Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a pressure-applying device for parotid gland postoperative incisions. Background Technique

[0002] Parotid gland tumors are a common maxillofacial disease. Surgical resection is the preferred treatment method for parotid gland tumors, and the incidence of postoperative salivary fistula is relatively high. After parotid gland tumor surgery, pressure dressing is used to reduce the occurrence of salivary fistula.

[0003] Currently, most of the pressure-applying methods used clinically are pressure headgear. It uses an elastic bandage to wrap the whole head for pressure application. Although the pressure application effect is achieved, the disadvantages are also obvious: ① There is too much unnecessary pressure application area, which affects the comfort and aesthetics of patients after surgery; ② The pressure application duration is 2-3 weeks after surgery, which affects the patient's return to normal social life and makes it difficult for the patient to adhere to use, thus increasing the incidence of postoperative complications; ③ When using the pressure headgear during eating, it causes limited mouth opening, and there is a risk of nutritional imbalance after surgery. If not used, the continuity of pressure dressing is lost, and the incidence of complications increases; ④ The pressure headgear is affected by the face shape and head shape, and there is a risk of uneven force, and the ideal pressure application effect cannot be achieved.

[0004] With the development of technology, there is a need for a new pressure-applying method in clinical practice to solve the disadvantages of the pressure headgear without affecting pressure application and reduce the occurrence of postoperative complications. Content of the Utility Model

[0022] The present utility model will be specifically described below with reference to the accompanying drawings.

[0023] As shown in the attached Figure 1 to the attached Figure 5 ,

[0024] Embodiment 1:

[0025] A parotid gland postoperative incision compression device includes a housing 1 that covers the entire parotid gland area of the patient. The housing 1 can be made of lightweight plastic material, and can be a rigid material or a flexible material, but the flexibility should not be too soft. There is a cavity inside the housing 1. An inflation port 2 connecting to its internal cavity is provided on the front of the housing 1. A one-way inflation valve is provided on the inflation port 2. A plurality of connection holes 3 communicating with the cavity are evenly distributed on the back of the housing 1. A small airbag 4 or a hole plug 5 can be inserted into the connection holes 3. According to the position to be compressed in the patient's parotid gland area, the small airbag 4 is inserted into the connection holes 3 in the corresponding area, and the hole plug 5 is inserted into the non-compression area. A flexible pad 6 is provided on the outer ring of the housing 1. The flexible pad 6 contacting the patient's facial skin can avoid rigid extrusion. The flexible pad 6 is connected to a binding and fixing mechanism 7, and the binding and fixing mechanism 7 fixes the housing 1 on the patient's face.

[0026] During actual operation, due to the differences in facial features of different patients, the patient first tries on the parotid gland postoperative incision compression device of the present utility model, which is convenient for the doctor to understand the area to be compressed in the patient's parotid gland area corresponding to the housing 1. The doctor installs the small airbag in the area to be compressed, and the connection holes 3 that do not need to install the small airbag are blocked with the hole plug 5. The housing 1 is inflated through the one-way inflation valve. After the small airbag 4 bulges, pressure is applied. Since the detachable small airbag is adopted, the doctor can adjust the size of the compression area according to the actual situation, avoiding damage to the parts that do not need to be compressed.

[0027] Embodiment 2:

[0028] The binding and fixing mechanism 7 includes a head-mounted mesh 71. Fixing bands 72 are provided at both ends of the head-mounted mesh 71. The fixing band 72 close to the housing 1 is connected to the upper middle position of the flexible pad 6, and the fixing band 72 on the other side is connected to one end of a traction band 73. The other end of the traction band 73 bypasses the patient's chin position and is connected to the lower right position of the flexible pad 6. The head-mounted mesh 71, the traction band 73 and the flexible pad 6 form an annular structure that fits around the patient's head and chin positions for fixation. It has high stability, small facial area occlusion, and is more beautiful.

[0029] Preferably, a first through hole 74 for the patient's ear to pass through is provided on the fixing band 72, and a second through hole 75 for the patient's chin to pass through is provided on the traction band 73.

[0030] Example 3:

[0031] The restraint and fixation mechanism 7 further includes a first reinforcement strap 76 and a second reinforcement strap 77.
