[0028] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after the connection. Furthermore, the directional terms mentioned in the embodiments of this application, such as "inner" and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0032] Currently, factors such as inconsistencies in the zero-point location of central venous pressure (CVP) measurement in clinical practice, the influence of body position changes, individual differences in anatomical structure, and operational errors can all adversely affect CVP measurement results. Commonly used zero-point locations in clinical practice include the level at the 4th intercostal space along the mid-axillary line, 5 cm below the sternal angle, and the upper 1 / 3 of the vertical distance between the anteroposterior diameter of the thorax. Different zero-point choices can lead to variations in measurement results; for example, measurements at the mid-axillary line are approximately 3 mmHg higher than those based on the sternal angle. This inconsistency can affect the accuracy of clinical judgment. Furthermore, when the patient's position changes (e.g., from supine to lateral decubitus), the CVP zero-point location needs to be readjusted; otherwise, measurement errors will increase significantly. For example, CVP measurements at 45° and 90° lateral decubitus positions differ significantly from those in the supine position. This positional dependence increases the complexity and risk of error in measurement. In addition, differences in anatomical structure among patients, such as thoracic morphology and sternal angle position, can lead to inaccurate determination of the zero-point location. For example, traditional zero-point positioning methods may not be accurate enough for obese patients, requiring special measurement methods.
[0033] To address the aforementioned technical problems, this application provides a central venous pressure monitoring horizontal positioning component.
[0034] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a central venous pressure monitoring horizontal positioning component provided in some embodiments of this application. Figure 2 This is a partial schematic diagram of a central venous pressure monitoring horizontal positioning assembly provided in some embodiments of this application. The central venous pressure monitoring horizontal positioning assembly 100 may include: an infusion rod 1, a locking member 2, a support frame 3, a horizontal positioner 4, and a connector 6.
[0035] The infusion pole 1 may include a pole body 11, a base 12, and multiple rollers 13. A hook 14 is provided at the top of the pole body 11 in the height direction of the infusion pole 1, for suspending an infusion bag. The base 12 is located at the bottom end of the pole body 11, and the multiple rollers 13 are located on the surface of the base 12 away from the pole body 11, allowing caregivers to push the infusion pole 1 to move.
[0036] The rod body 11 can be a telescopic component.
[0037] The locking element 2 is detachably connected to the rod body 11. The detachable connection between the locking element 2 and the rod body 11 can be achieved through fasteners, snap-fit connections, or other means; this application does not limit the specific method used.
[0038] The support frame 3 is connected to one end of the locking member 2. The connection between the support frame 3 and the locking member 2 can be a fixed connection or a detachable connection, and this application does not limit this.
[0039] The support frame 3 has a receiving groove 31, and the horizontal locator 4 is disposed in the receiving groove 31. The receiving groove 31 has a first opening 311 and a second opening 312. Specifically, the shape of the receiving groove 31 can be the same as the shape of the horizontal locator 4. For example, the horizontal locator 4 is a cube, and the cross-sectional shape of the receiving groove 31 can also be rectangular.
[0040] The horizontal locator 4 contains an infrared level 5, the light-emitting end of which is directly opposite the first opening 311. This prevents the receiving groove 31 from blocking the light emitted by the infrared level 5, allowing the laser emitted by the infrared level 5 to irradiate the patient's skin.
[0041] The upper surface of the infrared level 5 may be equipped with a switch, which can be used to control the laser to turn on and off.
[0042] Connector 6 is connected to horizontal positioner 4 and is directly opposite the second opening 312. Connector 6 has a slot 61 for engaging the pressure sensor. Thus, after the zero point position is determined by horizontal positioner 4, the pressure sensor can be directly placed in slot 61, allowing for rapid calibration of the pressure sensor and improving the accuracy and reliability of the measurement.
[0043] The operation process of the central venous pressure monitoring horizontal positioning component 100 according to an embodiment of this application is described below:
[0044] First, move the infusion rod 1 to a suitable position, then turn on the infrared level 5 and position the center of the laser point at the zero pressure point. Next, fix the support frame 3 to the plane where the horizontal positioner 4 is located using the locking piece 2. Then, place the horizontal positioner 4 in the receiving groove 31 of the support frame 3. Then, fine-tune the installation position of the locking piece 2 so that the horizontal positioner 4 is positioned at the zero pressure point. Finally, fix the connecting piece 6 on the horizontal positioner 4 and place the pressure sensor in the slot 61.
[0045] According to the embodiment of this application, the central venous pressure monitoring horizontal positioning component 100, by setting a horizontal positioner 4 and connecting the connector 6 to the horizontal positioner 4, can locate the zero pressure point through the horizontal positioner 4. Then, the pressure sensor can be placed in the slot 61 to complete the calibration of the pressure sensor, thereby improving the accuracy and reliability of the measurement. At the same time, the position of the locking member 2 can be adjusted according to different patient postures through the detachable locking member 2, thereby improving the versatility of the central venous pressure monitoring horizontal positioning component 100. Furthermore, the horizontal positioner 4 can move with the infusion rod 1, thereby further improving the versatility of the central venous pressure monitoring horizontal positioning component 100.
