Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a medical intelligent headboard protractor. Background Art

[0002] In enteral nutrition support treatment, in order to utilize gravity to reduce gastric content reflux and prevent complications such as aspiration pneumonia, patients usually need to maintain a body position with the head of the bed elevated by 30 - 45 degrees. This body position can effectively reduce the pressure difference between the esophagus and the stomach and promote the delivery of nutrient solution to the small intestine, which is crucial for ensuring patient safety. However, most of the mechanical angle measurement devices currently used in clinics are fixedly installed on the side metal frame of the headboard of the hospital bed that can be shaken up. This installation method results in the separation of the angle adjustment and reading operation spaces. The nursing staff needs to first walk around to the end of the bed, adjust the headboard angle by shaking the handle, and then return to the bedside to visually check the scale area to confirm whether the angle meets the requirements. This operation mode is not only cumbersome, increasing the workload of the nursing staff, but also prone to angle calibration deviation because the angle adjustment and angle reading are not performed at the same position. Especially during night monitoring or in emergency situations, with limited light conditions or hasty operations, the nursing staff may overlook the precise monitoring of the angle due to line of sight obstruction or negligence, thus increasing the potential risk of aspiration for patients. In view of the above problems, the existing technology urgently needs to be improved. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0030] In the field of medical care, especially when caring for patients receiving enteral nutrition support treatment, precisely controlling the head angle of the hospital bed is of crucial importance. Although traditional mechanical protractors can measure angles, their operation methods have inherent limitations. Nursing staff often need to travel back and forth between the foot of the bed and the bedside for angle adjustment and reading confirmation. The operation is cumbersome and prone to errors. Especially at night or in emergency situations, it is difficult to ensure the accuracy and timeliness of angle monitoring, which undoubtedly increases the risk of aspiration and other problems for patients. To overcome the deficiencies of the existing technology and provide a device that can more conveniently and accurately monitor the head angle of the bed, the present utility model proposes a medical intelligent headboard protractor. This protractor can not only accurately measure the head angle of the bed but also timely remind the nursing staff through voice broadcast, thus effectively improving the nursing efficiency and patient safety.

[0031] To facilitate the understanding of the technical solution of the present utility model, key terms involved in the present utility model are first explained. The medical intelligent headboard protractor, as the name implies, is an intelligent device applied in a medical environment, especially at the head of the hospital bed, for measuring the elevation angle of the head of the bed. This protractor aims to provide an accurate and convenient means of angle monitoring to assist medical staff in ensuring that patients are in the best treatment position.

[0032] As Figures 1 to 4 shown, the medical intelligent headboard protractor of the present utility model mainly consists of components such as a base 1, a scale indicator board, a movable slot 8, a pointer 7, a first terminal 9, a second terminal 10, an elastic member, a second joint 13, a third joint 14, a first joint 12, a housing 2, a speaker 16, and a power supply mechanism. Among them, the base 1 is designed as a component for mounting on the hospital bed frame, and it can adopt various fixing methods. The scale indicator board is arranged on the side wall of the base 1, and multiple indicator areas are divided on it, including a first indicator area 3, a second indicator area 4, a third indicator area 5, and a fourth indicator area 6. These indicator areas respectively correspond to different head angle ranges. The movable slot 8 is penetrated and opened on the scale indicator board to provide a movement space for the electrical contact mechanism of the protractor. The pointer 7 is rotatably arranged on the top of the base 1, and due to the action of gravity, the pointer 7 always remains vertically downward. When the head angle changes, the angle of the pointer 7 relative to the scale indicator board also changes accordingly, thereby indicating the current head angle.

