Description

Technical Field

[0001] This invention relates to the field of fetal heart rate monitoring auxiliary equipment technology, specifically to a dedicated device for an ultrasonic fetal heart rate monitoring system. Background Technology

[0002] In obstetric clinical practice, the ultrasound fetal heart rate monitor is an indispensable core device for prenatal examinations. It is mainly used to monitor fetal heart rate and assess the fetal health status in utero. During the examination, it needs to be frequently accessed and placed, and the appropriate placement directly affects the efficiency of the examination, the safety of medical procedures, and the pregnant woman's experience. Currently, there are two main placement methods for ultrasound fetal heart rate monitors in obstetric examination rooms, both of which have significant technical shortcomings and fail to meet the actual needs of clinical practice. The first method is to place it directly on the surface of the examination bed. Since obstetric examination beds need to provide ample lying space for pregnant women, the available space for examination and treatment is limited. Placing the ultrasound fetal heart rate monitor directly on it further occupies this limited space, interferes with the workflow of medical staff, and leads to inconvenience during the prenatal examination.

[0003] Meanwhile, the examination bed may shake during the examination due to the pregnant woman turning over or the medical staff touching it, causing the ultrasound fetal heart rate monitor to shift or even slip off. Since the pregnant woman's abdomen is protruding, a slipping device could easily cause injury, posing a serious safety hazard. Furthermore, the ultrasound fetal heart rate monitor is in direct contact with the examination bed surface, easily accumulating dust, stains, and debris from the pregnant woman's body, increasing the difficulty of cleaning and potentially causing cross-contamination, thus increasing the pressure on infection control. The second placement method is on a treatment cart. Treatment carts in obstetrics clinics typically need to carry various medical consumables such as coupling gel, disinfectant wipes, and gloves, making space resources limited. When placed on such carts, the ultrasound fetal heart rate monitor is often obstructed by the stacks of consumables, requiring medical staff to clear away the consumables to access the device, which is extremely inconvenient. Furthermore, during the diagnosis and treatment process, medical staff need to repeatedly move between the examination bed and the treatment cart to retrieve and place the ultrasound fetal heart rate monitor and related consumables. This not only increases the workload of medical staff but also significantly prolongs the treatment time for a single pregnant woman, reducing outpatient efficiency. Especially during peak hours, it can easily cause congestion in the examination room and affect the overall treatment order. Neither of the above two placement methods can simultaneously ensure the safety of equipment placement, ease of use, and efficient utilization of examination room space. This has long caused many problems for the daily work of medical staff and also affected the comfort and safety of pregnant women during prenatal checkups. Therefore, there is an urgent need for a technical solution for the placement of ultrasound fetal heart rate monitors that can solve the above-mentioned technical defects. Summary of the Invention

[0004] This invention discloses a dedicated device for an ultrasonic fetal heart rate monitor, aiming to address the technical shortcomings of existing ultrasonic fetal heart rate monitor placement methods in obstetric clinics, such as insufficient safety, inconvenience in access, and low space utilization.

The buckle 2-2 is fixedly connected to both ends of the canvas strap 2-1, and the strap can be opened and closed and fixed through the buckle. The coupling agent placement bracket 3 is used to store the coupling agent with the device, including a protrusion 3-1, a back frame 3-2, a retaining ring 3-3, and a coupling agent holder. The coupling agent bottle 3-4 and the back frame 3-2 are fixed to the outside of the protrusion 3-1. Two retaining rings 3-3 are fixed to the front and rear positions of the outside of the back frame 3-2 respectively. The coupling agent bottle 3-4 is snapped into the inside of the retaining rings 3-3 to facilitate the convenient use and storage of the coupling agent. The ultrasonic probe placement bracket 4 is used for the standardized storage of the ultrasonic probe 1-2. It includes a fixing block 4-1 and a slot 4-2. The slot 4-2 is fixed to the outside of the fixing block 4-1 for snapping and placing the ultrasonic probe 1-2. The hanging suction cup 5 is used for the wall-mounted placement of the ultrasonic fetal sound instrument 1. It includes a support arm 5-1 and a rubber suction cup 5-3. The rubber suction cup 5-3 is fixed to the left and right ends of the support arm 5-1 to achieve vertical fixation of the device through adsorption.

