[0022] like Figure 1 , Figure 2a , Figure 5 As shown, they are schematic diagrams of the utility model after the adjustable pressurization device and the inflation component of the neck after surgery are assembled with airbags of different structures. It can be seen from the figure that the utility model comprises: a neck support 5 for being placed at the back of the neck of the postoperative patient; a neck strap 6 detachably connected to the neck support and used to fix the neck support at the back of the neck of the postoperative patient; an inflatable airbag 1 slidably arranged on the neck strap for providing pressure to the postoperative patient's neck wound; and an inflation component connected to the inner cavity of the airbag for adjusting the pressure of the airbag on the postoperative patient's neck wound.

[0023] Specifically, Figure 1 As shown, the device of the utility model is composed of a neck support for supporting the back of the patient's neck and a neck strap for fixing the neck support to the back of the patient's neck after surgery, forming a support frame surrounding the patient's neck, and the pressure position of the patient's neck wound is adjusted in a targeted manner through an air bag slidably connected to the neck strap, so that the air bag pressure acts vertically on the patient's neck wound, preventing exudation and hematoma formation in the surgical area, and also helping to promote wound healing.

[0024] Among them, Figure 1 , Figure 4 As shown, the neck support of the utility model is a semi-circular shape adapted to the shape of the back of the neck, and is used to cover the back of the neck of the patient after surgery. The neck support includes a ring neck 51 for surrounding the patient's neck and an arc portion 52 seamlessly connected to the lower edge of the ring neck and extending toward the big vertebra behind the patient's neck. The width of the arc portion is gradually narrowed downward from the position where it is seamlessly connected to the lower edge of the ring neck. Preferably, an inner lining layer 53 can be provided near the lower position such as the big vertebra to increase the thickness of the lower part of the arc portion, so that the neck support can better fit the physiological structure behind the human neck, and the edge of the inner lining layer extends out of the lower edge of the arc portion. During production, the neck support can be made of medical polymer low-temperature thermoplastic material, which is easy to shape, so that the neck support as a whole can adapt to the shape of the patient's neck, making the patient more comfortable after wearing it. The inner lining layer can be made of the same material as the neck support, or it can be made of different materials. In addition, a plurality of ventilation holes for ventilation that penetrate the thickness can be opened on the neck support.

[0025] In order to fix the neck support behind the patient's neck, the utility model connects the neck strap and the neck support detachably to form a ring. Figure 3As shown, the neck strap is semi-circular and made of elastic material, such as an elastic band. For easy wearing, one end of the neck support can be connected to one end of the neck strap in an undetachable manner, and the other end of the neck support can be connected to the other end of the neck strap in a detachable manner, or both ends of the neck support can be connected to both ends of the neck strap in a detachable manner. When the connection is detachable, a Velcro structure 4 can be used. For example, a Velcro sub-strip 42 is fixed to one or both ends of the neck support by gluing or other methods, and a Velcro mother-strip 41 is fixed to one or both ends of the neck strap by gluing or sewing or other methods, so that the neck support and the neck strap can be connected together by the mother-strip and the sub-strip.

[0026] In order to apply pressure to the wound of the patient after surgery, the utility model movably arranges an inflatable elastic airbag on the neck strap, and inflates the airbag through the inflatable component to adjust the pressure. Figure 2a , Figure 2b , Figure 5 As shown, the airbag is an annular airbag with a through hole 11 in the center for the neck strap to pass through. When designing, the through hole size is slightly larger than the neck strap size so that the airbag can move freely on the neck strap. The through hole can be an elliptical hole (such as Figure 5 As shown), it can also be a square hole (as shown Figure 2a The utility model can open an air inlet 13 and an air outlet 14 on the outer side wall of the airbag away from the patient's neck (as shown in FIG. Figure 2b As shown), an air inlet 13 may be provided on the outer side wall of the airbag away from the side wall contacting the patient's neck, and an exhaust port may be provided on the upper part of the airbag (see Figure 5 ), when designing, the shapes of the air inlet and the exhaust port can be the same or different, and can be round or square (such as Figure 2b ) or other shapes. Accordingly, a manual exhaust valve 12 for opening or closing the exhaust port is provided at the exhaust port. When the pressure in the airbag exceeds the requirement, the airbag can be deflated through the manual exhaust valve so that the pressure in the airbag reaches the desired pressure. The structure of the manual exhaust valve provided at the exhaust port can adopt the existing technical structure, which will not be described in detail here. Of course, an electric exhaust valve can also be provided at the exhaust port.

