The supply of the medicine to the medicine analyzer can be performed automatically without

Hereinafter, a drug supply unit applied to a drug analyzer according to other embodiments of the present invention will be described with reference to the drawings.

In carrying out this description, descriptions overlapping with those already described in the first embodiment of the present invention are replaced therewith, and will be omitted here.

8 is an enlarged cross-sectional view of a part of a drug discharge unit applied to a drug accommodating member constituting a drug supply unit applied to a drug analyzer according to a second embodiment of the present invention, and FIG. 9 is an operation of the drug discharge unit of FIG. is a drawing showing

Referring to FIGS. 8 and 9 , the drug supply unit applied to the drug analyzer according to the present embodiment is installed in the drug analyzer for analyzing the drug to supply the drug, and includes a drug accommodating member and a drug supply member. .

The drug accommodating member includes a storage tank and a drug discharge unit 212, and the drug supply member includes a drug supply main body and a drug inlet.

The drug discharge unit 212 includes a drug discharge body 213, a discharge-side movable body, a discharge-side cover 216, a discharge-side sealing body 219, a discharge-side elastic body, and a protruding seal 250. include

The drug discharging body 213 is connected to the accommodating tank, and a discharge-side through-hole is formed in the central portion thereof in a longitudinal direction and communicates with the interior of the accommodating tank.

The discharge-side movable body may be inserted through the discharge-side through-hole and moved in an axial direction of the discharge-side through-hole.

The discharge-side cover 216 is connected to one end of the discharge-side movable body and can open or close the discharge-side through-hole according to the movement of the discharge-side movable body.

The discharge-side cover 216 gradually narrows as it moves away from the discharge-side through-hole and is formed in a conical shape as a whole, and a bottom surface of a predetermined area is connected to the discharge-side cover 216 of the drug discharge body 213. By coming into contact with the facing surface, the discharge-side through-hole may be closed.

The discharge-side sealing body 219 is the discharge-side cover 216 when the discharge-side cover 216 comes into contact with the drug discharge body 213 so that the discharge-side through-hole is closed by the discharge-side cover 216. ) and the medicine discharge body 213 to be sealed.

In this embodiment, the discharge-side sealing body 219 is made of an elastic material and is formed in a hollow shape with an empty inside, and has a predetermined depth on the surface facing the discharge-side cover 216 of the drug discharge body 213. At least a portion is inserted into the recessed groove 213a on the side of the discharge body.

The discharge-side elastic body is disposed between the inner surface of the drug dispensing body 213 and the discharge-side movable body, and provides elastic force to the discharge-side movable body so that the discharge-side movable body can move. can be given as an example.

The protruding sealing part 250 protrudes from the surface facing the drug discharge body 213 of the discharge side cover 216 to seal between the discharge side cover 216 and the drug discharge body 213. will be.

In detail, the protruding sealing part 250 includes a sealing side pressing protrusion 251, a sealing side spaced protrusion 252, and a sealing body support curved surface 253.

The sealing-side pressing protrusion 251 protrudes from the surface of the discharge-side cover 216 facing the discharge body, and is formed in a shape gradually narrowing toward the outside, and is formed by the discharge-side cover 216. When the discharge-side cover 216 moves together with the discharge-side movable body to cover the discharge-side through-hole and approaches the surface of the drug discharge body 213 facing the discharge-side cover 216, the discharge-side sealing This will pressurize the sieve 219.

When the sealing-side pressing protrusion 251 is formed in a pointed shape so that the pressing protrusion presses the discharge-side sealing body 219, the discharge-side sealing body 219 is perpendicular to the direction in which the pressing protrusion presses. It is pressed in an elongated form in the direction (a vertical direction based on FIG. 9).

The sealing-side spaced protrusion 252 protrudes apart from the sealing-side pressing protrusion 251 on a surface of the discharge-side cover 216 facing the discharge body, and the discharge-side cover 216 causes the discharge. When the discharge side cover 216 approaches the surface facing the discharge side cover 216 of the drug discharge body 213 so as to cover the side through-hole, it is inserted into the discharge body side recessed groove 213a. .

When the sealing-side spaced projection 252 is inserted into the discharge body-side recessed groove 213a, the outer surface of the sealing-side spaced projection 252 comes into close contact with the inner surface of the discharge body-side recessed groove 213a. A sealing effect between the discharge side cover 216 and the drug discharge body 213 may be improved.

The sealing body support curved surface 253 is formed with a predetermined curvature at the side facing the outer surface of the discharge-side sealing body 219 among the sealing-side spaced protrusions 252, and is formed on the discharge side by pressing the pressing protrusion. When the sealing body 219 is pressed, it comes into contact with the discharge-side sealing body 219 to support the discharge-side sealing body 219 .

As the sealing body support curved surface 253 is formed with a predetermined curvature, when the discharge-side sealing body 219 is elastically deformed while being pressed, the elastically deformed shape can be guided.

When the protrusion-type sealing part 250 is formed, when the discharge-side cover 216 approaches the medicine discharge body 213, the discharge-side sealing body 219 is elastically deformed by the pressure of the pressing protrusion. In addition, the side surface of the discharge-side sealing body 219 comes into contact with the sealing-side separation protrusion 252, and accordingly, the protruding sealing part 250 and the inner surface of the discharge body-side recessed groove 213a As the contact area between the discharge-side sealing bodies 219 is relatively increased, sealing performance between the discharge-side cover 216 and the drug discharge body 213 can be improved.
