Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to a postoperative pressure bag for the oral and maxillofacial region. Background Technology

[0002] Medical supplies are a general term for items used to treat wounds or diseases. The scope of medical supplies can include household medical supplies, pet medical supplies, etc. Medical supplies are very close to us. On a small scale, items needed for bandaging wounds, such as medicine bottles, plastic and transparent bottles, eye drop bottles, and liquid medicine bottles, all fall under the category of medical supplies. Generally speaking, medical supplies refer to auxiliary instruments or items used in medicine. Patients undergoing oral and maxillofacial surgery often experience varying degrees of swelling and pain in the surgical area after surgery due to the rich blood circulation and loose tissues in the oral and maxillofacial region. This increases the patient's psychological burden and affects wound healing. Postoperatively, pressure bandaging of the wound is used to eliminate the wound cavity, promote wound healing, and reduce complications. At the same time, patients are instructed to apply ice towels or wrap ice packs in two layers of sterile dressings to the local wound area for cold compresses, which helps to reduce pain, lower tissue temperature, slow tissue metabolism, and reduce tissue swelling.

[0003] The existing technology has the following technical problems: When using ice packs on patients, most methods involve placing the ice pack inside the lower end of a strap and then wrapping the strap around the top of the head for fixation. Although this method provides a relatively stable fixation, it is inconvenient for the patient to move their neck and can cause discomfort. Furthermore, the fixation process is cumbersome and inefficient. Utility Model Content

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] like Figures 1-4 As shown, to facilitate the placement and support of the ice pack, a jaw support plate 1 is included. The jaw support plate 1 has an ice pack slot 2. To facilitate the fixation of the jaw support plate 1 to the patient's jaw and face, a fastening strap 3 is fixed to the top of the jaw support plate 1. Connecting bolts 6 are fixed to both sides of the jaw support plate 1, and one end of the connecting bolt 6 is fixedly connected to an L-shaped connecting rod 7. To facilitate the up-and-down rotation of the jaw support plate 1, the L-shaped connecting rod 7 is connected to a connecting block 8 via a rotating assembly. To facilitate vertical support of the jaw support plate 1, a support frame 10 is provided at the bottom of the connecting block 8. The jaw support 1 can rotate freely left and right. A fixing block 13 is provided at the top of the support frame 10 and at the connection point with the connecting block 8. The fixing block 13 is fixedly connected to the rotating rod 14. In order to facilitate the compression of the ice pack so that the ice pack can better contact the patient's injured area, a pressure airbag 4 is provided on the inner side of the ice pack groove 2. A compression bladder 5 is fixed on the outer side of the jaw support 1. The compression bladder 5 is connected to the pressure airbag 4. In order to reduce the wear and tear of the rubber protective pad 11 on the patient's shoulders and neck and improve the wearing comfort, a rubber protective pad 11 is fixed at the lower end of the support frame 10.

[0023] In use, first place the ice pack inside the ice pack slot 2, then pull the fastening strap 3 and move the device from the patient's head to the neck. When the support frame 10 moves to the patient's shoulder, loosen the fastening strap 3 to fix the jaw support 1 to the patient. Then, by squeezing the pressure bladder 5, inflate the pressure bladder 4 so that the ice pack can fit tightly against the patient's injured area. The operation is then complete. When the patient needs to lower or raise their head, the rotating component can drive the L-shaped connecting rod 7 to rotate relative to the connecting block 8, which can also limit and support the L-shaped connecting rod 7 to a certain extent. Through the coordinated structural design of the jaw support 1, ice pack slot 2, fastening strap 3, L-shaped connecting rod 7, fixing block 13, rotating rod 14, rotating component and rubber protective pad 11, the ice pack is supported from the back of the patient's head and neck, which effectively reduces the number of steps to fix the ice pack, improves the convenience of fixation, reduces the discomfort of the patient being pulled up and down by the strap, and facilitates the movement of the patient's neck.

[0024] like Figure 3 As shown, the rotating assembly includes a rotating shaft 15, which is laterally arranged inside the connecting block 8. The rotating shaft 15 is fixedly connected to the L-shaped connecting rod 7. Multiple insertion slots are evenly opened on the outer sides of both ends of the rotating shaft 15. In order to facilitate the limiting of the L-shaped connecting rod 7, the corresponding insertion slots inside the connecting block (8) are provided with insertion components.

