Description

Technical Field

[0001] The invention belongs to the technical field of A61F6 / 08 pessaries, and in particular relates to an adjustable pessary which is easy to take and put. Background Art

[0002] As people's requirements for quality of life increase, women need a multifunctional device that can prevent urine leakage and exercise the vaginal pelvic floor muscles when running, climbing, laughing, etc. increase negative pressure. Some patients have turned to pessaries for help and have achieved certain clinical results. Therefore, pessaries are no longer just used to treat uterine prolapse, but are an auxiliary device that may be widely used. However, the removal and placement of existing pessaries is very inconvenient, and often requires the help of others to complete. In addition, the removal and placement are easy to force the vaginal opening, resulting in the adverse consequences of loose vaginal opening. It is also necessary to try multiple pessaries of different sizes to get the right model for use, and the patient experience is very poor. When wearing a pessary, the patient needs to lie flat with his legs bent and slightly separated. The patient or the person who places it uses two fingers of the left hand to separate the labia, and the two fingers of the right hand to pinch the pessary flat or even twist it up to reduce its area. It can only be inserted into the vagina after being forced across the smaller vaginal opening to reach the wider vaginal cervical vault to achieve the purpose of lifting and improving prolapse symptoms. The material of the pessary on the market is generally medical silicone. In order to achieve the purpose of holding up, it has a certain hardness and elasticity. It is necessary to use the strength of two fingers of the right hand to achieve the purpose of squeezing and forcing it across the small vaginal opening. It is very difficult for a female medical staff with weak arms and fingers. It is even more difficult for the patient to operate it by himself. Often, after struggling for a long time, he fails to insert it as he wishes and has to give up. The same disadvantages exist when removing it.

[0003] Chinese patent document CN 207462218U discloses an easy-to-place and easy-to-remove pessary, including a pessary body, a protrusion is provided at the bottom of the pessary body, and the end of the protrusion has an enlarged protrusion, so that the pessary can be taken in and out by a special clamp that cooperates with the protrusion. The pessary can be taken in and out by the special clamp. The protrusion and the clamp are preferably connected by magnetism, but if the magnetism is too weak and the vagina is curved, the clamp is easy to be detached from the protrusion when pulled out. If the magnetism is too strong, after the pessary is pushed to the specified position, the clamp is not easy to be separated from the pessary. Chinese patent document CN 111616832A also discloses an easy-to-use pessary assembly for obstetrics and gynecology, including a pessary for supporting prolapsed pelvic organs and a taking forceps for taking the pessary, wherein the top of the taking forceps is connected to the bottom of the pessary through an electromagnet, and the top of the taking forceps and the bottom of the pessary attract each other after power is turned on, and the top of the taking forceps and the bottom of the pessary do not generate attraction after power is turned off. However, regardless of the adverse effects of the current on the inner wall of the vagina after power is turned on, the attraction of the electromagnet may not be enough to pull the pessary out of the curved and narrow vagina.

[0004] Although the above two existing technologies can achieve the technical effect of convenient placement and removal of the pessary to a certain extent, after using the clamp or forceps, the fingers of the medical staff can no longer sensitively sense the direction and resistance of the inner wall of the vagina, which can easily cause damage to the inner wall of the vagina when the pessary is pushed into or pulled out of the vagina.

[0005] In order to solve the above technical problems, the applicant proposed a solution of an adjustable pessary, which is described in detail in Chinese patent document CN112370232A. It includes an umbrella-shaped support body and a support body telescopic mechanism, the support body telescopic mechanism includes a pillar and a sliding part located on the pillar, a plurality of connecting rods are arranged between the sliding part and the umbrella-shaped support body, the connecting rod is located outside the pillar, and the sliding part moves along the pillar to realize the extension and folding of the umbrella-shaped support body. When in use, the support body is pushed to the designated position in the vagina by pushing the pillar with fingers, and then the connecting rod is pushed and pressed by fingers, so that the connecting rod unfolds the umbrella-shaped support body in the process of dragging the sliding part upward. When the pessary needs to be withdrawn from the vagina, the connecting rod is hooked with one finger, and the pessary can be pulled outward, and at the same time, the sliding part will slide down to fold the umbrella-shaped support body. This solution provides convenience for placing the pessary, but because the sliding part is an elastic ring, when pushing the connecting rod upward, it is generally necessary to push and press along the pillar several times to unfold the umbrella-shaped support body in a balanced manner. On the other hand, when you hook your fingers on the connecting rod and pull the pessary out, it is still easy to cause damage to the inner wall of the vagina. Summary of the invention

[0006] The object of the present invention is to overcome the deficiencies of the prior art and to provide an adjustable pessary that is easy to take and place, which can easily and quickly unfold or fold the umbrella-shaped support body, and can keep the pessary in a folded state when placed or taken out, thereby facilitating taking and placing.

