Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to an examination bed. Background Art

[0002] Magnetic resonance imaging (MRI) is an auxiliary examination method widely used in modern medicine. During MRI examination, the subject is generally placed on the bed of the examination bed, and then the bed of the examination bed is moved so that the subject moves with the bed to the examination area of ​​the MRI device, so that the subject's part to be examined can be subjected to MRI examination. When performing MRI examination of the subject's lesion, it is sometimes necessary to monitor the subject's breathing at the same time.

[0003] The general way to monitor the subject's breathing is to place a strain gauge on each side of the subject's chest on the examination bed, and connect a belt across the subject's chest to the strain gauges on both sides. When the subject breathes, the movement of the chest pulls the belt to tighten and relax, and at the same time, the stress on the strain gauge connected to the belt will change, causing the resistance value of the strain gauge to change, and then the subject's breathing can be monitored based on the change in the resistance value of the strain gauge.

[0004] It can be seen that the traditional method of monitoring the subject's breathing requires the subject to wear more additional components, which leads to cumbersome operating procedures during monitoring and poor subject experience. Summary of the invention

[0005] Based on this, it is necessary to provide an examination bed to solve the problem that the traditional way of monitoring the breathing of the subject leads to cumbersome operation process and poor subject experience during monitoring. The examination bed can be used to monitor the breathing of the subject, and no additional parts need to be worn on the subject when monitoring the breathing of the subject, so that the operation process during monitoring is simple and the subject experience is improved.

[0010] The above-mentioned examination bed, because the flexible bag is filled with fluid and can protrude from the support surface, when the subject lies on the support surface of the examination bed, the flexible bag will be compressed, and the movement of the subject's chest when breathing will cause the subject's pressure on the flexible bag to change, so that the pressure value in the flexible bag will change synchronously with the subject's breathing. Therefore, according to the change signal of the pressure value in the flexible bag monitored by the pressure monitoring device, the change cycle of the pressure value in the flexible bag is analyzed to obtain the subject's breathing rate. It can be seen from this that when using the above-mentioned examination bed to monitor the subject's breathing, the subject can lie on the support surface of the bed without the need to wear additional components on the subject, so that the operating process during monitoring is simple and improves the subject's experience.

[0045] See also Figure 1 Combination Figure 2 An embodiment of the present application provides an examination bed 100 . The examination bed 100 includes: a bed body 110 , a flexible bag 120 , and a pressure monitoring device 160 .

[0046] The bed body 110 has a support surface 110a. When the examination bed 100 is in use, the support surface 110a is vertically upward and is used to support a subject (not shown).

[0047] The flexible bag 120 is disposed on the bed 110. The flexible bag 120 has an inner cavity 101. The inner cavity 101 of the flexible bag 120 is used to be filled with fluid, so that there is a certain pressure in the flexible bag 120. The fluid is, for example, gas or liquid.

[0048] The material used for the flexible bladder 120 may be rubber, flexible polymer, etc. Since the flexible bladder 120 is made of flexible material, the flexible bladder 120 can change in volume as the pressure of the fluid filled therein changes, thereby expanding or contracting.

[0049] like Figure 1 As shown, when the inner cavity 101 of the flexible bag 120 is filled with fluid, the fluid increases the volume of the flexible bag 120 and expands it, so that the flexible bag 120 can protrude from the support surface 110a. The protruding direction of the flexible bag 120 when protruding from the support surface 110a is along the direction Y of the support surface 110a.

[0050] The pressure monitoring device 160 is connected to the flexible bladder 120 and is used to monitor the pressure in the flexible bladder 120. It is understood that when the fluid filled in the inner cavity 101 of the flexible bladder 120 is gas, the pressure monitoring device 160 adopts an air pressure monitoring device to monitor the air pressure value in the flexible bladder 120. The air pressure monitoring device is, for example, a barometer, an air pressure sensor, etc. When the fluid filled in the inner cavity 101 of the flexible bladder 120 is liquid, the pressure monitoring device 160 can adopt a hydraulic pressure monitoring device to monitor the hydraulic pressure value in the flexible bladder 120. The hydraulic pressure monitoring device is, for example, a hydraulic pressure gauge, a hydraulic pressure sensor, etc.

