Description

Technical Field

[0001] The invention relates to a neonatal cardiopulmonary resuscitation model, in particular to an infant cardiopulmonary resuscitation model. Background Art

[0002] The lungs of newborns are usually filled with water, which must be forced out of the lung tissue by some high-pressure ventilation. At this stage, the neonatal lung compliance is low and the chest does not rise when the air is blown. There is a transition phase after the lungs are ventilated, when the lungs become "soft" and a rise in the chest can be observed, and low-pressure ventilation should be performed regularly.

[0003] Conventional neonatal emergency models on the market currently have only two states for the airway connected to the lungs: closed and open, and can only be simulated by mechanical squeezing and lifting the head. This emergency model cannot solve the challenges faced by rigid breathing and fluid-filled lungs, nor can it show the natural change of lung compliance during the rescue process. It is also unknown whether the model's heart rate will improve during the rescue process. Sometimes, after the newborn's airway is opened, the heart rate still cannot be restored. This cannot be effectively simulated, which will lead to unsuccessful actual rescue.

[0004] Chinese patent 201822062981.9 discloses a cardiopulmonary resuscitation simulation device, including a human model and a cardiopulmonary resuscitation operating body arranged inside the human model, wherein the human model includes a base, a trunk model connected to the base, and a head model connected to the upper end of the trunk model, a support frame is arranged inside the trunk model, and the support frame has an installation cavity and a lower cavity, the spring of the cardiopulmonary resuscitation operating body is arranged in the installation cavity, the gas storage device of the cardiopulmonary resuscitation operating body is arranged in the lower cavity, and the front and rear sides of the cardiopulmonary resuscitation operating body are provided with protective covers, and the protective covers are located inside the front protective shell and the rear protective shell of the trunk model. This device cannot detect the blowing pressure and the heart rate of the model, and cannot judge invalid rescue; the process of gradual opening of the airway cannot be simulated, which does not conform to the actual rescue situation; the situation that the heart rate still does not rise after the new airway is opened cannot be simulated, which does not conform to the actual rescue situation and is easy to cause wrong rescue; the rescue result can only be judged through the device, and the rescuer has to look at the device while rescuing, which affects the rescuer's rescue. Summary of the invention

[0005] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a neonatal cardiopulmonary resuscitation model, which can detect the rescuer's blowing volume and frequency, simulate different rescue stages by controlling the degree of airway opening, make the entire rescue process more in line with the actual rescue situation, and improve the authenticity of simulation training.

[0006] To achieve the above-mentioned and other related purposes, the present invention provides a neonatal cardiopulmonary resuscitation model, comprising:

[0007] A head, wherein a main control circuit board, an air blowing port, a reversing pipe, an air inlet valve, an adjusting motor and an air pipe are arranged in the head, the reversing pipe is clamped in the air blowing port, the air inlet valve extends into the reversing pipe, the part of the air inlet valve located outside the reversing pipe is connected to the adjusting motor, the reversing pipe is connected to the air pipe, a ventilation pipe is arranged at one end of the reversing pipe connected to the air blowing port, a first sensor is arranged in the ventilation pipe, and the first sensor and the adjusting motor are respectively connected to the main control circuit board;

[0008] A trunk is connected to the torso via the trachea.

[0009] Preferably, a lung lobe and a second sensor are provided in the trunk, the trachea is connected to the lung lobe, and the second sensor is located inside the lung lobe.

[0010] Preferably, the head also includes a speaker, and the speaker is connected to the main control circuit board.

[0011] Preferably, the air inlet valve comprises a flower-shaped hole, a valve hole, a gradient hole and a rotating leaf, the flower-shaped hole is connected to the regulating motor, the gradient hole is connected to the edge of the valve hole, and the rotating leaf is located outside the edge of the plane where the flower-shaped hole is located.

[0012] Preferably, it also includes a heart rate monitoring ring, which is buckled on the outside of the torso.

