Description

Technical Field

[0001] This invention relates to a medical device, and in particular to an intelligent Heimlich maneuver chair that can improve the effectiveness of the Heimlich maneuver. Background Technology

[0002] The Heimlich maneuver, invented by Heimlich, is a first aid method for treating acute airway obstruction by thrusting into the abdomen. It is currently recognized worldwide as an effective first aid method for treating acute airway obstruction.

[0003] Figure 1 A conventional Heimlich maneuver chair is shown, comprising a back cushioning plate 101, restraint straps 102, and a percussion device 103. The back cushioning plate 101 has restraint straps 102, and the restraint straps 102 have percussion devices 103, allowing for percussion first aid by restraining the patient's body with the restraint straps 102. The restraint straps 102 include shoulder restraint straps 104, chest restraint straps 105, percussion device fixing straps 106, and waist restraint straps 107. Two shoulder restraint straps 104 are symmetrically arranged on the back cushioning plate 101. The chest restraint straps 105, percussion device fixing straps 106, and waist restraint straps 107 are arranged sequentially from top to bottom on the two shoulder restraint straps 104 to stabilize the chest, abdomen, and the position of the percussion device 103. A controller 110 of the percussion device 103 controls the percussion device 9 to perform percussion on the patient's chest.

[0004] Figure 1 While the Heimlich maneuver chair shown is convenient for performing the Heimlich maneuver on a patient, it must be operated by a professional and patients cannot perform it themselves. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent Heimlich maneuver chair that does not require operation by professionals and can improve the effectiveness of the Heimlich maneuver.

[0006] The present invention provides an intelligent Heimlich resuscitation chair for achieving the above objectives, comprising:

[0007] A chair seat with legs;

[0008] The back of the chair seat is connected to the chair back via a backrest rotation mechanism;

[0009] A protective strap fixed to the front of the chair back to secure the patient to the chair back;

[0010] A buckle located on the back of the chair;

[0011] An elastic strap with one end fixed to the chair back and the other end inserted into the buckle;

[0012] An impact device mounted on the elastic band for impacting the patient's xiphoid process; and

[0013] A controller that sequentially controls the forward tilting of the chair back, the inflation of the elastic straps, and the impact device to impact the patient's xiphoid process.

[0014] Preferably, the buckle is equipped with a strap insertion detector for detecting whether the elastic strap is inserted, and the detection signal of the elastic strap being inserted into the buckle is input to the controller so as to control the rotating mechanism to tilt forward, so as to tilt the chair back forward.

[0015] Preferably, the chair back rotation mechanism includes:

[0016] A chair back hinge mechanism that allows the chair back to rotate relative to the chair seat;

[0017] The backrest drive mechanism can be driven to tilt the chair back forward relative to the seat according to the control command of the controller.

[0018] Preferably, the intelligent Heimlich maneuver chair of the present invention further includes a backrest tilt position detection device for detecting whether the backrest has tilted forward to a predetermined position. This device sends a backrest tilt position detection signal to the controller, so that the controller can control the air pump to inflate the elastic straps based on the backrest tilt position detection signal. The predetermined position is the position of the backrest when it is tilted forward 30 degrees.

[0019] Preferably, the elastic band is provided with a band sensor on the side facing the patient's abdomen to detect whether the elastic band is close to the patient's abdomen. The sensor is used to send the detection signal of the elastic band being close to the patient's abdomen to the controller, so that the controller can control the air pump to stop the inflation operation based on the detection signal of the elastic band being close to the patient's abdomen.

[0020] Preferably, the intelligent Heimlich emergency chair of the present invention further includes a slapping device disposed on the front of the chair back for slapping the patient's back; after the controller controls the air pump to stop the inflation operation, the slapping device is activated to perform the slapping operation on the patient's back.

[0021] Preferably, after the controller controls the striking device to complete the predetermined striking operation, it activates the impact device to continuously impact the patient's xiphoid process.

[0022] Preferably, the intelligent Heimlich emergency chair of the present invention further includes a breathing detection device for detecting whether the patient's breathing is normal, and the controller controls the impact device to increase the impact force on the patient's xiphoid process based on the detection signal of abnormal breathing.

[0023] Preferably, the controller enhances the impact force on the patient's xiphoid process by controlling the power intensity and pulse width of the pulse power supplied to the impact device.

[0024] Preferably, the control stops the impact of the impact device based on the detection signal that the patient's breathing is normal, until the patient's breathing returns to normal.

[0025] The present invention has the following technical advantages over the prior art:

[0026] 1. Before performing the Heimlich maneuver, the intelligent Heimlich emergency chair of the present invention can automatically tilt forward based on the detection result of the elastic strap being inserted into the buckle on the backrest, and after tilting forward to the position, it can pat the patient's back, thereby improving the treatment effect of the intelligent Heimlich maneuver.

