Description
Technical Field
[0001] The present invention relates to the technical field of electrophysiological signals, and in particular to an integrated electrophysiological signal information monitoring and acquisition device. Background Art
[0002] Acquiring electrophysiological signals of patients is of great significance for monitoring and judging the health status of patients. The electrophysiological signals commonly used in hospitals usually include cardiac electrophysiological signals (electrocardiogram ECG), brain electrophysiological signals (electroencephalogram EEG), nerve electrophysiological signals (electromyogram EMG) or electrophysiological signals of the abdomen of pregnant women (fetal electrocardiogram or FECG), etc. When collecting electrophysiological signals, electrodes are usually attached to the parts of the patient that need to be monitored. Then the electrodes continue to collect the electrophysiological signals of the patient's part for several hours. When collecting electrophysiological signals from the patient's head, the position of the electrodes is usually fixed by an elastic headgear. The position of each electrode requires medical staff to make detailed adjustments according to the specific conditions of different patients. To ensure the sensitivity of the electrode in acquiring data, because the shapes and sizes of the heads of different patients are different, in order to ensure that the elastic headgear can be worn tightly on the patient's head, the elastic headgear needs to be able to remain tight on heads of different sizes. This results in the elastic headgear usually having a greater tightening force on patients with larger heads, which will cause the patients to feel uncomfortable. On the other hand, the elastic headgear is made of flexible material. If the patient's head turns or swings during the monitoring process, it is easy to cause friction between the headgear and the pillow or seat and cause deformation. At this time, a part of the headgear moves relative to the patient's head under the deformation, causing part of the electrode to be dragged and slightly offset, affecting the monitoring sensitivity of the electrode at that location. Therefore, in response to the above problems, it is urgent to develop an integrated electrophysiological signal information monitoring and acquisition device. Summary of the invention

[0055] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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.
[0056] When collecting electrophysiological signals from the patient's head, existing devices usually fix the position of the electrode through an elastic head cap, and the position of each electrode needs to be carefully adjusted by medical staff. However, because the shapes and sizes of the heads of different patients are different, in order to ensure that the elastic head cap can be tightly worn on the patient's head, the elastic head cap usually has a large elastic deformation and its own elasticity, which causes the elastic head cap to have a greater tightening force on patients with larger heads, resulting in lower patient comfort during monitoring. On the other hand, the elastic head cap is made of flexible material. If the patient's head turns or swings during monitoring, it is easy to cause friction between the elastic head cap and the pillow or seat, causing deformation. Some electrodes are slightly offset by the force of the deformation of the elastic head cap, resulting in reduced sensitivity of the electrode monitoring at that location.
[0057] Therefore, the present invention proposes an integrated electrophysiological signal information monitoring and acquisition device. Figure 1-Figure 5For example, it includes: a wearing cap 1, which is composed of staggered longitudinal fixing strips 101 and transverse fixing strips 102, the wearing cap 1 is made of rigid non-deformable material, and the wearing cap 1 is provided with an assembly part 103; a plurality of fixing rings 2, all of which are fixedly connected to the wearing cap 1, and an adjustment column 3 is ball-connected in the fixing ring 2, and a first cavity 301 and a second cavity 302 are provided in the adjustment column 3; a sliding rod 4, which penetrates and is slidably connected to the first cavity 301 of the adjacent adjustment column 3, and the sliding rod 4 is provided with a sliding disk 5; an electrode sheet 6, which is installed on the side of the sliding disk 5 away from the sliding rod 4, and is used to collect electrophysiological signals of adjacent parts; a telescopic mechanism, the number of which is the same as the number of fixing rings 2, which is arranged in the first cavity 301 of the adjacent adjustment column 3, and the telescopic mechanism uses the air pressure in the first cavity 301 to control the sliding rod 4 to extend or retract relative to the adjacent adjustment column 3; an adjusting mechanism, the number of which is the same as the number of fixing rings 2, which is arranged on the adjacent adjustment column 3, and is used to adjust the deflection angle of the adjacent adjustment column 3 relative to the adjacent fixing ring 2.
