Problems solved by technology

However, the existing skin dilators cannot accurately control the expansion pressure, and it is necessary to observe the skin color and tension in an experienced medical center to carry out water injection expansion within a reasonable pressure; Excessive pressure on the superficial skin due to excessive water injection from the dilator and high intracapsular pressure, resulting in skin ischemia or even necrosis

Abstract

The invention discloses a skin expander. The skin expander comprises an expanding sac, a pressure showing sac, a pressure indicator tube, a water injection connecting pipe and a water injection pot. One end of the expanding sac is communicated with one end of the water injection pot through the water injection connecting pipe; one end of the pressure showing sac is communicated with the pressure indicator tube, and the pressure indicator tube is fixedly connected to one end of the water injection pot; the pressure indicator tube is prefilled with gas, and the pressure showing sac is prefilled with color liquid. By means of the skin expander in the technical scheme, a user can be safely and effectively protected, and sees a doctor in time.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a skin expander. Background technique [0002] As an advanced treatment method unique to plastic surgery, the expander is to implant the skin and soft tissue expander under the normal skin and soft tissue near the lesion, and inject liquid into the expansion bag intermittently to increase the expansion capacity, so that it can exert pressure on the surface skin and soft tissue. The effect of the expansion mechanism on the local area causes the division and proliferation of tissue and epidermal cells and the expansion of the cell gap, thereby increasing the skin area. After removing the expansion sac, the newly increased skin soft tissue can be used for tissue repair and organ reconstruction. [0003] At present, for scars after burns or other situations that require skin reshaping, if scar reshaping or scar excision is required, skin soft tissue expanders are usually embedded in th...
