Description

Portable viscosity measuring device

The present invention relates to a portable viscosity measuring device for measuring viscosity according to the velocity of a falling object falling in a viscosity measuring fluid, which is simple to use and can be measured even with a trace amount of the viscosity measuring fluid. .

Viscosity of a fluid is a property of the fluid that resists flow as it flows.

Viscosity of the fluid is an important factor indicating the flow characteristics of the fluid, such as blood, paint, ink, lubricating oil, liquid food or medicine, and is used for fluid analysis by measuring the viscosity or viscosity coefficient with a viscometer.

In most cases, the viscosity of the fluid needs to be measured immediately after the fluid is collected, and the viscosity is analyzed to analyze the fluid.

In particular, the viscosity of blood has been used as an important item in the diagnosis of vascular disease, which is increasing recently. In addition, the viscosity of the blood from time to time to measure frequently in everyday life to prevent disease or cope with the early stages of risk, the need for a viscometer that can be easily and simply measured even by ordinary individuals, in fact such products are being developed.

As a viscosity measuring method applied to a viscosity measuring apparatus, there is a method of freely dropping a falling body in a fluid and measuring the speed of the falling body.

The dropping method uses a phenomenon in which the dropping speed is different depending on the viscosity of the fluid, and as described in Japanese Patent No. 4701442, it is configured to operate the blood collection tube containing the dropping body upside down, and after collecting the blood, reverses it. The falling body falls freely in the blood, and the end velocity or acceleration of the falling falling body is detected to measure the viscosity. In addition, in Korean Patent Registration No. 10-1458320, after suspending a plurality of fine particles by using an excitation means, the terminal sedimentation velocity is detected to measure the viscosity. In addition, in Korean Patent Laid-Open Publication No. 10-2015-0069221, the solution to be measured is sucked into the capillary tube according to the capillary phenomenon, and then the drop is dropped in the capillary tube to measure the viscosity.

However, the above-mentioned conventional techniques are difficult to use because of the large size of the device, and the usage for the measurement is difficult for the general person to easily use, and the manufacture of the tube for containing the solution to be measured is complicated. May be accompanied by an increase in the cost of single use.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described to be easily carried out by those of ordinary skill in the art.

1 to 3, a portable viscosity measuring device according to an embodiment of the present invention includes a transparent hollow tube-shaped capillary tube 10 and a capillary tube 10 for sucking a fluid to be measured in a capillary phenomenon. It is inserted in a replaceable manner, and the position of the capillary 10 is inserted, and the suction of the fluid to be measured for viscosity is performed by manipulating the body 100 and the body 100 to measure and output the viscosity. It is configured to include a stand 200 for use for the purpose of adjusting the viscosity of the main body 100 to the appropriate value or to measure the viscosity according to the expected viscosity of the fluid to be measured or viscosity.

1 to 3 show the sequence of viscosity measurement using the portable viscosity measuring device according to the present invention, according to the body, through the insertion port 101 except for the lower portion of the capillary tube 10 as shown in FIG. 2, and then as shown in FIG. 2, the operation projection 124 of the operation lever unit 120 is operated to suck the viscosity measurement fluid into the capillary tube 10, as will be described later. . Then, as shown in Figure 3 is inserted into the main body insertion hole 223 formed in the mounting portion 220 of the pedestal 200, and confirms the viscosity measurement results output to the display 154. More specific viscosity measurement procedures include angle adjustment and stripping operations as described below.

The capillary tube 10 is a hollow tube which allows the fluid to be measured for viscosity to be sucked into the inside by capillary action, as shown in the cross-sectional view of FIG. 4. The internal air is discharged through the upper opening to facilitate fluid inflow by capillary action. And the material is satisfied if it is a transparent material that can see the inside from the outside visually, for example, may be made of glass.

In addition, the upper peripheral inner peripheral surface of the capillary 10 is provided with a dropping body 11 of at least a diameter smaller than the inner diameter to be able to freely fall inside the capillary 10.

Here, the shape of the dropping body 11 may not be limited to any one shape, for example, it may be spherical shape, cylinder shape, square shape, etc., Preferably it is spherical shape or cylindrical shape is good.