[0058] In the above scheme, the wearing cap 1 is made of a rigid non-deformable material, and the longitudinal fixing strips 101 and the transverse fixing strips 102 together form a staggered grid structure to ensure that the patient's head is comfortable and breathable, while avoiding tensile deformation when the wearing cap 1 is squeezed. The fixing ring 2 is ball-connected with the adjustment column 3, which is convenient for medical personnel to adjust the position of the electrode sheet 6 and the patient's head through the adjustment column 3 to ensure the accuracy of electrophysiological signal collection. The shape of the sliding disk 5 can be circular, spherical, square or other shapes. A rubber ring is attached to the lower side of the sliding disk 5 to facilitate the sliding disk 5 to adapt to the shape of different patients' heads and increase the comfort of the patient when the sliding disk 5 contacts the patient's head. The assembly part 103 includes two, and a data chip (also called a control terminal) that controls all electrode sheets 6 and collects corresponding data is installed in the assembly part 103. The electrode sheet 6 and the control The terminal is electrically connected, and the assembly portion 103 is provided with an existing auxiliary fixing device (such as a chin strap on a helmet, an ear fixing strap, etc.), which is used to assist the patient in wearing the device (not shown in the figure), and then fix the device on the patient's head. The specific number of fixing rings 2 will vary according to different styles. Medical staff can freely activate some electrode sheets 6 for collection by controlling the control terminal, and it is not necessary to activate all electrode sheets 6 at the same time to work. The wearing cap 1 is made of lightweight plastic material, and the electrode sheet 6 adopts flexible circuit printing technology to greatly reduce the weight of the electrode sheet 6 and reduce the burden on the patient when wearing it. The flexible electrode sheet 6 can better adapt to the actual situation of the patient's head, improve the contact rate between the electrode sheet 6 and the patient's head, thereby simultaneously improving the accuracy of the electrode sheet 6 signal acquisition and the comfort of the patient when wearing it.
[0059] The specific working principle is: the medical staff first applies conductive grease to promote conductivity on the electrode piece 6 that needs to work (while promoting the transmission of electrical signals, it also helps to bond the electrode piece 6 to the patient's head), and wears the device on the patient's head. Then the medical staff first controls all the sliding rods 4 to extend toward the patient's head through the telescopic mechanism, so that all the electrode pieces 6 are in a fit with the patient's head. Then the medical staff adjusts the specific position of the adjustment column 3 that needs to work through the adjustment mechanism in turn, to ensure that the electrode piece 6 on it accurately collects the electrophysiological signal of the patient's head at the adjusted position. Then the medical staff controls the control terminal to activate the electrode piece 6 that needs to work, and the electrode piece 6 works to collect the electrophysiological signal at the corresponding position of the patient's head. After continuous monitoring for several hours, the medical staff removes the device from the patient's head, controls the corresponding components to reset, and analyzes and organizes the collected data. The medical staff diagnoses the patient's condition by reading the collected electrophysiological signal information.
[0060] In the above operation, after the patient fixes the wearing cap 1 on the head through the auxiliary fixing device (at this time, all the sliding rods 4 and the sliding disk 5 are extended to fit the patient's head, thereby consolidating the relative fixed state between the wearing cap 1 and the patient's head), the wearing cap 1 and the patient's head are in a relatively fixed state. At this time, because the wearing cap 1 is made of a rigid and non-deformable material, when the patient's head turns during the monitoring process, causing the wearing cap 1 to contact the chair or pillow, the wearing cap 1 will not be deformed after being squeezed, nor will it cause the electrode sheet 6 to be subjected to lateral pulling force. Therefore, there will be no relative sliding between the electrode sheet 6 and the patient's head, thereby ensuring the precision of the monitoring data of the electrode sheet 6. At the same time, the connection relationship between the fixing ring 2 and the sliding rod 4 and the adjustment column 3 is utilized to enable medical staff to flexibly adjust the position of the electrode sheet 6, thereby ensuring that the electrode sheet 6 accurately collects signals from the corresponding parts of the patient's head.