[0033] In order to achieve the intelligent voice prompt function for the headboard angle, the utility model ingeniously designs an electrical contact mechanism. Specifically, the first terminal 9 and the second terminal 10 are connected to the pointer 7, and an elastic member is provided between the first terminal 9 and the second terminal 10. The elastic member can be a spring 19, or a structure composed of a spring 19 and a spring gasket 11. The function of the elastic member is to provide a continuous thrust for the first terminal 9 and the second terminal 10 to ensure that they always maintain reliable electrical contact with the inner wall of the movable slot 8. The second connector 13 and the third connector 14 are used as fixed contacts and are preset at specific angular positions in the movable slot 8. For example, the second connector 13 can be set at a position in the movable slot 8 corresponding to between the first indicating area 3 and the second indicating area 4, representing an angular threshold of 30 degrees or 45 degrees; the third connector 14 can be set at a position in the movable slot 8 corresponding to between the third indicating area 5 and the fourth indicating area 6, representing other angular thresholds such as 60 degrees. The first connector 12 is also provided on the inner wall of the movable slot 8 and is electrically connected to the fixed contact as part of the circuit. The housing 2 is fixedly connected to the top of the base 1 to protect the internal precision components. The speaker 16 is used for voice broadcast to timely transmit the headboard angle information to the caregiver. The power supply mechanism is arranged inside the housing 2 to provide power drive for the entire medical intelligent headboard protractor. The power supply mechanism can be powered by a storage battery 15, and preferably a rechargeable battery, to extend the service life and reduce the maintenance cost.

[0034] Thus, when the power supply mechanism powers the medical intelligent headboard protractor and the headboard angle changes, the first terminal 9 and the second terminal 10 connected to the pointer 7 will move together with the pointer 7 in the movable slot 8. When the pointer 7 rotates to a specific angular range, such as reaching 30 degrees or 45 degrees, the first terminal 9 will come into contact with the second connector 13 or the third connector 14 at the preset position under the thrust of the elastic member, so that the first connector 12, the second terminal 10, the elastic member, the first terminal 9, and the corresponding second connector 13 or third connector 14 form a closed circuit. Once the closed circuit is formed, it will trigger the speaker 16 to emit a voice broadcast, such as broadcasting prompt messages like "The headboard has been raised by 30 degrees" or "The headboard has been raised by 45 degrees", so as to timely remind the caregiver that the current headboard angle has reached the preset key threshold.

[0035] Compared with the mechanical protractor in the prior art, the medical intelligent headboard protractor of the present utility model has significant advantages. The traditional mechanical protractor can only provide scale indication, and nursing staff must visually check to obtain the angle information, which is cumbersome to operate and prone to visual errors. However, the present utility model innovatively introduces electrical contact and voice broadcast technologies to achieve automatic monitoring of the headboard angle and voice prompts, eliminating the need for nursing staff to repeatedly visually confirm, greatly simplifying the operation process, and improving the efficiency and accuracy of angle monitoring. Especially at night or in emergency situations, the advantage of the voice prompt function is more prominent, which can effectively avoid monitoring negligence caused by insufficient light or hasty operation, thus better ensuring patient safety.

[0036] In summary, the medical intelligent headboard protractor of the present utility model effectively solves the problems of inconvenient operation and easy deviation existing in the prior art through ingenious structural design and application of intelligent technologies, providing a more efficient, accurate, and safe headboard angle monitoring tool for clinical nursing work, and having important clinical application value.

[0037] During actual use, similar to the above-mentioned second joint 13 or third joint 14, a third joint can be added as a temporary contact in the first indicating area 3, and the position of the temporary contact is set at a certain position below 30 degrees according to the actual situation. When the first terminal 9 touches the third joint, the touch-activated speaker 16 emits a voice broadcast, and the content of the voice broadcast is to remind the nursing staff to rock the headboard angle back later or change it to the required angle.

[0038] As an implementation manner of the present utility model, a magnet 18 is provided on the base 1 for adsorbing the medical intelligent headboard protractor on the bed frame of the hospital bed.

[0039] Specifically, the magnet 18 can be embedded or fixed on the bottom surface of the base 1, so that the bottom of the base 1 has magnetic adsorption ability. When installing the medical intelligent headboard protractor, just bring the base 1 close to the iron bed frame of the hospital bed, and the magnetic force generated by the magnet 18 can firmly adsorb the protractor on the bed frame without using screws, clamps or other additional fixing tools.

