Description

Technical Field

[0001] The present invention relates to the technical field of nursing beds, in particular to a medical hyperbaric oxygen chamber nursing bed. Background Art

[0002] A medical hyperbaric oxygen chamber is a specialized medical device used for hyperbaric oxygen therapy. It allows patients to inhale pure or highly concentrated oxygen at a pressure higher than normal atmospheric pressure (one standard atmosphere). By increasing the ambient pressure, the dissolved oxygen content in the blood is significantly elevated, increasing both the partial pressure of oxygen and the diffusion distance of oxygen. This improves hypoxia in tissues and organs, promotes cellular aerobic metabolism, and ultimately, plays a therapeutic role.

[0003] Most medical hyperbaric oxygen chambers (especially those used to treat critically ill or bedridden patients) are equipped with nursing beds for patients who cannot sit up to lie flat during treatment. During hyperbaric oxygen treatment, the patient lies on the nursing bed inside the hyperbaric oxygen chamber, while medical staff outside the chamber control parameters such as pressure and oxygen concentration, and communicate with the patient through the intercom system (such as guiding breathing coordination and asking about discomfort). Family members need to wait in a designated area. If the patient needs to communicate, it is generally transferred through medical staff outside the chamber, or directly through the intercom system under some permitted circumstances (this must comply with hospital regulations).

[0004] Hyperbaric oxygen chambers are sealed chambers (typically cylindrical metal structures), and medical staff can only observe patients from outside via monitoring and intercom systems. Bedridden patients, lying flat on their backs, have limited range of motion and are unable to reach the chamber walls or cameras. This limits the transmission of visual signals such as facial expressions and gestures. Furthermore, during treatment, the chamber undergoes pressurization and decompression, and changes in air pressure can easily cause discomfort in the patient's middle ear (such as earache and tinnitus), impairing auditory clarity, leading to delayed two-way communication, inefficient doctor-patient communication, and even delayed emergency response, delaying treatment. Therefore, we propose a medical hyperbaric oxygen chamber nursing bed. Summary of the Invention

Bedridden patients, lying flat on their backs, have limited range of motion and are unable to move their limbs to approach the chamber walls or cameras. This limits the transmission of visual signals such as facial expressions and gestures. Furthermore, during treatment, the chamber requires pressurization and decompression, and changes in air pressure can easily cause discomfort in the patient's middle ear (e.g., earache, tinnitus), impairing auditory clarity, leading to delayed two-way communication, inefficient doctor-patient communication, and even delayed emergency response, delaying treatment opportunities.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figures 1 to 14 The present invention provides a technical solution: a medical hyperbaric oxygen chamber nursing bed, comprising a nursing bed frame 6, which is installed in the hyperbaric oxygen chamber; further comprising: a nursing bed board 7, which is installed on the surface of the nursing bed frame 6 and can rotate on the surface of the nursing bed frame 6; an alarm 1, which is installed on the surface of the nursing bed frame 6; a trigger mechanism 2, which is located between the alarm 1 and the nursing bed board 7, and the bedridden patient triggers the alarm button of the alarm 1 through the trigger mechanism 2; a judgment mechanism 4, which is connected to the trigger mechanism, and the judgment mechanism 4 judges whether the patient has accidentally touched the alarm based on the time it takes for the patient to complete a predetermined action, and controls the trigger mechanism to work after judging that it is not an accidental touch, and the trigger mechanism presses the alarm button of the alarm 1; an emergency assessment mechanism 5, which is connected to the trigger mechanism, and the emergency assessment mechanism 5 issues alarms of different sharpness based on the different amplitudes of the patient's movements.

