Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an intelligent device for emergency midwifery in obstetrics and gynecology. Background Art

[0002] When a pregnant woman in obstetrics and gynecology gives birth naturally, dystocia may occur due to reasons such as fetal head edema, excessive size, or abnormal position. In such cases, medical staff first need to promptly perform vaginal dilation on obstetrics and gynecology patients to facilitate a smooth delivery. Currently, emergency vaginal dilation relies on doctors manually or using simple auxiliary vaginal dilation instruments for dilation, and then using a midwifery clamp or a negative pressure suction device. It mainly relies on the experience of doctors, the force is difficult to control, and it is very laborious, causing pain to patients and exhaustion to doctors. Therefore, some applicants in the market have studied an automated midwifery device, and its application number is 2019109741261. The device includes: an operation table, on which a vaginal dilation frame, an inflation device, and a water circulation device are provided, and a vaginal dilation head is provided on the side of the vaginal dilation frame; the vaginal dilation head includes: a vaginal dilation ring, and from the inside to the outside, the vaginal dilation ring is successively a protective support layer, a vaginal dilation trachea, and a water-driven tube. The vaginal dilation trachea is connected to the inflation device, and the water-driven tube is connected to the water circulation device. The present invention combines pneumatic vaginal dilation and water-driven vaginal dilation and applies them to the vaginal dilation work during emergency midwifery.

[0003] The above technical solution can achieve the purpose of pneumatic vaginal dilation by gradually increasing the volume of the trachea. However, the above pneumatic vaginal dilation process cannot detect the force of vaginal dilation, has a low degree of intelligence, cannot control the water-driven expansion and contraction movement according to the contraction of the vagina, and continuous dilation will also cause discomfort to patients. Therefore, an intelligent device for emergency midwifery in obstetrics and gynecology is proposed. Summary of the Invention

[0025] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore,

[0026] the illustrations only show the components related to the present invention and are not drawn according to the number, shape, and size of the components in actual implementation. The states, quantities, and proportions of the components in actual implementation may be arbitrarily changed, and the component layout state may also be more complex.

[0027] An intelligent emergency midwifery device for obstetrics and gynecology, as Figures 1-5 shown, includes a vaginal dilatation unit 100 and a monitoring and control unit 200;

[0028] The vaginal dilatation unit 100 includes a bracket 110, a fixing frame 120, a support rod 130, a connecting rod 140, a vaginal dilatation head 150, a driving mechanism 160, and a rotating frame 170. The monitoring and control unit 200 includes a control device 210, a pressure sensor 220, a distance sensor 230, and a uterine contraction signal receiving module. The fixing frame 120 is installed on the bracket 110, and the bracket 110 is supported on the ground or clamped on the operating table. A plurality of support rods 130 are rotatably connected to the fixing frame 120. One end of the connecting rod 140 is rotatably connected to the support rod 130, and a pressure sensor 220 is arranged between the connecting rod 140 and the support rod 130. The pressure sensor 220 is used to detect the pressure value between the connecting rod 140 and the support rod 130. The end of the connecting rod 140 is fixedly connected to the vaginal dilatation head 150. The driving mechanism 160 is arranged on the fixing frame 120. The driving mechanism 160 is used to push the support rod 130, and the support rod 130 then pushes the connecting rod 140, so that a plurality of vaginal dilatation heads 150 expand the patient's external vagina. The control device 210 is arranged on the fixing frame 120 through the rotating frame 170. The distance sensor 230 is arranged on the control device 210. The distance sensor 230 is used to detect the distance from the fetus. The uterine contraction signal receiving module is arranged in the control device 210. The uterine contraction signal receiving module is connected to an external electronic fetal monitor. The uterine contraction signal receiving module is used to receive the uterine contraction signal emitted by the uterine contraction probe in the electronic fetal monitor and send it to the control device 210.

