Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a cervical os detector. Background Art

[0002] During the natural delivery process of pregnant women in the hospital, as the uterine contractions proceed, the cervix gradually opens and the fetal head gradually descends. Especially for some pregnant women who need painless delivery, according to existing textbooks and medical codes, anesthesia can only be performed when the cervix dilates to 3 cm. Therefore, doctors and midwives need to detect the size of the cervical dilation of pregnant women at regular intervals. At present, most doctors and midwives move their fingers to the cervical position of pregnant women and use their fingers to detect the size of the cervical dilation. Different doctors and midwives have different fingers, and the results obtained have large deviations. Therefore, if the measurement of the cervical size is based solely on personal experience, there will be certain errors, which indirectly leads to the inability of doctors and midwives to do the next step of delivery in time. For this reason, we propose a cervical detector. Utility Model Content

[0003] The utility model aims to provide a cervical opening detector which can accurately measure the dilation size of the cervical opening of parturient women.

[0004] To this end, the technical solution adopted in this utility model is:

[0005] A cervical os detector, comprising:

[0006] A base, wherein a lifting rod is slidably connected inside the base, a support plate is fixedly connected to the side wall of the lifting rod, a limit rod is slidably connected to the support plate, and an elastic member is sleeved on the outer surface of the limit rod;

[0007] A bracket, wherein the bracket is fixed to the top of the lifting rod, the top of the bracket is fixedly connected with a support sleeve, the support sleeve is slidably connected with a push rod, and one end of the push rod is fixedly connected with a clamping column;

[0008] The detection rod is rotatably connected to one end of the bracket, a strip groove matched with the clamping column is opened on the side wall of the detection rod, and the clamping column is sleeved in the strip groove.

[0009] Based on the above technical solution, its use principle and the technical effects produced are as follows:

[0010] When it is necessary to detect the patient's cervical os, first disinfect the detection rod in all directions, and then place the base on the delivery bed or midwifery chair to make the device more stable when detecting the size of the parturient's cervical os, and then pull the limit rod to disengage it from the limit hole to unlock the lifting rod, and then according to the height of the parturient's cervical os, pull the lifting rod out of the base to make the detection rod at an appropriate height, and then release the limit rod so that it can be re-engaged in the limit hole under the action of the elastic member, and then fix the limit rod to lock the lifting rod, and then the medical staff holds the handle with one hand and pushes the push rod with the other hand to drive the clamping column to move, and the adaptation relationship between the clamping column and the strip groove can be used to drive the two detection rods to deflect outward at the same time. When the detection rod expands outward to the cervical os wall, the scale size on the push rod located on the side of the support sleeve facing the medical staff can be observed to measure the size of the parturient's cervical os at this time. The operation is simple, convenient and practical, and the detection accuracy is high.

[0018] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0019] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0020] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0021] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.);

[0022] An active connection is a connection in which parts or components are fixed so that they can move relative to each other.

[0023] The above technical solution of the utility model has the following beneficial technical effects:

[0024] 1. In the utility model, the size of the cervix of the parturient can be accurately measured by the cooperation of the support, the push rod, the detection rod and other structures.

Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.

[0032] According to the concept of this application, Figures 1 to 3 An embodiment of a cervical os detector for detecting the size of the cervical os of a parturient is described below. Specifically, the cervical os detector is constructed as an integrated structure, which has three components, namely a base 1, a bracket 6 and a detection rod 10. Through the mutual cooperation of the provided bracket 6, the push rod 8, the detection rod 10 and other structures, the size of the cervical os of a parturient can be accurately measured. Compared with the traditional "open fingers" judgment method, the detection accuracy is high, which is helpful for judging the production process. In addition, through the mutual cooperation of the provided base 1, the lifting rod 2, the limit rod 4, the elastic member 5 and other structures, the device can be prevented from dangling and shaking in the air when detecting the size of the cervical os of a parturient, and the stability during detection can be enhanced. At the same time, by adjusting the use height of the lifting rod 2, the detection height of the detection rod 10 can also be adaptively adjusted.

[0033] Combination Figure 1-3 As shown, the utility model provides a cervical os detector, comprising:

[0034] A base 1, a lifting rod 2 is slidably connected inside the base 1, a support plate 3 is fixedly connected to the side wall of the lifting rod 2, a limit rod 4 is slidably connected to the support plate 3, and an elastic member 5 is sleeved on the outer surface of the limit rod 4;

[0035] A bracket 6 is fixed on the top of the lifting rod 2. A support sleeve 7 is fixedly connected to the top of the bracket 6. A push rod 8 is slidably connected to the support sleeve 7. One end of the push rod 8 is fixedly connected to a clamping column 9.

