Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary devices, and in particular to a position adjustment device for central venous pressure monitoring. Background Art

[0002] The contents of this section merely provide background information related to the present application and may not constitute prior art.

[0003] Central venous pressure (CVP) refers to the pressure of blood flowing through the right atrium and the thoracic segments of the superior and inferior vena cava. In clinical practice, the patient's CVP is generally measured by electronic measurement to facilitate real-time monitoring of whether the patient's CVP is normal.

[0004] In the related technology of measuring CVP by electronic measurement method, CVP reading needs to be generated with the help of pressure sensor. On this basis, in order to ensure the accuracy of CVP measured by pressure sensor as much as possible, the pressure sensor must be in the same horizontal plane with the fourth intercostal space of the patient's mid-axillary line (that is, right atrium). Therefore, the position of pressure sensor needs to be adjusted before each measurement to ensure the correct position of pressure sensor.

[0005] In known clinical practice, the position of the pressure sensor is generally adjusted manually by medical staff. Specifically, during the actual adjustment, the position of the pressure sensor is confirmed by the medical staff's naked eye observation, and then the medical staff manually fixes the pressure sensor to the target position (such as the patient's body, arm, or bed rail of the patient's bed).

[0006] However, in this method, since the entire adjustment process is manually completed by medical staff, not only is the process cumbersome and labor-intensive, but the position of the pressure sensor observed by the medical staff's naked eyes may not be accurate, which may affect the accuracy of the CVP measurement results.

DETAILED DESCRIPTION

[0041] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meanings understood by persons with ordinary skills in the field to which this application belongs. The words "first", "second" and similar words used in the specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0042] An embodiment of the present application discloses a position adjustment device for central venous pressure monitoring. The position adjustment device disclosed in the embodiment of the present application can adjust the position of a pressure sensor 40 for measuring central venous pressure (CVP), in order to simplify the process of adjusting the position of the pressure sensor 40, reduce the labor intensity of medical staff, and improve the accuracy of the position of the pressure sensor 40 after the adjustment.

[0043] Please refer to Figure 1 and Figure 2 ,in, Figure 1shows a schematic structural diagram of an exemplary position adjustment device disclosed in an embodiment of the present application, Figure 2 for Figure 1 The enlarged view of the local structure of the position adjustment device is shown. In general, the position adjustment device disclosed in the embodiment of the present application may include a carrier 10, a drive assembly 20, an indication component 30 and a pressure sensor 40 for detecting CVP.

[0044] In the embodiment of the present application, the carrier 10 is used to provide a carrier for installing components such as the indicating component 30 and the pressure sensor 40. Furthermore, the carrier 10 can be a plate-shaped member in a horizontal state. In addition, the carrier 10 can move along a first direction to change the position of the carrier 10 in the first direction.

[0045] It is worth noting that the first direction mentioned in the embodiment of the present application can be understood as a vertical direction, that is, Figure 1 and Figure 2 In other words, by moving the carrier 10 along the first direction, the position of the carrier 10 in the vertical direction can be changed. The second direction to be described below in the embodiment of the present application is a direction perpendicular to the first direction, which can also be understood as Figure 1 and Figure 2 The x-axis direction shown in FIG. 1 is the direction perpendicular to the first direction and the second direction. Figure 1 and Figure 2 The y-axis direction is shown in FIG.

[0046] The driving assembly 20 is used to drive the carrier 10 to move along the first direction. Preferably, the driving assembly 20 can drive the carrier 10 to move back and forth along the first direction so as to repeatedly adjust the vertical position of the carrier 10. The driving assembly 20 can be, but is not limited to, a conventional linear actuator such as a known electric push rod, a cylinder, or the driving assembly 20 described below in the embodiments of the present application.

[0047] The indicating component 30 is disposed on the supporting platform 10, and is used to emit a light s propagating along the second direction (ie, the x-axis direction). Figure 1 and Figure 2 As shown, the indicating component 30 can be arranged near the edge of the supporting platform 10, and the indicating component 30 is configured to emit a light s propagating along a second direction in a direction away from the supporting platform 10, so as to avoid the light s emitted by the indicating component 30 being blocked by components on the supporting platform 10 and affecting the propagation of the light s.

