Description

A LID STRUCTURE FOR USE IN SUCTION BAGS

Technical Field

The invention relates to a disposable suction bag and lid comprising a bag and lid for collecting patient fluids and secretions during the performance of medical procedures.

Known State of the Art

The structure that enables the suction process consists of a disposable bag, a lid and an outer chamber. It contains an outer chamber called a canister that protects the bag from the outside. Suction bags and their components and the chamber to which they are attached are used in operating rooms, intensive care wards, patient rooms, clinics and offices, and in places where aspiration is performed on patients receiving special treatment at home.

In the current technique, it is first used by collecting directly into multi-use glass or plastic jars. Then plastic disposable bags were made. Vacuum inlets were configured on the lid and multi-use jar.

There are some technical problems with the disposable bags and lids that enable aspiration. These problems include;

• losses in vacuum due to the use of valves configured on the canister,

• presence of a valve connection that is not user-friendly and also causes visual pollution,

• contaminated environment caused by the outer chamber connection units of the valve,

• not user-friendly because the lid design is too perforated,

• lack of emphasis on VFE (Viral Filtration Efficiency) tests in existing filter productions at the vacuum connection port,

• failure to consider patient safety by leaving the patient use port empty,

In the patent literature review on suction systems, some applications were found. Among these applications, in the application numbered W0202020201621A1 ; The invention relates to a suction bag for surgical and medical use. The suction bag has a connection for suction. The suction bag consists of a bag portion and a lid. The lid consists of a negative pressure duct that allows the suction bag to be vacuumed with negative pressure, a mounting cavity for the filter surrounded by a sleeve, and a filter installed in the mounting cavity connected to the negative pressure duct. The crosssection of the sleeve differs from the circular form in that the widest point of the outer diameter (d1 ) is 0.90% wider than the narrowest point (d2).

In the application numbered WO2019162572A1 ; the invention relates to a suction bag for surgical and medical use. The suction bag has a flexible closed bag portion. The flexible closed bag portion has a width direction (W) and a length direction (L). The flexible closed bag portion has an upper part and a lower part in the length direction (L). The lower part of the bag is folded into the upper part. In this way, the entire volume of the lower part is turned upside down in the upper part and the suction bag fits neatly into the canister.

Description of the Invention

The objective of the invention is to provide a different and new product that brings a new opening in this field, unlike the elements that make up the suction system components used in the current technique.

An objective of the invention is to provide easy opening and tight closure of the lid by creating high resistance to the lid with little force thanks to the retaining surface protrusions formed on the lid, unlike the lids used in the current technique. It also provides a high strength effect to the lid.

Another objective of the invention is to mount the vacuum control valve directly on the lid thanks to the port slot formed on the lid. Thus, in hospitals that do not have an adjustable vacuum manometer on the wall, it is possible to control the vacuum through the suction bag.

Relevant to the above objective; by integrating the vacuum control valve on the lid, an ergonomic and affordable solution is offered to the user by adjusting on/off. Likewise, it contributes to hospital vacuum efficiency in terms of affordable cost and practical use. Another objective of the invention is to provide a hydrophobic filter that is tightly and sturdily attached to another port slot formed on the lid, and virus efficiency tests of the filter have been completed.

Relevant to the above objective; it has a protective lid integration so that the hydrophobic filter does not fall out of the slot where it is positioned and does not come out.

Another objective of the invention is to integrate anti-reflux silicone into another slot formed on the lid. It is made of anti-reflux silicone material and has a flexible structure. With its unidirectional moving "C" form, it acts as a check valve by creating force against the flow direction.

Another objective of the invention is that the so-called canister, which protects the bag, which is integrated into the lid with a shrink fit, from external factors, contains a monolithic fixing element. Thanks to the holder produced in a monolithic structure with the main chamber, it is possible to produce production easily and in one go.

Detailed Description of the Invention

Figures 1 and 2 illustrate a suction structure (100) for collecting patient fluids and secretions during the performance of medical procedures, comprising a main chamber (110), a lid (120) covering said main chamber (110), a filter slot (121 ) formed on said lid (120) and an anti-reflux slot (122) (see figure-3). A handle (123) having multiple pressure surfaces (124) is configured on said lid (120) (see figure-6). The handle (123) provides a high degree of strength to the lid (120), as well as a high tightening resistance with little force, and allows the lid (120) to be opened by simply turning the lid (120). A valve connection port (125) is also formed on the said lid (120) and a check valve (150) is attached to this valve connection port (125). With the integration of the vacuum check valve (150) on the lid (120), the user is provided with convenience by adjusting on/off. Likewise, since some hospitals do not have a check valve, it contributes to hospital vacuum efficiency in terms of affordable cost and practical use.

In addition, the anti-reflux silicone (140) with anti-reflux lid (141) positioned in the antireflux slot (122) is integrated into the system. It is made of silicone material and is flexible. It acts as a check valve by creating force against the flow direction with its unidirectional moving "C" form. The blood/liquid from the patient is filled into the bag through the patient port inlet and the air is drawn through the vacuum port outlet while the blood/liquid is trapped in the main chamber (110) until the hydrophobic filter (130) is activated. If the flow is interrupted, the anti-reflux silicone (140) placed in the patient port prevents the spillage of the trapped blood/liquid by acting as a check valve.

On the other hand, a high density hydrophobic filter (130) and filter holder (131 ) are positioned in the filter slot (121 ). Hydrophobic filter (130) is made of PE material. It has a porous structure. Thanks to its hydrophobic feature, it cuts the air and liquid flow in the system in contact with the liquid. Likewise, when the liquid filled in the bag comes into contact with the filter positioned at the vacuum outlet of the lid, it acts as a check valve thanks to its hydrophobic feature and ensures that the air and liquid flow in the system is stopped. In addition, VFE (Viral Filtration Efficiency and BFE (Bacteria Filtr. Eff.) tests are available. The main difference from the filters in the current technique Virus efficiency tests have been completed. With maximum safety in mind, the addition of a protective filter holder (131 ) has been integrated so that the filter cannot fall or come out of its place I slot in any way.

In Figure-6.3, the fixing duct (151 ) that allows the check valve (150) to be fixed to the valve connection port (125) and the passageway (152) that allows the liquid to pass through are illustrated. The supporting surface (153) for the adjustment button (154) to stand and rest at the desired distance is formed on the inside. In hospitals that do not have an adjustable vacuum manometer on the wall, it provides the ability to control the vacuum over the suction bag. It offers an ergonomic and affordable solution to the user by adjusting on/off.

In Figure-5; the general perspective view of the main chamber (110) with the holder (111) formed in a monolithic structure is illustrated. The main chamber (110) contains the holder (111) formed in a monolithic structure on the main chamber (110) and the fitting arms (112) that enable the said holder (111 ) to be attached with the fitting technique with a single move and the fitting extension (113) extending from the narrow structure. By means of the holder (111 ), which is produced in one time and in one operation during the molding stage, an economical structure that is easy to use is put forward.

The inner surface (127) of said lid (120) is formed with strength-enhancing ribs (126) formed on the inner surface (127) of said lid (120) and covering all port slots, and includes a handle (123) having a high extension from the outer surface (128) of said lid (120).
