Description

Technical Field

[0001] This invention relates to the field of medical assistive devices, specifically to a scalp expansion and protection device. Background Technology

[0002] For patients with large areas of skin loss, the current common practice is to repair the damaged skin through skin grafting. Small areas of skin grafts can be taken from any part of the body, but large areas of skin grafts often do not have enough skin. Therefore, a skin expander needs to be implanted in the patient's body before the operation to expand the skin and meet the skin grafting needs of patients with large areas of skin loss.

[0003] Currently, the most commonly used method is the balloon-injected water-filled skin expander. An expandable balloon is implanted at the site where skin is to be harvested, and water is intermittently injected into the expander as needed. However, as the weight of the expander increases, it may shift downwards, causing pressure on the patient's skin and affecting the effectiveness of skin expansion. This is especially true when the expander is implanted near the head, where tilting or shifting can cause significant discomfort. Therefore, a support structure needs to be designed to support the expander. Summary of the Invention

[0004] The present invention aims to provide a scalp expansion and protection device to support and protect the scalp when an expander is implanted in the head to expand the scalp.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a head skin expansion protection device, which includes a base and a support unit. A fixing member is fixed on the base, and the support unit is fixed on the base. The support unit includes an expansion member and a first support assembly. The first support assembly includes a plurality of first airbags. The plurality of first airbags are fixed on the top of the base and distributed sequentially along the length direction of the base. The expansion member communicates with the first airbags and is used to inflate the first airbags.

[0006] The beneficial effects of this plan are:

[0007] The fasteners in this design connect the two ends of the base, allowing it to be worn on the patient's head. Once worn, several first airbags form a ring around the scalp where the expander is implanted. When inflated, these first airbags limit the position of the scalp containing the expander, preventing it from tilting or shifting to the side. This effectively reduces scalp pain and prevents congestion if the expander tilts, while also protecting the scalp from tearing and facilitating transplantation.

[0008] Furthermore, the support unit also includes a second support assembly, which includes several second airbags. The several second airbags are also fixed to the top of the base and distributed sequentially along the length of the base. The expansion member communicates with the second airbags and is used to inflate the first airbag.

[0009] The beneficial effects of this solution are as follows: the first and second airbags are located in different positions, and the pressure on the scalp is also different when using them. When using them, the first and second airbags can be used alternately, so that the pressure on the scalp can be changed, avoiding discomfort caused by applying pressure to the same position for a long time.

[0010] Furthermore, the first airbag and the second airbag are spaced apart, and the inflator alternately communicates with the first airbag and the second airbag.

[0011] The beneficial effects of this solution are as follows: the first and second airbags in this solution are both distributed along the circumference of the expander. When only the first or second airbag is used, the expander can still be limited from different directions, further preventing the expander from tilting or even shifting.

[0012] Furthermore, suction cups are detachably attached to the side walls of the base.

[0013] The beneficial effects of this solution are: when used for a long time, the suction cup can be attached to the scalp to position the base. At this time, the fixing parts can be loosened, reducing the pressure of the base on the head and avoiding discomfort caused by prolonged pressure on the head.

[0014] Furthermore, the fastener is a latch.

[0015] The beneficial effect of this solution is that the locking mechanism can more conveniently and quickly connect the two ends of the fastener.

[0016] Furthermore, the fastener is a strap.

[0017] The advantages of this solution are that, compared to buckles, straps are generally softer and more comfortable to use.

[0018] Furthermore, the base includes an elastic frame and a flexible layer covering the elastic frame.

[0019] The beneficial effects of this solution are as follows: the elastic skeleton in this solution can bend under pressure, making the base fit the head more closely, and compared with the flexible layer, the elastic skeleton is stronger and can provide better support for the expander; while the flexible layer is softer and more comfortable when in contact with the skin.

[0020] Furthermore, the elastic frame includes a vertical part and a horizontal part that are fixedly connected. The end of the horizontal part away from the vertical part is provided with a support rod and a locking member for positioning the support rod. The support rod corresponds one-to-one with the first airbag, and the outer wall of the first airbag is provided with a positioning groove opposite to the support rod.

[0021] The beneficial effects of this solution are as follows: When the expander is large, the pressure on the first airbag is relatively high. If the pressure inside the first airbag is increased by filling it with a large amount of gas to increase the support force on the expander, it was found in experiments that the first airbag is not flexible enough, causing discomfort to the skin where the expander is implanted. Conversely, if the pressure in the first airbag is reduced, the first airbag will tilt away from the head under the pressure of the expander, resulting in less support for the expander.

[0022] In this design, the support rod can limit the position of the first airbag, preventing it from tilting away from the head. Even when limited, the first airbag remains relatively flexible, maintaining good support for the expander. Furthermore, rotating the support rod adjusts the limiting effect on the first airbag, thereby changing the support effect on the expander and expanding its application range.

[0025] Figure 3 This is a partial cross-sectional view of Embodiment 3 of the present invention. Detailed Implementation

[0026] The following detailed description illustrates the specific implementation method:

[0027] The reference numerals in the accompanying drawings include: base 1, strap 11, suction cup 2, connecting rod 21, first airbag 3, second airbag 4, and locking rod 5.

