Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a pain feedback gripping device for childbirth. Background Technology

[0002] Childbirth is a complex and important physiological process, usually accompanied by significant pain and discomfort. Labor pain primarily stems from uterine contractions, cervical dilation, and pressure from surrounding tissues. These factors work together to cause intense pain, reaching a VAS score of 8-10, significantly higher than chronic pain and other acute pain.

[0003] In addition, psychological factors also have a significant impact on the perception of pain; tension and anxiety can exacerbate the pain experience. Therefore, many pregnant women seek various pain relief methods, such as drug anesthesia and painless childbirth, to help alleviate pain and discomfort during labor.

[0004] In clinical practice, accurate assessment of labor pain is crucial for implementing individualized analgesia. Currently, it mainly relies on medical staff to make judgments through empirical methods such as observing the mother's facial expressions, asking about subjective feelings, and monitoring the frequency of uterine contractions. This subjective assessment method has obvious individual differences and lag, and cannot capture the dynamic changes in pain in real time.

[0005] The lack of objective and quantitative assessment methods often leads to inappropriate timing and dosage of analgesics, which may affect uterine contractions and thus the labor process, and exacerbate the physical and mental burden on the mother. In particular, the unconscious grasping movements and vocalizations produced by the mother due to severe pain during labor are important physiological signals that have not yet been effectively converted into quantifiable assessment parameters.

[0006] In conclusion, how to provide a pain feedback grip device for childbirth is a technical problem that urgently needs to be solved. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pain feedback gripping device for childbirth. The device detects the pressure on the soft area of ​​the gripping body through a pressure sensing module, assesses the degree of pain based on the pressure, and outputs the assessment result through a feedback output module.

[0008] This utility model provides a childbirth pain feedback gripping device, including a gripping body; the gripping body is provided with a soft area, and a pressure sensing module is provided in the soft area to detect the pressure on the soft area;

[0009] The control center uses the pressure detected by the pressure sensing module to assess the level of pain and outputs the assessment results through the feedback output module.

[0010] Furthermore, the soft area includes several recessed finger grooves that match the curvature of the user's fingers and can fit the user's fingers.

[0011] Furthermore, anti-slip ridges are provided between the adjacent finger grooves.

[0012] Furthermore, the feedback output module includes a display screen, which is mounted on the grip body or set independently of the grip body.

[0013] Furthermore, the feedback output module includes at least one LED light disposed on the surface of the grip body.

[0014] Furthermore, the feedback output module includes a vibration motor disposed within the grip body.

[0015] Furthermore, the gripping body is provided with a fixing component, which fixes the gripping body to the user's hand, wrist or arm.

[0016] Furthermore, the fixing component includes an adjustable strap, the length of which is adjustable and both ends are detachably connected.

[0017] Furthermore, it also includes a sound acquisition module for collecting the pregnant woman's voice data; the control center uses the sound data to assess the level of pain and outputs the assessment results through a feedback output module.

[0018] Furthermore, it includes a right-hand gripping body corresponding to the right hand and a left-hand gripping body corresponding to the left hand.

[0019] By adopting the above technical solution, this utility model, as an example, has the following advantages and positive effects compared with the prior art:

[0020] By combining pressure sensing and sound acquisition modules, the device transforms the unconscious gripping movements and vocal responses caused by pain in labor—important physiological signals—into effective and quantifiable assessment parameters. The control center can objectively assess the pregnant woman's pain during labor based on these parameters and output the assessment results through a feedback output module. This provides an intelligent device integrating real-time monitoring, assessment, and feedback of labor pain, offering effective support for pain management during childbirth for medical personnel. Furthermore, the ergonomic design of the device's main body and the design of its fixation components make the entire device easier to use and secure, ensuring the effectiveness of monitoring and improving the comfort of the pregnant woman.

It should be noted that the technical features or combinations of technical features described in the following embodiments should not be considered isolated; they can be combined with each other to achieve better technical effects. In the accompanying drawings of the following embodiments, the same reference numerals appearing in each drawing represent the same features or components, which can be applied to different embodiments. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of the utility model. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the utility model, should fall within the scope of the technical content disclosed in the utility model. The scope of the preferred embodiments of this utility model includes other implementations, wherein functions may be performed not in the order stated or discussed, including substantially simultaneously or in reverse order, according to the functions involved. This should be understood by those skilled in the art to which the embodiments of this utility model pertain.

[0033] Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] This utility model provides a pain feedback gripping device 100 for childbirth, such as Figure 1 As shown.

[0035] It includes a gripping body 200 for pregnant women to grasp.

[0036] The gripping body 200 is provided with a soft area 210. In a typical implementation, the soft area 210 is located on the side of the gripping body 200 and is made of elastic material, such as elastic silicone or elastic sponge. It can deform when subjected to pressure and return to its original shape when the pressure is removed.

[0037] The soft area 210 is provided with a plurality of recessed finger grooves 220. In a typical embodiment, the surface of the soft area 210 is provided with a total of five recessed finger grooves 220, located on both sides of the grip body 200, such as... Figure 1 As shown, four finger grooves 220 are provided on one side, corresponding to the natural positions of the index finger, middle finger, ring finger, and little finger, respectively. Figure 2 As shown, a finger groove 220 is provided on the opposite side, corresponding to the natural position of the thumb.

[0038] The concave curvature of the finger grooves 220 is designed to match the curvature of the fingertip, and the spacing between the finger grooves 220 corresponds to the average distance between the fingers of an adult woman. This allows the user's fingers to naturally sink into the finger grooves 220 when gripping, with the fingertip and the concave curvature of the finger grooves 220 fitting together, making it easier to grip. Furthermore, the fingers can naturally separate without squeezing each other when gripping.

