Technical Field

[0001] The utility model relates to the technical field of cervical pessaries, in particular to a disposable supporting cervical pessary. Background Art

[0002] Cervical pessary, also known as pessary, is a medical device used to treat uterine prolapse in women. It is made of polyethylene and silicone rubber materials, is non-toxic and non-irritating to human tissue. Ring-type pessary is used for general patients with uterine prolapse. Cervical pessary is generally cylindrical or semi-cylindrical, and is mainly treated by physical methods. Cervical pessary is mainly used to treat habitual miscarriage, premature birth, etc. caused by cervical relaxation. It can effectively prevent uterine prolapse, delay the progression of the disease, and reduce damage to the body. Existing cervical pessary is often made of solid silicone rubber material. When in use, cervical pessary of different sizes is selected according to the degree of prolapse. The traditional cervical pessary is fixed in size and cannot be adjusted according to the actual situation. The support effect is poor. For this reason, we propose a disposable support cervical pessary. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a disposable supporting cervical pessary, which is provided with a fluffy material and a porous water bag barrel inside, wherein a plurality of water bags are placed in the porous water bag barrel. When external pressure is applied, the water bags rupture, and the fluffy material swells when exposed to water, so that the cervical pessary expands and fills the uterine cavity. Water can also be added to the fluffy material or the fluffy material can be extracted by means of a syringe and an external pressure device to change the size of the cervical pessary, thereby effectively solving the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disposable supporting cervical pessary, comprising a central column and an anti-overflow expansion mechanism;

[0005] Central column: a support bracket is provided at its upper end, a support frame is provided at its upper end, a rubber coat is provided at the outer edge of the support frame, and the inside of the support frame and the rubber coat are filled with water-absorbing resin;

[0006] Anti-overflow expansion mechanism: It includes a connecting tube, a guide tube and a guide hole. The connecting tubes are evenly arranged on the outer surface of the central column. A guide tube is provided between the outer ends of the six connecting tubes. The outer surface of the guide tube is provided with evenly distributed guide holes to facilitate uniform water injection and extraction of fluffy materials. Fluffy materials and a porous water bag barrel are provided inside. Several water bags are placed in the porous water bag barrel. When external pressure is applied, the water bag ruptures, and the fluffy material expands when it encounters water, so that the cervical pessary expands and fills the uterine cavity. Water can also be added to the fluffy material or the fluffy material can be extracted by means of a syringe and an external pressure device to change the size of the cervical pessary.

[0007] Furthermore, the anti-overflow expansion mechanism also includes a silicone inner skeleton, which is arranged inside the guide tube. The silicone inner skeleton is distributed in a cross shape to provide a support effect for the guide tube and prevent the guide tube from collapsing and clogging.

[0008] Furthermore, the anti-overflow expansion mechanism also includes a silicone water bag barrel, an overflow hole and a water bag. The silicone water bag barrel is evenly arranged on the outer surface of the guide tube, and the overflow hole is evenly opened on the outer surface of the silicone water bag barrel, providing a basis for the fluffy cervical support.

[0009] Furthermore, the anti-overflow expansion mechanism also includes water bags, and the water bags are all arranged inside the silica gel water bag barrel. The four water bags inside the same silica gel water bag barrel are distributed in a cross shape to better mix with the water-absorbing resin.

[0010] Furthermore, the anti-overflow expansion mechanism also includes an anti-overflow component, which includes a silicone mounting column, a rubber membrane flap and a socket. The silicone mounting column is arranged in the middle of the upper end of the support frame, the rubber membrane flap is evenly arranged inside the silicone mounting column, and the socket is arranged in the middle of the upper end of the silicone mounting column to prevent the internal material of the cervical pessary from overflowing.

[0011] Furthermore, the rubber membrane flaps are all tilted downward, the rubber membrane flaps on the front and rear sides are staggered and overlapped, and the upper end of the inner wall of the socket is chamfered to facilitate the insertion of the needle of the syringe and the external pressure device for suction.

[0012] Furthermore, it also includes an avoidance hole and a bottom pad, wherein the avoidance hole is opened in the middle of the bottom wall of the central column, and the bottom pad is arranged in the middle of the bottom wall of the support frame, and the socket, the avoidance hole and the bottom pad are all vertically adjacent to each other to prevent the needle from piercing the cervical support.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the disposable supporting cervical pessary has the following advantages:

[0014] 1. Squeeze the rubber coat hard. At this time, as the rubber coat is deformed by force, the silicone water bag barrel is also deformed by force and squeezes the water bag at the same time. The water bag is ruptured by force, and the water in the water bag flows out through the overflow hole and mixes with the water-absorbing resin. After the water and the water-absorbing resin are mixed, a gel substance is formed and expands and becomes larger, filling the support frame and the inside of the rubber coat, causing the rubber coat to deform and swell. At this time, the gel substance overflows out through the upper end of the central column. When passing through the rubber membrane flap, the gel substance continuously squeezes the rubber membrane flap upward, making the staggered and superimposed rubber membrane flaps fit tighter and the gap completely disappears, thereby effectively preventing the gel substance from overflowing, which can better support the uterus and prevent uterine prolapse. When external pressure is applied, the water bag ruptures, and the fluffy material swells when it meets water, causing the cervical pessary to expand and fill the uterine cavity.