[0042] When in use, the nursing bed frame 6 is installed in the hyperbaric oxygen chamber. The medical staff transfers the patient to be treated with hyperbaric oxygen to the nursing bed board 7 in the hyperbaric oxygen chamber and adjusts the inclination angle of the nursing bed board 7 to make the patient in a comfortable posture. The alarm 1 is installed at the head of the nursing bed frame 6. When the air pressure change in the cabin causes discomfort in the patient's middle ear (such as earache, tinnitus), so that the patient needs to call medical staff, the patient on the bed can also actively trigger the driving mechanism 3 through a pre-set action. At this time, the false touch identification mechanism 4 determines whether the patient has touched the device by mistake or needs help according to the patient's action frequency. The predetermined action is determined according to the patient's injury. For example, the patient is not physically fit. When moving, the action can be shaking the head on the bed, and the shaking of the head is used as a triggering action. If it is an accidental touch, the driving mechanism 3 does not control the triggering mechanism 2 to trigger the alarm button of the alarm 1; if it is not an accidental touch, the false touch identification mechanism 4 controls the driving mechanism 3 to work, the driving mechanism 3 controls the triggering mechanism 2 to work, and the triggering mechanism 2 actively triggers the alarm button of the alarm 1, so as to call medical staff in time to avoid the call delay causing the patient's condition to worsen, and the emergency assessment mechanism 5 can also judge the patient's urgency according to the frequency of the patient's movements, thereby issuing alarms of different sharpness, thereby transmitting information to medical staff outside the hyperbaric oxygen chamber.

[0043] The emergency assessment mechanism 5 includes a detection seat 511, and a connecting groove 50 is opened on the inner wall of the detection seat 511. The inner wall of the connecting groove 50 is slidably connected to a trapezoidal block 51. The trapezoidal block 51 is fixedly connected to a piston plate three 52 near one end of the detection seat 511. The piston plate three 52 is slidably connected to the inner wall of the connecting groove 50. The outer side of the piston plate three 52 is fixedly connected to a return spring two 53. The return spring two 53 is installed on the inner wall of the connecting groove 50. A whistle 54 is installed on the outer side of the detection seat 511. The whistle 54 is connected to the connecting groove 50. A one-way conductive part 55 is provided on the inner side of the detection seat 511. The one-way conductive part 55 is connected to the false touch identification mechanism 4.

[0044] When the patient moves his head in bed, the false touch identification mechanism 4 is triggered to work, and the false touch identification mechanism 4 drives the one-way conductive member 55 to rotate. Each rotation of the one-way conductive member 55 lifts the trapezoidal block 51 once. When the trapezoidal block 51 moves upward, it pushes the piston plate 3 52 to slide upward along the inner wall of the connecting groove 50, thereby pushing the gas in the connecting groove 50 into the whistle 54. The whistle 54 is generally made of metal, plastic or other materials, and has a reed or ball inside that can make a sound. When blowing air, the air vibrates and makes a sharp sound. When the piston plate 3 52 moves upward, it compresses the return spring 2 53. The return spring 2 53 pushes the trapezoidal block 51 to return to its original position when the trapezoidal block 51 is not subjected to the upward thrust.

[0045] If the patient's head shaking movements are long, the number of rotations of the one-way guide member 55 driven by the false touch identification mechanism 4 after each head shaking is small, and the number of piston movements of the piston plate 3 52 driven by the trapezoidal block 51 on the inner wall of the connecting groove 50 is small. Therefore, when the piston plate 3 52 moves the same distance in the connecting groove 50 each time, the number of piston movements is small. If the patient's head shaking movement is faster, the false touch identification mechanism 4 drives the one-way guide member 55 to rotate faster, the frequency of the trapezoidal block 51 lifting is higher, and the number of continuous piston movements is greater.

[0046] Each time the piston plate 52 moves, a certain amount of air will flow through the outlet end of the connecting groove 50 to the whistle 54. The more times the piston plate 52 is pumped continuously, the greater the total amount of air that passes through the whistle 54 per unit time. According to the principles of fluid mechanics, in a pipeline (here, the connection part and the internal channel of the whistle 54 can be regarded as similar to a pipeline), the greater the flow rate, the greater the flow rate is generally. As more air is squeezed out, the air flow speed will continue to accumulate, which will cause the vibration frequency of the air column in the whistle 54 to increase, and the sound will become sharper. Therefore, the more times the patient shakes his head spontaneously, the sharper the alarm sound of the whistle 54 will be, so as to help alert the surrounding caregivers and family members. In addition, when the patient shakes his head unconsciously, that is, accidentally touches the whistle, the airflow generated by one or two piston movements is not enough to cause the air in the whistle 54 to vibrate, so no sound will be emitted, or the sound will be low, so as not to affect the patient's normal rest.