[0027] 2. It is easy to operate. The patient only needs to sit on the Heimlich maneuver chair, fasten the safety belt and insert the elastic strap into the buckle on the back of the chair, and the Heimlich maneuver chair can automatically complete the Heimlich maneuver. Attached Figure Description

[0041] Figure 2a and Figure 2b The basic structure of an intelligent Heimlich maneuver chair according to the present invention is shown. The intelligent Heimlich maneuver chair of the present invention includes: a seat 2 with legs 4; a backrest 3 connected to the seat 2 via a backrest rotation mechanism 24; a protective strap 8 fixed to the front of the backrest 3 for securing the patient to the backrest; a buckle 9 disposed on the backrest 3; an elastic strap 14 with one end fixed to the backrest 3 and the other end inserted into the buckle 9; an impact device 13 mounted on the elastic strap 14 for impacting the xiphoid process of the patient; and a controller that sequentially controls the forward tilting of the backrest 3, the inflation of the elastic strap 14, and the impact of the impact device 13 on the xiphoid process of the patient.

[0042] The buckle 9 of the present invention is equipped with a strap insertion detector for detecting whether the elastic strap 14 is inserted. The strap insertion detector can be a contact sensor or a proximity sensor. When the elastic strap 14 is inserted into the buckle 9, the strap insertion detector generates an insertion detection signal input to the controller, so that the controller controls the chair back rotation mechanism 24 to tilt forward, so that the chair back 3 tilts forward. This facilitates the impact device 13 on the elastic strap to generate a vertical upward and inward impact force and promote the expulsion of foreign objects from the mouth.

[0043] The chair back rotation mechanism of the present invention includes: a chair back hinge mechanism that allows the chair back 3 to rotate relative to the chair seat 2; and a chair back drive mechanism that can drive the chair back 3 to tilt forward according to the control command of the controller.

[0044] The backrest drive mechanism can be a hydraulic device including a hydraulic cylinder body and a hydraulic telescopic rod. When the controller receives a detection signal that the elastic strap 14 has been inserted into the buckle on the backrest, it sends a control command to the hydraulic control system including the hydraulic cylinder body and the hydraulic telescopic rod, causing the hydraulic pump and reversing valve of the hydraulic control system to operate, thereby causing the telescopic rod 242 to retract and drive the backrest 3 to tilt forward toward the seat 2.

[0045] In one embodiment of the invention, the controller starts a timer simultaneously with initiating the retraction movement of the telescopic rod 242. When the timer expires, the controller controls the air pump to inflate the elastic strap 14. The air pump can be positioned anywhere that does not obstruct operation, such as the bottom of the chair seat.

[0046] In another embodiment of the invention, a backrest tilt position detection device (not shown in the figure), such as a contact sensor or proximity sensor, can be provided at a predetermined position between the backrest 3 and the seat 2 to detect the forward tilt position of the backrest. When the backrest 3 tilts forward and contacts or approaches the backrest tilt position detection device, the backrest tilt position detection device sends a backrest tilt position detection signal to the controller, causing the controller to control the air pump to inflate the elastic strap 14.

[0047] The present invention can set the position of the chair back when the chair back is tilted forward by 30 degrees as a "predetermined position".

[0048] A strap sensor, such as a stress sensor, is provided on the side of the elastic strap 14 facing the patient's abdomen to detect whether the elastic strap is close to the patient's abdomen. The detection signal of the elastic strap being close to the patient's abdomen is sent to the controller, so that the controller can control the air pump to stop the inflation operation based on the detection signal of the elastic strap being close to the patient's abdomen.

[0049] like Figure 1 As shown, a slapping device 27 for slapping the patient's back is provided on the front of the chair back 3; after the controller stops the inflation operation of the air pump, it starts the slapping device 27 to slap the patient's back. After the controller controls the slapping device 27 to complete the predetermined slapping operation, it starts the impact device 13 to continuously impact the patient's xiphoid process area until breathing returns to normal.

[0050] This invention can be configured with a respiratory detection device, such as a respiratory monitor 11, to detect whether a patient's breathing is normal. Based on a detection signal indicating abnormal breathing, the controller controls the impact device to increase the impact force on the patient's xiphoid process. The controller can increase the impact force on the xiphoid process by controlling the power intensity and pulse width of the pulse power supplied to the impact device. The controller can also stop the impact device's impact based on a detection signal indicating normal breathing detected by the respiratory detection device.

[0051] See Figure 3 The impact device 13 of the present invention includes: a housing 22; an electric push rod 17 installed within the housing 22 for extending and retracting according to a striking command from a controller, the electric push rod 17 extending and retracting via known electromagnetic action; and an elastic impact device driven by the electric push rod 17. The elastic impact device can be any impact head with elasticity.

