Description

Technical Field

[0001] The present invention relates to the field of production assistance, and in particular to a device for assisting normal delivery and postpartum rehabilitation. Background Art

[0002] Even in today's technologically advanced world, vaginal delivery still poses certain risks to pregnant women. Some pregnant women's vaginas lack sufficient elasticity, making it difficult to fully expand during vaginal delivery, which can easily cause damage. Therefore, starting to gradually strengthen and stretch muscles and tissues three weeks before the expected date of delivery to improve muscle strength and elasticity will help reduce the risk of perineal lacerations and the need for incision, and reduce the difficulty and pain of vaginal delivery for pregnant women. If the perineum is not damaged, muscles and tissues are more likely to recover after delivery. At the same time, pregnancy-related problems such as scars, prolapse, and urinary incontinence can also be avoided. In addition, exercise can reduce labor pain and tension, thereby reducing the need for anesthetics, making the delivery process smoother, accelerating the delivery process, and improving the safety of delivery.

[0003] In addition, during pregnancy and childbirth, pregnant women may suffer from damage and relaxation of the pelvic floor muscles due to the secretion of relaxin, increased pelvic floor load during pregnancy, and episiotomy tearing during normal delivery, which may lead to a series of pelvic floor dysfunction diseases such as urinary incontinence, pelvic organ prolapse, and sexual dysfunction. At the same time, some pregnant women may also suffer from shortened, tense, and high-tension pelvic floor muscles due to reduced exercise, long periods of sitting, and poor posture, which may lead to pelvic floor spasms, pelvic pain, dysuria, frequent urination, and dyspareunia. Therefore, it is particularly important for women to perform pelvic floor muscle repair training after childbirth.

[0004] In addition, to protect women's health, it is necessary to conduct physical examinations on pregnant women before and after delivery, especially to test women's vaginal secretions. However, when testing vaginal secretions, the existing sampling method usually requires medical staff to use cotton swabs to scrape women's vaginal secretions. This method not only requires medical staff to operate, but is also difficult for women to be examined to complete by themselves. In addition, due to the lack of effective external protection of the cotton swab, if the cotton swab is in contact with the outside air for a long time during the sampling process, or the sampling part of the cotton swab accidentally touches the outer wall of the test tube or the operator's skin, it may cause the cotton swab to be contaminated, thereby affecting the accuracy of the test results. Summary of the invention

[0005] In order to overcome the deficiency in the prior art that samples are easily contaminated when examining vaginal secretions, the present invention provides a device for assisting normal delivery and postpartum rehabilitation. The device can not only perform vaginal dilation training for pregnant women before delivery, pre-dilate the vagina during normal delivery, and perform pelvic floor muscle repair training after delivery, but can also assist medical staff or pregnant women themselves to collect vaginal secretions more conveniently and safely, thereby improving sample quality and providing a more reliable basis for women's health examinations.

DETAILED DESCRIPTION

[0018] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0019] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the present invention is further described below in conjunction with the drawings and embodiments.

[0020] As attached Figure 1-8 The device for assisting normal delivery and postpartum rehabilitation shown in the figure comprises a silicone balloon 1, a main air pipe 11 and a manual pump 12 which are connected in sequence, and a control valve 111 and a pressure display 112 are provided on the main air pipe 11. A film 3 is provided on the outer cover of the silicone balloon 1, a core column 2 is provided in the silicone balloon 1, a first air cavity 21 extending axially is provided in the core column 2, a first piston column 211 is sealed and slidably connected in the first air cavity 21, and a clamping block 212 is connected to the first piston column 211. A cotton swab 2121 is detachably connected to the clamping block 212, and the cotton swab 2121 is located on the outer side of the film 3 and cooperates with the clamping block 212 to clamp the film 3. The first air cavity 21 is connected to a pressurized balloon 22 through the bronchus, and the pressurized balloon 22 can move the first piston column 211 by changing the air pressure of the first air cavity 21, so that the cotton swab 2121 on the clamping block 212 extends from the front end of the core column 2 or retracts into the core column 2.

