Abstract
Description
Technical Field
[0001] The invention relates to the technical field of labor-inducing balloons, and in particular to a convenient labor-inducing balloon for obstetrics and gynecology. Background Art
[0002] The labor induction balloon is a medical device that is mainly used to promote cervical ripening and induce labor. The labor induction balloon usually consists of two inflated balloons and two injection tubes. The two injection tubes are connected to the two balloons and inserted into the cervical opening through a catheter. After the balloon is inflated, it will exert gentle pressure on the cervix, simulating the pressure of the fetal head on the cervix, causing the cervix to gradually expand and soften. After the cervix is mechanically stimulated, it will release bioactive substances such as prostaglandins, which can further promote cervical ripening, thereby initiating uterine contractions and thus promoting the start of the delivery process.
[0003] When placing the labor-inducing balloon in the body, various auxiliary equipment and tools are used to ensure the safety and effectiveness of the operation, including vaginal dilators, whose main function is to dilate the vagina to facilitate the insertion of the catheter; however, when using the vaginal dilator, the vaginal dilator will over-stretch the patient's vaginal opening, which will cause strong discomfort to the patient, especially when the cervix is not fully mature; some patients will also feel pain (especially when the dilator is opened), and even cause bleeding in the patient, which is not conducive to the placement of the labor-inducing balloon. At the same time, in the process of placing the labor-inducing balloon, various auxiliary equipment and tools will be placed, which makes the overall operation process cumbersome, resulting in low efficiency of labor-inducing balloon placement, and too many operations will also increase the risk of incorrect operation.

DETAILED DESCRIPTION
[0021] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.
[0022] Research has found that during the placement of the labor-inducing balloon, in order to ensure the accuracy and effectiveness of the operation, a vaginal dilator is usually used to open the patient's vagina to facilitate the doctor's insertion of the catheter into the vagina. However, during the process of opening the dilator, the patient will feel some discomfort, pain, and even bleeding, which will affect the placement of the labor-inducing balloon and is not conducive to the smooth progress of the labor-inducing operation.
[0023] A convenient induced labor balloon for obstetrics and gynecology, please refer to Figure 1-Figure 6 , including: a cover plate 1, the cover plate 1 is fixedly connected with a first tube 2, and the side of the first tube 2 away from the cover plate 1 is fixedly connected with a second tube 3; a support shell 4 is fixedly connected to the side of the second tube 3 away from the first tube 2, and the support shell 4 is filled with lubricating oil; a first connecting shell 5 is arranged in the first tube 2 and passes through the cover plate 1; a second connecting shell 6 is arranged in the support shell 4; a first balloon 7 is slidably connected to the second connecting shell 6, and the second connecting shell 6 is fixedly connected with a second balloon 8, and the second balloon 8 is located on the side of the first balloon 7 away from the cover plate 1; an extrusion mechanism is arranged on the support shell 4, which is used to push the lubricating oil in the support shell 4; a connecting adjustment mechanism is arranged on the second connecting shell 6, which is used to control the shape of the first balloon 7 and the second balloon 8 and adjust the position of the first balloon 7, and the side of the support shell 4 away from the second tube 3 is arranged in a truncated cone shape.
[0024] In the above scheme, a method is mainly proposed in which the labor-inducing balloon can be placed in the patient's body without using a vaginal dilator, and the placement of the catheter and the labor-inducing balloon is more convenient; the first tube 2, the second tube 3 and the support shell 4 jointly play a supporting role, so as to open the patient's vagina, so as to facilitate the placement of the labor-inducing balloon and the catheter to the designated position; the lubricating oil is used to lubricate the patient's vagina, reduce the resistance of the vaginal wall, and make the placement of the support shell 4 smoother; in this embodiment, the first connecting shell 5 and the second connecting shell 6 are connected to each other, so that the first balloon 7 and the second balloon 8 enter the patient's body by pushing the first connecting shell 5; the lower side of the support shell 4 is truncated cone-shaped, so as to facilitate the support shell 4 to enter the patient's body.
[0025] Workflow: When using the device to place the first balloon 7 and the second balloon 8 in the body, the doctor holds the first tube 2 and inserts the support shell 4 into the vagina. During this process, the doctor operates the squeezing mechanism to squeeze out the lubricating oil of the support shell 4 to facilitate the insertion of the support shell 4. The support shell 4 drives the first balloon 7 and the second balloon 8 therein to enter the patient's vagina together, reducing the doctor's operating steps and improving the placement efficiency of the induction balloon. At the same time, the support shell 4 is used to expand the patient's vagina, reducing the area of the patient's vagina to expand, reducing the stimulation to the patient's vagina, thereby reducing the harm to the patient and reducing the probability of discomfort and bleeding in the patient.
