Technical Field
[0001] The utility model relates to the field of medical equipment, in particular to a multifunctional production time measuring instrument. Background Art
[0002] When a pregnant woman is giving birth, the factors that affect the delivery include labor force, birth canal, fetus and mental psychology. The normal head presentation delivery mechanism can be described as: when the fetal presenting part passes through the birth canal, in order to adapt to the different shapes of various planes of the pelvis, it passively performs a series of adaptive rotations and passes through the birth canal with its smallest diameter. At this time, the doctor needs to use medical equipment to detect the size of the cervix, the height of the fetal head presentation, the angle and length of the episiotomy, etc.
[0003] Numerical measurement is an important means of observing and handling the labor process, such as the size of the cervix, the height of the presenting part, and the size of the episiotomy angle. The operator makes a subjective estimate of the cervix and the presenting part through vaginal digital examination, but the accuracy of the weight measurement result is poor due to personal experience and the thickness of the fingers. The measurement results of imaging techniques such as B-ultrasound are relatively accurate, but they are affected by the number of instruments, prices, imaging interference, and technical qualification requirements of operators, and are not practical for widespread clinical use. The size of the episiotomy angle is also mainly evaluated by visual inspection, and the position of the episiotomy is subjectively judged. The evaluation of the above situations is a big challenge for beginners.
[0004] The existing labor measurement instrument is used for external measurement in actual use, and it is difficult to insert it into the vaginal cervix for internal measurement. At the same time, the perineal incision angle and length of the pregnant woman have always relied on the doctor's own experience. The specific measurement process is not only inconvenient, but also not accurate enough.
[0005] In summary, the above structure is only used for external measurement during specific use. At the same time, when it comes to the episiotomy angle and episiotomy length of pregnant women, the specific measurement process is not only inconvenient but also not accurate enough.

[0011] The utility model is further configured that the finger sleeve is detachably arranged at the front end of the measuring instrument fixing rod and the measuring instrument support rod, and an array of protrusions is arranged inside the finger sleeve.
[0012] By adopting the above technical solution, the detachable finger cuffs can be easily replaced with finger cuffs of different inner diameters according to the thickness of the medical staff's fingers, thereby ensuring the stability of the measuring instrument fixing rod and the measuring instrument support rod on the medical staff's fingers. At the same time, the array of protrusions in the finger cuffs can further improve the stability of the finger cuffs on the medical staff's fingers.
[0013] The utility model is further configured such that the side edges of the measuring instrument fixing rod and the measuring instrument supporting rod are both configured to be smooth.
[0014] By adopting the above technical solution, when the measuring instrument fixing rod and the measuring instrument support rod are placed into the pregnant woman's vagina to find the edge of the cervical opening, the measuring instrument fixing rod and the measuring instrument support rod can be effectively prevented from causing certain damage to the pregnant woman's vagina, thereby further improving the overall safety of the device.
[0015] The utility model is further configured such that the connection between the measuring instrument fixing rod and the measuring instrument support rod is configured to be smooth.
[0016] By adopting the above technical solution, medical personnel can accurately adjust the distance between the measuring instrument fixing rod and the measuring instrument support rod when using it, which can effectively reduce the instability of angle adjustment.
[0017] The utility model is further configured that the front end of the finger sleeve is configured in an arc shape.
[0018] By adopting the above technical solution, when medical personnel insert the measuring instrument fixing rod and the measuring instrument supporting rod into the vagina of a pregnant woman, the damage to the vagina of the pregnant woman caused by the front end of the finger stop sleeve can be reduced.
[0019] The utility model is further configured that a through hole for the meter to pass through is opened on the measuring instrument support rod.
[0020] By adopting the above technical solution, the through hole facilitates the reciprocating sliding of the measuring instrument support rod on the meter, thereby further improving the stability of the overall sliding.
[0021] The utility model is further configured such that the meter is detachably disposed in the slot.
[0022] By adopting the above technical solution, the detachable setting makes it easy for subsequent medical personnel to clean the device, and also makes it easy to maintain and replace it later.
[0023] In summary, the utility model mainly has the following beneficial effects:
[0024] The utility model can conveniently cover the fixing rod and the supporting rod of the measuring instrument on the index finger and the middle finger of the medical staff through the finger sleeve, and then insert the finger sleeve into the vagina of the pregnant woman to find the edge of the cervical opening, and then place the index finger and the middle finger on both sides of the maximum diameter of the cervical opening. The size of the cervical opening diameter can be visually observed through the meter, and the distance from the presenting part to the vaginal opening can also be intuitively read through the scale, so that it is convenient for the medical staff to judge the height of the presenting part. At the same time, the medical staff can also adjust the appropriate angle according to the meter of the device, and combine the length measurement of the scale to conveniently determine the perineal episiotomy angle and the episiotomy length, thereby improving the overall practicality of the device.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0030] The following describes an embodiment of the utility model based on its overall structure.
