Technical Field [0001] The present invention relates to a method for manufacturing a hybrid medical shoe,

The present invention relates to a method for manufacturing a hybrid medical shoe, and more particularly, to a method for providing a medical shoe having an inner skin and a toe cap to protect a foot.

Generally, doctors work long hours in hospitals, do medical services, perform procedures and perform operations. In order to minimize work fatigue, most doctors often wear shoes with shoes that can be easily worn in the hospital, in addition to shoes that are worn outside. The doctors also wear the shoes that are worn only in the hospital for the cleanliness of the hospital.

However, most of these shoes are general shoes sold on the market, and they are unsuitable for hospitals requiring cleanliness because they are shoes that do not have antibacterial and sterilizing functions. In particular, there is a problem in that it is not suitable for wearing in an operating room which must be maintained in an aseptic state.

In addition, there are many medical devices connected electrically in the operating room. When a general shoe made of a material which can not be charged is used as a slippery, there is a problem that a safety accident is caused by static electricity in the operating room.

Accordingly, there is a need to develop a technique of a medical shoe which can reduce the fatigue burdened by a doctor, prevent slippage and safety accidents, and combine antimicrobial and sterilizing functions at the same time.

The present invention relates to a method for manufacturing a hybrid medical shoe, which is lightweight while protecting feet from the external environment, and an antibacterial and sterilizing machine for producing the combined medical shoe.

The medical shoe according to the present invention is formed so as to be suitable for use by a physician working in a hospital and is made of a light material so as to reduce fatigue imposed on the wearer's foot and is used in hospitals having antibacterial and sterilizing functions It is a shoe which is composed of a material to be charged and equipped with a toe cap. It is a shoe that can prevent a safety accident.

Also, the medical shoe of the present invention can be used by a patient who is uncomfortable in the hospital. Particularly, the medical shoe of the present invention is light and durable and has excellent foot protection function for a wearer who is injured on the legs and feet.

1 is a flowchart of a method for manufacturing a hybrid medical shoe according to the present invention.

As shown in FIG. 1, the present invention includes an inserting step (S10) of inserting a last into the inside of the inner tube, a toe cap fixing step (S20) of fixing a toe cap to the inner surface of the inner tube, A synthetic resin injection step S40 for injecting synthetic resin into the injection mold, an encapsulation step S50 for drying the synthetic resin to form an envelope, and a trimming step S60 for trimming the envelope. And the like.

Hereinafter, each step according to the present invention will be described in detail.

In the hybrid medical shoe manufacturing method according to the present invention, the inserting step (S10) is performed first.

FIG. 2 is a perspective view showing a state where the last 110 is inserted into the inner skin 120, and after the insertion step is completed, it may be formed as shown in FIG.

The inserting step S10 is a step of inserting the last 110 into the already formed shoe-like inner skin 120. Here, the last 110 is a frame or a model for contouring when manufacturing shoes, and is generally used as a tool for making shoes. And the last 110 is a tool made by foot size.

The inner skin 120 is also manufactured in advance according to the size of the foot, and the inner skin 120 according to the present invention is a portion directly contacting the wearer's foot. As an embodiment of the present invention, the endothelium 120 may be made of synthetic resin. The type of the synthetic resin constituting the inner skin 120 is not limited, and any synthetic resin having flexibility and excellent protection against the foot can be used. Also, the endothelium is composed of materials that are charged.

After the inserting step S10, the toe-cap fixing step S20 is performed. 3 is a perspective view showing a state in which the toe cap 130 is installed on the inner skin 120. Referring to FIG. 3, the toe cap fixing step S20 is a step of fixing the toe cap 130 to the front surface of the inner skin 120. The toe cap 130 has a certain strength, such as plastic, and is fixedly installed at a position where the toe can be positioned on the inner skin 120. The toe cap 130 can prevent a dangerous object from falling on the shoe so that the toe or the forefoot region is injured.