[0048] Furthermore, the indicating component 30 may be a laser pointer (ie, a laser pen) capable of emitting laser. It is understandable that by using a laser pointer as the indicating component 30, since laser propagation in the air has better reliability, the light s emitted by the indicating component 30 can be reliably propagated along the second direction.

[0049] In the embodiment of the present application, the pressure sensor 40 for measuring CVP is also disposed on the carrier 10 , and the geometric center of the pressure sensor 40 disposed on the carrier 10 is in the same horizontal plane as the light s emitted by the indicating component 30 .

[0050] Through the above configuration, when the position adjustment device disclosed in the embodiment of the present application is actually applied, Figure 5 As shown, the entire position adjustment device can be first fixed near the patient whose CVP needs to be measured. For example, the entire position adjustment device can be fixed on the bed rail of the bed where the patient lies and the end of the indicating component 30 used to emit the light s is directed toward the patient, and the light s emitted by the indicating component 30 is in the same vertical plane as the fourth intercostal space of the patient's mid-axillary line (i.e., the right atrium).

[0051] At the same time, for patients lying on the hospital bed, a sticker 200 that can sense the light s emitted by the indicating component 30 can be pasted on the right atrium of the patient in advance, so as to better judge the position of the light s. For example, when the indicating component 30 is a laser indicator, a laser sensing sticker can be pasted on the right atrium of the patient. Then, the driving component 20 can be used to drive the supporting platform 10 to move in the first direction, so as to drive the indicating component 30 to move in the vertical direction through the supporting platform 10, until the light s emitted by the indicating component 30 hits the sticker 200 pasted on the right atrium of the patient. At this time, the light s emitted by the indicating component 30 and the sticker 200 are in the same horizontal plane, and because the light s emitted by the indicating component 30 and the geometric center of the pressure sensor 40 on the supporting platform 10 are in the same horizontal plane, the purpose of making the pressure sensor 40 and the right atrium of the patient in the same horizontal plane is achieved.

[0052] It can be seen that the position adjustment device disclosed in the embodiment of the present application can achieve mechanical adjustment of the position of the pressure sensor 40 used to measure CVP, which not only simplifies the position adjustment process of the pressure sensor 40, but also helps to improve the accuracy of the position of the pressure sensor 40 after the adjustment, compared with the method of medical staff observing the position of the pressure sensor 40 with the naked eye, and ensure that the pressure sensor 40 and the patient's right atrium are in the same horizontal plane as much as possible, thereby ultimately improving the accuracy of the CVP measured by the pressure sensor 40.

[0053] At the same time, combined Figure 5The content shown is that when patients of different body shapes lie on the bed, the vertical position of the patient's right atrium (also understood as Figure 5 The distance from the right atrium of the patient to the bed surface as shown in the figure is often different. For this reason, the present application adjusts the position of the pressure sensor 40 in the vertical direction by providing a support platform 10 that can move along a first direction, so that patients of various different body shapes can use the position adjustment device disclosed in the embodiment of the present application, thereby effectively improving the practicality of the position adjustment device.

[0054] In some embodiments of the present application, the driving assembly 20 for driving the supporting platform 10 to move along the first direction can be implemented in the following manner.

[0055] Specifically, combined Figure 1 As shown in the figure, the driving assembly 20 may include a substrate 21, a screw rod 22 and a driving motor 23. The substrate 21 may be a vertically arranged plate-like member, and the carrier 10 is slidably connected to the substrate 21, so that the carrier 10 can move along the first direction in a sliding manner. Further, the substrate 21 may be arranged on a side of the carrier 10 away from the indicating component 30, and a sliding groove extending along the first direction is provided on the side of the substrate 21 facing the carrier 10, such as Figure 2 As shown, part of the support platform 10 extends into the slide groove and can slide in the slide groove. In this way, on the basis of enabling the support platform 10 to slide along the first direction, it is beneficial to make the structure of the entire position adjustment device more compact.

