Definitions

  • substance in fluid form (normal saline, dissolved antibiotics, etc.) needs to be given to patients using a drip set which will be attached to a saline bottle.
  • the bottle will act as the reservoir for fluid storage.
  • the proposed dispenser bottle has a unique shape in order to facilitate the functionality required as per the invention as depicted in Figs 1, Figs 3, Figs 4 and Figs 5.
  • a floater inside the dispenser bottle as depicted in Figs 2 to Figs 4 will stop air leakage from the dispenser bottle into the drip set when the fluid runs out of the dispenser bottle and thus prevent air entering the patient's blood circulation via the drip set.
  • the accumulated air inside the saline bottle can then flow back into the drip set once the fluid runs out and instead of fluid, air in the bottle will flow into the patient via the drip set.
  • the current invention will overcome the flow of air into the patient via the drip set once the fluid runs out.
  • the invention has two parts, the dispenser bottle and a floater.
  • the floater would be inside the dispenser bottle, and both the dispenser bottle and the floater would have unique shapes as described below.
  • the shape of the dispenser bottle (1) will differ from a normal saline bottle. To identify the top end and the lower end of the dispenser bottle, the inventor demarcates the ends by the structure involved or attached to either end.
  • the top end of the dispenser bottle (1) would be the end that could be hung on a saline bottle stand while in use with the help of the hanger (14).
  • the lower end would be the end where the drip set (27) would be connected to the dispenser bottle (1) through the rubber lid (9) with the aid of the drip set connector (25).
  • the dispenser bottle will take a cylindrical shape. This portion would be called cylinder one (33), and the walls of the cylinder one (33) will run parallel to each other with a uniform diameter from top end till bend one (10), as seen in any conventional saline bottle.
  • the shape of the dispenser bottle will change from a cylindrical shape to a funnel shape with the walls of the dispenser bottle (1) sloping or angulating inwards the dispenser bottle (1) centre line (15).
  • the distance between the dispenser bottle walls will reduce as you move down from bend one (10) to bend two (11).
  • funnel two/floater landing site (7) As you move down from bend two (11) to bend three (12) the continued sloping or angulating inward to the dispenser bottle (1) will continue forming another funnel shaped segment, this portion would be named as funnel two/floater landing site (7) as shown in Fig 1 and Fig 3. The funnel two/floater landing site (7) will form a lesser slope in comparison to funnel one (6).
  • Angle number two (32) would form a larger angle with the centre line (15) than angle one (31).
  • funnel one (6) would be longer in length and would form a lesser angle (angle number one 31) with the dispenser bottle centre line (15) whereas funnel two/floater landing site (7) would be shorter in length and would form a greater angle, (angle number two 32) with the centre line (15) of the dispenser bottle (1).
  • the dispenser bottle (1) wall sloping inward would stop and run parallel to each other, forming a cylindrical shape again.
  • a rubber lid (9) would be fixed to seal the dispenser bottle and its contents from the outside environment.
  • the centre of the rubber lid (9) would be marked by an indentation as depicted by rubber lid centre (28) in Fig 3 and rubber lid centre (28) would be used to fix the drip set connector (25).
  • the drip set connector (25) should be only fixed to rubber lid centre (28) which would be in the centre of the rubber lid (9).
  • the dispenser bottle (1) will be able to carry one pint or any volume required and the size of the bottle could be minimised or maximised according to the volume it needs to carry.
  • the dispenser bottle (1) disclosed above may be made of plastic or any other material that can be and is being used for the manufacture of saline bottles, the manufacturing process could be by moulding or and other manufacturing processes known by those who have a skill of the art.
  • the floater inside the dispenser bottle would have a unique shape to be compatible with the dispenser bottle (1) lower end and the drip set connector (25) in order to facilitate a dispenser bottle free from air leakage.
  • the floater (3) will consist of two shapes, as seen in Fig 2.
