In particular, in the present invention, in order to measure the correct dose of the chemical solution to the patient, which is the most caution when injecting the chemical liquid, a ruler is displayed on the outer circumferential surface of the casing or the rotating body and the elastic tube inside the casing is expanded. The rotating body rotates at an angle according to the degree of expansion thereof, and when the liquid solution is administered so that the elastic tube inside the casing contracts, the rotating body rotates in a direction opposite to the rotational direction at the time of expansion. The change amount of the chemical liquid inside the tube can be accurately measured, and the range of the ruler is large so that it is related to the chemical liquid injector having a rotating scale so that even a person with low vision can easily check.

In general, the medicine injector ensures that a certain amount of medicine is always correctly and accurately administered without special control when administering special painkillers and antibiotics, and also temporarily administers a large amount of medicine according to the condition of the patient to treat the patient. One medicine injector is called so that it can be made efficiently.

A special antibiotic is administered to a patient such as cancer or leukemia, and a patient who is constantly suffering after surgery is given a painkiller at a fixed time period to alleviate the pain. In this case, a medicine injector such as the present invention is used. . Of course, even in procedures such as hemorrhoids and tonsillitis, which will cause severe pain for a long time through direct treatment, painkillers are used to inject the medicine to reduce pain after surgery.

Therefore, these chemical injectors are being used in various forms nowadays, and look at the typical conventional patents of them look at the problems.

As shown in Figures 1 and 2, the conventional invention is in the state that the chemical solution is not contained in the chemical storage means 200, as shown in the drawing by the elastic force of the chemical storage tube 230, the movable shaft 220 is It is maintained in the state accommodated in the fixed tube (210).

When the chemical solution is stored in the chemical storage tube 230 in the above state, as shown in FIG. 2, the cap 440 fastened to the injection tube 420 is released to the injection tube 420 opened. When the pressure is inserted into the syringe containing the chemical liquid, the elastic tube 430 of the elastic tube which is in close contact with the inner circumferential surface of the connecting tube 410 as shown in the dotted line due to the pressure of the chemical liquid injected into the injection tube 420 As the chemical liquid is introduced into the fixed tube 210 through the space formed between the connecting tube 410 and the elastic tube 430, the moving shaft 220 stored in the fixed tube is pushed backward due to the pressure of the chemical liquid. The elastic chemical liquid storage tube 230 which is fixed to each end of the fixed tube and the moving shaft is forcibly stretched while being covered on the outer periphery of the fixed tube, and the fixed shaft 210 as the moving shaft retreats. The drug solution is supplied to be immersed in the drug solution storage tube 230 going out of the exit gojeonggwan through holes 211 that are configured on the outer periphery side of the gojeonggwan.

At this time, when the chemical liquid storage tube is inflated according to the injection amount of the chemical liquid, the end of the chemical liquid storage tube is moved in a state that is firmly coupled to the moving shaft by an elastic rubber ring (fixing ring). According to the liquid amount, the elastic chemical liquid storage tube 230 is maintained in an expanded state as shown in FIG. 2, and the amount of the chemical liquid to be injected is checked by the scale marked on the case 100 to measure the amount of the chemical liquid to be injected. Will be.

When the injection of the chemical solution is completed in the above state to close the cap 440 to the injection tube 420, at this time the elastic tube 430 pushed back by the pressure of the injected chemical liquid is returned to the original connection pipe 410 By close contact with the inner circumferential surface of the) to close the injection tube 420 so that the chemical flow back from the fixed tube 210 is not leaked to the outside through the injection tube (410).

By the way, the following problems occur in the conventional chemical liquid injector. A short and wide ruler is shown on the outer circumferential surface of a narrow length of the case at regular intervals, and the dose is read according to the amount of variation of the reducing chemical storage tube, which is not accurate.

In addition, the ruler can show the ruler only at the linear moving distance of the elastic tube, so that the length of the entire ruler is short and the interval between the detailed scales cannot be shown in detail. In the end, measuring the amount of chemical change through an invisible and unclear ruler is less accurate.