[0029] During emergency midwifery, multiple vaginal dilator heads 150 are respectively propped against the vulva of the parturient. The driving mechanism 160 is activated through the control device 210 to push the support rod 130. The support rod 130 uses the connecting rod 140 to spread open the vaginal dilator head 150 to achieve vaginal dilation. The pressure sensor 220 detects the pressure between the connecting rod 140 and the support rod 130 and transmits the pressure signal to the control device 210. Since the distance from the connection point of the connecting rod 140 and the support rod 130 to the pressure sensor 220 and the distance from the pressure sensor 220 to the vaginal dilator head are both fixed, the control device 210 calculates the pressure received by the vaginal dilator head based on these two distances. The distance sensor 230 detects the distance from the fetal head and also detects the distance from the vulva and transmits them to the control device 210. Through the triangular relationship, the relative position between the fetal head and the vulva is calculated. According to the relative position between the head and the vulva, the operation of the vaginal dilation unit 100 is adjusted. When the electronic fetal monitor detects uterine contractions, the control device 210 adjusts the vaginal dilation unit 100 to the first state, that is, the vulva is spread open through the driving mechanism 160 until the pressure sensor 220 reaches the pre-set maximum value, so that the fetal head can reach the vulva as soon as possible. When the uterine contractions end, the control device 210 adjusts the vaginal dilation unit 100 to the second state, that is, controls the driving mechanism 160 to contract until the pressure sensor 220 reaches the pre-set sub-high value, allowing the vulva to have a buffering time and reducing the pain of the parturient. During this period, the vulva will naturally contract periodically. When contracting, the control device 210 adjusts the vaginal dilation unit 100 to the third state, that is, controls the driving mechanism 160 to contract until the pressure sensor 220 reaches the pre-set medium value, and then returns to the second state after contraction, so as to realize the contraction and expansion of multiple vaginal dilator heads 150 according to the natural contraction frequency of the vulva, further reducing the delivery pain of the parturient. When the fetal head is in the position of the vulva, the control device 210 adjusts the vaginal dilation unit 100 to the first state until the head completely slides out of the vulva, and rotates the control device 210 through the rotating frame 170 to move it out from the inner circle of the fixed frame 120.

[0030] As an implementation manner of the present invention, the fixed frame 120 is of a ring structure, which is convenient for the medical staff to perform midwifery operations, such as adjusting the fetal position through a negative pressure device or a midwifery clamp.

[0031] As an implementation manner of the present invention, the driving mechanism 160 includes a linear motor 161 and a push rod 162. The linear motor 161 is installed on the fixed frame 120. The push rod 162 is slidably connected to the fixed frame 120. The push rod 162 is connected to the linear motor 161. The push rod 162 is movably connected to the support rod 130. The push rod 162 is used to push the support rod 130 so that the vaginal dilator head 150 is propped up.

[0032] As an implementation manner of the present invention, a CCD camera 211 and a display screen 212 are further provided on the control device 210. The CCD camera 211 is used to capture a vaginal video and display it through the display screen 212. The display screen 212 also displays the pressure data received by the control device 210. When the display screen 212 is a touch display screen, the control button function of the control device 210 can be integrated into the touch display screen.

[0033] As an implementation manner of the present invention, the rotating frame 170 includes a damping rotating shaft 171 and an operating rod 172. The damping rotating shaft 171 is fixedly connected to the fixed frame 120, and the operating rod 172 is arranged on the damping rotating shaft 171. The end of the operating rod 172 is fixedly connected to the control device 210.

[0034] As an implementation manner of the present invention, the vaginal dilator head 150 includes an inner fixing plate 151 and an outer flexible coating layer 152. The inner fixing plate 151 is fixedly connected to the connecting rod 140, and the outer flexible coating layer 152 wraps around the surface of the inner fixing plate 151. Specifically, the inner fixing plate 151 can be made by bending a stainless steel plate, and the outer flexible coating layer 152 can be made of medical silicone to improve comfort. A lubricating hole 153 is opened on the outer flexible coating layer 152, and a cavity communicating with the lubricating hole 153 is provided between the outer flexible coating layer 152 and the inner fixing plate 151. A guiding tube 154 communicating with the cavity is provided on the outer flexible coating layer 152. The guiding tube 154 is connected to a liquid supply device, and the liquid supply device is connected to the control device 210. When the fetal head is in the position of the vulva, the liquid supply device fills the guiding tube 154 with a lubricating medium, so that the lubricating medium is discharged from the lubricating hole 153, playing a lubricating role during childbirth and improving the childbirth efficiency.

[0035] As an implementation manner of the present invention, a light strip 180 is provided on the fixed frame 120 for supplementing light to the vagina during childbirth to facilitate the doctor's observation.

[0036] Finally, it should be noted that the above implementation manners are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred implementation manners, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