[0061] Preferably, Fig.11 For example, the electrode sheet 6 at least includes: EEG electrodes: FP1, FP2, GND, REF, Fz, Cz, Pz, C3, C4, T3, T4, O1, O2, SL, SR; electrooculogram electrodes: EOG1, EOG2; and electrocardiogram electrodes: ECG.
[0062] In the above scheme, by integrating multiple physiological signal acquisition functions such as EEG, EOG and ECG into one device (wherein the types of electrode sheets 6 are not limited to the types mentioned above, and the EOG electrooculogram electrodes and ECG electrocardiogram electrodes are connected to the patient's eyelids and heart by wires, which are not specifically shown in the figure), multifunctional integration is achieved, and multiple physiological signals are acquired at the same time, so that the time of signal acquisition is more synchronized, thereby improving the accuracy of the acquisition of electrophysiological signal information of patients.
[0063] Preferably, Figure 5-Figure 7For example, the telescopic mechanism includes: a rotating disk 8, which is rotatably connected to the first cavity 301 of the adjusting column 3, and two through holes are opened on the rotating disk 8, in which a first one-way valve 9 is fixedly connected to one of the through holes, and a second one-way valve 10 is fixedly connected to the other through hole, and the air flow directions of the first one-way valve 9 and the second one-way valve 10 are opposite; a baffle plate 11, which is fixedly connected to the first cavity 301 of the adjusting column 3, and the baffle plate 11 is sealed with the two through holes on the rotating disk 8; a rotating component, which is arranged in the first cavity 301 of the adjusting column 3, and is used to control the rotation of the adjusting column 3 according to the position of the sliding rod 4, and then switch the position of the through hole on the rotating disk 8.
[0064] The above scheme aims to specifically disclose a telescopic mechanism, wherein the rotating disk 8 is sealedly connected to the first cavity 301, and the first cavity 301 is divided into two cavities of different volumes, wherein a sliding rod 4 is installed in one cavity, and the other cavity is connected to an existing air supply device through a hose, and the existing air supply device can be an electric-controlled air supply device or a manual-controlled air supply device, which can realize the functions of air supply and air suction at the same time, and the air supply device is connected to all the first cavities 301 at the same time, and the conduction directions of the first one-way valve 9 and the second one-way valve 10 are opposite, so that Figure 6 For example, if the first one-way valve 9 can conduct the gas flowing from top to bottom and block the gas flowing from bottom to top, the second one-way valve 10 can conduct the gas flowing from bottom to top and block the gas flowing from top to bottom.
[0065] The working principle of the telescopic mechanism is: Figure 6For example, in the initial state, the sliding rod 4 is located on the side close to the rotating disk 8, the first one-way valve 9 can conduct the gas flowing from top to bottom, and the baffle plate 11 and the through hole of the second one-way valve 10 are sealed and matched. At this time, when the medical staff supplies gas to the first cavity 301 by operating the gas supply device, the gas flows into the space where the sliding rod 4 is located from the first one-way valve 9 in one direction, and squeezes the sliding rod 4 downward. Under the action of the gas pressure, the sliding rod 4 drives the sliding disk 5 and the electrode sheet 6 to extend downward, so that the sliding disk 5 and the electrode sheet 6 are in contact with the patient's head. At this time, because all the sliding rods 4 are subjected to the same gas pressure, no matter how long the adjacent sliding rods 4 extend out of the adjustment column 3, the squeezing force of all the sliding disks 5 on different parts of the patient is the same, which ensures the patient's comfortable experience while prompting all the sliding disks 5 to contact the patient's head together. When the patient no longer needs to wear the device, the medical staff removes the device from the patient's head and continues to supply air to the first cavity 301 through the air supply device, while operating all rotating components, switching the relative positions of the first one-way valve 9 and the adjacent second one-way valve 10, so that the baffle plate 11 blocks the first one-way valve 9, and the second one-way valve 10 is no longer blocked by the baffle plate 11. At this time, the medical staff extracts all the gas in the first cavity 301 through the air supply device, so that the gas flows upward from all the second one-way valves 10, thereby prompting all the sliding rods 4 to retract into the adjacent adjustment columns 3. When the sliding rods 4 are fully reset, the adjacent rotating components are automatically triggered to work, and the relative positions of the first one-way valve 9 and the adjacent second one-way valve 10 are exchanged again. The medical staff closes the existing air supply device and prepares to measure the head of the next patient.
