Description

Tube apparatus

The present invention relates to a tube device, and more particularly, to a tube device capable of preventing contamination by bacteria or microorganisms.

Depending on the patient, such as Ringer's solution, analgesic, or anticancer drug, a device capable of automatically injecting may be used for administration of a human infusion that needs to be continuously administered in a small amount for a period of time.

The apparatus capable of automatically injecting a human body injection may be of two types, commonly referred to as a syringe pump and an infusion pump.

In general, a syringe pump is a device that mechanically presses the plunger of a syringe by mounting a syringe filled with a human injection, and can continuously inject a human injection of one syringe for a predetermined time, and replace the syringe if necessary. Additional injections are possible.

This may not be suitable for patients who need to continuously administer large amounts of human infusion since the syringe volume is relatively small and the administration of the human infusion is discontinued during syringe replacement.

In addition, it had to be fixedly mounted in a place close to the patient, which was very inconvenient for patients who could move.

On the other hand, a conventional infusion pump can continuously administer a human infusion supplied from a bag or a bottle in which the human infusion is stored, and thus is suitable for administration of a large amount of the human infusion over a long period of time. Can provide convenience.

On the other hand, there is a concern that human body injections, such as Ringer's solution or analgesic or anticancer drugs, which are injected into the human body or animals and plants, may be contaminated by bacteria or microorganisms during the manufacturing process, storage process, injection process, or dispensing process.

Various contaminated accidents occurring in the medical field by such contaminated human infusions cause fatal loss of life, and are frequently injected into elderly people or by multiple human infusions, resulting in fatal medical accidents. .

The present invention is to provide a tube device that can prevent a medical accident in advance by enabling real-time or periodic discrimination of contamination by bacteria or microorganisms before the injection of a human body into a human body or a living body. However, these problems are exemplary, and the scope of the present invention is not limited thereby.

The tube device according to the spirit of the present invention for solving the above problems is installed on a body, a pump part that is installed on the body, and forms a pressure difference inside the tube device so as to transport a human body injection, and the body , A tube device that can be applied to a human body infusion transport device, comprising a body infusion contamination detection unit capable of detecting contamination by bacteria or microorganisms in a non-contact manner by using the optical properties of the human body infusion, wherein the pump unit A non-optical unit which is a flexible material so as to correspond with; An optical unit which is a light-transmitting material to correspond to the human body injection contamination detection unit; And a valve that is connected to the non-optical unit on one side, the optical unit on the other side, and can block the flow of the human body injection material.

In addition, according to the present invention, the valve comprises: a first valve formed at the front end of the optical unit; And a second valve formed at a rear end of the optical unit.

According to an embodiment of the present invention made as described above, prior to the injection of the human body or animals and plants into the human body, it is possible to discriminate the contamination by bacteria or microorganisms in real time or periodically to prevent medical accidents in advance. It has the effect of preventing it. Of course, the scope of the present invention is not limited by these effects.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and the following embodiments make the disclosure of the present invention complete, and the scope of the invention to those skilled in the art It is provided to inform you completely. In addition, for convenience of description, in the drawings, the size of components may be exaggerated or reduced.

1 is a conceptual diagram illustrating a human body injection device 100 according to some embodiments of the present invention.

First, as shown in FIG. 1, the human body injection device 100 according to some embodiments of the present invention includes a body 10, a pump unit 20, and a human body injection contamination detection unit 30 ).

Here, for example, the body 10 is formed with a receiving space therein to accommodate the pump portion 20 and the human body injection contamination detection unit 30, sufficient strength and durability to support them It may be a structure having a.

In addition, for example, the pump unit 20 is installed in the receiving space of the body 10, the human body injection material (1) that can be injected into the human body or animals and plants, such as Ringer's solution or painkillers or anticancer drugs B, it may be a kind of pressure forming device that forms a pressure difference inside the tube device 40 so as to be transported in the biological direction.

Here, although not shown, the pump unit 20 is a syringe pump that can be applied to a conventional syringe pump (syringe pump) or infusion pump (infusion pump), a rotating device or a piezoelectric element, all of a variety of pumping devices Can be applied.

