Description

Removable mask type negative pressure cyst drainage device

Technical Field

The utility model relates to a removable negative pressure cyst drainage device with a mouth mask, which is applicable to the drainage for treating bone cyst in oral cavity, jaw and face.

Background

For large jaw cysts, traditional partial jaw resection, scaling or enucleation may cause pathological or iatrogenic fractures, resulting in maxillofacial deformities; at the same time, it may cause the tooth loss and partial adjacent structure damage in the affected area, affecting the normal physiological function and life quality. Currently, there are three major factors recognized as the enlargement of jaw cysts: increased wall thickness, increased hydrostatic pressure, and increased bone resorption factor. Conservative surgical treatment methods for jaw cyst include pouch surgery, decompression surgery and negative pressure suction surgery. These therapies alter the internal environment of the cyst, eliminate intracavitary pressure, reduce or eliminate bone absorptive factors, thereby altering the lining epithelium of the cyst, reducing the cyst, and promoting adjacent bone remodeling. Clinical practice has shown that these conservative jaw cyst surgical treatments reduce the complications of traditional surgical treatments and result in better shape and functional recovery.

Conservative surgical treatment of jaw cyst is generally carried out in two stages, wherein cyst ostomy is performed under local anesthesia in the first stage, and a drainage tube is arranged for drainage; enucleation was performed at stage two after regular imaging to demonstrate significant cyst shrinkage.

Among various conservative surgical treatments, the negative pressure suction can effectively improve the swelling and malformation of the maxillofacial region of a patient, can reduce the cyst more quickly than other treatments, can shorten the treatment course, and has proved the clinical treatment effect. However, the negative pressure drainage device used at present has more problems, for example, the foreign matters are too obvious, the patient feels that the social contact is not easy to wear, and the drainage tube is difficult to fix. The cyst plug is a movable device, and the connection part of the cyst plug and the negative pressure drainage tube is large. The cyst stoma is easy to close too fast, and the length of the inner part of the cyst cavity is not easy to be adjusted according to the actual situation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a can take gauze mask formula negative pressure cyst drainage device, can take gauze mask formula drainage ware simple structure, contact cyst wall material has good compatibility with the tissue, can keep the drainage that the cyst was made a mouthful effectively unobstructed under the condition of protection patient privacy.

In order to achieve the purpose, the utility model adopts the following technical measures: the utility model provides a can take gauze mask formula negative pressure cyst drainage device which characterized in that: the drainage tube comprises an oral part and an oral part, wherein the oral part consists of a soft drainage tube, a long strip-shaped hard drainage rod, a base and a soft lining; the mouth outer part is arranged on a negative pressure cyst drainage device which can be taken off and is arranged in the mask, and the negative pressure cyst drainage device is connected with a soft drainage tube at the mouth inner part.

Preferably, the negative pressure cyst drainage device comprises a drainage tube, a three-way joint, a drainage bottle, a control valve and a vacuum pump together, wherein one end of the drainage tube penetrates through the removable mask and is then connected with the soft drainage tube at the inner part of the mouth, the other end of the drainage tube is connected with the drainage bottle through the three-way joint, the drainage bottle is connected with the vacuum pump through a connecting pipe with a screw, and the control valve is arranged on the connecting pipe.

Preferably, the soft drainage tube is connected with the drainage tube through a rubber hose.

Preferably, a rechargeable battery power supply connected with a vacuum pump is further arranged inside the removable mask.

Preferably, a power switch for controlling a power supply is further arranged outside the removable mask.

Preferably, the hard drainage rod and the base are both made of self-solidifying plastics.

Preferably, the diameter of the hard drainage rod is 4.0 to 5.5mm, and the length of the hard drainage rod is 11 to 15 mm; the diameter of the soft drainage tube is 3-4mm, and the diameter of the base is 2-3mm larger than that of the soft drainage tube.

Compared with the prior art, the utility model, have following advantage and effect: the utility model connects the inside and outside of the mouth by the rubber hose, and connects the inside and outside devices together by the rubber hose when going out, thereby achieving the hidden effect; when the device is at home, the patient can remove the rubber hose and the external device by himself without wearing the external device, thereby effectively utilizing the negative pressure drainage of the external device and the hidden effect of the removable mask to achieve good sac fluid drainage effect. On the one hand, the drainage device is hidden, and the shielding effect is good. On the other hand, the drainage design device is convenient for operating the negative pressure suction apparatus and actively reducing pressure. The continuous negative pressure that cyst negative pressure drainage ware produced makes the cyst dwindle gradually, and sclerotin constantly regenerates around the cyst wall, and cyst wall part bodiness is favorable to going on of cyst enucleation art, reduces the remaining chance of cyst epithelium, reduces the postoperative recurrence rate. The use method can be mastered by patients or their family members after being taught by medical staff for 2-3 minutes, and the drainage tube can be independently operated outside the hospital after being placed in the hospital. The portable solar energy collector has small volume and light weight, uses a battery as a power supply and can be carried about.