[0006] Based on the above technical solutions, the present invention further provides the following preferred technical solutions to optimize the structural rationality and usability of the device:

[0007] Preferably, the outer surface of the middle section of the canvas strap 2-1 is fixedly connected to the front and rear areas of the bottom surface of the body 1-1, so that the strap mechanism 2 and the body 1-1 form a stable connection, ensuring the stability of the equipment during carrying.

[0008] Preferably, the buckles 2-2 are interlocked to secure the canvas strap 2-1 to the forearm or upper arm of the medical staff, adapting to the mobile operation scenarios of medical staff, eliminating the need to find additional places to place the equipment, and improving the convenience of diagnosis and treatment.

[0009] Preferably, the side of the protrusion 3-1 away from the back frame 3-2 is fixedly connected to the left side wall of the body 1-1, so that the coupling agent placement bracket 3 and the body 1-1 form an integrated layout, reducing space occupation;

[0010] Preferably, the retaining ring 3-3 is provided with an opening on the side away from the back frame 3-2 for inserting and engaging the coupling agent bottle 3-4, which facilitates the quick insertion and removal of the coupling agent bottle 3-4 and simplifies the diagnostic and treatment preparation process;

[0011] Preferably, the side wall of the fixing block 4-1 away from the slot 4-2 is fixedly connected to the right side wall of the body 1-1, so that the ultrasonic probe placement bracket 4 and the body 1-1 form a stable integration, ensuring the reliability of the ultrasonic probe 1-2 storage process.

[0012] Preferably, the slot 4-2 is provided with a slot for the ultrasonic probe 1-2 to move back and forth and be inserted, and the ultrasonic wire bundle 1-3 passes through the slot 4-2 from front to back, which facilitates the flexible insertion and removal of the ultrasonic probe 1-2, and avoids the tangling and pulling of the ultrasonic wire bundle 1-3, thus protecting the integrity of the wire bundle structure.

[0013] Preferably, the side of the connecting plate 5-2 away from the support arm 5-1 is fixedly connected to the front side wall of the body 1-1, so that the hanging suction cup 5 and the body 1-1 form a stable connection, ensuring the stability of the wall-mounted placement;

[0014] Preferably, the end face of the rubber suction cup 5-3 away from the support arm 5-1 is adsorbed and connected to the wall surface, providing the ultrasonic fetal sound instrument 1 with a placement option outside the horizontal space, further optimizing the utilization rate of the examination room space;

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described below are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In order to provide a clearer explanation and description of the technical solutions and implementation methods of the present invention, the following describes specific embodiments that implement the preferred technical solutions of the present invention.

[0028] The following detailed description of the device is based on a specific embodiment. This embodiment is a specific application of a dedicated ultrasonic fetal heart rate monitor. Its overall structure is designed to solve the problem of placing ultrasonic fetal heart rate monitors in obstetric clinics. Through multi-structure integration and optimization, it achieves safe, convenient, and efficient space utilization for equipment placement. The connection and layout of each component form a complete technical support. The specific structure is as follows: The ultrasonic fetal heart rate monitor 1 is the core diagnostic component. Its main body is the body 1-1. The ultrasonic transmission end of the body 1-1 is fixedly connected to the ultrasonic cable 1-3. The end of the ultrasonic cable 1-3 is correspondingly connected to the ultrasonic probe 1-2 to achieve stable transmission of ultrasonic signals and meet the basic functional requirements of fetal heart rate detection. To accommodate the mobile operation scenarios of medical staff, two sets of strapping mechanisms 2 are integrated into the front and rear areas of the bottom surface of the body 1-1, respectively. Each set of strapping mechanisms 2 consists of a canvas strap 2-1 and a buckle 2-2. The outer surface of the middle section of the canvas strap 2-1 is fixed to the front and rear areas of the bottom surface of the body 1-1. Both ends of the canvas strap 2-1 are fixedly connected to the buckle 2-2. The two buckles 2-2 can be inserted and cooperate with each other. Through the cooperation of the two sets of strapping mechanisms 2, the ultrasound fetal sound instrument 1 can be strapped to the forearm or upper arm of the medical staff, avoiding the equipment being placed randomly during the diagnosis and treatment process and reducing the space occupied on the examination bed or treatment cart.

