Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a multifunctional bedside CVP measurement infusion stand. Background Art

[0002] In the medical care process, infusion therapy and CVP (central venous pressure) measurement are common treatment methods. Among them, CVP measurement is of great significance for evaluating the patient's cardiac function, blood volume and vascular tension.

[0003] Currently, traditional IV stands primarily serve the purpose of hanging IV bottles and providing infusion therapy to patients, representing a single function. Their designs often only consider basic infusion requirements, such as stability and load-bearing capacity, while lacking additional features. Furthermore, most IV stands consist of a simple support rod and hook, offering a relatively simple structure with no adjustment capabilities or a limited adjustment range. CVP monitoring typically requires independent CVP monitoring devices. These devices utilize specialized sensors and measurement technologies to obtain CVP data from patients.

[0004] Furthermore, because CVP monitoring equipment is used separately from IV stands, healthcare professionals may need to set up and calibrate the equipment when performing CVP monitoring, increasing operational complexity and time. Healthcare professionals frequently need to switch between equipment and tools when performing infusion therapy and CVP monitoring, hindering work efficiency. Furthermore, the lack of data integration between traditional equipment and IV stands requires healthcare professionals to manually record and analyze data, increasing workload and the potential for error.

[0005] To this end, the prior art provides a product that combines CVP measurement with an IV stand. For example, Publication No. CN213158408U discloses an IV stand with CVP measurement. This stand includes a vertical rod, a scale plate, and an insert plate. The scale plate is slid to the desired height, and then the insert plate is placed on the back of a recumbent patient to secure the scale plate slid onto the vertical rod. The IV tube is then embedded in the scale plate, and the patient's CVP value can be calculated by comparing the fluid level in the IV tube with the scale on the scale plate. However, this stand has the following drawbacks:

[0006] On the one hand, the above-mentioned infusion stand needs to calculate the CVP value based on the distance between the liquid level of the liquid column and the plug plate, as well as the distance between the patient's mid-axillary line and the plug plate. That is, the CVP value is the distance from the patient's mid-axillary line to the liquid level of the liquid column. This is not only cumbersome to calculate, but also the way of placing the plug plate on the back of a lying patient requires medical staff to assist the patient in moving and lifting the body to cooperate, which brings great inconvenience to patients and medical staff.

[0007] On the other hand, the infusion tube needs to complete infusion and CVP measurement at the same time, which is cumbersome to operate. Moreover, the infusion tube is only fixed by opening a groove on the scale plate. Generally, if the infusion tube is out of the groove, accurate CVP measurement cannot be performed, which creates a workload for medical staff. Utility Model Content

DETAILED DESCRIPTION

[0046] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0047] like Figures 1 to 3 As shown, the multifunctional bedside CVP measurement infusion stand includes:

[0048] The bracket 100 includes a rod 110 and a hanging member 120 . The hanging member 120 is fixed to the upper portion of the rod 110 and is used to hang the infusion container 500 .

[0049] The scale assembly 200 includes a sliding plate 210, a scale plate 220, a reference plate 230, and a fixed knob 240. The sliding plate 210 is slidably disposed on the rod body 110. The fixed knob 240 is threadedly connected to the sliding plate 210 for fixing the sliding plate 210. The scale plate 220 and the sliding plate 210 are hinged to form a fixed channel 2000 between the scale plate 220 and the sliding plate 210. The scale plate 220 is made of a transparent material. The surface of the scale plate 220 is provided with scales 220a arranged from top to bottom. The reference plate 230 is rotatably connected to the sliding plate 210. The reference plate 230 is aligned with the starting scale of the scale 220a.

[0050] The three-way valve 300 is connected to the infusion tube 410 , the measuring strip 420 and the infusion strip 430 respectively. The infusion tube 410 is connected to the infusion container 500 , and the measuring strip 420 is located in the fixed channel 2000 .

