Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wound compression hemostasis after surgery, specifically a postoperative pressure hemostasis device for ear surgery. Background Technology
[0002] After ear surgery, a surgical incision is created on the patient's ear, such as in the incision of a preauricular fistula. Postoperatively, pressure bandaging is required at this incision site. Current techniques typically involve stacking one or more thick gauze pads over the incision and then wrapping and securing the gauze pads around the patient's head. The pressure applied during wrapping achieves hemostasis at the postoperative incision site. However, existing methods of postoperative pressure hemostasis for ear surgery are not only cumbersome to apply, but also require removal and re-bandaging if the pressure hemostasis is ineffective. Furthermore, the poor ventilation at the pressure point during hemostasis hinders wound healing. Utility Model Content
[0003] The present invention aims to at least partially solve one of the technical problems in the related art: to provide a postoperative pressure hemostasis device for ear surgery, which is convenient to operate for the pressure hemostasis process at the incision site after ear surgery, can adjust the pressure arbitrarily according to the pressure hemostasis effect, and can improve the air permeability of the pressure site.
[0004] Therefore, one objective of this utility model is to provide a postoperative pressure hemostasis device for ear surgery, which includes a headband with a compression device for hemostasis. The compression device includes a base, an elastic air cushion, and hemostatic gauze. The base is connected to the headband, and the rear end of the elastic air cushion is detachably connected to the base. The hemostatic gauze is attached to the front end of the elastic air cushion and fixed to it by a connector. The elastic air cushion has a pressure chamber and a ventilation chamber inside. Several vent holes are evenly distributed on the front end of the elastic air cushion. A first air bladder and a second air bladder are provided below the elastic air cushion for providing compressed air. The first air bladder is connected to the pressure chamber, and the second air bladder, the ventilation chamber, and the vent holes are connected in sequence. On one hand, once the headband is placed on the patient's head, the compression device can be aligned with the surgical incision site on the patient's ear. At this point, the hemostatic gauze at the front end of the compression device adheres to the patient's wound for initial compression hemostasis. Then, medical staff pressurize the pressure chamber through the first air balloon. As the pressure inside the pressure chamber increases, the pressure exerted by the hemostatic gauze on the patient's wound increases until the ideal compression hemostasis effect is achieved. On the other hand, during the postoperative recovery process, the patient can squeeze the second air balloon to send airflow into the ventilation chamber, which then exits through various vents. Because the hemostatic gauze has a porous structure, the airflow from the vents will escape through the small gaps in the hemostatic gauze, making the hemostatic gauze highly breathable. The patient can reduce redness, swelling, and heat at the wound site through the airflow, thus improving patient comfort and keeping the wound dry, which is conducive to wound healing.
[0005] According to one example of the present invention, the base is detachably connected to the headband strap, and the relative position between the base and the headband strap is adjustable.
[0006] According to one example of this utility model, the headband has a plurality of small holes spaced apart circumferentially and axially, and the base is provided with a positioning rod that can be inserted into any of the small holes. By selecting the insertion of the positioning rod into different small holes, the base can be fixed at different positions on the headband, thereby allowing the relative positions of the base and the headband to be adjusted in advance according to the individual differences in the actual patient's head shape and wound location.
[0007] According to one example of this utility model, a thickening pad is provided between the elastic air cushion and the base, and the two sides of the thickening pad are detachably connected to the elastic air cushion and the base, respectively. The thickening pad can increase the thickness of the compression device, which allows the hemostatic gauze to fit more closely to the surgical incision site on the patient's ear for patients with smaller head circumferences.
[0008] According to one example of this utility model, the two sides of the thickening pad are respectively attached to the elastic air cushion and the base via Velcro. The thickening pad is easily secured by attaching and detaching the male and female sides of the Velcro.
[0009] According to one example of the present invention, there are multiple thickening pads, which are stacked along the thickness direction and glued to each other. The first thickening pad is glued to the elastic air cushion, and the last thickening pad is glued to the base.
[0010] According to one example of this utility model, the connector is a strip of gauze. The two ends of the gauze strip are clamped between the elastic air cushion and the base, and the middle portion of the gauze strip wraps around the elastic air cushion and the hemostatic gauze on it, so that the hemostatic gauze adheres to the elastic air cushion. The strip of gauze can be used to pre-fix the hemostatic gauze to the front end face of the elastic air cushion by wrapping it around once or multiple times. When the elastic air cushion is installed on the base, the two ends of the gauze strip can be well clamped between the elastic air cushion and the base, thus making the installation and replacement of the hemostatic gauze more convenient.
[0011] According to one example of this utility model, the connector is a strip of medical tape.