[0066] Preferably, Figure 6 and Figure 7 For example, the rotating assembly includes: a fixed gear 12, fixedly connected to the rotating disk 8; an extrusion block 13, slidably connected to the first cavity 301 of the adjusting column 3, and located between the rotating disk 8 and the sliding rod 4, a rack meshing with the fixed gear 12 is slidably connected to the extrusion block 13, and a reset spring is installed between the rack and the extrusion block 13, there is damping at the connection between the rotating disk 8 and the adjusting column 3, the extrusion block 13 is extruded and matched with the sliding rod 4, and a first elastic member 131 is installed between the extrusion block 13 and the adjusting column 3; a spring telescopic rod 14, fixedly connected to the adjusting column 3, the telescopic end of the spring telescopic rod 14 is fixedly connected to the limiting rod 15, and the limiting rod 15 is limited and matched with the extrusion block 13; an extrusion semi-ring 16, fixedly connected to the sliding rod 4, and the extrusion semi-ring 16 is extruded and matched with the limiting rod 15.
[0067] In the above scheme, an inclined surface is provided on the lower side of the extrusion block 13, and the sliding rod 4 drives the extrusion block 13 to move horizontally by squeezing the inclined surface on the lower side of the extrusion block 13. The adjustment column 3 is slidably connected to the extrusion block 13 through the support rod. The first elastic member 131 can be a spring or other elastic member used to push the extrusion block 13 to move and reset. The side of the limiting rod 15 close to the extrusion block 13 is provided with an inclined surface, thereby prompting the limiting rod 15 to limit the extrusion block 13 (to Figure 8 For example, the extrusion semi-ring 16 can be a semicircular ring, or any other shape that is convenient for extrusion and matching with the adjacent limiting rod 15. The extrusion semi-ring 16 moves by extruding the limiting rod 15, thereby releasing the limiting of the limiting rod 15 and the extrusion block 13. The damping between the rotating disk 8 and the adjusting column 3 is used to slow down the rotation speed of the rotating disk 8, ensuring that the rotating disk 8 slowly rotates and resets only after the extrusion block 13 is completely reset.
[0068] The working principle of the rotating assembly is as follows: the initial state is as follows Figure 8 As shown, the limiting rod 15 limits the extrusion block 13, the first elastic member 131 is in a compressed state, the sliding rod 4 moves downward under the gas pressure, and the inclined surface on the lower side of the extrusion block 13 loses contact with the sliding rod 4. When the medical staff removes the device from the patient's head, the sliding rod 4 continues to move downward by injecting gas into the first cavity 301 until the extrusion semi-ring 16 squeezes the limiting rod 15 (as shown in FIG. Fig. 9 As shown in the figure, the limit rod 15 squeezes the telescopic end of the spring telescopic rod 14, the spring telescopic rod 14 is compressed and stored, and the limit rod 15 releases the limit on the extrusion block 13. The extrusion block 13 moves under the elastic force of the first elastic member 131, and drives the fixed gear 12 and the rotating disk 8 to rotate through the rack, switching the relative positions of the adjacent first one-way valve 9 and the adjacent second one-way valve 10. Subsequently, when the medical staff controls the sliding rod 4 to move upward and reset by extracting gas, the sliding rod 4 contacts and squeezes the inclined surface on the lower side of the extrusion block 13 during the movement, and the extrusion block 13 is affected. During the resetting process of the extrusion block 13, the rack is pulled to move by the reset spring, and the rack drives the rotating disk 8 to rotate slowly through the fixed gear 12, and slowly exchanges the positions of the adjacent first one-way valve 9 and the adjacent second one-way valve 10. When the extrusion block 13 squeezes and passes through the limit rod 15, the limit rod 15 restores the limit of the extrusion block 13, and the extrusion block 13 gradually pulls the rack to move together through the reset spring, and the rack drives the rotating disk 8 to rotate, and the rotating disk 8 gradually drives the adjacent first one-way valve 9 and the adjacent second one-way valve 10 to rotate and reset.