[0047] The trigger mechanism 2 includes a pressing block 20, which is located outside the alarm button of the alarm 1. A plurality of plastic brackets 21 are fixedly connected to the outside of the pressing block 20. The plastic brackets 21 are L-shaped and fixed to the surface of the alarm 1. A sliding groove 22 is opened on the inner wall of the pressing block 20, and an alarm member 23 is provided on the inner wall of the sliding groove 22.

[0048] The driving mechanism 3 is connected to the pressing block 20 , and the patient actively controls the pressing block to press the alarm button of the alarm 1 through the driving mechanism 3 .

[0049] When the alarm 1 is triggered, the driving mechanism 3 pushes the pressing block 20 to move. Since the plastic bracket 21 is L-shaped and elastic, the pressing block 20 will cause the plastic bracket 21 to deform when it approaches the alarm button of the alarm 1 until the pressing block 20 triggers the alarm button of the alarm 1. The alarm 1 alerts the nurse outside the hyperbaric oxygen chamber to remind medical staff to go inside the hyperbaric oxygen chamber to check.

[0050] When the patient triggers the alarm 1, the patient is required to repeat a specific action at a fixed frequency. When the patient performs the action, the driving mechanism 3 is triggered to work, and the false touch identification mechanism 4 detects the speed of the patient's action, so as to judge whether the patient is accidentally touching it or needs to call medical staff. If it is an accidental touch, the driving mechanism 3 does not control the alarm component 23 to work, so that the alarm component 23 does not press the alarm button of the alarm 1; if it is not an accidental touch, the driving mechanism 3 controls the alarm component 23 to work, and the alarm component 23 works and triggers the alarm button of the alarm 1.

[0051] The alarm component 23 includes a trigger block 24, which is slidably connected to the inner wall of the slide groove 22. The trigger block 24 corresponds to the position of the alarm button of the alarm 1. The trigger block 24 is fixedly connected to a piston plate 25 at one end away from the alarm 1. The piston plate 25 is slidably connected to the inner wall of the slide groove 22. A return spring 26 is fixedly connected to the outer side of the piston plate 25, and the return spring 26 is fixed to the inner wall of the slide groove 22.

[0052] When the alarm element 23 is working, the driving mechanism 3 supplies air to the slide groove 22, so that the air pressure in the slide groove 22 increases. The increased air pressure pushes the piston plate 25 to slide on the inner wall of the slide groove 22. The piston plate 25 stretches the return spring 26, and the piston plate 25 pushes the trigger block 24 to move, so that the trigger block 24 partially extends out of the inner wall of the slide groove 22 and squeezes the alarm button of the alarm 1, thereby alerting the nurse outside the hyperbaric oxygen chamber.

[0053] The driving mechanism 3 includes a transmission tube 30 connected to the pressing block 20. The end of the transmission tube 30 away from the pressing block 20 is connected to a connecting box 31. The connecting box 31 is fixed on the surface of the nursing bed frame 6. The connecting box 31 is hollow. The outside of the connecting box 31 is connected to a Y-shaped conduit 32. The remaining two ends of the Y-shaped conduit 32 are respectively connected to air transmission parts 33.

[0054] When in use, the connecting box 31 is installed at the head of the bed. The connecting box 31 is hollow and its function is to inject the gas input by the Y-shaped tube 32 into the transmission tube 30. When the driving mechanism 3 is working, the patient triggers the gas delivery component 33, and the corresponding gas delivery component 33 will supply gas to the Y-shaped tube 32. The gas enters the connecting box 31 through the Y-shaped tube 32, and the gas in the connecting box 31 enters the slide 22 of the pressing block 20 through the transmission tube 30, thereby increasing the air pressure in the slide 22 to cooperate with pushing the piston plate 25 to slide on the inner wall of the slide 22.

