Embodiment Construction

[0040] The present invention will be further described below in conjunction with drawings and embodiments.

[0041] like figure 1 and figure 2 As shown, this embodiment provides a postoperative compression and drainage device for the parotid gland, including a dressing layer 1 , a negative pressure drainage assembly 2 and a sleeve 3 . The tube cover 3 is arranged through the dressing layer 1, and the dressing layer 1 fits the patient's face and covers the wound to fix the tube cover 3. One end of the sleeve 3 is placed in the patient's wound, and the other end is detachably connected to the negative pressure drainage assembly 2, and the negative pressure drainage assembly 2 is communicated with the patient's wound for sucking the liquid exuded from the wound.

[0042] In one embodiment, the sleeve 3 and the negative pressure drainage assembly 2 are socketed, so that the negative pressure drainage assembly 2 can be actively separated from the sleeve 3 when pulled by an exter...

Abstract

The invention discloses a parotid gland post-operation compression drainage device and a using method. The parotid gland post-operation compression drainage device comprises a dressing layer, and the dressing layer is attached to the face of a patient and covers a wound; a negative pressure drainage assembly; the pipe sleeve telescopically penetrates through the dressing layer, one end of the pipe sleeve is arranged on the wound of the patient, the other end of the pipe sleeve is detachably connected with the negative pressure drainage assembly, and the negative pressure drainage assembly is communicated with the wound of the patient to suck liquid exuded from the wound. Through the cooperation of the pipe sleeve and the dressing layer, the connecting structure fixed to the wound of the patient is established, the negative pressure drainage assembly is detachably connected with the connecting structure in a butt joint mode, the negative pressure drainage assembly is communicated with the wound of the patient, and then the negative pressure drainage operation can be completed. Moreover, when the negative-pressure drainage assembly is pulled by external force, the negative-pressure drainage assembly can be disconnected from the pipe sleeve to prevent the wound from being pulled to cause pain to the patient, and the negative-pressure drainage assembly can be reconnected with the pipe sleeve to continue negative-pressure drainage treatment after being disinfected.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a postoperative compression and drainage device for the parotid gland and a use method thereof. Background technique [0002] Parotid gland tumor is one of the common diseases in oral and maxillofacial surgery, with very complex pathological types and high incidence. Regional resection of parotid gland tumors is a common surgical procedure in oral and maxillofacial surgery. However, due to the rich blood supply of maxillofacial tissues, postoperative wound bleeding may lead to hematoma formation. Hematoma enlargement affects wound healing, and in severe cases, it will affect the patient's breathing. [0003] At the same time, there is a high probability of salivary fistula complications after parotid gland tumor resection. Salivary fistula is a common disease in oral and maxillofacial surgery. The exuded fluid will irritate the wound, causing redness, swelli...