[0056] The screw rod 22 is rotatably disposed in the slide groove of the base plate 21, the axial direction of the screw rod 22 extends along the first direction, and the screw rod 22 passes through the portion of the carrier 10 extending into the slide groove and is threadedly connected to the carrier 10, and the drive motor 23 is transmission-connected to the screw rod 22, so as to drive the screw rod 22 to rotate through the drive motor 23. Among them, the drive motor 23 can be disposed at the top of the base plate 21 or other appropriate positions, and the output shaft of the drive motor 23 can be directly transmission-connected to the screw rod 22 or transmission-connected to the screw rod 22 by means of a common transmission mechanism such as a gear transmission, a chain transmission, etc., as long as the drive motor 23 can be used to drive the screw rod 22 to rotate.

[0057] In this way, when the driving motor 23 drives the screw rod 22 to rotate, the support platform 10 can be moved along the axial direction (that is, the first direction) of the screw rod 22 based on the principle of threaded transmission. In addition, by adopting a driving assembly 20 composed of components such as the screw rod 22, compared with conventional linear drives such as electric push rods, it is beneficial to improve the stability of the support platform 10 when moving along the first direction, and help to more accurately control the position of the support platform 10 in the vertical direction, so that the light s emitted by the indicating component 30 can be more accurately hit on the sticker 200 pasted on the patient's right atrium.

[0058] In addition, combined Figure 1 and Figure 5 As shown, in order to facilitate the use of fixing the entire position adjustment device on the bed rail of the hospital bed, a clamp 50 can be set on the side of the substrate 21 away from the support platform 10 or other appropriate positions. In this way, the entire position adjustment device can be installed and fixed only by fixing the clamp 50 on the bed rail of the hospital bed, and it is convenient to remove the position adjustment device later. Of course, in other embodiments of the present application, a level gauge can be added to the clamp 50 to ensure as much as possible that when the clamp 50 is fixed, the substrate 21 is in a vertical state, so that the support platform 10 together with the indicating component 30, the pressure sensor 40 and other components on the support platform 10 are in a horizontal state, so as to further improve the accuracy of the subsequent pressure sensor 40 position adjustment.

[0059] In some embodiments of the present application, continue to refer to Figure 5 As shown, for patients of different body shapes, when the patients lie on the hospital bed, the right atria of the patients of different body shapes are located differently in the vertical direction. Figure 1 and Figure 2 There may also be differences in the position on the y-axis direction (as shown in FIG. 2 ).

[0060] To this end, the present application further arranges the indicating component 30 movably on the carrier 10, so that the indicating component 30 can reciprocate along the third direction (i.e., the y-axis direction) on the carrier 10. In this way, for patients with different body shapes, on the basis of using the carrier 10 to drive the pressure sensor 40 and the indicating component 30 to move synchronously along the first direction to adjust the positions of the pressure sensor 40 and the indicating component 30 in the vertical direction, it is only necessary to cooperate with the movement of the indicating component 30 in the third direction to adjust the position of the indicating component 30 in the horizontal third direction, so that the light s emitted by the indicating component 30 can accurately hit the sticker 200 pasted on the right atrium of patients with different body shapes, further improving the practicality of the position adjustment device.

[0061] In some embodiments of the present application, in order to enable the indicating component 30 to move along the third direction on the supporting platform 10 and simplify the process of adjusting the position of the indicating component 30 in the third direction as much as possible, the position adjustment device disclosed in the embodiment of the present application may also include an adjustment component 60.