[0051] The hanging member 120 on the bracket 100 is used to suspend an infusion container 500, which can be a bottle or bag. The physiological saline solution in the infusion container 500 can be sequentially passed through the infusion tube 410, the three-way valve 300, the infusion strap 430, and the patient's central vein (e.g., the internal jugular vein, the subclavian vein, etc.). When the infusion strap 430 is connected to the measuring strap 420, medical personnel can simply read the scale 220a by referring to the liquid level on the measuring strap 420. Because the reference plate 230 is aligned with the starting mark of the scale 220a, the reference plate 230 can be aligned with the patient's fourth intercostal space, mid-axillary line. At this point, the value on the scale 220a corresponding to the liquid level on the measuring strap 420 is the CVP value. Compared to existing techniques, this eliminates the need for medical personnel to assist with lifting or moving the patient, enhancing patient comfort and satisfaction during treatment. It also reduces the workload of medical personnel and improves work efficiency. Furthermore, the need for calculations is eliminated, effectively improving the accuracy of CVP measurement. Since the infusion strap 430 is clamped in the fixed channel 2000 between the scale plate 220 and the sliding plate 210 , the infusion strap 430 is prevented from moving and affecting the measurement accuracy.

[0052] like Figure 1 As shown, the bracket 100 includes a rod body 110 and a suspension member 120. The suspension member 120 and the rod body 110 are detachably connected. Not only can the suspension members 120 of different structural shapes be installed on the upper portion of the rod body 110, but the scale assembly 200 can also be inserted from the upper portion of the rod body 110, and the scale assembly 200 can be moved along the length direction of the rod body 110. The number of the suspension members 120 can be multiple, and the multiple suspension members 120 are spaced around the axis of the rod body 110, wherein the multiple suspension members 120 can be an integrated structure.

[0053] The bracket 100 further includes a base 130 , which is disposed at the lower portion of the rod 110 and is used to support the rod 110 . The base 130 may be provided with a plurality of rollers to facilitate movement of the bracket 100 .

[0054] The rod body 110 , the suspension member 120 , the base 130 , etc. can be made of high-strength, corrosion-resistant metal materials, such as stainless steel or aluminum alloy, etc. The rod body 110 and the suspension member 120 can be fixed with screws, nuts, clamping devices, etc.

[0055] The manufacturing process of the base 130 is as follows: according to the design drawings, the metal material is cut into the shape of the base 130, and then ground and polished to ensure its flatness and smoothness. Holes are drilled on the base 130 to install the rod body 110 and other fixing devices.

[0056] The manufacturing process of the rod body 110 is as follows: the metal material is cut into the rod body 110 of appropriate length, and threads or mounting holes are processed on the lower part thereof to connect with the base 130. The track position of the scale assembly 200 is marked on the rod body 110 and necessary processing is performed.

[0057] The manufacturing process of the hanger 120 is as follows: one or more hangers are made to suspend the infusion container 500 and the CVP measurement line. The hanger 120 can be designed with an adjustment mechanism to adjust according to the height and weight of the infusion container 500. A hook or clip is installed at the end of the hanger 120 to ensure the infusion container 500 is securely suspended.

[0058] After the base 130, the rod 110, and the hanger 120 are fabricated, the lower portion of the rod 110 is threaded onto the base 130, and the hanger 120 is secured to the upper portion of the rod 110 to assemble the stand 100. Furthermore, auxiliary structures such as handrails can be added to the rod 110 to provide convenient support for the patient when needed. Cushions or wrappings can also be installed on easily accessible areas of the IV stand (such as the handrails and hanging rod) to enhance patient comfort.

[0059] like Figures 1 to 3 As shown, the scale assembly 200 includes a sliding plate 210, a scale plate 220, a reference plate 230 and a fixed knob 240. The sliding plate 210 and the scale plate 220 have the same shape, both L-shaped. Specifically, the scale plate 220 includes:

[0060] A scale plate 221, wherein the outer surface of the scale plate 221 is provided with a scale 220a, and the starting scale of the scale 220a coincides with the lower end surface of the scale plate 221;

[0061] The scale horizontal plate 222 is connected to the lower end surface of the scale vertical plate 221.