[0052] In this invention Figure 3 In the example shown, the elastic impact device includes: an impact head 21 mounted on a support plate 20; a fixed sleeve 18 connected to an electric push rod 17; and a spring 19 connected between the fixed sleeve 18 and the support plate 20.

[0053] See Figure 7a and Figure 7b The chair back hinge mechanism of the present invention includes: a chair seat connecting plate 243 with a pin hole extending from one end of the chair seat 2; a chair back connecting plate 244 with a pin hole extending from one end of the chair back 3; and a pin 245 inserted into the pin hole of the chair seat connecting plate 243 and the pin hole of the chair back connecting plate 244.

[0054] exist Figure 7a In one example shown, the backrest drive mechanism includes: a hydraulic cylinder body 241 fixed to the side of the backrest 3; and a hydraulic telescopic rod 242 extending from the hydraulic cylinder body 241 and fixed to the side of the seat 2.

[0055] exist Figure 7b In another example shown, the backrest drive mechanism includes: a hydraulic cylinder body 241 fixed to the side of the seat 2; and a hydraulic telescopic rod 242 of the hydraulic cylinder extending from the hydraulic cylinder body 241 and fixed to the side of the backrest 3.

[0056] The controller controls the hydraulic control system, which includes a hydraulic pump and a directional valve, to cause the hydraulic telescopic cylinder 242 to retract, thereby tilting the chair back 3 forward.

[0057] See Figure 8 The striking device 27 of the present invention includes: a cylinder body 271 fixed on the front of the chair back 3; a cylinder telescopic rod 272 extending from the cylinder body 271; and a striking plate 273 fixedly connected to the cylinder telescopic rod 272.

[0058] The present invention may have multiple striking devices 27, such as Figure 1 and Figure 8 The three striking devices 27 are displayed; the controller can control each striking device to perform striking operations simultaneously or sequentially.

[0059] In addition, the side of the intelligent Heimlich maneuver chair of the present invention may also be provided with an emergency button 5, an indicator light 6, and an emergency medical treatment button 7. A respiratory detector 11 is located at the center of the protective belt 8; there is a storage box 12 behind the chair back for storing an inflatable elastic strap 14 with an impact device 13; there is a voice broadcast device 25 inside the chair; and there is a power interface 26 on the side of the chair back.

[0060] When a patient experiences choking on a foreign object, the intelligent emergency chair of this invention is used as follows:

[0061] (1) The patient sits in a chair and presses the emergency button. The voice prompt function is activated, and it announces, "Please fasten your seat belt, remove the elastic strap 14 behind the chair back, insert one end of the elastic strap 14 into the buckle 9, and adjust the impact device 13 on the elastic strap 14 to..." Figure 4 The patient shown has a lower xiphoid process; in obese individuals, this extends to the chest.

[0062] (2) After the sensor inside the buckle detects the inflatable strap, a voice prompt will say "The backrest is starting to tilt forward"; the tilt angle is 30 degrees (e.g., Figure 5 As shown), forming an impact device 13 (such as...) Figure 6 (As shown) The vertical upward and inward impact force promotes the expulsion of foreign objects from the mouth.

[0063] (3) After the emergency chair is tilted forward, the voice prompt "Inflate now" is given; the elastic band is inflated until it is completely close to the patient's abdomen, and the elastic band and impact head are in complete contact with the skin, then inflation is stopped.

[0064] (4) After inflation, a voice prompt will say "Start back patting now"; the patting device will be activated, the position sensor will identify the patting plate which is at the same level as the buckle, and the patting plate will be activated to perform 5 pats. A voice prompt will say "Start impact now"; the impact device will be activated, and the impact head will move forward in a regular manner through the electric push rod driving the spring. After each set is completed, the breathing will be checked automatically and quickly. If the exhalation volume does not improve, the next set of impacts will continue, and a voice prompt will say "Start the next round of rescue now"; if the foreign object is expelled, the impact will end, and a voice prompt will say "Rescue ended".

[0065] (5) During or after the impact, you can press the emergency button again to force stop or turn off the device. If you still feel unwell after the rescue, you can quickly contact the nearest hospital through the emergency medical button for in-hospital rescue.

[0066] The intelligent Heimlich maneuver chair of this invention can be used in public places such as restaurants, airports, and hotels, and can be placed next to an AED. It can also be used in homes, especially for people living alone, to enable self-rescue.

[0067] The intelligent Heimlich emergency chair of the present invention can solve the technical problems of existing Heimlich emergency belts, emergency beds, and emergency chairs shown in the table below.