[0062] Further, combined with Figure 2 and Figure 3As shown in the content, the adjustment component 60 may include a guide rail 61 and a guide rail clamp 62. Among them, the guide rail 61 is arranged on the carrier 10, and the guide rail 61 extends along the third direction, the guide rail clamp 62 is slidably connected to the guide rail 61, and the indicating component 30 is arranged on the guide rail clamp 62. Preferably, the guide rail clamp 62 can adopt a manual guide rail clamp. For this type of guide rail clamp 62, under normal circumstances, the guide rail clamp 62 and the guide rail 61 are slidably matched, and the guide rail clamp 62 tightly holds the guide rail 61, so that the guide rail clamp 62 cannot slide on the guide rail 61, thereby achieving the purpose of locking the position of the indicating component 30; accordingly, when it is necessary to slide the guide rail clamp 62 along the guide rail 61 to adjust the position of the indicating component 30 in the third direction, it is only necessary to operate The handle of the guide rail clamp 62 is used to release the guide rail clamp 62 from gripping the guide rail 61. The guide rail clamp 62 can then drive the indicating component 30 to slide synchronously on the guide rail 61. When the indicating component 30 reaches the target position (that is, the light s emitted by the indicating component 30 hits the sticker 200 pasted on the patient's right atrium), the guide rail clamp 62 is operated again to grip the guide rail 61, thereby locking the position of the indicating component 30 again to prevent the indicating component 30 from shifting. The operation is simple and convenient.

[0063] Further, in order to facilitate the disassembly and assembly of the indicating component 30, as Figure 3 As shown, the adjustment assembly 60 may further include a clamping member 63 disposed on the top surface of the guide rail clamp 62, and the clamping member 63 is provided with a clamping groove 631 adapted to the indicating member 30, and the indicating member 30 is removably clamped in the clamping groove 631. For example, when the indicating member 30 is a laser pointer, considering that the laser pointer is usually cylindrical, the clamping groove 631 may be an arc-shaped groove open upward to improve the stability of the indicating member 30 after being clamped in the clamping groove 631. In this way, when the indicating member 30 needs to be installed on the guide rail clamp 62, it is only necessary to clamp the indicating member 30 into the clamping groove 631 of the clamping member 63. Conversely, the indicating member 30 can also be conveniently removed from the clamping groove 631, and the operation is simple and convenient.

[0064] Combination Figure 2As shown in the content, in actual implementation, the support platform 10 can be a stepped plate-like member. Specifically, the support platform 10 can include a first support portion 11 and a second support portion 12, and the first support portion 11 is higher than the second support portion 12. At this time, components such as the pressure sensor 40 can be arranged on the top of the first support portion 11, and related components of the adjustment assembly 60 can be arranged on the top of the second support portion 12, so that when the indicating component 30 is snapped into the snap-in groove 631 of the snap-in component 63, the light s emitted by the indicating component 30 can be in the same horizontal plane with the geometric center of the pressure sensor 40, and it helps to optimize the structure of the position adjustment device, making the structure of the position adjustment device more compact and beautiful.

[0065] Considering that the pressure sensor 40 arranged on the support platform 10 often needs to be connected to external equipment and patients using cables or catheters and other components during actual use, if the cables or catheters and other components led out from the pressure sensor 40 are not properly managed, it may cause the cables or catheters and other components to become entangled with each other, which is not conducive to medical staff to sort out the origins of the cables or catheters and other components.

[0066] To this end, combined Figure 2 and Figure 4 As shown in the content, in some embodiments of the present application, a wire fixing plate 70 can also be set on the top of the carrier 10 (specifically the first carrier part 11) located on both sides of the pressure sensor 40, and a plurality of wire fixing grooves 71 open upward are set on the wire fixing plate 70. Since general components such as cables or conduits are columnar, the wire fixing grooves 71 on the wire fixing plate 70 can be arc-shaped grooves open upward. In this way, when the pressure sensor 40 is installed on the first carrier part 11 of the carrier 10, a single cable or conduit or other component led out from both ends of the pressure sensor 40 can be clamped in a single wire fixing groove 71 of the corresponding wire fixing plate 70, so as to effectively manage the components such as cables or conduits.

[0067] It is understandable that in actual clinical practice, while performing CVP monitoring, there may be a need to measure multiple physiological parameters such as the patient's arterial pressure, in which case there may be a need to use more pressure sensors 40. To this end, in some embodiments of the present application, when multiple pressure sensors 40 are needed, multiple pressure sensors 40 can be arranged in a line on the first bearing portion 11 of the bearing platform 10. At this time, the multiple wire fixing grooves 71 on the wire fixing plate 70 can be arranged in sequence along the arrangement direction of the multiple pressure sensors 40, so that the multiple wire fixing grooves 71 on the wire fixing plate 70 can be used to fix the cables or catheters and other components led out from the multiple pressure sensors 40, respectively, so as to achieve batch management of the cables or catheters and other components led out from the multiple pressure sensors 40.

