[0002] With the continuous improvement of medical standards, the number of cesarean sections in hospitals has gradually increased. When the maternal and fetal risks associated with continued pregnancy are higher than the maternal and fetal risks brought about by termination of pregnancy, induced labor is often performed clinically. In the process of induced labor for pregnant women, artificial rupture of membranes is a relatively common method of induced labor.

[0003] A Chinese patent with application number CN202121244736.5 discloses an artificial membrane rupture device for delivery room; it includes a handle, a movable rod is connected to the inner thread of the handle, the movable rod passes through the handle forward and backward, the front end of the movable rod is fixedly connected to a membrane piercing member, the membrane piercing member is at an eccentric position at the front end of the movable rod, and the rear end of the movable rod is fixedly connected to an operating screw cap; the utility model has high safety, avoids stabbing the fetus and the operator, and also reduces the physical and psychological pressure of the parturient.

[0004] However, the device needs to accurately assess the position of the cervical opening before artificial rupture of membranes. Clinically, it is generally performed by inserting the index and middle fingers of the right hand into the vagina for exploration. In the above methods, medical personnel rely on subjective assessment to judge the position of the cervical opening, which is inaccurate and affects the subsequent artificial rupture of membranes process. In addition, repeated vaginal examinations are likely to cause discomfort and infection to the mother.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0029] A connecting block 6 is installed at one end of the membrane rupture member 2, and the connecting block 6 matches with the groove 5;

[0030] Among them, a mounting head 7 is snap-connected at one end of the cylinder 1, a cylindrical groove 8 is opened in the mounting head 7, a fixing piece 9 is elastically fitted in the mounting head 7, and the fixing piece 9 cooperates with the connecting block 6. A storage box 12 is installed on one side of the cylinder 1, and a soft ruler 13 is slidably fitted in the storage box 12. A plurality of scale protrusions 16 are installed on the other side of the cylinder 1 and the mounting head 7.

[0031] A plurality of first elastic members 19 are installed between one side of the moving block 4 and the cylinder 1 .

[0032] Among them, the barrel 1 and the mounting head 7 are engaged to form a cylindrical shape of about 12 cm long and 1 cm wide. The head end of the mounting head 7 is conical. The overall surface of the barrel 1 and the mounting head 7 is smooth to avoid damaging the vaginal wall. The barrel 1 and the mounting head 7 as a whole can be reused after sterilization.

[0033] The application of one aspect of this embodiment is as follows: first, the operation is performed in a sterile environment, and then the medical staff wears sterile gloves and installs the membrane rupturing member 2 to be used, so that the connecting block 6 enters the groove 5, and then the installation head 7 is engaged with one end of the cylinder 1, so that the fixing member 9 in the installation head 7 squeezes and fixes the connecting block 6 to fix the membrane rupturing member 2, and then the cylinder 1 is inserted into the vagina. During the insertion process, the soft ruler 13 can be pulled out from the storage box 12, and the size of the cervical dilation is measured using the soft ruler 13. The height of the fetal presenting part is determined by touching the position of the fetal head from the ischial spine with a finger, and then when performing artificial membrane rupture, the slide bar 3 is pushed to make the slide bar 3 drive the moving block 4 and the membrane rupturing member 2 to move, so that the membrane rupturing member 2 performs artificial membrane rupture. After the artificial membrane rupture is successful, the first elastic member 19 will drive the moving block 4 and the membrane rupturing member 2 to move, so that the membrane rupturing member 2 is retracted into the cylinder 1 to avoid needle stick injuries to medical staff.

[0034] By means of the provided soft tape measure 13, when the cylinder body 1 of the device is inserted for artificial rupture of membranes, the soft tape measure 13 can be pulled out to measure the size of the dilation of the cervical opening, thereby facilitating the subsequent artificial rupture of membranes process for medical personnel and reducing the discomfort and infection of parturient women caused by repeated vaginal examinations. By means of the provided scale protrusions 16, the fingers can touch a plurality of scale protrusions 16, and the height of the fetal presenting part can be determined according to which scale protrusion the finger touches from the distance between the fetal head and the ischial spine. By means of the provided fixing piece 9, when the mounting head 7 is engaged and connected with one end of the cylinder body 1, the fixing piece 9 squeezes and fixes the connecting block 6, thereby fixing the membrane rupture piece 2, facilitating the stable movement of the membrane rupture piece 2 for artificial rupture of membranes.

[0035] like Figure 2 As shown, a plurality of slots 10 are provided at one end of the cylinder 1 of this embodiment, a plurality of blocks 11 corresponding to the plurality of slots 10 are provided at one end of the mounting head 7, the plurality of blocks 11 are respectively matched with the plurality of slots 10, and a rounded corner is provided at one end of the blocks 11 matched with the slots 10, wherein a plurality of second elastic members 20 are provided between one side of the fixing member 9 and one side of the inner wall of the mounting head 7. By means of the provided blocks 11, the blocks 11 can be engaged with the slots 10 to fix the mounting head 7, so that the elastic force of the second elastic member 20 drives the fixing member 9 to squeeze and fix the connecting block 6 and the membrane breaking member 2.

[0036] like Figure 4 As shown, the tape measure 13 of this embodiment is provided with digital markings, and a pull ring 15 is installed at one end of the tape measure 13 away from the storage box 12. The pull ring 15 can be used to pull out the tape measure 13, so that medical personnel can evaluate the size of cervical dilation through the digital markings on the tape measure 13.

[0037] like Figure 4As shown, the storage box 12 of this embodiment is equipped with a winding device that matches the tape measure 13, and the storage box 12 is elastically matched with an elastic clip 14, which matches the tape measure 13. The elastic clip 14 can squeeze and fix the pulled tape measure 13, so that the tape measure 13 will not be pulled into the storage box 12 by the winding device, which is convenient for medical personnel to observe the tape measure 13.

[0038] like Figure 2 As shown, the barrel 1 and the mounting head 7 of this embodiment are provided with scale marks at positions corresponding to the multiple scale protrusions 16. The multiple scale protrusions 16 can enable medical personnel to determine the position through the scale marks on the scale protrusions 16.

[0039] like Figure 3 As shown, two fixing rings 17 are installed on the barrel 1 of this embodiment, and a pressing block 18 is installed at one end of the slide rod 3 that passes through the barrel 1. Through the setting of the fixing ring 17, medical personnel can take the device through the two fixing rings 17 and push the pressing block 18 to move the membrane rupturing member 2 to perform artificial membrane rupture.

[0040] In order to save cost and simplify operation, a new embodiment is provided: the barrel 1 of this embodiment is fixedly connected to the mounting head 7, the membrane rupturing member 2 is fixedly connected to the moving block 4, and the tape measure 13 is stored on one side of the barrel 1, so that the device has the conditions of a disposable item, which can prevent and reduce cross infection during operation.
