DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0038] Refer to the instruction manual Figure 1-10 A special transport stretcher for mentally ill patients according to an embodiment of the present invention comprises a support plate 1, wherein the number of the support plates 1 is set to four, and the four support plates 1 are respectively used to fit the limbs of the mentally ill patient; a rod body 2 is fixedly installed on the side of the support plate 1, and a guard plate 3 is rotatably connected to the outer wall of the rod body 2, and a lower clamping plate 4 is fixedly installed on the side of the guard plate 3 close to the support plate 1, and the lower clamping plate 4 is used to clamp the limbs of the mentally ill patient;

[0039] It should be noted that the purpose of the above scheme is to position and fix the limbs of the mentally ill patient by rotating the lower card plate 4. The number of the guard plate 3 and the lower card plate 4 can be selected and installed according to actual needs. Figure 1 As shown, there is a sleeve at the top and bottom of the rod body 2, and the sleeve can be fixed to the side of the support plate 1 by bolts or in a detachable manner, so that the rod body 2 is fixed between the two sleeves by plugging or clamping, so that when disassembling the rod body 2, only the sleeve needs to be disassembled.

[0040] Each two transverse support plates 1 form a group of limb positioning parts, and the two transverse support plates 1 are connected by a transverse connecting plate 5. The limb positioning parts are set in two groups, and the two groups of limb positioning parts are connected by a longitudinal connecting plate 6. The support plate 1 is connected to the transverse connecting plate 5 or the longitudinal connecting plate 6 by means of clamping or bolts; Figure 2 The disclosed snap-on connection method, although it shows a large number of arranged positioning bolts 7 and positioning caps 8, is intended to allow the four support plates 1 to slightly expand or reduce the length and width to adapt to the stature of different mental patients; even in the arrangement and combination of multiple sets of snap-on connections, the combination of the support plates 1 can be adjusted by tilting and deflecting, which only needs to ensure that the holes are aligned; if there are too many sets of positioning bolts 7 and positioning caps 8 in actual applications, and the actual installation is inconvenient, then during the actual matching production, multiple transverse positioning caps 8 or multiple longitudinal positioning caps 8 can be fixed at a fixed spacing and fixed by a horizontal bar, so that when installing a vertical bar or a horizontal bar, more can be installed at one time;

[0041] In addition, the positioning bolt 7 and the positioning cap 8 are arranged on the back of the support plate 1, so that when the patient presses on the top of the support plate 1, the positioning bolt 7 and the positioning cap 8 contact the ground, which can also make the clamping more stable;

[0042] If you need to use the bolt method, you only need to replace the positioning bolt 7 and the positioning cap 8 with bolts and nuts. Although the bolt connection method is more stable, it is inconvenient to install. Therefore, you can choose the connection method according to actual needs.

[0043] A plurality of positioning bolts 7 are fixedly mounted on the back of the support plate 1. Figure 8 As shown, the positioning bolt 7 is composed of a plurality of strip structures arranged in an annular manner with equal spacing, a protrusion 10 is fixedly installed on the top of each strip structure, a conical snap ring 9 is inserted on the top of the positioning bolt 7, a positioning cap 8 is fixedly installed on the top of the conical snap ring 9, and the conical snap ring 9 and the protrusion 10 are mutually clamped; wherein, as Figure 8As shown, the multiple strip structures of the positioning bolt 7 are in the form of a cylindrical structure that expands outward, and the cross-section of the conical retaining ring 9 is set in a state where the upper opening is small and the lower opening is large, the purpose of which is to form a clamping and positioning effect. When the conical retaining ring 9 is inserted into the top of the positioning bolt 7, the protrusion 10 is squeezed by the conical retaining ring 9, shrinks inward, and finally moves to the inner cavity of the positioning cap 8, forming a clamping effect.

[0044] like Fig.10 As shown, in this solution as a disassembly and assembly solution for the conical snap ring 9, the positioning cap 8 includes a cover plate 1 81, a connecting ring 1 82, and a connecting ring 2 83. The connecting ring 2 83 is fixedly installed on the top of the conical snap ring 9. The connecting ring 2 83 is threadedly connected or clamped with the connecting ring 1 82. The top of the connecting ring 1 82 is fixedly installed with a cover plate 1 81.