The present invention relates to a drug injector. Therefore, the configuration of the present invention and its operation will be described in detail with reference to FIGS. 3 to 9.

As shown in the figure, the present invention has a casing 50 consisting of a top plate 10 and a bottom plate case 30 for closing and closing the bottom of the lower case 20 and the lower case 20 in a cylindrical upper and lower portions are opened. In addition, there is a cover panel 60 having an open drug inlet 61, fitted in the top opening 11 of the upper case 10 to close the top, drug injection hole 61 of the cover panel 60 There is an elastic tube (65) inserted into the casing (50) in communication with. In addition, there is a rotating body 40 accommodated inside the casing 50 and rotating horizontally through the rotating rod 41 protruding from the center. Therefore, the combination of the rotating body 40 rotates the amount of change generated in the elastic tube 65 in accordance with the injection and discharge of the drug, the "marker" formed on the outer peripheral surface and the rotating body 40 of the lower case 20 It can be detected in the horizontal direction.

And the "tick mark" is the corresponding ruler 21 formed on the ruler 21 and the rotating body 40 formed at regular intervals on the outer peripheral surface of the casing 50 or on the outer peripheral surface of the rotating body 40. It is preferable that it is a ruler formed at regular intervals and a corresponding point scale formed on the outer circumferential surface of the casing 50.

The main feature of the present invention is that the scale mark is formed in the vertical direction (= landscape direction), and the mark is read and measured in the horizontal direction. The meaning of the term "tick marker" described in the present invention is as follows. Graduation marker is an example of a graduation inscribed at regular intervals on the outer circumferential surface of a syringe or beaker. In addition, the amount of drug injected into the syringe corresponding to this scale may be another scale and become a "point scale". In fact, when measuring and measuring the amount of material contained in any container, beaker or syringe, there should be a ruler shown on the outer circumference of the syringe, and the point scales for illuminating the amount on the ruler inside the syringe correspond to each other. Express the quantity. In the present invention, the "tick mark" refers to a mark that collectively covers both the "ruler" on the outer circumferential surface of the syringe and the "point scale" which is the physical quantity of the drug inside the syringe.

The present invention is a kind of measuring instrument that reads the scale, reads the scale, and measures the amount of the contents, and in particular, the way of reading the scale mark is horizontal (= horizontal) unlike the beaker and syringe described above. to be. To this end, in all the drawings of the present invention, the tick marks are divided into rulers and point scales. 3 to 9 of the present invention shown in the outer circumferential surface of the casing is called a ruler and the scale engraved on the rotating body is called a point scale. These are all tick marks indicating the amount of change in the chemical solution.

Of course, although not shown in the drawings of the present invention, another embodiment of the "scale marker" in which the ruler is engraved on the outer circumferential surface of the rotating body 40, the casing 50 is engraved point is also the scope of the present invention. However, in the following description, the unit formed on the outer circumferential surface of the casing 50 will always be referred to as the ruler 21, and the scale engraved on the rotating body 40 will be referred to as the point scale 20. It should also be noted that all of these are referred to as “tick marks”.

The greatest feature of the present invention is that, as mentioned some, the ruler 21 is formed in the transverse direction of the casing 50 so that the width of the scale is wide. The reason why the configuration of the ruler 21 is important is that the conventional chemical liquid injector is hard to engrave a large number of scales within a narrow range for the majority of the rulers to be placed in the longitudinal direction of the case. As a result, accurate measurement of drug infusion was difficult. However, the present invention can be formed around the outer casing 50 of the round drug injector long, so that the interval between the graduations can be formed wider, and the graduations can be more delicate.

