Description

Technical Field

[0001] This invention relates to the field of packaging sealing, and in particular to a sealing device for medical dressing packaging. Background Technology

[0002] Medical dressings are typically packaged individually. After production, the dressings are divided into individual pieces using a feeding device and placed between two long plastic films. A hot press then seals the dressing by pressing the plastic films together around its perimeter. Subsequent cutting completes the packaging. If multiple dressings are packaged in the same container, and only one is needed, the unused dressing will be exposed to air and become contaminated. Therefore, current medical dressing packaging and sealing methods can only package one dressing at a time, resulting in low efficiency. Furthermore, the individual packaging requires more packaging material, leading to higher costs. Since medical dressings are applied to patient wounds, high hygiene standards are required. The dressings are easily contaminated with bacteria during packaging, and using a sterile environment significantly increases packaging costs. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention discloses a sealing device for medical dressing packaging. This invention involves applying alcohol to the left, right, front, and back of four dressings, ensuring that the openings face different directions after a single heat-press packaging process. By cutting the packaging with scissors along different edges, one dressing can be removed without affecting the sealing of the other dressings. Four dressings can be packaged at once, resulting in high packaging efficiency. Only five plastic films are needed to seal four dressings, leading to high material utilization and low packaging costs. The alcohol remaining in the packaged dressings disinfects them and prevents contamination during the packaging process.

[0004] To achieve the aforementioned objective, the present invention employs the following technical solution:

[0005] A sealing device for medical dressing packaging includes a base plate with five plastic films on the base plate, a heat-pressing mechanism on the right end of the base plate, and an alcohol application mechanism on the left side of the heat-pressing mechanism.

A second sponge body is fixed in the middle of the second hollow plate, and a through hole is opened at the connection between the second hollow plate and the second sponge body. On the two symmetrical telescopic rods, between the third and fourth plastic films from bottom to top... Two sets of telescopic rods are symmetrically connected and fixed with three hollow plates, each with an internal hollow core. The front sides of the two third hollow plates are connected and fixed with a fourth hollow plate, each with an internal hollow core. A third sponge is fixed in the middle of the fourth hollow plate.

[0024] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0025] Combined with appendix Figures 1-8 A sealing device for medical dressing packaging includes a base plate 1, on which five plastic films 4 are provided. A heat-pressing mechanism is provided at the right end of the base plate 1, and an alcohol application mechanism is provided at the left side of the heat-pressing mechanism.

[0026] Support legs 101 are fixed at the four corners of the lower surface of the base plate 1. Five sets of columns 102 are fixed symmetrically and equidistantly on the upper surface of the base plate 1. A rotating shaft 103 is rotatably connected between two symmetrical columns 102.

The three partitions 104 are equidistant from bottom to top. The partitions 104 can support the plastic film 4. The upper surface of the base plate 1 and the upper surface of the partitions 104 are smooth to make the plastic film 4 slide more smoothly on them.

[0028] A plastic film 4 is slidably connected to the left side of the rotating shaft 103. The lower surface of the plastic film 4 is slidably connected to the upper surface of the base plate 1 and the three partition plates 104. Dressings 401 are equidistantly arranged on the plastic film 4. The left end of the plastic film 4 is connected to the external material roller. The dressings 401 are placed on the plastic film 4 by the external material feeding device, and the upper and lower corresponding dressings 401 overlap each other.

[0029] The hot pressing mechanism includes a movable plate 3, on which ear plates 306 are symmetrically fixed. A first electric telescopic rod 303 is fixed on the upper surface of the ear plates 306. A pressure plate 304 is fixed at the upper end of the first electric telescopic rod 303. An alcohol tank 305 is fixed below the pressure plate 304. A hot pressing plate 301 is fixed below the alcohol tank 305 and above the movable plate 3. A square hole 302 is opened in the middle of the lower surface of the upper hot pressing plate 301. A second electric telescopic rod 307 is fixed in the middle of the left side of the movable plate 3. The left end of the second electric telescopic rod 307 is fixed in the middle of the right side of the base plate 1.

[0030] The alcohol box 305 is hollow inside, and a third rubber hose 308 is connected to the upper surface of the alcohol box 305. The outer end of the third rubber hose 308 is connected to an external alcohol or disinfectant supply device.

[0031] The alcohol application mechanism includes two mounting plates 2, which are fixed to the front and rear ends of the left side of the movable plate 3, respectively. Telescopic rods 201 are symmetrically fixed on the mounting plates 2. The telescopic rods 201 are hollow inside. A first rubber hose 212 is connected to the top of the telescopic rods 201. A second rubber hose 213 is connected to the top of the first rubber hose 212. The right end of the second rubber hose 213 is connected to the alcohol tank 305.