[0015] 2. When the cervical pessary needs to be enlarged, insert the syringe needle downward from the socket. As the syringe needle moves downward, the needle will push open the staggered and stacked rubber membrane petals until the needle passes through the avoidance hole and contacts the bottom pad. The hard bottom pad prevents the needle from piercing the support frame. At this time, push the syringe down to inject water into the center column. Part of the water enters the diversion tube through the connecting tube, and then overflows from the diversion hole evenly to mix with the water-absorbing resin. The other part of the water directly flows into the support frame through the avoidance hole and mixes with the water-absorbing resin inside the support frame. The formed gel material continues to expand and grow, causing the rubber coat to expand and grow again. When the cervical pessary needs to be reduced, the internal gel material is extracted through the syringe. At this time, the gel material inside the rubber coat becomes less, and the rubber coat shrinks and becomes smaller. Water is added to the fluffy material or the fluffy material is extracted by means of a syringe and an external pressure device to change the size of the cervical pessary.

[0024] The anti-overflow expansion mechanism 4 includes a connecting pipe 41, a guide pipe 42 and a guide hole 43. The connecting pipe 41 is evenly arranged on the outer surface of the central column 1. A guide pipe 42 is provided between the outer ends of the six connecting pipes 41. The outer surface of the guide pipe 42 is provided with evenly distributed guide holes 43, which are convenient for even water injection and extraction of fluffy materials. The anti-overflow expansion mechanism 4 also includes a silicone inner skeleton 44, which is arranged inside the guide pipe 42. The silicone inner skeleton 44 is cross-distributed, which is the guide pipe 4. 2 provides a supporting effect to prevent the drainage tube 42 from collapsing and clogging. The anti-overflow expansion mechanism 4 also includes a silicone water bag barrel 45, an overflow hole 46 and a water bag 47. The silicone water bag barrel 45 is evenly arranged on the outer surface of the drainage tube 42. The overflow hole 46 is evenly opened on the outer surface of the silicone water bag barrel 45 to provide a basis for the fluffy cervical support. The anti-overflow expansion mechanism 4 also includes a water bag 47. The water bag 47 is arranged inside the silicone water bag barrel 45. The water bag 47 is made of PE material, which is easy to squeeze and rupture. It is located in the same silicone water bag The four water bags 47 inside the barrel 45 are cross-distributed to better mix with the water-absorbing resin. The anti-overflow expansion mechanism 4 also includes an anti-overflow component 48, which includes a silicone mounting column 481, a rubber membrane flap 482 and a socket 483. The silicone mounting column 481 is arranged at the middle of the upper end of the support frame 3, and the rubber membrane flap 482 is evenly arranged inside the silicone mounting column 481. The socket 483 is arranged at the middle of the upper end of the silicone mounting column 481 to prevent the internal material of the cervical support from overflowing. The rubber membrane flap 482 They are all tilted downward, and the rubber membrane petals 482 on the front and rear sides are staggered and overlapped with each other. The upper end of the inner wall of the socket 483 is chamfered to facilitate the insertion of the needle of the syringe and the external pressure device for suction. There are fluffy material and a porous water bag barrel inside, and several water bags are placed in the porous water bag barrel. When external pressure is applied, the water bag ruptures, and the fluffy material expands when it encounters water, so that the cervical pessary expands and fills the uterine cavity. The size of the cervical pessary can also be changed by adding water to the fluffy material or extracting the fluffy material through a syringe and an external pressure device.

[0025] The working principle of the disposable supporting cervical pessary provided by the utility model is as follows: when using the cervical pessary, first squeeze the rubber outer coat 5 with force. At this time, as the rubber outer coat 5 is deformed by force, the silicone water bag barrel 45 is also deformed by force and squeezes the water bag 47 at the same time. The water bag 47 is ruptured by force, and the water in the water bag 47 flows out through the overflow hole 46 and mixes with the water-absorbing resin. After the water and the water-absorbing resin are mixed, a gel substance is formed and expands and becomes larger, filling the support frame 3 and the inside of the rubber outer coat 5, causing the rubber outer coat 5 to deform and swell. At this time, the gel substance overflows out through the upper end of the central column 1. When passing through the rubber membrane petal 482, the gel substance continuously squeezes the rubber membrane petal 482 upward, so that the staggered and superimposed rubber membrane petals 482 fit more tightly, and the gap disappears completely, thereby effectively preventing the gel substance from overflowing, and can better support the uterus and prevent uterine prolapse. When the size of the cervical pessary needs to be adjusted, when the cervical pessary needs to be enlarged, the syringe needle is inserted downward from the socket 483. As the needle of the injector moves downward, the needle will push open the staggered and stacked rubber membrane petals 482 until the needle passes through the avoidance hole 6 and contacts the bottom pad 7. The hard bottom pad 7 prevents the needle from piercing the support frame 3. At this time, the syringe is pushed down to inject water into the center column 1. Part of the water enters the guide tube 42 through the connecting tube 41, and then evenly overflows from the guide hole 43 to be fully mixed with the water-absorbing resin. The other part of the water directly flows into the support frame 3 through the avoidance hole 6 and mixes with the water-absorbing resin inside the support frame 3. The formed gel material continues to expand and grow, causing the rubber coat 5 to expand and grow again. When the cervical support needs to be reduced, the internal gel material is extracted through the syringe. At this time, the gel material inside the rubber coat 5 becomes less, and the rubber coat 5 shrinks and becomes smaller. When external pressure is applied, the water bag ruptures, and the fluffy material expands when it meets water, causing the cervical support to expand and fill the uterine cavity. Water can also be added to the fluffy material or the fluffy material can be extracted by a syringe and an external pressure device to change the size of the cervical support.