To this end, the present invention separates the casing 50 forming the outer case into the upper case 10, the lower case 20 and the bottom plate case 30, and combine them to form one. The upper case 10 and the lower case 20 has a cylindrical shape opened in the upper and lower directions, the cover panel 60 is configured to cover the upper end of the upper case 10. As shown in FIG. 3, the cover panel 60 is provided with a drug inlet 61 so that drugs are injected into the inner elastic tube 65 through the drug inlet 61. In order to use this injector, an appropriate amount of drug required by a patient must first be injected into the elastic tube 65 inside the injector. The drug injector of the present invention (= chemical injector; hereinafter used in combination) is first injected into the inside of the elastic tube 65, and then the hose to the outlet 63 in the state of blocking the injected inlet 61 It is used in the form of connecting the needle and inserting the needle into the affected or skin tissue of the patient. In this case, the important point is the amount of the injected chemical solution. It must be accurately calculated and infused, and even after infusion, the measurement of the drug that has exited the patient must be accurate.

The present invention is intended to check the amount of change of the chemical liquid corresponding to the ruler by embedding the rotating body 40 shown in the casing 50 for this purpose. As shown in FIG. 4, when the point scale 22 is engraved on one side of the rotating body 40 and the point scale 22 moves while rotating, the chemical solution is checked by engraving the scale on the outer casing 50. It is to measure the quantity. Figure 4 shows this action in detail, in Figure 4 (a) it is seen that a small amount of the chemical liquid is filled inside the elastic tube 65 inflated with a small balloon. However, when the amount of the chemical liquid is filled inside the elastic tube 65 and expands to a large volume, the rotating body 40 rotates in accordance with the degree of expansion of the inflatable elastic tube 65. It becomes the state of 4 (b). That is, the point scale 22 rotates and moves.

In this very simple way, the chemical liquid of the present invention can measure the amount of change.

Then look at the embodiment of the present invention through a more detailed configuration.

That is, as shown in Figure 3, the lower end of the injection hole 61 of the cover panel 60, there is a funnel-type injection nozzle 62 is inserted directly below the injection hole 61, fastening to the lower end of the injection nozzle 62 There is a distribution pipe 64 having a discharge port (63) for providing a passage to the chemical liquid, there is a coiling 66 is fastened to the end of the distribution pipe 64 to enable the interlock in the vertical direction. In addition, there is an elastic tube 65 fastened to surround the outer circumferential surface of the coil ring 66. These are combined with each other to become a vertical interlocking means (A). In the vertical interlocking means, the elastic tube 65 swells and extends in length as the chemical liquid increases and decreases to extend the coiling 66 in the longitudinal direction.

The chemical liquid injector of the present invention will expand as long as the elastic tube 65 is expanded, and the amount of change of the chemical liquid inside the elastic tube 65 by rotating the rotor 40 by this expanded length. Was intended to be represented by the ruler 21. Therefore, first, the length of the chemical liquid injected or exited from the inside of the chemical injector, the length should be converted into a horizontal rotational movement to increase or decrease.

As a result, the vertical interlocking motion is converted into a horizontal rotational motion, which should be displayed at intervals of the physical ruler 21.

In the present invention, the vertical interlocking means (A), as described above, refers to a means for achieving a movement that is reduced in length and stretches by the amount of the chemical liquid injected or exited from the inside of the chemical liquid injector. The components of this vertical interlocking means (A) consist of the injection nozzle 62, the distribution pipe 64, the coiling 66, and the elastic tube 65 as described above.

The elastic tube 65 repeats the volume expands and contracts when the chemical liquid is filled or exited. This is because the chemical liquid changes in volume in the elastic tube 65. As an example, a process of filling the chemical liquid into the elastic tube 65 will be described below. The manner of operation of the vertical linking means A of the present invention is as follows.

