DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fine fiber material discharging apparatus for uniformly discharging a fine fiber material, in particular, an absorbable local hemostatic agent (collagen fine fiber).

[0002]

2. Description of the Related Art As a general discharge device, a pressurized discharge device or a spray type device is used.

[0003]

SUMMARY OF THE INVENTION The present material is an elastic cotton-like material having a short fiber length, which is composed of a microfibrous protein. This property is easily entangled, and when compressed, the cotton-like material is crushed and solidified. For this reason, the above-described pressurized discharger and misting type were clogged and could not be used. An object of the present invention is to provide a microfibrous material discharging apparatus which does not generate a state of hardening before the material is stored until discharged.

[0004]

The microfiber material discharging apparatus according to the present invention has a container, a pressurized gas supply, and a connecting part. The container has a spherical inner wall surface.
And a main body, a lid detachable from the main body, a mounting port, and a discharge port. The pressurized gas supply unit includes a pressurized gas source, a gas supplier that regulates and supplies gas from the pressurized gas source,
It has an outlet. The connecting portion has an outlet portion connected to the outlet of the pressurized gas supply portion at one end, and an introduction portion connected to the mounting port of the container portion at the other end. I have. Then, a nozzle portion is formed at the end of the mounting port or the introduction portion that continues into the container portion so as to open tangentially to the spherical surface . The discharge port is located on the same axis as the nozzle section, and the diameter of the discharge port is larger than the diameter of the nozzle section.

[0005] sphere Katachimen is divided into upper and lower, middle portion that has become a cylindrical surface. The spherical surface located on the line connecting the nozzle portion and the discharge port is cut away to form a passage having a cross-sectional shape whose open side is widened. The connection has a separable chamber in the middle for loading the filter. The main body of the container is made of a transparent material. The microfiber material is a collagen microfiber.

[0006]

The microfibrous material is placed in the container, and a pressurized gas source is set in the gas supply. In the case where the pressurized gas source is a cylinder in which the pressure gas is sealed with a sealing plate, the sealing plate is opened by setting it in the gas supply device, and the gas supply is ready. Here, the pressurized gas supply unit is connected to the container unit via the connection unit. Thus, the nozzle portion and the discharge port are arranged in a straight line in the container portion.

When discharging the microfiber material, the discharge port is directed in the direction in which the microfiber material is supplied, and the lever of the gas supply device is operated. The gas discharged from the pressurized gas source flows into the gas supply device, the pressure is adjusted, and flows into the container portion from the nozzle portion through the connecting portion. The gas flow goes straight and flows out of the discharge port to the outside. The cross-sectional area of the gas jet flowing from the nozzle portion to the discharge port slightly increases at the portion entering the discharge port immediately after leaving the nozzle portion, but since the diameter of the discharge port is larger than the diameter of the nozzle portion, The jet stream does not circulate in the container.

[0008] The jet flow of the gas generates a negative pressure in the container portion, and the gas in contact with the outer peripheral portion of the gas flux in the container portion starts to move by dragging, thereby causing commutation in the container portion. Therefore, the microfiber material circulates in the container part along the commutation, so that the microfiber materials do not solidify, and the microfiber material approaching the jet flow is dragged by the negative pressure into the jet flow. The liquid is ejected from the discharge port and rushes to the surface to be supplied. When the surface to be supplied is a surface that requires hemostasis, the microfibrous material adheres to the surface and exerts a hemostatic action.

When the inner wall surface of the container portion is a spherical surface, or the spherical surface is divided into an upper portion and a lower portion, and an intermediate portion is a cylindrical surface, and the nozzle portion is tangentially open to the spherical surface, The circulating flow generated in the section becomes a single rotating flow, which works well for stirring the microfiber material. When the spherical surface located on the line connecting the nozzle portion and the discharge port is cut out to form a passage having a cross-sectional shape in which the open side is widened, it is extremely good to take in the microfibrous material into the jet stream. Become.

It is very preferable in terms of hygiene that the connecting portion is provided with a separable chamber for inserting a filter in the intermediate portion, thereby preventing bacteria and dust from being mixed.

When the main body of the container is made of a transparent material, the used amount and the remaining amount of the fine fiber material can be confirmed from the outside. When the microfiber material is a microfiber of collagen,
It is possible to discharge uniformly and without clogging, which is difficult to discharge with a normal pressure type discharger or spraying device.
