Description

Technical Field

[0001] The utility model relates to the technical field of postoperative nursing for surgeries, in particular to a pressure dressing device and a pressure dressing machine for craniotomy wounds after surgery. Background Art

[0002] Subcutaneous hydrops is one of the common complications in neurosurgery, which can be seen in skull repair, intracranial tumors, cerebral hemorrhage, etc. Among them, relevant literature points out that the incidence of subcutaneous hydrops in patients after intracranial tumor surgery is about 30%. After the craniotomy wound is pressure-dressed, subcutaneous hydrops can be reduced. Due to the traditional elastic bandage pressure dressing, it cannot targetedly apply pressure to the wound area, and the pressure magnitude is uncontrollable. When the pressure is too small, it is easy to fall off and cannot achieve the pressure effect; when the pressure is too large, the blood circulation in the compressed area is poor, and subcutaneous necrosis or pressure injuries at the bandage edge, near the wound, at the back of the head, and the auricle are likely to occur.

[0003] Therefore, the traditional wound pressure dressing has the problem that the pressure magnitude and area are uncontrollable, which in turn affects postoperative recovery. Content of the Utility Model

[0004] In view of the above problems, the utility model aims to provide a pressure dressing device and a pressure dressing machine for craniotomy wounds after surgery. By setting an airbag in the covering part and fixing the tightening unit, the problem that the traditional wound pressure dressing has uncontrollable pressure magnitude and area and thus affects postoperative recovery is solved to a certain extent, and the purpose of regional pressure application to the wound with controllable pressure is achieved.

[0005] In a first aspect, the utility model provides a pressure dressing device for craniotomy wounds after surgery, including: a covering part, an airbag, and a tightening unit; the covering part includes a covering outer surface and a covering inner surface connected to each other, and the covering inner surface abuts against the human head; the airbag is fixed to the covering inner surface; the tightening unit is connected to the covering outer surface; the covering part is fixed to the human head through the tightening unit.

[0006] In the utility model, after craniotomy surgery, instead of using the traditional bandage fixation, the airbag is used to abut against the wound area, which can make the wound receive uniform force; the covering part is fixed to the human head by using the tightening unit, which can prevent the covering part from falling off. At the same time, the force on the wound and the force on the fixing device are not in the same position, and the regional pressure application is more targeted, which is beneficial to postoperative recovery.

[0007] Furthermore, in the above pressure dressing device for craniotomy wounds after surgery, it further includes a pressure regulating part connected to the airbag; the pressure regulating part includes a pneumatic pressure bladder, a pressure extension tube, and a control valve; the pneumatic pressure bladder, the pressure extension tube, and the airbag are sequentially connected; the control valve is arranged on the pressure extension tube.

[0008] In the present utility model, through the provided pressure adjustment part, the airbag pressure can be adjusted timely, including pressurized inflation and decompressed deflation; and, the gas flow is adjusted through the control valve to meet the changing needs of users.

[0009] Furthermore, in the above-mentioned device for pressure dressing of the wound after craniotomy, the pressure adjustment part further includes a pressure detection unit; the pressure detection unit is connected to the airbag.

[0010] In the present utility model, by setting the pressure detection unit, the airbag pressure data becomes clearer and more specific, facilitating the operator to grasp the specific data in real time.

[0012] In the present utility model, after the hemispherical covering part is worn, it can better fit the head and is not easy to fall off, and is beneficial to the acting force between the airbag and the wound.

[0013] Furthermore, in the above-mentioned device for pressure dressing of the wound after craniotomy, the outer surface of the covering is made of non-woven fabric.

[0014] In the present utility model, using non-woven fabric as the outer surface of the covering has good air permeability and water absorption, and poor stretchability, which is beneficial to the airbag applying pressure to the wound after inflation.

[0015] Furthermore, in the above-mentioned device for pressure dressing of the wound after craniotomy, the tightening unit includes a strap, a button and through holes; the button is arranged at one end of the strap; there are several through holes; several said through holes are evenly distributed along the length direction of the strap.

[0016] In the present utility model, the cooperation mode of the button and the through holes enables the perimeter size of the covering part to be adjustable, and human heads of different sizes can be worn, and the tightening pressure is moderate; at the same time, after wearing, the ear-exposing design can prevent pressure injuries to a certain extent.

[0022] In the present utility model, microwave irradiation has a good effect on the healing of the incision. It mainly utilizes the thermal effect of microwaves on organisms, which can significantly improve the blood circulation of deep tissues in the trauma area and promote the metabolism and regeneration ability of tissue cells. Local microwave irradiation can also increase the activity of enzymes, enhance the phagocytic ability of white blood cells, and promote the absorption and dissipation of effusion. Therefore, it can relieve local pain and swelling, prevent incision infection, and accelerate the healing of the surgical wound surface.

[0023] Further, in the above-mentioned wound compression dressing machine after craniotomy, there are multiple airbags; the multiple airbags are distributed in a honeycomb shape on the inner surface of the covering.

According to the area of the wound, different positions of the honeycomb above the wound are selected for inflation through the electronic screen and the airbag pressure is remotely adjusted, avoiding subcutaneous necrosis or pressure injury and being not easy to fall off.

[0025] Since the wound compression dressing machine after craniotomy provided in this aspect includes the above-mentioned wound compression dressing device after craniotomy, it has the technical effects of the above-mentioned wound compression dressing device after craniotomy, which will not be elaborated here.

[0026] Technical advantages of the wound compression dressing device and the wound compression dressing machine after craniotomy of the present utility model:

[0027] 1. Compared with traditional elastic bandage compression, airbag compression applies pressure to the wound area according to different surgical sites, preventing the generation of subcutaneous effusion and reducing the occurrence of pressure injury near the wound, occiput, and auricle.

[0028] 2. Microwave physiotherapy can help absorb subcutaneous effusion, subside inflammation, accelerate blood circulation, promote wound healing, and reduce wound infection.

[0029] 3. The hemispherical design prevents falling off, and the ear-exposing design can prevent pressure injury.