[0069] Preferably, Figure 3-Figure 6For example, the adjustment mechanism includes: a pressure plate 17, which is rotatably connected to the adjustment column 3; a piston rod 18, which is slidably connected to the second cavity 302 of the adjustment column 3, the piston rod 18 and the pressure plate 17 are rotatably and slidably connected, a second elastic member 181 is installed between the piston rod 18 and the adjustment column 3, the pressure plate 17 is provided with a pressing portion, and the connection between the piston rod 18 and the adjacent pressure plate 17 is located between the pressing portion of the pressure plate 17 and the rotation connection between the pressure plate 17 and the adjustment column 3; a first pneumatic telescopic rod 19, which is fixed to one side of the wearing cap 1 close to the adjacent fixing ring 2, The fixed ring 2 is slidably connected to the limit frame 20, the limit frame 20 is fixedly connected to the telescopic end of the first pneumatic telescopic rod 19, and the first pneumatic telescopic rod 19 is connected to the second cavity 302; the sliding blocks 21, the number of which is at least twice the number of the fixed rings 2, are respectively slidably connected to the side of the adjacent longitudinal fixing bar 101 close to the adjacent limit frame 20 and the side of the adjacent transverse fixing bar 102 close to the adjacent limit frame 20, the sliding block 21 is squeezed and matched with the adjacent limit frame 20, the sliding block 21 is ball-connected with a connecting rod 22, and the connecting rod 22 is ball-connected with the adjacent adjustment column 3.
[0070] The above scheme aims to disclose a specific adjustment mechanism, in which the number of sliding blocks 21 is four times the number of fixed rings 2, that is, four sliding blocks 21 are installed near one fixed ring 2, and the four sliding blocks 21 are symmetrically installed at adjacent longitudinal fixed strips 101 and adjacent transverse fixed strips 102 respectively. The opposite sides of the sliding blocks 21 and the adjacent limiting frames 20 are provided with transverse stripes for increasing the friction between the two, thereby enhancing the limiting effect of the limiting frame 20 on the adjacent sliding blocks 21. The second elastic member 181 is a spring, and the second cavity 302 is divided into two cavities by the piston rod 18, one of which is connected to the outside, and the other cavity stores gas and is connected to the first pneumatic telescopic rod 19 through a connecting pipe. The gas in the cavity flows into the first pneumatic telescopic rod 19. When the pressure plate 17 is adjusted, the pressure drop 22 is gradually reduced, and the pressure drop 22 is gradually reduced, and the pressure drop 22 is gradually reduced. When the pressure plate 17 is adjusted, the pressure drop 22 is gradually reduced, and the pressure drop 22 is gradually reduced. When the pressure plate 17 is adjusted, the pressure drop 22 is gradually reduced, and the pressure drop 22 is gradually reduced. When the pressure plate 17 is adjusted, the pressure drop 22 is gradually reduced, and the pressure drop 22 is gradually reduced. When the pressure plate 17 is adjusted, the pressure drop 22 is gradually reduced, and the pressure drop 22 is gradually reduced. When the pressure plate 17 is adjusted, the pressure drop 22 is gradually reduced, and the pressure drop 22 is gradually reduced.