[0028] Example 1

[0029] A scalp expansion protection device, such as Figure 1 and Figure 2As shown, the device includes a base 1 and a support unit. The base 1 includes an elastic frame and a flexible layer. The flexible layer covers the outside of the elastic frame. In this embodiment, the flexible layer is made of latex material, and the elastic frame is made of elastic plastic material. In actual implementation, a thin metal sheet can also be used, allowing the base 1 to bend into an arc shape that fits against the head. The base 1 is equipped with a fixing component. In this embodiment, the fixing component uses two straps 11. Both ends of the elastic frame have fixing holes. One end of each strap 11 passes through the fixing hole and connects to the elastic frame. The other end of each strap 11 passes through the flexible layer and extends to the outside of the flexible layer. In actual implementation, the fixing component can be a single strap, with one end fixed to one end of the base 1. When the base 1 needs to be fixed, the end of the strap is passed through the fixing hole on the elastic frame at the other end of the base 1 and fixed. Alternatively, the fixing component can be a buckle, with the movable part and the fixed part of the buckle fixed to both ends of the base 1 respectively. When the base 1 needs to be fixed, the movable part of the buckle is connected to the fixed part to quickly connect the two ends of the fixing base.

[0030] The base 1 has several suction cups 2 on its side wall facing the head. The suction cups 2 are distributed in sequence with gaps along the length of the base 1 and face the head. Specifically, in this embodiment, a connecting rod is glued to the suction cup 2. The end of the connecting rod away from the suction cup 2 passes through the flexible layer and the elastic skeleton and is gap-fitted with the elastic skeleton, so that the connecting rod can slide out of the base 1 to disassemble and install the suction cup 2.

[0031] The support unit includes an expansion component, a first support assembly, and a second support assembly. In this embodiment, the expansion component is an air pump. In actual implementation, the expansion component can also be a water pump, or both an air pump and a water pump can be used simultaneously. The air outlet of the air pump is connected to the first expansion pipe and the second expansion pipe through a three-way valve. When the expansion component uses both an air pump and a water pump, the outlets of both the air pump and the water pump are connected to the first expansion pipe and the second expansion pipe through a three-way valve.

[0032] The first support assembly includes several first airbags 3, and the second support assembly includes several second airbags 4. The first airbags 3 and second airbags 4 are distributed sequentially along the length of the base 1, and are spaced apart. The bottoms of the first airbags 3 and second airbags 4 are glued to the top of the base 1. The tops of the first airbags 3 and second airbags 4 are provided with exhaust ports and exhaust plugs, and the exhaust plugs are engaged with the exhaust ports to seal them. The first airbags 3 are connected to the first expansion tube through pipes, and the second airbags 4 are connected to the second expansion tubes through pipes.

[0033] The specific implementation process is as follows:

[0034] In use, place base 1 below the expander and bend base 1 so that it fits against the patient's head. Then, connect the two ends of base 1 using the fastener and place base 1 on the patient's head. At this time, the first airbag 3 and the second airbag 4 are distributed circumferentially along the expander. Then, activate the expansion mechanism to inflate the first airbag 3, causing it to expand and support the expander. After a period of use, open the vent on the first airbag 3 to release the gas, and then inflate the second airbag 4 through the expansion mechanism, causing it to expand and support the expander. At this time, the first airbag 3 relaxes the expander, no longer applying pressure to the scalp, avoiding discomfort caused by prolonged pressure on the same area of ​​the scalp and preventing obstruction of blood circulation.

[0035] Example 2

[0036] Based on Example 1, such as Figure 3 As shown, the elastic frame in this embodiment includes an integrally formed vertical part and several horizontal parts. The several horizontal parts are distributed sequentially along the length of the vertical part. A locking rod 5 is detachably connected to the right end of each horizontal part. Specifically, several slots are provided at the top of the horizontal part, and the lower end of the locking rod 5 is inserted into the slots. In this embodiment, the upper end of the locking rod 5 is inclined towards the side closer to the first airbag 3 or the second airbag 4, and abuts against the first airbag 3 or the second airbag 4. In actual implementation, a positioning plate can also be hinged to the upper end of the locking rod 5, abutting against the first airbag 3 and the second airbag 4, increasing the contact area with the first airbag 3 and the second airbag 4, and improving the support effect. In this embodiment, elastic sheets are hinged to the right walls of both the first airbag 3 and the second airbag 4, forming positioning grooves between the elastic sheets and the outer walls of the first airbag 3 and the second airbag 4. The upper end of the locking rod 5 is located in the positioning groove, supporting the first airbag 3 and the second airbag 4.

[0037] When the expander is large, the locking rod 5 supports the first airbag 3 and the second airbag 4, limits the first airbag 3 and the second airbag 4, and prevents the first airbag 3 and the second airbag 4 from tilting outward, thereby maintaining a better support effect for the expander.