By the way, since the falling body 11 will make the viscosity-measured fluid fall freely in the state which inhaled the inside of the capillary 10, it is good to have an appropriate weight in view of the expected viscosity range of the viscosity-measured fluid. Furthermore, since the proper inner diameter of the capillary tube to be sucked into the capillary phenomenon is required depending on the type of the fluid to be measured, the inner diameter of the capillary 10 and the size / weight of the drop 11 depend on the type of the fluid to be measured. It is a good idea to set a suitable value. As a specific example, when the fluid to be measured viscosity is blood, the inner diameter of the capillary tube is 0.9 to 1.1 mm, and the falling body is made of Fe, Ni, Co, or the like having a diameter of 0.6 to 0.8 mm, or stainless steel. It can be made into a spherical metal.

For example, when the fluid to be measured for viscosity is blood, at least one in the group containing bovine serum albumin, sodium hydroxide, sodium chloride, sodium citrate, sodium acetate, potassium phosphate, potassium nitrate, glucose and lactose monohydrate It can be selected and used as the compound. The method of fixing the drop member 11 in the capillary tube may be performed by putting the drop member 11 coated with the compound on the surface into the capillary tube 10 and freeze drying.

As another example, when the fluid to be measured for viscosity is a petroleum product, the compound may be selected and used as appropriate among lipophilic compounds.

On / off button 152 for (on / off), the display unit 154 for outputting information by installing on the upper surface of the upper portion (100c) formed inclined backward with respect to the intermediate portion (100b), to inform the operation state Lamps 153 for the same.

Looking at the overall appearance of the main body 100, the lower portion (100a) into which the capillary tube 10 is inserted is arranged along the capillary tube 10, the sensor unit 130, guide unit 140 and lighting unit 170 to be described below It is configured to be as thin as possible, the relatively bulky operation lever 120, the upper and lower buttons 151, the on-off button 152, the signal processing unit 180, the intermediate portion is mounted, such as the power supply 160 100b is configured to be thin enough to be easily gripped and manipulated by hand while accommodating the components to be mounted up and down. The upper part 100c on which the display unit 154 is mounted should have a sufficient area in consideration of the readability of the screen output to the display unit 154, so that the thickness thereof is thin and has a relatively large area rather than the lower and middle parts. It was set as. This is suitable for portable.

The internal structure of the main body 100 will be described in detail in the order of the lower part 100a, the middle part 100b and the upper part 100c.

The lower portion 100a of the main body 100 is provided with an elongated inner passage through which the capillary 10 is inserted through the insertion hole 101 to be accommodated as shown in FIGS. 5, 7 and 8.

In addition, a plurality of sensor units 130 are disposed in the inner passages of the lower portion 100a to respectively detect the falling bodies 11 falling in the capillary 10 at different positions (different heights). That is, when the capillary tube 10 is inserted into the main body 100, a plurality of sensor units 130 are disposed at different heights below the drop body 11 to sequentially detect the drop of the drop body 11. .

Here, the sensor unit 130 is satisfied if it can detect the falling body 11, in a specific embodiment of the present invention comprises a light emitting unit and a light receiving unit facing each other with a capillary tube 10 therebetween To detect the time when the light irradiated toward the light receiving portion is disturbed by the falling body (11). As another example, the magnetic field sensor may be configured to detect the point of time when the magnetic field is disturbed by the drop 11.

In addition, the plurality of lighting units 170 are disposed along the insertion portion of the capillary tube 10 so that the capillary tube 10 illuminated by the lighting unit 170 can be seen from the outside through the viewing window 102.

In addition, in order to stabilize the thin capillary 10, a guide part 140 having a hole through which the capillary 10 penetrates is inserted to be inserted across the inner passage.

The upper end of the inner passage of the lower portion (100a) of the main body 100 is provided with a holding portion 110 for holding the upper side of the capillary (10) inserted into the inner passage.

6, 8, and 9 is inserted into the inner passage of the lower portion (100a) of the main body 100 as shown in Figure 6, 8, 9 to pass through the upper portion of the capillary tube 10 is received in the inner space 111 , Is formed as a tubular body that is in close contact with the outer circumferential surface of the capillary tube 10 to be penetrated. In addition, the inner space 111 of which the upper portion is opened has a larger inner diameter than the outer diameter of the capillary tube 10, and the discharge passage 112 is formed at a point in the front direction of the inner circumferential surface so that the inner space 112 is opened. Can be communicated with.

Here, the gripping portion 110 is made of a material having rubber elasticity (rubber elasticity), such as silicone rubber or rubber, in close contact with the outer circumferential surface of the capillary tube 10 penetrating through the lower hole, and closes the upper opening. By close contact with the outer circumferential surface of the operation lever 120 to insert a portion into the inner space 111 through, the upper opening of the capillary 10 placed in the inner space to communicate with the outside only through the discharge passage 112. To be able.