[0051] When the examination bed 100 is used to monitor the breathing of a subject, first, a fluid is filled into the inner cavity 101 of the flexible bag 120 so that a certain pressure is formed in the flexible bag 120 and the flexible bag 120 protrudes from the support surface 110a. Then, the subject is made to lie on the support surface 110a of the examination bed 100 so that the position of the subject's chest corresponds to the position of the flexible bag 120.

[0052] Since the flexible bag 120 protrudes from the support surface 110a, when the subject lies on the support surface 110a of the examination bed 100, the flexible bag 120 will be compressed. Since the position of the subject's chest corresponds to the position of the flexible bag 120, the movement of the subject's thorax when breathing will cause the subject's pressure on the flexible bag 120 to change, so that the pressure value in the flexible bag 120 will change synchronously with the subject's breathing. Therefore, according to the change signal of the pressure value in the flexible bag 120 monitored by the pressure monitoring device 160, the change cycle of the pressure value in the flexible bag 120 is analyzed to obtain the subject's breathing rate. It can be seen that when using the above-mentioned examination bed 100 to monitor the subject's breathing, the subject can lie on the support surface 110a of the bed body 110, without the need to wear additional components on the subject, so that the operation process during monitoring is simple and improves the subject's experience.

[0053] In addition, when the subject's heart beats, the movement of the heart will produce a recoil effect in the chest, and the movement of the blood will produce a recoil effect throughout the body, so when the subject's heart ejects blood, its gravity will change. Due to the change in the subject's own gravity caused by the subject's heart beat, the subject's pressure on the flexible bag 120 will also change, so that the pressure value in the flexible bag 120 will also change synchronously with the subject's heart beat. Therefore, the change signal of the pressure value in the flexible bag 120 monitored by the pressure monitoring device 160 will be affected by the subject's breathing and heart beat. Usually, the human body has a respiratory rate of 12-20 times / minute and a heart rate of 55-70 times / minute at rest. Therefore, the change signal of the pressure value in the flexible bag 120 monitored by the pressure monitoring device 160 is filtered using a bandpass filter with a passband of 0.2Hz-0.3Hz and 0.75Hz-1.5Hz, respectively, to separate the respiratory wave signal and the cardiac shock wave signal. The breathing rate of the subject can be obtained according to the changing period of the respiratory wave signal, and the heart rate of the subject can be obtained according to the changing period of the cardiac shock wave signal.

[0054] In other embodiments, when the subject lies on the support surface of the examination bed, the position of the subject's abdomen can also be made to correspond to the position of the flexible bag. Then, the movement of the subject's abdomen during breathing will cause the subject's pressure on the flexible bag to change, so that the pressure value in the flexible bag will change synchronously with the subject's breathing. Therefore, according to the change signal of the pressure value in the flexible bag monitored by the pressure monitoring device 160, the change cycle of the pressure value in the flexible bag is analyzed, and the breathing rate of the subject can also be obtained.

[0055] Please refer to Figure 1 In one embodiment, a groove 102 is provided on the support surface 110 a , and the flexible bag 120 is disposed in the groove 102 .

[0056] Specifically, the flexible capsule 120 is disposed in the groove 102. On the one hand, the groove 102 provides an installation space for the flexible capsule 120 and facilitates positioning of the flexible capsule 120 during installation. On the other hand, as described above, when the inner cavity 101 of the flexible capsule 120 is filled with fluid, the fluid will increase the volume of the flexible capsule 120 and expand it, so that the flexible capsule 120 can protrude from the support surface 110a. In this embodiment, since the groove 102 can accommodate the flexible capsule 120, the flexible capsule 120 only needs to partially protrude from the support surface 110a, so that the subject feels relatively flat when lying on the support surface 110a.