[0029] To enable the coupling agent to be carried with the device and avoid the stacking of consumables and equipment, the coupling agent placement bracket 3 is fixed to the left side wall of the body 1-1. The coupling agent placement bracket 3 consists of a protrusion 3-1, a back frame 3-2, a retaining ring 3-3, and a coupling agent bottle 3-4. The side of the protrusion 3-1 away from the back frame 3-2 is fixed to the left side wall of the body 1-1, and the other side of the protrusion 3-1 is fixedly connected to the back frame 3-2. A retaining ring 3-3 is fixed at the front and rear positions of the outer side of the back frame 3-2. Both retaining rings 3-3 have an opening on the side away from the back frame 3-2. The coupling agent bottle 3-4 is inserted through the opening and locked inside the retaining ring 3-3, so that the coupling agent can be carried synchronously with the ultrasound fetal sound instrument 1. There is no need to go back and forth to retrieve it during the consultation, which shortens the preparation time for diagnosis and treatment. To ensure proper placement of the ultrasound probe 1-2 and prevent contamination or damage caused by haphazard placement, the ultrasound probe placement bracket 4 is fixed to the right side wall of the body 1-1. The ultrasound probe placement bracket 4 consists of a fixing block 4-1 and a slot 4-2. The side of the fixing block 4-1 away from the slot 4-2 is fixedly connected to the right side wall of the body 1-1. The slot 4-2 is fixed to the outside of the fixing block 4-1. The slot 4-2 has a locking opening inside, through which the ultrasound probe 1-2 can move back and forth and be inserted into the slot 4-2. At the same time, the ultrasound cable 1-3 passes through the slot 4-2 from front to back, achieving a reasonable arrangement of the ultrasound cable 1-3 when the ultrasound probe 1-2 is placed, avoiding tangling or pulling of the cable.

[0030] To provide a wall-mounted placement option and further save space on the examination room floor and table, a hanging suction cup 5 is integrated into the front of the device 1-1. The hanging suction cup 5 consists of a support arm 5-1, a connecting plate 5-2, and a rubber suction cup 5-3. The side of the connecting plate 5-2 away from the support arm 5-1 is fixedly connected to the front side wall of the device 1-1. One end of the support arm 5-1 is fixed to the connecting plate 5-2, and both ends of the support arm 5-1 are fixedly connected to the rubber suction cup 5-3. The end face of the rubber suction cup 5-3 away from the support arm 5-1 can be adsorbed onto the wall surface, achieving vertical hanging placement of the ultrasound fetal heart rate monitor 1 without occupying horizontal examination space. To accommodate temporary placement beside the examination bed, four magnets are embedded and fixed at the four corners of the bottom surface of the device 1-1. Through the magnetic attraction of the four magnets, the ultrasound fetal heart rate monitor 1 can be adsorbed onto the side of the examination bed in the obstetrics examination room, avoiding direct placement of the equipment on the bed or treatment cart, reducing the risk of equipment displacement and slippage, and lowering the probability of equipment contamination. This embodiment integrates and coordinates the above structures to provide three placement methods for the ultrasound fetal heart rate monitor 1: arm restraint carrying, wall hanging, and magnetic attachment beside the examination bed. Medical staff can flexibly choose according to the diagnosis and treatment scenario, without having to place the equipment on the examination bed or stack it on the treatment cart, effectively saving diagnosis and treatment space, optimizing the operation flow of medical staff, avoiding the risk of bumping or falling of the equipment to pregnant women, reducing the possibility of the equipment getting dirty, and reducing the pressure of hospital infection control.