[0055] The air transmission component 33 includes a fixing base 34 installed under the nursing bed board 7, the detection base 511 is installed on the outside of the fixing base 34, an air storage chamber 35 is opened on the inner wall of the fixing base 34, an air inlet 36 and an exhaust pipe 37 are respectively opened on the top of the air storage chamber 35, the air inlet 36 is connected to the false touch identification mechanism 4, an exhaust component 38 is installed on the outside of the exhaust pipe 37, the inner wall of the air storage chamber 35 is slidably connected to the piston plate 2 39, the end of the piston plate 2 39 away from the air inlet 36 is fixedly connected to the compression spring 310, the compression spring 310 is fixed to the inner wall of the air storage chamber 35, the outer side of the fixing base 34 is fixedly connected to the air outlet pipe 312, the air outlet pipe 312 is connected to the air storage chamber 35, the Y-shaped guide tube 32 is connected to the connecting pipe 313, and a connecting component 314 for controlling the connection state of the connecting pipe 313 and the air outlet pipe 312 is provided between the connecting pipe 313 and the air outlet pipe 312;

[0056] The exhaust component 38 includes a sealing box 311 connected to the exhaust pipe 37. The sealing box 311 is installed on the surface of the fixed seat 34. The inner wall of the sealing box 311 is slidably connected to the sealing plate 320. The outer side of the sealing plate 320 is fixedly connected to a pull rope 321. The end of the sealing plate 320 away from the pull rope 321 is fixedly connected to an elastic rope 322. The elastic rope 322 is fixed to the inner wall of the sealing box 311. The elastic limit of the elastic rope 322 determines the maximum displacement of the sealing plate 320 to prevent excessive stretching. The end of the pull rope 321 away from the sealing plate 320 passes through the sealing box 311 and is fixed to the piston plate 2 39.

[0057] When the gas delivery part 33 is working, the false touch identification mechanism 4 determines whether the patient has touched the gas by mistake according to the patient's movement frequency. When it is determined that the patient has not touched the gas by mistake, the false touch identification mechanism 4 drives the connecting part 314 to work. The connecting part 314 connects the connecting pipe 313 with the gas outlet pipe 312. As the patient continuously shakes his head, gas continuously enters the gas storage chamber 35. The gas pressure in the gas storage chamber 35 increases and pushes the piston plate 2 39 to move downward. The piston plate 2 39 drives the sealing plate 320 to move through the pull rope 321. The sealing plate 320 stretches the elastic rope 322, so that the sealing plate 320 closes the exhaust pipe 37. The patient continues to move his head, but the elastic rope 322 no longer stretches after being pulled to the maximum limit, and the position of the sealing plate 320 is restricted, so that the position of the piston plate 2 39 is also restricted by the sealing plate 320 through the stretched pull rope 321, so that the air pressure in the air storage chamber 35 begins to increase, and the gas in the air storage chamber 35 is discharged through the air outlet pipe 312. The gas discharged from the air outlet pipe 312 enters the connecting pipe 313 through the connecting piece 314, and enters the Y-shaped catheter 32 through the connecting pipe 313, so as to cooperate with the piston plate 1 25 to slide on the inner wall of the slide groove 22, thereby triggering the alarm button of the alarm 1.

[0058] When the patient stops moving his head, the reset spring 26 pulls the piston plate 25 to reset, so that the pull rope 321 is loosened, and the stretched elastic rope 322 drives the sealing plate 320 to reset, so that the exhaust pipe 37 is opened.

[0059] If the false touch identification mechanism 4 determines that the patient's action is a false touch, the piston plate 2 39 descends a short distance, and the exhaust pipe 37 is still in a connected state, so that the air storage chamber 35 will be discharged through the exhaust pipe 37, and the alarm button of the alarm 1 will not be triggered.

[0060] The connecting part 314 includes a transmission cylinder 315, which is connected to the connecting pipe 313 and the air outlet pipe 312 respectively. A rotating groove 316 is provided on the inner wall of the transmission cylinder 315, and a closed cylinder 317 is rotatably connected to the inner wall of the rotating groove 316. A connecting hole 318 is provided on the surface of the closed cylinder 317. The opening size of the connecting hole 318 is larger than the connecting diameter of the transmission cylinder 315 and the connecting pipe 313. A transmission wheel 319 is fixedly connected to the outside of the closed cylinder 317, and the transmission wheel 319 is connected to the false touch identification mechanism 4.