[0068]

[0069] The controller of this invention can be a processor. When the controller of this invention uses a processor, the electrical schematic diagram of the intelligent Heimlich maneuver chair is as follows: Figure 9aAs shown, the seat belt insertion detector, backrest actuator, backrest tilt position detection device, impact device, elastic seat belt, seat belt sensor, impact device, and breathing detection device are respectively connected to the controller. The controller controls the backrest actuator, elastic seat belt, impact device, and breathing detection device to perform corresponding operations in sequence according to the corresponding signals input from the seat belt insertion detector, backrest tilt position detection device, seat belt sensor, and breathing detection device.

[0070] The controller of the present invention can also be constructed from several discrete components, such as digital circuits. Figure 9b This shows a controller composed of several digital circuits. For example... Figure 9b As shown, the strap insertion detector is connected to input terminal 1 of AND gate 1, the backrest tilt position detection device is connected to input terminal 2 of AND gate 1, and the output terminal of AND gate 1 is connected to the backrest drive mechanism. This allows the elastic strap to be inserted into the buckle 9 (when both input terminals 1 and 2 of AND gate 1 are high), causing the output terminal of AND gate 1 to output a high level, thus tilting the backrest drive mechanism forward. After the backrest is tilted to its designated position, the backrest tilt position detection device outputs a low level (keeping input terminal 1 of AND gate 1 high and input terminal 2 low). When the backrest tilts forward, the output of gate circuit 1 is low, thus stopping the control of the chair back drive mechanism to tilt forward. The chair back tilt position detection device is also connected to input 1 of gate circuit 2 to detect when the elastic band is in contact with the patient's abdomen. The band sensor is connected to input 2 of gate circuit 2, and the output of gate circuit 2 is connected to the band air pump (control circuit). After the chair back is tilted to the correct position, the high level output of gate circuit 2 controls the band air pump to work. When the band sensor detects contact with the patient's abdomen, it outputs a low level, causing gate circuit 2 to tilt forward. The output terminal outputs a low level, thereby controlling the belt pump to stop working; the belt sensor is also connected to the input terminal of a timer, and the timer output terminal is connected to the driving component (such as a cylinder controller) of the striking device 27. When the belt sensor detects contact with the patient's abdomen, the timer output terminal outputs a high level, causing the striking device 27 to perform the operation of striking the patient's back. When the timer expires, it outputs a low level, thereby causing the striking device to stop performing the operation of striking the patient's back; the timer output terminal is connected to a trigger, and the output terminal of the trigger is connected to the impact device via AND gate circuit 3. The falling edge of the timer output from high level to low level causes the trigger output to change from low level to high level, causing the impact device 17 to strike the patient's xiphoid process; the respiratory detector is connected to one input terminal of AND gate circuit 3 via a decision circuit. When the respiratory detector outputs a signal that the patient's breathing is normal, the decision circuit outputs a low level (if the respiratory detector has the function of outputting a low level when breathing is normal, then the respiratory detector is directly connected to one input terminal of AND gate circuit 3), causing the impact device 17 to stop the impact operation. It should be noted that in Figure 9b In this case, the upper end of the input side of all AND gate circuits is input terminal 1, and the lower end is input terminal 2.

[0072] Step S10: Determine whether the elastic strap 14 is inserted into the buckle 9;

[0073] Step S11: When it is determined that the elastic strap 14 is inserted into or out of the buckle 9, the chair back is driven to tilt forward.

[0074] Step S12: Determine if the chair back 3 is tilted forward in place;

[0075] Step S13: When it is determined that the chair back 3 is tilted forward, the air pump starts to inflate the elastic strap 14.

[0076] Step S14: Determine whether the elastic band 14 is tightly attached to the patient's abdomen;

[0077] Step S15: When it is determined that the elastic band 14 is tightly attached to the patient's abdomen, turn off the air pump, stop inflating the elastic band 14, and start the patting device 27 to start patting the patient's back.

[0078] Step S16: Determine whether the striking device 27 has stopped striking;

[0079] Step S17: When the striking device 27 stops striking, the impact device 13 is activated to impact the lower part of the patient's xiphoid process.

[0080] Step S18: Determine if the patient's breathing is normal;

[0081] Step S19: If it is determined that the patient's breathing is abnormal, increase the intensity of the impact.

[0082] Step S20: If the patient's breathing is determined to be normal, the process ends.

[0083] This invention allows for more effective Heimlich maneuvering and does not require professional personnel to operate, making it applicable in any location.

[0084] Although the present invention has been described in detail above, it is not limited thereto, and those skilled in the art can make various modifications based on the principles of the present invention. Therefore, all modifications made in accordance with the principles of the present invention should be understood to fall within the protection scope of the present invention.