[0025] To facilitate limiting the rotation shaft 15, the plug-in assembly includes a plug ball 16. The plug ball 16 is located inside the connecting block 8 and at a position corresponding to the plug-in groove. The plug ball 16 is slidably connected to the connecting block 8. The plug ball 16 is plugged into the rotation shaft 15 through the plug-in groove. In order to limit the plug ball 16, a plug spring 17 is fixed on the side of the plug ball 16 away from the rotation shaft 15. The end of the plug spring 17 away from the plug ball 16 is fixedly connected to the connecting block 8.

[0026] When the L-shaped connecting rod 7 rotates, it drives the rotating shaft 15 to rotate simultaneously. When the rotating shaft 15 rotates, it presses the plug ball 16, causing the plug ball 16 to move towards the plug spring 17. When the plug spring 17 moves to the point of disengaging from the plug groove, the plug ball 16 releases its restriction on the rotating shaft 15, allowing the rotating shaft 15 to rotate. When the rotating shaft 15 rotates to another plug groove corresponding to the plug ball 16, the elastic action of the plug spring 17 pushes the plug ball 16 to the inside of the plug groove, thereby limiting the rotation shaft 15.

[0027] like Figure 4As shown, to facilitate the collection of condensate from the ice pack, a water collection box 9 is provided at the lower end of the jaw support plate 1. To facilitate the drainage of condensate from the surface of the ice pack, a water guide groove 12 is provided on the inner side of the jaw support plate 1 at a position corresponding to the ice pack groove 2. A water guide port 18 is provided at the lower end of the jaw support plate 1 at a position corresponding to the water collection box 9. The water guide port 18 is connected to the water guide groove 12. To facilitate the discharge of condensate inside the water collection box 9, a sealing water valve 19 is inserted and connected to one side of the water collection box 9. When the ice pack produces a certain amount of condensate, the condensate will flow into the inside of the water collection box 9 through the water guide groove 12 and the water guide port 18 for collection. When it is necessary to discharge the condensate inside the water collection box 9, the sealing water valve 19 can be pulled out directly to discharge the condensate inside the water collection box 9.

[0028] Working principle: In use, first place the ice pack inside the ice pack slot 2, then pull the fastening strap 3 and move the device from the patient's head towards the neck. When the support frame 10 moves to the patient's shoulder, loosen the fastening strap 3, allowing the jaw support 1 to be fixed to the patient via the fastening strap 3. Then, by squeezing the pressure bladder 5, inflate the pressure bladder 4, allowing the ice pack to fit tightly against the patient's injured area. When the patient needs to lower or raise their head, the rotating component can drive the L-shaped connecting rod 7 to rotate relative to the connecting block 8, simultaneously providing a certain degree of limitation and support for the L-shaped connecting rod 7. When the L-shaped connecting rod 7 rotates, it drives the rotating shaft 15 to rotate simultaneously. The rotation of the rotating shaft 15 compresses the insertion ball 16, causing the insertion ball 16 to move closer to the insertion spring 17. When the insertion spring 17 moves to the point of disengagement from the insertion slot, the insertion ball 16 releases its limitation on the rotating shaft 15, allowing the rotating shaft 15 to... The rotating shaft 15 can rotate. When the rotating shaft 15 rotates to the position corresponding to the other insertion slot and the insertion ball 16, the insertion ball 16 is pushed to the inside of the insertion slot under the elastic action of the insertion spring 17, thereby limiting the rotation shaft 15. Through the cooperative structural design of the jaw support plate 1, ice pack groove 2, fastening strap 3, L-shaped connecting rod 7, fixing block 13, rotating rod 14, rotating assembly and rubber protective pad 11, the ice pack can be fixed to the patient's jaw and face from the back of the patient's head and neck, thereby effectively reducing the operation steps of fixing the ice pack, improving the convenience of fixation, and reducing the discomfort of the patient being pulled up and down by the strap, and facilitating the movement of the patient's neck. When the ice pack produces a certain amount of condensation, the condensation will flow into the inside of the water collection box 9 through the water guide groove 12 and the water guide port 18 for collection. When it is necessary to drain the condensation inside the water collection box 9, the sealing water valve 19 can be pulled out directly to drain the condensation inside the water collection box 9.

[0029] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