[0061] When the patient makes a predetermined action, such as shaking his head, the patient will trigger the false touch identification mechanism 4 to work, and the false touch identification mechanism 4 drives the transmission wheel 1 319 to rotate, and the transmission wheel 1 319 drives the sealing cylinder 317 to rotate. When the patient shakes his head for many consecutive times, as the number of times the patient shakes his head increases, the distance that the piston plate 2 39 descends increases, until the transmission wheel 1 319 drives the sealing cylinder 317 to rotate at an angle that just makes the connecting hole 318 located at the connecting position between the transmission cylinder 315 and the connecting pipe 313. At this time, the position of the piston plate 2 39 is also restricted by the sealing plate 320 through the stretched pull rope 321, and the exhaust pipe 37 is closed, so that the sealing cylinder 317 no longer seals the connection between the transmission cylinder 315 and the connecting pipe 313, and the gas entering the transmission cylinder 315 will enter the connecting pipe 313 through the connecting hole 318.

[0062] The false touch identification mechanism 4 includes an airbag 40 connected to the air inlet 36. The airbag 40 is located on the nursing bed board 7. The piston plate 2 39 is fixedly connected to a connecting rod 41 near one end of the compression spring 310. The end of the connecting rod 41 is fixedly connected to a transmission rope 42. The transmission rope 42 is fixedly connected to a winding drum 43 at one end away from the connecting rod 41. The transmission rope 42 is wound around the surface of the winding drum 43. The axis of the winding drum 43 is fixedly connected to a shaft 44. The shaft 44 is rotatably connected to the fixed seat 34. The shaft 44 is located on the inner side of the detection seat 511. The shaft 44 is connected to the one-way conductive member 55. One end of the shaft 44 is provided with a transmission member 45 for driving the transmission wheel 1 319 to rotate, and the other end of the shaft 44 is provided with a reset member 46 for rewinding the transmission rope 42.

[0063] When the patient swings his head on the nursing bed board 7, as the patient's head moves closer to and away from one side, the airbag 40 at that position is squeezed, and the gas in the airbag 40 enters the air storage chamber 35 through the air inlet 36, so that the air pressure in the air storage chamber 35 increases, thereby pushing the piston plate 2 39 to slide on the inner wall of the air storage chamber 35, and the piston plate 2 39 squeezes the compression spring 310. The movement of the piston plate 2 39 drives the connecting rod 41 to move, and the connecting rod 41 moves downward to pull the transmission rope 42, so that the transmission rope 42 drives the winding drum 43 to rotate, and the winding drum 43 drives the shaft 44 to rotate, and the rotation of the shaft 44 drives the transmission part 45 to work. In order to prevent the patient from involuntarily swinging his head in daily life and triggering the alarm 1, the present application requires the patient to actively swing his head multiple times, and each time the patient swings his head, it will produce an impact on the airbag 40 Pressing and moving away, the airbag 40 is a mature existing technology on the market. There is a one-way valve at the connection between it and the air inlet 36, which only allows the gas in the airbag 40 to flow toward the air inlet 36. After the patient no longer presses the airbag 40, the airbag 40 will automatically absorb the external gas to swell. Therefore, each time the patient shakes his head, the piston plate 2 39 will move in the air storage chamber 35, but the distance of each movement decreases with the length of the movement of the piston plate 2 39. The piston plate 2 39 drives the connecting rod 41 to move, and the connecting rod 41 lengthens the transmission rope 42. Since the cross-sectional radius of the transmission rope 42 is small and it is wound on the surface of the winding drum 43, as the transmission rope 42 is lengthened, the change in the size of the winding drum 43 plus the wound transmission rope 42 can be ignored, and the distance the connecting rod 41 descends each time will drive the winding drum 43 to rotate at least one circle.