[0027] In order to adjust the pressure of the airbag on the patient's neck wound, the utility model also includes an inflation component connected to the airbag cavity. The inflation component can be used as follows Figure 2aThe structure shown includes: a fixed cover 2 fixedly connected to the outside of the airbag on one side, the fixed cover and the airbag can be fixed together by pasting, etc., the fixed cover can be made of plastic material, and a thin plate can be pasted on the outside of the airbag to strengthen the connection strength between the two, and the fixed cover is fixed on the thin plate; an air pump (not shown in the figure) installed in the fixed cover, whose air outlet is connected to the air inlet of the airbag, and when connected, a threaded connection or plug-in connection can be adopted; an air pressure sensor (not shown in the figure) for detecting the pressure in the airbag is arranged on the airbag or on the air pump. In addition, a controller is arranged in the fixed cover, and a display controller 3 is arranged outside the fixed cover. The air pump, the air pressure sensor, and the display controller are electrically connected to the controller respectively. Among them, the air pressure sensor is used to monitor the pressure change in the airbag and transmit the signal to the controller for analysis and recording. After analyzing the pressure signal, the controller controls the start and stop of the air pump to perform the relevant operations of inflating or stopping the inflation of the airbag, and displays the pressure data in the airbag on the display controller. Among them, the display controller can adopt the following structure, including a display screen and an adjustment button. The output end of the controller is connected to a display screen that can display the current airbag pressure, and the input end of the controller is connected to an adjustment button for controlling the display screen switch and adjusting the pressure. The adjustment button sends a signal to the controller, and the controller controls the switch of the display screen. The display controller can also adopt other structures of the prior art. Among them, the air pump and the inflation component of the utility model adopt the structure of the prior art, such as the structure of the Mijia Inflatable Treasure or the structure of the automatic air pump for inflating outdoor air cushions, and its structure is not described in detail here.

[0028] After the patient's neck surgery is completed, the surgeon will place the neck brace behind the patient's neck in the operating room, shape it to adapt to the patient's neck shape, adjust the neck strap to make the patient comfortable, and fix it with Velcro. Move the inflatable component and the airbag to adjust the airbag to the part of the patient's neck wound that requires pressurization. The inflatable component is controlled by the pre-set pressure on the display controller to inflate the airbag, and the pressure in the airbag is observed through the display controller. The local airbag pressure is manually adjusted through the display controller and the exhaust valve according to the situation. If the pressure is insufficient, continue to inflate and pressurize. If the pressure is too high, manually deflate and reduce the pressure through the exhaust valve until the ideal pressure is reached.

[0029] In summary, the utility model of the utility model of the adjustable postoperative neck pressurization device can be used for local pressurization of the surgical area after neck surgery (such as thyroid surgery / lymph node dissection) and to adjust the pressure, wherein the adjustable pressure is reflected in the following aspects: (1) The utility model of the neck support can be made of high-molecular low-temperature thermoplastic material, and the neck strap is made of elastic belt material, and the two are detachably connected together by a Velcro structure, so that the size of the ring formed by the two can adapt to the external size of the patient's neck, making it more comfortable for the patient to use; (2) The airbag is inserted into the neck strap and can slide laterally along the neck strap, so that the compression position of the patient's neck wound can be adjusted in a targeted manner, so that the airbag pressure acts vertically on the wound, which can not only prevent exudation and hematoma formation in the surgical area, but also promote wound healing; (3) The inflation component for inflating the airbag can adjust the pressure through the display controller, so as to avoid excessive pressure compressing the patient's airway, and too low pressure cannot achieve the effect of preventing wound compression.