[0026] After moving the supporting shell 4 to the designated position, the doctor pushes the first connecting shell 5 and the second connecting shell 6 to insert the second balloon 8 into the cervix and the first balloon 7 into the vagina. Then, physiological saline is pumped into the second balloon 8 through the connecting adjustment mechanism to expand the second balloon 8 and apply squeezing force to the cervix. Physiological saline is pumped into the first balloon 7 through the connecting adjustment mechanism and the position of the first balloon 7 is adjusted to expand the first balloon 7 and move it to a suitable position to apply gentle pressure to the vagina.
[0027] After the first balloon 7 and the second balloon 8 are inflated, the doctor observes the patient and monitors the changes in the patient's cervix and uterine contractions. If the cervix reaches a certain degree of expansion and softening, or the uterine contractions begin to become regular, the doctor removes the device from the patient's body, thereby terminating the use of the device.
[0028] Further disclosure based on the above scheme: Please refer to Figure 2-Figure 5 The extrusion mechanism includes: an extrusion shell 21, which is slidably connected to the support shell 4, and the first balloon 7 and the second balloon 8 are both slidably connected to the extrusion shell 21; a support rod 22, which is fixed to the cover plate 1, and the support rod 22 is slidably connected to a connecting rod 23, which is slidably connected to the first tube 2, and the connecting rod 23 is extruded and matched with the extrusion shell 21.
[0029] In the above scheme, a method of discharging the lubricating oil in the supporting shell 4 is proposed to facilitate the supporting shell 4 to enter the body; the extrusion shell 21 guides the first balloon 7 and the second balloon 8 to facilitate the insertion of the first balloon 7 and the second balloon 8 into the patient's body; the extrusion shell 21 is provided with a frustum consistent with the supporting shell 4; a push button is provided on the upper side of the connecting rod 23 to facilitate the doctor's operation.
[0030] Workflow: When the doctor moves the support shell 4 to fit the patient, the doctor simultaneously pushes the connecting rod 23, the connecting rod 23 slides along the support rod 22, the connecting rod 23 pushes the extrusion shell 21 to move downward, and the extrusion shell 21 squeezes the lubricating oil in the support shell 4, so that the lubricating oil in the support shell 4 is discharged and discharged into the patient's vagina. Then the doctor pushes the support shell 4 to enter the patient's vagina to facilitate subsequent work.
[0031] After the device is used, the doctor pushes the connecting rod 23 in the opposite direction to reset the extrusion shell 21.
[0032] Further disclosure based on the above scheme: Please refer to Figure 2 , Figure 5 and Figure 7 The extrusion mechanism also includes: an adjusting shell 31, which is rotatably connected to the supporting shell 4, the supporting shell 4 is provided with a plurality of first holes 401, the adjusting shell 31 is provided with a plurality of second holes 3101, the number of the second holes 3101 is consistent with the number of the first holes 401, the first hole 401 is communicated and cooperated with the adjacent second hole 3101, the second hole 3101 is blocked and cooperated with the extrusion shell 21, the aperture of the first hole 401 gradually increases from the side close to the first balloon 7 to the side away from the first balloon 7, and the second hole 3101 gradually increases from the side close to the first balloon 7 to the side away from the first balloon 7.
[0033] In the above scheme, a method for adjusting the flow rate of lubricating oil discharged from the support shell 4 is proposed, so that the device can discharge a suitable amount of lubricating oil according to the required amount of different patients; the lower side of the adjustment shell 31 is provided with a truncated table surface with the same shape as the lower side of the support shell 4, so that the adjustment shell 31 and the support shell 4 are completely fitted; in the initial state, the second hole 3101 and the adjacent first hole 401 are in a non-connected state to prevent the lubricating oil in the support shell 4 from overflowing; when the axis of the second hole 3101 is aligned with the axis of the adjacent first hole 401, the discharge amount of lubricating oil is the largest, and the dosage of lubricating oil discharged from the support shell 4 is controlled by adjusting the connection area between the second hole 3101 and the adjacent first hole 401; the aperture of the first hole 401 at the minimum point is equal to the aperture of the second hole 3101 at the maximum point, so that the aperture of the second hole 3101 and the adjacent first hole 401 are gradually changed, so that the flow area of the lubricating oil gradually increases during the discharge process, thereby reducing the resistance of the lubricating oil during discharge, reducing the stimulation to the patient's vaginal wall, and increasing the area covered by the lubricating oil on the inner wall of the vagina.
[0034] Workflow: Before inserting the support shell 4 into the patient's body, the doctor first rotates the adjustment shell 31 to gradually connect the second hole 3101 with the first hole 401, and releases the blockage of all the first holes 401 to facilitate the discharge of the lubricating oil in the support shell 4. Then the doctor continues to rotate the adjustment shell 31 to misalign the axis of the second hole 3101 with the axis of the first hole 401, and adjusts the connection area between the first hole 401 and the second hole 3101 to control the discharge amount of the lubricating oil, ensure that the dosage of the lubricating oil discharged corresponds to the patient's required amount, avoid excessive discharge of the lubricating oil, and cause the support shell 4 to fall off from the vagina, thereby ensuring the stability of the support shell 4 and all its parts, and avoiding the situation where too much lubricating oil covers the cervical surface.
