconveniences to the patient and increases the patient's medical expenses. Utility Model Content

[0003] The utility model aims to provide a cervical occlusion device after intrauterine perfusion surgery. The cervical occlusion device after intrauterine perfusion surgery adopts a sealing annular plate sleeved on the external os of the cervix. When intrauterine perfusion of drugs is performed, a double-lumen tube can be inserted along the through hole in the center of the sealing annular plate. After the perfusion of drugs is completed, the double-lumen tube is pulled out, and the through hole is sealed by a piston, so that the drugs stay in the uterine cavity for a long time, thereby achieving better treatment effects and facilitating patients and doctors.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cervical blocking device after intrauterine perfusion surgery includes a blocking annular plate, an air bag is pasted on the inner wall of the blocking annular plate, an air inlet pipe is fixed to the end of the air bag facing the blocking annular plate, an air outlet pipe fixed on the air bag is symmetrically arranged with the air inlet pipe, a connecting pipe is connected between the air inlet pipe and the air outlet pipe, a through hole is opened in the middle of the blocking annular plate, a thin film sleeve is fixed inside the through hole, and the through hole and the thin film sleeve are used for inserting a double-lumen tube for intrauterine perfusion.

[0005] Furthermore, an air bag is fixed to the end of the air inlet pipe away from the air bag, and a one-way valve fixed to the air inlet pipe is provided between the air bag and the air bag.

[0006] Furthermore, the air outlet pipe is threadedly connected with a cap at the end away from the air bag.

[0007] Furthermore, the length of the air outlet pipe and the air inlet pipe is 15-20 cm.

[0008] Furthermore, the surface of the through hole is provided with an arc surface.

[0009] Furthermore, a piston is inserted into the film sleeve, a traction rope is fixed to the end of the piston away from the film sleeve, and the end of the traction rope away from the piston is fixed to the sealing annular plate.

[0010] Furthermore, the piston side is provided with convex points, the convex points are integrated with the piston, and there are a plurality of convex points evenly distributed on the piston.

[0011] The beneficial effects of the utility model are:

[0012] 1. A sealing ring plate is set at the external cervical os. When the drug is infused into the uterine cavity, the double-lumen tube can be inserted along the through hole in the center of the sealing ring plate. After the drug infusion is completed, the double-lumen tube is pulled out and the through hole is sealed by the piston, so that the drug stays in the uterine cavity for a long time, achieving better treatment effects and facilitating patients and doctors.

[0013] 2. An air bag is arranged inside the sealing ring plate. By adjusting the size of the air bag, the sealing ring plate can be stably placed on the external cervical os of different sizes, and has wide applicability.

[0014] 3. A connecting pipe is provided between the air inlet pipe and the air outlet pipe to facilitate the removal of the sealing annular plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] Please also refer to Figures 1 to 3 The following will describe in detail the cervical occlusion device after intrauterine perfusion surgery according to an embodiment of the utility model in conjunction with the accompanying drawings. The bracket can be used in conjunction with the lifting structure.

[0021] like Figure 1As shown, the cervical blocking device after intrauterine perfusion surgery includes a blocking annular plate 1, an air bag 2 is pasted on the inner wall of the blocking annular plate 1, an air inlet pipe 3 is fixed to the end of the air bag 2 facing the blocking annular plate 1, an air outlet pipe 4 fixed on the air bag 2 is symmetrically arranged with the air inlet pipe 3, a connecting pipe 5 is connected between the air inlet pipe 3 and the air outlet pipe 4, a through hole 6 is opened in the middle of the blocking annular plate 1, a film sleeve 7 is fixed inside the through hole 6, and the through hole 6 and the film sleeve 7 are used for inserting a double-lumen tube for intrauterine perfusion.

[0022] An airbag 8 is fixed to the end of the air inlet pipe 3 away from the airbag 2, a one-way valve 9 fixed to the air inlet pipe 3 is provided between the airbag 8 and the airbag 2, and a cap 10 is threadedly connected to the end of the air outlet pipe 4 away from the airbag 2.

[0023] As an implementation mode, a piston 12 is inserted into the film sleeve 7, a traction rope 13 is fixed to the end of the piston 12 away from the film sleeve 7, the end of the traction rope 13 away from the piston 12 is fixed to the sealing annular plate 1, and a convex point 14 is provided on the side of the piston 12. The convex point 14 is integrated with the piston 12. There are a plurality of convex points 14, which are evenly distributed on the piston 12. The piston 12 can be inserted into the film sleeve 7. At the same time, the convex points 14 are provided to increase the friction between the piston 12 and the film sleeve 7 to prevent the piston 12 from automatically falling out.

[0024] The sealing annular plate 1 and the piston 12 are both made of medical silicone material.

[0025] Meanwhile, the surface of the through hole 6 is provided with an arc surface 11 .

[0026] During specific use, the lengths of the air inlet pipe 3 and the air outlet pipe 4 are both set to 20 cm, and the connecting pipe 5 is arranged close to the inflation bag 8. The sealing annular plate 1 is placed on the external os of the patient's cervix, and the side of the sealing annular plate 1 wraps the external os of the cervix. According to the different sizes of the external os of the cervix of different patients, the inflation bag 8 is squeezed to introduce air into the air inlet pipe 3. At this time, the cap 10 at the end of the air outlet pipe 4 is not removed, so that the air bag 2 on the inner wall of the sealing annular plate 1 is inflated, and then it hits the side of the external os of the cervix, and the sealing annular plate 1 is fixedly sleeved on the external os of the cervix.

[0027] When intrauterine instillation of drugs is required, such as Figure 3 As shown, the double-lumen tube for perfusion is inserted into the uterine cavity along the through hole 6 on the sealing annular plate 1 to perfuse the drug. In order to facilitate the insertion of the double-lumen tube 15, the entrance of the through hole 6 is set to an arc surface 11. After the perfusion is completed, the double-lumen tube 15 is taken out, and then the piston 12 is inserted into the through hole 6. The side of the piston 12 and the convex point 14 on the side of the piston 12 are in contact with the inner wall of the film sleeve 7 to block the cervical opening, so that the drug can stay in the uterine cavity for a long time, so as to achieve a better therapeutic effect.

[0028] When it is necessary to remove the sealing annular plate 1, open the cap 10 on the air outlet pipe 4, the airbag 2 will deflate automatically, pull the connecting tube 5, and take out the sealing annular plate 1. At the same time, since the length of the air inlet pipe 3 and the air outlet pipe 4 is set to 20 cm, when the sealing annular plate 1 blocks the cervical opening, the connecting tube 5 is located at the patient's vulva, which is convenient for medical staff to remove the sealing annular plate 1.

[0029] The airbag 8, airbag 2 and one-way valve 9 used in this embodiment are all existing conventional products.