[0045] It also includes an insert ring 84 and a pressing plate 85, wherein the pressing plate 85 is fixedly installed on the top of the insert ring 84. After the connecting ring 1 82 and the connecting ring 2 83 are removed from each other, the insert ring 84 is inserted into the inner cavity of the conical retaining ring 9 so that the insert ring 84 fits against the outer walls of the positioning bolt 7 and the protrusion 10, and the conical retaining ring 9 can be removed. The insert ring 84 is a disassembly and assembly tool. When the connecting ring 1 82 and the connecting ring 2 83 are disassembled and assembled with each other by means of threaded connection or clamping, the insert ring 84 is inserted into the top of the positioning bolt 7 and the protrusion 10, so that the positioning bolt 7 and the protrusion 10 shrink inwardly, and the positioning cap 8 and the conical retaining ring 9 are lifted upward to achieve the effect of removing the conical retaining ring 9.

[0046] A grip rod 11 is fixedly installed on the top of the guard plate 3, and a fixing ring 17 is fixedly installed on the top of the left and right sides of the grip rod 11. The left and right sides of the grip rod 11 are slidably connected with a slip ring 16. It can be understood that the fixing ring 17 is fixed, and the slip ring 16 can slide up and down relative to the fixing ring 17. A spring segment 18 is installed between the slip ring 16 and the fixing ring 17. Figure 6 As shown, it can be understood that the spring segment 18 is sleeved on one side of the grip rod 11, one end of the spring segment 18 is fixedly connected to the fixing ring 17, and the other end of the spring segment 18 is fixedly connected to the slip ring 16. A transverse connecting rod 14 is fixedly installed between the two slip rings 16, and a grip rod 2 15 is fixedly installed on the top of the transverse connecting rod 14. A positioning panel 12 is fixedly installed on the bottom of the transverse connecting rod 14. The interior of the guard plate 3 is arranged in a cavity-like structure, and the positioning panel 12 is plugged into the inner cavity of the guard plate 3. The outer wall of the rod body 2 is annular and has multiple groups of positioning slots 13 for adjusting the angle of the guard plate 3. The positioning panel 12 is plugged into the inner cavity of the positioning slot 13;

[0047] A semicircular ring 19 is fixedly mounted at the bottom of the guard plate 3, the inner cavity of the guard plate 3 is connected to the semicircular ring 19, and the semicircular ring 19 is sleeved on the outer wall of the rod body 2;

[0048] During actual use, hold the grip bar 11, hook the grip bar 2 15 with your fingers, and lift the horizontal connecting rod 14 and the positioning panel 12 upward. At this time, the positioning panel 12 is disengaged from the inner cavity of the positioning slot 13, and the guard plate 3 is rotated as a whole, thereby achieving the effect of adjusting the lower clamping plate 4. During actual application, the effect of quickly flipping and fixing the limb can be achieved.

[0049] like Figure 6 As shown, in a further scheme of the above scheme, the guard plate 3 includes multiple groups, wherein a lower card plate 4 is installed on one side of one part of the guard plate 3, and an upper card plate 21 is fixedly installed on one side of another part of the guard plate 3, and a pressing plate 20 is fixedly installed on the sides of the lower card plate 4 and the upper card plate 21, wherein the lower card plate 4 can fix the limb by rotating upward and downward, and the upper card plate 21 can fix the limb by fixing the limb from bottom to top. This cross-fixing method can be beneficial to the stability of the fixation. In addition, the pressing plate 20 installed on the side of the lower card plate 4 can fine-tune the lower card plate 4 by finger-stirring, and the pressing plate 20 is after the upper card plate 21 fixes the arm, the support plate 1 and the patient lie on the ground, and the upper card plate 21 is fixed more stably by pressing the pressing plate 20 downward on the ground; in addition, the materials of the lower card plate 4, the pressing plate 20 and the upper card plate 21 can be selected from materials with high elasticity such as rubber to prevent the patient's limbs from being injured.

