Technical Field

[0001] The utility model relates to the technical field of medical supplies, and in particular to a multifunctional mask capable of assisting in cooling down. Background Art

[0002] Oral and maxillofacial surgery patients need local ice compresses for analgesia and hemostasis. Cold compress masks are usually used clinically to free the hands. Most existing cold compress masks are fixed with ear hooks or Velcro, and the inner layer of the mask is provided with a plug-in cooling material. However, the cooling material of this type of mask is easy to shift and fall off during use, and cannot form a 3D fit and coverage for the mandibular angle and the front of the ear. In addition, the cooling coverage area of ​​the plug-in cooling mask is not accurate, and it will inevitably involve areas that do not need cooling, and it is impossible to achieve precise positioning and cooling of the surgical site.

[0004] A multifunctional mask capable of assisting in cooling down comprises a mask body that fits the contour of a human face, wherein the mask body is provided with a first non-woven fabric layer, a meltblown fabric layer and a second non-woven fabric layer in sequence from outside to inside, and the second non-woven fabric layer is provided with a silk cotton sheet and a cooling functional part corresponding to lips and cheeks of the human body, respectively, and the cooling functional part comprises a cooling cavity layer, a hydrocolloid dressing layer and a first release paper layer that are arranged in sequence from outside to inside, and the cooling cavity layer is divided with incisors as the central axis and is provided with four adjacent and independent cavity bags that cover the left side, the left lower jaw, the right side and the right lower jaw respectively, and each cavity bag is provided with a peelable seal that separates the interior of the cavity bag into a first chamber and a second chamber, and the first chamber and the second chamber are respectively filled with sodium carbonate powder and ammonium nitrate solution.

[0005] A further technical solution is that the cavity bag is made of thermoplastic polyurethane elastomer material.

[0006] A further technical solution is that gaps are provided between adjacent edges of the cavity bag.

[0007] A further technical solution is that mint and borneol components are added to the hydrocolloid dressing layer.

[0008] A further technical solution is: the silk cotton piece is soaked with chlortetracycline eye ointment, and the side of the silk cotton piece close to the lips is bonded and covered with a second release paper layer.

[0009] A further technical solution is: a temperature sensing coating is provided on the non-woven fabric layer located on the outermost side of the mask body, and the temperature sensing coating adopts one or more of triarylmethanephthalide type color-changing powder or indolinephthalide type color-changing powder.

[0010] A further technical solution is: a shaping strip that fits the bridge of the nose is provided on the first non-woven fabric layer.

[0011] Beneficial effects of the utility model:

[0012] The mask body of the utility model fits the contour of a human face, and comprises a first non-woven fabric layer, a meltblown fabric layer and a second non-woven fabric layer, wherein the second non-woven fabric layer is provided with a cooling cavity layer for achieving cold compress analgesia and a hydrocolloid dressing layer for being adhered and fixed on the human face.

[0013] The cooling chamber layer is equipped with four chamber bags corresponding to the left side, left mandible, right side, and right mandible of the human body, which accurately divides the target cooling area and reduces unnecessary cooling of the non-surgical side.

[0026] A multifunctional mask that can assist in cooling down, such as Figure 1-4As shown, it includes a mask body 1 that fits the facial contour of a human body. The mask body 1 is sequentially provided with a first non-woven fabric layer 2, a meltblown fabric layer 3 and a second non-woven fabric layer 4 from the outside to the inside. The second non-woven fabric layer 4 is respectively provided with a silk cotton sheet 5 and a cooling functional part 6 corresponding to the lips and cheeks of the human body. The cooling functional part 6 includes a cooling cavity layer 7, a hydrocolloid dressing layer 12 and a first release paper layer 13 sequentially arranged from the outside to the inside. The cooling cavity layer 7 is divided into four adjacent and independent cavity bags 8 covering the left side, the left lower jaw, the right side and the right lower jaw respectively with the incisors as the central axis. A peelable seal 9 is provided inside each cavity bag 8. The peelable seal 9 divides the interior of the cavity bag 8 into a first chamber 10 and a second chamber 11. The first chamber 10 and the second chamber 11 are respectively filled with sodium carbonate powder and ammonium nitrate solution. When the target area needs to be cooled, the user needs to tear or squeeze the peelable seal 9 between the first chamber 10 and the second chamber 11 of the corresponding cavity bag 8, so that the sodium carbonate powder and ammonium nitrate solution filled in the two chambers can be quickly cooled within 2 seconds. After tearing off the first release paper layer 13 on the innermost side of the mask body 1, the mask body 1 is pasted on the patient's cheek and mandible through the hydrocolloid dressing layer 12, so that the mask can be worn and achieve an immediate cooling effect.

