Description

1 TARIFF VISIBLE FROM ALL DIRECTIONS PASSIVE OPTICAL FLUID LEVEL AND APPROXIMATELY INFUSION BOTTLE WITH REMAINING TIME INDICATOR TECHNICAL AREA 5 The invention relates to the inner part of a bottle body used for the intravenous administration of medicinal fluids to patients. Thanks to the integrated optical surface structures created on its surface, transparent or colorless infusions are possible. liquid level from different viewing angles without requiring an electronic sensing system visually prominent and additionally the volume indicated on the bottle is 10 approximate remaining time according to the indicators' predetermined nominal infusion conditions It is related to the infusion bottle, which allows it to be associated with the information. STATE OF THE ART Infusion bottles used in intravenous treatments deliver serum, drug solutions, electrolytes, and other substances to patients. Medical supplies that enable the controlled administration of nutrient solutions and similar liquids. These are the materials. Infusion bottles used for this purpose are usually made of glass or clear polymer. They are made from materials that allow the liquid inside to be observed from the outside. It has a light-transmitting structure that allows it to provide light. Therefore, it is especially suitable for low lighting conditions. 20 under these conditions, when viewed from a distance, or in environments where reflection is intense, the liquid level It may not be easily distinguishable by the user. During treatment, healthcare personnel will periodically check the amount of liquid remaining in the bottle. to check, monitor the completion of the infusion and add new 25 if necessary. The infusion bottle must be changed promptly. In hospital settings, infusion... The bottles are usually mounted on suspension systems located above the patient's lying level. It is hanging. It is appropriate for healthcare personnel to approach the bottle to check it. They may need to look for a different perspective or examine the bottle from different angles. The bottle Light reflections on its surface, different light sources in the environment, and the transparent liquid on the glass 30 or exhibiting an optical appearance similar to a transparent polymer, the liquid and the empty part of the bottle This makes it difficult to discern the boundary between them. Current technology aims to address this problem through electronic sensing systems and various other methods. Auxiliary indicator solutions have been developed. 2 EP1722204A1 was identified in the literature search conducted on the known state of the art. In patent application number [number], optical sensors are used to monitor fluid in an infusion system. A mechanism for determining the level is described. In the system mentioned... the presence or absence of liquid, optical sensor, electronic control board and light-proof housing It is detected with the help of this. Thus, the liquid level can be determined electronically. 5 However, this solution requires an electronic sensor, power source, and control circuit. a liquid that can be passively seen by taking advantage of the structural properties of the infusion bottle It does not explain how to create the level. CN2762080Y was identified in a literature search conducted in the known state of the art. In utility model document number [number], it is stated that the liquid level in the infusion bottle can be more easily adjusted. a ruler or indicator placed on the outside of the bottle for readability The reading element is explained. The bottle structure in the system mentioned in this document. It is not being changed, only the current fluid level is being made easier to read from the outside. An additional device is used to assist. Also, the bottle is mentioned in the document. by altering the optical properties of its body or by using the difference in refraction between the liquid and the air 15 No surface geometry providing environmental visibility is described. On the other hand, the volume markings and scales found on existing infusion bottles, However, this function is only effective in cases where the liquid level can be primarily discerned by the user. This is because the transparent liquid and the transparent bottle material exhibit similar optical properties. The problem of not being able to clearly distinguish the liquid-air interface due to this reason persists, 20 Current solutions mostly address this problem using electronic sensors or devices added to the bottle afterwards. They are trying to resolve it with the help of auxiliary elements. Current infusion bottles do not indicate to the patient or caregiver approximately how long the infusion will last. There is also usually a passive indicator that makes it easy to understand that it will be completed later. It is not available. The fact that only volume information is found on the bottle is concerning for 25 people without health education. It may not be meaningful enough for one person. However, the actual end of the infusion The duration depends on the flow rate adjustment made by healthcare personnel, the drip factor of the serum set, and the bottle. depending on the patient's height, the patient's lying position, vascular resistance, and the condition of the tube and similar variables. Therefore, the time values ​​shown on a passive bottle are different. 