  • the top end would consist of a trapezoid shaped structure called a floater trapezoid structure plus the floater arms (16) while the lower end would consist of a cylindrical structure called a floater cylinder (17). Harmonisation of both these structures would give birth to the floater (3).
  • the diameter of the floater trapezoid structure plus the floater arms (16) would be marked as (29). This length and the inner diameter of bend two (11) also marked as (29), would be equal in length as shown in Figs 4.
  • the floater trapezoid structure plus the floater arms (16) would have a sealed air trapped compartment in the middle called the floater air trapped compartment as shown in (18).
  • the idea of having an air trapped compartment (18) in the centre of (16) is to make the floater (3) float when the dispenser bottle (1) is filled with a fluid. This would enable the floater (3) to move with the fluid inside the dispenser bottle (1), when the fluid level runs down. (16) would have two floater arms (22) built into it and would land on top of the funnel two/floater landing site (7) of the dispenser bottle (1).
  • Floater cylinder (17) too would have a hollow compartment inside forming the floater cylinder hollow compartment (19).
  • (19) is to accommodate the drip set connector (25) as the floater comes down and lands on the rubber lid (9).
  • At the end of the floater cylinder (17) would be a rubber ring (20) going around the circumference of the lower end of the floater cylinder (17), as shown by figs 2 and figs 3.
  • the rubber ring (20) would be fixed to the floater cylinder (17) as shown in figs 2.
  • the circumference of the rubber ring (20) should be the same as the circumference of (17), and the rubber ring (20) would fix to (17) by enabling (17) to sink into (20), by fitting into the rubber ring grove (23).
  • the height of (17) should be ⁇ 75 and > 50% of the height of (8) as shown in Figs 3.
  • the floater cylinder (17) would be made heavier than the floater trapezoid structure plus the floater arms (16) in order to prevent the floater from turning around while floating and to help the floater (3) to move only in the downward direction by keeping the lower end heavy. This could be achieved by making the rubber ring (20) heavy or the structure of (17) heavy.
  • Floater (3) stability would be achieved by the floater arms (22), preventing the floater (3) from turning while floating.
  • the collective height of (7) and (8) marked as (30) in figs 4 of the dispenser bottle (1) should be equal to the collective height of (16) and (17) of the floater (3), also marked as (30) in Figs 4.
  • the structure of the floater (3) would be made to fit the lower end of the dispenser bottle (1), funnel two (7) and cylinder two (8) to perfection in order to achieve the air leakage free dispenser bottle (1) as depicted by figs 1 and figs 3.
  • the floater (3) disclosed above may be made of plastic or any other material that can be and is being used for the manufacture of saline bottles, the manufacturing process could be by moulding or and other manufacturing processes known by those who have a skill of the art.
  • funnel two/floater landing site (7) would be ⁇ 75% and >50% of the size of the floater arms (22), and (22) would come and land on top of (7) (once the fluid runs out therefore funnel two (7) could also be called as the floater landing site).
  • angle number four The angle made by the floater trapezoid structure plus the floater arms (16) with the floater cylinder (17) at the connecting site would be called angle number four (21) as shown in Fig 3. Angle number three (24) would be equal to angle number four (21).
  • the height of the floater cylinder (17) would be ⁇ 75% and >50% of the height of the dispenser bottle (1) cylinder two (8).
  • the diameter of the floater cylinder (17) would be ⁇ 75 and >50 than the diameter of the cylinder two (8).
  • the floater cylinder hollow compartment (19) would accommodate the drip set connector (25) into its hollow compartment.
  • the rubber lid (9) used in all other saline bottles will seal the dispenser bottle and its contents from the outside environment.
  • the drip set would fix to the dispenser bottle (1) via the drip set connecting rod (25), and drip set connector (25) would fix to the rubber lid (9) at its centre (28) in order to facilitate the invention by not allowing drip set connector (25) to be connected elsewhere other than the centre of rubber lid (9) marked as rubber lid centre (28) with an indentation on the surface of the rubber lid (9). This would guarantee that the floater (3) landing on the rubber lid (9) would not be disturbed by the drip set connector (25).