[0062] The left side of the scale plate 221 is flush with the left side of the scale plate 222, while the right side of the scale plate 222 protrudes from the right side of the scale plate 221. The three-way valve 300 is located to the right of the scale plate 222. The scale 220a is located on the outer surface of the scale plate 221, and the starting mark of the scale 220a coincides with the lower end surface of the scale plate 221.

[0063] The sliding plate 210 includes:

[0064] A sliding vertical plate 211, the sliding vertical plate 211 corresponds to the scale vertical plate 221;

[0065] The sliding horizontal plate 212 corresponds to the scale horizontal plate 222 , and the sliding horizontal plate 212 is connected to the lower end surface of the sliding vertical plate 211 .

[0066] Similarly, the left side of the sliding vertical plate 211 is flush with the left side of the sliding horizontal plate 212, and the right side of the sliding horizontal plate 212 protrudes from the right side of the sliding vertical plate 211. In this way, the left side of the sliding plate 210 and the left side of the scale plate 220 are hinged. Since the vertical length of the sliding vertical plate 211 is longer than the vertical length of the sliding horizontal plate 212, the right side of the sliding vertical plate 211 and the right side of the scale vertical plate 221 are buckled, that is, the sliding plate 210 and the scale plate 220 are hinged. The hinge along the left side is rotated open to place the measuring strap 420 in the fixed channel 2000 between the sliding plate 210 and the scale plate 220. Then, the right side of the sliding vertical plate 211 and the right side of the scale vertical plate 221 are fastened together so that the sliding plate 210 and the scale plate 220 clamp and fix the measuring strap 420. The scale plate 220 is made of a transparent material, so the liquid level in the measuring strap 420 can be compared with the scale on the outer surface of the scale plate 220 to read the CVP value.

[0067] refer to Figure 2 The inner surface of the sliding plate 210 and the inner surface of the scale plate 220 are opposite to each other, and the measuring leather strip 420 is clamped between the inner surface of the sliding plate 210 and the inner surface of the scale plate 220. The fixing channel 2000 is generally L-shaped and includes:

[0068] A vertical channel 2001, the vertical channel 2001 is located between the scale vertical plate 221 and the sliding vertical plate 211;

[0069] The transverse channel 2002 is located between the scale transverse plate 222 and the sliding transverse plate 212.

[0070] The vertical channel 2001 and the horizontal channel 2002 are connected by an arc transition.

[0071] Furthermore, the inner surface of the sliding plate 210 and the inner surface of the scale plate 220 are respectively provided with concave surfaces. When the two concave surfaces are in contact with the inner surface of the sliding plate 210 and the inner surface of the scale plate 220, the fixed channel 2000 is formed. Therefore, the measuring leather strip 420 can be placed on the concave surface of the inner surface of the sliding plate 210 first, and then the inner surface of the sliding plate 210 and the inner surface of the scale plate 220 are fixed in contact with each other by snapping. At this time, the concave surfaces of the inner surface of the sliding plate 210 and the inner surface of the scale plate 220 respectively wrap the measuring leather strip 420, that is, the measuring leather strip 420 is pushed into the fixed channel 2000, effectively preventing the measuring leather strip 420 from shifting or detaching, thereby improving the measurement accuracy of the CVP value.

[0072] like Figure 2 and Figure 3 As shown, the sliding plate 210 is provided with a through hole 213 through which the rod body 110 passes. Before the upper part of the rod body 110 is installed with the suspension member 120, the rod body 110 utilizes the through hole 213 of the sliding plate 210 on the upper part to enable the scale assembly 200 to move along the length direction of the rod body 110, and then is fixed by the fixing knob 240, wherein the fixing knob 240 is threadedly connected to the sliding plate 210 until it abuts against the rod body 110, so as to achieve the fixation of the scale assembly 200 on the rod body 110.