[0021] Among them, the film 3 covers the outside of the silicone balloon 1 to protect the silicone balloon 1 from external contamination. The first air cavity 21 and the first piston column 211 in the core column 2 are moved by the air pressure change of the pressurized ball balloon 22, so that the cotton swab 2121 on the clamping block 212 can be extended or retracted, thereby simplifying the operation process and reducing the risk of the cotton swab 2121 being contaminated during the sampling process. Through the air pressure adjustment of the pressurized ball balloon 22, the movement of the first piston column 211 realizes the automatic extension and retraction of the cotton swab 2121, avoiding the risk of contamination caused by manual operation, and also improving the convenience and accuracy of operation. Furthermore, the detachable connection design between the clamping block 212 and the cotton swab 2121 makes the replacement of the cotton swab 2121 more convenient and improves the practicality of the device. As a preferred embodiment, the clamping block 212 can be fixed to the cotton swab 2121 by a threaded connection or a snap connection to ensure the firmness of the connection and the ease of operation.

[0022] The silicone balloon 1 is used for pelvic floor muscle training and stretching the perineum and pelvic floor muscles. Specifically, it can be made of medical-grade silicone material and is used to sense the pressure of the pelvic floor muscles and apply pressure to the pelvic floor. The manual pump 12 is used to inflate the silicone balloon 1, the pressure display 112 is used to monitor the air pressure in the silicone balloon 1 in real time, and the control valve 111 is used to control the discharge of the gas in the silicone balloon 1. These features cooperate with each other to achieve accurate detection and control of the inflation pressure of the silicone balloon 1, thereby better promoting the effect of postpartum rehabilitation.

[0023] In some embodiments, an axially extending storage chamber 23 is provided in the core column 2, and the clamping block 212 is slidably and rotatably connected to the storage chamber 23. The side wall of the storage chamber 23 is provided with a linear guide rail 231, and the linear guide rail 231 is used to limit the rotation of the clamping block 212; an axially extending guide chamber 2122 is provided in the clamping block 212, and a transmission block 2123 is slidably and rotatably connected in the guide chamber 2122, and a spiral guide rail 2124 is provided on the side wall of the guide chamber 2122, and a guide pin slidably connected to the spiral guide rail 2124 is provided on the transmission block 2123, and the first piston column 211 is integrally connected to the transmission block 2123 through a linkage rod 2111; the length of the linear guide rail 231 is less than the linear stroke of the clamping block 212, and when the cotton swab 2121 on the clamping block 212 extends from the front end of the core column 2, the clamping block 212 disengages from the linear guide rail 231.

[0024] The arrangement of the receiving chamber 23 enables the clamping block 212 to slide and rotate in the core column 2, while the arrangement of the linear guide rail 231 limits the rotation of the clamping block 212, ensuring its stability during the sliding process. The cooperation of the guide chamber 2122 and the spiral guide rail 2124 enables the transmission block 2123 to slide and rotate accurately in the clamping block 212, and the sliding connection between the guide pin and the spiral guide rail 2124 further enhances the motion control of the transmission block 2123. The first piston column 211 is connected to the transmission block 2123 through the linkage rod 2111, and drives the transmission block 2123 to move when the first piston column 211 moves. When the cotton swab 2121 on the clamping block 212 extends from the front end of the core column 2, the clamping block 212 moves along the storage cavity. When the clamping block 212 moves to a position that is separated from the linear guide rail 231, the clamping block 212 can rotate under the action of the spiral guide rail 2124, so that the cotton swab 2121 can collect high-quality samples, providing a more reliable basis for vaginal health monitoring during pregnancy and prenatal diagnosis.

[0025] In some embodiments, a support ring 24 is provided at the front end of the core column 2 , and an elastic ring 241 is sleeved on the support ring 24 . The elastic ring 241 has a tendency to shrink.

[0026] The support ring 24 can provide a stable support platform for the elastic ring 241, so that the elastic ring 241 can be stretched and maintained in a state with a contraction tendency during the sampling process. The elastic ring 241 can be made of silicone or other elastic materials, which not only have good elasticity, but also can withstand certain stretching and compression, and can also be sterilized for medical use.