[0064] If the time interval between two adjacent head swings is long, the exhaust pipe 37 is in an open state, and the gas in the air storage chamber 35 will be discharged through the outlet pipe 312. After the gas in the airbag 40 no longer enters the air storage chamber 35, the compression spring 310 in a compressed state pushes the piston plate 2 39 to reset, and the piston plate 2 39 drives the connecting rod 41 to move upward, and the reset member 46 drives the winding drum 43 to reverse, so as to cooperate with the rewinding of the relaxed transmission rope 42.

[0065] If the patient moves his head several times in succession (the patient needs to move his head at least three times in succession with an interval of no more than 2 seconds to distinguish between accidental touch and active call), the gas in the airbag 40 enters the air storage chamber 35 through the air inlet 36, causing the air pressure in the air storage chamber 35 to increase, thereby pushing the second piston plate 39 to slide on the inner wall of the air storage chamber 35. The second piston plate 39 squeezes the compression spring 310. The movement of the second piston plate 39 drives the connecting rod 41 to move. The second piston plate 39 drives the sealing plate 320 to move through the pull rope 321. The sealing plate 320 stretches the elastic rope 322, so that the sealing plate 320 closes the exhaust pipe 37. As the patient continues to shake his head, the elastic rope 322 no longer stretches after being pulled to the maximum limit, and the position of the sealing plate 320 is restricted, so that the position of the piston plate 2 39 is also restricted by the sealing plate 320 through the stretched pull rope 321, so that the air pressure in the air storage chamber 35 begins to increase, and the accumulated number of rotations of the shaft 44 just makes the connecting hole 318 rotate to the connecting position of the transmission cylinder 315 and the connecting tube 313. As the patient continues to shake his head, the gas injected into the air storage chamber 35 by the airbag 40 enters the slide 22, so that the air pressure in the slide 22 increases to cooperate with the alarm button of the triggering alarm 1.

[0066] The transmission member 45 includes a second transmission wheel 48 fixedly connected to the shaft 44 , a conveyor belt 49 is installed on the outer side of the second transmission wheel 48 , and the first transmission wheel 319 is located on the inner side of the conveyor belt 49 .

[0067] When the shaft 44 rotates, the shaft 44 drives the transmission wheel 2 48 to rotate, the transmission wheel 2 48 drives the conveyor belt 49 to rotate, and the conveyor belt 49 synchronously drives the transmission wheel 1 319 to rotate. In addition, the diameter of the transmission wheel 1 319 is larger than the diameter of the transmission wheel 2 48, so that the shaft 44 drives the transmission wheel 2 48 to rotate multiple circles before the transmission wheel 1 319 can drive the connecting hole 318 to rotate to the connecting position of the transmission cylinder 315 and the connecting pipe 313.

[0068] The reset member 46 includes a vortex spring 47 . One end of the vortex spring 47 is fixedly connected to the shaft 44 , and the other end of the vortex spring 47 is fixed to the inner wall of the fixing seat 34 .

[0069] When the transmission rope 42 pulls the winding drum 43 to rotate, the winding drum 43 drives the shaft 44 to rotate, and the shaft 44 contracts the vortex spring 47. The vortex spring 47 is usually made of sheet steel or metal alloy, and is in a flat spiral shape. Its appearance is similar to a tightly wound mosquito coil. Based on the elastic deformation characteristics of the material, when torque is applied to the vortex spring 47, the spring material produces bending elastic deformation, causing it to twist in the plane. After the external force disappears, the vortex spring 47 will return to its original shape and release the stored energy, thereby realizing the energy storage and release function. When the gas in the air storage chamber 35 is discharged through the exhaust pipe 37, the compressed compression spring 310 pushes The movable piston plate 2 39 is reset, and the piston plate 2 39 drives the connecting rod 41 to move upward, so that the transmission rope 42 is in a relaxed state, and the transmission rope 42 no longer pulls the winding drum 43. At this time, the vortex spring 47 in the contracted state begins to release the stored energy, thereby driving the shaft 44 to reverse, and the shaft 44 drives the winding drum 43 to reverse to cooperate with the re-winding of the transmission rope 42, and when the shaft 44 drives the transmission wheel 2 48 to reverse, the transmission wheel 2 48 reverses the transmission wheel 1 319 through the conveyor belt 49, and the transmission wheel 1 319 drives the connecting hole 318 to reset, so that the closing cylinder 317 re-seals the connection between the transmission cylinder 315 and the connecting pipe 313.