[0046] Please continue reading. Figure 1 and Figure 2 In some embodiments, the locking member 2 may include a first connecting portion 21, a second connecting portion 22, a first abutting portion 23, and a first driving portion 24. The first connecting portion 21 has a first engaging member 211 at one end facing the second connecting portion 22, and the second connecting portion 22 has a second engaging member 221 at one end facing the first connecting portion 21. The first engaging member 211 and the second engaging member 221 engage in a snap-fit relationship. The first connecting portion 21 and the second connecting portion 22 enclose a clamping space, and the first abutting portion 23 is disposed within the clamping space. The first driving portion 24 drives the first abutting portion 23 to move towards or away from the rod body 11. Therefore, when it is necessary to fix the locking member 2 to the rod body 11, the rod body 11 can be placed in the clamping space by the cooperation between the first snap-fit member 211 and the second snap-fit member 221. Then, the first abutting part 23 is moved by the first driving part 24 so that the first abutting part 23 abuts against the rod body 11, thus fixing the locking member 2 to the rod body 11. The structure is simple, which helps to reduce the assembly difficulty.
[0047] Please continue reading. Figure 1 and Figure 2 In some embodiments, the first connecting portion 21 is provided with a first sliding groove 212, and the first abutting portion 23 of the first sliding groove 212 is provided with a first guide protrusion, which is slidably disposed within the first sliding groove 212. Specifically, the extending direction of the first sliding groove 212 is the same as the moving direction of the first abutting portion 23. Thus, through the cooperation between the first guide protrusion and the first sliding groove 212, the movement of the first abutting portion 23 can be guided, thereby improving the reliability and stability of the abutment.
[0048] Please continue reading. Figure 1 and Figure 2In some embodiments, the first drive unit 24 may include a first pull ring 241 and a plurality of springs 242. One end of the spring 242 is connected to the side of the first abutment 23 away from the rod body 11, and the other end is connected to the first connecting part 21. The first pull ring 241 is disposed at the end of the first abutment 23 away from the base 12. Thus, when the locking member 2 is connected to the rod body 11, the first pull ring 241 can drive the first abutment 23 to move away from the rod body 11, thereby expanding the clamping space. Then, when the first pull ring 241 is released, the springs 242 can drive the first abutment 23 to move closer to the rod body 11, thereby achieving clamping of the rod body 11. The operation is simple, which helps to improve the work efficiency of nursing staff.
[0049] Please continue reading. Figure 1 and Figure 2 In some embodiments, a first magnetic chuck is provided on the bottom wall of the receiving groove 31, and a second magnetic chuck is provided on the side of the horizontal positioner 4 facing the support frame 3. The first and second magnetic chucks are magnetically attracted to each other. Specifically, the first magnetic chuck can be a magnet, the second magnetic chuck can be a magnet, the first magnetic chuck can be metal, the second magnetic chuck can be a magnet, or the first magnetic chuck can be a magnet and the second magnetic chuck can be metal.
[0050] This reduces the difficulty of assembling the horizontal positioner 4, thus saving nursing staff time.
[0051] Please continue reading. Figure 1 and Figure 2 In some embodiments, the infrared level 5 is detachably connected to the level positioner 4. This facilitates the replacement and maintenance of the infrared level 5, thereby reducing the operating cost of the central venous pressure monitoring level positioning component 100.
[0052] Please continue reading. Figure 1 and Figure 2 In some embodiments, the horizontal locator 4 has a mounting through hole 41. A fixing protrusion 42 is provided at the edge of the mounting through hole 41, and the infrared level 5 is disposed in the mounting through hole 41 and abuts against the fixing protrusion 42. This arrangement is simple in structure, facilitates the disassembly of the infrared level 5, and also helps to reduce the manufacturing cost of the central venous pressure monitoring horizontal positioning component 100.
[0053] Please continue reading. Figure 1 and Figure 2 In some embodiments, the connector 6 is detachably connected to the horizontal positioner 4. This facilitates the replacement and maintenance of the connector 6, thereby reducing the operating cost of the central venous pressure monitoring horizontal positioning assembly 100.
[0054] Please continue reading. Figure 1 and Figure 2 In some embodiments, the horizontal positioner 4 is provided with a guide groove 43. The guide groove 43 has a third opening 431 and a fourth opening 432. The third opening 431 is directly opposite to the second opening 312, and the fourth opening 432 communicates with the third opening 431. The connector 6 is slidably disposed in the guide groove 43 through the fourth opening 432. Thus, the connector 6 is slidably connected to the horizontal positioner 4, and the installation of the connector 6 is simple, thereby improving the work efficiency of nursing staff.
[0055] Please continue reading. Figure 1 and Figure 2 In some embodiments, the support frame 3 and the locking element 2 are connected by rotational damping. Therefore, the angle of the horizontal positioner 4 can be changed directly by rotating the support frame 3, reducing the need for adjustment of the locking element 2 and thus improving the work efficiency of nursing staff.