[0071] The working principle of the adjustment mechanism is as follows: taking the uppermost adjustment column 3 as an example, the medical staff first presses the pressure plate 17 on the adjustment column 3 that needs to be adjusted, and presses the pressure plate 17 toward the adjustment column 3. The pressure plate 17 rotates to drive the piston rod 18 to move, and the second elastic member 181 is compressed and stored. The piston rod 18 squeezes the adjacent gas into the first pneumatic telescopic rod 19, and the first pneumatic telescopic rod 19 drives the limit frame 20 to move to the side away from the sliding block 21, releasing the limit on the sliding block 21, and then the sliding block 21 can slide freely relative to the wearing cap 1, and the medical staff The position of the swing adjustment column 3 is adjusted, and the electrode sheet 6 is adjusted to the position to be monitored. At this time, the four sliding blocks 21 and the connecting rod 22 swing freely according to the different swing positions of the adjustment column 3. Then the medical staff releases the pressure plate 17, and the piston rod 18 moves and resets under the drive of the second elastic member 181, thereby causing the first pneumatic telescopic rod 19 to drive the limit frame 20 to move and reset, and the limit frame 20 restores the limit on the four sliding blocks 21. The four sliding blocks 21 cannot move. At this time, the adjustment column 3 is limited by the four connecting rods 22 and is also in a relatively fixed state.
[0072] In the above-mentioned embodiment, the sliding rod 4 and the adjacent sliding plate 5 can be regarded as being fixedly connected, while in the following embodiment, the sliding rod 4 and the adjacent sliding plate 5 are slidably connected.
[0073] Preferably, Figure 5 and Figure 6 For example, the adjustment mechanism also includes: a second pneumatic telescopic rod 23, fixed to the sliding rod 4, the telescopic end of the second pneumatic telescopic rod 23 is fixed to the sliding disk 5, the sliding rod 4 is slidably connected to the adjacent sliding disk 5, the second pneumatic telescopic rod 23 is connected to the second cavity 302, and the second pneumatic telescopic rod 23 is used to drag the sliding disk 5 into the first cavity 301.
[0074] In the above scheme, the second pneumatic telescopic rod 23 is connected to the gas storage cavity of the second cavity 302 through the second connecting pipe. When the second cavity 302 squeezes the gas into the second pneumatic telescopic rod 23, the telescopic end of the second pneumatic telescopic rod 23 drives the sliding plate 5 to move upward and reset. By adding a second pneumatic telescopic rod 23 to the sliding rod 4, when the medical staff operates the pressing plate 17, the sliding plate 5 is dragged upward at the same time to reduce the friction between the sliding plate 5 and the patient's head, so that the medical staff can adjust the position of the sliding plate 5 conveniently.
[0075] Preferably, Figure 5 and Figure 6 For example, the volume of the gas stored in the second cavity 302 is greater than the sum of the volume of the first pneumatic telescopic rod 19 and the volume of the second pneumatic telescopic rod 23 .
[0076] In the above scheme, by controlling the volume of the first pneumatic telescopic rod 19 and the second pneumatic telescopic rod 23, it is ensured that the gas in the second cavity 302 is in a compressed state when entering the first pneumatic telescopic rod 19 and the second pneumatic telescopic rod 23, thereby ensuring that no matter how much force the medical staff applies to the pressure plate 17, the telescopic ends of the first pneumatic telescopic rod 19 and the second pneumatic telescopic rod 23 can move a sufficient distance, thereby reducing the difficulty of operating the device.
[0077] Preferably, Figure 2 and Figure 5-Figure 7 For example, it also includes: an auxiliary fixing component, which is arranged on the outside of the wearing cap 1, and is used to enhance the anti-extrusion ability of the adjustment column 3. The auxiliary fixing component includes: an arc plate 24, which is rotatably connected to the assembly part 103 of the wearing cap 1; a fastening block 25, the number of which is the same as the number of the adjustment column 3, and is slidably connected to the adjacent adjustment column 3. The fastening block 25 is extruded and matched with the arc plate 24, and the fastening block 25 is provided with an extrusion part 251, which is extruded and matched with the piston rod 18, and a third elastic member 252 is installed between the fastening block 25 and the adjustment column 3.