In addition, for example, the human body injection contamination detection unit 30 is installed in the receiving space of the body 10, and uses the optical properties of the human body injection 1 to prevent contamination by bacteria or microorganisms. It may include a kind of biosensor that can be detected in a non-contact manner.

More specifically, for example, the human body injection contamination detector 30 may irradiate the laser beam L to the human body injection 1 and detect a speckle pattern generated by multi-scattering the same. As a non-contact speckle sensor, the principle of a chaotic wave sensor can be applied.

For example, when explaining the principle of the chaotic wave sensor, in the case of a material having a homogeneous internal refractive index such as glass, refraction occurs in a certain direction when irradiated with interference light.

However, when a coherent light, such as a laser, is irradiated to an object having an inhomogeneous refractive index or a fine refraction or scattering projection, very complex multiple scattering occurs within the material.

Part of the light scattered through the complex path through the multiple scattering passes through the human injection, which is an object to be inspected. The light passing through various points of the inspection object causes constructive interference or destructive interference with each other, and the constructive/destructive interference of these lights generates a grain-like pattern (speckle). .

Light scattered through such a complex path may be referred to as a “chaotic wave,” and the chaotic wave may be detected through an interference light speckle, and the interference light speckle may be a laser speckle when the interference light is a laser. This can be detected.

If the stable medium is irradiated with the interfering light, the stable speckle pattern without change can be observed when the stable medium without the movement of the internal constituent materials is irradiated with the interfering light (for example, laser).

However, when the inside contains an unstable medium with movement among the internal constituent materials such as bacteria, the speckle pattern changes.

In other words, due to the microbial microbial activity (eg, intracellular movement, microbial movement, etc.), the optical path may change minutely over time. Since the speckle pattern is a phenomenon that occurs due to interference of light, a minute change in the optical path may cause a change in the speckle pattern. Accordingly, by measuring the temporal change of the speckle pattern, it is possible to quickly measure the microbial life activity. As described above, when measuring the change over time of the speckle pattern, the presence and concentration of microorganisms can be known, and furthermore, the type of microorganism can also be known.

The inspection object described in the present specification is the human body implant 1 inside the tube device 40, and a configuration for measuring a change in the speckle pattern with time of the human body implant is defined as a chaotic wave sensor. can do.

The chaotic wave sensor of the present invention may be configured in various forms such as a reflective type and a transmissive type, and the optical system may be configured in a packaging type.

In addition, the human body injection contamination detection unit 30 may use a laser light L having good coherence as a light source. However, in addition to the laser light source, a light source having improved coherence may be used by including a filter that passes only a specific wavelength or a specific wavelength in general illumination. Alternatively, it may be measured by using a wavelength (for example, infrared rays, ultraviolet rays, etc.) of an area outside the visible light band.

In addition, the human body injection contamination detection unit 30 may use a camera that is a photographing device for photographing an image. When interfering light is irradiated to the human implant, an interfering light speckle may be formed by multiple scattering. If viruses, bacteria, microorganisms, etc. are present in the human injection, it is possible to quickly determine the presence and concentration of bacteria and microorganisms in the object under test based on the pattern of the interfering light speckle that changes over time.

For example, as the interfering light is irradiated to the object to be inspected at regular intervals at a reference time, an interfering light speckle may be formed in the object to be inspected, and as the object to be inspected in which multiple scattering occurs using a camera or the like is photographed , An interference light speckle image in which an interference light speckle is formed may be generated. At this time, it can be used as a camera including a two-dimensional image sensor or a one-dimensional optical sensor to measure the speckle pattern of the generated plurality of images. For example, a camera equipped with an imaging element such as a CCD can be used as the measurement unit.

Therefore, in the photographed interference light speckle images, it is possible to determine whether or not bacteria and microorganisms are present in the human injection by a non-contact method by confirming whether the pattern of the interference light speckle changes with time. . For example, if there is no movement in the human body implant, the interference light speckle does not change the interference pattern with time. That is, in the absence of the movement, in the interference light speckle images measured for each reference time, the pattern of the interference light speckle may have a constant interference pattern. As described above, when the interference light speckle images have little or no change in the interference pattern over time, the control unit to be described later may determine that bacteria and microorganisms are not present in the human injection.

