[0002] A MEDICAL FLUID FLOW ADJUSTER

[0003] Field of the Invention

[0004] The present invention relates to blood, serum or fluid flow adjustment in the medical sector.

[0005] In particular, the present invention relates to a two-part flow rate adjuster for adjusting the amount and speed of flow in the hose by mounting it on the flow line of hoses used for blood, serum or fluid nutrition in the medical sector.

[0006] State of the Art

[0007] Nowadays, the drip adjustment set, which adjusts the amount of fluid passing through the hoses in the delivery of serum, blood or other fluid nutrients used in the medical sector, has been used for a long time. The amount of fluid passing through the hose can be adjusted precisely, drip adjustment sets used today differ in terms of production features and working principles.

[0008] One of the undesirable features of the products of the state of the art is that they have a rather complex production method. Since these products have a short lifespan and high turnover, it is crucial to manufacture them using a simpler and more efficient production process. On the other hand, another important feature is that it has a design that allows the user to make precise adjustments during use. In addition, the fact that the adjustment set can be easily changed by the patient / caregiver / child and that this can be noticed late by the staff is a major problem for the safety of these products.

[0009] Again, in the stat of the art, there are the disadvantages mentioned above in the patent document called “adjusting valve" numbered EP1415675. Since it consists of many parts, it also brings risks during assembly.

[0010] Again, in the state of the art, in the patent numbered JPS61247470, there was a need to use an additional seal ring for sealing. This increases both the cost and the time spent on assembly. Sealing rings deform over time, making the product unusable. Again, in the state of the art, PCT application numbered WO2019117835A2 discloses “a fluid flow regulator comprising a fluid inlet line, a fluid outlet line, a fluid passage part having a cylindrical body with one end open and the other end closed, positioned between said lines, a fluid flow adjuster having a flow rate male cylinder which enables the user to intervene in the velocity of the fluid by contact, a flow rate adjustment part which can be mounted on the fluid passage part with the transition of the flow rate male cylinder to the cylindrical body”.

[0011] Object of the Invention

[0012] In order to eliminate the disadvantages of the known state of the art, an object of the present invention is to provide a more economical, less risky production process by forming said fluid flow adjuster from only two parts without an additional sealing ring.

[0013] Another object of the present invention is to provide a fluid flow adjuster, which is a drip adjustment set suitable for production in a single operation.

[0014] Another object of the present invention is to minimize the risk of fluid leaking out of the mechanism in the fluid flow adjuster.

[0015] Another object of the present invention is to facilitate the user's precise adjustment of the fluid flow adjuster.

[0026] Detailed Description of the Invention

[0027] The present invention is a two-part flow rate adjuster for adjusting the amount and speed of flow in the hose by mounting it on the flow line of hoses used for blood, serum or fluid nutrition in the medical sector.

[0028] Figure 1 shows the perspective view of the assembly of the invention. According to the figure, a flow rate adjuster with two parts, the upper part (1 ) and the lower part (2), can be seen. Figure 2 shows the sectional view of the assembly of the invention. According to the figure, an inlet port (4) for the hose is formed on the inside of the upper part (1 ). The hose through which the fluid flow occurs does not pass outside the inlet port (4), but is mounted by entering the same.

[0029] As can be seen in Figure 2, a seal (2) is positioned between the lower part (3) and the upper part (1 ) for sealing purposes. The seal (2) and lower part (3) are integrated through an overmolding process, forming a monolithic combined part (B). (Figure -13) In this way, the seal (2), which is an external element, is combined with the lower part (3), reducing the number of elements and thus providing advantages in assembly and use.

[0030] As can also be seen in Figure 2, a lower part inlet port (5) is formed inside said lower part (3) for fluid passage. Said lower part inlet port (5) is positioned symmetrically with the upper part inlet port (4) formed in the upper part (1 ) (Figure 5). The hose through which the fluid flow occurs does not pass outside the lower part inlet port (5), but is mounted by entering the same. In this way, the fluid flowing from the hose enters and exits the flow rate adjuster of the invention through these ports (4, 5). Again in Figure 2, for the tight assembly of the upper part (1 ) and the lower part (3), a lower part locking tab (9) is formed at the top of the lower part (3) and an upper part locking tab (10) is formed at the end of the upper part (1 ).

[0031] Figure 3 shows the fluid flow path (11 ) view in the invention. In order to adjust the fluid flow in the flow rate adjuster of the invention, a flow path (11 ) is formed between the upper part inlet port (4) and the lower part inlet port (5). Figure 4 shows the drip adjustment channel (7) view of the invention. According to the figure, an adjustment channel (7) is formed in the flow path (11 ) to adjust the fluid flow. The fluid flowing between the upper part inlet port (4) and the lower part inlet port (5) passes through a transition channel (6) and the said adjustment channel (7) in the flow path (11 ), and the flow rate is adjusted. An adjustment step (8) has also been created for this adjustment process. As can be seen in the side assembly view of the invention in Figure 6, adjustment step (8) marks are created on the flow rate adjuster that is the subject of the invention. The fluid flow rate can be easily adjusted by rotating the fluid flow rate adjuster of the invention. Figure 7 shows the detail view of the drip adjustment channel (7) of the invention. According to the figure, the flow rate of the fluid from the transition channel (6) to the adjustment channel (7) is adjusted by rotating the flow adjuster, here in the form of the adjustment channel (7). Alternative forms of said adjustment channel (7) are also seen in Figure 7. Said form can be in different geometric shapes such as angular, oval, straight, helical, curved, etc. It can also be manufactured in different widths and depths. This form may vary depending on the purpose of use and preference.

[0032] Figure 8 shows the upper part (1 ) view of the invention. It preferably has a cylindrical structure and the concave upper part comprises a rotation holding cavity (13). Again, an upper part inlet port (4) is formed on the upper part (1 ) for liquid entry. The tubing is mounted in such a way that the upper part enters into the inlet port (4). Figure 9 shows the A-A section view of the upper part (1 ) of the invention. The upper part inlet port (4) formed on the inside of said upper part (1 ) can be seen in Figure 9. Figure 10 shows the bottom view of the upper part (1 ) of the invention. Figure 10 shows the adjustment channel (7) and transition channel (6) and the adjustment step (8).

[0033] Figure 11 shows the top view of the lower part (3) of the invention. It preferably has a cylindrical structure and the concave lower part comprises a rotation holding cavity (12). Again, a lower part inlet port (5) is formed on the lower part (3) for liquid entry. The tubing is mounted so that it enters the port (5). Figure 12 shows a section view of the lower part (3) of the invention and Figure 13 shows the A-A detailed section view. The lower part inlet port (5) formed inside said lower part (3) can be seen in Figure 13.

[0034] The upper part (1 ) and lower part (3) of the flow adjuster of the invention can be manufactured optionally. Likewise, the sealing seal (2) can be manufactured from PC- ABS, ABS, PC and its derivatives.