30 is not a precise measurement, but only an approximate reference based on nominal conditions. available. For the reasons listed above, the level of the clear infusion fluid depends on the structural and optical properties of the bottle itself. its distinctive features, allowing the level to be seen when viewed from different angles 3 facilitating, requiring no electronic equipment, and providing approximate remaining time information when needed. A new infusion bottle is needed that provides this. THE PURPOSE OF THE INVENTION The main purpose of the invention is to create transparent or translucent infusion vials containing transparent or translucent material. The level of the colorless infusion fluid cannot be detected by any electronic detection system or external... enabling the user to perceive it more easily without the need for auxiliary equipment. The goal is to create an infusion bottle. The purpose of the invention is to create a design on the inner surface of the infusion bottle that is integrated with the bottle body. Thanks to their optical surface structures, visible light can pass between the liquid and air contact areas. by creating a difference in refraction and / or light reflection, the liquid level appears to have a distinct optical level. The goal is to make it appear as a border. The other purpose of the invention is to spread the optical effect created around the bottle, thereby affecting the liquid. the level not only from a particular point of view but also from different environmental aspects of the bottle The goal is to make it easily visible. 15 Another aim of the invention is to replicate the meniscus effect occurring on the liquid surface using optical surface structures. by strengthening it, the liquid-air interface becomes more defined, thus increasing the liquid level. The aim is to make them easier to distinguish from a distance or under different lighting conditions. Another purpose of the invention is to use an electronic sensor to make the liquid level visible. camera, light source, power source, paint, chemical indicator, bonded optical element 20 a completely passive level that does not require any additional components or similar features The goal is to provide a display system. Another objective of the invention is to enable the production of optical surface structures together with the bottle body. Thanks to this, it is easy to manufacture, low-cost, and does not require additional assembly. The goal is to obtain a structure compatible with infusion bottle manufacturing methods. 25 Another purpose of the invention is to integrate volume indicators located on the bottle body. Thanks to the approximate remaining time indicators that can be used, the predetermined nominal According to the infusion conditions, the user is informed about the remaining time until the completion of the infusion. The aim is to provide reference information. 4 Another purpose of the invention is to allow healthcare personnel to monitor infusion levels. by reducing the need to approach the bottle or seek different perspectives for the purpose of monitoring the infusion. The goal is to provide an infusion bottle that facilitates, improves patient safety, and enhances ease of use. The structural and characteristic features and all the advantages of the invention are given in the figures below.

Bottle body (2) is made of glass, polyethylene terephthalate (PET), polypropylene (PP), 10 polyethylene (PE), cyclic olefin polymer (COP), cyclic olefin copolymer (COC), or infusion They can be produced from similar transparent or semi-transparent materials suitable for use with liquids. and can be produced in different volumes and geometries depending on the intended use. Bottle body (2); inner surface (3), outer surface (13), bottle neck (16), hanger connection section (17) and outlet 15 preferably a single-piece structure including the mouth (18), but if desired it can be a multi-piece structure can be created. The basic element of the invention is the formation of (3) on the inner surface of the bottle body (2) that comes into contact with the liquid. These are optical surface formations (4). The mentioned optical surface formations (4) are inside the bottle body. extending uninterruptedly along its entire circumference or in succession It can be formed to consist of numerous repeating optical structures. Optical surface 20 formations (4); preferably in the form of microchannels (5) and / or prismatic protrusions (6) It is created using the following elements: grooves, ridges, microprisms, microlens arrays, refractive surfaces, reflective surfaces, Fresnel-type surfaces, zigzag geometries, herringbone patterns, It can also take the form of curved surfaces or various combinations thereof. The aforementioned The dimensions, depths, angles, spacing, and orientations of the structures affect the optical properties of the bottle material. properties, the refractive index of the infusion fluid and the desired optical visibility The values ​​can vary depending on the context. In one application of the invention, optical surface formations (4) are placed at different angles to each other. It is in the form of prismatic projections (6) containing the first optical surface (19) and the second optical surface (20). The first optical