[0035] After adjusting the adjustment shell 31 to a suitable position, the doctor stops rotating the adjustment shell 31 . After the device is used, the doctor rotates the adjustment shell 31 in the reverse direction to reset it.
[0036] The two balloons in the existing labor-inducing balloon will squeeze each other, mechanically stimulate the patient's cervix and vagina, and promote cervical ripening; after the labor-inducing balloon is placed in the body, due to the differences in the conditions of each pregnant woman, the positions of the two balloons cannot squeeze the cervix and vagina together, that is, the two existing balloons are in a fixed state, and the distance between them cannot be adjusted. For this purpose, the following solution is proposed, which is as follows: Further disclosure based on the above scheme: Please refer to Figure 3-Figure 6The connecting adjustment mechanism includes: a pushing shell 41, which is installed on the second connecting shell 6, and the pushing shell 41 is squeezed and matched with the first balloon 7; a first tube 42, which is arranged in the first connecting shell 5 and the second connecting shell 6, and the first tube 42 is fixedly connected and connected with the first drain pipe 43, and the first drain pipe 43 is connected with the pushing shell 41; a second tube 44, which is fixedly connected between the pushing shell 41 and the first balloon 7, and the pushing shell 41 and the first balloon 7 are both connected with the second tube 44; a third tube 45, which is arranged in the first connecting shell 5 and the second connecting shell 6, and the third tube 45 is fixedly connected and connected with the second drain pipe 46, and the second drain pipe 46 is connected with the second balloon 8.
[0037] In the above scheme, a method of pumping saline into the first balloon 7 and the second balloon 8 and adjusting the position of the first balloon 7 at the same time is mainly disclosed. By adjusting the first balloon 7, the first balloon 7 is moved to the target position; the push shell 41 is composed of a fixed plate and a telescopic tube (the two are fixedly connected to each other), wherein the fixed plate is fixedly connected to the second connecting shell 6, and after pumping saline into the telescopic tube, the telescopic tube expands, and it can only be extended and retracted in the vertical direction, so as to adjust the position of the first balloon 7; the first tube 42 and the third tube 45 are both connected to the external saline pumping device, and by turning on the external saline pumping device, the saline is pumped into the first balloon 7 and the second balloon 8 respectively; the second tube 44 connects the first balloon 7 and the push shell 41, so that the two are expanded or contracted synchronously; in this embodiment, the first tube 42 and the third tube 45 are both located in the first connecting shell 5 and the second connecting shell 6, that is, the first tube 42 and the third tube 45 are both complete (limited to this embodiment).
[0038] Workflow: After moving the second balloon 8 to the designated position (i.e., inside the cervix), the doctor pumps saline into the third tube 45 through an external saline pumping device. The saline passes through the third tube 45 and flows through the second drainage tube 46, and finally flows into the second balloon 8, thereby slowly expanding the second balloon 8 to squeeze the patient's cervix. After the second balloon 8 expands to the appropriate position, the doctor turns off the external saline pumping device.
[0039] After the second balloon 8 is inflated to a suitable degree and moved to a suitable position, the doctor pumps saline into the first tube 42 through an external saline pumping device. The saline flows through the first tube 42, through the first drainage pipe 43, and finally flows into the pushing shell 41. The saline in the telescopic tube of the pushing shell 41 increases and expands. During the expansion of the pushing shell 41, the pushing shell 41 pushes the first balloon 7 to move, thereby adjusting the position of the first balloon 7.
[0040] In the process of pushing the shell 41 to expand, the physiological saline in the shell 41 is pushed into the first balloon 7 through the second tube 44, so that the first balloon 7 is expanded. Through the above-mentioned operation, the first balloon 7 is moved synchronously in the process of expansion until the first balloon 7 moves to a suitable position. The doctor stops the external physiological saline pumping device, and the first balloon 7 stops moving and expanding. By adjusting the position of the first balloon 7 during its expansion, the first balloon 7 is located in the vagina near the outside of the cervix, ensuring that the first balloon 7 and the second balloon 8 cooperate to promote cervical ripening and initiate uterine contractions, thereby effectively inducing labor, thereby improving the applicability of the device and making it suitable for different patients.
[0041] After the device is used, the doctor uses the saline pumping device to extract the saline in the first balloon 7, the second balloon 8 and the push shell 41 in turn.
