Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0024] The invention discloses an adjustable negative pressure suction device for sinus tract wounds. figure 1 As shown, it includes a cushion 1, a water injection pipe 2, and an air suction pipe 3.

[0025] Wherein, the soft pad 1 is provided with a cavity 101. When the sinus wound surface needs to be flushed, the cavity 101 is used to temporarily store the flushing fluid so that the flushing fluid can be discharged through the through hole 102; when the waste liquid needs to be absorbed, the cavity 101 is used In order to form a negative pressure environment, the waste liquid near the sinus wound can enter the cav...

Abstract

The invention discloses an adjustable sinus tract wound surface negative pressure suction device which comprises a soft cushion, a water injection pipe and an air suction pipe. A cavity is formed in the soft cushion, a plurality of through holes which are evenly distributed in the circumferential direction are formed in the side wall of the soft cushion, and the cavity is communicated with the outside through the through holes. The water injection pipe is connected with the soft cushion and is communicated with the cavity; the air suction pipe is connected with the side wall of the soft cushion and communicated with the cavity, the upper face and the lower face of the soft cushion are both connected with first anti-pressing lips used for protecting the soft cushion, and the end, away from the soft cushion, of the water injection pipe is connected with a flushing pipe network used for providing flushing fluid so that the sinus tract wound can be flushed. Through the arrangement of corresponding mechanisms, the sinus tract wound surface can be effectively cleaned, waste liquid near the sinus tract wound surface can be completely sucked out, the waste liquid is not prone to being left in the sinus tract wound surface, the negative pressure environment of the sinus tract wound surface is guaranteed, the healing efficiency of the sinus tract wound surface can be guaranteed, and pain of a patient is relieved.

Description

technical field [0001] The invention belongs to the technical field of disposable chronic wound surgical materials, and in particular relates to an adjustable sinus tract wound negative pressure suction device. Background technique [0002] Sinus tract refers to a latent blind duct that opens on the body surface and does not communicate with hollow organs in the body formed after infection and necrosis of body tissues are excreted from the body surface. It can occur in soft tissue, fat, muscle or even bone. quality etc. The common ones are abdominal wall sinus caused by poor drainage after abdominal incision infection or foreign bodies left in the incision, chronic sinus formed by osteonecrosis caused by fracture or other reasons, and chronic sinus formed by residual foreign bodies after trauma or surgery. [0003] When repairing sinus tract wounds, negative pressure suction devices are generally used. However, when the existing negative pressure suction devices are used, t...
