Description

Anti-pressure sore braces

technical field

The utility model relates to a tooth pad for preventing pressure sores.

Background technique

Orotracheal intubation is an important means of clinically establishing artificial airway, implementing clinical anesthesia, and rescuing and treating critically ill patients. Good fixation of tracheal intubation and oral care for orotracheal intubation are two important factors related to the medical safety of patients. aspect.

The widely used method of fixed endotracheal intubation in clinical practice is to bind and fix the disposable tooth pad and endotracheal tube with medical tape, and then fix it on the patient’s cheek. The design defect of the tooth pad is that it is difficult for a single person to operate, and two people are required to cooperate. At the same time, the sweat and oil secreted by the patient's cheeks are easy to soak the tape, causing the tape to fall off. Insufficient fixation can easily cause catheter dislocation and oral mucosa damage. In severe cases, the catheter may prolapse, endangering the patient's life.

The important cause of ventilator-associated pneumonia is that after the patient is intubated, oral bacteria migrate into the lower respiratory tract and cause infection. Many studies have shown that the obstruction of tracheal intubation and dental pads, resulting in poor oral care is the cause of ventilator-associated pneumonia. one of the important reasons. On the one hand, the adhesive tape used to fix the tooth pad and cannula is easily soaked by the patient’s oral saliva and breeds bacteria. On the other hand, the volume of the tooth pad and cannula binding is relatively large, which affects the comfort of the patient and the observation of the oral cavity. It needs to be untied repeatedly. Fix and refix.

Contents of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of anti-pressure sore dental pad that is simple in structure, comfortable to use by patients, not easily infected, and easy to operate by medical workers.

The purpose of this utility model is achieved in that:

An anti-pressure sore tooth pad, which includes a support body in the middle, the support body is provided with an upper tooth fixing seat with an upward opening, and the support body is provided with a tooth lower fixing seat with a downward opening. The upper fixing seat and the lower tooth fixing seat are made of soft materials, and the middle part of the supporting body is provided with through holes in the front and rear directions.

Both the upper section and the lower section of the support body are provided with a transversely arranged stringing hole.

The through hole is provided with a locking sleeve, the front end of the locking sleeve is provided with a front convex ring, the front convex ring is located outside the support body, and the rear end of the locking sleeve is provided with a rear convex ring. A cavity is provided in the support body behind the rear convex ring, and springs arranged front and rear are arranged in the cavity, the rear end of the spring is connected to the rear side wall of the cavity, and the front end of the spring is connected to the rear convex ring. A locking top block is provided forward on the rear convex ring, and the rear side of the rope hole has a locking channel for the locking top block to move back and forth. When the spring is in a natural state, the front half of the locking top block segment is located in the lanyard hole.

The opening of the tooth upper fixing seat is a triangular opening obliquely backward and upward, and the opening of the tooth lower fixing seat is a vertically downward rectangular opening.

The surface near the inner side of the triangular opening of the upper tooth fixing seat is a concave arc surface.

Compared with the prior art, the beneficial effects of the utility model are:

The pressure sore prevention tooth pad of the utility model has the advantages of simple structure, comfortable use by patients, not easily infected, and convenient operation by medical workers.

detailed description

Referring to Figures 1 to 3, the utility model relates to an anti-pressure sore tooth pad, which includes a support body 1 in the middle, and the support body 1 is provided with an upper tooth fixing seat 2 with an upward opening. There is a tooth lower fixing seat 3 with an opening downward. The tooth upper fixing seat 2 and the tooth lower fixing seat 3 are made of silica gel or other soft materials. The opening of the tooth upper fixing seat 2 is obliquely backward. The upper triangular opening, the opening of the lower tooth fixing seat 3 is a vertically downward rectangular opening. The surface near the inner section of the triangular opening of the upper tooth fixing seat 2 is a concave arc surface.

The middle part of the support body 1 is provided with a through hole 4 in the front and rear direction, the through hole 4 is provided with a locking sleeve 5, the front end of the locking sleeve 5 is provided with a front convex ring 6, and the front convex ring 6 Located outside the support body 1, the rear end of the locking sleeve 5 is provided with a rear protruding ring 7, and a cavity is provided in the support body 1 behind the rear protruding ring 7, and a front and back arrangement is arranged in the cavity. Spring 8, the rear end of the spring 8 is connected to the rear side wall of the cavity, the front end of the spring 8 is connected to the rear convex ring 7, and the rear convex ring 7 is provided with a locking top block 9 forward, and the support Both the upper front section and the lower front section of the body 1 are provided with a transversely arranged rope-threading hole 10 , and the rear side of the rope-threading hole 10 has a locking passage for the locking top block 9 to move back and forth. When the anti-pressure sore dental pad is used for children, a handle is installed forward on the lower part of the front side of the anti-pressure sore dental pad, and the handle is used for holding operation. The tablet is used to hold the tongue down.

working principle:

When the spring 8 was in the natural state, the first half of the locking jack 9 was located in the rope hole 10, the first half of the locking sleeve 5 stretched out of the support body 1, and the front end between the front convex ring 6 and the front end of the support body 1 There is a gap between them. When in use, the anti-pressure sore tooth pad is installed in the patient's mouth, the upper row of teeth of the patient is embedded in the triangular opening of the upper tooth holder 2, and the lower row of teeth of the patient is embedded in the rectangular opening of the lower tooth holder 3, Stomach tube and other small tubes can pass through the locking sleeve 5 to save oral space, and the trachea can enter the oral cavity from the outside of the anti-pressure sore tooth pad, and press the front convex ring 6 to the front convex ring 6 to be close to the support body 1 The outer front side wall makes the locking sleeve 5 move backwards. At this time, the rear convex ring 7 compresses the spring 8, and the locking top block 9 moves backwards in the locking channel and finally leaves the threading hole 10, and then the rope is threaded at this time. Put a rope through the hole 10, use the rope to fasten the anti-pressure sore tooth pad and the trachea, and finally loosen the front convex ring 6, due to the elastic force of the spring 8, the locking top block 9 resets, and the locking top block is in the rope threading hole Hold the rope within 10, fix the rope, and the anti-pressure sore dental pad and the trachea can be quickly tied and fastened.
