Description

Multipurpose medical powder spraying device {Spray for multipurpose medical powder}

The present invention relates to a multipurpose medical powder spraying device, and more particularly, by replacing and combining a plurality of nozzles connected to each other with injection tubes having different materials and lengths as needed, so that medical powder can be sprayed to suit the purpose, The combination of each component is made by screwing or fitting, etc., and the medical powder that can be sprayed by this spraying device has no limitations such as hemostatic agents, anti-adhesion agents, wound dressings, etc., so it can be applied to various surgical operations. It relates to a multi-purpose medical powder spraying device with an expanded scope.

Surgical operation refers to a medical practice in which a person's skin or mucous membrane is incised and treated inside by using a medical instrument. Depending on the severity of these surgical operations, there are cases where the patient's life is endangered, and there is a risk of various unexpected accidents such as bleeding and adhesions. In addition, for the ease of use and management, it is often manufactured in powder form.

For example, bleeding means blood comes out of the blood vessels, and the blood vessels that make up the whole body circulate the blood in the blood vessels throughout the body by the pressure of the heart. It means blood is leaking out of the wound.

Hemostasis is a process to stop bleeding and refers to maintaining blood in damaged blood vessels. When hemostasis occurs, it is most important to quickly stop the bleeding site by suturing or compressing the wound with a hemostatic agent, bandage, or dressing. In particular, in recent years, the demand for hemostatic agents having excellent hemostatic properties while being excellent in human-friendly biocompatibility is increasing. In order to respond to this, hemostatic agents are being developed using non-toxic, biocompatible polymers as the main material, and to meet the various demands of the market with improved hemostatic effects.

Adhesion refers to a phenomenon in which blood coagulates in the healing process after tissue is damaged by bleeding, wounds, friction, etc. due to surgery or other reasons, and abnormal bonding with surrounding tissues occurs during the clotting process. Therefore, it is common to use an anti-adhesion agent to prevent this.

In addition, the wound refers to the destruction of the continuity of human tissue by external pressure or other factors. There is a risk of infection or inflammation due to exposure to the external environment during wound treatment, and in order to prevent this, drugs such as wound dressing are manufactured and used.

However, even if a hemostatic agent, an anti-adhesion agent, and a wound dressing that meet these purposes are developed, it is also essential to apply or administer them in an appropriate amount at an appropriate location. For example, the material of the nozzle or tube for applying the drug may be different for various purposes such as surgical operation, procedure, and laparoscopy, and a different length may be required. Therefore, it is necessary to replace the nozzle portion for applying such a drug from time to time to suit the use as necessary, and such replacement is required to be made quickly and simply.

However, the existing drug application mechanism is generally developed and manufactured in a shape in which the nozzle portion is integrally coupled to the chemical application mechanism, so it is not possible to respond to these demands.

As an example, Korean Patent Registration No. 10-1397600 discloses a spraying device capable of spraying powder by forming a nozzle portion capable of spraying various powdered drugs, such as a hemostatic agent, integrally with the spraying device. However, the configuration corresponding to the pipe is not connected to the nozzle part, it has only a relatively short length, and since the nozzle part and the injection device are integrally formed, it is not recognized that the configuration can be replaced if necessary. , it cannot be applied at all in cases such as laparoscopy.

Therefore, the development of a variety of excellent powder drugs used in surgery, such as hemostatic agents, at the same time as the development of a device capable of properly applying or spraying it is also required.