[0068] On this basis, for CVP monitoring, in order to enable the pressure sensor 40 to obtain accurate CVP for a long time, the pressure sensor 40 often needs to be replaced regularly. To this end, in some embodiments of the present application, the pressure sensor 40 is detachably disposed on the first bearing portion 11 of the bearing platform 10.

[0069] Furthermore, in order to simplify the disassembly and assembly process of the pressure sensor 40, a fixing belt 80 corresponding to the pressure sensor 40 can be provided on the carrier 10, wherein the fixing belt 80 can be a flexible elastic belt. In addition, the first end of the fixing belt 80 is fixedly connected to the first bearing part 11 of the carrier 10. For example, the first end of the fixing belt 80 can be fixed to the first bearing part 11 of the carrier 10 by means of fasteners such as screws, so that the fixing belt 80 is detachable as a whole, and the second end of the fixing belt 80 is detachably connected to the first bearing part 11 of the carrier 10. For example, the second end of the fixing belt 80 can be connected to the first bearing part 11 of the carrier 10 by means of detachable parts such as Velcro, and a space suitable for accommodating the corresponding pressure sensor 40 is formed between the fixing belt 80 and the first bearing part 11 of the carrier 10. In other words, when the pressure sensor 40 needs to be fixed on the first bearing part 11 of the bearing platform 10, the second end of the fixing belt 80 is first removed, and the pressure sensor 40 is placed on the first bearing part 11. Then, the second end of the fixing belt 80 can be passed around the top of the pressure sensor 40 and connected to the first bearing part 11, thereby temporarily fixing the pressure sensor 40 to limit the freedom of the pressure sensor 40 in the vertical direction; conversely, the second end of the fixing belt 80 can be separated from the first bearing part 11 to conveniently remove the pressure sensor 40 for replacement. In addition, since the fixing belt 80 is detachable, it is possible to replace the fixing belt 80 of different sizes and widths according to the size of the pressure sensor 40 to be fixed, so that the fixing belt 80 can reliably fix the pressure sensor 40 without covering the functional buttons and other parts on the pressure sensor 40.

[0070] Furthermore, in combination with the above, since the pressure sensor 40 needs to be replaced regularly, in some embodiments of the present application, Figure 4 As shown in the figure, a reminder card slot 90 corresponding to the pressure sensor 40 is also provided on the first bearing part 11 of the bearing platform 10. For example, the reminder card slot 90 can be provided at the side of the first bearing part 11 and at a position convenient for medical staff to observe, and the reminder card slot 90 can be a slot structure open upward, and a removable reminder card 91 is provided in the reminder card slot 90. In this way, in actual application, information matching the corresponding pressure sensor 40 can be written on the reminder card 91, for example, the model, validity period, replacement period and other information of the pressure sensor 40, so that medical staff can regularly replace the pressure sensor 40 according to the information on the reminder card 91.

[0071] In some embodiments of the present application, in order to facilitate the control of the driving assembly 20, the driving assembly 20 is used to drive the carrier 10 to move along the first direction, such as Figure 1 As shown, the position adjustment device may further include a control panel 100 , which may be disposed on the substrate 21 or at other appropriate locations, and the control panel 100 is communicatively connected with the driving motor 23 of the driving assembly 20 .

[0072] In this way, when the driving assembly 20 is needed to drive the carrier 10 to move along the first direction, the medical staff only needs to press the corresponding button (such as the "up" button or the "down" button) on the control panel 100 to control the driving motor 23 to work through the control panel 100, so as to drive the screw 22 to rotate forward or reverse through the driving motor 23, thereby making the carrier 10 reliably move upward or downward along the first direction. Of course, in other embodiments of the present application, the control panel can also automatically control the driving motor 23 of the driving assembly 20 to work according to the instructions input by the medical staff, so as to realize the function of automatically adjusting the position of the pressure sensor 40, that is, to realize automatic alignment.

[0073] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