[0031] Meanwhile, the coupling agent is carried with the device through the coupling agent placement bracket 3, and the ultrasound probes 1-2 are placed in a standardized manner through the ultrasound probe placement bracket 4. During the consultation, there is no need to go back and forth to retrieve and place the device and consumables, which shortens the time spent on a single consultation, improves the efficiency of outpatient consultation, and takes into account the safety and convenience of device placement and the utilization rate of consultation room space. It solves many problems caused by traditional placement methods to the daily work of medical staff and the prenatal check-up experience of pregnant women. In this embodiment, the connection relationship of each component forms a complete technical solution. The synergistic effect of each structure effectively addresses the core pain point of placing an ultrasound fetal heart rate monitor in an obstetrics and gynecology clinic. The strap mechanism 2 is adapted to mobile medical scenarios, allowing medical staff to carry the device with them during consultations without having to search for a temporary placement location. The integration of the coupling agent placement bracket 3 and the ultrasound probe placement bracket 4 achieves an integrated layout of the device and its supporting consumables and components, reducing the space occupation and inconvenience of storing consumables separately. The hanging suction cup 5 and the bottom magnet provide two fixed placement methods: wall-mounted and bedside, further expanding the device placement scenarios and avoiding various drawbacks of traditional placement methods. The layout and connection of each structure meet the needs of the obstetrics and gynecology clinic. The overall technical solution can be directly applied to clinical diagnosis and treatment, solving the problem that traditional placement methods cannot balance safety, convenience, and space utilization.

[0032] The workflow of this technical solution is as follows: After receiving a pregnant woman, medical staff select the placement method of the ultrasound fetal heart rate monitor 1 according to the diagnosis and treatment scenario and operational needs of the obstetrics clinic. If movement is required, the ultrasound fetal heart rate monitor 1 can be secured to the forearm or upper arm by interlocking the buckles 2-2 of the two sets of strapping mechanisms 2. If movement is not required, the ultrasound fetal heart rate monitor 1 can be attached to the side of the examination bed by the magnets at the four corners of the bottom of the body 1-1, or it can be vertically suspended by attaching to the wall through the rubber suction cup 5-3 of the hanging suction cup 5; the diagnosis and treatment accuracy During the preparation phase, medical staff remove the ultrasound probe 1-2 from the slot 4-2 of the ultrasound probe placement bracket 4. The ultrasound cable 1-3 extends from the slot 4-2 along with the ultrasound probe 1-2. Simultaneously, the coupling agent bottle 3-4 is removed from the retaining ring 3-3 of the coupling agent placement bracket 3. After applying the coupling agent, the coupling agent bottle 3-4 is inserted back into the retaining ring 3-3 through the opening and secured. Subsequently, the medical staff hold the ultrasound probe 1-2 and perform fetal heart rate detection on the pregnant woman's abdomen. The ultrasound signal is transmitted through the ultrasound probe 1-2 to the ultrasound cable. 1-3, and then the ultrasound signal is transmitted from the ultrasound bundle 1-3 to the machine body 1-1. The machine body 1-1 processes the ultrasound signal and presents the detection results. During the detection process, if the operating position needs to be adjusted, the ultrasound fetal heart rate monitor 1, which is attached to the arm, can move synchronously with the medical staff's movements without the need for temporary placement. If the operation needs to be paused, the ultrasound probe 1-2 can be temporarily inserted into the slot 4-2 to avoid random placement. After the fetal heart rate detection is completed, the medical staff cleans the ultrasound probe 1-2. After cleaning, the ultrasound probe 1-2 is inserted into the slot 4-2. -2 The buckle is inserted and placed back and forth. The ultrasound cable 1-3 is simultaneously passed through the slot 4-2 and stored. Then, confirm that the coupling agent bottle 3-4 is securely locked in the ring 3-3. If the ultrasound fetal heart rate monitor 1 was previously placed by arm restraint, the buckle 2-2 can be released to remove the device. Depending on the space of the examination room, it can be attached to the side of the examination bed or hung on the wall to complete the use and storage of the device in the entire diagnosis and treatment process. When receiving patients later, the ultrasound fetal heart rate monitor 1 can be directly taken from the corresponding placement position, and the above process can be repeated to carry out the diagnosis and treatment operation.