On the other hand, when the pattern of the interference light speckle changes, the controller may determine that bacteria and microorganisms are present in the human injection. That is, when bacteria or microorganisms are present in the human injection, over time, the bacteria and microorganisms multiply and the bacteria and microorganisms may continuously move. Due to these movements of bacteria and microorganisms, the pattern of the laser speckle can be continuously changed over time. Accordingly, in the interference light speckle image measured for each reference time, when the pattern of the interference light speckle is changed beyond the determined error range, the controller may determine that bacteria and microorganisms are present in the human injection.

At this time, the degree of change in the pattern of the interference light speckle may be determined according to the concentration of bacteria and microorganisms. Accordingly, the concentration of bacteria and microorganisms can be measured through time correlation analysis. For example, a standard deviation of the light intensity of the interference light speckle may be used to measure the degree of change in the pattern of the interference light speckle.

FIG. 2 is an exploded perspective view showing a human body injection device 200 and a tube device 40 according to some other embodiments of the present invention, and FIG. 3 is a human body injection device 200 and a tube of FIG. 2. It is a sectional view of the assembly of the device 40.

Here, as the spectral bandwidth of the light source for determining the coherence of the laser light L of the laser source part 31 is short, measurement accuracy may increase. That is, as the coherence length is longer, measurement accuracy may increase. Accordingly, a laser light source in which the spectral bandwidth of the light source is less than a predetermined reference bandwidth may be used as the laser source unit 31, and the measurement accuracy may increase as the reference bandwidth is shorter. For example, in order to measure the pattern change of the laser speckle, when irradiating light into the culture dish every reference time, the spectral bandwidth of the light source can be maintained below 1 nm.

On the other hand, for example, as shown in Figures 2 and 3, the frame (F), the inner surface corresponding to the tube device 40 is formed therein, the inner surface is to scatter the laser light A light scattering surface (T) or a reflective surface may be formed.

The frame (F) may be made of a double material in which the outer surface is made of a resin or ceramic material, and a metal layer (M) or a mirror layer is formed on the inner diameter surface.

In addition, the frame (F) may be made by coating the scattering materials that can cause scattering on the inner surface.

However, it is not necessarily limited thereto, and the frame F may be made of a metal material having excellent reflectivity as a whole.

Here, in order to align the tube device 40, an alignment groove H into which the ring-shaped alignment protrusion A of the tube device 40 is inserted is formed in the first inner surface and the second inner surface. Can.

Therefore, after placing the tube device 40 between the first frame F1 and the second frame F2, the first frame F1 and the second frame F2 are fastened to the tube. The device 40 can be used disposable.

At this time, it is possible to align the alignment protrusion (A) with the alignment groove (H) to align the correct position of the tube device (40).

Subsequently, when the tube device 40 is used and then discarded, the tube device 40 can be easily removed by separating the first frame F1 and the second frame F2.

Here, for this purpose, the frame F may further include a fastening device 50 for fastening the first frame F1 and the second frame F2.

In addition, as shown in FIG. 3, in order to increase the speckle pattern generated by multi-scattering, the main light path or the light incident part 31a of the laser source part 31 is formed so as to form the main light path in a zigzag shape as long as possible. ) May be formed to be inclined at a first angle K1 toward the camera unit 32 based on the vertical direction of the frame F. Here, for example, the first angle K1 may be 0 to 90 degrees.

Accordingly, as shown in FIG. 3, the laser light L emitted from the light incident part 31a is scattered several times through the light scattering surface T and reflected by a zigzag, resulting in speckle pattern generated by multiple scattering. In this maximized state, light may be emitted to the light output unit 32a.

At this time, the light incident portion 31a and the light output portion 32a may be formed to be spaced apart by a first distance L1 in the longitudinal direction of the frame F.