The chemical liquid supply hose (not shown) is inserted into the injection port 63 of the cover panel 60, and the chemical liquid is injected at a high pressure. This operation is illustrated through FIGS. 4 and 5, where the chemical liquid is injected, the elastomer tube 65 is shaped like a small bag, as in FIG. 4A, and the casing 50 as in FIG. 4B. It will change into a large tube filled with). At this time, the elastic tube 65 has a cylindrical body, and is wrapped around the coiling and fastened. More precisely, the upper end of the cylindrical elastic tube 65 is firmly fastened between the distribution tube 64 and the fastening ring 91, and the lower end of the elastic tube 65 is at the end of the coil ring 66. It is in a closed state through the other fastening ring 91. Eventually, when the chemical liquid is injected through the injection hole 61, the chemical liquid passing through the injection hole 61 passes through the injection nozzle 62, and enters the passage to fill the coiling to inflate the elastic tube 65. As the injection amount increases, the elastic tube 65 expands like a balloon to expand the volume. The lower end of the elastic tube 65 is fastened to the coil ring 66, so that the lower end thereof is in a closed state, thereby expanding and expanding into the elastic tube 65.

At this time, the matter to be noted is the coiling 66. This coil ring 66 refers to a ring which is twisted in a circle like a telephone line and is free of extension of its length. It is made of synthetic resin material with a slightly higher hardness and can be elongated while being twisted in a circular shape, but when the pulling tension is removed, it is restored through its elastic force and changed into a short length. Therefore, when the elastic tube 65 of the present invention expands and its length also increases, the length of the inner coiling 66 also extends, as shown in FIGS. 4 and 5 (b). The configuration that plays this role is the vertical interlocking means (A) of the present invention.

Then, when the length is increased through the vertical interlocking means (A), the length expansion can be displayed through the ruler 21 by means of changing the vertical movement into the horizontal rotational movement. Rotating means (B).

That is, at the end of the coil ring 66, there is a vertically long hat-shaped screw tube 52 inserted into the circular coil ring 66 and having a screw groove 51 on the inner circumferential surface thereof. 40 is fitted to the end of the rotating rod 41 protruding from the center, there is a rotary tube 54 having a screw protrusion 53 protruding to the outer peripheral surface thereof becomes a rotating means (B). In the state in which the rotary tube 54 is screw-coupled to the inner side of the screw tube 52, the rotary tube 54 is rotated in the screw tube 52 in accordance with the increase and decrease of the chemical liquid, and then the lower and lower the rotary body ( 40) to rotate.

Components of the rotating means (B) is largely composed of a screw tube 52, the rotary tube 54 and the rotating body (40). As described above, a cap-shaped screw pipe 52 is fitted to the inner circumferential surface and fastened to the end of the coil ring 66. The elastic tube 65, the screw tube 52, the coil ring 66 is actually integrally fastened through the external fastening ring 91. Of course, hermeticity is also maintained. Therefore, when the coiling 66 is interlocked by the above-described vertical interlocking means A, the screw pipe 52 is interlocked accordingly. The screw groove 51 shown in the figure is formed in the inner peripheral surface of this screw pipe 52, and the rotary pipe 54 which has the screw protrusion 53 screw-fastened to this screw groove 52 is fitted. As a result, when the screw tube 52 is vertically interlocked according to the interlocking of the coil ring 66 and the elastic tube 65, the rotary tube 54 is rotated. In more detail, when the elastic tube 65 expands to extend its length, the end of the coil ring 66 also extends in length, and the screw tube 52 is disposed at the end of the coil ring 66. Since the screw ring 52 is also fastened through the fastening ring 91, the vertical lifting and lowering motion.

That is, the vertical lifting and lowering motion of the screw tube 52 causes the rotary tube 54 screwed to its inner circumferential surface to rotate. Since the screw protrusion 53 is interlocked with the screw groove 51, the rotary tube 54 rotates by the X axis interlocking distance of the screw groove 51, and the screw tube 52 is increased by the Y axis interlocking distance. Will do the descent exercise. The screw tube 52 is interlocked while rotating the rotary tube 54 by the length of the expansion of the screw tube 52 is considerable. At this time, since the rotary tube 54 is fitted to the rotary rod 41 protruding from the center of the rotary body 40 as shown in the drawing, the rotary body 40 is rotated by the rotation angle of the rotary tube 54. According to this rotation, the filling amount of the chemical liquid can be checked and the injected amount can be measured.

