Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a postoperative neck dressing. Background Art

[0002] Currently, the wound dressing after thyroidectomy is typically composed of two pieces of gauze, one inside and one outside, which do not fit perfectly. Common bandaging methods currently rely on separately configured paper tape or cloth tape. The fixable area on the dressing or gauze is small. When using tape to secure the gauze, paper tape, which has good breathability, often has poor adhesion. When the patient's neck moves, the paper tape easily curls, loses its adhesion, and becomes loose, which does not last long. Strongly sticky cloth tape can easily cause tension blisters or skin allergies. Dressings or gauze without a fixed area are prone to loosening, leading to incision contamination or unnecessary wound dressing changes.

[0003] At the same time, when the patient's neck moves, gaps or dislocations can easily appear in the gauze. When bleeding occurs from an incision, it will generally soak through the lower gauze first and then appear on the upper gauze. Since incisional bleeding usually oozes out slowly, when blood appears on the upper gauze, it means that the patient's incisional bleeding has been occurring for some time. The larger the gaps in the gauze, the longer the blood will appear on the upper gauze, and the longer the patient's condition will require observation.

[0004] Therefore, how to provide a neck dressing suitable for bandaging the patient's incision after thyroid surgery to improve the bandaging efficiency and the patient's safety is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0035] See also Figure 1-2 The present embodiment provides a postoperative neck dressing, which includes an outer layer 1, a water-absorbing layer 2 and a contact layer 3. The water-absorbing layer 2 is arranged between the outer layer 1 and the contact layer 3, and the water-absorbing layer 2 is bonded to the outer layer 1, and the contact layer 3 is bonded to the water-absorbing layer 2; wherein, a humidity sensor 4 is arranged inside the water-absorbing layer 2, and an alarm device 5 is arranged on the outer layer 1. The humidity sensor 4 includes a humidity-sensing film 41, interdigital electrodes 42 and a substrate 43, and the humidity-sensing film 41 and the interdigital electrodes 42 are both arranged on the substrate 43; the end of the interdigital electrode 42 is also connected to two pins 44, and the two pins 44 are both located outside the substrate 43 and electrically connected to the alarm device 5; the humidity-sensing film 41 is located between the two pins 44 and the interdigital electrode 42, and the humidity-sensing film 41 is in contact with the interdigital electrode 42.

[0036] Specifically, the utility model provides a postoperative neck dressing, including an outer layer 1, a water-absorbing layer 2 and a contact layer 3. The water-absorbing layer 2 is arranged between the outer layer 1 and the contact layer 3, and the water-absorbing layer 2 is bonded to the outer layer 1, and the contact layer 3 is bonded to the water-absorbing layer 2. As a feasible way, the outer layer 1 and the contact layer 3 are both made of skin-friendly cotton sterile dressing, and the water-absorbing layer 2 is made of sponge with strong water absorption; in addition, a humidity sensor 4 is provided inside the water-absorbing layer 2, and an alarm device 5 is provided on the outer layer 1, which is used to detect whether there is exudation or bleeding at the patient's incision site, and to remind medical staff or caregivers to come and deal with it in time; the humidity sensor 4 includes a humidity sensing membrane 41, an interdigitated electrode 42 and a substrate 43. The humidity sensing membrane 41 can be used to detect the humidity in the surrounding environment. Since the inner dressing has good air permeability and water permeability, if the patient has body fluid or blood exudation from the incision during use, the body fluid or blood can quickly pass through the contact layer 43. The touch layer 3 reaches the water-absorbing layer 2 with a sensing device. Since the water-absorbing layer 2 has strong water absorption, when the humidity of the water-absorbing layer 2 reaches a certain range, the moisture-sensing film 41 on the humidity sensor 4 placed inside the water-absorbing layer 2 contacts the interdigital electrodes 42. The interdigital electrodes 42 are affected by the humidity and change the resistivity and resistance value, thereby sensing the change in humidity in the surrounding environment; as a feasible way, the outer layer 1 and the water-absorbing layer 2 are connected by bonding, and at the same time, the edges of the water-absorbing layer 2 and the contact layer 3 are further fixed to the outer layer 1 through a pressing process, which can prevent the position of the inner layer dressing from shifting and loosening or affecting the adsorption due to patient activities; thereby, a neck dressing with a warning function that is convenient for bandaging and treating patients' incisions after thyroid surgery is constructed, shortening the time for discovering bleeding from the patient's incision, avoiding consequences such as shock or suffocation caused by heavy bleeding or exudation from the incision, and ensuring the safety of the patient.