surface (19) and the second optical surface (20) receive light rays coming from different directions (22) 30 By reflecting the liquid in different directions, people looking at the bottle from various angles can see the liquid level. It makes it easier. Optical surface formations (4) are horizontal, vertical, inclined, helical, cross or interconnected around the bottle. It can extend in the intersecting directions. In one application, microchannels (5) 6 In one application, it forms circumferential rings, while in another, it runs vertically along the bottle. It can extend in one application, and in another, by using groups of channels that intersect at different angles. Multi-directional optical visibility can be provided. Optical surface formations (4) allow the flow of liquid. A shallow and rounded passage that will not obstruct or leave residue inside the bottle. It can be designed to have regions (21). 5 To make it easier to determine the amount of liquid remaining on the outer surface (13) of the bottle body (2). Volume indicators (14) can be found for this purpose. Volume indicators (14) are printed, laser Indicator markings (25) in the form of marking, recessed, embossed or integrated into the bottle body. It can be created. In addition, on the outer surface (13), at least one predetermined nominal Approximate remaining time indicators (15) prepared according to infusion flow rate are also included. It can receive. The approximate remaining time indicators (15) are based on a single nominal flow rate. Multiple indicators corresponding to different nominal flow rates can be configured. It can also be implemented in the form of a column. The invention does not involve the subsequent mounting of any optical component, sensor, or indicator element onto the bottle. There is no need to do it. Optical surface formations (4), production of bottle body 15 It is created through geometries that are directly processed onto the mold surface during the process. Glass In bottle applications, optical surface geometries are processed into glass forming molds by hot shaping. It is transferred to the bottle during the process of filling the mold surface of the glass, and in polymer-based bottles, injection molding, injection-stretch-blow molding, extrusion blow molding, injection blow molding, obtained by pressing or similar production methods, integrated with the bottle body 20 Thus, optical surface formations (4) become an integral part of the bottle body. Additional items arriving include adhesive, optical film, prismatic parts, paint, coating, and chemical indicators. or the use of electronic components is not required. Once the bottle is produced, it is available. sterilization, filling, capping and packaging, as in infusion bottle production processes. The following operations can be performed. 25 When the infusion fluid (9) is filled into the infusion bottle (1), the body of the bottle (2) is filled with fluid. between the contact part (7) and the empty part (8) that is in contact with the air or gas environment A difference in optical behavior occurs. This is due to the fracture between the bottle material and the infusion fluid. reflection properties, refractive and reflection properties between the bottle material and air. Since they are different, the optical surface formations (4) are the liquid contact region (23) and the air contact region 30 (24) different light refraction, light reflection, light scattering or brightness occurs on it. This difference is due to the optical effect of the meniscus region (12) formed on the liquid surface (10). together they become more pronounced and the liquid level forms a circumferential line extending around the bottle. The level limit (11) can be visually perceived by the user. Thus, the liquid level 7 easily seen not only from a specific front face, but also from different circumferential aspects of the bottle. It can be seen. Volume indicators (14) located on the outer surface of the bottle (13), together with the environmental level limit (11). This allows for the approximate determination of the remaining liquid amount by evaluation. On the outer surface of the bottle body (13), in addition to the volume indicators (14), approximately the remaining 5 There are time indicators (15). The approximate remaining time indicators (15) are shown in advance. based on a defined nominal infusion rate or a standard drip rate is prepared. Approximate remaining time indicators (15), values ​​in minutes or hours. These indicators may include the time remaining until the completion of the infusion. It gives a general idea about the approximate remaining time indicators (15), the actual 10 of the infusion. It does not measure completion time. These indicators are only relevant to predetermined nominal conditions. It provides a general time reference based on. Thanks to this structure, the level of the infusion fluid can be monitored without any electronic sensor, power source, camera, light source, paint, chemical indicator or optical aid added to the bottle afterwards Liquid optical surface formations integrated solely with the bottle body, without the use of any elements. 15 and becomes distinctive thanks to its different optical behavior in air environments and This allows for reliable monitoring of the infusion level from different perspectives.