[0012] According to one example of this utility model, the elastic air cushion has auxiliary air chambers on both sides along its width direction, and the auxiliary air chambers extend along the length direction to form an elongated structure. The function of the auxiliary air chambers is that when the gauze strip or tape pre-fixes the hemostatic gauze to the elastic air cushion, as the pressure chamber is pressurized and bulges, it will tighten the gauze strip or tape, and even break it. At this time, the taut gauze strip or tape will compress and deform the auxiliary air chamber, thus reducing the tension on the gauze strip or tape.
[0013] According to one example of this invention, the headband is equipped with two compression devices, which are spaced apart circumferentially along the headband. This facilitates simultaneous compression and hemostasis of both ears after surgery.
[0014] The above technical solution has the following advantages or beneficial effects: First, after the headband is placed on the patient's head, the compression device can be aligned with the surgical incision site on the patient's ear. At this time, the hemostatic gauze at the front end of the compression device adheres to the patient's wound for initial compression hemostasis. Then, medical staff pressurize the pressure chamber through the first air balloon. As the pressure in the pressure chamber increases, the pressure exerted by the hemostatic gauze on the patient's wound increases until the ideal compression hemostasis effect is achieved. Second, during the postoperative recovery process, the patient can squeeze the second air balloon to send airflow into the ventilation chamber and out through various vents. Because the hemostatic gauze has a porous structure, the airflow emitted from the vents will pass through the small gaps in the hemostatic gauze. The internal drainage design ensures good breathability of the hemostatic gauze, allowing patients to reduce redness, swelling, and heat at the wound site through airflow. This improves patient comfort and keeps the wound dry, promoting healing. Secondly, the thickened pad increases the thickness of the compression device, allowing the hemostatic gauze to fit the surgical incision site near the ear better for patients with smaller head circumferences. Furthermore, using strip-shaped gauze as connectors allows the hemostatic gauze to be pre-fixed to the front end of the elastic air cushion by wrapping it around one or more times. When the elastic air cushion is installed on the base, the two ends of the gauze strip are securely clamped between the elastic air cushion and the base, making installation and replacement of the hemostatic gauze more convenient.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0026] The postoperative pressure hemostasis device for ear surgery according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0027] This utility model provides a postoperative pressure hemostasis device for ear surgery, as shown in the figure. It includes a headband 1, on which a pressure device for applying pressure to the surgical incision of the patient's ear for hemostasis is provided. The pressure device includes a base 2, an elastic air cushion 3, and hemostatic gauze 4. The base 2 is connected to the headband 1, and the rear end of the elastic air cushion 3 is detachably connected to the base 2. The hemostatic gauze 4 is attached to the front end face 3.1 of the elastic air cushion 3 and fixed to the elastic air cushion 3 by a connector. The elastic air cushion 3 has a pressure chamber 3.3 and a ventilation chamber 3.4 inside. Several ventilation holes 3.6 are evenly distributed on the front end face 3.1 of the elastic air cushion 3. A first air bladder 5 and a second air bladder 6 for providing compressed air are provided below the elastic air cushion 3. The first air bladder 5 is connected to the pressure chamber 3.3, and the second air bladder 6, the ventilation chamber 3.4, and the ventilation holes 3.6 are connected in sequence.
[0028] In a preferred embodiment of the above, the base 2 and the headband strap 1 are detachably connected, and the relative position between the base 2 and the headband strap 1 is adjustable.
[0029] Preferably, the headband strap 1 has a plurality of small holes 1.1 spaced apart circumferentially and axially, such as... Figures 1-3As shown, all the small holes 1.1 are divided into three layers along the axial direction: upper, middle, and lower. Each layer of small holes 1.1 is spaced apart. Within the same layer, the small holes 1.1 are spaced apart circumferentially along the headband strap 1. The base 2 is equipped with a positioning rod (not shown in the figure) that matches the small holes 1.1, allowing the positioning rod to be inserted into any one of the small holes 1.1. The positioning rod is fixed to the base 2 at its rear end and has a spherical head at its front end with a diameter slightly larger than that of the small hole 1.1. This allows the front end of the positioning rod to overcome the elastic deformation of the small hole 1.1 and pass through it, thus achieving a fixed connection between the base 2 and the headband strap 1.
[0030] Preferably, such as Figure 1-2 As shown, the base 2 has a ring that fits onto the headband strap 1. The ring slides in conjunction with the headband strap 1, allowing the base 2 to be adjusted circumferentially along the headband strap 1. Further, the base 2 is fixedly connected to the ring, or the base 2 is snapped into the ring. Different snap fasteners on the base 2 are fixed to the ring, allowing the position of the base 2 relative to the ring to be adjustable. These snap fasteners are conventional connecting components in the prior art; therefore, their structure will not be described in detail in this embodiment. It should be understood that snap fasteners at different positions on the base 2 are snapped into and fixed to matching snap fasteners on the ring, thereby achieving adjustable relative position between the base 2 and the ring.