[0039] The pressure sensing module is located inside the finger groove 220, and the pressure applied by the finger to the finger groove 220 can be accurately transmitted to the pressure sensing module.

[0040] Furthermore, anti-slip ridges (not shown in the figure) are provided between adjacent finger grooves 220. The anti-slip ridges can be made of silicone or rubber to increase friction when gripping and prevent the hand from slipping due to sweat or excessive force. This design further ensures the stability of the grip and prevents the grip body 200 from slipping in situations where the pregnant woman is in severe pain, which could lead to the loss or inaccuracy of pain assessment parameters.

[0041] As a typical implementation method, the raised texture is arranged in a wave-like pattern with spacing between the lines, which ensures sufficient friction while facilitating cleaning and disinfection.

[0042] The soft area 210 is equipped with a pressure sensing module. In a typical implementation, the module consists of an array of multiple thin-film pressure sensors, which are evenly distributed on the force-bearing surface of the soft area 210. This module can comprehensively detect the pressure distribution applied to the soft area 210 by the user's gripping action.

[0043] Furthermore, the gripping body 200 is equipped with a fixing component 500, such as... Figure 4 As shown, the holding body 200 is fixed to the user's hand, wrist or arm by the fixing component 500 to prevent the device from falling or shifting due to hand fatigue or other reasons during childbirth.

[0044] The fixing component 500 includes an adjustable strap 510, the length of which is adjustable via a sliding rail buckle 520. The two ends of the strap are detachably connected; for example, a Velcro fastening area 530 is provided at the end of the strap for easy fixation after fine-tuning. Adhesive or magnetic connections are also acceptable.

[0045] The control center uses an embedded microprocessor integrated inside the grip body 200 and connects to various sensors via data cables. Based on a preset pain assessment algorithm, it can process pressure data in real time and calculate the current pain level.

[0046] Specifically, for example, during a data collection period, say 5 seconds, the pressure sensing module detects pressure data, which, after being aggregated by the control center, presents the following:

[0047]

[0048] Based on a pre-defined mapping scale between pressure values ​​and pain levels:

[0049] For example, 0-5N: Level 1-3 (mild pain)

[0050] 5-15N: Grade 4-6 (moderate pain)

[0051] 15-30N: Grade 7-9 (severe pain)

[0052] 30N: Level 10 (Extreme pain).

[0053] The corresponding pain assessment results are obtained, for example:

[0054] F_max = 8.2N → falls within the 5-15N range

[0055] F_avg=4.7N → Approaching the mild pain threshold

[0056] Assessment result: Level 4, early stage of moderate pain.

[0057] The control center generates a report based on the above evaluation results and sends it to the feedback output module for output.

[0058] The feedback output module includes a display screen (not shown in the figure).

[0059] The display screen can be embedded in the upper surface of the area of ​​the grip body 200 where the soft area 210 is not provided.

[0060] Alternatively, the display screen can be set up independently of the gripping body 200, and connected to the gripping body 200 wirelessly for convenient remote monitoring by medical staff.

[0061] The feedback output module includes at least one LED light 300 disposed on the surface of the grip body 200, such as... Figure 3 As shown.

[0062] For example, a set of LED beads is installed on the top of the grip body 200, each set containing red, yellow, and green LEDs. The control center controls the color display of the LED beads according to the assessment results. For example, levels 1-3 are green (mild pain), levels 4-6 are yellow (moderate pain), levels 7-9 are orange (severe pain), and level 10 is red (the color change provides visual feedback, helping doctors to intuitively and quickly understand the pain situation).

[0063] The feedback output module includes a vibration motor installed within the grip body 200. When the pregnant woman's pain reaches a severe or extreme level, the control center activates the vibration motor, causing the grip body 200 to vibrate continuously as one form of alarm notification to medical personnel. For example, two eccentric vibration motors are symmetrically installed inside the grip body 200, located on either side of the soft area 210.

[0064] It also includes a sound acquisition module 400 for collecting the pregnant woman's voice data; for example, a microphone set on the grip body 200, such as one that can be set on the top of the grip body 200. Figure 3 As shown, or it can be placed at the bottom of the grip body 200.

[0065] After the control center performs noise reduction and gain processing on the received sound data, it extracts key features, including but not limited to sound frequency, sound decibels, duration, and interval period.

[0066] Higher sound frequencies, higher decibel levels, longer durations, and shorter intervals may indicate more persistent and intense pain, and a higher degree of pain. Conversely, lower frequencies may indicate that the pain is more brief and less severe.

[0067] Sudden changes in volume can also reflect dramatic changes in pain. For example, a sudden scream or howl, accompanied by changes in pressure-sensing data, can help control centers determine the intensity of the pain.

[0068] Based on the preset judgment criteria, each feature is analyzed and evaluated one by one. Finally, the scores of each item are weighted and calculated, the scores are summarized, and the corresponding pain results are obtained according to the mapping relationship table.

[0069] Combining pressure and sound data for analysis can help obtain more accurate pain assessment results. For example, if the sound data shows a high-decibel scream and the pressure sensing module detects a large pressure change, it can be assessed as "severe pain" or "extreme pain" according to the mapping scale.

[0070] Optionally, two gripping bodies 200 are provided, one of which is a right-hand gripping body 200 designed for right-hand gripping habits, and the other is a left-hand gripping body 200 designed for left-hand gripping habits. In practice, pregnant women can hold the body with both hands. The control center collects the pressure data and sound data collected by the right-hand gripping body 200 and the left-hand gripping body 200 respectively for subsequent analysis and processing.

All technical, scientific, or other terms shall be interpreted as understood by one of those skilled in the art, unless defined as such. Public terms found in dictionaries should not be interpreted in an overly idealistic or impractical manner in the context of the relevant technical documentation, unless expressly defined as such in this disclosure.