[0032] On the right side, two symmetrical telescopic rods 201 are connected and fixed between the two lowest plastic films 4, with a hollow first plate 202. A first sponge 203 is fixed in the middle of the first hollow plate 202, and a through hole is provided at the connection between the first hollow plate 202 and the first sponge 203. On the left side, two symmetrical telescopic rods 201 are connected and fixed between the second and third plastic films 4 from bottom to top, with a hollow second plate 204. A second sponge 205 is fixed in the middle of the second hollow plate 204, and a through hole is provided at the connection between the second hollow plate 204 and the second sponge 205. On the left side, two symmetrical telescopic rods 201 are connected and fixed between the third and fourth plastic films 4 from bottom to top. A third hollow plate 206, which is hollow inside, is symmetrically connected and fixed to the right. A fourth hollow plate 207, which is hollow inside, is connected and fixed to the front side of the two third hollow plates 206. A third sponge 208 is fixed to the middle of the fourth hollow plate 207. A through hole is opened at the connection between the fourth hollow plate 207 and the third sponge 208. A fifth hollow plate 209, which is hollow inside, is symmetrically connected and fixed to the left and right sides of the two sets of telescopic rods 201 located between the two uppermost plastic films 4. A sixth hollow plate 210, which is hollow inside, is connected and fixed to the rear side of the two fifth hollow plates 209. A fourth sponge 211 is fixed to the middle of the sixth hollow plate 210. A through hole is opened at the connection between the fourth sponge 211 and the sixth hollow plate 210.

[0033] The aforementioned sealing device for medical dressing packaging, during use, allows external alcohol to enter the hollow spaces within the first hollow plate 202, second hollow plate 204, second hollow plate 206, third hollow plate 207, fourth hollow plate 209, and fifth hollow plate 210 through the third rubber hose 308, alcohol tank 305, first rubber hose 213, first rubber hose 212, and telescopic rod 201. Because the external alcohol is positioned higher, the alcohol within the first hollow plate 202, second hollow plate 204, third hollow plate 206, fourth hollow plate 207, fifth hollow plate 209, and sixth hollow plate 210 will also pass through the first hollow plate 202, second hollow plate 204, fourth hollow plate 206, and sixth hollow plate 210. 07. The holes opened on the sixth hollow plate 210 are used to wet the first sponge 203, the second sponge 205, the fourth sponge 211, and the third sponge 208. The five plastic films 4 slide on the upper surface of the base plate 1 and the upper surface of the partition plate 104, respectively, around the left side of the rotating shaft 103. The right end of the plastic film 4 is placed above the hot press plate 301 by manual pulling. The left end of the plastic film 4 is connected to the external material roller and can be automatically discharged with the traction force. The dressing 401 is placed at the same position on the four plastic films 4 below by the external material feeding device. When the telescopic rod 201 is shortened, it can drive the first sponge 203, the second sponge 205, the fourth sponge 211, and the third sponge 208 to move downward, so that the upper and lower positions coincide. Alcohol is applied to the four dressings 401 from bottom to top, on the left, right, front, and back sides respectively. When the first electric telescopic rod 303 is shortened, the two heat-pressing plates 301 are pressed together by the pressure plate 304. The heat-pressing plates 301 press the five plastic films 4 and the dressings 401 between them together. Since alcohol is applied to the plastic films 4 in sequence on the front, back, left, and right sides of the four dressings 401, the areas where alcohol is applied will not be pressed together due to evaporation and heat absorption when the heat-pressing plates 301 heat-press the plastic films 4. Therefore, after the four dressings 401 are heat-pressed and packaged by the five plastic films 4, they can be cut to form a square assembly. When in use, the four sides of the square assembly can be torn open sequentially to remove the dressing. One dressing 401 is dispensed, while the other dressings 401 remain sealed. Upon initial startup, the right end of the plastic film 4 can be manually pulled and placed on the heat press plate 301. Simultaneously, the telescopic rod 201 and the first electric telescopic rod 303 shorten, applying alcohol to the plastic film 4 at the edge of the group of dressings 401 closest to the left side of the heat press plate 301. At the same time, the two heat press plates 301 press the plastic film 4 tightly. At this point, no dressing 401 is placed between the upper plastic films 4 on the heat press plate 301. Then, the second electric telescopic rod 307 extends the distance between the two dressings 401, causing the plastic film 4 to move a distance to the right on the upper surface of the base plate 1 and the partition plate 104. Afterward, the first electric telescopic rod 303 extends, separating the two heat press plates 301.The extension of telescopic rod 201 separates the first sponge body 203, the second sponge body 205, the fourth sponge body 211, and the third sponge body 208 from the dressing 401. The retraction of the second electric telescopic rod 307 causes the moving plate 3 to move to the left and return to its original position. Since the heat-pressing plate 301 has separated from the plastic film 4, the plastic film 4 remains in its original position when the moving plate 3 moves to the left. When the moving plate 3 moves to the left and returns to its original position, the alcohol-coated plastic film 4 and the dressing 401 are positioned directly below the square hole 302. The retraction of the first electric telescopic rod 303 heat-presses the five plastic films 4, sealing the plastic film 4. Repeating the above process continuously pulls the plastic film 4 and heat-presses and seals it.

[0034] The parts of this invention not described in detail are prior art. Although the invention has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of the invention. However, those skilled in the art should understand that various changes in form and detail can be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the invention.