[0073] refer to Figure 1 The end of the measuring strip 420 away from the three-way valve 300 is an open end, which is used to connect to the atmosphere. The open end of the measuring strip 420 slightly protrudes from the upper surface of the sliding vertical plate 211. Preferably, the open end of the measuring strip 420 is provided with a breathable sealing membrane, wherein the breathable sealing membrane can be a WERS (Weiers PF202) breathable sealing membrane, which has good air permeability and strong hydrophobicity. While sealing and filtering bacteria, air can also flow freely.

[0074] like Figure 2As shown, the reference plate 230 is a retractable reference plate. It corresponds to the starting scale and is rotatably connected to the outer surface of the sliding plate 210. Because the starting scale of the scale 220a coincides with the lower end surface of the scale vertical plate 221, and the sliding vertical plate 211 corresponds to the scale vertical plate 221, the reference plate 230 can be hinged to the lower end surface of the sliding vertical plate 211 to align it with the starting scale. The reference plate 230 is designed to align with the patient's fourth intercostal space mid-axillary line. Once aligned, the starting scale is aligned with the patient's fourth intercostal space mid-axillary line, eliminating the need to move or rotate the patient, thereby improving patient comfort. The thickness of the sliding plate 210 is greater than that of the scale plate 220, and the reference plate 230 is hingedly connected to the lower end surface of the sliding vertical plate 211. Therefore, the reference plate 230 can abut and be accommodated on the sliding horizontal plate 212, thereby improving the stability of the reference plate 230 after extension. The reference plate 230 can rotate 360 ​​degrees relative to its connection with the sliding plate 210.

[0075] refer to Figure 4 The reference plate 230 includes a plurality of sub-plate bodies 231, and the plurality of sub-plate bodies 231 are rotatably connected in sequence. Therefore, the plurality of sub-plate bodies 231 can be folded and stored with each other, and the reference plates 230 after storage can also abut against the sliding horizontal plate 212.

[0076] The manufacturing process of the scale assembly 200 is as follows: according to the size of the bracket 100 and the measurement requirements, a sliding plate 210, a scale plate 220, and a reference plate 230 of corresponding sizes are designed and manufactured. The scale plate 220 is made of a transparent material, such as plastic, and clear scales are printed on the outer surface of the scale plate 220 to indicate the CVP value. A through hole 213 for the rod body 110 to pass through is opened on the sliding plate 210. At the same time, concave surfaces are processed on the inner surfaces of the sliding plate 210 and the scale plate 220. When the two concave surfaces abut the inner surfaces of the sliding plate 210 and the scale plate 220, the fixed channel 2000 is formed. The diameter and depth of the fixed channel 2000 should be adapted to the outer diameter of the measuring strap 420 to ensure that the measuring strap 420 can be stably embedded in the fixed channel 2000.

[0077] The left side of the sliding plate 210 and the left side of the scale plate 220 are hinged, and the reference plate 230 is hinged on the lower end surface of the sliding vertical plate 211 to complete the assembly of the scale assembly 200. Afterwards, the rod body 110 is fixed by the through hole 213 of the sliding plate 210 on the upper part, and the fixing knob 240 is used. The hanging member 120 is then installed on the upper part of the rod body 110 to assemble the multifunctional bedside CVP measurement infusion stand. During the assembly process, it is important to ensure that the connections between the various components are firm and reliable without any looseness. Functional testing can also be performed to ensure that the infusion stand can stably hang the infusion container and measure the CVP value, and to check whether the scale on the scale is accurate and clear. Finally, the infusion stand is cleaned and disinfected as a whole to ensure that it meets the hygiene standards for medical equipment.

[0078] The method of using the multifunctional bedside CVP measurement infusion stand is as follows:

[0079] Preparation:

[0080] 1. Patient preparation. Ensure the patient is in a supine position with the body parallel to the bed to minimize the effect of body position on CVP measurement. Also, check the patency of the patient's central venous catheter (CVC) or peripherally inserted central catheter (PICC) and confirm its correct placement.