On the other hand, the hole through which the capillary tube 10 penetrates toward the internal space 111 from the gripper 110 is formed to have a narrower inner diameter, so that the capillary tube 10 can be easily penetrated. Moreover, the insertion guide part 114 which guides the capillary tube 10 to the hole was added to the outer side of the hole. Here, the insertion guide portion 114 is provided with a hole whose inner diameter is gradually narrowed down to approximately the size of the hole of the gripping portion 110.

In addition, in order to prevent the gripping portion 110 from rotating together when the operation lever 120 inserted in the internal space 111 through the upper opening of the gripping portion 110 rotates, FIGS. 6 and FIG. As shown in FIG. 9, protrusions 113 facing each other are formed around the discharge passage 112 among the outer circumferential surfaces of the grip part 110, and protrusions 104 fitted between the protrusions 113 are provided in the main body 100. ) On the inner circumferential surface. At this time, the protrusion 104 is provided with a groove 105 extending into a position communicating with the discharge passage 112 and out of the outer circumferential surface of the grip portion 110 to connect the discharge passage 112 with the space inside the main body 100. .

The actuating lever part 120 inserts a lower portion into the inner space 111 of the grip part 110 through an upper opening of the grip part 110 to seal the inner space 111, but holds the grip part 110. It can be rotated about the vertical axis by the material property of). In addition, the outer circumferential surface of the lower side portion inserted into the inner space 111 extends up and down, and the opening / closing groove 121 that maintains a state of communication with the inner space 111 of the gripper 110 is always discharge passage 112. It is formed to the height of).

Thus, the internal space 111 is in communication with the outside when the opening and closing groove 121 is aligned with the position of the discharge passage 112, and when the opening and closing groove 121 is displaced to the discharge passage 112, it is blocked from the outside, the operation The lever unit 120 may open and close the discharge passage 112 by adjusting the rotation angle.

In addition, an upper portion of the capillary 10 accommodated in the inner space 111 is shown at a portion inserted into the inner space 111 of the holding part 110 by the operation lever 120. The protrusion removal strip 122 of the protrusion shape which contact | connected with is formed. The removal protrusion 122 restricts the insertion depth when the capillary tube 10 is inserted into the main body 100, while lowering the operation lever 120 to push the capillary tube 10 downward to hold the capillary tube 110. It is used for stripping away from). The lower end of the removal protrusion 122 is provided with an opening groove 123 extending from the center of the lower end to the outer circumferential surface thereof so as not to block the upper end of the capillary 10 when the upper end of the capillary 10 abuts. .

The upper side of the actuating lever unit 120 includes a protrusion-like operation protrusion 124 that protrudes outward through the lever hole 103 so that a movement range is guided by the lever hole 103.

Here, the lever hole 103 is cut in a predetermined length in the circumferential direction of the middle portion (100b) of the body 100 and then has a shape that is further cut in a predetermined length toward the lower direction at either end, the operation lever The portion 120 is limited to the rotation range and the falling range by the lever hole 103. Of course, the rotation range is a position that allows the opening and closing groove 121 of the operation lever unit 120 to be in communication with each other in accordance with the discharge passage 112 of the holding unit 110 and the opening and closing groove 121 to the discharge passage 112. It is the range which makes a position which does not mutually mutually communicate with each other, and a fall range is set as the range which pushes out the capillary 10 by the removal protrusion 122, and is separated by the holding part 110. FIG.

In a specific embodiment, the manipulation protrusion 124 is fitted into the lever hole 103 in a state covered with the protrusion cover 125. In addition, the projection cover 125 is provided with an extension part which always covers the lever hole 103 when it is operated by a human hand and moves along the lever hole 103. Here, the extension part is provided to be in close contact with the inner circumferential surface of the middle portion (110b) of the main body 100, to stabilize the rotation and vertical movement of the operating lever unit 120 while making the inside invisible from the outside, the lever to make more stable The hole 103, the operation protrusion 124, and the projection cover 125 are provided in two places.

Of course, since the outside of the gripper 110 becomes the internal space of the middle portion 100b of the main body 100 and there is a gap due to the lever hole 103, the internal space 111 of the gripper 110 and Air flow is possible between the outside of the main body 100.

On the upper side of the operating lever unit 120, a signal processing unit 180 for executing an algorithm for calculating or obtaining a viscosity based on the sensing value detected by the sensor unit 130, the interface unit 150 and the power supply unit 170 ) Is placed.