[0057] Further, in a specific embodiment, along the direction Y of the support surface 110a, the size of the portion of the flexible bag 120 located in the groove 102 is greater than the size of the portion of the flexible bag 120 protruding from the support surface 110a. Figure 1From the perspective of , that is, the height dimension of the portion of the flexible sac 120 located in the groove 102 is greater than the height dimension of the portion of the flexible sac 120 protruding from the support surface 110a, thereby further making the protrusion of the flexible sac 120 from the support surface 110a smaller, thereby making the subject feel relatively flat when lying on the support surface 110a.

[0058] In other embodiments, the support surface may not be provided with a groove, and the flexible bag is directly disposed on the support surface, so that the entire flexible bag protrudes from the support surface.

[0059] refer to Figure 2 In one embodiment, the examination bed 100 further includes a pressure adjustment device 170, which is connected to the flexible bag 120 and is used to adjust the pressure in the flexible bag 120 so that the flexible bag 120 can maintain a desired pressure value. The pressure adjustment device 170 can be a gas pressure adjustment device or a hydraulic pressure adjustment device. For example, when the fluid is a gas, the pressure adjustment device 170 can be a gas pressure adjustment device. When the fluid is a liquid, the pressure adjustment device 170 can be a hydraulic pressure adjustment device.

[0060] Specifically, the pressure regulating device 170 may be a pressure regulating pump, such as a pneumatic pump or a hydraulic pump. When the fluid is gas, the pneumatic pump may be used as the pneumatic pressure regulating device. When the fluid is liquid, the hydraulic pressure regulating device may be used as a hydraulic pump.

[0061] Please refer to Figure 1 In one embodiment, the bed body 110 includes: a bed board 111 and a bed frame 112. In actual use, the bed frame 112 is located below the bed board 111 to support the bed board 111. The support surface 110a is the surface of the bed board 111, and the subject is supported by the bed board 111. Specifically in this embodiment, the groove 102 is provided on the bed board 111, and the flexible bag 120 is provided in the groove 102, that is, the flexible bag 120 is provided on the bed board 111.

[0062] The bed board 111 can move relative to the bed frame 112 along a first direction X, wherein the first direction X is perpendicular to the direction Y of the support surface 110a. Specifically, in actual use, the direction Y of the support surface 110a is vertically upward, and the first direction X is a horizontal direction. In other words, the bed board 111 can move relative to the bed frame 112 along a horizontal direction.

[0063] When a nuclear magnetic resonance imaging is required, the subject can be placed on the bed board 111 first. The bed frame 112 is kept stationary, and the bed board 111 is moved along the first direction X, so that the subject and the flexible capsule 120 can be moved together with the bed board 111 into the examination area of ​​the nuclear magnetic resonance imaging device. Since the subject and the flexible capsule 120 can be moved together with the bed board 111 into the examination area of ​​the nuclear magnetic resonance imaging device, the subject can test the respiratory rate and heart rate through the flexible capsule 120 and the pressure monitoring device 160 while undergoing the nuclear magnetic resonance imaging examination.

[0064] Of course, it can be understood that the examination bed 100 in this embodiment can also be used to transfer the subject to the examination area of ​​other medical equipment, such as a direct digital X-ray system (DR), a computer tomography device (CT), etc., and is not limited to a magnetic resonance imaging device. Thus, the subject can test the respiratory rate and heart rate through the flexible bag 120 and the pressure monitoring device 160 while undergoing other medical examinations.

[0065] Please refer to Figure 1 In one embodiment, the examination bed 100 further includes a flexible tube 130. One end of the flexible tube 130 is connected to the flexible bag 120, and the other end of the flexible tube 130 is connected to the pressure monitoring device 160, so that the fluid in the flexible bag 120 can flow into the flexible tube 130, so that the pressure monitoring device 160 can monitor the pressure value in the flexible bag 120 through the flexible tube 130.