[0013] Preferably, the head further comprises a mode setting key, and the mode setting key is located on the outside of the head or the torso, and the mode setting key is divided into two modes, a mild mode and a severe mode.

[0014] To sum up, the invention has the following beneficial effects: by setting the regulating motor and the air inlet valve, only continuous and effective blowing can the regulating motor drive the air inlet valve to move continuously; if the rescue process is interrupted or the rescue blowing pressure is insufficient or the rescue frequency is unqualified, the regulating motor will stop working during this rescue process, which is more in line with the actual situation of the neonatal airway during the rescue process and has a better rescue simulation effect; at the same time, the changes in the model's lung pressure and heart rate are detected to effectively prevent the rescue problem that the model's airway is open but the heart rate is still abnormal, making the rescue more thorough and avoiding the danger caused by an incomplete rescue process; by simulating the crying of a baby through a loudspeaker, the rescuer can judge the rescue results more directly, that is, stop the rescue to avoid excessive rescue that damages the health of the newborn.

It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0026] like Figures 1 to 5As shown, the present invention relates to a neonatal cardiopulmonary resuscitation model, comprising a head 1 and a trunk 2, wherein the head 1 is provided with an air blowing port 12, the lower end of the air blowing port 12 is clamped with the reversing tube 13, the reversing tube 13 is hollow, and the air inlet valve 14 is arranged inside, the air inlet valve 14 can rotate in the reversing tube 13 driven by the regulating motor 15, the air inlet valve 14 is provided with the valve hole 142 and the gradual hole 143, the gradual hole 143 has a small orifice, when the gradual hole 143 is connected with the trachea 16, only a small part of the gas can enter the trachea 16, when the regulating motor 15 drives the air inlet valve 14 to rotate, the valve hole 142 and the gradual hole 143 can be respectively connected with the air blowing port 12, so that the gas blown in by the rescuer is connected to the lung lobe 21.

[0027] like Figures 1 to 5 As shown, the ventilation pipe 17 is provided at one end of the reversing pipe 13 connected to the blowing port 12. One end of the ventilation pipe 17 is connected to the outlet reversing pipe 13. A first sensor 171 is provided in the ventilation pipe 17. The first sensor 171 can detect the pressure and frequency of the gas blown in by the rescuer at all times, and feed back the pressure and frequency data to the main control circuit board 11. The second sensor 22 is provided in the lung lobe 21 to detect the pressure of the gas entering the lung lobe 21.

[0028] like Figures 1 to 5 The mode setting key 4 is located outside the head 1 or the trunk 2 and is fixed at a certain position and connected to the main control circuit board 11 through a wire. The position of the mode setting key 4 can be fixed outside the head 1 or the trunk 2 according to actual conditions. The mode setting key 4 is divided into two modes, a mild mode and a severe mode. The rescuer presses the corresponding mode to simulate the rescue process of the newborn with the corresponding airway state.

[0029] like Figures 1 to 5 As shown in the figure, during the whole rescue process, the rescuer's blowing pressure has four states:

[0030] In the first state, when the first sensor 171 detects that the rescuer's blower pressure is insufficient (less than P0), the main control circuit board 11 will perform an analysis and assume that the blowing at this time is random noise of the model. Therefore, the adjustment motor 15 will not start, and the blown gas will not be able to enter the lung lobe 21 of the neonatal model. In other words, the rescue at this time is an invalid rescue process.

[0031] In the second state, when the pressure of the gas blown in by the rescuer reaches a certain pressure critical value P0, the first sensor 171 feeds back this information to the main control circuit board 11, and the main control circuit board 11 releases a rescue signal to simulate the breathing gas path state and heart rate state of the baby at this time, but the pressure at this time is still low, and the main control circuit board 11 will not send a signal for the adjustment motor 15 to work, and continue to keep the gradual hole 143 and the valve hole 142 disconnected from the reversing tube 13. If this pressure is maintained for rescue, the reversing tube 13 of the model is still disconnected from the lung lobe 21, and the rescue is still ineffective;