Accordingly, the toe cap 130 according to the present invention can be positioned and fixed in front of the inner skin 120 where the toe can be positioned. And is fixed to the surface of the inner skin 120.

A shape in which the toe cap 130 is installed and fixed on the front surface of the inner skin 120 can be represented as shown in FIG.

After the toe-cap fixing step S20, an inner-skin-laying step S30 for advancing the inner skin 120 provided with the toe cap 130 to the injection mold proceeds.

4 shows a state in which the inner film 120 is disposed on the injection mold. Referring to FIG. 4, the endothelial deposition step S30 will be described.

The hybrid material shoe according to the present invention includes an outer skin formed by wrapping the inner skin 120 and the toe cap 130 from the outside in addition to the inner skin 120 having the toe cap 130 installed therein. Therefore, the endothelial deposition step S30 is a step for forming the outer shell. Injection mold is a molding frame formed so that it can see shoes. In the endothelial deposition step S30, the endothelium 120 is placed in the lower mold of the injection mold as shown in Fig. At this time, as described above, the inner cap 120 is fixedly installed with the toe cap 130, and the inner cap 120 is disposed in the lower mold of the injection mold with the last 110 inserted therein.

When the inner film 120 is disposed on the lower mold of the injection mold, the upper mold of the injection mold can be brought into close contact with the upper mold and sealed.

After the endothelial deposition step S30, a synthetic resin injection step S40 is performed. The synthetic resin injection step S40 is a step of injecting synthetic resin into the inner space of the injection mold. The injection mold has an injection port for injecting synthetic resin, and synthetic resin can be injected into the injection port. The synthetic resin injection step may be performed until the inside of the injection mold is filled with the outer surface of the inner pipe 120 disposed inside the injection mold.

The injection mold may be provided with a plurality of injection molds corresponding to shoe sizes to be manufactured.

When the inside of the injection mold is filled with the synthetic resin, the synthetic resin is dried to form a shoe-shaped envelope (S50).

5 is a perspective view showing a medical shoe in which a skin 140 is formed.

5, the envelope forming step S50 may be performed by drying and curing the liquid synthetic resin injected to form the envelope 140, thereby forming the envelope 140 on the surface of the endothelium and the toe cap To form the envelope 140 having a certain shape.

The outer cover 140 is made of a synthetic resin having a small specific gravity, and can provide light shoes with excellent durability. Also, the outer cover 140 may be configured to include an antibacterial substance. The outer cover 140 may be made of a synthetic resin which is easy to clean, and which is prevented from being deformed by washing. The lower surface of the envelope 140 may be formed by attaching a slip-proof projection or an anti-slip rubber.

The envelope 140 may also be formed of polyurethane, according to one embodiment of the present invention. The envelope 140 may also be formed of various synthetic resins other than polyurethane.

Next, as a final step of the method for manufacturing a medical shoe according to the present invention, a trimming step (S60) is performed. The trimming step S60 is a step of smoothing the contour of the outer cover 140 manufactured by drying and curing the liquid synthetic resin. More specifically, when the synthetic resin is injected into the injection mold in the synthetic resin injection step (S40), there may occur a case where the synthetic resin leaks into a gap that can be finely formed in the injection mold. If the synthetic resin is cured in this state, a non-clean outer covering 140 can be formed. Accordingly, the trimming step S60 is performed in order to manufacture an externally clean shoe by cutting and scraping unnecessary portions of the surface of the envelope 140 when the envelope 140 is formed after the synthetic resin is cured.

According to the method of manufacturing a medical shoe according to the present invention, when a finished product having a covering 140 is formed by wrapping the surface of an inner skin provided with a toe cap as shown in FIG. 5, the last 110 inserted in the inner skin 120 is removed .

According to one embodiment of the present invention, the toe cap 130 may be formed of a plastic material having a certain strength, or may be formed of a metal material. If the toe cap 130 is formed of a metal material, a metal material having a small specific gravity can be used to make the weight of the shoe as light as possible.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the claims of the invention to be described below may be better understood. It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