[0066] Specifically, the material used for the flexible tube 130 may be rubber, flexible polymer, etc. Figure 1 As shown, in this embodiment, one end of the flexible tube 130 is connected to the flexible bag 120, and the other end of the flexible tube 130 is successively passed through the bed board 111 and the bed frame 112 and then connected to the pressure monitoring device 160. The pressure monitoring device 160 is arranged in the control compartment 140 arranged on the bed frame 112. Of course, the pressure monitoring device 160 can also be arranged at other positions of the bed frame 112.

[0067] Since the flexible bag 120 and the pressure monitoring device 160 are connected via the flexible tube 130 , the flexible bag 120 and the pressure monitoring device 160 can move relative to each other through the movement of the flexible tube 130 , and the two can still remain connected while moving relative to each other.

[0068] In the process that the subject moves along the first direction X to the examination area of ​​the nuclear magnetic resonance imaging device together with the bed board 111, the pressure monitoring device 160 and the bed frame 112 can be placed outside the examination area and both can remain motionless. At this time, the flexible capsule 120 can move relative to the pressure monitoring device 160 through the movement of the flexible tube 130, so that the flexible capsule 120 can move along the first direction X to the examination area of ​​the nuclear magnetic resonance imaging device together with the bed board 111 and the subject. It can be seen that when the flexible capsule 120 moves along the first direction X to the examination area of ​​the nuclear magnetic resonance imaging device together with the bed board 111 and the subject, the pressure monitoring device 160 does not need to enter the examination area of ​​the nuclear magnetic resonance imaging, thereby avoiding the influence of the metal material used by the pressure monitoring device 160 on the magnetic field environment of the nuclear magnetic resonance imaging device, and the flexible capsule 120 can still be connected to the pressure monitoring device 160 through the connecting tube 130.

[0069] In other embodiments, when the flexible bag does not need to be used in a magnetic field environment, the pressure monitoring device 160 may also be disposed on the flexible bag or on the bed board.

[0070] In one embodiment, the pressure regulating device 170 is connected to the flexible bladder 120 via the flexible tube 130 . One end of the flexible tube 130 is connected to the flexible bladder 120 , and one end of the flexible tube 130 away from the flexible bladder 120 is connected to the pressure regulating device 170 .

[0071] Specifically, in the present embodiment, the pressure regulating device 170 and the pressure monitoring device 160 share the same flexible tube 130. The examination bed 100 further includes a three-way valve (not shown). The three-way valve is disposed at one end of the flexible tube 130 away from the flexible bag 120. The three-way valve has a first valve port, a second valve port, and a third valve port. The first valve port is communicated with the pressure regulating device 170, the second valve port is communicated with the pressure monitoring device 160, and the third valve port is communicated with one end of the flexible tube 130 away from the flexible bag 120, so that the pressure regulating device 170 and the pressure monitoring device 160 can share the same flexible tube 130 and be connected to the flexible bag 120.

[0072] In this embodiment, the pressure regulating device 170 is disposed in a control chamber 140 disposed on the bed frame 112 . Of course, the pressure regulating device 170 may also be disposed at other positions of the bed frame 112 .

[0073] In the process that the subject moves along the first direction X into the examination area of ​​the nuclear magnetic resonance imaging device together with the bed board 111, the pressure adjustment device 170 and the bed frame 112 can be placed outside the examination area and both can remain motionless. At this time, the flexible capsule 120 can move relative to the pressure adjustment device 170 through the movement of the flexible tube 130, so that the flexible capsule 120 can move along the first direction X into the examination area of ​​the nuclear magnetic resonance imaging device together with the bed board 111 and the subject. It can be seen that when the flexible capsule 120 moves along the first direction X into the examination area of ​​the nuclear magnetic resonance imaging device together with the bed board 111 and the subject, the pressure adjustment device 170 does not need to enter the examination area of ​​the nuclear magnetic resonance imaging, thereby avoiding the influence of the metal material used by the pressure adjustment device 170 on the magnetic field environment of the nuclear magnetic resonance imaging device, and the flexible capsule 120 can still be connected to the pressure adjustment device 170 through the connecting tube 130.