[0032] In the third state, when the gas pressure blown in by the rescuer reaches P1 (P1>P0), the first sensor 171 feeds back this information to the main control circuit board 11, and the main control circuit board 11 releases a rescue signal to simulate the breathing airway state and heart rate state of the baby at this time, and releases the working signal of the regulating motor 15. The regulating motor 15 works, and the regulating motor 15 drives the air inlet valve 14 to rotate slowly. If the rescue continues, the air inlet valve 14 will continue to rotate, so that the gradient hole 143 is first connected with the reversing tube 13. If the rescue blowing pressure and blowing frequency are reasonable, the regulating motor 15 will drive the air inlet valve 14 to continue to rotate, so that the valve hole 142 is connected with the reversing tube 13, until the air path of the newborn model is fully opened. At this time, it can be seen that the chest of the newborn model rises significantly.

[0033] In the fourth state, when the gas pressure blown in by the rescuer reaches P2 (P2>P1), this pressure is detected by the first sensor 171 and then fed back to the main control circuit board 11. The main control circuit board 11 controls the regulating motor 15 not to work and the air inlet valve 14 not to rotate. At this time, blowing is still ineffective rescue.

[0034] It should be noted that in the third state, if during the continuous rescue process, if the blowing pressure at a certain time is not between P1 and P2, the rescue process is considered to be an ineffective rescue process, and the adjusting motor 15 will not move at this time. At the same time, if the time interval between two rescue operations is short, less than the minimum interval time T1, or the time interval between the rescue pressures is long, greater than the maximum interval time T2, the rescue process is not an effective rescue process, and the adjusting motor 15 will not move at this time, and the trachea opening process will also be interrupted.

[0035] In addition, a heart rate system for different states of the newborn is integrated in the main control circuit board 11. The heart rate changes of the newborn model released by the main control circuit board 11 will be detected by the heart rate monitoring ring 3, and the detected signal will be fed back to the device end, so that the rescuer can see the heart rate changes of the newborn model more intuitively.

[0036] If the adjusted mode is the critical care mode, the lungs of the neonatal model are stiff and filled with amniotic fluid. The rescue process is divided into two rescue stages: before and after the airway is opened. In the first stage, the main control circuit board 11 releases a heart rate signal, which is detected by the heart rate monitoring ring 3 and transmitted to the device. The rescuer can observe that the chest of the neonatal model does not rise, and the heart rate remains at a relatively low and stable level or slowly decreases. The rescuer continues to blow gas into the air port 12 and keeps the blowing pressure between P1 and P2. The pressure at this time is in the third state. When the first sensor 171 detects this pressure signal and feeds back to the main control circuit board 11, the regulating motor 15 starts, driving the air inlet valve 14 to open slowly. However, at this time, the regulating motor 1 5 is a slow movement. In the first period of time of rescue, the neonatal model is blocked. Even if the air is effectively inflated, the heart rate of the neonatal model will continue to decrease or remain at a low level. The second sensor 22 cannot detect the lung pressure, indicating that the airway resistance of the neonatal model is still very large at this time, and the lungs of the neonate still have no obvious fluctuations; as the number of effective inflates increases, the valve hole 142 of the air inlet valve 14 gradually communicates with the reversing tube 13, the air path of the air inlet valve 14 and the reversing tube 13 gradually opens, the air path of the neonatal model is slowly opened, the inflating pressure detected by the first sensor 171 and the second sensor 22 is relatively close, the airway of the neonatal model is opened, and then the heart rate of the neonatal model will gradually increase. At this time, the main control circuit board 11 switches the severe mode to the mild mode;

[0037] The second stage is the mild mode stage. At this time, the lung passage of the neonatal model is open. As the number of effective rescues increases, the heart rate of the neonatal model will gradually increase and return to a normal level. At this time, the main control circuit board 11 will send a signal and the speaker 18 will emit a baby's cry, indicating that the baby has returned to normal. If the blowing pressure and frequency do not meet the requirements during the entire rescue process, even if the neonatal model's airway is opened, the neonatal heart rate will not increase and the rescue will still not be successful.