[0078] In the above scheme, the arc plate 24 is a rigid material, and the arc plate 24 can only cover 1 / 2 of the outer side of the wearing cap 1 at most at the same time. The arc plate 24 is used to support the back of the patient's head, thereby providing the patient with a more comfortable lying experience. When the fastening block 25 is not squeezed by the arc plate 24, it is acted upon by the third elastic member 252, and the squeezing part 251 is separated from the piston rod 18, and the two will not affect each other.
[0079] The working principle of the auxiliary fixing component is as follows: when the medical staff adjusts the position of the adjustment column 3 on the back side of the patient's head, the arc plate 24 is rotated to the front side of the patient. When the medical staff completes the adjustment of the adjustment column 3 on the back side of the patient's head, the arc plate 24 is rotated to the back side of the patient's head. At this time, the arc plate 24 wraps the adjustment column 3 on the back side of the patient's head to prevent the pressure plate 17 from being accidentally squeezed during the patient's shaking of the head, causing the electrode sheet 6 to deviate from the adjusted position. When the arc plate 24 squeezes the adjacent fastening block 25 during the rotation process, the fastening block 25 moves downward, and the third elastic member 252 is compressed and stored. At the same time, the fastening block 25 squeezes the piston rod 18 outward through the squeezing part 251. The movement of the piston rod 18 forms a negative pressure, which in turn causes the first pneumatic telescopic rod 19 to be subjected to an outward extending force, thereby making the limit frame 20 and the sliding block 21 fit more closely, so as to enhance the force of the limit frame 20 to limit the sliding block 21, and make the device more stable.
[0080] Preferably, Figure 1 , Figure 2 and Fig.10For example, it also includes: a convenient airbag 26, which is installed on the outside of the assembly part 103, and the convenient airbag 26 is installed with a symmetrically distributed first quick-release connector and a symmetrically distributed third one-way valve. The assembly part 103 is provided with an air inlet cavity 104 and an air outlet cavity 105, and all first cavities 301 are connected with the air inlet cavity 104 and the air outlet cavity 105 through a hose, and a fourth one-way valve is provided at the connection between the hose and the air inlet cavity 104 and the air outlet cavity 105. The air inlet cavity 104 and the air outlet cavity 105 are both provided with a second quick-release connector that is connected to the outside world, and the second quick-release connector is connected and cooperated with the first quick-release connector on the convenient airbag 26.
[0081] In the above scheme, a mechanism for simultaneously supplying and exhausting air to all first cavities 301 is specifically disclosed, wherein the convenient airbag 26 is an existing airbag, and a third one-way valve and a first quick-release connector are provided at both ends thereof, wherein the first quick-release connector and the third one-way valve at one end are used to inhale air into the convenient airbag 26, and the first quick-release connector and the third one-way valve at the other end are used to eject the gas in the convenient airbag 26 outward, and the fourth one-way valve on the air inlet cavity 104 can only transport the gas into the hose, while the fourth one-way valve on the air outlet cavity 105 can only transport the gas into the hose. The valve can only transport gas from the hose to the air outlet cavity 105. The first quick-release connector and the second quick-release connector are both existing devices. When the medical staff inflates the air inlet cavity 104, the first quick-release connector at the jet-jet end of the convenient air bag 26 is connected to the second quick-release connector of the air inlet cavity 104. When the medical staff extracts the gas in the air cavity 105, the first quick-release connector at the suction end of the convenient air bag 26 is connected to the second quick-release connector of the air outlet cavity 105, and then all the first cavities 301 are manually inflated or exhausted.
[0082] Preferably, Figure 2 For example, it also includes: a third pneumatic telescopic rod 27, which has a plurality of rods, all of which are fixedly connected to the wearing cap 1, and the third pneumatic telescopic rod 27 is connected to the air inlet cavity 104 and the air outlet cavity 105 through a ventilation tube, and the telescopic end of the third pneumatic telescopic rod 27 is fixedly connected with an elastic pad for providing support to the patient's head.
[0083] In the above scheme, by installing a plurality of third pneumatic telescopic rods 27 behind the patient's head, the support force of the device on the patient's head is increased when the patient is lying flat, thereby increasing the comfort level of the patient when using the device.