[0036] The detection rod 10 is rotatably connected to one end of the bracket 6 . A strip groove 11 matching the clamping column 9 is formed on the side wall of the detection rod 10 , and the clamping column 9 is sleeved in the strip groove 11 .

[0037] The base 1 is mainly used to provide support. In some embodiments, the overall shape of the base 1 can be set to a cylindrical, rectangular or prism shape. According to the technical solution of this embodiment, the overall shape of the base 1 is set to a rectangular shape. The rectangular base 1 is placed on a delivery bed or an obstetric chair to facilitate the detection of the size of the cervix of the parturient and make the device more stable. A storage groove compatible with the lifting rod 2 is opened inside the base 1. The storage groove is used to facilitate the storage of the lifting rod 2, thereby facilitating the adjustment of the extension length of the lifting rod 2.

[0038] According to the technical solution of this embodiment, a plurality of limiting holes 12 compatible with the limiting rod 4 are opened on the side wall of the base 1. The limiting hole 12 is set as a circular blind hole. When the limiting rod 4 is inserted into the limiting hole 12, the limiting rod 4 can be fixed, thereby locking the lifting rod 2, so that the use height of the bracket 6 and the detection rod 10 can be adjusted according to actual needs. When the detection is completed, the limiting rod 4 is pulled to disengage it from the limiting hole 12, and the lifting rod 2 can be unlocked and stored.

[0039] According to the technical solution of this embodiment, one end of the elastic member 5 is fixed on the limit rod 4, and the other end is fixed on the bracket 6. The elastic potential energy provided by the elastic member 5 is used to drive the limit rod 4 to reset.

[0040] One end of the bracket 6 away from the detection rod 10 is fixedly connected with a handle 13, which is convenient for medical personnel to hold the Zhiji Ai during detection and further enhances the stability during use.

[0041] There are two detection rods 10, and the two detection rods 10 are symmetrically arranged on the bracket 6. In some embodiments, the detection rod 10 can be rotatably connected to the bracket 6 through a pin shaft, a bearing, etc. According to the technical solution of this embodiment, the detection rod 10 is rotatably connected to the bracket 6 through a pin shaft.

[0042] Furthermore, the detection rod 10 includes a straight portion 101 and an arc portion 102, and the strip groove 11 is opened on the straight portion 101. The arrangement of the straight portion 101 and the strip groove 11 facilitates driving the detection rod 10, and the arrangement of the arc portion 102 is mainly used to adapt to the human cervical structure to facilitate detection.

[0043] Furthermore, a scale 14 is provided on the surface of the push rod 8. By pushing the push rod 8 to drive the clamping column 9 to move, the adaptation relationship between the clamping column 9 and the strip groove 11 can be utilized to drive the two detection rods 10 to deflect outward or inward at the same time, and then the size of the scale 14 located on the push rod 8 at the support sleeve 7 can be used to measure the distance between the two detection rods 10, thereby measuring the size of the cervix of the parturient.

[0044] Specifically, when it is necessary to detect the cervix of the patient, the detection rod 10 is first disinfected in all directions, and then the base 1 is placed on the delivery bed or the midwifery chair to facilitate the detection of the size of the cervix of the parturient and make the device more stable. Then, the limit rod 4 is pulled to disengage it from the limit hole 12, and the lifting rod 2 can be unlocked. Then, according to the height of the cervix of the parturient, the lifting rod 2 is pulled out from the base 1 so that the detection rod 10 is at an appropriate height. Then, the limit rod 4 is loosened so that it is re-stuck in the limit hole 12 under the action of the elastic member 5. The limit rod 4 can be fixed to lock the lifting rod 2, and then the medical staff holds the handle 13 with one hand and pushes the push rod 8 with the other hand to drive the clamping column 9 to move, and the adaptation relationship between the clamping column 9 and the strip groove 11 can be used to drive the two detection rods 10 to deflect outward at the same time. When the detection rod 10 expands outward to the cervical wall, the size of the cervical size of the parturient can be measured by observing the size of the scale 14 on the push rod 8 located on the side of the support sleeve 7 facing the medical staff. The operation is simple, convenient and practical, and the detection accuracy is high.