[0038] If the adjusted mode is the mild mode, the airway of the neonatal model is open, and the entire rescue process only goes through the second stage of the rescue process.

[0039] See also Figure 3In this embodiment, the regulating motor 15 drives the air inlet valve 14 to rotate slowly. After an effective rescue, the regulating motor 15 drives the air inlet valve 14 to rotate slowly by a certain angle, rather than directly driving the air inlet valve 14 to communicate with the reversing tube 13. This is also a drawback of the traditional rescue model. If there is an ineffective rescue during the entire rescue process, the regulating motor 15 will not drive the air inlet valve 14 to rotate during this rescue. Only after multiple effective rescues will the air inlet valve 14 be driven to rotate continuously, and finally the airway of the neonatal model will be fully opened.

[0040] To sum up, the invention has the following beneficial effects: by setting the regulating motor and the air inlet valve, only continuous and effective blowing can the regulating motor drive the air inlet valve to move continuously; if the rescue process is interrupted or the rescue blowing pressure is insufficient or the rescue frequency is unqualified, the regulating motor will stop working during this rescue process, which is more in line with the actual situation of the neonatal airway during the rescue process and has a better rescue simulation effect; at the same time, the changes in the model's lung pressure and heart rate are detected to effectively prevent the rescue problem that the model's airway is open but the heart rate is still abnormal, making the rescue more thorough and avoiding the danger caused by an incomplete rescue process; by simulating the crying of a baby through a loudspeaker, the rescuer can judge the rescue results more directly, that is, stop the rescue to avoid excessive rescue that damages the health of the newborn.

[0041] Therefore, the invention overcomes various defects of the prior art and has high industrial utilization value and practical value.

Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.

The main control circuit board (11) does not send a signal to adjust the motor (15) to work, and the rescue at this time is an invalid rescue process; When the first sensor (171) detects that the rescuer's blowing pressure reaches P1, the main control circuit board (11) releases a rescue signal to simulate the breathing airway state and heart rate state of the baby at this time, and releases the working signal of the regulating motor (15). The regulating motor (15) will drive the air inlet valve (14) to rotate slowly. If the rescue continues, the air inlet valve (14) will continue to rotate, so that the gradual hole (143) is first connected to the reversing tube (13). If the rescue blowing pressure and blowing frequency are reasonable, the regulating motor (15) will drive the air inlet valve (14) to continue to rotate, so that the valve hole (142) is connected to the reversing tube (13), until the airway of the newborn model is fully opened, at which time it can be seen that the chest of the newborn model rises significantly; When the first sensor (171) detects that the rescuer's blowing pressure reaches P2, the main control circuit board (11) controls the regulating motor (15) to stop working and the air inlet valve (14) to stop rotating, and the blowing at this time is still ineffective rescue; In the third state, if during the continuous rescue process, if the blowing pressure at a certain time is not between P1 and P2, the rescue process is considered to be an ineffective rescue process, and the regulating motor (15) will not move at this time.

The rescue process is divided into two rescue stages: before the airway is opened and after the airway is opened. In the first stage, before the airway is opened, the main control circuit board (11) releases a heart rate signal, which is detected by the heart rate monitoring ring (3) and transmitted to the device. The rescuer can observe that the chest of the neonatal model does not rise, and the heart rate is maintained at a relatively low stable level or a slowly decreasing state. The rescuer continues to blow gas into the blowing port (12) and maintains the blowing pressure between P1 and P2. At this time, the pressure is in the third state. When the first sensor (171) detects this pressure signal and feeds it back to the main control circuit board (11), the regulating motor (15) starts, driving the air inlet valve (14) to slowly open.

At this time, the main control circuit board (11) will send a signal and the speaker (18) will emit a baby's cry, indicating that the baby has returned to normal. If the pressure and frequency of the blowing do not meet the requirements during the entire rescue process, even if the neonatal model's airway is opened, the heart rate of the neonate will not increase and the rescue will still not be successful.