[0050] An airbag 23 is installed in the inner cavity of the lower card plate 4 through Velcro, and a neck pad 24 is installed on the top of the support plate 1 through Velcro. The multiple airbags 23 are connected through the trachea 22. In the fixation and auxiliary monitoring scheme of the scheme, the trachea 22 can connect all the airbags 23 to each other and inflate them through the air injection equipment, so as to further fix the arm, which is conducive to the contact installation of patches or other monitoring sensors for psychiatric patients. During the inflation process, in order to have a higher user experience, a one-way valve and a manual air release valve can be installed at the air inlet end of the trachea 22. The function of the one-way valve is to prevent the airbag 23 from leaking gas after inflation, and the manual air release valve can discharge the gas according to actual needs.

[0051] In the special transport stretcher for mentally ill patients, a vital signs monitoring system is also included;

[0052] The vital signs monitoring system includes a sensor module, a power management module, a display module, a central processing module, and an alarm module;

[0053] The monitoring probe of the sensor module is installed on the surface of the airbag 23 and / or the neck pad 24. The sensor module includes a first-class sensor module and a second-class sensor module. The first-class sensor module is used for routine monitoring under normal conditions. The first-class sensor module includes a temperature sensor, a skin conductivity sensor, a heart rate sensor, and a blood oxygen sensor. If the value monitored by the first-class sensor module exceeds the preset threshold range of the system, the second-class sensor module is activated for monitoring and evaluation.

[0054] The second-class sensor module includes a pressure sensor and an inertial measurement unit; the inertial measurement unit integrates an accelerometer and a gyroscope; the second-class sensor module is used for abnormal patient monitoring; if the value monitored by the second-class sensor module exceeds the preset threshold range of the system, the vital sign data is determined to be abnormal, and an alarm signal is issued through the alarm module;

[0055] The sensor module is used to transmit the collected vital sign data to the central processing module, and the central processing module performs data analysis and judgment;

[0056] The central processing module is used to screen the vital sign data according to the threshold set by the system. If an abnormality is detected, the second type of sensor module is activated for further monitoring and a signal is sent to the warning module at the same time;

[0057] The power management module is used to provide power to the sensor module, the central processing module, the display module and the warning module;

[0058] The display module is used to keep data synchronization with the central processing module, update the vital signs data in real time, and display the vital signs data in numerical form;

[0059] The warning module is used to receive instructions from the central processing module. When abnormal vital sign data is detected, it triggers an alarm signal and notifies medical staff to perform manual intervention.

[0060] For the special transport stretcher for mentally ill patients, it should be noted that in actual use, according to the approximate body size of the patient, the horizontal connecting plate 5 and the longitudinal connecting plate 6 are installed on the back of the four supporting plates 1, and then the patient's limbs are turned over and fixed by the lower clamping plate 4 or the upper clamping plate 21; in addition, the patient's limbs can be fixed respectively by a single supporting plate 1, and then the four supporting plates 1 are assembled; these two installation methods can be adjusted according to actual needs to improve the convenience of limb positioning of mentally ill patients, and finally the mentally ill patients can be transported by assembling the entire stretcher;

[0061] What needs to be explained about the vital signs monitoring system is that the essence of the vital signs monitoring system is to monitor the relevant data of the mentally ill patients through sensors. In the actual application process, it is not unnecessary to add a large number of useless functions to enhance the selling point. Since the limb coordination ability of the mentally ill patients themselves is not perfect, it is more difficult for them to actively intervene and fit the patches of the relevant monitoring sensor probes than for normal people. Therefore, the limb fixing structure of the stretcher itself is combined to simultaneously monitor some vital signs information of the patient, so as to achieve the effect of killing two birds with one stone. The system does not require too high monitoring accuracy, and it can be understood that it is only used for auxiliary monitoring and warning. In actual applications, if the sensor monitoring point is worried about instability, the guard plate 3, the lower card plate 4, and the upper card plate 21 can be wrapped around the whole by medical straps to achieve secondary fixation. In this way, the stability of limb fixation can be further improved with the squeezing of the airbag.

