Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, in particular to a hydrocolloid dressing surface gel coating device. Background Art

[0002] A hydrogel is a gel that uses water as its dispersion medium. Hydrogels are formed by introducing a number of hydrophobic groups and hydrophilic residues into a water-soluble polymer with a network structure. The hydrophilic residues bind to water molecules, thereby connecting them within the network, while the hydrophobic residues swell when exposed to water. A cross-linked polymer with a polymer network system, hydrogels are soft, can maintain a certain shape, and can absorb large amounts of water.

[0003] As a highly water-absorbing and water-retaining material, hydrogel is widely used in the medical field, such as fever-reducing patches and analgesic patches. Nowadays, the gel on the surface of the hydrocolloid dressing in the hydrogel is coated on its surface by a coating device, which requires the use of a coating device. For example, the patent website discloses a hydrocolloid dressing surface gel coating device (Announcement No.: CN210876075U). The amount of gel required by this device is controlled by pressing the pull handle, but there is no scale on the pull handle, and the amount of gel pushed out depends entirely on the user's experience, resulting in the device being unsuitable for novices and the problem that there is a large error in the amount pushed out. Therefore, those skilled in the art have proposed a hydrocolloid dressing surface gel coating device. Utility Model Content

[0030] Unscrew the upper cover 2 from the gel filling cylinder 1, fill the gel filling cylinder 1 with gel through the port of the gel filling cylinder 1, and then screw the upper cover 2 back on the threaded portion of the port of the gel filling cylinder 1. Then, rotate the knob 8 to drive the screw 6 to rotate. The rotating screw 6 moves toward the inside of the gel filling cylinder 1 through the threaded cylinder 5, thereby driving the sealing ring 7 to move in the gel filling cylinder 1. The moving sealing ring 7 can be used to push the gel in the gel filling cylinder 1 into the coating head 10, and then evenly spread it on the surface of the hydrocolloid dressing by the coating mesh 4.

[0032] Two card slots 11 are opened on the front surface of the coating head 10, each card member 13 is arranged inside the corresponding card slot 11 and is fixedly connected to the annular plate 3, each slot 14 is opened on the side of the corresponding card member 13, each fixing seat 15 is installed on the side of the coating head 10 and is on one side of the corresponding card member 13, each cavity 16 is opened inside the corresponding fixing seat 15, each limit plate 17 is slidably set in the corresponding cavity 16, each plug-in 18 is set in the corresponding slot 14 and fixedly connected to the adjacent limit plate 17, each pull rod 19 is installed at the center of the other side of the corresponding limit plate 17 and extends to the outside of the fixing seat 15, and each spring 20 is sleeved on the corresponding pull rod 19 and is in the cavity 16;

[0033] When the coating screen 4 needs to be replaced, pull the two pull rods 19 outward to drive each plug-in 18 to move out of the insertion slot 14 while compressing the spring 20 through the limit plate 17 to release the fixation of the annular plate 3. Then the coating screen 4 is connected and removed from the coating head 10. Then the two clips 13 on the outer annular plate 3 of the new coating screen 4 are inserted into the two card slots 11. When it is fully inserted, the slot 14 on each clip 13 is aligned with the plug-in 18. Then release the two pull rods 19 to let the two springs 20 rebound and drive the two plug-ins 18 to be inserted into the aligned slots 14, thereby fixing the coating screen 4 on the coating head 10. The replacement is completed without the need for professional tools, which is convenient for users to operate.