[0081] 2. Equipment Preparation. Place the IV stand next to the patient's bed, ensuring the base 130 is stable and the rod 110 is vertical. Prepare the infusion container 500 and hang it on the hanger 120. Adjust the height and angle of the hanger 120 as needed. Check that the scale assembly 200, measuring strap 420, and three-way valve 300 required for CVP measurement are complete. Connect the infusion strap 430 to the central venous catheter. Ensure the connection is tight and there are no air or fluid leaks.

[0082] CVP measurement steps:

[0083] 1. Adjust the height of the scale assembly 200: Slide the scale assembly 200 along the rod 110 to the appropriate position, aligning the starting mark of the scale 220a with the patient's fourth intercostal space, the mid-axillary line, which is the "zero point" for CVP measurement. Then, secure the scale assembly 200 with the fixing knob 240. Ensure that the scale assembly 200 is stable and does not easily slide to accurately read the CVP value.

[0084] 2. Connect the infusion tube 410: Connect one end of the infusion tube 410 to the infusion container 500 and the other end to the infusion strap 430 through the three-way valve 300. Open the regulator of the infusion container 500 to allow the liquid to flow into the central venous catheter at a uniform rate.

[0085] 3. Observe the changes in the liquid level in the measuring strip 420: Wait for a while until the liquid level in the measuring strip 420 stabilizes and no longer fluctuates. At this time, observe the scale line corresponding to the measuring strip 420 on the scale. The value indicated by the scale line is the patient's CVP value.

[0086] In summary, the IV stand adopts a modular design, comprising a base, a rod, a suspension member, and a slidable scale assembly 200. The scale assembly 200 slides up and down along the rod and is provided with a fixed channel 2000 for inserting the measuring strap 420. The scale assembly 200 has a printed scale on its outer surface, allowing medical staff to easily adjust the position of the scale assembly 200 to accommodate the measurement needs of different patients.

[0087] CVP is the pressure at the point where the superior and inferior vena cava enter the right atrium and can be directly measured by inserting a central venous catheter. The IV stand uses the fixed channel 2000 and scale of the scale assembly 200 to indirectly measure CVP by observing the height change of the liquid level in the measuring strap 420.

[0088] To enhance ease of use, the IV stand incorporates a variety of auxiliary features. For example, it can be secured to the bedside or bedside table via a clamping device to accommodate various usage scenarios. Components such as the suspension and scale assembly are removable for easy cleaning and maintenance. Furthermore, the IV stand is equipped with the necessary fixings and adjustment mechanisms to ensure stability and accuracy during measurement.

[0089] Clinical Needs: In medical practice, measuring central venous pressure (CVP) is crucial for assessing a patient's cardiac function, blood volume, and vascular tone. However, traditional CVP measurement methods often require complex equipment and cumbersome procedures, making it difficult for healthcare professionals to quickly and accurately perform measurements, especially in bedside settings. Therefore, developing a simple, convenient, and bedside CVP measurement device is crucial. Patient Comfort: Existing IV stands and CVP measurement devices are often bulky, inconvenient to operate, and can cause patient discomfort. The multifunctional, comfortable bedside CVP measurement IV stand designed by this invention aims to improve patient comfort and user-friendly measurement procedures through optimized design and structure. Healthcare Professional Efficiency: Healthcare professionals frequently perform infusions and CVP measurements in their daily work. A multifunctional IV stand that integrates both infusion and CVP measurement can significantly improve their work efficiency, reduce operating time, and reduce workload. Cost-Effectiveness: Compared to complex intelligent devices, the IV stand of this invention utilizes a simple and economical design, reducing production costs and making it affordable for more healthcare institutions, thereby benefiting more patients.

[0090] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention cannot be limited by these embodiments alone. That is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
