Description

Technical Field

[0001] This utility model relates to the field of surgical instruments, and in particular to a hemostatic cap for use in otolaryngology surgery. Background Technology

[0002] In emergency treatment, patients with head injuries such as ear, nose, throat, and neck injuries require head hemostasis and bandaging. Existing bandaging methods are complex to operate, prone to falling off, and due to differences in patient body size, universally sized head coverings cannot meet the actual hemostasis needs of different patients. If the head covering is too large or the bandage is wrapped too loosely, the hemostatic consumables will not fit tightly to the wound, resulting in insufficient pressure and affecting the hemostasis effect. If the head covering is too small or the bandage is wrapped too tightly, it will result in excessive pressure, affecting blood circulation to the wound site and external stress damage, thus affecting the treatment outcome. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this invention is to provide a hemostatic cap for use in otolaryngology surgery to solve the problems existing in the prior art, so as to keep the pressure applied to the patient's wound site constant and achieve effective hemostasis.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-2 As shown, this embodiment provides a hemostatic cap for otolaryngology surgery, including a cap body 1, an expansion element, and a pressure measuring element 6. The cap body 1 includes a head cover 2 for covering the patient's head and a restraint part 3 for covering the patient's chin and neck. The cover-up design allows the expansion element to inflate and fit tightly against the patient's ears and neck, thereby applying pressure to the wound to achieve hemostasis. When the restraint part 3 is tightened, it can fix the cap body 1 to the patient's head, thereby achieving overall fixation, so that the expansion element can stop bleeding at the wound sites such as the patient's ears and neck. The expansion element is installed on the cap. The inner side of the main body 1 has an expansion element that can inflate and deflate. When inflated, the expansion element can fit and compress the wound area on the patient's head. Through the inflation and expansion of the expansion element, the expansion element can compress the wound area to achieve a hemostatic effect. The pressure measuring element 6 is installed on the cap body 1, and the detection end of the pressure measuring element 6 extends to the expansion element. The pressure measuring element 6 is used to detect and display the pressure inside the expansion element. Based on the pressure value displayed by the pressure measuring element 6, the inflation volume inside the expansion element can be adjusted in real time to achieve a suitable pressure. The pressure can be kept constant and controllable to achieve a good hemostatic effect.

[0023] Specifically, the expansion element is an air bladder 4. By inflating the air bladder 4, pressure is applied to the wound site to stop bleeding.

[0024] This embodiment also includes a pressure-applying element 8 and a power supply 9. Both the pressure-applying element 8 and the power supply 9 are installed on the cap body 1 and close to the restraint part 3. By controlling the operation of the pressure-applying element 8, the airbag 4 is inflated and the pressure is kept within a reasonable range to maintain reasonable hemostatic pressure on the wound site, thereby achieving pressure hemostasis on the wound site. Both the pressure-applying element 8 and the pressure-measuring element 6 are electrically connected to the power supply 9 to provide electrical energy.

[0025] This embodiment also includes an external conduit 7, with the two ends of the external conduit 7 connected to a pressurizing element 8 and an airbag 4, respectively.

[0026] The pressurizing element 8 is an electric air pump, which enables automatic inflation and pressurization.

[0027] The pressurizing element 8 is equipped with an adjustment knob. By adjusting the adjustment knob, the inflation and deflation of the airbag 4 can be controlled, and the pressure inside the airbag 4 can be changed.

[0028] Airbag 4 is a hemispherical rubber airbag 4, which can play a good role in covering.

[0029] The headgear 2 is perforated (5), and the expansion element is made of transparent material. This allows for observation of bleeding at the wound site through the perforated section and the transparent expansion element, enabling adaptive adjustments based on the designed hemostasis requirements. During use, medical personnel only need to control the pressure element 8 and inflate the airbag 4. Once inflated, the airbag 4 compresses the wound site, such as the ear, nose, or throat. Bleeding can be observed through the perforated section. Once bleeding decreases, the pressure element 8 is deactivated, and the airbag 4 maintains a constant pressure, continuously compressing the wound. During this process, medical personnel can adjust the pressure element 8 based on the pressure readings of the airbag 4 displayed by the pressure measuring element 6, maintaining the airbag 4 pressure within a reasonable range to compress the bleeding wound without compressing the arteries and veins in the jaw and neck due to excessive pressure.

[0030] When using the hemostatic cap for otolaryngology surgery in this embodiment, the head cover 2 of the cap body 1 is placed over the patient's head, and the restraint part 3 is tightened to fit tightly against the patient's jaw and neck. The pressure element 8 is operated to inflate the air bladder 4. The air bladder 4 expands and applies pressure to the head wounds such as the ear and neck to stop the bleeding. The bleeding is observed through the perforated part 5. If bleeding continues, it indicates that the pressure is insufficient, and the working time of the pressure element 8 needs to be extended to allow more air to be filled into the air bladder 4 to provide greater pressure. After the bleeding is observed to have improved, the pressure element 8 is stopped. The air bladder 4 will maintain a constant pressure to achieve the hemostatic effect. The pressure measuring element 6 measures and displays the internal pressure of the air bladder 4.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