[0027] The four cavity bags 8 are all made of thermoplastic polyurethane elastomer material (TPU), which is wear-resistant, cold-resistant and chemical-resistant. The cavity bags 8 and the second non-woven fabric layer 4 are bonded with medical viscose or environmentally friendly adhesive.

[0028] In order to facilitate the opening of the peelable seal 9 in the corresponding cavity, gaps 16 are provided between adjacent edges of the cavity bag 8, so that adjacent cavity bags 8 are not completely connected or not connected, which is convenient for the user to control the opening of the peelable seal 9 in the designated cavity bag 8, and achieve accurate cooling of the patient's surgical site. The peelable seal 9 used in this embodiment is a prior art, made of polypropylene or modified polypropylene material, and made by a multi-layer co-extrusion film process. Before use, the peelable seal 9 separates the cavity bag 8 into a first chamber 10 and a second chamber 11 that are not connected to each other. When in use, the peelable seal 9 is opened by squeezing hard to connect the first chamber 10 and the second chamber 11.

[0029] The dressing in the hydrocolloid dressing layer 12 core is covered on the postoperative part of the patient. The dressing is sticky and can be bonded to the patient's facial skin to fix the mask. It not only has a good fixing effect, reduces the pressure on the auricle and bony protrusions, increases comfort, but also helps the patient's postoperative wound healing. The backing of the hydrocolloid dressing layer 12 is bonded to the cavity bag 8 with medical adhesive, and the core of the hydrocolloid dressing layer 12 is bonded to the first release paper layer 13. Preferably, mint and borneol components are added to the core of the hydrocolloid dressing layer 12 to assist in cooling when in use, thereby increasing the comfort of postoperative patients.

[0030] In order to reduce friction and irritation to the sensitive part of the lips, a silk cotton sheet 5 is arranged at the position of the second non-woven fabric layer 4 corresponding to the lips, which is soft, skin-friendly, moisture-absorbing and breathable. Specifically, the silk cotton sheet 5 and the second non-woven fabric layer 4 are fixed by medical viscose bonding or edge stitching.

[0031] Preferably, the silk cotton sheet 5 is soaked with chlortetracycline eye ointment, and the side of the silk cotton sheet 5 close to the lips is bonded and covered with a second release paper layer 14. The chlortetracycline eye ointment on the silk cotton sheet 5 is applied to the lips of the patient to prevent angular cheilitis after oral and maxillofacial surgery and relieve the patient's postoperative discomfort.

[0032] The first release paper layer 13 and the second release paper layer 14 are made of silicone resin treated protective paper to protect the cooling function part 6 from being contaminated when not in use, and are removed and discarded when in use. The shapes and sizes of the first release paper layer 13 and the second release paper layer 14 are respectively adapted to the cooling chamber layer 7 and the silk cotton sheet 5.

[0033] The first non-woven fabric layer 2 is provided with a temperature-sensitive coating, and the temperature-sensitive coating adopts an organic low-temperature reversible thermochromic material as a coating, and specifically, the coating adopts one or more of triarylmethanephthalide type color-changing powder or indolinephthalide type color-changing powder. If the temperature of the mask does not reach the cold compress effect or the temperature is too low after a period of use, the temperature-sensitive coating will change color, which is convenient for medical staff or users to monitor in real time so as to replace it in time. Preferably, the first non-woven fabric layer 2 is also provided with a shaping strip 15 that fits the bridge of the nose, which is ergonomically designed to make the mask better cover the face.

[0034] The meltblown cloth layer 3 has good filterability and air permeability, and can filter droplets, particles or bacteria to protect the patient's surgical site.

[0035] The second non-woven fabric layer 4 is made of skin-friendly non-woven fabric, which reduces irritation to the skin of other contact areas of the patient and can absorb moisture to improve the comfort of the patient.

[0036] The outer edges of the first non-woven fabric layer 2, the meltblown fabric layer 3 and the second non-woven fabric layer 4 are pressed and connected in sequence from top to bottom by a press. In other embodiments, a medical viscose bonding fixation method can also be adopted.