[0062] In addition, the sensor module can also input two simple evaluation models into the judgment of the central processing module through the routine monitoring of the first type of sensor module and the abnormal monitoring of the second type of sensor module, which is conducive to the analysis of data integration and the use effect of the solution in practical applications;

[0063] The two evaluation models can be expressed as a regular monitoring model and an abnormal monitoring model respectively;

[0064] In the conventional monitoring model, S norm represents the routine vital signs monitoring index, S norm Used to assess the patient's basic vital signs. norm The higher the value, the greater the possibility of adverse conditions in the normal state; the skin temperature T of the mentally ill patient measured by the temperature sensor s , the skin conductance G is measured by the skin conductance sensor s , G s It can be used to analyze the patient's sympathetic nerve activity level and reflect the mood and stress changes of mental patients; the heart rate sensor measures the current heart rate H s , H s The sharp fluctuations of mean that the psychiatric patient is anxious, nervous or in an abnormal physiological state. H0 represents the baseline heart rate. The current blood oxygen saturation O is measured by the blood oxygen sensor. s , O s If it decreases, it means hypoxia or respiratory system abnormality. O0 represents the baseline blood oxygen saturation;

[0065]

[0066] Where α is the temperature and conductivity index conversion factor, which is used to adjust the amplitude of the index change to ensure the calculation stability; β T and β Gare the weighting coefficients of skin temperature and skin conductance, β T and β G It can be optimized through experience or machine learning methods, T and β G Used to balance the contribution of different sensors to the overall monitoring index; γ H is the heart rate oscillation factor, γ H Used to control the impact of heart rate fluctuations on the overall index; S is the blood oxygen smoothing factor, γ S Used to adjust the range of changes in the blood oxygen index to avoid false alarms caused by small fluctuations;

[0067] In the above formula, the first term Exponential-logarithmic transformation is used to enhance the impact of high temperature or high skin conductance data, making abnormal conditions more prominent, while the logarithmic function is used to ensure that the values ​​are within a reasonable range and do not increase infinitely;

[0068] The second term γ H ·|sin(H s -H0)|Use the sine function to calculate the fluctuation amplitude of the heart rate, ensuring that the contribution value is low under normal circumstances, but when the heart rate deviates too much from the baseline value, this item increases rapidly;

[0069] Item 3 The Sigmoid-S function is used to process blood oxygen data to ensure that the impact is more obvious when blood oxygen is close to the critical value, making it easier for the subsequent monitoring mechanism to be triggered when blood oxygen decreases;

[0070] In the anomaly monitoring model, S abn represents the abnormal behavior monitoring index, S abn Used to determine whether the patient has abnormal conditions such as strenuous exercise, struggle or fall, S abn The higher the value, the greater the possibility of abnormal behavior; A is measured by the accelerometer x , A y , A z , A x , A y , A z Respectively represent the acceleration values ​​of the accelerometer in three directions, which are used to monitor the patient's movement amplitude and direction changes; the current pressure data P is measured by the pressure sensor s , P s Used to analyze the patient's limb stress. If the pressure suddenly changes, it may mean a struggle or abnormal tension. The G x , G y and G z , G x , G y and G zRespectively represent the angular velocity of the gyroscope in three directions, which is used to determine whether the patient has violent rotation or falls;

[0071]

[0072] where δ A is the acceleration anomaly impact factor, δ A Used to adjust the contribution of acceleration to the abnormal index; δ P is the pressure abnormality influencing factor, δ P Used to control the impact of abnormal pressure on the overall index; δ G is the influence factor of angular velocity anomaly, δ G Used to adjust the contribution of angular velocity changes to the anomaly index;

[0073] What needs to be explained about the above formula is that the first term Used to calculate the absolute sum of the three-axis acceleration and use The power amplifies the impact of larger motion signals to highlight the impact of intense motion and ensure that minor motion does not cause false alarms;

[0074] Item 2 The pressure data is squared to enhance the impact of intense struggle or compression situations, ensuring that small pressure changes are not mistaken for abnormalities;

[0075] Item 3 A negative exponential function is used to calculate the attenuation of the gyroscope data to ensure that when the angular velocity is too large, the term approaches 0, thereby weakening the impact of high-speed rotation on the overall index to reduce false alarms;

[0076] The final monitoring decision is expressed as:

[0077]

[0078] Among them, θ1 and θ2 are the trigger thresholds of the conventional monitoring model and the abnormal monitoring model, respectively, which can be optimized through clinical experiments or machine learning methods to make the alarm triggering more reasonable.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
