Description

{Sap filter device for easy dispersion of sap}

The present invention relates to a sap filter device that facilitates sap dispersion, and more specifically, to a sap filter device that facilitates sap dispersion, in which sap can be filtered at a stable and uniform pressure over the entire area of the filter, the filtered sap can be stably discharged, and the sealing structure of the main body is improved to prevent fluid leakage.

Typically, medical high-pressure IV lines are equipped with a filter device to filter out foreign substances contained in the IV.

These high-pressure liquid line filter devices are commonly referred to as male lure lock filters and have a membrane filter built into them.

Membrane filters have the disadvantage that they cannot withstand the pressure when sap is sprayed at high pressure and can be damaged or broken, making it impossible to properly perform the filtration function, which can lead to foreign substances in the sap entering the human body.

As a solution to the problem of breakage of such membrane filters, a ‘high-pressure liquid line male luer lock filter structure’ is proposed in Korean Patent Publication No. 10-1824065.

Meanwhile, the conventional technology is provided with upper and lower bodies forming the body of the filter device, and an inlet and outlet are formed in each of the upper and lower bodies.

However, in the prior art, the upper and lower bodies of the filter device were formed with male and female joints in their respective openings to be mutually connected and have a sealing force, but there was a problem in that leakage occurred at the connection part of the upper and lower bodies.

There was also a problem where the filter became defective due to the connection part with the body being ruptured by the pressure of the sap.

The present invention has been made to solve the problems of the prior art, and the purpose of the present invention is to provide a sap filter device that facilitates sap dispersion, in which sap can be filtered at a stable and uniform pressure over the entire area of the filter, the filtered sap can be stably discharged, and the sealing structure of the main body is improved to prevent fluid leakage.

The above-described object of the present invention can be achieved by a sap filter device that facilitates sap dispersion, comprising: a body through which sap flows out after flowing in, and which is composed of a body and a cover; a filter member inserted into the body to filter the sap; a joining member that joins the body and the cover to seal it; wherein the body has a first port formed on one side through which sap flows in, a second port formed on the other side through which sap flows out, a receiving space formed inside into which a filter is inserted, an opening formed on the front, an annular support rib formed on the outer periphery of a bottom surface, a plurality of channel protrusions and channel grooves formed in a longitudinal direction on the bottom surface, and a receiving space formed inside into which a filter member is inserted; and a cover that is sealedly joined to the opening of the body, and has a recessed portion formed inside corresponding to the receiving space to receive the filter member.

According to the present invention, the sap can be filtered at a stable and uniform pressure over the entire area of the filter, the filtered sap can be stably discharged, the sealing structure of the main body is improved to prevent leakage of the fluid, so that the sap is uniformly distributed, the filtration performance can be increased, and the filter damage can be prevented, so that the product life can be stably maintained for a long time.

The following is a detailed description of a preferred embodiment based on the attached drawings.

The embodiments described below are intended to describe in detail enough to enable a person skilled in the art to easily carry out the invention, and do not mean that the technical idea and scope of the present invention are limited thereby.

As shown in FIGS. 1 to 4, the sap filter device according to the present invention, which facilitates sap dispersion, comprises: a body (B) composed of a body (100) and a cover (200), through which sap flows in and out; a filter member (300) inserted into the body (B) to filter sap; and a joining part that joins the body (100) and the cover (200) to seal them.

The above body (B) is configured to include a body (100) in which a first port (111) for introducing sap is formed on one side, a second port (112) for introducing sap is formed on the other side, a receiving space (120) for inserting a filter (320) is formed inside, an opening is formed on the front, an annular support (130) is formed on the outer periphery of the bottom surface, a plurality of channel protrusions (142) and channel grooves (144) are formed to protrude in the longitudinal direction on the bottom surface, and a receiving space (120) for inserting a filter member (300) is formed inside; a cover (200) which is sealedly connected to the opening of the body (100) and has an indentation (220) formed inside corresponding to the receiving space (120) to receive the filter member (300).

A plurality of protrusions (142) are formed on the bottom surface of the receiving space (120) of the body (100), and a plurality of grooves (144) are formed between the protrusions (142).