  • funnel one (6) will be to guide the floater (3) into the lower end of the dispenser bottle (1) toward funnel two (7) and cylinder two (8) as shown in drawing Figs (1) and Figs 3.
  • the floater (3) will be able to float in the fluid at the same level or in a slightly elevated level inside the dispenser bottle (1) Figs 1, with the aid of floater air trapped compartment (18) inside floater trapezoid structure plus the floater arms (16), and when the dispenser bottle (1) is connected to the patient via the drip set (13), by hanging the dispenser bottle (1) to a saline stand with the aid of the hanger (14) (the drip set will be connected to the lower end of the dispenser bottle (1) across the rubber lid (9) to its rubber lid centre (28) by the aid of (25).
  • the level of the fluid level inside the dispenser bottle (1) will decrease due to the infusion of the fluid via the drip set (13) into the patient's circulatory system and the floater (3) too would move down with the level of the fluid, as shown by the arrows in Fig 1 with an arrow.
  • funnel one (6) of the dispenser bottle (1) When the fluid reaches funnel one (6) of the dispenser bottle (1), funnel one (6) will guide the floater (3) towards funnel two (7) and cylinder two (8) of the dispenser bottle (1), as shown by Figs 1 and Figs 3. Once the fluid runs out of the dispenser bottle (1) the floater (3) will connect tightly to the appropriate sites of the dispenser bottle's (1) lower end as described below,
  • the rubber ring (20) When the fluid runs out of the dispenser bottle (1), the rubber ring (20) would come and land on top of the rubber lid (9) covering the drip set connector (25) forming the "Second Air Barrier" with the aid of the floater cylindrical hollow compartment (19), and thereby drip set connector (25) would be sealed from the bottom by the runner ring (20) and the rubber lid (9), and from all other sides by floater cylinder hollow compartment (19), therefore no air would be able to come inside floater cylinder hollow compartment (19) thus preventing air from reaching the drip set connector (25) and preventing air flow into the drip set (13) and flowing into the patient's circulation.
  • the dispenser bottle (1) and the floater (3) will be made of material which will be able to withstand the sterilisation/disinfection methods in existence today. (Same materials that make the present day saline bottles plus syringes can be utilised)
  • substance in fluid form (normal saline, antibiotics, etc) need to be given to patients by using a drip set which will be attached to a bottle.
  • the bottle will act as the reservoir for the fluid while the drip set would deliver the fluid to the patient.
  • the air should be removed and then only can a new bottle be attached thereby consuming time and resulting in overloading the staff with unnecessary work.
  • This new inventive mechanism can help to save time and reduce the workload of the staff by preventing them from constantly checking the intravenous fluid levels and would give reassurance to patients on intravenous lines that air passing into their circulation is not a possibility.

Abstract

La présente invention concerne un flacon distributeur pour fluides (1). Sa forme unique comprend deux structures en entonnoirs (6, 7) et des extrémités, l'extrémité inférieure (8) étant cylindrique. Ce flacon comporte également un dispositif de flotteur (3) en deux parties. La partie supérieure du flotteur (16) est une structure trapézoïdale comportant en son centre un compartiment (18) piège à air. La partie inférieure est un cylindre creux (17) dont le pourtour d'extrémité est entouré d'une bague de caoutchouc (20). Ce flacon distributeur est relié au patient par l'intermédiaire d'un dispositif de goutte-à-goutte (13). La forme unique du flacon distributeur et la forme unique du flotteur contenu dans le flacon distributeur empêcheront que l'air accumulé à l'intérieur du flacon distributeur ne pénètre dans la circulation sanguine du patient dès qu'il n'y a plus de fluide dans le flacon distributeur.
