Since the zero point positioning line 5 must be aligned with the patient's fourth intercostal mid-axillary line during the measurement process, and the position of the fourth intercostal mid-axillary line varies depending on the patient's body shape, the most commonly used central venous pressure measuring device on the market is a hanging type, which is far away from the patient's body when used. When aligning the position of the patient's fourth intercostal mid-axillary line, visual inspection is usually used, resulting in inaccurate positioning and deviation in the measurement results, or by using another It is very inconvenient to use tools such as a level to position. During use, the measuring instrument of the present application has one end of the support frame 1 placed between the patient's body and the bed, and the position is fixed and naturally kept horizontal. The bearing section 15 can be leaned against the side of the patient's body. When the medical staff confirms the position of the patient's fourth intercostal axillary midline, they can directly align the zero point positioning line 5 with the patient's fourth intercostal axillary midline by sliding the lifting adjustment frame 2. Not only is the adjustment process simple and fast, but the operation is also convenient, making the measurement results more accurate. The infusion set fixing frame 3 vertically fixes the infusion set, and a scale line 4 is set on the surface of one side of the infusion set fixing frame 3 to display the measurement results of the patient. Among them, the infusion set fixing frame 3 can be fixed on the surface of the adjustment frame 2. The structure is complete and more stable, and a detachable infusion set fixing frame 3 can be set on the surface of the adjustment frame 2, which is more convenient for disassembling and assembling the infusion set. The infusion set fixing frame 3 is set on the side surface away from the support frame 1, which is convenient for observing the measurement results and also convenient for installing and disassembling the infusion set. When further used, the support section 14 is placed under the patient. Since the support section 14 is a thin plate-shaped structure, it avoids discomfort to the patient. The support section 14 is further placed between the patient and the bed. The angle α between the one side surface of the support section 14 and the one side surface of the bearing section 15 is a right angle. The entire measuring device is naturally kept horizontal, and the bearing section 15 can be leaned against the side of the patient's body. The medical staff should confirm the patient's fourth intercostal mid-axillary line position.The zero-point positioning line 5 can be quickly aligned with the patient's fourth intercostal space mid-axillary line by simply sliding the lifting adjustment frame 2. This not only makes the adjustment process simple and fast, but also convenient to operate, making the measurement results more accurate. Furthermore, the above solution can be further configured such that, in order to facilitate the storage of the measuring instrument, a hinged structure can be provided between the support section 14 and the load-bearing section 15.

[0025] Please refer to Figures 2 to 4 As shown, specifically, the adjustment frame 2 includes a frame body 7 with through-holes 6 formed at both ends and a fixing pin 8 detachably connected to the frame body 7. An infusion set fixing frame 3 is provided on the surface of the frame body 7. A zero point positioning line 5 is provided on the surface of the frame body 7. The frame body 7 is sleeved on the surface of the support frame 1 through the through-hole 6 and slides up and down along the surface of the support frame 1. A fixing port 9 is provided on one side surface of the frame body 7. The fixing port 9 is perpendicular to and communicates with the through-hole 6. An internal thread is formed in the fixing port 9. The fixing pin 8 is screwed into the fixing port 9. An external thread 10 that matches the internal thread is formed on the surface of the fixing pin 8. When the height of the zero point positioning line 5 needs to be adjusted, the fixing pin 8 is first extended out of the fixing port 9 through the corresponding The mutually compatible internal and external threads 10 are unscrewed so that the frame 7 can slide up and down along the support frame 1 to achieve height adjustment. As the frame 7 slides, the infusion set fixing frame 3 and the zero point positioning line 5 set on the frame 7 are also driven to rise or fall. When the zero point positioning line 5 is aligned with the patient's fourth intercostal axillary midline position, the fixing pin 8 is tightened into the fixing port 9 through the internal and external threads 10. Since the fixing port 9 is perpendicular to and connected to the through port 6, one end of the fixing pin 8 is abutted against the surface of the support frame 1 to fix the position of the frame 7, further realizing the height adjustment of the frame 7, and finally realizing the accurate, convenient and fast alignment of the zero point positioning line 5 with the fourth intercostal axillary midline position at different heights.

[0026] Please refer to Figure 4 As shown, specifically, there are two fixing ports 9, which are symmetrically arranged on both sides of the frame 7. The two fixing pins 8 are screwed in or out of the fixing ports 9 through the internal threads and external threads 10 that adapt to each other. The mutual cooperation of the two fixing pins 8 makes the frame 7 more firmly fixed on the support frame 1, and when the position of the frame 7 is fixed, it naturally remains horizontal and does not tilt, and the measurement result is more accurate.

[0027] Please refer to Figure 2 as well as Figure 5As shown, specifically, the top edge of the support frame 1 is hinged to the limit plate 11, that is, one side of the limit plate 11 is hinged to the top edge of the support frame 1. When the limit plate 11 is folded to form a continued upward extension section of the top of the support frame 1, the frame body 7 can be removed from the top of the support frame 1, so as to facilitate its replacement or maintenance. When one side of the limit plate 11 is hinged to one side edge of the support frame 1 and folded to be perpendicular to the surface of the support frame 1, the limit plate 11 prevents the frame body 7 from being removed from the top of the support frame 1, thereby ensuring the structural integrity.

[0028] Please refer to Figure 1 As shown, specifically, the surface of one end of the infusion device fixing frame 3 is fixed or integrally formed and arranged on the surface of the adjustment frame 2 away from the support frame 1, and the structure is more stable. The infusion device fixing frame 3 is used to fix the infusion device pipeline. The infusion device pipeline is in a vertical state when fixed on the infusion device fixing frame 3. It is arranged on the surface of the adjustment frame 2 away from the support frame 1 to prevent the infusion device from being bent, and the measurement is more accurate and convenient. Further, the surface of one end of the infusion device fixing frame 3 can be fixed or integrally formed and arranged on the surface of the frame body 7 away from the support frame 1.

[0029] Please refer to Figure 6 As shown, specifically, one end of the infusion set fixing frame 3 is detachably arranged on the top surface of the adjusting frame 2. Preferably, an insertion port 16 is extended inwardly on the top surface of the adjusting frame 2, and an insertion portion 17 adapted to the shape of the socket is formed at one end of the infusion set fixing frame 3 near the top of the adjusting frame 2. When the insertion portion 17 is inserted into the insertion port 16, the infusion set fixing frame 3 is fixed to the top position of the adjusting frame 2, and the infusion set pipeline will not be bent after being fixed on the infusion set fixing frame 3. Furthermore, one end of the infusion set fixing frame 3 can be detachably arranged on the top surface of the frame body 7. In this way, during use, when the infusion set pipeline needs to be removed or installed, the infusion set fixing frame 3 can be first removed from the support frame 1, and then the infusion set pipeline can be fixed on the infusion set fixing frame 3 or removed from the infusion set fixing frame 3, and then the support frame 1 can be stored. This increases the operating space during the installation and removal of the infusion set pipeline, making it more convenient to use.

[0030] Please refer to Figure 1 、 Figure 2 as well as Figure 5 and Figure 6 As shown, specifically, a through groove 12 is vertically opened on the side surface of the infusion set fixing frame 3 away from the support frame 1, and the opening edge of the through groove 12 is symmetrically fixed with blocks 13 near the top and bottom. Since the pipeline of the infusion set is a hose, it can be directly placed in the through groove 12, and a slight press is performed on the position where the block 13 is set. The block 13 limits the infusion set pipeline in the through groove 12 to prevent it from falling out.