[0027] In some embodiments, an axially extending second air cavity 25 is provided in the core column 2, and a second piston column 251 is sealed and slidably connected in the second air cavity 25; the first air cavity 21 is provided in the second piston column 251 and is connected to the second air cavity 25, and the pressurized balloon 22 can move the second piston column 251 by changing the air pressure in the second air cavity 25, so that the second piston column 251 extends from the front end of the core column 2 or retracts into the core column 2; a push-off structure is provided at the front end of the second piston column 251, and in the process of the second piston column 251 extending from the front end of the core column 2, the push-off structure can push the elastic ring 241 away from the support ring 24, so that the elastic ring 241 is sleeved on the second piston column 251 under the action of its own elastic contraction force; in the process of the second piston column 251 retracting into the core column 2, the support ring 24 can push the elastic ring 241 away from the second piston column 251, so that the elastic ring 241 restrains the film 3 under the action of its own elastic contraction force.

[0028] In some embodiments, the push-off structure includes a first mounting hole 2511 opened on the outer wall of the second piston column 251, a push-off block 2512 is slidably connected in the first mounting hole 2511, a first elastic member 2513 is connected between the push-off block 2512 and the first mounting hole 2511, and an avoidance groove 2514 is opened on the support ring 24 for the push-off block 2512 to pass through, and the avoidance groove 2514 extends into the core column 2. A second mounting hole 252 may be provided on the side wall of the second air cavity 25, in which a locking pin 2521 is slidably connected, a second elastic member 2522 is connected between the locking pin 2521 and the second mounting hole 252, a locking hole 2523 that fits with the locking pin 2521 is provided on the outer wall of the second piston column 251, in which a push column 2524 is slidably connected; when the cotton swab 2121 on the clamping block 212 extends from the front end of the core column 2, the locking pin 2521 is embedded in the locking hole 2523, thereby limiting the retraction of the second piston column 251 into the core column 2; when the cotton swab 2121 on the clamping block 212 is retracted into the core column 2, the first piston column 211 withdraws the locking pin 2521 from the locking hole 2523 through the push column 2524, thereby releasing the restriction on the retraction of the second piston column 251 into the core column 2. Furthermore, after the second piston column 251 is retracted into the core column 2, the elastic ring 241 loses its support. The shrinking tendency of the elastic ring 241 can be used in conjunction with the film 3 to effectively protect the cotton swab 2121 after the sampling process is completed. The elastic ring 241 can shrink and tightly wrap the cotton swab 2121 in the film 3 to prevent the cotton swab 2121 from contacting the external air, thereby reducing the risk of sample contamination.

[0029] A first mounting hole 2511 is provided on the outer wall of the second piston column 251, a push-off block 2512 is slidably connected in the first mounting hole 2511, a first elastic member is connected between the push-off block 2512 and the first mounting hole 2511, and an escape groove 2514 is provided on the support ring 24 for the push-off block 2512 to pass through, and the escape groove 2514 extends into the core column 2. The design of the first mounting hole 2511 enables the push-off block 2512 to slide on the outer wall of the second piston column 251, and the first elastic member 2513 provides the elastic force required by the push-off block 2512. The escape groove 2514 on the support ring 24 ensures that the push-off block 2512 can pass through smoothly and act on the elastic ring 241. When the second piston column 251 is extended, the push-off block 2512 pushes the elastic ring 241 away from the support ring 24 through the elastic force of the first elastic member 2513 , and when the second piston column 251 is retracted, the elastic ring 241 will be separated from the second piston column 251 , thereby achieving the binding of the elastic ring 241 .

[0030] In some embodiments, a second mounting hole 252 is provided on the side wall of the second air cavity 25, a locking pin 2521 is slidably connected in the second mounting hole 252, a second elastic member 2522 is connected between the locking pin 2521 and the second mounting hole 252, a locking hole 2523 that fits with the locking pin 2521 is provided on the outer wall of the second piston column 251, and a push column 2524 is slidably connected in the locking hole 2523; when the cotton swab 2121 on the clamping block 212 extends from the front end of the core column 2, the locking pin 2521 is embedded in the locking hole 2523, thereby limiting the retraction of the second piston column 251 into the core column 2; when the cotton swab 2121 on the clamping block 212 is retracted into the core column 2, the first piston column 211 withdraws the locking pin 2521 from the locking hole 2523 through the push column 2524, thereby releasing the restriction on the retraction of the second piston column 251 into the core column 2.