[0070] The one-way conducting member 55 includes a transmission wheel 56 fixedly connected to the outer side of the shaft 44. A transmission cylinder 57 is provided on the outer side of the transmission wheel 56, which is rotatably connected to the outer side of the shaft 44. A rubber block 58 is fixedly connected to the outer side of the transmission cylinder 57. The rubber block 58 is located below the trapezoidal block 51. A plurality of tooth blocks 59 are fixedly connected to the side of the transmission cylinder 57 near the transmission wheel 56. A plurality of rubber clips 510 are mounted on the surface of the transmission wheel 56. The rubber clips 510 are arranged in an arc shape. The rubber clips 510 cooperate with the tooth blocks 59 to allow only one-way rotation of the transmission cylinder 57.

[0071] When the patient moves his head to one side on the bed, as the patient presses the airbag 40, the gas in the airbag 40 enters the air storage chamber 35 through the air inlet 36. The air pressure in the air storage chamber 35 increases and pushes the piston plate 2 39 to move. The piston plate 2 39 drives the connecting rod 41 to move downward, thereby driving the shaft 44 to rotate. The patient presses the airbag 40 repeatedly each time he moves his head, so that the shaft 44 rotates each time the patient moves his head. In the process of the patient's head swinging, the shaft 44 rotates multiple times. When the piston plate 2 39 descends and drives the shaft 44 to rotate, the shaft drives the transmission wheel 56 to rotate. The rubber clip 510 on the outside of the transmission wheel presses against the tooth block 59 inside the transmission cylinder 57, thereby driving the transmission cylinder 57 to rotate together. The rotation of the transmission cylinder 57 causes the rubber block 58 to rotate and squeeze the trapezoidal block 51, so that the trapezoidal block 51 slides along the inner wall of the connecting groove 50. 1 drives the piston plate three 52 to perform piston movement on the inner wall of the connecting groove 50, so as to squeeze the gas in the connecting groove 50 into the whistle 54. The faster the patient shakes his head, the farther the piston plate two 39 moves in the air storage chamber 35 within the maximum movement limit. Therefore, the more piston movements the piston plate three 52 performs in the connecting groove 50, the more continuous pumping times, and the greater the total amount of air passing through the whistle 54 per unit time, resulting in an increase in the vibration frequency of the air column in the whistle 54 and a sharper sound. Therefore, the more times the patient shakes his head spontaneously, the sharper the alarm sound of the whistle 54 is, so as to help alert the surrounding caregivers and family members. In addition, when the patient shakes his head unconsciously, that is, accidentally touches the whistle, the airflow generated by one or two piston movements is not enough to cause air vibration in the whistle 54, so that no sound is emitted, or the sound is low, thereby not affecting the patient's normal rest.

[0072] When the vortex spring 47 drives the shaft 44 to rotate in reverse, the shaft 44 drives the transmission wheel 56 to rotate in reverse, and the transmission wheel drives the rubber clip 510 to rotate in reverse. The curved surface of the rubber clip 510 and the tooth block 59 inside the transmission cylinder 57 squeeze each other, causing the rubber clip 510 to deform, thereby enabling the transmission wheel 56 to rotate relative to the inner wall of the transmission cylinder 57.

[0073] Example 2

[0074] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that there are airbags 40 and corresponding false touch identification mechanisms 4 and driving mechanisms 3 on both sides of the bed head. The airbags 40 on both sides work independently. The patient can trigger the corresponding false touch identification mechanism 4 and driving mechanism 3 by continuously shaking the head to either side, so that the patient can trigger the alarm 1 to call medical staff by continuously shaking the head to either side. In addition, the shape of the airbag 40 is an arc-shaped transition to facilitate the patient to shake the head to squeeze the gas inside the airbag 40.