[0007] In order to achieve the above object, the technical solution of the present invention is as follows:

[0008] The invention discloses an adjustable pessary which is easy to take and put, comprising an umbrella-shaped support body, a support body push rod, and a support body telescopic part. The umbrella-shaped support body is fixed to the top of the support body push rod and can be extended and retracted by the support body telescopic part. The support body telescopic part comprises a sliding sleeve and a telescopic bracket. The sliding sleeve slides down along the support body push rod to drive the telescopic bracket to contract and retract the umbrella-shaped support body. The support body telescopic part is equipped with an elastic component to enable the umbrella-shaped support body to be automatically extended. The support body push rod is provided with a switch part for automatically extending the umbrella-shaped support body and positioning the sliding sleeve after the umbrella-shaped support body is retracted.

[0009] The invention concept of the present invention is: the spring-opening principle of the self-opening umbrella is applied to the pessary, the umbrella-shaped support body is equivalent to the umbrella surface of the umbrella, the support body push rod is equivalent to the umbrella handle of the umbrella, and the support body telescopic part is equivalent to the umbrella rib of the umbrella. When placing the pessary, the user pushes the support body push rod with fingers to push the umbrella-shaped support body to the uterine mouth. During this process, the umbrella-shaped support body is in a folded state, so it is easier to push the umbrella-shaped support body to a designated position. Afterwards, the switch is started, and the sliding sleeve moves up along the support body push rod under the action of the elastic component, driving the support body telescopic part to open and the umbrella-shaped support body to unfold, and the surrounding of the umbrella-shaped support body is easier to be stuck in the posterior fornix of the vagina. When the pessary needs to be withdrawn from the vagina, the finger is inserted into the vagina to press the support body telescopic part located under the umbrella-shaped support body, and the support body telescopic part contracts to make the sliding sleeve move down along the support body push rod until it meets the switch and is positioned. At this time, the umbrella-shaped support body returns to the folded state, which is convenient to pull it out with fingers. Compared with the technical solution described in Chinese patent document CN112370232A, the sliding sleeve can move up and down along the support body push rod in a relatively balanced manner, and can realize the simple and rapid unfolding or folding of the umbrella-shaped support body more smoothly, conveniently and harmlessly.

[0010] As an improvement, the switch has a starter mechanism located at the bottom of the support body push rod. To prevent the switch from opening when entering and exiting the vagina, the starter mechanism is located at the bottom of the support body push rod to prevent the vaginal wall from pressing it and opening it.

[0011] As an improvement, the lower part of the support body push rod is hollow, and the switch member is located in the hollow interior of the support body push rod.

[0012] As an improvement, the switch member is an elastic fastener, and the starting mechanism is two starting rods extending beyond the bottom of the support body push rod, and the starting rods are respectively connected to two sides of the elastic fastener.

[0013] As an improvement, a pull ring is provided at the bottom of the support body push rod, and the lower part of the starting mechanism is located inside the pull ring, thereby reducing the starting mechanism from being accidentally triggered.

[0014] As an improvement, the telescopic brackets are evenly arranged in at least 4 groups along the sliding sleeve, so that the telescopic brackets can unfold or fold the umbrella-shaped support body in a relatively balanced manner.

[0015] As an improvement, the elastic component is arranged in the telescopic bracket, and the elastic component includes a compression spring. According to the technical solution described in the Chinese patent document CN112370232A, during daily activities of the human body, the umbrella-shaped support body may be compressed and the elastic ring may slide down, and the pessary may easily fall out of the vagina. After adopting this solution, due to the presence of the compression spring, when the umbrella-shaped support body may be compressed, the compression spring can offset its deformation, and the restoring force of the compression spring can make the umbrella-shaped support body open to its original state. Therefore, the optimized pessary is not easy to fall out of the vagina due to daily life activities.

[0016] As an improvement, the telescopic bracket includes a first connecting rod, a second connecting rod, and a third connecting rod which are hinged in sequence, the two ends of the first connecting rod are respectively connected to the middle part of the second connecting rod and the sliding sleeve, the third connecting rod is connected between the end of the second connecting rod and the umbrella-shaped support body, and the compression spring is located between the second connecting rod and the third connecting rod.