And the upper portion of the rotary tube 54 fitted inside the screw tube 52 has a built-in elastic spring 55, when the rotary tube 54 is moved up and down while rotating inside the screw tube 52, there is a play To compensate. Substantially the screw tube 52 is interlocked in the vertical direction, and rotates the rotary tube 54 fitted in the screw groove (51). At this time, the rotary tube 54 is interlocked in the up and down direction according to the rotation angle, and interlocks with the screw groove 51 of the screw tube 52. To be precise, the screw tube 52 is interlocked with the coiling 66 to be expanded, and the rotary tube 54 only rotates while receiving the linkage. In order to facilitate such interlocking, the elastic spring 55 is embedded in the present invention. The elastic spring 55 is embedded in the upper end of the rotary tube 54 fitted to the screw tube 52, and the elastic spring 55 is interviewed with the upper surface of the inner circumferential surface of the screw tube 52. Then, while the screw pipe 52 moves up and down, it prevents a rattling phenomenon when the rotary pipe 54 is rotated, and the rotary pipe 54 easily rides up and down in the screw groove 51. To do it.

In addition, in the present invention, as described above, three configurations are combined to form the casing 50. These are all combined by special means. That is, the connection of the casing 50 consisting of the upper case 10, the lower case 20 and the bottom plate case 30, the fitting projections corresponding to the vertical direction corresponding to the vertical direction of each case (10, 20, 30) ( 13) and the fitting groove 14 to be formed so that they can be combined with each other.

As shown in FIG. 3, the fitting protrusion 13 protruding from the case where the case and the case are interviewed is formed, and the corresponding fitting case 14 is formed in the corresponding other case. Although FIG. 3 illustrates an embodiment in which a fitting protrusion 13 protruding in a circular shape and a fitting groove 14 corresponding thereto are formed, in FIG. 7, a long groove is formed around the facing portion. That is, the meeting of the fitting protrusion 13 and the fitting groove 14 is not required to have a special form, it is sufficient if they can simply be connected to each other. It also doesn't matter which side is the bump or home.

In addition, the present invention as shown in Figure 3 is coupled to the lower case 20 and the bottom plate case 30, by additionally coupling the coupling ring body 80 for a close connection between the two through a plurality of locking projections 81 Improves its robustness.

Through a plurality of locking projections 81 to be fitted into the fitting groove formed on the outer circumferential surface of the lower case 20, the coupling ring body 80 in a state that is further attached to the connection portion of the lower case 20 and the bottom plate case 30 ). It is possible to fasten more firmly, and the shape of the fastened casing 50 enhances aesthetics more aesthetically. Different color schemes also provide the advantage that the display of the ruler 21 can be more clearly and visually ensured.

In addition, the rotating body 40 accommodated in the casing 50 used in the present invention has a shape in which the lower end is closed by the bottom plate 42 with a cylindrical body 46, and is wedge-shaped in the central portion of the bottom plate 42. A hinge groove 43 having a cross section is formed to accommodate the wedge-shaped hinge protrusion 44 protruding from the center of the corresponding base plate case 30. As described above, the rotating body 40 rotates to align the point scale 22 with the ruler 21. The vertical vertical motion according to the volume expansion and contraction of the elastic tube 65 is converted into a rotary motion. At this time, the means for rotating substantially is the rotating body (40). Therefore, the rotating body 40 should be easy to rotate. At the center of the upper end of the rotating body 40, the rotating rod 41 is rotated by the rotating tube 54, but the lower end is interviewed with the base plate case 30. At this time, there is a possibility that the rotation body 40 may not rotate well due to friction with the bottom plate case 30. In order to solve this problem, the wedge-shaped hinge protrusion 44 protrudes from the center of the inner circumferential surface of the bottom plate case 30 and is inserted into the lower hinge groove 43 of the bottom plate 42. According to this operation, the hinge protrusion 44 becomes a shaft, and the rotating body 40 can be easily rotated.

In addition, by forming a centrifugal line 45 protruding around the outer peripheral surface of the cylindrical body 46 of the rotary body 40 to improve the rotational force of the rotary body 40.