According to a specific embodiment, as shown in FIG. 7, a circuit board 181 having a narrow width extending from the inner space of the intermediate portion 100b to the inner space of the lower portion 100a and extending vertically is provided to provide a sensor unit ( 130, the guide unit 140, the lighting unit 170, the grip unit 110, the operation lever unit 120, the signal processing unit 180, and the power supply unit 160, as well as the up and down buttons in the interface unit 150 ( The mounting process of the present invention is simplified by mounting or mounting the 151 and the lamp 153 on the circuit board 181 according to the placement position. In the case of the on-off button 152, it is attached to the lower side (lower side of the display) of the upper part 100c, and it is easy to operate.

Meanwhile, the signal processor 180 outputs a screen for selecting and inputting an inclination angle of the main body 100 to the display 154 to select an inclination angle with the up and down buttons 151, and the sensor unit 140. When acquiring the viscosity according to the sensed value detected by using the viscosity acquisition algorithm corresponding to the inclination angle selected by the up and down buttons 151 to obtain the viscosity.

The dropping time of the dropping body 11 falling in the capillary 10 is shorter as the fall angle of the capillary 10 with respect to the horizontal plane becomes shorter. On the contrary, the inclination angle of the capillary 10 is reduced with respect to the vertical line. The smaller it is, the shorter the fall time.

Thus, the lower the expected viscosity for the fluid to be measured, the more accurate the viscosity can be obtained by measuring the viscosity by reducing the inclination angle relative to the horizontal plane. This is because the lower the viscosity, the shorter the fall time of the falling body, and the detection error in the sensor portion can be relatively large.

On the contrary, the higher the expected viscosity, the greater the inclination angle relative to the horizontal plane, and the smaller the difference in free fall time compared to the case where the viscosity is low, so that the viscosity can be accurately obtained.

Therefore, the viscosity acquisition algorithm described above may be a algorithm for correcting the viscosity calculation equation according to the slope by measuring the change of the drop time according to the inclination of the capillary tube, as disclosed in Korean Patent Laid-Open Publication No. 10-2015-0069221, for example.

On the other hand, the viscosity equation may be used, for example, the equation described in Korean Patent Registration 10-1458320.

The main body 100 configured as described above may be used alone to measure the viscosity without using the stand 200, and the method of use may be as follows.

First, the operation lever 120 is left in a state of being pushed upward while blocking the discharge passage 112 of the gripping portion (110).

Next, the capillary tube 10 is inserted into the insertion hole 101 of the main body 100 so that the portion provided with the falling body 11 enters first, and the operating lever portion in the internal space 111 of the grip portion 110. Insert the capillary tube 10 until it comes into contact with the removal protrusion 122 of 120. Since the lower end of the capillary 10 (the opposite side of the portion provided with the dropping body) should be exposed to the outside of the insertion hole 101 in the inserted state, the length of the capillary 10 is appropriately manufactured according to the insertion depth to the main body. Should.

Next, the on-off button 152 is pressed to turn on the power. Then, select the slope input. When the following stand 200 is not used, it is difficult to accurately adjust the inclination, so it is preferable to select in the vertical direction.

Next, after immersing the lower end of the capillary tube 10 in the solution to be measured for viscosity, the operation passage 124 is moved by a finger to rotate the operation lever unit 120 to open the discharge passage 112. Accordingly, the internal air of the capillary tube 10 receives the rising pressure of the fluid to be measured by the capillary phenomenon, and thus the opening groove 123 of the operation lever unit 120 and the internal space 111 of the grip unit 110 are operated. Since the liquid is discharged to the outside via the opening and closing groove 121 and the discharge passage 112 of the lever 120, the fluid is sucked into the capillary 11.

Here, since the inflow height of the fluid can be seen through the transmission window 102, the capillary tube 10 by closing the discharge passage 112 by rotating the operation lever portion 120 at the moment when the fluid reaches the falling body (11). The air exhaust path in the) is blocked. As a result, fluid intake in the capillary is stopped. And the main body 100 is upright.

At this time, since the compound in which the falling body 11 is fixed to the inner wall of the capillary 10 is dissolved in the fluid and the falling body 11 falls, the signal processing unit 180 detects the falling body 11 detected by the sensor unit 130. Viscosity is obtained according to the dropping speed of?), And the obtained viscosity is output to the display 154.

After confirming the output viscosity, the user pushes the operation lever 120 downward, thereby disengaging the capillary tube 10 from the gripper 110. Thus, the capillary tube 10 is removed from the body 100.