[0074] In other embodiments, the pressure adjustment device 170 and the pressure monitoring device 160 may be respectively equipped with a flexible tube, and the two are respectively connected to the flexible bag through their respective corresponding flexible tubes, so that the pressure adjustment device 170 can adjust the pressure of the flexible bag, and the pressure monitoring device 160 can monitor the pressure of the flexible bag. In addition, the end of the flexible tube corresponding to the pressure adjustment device 170 away from the flexible bag can be inserted into the bed board and the bed frame in turn and then connected to the pressure adjustment device 170.

[0075] In other embodiments, when the bed board does not need to be used in a magnetic field environment, the pressure monitoring device 160 can also be disposed on the bed board.

[0076] Please refer to Figure 1 In one embodiment, the examination bed 100 further includes: a drag chain trough 150 . The drag chain trough 150 is disposed on the bed board 111 and / or the bed frame 112 , and the flexible tube 130 is passed through the drag chain trough 150 .

[0077] Specifically, Figure 1 As shown, in this embodiment, a portion of the drag chain trough 150 is disposed in the bed board 111, and another portion is disposed in the bed frame 112. Since the flexible tube 130 is inserted into the drag chain trough 150, the drag chain trough 150 can limit the position of the flexible tube 130 during the movement of the flexible bag 120 relative to the pressure monitoring device 160 and / or the pressure adjustment device 170 through the movement of the flexible tube 130, so as to keep the flexible tube 130 regular. Moreover, since the flexible tube 130 is inserted into the drag chain trough 150, it can be protected by the drag chain trough 150 to prevent the wear caused by the friction between the flexible tube 130 and the bed body 110.

[0078] Furthermore, if Figure 1As shown, the drag chain trough 150 includes a transverse section 151 extending along a first direction X and a longitudinal section 152 extending along a second direction Y. The second direction Y is the direction of the support surface 110a. Among them, at least two transverse sections 151 are arranged at intervals along the second direction Y. Adjacent transverse sections 151 are connected by longitudinal sections 152. By providing at least two transverse sections 151 and longitudinal sections 152 for connecting adjacent transverse sections 151, the drag chain trough 150 forms a multi-section bending shape, so that the drag chain trough 150 can have a longer total length, which can make the length of the flexible tube 130 passing through the drag chain trough 150 longer, thereby facilitating the flexible bag 120 to move relative to the pressure monitoring device 160 and / or the pressure adjustment device 170. In addition, by providing at least two transverse sections 151 and longitudinal sections 152 for connecting adjacent transverse sections 151, the drag chain trough 150 forms a multi-section bending shape, saving the installation space of the drag chain trough 150.

[0079] Specifically in this embodiment, the transverse section 151 is composed of two sections, and the two sections are both disposed in the bed frame 112 .

[0080] In other embodiments, the drag chain trough may also be provided on only one of the bed board or the bed frame.

[0081] In one embodiment, the examination bed 100 further includes: a tensile layer (not shown). The tensile layer is disposed on the outer surface of the flexible bag 120. The tensile strength of the material used in the tensile layer is greater than the tensile strength of the material used in the flexible bag 120, thereby improving the tensile performance of the flexible bag 120 and preventing the flexible bag 120 from over-expanding.

[0082] The material used for the tensile layer is, for example, tensile fiber, and the tensile layer is connected to the outer surface of the flexible bag 120 by, for example, bonding.

[0083] In one embodiment, the bed 110 has a first position and a second position along the first direction X. The first position and the second position are respectively provided with flexible bags 120, and each flexible bag 120 is correspondingly provided with a pressure monitoring device 160. The first position is used to correspond to the chest of the subject, and the second position is used to correspond to the abdomen of the subject, so that when the subject lies on the support surface 110a, the respiratory rate of the subject at the chest position and the respiratory rate at the abdomen position can be tested respectively.

[0084] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