[0037] Furthermore, during the use of the dressing, if the patient's incision produces exudation or bleeding, the body fluid or blood will be absorbed by the water-absorbing layer 2 through the contact layer 3. When the humidity of the water-absorbing layer 2 reaches a certain range, the moisture-sensing membrane 41 and the interdigital electrodes 42 are sensed by the change in humidity in the environment, and the alarm device 5 is connected to sound an alarm. The alarm sound promptly reminds medical staff or caregivers that the patient's incision is bleeding at the current moment and needs to be dealt with in time, so as to shorten the time of discovery of incision bleeding, detect it early, intervene early, and avoid large amounts of incision bleeding causing shock to the patient or compression of the trachea to cause suffocation.

[0038] In some possible implementations, two through-holes 6 are provided on the outer layer 1 , and the two pins 44 pass through the two through-holes 6 and are electrically connected to the alarm device 5 ; the opening positions of the two through-holes 6 are adapted to the layout positions of the two pins 44 .

[0039] Specifically, by setting the perforation 6, when preparing the dressing, the two pins 44 can be respectively passed through the two perforations 6 to be electrically connected to the alarm device 5, such as Figure 1 As shown, the opening positions of the two through holes 6 are adapted to the layout positions of the two pins 44; in addition, Figure 1 The figure only shows the connection relationship between the two pins 44 and the alarm device 5. In actual preparation, the two pins 44 are of regular length and are directly inserted through the two perforations 6 and connected to the alarm device 5. At the same time, the position of the perforations 6 can bypass the edge pressing of the water-absorbing layer 2 and the contact layer 3.

[0040] In some possible embodiments, a bonding area 7 is provided on the outer surface of the outer layer 1 , and the two perforations 6 are both located in the bonding area 7 ; the size of the bonding area 7 is adapted to the alarm device 5 , and the bottom of the alarm device 5 is bonded to the bonding area 7 .

[0041] Specifically, the alarm device 5 is fixed by providing the adhesive area 7 .

[0042] In some possible embodiments, the outer layer 1 is larger than the water-absorbing layer 2 and the contact layer 3 , and the inner side of the outer layer 1 is covered with an adhesive layer. The water-absorbing layer 2 is bonded to the adhesive layer, and the adhesive layer is bonded to human skin.

[0043] Specifically, the outer layer 1 is the largest among the outer layer 1, the water-absorbing layer 2 and the contact layer 3, and the portion exceeding the water-absorbing layer 2 and the contact layer 3 is provided with adhesiveness, which can be bonded to the patient's skin; the water-absorbing layer 2 and the contact layer 3 are relatively small in size and can cover the patient's incision without affecting the adhesive area around the first layer.

[0044] In some possible embodiments, the water absorption layer 2 and the contact layer 3 are both arranged in the middle of the outer layer 1, and the humidity sensor 4 is arranged in the middle of the water absorption layer 2; the substrate 43 is arranged close to the outer layer 1, and the humidity sensing film 41 and the interdigitated electrode 42 are arranged close to the contact layer 3.

[0045] Specifically, the humidity sensor 4 is located in the middle, which can promptly and quickly sense the bleeding and fluid leakage at the incision; the humidity sensing membrane 41 and the interdigital electrodes 42 are arranged close to the contact layer 3 to improve the detection sensitivity of the humidity of the surrounding groove environment.

[0046] In some possible implementations, a buzzer and a power supply are provided in the alarm device 5 , and the buzzer and the interdigital electrodes 42 are electrically connected to the power supply.

[0047] Specifically, by setting up a buzzer and a power supply, a buzzer alarm can be sounded when the humidity at the incision rises to within a preset range, so as to remind medical staff and caregivers to come and check and deal with it; as a feasible way, the alarm device 5 can be a small piezoelectric buzzer or electromagnetic buzzer or patch buzzer with a buzzer, or a buzzer chip can be used to reduce the overall volume of the alarm device 5; on the basis of reducing the overall device volume, the specific structure and layout of the power supply and buzzer can be rationally arranged using existing technology.

[0048] In some possible embodiments, the moisture-sensing film 41 is made of moisture-sensitive material; the base sheet 43 is made of flexible material; the water-absorbing layer 2 is made of absorbent medical sponge material; the outer layer 1 and the contact layer 3 are both made of skin-friendly cotton sterile dressing.

[0049] Specifically, the humidity sensing film 41 is made of a humidity-sensitive material to facilitate sensing humidity changes; the substrate 43 is made of a flexible material to improve the softness of the humidity sensor 4, making it softer than conventional humidity sensors 4, thereby avoiding pressure and discomfort on the patient's skin.
