Abstract

The present invention relates to a dual syringe for simultaneously injecting two contents. A cylindrical dual syringe with increased degrees of freedom in the grip direction according to an embodiment of the present invention comprises a syringe housing for filling with contents and a pressure plunger for pressurizing and discharging the contents filled in the syringe housing, wherein the syringe housing includes a partition wall that divides the internal space of the syringe housing into a first filling space and a second filling space to fill different contents, and the pressure plunger comprises a first plunger part that generates pressure in the first filling space to suck in and discharge the contents of the first filling space, a second plunger part that generates pressure in the second filling space to suck in and discharge the contents of the second filling space, and a plunger pressure part for gripping while connecting the ends of the first plunger part and the second plunger part to simultaneously operate the first plunger part and the second plunger part to discharge the contents of the first filling space and the contents of the second filling space simultaneously. The above syringe housing is formed in a cylindrical shape so as not to have a directional orientation for gripping.

  2. In paragraph 1, The above syringe housing is It includes a housing grip portion that protrudes from the circumference of the above syringe housing and hooks a finger to grip, and A cylindrical dual syringe with increased freedom in the gripping direction, characterized in that the housing grip portion is formed in a polygonal or circular shape to increase the freedom of gripping.
  3. delete
  4. In paragraph 1, A plurality of anti-slip tooth grooves formed on mutually facing surfaces of the first plunger portion and the second plunger portion along the longitudinal direction of the first plunger portion and the second plunger portion, and A cylindrical dual syringe with increased freedom of grip direction, characterized by including a tooth-catching projection protruding from the partition wall of the space portion and engaging with the anti-slip tooth groove to prevent slippage when the first plunger portion and the second plunger portion are pressurized by a relatively high-viscosity contents filled in the first filling space and the second filling space.
  5. In paragraph 4, A cylindrical dual syringe with increased freedom of grip direction, characterized by including a locking selection cap that detachably connects the tooth-locking projection to the syringe housing, wherein the tooth-locking projection is formed to select and operate an anti-slip function by the anti-slip tooth groove according to the viscosity of the contents.
  6. In paragraph 5, The above syringe housing is A selection cap groove in which the above-mentioned locking selection cap is seated, and A cylindrical dual syringe with increased freedom of grip direction, characterized by including a member hook portion protruding inward from the outer edge of the selection cap groove to fix the locking selection cap while it is forcibly inserted into the selection cap groove.
  7. In paragraph 5, A cylindrical dual syringe with increased degree of freedom in the grip direction, characterized by including an operation selection clip that is detachably coupled to the first plunger and the second plunger so that when the first plunger and the second plunger are pressed through the plunger pressurizing part, the locking selection cap is pressed and fixed to the syringe housing, or the locking selection cap is not pressed and therefore not fixed.

Description

Cylindrical dual syringe with increased freedom of grip direction The present invention relates to a dual syringe for simultaneously injecting two contents. Generally, a syringe is a device for injecting contents, and the contents filled in the syringe can be drawn in or injected as the internal pressure changes according to the movement of the plunger. A syringe is used to fill or inject only one type of contents, but to inject or mix two types of contents and to supply two types of contents simultaneously, a "dual syringe-type container" was disclosed in Korean Patent Publication No. 10-2013-0092175 (published August 20, 2013). The above-described conventional dual syringe-type container comprises: first and second containers positioned side by side on the left and right sides, each containing different contents, and equipped with first and second pumping members that perform a pumping action to discharge the contents contained therein to the outside; a container body that accommodates the first and second containers, and has a contents discharge hole formed on its upper side in communication with the first and second pumping members to allow the respective contents moving through the pumping action of the first and second pumping members to be discharged; first and second contents transfer tubes coupled to the contents discharged by the pumping action of the first and second pumping members; a tube protection cap coupled to the upper side of the container body, wrapping around the first and second contents transfer tubes; and a sealing cap coupled to the upper side of the tube protection cap, having a discharge port formed on its upper side for discharging the contents. It is configured to include a contents mixing pipe that is coupled to the lower part of the discharge port on the inner side of the above-mentioned end cap, and to which the first and second contents transfer pipes are coupled to mix and discharge the contents moving through the first and second contents transfer pipes. This conventional dual syringe-type container could easily mix and inject contents by filling the first and second containers. However, conventional dual syringe-type containers had a problem in that when a high amount of contents was filled, the discharge of the contents was delayed while the plunger was pressurized, causing the plunger to be pushed backward by internal pressure, making it impossible to discharge the desired volume of contents. In addition, conventional dual syringe-type containers have a form in which the first and second containers are attached to each other on both sides, so they are gripped only at the relatively narrow part; consequently, when the syringe needs to be rotated in various directions for injection, it is difficult to grip, which presents a problem of difficulty in injecting in various directions. FIG. 1 is a perspective view illustrating a cylindrical dual syringe with increased degrees of freedom in the grip direction according to a first embodiment of the present invention. FIG. 2 is a side cross-sectional view illustrating a cylindrical dual syringe with increased degrees of freedom in the grip direction according to the first embodiment of the present invention. FIG. 3 is a cross-sectional view of a syringe housing constituting a cylindrical dual syringe with increased degrees of freedom in the grip direction according to the first embodiment of the present invention. FIG. 4 is a side cross-sectional view illustrating a cylindrical dual syringe with increased degrees of freedom in the grip direction according to a second embodiment of the present invention. FIG. 5 is a side cross-sectional view illustrating a cylindrical dual syringe with increased degrees of freedom in the grip direction according to a second embodiment of the present invention, showing a state in which a locking selection cap is coupled to a syringe housing by the operation of a pressure plunger. Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. As illustrated in FIGS. 1 to 3, the cylindrical dual syringe (100) with increased degrees of freedom in the grip direction according to the first embodiment of the present invention can fill the syringe housing (110) with different contents and inject them simultaneously, or inject them mixed together. In the syringe housing (110), a first filling space (111) and a second filling space (112) can be partitioned by a space partition (113) to fill different contents. A first injection port (111a) may be formed in the lower part of the first filling space (111), and a second injection port (112a) may be formed in the lower part of the second filling space. Injection needles for separately injecting each of the contents may be installed in the first injection port (111a) and the second injection port (112a), or a mixing tip having a single injection port for mixing and injecting the contents to be injected by connecting