[0040] Thus, by providing the magnet 18 on the base 1, the medical intelligent headboard protractor of the present utility model realizes a magnetic adsorption fixing method. Compared with the traditional bolt fixing or clamping fixing methods, the magnetic adsorption fixing does not require complex installation steps and can be completed simply by approaching, greatly improving the convenience of installation and disassembly. At the same time, the magnetic attraction can provide sufficient fixing strength to ensure the stability of the protractor during use, avoiding displacement or falling off due to accidental collision or vibration, thereby ensuring the accuracy and reliability of angle measurement and providing a more convenient and efficient headboard angle monitoring tool for medical staff.

[0041] Furthermore, the present application also proposes that the right end of the fourth indication area 6 on the scale indicator board be used as a reference when it is parallel to the bedside.

[0042] To ensure that the medical intelligent headboard goniometer can accurately measure the headboard angle during actual use, this embodiment further optimizes the scale indication area on the scale indicator board. The design purpose of the fourth indication area 6 is to provide a simple and reliable reference for the initial installation of the goniometer. Specifically, when installing the medical intelligent headboard goniometer, the caregiver can roughly align the right end of the fourth indication area 6 with the bedside of the hospital bed and keep it parallel.

[0043] As an implementation manner of the present utility model, the angle indicated by the first indication area 3 is 30 degrees or 45 degrees, and the angle indicated by the second indication area 4 is 60 degrees.

[0044] As an implementation manner of the present utility model, the elastic member includes two spring washers 11. The two spring washers 11 are respectively fixed at the ends of the opposite surfaces of the first terminal 9 and the second terminal 10. A spring 19 is fixedly connected between the two spring washers 11. The spring 19 is used to provide a thrust force to ensure that the first terminal 9 and the second terminal 10 remain in electrical contact with the inner wall of the movable slot 8.

[0045] The spring washer 11 plays an important role here. First of all, the spring washer 11 can increase the contact area between the terminal and the spring 19, so that the thrust force of the spring 19 can be more evenly distributed on the terminal, avoiding stress concentration and improving the reliability of the connection. Secondly, the spring washer 11 can play a certain buffering role, absorbing vibrations and impacts, and protecting the spring 19 and the terminal from damage. The spring 19, as the core elastic element, its main function is to provide a continuous thrust force to ensure that the first terminal 9 and the second terminal 10 always remain in close electrical contact with the inner wall of the movable slot 8.

[0046] Thus, by adopting the elastic member composed of the spring washer 11 and the spring 19, the electrical contact mechanism of the medical intelligent headboard goniometer of the present utility model has been further improved in terms of reliability and stability.

[0047] As an implementation manner of the present utility model, the power supply mechanism includes a storage battery 15. The storage battery 15 is fixedly installed inside the housing 2 and is used to supply power to the medical intelligent headboard goniometer.

[0048] As an implementation manner of the present utility model, the storage battery 15 is a rechargeable battery.

[0049] In order to achieve autonomous power supply for the medical intelligent bedside goniometer, enabling it to work independently and provide continuous voice prompt function, in this embodiment, the power supply mechanism is specifically embodied as including a storage battery 15. The storage battery 15 is fixedly installed inside the housing 2 and serves as the energy source for the entire medical intelligent bedside goniometer, providing necessary power support for components such as the speaker 16 and the electrical contact mechanism. The storage battery 15 in the power supply mechanism is preferably a rechargeable battery. As the name implies, a rechargeable battery can be repeatedly charged and used. Compared with disposable batteries, its greatest advantage lies in its ability to be recycled, reducing the frequency of battery replacement, lowering the long-term use cost, and reducing the environmental pollution caused by waste batteries.

[0050] As an implementation manner of the present utility model, the power supply mechanism further includes a switch 17 provided on the top of the base 1 for controlling the on-off of the power supply of the medical intelligent bedside goniometer.