[0031] like Figure 1 and Figure 2 As shown, the headband strap 1 has a ring structure. Alternatively, the headband strap 1 can be a strip of elastic strap, with both ends connected by a buckle, thereby connecting the two ends of the headband strap 1 to form a ring structure.
[0032] Based on the above embodiments, the head circumference of different patients varies greatly. Therefore, the same headband 1 will have a different degree of pressure on the surgical incision of the ear of different patients. In order to meet the needs of different patients, the improvement of this embodiment is that: a thickening pad 7 is provided between the elastic air cushion 3 and the base 2, and the two sides of the thickening pad 7 are detachably connected to the elastic air cushion 3 and the base 2 respectively.
[0033] Furthermore, the two sides of the thickening pad 7 are respectively attached to the elastic air cushion 3 and the base 2 via Velcro. The Velcro includes a hooked side and a soft side, with the hooked and soft sides respectively located on both sides of the thickening pad 7. The elastic air cushion 3 and the base 2 have corresponding female and male sides that match the hooked and soft sides on the thickening pad 7. Thus, the elastic air cushion 3, the thickening pad 7, and the base 2 can be fixedly connected by two female and two male sides. Each female and male side is fixed to the corresponding elastic air cushion 3, thickening pad 7, or base 2.
[0034] Furthermore, the thickening pad 7 is multiple, such as... Figure 2 As shown, there are three thickening pads 7. Multiple thickening pads 7 are stacked sequentially along the thickness direction and any two adjacent thickening pads 7 are fixed to each other by Velcro. The first thickening pad 7 is fixed to the elastic air cushion 3, and the last thickening pad 7 is fixed to the base 2. Thus, the number of thickening pads 7 can be increased or decreased arbitrarily according to the actual needs of use. The elastic air cushion 3, all the thickening pads 7 and the base 2 can be fixed sequentially along the thickness direction.
[0035] Improvements based on the above embodiments: such as Figure 8 As shown, the connector is a strip of gauze 8. Both ends of the gauze strip 8 are clamped between the elastic air cushion 3 and the base 2. The middle portion of the gauze strip 8 wraps around the elastic air cushion 3 and the hemostatic gauze 4 on the elastic air cushion 3, so that the hemostatic gauze 4 adheres to the elastic air cushion 3. Before each use, medical personnel can stack one or more pieces of hemostatic gauze 4 on the front end face 3.1 of the elastic air cushion 3, and then use the entire roll of gauze strip 8 to wrap the hemostatic gauze 4 around the elastic air cushion 3 in a loop, so that the end of the gauze strip 8 is located on the rear end face 3.2 of the elastic air cushion 3. At this time, the rear end of the elastic air cushion 3 is connected to the base 2. During this process, the end of the gauze strip 8 is clamped between the elastic air cushion 3 and the base 2, thus completing the installation of the hemostatic gauze.
[0036] It should be understood that when the rear end of the elastic air cushion 3 is fixedly connected to the base 2 by Velcro, the width of the gauze strip 8 should be less than the length of the elastic air cushion 3, so that when the gauze strip 8 is wrapped around the elastic air cushion 3 in the width direction of the elastic air cushion 3, most of the Velcro on the rear end face 3.2 of the elastic air cushion 3 can be exposed, thereby allowing the elastic air cushion 3 to be fixed to the base 2 by Velcro.
[0037] Preferably, the connector can also be a strip of medical tape.
[0038] Based on the preferred embodiment of the connector, such as Figure 8 As shown, the elastic air cushion 3 has auxiliary air chambers 3.5 on both sides along its width direction. Each auxiliary air chamber 3.5 is a closed air chamber and extends along its length to form a long strip structure. When the gauze strip 8 is wrapped around the elastic air cushion 3 along its width direction, the gauze strip 8 is in a taut state. When the pressure chamber is inflated, it further tightens the gauze strip 8. The auxiliary air chambers 3.5 allow the gauze strip 8 to tighten around them, causing the auxiliary air chambers 3.5 to contract. This effectively prevents the gauze strip 8 from becoming too tight, and avoids the hemostatic gauze from being deformed by pressure.
[0039] Preferably, such as Figure 1As shown, the headband 1 is equipped with two compression devices, which are arranged at intervals along the circumference of the headband 1. The two compression devices are generally symmetrically arranged in the horizontal direction to simultaneously apply pressure to the surgical incisions on both ears of the patient for hemostasis. However, since the positions of the two compression devices can be arbitrarily adjusted according to the actual incision locations on the patient's two ears, and the headband 1 can be made of a flexible elastic bandage, the two compression devices are not absolutely symmetrically arranged, but should still be understood as being symmetrically arranged in the horizontal direction.
[0040] The length direction in the above embodiments refers to Figure 7 The vertical direction and the width direction refer to Figure 7 The direction perpendicular to the paper surface, and also the width direction corresponds to Figure 8 The up and down directions in the middle.
[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
[0042] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
