Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel volatile medicine-type cervical pessary. Background Art

[0002] Volatile drug-type cervical pessary is a product that can relieve cervical pain and improve the symptoms of cervical diseases. This type of cervical pessary usually adopts volatile drug technology, which allows the drug to evaporate quickly in a gaseous state and achieves a therapeutic effect by directly contacting the cervical tissue. This product has the advantages of fast efficacy, accurate dosage, and easy use;

[0003] Traditional volatile drug-type cervical pessaries fix the drug on the cervical pessary through a carrier, and the drug evaporates rapidly in the body under the influence of body temperature;

[0004] Traditional volatile drug-type cervical pessaries have the following problems: since the drug evaporates rapidly due to the influence of body temperature, it may be difficult to accurately control the release rate and amount of the drug on the cervical tissue. The drug release process is not controllable enough, which reduces the utilization rate of the drug. For this reason, we propose a new type of volatile drug-type cervical pessary. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a new type of volatile drug-type cervical pessary, so that the cervical pessary is safer and more reliable during the treatment process, and can improve the utilization efficiency of the drug, thereby bringing better treatment effects and patient experience, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel volatile drug-type cervical pessary, comprising a rubber ellipsoid, a groove and a mounting groove;

[0007] Rubber ellipsoid: a connection port is provided at the bottom of its outer surface, a sealing groove is provided on the inner wall of the connection port, a conduit is connected to the inner wall of the sealing groove through a rubber sealing ring, and an exhaust pipe and an air intake pipe are plugged into the socket at the bottom of the conduit;

[0008] Grooves: They are all opened on the outer surface of the rubber ellipsoid;

[0009] Installation groove: It is opened at the upper end of the catheter. A connecting mechanism is provided inside the installation groove. The top of the connecting mechanism extends to the inside of the rubber ellipsoid, making the cervical pessary safer and more reliable during the treatment process and improving the utilization efficiency of drugs, thereby bringing better treatment effects and patient experience.

[0010] Furthermore, it also includes valves, which are connected in series to the right ends of the exhaust pipe and the intake pipe to control the flow of gas.

[0011] Furthermore, it also includes a suction cup, which is fixedly connected to the top of the outer surface of the rubber ellipsoid to facilitate the fixing of the cervical support.

[0012] Furthermore, the connecting mechanism includes a guide tube, a slide groove and a supporting mechanism. The guide tube is slidably connected to the upper end of the inner wall of the catheter. Six slide grooves are opened at the upper end of the guide tube. Support mechanisms are provided inside the six slide grooves. The supporting mechanisms are installed in cooperation with the bottom wall of a rubber ellipsoid to ensure smooth movement of the connecting mechanism.

[0013] Furthermore, the support mechanism includes a spring, a sliding column, a support block and a sliding hole. The support blocks are slidably connected to the inner wall of the slide groove. The outer surface of the support block is installed in cooperation with the bottom wall of a rubber ellipsoid. The interior of the support block is provided with a sliding hole. The inner wall of the sliding hole is slidably connected to the sliding column. The end of the sliding column close to the center of the guide tube is fixedly connected to the inner wall of the adjacent slide groove. A spring is fixedly connected between the inner wall of the slide groove and the side of the adjacent support block close to the center of the guide tube. The spring is sleeved on the outer surface of the sliding column to ensure a more stable connection.

[0014] Furthermore, the connecting mechanism also includes an internal threaded swivel, a fixed ring and a rotating groove. There are two fixed rings, and the two fixed rings are respectively fixedly connected to the upper and lower inner walls of the mounting groove. The relative inner sides of the two fixed rings are provided with rotating grooves. An internal threaded swivel is rotatably connected between the rotating grooves. The interior of the internal threaded swivel is threadedly connected to the external thread surface of the guide tube to drive the connecting mechanism.

[0015] Furthermore, the connecting mechanism also includes a rubber sleeve, and the rubber sleeve is fixedly mounted on the outer surface of the internal thread swivel to prevent collision.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the new volatile drug-type cervical pessary has the following advantages:

[0017] 1. By rotating the internal thread swivel and threadedly connecting with the external thread surface of the guide tube, the guide tube is moved upward along the inner wall of the catheter. During the movement, the support block is located on the inner wall of the catheter, and an extrusion force is applied to the support block through the inner wall of the catheter, causing the support block to always be in the slide groove, while keeping the spring in a compressed state. When the top end of the guide tube moves to the inside of the rubber ellipsoid, the spring will rebound and push the support block through the slide hole to rebound along the axis of the slide column until it contacts the bottom wall of the rubber ellipsoid, which can ensure a more stable connection between the catheter and the rubber ellipsoid, thereby enhancing the safety of the treatment process using the cervical pessary and reducing the risk of accidental detachment or displacement of the cervical pessary.

[0018] 2. When using a cervical pessary, first, insert the rubber ellipsoid into the cervix, fix it on the inner wall of the uterus with a suction cup, then connect the air inlet pipe through an external inflation device, and close the valve of the exhaust pipe at the same time. When inflating, the gas is transported to the rubber ellipsoid through the catheter and the guide tube in turn, and pressure is applied to the inside of the rubber ellipsoid under the action of the pressure of the inflation device, so that the filled drugs in the grooves in the rubber ellipsoid are released. Subsequently, due to the action of tension, these drugs are further released onto the cervical tissue, and the pressure on the cervical pessary can be precisely controlled to achieve precise release of drugs, thereby ensuring that the concentration and release rate of drugs in the target area are controllable, which can reduce drug waste and improve drug utilization.