[0042] Further disclosure based on the above scheme: Please refer to Figure 6 The aperture of the first drain pipe 43 on the side close to the first pipe 42 is larger than the aperture on the side away from the first pipe 42 , and the aperture of the second drain pipe 46 on the side close to the third pipe 45 is larger than the aperture on the side away from the third pipe 45 .
[0043] In the above scheme, the shapes of the first drain pipe 43 and the second drain pipe 46 reduce the flow area of the saline solution, thereby reducing the flow rate of the saline solution and reducing the flow rate per unit time, thereby facilitating the control of the expansion degree of the first balloon 7 and the second balloon 8.
[0044] After the abortion balloon is placed, the doctor will pump saline into the two balloons inside. At this time, since the normal human body temperature is around 37°C, and the initial temperature of the saline is lower than the human body temperature, after the saline is injected into the body, it will irritate the patient.
[0045] Further disclosure based on the above scheme: Please refer to Figure 8-Figure 11, also includes: a temperature control mechanism, which is arranged in the second tube 3 and is used to control the temperature of the first balloon 7 and the second balloon 8, and the temperature control mechanism includes: a support plate 51, which is fixed to the first connecting shell 5 and is slidably connected to the second tube 3, and an outer shell 52 is fixed to the second connecting shell 6; the outer shell 52 is fixed to the support plate 51 and is slidably connected to the second tube 3; a diverter frame 53, which has two symmetrically distributed ones, both of which are arranged in the outer shell 52; a plurality of guide frames 54, which are arranged in the outer shell 52 at intervals and are respectively located in adjacent diverter frames 53, and the guide frames 54 are fixed to the second connecting shell 6, and the inner side of the outer shell 52 and all the diverter frames 53 , all the guide frames 54 and the upper side of the second connecting shell 6 together constitute a diversion cavity, and a heating device is arranged on the guide frame 54; a baffle plate 55 is fixedly connected to the upper side of the second connecting shell 6, the baffle plate 55 is located in the middle of the diversion cavity, and divides the diversion cavity into two parts, the baffle plate 55 is located between the two diversion frames 53, the first tube 42 and the third tube 45 are respectively connected to the adjacent parts of the diversion cavity, the lower side of the support plate 51, all the outer shells 52 and the upper sides of all the diversion frames 53 together constitute a diversion cavity, the baffle plate 55 divides the diversion cavity into two parts, the first tube 42 and the third tube 45 are respectively connected to the adjacent parts of the diversion cavity.
[0046] In the above scheme, a method of heating the physiological saline injected into the body is proposed to ensure that the temperature of the injected physiological saline corresponds to the patient's body temperature, reduce the temperature difference between the two, and thus reduce the stimulation to the patient; the heating device on the guide frame 54 heats the passing physiological saline, and the guide frame 54 is used to guide the flow of the physiological saline, extend the flow path of the physiological saline, and thus increase the heating time; the diversion cavity is cylindrical and is located between all the guide frames 54; the physiological saline entering the diversion cavity flows into the first tube 42 and the third tube 45 at the lower part, so that the heated physiological saline enters the first balloon 7 and the second balloon 8 respectively; the diversion cavity is located in the diversion cavity The upper side of the flow rack 53, and the upper side of the diverter rack 53 is set as an inclined surface, the height of the middle part is greater than the height of the surrounding side, so as to guide the physiological saline discharged from the upper first tube 42 and the third tube 45; the upper side of the baffle plate 55 is higher than the upper side of the diverter rack 53, and is located between the upper first tube 42 and the third tube 45, so as to distinguish the first tube 42 and the third tube 45 through the baffle plate 55; in this embodiment, the first tube 42 and the third tube 45 are divided into two parts, and the two parts are respectively located in the first connecting shell 5 and the second connecting shell 6, and the upper first tube 42 and the third tube 45 are connected with the lower first tube 42 and the third tube 45 through the diverter cavity and the guide cavity.
[0047] Working process: When the doctor moves the second balloon 8 to a suitable position and pumps saline into the second balloon 8, the doctor introduces saline into the third tube 45 at the upper part through the external saline pumping device, and the saline flows into the diversion cavity (i.e., the upper side of the diverter 53), flows outward along the diverter 53, and flows between the outer shell 52 and the diverter 53 (such as Fig.10 As shown), the saline then flows downward until it flows to the lower side of the outer shell 52, and then the saline flows upward along the diverter frame 53 and the guide frame 54 until the saline flows to the upper side of the diverter frame 53, and flows along the upper side of the guide frame 54 and between the diverter frame 53 into the diverter cavity (i.e., the upper side of the second connecting shell 6), and flows into the diverter cavity. The saline flows along the lower third tube 45 and enters the second balloon 8. During the flow of the saline, the guide frame 54 heats the saline passing through, so as to ensure that the saline entering the patient's body will not irritate the patient, thereby ensuring the normal use of the device and ensuring the smooth progress of the induced labor operation.