[0017] As an improvement, the elastic component includes a torsion spring, which is located at the hinge between the first connecting rod and the second connecting rod and at the hinge between the second connecting rod and the third connecting rod.

[0018] As an improvement, an adjustable limiter is provided on the upper part of the support push rod, and the movement of the limiter can adjust the expansion degree of the umbrella-shaped support. By pre-positioning the limiter, the position of the highest point of the sliding sleeve can be limited, thereby limiting the expansion degree of the umbrella-shaped support, so that the umbrella-shaped support is suitable for the patient's own physiological structure.

[0019] In summary, the present invention has the advantages of simple structure, practical functions and obvious effects. It can realize the easy and quick expansion or folding of the umbrella-shaped support body to facilitate the placement and removal of the pessary. It can also adjust the expansion degree of the umbrella-shaped support body according to the patient's physiological structure. It is not easy to slip out of the vagina due to deformation during use.

The umbrella-shaped support body 10 is bowl-shaped, with an opening facing upward, and is fixed to the top of the support body push rod 20. The support body push rod 20 has a wide top, and the top is arc-shaped and concave to adapt to the bottom shape of the umbrella-shaped support body 10. The umbrella-shaped support body 10 can be extended and retracted by the support body telescopic member. The support body telescopic member is equipped with an elastic component 40 so that the umbrella-shaped support body 10 can be automatically unfolded. The support body push rod 20 is provided with a switch member 50 for automatically unfolding the umbrella-shaped support body 10 and positioning the sliding sleeve 31 after the umbrella-shaped support body 10 is retracted. The support body push rod 20 is also provided with a sheet-shaped body at a position below the switch member 50. The sheet-shaped body provides a fulcrum for the finger to push or hook. When the pessary is pushed into or hooked out of the vagina, the sheet-shaped body is convenient for the finger to operate. An adjustable stopper 70 is provided on the upper part of the support body push rod 20, and the movement of the stopper 70 can adjust the degree of expansion of the umbrella-shaped support body 10. The stopper 70 is a nut, and a thread for the nut to move is provided on the upper part of the support body push rod 20. The closer the nut is to the top of the support body push rod 20, the greater the expansion degree of the umbrella-shaped support body 10.

[0029] like Figure 4 As shown, the lower part of the support push rod 20 is hollow and can accommodate the switch member 50. The switch member 50 is an elastic fastener. Figure 5 As shown, the switch member 50 has a starter mechanism 51, which is two starter rods extending beyond the bottom of the support body push rod 20, and the starter rods are respectively connected to the two sides of the elastic fastener. The two starter rods are pressed toward each other to release the sliding sleeve 31 and move it upward. A pull ring 60 is provided at the bottom of the support body push rod 20, and the lower part of the starter mechanism 51 is located inside the pull ring 60. The starter mechanism 51 is located at the bottom of the support body push rod 20 as a whole.

[0030] like Figures 1 to 3 As shown, the telescopic part of the support body includes a sliding sleeve 31 and a telescopic bracket 32, and the telescopic bracket 32 ​​is evenly arranged in 8 groups around the sliding sleeve 31. Each group of telescopic brackets 32 includes a first connecting rod 321, a second connecting rod 322, and a third connecting rod 323 that are hinged in sequence. The two ends of the first connecting rod 321 are respectively connected to the middle part of the second connecting rod 322 and the sliding sleeve 31, and the third connecting rod 323 is connected between the end of the second connecting rod 321 and the umbrella-shaped support body 10. The compression spring of the elastic component 40 is located between the second connecting rod 322 and the third connecting rod 323. The elastic component 40 also includes a torsion spring, which is located at the hinge of the first connecting rod 321 and the second connecting rod 322 and the hinge of the second connecting rod 322 and the third connecting rod 323. The cross-sectional view of the sliding sleeve 31 is shown in FIG. Figure 6As shown, when the notch at the sliding sleeve 31 intersects with the switch member 50, the positioning of the sliding sleeve 31 can be achieved. The sliding sleeve 31 slides down along the support body push rod 20 to drive the telescopic bracket 32 ​​to contract and the umbrella-shaped support body 10 to fold, and the sliding sleeve 31 slides up along the support body push rod 20 to drive the telescopic bracket 32 ​​to open and the umbrella-shaped support body 10 to unfold.

[0031] All parts of the pessary, except the elastic component 40, can be made of silicone, which is an ideal medical engineering material with adjustable hardness and softness. The elastic components 40 are all located on the inner side of the telescopic bracket 32. During the process of taking and placing the pessary, the elastic components 40 are not easy to directly contact the inner wall of the vagina.