[0051] In order to further improve the usability and energy-saving performance of the medical intelligent bedside goniometer, an important component, the switch 17, is added to the power supply mechanism in this embodiment. The switch 17 is provided on the top of the base 1, and this position is convenient for the nursing staff to reach during operation. The main function of the switch 17 is to control the on-off of the power supply of the medical intelligent bedside goniometer, that is, to control whether the entire device is in a working state.

[0052] As an implementation manner of the present utility model, the speaker 16 is a voice speaker.

[0053] In order to make the prompt information of the medical intelligent bedside goniometer more intuitive, clear, and easy for the nursing staff to receive and understand, in this embodiment, the speaker 16 is specifically designated as a voice speaker. A voice speaker is an electroacoustic device that can emit human voice signals. Compared with a buzzer or an indicator light that can only emit simple sound signals, a voice speaker can transmit richer and more specific information content.

[0054] The function of the voice speaker here is to directly transmit the head-of-bed angle information to the nursing staff in the form of voice broadcast. When the head-of-bed angle reaches the preset key threshold, instead of emitting a monotonous beeping sound or flashing light, the medical intelligent head-of-bed goniometer clearly broadcasts the current head-of-bed angle value or status through the voice speaker, such as "The head of the bed has been raised by 30 degrees", "The head of the bed has been raised by 45 degrees", etc. This voice prompt method has significant advantages. First of all, voice information has more information content than sound signals or visual signals, and can directly express the angle value or status without the need for nursing staff to make additional interpretations or judgments. Secondly, voice prompts have stronger penetration and directivity. Even in a noisy medical environment, or when the nursing staff's line of sight is not directly focused on the goniometer, the voice prompt information can be clearly received. In addition, voice prompts do not require the nursing staff to shift their line of sight. Especially at night or in a dimly lit environment, the advantages of voice prompts are more obvious, which can effectively avoid misjudgment or negligence caused by visual obstacles. As an optional implementation method, the voice speaker can pre-record voice prompts for various angle states, such as 30 degrees, 45 degrees, 60 degrees, etc., and trigger the playback of the corresponding voice information according to the actual angle monitoring results. The content of the voice can be customized as needed, such as using different languages, intonations or volumes to adapt to different usage scenarios and user needs.

[0055] Thus, by adopting the voice speaker as the prompt output device, the medical intelligent head-of-bed goniometer of the present utility model realizes a more intuitive, clear and efficient angle information transmission method. Compared with the traditional sound and light prompt method, voice prompts can provide richer information content, stronger environmental adaptability, and more convenient information acquisition methods, significantly improving the work efficiency of nursing staff and the accuracy of angle monitoring, and providing a more reliable guarantee for the safe nursing of patients.

[0056] The working principle of the present utility model:

[0057] The medical intelligent head angle measurer is adsorbed on iron components such as the hospital bed frame through the magnet 18 on the base 1, and the position is adjusted so that the right end of the fourth indicating area 6 on the housing 2 is roughly parallel to the edge of the bed as a reference. When the head angle of the hospital bed is adjusted, the pointer 7 in the housing 2 always points downward due to the gravity, and its angle changes relative to the scale indicating plate. The first terminal 9 and the second terminal 10 connected to the pointer 7 are always in electrical contact with the inner wall of the movable groove 8 under the thrust of the spring 19 and move in the movable groove 8 together with the pointer 7. When the pointer 7 rotates to a specific angle range, when the first terminal 9 contacts the second joint 13 or the third joint 14, the first joint 12, the second terminal 10, the elastic member, the first terminal 9 and the corresponding second joint 13 or third joint 14 form a closed circuit, triggering the sounding of the speaker 16 to give a voice broadcast, indicating that the current head angle has reached a specific range. This closed circuit triggers the internal speaker 16 to give a voice broadcast under the condition that the switch 17 is turned on and the battery 15 supplies power, indicating that the current head angle has reached the preset angle, so as to remind the nursing staff to pay attention to the risk of patient reflux.

[0058] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model.