[0031] The second mounting hole 252 is designed so that the locking pin 2521 can slide therein, and the second elastic member 2522 provides an elastic force so that the locking pin 2521 can remain in a certain position when not acted upon by external forces. The opening of the locking hole 2523 matches the shape of the locking pin 2521, ensuring that the locking pin 2521 can be accurately embedded in the locking hole 2523. The design of the push column 2524 is to enable the locking pin 2521 to be pushed out of the locking hole 2523 through the action of the first piston column 211 when the cotton swab 2121 is retracted into the core column 2, thereby releasing the restriction on the second piston column 251.

[0032] When the cotton swab 2121 extends from the front end of the stem 2, the locking pin 2521 will automatically fit into the locking hole 2523 due to the action of the second elastic member 2522, thereby preventing the second piston column 251 from being retracted, thereby ensuring the stability of the device. When the cotton swab 2121 is retracted into the stem 2, the first piston column 211 pushes the locking pin 2521 out of the locking hole 2523 through the action of the push column 2524, so that the second piston column 251 can be freely retracted into the stem 2, thereby restoring the normal function of the device. Thus, by opening the second mounting hole 252 on the side wall of the second air cavity 25, and slidingly connecting the locking pin 2521 therein, the second elastic member 2522 is connected between the locking pin 2521 and the second mounting hole 252, and the outer wall of the second piston column 251 is provided with a locking hole 2523 that matches the locking pin 2521, and the push column 2524 is slidably connected in the locking hole 2523. When the cotton swab 2121 on the clamping block 212 extends from the front end of the stem 2, the locking pin 2521 is embedded in the locking hole 2523, restricting the second piston column 251 from retracting into the stem 2; when the cotton swab 2121 on the clamping block 212 is retracted into the stem 2, the first piston column 211 withdraws the locking pin 2521 from the locking hole 2523 through the push pin 2524, thereby releasing the restriction on the retraction of the second piston column 251 into the stem 2. This design ensures that when the cotton swab 2121 is extended, the second piston column 251 will not retract, thereby maintaining the stability of the device.

[0033] In some embodiments, the outer wall of the support ring 24 is designed to be conical, and the end close to the stem 2 is a pointed end. The outer wall of the support ring 24 is designed to be conical, which helps to better adapt to and support the elastic ring 241 during the use of the device, and at the same time, it can be smoothly separated from the second piston column 251 after the second piston column 251 is retracted into the stem 2, thereby maintaining the stability of the device. Among them, only water-based lubricants can be used to lubricate the film 3.

[0034] 1. Use the present embodiment to execute the training plan by following the steps below: First, open the control valve 111, squeeze out the air in the silicone balloon 1 by hand, and then close the control valve 111 to keep the silicone balloon 1 in a deflated shape. Next, wrap the film 3 around the outside of the silicone balloon 1, and lubricate the outside of the film 3 appropriately.

[0035] When it is necessary to strengthen the pelvic floor muscles during pregnancy or after childbirth: Place about half (peanut-shaped) of the silicone balloon 1 wrapped with a film 3 in the vagina and slide it up and down gently to feel the elasticity of the perineum area. Observe the pointer number on the pressure display 112, and then perform Kegel training for pelvic floor muscle contraction. It specifically includes the training of rapid contraction of the pelvic floor type II muscle fibers followed by immediate relaxation (relaxation lasts for 3 seconds), and contraction-maintaining (maintaining tightening of the pelvic floor muscles for 5 to 10 seconds)-relaxation (relaxation lasts for 5 to 10 seconds) of the pelvic floor type I muscle fibers. During the training, continuously observe the changes in the pointer numbers on the pressure display 112 (i.e., the pressure difference) to evaluate the performance of the pelvic floor muscles. It should be noted that when contracting the pelvic floor muscles, try to pull the silicone balloon 1 upwards, and by clamping the silicone balloon 1 and pulling the silicone balloon 1 upwards, a coordinated movement of pelvic floor muscle contraction is formed. Repeat the above actions for 10 minutes.

