Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a quantitative spraying device for ostomy powder. Background Technology

[0002] Stoma powder is typically in powder form, with a fine texture that is easy to apply. It is usually white or pale yellow in color and odorless or with a slight odor. The ingredients in stoma powder undergo rigorous screening and testing to ensure it is safe and harmless to the human body. For ostomy patients, the skin around the stoma is easily irritated by excrement, leading to redness, itching, and pain. Stoma powder forms a protective film on the skin surface, isolating excrement and reducing skin irritation. The absorbent properties of stoma powder can absorb moisture from the skin surface, keeping it dry and preventing skin inflammation. If the skin around the stoma is broken or ulcerated, stoma powder can promote wound healing. Its components stimulate skin cell growth and repair, accelerating the healing process. Stoma powder can also reduce wound exudate, keeping the wound clean and creating a favorable environment for healing. Stoma powder can alleviate pain and discomfort for ostomy patients. When the skin around the stoma is irritated, patients experience pain and discomfort; the use of stoma powder can relieve these symptoms and improve the patient's quality of life. Stoma powder can improve the adhesion of ostomy bags. Applying ostomy powder around the stoma before attaching the ostomy bag can help it adhere better to the skin, reducing the risk of ostomy bag falling off and leakage. The use of ostomy powder can extend the lifespan of the ostomy bag and reduce the economic burden on patients.

[0003] Existing stoma powder is sprayed onto the area around the stoma using a spraying device, then spread evenly with a cotton swab or dry gauze. After a few minutes, the powder forms a film, and any excess powder is swept away. However, the following problems arise during actual operation:

[0004] 1. When the existing device sprays the stoma powder, there is a possibility that the stoma powder may be sprayed into the stoma or outside the stoma bag area. This will waste the stoma powder and may also irritate the stoma when it is sprayed into the stoma, increasing the risk of stoma infection and blockage.

[0005] 2. Existing spraying devices control the amount of stoma powder sprayed by pressing down on the pressing element. However, in actual operation, different users press at different speeds and for different durations, so it is still impossible to control the amount of stoma powder sprayed. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this invention is to provide a quantitative spraying device for ostomy powder, which controls the amount of ostomy powder sprayed in a single application.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A stoma powder dispensing device includes a protective cover covering the patient's stoma, a mounting ring rotatably sleeved on the outside of the protective cover, a spreading mechanism fixedly sleeved on the lower part of the outer side of the mounting ring, and a storage mechanism fixedly sleeved on the upper part of the outer side of the mounting ring and extending downward into the spreading mechanism. The storage mechanism includes a storage ring body fixedly sleeved on the upper part of the outer side of the mounting ring, a cover detachably sleeved on the storage ring body, a pusher plate slidably disposed within the storage ring body along the height direction of the storage ring body, and a first return spring fixed between the cover and the pusher plate and located within the storage ring body. The lower part of the side wall of the storage ring body has several discharge holes. The storage mechanism also includes multiple discharge control components corresponding to each discharge hole. Each discharge control component includes a baffle plate slidably disposed within the storage ring body along the height direction of the storage ring body and a second return spring fixed between the baffle plate and the protective cover. The baffle plate is inserted into the discharge port and... The lower part abuts against the bottom wall of the discharge hole; the coating mechanism includes a shielding cover fixedly sleeved on the lower part of the outer side of the mounting ring, a base plate fixedly installed on the lower part of the inner side of the shielding cover, several circumferentially distributed and rotatably mounted on the bottom plate of the inner side of the shielding cover, and a metering component that slides along the height direction of the shielding cover and cooperates with the lower part of the storage ring to meter the stomatological powder; the lower part of the storage ring extends into the shielding cover after passing through the top wall of the shielding cover; the metering component includes a cover plate that abuts against the lower surface of the storage ring and slides along the height direction of the shielding cover in the shielding cover, and a third return spring fixed between the shielding cover and the cover plate; the cover plate is located below the storage ring and has several through holes along the thickness direction of the cover plate that allow the stomatological powder to pass through, and the upper surface of the cover plate is inclined downward from the outside to the inside; the bottom plate has multiple discharge channels that correspond one-to-one with the coating rollers and are located in front of the corresponding coating rollers.

[0009] More preferably, a release film is detachably sleeved on the outside of the applicator roller, a first adhesive strip is fixed to one end of the release film, and a second adhesive strip is fixed to the other end of the release film in cooperation with the first adhesive strip to achieve fixation.

[0010] More preferably, a rubber ring is fixedly provided around the top of the cover.

[0011] More preferably, an angle indicator line is also provided at the outer edge of the top of the cover.

[0012] More preferably, the removable cover below the shield is equipped with a sealing cover.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this invention, the stoma powder stored in the storage ring passes through the through hole, the shield, and the discharge channel in sequence, and then falls around the patient's wound. Under the shielding of the shield and the installation ring, the stoma powder can only fall into the designated area and will not fall into the stoma or outside the range of the stoma bag. On the one hand, this can avoid the waste of stoma powder as much as possible, and on the other hand, it can also avoid the irritation to the stoma when the stoma powder is sprayed into the stoma, thereby reducing the risk of interference and blockage caused by the stoma powder entering the stoma.

[0015] 2. When in use, this utility model uses an inverted method to ensure that the amount of ostomy powder taken out from the storage ring at one time is kept constant (i.e., it fills the closed space formed by the cover, shield and outer wall of the storage ring). This prevents different amounts of ostomy powder from being taken out each time due to different pressing speeds and pressing times of different users, so as to further precisely control the amount of ostomy powder sprayed.