[0031] Embodiment 1
[0032] A multifunctional production time measuring instrument, such as Figure 1-Figure 3 As shown, it includes a measuring instrument fixing rod 1, a measuring instrument support rod 2, a rotating mechanism and a measuring mechanism. The connection between the measuring instrument fixing rod 1 and the measuring instrument support rod 2 is smooth. When used by medical personnel, the distance between the measuring instrument fixing rod 1 and the measuring instrument support rod 2 can be accurately adjusted, which can effectively reduce the instability of angle adjustment. When in use, the medical personnel wear disposable sterile gloves, put their own index finger and middle finger into the finger sleeve 6, and insert them into the pregnant woman's vagina after applying paraffin oil to find the edge of the cervical opening. After determining the edge of the cervical opening, the middle finger and index finger are placed on both sides of the maximum diameter of the cervical opening. As the middle finger and index finger move, the measuring instrument fixing rod 1 and the measuring instrument support rod 2 are driven to open, thereby realizing that the angle of the meter 4 is opened. The size of the cervical diameter can be observed intuitively through the meter 4. After the measurement of the cervical size is completed, the middle finger and index finger are put together to close the meter fixing rod 1 and the meter support rod 2. The distance from the presenting part to the vaginal opening can be directly read from the scale end on the scale 5, thereby indirectly judging the height of the presenting part. At the same time, before the lateral incision is performed for the highly bulging perineum, the perineal joint is used as a fulcrum, and one side of the meter fixing rod 1 is placed parallel to the midline of the perineum, and the meter support rod 2 is opened to the left. According to the condition of the perineum of the parturient, the angle of the meter 4 is adjusted between 45-60°. The side opened to the left that fits the perineum is the episiotomy position, which is then marked to facilitate the subsequent accurate finding of the episiotomy position, thereby improving the overall practicality of the device.
[0033] See also Figure 1 and Figure 2 The finger sleeve 6 is detachably arranged at the front end of the measuring instrument fixing rod 1 and the measuring instrument support rod 2, and an array of protrusions is arranged inside the finger sleeve 6. The detachable finger sleeve 6 is convenient for replacing finger sleeves 6 with different inner diameters according to the thickness of the medical staff's fingers, thereby ensuring the stability of the measuring instrument fixing rod 1 and the measuring instrument support rod 2 at the medical staff's fingers. At the same time, the array of protrusions in the finger sleeve 6 can further improve the stability of the finger sleeve at the medical staff's fingers.
[0034] See also Figure 1 and Figure 2The sides of the measuring instrument fixing rod 1 and the measuring instrument support rod 2 are both smooth. When the measuring instrument fixing rod 1 and the measuring instrument support rod 2 are inserted into the vagina of a pregnant woman to find the edge of the cervical opening, the measuring instrument fixing rod 1 and the measuring instrument support rod 2 can be effectively prevented from causing certain damage to the pregnant woman's vagina, thereby further improving the overall safety of the device.

The slot 3 facilitates folding the measuring instrument support rod 2 and the measuring instrument fixing rod 1 after the device is used, so as to facilitate its placement. At the same time, the rough surface in the slot 3 facilitates increasing the sliding friction between the measuring instrument support rod 2 and the measuring instrument fixing rod 1, thereby preventing the measuring instrument support rod 2 from easily sliding out of the measuring instrument fixing rod 1 during measurement, thereby further improving the stability of the overall device during use.
[0037] The working principle of the utility model is as follows: when in use, the medical staff inserts the index finger and the middle finger into the finger sleeve 6, and then inserts the measuring instrument fixing rod 1 and the measuring instrument support rod 2 into the vagina to find the edge of the cervical opening, and then places the middle finger and the index finger on both sides of the maximum diameter of the cervical opening, and the size of the cervical opening diameter can be intuitively displayed through the function of the meter 4, and the distance from the presenting part to the vaginal opening can be directly read through the function of the scale 5, so as to indirectly judge the height of the presenting part, and one end of the measuring instrument fixing rod 1 is placed parallel to the midline of the perineum, and then the measuring instrument support rod 2 is rotated to one side at a fixed angle, and the angle between the measuring instrument fixing rod 1 and the measuring instrument support rod 2 is adjusted, so as to facilitate the subsequent accurate finding of the episiotomy position, thereby improving the overall practicality of the device.