Hereinafter, the stand 200 will be described with reference to the separated perspective views of FIGS. 1 to 3 and 10.

The stand 200 is to leave the main body 100 in a stable state without moving the measurement of the viscosity or to measure the viscosity in a state adjusted to the appropriate inclination. The stand 200 for this purpose is disposed between the shaft support portion 210, both of the shaft support portion 210, which is protruded upwards at intervals to face each other and is supported by the shaft support portion 210 to rotate the rotating shaft It is configured to include a mounting portion 220 to tilt the 221 to the axis, and the angle adjusting unit 230: 231 to 237 for adjusting the tilt of the mounting portion 220.

Here, the mounting portion 220 has a main body insertion opening 223 which is opened up and down, and allows the main body 100 to be inserted into the main body insertion opening 223 from top to bottom. Here, a stepped portion (not shown) is formed at the lower end side of the inner peripheral surface of the main body insertion port 223 so that the lower portion 100a of the main body 100 passes and the middle portion 100b of the main body 100 extends. That is, at least from the viewing window 102 to the insertion hole 101 of each portion of the main body 100 is exposed to the lower side of the mounting portion 220 should be visible from the outside.

In addition, the mounting portion 220 has an extension portion 222 extending downward to surround the rear side of the lower portion (100a) of the main body 100 at intervals. Preferably, the lower end of the extension portion 222 has a small sump-shaped drip groove 224 to pool the fluid falling from the capillary (10). The liquid receiving groove 224 inserts the capillary tube 10 and the capillary tube 10 when the main body 100 is inserted into the holder 220 in a state where the fluid to be measured is sucked into the capillary tube 10. It is intended to contain fluids that may fall off, to facilitate subsequent flushing.

According to a specific embodiment, the mounting part 220 is configured to fix one rotation shaft 221 on each side of the transverse direction perpendicular to the vertical direction in which the main body 100 is inserted. In addition, the rotating shafts 221 on both sides are rotatable in a state of penetrating the shaft support portion 210, respectively.

A departure prevention plate 211 penetrates through an end of the rotation shaft 221 on the outer surface of the bearing portion 210. The shaft departure prevention plate 211 is fixed to the shaft support portion 210 while allowing the rotation of the rotation shaft 221 to prevent the departure of the rotation shaft 221, and to determine the rotation angle of the rotation shaft 221 from the outside . That is, since the rotation angle of the rotating shaft 221 is the rotation angle of the mounting portion 220 or the inclination angle of the main body 100 mounted on the mounting portion 220, the description of the capillary tube 10 inserted into the main body 100 is described.

The inclination angle of the part 220 is engraved so that the indicator line 232 is pointed according to the rotation of the rotary shaft 221, the scale 231 is interposed between the bearing portion 210 and the mounting portion 220, but the mounting portion 220 ) Is fixed to the rotating disk 233, a plurality of holes 234 formed along the circular arc centered on the rotating shaft 221, the shaft support portion 210 is fixed to the rotating shaft 221, the rotating disk 233 The hole 234 is inserted into the hole 234 is changed according to the rotation of the), the projection 236, which is formed in the mounting portion 220, is formed in the shaft support portion 210 to be caught by the projection 236 It includes a stop projection 237 to limit the rotation range of the mounting portion 220.

Here, the hole insertion protrusion 235 is elastically contracted with respect to the pressing or elastically pushed toward the inside of the bearing portion 210, so that the mounting portion 220 can be rotated by hand. Of course, if you put your hand in the state inserted in the hole 234, the stopper 220 is stopped so as not to rotate unless artificially rotated.

In addition, while the composition position of the plurality of holes 234 formed on the rotating disc 233 and the marking position of the graduations engraved on the shaft deviation preventing plate 211 correspond to each other, the inclination angle of the mounting portion 220 and Also correspond. The angle here is, for example, the angle to the horizontal plane in the range of 20 ° ~ 90 °, the hole 234 and the scale 231 can be configured to fit the positions of 20 °, 30 °, 45 ° and 90 °. And, this adjustment angle is matched with the angle selected by the main body 100.

The usage of the stand 200 configured as described above is to tilt the mounting portion 220 at the same angle as the tilt angle selected and input to the main body 100, and at least a dropping body in the capillary 10 filled with the fluid to be measured for viscosity. 11 is the same as the single use of the main body 100 except for mounting the main body 100 to the mounting portion 220 before falling.
