Description

Chemical discharge micro adjustment device

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a chemical liquid discharge micro adjustment device for arbitrarily adjusting high precision chemical liquid supply in a device for supplying various chemical liquids.

Maintaining a constant blood drug concentration by continuously maintaining the micro-drug in the body has become a very important factor in the treatment of patients.

In particular, patients with chronic diseases or exhausted severity patients are given drug release by attaching sustained release riders or devices outside of the body in order to maintain a stable and stable concentration of the drug.

As the most commonly used device, a valve device having a pressure control means is installed in the drug supply conduit so that the flow of the conduit can be controlled by pressure control, thereby enabling macro adjustment.

In the case where the chemical liquid is supplied in the micro unit or less, such a means cannot be employed, and thus the release rate control by the conduit resistance is made by using a micro-conduit.

In other words, because a conduit having a diameter of less than one microunit is employed, precision is given to drug penetration due to a difference in the passage resistance of the conduit, but special techniques are required for the processing of the micro-conduit.

In another method, the opening degree of the discharge opening is controlled to control the passage amount, but the system for controlling the opening degree is composed of high precision parts, which is difficult to manufacture and frequently occurs.

The present invention is to assemble the control plate rotatable inside the case of the upper and lower symmetrical structure on the flow guide base plate to set the opening ratio of the flow guide tube according to the degree of rotation of the control plate, and at the same time stepwise setting by the elastic indicator By providing an adjustment device that allows fine adjustment of sound and tactile settings, not only the production cost is reduced but also the fine adjustment of micro units is excellent, so that anyone can precisely control the emission.

The number of installation of the fixed frame 24 is determined according to the circumference of the circumferential frame 23, and should be installed in at least four directions of front, rear, left and right. The fixing plate 20a is a structure that is symmetrical with the upper and lower fixing plates, and the difference is that the vertically protruding plate is arranged to alternate with the fixing plate of the upper plate.

The projections 26 are formed over the entire circumference of the upper and lower fixing plates 20 and 20a so that the end grooves 51 of the elastic indicator 50 are fitted.

The upper and lower cases 30 and 30a of the present invention have a hemispherical cross-sectional structure in which a cylindrical protrusion 32 is formed, starting from the vertex toward the inner side, and the annular insert 31 is formed up to the end 33 at the tip. Another end 34 is formed on the inner circumferential surface so that the flexible conduit 100 inserted into the central shaft 14 is inserted and fixed. An inner circumferential protrusion 36 is formed on the inner side surfaces of both side ends 35 of the case, and the stop protrusions 37 are formed on the upper end surfaces of both side ends, and the stop protrusion 43 of the upper side 44 of the base plate 40. It is formed to be long enough to take.

The lower case 30a of the same form is formed in such a length that the stopper 37a can be caught with the stop protrusion 43a of the lower side 45 of the base plate 40.

The stopper 37a of 30a is comprised so that it may be caught by both the start part 44a and the end part 44b.

In the elastic indicator 50 of the present invention, the diameter and height of the cylindrical portion 52 in the center are formed to be assembled with the annular insertion portion 31 in the center of the case 30. It was formed more sharply.

The operational relationship according to the above structural features will be described.

As shown in FIG. 1, the damper 1, the adjustment plate 10, the fixed plate 20, the elastic indicator 50, and the case 30 are sequentially assembled to the base plate 40. Insert the flexible conduit 100 into the central axis 14 of the adjustment plate 10 and then passes through the cylindrical projections 32 and 32a of the upper and lower cases 30 and 30a.

An elastic indicator 50 is inserted into the central shaft 14 between the upper fixing plate 20 and the upper case 30 so that the distal groove 51 is caught by the protrusion 26 of the upper fixing plate 20.

The upper and fixing plates 20 and 20a fasten the adjustment plates and the dampers therein while the fixing protrusions 25 and 25a are caught by the circumferential frames 23 and 23a of each other. In addition, the upper fixing plate, the outermost portion of the circumferential frame (23) (23a) is pressed to the base plate (40) while the inner projection (36) of the upper and lower cases (30) (30a) is integrally integrated.

In such an assembled state, the upper case 30 can be rotated 360 ° without being caught by the stop protrusion 43 of the base plate about the central axis 14, and the chemical liquid of the upper control plate 10 according to the degree of rotation. Since the position where the flow path 13 and the chemical liquid flow path 44 of the base plate are different from each other is different, the width of the chemical liquid flow path 44 of the base plate is different.

That is, when the upper plate 30 is fixed to rotate at an arbitrary position, if the width of the chemical liquid flow path 13 of the chemical liquid flow path 13 of the phase control plate is different, the amount of the chemical liquid flow is also different.

That is, when the upper plate 30 is rotated and fixed at an arbitrary position, the chemical liquid flow path 13 of the upper control plate communicates with the chemical liquid flow path 44 of the base plate, so that the width of the chemical liquid flow path 44 of the base plate ( Diameter of the drug solution is controlled.

The chemical liquid flow passage 13a of the lower adjustment plate 10a communicates with the lower side of the lower chemical liquid flow passage 44a of the base plate 40, but the radius of rotation of the lower case 30a is the start portion 43a and the end portion. Limited between (43b) to allow only opening and closing.

When the upper case 30 is rotated, the elastic indicator 50 also rotates together, and the chemical liquid discharge amount can be set by passing sound and resistance while passing through the multi-stage protrusions 26.

The present invention is assembled by placing the upper case (30) (30a), the upper and lower fixing plates (20) (20a), the upper and lower adjustment plates (10) (10a) and the upper and lower dampers (1) (1a) in pairs. It is economical to manufacture and assemble twice as many parts with 1/2 mold.

In addition, by appropriately rotating the upper case 30, the amount of chemical liquid flow through the chemical liquid flow can be controlled to a very small amount. Particularly, the turbulence of the turbidity caused by the elastic indicator 50 being rotated is repeated, so that the user can visualize the degree of drug administration opening. Of course, it can also be detected by sound, and the rotation can be made in stages to allow more precise settings. Furthermore, the upper case 30 of the rotating frame has a fixed function of the elastic indicator 50, so there is no reverse rotation or forward rotation, thereby preventing weakening accidents such as overdose of the drug during use.

If the user rotates the lower case (30a) if necessary, the drug flow is immediately blocked, even in an emergency situation that may occur without ejection of the injection is possible.