In addition, the body (100) is connected to the first port (111) and the second port (112), respectively, and a first hole (121) and a second hole (122) are formed on both sides of the bottom surface.

Therefore, the sap can flow in from the bottom through the first hole (121), spread out widely between the filter (320) and the euro groove (144), and flow out through the second hole (122).

The above-mentioned joint is formed by including a protruding step (420) that is formed protrudingly on the outer periphery of the opening of the body (100); an insertion groove (442) that is inserted into the outer periphery of the cover (200) and into which the protruding step (420) is inserted; and an annular protruding part (440) that is formed protrudingly on the lower surface of the cover (200) and is inserted so as to be in close contact with the inner periphery of the opening of the body (100) and is joined so as to be in close contact with the lower surface of the body (100).

Therefore, when the cover (200) is joined to the body (100), the annular protrusion (440) of the cover (200) is forcibly fitted into the inner surface of the protruding step (420) of the body (100) to ensure airtightness.

Meanwhile, a triangular protrusion (441) that is sharply formed and melted by high frequency is provided at the top of the protruding step (420).

In response to this, a triangular groove (443) is formed on the bottom surface of the receiving space (120) of the body (100) so that the triangular protrusion (441) can be inserted.

Therefore, after the cover (200) is bonded to the body (100), high-frequency bonding is performed on the bonding portion, so that the triangular protrusion (441) melts and the molten material fills the gap, thereby realizing a strong bonding force and sealing state between the cover (200) and the body (100).

Meanwhile, a retaining portion (500) is formed at the contact area between the annular protrusion (440) of the cover (200) and the bottom surface of the body (100) to pressurize and fix the outer periphery of the filter member (300).

The retaining portion (500) is formed by including a retaining projection (520) that is formed to protrude in a circumferential direction on the lower surface of the annular protrusion (440) of the cover (200) and is fitted into the retaining groove (540); and a retaining groove (540) that is formed to recess in a circumferential direction on the upper surface of the lower surface of the body (100).

Accordingly, the outer periphery of the filter (320) of the filter member (300) can be firmly joined by being sandwiched between the retaining projection (520) and the retaining groove (540), and the risk of the filter (320) being crumpled and deformed can be prevented in advance.

Meanwhile, referring to FIG. 2, the body (100) is formed with a chamber (160) that is connected to the first hole (121) to store a certain amount of fluid, and the cover (200) includes a chamber cover part (260) that is sealedly connected to the chamber (160).

Accordingly, since the sap introduced through the first hole (121) of the body (100) can be stored in a certain amount in the chamber (160) and then supplied to the receiving space (120) of the body (100), a shock-absorbing function can be implemented to prevent the sap from colliding abruptly with the filter (320).

Meanwhile, the filter member (300) is composed of a thin film filter (320) and a filter mesh body (340) that supports and fixes the filter (320).

The filter (320) is made of TPU (Thermoplastic Poly Urethane) nanofibers.

Referring to the enlarged photo of Fig. 5, the nanofibers have an average diameter of 0.7 ㎛ and a basis weight of 1 to 5 g/㎡.

The filter (320) formed using the above nanofibers has an air permeability of 300 to 500ℓ/㎡, an average pore size of 3 to 5㎛, and an average permeation amount of 30 to 35g/㎡.

If the air permeability is less than 300, the standard performance is inadequate, and if it is more than 500ℓ/㎡, it is excessive and there is a risk of reduced filtering performance.

If the average pore size is less than 3, the standard performance will be insufficient, and if it is more than 5㎛, it may be excessive and the filtering performance may deteriorate.

If the weight is less than 1, the standard performance will be insufficient, and if it is more than 5 g/㎡, it is excessive and there is a risk of reduced filtering performance.

Referring to FIGS. 6 and 7, it can be seen that the filter (320) of the present invention has a higher porosity and thus superior air permeability than a filter made of conventional acrylic polymer material when the average pore size is 3 to 5 μm.

Although the invention has been described with reference to preferred embodiments thereof, it will be readily apparent to those skilled in the art that various modifications and variations may be made therein without departing from the spirit and scope of the invention, and it is to be understood that all such modifications and variations are intended to fall within the scope of the appended claims.