[0036] When the perineum needs to be stretched: place the silicone balloon 1 about half of which is wrapped with the film 3 in the vagina, and then slowly inflate the silicone balloon 1 to gradually expand the silicone balloon 1. The size of the inflated silicone balloon 1 in the body can be adjusted by referring to the changes in the pointer numbers on the pressure display 112. Leave the inflated silicone balloon 1 in the vagina for about 10 minutes. This stretching helps to gently expand the soft tissues such as the mucous membranes and muscles of the perineum area and birth canal. In addition, the size of the inflated silicone balloon 1 can be gradually increased from one training session to the next, but it must always be kept within the personal comfort range. If you feel uncomfortable, you can reduce the size of the silicone balloon 1 at any time by operating the control valve 111.

[0037] When you need to simulate the childbirth experience: After completing the above-mentioned perineum stretching, relax the pelvic floor muscles, imagine that the silicone balloon 1 is the baby's head, and slowly expel it from the vagina. In the process of expelling the silicone balloon 1, pregnant women can experience the feeling of childbirth, which helps to relieve anxiety and fear about natural childbirth, while further increasing tissue elasticity and reducing the possibility of episiotomy and tearing. It should be noted that it is recommended that each operation time does not exceed 20 minutes, and at the same time, ensure that the diameter of the silicone balloon 1 does not exceed 8-10 cm.

[0038] 2. Use the device to sample vaginal secretions by following the steps below: During the installation of the film 3, the inflated balloon is first pressed to make the clamping block 212 protrude from the stem 2, and then the film 3 is covered on the silicone balloon 1. Finally, the cotton swab 2121 is inserted into the clamping block 212 and the elastic ring 241 is placed on the support ring 24 to fix the film 3. After the inflated balloon is released, the cotton swab 2121 enters the storage cavity 23 under the action of negative pressure. At this time, the front end of the device covered with the film 3 can be placed in the patient's vagina to start sampling vaginal secretions.

[0039] By pressing the inflatable balloon 22 again, the first piston column 211 moves forward under the action of air pressure, and at the same time drives the clamping block 212 to move forward in the storage chamber 23. As the clamping block 212 moves forward, it will disengage from the linear guide rail 231. At this time, the cotton swab 2121 on the clamping block 212 is in the patient's vagina. Since the clamping block 212 is free from the constraint of the linear guide rail 231, under the action of the guide pin of the transmission block 2123 and the spiral guide rail 2124, the clamping block 212 and the cotton swab 2121 rotate together, thereby completing high-quality sampling of vaginal secretions.

[0040] Then continue to press the inflatable balloon 22. Since the first piston column 211 is at the maximum stroke position, the air pressure will push the second piston column 251 forward. As the second piston column 251 moves to the corresponding position of the avoidance groove 2514 on the core column 2, the push-off block 2512 is lifted upward under the push of the first elastic member 2513, so as to contact the elastic ring 241 and push the elastic ring 241 to the outer wall of the second piston column 251. At the same time, the locking pin 2521 on the core column 2 falls into the locking hole 2523 of the second piston column 251 under the action of the second elastic member 2522, locking the second piston column 251.

[0041] Finally, release the pressurized balloon 22. Under the action of negative pressure, the first piston column 211 returns to the position with the smallest stroke. At this time, the cotton swab 2121 is in the storage chamber 23. In the process of the first piston column 211 returning to the position with the smallest stroke, the cotton swab 2121 will first rotate, which will apply a certain rotation to the film 3 to further improve the airtightness performance; secondly, the first piston column 211 will push up the push column 2524 to make the locking pin 2521 leave the locking hole 2523, thereby unlocking the second piston column 251. Similarly, under the action of negative pressure, the second piston column 251 retracts into the core column 2 and returns to the position with the smallest stroke. When the second piston column 251 retracts into the core column 2, the elastic ring 241 loses its support. The shrinkage trend of the elastic ring 241 can be used in conjunction with the film 3 to effectively protect the cotton swab 2121 after the sampling process is completed. The elastic ring 241 can shrink and tightly wrap the cotton swab 2121 in the film 3 to prevent the cotton swab 2121 from contacting the external air, thereby reducing the risk of sample contamination.
